FASTENING-INSERTING LIACHINTE.

Application fi1ed J'une 7, 1916. Serial No. 102,291.

1 0 all whom it may concern Be it known that I, LOUIS A. CASGRAIN, a citizen of the United States, residing at Beverly, in the county of Essex and State of the invention, the wire feeding mechanism is rendered operative at such predetermined times only in the cycle of operations of Massachusetts, have invented certain Improvements in Fastening- Inserting -Machines, of which the following description, in connectionwiththe accompanying drawings, is a specification, like reference charac- 10 ters onthe drawings indicating likeparts in the several figures.

This invention relates to machines for inserting fastenings, and more particularly to machines'for inserting screw threaded fas- 15. tenings into the soles of boots and shoes. The invention is herein shown by way of illustration as embodied in a screw threaded fastening inserting machine of the type dis-- closed in United States Letters Patent No. 490,621, granted January 24,1893, on an application of Louis Goddu.

Fastening inserting machines of the type illustrated in said Letters Patent comprise a wire carrying spindle arranged to rotate continuously at comparatively high speed, and two lateral shafts having connections with the wire carrying spindle by which they are continuously driven, one of said shafts carrying the cams through which the wire feeding, wire severing, and horn releasing mechanisms are operated. For suspending the operation of the wire feeding mechanism to stop the insertion of fastenings, machines of this type are-providedwith manually op- 85 erated means arranged to disconnect the wire feeding mechanism from its operating cam. Considerable difliculty, however, is encountered in operating machines in which the wire feeding mechanism is so controlled due 40 to the liability of an operator initiating the operation of the wire feedingmechanism at such a time in the machine cycle that it will not impart a complete initial feeding movement to the wire feeding mechanism for feeding the wire into position to form the firstfl fastening, and frequentlythe first fastening is shorter than the length required for the given thickness of stoc i 7 One of the objects of the present invention is to provide improved mechanism for controlling the' operation of the wire feeding mechanism, whereby the'full lengthof wire as required for the thickness ofwork oper- Specification of Letters I atent.

ated upon will alwaysbe fed by the wire feeding mechanism; to insert the first fastening'in the work.

In the illustrated preferred embodiment of the machine as will cause the next operative movement of its operating cam to impart a full wire feeding stroke according to thethickness of the work being operated upon. Preferably, too, and as shown, the wire feeding mechanism is controlled through mechanism controlling the wire severing and horn releasing-mechanisms and, since these mechanisms are interdependent, the proper sequence of operations essential to the efficiency of the ma'chine'is insured.

A further disadvantage resulting from the construction of machines of this type as heretofore designed is that the wire severing and horn releasing mechanisms are maintained continuously in operation even when the machine is not operating to insert fastenings. This causes unnecessary wear of the parts and vibration of the machine. Also, the wire severing cutters become dulled by striking together when they are not operating 'to sever wire.

71th this 111 vlew, the present invention aims also to provide improved mechanism 7 for controlling thewire severing and horn releasing mechanisms, whereby the operation of said mechanisms issuspended when the machine is not operating to insert fastenings. V

In accordance with this object, the preferred. embodiment of the invention comed, the controlling mechanism operating also, as above stated, to control the wire feeding mechanism in'timed relation to the other mechanisms. 7

As Iherein shown, theacontrolling mechait is actuated, it 7 operates to suspend the'opnism is so arranged that, regardless of when I i erationiof'the saidmechani'sms at such pre-.-

determined times only in the cycle of operations of the machine as will insure invariably complete performance of the functions of these mechanisms, whereby the complerangement of the controlling mechanism forthe wire severing, horn releasing, and fastening inserting mechanisms relative to the support for the work of a character to insure the maintenance of the work support in operative position until the completion of the final fastening inserting operation.

Other objects and features of the invention will be apparent when the following description is read, in connection with the accompanying drawings and the novel features of the invention are set forth in the appended claims.

Referring to the drawings,

The machine in which a preferred form of the invention is shown as embodied is substantially like that disclosed in the Letters Patent above mentioned except as herein fully described in detail and to this patent reference may be had for a more detailed description of parts herein illustrated but not fully described.

The illustrated machine is adapted to insert screw threaded wire into work supported on a horn 2, the wire being carried by a reel 4 mounted upon the upper end of a vertically disposed wire carrying spindle 6 mounted for rotation in bearings in the machine frame. The spindle 6 is continuously rotated at comparatively high speed by a belt Spassing over a pulley 10 on the spindle and over an idler 12 to a (:lriving pulley in the base of the machine, the driving pulley 14 being arranged to be clutched to a power driven pulley 16 by a clutch operated through a wedge 18 connected to an operating treadle 20 in the base of the machine. The wire carrying spindle 6 is provided with a worm (not shown) which meshes with worm gears 22 "on the forward ends of two

horizontalv lateral shafts

24 and 26, respectively, which are disposed on either side of the spindle 6 and have other gears 28- and 30, respectively, on their rear ends'to compensate for the rearward thrust of the shafts caused by the worm and gear connection with the spindle 6. The shaft 26 carries the various cams by which the feeding and severing of the wire and the feeding of the work are effected and by which the release of the horn 2 to permit feeding of the work is controlled. The various operating cams are preferably formed so as to cause two operations of the several mechanisms during a single rotation of the cam shaft.

The wire feeding mechanism comprises a wire feed lever 34 (Fig. 4), pivoted at 36 on the frame and having two forwardly extending arms 38, the outer end of each arm 38 being provided with a segmental gear 39 which engages a cooperating rack on a yoke 40 formed on asleeve which is slidably and rotatably mounted on the spin dle 6. The lever 34 has an upwardly extending arm 42 carrying a cam roll 44 which is adapted to be engaged by an edge face 45 onthe wire feeding cam 46 to oscillate the feed lever 34 and, through the rack and gear connections with the sleeve, cause it to move downwardly to insert the wire into the stock, the lower end of the sleeve being provided with wire gripping devices 48 Y which grip the wire and draw it from the reel upon the downward movement of the sleeve. Yielding means (not shown) substantially of the construction illustrated in the above-mentioned Letters Patent are provided to keep the cam roll 44 normally in engagement with the edge face 45 of the cam 46.

The operation of the wire severing cutters 65'to sever the wire after a proper length of wire has been inserted in the work is effected by a cam 62 carried by the shaft 26. This cam is provided with tappets 63 adapted to engage one end of a lever (not shown) the other end of which lever is arranged to oscillate a horizontal shaft on thcouter end of which means for operating the wire cutters 65 is mounted, the construction and operation of the cutters being more fully shown and described in said above mentioned patent. The feeding of the work between each two fastening inserting operations is effected by a feed wheel 6Ov operated from a cam groove 52 formed in the side Y of t'hcca1n46 and connectedthrough-levers feed wheel 60.

The horn 2' for supporting the work is maintained.normally in position to clamp the work against anabutment 3 during the and 56 and a horizontal shaft 58 to the fastening inserting operation by compara- V tively strong spring To. permit the werkto be fed between successive inserting operations, the horn 2 is periodically depressed against the tension of the spring 66 by horn releasing mechanism comprising a lever 68 provided with a cam roll'which engages a cam groove 70 in the side of the wire severing cam 62 and having a link connection 72 to a pawl carrying slide 74 forming part of an automatic horn release and work thickness compensating means which is substantially like that shown and described in United States Letters Patent No. 383,455, granted May 29, 18-88, on an application of Louis Goddu. The cooperating slide 76 of the horn releasing means is connected by a rod 78 and

toggle

80, 82 to one end of a lever 84 fulcrumed at 86 in the base, the other endof the lever being connected by a. rod 88 to the horn supporting shaft 90, the

toggle

80, 82 being provided in order to enable the horn to be finally depressed to a greater extent than is effected by the automatic horn releasing means. The link 82 of this toggle has a pivotal connection with the end of a link 92, the pivotal stud 94 being received in slots in a casing attached to the rod 78. The forward end of the link 92 is provided with a slot which receives a stud 93 on a. tail piece 96 on a, lever 98 pivoted at 100 in the base of the machine. The slot in the link 92 permits lost motion when the treadle 98 is released to prevent a premature loweringof the horn before the fastening is completely inserted.

In accordance with the present invention, the wire severing and horn releasing mechanisms are normally maintained inoperative when the machine is not operating to insert 'fastenings, thereby eliminating unnecessary vibration of the machine and reducing the wear of the parts. Also, said mechanisms are rendered operative at predetermined times when it is desired to insert fastenings.

The illustrated means for controlling the operation of these mechanisms comprises a clutch mechanism constructed and arranged to connect the wire severing and horn releasing cam 62 with its actuating shaft 26 automatically at such times as will insure a complete operation of the wire severing and horn releasing mechanisms and to disconnect the canr62 from its operating shaft at predetermined times only when the insertion of the fastenings is suspended. This clutch mechanism comprises asleeve 102 (Fig. 6) rigidly secured by. a pin 104 to the rear end of the shaft 26 and having secured thereto by bolts'106 the. gear 30 which meshes with tthe gear 28 on the shaft 24.

The sleeve 102 is provided with two longitudinally extending

recesses

108 and 110 located on opposite'sides of the sleeve and adapted to receive plungers'109 and 111, respectively, which are normally pressed outwardly by

springs

112 and 114, respec-I tively. The outer ends of the plungers 109 111 project through the rear end of the sleeve 102 and are secured to a collar 120 slidingly mounted upon the sleeve 102 and having a peripheral groove 122. The plungers are normally held withdrawn from the

sockets

116 and 118 in the cam 6-2 by a yoke member 124 (Figs. 2 and 3) which is pivotally mounted upon a vertically disposed shaft 126 and has two

arms

128 and 130, the upper arm 128'extending above and at right angles to the shaft 26 and the lower arm 180 extending parallel to the arm 128- and below the shaft 26. Intermediate between the ends of the

arms

128 and 130 are rolls 1'32 and 134 mounted on

studs

136 and 138 carried respectively on the

arms

128, 130, these rolls being arranged to travel in the groove 122 in the collar 120. The arms 128 and 130' intersect at their outer ends and carry a hardened steel plate 140 having a beveled surface 142 which engages a similarly beveled surface on the end of a lever or latch 144 pivoted at 146on the machine frame. A spring pressed plunger 148 located in a recess in a lug on the frame has its outer end engaging an offset portion of the lever 144 to maintain the lever normally in engagement with the outer end of the yoke 124. An arm 150 pivoted on a stud 152 on the end of the said yoke carries at its forward end a camroll 154 and at its rear end is loosely connected to the forward end of a rod 156 by an integral collar 158. This end of the rod 156 carries an adjustable spring casing 160 which receives a spring 162 bearing against the collar 158 of the arm 150 and tending to maintain the said arm against an adjustable stop 164 on the rod 156. The opposite end of the rod 156 is pivotally connected by a stud 166 to one arm 168 of a bell-crank lever rigidly 'on the rod 174 acts normally to maintain the clutch mechanism inoperative or in the position illustrated in'Fig. 3, in which position the end of'the lever 144 is in engage- "ment withthe end of the yoke 124 thereby holding the

plungers

109 and 111 out oflthe coeperating sockets in the cam 62. Depression'of the treadle 98 causes the arm 150'to be turnedabout its pivot 152 into position for the cam roll 154 carried on the forward end of the arm to engage a beveled face 179 on the lever 144 and move the outer end of th lever out of engagement with the end of the yoke- 124 to release it whereupon the

springs

112, 114 of the clutch mechanism immediately move the

plungers

109, 111 into clutching or operative relation to the wire severing cam 62.

In order that the cam 62 may be positively and automatically disconnected from its operating shaft 26 at a predetermined point in the cycle of operations of the machine, a face cam 180 is adjustably secured to the rear face of the gear wheel 28 fast on the shaft 24 by bolts 181 which project through slots 183. The acting edge face 182 of this cam is adapted to engage the cam roll 154 on the arm 150 when said arm is in the posi tion it assumes upon the release of the treadle 98. The acting edge face 182 is so formed that .when it engages the cam roll 154 of the lever 150, it first rocks the lever about its pivot into position to compress the spring 162, or to the right, Fig. 3, and then moves the lever longitudinally which causes the outer end of the yoke 124 to be moved rearwardly and the plungers to be withdrawn from the

sockets

116 and 118 in the wire sev ering and horn releasing cam 62. After the cam 180 has imparted its full throw to the lever 150 which moves the yoke 124 into position to be engaged by the arm 144 and held in inoperative position the compressed spring 162 immediately acts upon the rear end of the lever 150 to move its forward end to the left, Fig. 3, clear of engagement with the cam 180. The cam 180 is so timed with relation to the other parts of the machine that the cam 62 is always disconnected from the shaft 26 immediately after the length of wire just inserted into the stock has been severed.

The cam 62 is prevented from further rotation by its momentum after it has been disconnected from its actuating shaft 26 by a braking mechanism comprising a rod 184 ex tending parallel to the

shafts

24, 26 and supported for limited longitudinal sliding movement in a hub provided on the lower arm 130 of the yoke 124. The forward end of the rod 184 is connected at 185 to one end of a lever 186 fulcrumed at 187 on the frame and having its other end in engagement with a friction plug 188 received in a recess in the frame and having its forward end engaging the rear surface of the cam 62. The rod 184 is normally influenced to keep the plug 188 in braking engagement with the cam 62 by a spring 190 surrounding the reanwardly projecting portion of the rod and interposed between the arm 130 and adjusting nuts 192 on the rod. The cam 62 is mounted on a bearing 194, Fig. 6, surrounding the shaft suflicient to cause the plug 188 to force the cam against a cooperating brake member 196 engaging the front face of the cam.

Means are provided for automatically initiating the movement of wire feeding mechanism at such times only as will insure the full length of the initial fastening inserted in the work according to the thickness of work upon the horn and also for automatically suspending the operation of the wire feeding mechanism at predetermined times in the cycle of operations of the machine. The illustrated mechanism comprises a lever 198 pivoted on a stud 200 in the frame and having its upper end provided with a socket 202 which receives a block 203 attached to the under side of the end of the yoke 124. The lower end of the lever 198 is pivotally connected at 204 to a horizontal link 205 which carries at its forward end a block 206 supported in the frame of the machine. This block has a vertical slot 208 through which the lower end of a rod 210 projects, the rod being attached at its upper end to an arm 211 of the wire feed lever 34. This rod forms one leg of the work calipering means, the other leg of said means being secured to an arm projecting from the horn shaft 90. The opposed ends of both rods are confined in a sleeve, all as more fully shown and described in United States Letters Patent No. 908,437, granted January 5, 1909, on an application of G. A. Ambler. The lower end of the rod 210 carries an adjustable collar 216 .which is adapted to pass through a portion of the slot 208 in the block 206 when the wire feed lever is in operative relation to its actuating cam 46. i In the normally inoperative or suspended position of the wire feed lever, the collar 216 rests upon a,

supporting ledge 218 formed in the block 206, as shown in Fig. 5.

It will be seen that as the cam 62 is connected to its actuating shaft 26 to render the machine operative to insert fastenings, which connection occurs immediately after a complete cycle of operations of the machine, the movement of the yoke will simultaneously cause the block 206 to be withdrawn from' collar 216 of the rod and thus suspends the 7 operation of the wire feeding mechanism.

In order'to lnsure a complete lnitlal operation of the machine and to prevent a premature lowering of the horn 2 if the operator releases the treadle before-the last fastening has. been completely. inserted, means are provided for locking the horn in operative position until a predetermined proper time in the cycle of operationsofthe machine or until a complete cycle of operations has occurred.

. The means herein shown comprises a bracket 220 depending from the lower arm 130 ofthe yoke 124 andhaving pivotally mounted thereon a stud 225 and pawl, 226 which is normally and yieldingly held in substantially upright position (see Fig. 2) by a spring pressed plunger 228 located in a vertical lug 229 on the bracket 220. The bellcrank lever 168, rigidlysecured to the shaft 170, has a laterally projecting arm 224the forward endof which is normally disposed in substantially the same vertical plane as the pawl 226, as shown in Fig. 7, and has a bottom face adapted to cooperate with a supporting face 230 provided on the end of the pawl 226. Upon depression of the treadle 98 to start the machine, the forward end of the arm 224 is moved upwardly during which movement it engagesthe pawl 226 and moves it out of the way until he end of the arm 224 is above the pawl 226 at which time the pawl,

underthe influence of its spring pressed plunger 228, immediately snaps under the end of the lever 224 and prevents it from dropping back into normal position, should the operator release the treadle, until the clutch has had an opportunity to move, into operative relation to thecam 62. The movement of, the yoke 124 into operative position through the operation of the clutch then carries the pawl 226 from underthe end of the arm 224. Itfwill thus be seen that a complete initial .cycle of the machine is insured upon depression of the treadle 98 regardless of length of time the treadle is held in depressedposition. Projecting into the path of the end of thearm 224 when the yoke 124 is in operative .position is a fiat shelf 222 formed on the side of the bracket 220. When the operator releases the treadle to stop the machine, the end of the arm 224 en- 0 gages the shelf 222 which prevents the treadle from returning to its normal inoperative position. The location of this shelf is such as will allow the treadle to release sufficiently to bring thecam roll 154 of the arm 150 into operative relation to the cam 180. The treadle, however, is prevented from returning to its completely released position so that the

toggle

80, 82 remains straight and the horn 2 is maintained in work clamping position until the fastening is completely inserted. As the yoke 124 is moved rearwardly and the clutch member withdrawn from engagement with the cam 62 which occurs at a predetermined time and after all operations in that cycle have been completed,the shelf 222 is moved from under-the arm 224whereupon the treadle immediately returns to normal position and breaks the

toggle

80, 82 to lower the horn and allow the work to be re.- moved. A treadle 235 fulcrumed on the shaft 86 has its rear end 236 arranged to engage a p rtion of the lever 84 back of its fulcrum to The operation of the machinemay be de- 7 scribed briefly as follows: s

The parts being in the positions shown in Fig. 1, the operator places the shoe or other work upon the horn 2 and then depresses the treadle 98. pressed, the link, 92 is moved rearwardly thus straightening the

toggle

80, 82 and raisingthe horn into work clamping position, the spring 66 being placed under-tension at the same time. The depression of the treadle 98 also rocks the lever 168 clockwise about its pivot 170 and through the rod 156 moves the arm 150 about its pivot 152 into position to engage the arm 144 and release the outer end of the yoke 124. 7 Upon the release of the outer end of the yoke 124, by the arm 144, the clutch, springs 112, 114 move the

plungers

109 and 111 into position in-the

recesses

116, 118 of the wire severing cam 62which also draws the yoke member forwardly, the recesses in the cam 62 being so located that they only receive the plungers immediately after one complete cycle of operations of the machine has occurred. The movement of the yoke 124 forwardly into operative position causes the lever 198 to 'be oscillated about its pivot 200 whereby the lower endof the lever withdraws the block As the treadle 981 is de' H 7 lower the horn 2 beyond the point provided for by the treadle 98.

206 from under the stop 216 of the depending arm of the wire feed lever 34 thus allowing the Wire feed lever to move into engagement with the wire feeding cam 46. Also, as the tread'le 98 is depressed, the arm 224 of the bell-crank lever 168' positions itself upon the top of the spring pressed pa-wl'226 so as to prevent the treadle from returning to its normal inoperativeposition until the clutch springs have had an opportunity to engage the plungers with the wire severing cam 62, thus insuring a complete cycle of. operations of the machine whenever the machine is treadled. The movement of the yoke 124 forwardly upon movement of the clutch mechanism into clutching :position .then causes the spring pressed pawl 226 to be withdrawn from under the end of the arm 224 whereupon the arm drops down on to the shelf 222 on the bracket 220 providing, of course, the operator has removed his foot from the treadle. As long as the treadle 98 remains depressed, the machine will insert a fastening for each half rota tion of the shaft. 26.' When the treadle 98 is released,- the bell-crank 168 is, moved in a counter clockwise direction which returns the arm 150'into position to be engaged by the continuously rotating cam 180 on the shaft 24. The cam face 182 of this cam then engages the roll 154 on the forward end of the arm 150 and moves the yoke 124 rearwardly to withdraw the

plungers

109, 111,

against the tension of the

springs

112, 114,

' out of the recesses in the Wlre severing cam a right, Fig. 3, before acting directly to move the outer end of the yoke rearwardly and this clockwise movement of the forward end of the arm 150 istaken up by the spring 162 which is interposed between the rear end of the arm 150 and the adjustable stop 160' on the rod 156. After the spring 162 has been compressed upon lateral movement of the arm 150 by the cam'182, the cam moves the yoke 124 rearwardly into position where it can be heldby the arm 144. After the cam 182 has imparted the full amount of throw to the yoke, the spring 162 immediately overcomes the-tendency of the cam to keep the forward end of the arm. 150 forced to the right (Fig. 3) and immediately moves the end of the arm 144 to the left (Fig. 3) a distance sufficient to position it out of the way of the cam to prevent any further engagement with the cam. In order that the horn 2 shall not be released before the com-' plete insertion of the final fastening in the work, the lever 224 is held upon the shelf 222 of the bracket until the yoke 124 has been returned to its normal inoperative position, which movement carries the shelf from under the end of the arm 224 and allows the arm 224 to drop the remaining distance, this distance being sufficient to use up the lost motion between the link 92 and its connection with the treadle so as to permit the

toggle

80, 82 to be broken. Further rotation of the wire severing cam 62 by its momentum is prevented by the brake member 188 which is pressed into engagement with the rear face of the wire severing cam 62 by an arm 102 one end of which engages thebrake member 188 and the other end of which is yieldingly connected through a spring'190 to the arm 130 of the yoke, the rearward movement of the yoke causing the arm 102 to fulcrum about its pivot and engage the brake member 188.
