TOOL.

Specification of Letters Patent.

Patented May 15, 1917.

Application filed. October 5, 1916. SeriaI No. 123,958.

To all whom it may concern Be it known that I, Sco'r'r THOMPSON, a citizen of the United States residing at Potlatch, in the county of Latah and State of Idaho, have invented new and useful Improvements in Tools, of which the following is a specification.

The invention relates to tools and more particularly to the class of hammers.

The primary object of the invention is the provision of a hammer wherein the head thereof carries an adjustable fulcrum which can be held in its adjusted position so that nails may be readily and conveniently extracted with despatch by the use of the hammer irrespective of the length of the nails.

Another object of the invention is the provision of a hammer of this character wherein the construction thereof is novel in form so that it may be used in the ordinary manner for driving nails or the like and also to permit the extraction of nails or the like in an easy manner.

A further object of the invention is the provision of a hammer of this character which is extremely simple in construction, thoroughly reliable and efficient in its purpose, readily and easily adjusted and inexpensive in manufacture.

Other objects will be in part obvious and in part hereinafter set forth.

The invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereinafter described, and the scope of the application of which will be indicated in the appended claims.

In the accompanying drawings:

Figure 1 is a side elevation of a hammer constructed in accordance with the invention;

Fig. 2 is an edge elevation thereof;

Fig. 3 is an end view looking toward the head; Fig. 4 is a fragmentary transverse longitudinal sectional view; and Fig. 5 is a transverse sectional view taken through the head and adjusting nut.

Similar reference characters indicate corresponding parts throughout the several views of the drawings.

Referring to the drawings in detail, the hammer comprises a head 5 formed, as usual, at one side with nail extracting claws 6, while at the opposite side is a striking nose 7, and the body of this head 5 is formed with a reduced flattened shank or handle extension 8, on opposite sides of which are located cheek sections 9 which are co-extensive with the length of the shankor handle extension and are fastened thereto through the medium of transverse rivets 10 which are passed through the extension 8 and the sections 9 as shown, said sections and extension being designed to constitute the handle of the hammer.

Formed centrally in the head 5 and open ing through the outer end thereof is a guideway in which is fitted a fulcrum slide 12 having at its outer end an enlargement 13 forming the fulcrum tip or end of the slide 12 and this enlargement 13 is normally countersunk within the head 5 to be flush with the outer end thereof.

The slide 12 for a major portion of the length is threaded for the adjustable engagement thereon of a peripherally knurled adjusting nut 14- which works in a suitable recess 15 therefor, and which is formed in the body of the head 5 so that the nut 14 will have its periphery exposed for permitting hand manipulation thereof. On the turning of the nut in the slide 12 can be adjusted and when extended lengthens the head so as to serve as a fulcrum when extracting a nail by the claws 6 of said head.

It will be apparent that the slide 12 will be held in any adjusted position when ex tended or when moved fully within the guideway of the head.

Formed in one wall of the guideway 11, longitudinally thereof, is a groove 16, while fixed in one end of the slide 12 is a pin 17 which projects into the groove 16 so as to limit the movement of the slide when adjusted by the nut 14 inwardly or outwardly relative to the head.

From the foregoing description, taken in connection with the accompanying draw ings. the construction and operation of the herein described tool will be readily apparent, and, therefore, a more extended explanation has been omitted.

Having thus described my invention, I claim:

1. In a tool, a nail extracting element having a slideway opening through the outer end thereof, a fulcrum slide movable within the slideway and embodying a threaded slide having an enlarged end portion normally countersunk within the outer end of the head. a knurled nut operatively associated with the threaded slide at a point in its length whereby the turning of said nut will effect an adjustment of sa-id'slide, said nut being exposed at opposite sides of the head, and means for limiting the sliding movement of said slide.

2. In a tool, a nail extracting head'having a slideway opening through the outer end thereof, a fulcrum slide movable within the slideway and embodying a threaded rod having an enlarged end portion normally countersunk in the outer end of the head, a

sides to expose said nut, one Wall ofthe slideway .being longitudinally slotted, andia pin carried by one end of the rod and mo?- able Within the slot to limit the adjustment of the rod; V V V In testunony whereof I affix my signature.

soo'rT THOMPSON.
