HAMMER.

Specification of Letters Patent.

Patented Nov. 28, 1916.

Application filed June 22, 1915. Serial No. 35,644.

To oZZ whom it may concern:

Be it known that I, JOHN H. MOORE, a

citizen of the United States, residin at Marsden, in the county of Love and tate of Oklahoma, have invented a new and useful Hammer, of which the following is a specification.

This invention has reference to improvements in hammers, and its object is to provide a hammer head with means whereby a wooden handle becomes so firmly seated in the eye of the hammer that the head of the hammer cannot fly off from the handle under conditions of use.

Vihile the invention is particularly adaptable to hammers it is of use in connection with like tools where the head or body of the tool is made fast to a wooden handle, and hence the invention is not confined strictly to hammers, but for convenience of description the terms hammer and hammer head will be used with the understanding that the invention is not thereby limited to such particular implement.

In accordance with the present invention the hammer head has the eye portion constructed in general after the usual practice. There is provided by the present invention a wedge member having at one end a laterally projecting plate-like cap of sutficient size to cover the outer end of the eye of the hammer and overlap thebody of the hammer in the immediate neighborhood of the eye passage. In completing the hammer this plate-like end of the wedge is welded to the body of the hammer about the eye, so that the whole structure becomes in elfect a one-piece structure with the wedge permanently united to the hammer head. Then the handle is driven into the eye of the hammer from the end remote from that closed by the wedge cap or plate-like end,

tailed description, taken in connection with the accompanying drawings forming part of this specification, withthe further understanding that while the drawings show a practical form of the invention, the latter is not confined to any strict conformity with the showing of the drawings, but may be changed and modified so long as such changes and modifications come within the scope of the appended claim.

In the drawings :Figure 1 is an elevation with some parts in section showing a hammer head with the wedge member ready for application to the hammer head to be welded thereto. Fig. 2 is a longitudinal sec tion of a portion of the hammer head on a larger scale than Fig. 1 and showing the wedge member in welded union with the hammer head. Fig. 3 is a central section at right angles to Fig. 2. Fig. 4 is a perspective view of the wedge member before being welded to the hammer head.

Referring to the drawings there is shown a hammer head 1 having the usual shank 2 through which an eye 3 is formed, such eye being usually of customary shape flaring somewhat toward the outer end where the side walls have a still greater flare, indicated at 4.

There is also provided a wedge 5 elongated in the direction of the length of the hammer head and somewhat shorter than the length of the eye 3 in a corresponding direction; that is, lengthwise of the hammer head. The wedge is of a length from the base portion to the point somewhat greater than the distance of the junction of the flares 4: with the remainder of the eye 3, such junction point being indicated at 6. The narrow or edge portion of the wedge indicated at 7 may be relatively sharp, while the ends of the wedge approach such edge portion 7, the latter being presentedtoward the entering end of the eye 3 when the wedge is in operative position.

The butt end of the wedge is in the form of a laterally expanded cap or plate-like portion 8 of a size both laterally and longitudinally somewhat greater than the outer end of the eye 3, so as to overlap the corresponding portions of the hammer head.

In the course of manufacture the hammer head 1 is made in the usual manner, and may be a structure such as is obtainable upon the market. i

The wedge 5 with its cap portion 8 is manufactured separately from the hammer head 1 and is made of a suitable metal such as steel. lVhere the cap portion 8 overlaps the outer end of the eye 3, which overlapping is entirely about said open end of the eye, the cap 8 is welded to the body of the hammer head, such welded union being diagrammatically represented at 9.

The side walls of the wedge 5, which appropriately taper, are suitably spaced from the corresponding side walls of the eye 3 and include that portion of the eye occupied by the diverse walls f. The wedge is longer than the walls l and hence enters for a distance into the main portion of the eye 3 toward the inner end of said eye into which end, shown at 10, the handle is introduced, such handle, however, not being shown in the drawings, since it may be an ordinary wooden hammer handle. Since the side portions of the wedge 5 usually do not reach the corresponding walls of the eye 3, spaces 11 remain between the end walls of the wedge and the corresponding walls of the eye'3. Also wedge-shaped spaces 12 are formed between the side faces of the wedge 5 and the divergent walls at.

Vith a hammer equipped with a wedge 5 having a cap 8 welded to the head of the hammer, and so closing the outer end of the eye, a wooden handle forced into the eye 8 through the end 10 thereof ultimately e11- gages the wedge 7 and is split and spread thereby, being forced on opposite sides of the wedge through the contracted space between the angle junctions 6 of the walls 4 and the main portion of the eye 8, and these split portions are then forced into the spaces 12 into which they swell and constitute effective locking means preventing the accidental withdrawal of the hammer handle from the head or the removal of the head from the handle. In fact, when the head and handle are once united it is practically impossible to remove the hammer handle short of the application of destructive forces.

The cap 8 forms a complete closure for the outer end of the eye, and a means for the integral union of the wedge with the hammer head, so that the wedge cannot become loosened and the handle when once inserted cannot be removed.

The cap 8 projects beyond that face of the hammer head remote from the handle entering end of the eye 3, so that in the act of withdrawing a nail or the like from a surface the cap 8 constitutes a laterally extended boss or projection correspondingly holding the hammer head away from the surface against. which it engages, wherefore a nail may be withdrawn from the surface with greater facility than in the ordinary construction of hammer. In the case of other tools the cap 8 provides a projecting bearing surface not only completely protecting the handle at the corresponding end of the eye, but providing a prying fulcrum upon which the tool may rock to a greater extent than is the case with hammers and the like as ordinarily constructed.

hat is claimed is The method of providing hammer or other tool heads with handle holding Wedges integrally united thereto and located in the handle receiving eyes of said heads, which consists in providing a cap plate of greater area or spread than the area of the outer end of the eye and having a wedge fast thereto and adapted to enter the eye of the hammer head, and then welding the edge portion of the cap plate to the exterior face of the hammer head about the eye with said cap plate exterior to the hammer head and projecting from the face of the head to which it is welded.

In testimony, that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.

JOHN H. MOORE.
