KARL WINTSOH, JR, OF NEWARK, NEW JERSEY.
SPECIFICATION formingpart of Letters Patent No. 757,166, dated April 12, 1904.
Application filed July 1,1902. Serial No. 113,981. (No model.)
To all whom it may concern: Be it known that I, KARL WINTSOH, Jr. a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Bone -Holding Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to figuresof reference marked thereon, which form a part of this specification.
The objects of this invention are to provide a device which can be afiixed to a butchers block or bench and serve to hold a bone while being sawed up, to enable the bone to be held firmly and rigidly, so that it can be quickly sawed without danger of injuring either the operator or the saw, to thus save time, facilitate sawing the bone into very thin disks, and to obtain other advantages and results, some of which may be referred to hereinafter in connection with the description of the working parts.
The invention consists in the improved butchers bone-clamp and in the arrangements and combinations of parts of the same, all substantially as will be hereinafter set forth, and finally embraced in the claim.
Referring to the accompanying drawings, in which like figures of reference indicate corresponding parts in each of the several figures, Figure 1 is a side elevation of my improved device as mounted on a bench; and Figs. 2 and 3 are cross-sectional views of the same, taken on line m, Fig. 1, and looking toward the right and left, respectively, in said figure. Fig. 4 is a side elevation of the device, partly in central vertical longitudinal section, and also showing in outline the adjustable jaw-carrier relaxed; and Fig. 5 is a cross-section on line y, Fig. 4.
In said drawings, 2 indicates a cast-iron bar provided at opposite ends with feet 3 4, adapted to receive screws 5, and by which said bar may be firmly mounted on a bench or block, the said feet 3 4 holding it up away from the bench a little distance and parallel to the same. At one end of said bar 2 and cast integral therewith is an upwardly-projecting rest or stop 6, curved at its face 7 next the bar, so as to approximately fit against a bone, and having said face 7 corrugated or toothed, as at 8, in order to more firmly engage a bone. The bone to be sawed, it will be understood, is disposed transversely of the bar 2 and above the same, with its side against the rest 6. To engage the opposite side of the bone and clamp the same firmly against the said rest 6, I provide an adjustable member 9, also curved at its contact-face 10 to approximately fit against a bone, and having teeth or corrugations 11. This member 9 is at its lower end recessed or bifurcated, as at 12, to receive the upper edge of the bar 2 as a guide to hold the member against rotating. Said adjustable member is mounted loosely upon the reduced end 13 of a screw 14, disposed parallel to the bar 2 and working in a threaded socket or perforation of a carrier 15, slidable on said bar. In operation when a bone has been placed in position against the rest 6 the carrier 15 is slid up 'to bring the clamping member 9 into contact or approximately into gripping position, The screw 14 is then tightened up by turning and the member 9 forced tight against the bone to firmly clamp the same.
The bar 2 is made long enough so that my improved device will receive bones of different sizesrbut by the construction described only a few turns of the screw are needed to clamp any bone, since the sliding carrier 15 does most of the adjusting. Thus there is no time lost in putting in a bone to be sawed.
Said sliding carrier 15 may be of any suitable construction common in the art and adapted to my purpose, as described; but I have shown in my drawings the particular construction disclosed in United States Patent No. 640, 500, issued January 2, 1900, to James L. Taylor. This carrier is apertured, as at 16, to receive the bar 2, and has at the forward end of its lower side and the rear ,end of its upper side transverse-toothed blocks 17 to normally bite into the bar under the expansive action of the spring 18 or the strain of tightening the screw 14 against a bone. Upon tilting the carrier, as shown in outline in Fig. 4, it can be slid into any desired adjustment, all as is fully set forth in the patent above referred to. To enable the carrier 15 to be put in place upon the bar 2, said bar is made in two sections, the joint preferably being close to the foot 4:, farther from the fixed rest 6. The sections are held together by a rivet, bolt, screw, or the like, as at 19, after the carrier is mounted.
By my construction thus described I provide a device which can be cheaply put upon the market, and when rigidly mounted on a butchers bench or block will enable him to quickly and easily saw a bone into as thin pieces or disks as desired without any danger of accident.
Having thus described the invention, what is claimed as new is The herein-described butchers bone-clamp, comprising opposite end feet 3, 4, and a raised bar 2, extending between said feet, an integral upwardly-projecting stop or rest 6, at one end of said bar, curved at its inner face to fit against a bone and being corrugated, a sliding carrier surrounding said bar and adapted to be set at any desired point thereon, a clamping-screw working in said carrier and a clamping member 9, loosely mounted on the end of said screw and presenting to the rest 6, a correspondingly curved and corrugated grippingface, said feet having means for attachment to a bench or the like and forming stops to prevent inadvertent removal of the slide from the bar, and one of said feet being detachable to permit removal from the bar when desired.
In testimony that I claim the foregoing I have hereunto set my hand this 17th day of June, 1902. I
