COMBINED TOOL.

SPECIFICATION forming part of Letters Patent No. 399,297, dated March 12, 1889.

Application filed May '7, 1888.

To aZZ whom it may concern Be it known that I, GEORGE H. TUCKER, a citizen of the United States, residing at Brownville, in the county of Piscataquis and State of Maine, have invented a new and useful Combined Tool; and I do hereby declare that the following is a'full, clear, and exact description of the invention, which will e11- able others skilled in the art to which it appertains to make and use the same.

My invention relates to a convenient combined tool for farriers, jobbing blacksmiths, and others. It is recognized as a horseshoenail clincher, pipe, nut, and bolt wrench, and witha cutting attachment answers the purpose of a pipe-cutter.

It has been noticed that horses generally dread the last operation in shoeingthat is, the clinching or turning over of the projecting ends of the nails with a hammer. This necessitates the beating and denting of the upper part of the hoof, which in a great many animals is quite thin, and any pounding upon it would naturally hurt and in a great many cases lame the horse for some time. In very nervous horses and colts this proceeding is attended with much difficulty, as the uninitiated animal soon becomes almost unmanageable through fear, and it is to provide an instrument that will quickly and easily turn and clinch these nails in a neat and perfect manner without jarring, battering, or in any way hurting the hoof, and one that will also serve as a handy tool for various other purposes, that Ihave invented my device, which is illustrated in the accompanying drawings, in Wl1lOl'l-- Figure 1 shows an elevation of my combined tool in the act of clinching a nail in a horses hoof. Fig. 2 is an elevation of my combined tool in position for turning a common bolt-nut. Fig. 3 is a side elevation of the pipe-cutting attachment, which is used in place of the upper jaw of my device. Fig. 4:

jawof my device, showing serrations upon. its upper surface. Fig. represents an isometric view of the pipe-holding jaw used with my. device.

In Fig. 1 of the drawings, A represents the upper handle or lever, the lower part of which is bent to the form of a compound reverse curve, A small hook-shaped cam, 9, projects laterally from the lower end of this handle, and two flat parallel plates, (:1 (I, are welded to and extend downward or longitudinally each side of the said end at the base of the cam 6. Holes 1' are drilled through the extending plates (Z (1, near their projecting ends, and furnish means whereby the handle A is pivotally connected with the rest of my device, as will be hereinafter explained.

The lower handle or lever, B, is constructed from a round bar of metal having one end flattened and formed into the eccentric cam C. For convenience in using this handle B it is bent or curved upward from the cam a short distance, then extends outward in a straight line tangent to the curvej ust formed.

The two handles A and B are connected to each other by means of the connecting or parallel guide-bars R R, which consist of two small square bars of metal from one-fourth to three-eighths of an inch thick and about four or five inches long. The upper end of these bars R R are bent at a right angle and the two angular parts welded together, forming the cross-piece P, thus leaving a narrow longitudinal slot, M, between the two sides. This slot M is of sufficient width to admit the cam C on the end of the lower lever, B, and a pin passing through the holes 0, drilled through the free ends of the guide-bars R R, pivotally connects the cam C to the bars and allows the working of the said cam in a vertical direction.

The upper ends of the guide-bars R R have extending from the cross-piece P two vertical projecting lugs, f f, situated a suiiicient distance from each other to just fit between the extending plates (1 d on the upper handle, A. These lugs f have their corners rounded and form part of a hinge. A hole, 0, drilled through the center of each, permits them to be pivotally connected to the upper handle, A. The upper end of the guide-bars R R also IOC have pivoted thereto and projecting laterally therefrom the upper serrated jaw, F, which consists of a solid piece of metal (preferably steel) about five-eighths of an inch wide and one and one-half inch long. One end of this piece is shouldered or cut away from each side, leaving a projecting lug, f, extending from its center. The corners of this lug are rounded and a hole drilled through its center, and it is made of a sufficient size and thickness to fit between the lugs f f, projecting at the upper end of the guide-bars R R.

The upperv surface of the jaw F is made irregular in shape, and is cut transversely in the form of an irregular curve, the free end of which projects over this concavity in the form of a horn,j. The under side of the jaw F is planed straight at right angles with its sides, and contains serrations or teeth to prevent the jaw from slipping when used. The peculiar shape of this upper jaw is necessary for the various positions in which it is used. One end of the jaw' is pivoted or hinged to the lower end of the upper handle, A. The cam 6 extends into the concavity, and the horn j, projecting over the end of this cam, prevents the jaw F (when not in use) from dropping out of place below the cam, and also more readily facilitates the placing of the same in position, as will be hereinafter described.

Sliding upon the guide-bars R R above the lower cam, C, is a metal band or casing, D, mortised to fit the bars, and having a partition, if, between said mortises, fitting the slot M between the two guides R R. Latcrally projecting from one side of the case D, at right angles from the plane of the guide-bars R and in an opposite direction from the lower handle, B, is a fiat shelf, I, the upper surface of which is notched or roughened to prevent the same from slipping when used. This projecting shelf I forms the lower jaw of my device.

The cam C on the lower lever, B, operates the lower jaw, I, raising it upon the guiderods R R, and a spring, S, (shown in Fig. 5,) situated between the two guides R R and pressing upon the partition if in the casing D, returns the jaw I to its normal position after the releasing of the lower lever, B.

My invention is used for clinching horseshoe-nails, as follows: The lower jaw, I, is placed under the horses hoof upon the head of the nail to be clinched, as shown in l. The upper jaw, F, is placed upon the protruding end a of the nail by means of the upper handle, A, the cam e holding the jaw F in position and also furnishing the leverage for this partof my device. It can now readily be understood that by pressing down upon the lower lever, B, the cam C will act upon the under side of the lower jaw and force the latter up against the head of the nail, at the same time drawing down the guide-rods R with the connected upper jaw, F,"which, owing to its angular tilt, presses outby bringing the upper handle, A, over until the upper jaw, F, is parallel with the projection of the lower jaw and. operating the lower handle, 13, the tool can be made to fit numerous sizes of nuts or round pipe, and, as it is self-adjusting, it has quite an advantage over a monkey-wrench for this purpose.

My combined tool can also be used for a pipe-cutter in the following manner: The upper jaw, F, is taken out and a similar jaw, F, containing a rotary steel cutter, (shown in in Fig. 3,) substituted in its place. The cutter-holding jaw F is made the same proportions as the upper serrated jaw, F, the only difference being that the former has a slot cut longitudinally through its center from its under surface, into which a circular steel cutting disk or wheel, h, is inserted and pivoted thereto by a pin, p, passing through a hole drilled through the sides of this upper jaw.

The lower jaw, l, of my device is taken off from the guide-bars R and a similar but hookshaped jaw (shown in Fig. S) substituted. This substitute jaw consists of the casing D, having the central partition, if, constructed to fit the guide-bars R R. A laterally-proj ectin g shelf or jaw, M, having its outer end curved upward, extends from one side of the casing D, an d this projecting shelf M is curved upward in order to more firmly hold the pipe while cutting.

It can now be readily understood that with the curved lower jaw in place of the straight one formerly described, and the upper jaw provided with a cutting-disk revolving there in, my combined tool would be operated in cutting round pipe in the same manner as when turning a nut, as shown in Fig. 2.

Having thus described my invention, what I claim, and desire to secure by Letters Patout, is

1. A tool. consisting of the combination of the upper handle, A, with projecting cam e and hinge (Z, the guide-bars R R, and serrated upper jaw, F, pivotally connected with said upper handle, the casing D, with laterallyprojecting shelf or jaw I, and the lower handle, B, with cam 0, operating the casing D and jaw I, substantially as shown and for the purpose described.
