Description

'UNITED sTATEs PATENT oEEIoE.

F. MGNAIR, OF FULTONHAM, OHIO.

HAND-DRILL.

'\ Specification of Letters Patent No.

To all 'LU/wm t may concern:

Be it known that I, F. MCNAIR, of Fultonham, in the county of Muskingum and State of Ohio, have invented a new and Improved Hand-Drill for Drilling in Metal; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l, is a front elevation of my invention. Fig. 2, is a side elevation of ditto.

bimilar letters of reference indicate corresponding parts in the two figures.

The object of this invention is to obtain a portable hand drill, one that may be readily manipulated and capable of being more generally adapted to various kinds of work than those previously used.

lThe invention consists in attaching the frame of the drill, on or in which frame the sliding gate works, to a movable or adjustable bed, which is hinged or jointed to a permanent or stationary bed so that the drill may be used either in a vertical or horizontal position as the nature of the work may require. y

To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.

A, represents a horizontal bed plate supported at a suitable height by any proper framing and having a bed B, attached at one end by a joint or hinges a, so that the bed B, may be raised in a vertical position perpendicular to the bed A, or be adjusted horizontally in the same plane with it. The adjustable bed B, has a leg b, attached to it, to support its outer end when in a horizontal position, as shown in red, Fig. 2, and the bed is retained in a vertical position by hooks c, c, which are attached to the bed A, and lit over pins d, attached to the sides of the bed B.

To the adjustable or movable bed B, a metal frame C, is attached,said frame being formed of two end pieces e, e, connected by guide bars 7", f, one at each side. On the guide bars f, f, a meta-l gate D, is placed, said gate having an arbor E, tted in it. In the lower end of arbor E, a drill g, is placed. To t-he upper end of the gate D, a screw F,

is attached, said screw passing through the outer or upper end piece c, of the frame C, and having a hand wheel G, on its outer end. On the arbor E, a bevel pinion I-I, is placed and a bevel wheel I, gears into the pinion H, said wheel I, being on a shaft J, which has its bearing in the gate D. To the outer end of the shaft J, a crank K, is attached.

Vhen the bed B, is elevated at right angles with the bed A, a vertical drill is obtained, the drill arbor E, being rotated by turning the crank K, and the drill is fed to its work by turning the screw F, the article to be drilled being placed on the bed A. IV hen the bed B, is in a horizontal position a horizontal drill is obtained, as shown in red, Fig. 2.

The vertical drill is preferable for drilling plates, bars, and in fact all work which may be laid on the bed A, flatwise, but there are certain kinds of work that cannot be drilled with the drill in a. vertical position without giving the gate D, a great length of movement to allow space to receive the work or article, as for instance, wheel tires and various other articles, and the wheels if placed horizontally on the bed A, require the drill to be adjusted in a horizontal position.

The device therefore herein described may be made quite portable as the gate D, does not require an extended movement in order that various kinds of work or articles may be drilled by it, and by adjusting the bed B, as shown the implement may be adapted with facility to various kinds of work.

I am aware that drills have been constructed or formed of a sliding gate containing the drill arbor and having a feeding screw attached, and I therefore do not claim broadly and separately such parts, but,

Having thus described my invention, what I do claim as new and desire to secure by Letters Patent, is,

The arrangement of the feed screw F, and sliding gate D, and frame C, in combination with the adjustable bed B, as and for the purposes herein shown and described.

F. MCNAIR.
