NAIL DISTRIBUTING AND FEEDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 379.330. dated March 13, 1888.

Application led October 27, 1887. Serial No. 253,485. (No model.)

.To all whom it may concern:

Beitknown that l, FREEBORN 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 Distributing and Feeding Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specication, in explaining its nature.

The object of the invention is to provide a simple and efficient means for distributing and feeding nails in gangs or groups to a nail carrier or templet, or to nail-conducting passages.

The invention is represented as embodied in a machine containing nail -making devices similar to those described in the application of Chester C. Small, led April 21, 1887, Serial N o. 235,648, and no description of the nailmaking devices is herein necessary, it being sufficient to state that the nails are made and' delivered in successive order through a throat.

In the drawings, Figure 1 is a view in side elevation of a machine having the features of my invention. Fig. 2 is a view in rear elevation thereof. Fig. 3 is a central vertical sec- 'JOD.' upon the line x w of Fig. 3 and in plan of the parts below said line. Figs. 5, 6, and 7 are detail views.

A is the throat of the machine. This throat is formed in a nozzleor block, a, and there is arranged below it a nailreceiving block, B, which has anumber of nail-receiving holes, b, therein, arranged in a circular order. The nail-receiving block has holes for the largest number of nails which it may be desirable to distribute and drive at any one time. It is mounted upon the shaft b and has a holecovering plate, b2, which rotates with it and which has perforations or holes b3, adapted to be brought into line with the holes b when it is desirable to discharge them or permit the nails which they carry to escape from them. This plate is moved to cover and uncover the holes, as hereinafter described. There is formed upon the periphery of the block B a ratchetwheel, C, by which the block is rotated in con- Fig. 4 is a view in horizontal section nection with the feed-pawl c with an inter- 5o rupted or intermittent movement in one direction. This feed-pawl c is carried by a slideblock, c', and is operated by. a cam, c2, upon` the shaft c3 of the nail-making /machine and the lever 0*. The block also has the ratchetwheel D, the teeth of which number the same as the teeth of the ratchet C, but lare oppositely inclined. This ratchet operates in conjunction with the pawl d and the feed-pawl c to accurately lock the block at the end of the feed movement of the pawl c, so that each hole b shall register with the throat A. This locking-pawl d Ais operated by means of the cam d on the shaft c3 of the nail-making machine and the lever d2.

The operation of this part of the machine is as follows: The cams d' c3 are timed so that the stop-pawl d is moved into a position slightly in advance of the end of the feed movement of the feed-pawl c, to act as a stop or abutment against which a tooth of the ratchet D shall come in contact, and the feed-pawl c, by contact with a tooth of the ratchet-wheel C, continues to move theblock forward until a tooth of the ratchet D comes in contact with the end of the pawl d. This causes the block to be locked between the two pawls, and after the hole which is in register with the throat has received its nail the cam c2 acts to withd raw the pawl c to permit it to engage the next tooth of the ratchet-wheel C in order, andthe cam d then acts to withdraw the pawl d and holds it until the tooth which it engaged has passed beyond it sufficiently to clear its point, when it is again moved forward to act as a stop.

The object of the block B is lto permit any desired number of nails to be made upon a forward movement of the block in one direction and to be delivered upon the rotation of the block in the opposite direction, and in order to permit this reverse rotation to take place it is of course necessary to disengage the feedpawl c from the ratchet-wheel C.

To return the block B to its original position, or, in other words, to provide it with a reverse 'movement of rotation, there is attached to it the drum'l, (see Fig. 1,) to which the end of a. draw cord or rope, b, is attached. This drawcord extends over a pulley, bs, and carries a weight, bl. To hold the block B when it is moved forward by the ratchet c against the pull of the weight bi, I use a detent, E, which engages the teeth ofthe ratchet-wheel C and serves to hold the block B while the feed-pawl c is being moved backward to engage the next comes in contact with the detent-pawl E and moves it from engagement with the ratchetteeth sufficiently to permit the spring-latch f3 to engage it and hold it disengaged from the ratchet-teeth C, and the detent-pawl occupies this position until it is released at the end of the'return movement of the block B, when the latch f3 is disengaged from the detent E by means of the lifting-lug f4 on the block B, which,riding under the end of the spring-latch f3, lifts it sufficiently to allow the spring ofthe detent E to move it to its normal position.

To operate the hole-covering plate b3, I have provided the plate with an arm, g, which is adapted to come in contact with the stop g' at the end of the backward movement of the block B. This causes the plate to be turned sufficiently to bring its holes in register with the holes b. Upon the forward movement of the block B the spring g2 turns Vthe plate immediately upon the starting of the block sufciently to close the holes.

I have represented as used in connection with the block B a distributer, H, which comprises the block b, made upon the arc of a circle, having holes b, which are arranged upon the same line and order of the holes b of the nail-holder B. The holes lL are connected by passages h2 in the tubes h3 with a stationary nail-holder, h4, or directly with a nail-carrier or a templet.

It will be observed that by means of this block B any desired number of nails may be received for delivery from one to the largest number of holes in the block; also, that the block is always returned to its original position to deliver its nails, being automatically stripped or disengaged from its feeding mechanism upon the making and delivery to it of that number, and is then automatically returned to its original position, and the nails as received are automatically delivered to the passages of the distributing-tubes.

The mechanism for starting and stopping the nail making or supplying devices is similar to those described in said Small application. v

Having thus fully described my invention,

.I claim and desire to secure by Letters Patent of the United States- 1.
