TOOL-HOLDER.
SPECIFICATION forming part of Letters Patent No. 478,943, dated July 12, 1892.
Application filed September 22, 1890. Serial No. 365,846x (Model.)
To all whom it may concern:
Be it known that we, GEORGE REHFUSS, MARTIN O. REHFUss, and JOHN G. REHFUss, citizens of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Tool-Holders, which improvement is fully .set forth in the following specification and accompanying drawings.
Ourinvention consists of a novel tool-holder having a sleeve adapted to hold the shank of a tool and to be compressed by contact with an inclosing casing.
It further consists of the combination of parts hereinafter set forth.
Figure 1 represents a central longitudinal section of a tool-holder embodying our invention. Fig. 2 represents a view of a portion of the compressible sectional sleeve, the inclosing case being in section. Fig. 3 represents a view of the same part-s, the sleeve and case being in different relative positions from those shown in Fig. 2. Fig. 4 represents a perspective view of the operating-spindle. Fig. 5 represents a modification of part of the device.
Similar letters of reference indicate corresponding parts in the several'iigures.
Referring to the drawings,'A designates a tool-holder having an outer shell or casing B with a tapering or conical end B. Within the shell B is an inner casing C, adapted to be revolved in said shell, which is secured therein by a screw-cap D, so as to prevent any longitudinal movement of the same.
NVithin the casing C is a compressible sectional sleeve E, corresponding in form to the inner face of the casing and consisting of the parts F and G, each extending longitudinally and having tapering ends F G. The said sections, which are normally separated longitudinally, are provided at intervals with enlarged portions H, adapted to contact with the inner face of the casing C, the other parts of the surface thereof between said portions H being free from contact with the said casing, so as to lessen the friction in operating the device. The sections have sockets H,
adapted to receive the shank of the tool, the said shank passing through openings in the ends of said shell and casing into said sockets. One end of each of the sections F G is connected with a head H2 by a pin J passing through an opening in the sectionand ent-ering the head, the pin being ofsuch diameter as to permit a slight movement of the sections on the said head.
Fitting in one end of the casing C and adapted to slide therein is a head K, having a spindle L, which operates in a sleeve M, passing through an opening in the cap D. Pivotally secured to the inner face of the casing C is one end of the member N of a togglelever, the other member P being pivoted to the head H2. Forming a part of thehead K and within the casing C is a piece Q with the sides R and a cross-piece S, the latter having an inclined under face adapted to contact with the outer part of the jointed end of the member N of the toggle-lever, and a connecting strip or neck T, having its forward end or portion between the sides R provided with an inclined face U, adapted to contact with the opposite side of the front end of the said member N from that contacted with by the crosspiece S.
To prevent the withdrawal or separation of the sleeve M from the device, the outer end thereof is enlarged and provided with an annular groove V, in which is located a collar X, secured to the spindle L by means of screws Z, which are inserted into said collar and spindle through openings Yin the sleeve, the heads of the screws being flush with the periphery of the collar, so that they do not interfere in the rotation of said collar and spindle within the sleeve.V
The manner of operating the device is as follows: The parts beingA in position, as in Fig. 1, the shank of the tool is inserted in the openings in the smaller end of the shell and casing and the spindle is drawn back, so'that the inclined under face of the cross-piece S comes in contact with the outer end of the member'N, forcing the latter, and with it the member P, in such direction that the lever is opened, and the end of the said member P, which is pivoted to the head H2, is pushed along with the said head and the sections F G connected therewith toward the smaller end IOO of the casin g, where, owing to the tapering or conical form ot the said casing, the ends of the sections in contact therewith are pressed closer together, thereby clamping the tool, so that the same is firmly held in place. To release the tool, the spindle L is pushed in, so that the inclined face U of the neck T, engaging the member N of the toggle-lever, closes the lever, the cross-piece S having previously passed over the said lever, so as to be out of the way of the joint thereof. As the said toggle-lever is being closed, the head 112, with the sections F G, are drawn away from the smaller end of the casing, so as to release the pressure of the said sections on the shank, and thereby permit the release of the tool.
In the modification shown in Fig. 5 a coilspring V is inserted between the end ol` a stem on the head ll2 and shouldered portions of the sections F and G, thereby adapting the movement of the sections, so as to permit the insertion in the sockets of shanks of diil'erent diameters and tightly hold and clamp the same therein, the tension or grip being uniform in each case, whether the diameter of the shank is larger or smaller.
Having thus described our invention, what we claim as new, and desire to secure by Let ters Patent, is-
l. A tool-holder having a casing with a tapering or conical end, a head movable in said casing and having secured thereto a sleeve with tapcrin g ends, a toggle-lever having one end pivoted to the casing and the other to the head, and mechanism, substantially as described, or operating said toggle-lever, said parts being combined substantially as dcscribed.
2. A tool-holder having a casing with a tapering end having an opening therein, a head movable in said casing and having a compressible sleeve secured thereto, a toggle-lever pivoted to the casin g and head, and a spindle with mechanism attached thereto, substantially as described, for opening and closing said toggle-lever, said parts being combined substantially as described.
3. A tool-holder having a easing with atapering end having an opening therein, a head movable in said easing, a compressible sleeve connected with said head, a toggle-lever pivoted to said head and casing, a spindle with a cross-piece adapted to contact with the said lever, so as to open the same, and means, substantially as described, connected with the spindle for closing said lever, said parts being combined substantially as described.
Il. A tool-holder having a casing, a compressible sleeve within said casin g consisting ot' sections, a head connected to each of said sections by pins passing through enlarged openings in said sections, and mechanism pivotally connected with said head and casing for closing said sleeve, said parts heilig combined substantially as described.
5. A tool-holder having a casing, a compressible sleeve Within said casing formed ol. longitudinal sections, a head connected with said sections, a toggle-lever pivoted to said head and casing, a head with a spindle, anda strip or neck secured to said last-mentioned head and having an inclined front portion adapted to contact with one side of a member ot the said toggle-lever, said parts being combined substantially as described.
G. A tool-holder having a casing, a spindle therein provided with a sleeve having an enlarged portion with an annular groove therein, acollar on said spindle within said groove, and screws securing the collar to said spindle, said sleeve having openings in its sides for the passage ol' said screws, said parts being combined substantially as described.
