To all whom it may concern.

Be it known that I, HARLON A. CLIFFORD, a citizen of the United States, residing at Greenfield, in the county of Franklin and State of Massachusetts, have invented a new and useful Nail Puller, of which the following is a specification. This invention relates to nail pullers, and has for an Object the provisionv of means for readily drawing a nail from a structure by employing an ordinary claw hammer; or when the nail is a relatively large one by employing a bar or a similar device in connection with the device;

vide a nail puller of generally improved construction, whereby, the device will be simple, durable and inexpensive in construction, as well as convenient, 'practical,efficient and serviceable in its use. i

' \Vith the above and other objects in view which will appear as the description proceeds, the inventionresides in the combination and arrangement of parts and in the details of construction hereinafter'described and claimed, it being understood that within the scope of what is claimed, changes in the precise embodiment" of the invention shown can be made withoutdeparting from the spirit of the invention.

Referring to the drawings, there are shown opposed body members 1 "and 2 which are pivotally united by means of a rivet or other securing device 3. The body member 2 has gripping jaw 1 extending from one a terminal thereof, and, a fulcrum member or foot 5 cxtendsfrom the opposed terminal of the body member 2. The outer or operative face 6 of the-foot member 5 is shaped to define a compound curve, the curves of the least radii being. disposed adjacent the claw 4: and the curves of the greatest radii being positioned away from the claw 4. j

In use, the device is'so positioned that the opposed jaws 4 and 7 engage the headof the nail N, and then the upper end of the body member 1 is struck with a hammer which drives the points of the jaws4' and 7- under the head of the nail thereby sehammer is placed in the recess 8, and the curely gripping it. Now the claw :of the] convexed portion of, the claw, engages the upper face :of the arm 9. In this position the hammer handle is. gripped and moved in the direction indicated by the arrow, which action causes the jaws 4: and 7 to securely hold the head of the nail, and continued movement inthis direction with-.

During the initial movement the device will be fulcrumedon the foot 5.at a point adjacent the jaws 4 and 7, but as the nail is withdrawn from the material the'fulcrum point is shifted to points remote from the jaws and allows the nail to be. drawn entirely from the material M. 1 Y The invention has been illustrated in its v V q The arm 9 is made relatively long so that hammers of various shaped claws may be; I
