M. Rnoons and J. G. RHO ES, of Taunton, in the countyof Bristol and State of Massachusetts, have 1nvented a new and useful Machine for Leathering Tacks; andwedo hereby declare that the following isafull, clear, and exact description of the same, reference being hadto the accompanying drawings, forming part of thisspecification, in which--= v 1 Figured, is a side view of the machine;

A, B, G',l D, is theft mingjof the machine consisting of abedwplateA, a standard B,

and two guides G, 11D, toureceive a vertical sliding cylinder-Eu? Thisllvertical sliding cylinder is placed over a stationary. ring: punch a, sucli as is commonly used for cut- 1 ting leather, which is securedto the bed plate A;and ituhas an arm bywjhich is, rigidly secured a to its! upper end and coni nectedbylinks c,c,to a leverF,which works i on ajfulcrum d, at the top ofthe standard Thislever is intended .to receive an oscilhlating motion' wlhich "gives the cylinder a reciprocating motion brings its lower end in i contactwith the edge of the punch andlifts itgtherefrono for thepurpose of cutting the circular pieces of leatherwfor thetacks, from i stripswhichare fed by hand across or over the punch; The cylinder E, is made hollow throughout for the purposes ofreceiving the ftacks near its bottom, and of containing a a h driver G, to drive thetacks through the 1 leather as soon as the latter is cut. The driver Gr, consists of a cylindricaliro-n or steel rod, the; lower part ofwhich is made of a diameter little greater than the heads of the tacks, but theupper part is made larger for tlie sake of greater stiffness. The cylinder is bored to allow the driver to slide easily withinitl The driver is attached to the front extremity of the lever F, and as the cylinder is} connected much nearer the fulcrumythe driver receives a movement of much greater length than the cylinder.

The tacks enter ,the cylinder in an upright position or nearly so through an opening or mouth 0, in one side, as shown in Fig.

Specificationof Letters Patent No, 12,832, dated May 8, 1855,

2 of the drawing and drop down on a light steel spring or valve 6, which when free, closes the cylinder near the bottom. The tacks enter singly one every time the driver is raised, and when the driver descends upon them they are caused to push aside the spring orvalve e, and are driven through the leather which is placed upon the punch ready to receive them, the tack always being driven through the leather before the latter iscut. tionv of the driver and the cylinder, the links 6f, 0,swhich attach the cylinder to the lever,

have the "holes which receive the pin f, connecting them with the lever, elongated to In order to insure the proper operaleave some free play for the pin and to allow the final action of the cylinder in driving the leather down upon the punch, to be efiected by a shoulder g, at the top of the driver striking it on the head. This-the driver beingfof proper length-causes the leather not to be cut till the tack is driven right through it, which is necessary, for if the leather were out first there would be nothing to hold it-during the driving of the tack through it, as there is an opening through i l the punch and bed plate for the leathered tacks to dropthrough.

The cylinder could not so well be 0on structedall in onepiece, owing to the difiiceive the tack the proper formand of inserting the spring or valve.e,' it is therefore made in two parts. The principal part E,

being turned downsmaller at the lower part to receive a shoe or foot piece it, which is bored to fit snugly over it and secured to it by a pin 2', passing through both. This enables the bottom part of E, to be made inclined on one side to receive the spring or valve 6, which consists of a piece of thin flat spring secured at its upper end to E, and also enables the opening or mouth o inthe side, to be made of proper form to receive a conductor 3', having a lip is, projecting slightly beyond the face of the cylinder.

The tacks are supplied to the cylinder by means of an inclined feeder H, H, and a divided 1, I. The feeder consists of two parallel bars placed at adistance apart sufficient to allow a tack to move freely vbetween them without its head passing through and at ,an inclination downward toward the mouth 0, in the side of the cylinder. This feeder may be of any length desired (say one or two feet). The lower culty of giving'the opening or mouth to reparts of the bars are flat transversely on their upper sides, but the higher parts m, m, of them are inclined downward toward the channel Z, between them, as shown in Fig. 4:, for the purpose when a handful of tacks is thrown carelessly upon them, of causing their points to fall into the channel. Below this upper inclined part m, m, are two openings n, n. The sides of these openings next the .channel Z, are inclined upward toward the edges of the channel as shown in Fig. 5, for the purpose of causing all those tacks which fail to fall into the channel Z, before they reach the said openings to fall through the said openings, and thus allow only those which fall into the channel to pass to the lower part of the feeder. The downward inclination of the feeder toward the cylinder terminates at a distance from the cylinder about equal to the width or diameter of the head of a tack and the remainder which extends so as to nearly touch the cylinder is horizontal in order that when the tack arrives close to the cylinder it may be upright. The face of the cylinder is filed away fiat around the mouth 0, as shown in Fig. 3 where the section is taken through the mouth. The divider consists of two flat straight edged metal tongues I, I, attached by screw bolts or otherwise to a horizontal bar J, which receives a reclprocating mot1on in guides p, p, by means of a bell crank lever K, which is actuated by a rod L, connecting it with the lever F. The tongues I, I, work in a slot in the bottom of the feeder and very near the face of the cylinder and the opening between their ends forms an oblique passage just wide enough for a tack to pass,

as shown in Fig. 3 in dotted outline. Both ends are beveled on the side next the cylinder. Every time the divider moves forward, the point of the tongue I, passes behind the foremost tack and separating it from the rest moves it toward the cylinder, but does not push it into the mouth 0, as while the divider moves forward the cylinder moves downward and carries the mouth down too low. The tack is pushed into the mouth by the tongue I, as the divider moves back while the cylinder is rising. When the tongue I, first begins to act upon the tack, the head of the tack is in contact with the face of the cylinder and the tongue acting near the point throws the point inward and gives the tack a slanting direction. The point being thus carried in beyond the projecting lip 70, is prevented slipping down outside the cylinder and the tack is compelled to enter the mouth 0.

Two tongues I, I, are not absolutely necessary to separate or divide the tacks and conduct them into the mouth of the cylinder. A single tongue arranged and having its point formed like the tongue I, would be suflicient, if it were made of greater length and the bar J, had a longer motion in order to allow it to remain in contact with the tack long enough.

The machine may be operated by an attendant working the lever F, with one hand and feeding the leather or other material used in place thereof with the other. Or the lever may be connected with 'a crank driven by any convenient motive power, and thus the attendant will have both hands at liberty to guide the material and perform such other manipulations as may be necessary.

Having thus fully described our invention we will proceed to point out what we claim and desire to secure by Letters Patent.

We claim 1. The employment substantially as herein described of a hollow cylinder with an opening in the side to receive the tacks and a driver working within it in a suitable manner to expel the tacks at the end of the cylinder and drive them into the leather or any material serving the same purpose which is presented in a suitable manner to receive them.

2. Operating the cylinder and driver substantially as described, so that the former may receive a short and the latter a long movement and that the final operation of the former to cut the leather or other material on the punch may not take place till afterment of the latter after it has driven the tack through.

3. The divider consisting of one or more tongues similar to I, I, having a straight edge working nearly close to and across the entrance of the receptacle into which the tacks are fed to be submitted to the operation of the driver, and having a beveled end terminating in a point to separate the tacks one by one as they are brought by the feeder contiguous to the aforesaid receptacle, and to conduct and push them as required into the said receptacle substantially as herein described.

4. Forming the mouth 0, ofthe barrel with a projecting lip (is) substantially as described for the purpose of passing outside the point of the tack as the barrel rises and the tack is entering the mouth, and thereby preventing the point from going down the outside of the barrel and letting the tack fall head foremost into the barrel.
