SPECIFICATION forming part of Letters Patent No. 655,324, dated August '7, leoo.

Application led January 27, 1899. Serial No.7031606. (No model) To all wtont it nung concern:

13e it known that I, GEORGE J. CAPEWELL, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Combination-Tools, of which the following is a specification.

This invention relates to a tool which can be conveniently used for driving nails into boxes or barrels for securing their covers or heads or for extracting nails from boxes or barrels, so that they may be opened.

The object of the invention is the production of a simple tool which is convenient for household, oflice, or store purposes where the requirements are light and the use is limited and which is so designed that it can be manufactured very cheaply and will be very stron g and ethcient in use.

The embodiment of the invention illustrated by the accompanying drawings has a thin case formed of a single piece of metal, with an integral driving-head projecting from one edge and an integral tang projecting from another edge, with a handle iiXed to the tang. A pair of jaws, one of which is liXed and the other is pivotally held, with a leafspring normally thrusting the movable from the fixed jaw, is located in a mortise in the case, so that the beak ends of the jaws project from the edge opposite the handle, and a lever is pivotally held in the mortise in the case, so that one end bears against the back edge of the movable jaw and the other end projects outwardly from the case opposite the drivin g-head and forms the fulcrum ofthe tool when it is being employed for extracting a nail.

Of the drawings, Figure l shows a side View of the tool. Fig. 2 is a view with the case cut in section, so as to show the jaws, the springs, and the lever in side elevation; and Fig. 3 is a view looking at the back edge of the tool.

The case l is preferably formed of caststeel or a similar tough metal. One edge of the case is extended and enlarged, so as to form a cylindrical head 2, which may be employed Yfor driving nails, brads, tacks, and the like fastenings, and another edge is extended at right angles to the driving-head to form an integral tang 3, by means of which the handle-bar 4 may be firmly fastened to the case. The handle is usually made of Wood, and a ferrule 5 is preferably driven on the end to prevent the wood from cracking or splitting.

The case, which in this form of tool is not much more than a thin plate, has a longitudinal mortise, which nearly divides it into two plates. A jaw 6 is fixedly held in this mortise near one side by a pair of pins 7. This jaw has a curved point or beak-shaped end 8, which projects beyond the edge of the case. Loosely held in the mortise by a single pin 9, opposite the jaw 6, is a complementary jaw lO, which has a similarly-pointed or beak-shaped end ll, that projects beyond the edge of the case. A leaf-spring 12 is placed between the jaws, and one end of this spring presses against the edge of the fixed jaw, while the other end presses against the edge of the movable jaw, so as to hold the beak of the latter jaw away from the beak of theiformer jaw with a yielding force. A lever 13 is held by a pivot let between the parts of the case, with its short arm bearing against the edge of the movable jaw and its long arm projecting outwardly almost in line with the driving-head. On the long arm of the lever a shoe 15 with a wide bearing-face is fastened, and this shoe forms the fulcrum upon which the tool is rocked when the jaws are being closed upon a nail and the nail is being drawn.

For driving nails, tacks, brads, or the like fastenings the toolis employed as an ordinary hammer, the parts being so arranged that the full efect of the momentum is obtained when a blow is struck, and the parts are so located that a fastening may be driven close up to a wall extending at right angles with the surface into which the fastening is being driven. The parts are very simple to form, are exceedingly strong, and there are no loose parts to shake and become battered when a blow is struck for driving a fastening.

When a nail or other fastening is to be eX- tracted, the fixed beak is crowded into the material surrounding the head of the fastening, and then the tool is rocked on the shoe. This causes the end of the short arm of the lever to force the movable beak toward the ICO other beak with great pdwer and to grasp the head of the fasteningbetween the beaks with.

be cut into or marred. The shoe is so located that the length of the fulorum increases as a nail is being drawn, and it projects out of the wood and requires less force.

I claim as my invention-W A tool consisting of the combination of a thin case with an integral neck having a driving-head projecting from one edge and an integral tang projecting from another edge with a handle fixed to the tang, a jaw formed of a dierent metal from the case and held in a mortise in the oase with its beak projecting substantially opposite to the handle, a pair of pins extending through the side of the case and the jaw and holding the jaw fixed with its edge against the back of the neck, a jaw formed of a different metalfroni the case and held in the mortise with its beak projecting substantially opposite to the handle, a pin extending through the side of the case and this latter jaw and pivotally retaining the jaw in place, a spring located between the jaws with its ends normally thrusting the beak of the pivoted jaw from the beak of the xed jaw, a lever held in the mortise on one side of the jaws with the edge of a short arm bearing against the edge of the pivoted jaw and a long arm projecting outwardly from the case substantially in line with the drivingneck, and a pin extending through the side of the case and the lever pivotally retainingthe lever in place, substantially as specified.

GEORGE J. CAPEWELL.
