CHARLES F. PRESTON, OF CHICAGO, ILLINOIS.
TOOL-HOLDER.
SPEGEFICATION forming part of Letters Patent No. 699,708, dated May 13, 1902.
Application filed July 25,1901- To all 1072,0772, it may concern:
Be it known that I, CHARLES FRUIN Pens- TON, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented a new and Improved Tool-Holder, of which the following is a full, clear, and exact description.
The object of the invention is to provide a new and improved tool-holder especially designed for use in lathes, planers, and other metal-working machines and arranged to adjustablyhold a cutting-tool with an even bearing on the top and bottom to prevent undue vibration and render the tool as solid as an ordinary forged-steel tool.
Another object of the invention is to adjustably hold the tool in the holder without the use of set-screws or other objectionable projections liable to interfere with the proper handling of the tool in the machine.
Another object of the invention is to provide a tool having no projections to interfere with the tool being removed or replaced in the tool-post.
The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.
A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.
Figure 1 is a side elevation of the improvement. Fig. 2 is asectional side elevation of the same. Fig. 3 is a plan view of the same. Fig. 4 is a transverse section of the same on the line 4 4 in Fig. 1, and Fig. 5 is a similar view of the same on the line 5 5 in Fig. 1.
The improved tool-holder consists, essentially, of ashell or casing A, in which is mounted to move a locking-slide B, adapted to lock a cutting-tool O in position in the casing or shell A at one end thereof, with an even bearing on the top and bottom of said cuttingtool. The slide B fits snugly in the opening A of the casing A, with the exception of the front end, which is somewhat reduced, and formed on the top with a bevel B, extending inwardly and downwardly, as is plainly indicated in Figs. 1 and 2. On this bevel rests the under side of the cutting-tool O, which Serial No. 69,704. (No model.)
engages with its top a bevel A corresponding to the bevel B and formed on the upper wall of the opening A, as is plainly shown in Figs. 1 and 2. It is evident that when the cutting-tool O is placed on the slide B at the bevel B thereof and atthe time when the said slide B is in an outermost position, as shown in Fig. 2, then upon driving the slide inward the tool 0 is forced upward by the bevel B against the bevel A so that the tool 0 is se curelylocked in position in the holder between the two bevels B and A of the slide B and the casing A. IVhen this has been done,a set-screw D, screwing through the top of the casing A against a bevel B in the slide B, serves to lock the latter in an innermost looking position. (See Figs. 1 and 5.) The head of the set-screw D extends into a recess in the top of the casing A, so as not to project from the same. The casing A has a crosssection corresponding approximately to that of the ordinary forged-steel tool and is, like the latter, set and fastened in the tool-post or other device ordinarilytemployed for carrying the tool.
By the arrangement described the tool 0 is adjustably held in the holder and an even bearing is had on the tool, so as to prevent undue vibration, and thereby render the tool as solid as an ordinary forged-steel tool.
Having thus fully described myinvention, I claim as new and desire to secure by Letters Patent 1. A tool-holder, comprising a casing, a slide movable in said casing and adapted to project at its forward end therefrom, the said forward end of the slide being reduced and formed with a beveled top for engaging the tool and pressing the same against a correspondingly-beveled wall of the casing, as set forth.
2. A tool-holder, comprising a casing, and a slide having a rectangular body portion fitted in the opening of the casing, the forward end of said slide being reduced and the top of said reduced portion being beveled in ward and downward, opposite 2. corresponding bevel in the top wall of the casing, the said reduced end of the slide being adapted to be moved into an outermost position to permit of theinsertion of a tool between said beveled surfaces, as set forth.
the casing, and a set-screw screwingin the casing against the bevel on the slide, to lock the latter in place after adjustment is made, as set forth.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
CHARLES F. PRESTON.
