D. E. WHITON, OF WEST STAFFORD, CONNECTICUT.
IMPROVEMENT IN CHUCKS.
Specification forming part of Letters Patent N0. 58,704, dated October 9, 1866.
To all whom t may concern:
Be it known that I, D. E. WHITON, of West Stafford, in the county of Tolland and State of Connecticut, have invented a new and useful Improvement in Lathe-Chucks, and I do hereby declare that the following is afull, clear, and exact description thereof, which will enable others skilled in the art to ina-ke and use the saine, reference being had to the accompanying drawings, forming part of this speciiication.
The present invention relates to that class of lathe-chucks commonly known as scrollchucks, and it consists in forming the pinion-wheel and its arbor or shaft ot one and the same piece of metal, whereby it is rendered much more irm and strong, and less liable to break, than when the pinion is riveted to its arbor7 as has heretofore been the case; also, in a novel manner of holding and securing the pinion within the body or ease ot' the chuck; and, lastly, in strengthening the body ot' the chuck by shrinking a band or bands ot' wrought-iron around and about its periphery or edge.
In accompanying plate of drawings my improvements in lathe-chucks are illustrated.
Figure lis a central vertical section through a chuck made according thereto 5 Fig. 2, a section taken in the plane ot the line x x, Fig. l, and Fig. 3 al detail view ol the pinion and its arbor.
Similar letters of reference indicate like parts.
A in the drawings represents the chuck, which is of that class commonly known as scroll-chucks,77 and in construction is similar thereto, except so far as the present invention extends, as before stated, and therefore needs no particular description herein; B B B, the jaws, moving in guides C ot' the face of the chuck, and drawn in or out by turning the disk or plate D, with the scrolls E of which the said jaws are interlocked; F, the pinionwheel engaging with the teeth of the scrolldisk D, and H its arbor or shaft, the two being formed of one and the same piece of meta-l,
and thereby, as is obvious, imparting great strength and firmness to it, obviating all liability of its becoming broken or slipping upon its arbor, as is often the case with the ordinary manner of riveting the pinion to its arbor.
For the insertion of the pinion-wheel F in its proper place within the chuck, a circular opening, I, is made in and through its side of suitable size to allow the pinion to be passed through it, placing one end of its arbor in the socket K, made in the central portion of the chuck, the other end of the arbor turning in a bearing of the hollow screw-nut M, which is screwed into the opening I so as to be flush, or nearly so, with the side of the chuck, forming by its inner end a shoulder, N, between which and the central portion of the chuck the pinion is held, as plainly shown in the drawings, the pinion being turned by means oi' a wrench or other suitable implement applied to its outer and square-headed end, O.
By securing the pinion in the body ot' the chuck through a hollow screw-nut, as described, it is plain to be seen that it can be easily removed, and without disturbing any other portion or portions of the chuckan advantage ot' much importance and convenience in its use.
To strengthen the body of the chuck I shrink in any proper manner around the same a ring, I?, of wrought-iron, whereby the weight of metal necessary to be used for the body of the chuck is greatly reduced in amount, while a strong, secure, and durable chuck is produced.
That l claim as new, and desire to secure by Letters Patent, is-- The chuck consist-ing` of the jaws B, scrolldisk D, pinion F, and hollow shouldered nut M, combined and operating substantially as described, for the purpose specified.
D. E. VHITON.
