COMBINATION-TOOL.

SPECIFICATION forming part of Letters Patent No. 322,914, dated J'uly 28, 1885.

Application filed June 6, 1885. (No model.)

To all whom it may concern:

Be it known that I, GEORGE CUTTER, of Boston, (Somerville,) in the county of Middlesex, State of Massachusetts, have invented a certain new and useful Improvement in Combination- Tools, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- 7 Figure 1 is a side elevation of my improved combination-tool represented as closed; Fig. 2, a vertical longitudinal section of the same, and Fig. 3 a side elevation showing it arranged as a pair of dividers or compasses.

My invention relates to that class of combination-tools which are designed,principally, for domestic use; and it consists in a novel construction and arrangement of the parts, as hereinafter more fully set forth and claimed, the object being to produce a simple, durable, and effective implement, which embodies in compact form all of the desirable features and characteristics of the various tools which enter into the combination.

The nature and operation of the improvement will be readily understood by all conversant with such matters from the following explanation, its extreme simplicity rendering an elaborate description unnecessary.

In the drawings, A represents the handle; B, the brad-awl, and G the screw-driver. The body of the brad-awl is flat, and provided with an elongated slot, D, and point E. The body of the screw-driver is flat and provided with a wide point, m, and narrow point x, to adapt it to fit screws of different sizes, the narrow point being slightly thinner than the wide point.

A set-screw, H, provided with a washer, 7), passes through the slot D, and is fitted to work in a threaded hole in the center of the body of the screw-driver, thereby pivoting said driver and enabling it to be readily reversed or turned end for end.

A socket, t, is formed in the lower end of the handle A, said socket being adapted to receive either end of the screw-driver G. The lower end of the body of the brad-awl B is tapered, and provided with a cuttingedge, f, at either side to form the countersink z. The brad-awl is also provided with angular or cutting edges, being square in cross-section where,it joins the countersink, and tapered to its point. It may, however, be made round, if preferred. The shank k of the brad-awl, where it enters the handle A, stands at one side of the longitudinal axial line of said handle, said line, when-projected, passing between the brad-awl and screwdriver.

To prepare the tool for use either as a bradawl or countersink, the screw H is loosened and the screw-driver G withdrawn from the socket t and secured in a horizontal position by said screw.

When the tool is used as ascrew-driver, the wide point it or narrow point :10, as the case may be, is inserted in the socket t, and the driver firmly secured to the body of the bradawl by the screw H.

The object in setting the brad-awl at one side of the axial line of the handle is to equalize the eccentricity of the a-wl and screwdriver. I do not, however, confine myself to this arrangement, as either the screw-driver or brad-awl may be set on the axial line of the handle, if preferred.

The brad-awl may be made round or of any other suitable form desired.

It will be obvious that when the brad-awl is used to make a screw-hole, the hole may be readily countersunk to receive the head of the screw at the same time.

Having thus explained my invention, what I claim is- 1. In a tool,substantially such as described, the combination of the following instrumentalities, to wit: a handle, a brad-aw], a countersink, and a screw-driver, the countersink and brad-awl being integral or formed in one piece, the screw-driver being provided with two ends adapted to engage a screw, and adjustably connected with the body of the bradawl, and the handle provided with an open socket adapted to receive either end of said driver and house the same when the driver is the slot D, countersink z, and point E, eonarranged for use. structed, combined, and arranged to operate 2. The improved combination-tool herein substantially as set forth. described, the same consisting of the handle GEORGE CUTTER. 5 A, provided with the open socket t, the screw- Witnesses:

driver 0, provided with the points an ac and G. A. SHAW,

screw H, and the brad-awl 13, provided with L. J WHITE.
