Scheurer, Mankato, lidinn. Application June 26, 1936, Serial No. 87,511 1 Claim. (01. 254-26) This invention relates to hammer attachments and has for the primary object the provision of stantially U-shaped body portion 5 providing a a simple and inexpensive device of this character curved fulcrum face ‘i. The substantially U which may be easily and quickly adapted to a shaped body adjacent one end has an opening 8 5 hammer head of the claw type to provide to the through which extend the claws 2 of the hammer. head a fulcrum which will permit the extraction The other end of the body 6 abuts the body 3 of 5 of nails without danger of bending or otherwise the hammer and is yieldably held thereagainst by damaging said nails so that they may be again a contractile spring 9, one end of which is pivotal ly connected to the body 6, as shown at In, while used. the opposite end is provided with a hook or eye i i 10 With these and other objects in view, this in to engage a notch l2 formed in the body 6.

For a complete understanding of my invention, the hammer the body 6 is brought into engage ment with the board or like device in which the reference is to be had to the following descrip nail is driven. The claws 2 are placed to engage tion and accompanying drawing, in which the head of the nail with the head of the nail Figure 1 Ba side elevation, partly in section, spaced from either end of the claws.

Figure 2 is an end view showing the attach ment. Figure 3 is a view similar to Figure 2 showing 25 the other end of the attachment. C15 Referring in detail to the drawing, the numeral I indicates a conventional type of claw hammer. including the usual claws 2 formed integral with the body 3. The striking portion 4 is integral with the body portion 3, the latter having the usual eyelet to receive the handle 5. A hammer oi this type when employed for extracting nails usually brings about bending of such nails ren dering them un?t for further use. In order that a hammer of this kind may extract nails without danger of mutilation or bending, the nail must be pulled in a straight endwise direction and in order that a pull be made upon the nail in this manner my attachment is employed and consists of a sub— crum on the body 6 exerting a straight endwise 20 pull upon the nail so that the nail will be ex tracted without bending or mutilating in any Way. As the hammer swings on the body 6 as a fulcrum the nail and claws may have a relative movement which will prevent the nail head from twisting off. 2r Having described the invention, I claim: A hammer attachment comprising a substan~ tialiy U-shaped body presenting a curved ful~ crum face and having an opening adjacent one end to permit claws of a hammer head to pass 30 therethrough with the other end of the body bearing against the head of the hammer, said last named end of the body having an aperture adjacent one edge and a notch adjacent its op posite edge, and a contractile spring passing about 3:‘ the head of the hammer and having one end per manently received by said aperture and its other end detachably received by said notch.
