HAMMER Filed 001:. 26, 1932 Patented Aug. 15, 1933 UNHTED STATES Application October 26,

4 Claims.

The invention relates to a hammer and particularly to a nail holder for a hammer.

The principal object of the invention is to construct the head of a hammer with means whereby a nail of any size may be held in driving position, be initially set in place by the use of one hand, beyond the position at which the nail would be normally placed into position by the employment of two hands in the usual manner of setting a nail, whereupon the nail may be finally driven into its ultimate position.

One of the objects of the invention is to con struct the nail holding means so that it will firmly, yet releasably, hold the nail in position with relation to the head of the hammer and prevent the nail from getting out of position or flying before it is placed at the point where it is to be driven.

Another object of the invention is to construct the head of a hammer with a flexible spring clip which is firm enough to hold any size of nail, and in many cases brads, screws and the like, so that they may be initially placed in position by the aid of an auxiliary striking face of the hammer head, and subsequently driven into place by the hammer employing the principal striking face.

It is another object of the invention to construct the hammer head with an opening capable of receiving nail heads of various sizes, immediately adjacent the auxiliary striking face and having the auxiliary striking face serrated, milled or knurled to prevent displacement or slipping of the nail head while the nail being r held by the clip and initially set in position ready to be finally driven into place.

A further object of the invent-ion is to construct the hammer head with an integral depending portion which is slotted in a wedge shape in its lower end to hold one end of the spring clip therein with the aid of a wedge in said slot.

An additional object of the invention is to form the slot and the wedge in a manner to permit of the ready removal of the clip in case it should be injured, broken or destroyed.

Another object of the invention is to form the integral nail holding means with a groove which with the clip and the serrated auxiliary striking face keeps the nail in proper alignment with the head of the hammer in order to properly initially place the nail in the desired position.

In case it is desired to lessen the liability to injury and destruction of the nail clip, a

1932. Serial No. 639,559

modified construction embodying a metal clip protecting shield which may be placed in position and held permanently as by spot welding, may be employed.

The invention will be best understood by reference to the following description and the accompanying drawing in which the invention is illustrated toge her with the modification thereof employing the clip shield or protector, and it will be understood that further modifications of the structure may be made without departing from the spirit of the invention as set forth in the appei'ided claims.

Figure 8 is a side elevational view of the Wedge adapted to hold one end of the spring in its slot,

and

Figure 9 is an end elevation of the wedge of Figure 8.

The invention is illustrated in connection with 100 the ordinary hammer head but it will be understood that it may be applied to all forms of hammer heads and in fact, to all forms of hatchet heads or any instruments for driving all forms and sizes of nails.

As shown the hammer head 10, which has the handle 11, is constructed with the'integral depending portion 12. The hammer head 10 may be formed with the integral depending portion 110 12 or the depending portion, as an independent unit, may be forged or welded to the hammer or hatchet head.

The depending portion 12 is provided with the nail groove 13 which extends from the outer edge of the depending portion 12 to a relatively large nail head opening 14. The groove 13 preferably has two

faces

15 and 16, at right angles to each other, against which the nail 17 is held in position by the leaf spring 18.

A striking portion 19 of the depending portion 12 is integral therewith and forms a part of the hammer head 10. The striking portion 19 has its face provided with serrations, milling or knurling 20, so as to assist in holding the head of the nail 17 against sliding or slipping on the surface of the striking portion 19 and firmly between the spring 18 and the depending portion 12, in the groove 13.

It will be understood that the opening 14 in the depending portion 12 should be large enough to receive any size of nail head which is to be placed in position and driven by the hammer. It will also be understood that the opening 14 may be made of such size that it will assist in the creation of the proper balance for the hammer head.

The depending portion 12 is provided with the

sides

21 and 22 which converge toward the lower face 23 of the depending portion 12. A wedge shaped slot 24 is provided in the lower end of the depending portion 12 and a wedge 25 is normally driven into the slot 24 to hold the bent and lower end of the spring 18 in position.

The slot 24 is constructed with the curved walls 26 as best shown in Figures 1 and 2 of the drawing. The wedge 25 is formed with the curved inner edges 27 so as to fit in the curved slot 24. In the event that the spring 18 should be broken the spring could be removed from its position in the slot 24, where it is held by the wedge 25, by striking against the wedge 25 with a suitable tool, the end of which may be placed in the indent 28, and the wedge 25 forced against the curved wall 26 and out of the slot 24, thus releasing the end of the spring 18 from within the slot and from the depending portion 12. A new spring 18 may thereupon be placed in position in the slot 24 by having its lower end inserted in the slot and the wedge 25 returned into position in the wedge shaped slot 24, securing the end of the spring 18 in place.

The spring 18 is preferably bent to the shape best shown in Figure 3 having its principal portion lying substantially parallel with the converging side 22 ot the .depending portion 12, and having its outer end terminating in the roll 29, which assists in preventing the spring from being caught in clothing or injuring the user.

It will also be understood that the spring 18 may be made of fiat leaf spring material, of any desired length, width or thickness, to hold the nail, brad or screw in the groove 13, and against the hammer head in such a way that the nail, brad, or screw, may be initially placed in the position in which it is to be ultimately driven.

As shown the nail is in direct alignment with the upper wall 15 of the groove 13 and the lower line 30 of the rounded striking head .31 of the hammer. The nail may then be inserted in the place it is .to be ultimately driven, the nail being first driven by means of the striking portion 19, having the auxiliary striking face 20. There- 'upon the hammer may be drawn away from the nail, the nail being released from the action of the spring 18, and from the groove 13. The head of the nail will pass from the aperture 14, and the nail may then be driven to its ultimate position by striking it with the hammer head or striking face 32.

It will thus be seen that two striking faces are employed in driving the nail into position, the first being the auxiliary stri ng face 20, which has the serrations or milling, when the nail is first placed in position, and the second being the striking face 32, when the nail is driven into its ultimate position after being released from the action of the spring 18, and from the groove 13.

the modified form of hammer illustrated in Figures 5, 6 and '7, the construction and mode of operation identical with the hammer and the holding means illustrated in Figures 1 to 4, inclusive, except for the addition of the metallic shield or protector 33. The shield 33 is preierably made of a relatively thick piece of metal, wide enough to extend beyond the spring 18 on both sides thereof as shown at 34 and 35 in Figure 5. The shield or protector 33 is also provided with the upwardly extending portion 36 which is narrower than the lower portion of the shield and which serves to shield and protect the upper portion of the spring 18. The upper portion 36 of the shield or protector is provided with side extensions or

flanges

37 and 38, as shown in Figure '7. These

flanges

37 and 38 with the extension 36 provide a space or pocket within which the spring 18 may move when the sp ing is acted upon by the nail 17, when it is placed in position in the groove 13.

The shield or protector 33 may be secured in place on the depending portion 12 by means of spot welding as shown at 39 and 40 in Figure 5. It will be noted that the shield or protector '33 is also provided with the opening 41 which extends through the shield or protector '33 to permit the insertion of the spring 18. It will be seen that the spring 18 may be readily inserted in the slot 24 and the opening 41.

It will be apparent that the shield or protector 38 need not be put on every hammer head employing the invention but being a separate unit may be spot welded upon the depending portion 12 as may be desired:

Having thus described the invention what I claim and desire to secure by Letters Patent is:

1. In a hammer the combination of a hammer head and 3. depending nail supporting member integral therewith, said nail supporting member comprising a spring one end of which is secured in a slot in the depending portion, a right angled groove extending longitudinally in the side of said depending portion and in alignment with the lower edge of the hammer head said groove being constructed to hold the nail firmly in position against a side wall of the depending portion and the lower face of the hammer head with the aid of said spring, said groove terminating in an enlarged metal surrounded aperture adapted to receive any sized nail head, one wall of said aperture constituting the striking face of said depending portion.
