Description

June 17, 1958 INVENTOR 'Willium F. Aubuchon United States Patent 2,838,831 HOLDERS FOR SLIDE FASTENERS William F. Aubuchon, Jackson, Miss, assignor to Scovill Manufacturing Company, Waterbury, Conn., a corporation of Connecticut Application February 2, 1956, Serial No. 563,047
' 4 Claims. c1. 29-284) This invention relates to an assembly machine for use in the .manufacture of slide fasteners generally known as zippers, and particularly to a fixture or clamping device for holding the slider while the zipper chain is being assembled therethrough.
In the art of manufacturing zippers the fastener elements are attached to the beaded edge of the tape and a pair of such zipper stringers either before or after they are attached to parts of a garment are assembled by pulling through the usual slider.
The primary object of this invention is to provide a simple, effective and inexpensive holding device to hold the slider while the operator is free to use both hands in pulling the zipper stringers through the slider.
In prior slider holders the devices were rather cumbersome in requiring that some part of the machine be manually operated before the slide could be assembled into the machine, and also the character of the holder was suclras to interfere with the free use of the operators hands in manipulating the zipper stringers through the guide channels in the slider member.
Another object of my invention is to provide a holder into which the slider can be quickly assembled without the necessity of requiring the operator to manipulate any part of the holder and wherein the holder will not interfere with the free use of the operators hands in assembling the zipper chain through the clamped slider.
With this and other objects in view the invention will be readily understood from the following detailed description of one preferred embodiment shown in the accompanying drawing, wherein:
Fig. 1 is a perspective view of a fixture for holding a slider while the zipper stringers are being threaded therethrough.
Fig. 2 is a similar view with the slider and zipper stringers removed.
Fig. 3 is a side view of the fixture with the upper portion in section.
Fig. 4 is a partial plan and sectional view taken along the line of 4-4 of Fig. 3, and
Fig. 5 is a sectional view through a slider showing the upper half with the pull tab attached thereto.
Referring now to the drawing, the numeral refers to a standard having a base pedestal 11 by means of which the fixture may be mounted upon any suitable support. The upper end of the standard 10 is formed with an integral offset arm 12 terminating in a reduced nose 13 positioned a substantial distance from the stand ard 10. An L-shaped bracket 14 is attached to the forward face of the standard 10 as by screws 15 and is formed with a support arm 16 extending parallel to and in spaced relationship to the offset arm 12.
A typical slider 17 is shown which my fixture is adapted to hold. This slider has a connecting neck 18 at one end formed with an exterior indented recess 19. The slider 17 is provided with the usual pull tab 20 hingedly Patented June 17, 19.58
connected thereto and having an opening 21 adjacent its free end. The slider 17 functions in the well known manner to connect and disconnect the interfitting elements of a pair' of zipper stringers 22 and 23.
The nose end 13 of the offset arm 12 is provided with an end recess 24 for receiving the slider 17- neck end first, and projecting into the recess is a longitudinal rib 25 formed as an integral part of the arm 12. The rib 25 is adapted to project into the recess 19 of the slider neck 18 to stabilize the position of the slider during the asesmbly of the zipper stringers.
The upper surface of the support arm 16 is formed with a channel 26 in which is telescopically received the slider pull tab 20 when the slider is being assembled into the fixture. In order to hold the slider within the fixture a detent pin 28 is slidably mounted in the offset arm 12 and is operated by a lever 29 positioned in a longitudinal channel 30 in the upper end of said arm 12 and pivoted thereto as by pivot pin 31. The lever 29 is normally urged in a counterclockwise direction by a coiled spring 32 retained in a socket recess 33 in the upper end of the standard 10.
The lower end of the detent pin 28 has a beveled surface 34 facing toward the entrance end of the fixture. The entrance end refers to that end of the fixture where the slider is inserted. The detent pin 28 is held against turning by reason of the connection between said pin 28 and the lever 29 which specifically is a cross slot 35 in said pin engaged by a squared projection 36 on end of lever 29. The spring operated lever 29 urges. the detent pin 28 downwardly in its respective recess so that its sharp beveled end 34 normally rests against the upper end of the channel 26. The outer end of the lever 29 is formed with a biased portion 37 that serves as a handle for operating said lever.
In the operation of this fixture the pull tab 20 of the slider is first telescopically inserted into the support arm channel 26 and when the free end of said tab 20 engages the beveled end 34 of the detent pin it will automatically force the latter upwardly against the influence of the spring urged lever 29 until the opening 21 in said pull tab aligns with the pin 28 whereupon said pin will automatically drop into said opening and lock the slider in position in the recess 24 in the ofiset arm 12 for holding the slider during the assembly of the zipper stringers therethrough. To release the slider it is only necessary to press downwardly on the handle portion 37 of the lever 29 which will withdraw the detent pin upwardly to release the pull tab and permit withdrawal of the zipper stringers with the attached slider.
It will be apparent that in having the slider supported in the offset arms a substantial distance from the support standard provides for considerable amount of free area about the held slider that makes it easier and allows for a faster operation in assembling the zipper stringer through the slider. This arrangement is particularly helpful when the garment sections are attached to the stringers.
Another advantage in expediting the assembly operation is that the slider can be inserted into the fixture without requiring the operator to operate any part of the device.
Minor changes in details and construction and arrangement of parts may be made without departing from the scope of the present invention as set forth in the appended claims.
I claim:
