Filed Nov. 27, .1956, Ser. No. 624,598 3 Claims. (31. 254-22 My invention relates to improvements in combination tools of the combined hammer and nail puller type.

The primary object of my invention is to provide a well-balanced hammer having a handle equipped with a nail starter puller for starting a nail from fully driven position and another nail final puller for completely pulling the started nail, the hammer providinga long lever for fu'lcruming operation in pulling a nail with either puller and the handle comprising sections each carrying one 'of the pullers and which are separable to provide a shorter lever for operating the puller carried thereby in restricted spaces.

Another object is to provide a nail puller adapted to be placed over a nail head and to snap under the nail head for pulling the nail.

Still another object is to provide a nail puller especially constructed for driving under an embedded nail head and having an anvil thereon for striking by a hammer to drive the puller.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a view in side elevation partly in section of my improved hammer and nail puller;

Figure 2 is a fragmentary enlarged view in longitudinal section taken on the line 22 of Figure 1;

Figure 3 is an enlarged view in cross section taken on the line 3--3 of Figure 1;

Figure 4 is a fragmentary enlarged view in longitudinal section taken on the same line of Figure 1 as Figure 2 and illustrating the manner in which the final puller is placed over a nail head;

Figure 5 is a fragmentary enlarged view in longitudinal section taken on the same line of Figure 1 as Figures 4 and 5 and illustrating how the final nail puller is operated in pulling a nail;

Figure 6 is an enlarged fragmentary view in longitudinal section partly in side elevation illustrating the handle section carrying the starter puller detached from the other section;

Figure 7 is an enlarged view in bottom plan of the starter puller;

Figure 8 is an enlarged fragmentary view in front elevation of the starter puller and the handle section carrying the same; and

Figures 9 and 10 are fragmentary enlarged views in side elevation illustrating the manner in which the starter puller is operated.

. in the widened portion both coplanar with the head 5, and said section 3 flares rearwardly from the widened portion 9 and is polygonal in cross section behind said portion 9 to prevent slippage and turning in the hand, and is provided with a rear 'axial bore 13 therein and a lateral bore 15 at the front end 17 of said bore 13 all for a purpose presently seen. The slot 11 is substantially rectangular and extends into the head 5 with a straight front end 19 and stepped notches 20 in its rear end 21.

A rectangular nail puller dog 23 in the slot 11 having a flat top 25 is pivoted on a pin 27 anchored in the widened portion 9 and transverse thereto and has a rear end 29 facing and spaced from the notches 20.

The dog 23 is swingable in one direction, clockwise as viewed in Figures 2, 3, 4 and 5 in opposition to a coil spring 31 on the pin 27 having its opposite ends suitably connected to the portion 9 and dog 23. The front end of the dog 23 engages the front end 19 of the slot 11 and prevents swinging of said dog 23 in the opposit hammer is moved downwardly, with the top side 25 of the dog 23 uppermost, to press the rear end portion of the dog 23 against the head 33 of a partly pulled nail 35, as shown in Figure 4, the rear end 29 of said dog 23 will swing upwardly to permit the nail to pass upwardly through and above the slot 11 and said end will then snap under the head 33 of the nail under the influence of the spring 31 to grip said nail between said dog and one of the notches 20 selected in accordance with the diameter of the nail. Then the hammer may be fulcrumed upwardly on the head 5, as shown in Figure 5, and the rear end 29 of said dog 23 and the widened portion 9 at the selected notch 20 will cam against the nail to pull the same.

The rear handle section 7 comprises an elongated Wooden hand-grip portion 37 having side edges 39, 41 concave to fit the hand, a straight rear end 43 having a beveled rear corner 45 and an axial rod 47 extending therethrough out of said section and slidable into the bore 13 to detachably attach said sections 3, 7 together.

A locking pin 49 Working in a transverse blind bore 51 in said rod is backed by a coil spring 53 in the bore 51 to enter the bore 15 to lock said handle sect- ions 3, 7 attached and is depressib-le to unlock said sections 3, 7 for detachment. A cross pin 55 extending through the hand-grip portion 31 and the rod 47 with upset ends 57 secures said portion 31 and rod 47 together. The starter puller will now be described.

An elongated combined claw and anvil member 57 is welded centrally thereof, as at 59, to the rear end of the rod 47 opposite the rear end 43 of the hand-grip portion 37 at a right angle thereto. The member 57 has a hollow front end 59, for the purpose presently seen and a transversely flat bottom 61 longitudinally convex for rocking on a plank and which is V-notched at the front end of said member, as at 63, so that said member 57 includes a front end claw for straddling a nail beneath its head. The rear end 65 of the member 57 pro vides an anvil 67 spaced from the bevel corner 45 of the hand grip portion 37 clear thereof for striking with a driving implement.

In operating the starter puller, with the handle sections 3, 7 attached, the member 57 is driven by hammer blows on the anvil 67, as illustrated in Figure 9, to drive its front end 59 under the head 69 of a fully driven, or embedded nail 71 until the V-notch 63 straddles the nail and said head 69 enters the front end 59. Then by grasping the head 5 and using the handle 1 as a long lever the member 57 may be rocked vertically on its bottom, as shown in Figure 10 to partly pull a long nail for complete pulling by the described final puller.

Patented Oct. 25, 1960 When the rear handle section 7 is detached as shown in Figure 6 the hand-grip portion 37 rod 47 and member 57 may be used as a separate short handled nail puller for either partly pulling long nails or completely pulling short.

nails in the manner previously described. Also when the rear handle section 7 is detached the handle 1, will be shortened and the front handle section 3 will provide a short handle for operating the final nailv puller, as described, or for weilding the hammer head 5.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.

What is claimed as new is as follows:

1. In a nail extractor, the combination of an elongated handle, a hammerhead provided at one end of and projecting laterally to both sides of said handle, said handle being provided adjacent said hammerhead with a slot having a first end wall at the hammerhead and a second end wall oriented longitudinally in the direction of the handle,

a pivot pin provided in the handle and extending trans-- versely of said slot intermediate the ends of the latter and parallel to the longitudinal axis of the hammerhead, and

'4 a nail gripping dog of an elongated configuration mounted intermediate the ends thereof on said pivot pin in said slot, one end of said dog being engageable with the first end wall of the slot whereby to permit partial rotation of the dog on said pivot pin in one direction only and the other end of the dog being spaced away from but cooperating with the second end wall of the slot to grip a nail therebetween.
