WASHER FOR LATH ES.
Specification of Letters Patent.
Patented March 12, 1907.
Application filed May 29,1906. Serial No. 319.303-
To all whom it may concern.-
Be it known that I, EARL C. ADAMS, a citizen of the United States of America, residing at Belle Vernon, in the county of Fayette and State of Pennsylvania, have invented certain new and useful Improvements in Washers for Lathes, of which the following is a speci- "vide simple and effective means for loosemng the connection between the chuck and faceplate of a lathe, so that the chuck may be easily unscrewed from the spindle.
The construction of my improvement will be fully described hereinafter in connection with the accompanying drawings, which form a part of this specification, and its novel features will be defined in the appended claim.
In the drawings, Figure 1 is a side elevation of a ortion of a lathe-spindle having a chuck an my improved adjusting device applied thereto. Fig. 2 is a front elevation of the adjusting device, on a larger scale, removed from the spindle. Fig. 3 is a horizontal section on the line 3 3 of Fig. 2, and Fig. 4 is a vertical section taken on the line 4 4 of Fig. 2.
The reference-numeral 1 designates a lathespindle having its outer portion 2 screwthreaded and formed with the usual conical projection 3. An annular flange or collar 4 is formed on the spindle, and against this collar my improved device is applied.
The reference-numeral 5 designates a faceplate upon which is secured the chuck 6.
The adjusting device comprises two concentric rings 7 and 8, loosely secured together by means of diametrically opposite screws 9, which extend into threaded openings 10 in the ring 8 and through unthreaded openings 11 in the ring 7, the latter being countersunk to accommodate the heads of the screws 9. The inner faces of the rings 7 and 8 are recessed to form tapering seats 12 for wedgeshaped keys 13. These keys when driven down to frictionally engage the upper portions of the walls of the recesses in the rings force the rings apart and firmly clamp them between the collar 4 and the face-plate 5 upon the spindle, as illustrated in Fig. 2.
The utility and o eration of the device as thus constructed Wlll be readily understood. As long as the wedge-keys are in the downward position illustrated in Fig. 4 the two rings 8 and 7 are forced apart to firmly clamp them between the collar 4 and face-plate 5; but when it is desired to remove the chuck 6 the keys are loosened by tapping them on their lower ends with a suitable implement, and thus the outer ring 7 is permitted to recede toward the ring 8, after which the chuck and face-plate 5 may be readily unscrewed from the spindle.
While I have shown the larger ends of the wedge-keys up ermost in the drawings, it is obvious that t e osition of these keys may be reversed, in w 'ch event they would be driven upward to wedge them between the Tings 7 and S and downward to release the icy.
I would have it understood that the invention includes all such modifications and variations in the minor details of construction as may be resorted to without departing from the scope of the claim.
Havmg fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
The combinationiwith a lathe-spindle havin a fixed collar, a d a chuck received on the spindle and havirg a face-plate, of two eoncentric rings loosely mounted on the spindle between the collar thereof and the face-plate of the chuck, and one of which rings is loosely connected to the other ring, the rings having registering parallel grooves in the adjacent faces, and wedge-keys in the grooves, one at each side of the s indle for spreading the rings and forcing t e same into engagement with the collar and face-plate respectively.
In testimony whereof I affiX my signature in the presence of two witnesses.
EARL O. ADAMS.
