HAMMER.

SPECIFICATION forming part of Letters Patent No. 619,608, d'ated February 14, 1899.

Application filed December 4, 1896. Serial No. 614,410. (No model.)

T0 all whom/ it may concern:

Be it known that I, WILLIAM H. PENNY, a citizen of the United States, residing atDanbury, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Hammers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to hammers.

The object of the invention is to provide a hammer so constructed and provided with means whereby the implement may be used for the ordinary purposes of a hammer, and whereby in Withdrawin g a nail or in similar opcrations the Wood or other substance against which the fulcrum of the hammerbears will be prevented from becoming injured.

Further, the object of the invention is to provide a hammer of such construction that in the operation of withdrawing a nail or in a similar operation slipping of the hammer will be prevented, thus avoiding scratching or other in jury to the body against which the hammer rests, and also allowing the operation to be accomplished with a single rocking movement of the hammer.

Further, the object of the invention is to provide a hammer having its bearing-surface provided with a cushion permanently attached to the hammer, the cushion being of such form as to present its greatest surface at the point where most strain is-imposed upon the hammer in withdrawing a nail or in a similar operation.

W'ith these objects in view the invention consists, essentially, in the construction substantially as hereinafter described and claimed.

The invention is illustrated in the accompanying drawings, in which- Figure 1 is a side elevationof a hammer constructed in accordance With my invention, the opening for the reception of the pad or cushion and the opening for the reception of the handle being shown by dotted lines. Fig. 2 is a perspectiveview of a hammer-head constructed in accordance with my invention, the pad or cushion being removed in order to show more clearly the construction of the hammer; and Fig. 3 is a top plan View of a hammer-head with the pad orcushion in place, showing by dotted lines the side edges of the openin g for the reception of the pad or cushion.

In the drawings, A represents a hammerhcad which is of the same general form as that ordinarily employed and is provided with the usual claws a, which are segmental, as usual. The upper ,portion of the head is provided with an indentation B, which may be of any suitable or desirable size consistent with the preservation of the strength of the hammer. The indentation is preferably so formed as to leave very thin edges b at the sides of the indentation in order that the edges may easily be covered by the pad to be described hereinafter.

Arranged in the opening B is a pad C, which may be of rubber, felt, or any other similar or suitable material which in the use of the hammer will aford a yielding surface, one which will not scratch or abrade when brought Violently into contact with a polished or other surface, and which will prevent slipping of the hammer when pressed against a surface in drawing a nail or in a similar operation. The pad is of a form and is so arranged on the hammer that that portion of it which abuts against the claws has its upper surface fiush with the upper surface of the claws, and to this end the edges of the opening receiving the pad or cushion near the claws are formed a distance below the surface corresponding to the thickness of the pad. From the point c where the pad abuts against the claws the pad gradually increases in thickness to its forward end 02. This form is desirable for the reason that in the use of the hammer in withdrawing a nail greatest strain Will naturally be imposed upon the portion 02 of the pad. From the point c2 the pad is preferably formed to extend abruptly downward over the front end of the hammer, covering the same, thus forming a covering for the entire surface of the hammer brought into contact with work in drawing a nail.

The pad or cushion may be retained in the indentation in the hammer in any suitable IOO way, as bymeans of cement or the like; but I preferably retain it in place permanently b the use of a screW 03, passed transversely through suitable openings in the head of the hammer and through the pad.

Beneath the indentation B for the reception of the pad or cushion is an opening D of the usual form for reeeiving a handle for the implement.

From the foregoing description it Will be clear that by the described construction I produce in a cheap and inexpensive manner a hammer capable of all the uses of the ordinary ham mer, with the advantage that it may be used on a highly-polished or other easily injured surface for the purpose of drawing nails or for similar'operations Without the possibility of in j ury, and that sli ppin g, which frequently occurs in withdrawing a nail, will' entirely be avoided.

Having thus descrihed my invention, What I claiin as new, and desire to secure by Letters Patent, is-

1. A hammer-head having in the upper portion thereof an opening above the opening for the handle, a pad of soft or yieldingmaterial arranged permanently in the indentation and having its upper surface fiush with and forming a continuation of the claws of the hammer, substantially as described.

2. A haminer provided with an indentation in its upper portion, a pad of soft or yielding substance arranged in the indentation, and having its upper surface arranged contiguous to the upper surface of the claws, the pad being flush With the surface of the claws at the point adjacent to the same, and grad ually increasing in thickness from I(his point, Whereby an increased thiokness of material is presented at the point where most strain is imposed in the use of the hammer, substantially as described. i

3. A hammer provided in its lower porton with an opening for the reception of a handle, and With an opening or indentation in its upper portion of greater size than that in its lower portion, a pad of soft or yielding material placed in the upper opening and forming the bearing-surface forthe hammer in drawing a nail, and a screw or pin for retaining the pad in place, substantially as described.

4:. Ahammer-headhavingaprojectionfrom the side opposite the handle-socket, said projection having its outline in general conformation With the outline of the claw portion and terminating abruptly at the end toward the hammer portion, said projection being provided with a socket having thin edges, and a pad secured in said socket and overlapping the said thin edges, the projecting and overlapping portion of the pad being substantially flush with the surface of said projeetion :near the claw portion and gradually increasing in thickness toward the abrupt termination of said projection.

In testimony Whereof I affix my signature in presence of two witnesses.
