NAIL MAKING AND DISTRIBUTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 380,596, dated April 3, 1888.

Application filed October 2'7, 1887. Serial No. 253,484. (No model.) i

To aZZ whom it may concern.-

Be it known that I, Fannnonn F. RAYMOND, 2d, of Newton, in the county of Middlesex and State of Massachusetts, a citizen of the United States, have invented a new and useful Improvement in Nail Making and Distributing Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this-specification, in explaining its nature, in which Figure 1 is a view in side elevation of the machine. Fig. 2 is a view in rear elevation, a portion of the machine being broken out to represent the operation of the throatclearing device, hereinafter described. Fig. 3 is a vertical section of the machine. Fig. 4 is a plan View of the pattern-plate for holding the tube ends, hereinafter referred to. Fig. 5 is a view in horizontal section and plan upon a line over the ratchet-wheel upon the nail-holder. Figs. 6 and 7 are detail views. Fig. 8 is a View in perspective of the nail-receiving block and distributor.

This invention maybe called an improvement upon that described in the application of Chester C. Small for patent for improvement in nail making and distributing ma chines, filed April 21, 1887, Serial No. 235,648, the nailmaking devices being substantially identical with those therein described, and comprising a roll, A, having a box-pointing die, a, a roll, A, having a nail-pointing die, a, a shaft, a, supporting the roll A, the shaft a, supporting the roll A, (which shafts are geared together,) the wire-feed rolls B B, and the nail-cutters G O, operated by the cam or abutment c, as described in said patent application. The feed-rolls are also operated substantially as therein described-namely, by a ratchet-wheel, b, upon the shaft of one of the rolls, the pawl 12, arranged to engage the teeth of the ratchet-wheel, mounted upon a swinging arm b, which is pivoted at b and is oscillated by a crank, b, on the roll-shaft a and the connecting-rod b D is the throat or passage through which the nails are delivered from the naihmaking devices to the nail-distributor. The nail-distributer comprises a nail-holder, E, having a series of nail-receiving holes, e, located in a circular order or arrangement at a uniform distance apart. (See Fig. 8.) The nail-holder E also has the central hole, 6, which fits on the stationary stud e, which forms a bearing for it. The block also has a nail-hole-covering plate, 6 which has perforations e, and which is adapted to be moved to cover and uncover the holes 6. This plate is attached to the holder E, to be rotated therewith, and is moved at the end of the rotation of the block both to uncover and to cover the nail-holes. The holder also rests upon the circular bed 6 extending from the stud 6", preferably integral therewith, although not essentially so. The holder E also has the ratchet-teeth 6 formed upon or in its exterior surface near the lower end, or, preferably, in a ring or wheel fitted to said surface. The block is provided with intermittent periods of rotation and rest by means of a feed-pawl, 6, (see Fig. 5,) which is carried by a slide, a arranged to move in the dovetail ways e upon the side ofthe frame E. (See Figs. 1, 2, and 5.) Suitable movements are given the slide-block, and consequently the pawl, by means of the crank F on the shaft 0., the leverf, pivoted or having a fulcrum atf, (see Fig. 1,) and provided with three armsnamely, the arm 1", which is con nected by a connectingbar, f with the crank F,the arm f which is connected with the slide-block a carrying the pawl, by the link f, and the arm f which is connected by devices, hereinafter specified, to a clamping device adapted to be moved in the throat D.

The extent of the effective throw of the pawl is adjusted by means of the gibf, (see Fig. 1,) which is held in the slide 6 in the guideway e" by means of screws f in a manner to be horizontally adjustable, and which also has the inclined end f which projects in line with the movement of a pin, f, on the feed-pawl 6 (See Fig. 1.) This pin is arranged so as to come in contact with the incline f upon the backward movement of the pawl, and the time of engagement of the pawl with the tooth of the ratchet wheel is determined by the position of this incline f If the gib f is set forward, then the effective stroke of the pawl is less. If it is set back, the effective strokeis greater. The successive periods of movement ;and rest thus given to the block E bring each of its nail-receiving holes 6 successively in line with the throat l),

the holder being located so near the devices for pointing and severing the nail that the nails can be fed very rapidlyito its holes, and also in a straight line.

To deliver the nails from the holder E into adift'erent form than a circular one andvin any arrangement for driving, I employ the stationary nail-distributing tubes G. Each tube has a passage of sutticient size to receive a nail and permit it to pass freely through it. The tubes are held at their upper ends quite loosely in the enlarged holes 9, formed in the under surface of the plate 6 (See Fig. 3.) The plate has perforations or holes formed in it in said circular order as the nail-receiving holes e of the nail-l1older E. The tubes are curved or bent to bring their lowerends into any desired arrangement in relation to each other, and they are held in such arrangement by means of a plate, G, (see Fig. 3,) which has holes 9 formed therein in the arrangement desired, and which are enlarged at their tops g to receive and hold the lower ends of the tubes G. This plate is attached by a screw,

9, to a downward extension of the stud efland so as to be removable therefrom. The holes are of a size to quite loosely hold the tubes, and by removing the plate G and substituting another plate having the same number of holes, but bearing a different relation or arrangement to each other, the same tubes G may be used, or, if desired, the tubes G and the plates G may be removed and other tubes G having other curves and another plate G having ,a different arrangement of holes may be substituted.

The distributer acts to receive nails from the holder E at the end of its rotation and to deliver them directly as a gang or group through the holes g in any desired order or arrangement into a nail-carrier or perforated heel-blank or any other suitable receptacle.

In Figs. 2 and 6 I have represented aclearer, H, arranged to be moved into the throat or passage D immediately below the converging point on the dies (1 a, and then downward therein to or very nearly to its lower end, then outward from the throat and upward to its original position, its offiee being to enter the throat immediately after the making and delivery to the throat of a nail and to move downward vertically therein to push the nail from the throat into its appropriate nail-receiving hole in the holder E if it shall not have dropped sufficiently fast by gravity, or if held back by friction or forany other cause. To enable this to be done, there is formed in the casing of the throat D a narrow vertical slit, (2, of a width to receive the clearer H. The clearer is arranged to project from the plate h, and it has an inclined upper edge, h. (See Fig. 6.) The plate It has a roll, h, upon each side, which enters the vertical guidingrecess h The plate is moved vertically by means of the connecting-rod h, rock-lever h, having two arms, oneof which connects with the link h and the other with the link h extending to the lever f. The link It is connected with the plate It at its corner h and at one side of the rolls h so that upon the downward movement of the plate, the rolls h offering more resistance to the downward movement than to the swinging or turning movement thereon, the plate is first turned upon the rolls h sufliciently to cause the clearer H to enter the throat. The extent of this movement is limited by means of the arm h which is fixed to the end of the link h and the pin it on the plate. This relation of the parts will continue during the entire downward movement of the link.h-that is, the plate will be inclined to the link and the clearer will move downward in the throat. of the link h exactly the opposite effect is producedthat is, the upward movement of the link it turns the plate upon the rolls h to the position shown in Fig. 6 and draws the clearer H from the throat. The extent of this move ment is limited by the stop-bar h and pin h upon the plate, (see Fig. 6,) and the plate and clearer bear this relation to the throat and link h during its upward movement.

The spring h, fastened to the link and to Upon the reverse movement the frame of the machine, holds the link in proper relation to the rolls h of the plate during its movement.

It will be seen that the clearer has practically four movements in the throat: first, an inward movement above the head of the nail; second, a downward movement to force the nail from the throat; third, an outward move- After each nail has been made and downward in the throat, and each hole of the holder is brought in register. The nail-holder E is arranged as closely to the nail-making devices as possible, and is not much over the length of the longest nail which it is desired to make from them, so that each nail has but a short distance to travel to enter the holder, and the clearer H also has a short movement. This insures two things: first, the sure feeding 3 of each nail to its nail-receiving hole, and, second, great rapidity of action. nail has been made and delivered, the nailmaking devices come to rest, and the nailholder is also stopped in position to deliver its nails to the distributer. The start and stop motion mechanism is similar to that described in said Small application.

After the last The holder E mayhave suitable friction apend of the feed-stroke of the pawl.

plied to it for retarding its momentum at the V The nail-holecovering-plate of the holder E is moved at the end of the movement of the block E to uncover the holes 6, and the nails then drop as a gang from the nail -holder through the distributing-tubes to the nail-carrier G".

The nail-holder and distributer are removable from the machine, the frame of the machine having the recess F, (see Figs. 2, 5, and 7,) of a size and shape to receive the holder, and also having a shoulder, at, upon which the under surface of the plate 6 near its outer edge bears, (see Fig. 7 and it may be held in place additionally in said position by a screw, button, or any other suitable locking device.

It is necessary to remove the block and distributer when the number of nails which it is desired to make vary; but it is only necessary to remove the pattern-plate G and the tubes G when only the order or arrangement of the holes is variedthat is, the order or arrangement upon which they are delivered from the distributer-while the number remains the same.

A machine of this construction has great capacity and accuracy and is cheaply made.

The nail-hole-covering plate 0 is shown in Figs. 5 and 8, and in Fig. 8 it is represented as having a projection, M. This projection has an inclined edge which comes in contact with astationary projection having an inclined edge as the block E approaches the end of its movement, which causes the plate (2 to be moved horizontally across the block E in opposition to the springm, (shown in dotted lines in Fig. 5,)so that the holes of the plate 6* are brought in register with the holes e of the block E. and upon the forward movement of the block E the projection lV of the plate e passes or is moved by the stationary projection and permits the spring at to close the holes e by moving the plate to the position shown in Fig. 5.
