Thisjgiw maximum holdingpower he pegs sary -n order to insure that the pegs do not pull out of the insole. As a shoe ready forv the operation ofi a bed` lastingmachine is mounted' upon last7V its bottom cannot-be calf reu', as might be done il it were cti the `East. Until the present invention there Was no mechanism l'rnoivn to me which col` d be utilized to measure the thickness or ashoe bot-tom While the shoe was on'the last thereby to control' the length oi the fastenings inserted.

it is an object of i present invention to provide fastening inserting' mechanism having` means ior measuring the thickness oi*- the and means'lior inserting in the bottom of the shoe '.eninfgs the lengths of `which correspond to 'the measured' thickness 'of the shoe bottom.

l-ir accordance with this object and with Jsature of the invention, the illustrated machine is provided With an `aWl and 'op erating'` means therefor of such nature that' the aivl can be driven through the nottom of shoe mounted upon a last and arrested bv striking;- a metal plate noon the bottoni oie thelasthwithout interfering with the nor mal operation of the machine and Without danger-of hreal'ing the aiv-l or eperatingg mechanisml f- Thus the lengt-h of the stroke of the a-Wl isdependent upon the thickness Y Serial No.

M CHENE of the stocl; which thel aWl penetrates and the length of the aWl stroke is utilizedi tol control the length of the fastenings inserted in the holes formed by theV aiwl;`

In accordance with another featured the vinvention the awl operating means of the illustrated machine includes an awl barror carrier, and a connection between thel a-Wl hat and means for reciprocating theV awl bar which `connection is broken When4 the 'aWl meets an excessive resistance duringl its Work? penetratingstroke but which is remade later in the' cycle oi operation so thatthe aivl bar is picked up and the awl is withdrawn from the shoebottom. .Th-us the cycle of'operaticn of the machine is completed as it would have been if the stock into which the avv-l was thrust was thick enough so that thea-Wl did not pass entirely througlr it and the machine is ready tol operate through another" cycle. The fastenings inserted byl the' illiislirate machine are severed from a` strip' of' fase teni'ng materiakq `for example paper-twine; commonly called liber-fastening' 'materii'rll,Y which is fedi intermittently by mechanism controlled by the movement or' the avrili bar soV that eachfastening severed from the strip is of a-length determined by tliedi'stancevwhich the a-Wl penetrates the Work beforeit driver operating mechanism comprising a=v continuously reciprocating member, a diiver operating member, and connections between the two members arranged to be madeiand broken by a' manually operabl'econtrollr so that` the driver operating' member can be" driven intermittently, at thevvill of theoper'- ator, lby the continuously reciprocating member. This constructionfreduces toafminimum the Weight of the parts which must bese iiil motion and stopped eachtime-thaothe fas#V tening inserting means is started and stopped.

lVhile the invention is illustrated herein as embodied in a fastening inserting machine intended to take the place of the hand tackers commonly used with bed lasting machines, it is clear that the invention is not limited in its utility to embodiment in iastening inserting machines of that type and, accordingly, the construction disclosed herein should be regarded primarily as an illustrationof one or the forms in which my invention may be embodied.

With the above and other objects and teatures in view the invention will now be described with reference to the accompanying drawings and pointed out in the claims.

In thedrawings,

Fig. 1 is a side elevation, partly in section., of a fastening inserting machine'embodying the invention;

Fig. 2 is a similar view of the fastening instrumentalities of the machine, on larger scale, showing the parts in the position which they occupy at the conclusion of the punching of a fastening receiving hole in the work rpleCe;

v Fig.4 3 is a view similar to Fig'. 2, showing the position ot the parts at the end ot the feeding oj the strip of fastening material preparatory to the severing of a fastening therefrom; Y

Figs. 4 andV 5 show the position of 'the parts at the beginning and at the end respectively ot the driving of a fastening; and

-Figs `6 and 7 illustrate connections by means of which the length of the punching or awl stroke and the length of the fastening severed from the stripvr, are controlled in accordance .with the thickness oi*I the shoe parts through which the asteningis to be driven. The illustrated fastening inserting machine is intended to take the place of the hand tackers commonly usedY in lasting the toes oli' .McKay shoes and the heel portions ol' Goodyear welt, McKay and other types ol shoes. In order to avoid the objections incidental to the use of tacks to securefshoe uppers inlastedposition, the illustrated machine, is 'arranged to rinsert libre pegs orP the char-` acter ,disclosed in Letters Patent or the United States No. 1,7 29,169 granted September 24, 1929, on an application tiled in the name o Fred N. LaChapelle. severed from a strip or" fibre peg material such as paper twine and inserted in holes punched by the machine through the shoe upper into the insole. Y

The fastening-inserting instrumentalities ot themachine are carried at the end of an arm 10 counterbalanced by a weight W and pivoted at12, for vertical swinging movement, to a bracket 14 mounted lor horizontal swinging movementv at the top `of a column 16 so that the fastening-inserting instrumen-A These pegs are talities can readily be presented to the different parts of a shoe to secure the toe and heel portions oiz the shoe upper in lasted relation to the insole and last. rlhe column 16, which carries also a reel 18 containing a supply of the peg material 19, may conveniently be secured 'to a bed lasting machine. The bracket 14 carries also a motor 20 geared, as shown at 22, to a cam member 24 provided with a pair or' cam tracks 26, 28. In these cam tracks are positioned a pair of rolls 80, 32 carried respectively by slide blocks mounted for longitudinal sliding movement in ways formed in the arm 10 and pivoted at 34, 86 respectively vto longitudinally movable rods 88, 40 extending lengthwise of the arm 10 and pivoted respectively at their right-hand ends to a pair ot bell crank levers 42, 44 ulcrumed at 46, 48 to an arm 50 carried by the right-hand end the arm 10 and serving to operate the fastening-inserting ins'trumentalities. The bell crank lever 44 is rocked twiceA and the lever 42 once during each revolution of the cam member 24.

Depending from the lower end of the arm 50 is a tube 52 carrying at its lower end a housing 54 which contains the fastening severing and inserting portions of the machine. Within the tube 52 is a sleeve 56 utilized to operate the fastening severing means and carrying at its upper end a collar 57 provided with a pair of slots which receive pins 58 carried by the bifurcated end of the bell crank lever so that rocking' of the bell crank lever about its ulcrum 46 will reciprocate the sleeve 56. WTithin the sleeve 56 is a rod 60 carrying a tool 104 which acts both as an awl and as a driver. To the upper end 0In the rod 60 is clamped a collar 62 to which is pivoted a depending lat-ch member 64 urged in a clockwise direction, as viewed in the variousk figures of the drawings, by a spring 66. The latch member 64 is provided with an approximately horizontal shoulder 68 (Figs. 1 and 6) engaging a complemental shoulder 70 formed upon a shorter latch member 72 pivoted at 7 4 to a sleeve 7 6 surrounding the rod 60 and forming a guide for the upper end of the rod. lThe sleeve 76 is provided with a pair of horizontal slots entered by a pair of pins 'l' 8 carried by the bifurcated end of the bell. crank lever 44.

Then the motor 2O is running the bell crank levers 42 and 44 are continuously oscillated. but when the machine is not in use the sleeve 76 slides idly up and down on the rod 60 and the fastening-inserting instrumentalities are inoperative since the latch 64 is held disengaged from the latch 72, as shown in Fig. 1. To hold the latch members 64 and 72 disengaged while the machine is not iny operation the latch member 64 is provided with a linger 80 extending toward the leftl and engaged by a latch member 82 having the 'torni of a bell crank lever fulcrumed at 84 to Aan extension 86 ofthe arm 50. The latch Yto hold the latch 82 in the position shown 1n Fig. 1, under which circumstances the shoulT ders 68, of the latch members 64, 72 are disengaged. A pin 1.02, extending through the extension 86, limits the movement in a clockwise direction of the latch member 82. lffheu the operator squeezes the trigger 94, as illustrated in Fig. 2, the latch member 82 1s moved in a counterclockwise direction, as indicated in dotted lines in Fig. 3, releasing the linger of the latch member 64 so that the latter is rotated by its spr-ing 66 to bring-its shoulder 68 into such position that when the latch member 70 reaches the upper end of its reciprocating movement the shoulder 68 can `)ass beneath the shoulder 70 of the latch member 72, latching the two together. Subsequent downward movementk of `the sleeve 76 is thus operative to move the rod V60 downwardly, as shown in Fign2.

The rod 60 .serves as a carrier for the tool 104 which is reciprocated through aV throat or nozzle 105, acting both as an awl and as a driver, and which, as a matter of convenience,

is hereinafter spoken of either'as an awl oras a driver. according to the function Yunder consideration. 1n the tool 104 v1s shown acting as an awl tol punch a hole through the various layers 106 of a rshoe upper and .insole mounted upon va last 108`provi ded with a metal bottom plat-'efor heel plate 110; When the awl 104 hits the metal Yplate 110 the excessive resistance arrests the rod 60 and it can no longer move downwardly. 'l` iis takes place before the completion of the first downward movementl of the outwardly extending arm of the hell crank lever 44 in each cycle of operation of the machine.v

Thereafter the continued movement of the bell crank lever 44. which, it is to be remembered. is connected by pin-and-slot connection to the sleeve 7 6, is effective to rock the latch member 72 about its pivot 74 in a counterclock-.wise direction against'the compression of-a spring 112 surrounding a pin-114 carried by the sleeve 7 6 and bearing atone end against the 'lowerend of the latch member 72 and at the other end against a nut 116 threaded on the pin 114. AAs the lower end of the latch member 2 engages the lower end off the long er latch member 64, this rocking movement of the1latchme1nber72 iseflectlvealso to rock` the latch member 64 against its spring 66,

pushing or dragging the shoulder 68 out fromV nunder the' shoulder `TO'a-nd thusbreaking the driving connection to the awl 104, after vwhich the latch member 7 2 and the sleeve 76 `areffree to continue Vtheir downwardV move- "lfhus, the work penetrating movement of the awl 104 is effective to measure the thickness of the shoe bottom thrust.

The extent of this movement of the awlV 1 04 is utilized to .measure the length of the fastening severed from the Vstrip 19 of fastening material, for example paper twine, carried by the reel 18.` The strip 19 passes through a vertical guide tube 122 extending upwardly at the right-hand end of a block 124 clamped to the lower end of the tube 56. Below .the tube 122 the guide block 124 is provided with a depending portion having a surface 126 (Fig. 3) past which the strip 19 passes. Opposed to the'surface 126 is a dog 128 also arranged to bear against the strip 19 and pivoted to the Vend of a bell crank lever 130 which is fulcrumed at 132 to the depending portion of the block 124. The bell crank lever 130 is urged in a counterclockwise direction by a spring 134 and its upwardly lextending arm carriesa projection 136 (Fig. 2) bearingagainst the rod 60 and arranged to entera groove-138 formed in the rod 60 just before the conclusion of the down stroke of the rod. The distance from the projection 136 tothe lowerend'of the groove 138 at the conclusion of the work-penetrating movement .of the' awl 104 will, of course, depend upon the thickness of the stock between the nozzle 105 and the metal plate 110 of the last. The feeding of the strip of fastening material is caused by sliding the block 124 downwardly along the rod v60 while the latter is held stationary at the termination of the work-penetrating movement of the awl 104, the strip 19 being gripped betweenthe dog 128 and the surface 126 asthe block 124 is moved downwardly until the projection 136 reaches the lowerv end `of the groove 138;

When this takes place, further downward movement of; thefblock 124 causes the lower end .of the groove 138 to cam the projection 1360i the lever 130 to the right, rocking the lever 130 in a clockwise direction, as viewed in the various figures, and thus relieving the pressure of the dog 128 on thestrip 120 and terminating the feeding of the strip. VThe block 124 is'giveu this ldownward movement by the cam 24, the motion being transmitted Y by the rod 38, the bell crank lever 42 and the sleeve 56.

parts into which, it is To prevent retrograde movementl of the strip 19, the latter passes beneath a. second dog 140 pivoted to the end of a lever 142 fulcrumed at 144 to the housing54. A springr 146 tends to rock the lever 142 in a counterclockwise direction, thus gripping the strip between the dog` 140 and a stationary surface 148. Feeding movement of the strip 19 rocks lever 142 slightly against the action of the spring 146, relieving the pressure of the dog` 140 on the strip. Y Retrograde movement of the strip 19 has the opposite effect and any tendencythereto results in gripping the strip firmly between the dog 140 and the surface 148.

From the dog 140 the strip 19 of fastening material Vpasses through a stationary tube 150 the lower end of which is supported by a stationary block 152 carried near the lower end of the housing 54. The severing of pegs from the'strip 19 of fastening material is accomplished by rocking.movement of bell crank lever 156 fulcrumed upon a stationary pin 158 extending transversely through thehousing 54 and provided with a passage 160 (Fig. 3) through which the tool 104 may pass. The bell crank lever 156 is provided with a passage 162 .which at the time of the feeding of the fastening is in alinement with the tube 150 and also with a second passage which is in alinement with the tool 104 at all times when the lower end of the latter is closely adjacent to or below the intersection of its path of movement with the upper snrface of the bell crank lever 156. VThe metal at the inlet end of the passa-ge 162'and at the outlet of the hole inthe block 152, which hole serves as a continuation ofthe tube 150, serve to shear a pcg from the strip 19 as the bell crank lever 156 is rocked.

After the fastening'material has been fed, the rod 60 is moved upwardly, withdrawing the awl 104 to a position above the bell crank lever 156. rEhe bell crank ever 156 is then rocked in a counterclockwise direction from the position shown in Fig. 1 to the position shown in Fig. 4, thus severing a fastening and bringing it into posit-ion to be driven. This is accomplished by further downward move- Y ment of the sleeve 56 which brings the block 124 into engagement with a collar 170 secured to arod 12/'2 the npper end of which is lguided by the block 124 and the lower end by the block 152.y At its lower end the rod 1'? 2 is pivoted to the bell. crank lever 156. A

compression spring 176 engages at its upper enn against'v the collar 170 and at its lower end against thel block 152. thus serving to maintain thebell crank lever 156 in the position shown in Figs. 1. and 8 except when `is carried by the housing 54 at the righthand end of the path of movement of the .upper end of the bell crank lever 156.

bers 64, 72 have no tendency to disengage f since the form of the cam groove 28 is such that the sleeve 76 is not moved downwardly after the driver 104 comes to rest.

After return movement of the rod 60 at the conclusion of the driver stroke, the machine will start upon a new cycle of operation if pressure is maintained upon the trigger 94. If, however, the trigger 94 is released before the conclusion of the cycle, the latch member 82 will move into position to engage the finger 80 of the latch member 64 just before the conclusion of the upward stroke of the rod 60 and will cause the latch member 64 to swing to the position shown in Fig. 'l in which it is released from the latch member 72 so that the machine will cease to operate.

Then operating the illustrated machine the operator grasps it by the handle 98, bringing the nozzle 105'into position on the shoe bottom or other work piece into which a fastening is to be inserted, and then presses the trigger 94 to cause the operation of the device. The movement of the trigger is effective through the connection 90 to swing the latch 82 from the position shown in Fig. 1 to the position shown in Fig. 2, thus releasing the finger 80. and permitting the latch member 64 to move into the position shown in Fig. 2 in which its shoulder 68 engages beneath the shoulder 70 of the latch member 72. Vhen this takes place the sleeve 76, which is reciprocated continuouslyby the Vmotion transmitted from the motor 20 through the cam 28, the rod and the bell crank lever 44, causes therod to move downwardly thus thrusting the awl 104 forcibly into the work piece. TvVhen the end of the awl strikes the metal bottom plate 110 of the last 108 the awl can pass no further. Continued downward movement of the sleeve 76 is then effective to rock the latch members 72 and 64 in the manner shown in Fig. 6, thus releasing the shoulder 68of the latch member 64 from the shoulder of the latchmember 72 so that the sleeve 76 can continue its downward movement. Upon subsequent upward movement of the sleeve 76 its upper-.end engages the collar 62 which is clamped to the rod 60 and lifts the latter, withdrawing the awl from the work piece. Subsequent to the downward movement of the rod 60 the block 124 and the bell crank lever 130 are moved downwardly by the sleeve 56, feedingthe fastening material 19 downwardly7 till the projection 136 of the bell crank 130 reaches the lower vend of the slot 138.

The length of the fastening subsequently severed is determined by the extent of movement of the sleeve 56 and the bell crank Alever 130 before the projection 136 of the belll crank. lever 15h is cammed to the right by the'lower end of the groove 188 formed on the rod `60 and the feed dog 128 is rendered inoperative'. Thus the length of the fastening is (leien mi ned by the thickness of the work piece into which it is to be inserted. il second downfy ward movement of the rod 60 is effectivev to cause the tool eL to drive the fastening through 'the nozzle 105 into the workpiece.

This action is continued cyclicallyv as long as the tr' gger Sil ispressed toward the handle 98. V'Then the trigger is released themacliine completes the cycle of operation upon which it isengaged and at the end ofthe cycle the linger 80 is rocked in a counterclockwise di rection by engagement with the end of the latch member 82, thus withdrawing the shoulder 68 of the latch member 64 from the shoul f der "ZO of the latch member 72 and causing the rod 60 to comeV to rest.
