WILLIAJNI H. IIAIGHT, F-NORTI-IFIELD, MINNESOTA.

HAMMER.

Application le'Februaryl, 1912.

To all 'whom t may concern:

Be it known that I, WILLIAM H. I-IAIGHT, of Northfield, Rice county, Minnesota, have invented certain new and useful Improvements in Hammers, of which the following is a specification.

rIhe Object of my invention is to provide a well balanced hammer and one that will pull a nail completely instead of partially.

Other objects of the invention will appear from the following detailed description.

The invention consists generally in a hammer having a claw portion provided with an elongated slot having its end walls reversely beveled.

Further the invention consists in providing the shank of the hammer with a seat or face to receive the head of the nail for sticking it preparatory to driving.

Further the invention consists in a backwardly turned claw having a forwardly turned tip provided with a cutting edge.

In the accompanying drawings forming part of this specification, Figure l is a side elevation, partially in section, illustrating my invention. Fig. 2 is a transverse sectional view through the handle portion, Fig. 3 is a plan view.

To make what is termed a well-balanced Y hammer, the upper and lower portions must be so formed and balanced with respect to one another that the full weight of the metal in the action of the blow will fall as nearly as possible in the center of the face. That is, if the upper or claw end of the hammer is not properly curved there will be an overhang and the head will be out of balance. Should the claw be turned down too far, much of the force of the blow is lost, as additional weight is carried by the handle, thereby requiring eXtra and undue force in making the blow. Itis desirable, therefore, that the arc described by the curved claw end should coincide substantially with the arc described by the hammer head in making the blow.

In the drawing, 2 represents the handle, 3 the head, i the shank to receive the handle, and 5 a driving face, alll of ordinary construction.

6 is the claw end of the hammer, bent backwardly over the handle and provided with an upwardly turned end 7 terminating in a chisel-edge 8, the bevel of which is on the upper side, as shown in Fig. 1. When Specification of Letters Patent.

used for hewing, the action will be somewhat similar to that of a reversed adz. If desired, this upward bend may be omitted, in which case the chisel bevel will be preferably on the opposite side of the end from where it is shown in the drawing. I prefer also to round the corners of this cutting edge, as indicated in Fig. 2.

he claw portion is provided with a longitudinal slot 9, forming a double claw for nail drawing, the walls of the slot at the end being oppositely beveled, the inner end forming a primary claw and operating much the same as in an ordinary hammer, the outer face of the hammer head forming the fulcrum, in the usual way. This inner claw is suiiicient for drawing nails below a medium size, but for longer nails the hammer is drawn backward under the head of the partially drawn nail until it engages the walls at the outer end of the slot, and the nail may then be fully extracted. It will be noted that the crowning edges of these claws overlap one another, the bevel of the outer claw being less than that of the inner claw, thereby providing more metal at the outer portion of the claw. By this construction I make it possible to engage the claws over the heads of the largest nails without undue spreading of the opening.

It will be noted in the drawing that the bevel of the claw is not required to engage the head of. the nail, but the face of the claw is used. The point of this claw is well opened, as only the largest sizes of nails are supposed to be drawn in this way and the heads are thereby allowed to enter a greater distance into the slot to engage the walls thereof.

For the purpose of sticking a nail preparatory to driving, I have provided a fiat seat 9 at the angle formed by the junction of the shank and claw of the hammer, and I also provide a recess l0 in the claw to receive the head of the nail resting on said seat. The shank of the nail is inserted through the opening in the claw and the nail will be held erect to allow the user of the hammer to stick the point of the nail into the wood at any point where the nail cannot be conveniently held in the lingers preparatory to striking it with the hammer.

I claim as my invention A hammer-head having a driving face at one end and a centrally arranged socket to receive a handle and a part projecting up- Wardly and baekvvardly over the base of said socket and provided With a longitudinal slot forming double nail-drawing claws, the Walls of said slot at the inner end thereof flaring outwardly to form a primary claw, the Walls of the slot at the outer end thereof being oppositely flared in a less degree and the slot being of less Width at the outer end than at the inner end to form a secondary claw, the crowning edges of the Walls of the slot forming the claws overlapping. one another, the primary claw performing the initial pulling operation and the Walls of the slot sliding on the shank of the nail under the head thereof until it engages With the 15 secondary claw, said secondary claw having an upwardly turned end portion forming a fiat seat for the head of the nail in the final Step of the pulling operation.

In Witness whereof, I have hereunto set 20 my hand this 13th day of February, 1912.
