CHUCK.
SPECIFICATION forming part of Letters Pat-ent No. 262,869, dated August 15, 1882. Application filed October 25, i881. (No model.)
To all whom it may concern Be it known that I, JOSEPH `WERTHEHM, of Frankfort-on-the-Main, Germany, have invented a new and ImprovedChuck, of which the following is a full, clear, and exact description.
The object of my invention is to provide a new and improved chuck which grasps and holds rods or tools very rmly, and is simple in construction and operation.
The invention consists in the combination, with the stock, of the radially-slidin g jaws, the longitudinallysliding sleeve, the studs, the ring, andthe pivoted lever, as hereinafter described.
In the accompanying drawings, Figure l is a longitudinal sectional elevation of my improved chuck. Fig. 2 is a crosssectional elevation of the same on the line mx, Fig. 1. Fig. 3 is a cross-sectional elevation of the same on the line y y, Fig. l. Fig. 4 is a longitudinal sectional `elevation of a `modification ot' my improved cli'uclr. Fig. 5 is a cross-sectional elevation of the same on the line w w', Fig. 4. Fig. 6 is a cross-sectional elevation of the same on the line y y', Fig. 4.
Similar letters of reference indicate corresponding parts.
The tubular stock A is provided at one end with a series of radially-sliding'jaws, B, having concaved inner ends, and having their outer ends beveled downward from the end ot' the stock. A spring, O, is passed into the outer end of each jaw, and these springs, which are attached to' the stock A in suitablerecesses, D, ofthe same, serve to draw the jaws outward. A sleeve, E, surrounds the stock A and is guided to slide longitudinally on the same, and also to revolve with the stock. A
ring, F, fits 'loosely in an annular groove in one end of the sleeve E, so that the sleeve can revolve in this ring F,which is pivoted between the ends of the fork Gr of a lever, H,
suitably pivoted at J. As many screw-studs K as there Vare jaws B in the chuck are contained in radial bosses L on the outer end of the sleeve E, which bosses are so located that the rounded inner ends of the studs Krest on or on a line with the outer ends of the jaws B. The studs K can be so adjusted by means of nuts M on their outer ends that their inner ends will project more or less from the inner surface of the sleeve E. The sleeve E is made very thin, so as to be elastic, and this sleeve does not tit closely on the stock A, but is provided with internal projections, N, resting on the surface of the stock A.
VIn the modification shown in Figs. 4, 5, and 6 the outer ends ot' the jaws B are :not beveled and the studs K do not pass through bosses of the sleeve, but pass through the outer ends of spring-strips O, provided at the inner ends with a lug, P, resting against the inner ends ot' the recesses D inthe stock A. The upper edges ot' these spring-strips have a bevel from the outer' end downward at or near the middle. The sleeve E in this case is not elastic, and is much narrower than the sleeve E, but is also surrounded by the ring F, pivoted in the fork G at the upper end of the lever H. The studs K need not 'necessarily be screw-studs, but can be held in the bosses L by other suitable devices.
The operation is as follows: The rod Q, tool,
'0r other object to be held by the chuck is passed into the longitudinal aperturellt of the stock A, as shown. By operating the leverH the sleeve E is pushed toward the outer end of the stock A, as indicated by the arrow a. The studs K will slide up the beveled outer ends of the jaws B and will press these jaws radially against the rod Q or other object in the stock, as shownin Fig. 1. 1f the rod Q is to be released, the leverHis operated to draw the sleeve in the inverse direction of the arrow a', whereby the studs K will be removed from the jaws B, which are dra-wn outward a short distance by their springs C.
The operation of the modification shown in Figs. 4, 5, and 6 is similar. The sleeve E slides up the bevel of the spring-strips O and thus depresses the outer ends of these strips, thereby pressing the jaws B against the rod Q. The collar Storms a check to prevent the sleeve E or E from being drawn too far in the inverse direction of the arrow a.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
In a chuck, the combination, with the stock A, of the radially-slidingjaws B, the sleeve E, the studs K, the ring F, and the pivoted lever H, substantially as herein shown and described, and for the purpose set forth.
JOSEPH WERTHEIM.
