TOQL-HOLDER FOR BUTTON-{HITTING MACHINES, 800.
SYEGIFICATION forming part of Letters Patent No. 485,147, dated October 25, 1892.
Application filed April 19, 1892.
To all whom it may concern.-
Be it known that I, FRANCIS E. BECKWITH, Jr., a citizenof the United States, residing at Springfield, in the county of Hampden and vision of improved devices for the reception and retention of the tool, the same being capable of readily permitting the adjustment of the tool, and in general to improve the construction and increase the utility of the holder, all as will be hereinafter rendered apparent.
To these ends the invention consistsin con structions and combinations of parts, as hereinafter described, and set forth in the claims.
Reference is to be had to the accompanying drawings, Figure 1 being a side elevation of a form of machinedesigned for cutting or turning buttons or other round cbjects- Fig. 2 is a side elevation, on an enlarged scale, of the tool-holder and a tool therein. Fig. 3 is an elevation of the same as seen at right angles to said view, Fig. 2. Fig. 4 is a sectional view of a part of the holder, taken on line i 4, Fig. 3. Figs. 5 and 6 are perspective views of the parts which together constitute the improved toolholder.
Similar letters of reference indicate corre sponding parts in all of the views.
A represents a tool-holder, the same being shown as mounted upon the extremity of a reeiprocatory tool-holder 'bar B, adapted to have movements toward and from the rotary chuck C by means of the hand-lever D and weighted retiring-lever E. This is to be understood as merely one of various manners of mounting the tool-holden The tool-holder body d which is to be constituted. by a suitably-formed block ofsteel or iron, has within one .face thereof a'groove a, the width of which is slightly greater than the-combined thickness of the tool a; and the gib b, the direction thereof being such that the tool seated in the groove therefor has its length suitably angular to the plane of r0 Serial No. 429,710. (No model.)
tation of the part to be turned or cut,as customary in this class of machines. The toolholder body has transversely through 1t and ill proximity to the said groove a bore or socket f, which, as seen at f, is of an enlarged transverse area, which merges into the said groove, and a spindle g has its shank portion g fitted for rotation in the said socket f. The spindle comprises an enlargement it nextto the shank, which is of cam form, as clearly indicated in the drawings, and which cam-formed enlargement has its disposition within the suitably.- enlargedportion of the before-mentioned. socket which merges into the said groove. The spindle g has a suitable extent laterally from the face of the holder-body and is provided. for'c'onvenience'ot turning it, with the arm g The spindlehas itssaid shank g, which is entered farthest within the socket, as aforesaid, peripherally grooved,as at g for rece ving the engagement therewith of theretaini ng stud or screwt', all whereby the spindle 1S freely rotatable but incapable of endwisemw tion. The said gib at each end is prov ded with an angular lug 1), extended oppositely from the tool 00, to overlie and engage the tool-holder body at portions thereof next to the ends of the groove a, whereby anvtendency for endwise movement of the gib 1s pre vented, it being, furthermore, retained by the screw j passing transversely through the tool-holder body and with a screw engagement into the gib at a portion thereof near its one end. I As. manifest, on turning the spindle in theproperdirection, the prominent portion of the cam has a confining engagement upon the gib to force it transversely of 'the groove, and, exerting a force to bind the tool against the opposite border of the groove, effectually holds it as one with the tool-holder. The provision of ,the gib is advantageous, as it constitutes a distributing medium for the binding force 'imparted by the cam throughout a greater area than would be the case were the gib dispensed with and the cam caused to bear directly upon the tool.
An operative device within the scope of the present invention would be constituted by the lastcontemplated omission of gib and directcoacting relations of the spindle-cam with gagement and-the farther end thereof,capabilities for deflection by reason of its spring nature, so that when crowded by the cam extended areasthereof are in bind against the tool.
The employment of stool-holder substantially such as above described is unusually advantageous, especially in a machine wherein a very hard medium is to be worked upon, for the reason that consequent upon the frequent grindin gs of the tool its resetting is ne- 'cessi'tated, and this, it will be perceived, may
performed with the' utmost facility and co lerity. r
Having thus described my invention, what I claim, and desire to secure by LettersPatent,'is-- L- The combination, withaholder-bodyhavinga tool-receiving groove a extended along and within one side-thereof and the socket f extended transversely within the body adjacent the groove, which has an enlarged section or area f that merges intothe groove, as described, of a spindle g, having a shank fitted to turn within the base of said socket and having the cam-formed section h, which is within said socket enlargement,and a suitable extension whereby the spindle may be turned and the tool m,adapted to be set with- .in' said groove and to have a sidewise binding pressure imparted thereto by said cam, substantially as described. v v e 2. The combination,withaholder-body havingia tool-receiving groove a extended along and within one side thereof and the socket f extended transversely within the body adjathe groove, which has an enlarged sec- 't-ion onarea f that merges into the groove,
as described, ora spindle g, having a shank in-the body adjacent the groove, which has an enlarged section or area that merges into the groove, as described, of a spindle having a shank provided with the peripheral groove and fitted for a rotational movement and having the cam-formed section h disposed within said socket enlargement, and a suitable extension whereby the spindle may be turned,
the stud v1 penetrating the body and engaging said peripheral'groove of the spindle; and the tool adapted to be set within said receivinggroove and'to have a binding pressure im-' parted thereto by said cam,substant-ially as described.
4. The combination, with a body having a -,tool-receiving groove a extended along and within one side thereofand the socket f extended transversely within the body adjacent the groove-and having the enlarged section or areaf, of the spindle fitted to turnv in said socket and having the cam-formed section h next to the groove, the tool and gib 12 within the groove, and a screw passed through aportion of the body between its sides and transversely engaging the gib near one end thereof, substantially as described.
