Application July 1, 1949, Serial No. 102,464
6 Claims.
This invention relates to an apparatus for mounting end stops on slide fastener stringers.
It is an object of my invention to provide an apparatus of the character described which is positive and eflicient in operation and is of simple construction;
Other objects of my invention will in part be obvious and in part will be pointed out hereinafter.
My invention accordingly consists in the features of construction, combinations of elements and arrangements of parts which will be exemplified in the construction hereinafter described and of which the scope of application will be indicated in the appended claims.
In the accompanying drawings in which is shown one of the various possible embodiments of my invention,

Figs. 4 and 5 are enlarged fragmentary sectional views taken substantially along the lines 44 and 5-5 respectively of Fig. 1;
Fig. 6 is an enlarged sectional view taken substantially along the line 6-6 of Fig. 2, the same being illustrative of the position of the'principal operating parts of the machine at the start of an attaching cycle;
Figs. '7 and 8 are views similar to Fig. 6 but showing the positions of said parts at two later points of the cycle;
Fig. 9 is a view taken substantially along the line 9-9- of Fig. 7; and
Fig. 10 is a perspective view of an end stop prior to attachment thereof.
Referring now in detail to' the drawings, the reference numeral 2!! denotes an apparatus embodying my invention. Said apparatus includes a suitable feeding mechanism (not shown) for holding a plurality of unattached slide fastener end stops in a hopper, for withdrawing end stops from the hopper in a predetermined position and for transferring them to a gravity chute consisting of a. pair of vertical coplanar plates 22, 24, having a pair of juxtaposed edges which define Any suitable mechanism of the character described can be employed and, as an example thereof, reference is made to my copending application, Serial No. 13,406, filed March 6, 1948, for a Method and Apparatus for Attaching End Stops on Slide Fastener stringers wherein one such mechanism is illustrated.
Ihe apparatus 28 is designed to attach end stops 28 (see Fig. 10) which essentially comprise a U-shaped member constituting a base strap 30 from whose two ends stub arms 32, 36 extend in the same direction. Each arm is bifurcated to form a pair of inwardly curved, outspread fingers 36, 3%. The arms 32, 34 are substantially perpendicular to the base 38 and the distance between the tips of the fingers 30 is slightly in excess of the thickness of the beaded edge of the slide fastener stringer on which an end stop is to be mounted.
The unattached end stops 28 gravitate down the chute 26 with their base straps 30 between the juxtaposed edges of the plates 22, 24' and with their arms and fingers 32, 34, 36, 38 straddling the forward plate 24. The width of the longitudinal zone of this forward plate thus embraced by the arms and fingers, is slightly less than the distance between said arms (see Fig. 2) so that descent of the end stops in the chute is positionally controlled.
The plates 22, 24 are secured in some suitable fashion, for example by screws 40, toa block 42 mounted on the base 44 of the machine. Said block includes a bed 46 on which a hardened insert-type anvil 8 is supported at the attaching station. This anvil is directly below a vertically reciprocable die 5!; which is slidable in a journal 52 integral with the block 42.
The bed 46 extends from beneath the deliver end of the chute 26 to the anvil 48. The fiat upper face of said bed is uniformly spaced below the straight bottom end of the forward chute plate 24 a distance slightly greater than the width of the base strap 3!! (the height of said strap in the position shown in Fig. 8) so that said base strap can ride forwardly to the attaching station in erect position through the space between the chute and bed.
The part of the bed between the chute and anvil is formed with a pair of parallel slots 54 which are spaced apart a proper distance to receive and guide the lower fingers 38 on the arms 32, 34 as the stops travel to the attaching station. The upper fingers 35 on said arms at the same time embrace opposite sides of the forward chute gravitationally delivered from the chute to the bed and travelling along the bed to the anvil will be maintained in proper position throughout their transfer to the attaching station. This arrangement does away with the use of control pins for holding end stops in their desired position during transfer and also eliminates the necessity of disengaging the con rol pins from the stops immediately prior or subsequent to attachment of said stops.
Means is provided to push the end stops from the delivery end of the chute forwardly to the attaching station at the anvil. Such means comprises a pusher late 58 in the form of a long slender metal strip which is thin enough to enter snugly into the space between the bottom ends of the chute plates 22, 24 and the upper surface of the bed Mi. The back end of said plate is supported in a central slot as of a stepped plunger 62 which is slidable in a bore 64 formed in the forward end of a drive bar 6b. The drive bar is slidably mounted in a journal 68 supported on the base of the machine, said bar being so positioned that the pusher plate is located in the space between the lower end of the chute and the a shaft, the shaft being actuated from a suitable source of power through a one-revolution clutch controlled by a treadle or the like, so that each time the treadle is depressed the bar will reciprocate through one cycle and thereafter remain idle until the treadle has been released and again depressed.
The die 59 also is actuated by the drive bar. For this purpose said die is provided with an upwardly extending shank M terminating in a tappet head 16. compression spring 18 encircling the shank M and lying between the head it and journal 52. The tappet is engaged by the hammer head 86 of a ram screw 82 adjustably threaded into'the front end 84 of a rocker arm 86. Said screw after adjustment to proper operative position is locked in place by a set screw'88. The rocker arm 85 is horizontally pivoted on the block 42 by a thick pin 9!! and the front end of said arm is offset as best seen in Figs. 2 and 3, in order to enable the ram screw to strike the center of the tappet head when the rocker arm is oscillated.
The rear end of the rocker arm rotatacly supports a follower roller 92 which, when the die 55 is in its uppermost position, is disposed to lie in the path of travel of the forward end of the drive bar 86. This end of the drive bar is fashioned with a rounded nose 94 which, as the bar reciprocates, will engage and lift said roller and thus start downward movement of the die Immediately in back of the rounded nose, the drive bar constitutes a hat cam surface 9t parallel to the axis of the bar so that when the roller rides on this surface, the surface acts as a dwell and maintains the die so in a partially depressed position (see Fig. 6). The fiat cam surface 96 is so positioned, having in mind the sizes and relationships of the rocker arm, die and anvil, that when the roller 92 engages said surface, the tip 98 of the die is spaced from the bottom of the The die is urged upwardly by a slot 56 by a distance just proper to snugly accommodate an end stop in the position in which it is fed to the attaching station.
In back of the dwell 95, the cam surface includes a rise 98 which runs into a second flat or dwell I86. Thus, when the drive bar moves further forwardly, the die 50 after being momentarily halted in its downward descent will continue to move toward the anvil 4B and, after it has reached its lowest position (see Fig. '7), will halt momentarily before starting upward.
The length of the pusher plate 58 and the position and stroke of the drive bar is such that, when the roller engages the nose 94, the pusher bar has not yet transferred the lowermost end stop to the attaching station, although at such time the transfer may have begun as indicated at Fig. 1. When the roller is on the dwell 9B, the pusher plate will have delivered the end stop at the attaching station. The tip 98' of the die is formed with a rearwardly facing step [04 so that when the tip is in its position corresponding to engagement of the roller 92 and dwell 9B, the step constitutes a shoulder aligned with the forward edge of the slot 56. Said shoulder and edge act as abutment members to determine the location of an end stop at the attaching station. This position is indicated in Fig. 6.
The plunger 62 is urged forwardly by a compression spring 102 in the bore 64 so that after the end stop to be attached is abutted against the tip of the die and the forward edge of the anvil slot, the pusher plate can advance no farther although this does not prevent further forward movement of the drive bar.
The position indicated in Fig. 6, that is to say when an end stop is pressed against the tip of the dieand the edge of the anvil slot and when the roller is on the forward dwell 96, is the stopping (or starting) point of the operative cycle, that is tosay, the point at which the one-revolution clutch brings the apparatus to a halt. It will be appreciated that when an end stop is in this position, the head of the slide fastener tape readily can be inserted by an operator between the outstretched fingers 36, 38. Then, upon subsequent actuation of the machine, the drive bar will continue its forward travel so that the riser 98 engages the roller and further depresses the die. As the die descends, it will urge together the fingers 36, 38 of each of the arms as indicated in Fig. 7. After the end stop has been attached as indicated in Fig. 8, the machine continues its, cycle, the drive bar retracts to the position of Fig. 8 wherein the tip of the pusher plate is in back of the deliver end of the gravity chute so as to allow the lowermost stop to drop out of the chute. Then the bar advances to the position shown in Fig. l to push the lowermost end stop toward the attaching station and finally the punch descends to its intermediate position and the plate presses the end stop against the punch as shown in Fig. 7 whereupon the machine stops. It may be mentioned that, when the die rises, the tape with attached stop is withdrawn.
It thus will be seen that I have provided a device which achieves the several objects of my invention and is well adapted to meet the conditions of practical use.
As various possible embodiments may be made of the above invention, and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein described is to be interpreted as illustrative and not in a limiting sense. I Having thus described my invention, I claim as new and desire to secure by Letters Patent:
