Application filed April 23, 1904. Serial No. 204,567.

To all whom, it may concern.-

Be it known that I, JOHN A. MILLIKEN, a citizen of the United States, residing in the borough of Brooklyn, city of New York, county of Kings, and State of New York, have invented a new and useful Nail and Rivet Delivering Machine, of which the following is a specification.

My invention relates to machines for delivering nails, rivets, &c., to a fixed point, where they will be retained until the operator has inserted them in their proper place in the article to be secured, when they are released, and the particular machine shown in the accompanying drawings and described herein is adapted to the needs of purse and bag makers.

In the drawings similar reference characters relate to similar parts throughout the several views.

Figure 1 is a side view of a machine embodying my invention. Fig. 2 is a View of the opposite side. Fig. 3 is a top view. Fig. 4 is a detail view of the aws in open position. Fig. 5 is a sectional view on the line m of Fig. 4. Fig. 6 is a sectional view on the line y y of Fig. 3.

The machine proper is mounted on a standard 1, which is flanged at the bottom to permit its being fastened to the floor or table. A platform 2 is secured to the top of the standard 1. This platform 2 has an extension 3, which affords a bearing for the driving-shaft. A pulley 4 is secured to the outer end of the shaft, and a clutch is provided of the ordinary type permitting one full revolution of the shaft with the driving pulley and then automatically releasing it, permitting the pulley to run free. A bevel-gear 6 on the opposite end of the driving-shaft meshes with the bevel-gear 7 on the end of a driven shaft 8, extending through the platform 2 at right A cam 9 is mounted on the other end of the shaft 8. Uprights 10 and 13 on the platform carry an inclined slotted chute or guide 11, which has a suitable hopper 12 hinged at the upper end thereof.

A depending lug 14 carries the bell-crank 15, which is pivoted at 16. A connectingrod 17 is secured at one end to the hopper and at the other to the horizontal arm of the bell-crank. The vertical arm is provided with the friction roller 18, which is held against the cam 9 by the spring 19.

The front end of the platform 2 is cut out at 20, leaving the horns 21 and 22 on either side thereof. A rook-shaft 25 is carried in bearings in these horns and has the lug secured thereon between the horns, the lug 35, carrying the clamp- jaws 30 and 31, constituting the holder for the nails or rivets. A crank is secured to the shaft 25 on the outside of the horn 22 and is connected to the vertical arm of the bell-crank 15 by the rod 41.

The side edge of the platform 2 is grooved at 50, Fig. 1, and the slide-block 51 works therein, being held in place by the plates 52 and 53. This slide-block 51 is provided with a depending lug having a beveled face 54 on the rear side thereof, which works in the recess 55 in the platform 2. A pin 56 is mounted on a collar on the shaft 8, and the slideblock 51 is normally held against this collar by the spring 58.

A cam 60 is mounted on the shaft 8 between the bevel-gear 7 and the platform 2. In the other edge of the platform 2 another channel 61, Fig. 2, is out having the slideblock 62 therein. This slide-block is beveled at the front end and is held in place by the plate 63. A friction-roller 64 011 the rear end of the slide-block 62 bears against the cam 60, the pressure being maintained by the spring 65. A finger-piece 7 O is pivoted in the channel 61 at 71', the rear end being beveled and meeting the beveled end of the slide-block 62. The outer end of the finger bears against a pin 72, which extends through the shaft 25 and bears against a lug 34 on the jaw 31[ This jaw-lug 34 extends through openings in the side of the lug 35 and shaft 25.

The nail or rivet holder is composed of two jaws 30 and 31, which are pivoted to the lug 35 at 37 and 38 and which are normally held together at their lower ends by the spring 39. These jaws 30 and 31 have the tapered nicks in their lower meeting faces. A spring 81 on the side of the jaw 30 normally holds a pin 82 across the wide rear part of the notches 80. This pin,which extendsthrough a hole in the jaw and is secured to the spring, is retracted or withdrawn on the upward movement of the jaws 30 and 31 by the wedge 83, which is secured to the platform 2 and which passes between the jaw 30 and the spring 37, thereby forcing them apart and carrying the pin 82 out of the notches.

The bottom of the slotted chute 11 is provided with an upright 90, carrying a springplate 91, which is fiXed at its upper end and whoselower end normally closes the end of the chute-slot, but is adapted to move forward to permit the passage of the nails or rivets. A small block 92, having a funnel-shaped opening therein, is secured to the platform, with the opening at the foot of the chute-slot, the small outlet end alining with the nicks 80 in the inner faces of the jaws 30 and 31 when raised, as shown in Fig. 5.

A small chisel-pointed pin 95 is inserted through a hole adjacent to the end of the chute-slot 1 1. This pin is normally held out of the slot by the spring 96, but engages the bevel cheek-piece 97 and the slide-block 51 on its forward movement. The bottom part of this cheek-piece 97 is adapted to engage the bottom of the spring -plate 91 on the continued forward movement of the slideblock 51.

Having thus described the construction of the machine, I will proceed to explain its operation. The hopper 12 isfilled with nails or rivets and power is applied to the drivingpulley 4. On throwing the clutch 5 into operation (preferably by means of a treadle connected with the rod 49) the shaft and pulley rotate together, the gears 6 and 7 transmitting motion to the shaft 8, cams 9, 60, and 56. The cam pushes the slide-block 62 forward, the beveled end wedging behind the beveled end of the finger 70, thereby pushing the pin 72 against the lug on the jaw 31 and moving its lower end away from the lower end of the jaw 30 against the action of the spring 39. On the continued motion of the pulley and shaft the cam 9 engages the roller 18 on the bell-crank 15, throwing the hopper 12 in the position shown in dotted lines in Fig. 1. The nails or rivets will now feed down the chute v 11, the points falling through the slot and the heads remaining above the chute, as shown in Fig. 5, the spring-plate 91 closing the end of the slot and holding back the line of rivets. The connecting-rod 41, acting on the crank 40, turns the jaws 30 and 31 into a horizontal position, with the nicks 80 directly under the funnel 92 on the platform, as shown in Fig. 5, the wedge 83 drawing the pin 82 out ofthe nicks 80. On the continued movement of the driving-shaft the pin-cam 56 bears on the beveled face of the block 54, pushing the slide-block 51 forward, the bottom of the cheek-piece 97 striking the bottom of the spring-plate 91, pushing it forward, the pin 95 being pushed across the slot in the chute 11 behind the first rivet, holding back the others in the chute, while the first one is free to pass into the funnel in the block 92, thence into the nicks 80 in the open jaws 30 and 31.- The pin-cam 56 then clears the face of the block 54, and the slide-block 51 is returned to its initial position by the spring 58, the spring-plate 91 again closing the end of the slot in the chute 11, the pin 95 being retracted by the spring 96. The slide-block 62 then begins its return movement, permitting the finger to move out, relieving the pressure on the pin 72, the jaws 30 and 31 coming together on the shank of the nail or rivet under the action of the spring 39. The cam 9 now moves the bell-crank 15, lowering the hopper and returning the holder to its original position, the pin 95 returning to its initial location, but behind the head of the nail or rivet. These operations take place in the order described on one full revolution of the driving-shaft. The clutch now disengages the pulley, and the latter runs free until another rivet is desired, when the operation of the clutch starts the machine, releases the rivet in the jaws, and repeats the operation just described.

This machine is especially useful to purse and bag makers, as it enables the rivets to be speedily applied to the frames and leaves both of the workmans hands free to hold the parts together and push the rivets into position. The metal frames of purses are usually made with the rivet-holes punched therein, the purse material and lining being placed between the inner and outer frames and the Whole riveted together. Pointed rivets are used, so they can be forced through the purse material, the points being afterward cut off and the riveting done in the usual manner. Heretofore these pointed. rivets have been held in apair of pliers and then inserted. By the use of my invention the rivets are presented pointed end out at a fixed point, where they are firmly held while being inserted in the purses or bags.

It is obvious that the machine can be used to deliver nails, rivets, buttons, or similar articles and that it can be combined with ma chines for performing various other operations.

The word rivet in the claims is merely typical and not limiting, and I include thereunder nails, buttons, or other similar articles.
