- One end of the knife arm 172 is pivoted to the fixed block 1133 by a pivot pin 174; the other end of the knife arm 172 projects through a suitable slot 176 in the easing front wall 23.
- the knife arm 172 carries a knife blade 175 which projects upwardly to sever the connections between adjacent fastener elements 113 as will be explained more fully hereinafter.
- the free end of the anvil arm 153 carries an adjustable actuating stem 1173 so that clockwise movement of the an '1 arm 153 about its pivot pin 133 will cause operation of acontrol device by the actuating stem 173.
- the control system for operating the mechanisms of the snap fastener attaching machine may be of any suitable type such as electric, electromechanical, hydraulic or pneumatic systems.
- the present embodiment of this invention utilizes a pneumatic control system and only those parts necessary for an understanding of the invention are being described for the sake of brevity.
- a pneumatic source of air pressure is supplied through inlet 203 to a pneumatic relay control, indicated generally at 232. While the system may be initiated automatically as in any other type of automated machinery, it may be also started manually as by a linkage 234 leading to a foot pedal (not shown).
- the relay control 202 is provided with a pair of fittings, having flexible tubes 236 and 233 connected to opposite ends of the air cylinder 34 for actuation thereof.
- a second pair of fittings 213 and 212 from the pneumatic relay 232 are connected to a pneumatic switch 214 which functions as a control device for terminating operation at the end of the cycle.
- This end of cycle relay 2114 has a pivoted operator 216 which is actuated by the stern 1173 on the anvil arm 1153 as it is pivoted clockwise at the end of each cycle.
- the actuating lever 216 may also be operated manually at any time by means of a plate 221, having a ledge 225, which will actuate lever 216.
- Plate 221 is slideably carried between casing sidewalls 30 and bearing plate 220.
- a coil spring 224 is mounted in tension with one end attached to pin 222 and its opposite end attached to retainer 226 intermediately disposed between the ends of a roller bar 223.
- One end of the roller bar 223 is pivotally mounted on plate 221 by means of a pivot pin 233 while its other end carries a roller element 232 which rests in valley 223 of the cam surface in plate 220, which determines the neutral position. Movement is imparted to the plate 221 and the roller 232 by the terminus 234 of a manual lever which has a push-type handle 2316 on its other end extending through the casing front wall 23.
- a complete snap fastener device includes a base element 13 joined to a socket element as the first unit, and a base element 13 joined to a stud element as the second unit. in such an arrangement, the base 113 and the socket 23 form the female unit while the base 13 and the stud form the male unit of the complete fastener device.
- the ready condition of the machine is represented by Fig. 6.
- the cylinder 34 is displaced from the trun nion block 33 and the coil spring 44 on the shaft 36 is compressed.
- the piston shaft 43 extending from the other end of the air cylinder 34 is at its minumum extension whereby the toggle mechanism is in its unactuated condition with the ram 143 located in its uppermost condition.
- the cylinder 34 has not yet been moved so the bar 72 is in engagement with the pin 1132 which retains the lever 134 in its ex treme clockwise position; the upper feed arm 1133 is thus placed in a ready condition.
- a spring ratchet member prevents withdrawal of fastener elements 113 and aids in positioning element 113 in its proper position.
- lever 73 and lever arm 30 The downward movement of bar 72 causes lever 73 and lever arm 30 to likewise move downward in a counterclockwise direction about the pivot 34; such movement continues until lever arm 33 engages the stop member 35 and transfers the pivot screw 73 from an upper to a lower plane relative to the plane of pivot 34.
- the lever 32 is permitted to pivot counterclockwise about the fixed pivot 34 because of the tension spring 33.
- the lower feed arm 33 moves in the channel box 32 causing the grippers 33 to advance the snap fastener strip 23.
- Fig. 9 is similar to Fig. 3 in illustrating an intermediate stage of the operation.
- the toggle links 52 and 66 have not yet reached their full extension and the ram end is only slightly away from performing the clamping operation.
- the pivot movement of the anvil arm 1153 causes the link M3 and the knife arm 172 to move upward whereby the lower knife blade 175 severs the connections between adjacent fastener elements 18.
- This pivotal movement also causes the activator stem 178 to pivot the lever 216 whereby the pneumatic switch 214 ends the cycle and exhausts the air cylinder 34.
- the cylinder 34 then returns to its initial position as shown in Fig. 6. During such return movement the upper and lower feed arms 108 and 90 are retracted and slightly pivoted permitting the sloping edges of the grippers 118 and 98, respectively, to ride over the fastener elements and 18, respectively.
