Extension Spring Design

August 28th, 2018

Helical extension springs exert a force by pulling or stretching them.  Usually, they are made from round wire and are close-wound with the initial tension between the coils.  Their ends can be formed with loops in many varieties to attach to their applications.

The History of Watch Springs

August 14th, 2018

The history of companies is built by many short stories; some boring, some not. We’re going to try and tell the not-so-boring ones (in our humble opinion) about Katy Spring & Mfg., Inc.; a company in Katy Texas that started with a conversation that ended something like this; “Why not.”

These are the stories about Katy Spring, small bits of a bigger story that started in 1999. The stories are still unfolding new chapters every day, thanks to our wonderful customers. It’s written for our customers and future customers so that they can get to know our company, our employees, some historical background and philosophy a little better.

The stories are not told in chronological order. This blog is more of a “Readers Digest” about Katy Spring, written in whatever random order they appear. So, without further ado, let’s get started with the next read which is titled; “The History Watch Springs”

Mainsprings appeared in the first spring powered clocks, in 15th century Europe. It replaced the weight hanging from a cord wrapped around a pulley, which was the power source used in all previous mechanical clocks. Around 1400 coiled springs began to be used in locks, and many early clockmakers were also locksmiths. Springs were applied to clocks to make them smaller and more portable than previous weight driven clocks, evolving into the first pocket watches by 1600. Many sources erroneously credit the invention of the mainspring to the Nuremberg clockmaker Peter Henlein.  However, many references in 15th century sources to portable clocks ‘without weights’, and at least two surviving examples, show that spring driven clocks existed by the early years of that century.

The first mainsprings were made of steel without tempering or hardening processes. They didn’t run very long, and had to be wound twice a day. Henlein was noted for making watches that would run 40 hours between windings. The modern watch mainspring is a long strip of hardened and blued steel, or specialized steel alloy, 20–30 cm long and 0.05-0.2 mm thick. The mainspring in the common 1-day movement is calculated to enable the watch to run for 36 to 40 hours, i.e. 24 hours between daily windings with a power-reserve of 12 to 16 hours, in case the owner is late winding the watch. This is the normal standard for hand-wound as well as self-winding watched, used in clocks meant to be wound weekly, provide power for at least 192 hours but use longer mainsprings and bigger barrels.  Lock mainsprings are similar to watch springs, only larger.

Since 1945, carbon steel alloys have been increasingly superseded by newer special alloys (iron, nickel and chromium with the addition of cobalt, molybdenum, or beryllium), and also by coldrolled alloys (‘structural hardening’). Known to watchmakers as ‘white metal’ springs (as opposed to blued carbon steel), these are stainless and have a higher elastic limit. They are less subject to permanent bending (becoming tired’) and there is scarcely any risk of their breaking. Some of them are also practically non-magnetic.

In their relaxed form, mainsprings are made in three distinct shapes:

  • Spiral coiled: These are coiled in the same direction throughout, in a simple spiral.
  • Semi-reverse: The outer end of the spring is coiled in the reverse direction for less than one turn (less than 360°).
  • Reverse (resilient): the outer end of the spring is coiled in the reverse direction for one or more turns (exceeding 360°).

The semi-reverse and reverse types provide extra force at the end of the running period, when the spring is almost out of energy, in order to keep the timepiece running at a constant rate to the end

he mainspring is coiled around an axle called the arbor, with the inner end hooked to it. In many clocks, the outer end is attached to a stationary post. The spring is wound up by turning the arbor, and after winding its force turns the arbor the other way to run the clock. The disadvantage of this open spring arrangement is that while the mainspring is being wound, its drive force is removed from the clock movement, so the clock may stop. This type is often used on alarm clocks, music boxes and kitchen timers where it doesn’t matter if the mechanism stops while winding. The winding mechanism always has a ratchet attached, with a pawl (called by clockmakers the click) to prevent the spring from unwinding.

In the form used in modern watches, called the going barrel, the mainspring is coiled around an arbor and enclosed inside a cylindrical box called the barrel which is free to turn. The spring is attached to the arbor at its inner end, and to the barrel at its outer end. The attachments are small hooks or tabs, which the spring is hooked to by square holes in its ends, so it can be easily replaced.

The mainspring is wound by turning the arbor, but drives the watch movement by the barrel; this arrangement allows the spring to continue powering the watch while it is being wound. Winding the watch turns the arbor, which tightens the mainspring, wrapping it closer around the arbor. The arbor has a ratchet attached to it, with a click to prevent the spring from turning the arbor backward and unwinding. After winding, the arbor is stationary and the pull of the mainspring turns the barrel, which has a ring of gear teeth around it. This meshes with one of the clocks gears, usually the center wheel pinion and drives the wheel train. The barrel usually rotates once every 8 hours, so the common 40-hour spring requires 5 turns to unwind completely.

The History of Katy Spring | Pogo Stick

July 10th, 2018

 

The history of companies is built by many short stories; some boring, some not. We’re going to try and tell the not-so-boring ones (in our humble opinion) about Katy Spring & Mfg., Inc.; a company in Katy Texas that started with a conversation that ended something like this; “Why not.”

These are the stories about Katy Spring, small bits of a bigger story that started in 1999. The stories are still unfolding new chapters every day, thanks to our wonderful customers. It’s written for our customers and future customers so that they can get to know our company, our employees, some historical background and philosophy a little better.

The stories are not told in chronological order. This blog is more of a “Readers Digest” about Katy Spring, written in whatever random order they appear. So without further ado, let’s get started with the next read which is titled; “The History of the Pogo Stick”

Every spring that Katy Spring manufactures was part of an invention at one time. That’s why Katy Spring treats every inquiry with respect.

With the number of inventors that we are approached with yearly, Katy Spring does have a system to help potential customers find what they’re looking for, whether it’s from Katy Spring or not. It’s tough to determine which products will succeed and which ones will not, so we treat all projects as if they have good potential. Which brings me to the Pogo Stick.

George Hansburg patented the first pogo stick in America in 1919 at the request of Gimble’s Department Store. It seems that Gimbles had ordered a batch of pogo sticks from Germany, but the toys rotted in the dampness of the ship during the long voyage to America. Gimble’s contacted Hansburg and requested that he produce a similar toy but one that would hold up in a variety of conditions.

Hansburg did as he was asked and patented the modern pogo stick. He began producing the toy from his manufacturing facility in Ellenville, New York, where they continue to be made even today.

Pogo sticks became increasingly popular during the twenties. In fact, George Hansburg taught the dancers of the Zeigfeld Follies how to use the pogo stick, and that created a new use for the pogo stick. Dancers and chorus lines throughout the country begane utilizing pogo sticks in their shows and routines. People found more ways to include pogo sticks in their activities. Even weddings were performed on pogo sticks.

It wasn’t too long before people were trying to break one another’s pogo records, with jumping contests and official contests.

After World War II, in 1947, Hansburg developed a new kind of pogo stick out of metal. The spring lasted much longer than the prior design, so Hansburg named the updated pogo stick the Master Pogo. This pogo stick became the company’s best seller and remains the best-selling pogo stick today.

Although pogos never again reached the popularity that they had in the 1920s, they never totally went away either. In the 1970s, George Hansburg sold his company to local businessman Irwin Arginisky. Other companies have tried to make pogo sticks that equal Hansurg’s sticks in quality and desirability but none ever quite achieved the success of the original pogo stick.

There have been many attempts to set records with the pogo stick over the years since its invention. Some of the records that were made decades ago have yet to be broken. Some of the world records are:

· Ashrita Furman of Jamaica set a distance record of 23.11 miles in just under 12½ hours

· The record for the most consecutive jumps is held by Gary Stewart. He had 177,737 consecutive jumps in 1990. He was on the pogo stick for a total of 20 hours and 20 minutes

· The highest pogo stick jump was achieved by Fred Grzybowski at eight feet.

The history of the pogo stick isn’t very complete, and there are a lot of details that will always be unknown. What is known is that pogo sticks have given countless hours of enjoyment to the young and young at heart for decades. It is one of those old fashioned toys that will always be in style.

The History of the Slinky

June 12th, 2018

The History of Katy Spring

The history of companies is built by many short stories; some boring, some not. We’re going to try and tell the not-so-boring ones (in our humble opinion) about Katy Spring & Mfg., Inc.; a company in Katy Texas that started with a conversation that ended something like this; “Why not.”

These are the stories about Katy Spring, small bits of a bigger story that started in 1999. The stories are still unfolding new chapters every day, thanks to our wonderful customers. It’s written for our customers and future customers so that they can get to know our company, our employees, some historical background and philosophy a little better.

The stories are not told in chronological order. This blog is more of a “Readers Digest” about Katy Spring, written in whatever random order they appear. So without further ado, let’s get started with the next read which is titled; “The History of the Slinky”

A Slinky is a pre-compressed, toy helical spring invented by Richard James in the early 1940s. It can perform a number of tricks, including traveling down a flight of steps end-over-end as it stretches and re-forms itself with the aid of gravity and its own momentum, or appear to levitate for a period of time after it has been dropped. These interesting characteristics have contributed to its success as a toy in its home country of the United States.

The Slinky was originally demonstrated at Gimbels department store in Philadelphia in November 1945. The toy was a hit, selling its entire inventory of 400 units in ninety minutes. James and his wife Betty formed James Industries in Clifton Heights, Pennsylvania to manufacture Slinky and several related toys such as the Slinky Dog and Suzie, the Slinky Worm. In 1960, James’s wife Betty became president of James Industries, and, in 1964, moved the operation back to Hollidaysburg, Pennsylvania. In 1998, Betty James sold the company to Poof Products, Inc.

Slinky was originally priced at $1, but many paid much more due to price increases of spring steel throughout the state of Pennsylvania; it has, however, remained modestly priced throughout its history as a result of Betty James’ concern about the toy’s affordability for poor customers. Slinky has been used other than as a toy in the playroom: it has appeared in the classroom as a teaching tool, in wartime as a radio antenna, and in physics experiments with NASA. Slinky was inducted into the National Toy Hall of Fame at The Strong in Rochester, New York, in 2000. In 2002.

Slinky (1946)

In 1943, Richard James, a naval mechanical engineer stationed at the William Cramp and Sons shipyards in Philadelphia, was developing springs that could support and stabilize sensitive instruments aboard ships in rough seas.[2][3] James accidentally knocked one of the springs from a shelf, and watched as the spring “stepped” in a series of arcs to a stack of books, to a tabletop, and to the floor, where it re-coiled itself and stood upright.[4][5] James’s wife Betty later recalled, “He came home and said, ‘I think if I got the right property of steel and the right tension; I could make it walk.'”[6] James experimented with different types of steel wire over the next year, and finally found a spring that would walk. Betty was dubious at first, but changed her mind after the toy was fine-tuned and neighborhood children expressed an excited interest in it.[5] She dubbed the toy Slinky (meaning “sleek and graceful”), after finding the word in a dictionary,[4][5] and deciding that the word aptly described the sound of a metal spring expanding and collapsing.[7]

With a US$500 loan, the couple formed James Industries (originally James Spring & Wire Company), had 400 Slinky units made by a local machine shop, hand-wrapped each in yellow paper, and priced them at $1 a piece.[5] Each was 2 1?2″ tall, and included 98 coils of high-grade blue-black Swedish steel.[8] The James’ had difficulty selling Slinky to toy stores but, in November 1945, they were granted permission to set up an inclined plane in the toy section of Gimbels department store in Philadelphia to demonstrate the toy. Slinky was a hit, and the first 400 units were sold within ninety minutes.[5][8] In 1946, Slinky was introduced at the American Toy Fair.

Stainless- Steel Extension springs

Extension springs are closed-coiled helical springs that extend under a pulling force. Many design considerations must be made with extension springs including; initial tension, stress and deflection of hooks, hook end types.

Spring reel is used to hold large-diameter spring wire .362 oil-tempered

May 31st, 2018

This spring reel is used to hold large-diameter spring wire (in this video we’re seeing .362 oil-tempered) while it’s being fed into a CNC spring coiler.
Ultimately this wire will be wound into a compression spring which is used in oil regulation equipment.
Changing out larger, raw material spring coils can sometimes require two people and take up to an hour and a half to change.
Smaller spring reels can be changed out in a matter of minutes.

Garter spring made from .040″ 302 stainless steel wire.

May 22nd, 2018

This week’s capability video features a garter spring made from .040″ 302 stainless steel wire.

A garter spring is a coiled spring that is typically connected at each end to create a circular shape.

Garter springs are used in oil seals, shaft seals, belt-driven motors and electrical connectors.
Because of the length, a steel trough is used to assist supporting the garter spring as it is coiled off the machine.

The History of Spring-Loaded Mouse Traps

May 11th, 2018

The History of Katy Spring

The history of companies is built by many short stories; some boring, some not. We’re going to try and tell the not-so-boring ones (in our humble opinion) about Katy Spring & Mfg., Inc.; a company in Katy Texas that started with a conversation that ended something like this; “Why not.”
These are the stories about Katy Spring, small bits of a bigger story that started in 1999. The stories are still unfolding new chapters every day, thanks to our wonderful customers. It’s written for our customers and future customers so that they can get to know our company, our employees, some historical background and philosophy a little better.

The stories are not told in chronological order. This blog is more of a “Readers Digest” about Katy Spring, written in whatever random order they appear. Without further ado, let’s get started with the next read which is titled; “The History of Spring-Loaded Mouse Traps”
Most of us our familiar with the phrase; “No need to reinvent the mouse trap.” When in fact, mouse traps have been reinvented or improved several times. And it all started with springs.
The first lethal trap was a set of spring-loaded, cast-iron jaws named “Royal No. 1”. The trap [was patented on 4 November 1879 by James M. Keep of New York, US patent 221,320. This is not the first mousetrap of this type, but the patent is for this simplified, easy to manufacture, design, which it relied on the force of a wound spring rather than gravity to capture a mouse.
The jaws operated by a coiled spring and the triggering mechanism is between the jaws, where the bait is held. The trip snaps the jaws shut, killing the mouse.

Lightweight traps of this style are now constructed from plastic. These traps do not have a powerful snap like other types. They are safer for the fingers of the person setting them than other lethal traps and can be set with the press on a tab by a single finger or even by foot.
Another spring-loaded mousetrap was first patented by William C. Hooker of Abington, IL. who received US patent 528671 for his design in 1894. A British inventor, James Atkinson a similar trap called the “Little Nipper” in 1898, including variations that had a weight-activated treadle as the trip. It trapped mouse in spring-loaded bar trap

In 1899, Atkinson patented a modification of his earlier design that transformed it from a trap that goes off by a step on the treadle into one that goes off by a pull on the bait.[8] The similarity of the latter design with Hooker’s of 1894 may have contributed to a common mistake of giving priority to Atkinson.

It is a simple device with a heavily spring-loaded bar and a trip to release it. Cheese may be placed on the trip as bait but other food such as oats, chocolate, bread, meat, butter and peanut butter are more commonly used. The spring-loaded bar swings down rapidly and with great force when anything, usually a mouse, touches the trip. The design is such that the mouse’s neck or spinal cord can be broken, or its ribs or skull crushed, by the force of the bar. The trap can be held over a bin and the dead mouse released into it by pulling the bar. In the case of rats which are much larger than mice, a much larger version of the same type of trap is used to kill them. Some spring mousetraps have a plastic extended trip. The larger trip has two notable differences over the smaller traditional type: increased leverage, which requires less force from the rodent to trip it; and the larger surface area of the trip increases the probability that even the most cunning of rodents will set off the trap. The exact latching mechanism holding the trip varies a lot and some need to be set right at the edge in order to be sensitive enough to catch cautious mice.

In 1899, John Mast of Lititz, Pennsylvania, filed a U.S. patent for a modification of Hooker’s design that can be “readily set or adjusted with absolute safety to the person attending thereto, avoiding the liability of having his fingers caught or injured by the striker when it is prematurely or accidentally freed or released.” He obtained the patent on 17 November 1903. After William Hooker had sold his interest in the Animal Trap Company of Abingdon, Illinois, and founded the new Abingdon Trap Company in 1899, the Animal Trap Company moved to Lititz, Pennsylvania, and fused with the J.M. Mast Manufacturing Company in 1905. The new and bigger company in Lititz, however, retained the name Animal Trap Company. Compounding these different but related patents and companies may have contributed to the widespread mis-attribution of priority to Mast rather than Hooker.

Since the spring-loaded mouse traps, there have been other types of traps invented including; electric traps, live-capture mouse traps, glue traps, barrel traps and disposable traps.
