erence characters on the drawings indicating like parts in the several figures.

This invention relates to mechanism for inserting fastenings and particularly to means for supplying fastenings in an lnserting machine.

The invention has for its object to provide improved means for controlling the delivery of fastenings whereby waste of fas- 5 tenings by delivery to the inserting mechanism when no work is in position to receive them will be avoided.

The invention is herein shown, for the purpose of explanation, as embodied in the tacking mechanism of a lasting machme of the type shown in United States Letters Patent N o. 58&,74;4c, but nothing herein is to be understood as limiting the invention to use in any particular machine except as definitely stated in the claims.

A very important feature of this inven tion consists in the provision in a tack delivery controlling mechanism of means for delivering a tack in position to be driven during the first actuation of the driver after the controlling mechanism has been set to start the delivery of tacks. In this respect this invention possesses a marked advantage over the prior art as represented by the United States Letters Patent No. 663,471. In that construction a complete cycle of operation of the machine is required before a tack is presented for insertion. In the preferred constructions embodying the present supplying mechanism is stopped with a tack in position to be delivered to the driver in its first descent after the supply mechanism is restarted. This feature of this invention has the advantage that no delay occurs in the use of the machine before a tack can be driven, and the further important advantage, when embodied in a lasting machine, that a tack is supplied in position to be driven for holding the portion of upper that is overworked 1n the first cycle of the operation of the ma chine.

It is a further characteristic of the preferred embodiments of the invention that the tack supplying mechanism is not dependent upon the driver for its actuation and can be stopped without necessarily stopping the driver.

An important feature of the invention consists in providing a controllable connect-ion between a continuously moving actuator and the tack delivering devices and means whereby said connection is adjusted automatically when the work, as for example, a shoe, is presented and removed. In the machine shown a cam plate serves as the actuator and receives a continuous reciprocatory movement while the machine is in operation. Cooperating with this cam plate is a lever that actuates the tack separator and causes a tack to be separated from a row of tacks in the raceway and delivered to the tack block at each operation of the machine. I have located a movable shifting device in position to be engaged by the shoe when the latter is presented to receive a, tack from the tack block and have connected this shifter with the tack supplying mechanism so that the latter is controlled by the position of the shifter. In accordance with a further feature of this invention the parts of the tack supplying mechanism are arranged to maintain connection at all times while being ad justed by the shifter to start and to discontinue the delivery of tacks. In an illustrated embodiment of this feature of the in vention the cam plate has a movable connection with its carrier and the shifter is connected with means by which the cam plate is locked in a fixed relation to its carrier. Obviously many other arrangements might be devised which would be the mechanical equivalents of that shown.

In accordance with another feature of this invention the lever that actuates the tack separator is held in operative relation to the cam plate by a movable controlling member which is connected to the shifter and adapted, when no shoe is in the machine, to permit the lever to remain at rest at the outer limit of the throw effected by the cam plate.

A novel characteristic of this invention which is of great importance is that when rating and delivering devices which sepa; rate a tack during their stroke m-one direction and deliver the tack during their return movement. Provision is therefore made that the mechanism shall come to re'st' with a tack separated and ready to be delivered on the first stroke after the mechanism is again set into operation.

A further improvement in the tack supplying mechanism comprised in this invention consists in a novel construction of the feeding mechanism whereby access can be readily gained to the tack separating devices for removing tacks that sometimes get caught or jammed in said devices, or for replacing worn parts of said devices. To

this end the end block or delivery table over which the separated tack is moved to be delivered is formed so that it can be readily detached from the other portions of the feeding mechanism and will expose the separating devices to the view and manipulation of the operator. l V

These and other features of' the inven tion, including certain details of construction and combinations of parts, will be more fully explained in connection with the following description, and will then be pointed out in the claims.

Figure 1 is a side elevation of a portion of the lasting machine, before referred to, with the present improvements applied thereto; Fig. 2 is a sectional plan View on the line 00a2 of Fig. 1; Figs. 2 and 2 are views showing different positions of the parts illustrated in Fig. 2; Fig. 3 is a side view showing another construction; Figs. 4 and 5 are plan views showing in different positions parts that appear in Fig. 3; Fig. 6 is a perspective view of the end portion showing the raceway and the tack feeding mechanism, and illustrating also means forremovably attaching the end block or delivery table of the raceway; Fig. 7 is a sectional view showing the latch for the delivery table.

' ersing the end of the raceway, passes between the lowermost tack in the raceway groove that occupies the operative position and the tack next above the lower one. A delivering plate 6 having a pointed finger 8 and a slot 10 inclined to the path of its movement forces the separated tack toward the discharge opening 12 in the table orend block 14 Fig. 7. The separating and delivering devices4 and 6' are connected for endwise movement to a rack bar 15 that is engaged by teeth on the frontend of a lever 20. This lever is shown as formed in two parts which are connected to yield against the'pressure of the spring arranged inn socket in one part of said lever and pressingagainst a plunger 2-2 which engages the other part of the lever. Thelever has a roll 24 on its rear end that engages the inclined face of a cam plate 25. This plate is permanently mounted upon its carrying slide 26 which is connected to the main shaft of the machine for continuous endwise reciprocation as shown in said Letters Patent N 0. 584,744. The slide 26 also carries the tackblock 28 which has the driver passage 30 provided with any usual tack sup-.

porting fingers. The tack block moves from aretracted position where it receives a tack from the discharge opening in the end block 14 to an advanced position over the work and under the driver 32. In this movement the cam plate advances, throwing the rear end of the lever 20 outwardly and carrying the front end to the left and the tack separating and feeding devices into the position in which they are shown in Fig. 2. In this position the lowermost tack in the operative raceway groove can slide down into the inclined slot 10. In the normal operation the reverse or backward movement of the tack block will be accompanied by a reverse movement of lever 20 forced to the discharge opening 12 through which it will fall into the driver passage of the tack block at the time the latter reaches its receiving position.

In the construction shown in Figs. 1 and 2 the movement of the lever from the position shown in Fig. 2 for delivering a tack is efiected by a movable cam plate 40. 'This' plate is pivoted to a plate 25 fixed to the slide 26 and has a face 42 which preferably is at all times in contact with the roll 24 and which, with the plate 25, forms an inclined track for the roll. This inclined cam path, when the parts are in the position shown in dotted lines in Fig. 2, compels the rollto move inwardly as the plate moves ba.ck-

gages the inclined spoon-shaped face 54 of the bar 40, rocking that bar into the dotted line position and positioning the rollv24 and.

the separating devices connected with it in their proper relation to the plate according to the point in the cycle of the machines operation at which the presentation of the shoe takes place. This provides that a tack will then be delivered in regular time relation to the movements of the driver and other operating parts of the machine. Fig. 2 shows in full lines the position shown in dotted lines in Fig. 2 and Fig. 2 shows the position of the parts when the tack block has advanced with the tack to a position under the driver. As the shoe is presented the plunger 45 is forced inwardly against the cam plate 40, forcing it into operative position relatively to its driver and, finally, slides on to the spoon-shaped end 54:, Fig. 2*, of the cam plate whereby the cam plate is locked in position relatively to the plate 25 and its driver and remains in that position as long as the plunger remains in, or the shoe remains. in, position. It will be seen that the bar 45 is in locking engage ment with the end 54 of the cam 40 some time before the shoe is fully in position to be operated upon. The end 54;, as the machine operates, slides back and forth along the plunger 45 and when the plunger is forced in to the fullest extent by the presentation of the shoe, considerable movement of the plunger must take place before the cam plate 40 becomes unlocked and the separating devices are rendered inoperative, just as is the case with the lock 66 of Figs. 3, a and 5 of the drawing. If the cam plate 25 is in its retracted position shown in Fig. 2 actuation of the cam plate 40 by the op erating member 50 will move the lever 20 and cause the delivering device to move toward the right and drop a tack at once into the tack block. If the operating member 50 is actuated when the parts are in any other position than that shown in Fig. 2, then it will cause a tack to be delivered in the same cycle of the machines operation and as soon as the tack block does reach its tack receiving position. By this provision for stopping the supplying devices with a tack in the delivering device the operator does not have to wait until the machine makes a complete cycle for separating and then delivering a tack, as it would have to do if it were stopped at the other end of its throw or if the lowermost tack were stopped in the raceway above the separating devices. This is of particular importance when the grippers 55 are employed and the tack is depended upon for securing the portion of upper pulled by the grippers. An adjustable stop 56 is shown for positioning the separating devices accurately with relation to the raceway groove.

1n the construction shown in Figs. 3, 4 and 5, which also possesses the advantage that the mutually contacting parts of the driving and driven members of the separator The cam plate has also a slot at 65 that is adapted to receive the controlling device 66 which is a bar movable vertically between the slide 26 and a cap plate 68 mounted on the slide 26. The bar has a shoulder 69 that rests upon a lifter 7 0 which is supported by the parallel links 7 2 and 74, on the latter of which is formed the operating member 75. A spring 76 holds the operating member and. its connected parts in the position shown in full lines in Figs. 3 and 5. \Vhen the said member is rocked about its fulcrum 78 against the tension of spring 76 the lifter is lowered, allowing the controlling device 66 to drop upon the cam plate, and the spring 80 forces said device into the slot 65 the neXt time the slot comes under the device. When the controlling device is lifted the cam plate continues its reciprocatory movements with the slide 26 to which it is always connected, but it has in addition a swinging movement about its pivotal connection at 62 and the spring 82 is permitted to hold the lever 20 always in the position shown in Flg. 5 and determined by the stop 56 with a tack ready to be delivered as soon as the controlling device is adjusted.

The operating members 50 and 75 are each shown as arranged relatively to the shoe bottom rest 85 of the lasting machine in position to be engaged and moved by the shoe while it is being presented in position to receive the tack. By this arrangement the controlling device is operated without special attention from the operator to cause the feed of tacks to be commenced when the shoe is put into position to receive the tacks.

12 The end block or delivery table 14 is preferably attached to the raceway for convenient removal and for this purpose the supporting plate 90, whichis permanently attached to the raceway by the screws 91, has an open ended slot 92 to receive a guiding stud shown as a screw depending from the lower face of the delivery table. The raceway, or the raceway supporting bracket, has a positioning stud 93 project-ing from'its end face which fits into a socket in the face of the table 14. The raceway bracket also carries a latch 94, the shank of which is acted upon by a spring that presses the latch rearwardly and holds its front hookshaped end in a seat 96 in the front face of the table. A guiding thimble 97 embraces the rear end of the shank of the latch and the spring while a second thimble 98 is similarly fitted over the front end of the spring and has an outstanding handle 99 which projects through a bayonet joint slot 100 in the supporting bracket. This arrangement provides that the handle can be moved rearwardly in the locking port-ion of the slot 100, compressing the spring by sliding the thimble 98 rearwardly and then the handle and thimble can be turned until the handle is in the long arm of the slot, after which it can be moved forwardly, relieving the tension on the latch which can be unseated and turned to release the delivery table which may be removed by a forward movement which will free it from the stud 93 and the slot 92. Reverse manipulation of the parts will restore the delivery table securely in operative position. The occasion for removing the delivery table to obtain access to the feeding devlces arises fretquent-ly because of the presence of misformed tacks or foreign matter which clogs the delivery mechanism, and it is therefore of great advantage for the operator to be able to remove the delivery table quickly without the use of machinists tools.

Having explained the nature of this in vention and described a preferred construction embodying the same, I claim as new and desire to secure by Letters Patent of the United States driven while the machine continues in operation, mechanism for controlling the feed- 1ng of fastenings constructed and arranged to cause the feeding mechanism to be started and stopped independently of the driver and to deliver a fastening into posit-ion to be inserted in time relation with the first descent of the driver after the controlling mechanism has been set.
