BOOT OR SHOE NAILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 356,107, dated January 18. 1887.

Application filed May 15, 1880.

To all whom it may concern.-

Be it known that I, HENRY DUNHAM, of Abington, in the county of Plymouth and State of Massachusetts, have inventedcertain new and useful Improvements in Boot or Shoe Nailing Machines, of which the following is a specification.

My invention relates to boot or shoe nailing machines; and itconsists in certain novel IO combinations of operative parts, specifically set forth in the claims, whereby the nail-holes are made, the nails driven, and the nail-points turned in a greatly improved manner, as will more plainly appear hereinbelow.

I accomplish the object of my invention by mechanism illustrated in accompanying drawings,in which Figure 1 represents a front elevation of a machine having my improvements. Fig. 2is 20 a side elevation of the same. Fig. 3 is. a side elevation representing the side opposite to that shown in Fig. 2. Fig. at is a detached view of the moving frame holding the nailtube and connecting parts. Fig. 5 shows the 2 5 Work-supporting horn and connecting mechanism, and Fig. 6 partly illustrates the unshipping mechanism.

A is the standard of the machine.

B is the head-that is, the part of the machine above the standard.

C is a reservoir for receiving and holding the nails, which pass to the tapering box D, and through the conductor E into the nailway F, which is connected with the frame of the machine in such manner as to have imparted to it a slight forward and backward movement by means of a roller on the end of a small lever actuated by a cam, O. The pulley N is actuated by a belt when the machine is in operation.

At the end of the shaft is a cam having three operating-faces, (marked 1, 2, and 3,) which respectively actuate the driver 1?, the reciprocating throat or nail-tu'be Q, attached to the frame 4 5 R, and the awl S, attached to the arm T. The

arm T is bent in the direction of the work-feeding movement of the awl, and it has a stock, J, which slides up and down in the frame R, having the nail-tube Q attached to it at the bot- Serial No. 9,841. (No model.)

tom. The driver 1? has no lateral motion, but moves in vertical guides of the main frame or standard, being raised by the cam and driven down by a spring on the head B. The feeding movement of the work by the awl is caused by a lateral movementof the frameB in one direction, while the movement of the nail-tube to a position under the driver is caused by a lateral movement of said frame in an opposite direction. Thus it will be seen that the triple cam causes the upward movement of the driver, the vertical movement of the awl, and the lateral movement of the frame R. Further, the awl and the nai1-tnbe severally move from opposite directions to the line of the driver, this in practice being deemed an advantage.

The separator, which is actuated by the lever U, is composed of a flat piece of steel, which passes in front of the opening in the throat Q, and between the lowermost nail and the one next to it, and incloses the lowermost nail in the throat Q, so that it is carried inclosed in the throat under the driver, the separator remaining, closely covering the opening in the throat Q, until the nail is driven, when the separator recedes, leaving the throat open for the reception of another nail.

W is a work-supporting horn, which has a concavity, a, in its upper extremity, the shape of which is adapted to turn the point of the 80 nail into the stock in the form of a circle. This concavity, operating in combination with the awl, is an element of vital importance in my invention. I have found in practice that the use of an awl with the concavity in the horn is essential to good work. The peculiar clinch caused by the concavity is due to the point of the fastening striking the inclined part of the concavity, forming its curvature, and then turningback into the work. It is therefore necgo essary that the fastening be directed to the inclinedpart of the concavity. If it shouldstrike the bottom first, the fastening would be liable to be crippled. The degree of curve in the clinch of the fastening is determined by 5 the distance from the bottom of the concavity at which the fastening strikes. I provide an awl for this purpose which is so operated and adjusted that it makes the holes in the shoesole so that the nails driven therein will strike the incline in the concavity, thereby making aperfect curved clinch. Without this relation of the awl and concavity the nails would be driven without any regularity whatever, sometimes not striking the horn at all, and not even penetrating the shoe-sole. The combination of the awl and the horn is adapted as well to other shoe-nailing machines as to the class in which loose nails are driven. It is adapted to machines in which a fastening is driven which has any kind of a clinchingpoint. The horn is supported by a rod, (1, adapted to work vertically in suitable guides. This rod (Z is provided with a collar, t, which rests upon a coiled spring, 0. This springsus tains the weight of said rod and horn, and yields sufficiently to allow said horn to move downward a greater or less degree, according to the thickness of the stock fed to or placed upon it. The horn also may be depressed by a treadle, I), attached to the rod d. The object of this automatic depression and rising is,that

the horn shall be withdrawn from the stock after every stroke of the awl sufficiently to allow the awl to move the stock without impediment under the driver P,and that as soon as this movement is effected the horn shall be restored to its former position, pressing the stock against the head in such manner as to clinch the nail when driven by the driver.

If in its passage through the stock the aw] should be deflected by striking a hard place in the stock, or from any other cause, when the stock is released from pressure between the head and the horn, the awl will spring back into position and point to the exact place in the concavity on the horn where it is desirable the nail should strike, the stock being held on the awl, and there being nothing to prevent it from taking a straight position.

When it is desired to make the pivotal point or fulcrum h higher or lower, it is effected as follows: The fulcrum h ofthe lever e is fastened to the vertical piece p, which has a slight upward-and-downward movement in guides q. Collar t has a wedge-shaped projection, j, which, when the collar rises, presses against the projection on the lever Z, pivoted at its lower end to the standard A, and pivotally connected at its uppcrend, n, to atoothed wed geshaped piece, 0, which receives pressure from the spring 72, operating in the reverse direction from the action of the projection, and guided by a track or guide, 12 Its teeth engage with similar teeth on vertically-moving piece 19. It will be seen that the pivotal point or fulcrum h is placed higher or lower automatically in accordance with the thickness of the stock.

In many cases it is very desirable to give the horn a fixed depression instead of a variable one, as above described, for the ourpose of making a hole entirely through the\thickest part of a shoe'sole, and it is accomplished as follows: After having set the horn for any given thickness by placing the stock upon it and clamping it between the head and the horn, the screw at the upper end, a, of the lever Zis to be tightened, so as to make the wedge 0 rigid. The piece 2' may be swung around so that it is no longer in contact with the projection It. This done, the horn has a definite and fixed amount of depression, regardless of the thickness of the stock.

The following-described mechanism is provided for instantaneously stopping the machine. The pulley N is made hollow, being open at the inner side toward the main part of the machine. Attached to its outer end is a sleeve, through which the shaft M passes, and it fits closely between a collar attached to the shaft and the rear bearing of the shaft. Closely fitting into pulley N is a smaller pulley, r, having on its inner face a sleeve, through which passes the shaft to which it is keyed, so that the shaft when it revolves causes the pulley 1- also to revolve, the pulley 7' also havinga lateral motion 011 said shaft for the purpose of connecting it with the pulley N. Attached to the shaft, and between the sleeve of the pulley r and the cam, is an arm, 8, attached to theinner pulley, r, by springs t upon rods. This arm is keyed and fastened by a set-screw to the shaft, and it has through its extremity an opening, through which passes one end, 20 ofalever, u, the inner end of which is bifurcated and fits over one-half the circumference of the sleeve of the inner pulley, r, being connected with the sleeve by pins '0 0, working in slots a, some whatlarger than the diameter of the pins. The outer end, a, of the lever to is so arranged that when the lever to, which is attached to a red, at, and treadle y, is raised a short distance, asshown in Fig. 6, the part a impinges against the upper end of the lever 10, and the inner end, it, of the lever to, hearing against the pins 0 e in slots '0, forces out slightly the inner pulley, 1', against the retraction of the springs tt-t, which have heretofore held the pulley, so as to revolve with the larger pulley N, in which it is placed, and as a result the inner pulley no longer revolves with the pulley N, which continues to revolve without and the machine stops at once. 7

The operation of my machine is as follows: A boot or shoe to be nailed is placed upon the horn w, and as the shaft revolves the horn descends, making a hole in the-shoe to receive the nail, the same bfhg pressed by the horn closely against thefoot-piece L, so as to facilitate the making of the hole. By the operation of the lever Z, as explained above, the horn then recedes automatically, and the shoe is. held up by the awl, by which it is fed forward, the awl having a forward movement imparted to it equal to the desired space between the successive nails. At the end of this movement the hole for the reception of the nail is directly under the driver; the awl, now rising and leaving the shoe, returns to the first position. With the forward movement of the awl the nail-tube Q has moved toward the nailturning the shaft,

way F, which itself has also a movement toward the nail-tube. The separator U moves forward and separates the lowermost nail in the nailway from the next one, and it is brought into the nail-tube, and is inclosed there by means of the separator. The nail-tube then recedes, taking the nail directly over the hole made in thevshoe by the awl, and at the same time the concavity a has been brought automatically directly under the nail, pressing the stock against the foot-piece L. The driver now descends and drives the nail, the point of which strikes in the concavity a and is turned back into the stock, the point of the nail forming a circle in the stock.

\Vhat I claim, and desire to secure by Letters Patent, is-
