UNITED ASTATES PATENT OFFICE.
WILLIAM WAKELEY, OF HOMEI-, NEW YORK.
SELF-FEEDING DRILL.
Specification of Letters Patent No. 18,652, dated November 17, 1857.
To all whom fit may concern:
Be it known that I, VILLIAM VAKELEY, of Homer, in the county of Cortland and State of New York, have invented a new and useful Improvement in Machines for Drilling Metal; and I do hereby declare that the following is a full, clear, and eXac-t description of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l, is a side view of my improvement. Fig. 2, is a horizontal section of the same, taken in the line (w) (ai) in Fig. l. Fig. 3 is a transverse section of the handle and lever, taken in the line (y) (y) in Fig. 2.
Similar let-ters of reference indicate like parts in the several figures.
This invention consists in connecting the feed movement with the driving movement of the drill in such a way that both may be operated simultaneously, when desired, by the turning of a single crank, and the feed also operated singly or alone when necessary; so that the drill or arbor may be moved forward or backward with increased speed to any desired point or position.
To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.
A, represents a bar, having two projections or head stocks B, C, attached, in which an arbor D is fitted. This arbor has a drill E fitted in its front end; and a screw thread is formed on the back part of the arbor.
On thearbor D, a bevel pinion El is placed. This pinion is not rigidly attached to the arbor, but is connected with it by a feather and groove; so that the arbor will be rotated with said pinion, butstill allowed to slide longitudinally through it. Also on the arbor D, and directly back of the pinion E, a pinion F, is'placed. This pinion has an internal screw thread which fits on the screw portion of the arbor, and serves the office of a nut.
G is a bearing attached to or connected in any proper way with the bar A. Within this bearing a. hollow shaft H, is placed. This shaft has an arm I, attached to its outer end, and a bevel wheel K, is attached to its inner end; the said wheel K gearing into A wheel J, is also placed loosely on the shaft I-I. This wheel J, is connected with the wheel K, when desired,
so that the wheel J, will be rotated with the wheel K, `by means of a clutch formed of two pins (b) (b), which are attached to a cross-head (c) at the inner end of a shaft L, which passes through the center of the hollow shaft H; the pins (b) (b) passing through the wheel J, and causing `the wheel J, to rotate in consequence of acting against pins (d) (d) attached to the face of the wheel K, as shown clearly `in Fig. 2.
To the outer end of the shaft L, one end of a lever M is connected; the said shaft L having two buttons (e) (e) upon it, between which buttons the end of the lever is fitted loosely o n the shaft. The said lever M is pivoted to the arm I, as shown at (f), and forms a crank, a handle N being attached to its outer end.
On the lever M, a short rock-shaft (g) is placed; said shaft having an arm (l1.) attached, which arm bears upon a spiral spring (i) attached to the lever M. A rod (j) is attached to the opposite side of the shaft (g), said rod having ahead or lip formed on it; and spring having a tendency to keep the head or lip (k) depressed or pressed downward.
O, represents the head-rest, which is fitted on the bar A, so that it may slide thereon; a rack P being formed on the upper surface of the bar by which the head may be retained at any desired point; the teeth serving as stops.
From the above description of parts, it will be seen that by turning the lever or crank M, the two wheels J, K, will, when connected by the pins (b) (b), (d) (d), be turned simultaneously, and said wheels J, K, will rotate the pinions F, El, the'pinion El rotating the arbor D, and drill E, and the pinion F feeding the drill to its work, which is placed against the head rest O. When, howeverthe drill is to be run or moved back, the shaft L is shoved inward by moving the lever M, and the pins (b) (E), are thereby shoved inward free from the pins (d) (d), and the wheel K moves or is rotated alone; and as the pinion F, is consequently not rotated, the arbor will be moved longitudinally by the pinion F, with an increased speed and in either direction according to that in which the shaft H is turned, the pinion F, forming in the latter case a stationary nut. Thus it will be seen that by a very simple means an automatic sired.
When the wheel K is connected with the wheel J, the pins (b) (b) are retained or held inward by the lip or head-(7c) which catches over the edge of the arm I. In order to disengage wheel J from wheel K, the head or lip (7c) is thrown up free yfrom the side of the arm I; no catch or fastening being required to keep the pins (b) (b) outward from the pins (d) (al), as the feed movement alone works with but little friction, and the pins (b) (b) are not liable to move casually.
I would remark that the bar A may be placed in either a horizontal or vertical position, as the drill will work equally well in either position.
Having thus described my invention, what I claim as new and desire to secure by Letters-Patent, is:
1. The arrangement of the gearing J K, F, El, as shown, whereby both pinions E1, F, may be operated at the same time, so that the drill E may be rotated and fed to its work by the rotation of a single shaft or crank.
2. I also claim the arrangement of the lever M, with the shaft (g), and catch (la), as shown, in connection with the rod L, and cross-head (c) with the pins (b)4 (b), attached for the purpose of connecting the wheel K, with the wheel J, and disconnecting it therefrom, as described.
