GEORGE H. PIERCE, OF SAN FRANCISCO, CALIFORNIA.

COMBlNATlON-TOOL.

SPECIFICATION forming part of Letters Patent No. 234,378, dated November 9', 1880.

Application filed August 13, 1880.

To all whom it may concern Be it known that I, GEORGE E. PIERCE, of San Francisco, California, have invented a new and useful Combination-Tool, of which the following is a specification.

My invention relates more particularly to the combination within one case or handle of a set of tools applicable for the use of sportsmen and others in taking apart and putting together guns, rifles, &c., in extracting the cartridge-shell after the explosion of the cartridge, and such other tools, Whatever'their uses may be, as may be found convenient and suitable to enter into the combination.

The invention consists in securing the tools, two or more, within a novel-shaped frame or handle in such a manner as that any tool may be opened out of the handle and applied for service while the remainder in the set are convenientlyinclosed in the handle somewhat similarly, asin the case of the blades of an ordinary pen-knife.

In the accompanying drawings, forming a part of this specification, Figure 1 represents a vertical cross-section of my device with one tool set for use. Fig.2 is a front view of same. Fig. 3 is a back view, giving shape of springcatch, hereinafter referred to.

Like letters of reference refer to like parts in all the figures of the drawings.

A is the case or handle, a harp-shaped piece of metal similar to those found in the ordinary pocket corkscrew, excepting that the metal is made flat instead of round, and the ends a a do not spring apart in opening out the different tools.

B is a rivet which joins the two ends a to together, andis the axle upon which each tool swings in opening out and shutting in. This rivet is slightly larger between the sides a, a, so as to form shoulders to prevent the ends being sprung together when riveting up.

C is a spring-catch which looks the tools open or shut by inserting itshooked end 0 into the notches b I) cut in the hubs e of every tool.

1 2 3 4. 5 are the different tools, combined in the present case as follows: 1 may be a screwdriver for small-headed screws. Screw-heads being generally countersunk in f re-arms, different sized screw-drivers are needed for each sized screw. 2, a forked wrench for unscrew- (No model.)

ing the plunger-nut of a gun; 3, a cartridgeshell extractor; 4, a screw-driver for large screws 5, asocket-wrench. All the tools will be exactly alike as to the form of the hub c and the position of the notches b b, which notches are so placed as to admit the hooked end 0 of the spring-catch only when the tool is fully opened out, as tool 2, or fully closed, as tools 1, 3, 4, and 5. The spring catch has its fulcrum at D, a rivet passing through the sides of the handle A, as shown in Figs. 1 and 3.

E is a little spiral spring which throws out the catch by expanding between the tail of the springcatch and the little boss F, which is in any suitable way made fast to the middle of the inside of the handle where shown.

To prevent the spiral spring dropping out it should be held in place by little projecting pins, one on the tail of the spring-catch and one on the boss F.

It is manifest that the principle involved in this invention may be applied in combining other tools, as, for instance, a file, a bradawl, a reamer, and even aknife-blade may be used.

In operating this device the thumb is pressed down on the tail of the spring-catch, which lifts the hooked end out of the notches in the hubs of the tools, leaving them free to be swung out to open. When the tool selected is swung partly out the pressure maybe released and the tool swung around until the notch in its hub reaches the point opposite the hooked end of the catch, when the hook will spring into the notch and lock the tool firmly in position. In closing the tools the operation is the same.

WVhat I claim as my invention, and desire to secure by Letters Patent, is as follows:

The combination of the solid harp-shaped handle A, having the axle B, supported in hearings in the ends a a thereof, with the notched hubs e of any suitable tools applied upon said axle, and the spring-catch C, having its fulcrum at D, and actuated by the spring E, substantially as and for the purposes herein described.

GEORGE H. PIERCE.
