DAVID E. WHITON, OF WEST STAFFORD, CONNECTICUT.
" SCROLL-CHUG K.
SPECIFICATION forming part of Letters Patent No. 224,119, dated February 3, 1880.
Application filed February 28, 1879.
To all whom it may concern Be it known that I, DAVID'E. WHITON, of West Stafford, in the county of Toliand and State of Connecticut, have invented certain new and useful Improvements in Scroll- Chucks; and I do hereby declare that the following is a full, clear, and exact description thereof, whereby a person skilled in the art can make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.
Like letters in the figures indicate the same parts. i I
My improvement relates to that class of lathe-chucksin which thejaws which gripe the object held are moved out and in by the rotation of a scroll which enters into teeth in the back of the jaws. It has for its objecta simple method of rapidly moving the jaws out or in, to place them for holding any object de sired, while at the same time it is provided with means for firmly and powerfully griping the object held when the jaws are nearly in their proper position.
My invention consists in the mechanism which will be hereinafter described.
In the accompanying drawings, on two sheets, Figure 1 shows a side view of my improved chuck. Fig.2 shows a face view of the same with the handle for operating it removed. Fig. 3 shows a vertical longitudinal section through the middle of the chuck. Fig.4 shows the face of the scroll-plate, with the holes for the key shown in dotted lines. Fig. 5 shows the key detached from the chuck in a position at right angles to that shown in Fig. 1.
A is the part forming the bodyot the chuck. It is channeled out. on its face for the reception of the jaws, and upon the rear is furnished with a circular groove for the reception of the scroll-plate. B a collet screwed upon the reduced rear portion of the part A, and retains the scroll-plate in its place. i The part B is provided with screw-holes or other devices for attaching to the.face-plate of a lathe, or a screw-thread may be cut in the central opening of the part A, for a similar purpose, in any usual manner. 7
C is the scroll-plate, turnin g within and upon the body A, and having upon its face a scroll, as shown in Fig. 4. D D D. are the jaws, They slide in or out upon grooves or hearings in the body A in the usual manner, and are furnishedwith teeth upon the rear side, which enter into the spiral scroll on the key is placed in the socket.
scroll-plate, so that the rotation of this plate moves the jaws radially in or out relatively to the axis of the chuck.
E is a circular rack or crown wheel upon the outer 'rim of the body A, which extends beyond the circumference of the scroll-plate. G G G are holes arranged radially in the scroll-plate for the insertion'of the key to turn it; There may be three, four, or any desired number of these holes.
The chuck isoperated by means of the key shown in Fig. 5. It is furnished with an end bearing, J, which fits into the sockets G and turns in them, and also with a sectional pinion, K, which engages in the teeth E when the The pinion K is not complete, but has several teeth cut away, so that when this part is turned so as to come opposite the teeth E they donot engage with the pinion, but pass freely.
H is across-handle to the key, which serves to turn the pinion, and at the same time, by its direction, shows the position of the open part, so that it can be readily placed opposite the gearing on the body A.
The operation of my invention is as follows: When it is desired'to hold any article in the chuck, the key is inserted in one of the sockets G, or in each of them successively, with the open part of .the pinion against the gearing on A, and by it the scroll-plate is rapidly turned to'bring the jaws against the object to be held. As soon as they touch the key is turned by means of its handle, and the teeth of the pinion enter into the teeth E, giving the scroll a slow and powerful motion to firmly gripe and hold the object within the jaws.
What I claim as my invention is 1. The herein described key, having a straight stem and a sectional pinion, said stem operating as a lever to turn the scroll plate, and also as a journal for the sectional pinion which engages with a circular rack on the body of the chuck when the-key is rotated on its axis, substantially as set forth.
2. In a scroll-chuck, the combination of the body A, provided with the circular rack E, the scroll-plate C, and a key operating as a lever to turn the scrollplate independently, and also furnished with teeth to act upon the circular rack, substantially as described.
DAVID E. WHITON.
