15 Claims.

This invention relates to a device for'supplying fastenings and is illustrated herein as embodied in a device arranged to supply fastenings one by one in such a manner that they can con- 5 veniently be picked up and transferred to the places where they are to be driven. I

Tacks and other fastenings are frequently driven by hand in the manufacture of shoes and it has been the practice of operators,-particularly side lasters, to employ the unsanitary practice of keeping their supply of tacks in their mouths as they have found that they can take the tacks from their mouths more readily than they can pick them from a receptacle.

It is an object of the present invention to improve upon the construction of devicesfor supplying fastenings.

In accordance with this object the invention, in one aspect, comprises a device for supplying fastenings having a-separator located in a raceway arranged to control the passage of. headed fastenings supported in the raceway and a member arranged to support and receive a separated fasteningfrom the raceway and arranged when displaced laterally to effect the operation of the separator to permit a fastening to pass the separator.

of the raceway to prevent loss of tacks.

The

tacks or other fastenings may be picked from the U-shaped member by hand or with the jaws of a pair of lasting pincers and thereby transferred to and lightly driven into the shoe upper and.

last which is being operated upon, after which the driving may be finished in the usual way.

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

In the drawings,

Fig. 1 is a perspective view of a device for supplying fastenings arranged in accordance with the present invention;

Fig. 2 is an enlarged view of the lower end of the raceway with a tack in positi moved from the device;

on to be re- Fig. 3 is a view similar to Fig. 2 showing parts of the device displaced laterally;

Fig. 4 is a view of the lower end of the raceway on a much enlarged scale; and

Fig. 5 is a view partly in section taken along the line V-V of Fig. 2.

The fastening supplying device of Fig. 1 is carried by a bracket 10 forming part of or carrying a hopper or tack pot 12 by which fastenings 14 may be supplied in any suitable manner to the upper end of a raceway 16. The upper end of the raceway may be provided, as disclosed in United States Letters Patent No. 1,761,031, granted June 3, 1930 on application of James F. Alkonis, with a pair of diverging plates directing the tacks to the raceway as they fall from plates carried by a rotating portion of thehopper 12. The raceway 16 is made up of a pair of plates 18 and 20 spaced apart to form a tack receiving slot 22 in which a line of headed fastenings is supported and provided with a suitable cover 24 secured to the plates 18, 20. The raceway is inclined, as clearly shown in Fig. 1, and is provided at its lower end with a substantially U-shaped member 26. The U-shaped member 26 is formed of spring steel or of other resilient material and is secured to the plate 20 by means of cap screws 28, as shown in Figs. 1, 2 and 3.

The member 26 is provided with a slot 30 which is normally in alinement with the slot '22 in the raceway whereby fastenings may pass readily from the raceway and into the slot 30. It is to be noted that the member 26 is arranged to be displaced laterally when a tack or other fastening is being removed from the closed end of the U-shaped member. A laterally projecting portion 32 forming part of the member 26 closes the end of the raceway when the U-shaped member 26 is moved from its normal position. The slot 30 in the member 26 is maintained of substantially the same width at all times by means of a collar 34 which is placed between the walls of the slot and held in place by a bolt 36 passing through the collar and through the walls of the slot. The bolt is maintained in this position by means of the nut 38 which, together with the collar and screw, clamps the walls of the slot 30 in position. The collar 34 will be selected to have a thickness in accordance with the width of the slot 22.

A separator finger 40 is secured to the extension 42 of the U-shaped member 26. This separator passes through a slot or recess formed in the extension 42 and is secured to the extension 42 by means of a nut and bolt 44. The separator 40 is normally maintained in the position shown in Fig. 2 but may be displaced in one direction by movement of the U-shaped member 26, thereby permitting the tacks in the raceway to move downwardly and when the member 26 is returned to its original position the point of the separator finger enters between the endmost tack in the raceway and the next tack. The endmost tack is then moved under the influence of gravity to a position at the closed end of the member 26.

The displacement or the member 26 (and consequently the separator finger 40) is limited by means of a cap screw 46 which forms an ad justa-ble stop against which the extension 42 of the member 26 contacts. The cap screw 46 is threaded into a U-shaped strap 48 which in turn is secured to the raceway by a screw 49 and which assists in holding the lower ends of the members l8 and 20 in proper relation to each other. By adjusting the cap screw 46 the movement or displacement of the member 26 may be varied in accordance with the width of slot 22, thereby insuring that the point of the separator finger 40 will, at all times, when displaced to its limit, be entirely removed from the slot 22, thus insuring that the fastenings will be free to move down the raceway and against the outturned portion 32 of the member 26. The point of the separator finger 40 is spaced from the end of the raceway a distance greater than the diameter of the shank of the fastening immediately below its head. This spacing of the point of the separator finger from the end of the raceway insures that only one tack or fastening will be separated from the line of fastenings in the raceway.

Although the parts of the device have been described in detail it is believed to be desirable to summarize briefly the operation of the device. With the parts of the device in the position shown in Fig. 2 the operator, either by the use of his fingers or by the use of the jaws of a pair of lasting pincers, grasps the fastening 14: in the member 26 and, in so doing, moves or displaces the member 26 into the position as shown in Fig. 3. It will be noted that the separator finger has been moved out of the slot and that the fastenings 14 have moved down to the end of the raceway. When the operator removes the fastening and releases the member 26 the member 26 will be returned to the position shown in Fig. 2 and the point of the separator finger will enter between the last two fastenings in the raceway and when the slot 22 and the slot 30 are in alinernent, as in Fig. 2, the endmost fastening will pass down to the closed end of the member 14.
