RATGHET DRILL.
No. 368,162. Patented Au 9, 1887.
W y w/fiw UNITED STATES PATENT OFFICE.
JAY NOBLE, OF ST. LOUIS, MISSOURI, ASSIGNOR OF ONE-HALF TO JAMES A. GUMERSELL, OF SAME PLACE.
RATCHET-DRILL.
SPECIFICATION forming part of Letters Patent No. 368,162, dated Au ust 9,1887.
Application filed March 26, 1887. Serial No. 232,530,
To all whom, it may concern:
Be it known that I, JAY NOBLE, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement 5 in Ratchet-Drills, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings,forming part of this specification, and in which- Figure I is a perspective view of my improved drill, showing, also, part of a railwayrail and the frame in which the drill is held.
Fig. II is an end view of the friction device.
Fig. III is a section taken on line III III, Fig.
IV. Fig. IV is a section taken on line IV IV, 1 Fig. III; and Fig. V is a section taken on line V V, Fig. III.
My invention relates to an automatic feed for ratchet-drills; and I have shown it in corn nection with a railway-rail and a suitable frame for holding the drill up to the rail; but it may be used for other and various purposes.
My invention consists in features of novelty hereinafter fully described, and pointed out in the claims.
Referring to the drawings, 1 represents a railway-rail; 2, a frame engaging with the rail and provided with a rear support, 3, by which it is held up off the ties; 4, the drill; 5, the ratchet; G, the handle of the ratchet, and 7 the feedscrew that centers against the back of the frame 2, as shown in Figs. III and V, and which enters the spindle or sleeve 8 of the drill, all of which parts are ordinary, and in them per 80 I claim no invention, my invention relating entirely to the attachment whereby the drill is fed automatically, and which consists in securing a friction-wheel, 9, to the feed-screw 7, which turns with the screw. Loosely fitting on the feed-screw, preferably 0 outside of the friction-wheel 9, is a block or plate, 10, which may be held from end movement on the screw by means of a collar, 1], or it may be held by other suitable means which will allow the screw to turn independently of This block 10 has an arm, 12, to which is secured on the under side aspring, 13, to bear against the periphery of the friction-wheel 9, and which may be adjusted to increase or di- (No modcLl minish its pressure upon the roller by means of asetscrew,1.4,passing through thearm 12. The 0 plate or block 10 has preferably also a pro jection, 16, which bears against the frame 2 to prevent the block or plate from being turned by the friction wheel upon the spring 13. Other means could be provided to keep the block from turning.
The operation is as follows: \Vhile the drill is cutting, the friction-wheel 9 and screw 7 turn with the drill, the friction between the wheel and the spring 13 not being sufficient to keep the wheel from turning while sufficient pressure is on the drill to cause it to out. As soon as the drill has cut for a short time, the backward end pressure of course decreases, and there not being sufficient friction between the outer end of the screw 7 and the frame 2 to cause the wheel 9 to turn, under the pressure of the spring 13 the wheel stops, together with the fcedscrew, and the spindle or sleeve 8 turns upon the feed-screw, advancing the drill auton'iatically. Then, as soon as the drill has been advanced a short distance, the friction of the spring 13 upon the wheel 9 is overcome and the screw 7 starts to turn with the sleeve or spindle 8 and the drill, and the feed is thus automatically stopped, and thus the operation goes on, the drill being automatt cally fed, as necessary.
I claim as my invcntion-- 1. In a ratchet-drill, the combination of the feed-screw, frictioirwheel on the screw, sta tionary plate, and a spring on said plate ongaging the frictioirwheel, substantially as and for the purpose set forth.
2. In a ratchet-drill, the combination of the feed-screw, frictionwheel secured to the screw, stationary plate, and an adjustable spring on the plate bearing against the wheel, substantially as and for the purpose set forth.
In a ratchetdrill, in combination with the feed-screw, a friction-wheel secured to the screw, a plate loosely mounted on the screw, a spring secured to the plate, a set-screw for adjusting the pressure ofthe spring, and means for keeping the plate from turning, SllbStiLlP tially as set forth.
4:. In a ratehetdrill, in combination with which the drill is supported and upon which the set-screw, a friction-wheel secured to the the projection 16 bears, substantially as and screw, a plate, 10, loosely held on the screw, for the purpose set forth.
an arm, 12, on the plate, a spring, 13, secured JAY NOBLE. 5 to the arm, a set-screw, 14:, passing through In presence ofthe arm and bearing against the spring, a pro- GEO. H. KNIGHT,
jection, 16, on the plate, and a frame, 2, by EDW. S. KNIGHT.
