MACHINE FOR GRINDINGl HORSESHOE-CALKS.
SPECIFICATION formngpart of Letters Patent No. 417,532, dated December 17, 1889.
` Application filed .Tuly 13, 1889. Serial No. 317,491. (No model.)
to the accompanying drawings.
This invention relates to new and useful improvements in machines for sharpening horseshoe-callzs.
The invention consists in' the peculiar construction of a machine vhaving a grindingwheel and mechanism to drive the same adapted to be attached to a horseshoe while upon the foot of a horse, and means for tilting the machine to place the grinding-wheel at the desired angle to the calk; further, in the peculiar construction of the device for feeding the grinding-Wheel to its work; further, in the peculiar construction of the clamp attached to the horseshoe and of the clamp for securing the frame of the machine to the shoe-clamp, and, further, in the construction, arrangement, and combination of the various parts, all as more fully hereinafter described. p
, In the drawings which accompany this specification, Figure l is a perspective view of my improved machine as in use with some of the parts detached. Fig. 2 is a side elevation thereof. Fig. -3 is an end` elevation thereof, looking toward the grinding-wheel, which is shown in dotted lines. Fig. 4 is a cross-section on line a: in Fig. 2. Fig. 5 is a vertical central section, partly in elevation, of the shoe-clamp and frame-clamp.V Fig. 6 is a plan of the shoe-clamp. Fig. 7 is a top plan of the frame-clamp. Fig. 8 is a section thereof on line a a in Fig; 7.
A is a rectangulary frame, having a detachable top or cap A secured by boltsV or rivets o.. The sides of this vframe have the slots B, preferably extending the entire'length of the frame, and in these slots are secured the 'sliding bars B, having suitable side grooves b, engaging into the sides of the slots B. The
upper ends f these bars are cut away to form the bolts c, which pass through the cap and are'provided at their upper vend with suitable screw-threads to receive a nut c', by
which the bars may be adjusted up or down, springs CZ` being sleeved over the bolt below the cap, bearing with their lower end against the shoulders d on the bars. The shaft C is j ournaled in the upper end of these bars, carrying at one end the gear-wheel C', having the handle C2, and at the other end the handle O3. This wheel Ineshes with the sliding 6o pinion D, secured upon the shaft D,Wl1ich is journaled in the lower ends of the bars B', carrying at the other end the grinding-wheel, preferably an emery-wheel. The pinion D has a sufficiently wide periphery to admit of its being kept in engagement with the gearwheel in any of its adjusted positions.
E is a collar secured upon the shaft D', having the groove e, in which the lever f engages, this lever being fulcrumed in one of 7o the notches g in the cross-bars g of the frame, and adapted to move the shaft with the grinding-wheels acting against the spring g, sleeved upon the shaft. y
E is a tilting-foot pivotally connected to the base of the frame by the bolt g3 at one side, and at its free end provided with the upwardly-extending arm h, which may be vertically adjusted ,by the screw-threaded h is supported in the bearinoth3 in the cap, and the arm h is held from lateral displacement by the set-screw t' engaging in the slot t" in the frame. j
v4F is the shoe-clamp, having the rack-bar F', 85 provided with the slot F2 and the clampingjaws G G. The clamping-jaw G is pivotally connected to the stationary pin j, while the jaw G is secured to the sliding pin j', which is pivotally secured to the slide jg.
H is a sliding spring-catch, having the pin k, carrying the cross-bar lc', which is held in contact with the teeth of the rack-bar by the Aspring 7c in the casing 7c3. The arm lof the casing carries the cam Z, having a suitable 95 handle Z. The spring-catch being in suitable proximity to the jaw G when engaged upon the shoe of the horse, as shown in Fig. l', allows of tightly clamping it thereon by jaw G.
The frame of the machine is secured to the shoe-clamp by means of the bolt I, which is slidingly secured in the slot F of the rackbolt h', having the crank-handle 71,2. The bolt 8o turning the Cain-lever to bear against the Ioo bar by means of the groove m, and passes upward through the frame of the machine through the slots m 911.29713 in the hinge-piece, the bottom, and top, respectively, of the frame.
The bolt is provided at the top with a clamping device J, for clamping the machine-fran'le iirmly to the shoe-clamp.
Of the following description, o is the clampplate, having a suitable aperture for the bolt, and a slotted extension o', in which the body of spring-catch o2 is engaged by means of the set-screw p engaging in the slot. p is the spring-dog, having suitable teeth to engage into the upper rack-bar on end of the bolt I. q is a double cam pivoted to the body of the spri11gcateli,a1nl provided with the handle q', all so arranged that by turning the handle q into a vertical position, as shown in Fig. 2, the dog being engaged with the bolt, the cams bear down upon the plate o and lift the bolt I, thereby firmly clamping the frame to the shoe-clamp.
The parts being` thus constructed and arranged, they are intended to operate as follows: The operator clampsthe device upon the horses shoe, as shown in Fig. l, by means of the shoe-clamp, the jaws G and G bearing upon each side of the shoe and being held tightly in position by means of the cam-levers Z. The clamping device at the top of the bolt I being loose, it is evident that the frame of the l .machlne is free to turn in any direction, be-
ing pivoted upon the bolt I. The operator adjusts the frame of the grinding-wheel in proximity to the calli which he desires to sharpen, tilting the frame by means of the tilting-foot E,moving it up or down by turning the crank h until the grinding-wheel assumes the angle at which he desires to sharpen the ealk. Then by pressing do\vn' ward upon the handle of the spring-catch o he adjusts the catch to the desired point to allow of bringing the double caln q into operation, turning it into the vertical position, as shown in Fig. 2, thereby clamping the frame in its adjusted position firmly to the shoe-clamp. The operator then revolves the gear-wheel C with one hand and with the other presses upon the outer end of the lever f, whichvis fulcrumed in the notch g, as before described, thus feeding the grinding-wheel up against the calli to the desired degree, the side of the grinding-wheel grinding the side of the calk, the operation being continued until the desired object is accomplished. Should the wheel in any Way become caught or clogged against the calk, the springs d will yield, and thereby prevent any damage to the wheel. When one call: is finished, by releasing the cam q the frame may be turned around to operate upon the other calks of the shoe without detaching it, and may be slid along and adjusted in the desired relation to such calk, again clamped in position, and the operation repeated. The pinion D is made with a periphery of sufficient width to allow of feeding the shaft D', on which the pinion and the grinding-wheel are journaled, backward and forward without becoming disengaged 'from the gear-wheel C. lVhen the operation is completed, the operator has simply to turn the cam-lever L, thereby loosening the clamp from the foot, and the whole machine may be at once taken off. In case the horse becomes unruly the operator can thus detach the machine without delay, so that there is no danger of its becoming damaged or of injury to the horse.
Vhat I claim as my invention is-v l. In a machine for grinding horseshoecalks, a slice-clamp consisting of jaws secured to a slotted ifaelebar, a grinding-frame pivotally secured thereto by means of a clamping-bolt slidingly engaging in the slot of the rack-bar, and means, such as the tilting-foot E', for tilting the frame, substantially as described.
