HAMMER Filed July 26, 1930 INVENTOR. Austin L Jame Patented Mar. 1, 1932 UNITED STATES PATENT OFFICE AUSTIN L. STOWELL, or mew 3mm, commcrrcu'r. Assrenoa TO THE STANLEY woaxs, or m mum, commences, A. oonromrron or CONNECTICUT Application filed July 28,

This invention has to do generally with'the art of tools, and more particularly involves a novel type of hammer which is deslgned primarily for use in automobile repair work.

The curvature of the fenders and the body of automobiles, together with conditions as to the accessibility of the work, are factors now entering into repair and straightening operations, which very often preclude the use of hammers now available to the public. This is because the present day hammers are not designed to meet these varied conditions with satisfactory results. Accordingly, this invention has in view, as its primal object, the provision of a hammer of distinctly novel desi which is intended to be used in the stralghtenjng out of bent fenders, and which is of a structure adequate to meet the varied conditions as to curvature and accessibility arms, each of which is formed with curved impact faces. This head is positioned obliquely with respect to the handle, and the impact faces are reversely curved with respect to one another. As a result of this arrangement, one of the two arms will always present a curved impact face which will meet the conditions of use to which it will be subjected, particularly those of curvature and accessibility of the work. When the novel hammer hereof is used, a mechanic will, at all times, be able to work with an impact face at proper angular relationship with respect to the handle, and which impact face will also present the desired curvature, due to the reverse curve in the head. The mechanic will be enabled to use the hammer around and beneath the fenders where the wheels and design of the fenders very often interfere with repair operations of this nature.

Another important feature of the invention is the provision of a hammer of the type noted which is also capable of use as a dolly block in fender repair work. A hammer provided in accordance with the foregoing pre- 1930. Serial No. 470,884.

.cepts is peculiarly adapted. to being held tion of which will be indicated in the ap-v pended claims.

For a full and more complete understanding of the invention, reference may be had to the following description and accompany-- ing drawings, wherein:

igure 1 is a view in side elevation of a hammer head and a portion of its handle, and which head embodies the improvements of this invention.

Figure 2 is a top plan view of the head shown in Figure 1.

Figure 3 is a detailed perspective, taken from the top of the head, and

Figure 4 is a section through the head, taken about on the plane represented by the line 4-4 of Figure 2.

Referring now to the drawings, a hammer made in accordance with this invention is shown as comprising a head A and a handle B. These parts are joined together by a connection including an opening 10 formed in the head A intermediate the extremities thereof, and a reduced end 11 on the handle B. The reduced end 11 fits in the opening 10 and wedges 12 are driven therein to establish the permanency of this connectiomthis being conventional practice in this art.

The, hammer head A is preferably made from steel by drop forging, and comprises two arms, 13 and 14, which are, so to speak, reversely curved. These arms are enlarged at their extremities, as indicated at 15 and 16 to provide enlarged ends having curved im of the line, while the impact face at 16 falls on the other side. This is brought out in Figure 1.

The curved impact faces at 15 and 16 are reversely curved to provide impact faces at different angular dispositions'with respect to the handle B. This arrangement provides an impact face that will conform to the curvature of the work under varied conditions, and this feature, in combination with the oblique disposition of the head, and reverse curve of the arms, insures of the effective operation of the hammer under all conditions of accessibility.

A hammer of the type provided hereby is known in the trade as a roughing out hammer, and when a mechanic is desirous of working on the underneath side of the outer edge of a fender with one made in accordance with this invention, he ma avail of the impact face at 15 for the e ective end of the hammer. The curve of the face, together with the oblique disposition of the arm, insures ofrthe proper positioning and engagement ofthe impact face with the work, while is at an acute angle to the handle .while the other impact face is at an obtuse angle to said handle. i

2. A hammer of the character described comprising a handle, and a hammer head mounted on the handle intermediate the ends of the head, said head having reversely curved arms on the ends thereof, the impact the curve of the arm provides for the free and easy swinging action necessary to the effective use of the hammer. Now, if work is to be done on the inner edge of the fender, the mechanic will employ the impact face at 16 in the manner above described. When the hammer is to be used as a dolly block, it is held against the bottom side of the fender, with the proper impact face in position. The

.. other side of the fender is then hammered, to

widely different embodiments of this inventfon could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.

What is claimed is:

1. A roughing out hammer of the character described comprising a handle and a head disposed obliquely with respect to the handle on the plane of the axis of the handle, said head havin curved impact faces at each end thereof, sald impact faces being reversely curved so that one end of said impact faces
