" re utation filed December 26, 1915:- Serial No. 138,968,

'cerned with machines of this general character designed for use 111 the manufacture of boots and shoes. t

hen it is desired to use machines of this character to insert fastenings accurately with reference to some particular part of the work it is usual toemploy gaging means of some kind adapted to position the Work properly with reference to the'lineiof drive of the fastenings, and thus to insure the cor rect locationvof the fastenings in the work. In some instances the work is of such a character that it is impracticable to gage or guide it in this manner and it then becomes necessary to position the work by hand. Vhile this may be conveniently done if only a rough location of the fastenings in the work is desired, it is a very slow and relatively difiicult proceeding where an extremely accurate positioning of the fasten;- ings is required. Accordingly, it is the gen eral object of the present invention to devise means for facilitating the accurate location of fastenings in the work which can not be conveniently gaged or guided by the usual work positioning means or where for any reason it is preferable to avoid the use of such means.

The invention will be herein disclosed as embodied in a machine designed especially to secure ornaments to shoesor to work of some other descrlption; It 1s" a common practice to. secure a bow,'buckle or other ornament to a pump at the throat of the vamp. Sometimes also a buckle 'or other metallic ornament is first secured to a bow which later is fastened to the pump. These ornaments are usually provided with holes to receive the fasteningsby which. they are to be secured in place, ,or else are so designed that tl1ey 'canbe-secured by staples straddling narrow bars or similar portions of the ornaments. It is here proposed to attain the general objectabove defined by so constructing and organizing the fastening inserting mechanism that it will partially eject the fastening from the throat or nozzle, with which machines of this type usually are equipped, and will maintain the fastening in this position long enough to allow the workman to position the work accurately with reference to it. Preferably the mech- Patented. Nov/11', 1919.

anism is so arranged that the workman controls at will the subsequent driving of the fastening so positioned and he is, therefore, enabled to be absolutely certain that he has the work so positioned with reference to the fastening that it will be inserted in exactly the right place before he allows the machine to drive the fastening.

The particular manner in which it is here.

proposed to solve the problem presented by the condition above described, and the various features of the invention will be readily understood from the following description of the embodiment of the invention now preferred by me, reference being made to the accompanying drawings, in which Figure 1 is an angular view showing a stapling machine constructed in accordance with this invention;

Fig. 2 is a rear elevation partly in section showing the clutch mechanism employed in the machine;

V Fig. 3 is an angular view showing parts of the staple forming mechanism;

Fig. a is a front elevation showing part of the wire" feeding and staple forming and driving mechanism;

Figs. 5, 6 and 7 are side, plan and front views, respectively, of the driver lifting cam and part of the driver bar adjacent thereto, Figs. 5 and 6'being partly 'in cross section; g

F, g. 8 is-an angular view showing the two parts of thenozzle through which the staple I I i Phelan Patent No. 883,824, granted April these features, the machine shown also includes a work support and a clutch construction differing from those shown in the patents above designated.

The staple forming and inserting mechanism includes a split nozzle, the rear half 2 (see Figs. 4 and 8) being secured to the stationary head of the machine and the front half 4 being shaped to constitute a staple former and arranged to cooperate with'an anvil or inside former 5 (see Fi 4) to bend the wire into the form of a staple. The movable nozzle part 4 is grooved to provide a passage 6 for the driver 7. A wire feeding and cutting mechanism advances into a groove 8 (Fig. 8) formed in the rear face of the front nozzle member 4 the proper length of vire V to form a staple, this length of wire lying just above the anvil 5 (as shown in Fig. 4), which at this time is in its forward or advanced position. The nozzle part 4 then is moved downwardly thus bending the wire over the anvil into the form of a staple and leaving the staple positioned in the driver passage 6 at a point just above the groove 8. This completes the staple forming oper ations. v

For the purpose of moving the nozz e piece, or staple former 4, up and down with reference to the anvil 5, this member is secured to a slide 10 (Figs. 1 and 3), which is raised and lowered by connections with a roll running in a cam path 12 formed in a cam 14 mounted fast on the main shaft of the machine. These connections include the block 15 (see Fig. pivoted to one side of the slide 10 and a forked lever 16 which engages said block. A cap plate 18 overlies the slide 10 and holds it in its operative position. The anvil 5 is advanced and retracted by connections with a lever 20 (Fig. 1) which is operated from another cam path formed in the cam 14. These operating mechanisms are substantially like those by which the corresponding parts are operated in the machine shown. in the Phelan patent above designated.

The wire from which the staples are formed is fed to the staple forming mechanism from a reel 21, this wire being led from. the reel through a feed block 22 (Fig. 4) under a presserfoot 24 and through a guide block 26 to the groove Sin the former 4. The feed block22 is reeiprocated back and forth toward and from the former 4 by connections (fully described in the Phelan patent above designated) with a cam 28 on the main shaft of the machine. Obviously any suitable wire feeding mechanism may be used, but for thesake of explaining the departure of the mechanism shown from that disclosed in the Phelan patent, it may be noted that the feed block 22 contains two hardened pieces 30 and 32, respectively, between'which-the wire passes, the lower block 30 being substantially rectangular in shape and the upper block 32 being wedge shaped, and cotiperating with an inclined upper wall of the recess in which it is received. to clamp the wire againstthe block 30 when pressed backwardly by means of a spring 34, one end of which is secured to a pin 35 projecting from the block 32 and the other end to another pin 36 secured to the feed block 22 as clearly shown in Fig. 4.

A finger piece 38, pivoted on the pin 36, is

shaped at its forward end to engage the pin '35, when swung upwardly, and force the block 32 away from the pin 36 thus relieving the pressure of the block 32 on the wire W. i

The movement of the feed block 22 toward the anvil 5 advances the length of wire required for a staple into the groove 8 and the wire is then cut off at the point where it emerges from the guide block 26 by means of a knife or cutter 40 which is moved by a cam operated lever 42. The knife shears off the wire diagonally and thus points the ends of the staple. When the feed block 22 starts on its return stroke away from the staple forming mechanism, the presserfoot 24 is depressed and grips the wire N at a point'just behind the guide block 26, thus preventing the wire from being drawn backwardly by the grip of the parts carried by the feed block 22. Normally the presser. foot 24 merely rests on the wire, but it is forced downwardly while the feeder makes its return stroke by means of a spring pressed plunger 44 (see Fig. 3) which bears on the upper end 45 of the presser foot 24. In order to relieve the .presser foot from the pressure of the spring pressed plunger while the feeding movement of the wire is taking place, the upper end of the plunger has a nut 46 threaded on to it which rests 1 on a short post 48 fixed to a bar 50 that is carried by the vertically movable slide 10. Since the backward movement of. the feed block starts shortly before the upward movement of the former 4 and slide 10 have begun, the connection ust described will relieve the pressure of the part 24 on the wire at the proper point in the cycle of operations of the mechanism.

designated; and the machine is also equipped with the mechanism shown in said patent for adjusting the length of the wire fed to thestaple forming mechanism in each cycle of operations of the machine.

A' staple having been formed and positioned in the path of the driver 7, in the manner above described, and the anvil 5 having withdrawn, the driver 7 is-neXt advanced far enoughto force the staple partly out of the passage 6 in the nozzle and leave it with its legs protruding from the nozzle, as shown'in Figs. 1 and 9, the staple being indicated at S. The tendency of the staple to spread, due to the spring of the wire, causes the legs of the staple to'b ear against the opposite walls of the driver passage 6 with suflicient force to maintain the staple in its partially ejected position.

For the purposes of giving the driver this staple positioning movement, a driver cam 52 of a peculiar construction is mounted on the forward end of the main shaft of the machine. The driver bar is made in two sections 53 and 54, as in the construction shown in Patent No. 883,824 above mentioned, and the cam 52 raises this bar against the tension of a strong spring 56, as in the arrangement shown in said patent, this spring acting as soon as the cam permits it to depress the driver. The cam is rotated in a counter clockwise direction, as indicated by the arrow in Fig. 7, so that after the driver has been fully depressed the forward end of the cam engages the hardened block 58'on the driver bar 54 and raises the driver bar, and consequently the driver, to the upper limit of its stroke. As the trailing end of the cam 52 moves out of engagement with the block 58, this block slides down relatively slowly over the cam surface 59 (see Fig; 7) until the parts reach'the relative positions in which they are shown in Fig. 7 with the block 58 resting on the point 60 of the cam. The clutch mechanism with which the machine is provided stops the machine when the parts have reached this position and the downward stroke of the driver permitted bythis cam construction gives the driver its staple positioning movement. That is, it causes the driver to force the staple down through the nozzle into a position where it protrudes fromthe end of the nozzle.

The cycle of operations of the machine is completed at this time,but at the beginning of the next cycle the further rotation of the cam 52, starting from the position in which it is shownin Fig. 7, causes the point 60 of the cam to raise the driver block- 58, and consequently the driver, and then to move out of engagement with the block 58, whereupon the spring 56 quickly forces the driver downwardly and gives it its staple driving stroke. I

In order to stop the machine at the proper point in its cycle of operations, as just described, a clutch .mechanism is provided which is best shown in Figs.-1 and 2. Power is applied to the machine by a driving belt 1 running on a pulley-62 loose on the main shaft 64. V The clutch shown is of the Horton type and includesa series. of balls 66 the shaft 64 and recessed, asshown in Fig;

2, to receive the balls 66. A cage 68 mounted just in front of the pulley 62 has fingers 69 projecting rearwardly into the spaces between the balls 66 and has a projection 70 designed to engage a stop 7 2' mounted on part. of the machine frame. A spring 74 connects the cage 68 with a collar 67, which rotates with the shaft 64, andtends to turn the cage forward in the direction of rotation of the pulley 62 and thus to move the balls 66 forward into a wedging relationship to the members 67 and 62. The stop 72 normally prevents the spring 74 from acting in this manner and acts through the cage 68 to hold the balls 66 in their inoperative or unclutched positions. As soon, however, as the stop 72 is moved out of'engagementwith the cage projection 70, the spring 74 acts,

in the manner just described, to effect a driv- 111g connection between the loose pulley 62.

and the shaft 64. and thus to cause the shaft to revolve. The stop '72 slides in a bracket 76 which is pivoted on a stud 77 and a spring 78 acts through the bracket to main- :tain the stop 72 normally in the path of movement of the part 7 0. Another spring 7 9 acts on the inner end of the plunger 72 to press it outwardly, but this outward in the part '7 6. In order to swing the stop 72 out of engagement with the cage pro jection 70 a small lever 82 has one arm in engagement-with the part 76 and its other arm is positioned for engagement with a latch 83 pivoted on a rod 84 wl1ich is arranged to slide vertically in the machine frame. The latch is normally held forward toward the lever 82 by a spring 86. The rod 84 is'connected by another rod 88 (see Figs. 2 and 9) to a treadle 89 pivoted to the base of the machine. When this treadle is depressed the latch 83 swings the lever 82in a,

direction which causes it to swing the bracket 7 6 and the stop 72 about the pivot bolt-'7 7 in a clockwise direction, thus moving the stop out of engagement withthe cage projection 70 and allowing the clutch to soon as it has beendepressed far enoughitotrip the clutch to move the-latch out of engagement with the lever 82 and thus permitthe spring 78 to reset the stop 7 2 again in the path of the cage projection 70. The ma chine thus is allowed to make only a single revolution at each depression of the treadle 89.

Obviously any suitable type of single revolution clutch can be used for this purpose and that shown herein has been described merely for the purpose of disclosing a completely operative mechanism.

In order to sustain the work for the driving of the fastenings, a work supporting horn 92 (see Figs. land 9) is provided, this horn being shaped to support a shoe in the proper position for the attachment of ornaments to the throat of the shoe vamp. Obviously the character of the work support used will vary with the nature of the work to be operated upon. The horn 92 is mounted on a slide supported in a bracket 9% and is so connected with a treadle 96, as clearly shown in Fig. 9, that it can be raised or lowered to permitthe presentation of the work to and its removal from the machine. Preferably the treadle 96 is made to overlap the clutch treadle 89 so that when the workman has the work properly positioned on the horn 92 and depresses the treadle 96 he will first raise the work substantially into engagement with the nozzle t and then trip the clutch. Obviously the treadle 89 may be depressed independently of the treadle 96 to cause the fastening forming and driving mechanism to form a fastening and position it at the outlet of the nozzle as shown in Figs. 1 and 9." This operation occasionally becomes necessary when the fastening made and properly positioned in the regular operation of the machine becomes displaced or withdrawn from the nozzle by accidental contact with the work. Furthermore, the treadle 96 may be depressed to such an extent only as to cause the presentation of the work to'the staple in the nozzle. Treadle 96 will then be farther depressed to contact with and depress treadle 89 to cause the operation of the inserting mechanism when it has been decided that the work is properly positioned with respect to the staple.

It will now be understood that the machine is stopped by the clutch mechanism above described when a staple has been made and pushed partly out of the nozzle. The workman then can place the ornament on the shoe, or other article to which it is to be secured, support the work on the horn 92 and present it with great accuracy to the staple which is protruding from the nozzle. He can either bring the legs of the staple into alinement with the holes provided for them in the ornament or he can make the staple straddle a bar or some other narrow portion of the ornament. l/Vhen he has the parts properly positioned he trips the clutch and the machine imn 1ediately drives the staple which it made and positioned in the nozzle during the preceding cycle. The machine then continues to operate until it has made another staple and positioned it in readiness to be driven in the next succeeding cycle. 7
