1 Claim. 1
This invention relates to hammers and particularly to those which are designed with means for pulling nails.
Hammers are in conventional manner equipped with a head which is provided with a poll and a claw disposed in opposite directions. It has also been proposed to provide a second or auxiliary claw, which, however, is disposed in a direction opposite to that of the first claw and also on the side of the longitudinal axis of the hammer at which the poll is arranged. The fingers of the second claw are formed by a recess provided therebetween, in order to provide the possibility of moving the stem of the nail in the recess during the extraction, so that bending of the nail is obviated. This second claw of this known construction is positioned adjacent to and directed toward the poll which makes the second claw inoperative.
It is, therefore, one object of the present invention to provide a hammer, the head of which is equipped with two claws disposed on one side of the longitudinal axis of the hammer and with a poll disposed on the other side of said longitudinal axis.
It is another object of the present invention to provide a hammer with a second claw on its head, the inner surface of which claw increases its perpendicular distance from the head towards the end of the claw.
It is still another object of the present invention to provide a hammer with two claws, one of which permits of using the common outer surface of the two claws or the poll of the hammer head as fulcrum for the extraction of nails.
With these and other objects in view which will become apparent in the following detailed specification, the present invention will be clearly .understood in connection with the accompanying drawings in which:
Figure 1 is a side elevation of the hammer head;
Fig. 2 is an end view thereof;
Fig. 3 is a bottom plan view of the hammer head;
Fig. 4 is a side elevation of the hammer head with the second claw extracting a nail and using the poll as fulcrum;
Fig. 5 is a side elevation of a second embodiment of the hammer head, and
Fig. 6 is a top plan view of the hammer head shown in Fig. 5.
Referring now to the drawing and particularly to Figs. 1 to 4, the hammer comprises a head I and a handle 2. One end of the handle 2 is reclaw 1 operative. second claw I would be bent towards the poll 4,
ceived in an eye 3 provided in the head I an' secured therein by conventional means as a pin, a wedge or the like (not shown) The head is formed with a poll 4 and a claw 5 disposed laterally in opposite directions from the longitudinal axis of the hammer. The end of the claw 5 is bifurcated to form two fingers 6 in order to provide means for lifting the head of a nail in conventional manner. A second claw 1 is formed on the same side of the longitudinal axis of the hammer on which said first claw 5 is disposed, however, extending in a direction to and terminating substantially at the longitudinal axis of the hammer. The second claw l is also bifurcated to form two fingers B for the same purpose as described for the first claw 51. The two claws 5 and 1 form a common curved outer surface 9 along which the fulcrum travels in the extraction process of a nail by either claw 5 or I. The inner surface 10 of the second claw 1 is also curved and the distance from the head increases in axial direction towards its end, which is an essential feature in order to make the second If the inner surface of the the latter would not permit of gripping ahead of a nail. If, however, disposed in accordance with the present invention, not only is such gripping possible, but the second claw I also provides the possibility of using it in two ways, namely, as stated above, with points on the curved outer face 9 as fulcrum or with the end of the poll 4 used as fulcrum. The latter use brings about a relatively long turning arm between the nail and the fulcrum and thus results in a very powerful extraction device.
Referring now to Figs. 5 and 6 of the drawing, the second embodiment of the present invention comprises essentially the same elements as disclosed with the first embodiment. While, however, the first embodiment forms the second claw integrally with the first claw of the head, the claw I, in accordance with the second embodiment, is removably secured to the hammer head I'. a poll 4' and a claw 5' disposed laterally in opposite directions. The side faces of the claw 5' are offset and form an extension II which has a plurality of transverse holes H. A second claw 1 is equipped with a longitudinal slot l3 complementary to said extension II and with transverse holes M which are aligned with the holes l2 of the extension when the second claw I is in mounted position. Upon mounting the second claw 1 by inserting the extension ll of Thus the hammer head I comprises retaining it in position by rivets, screw bolts (not shown) or the like, the outer surface 9 of both claws 5' and I forms one continuous curve and the innersurface III of the claw 1 is then disposed in the same manner as described with the first embodiment to render it operative.
While I have disclosed two embodiments of the present invention, it is to be understood that these embodiments aregiven by example only and not in anylimiting sense, the scope of the invention being determined by the objects and claim.
A hammer comprising a head and a handl e,
said head comprising a center portion having an 1 eye extending therethrough, s aid eye receiving one end'of said handle, a poll extending from one 4 being disposed in opposite direction to each other and said first claw being disposed in the rearward direction from said center portion and said second claw being disposed in the direction of said poll and terminating substantially at the longitudinal axis of said hammer and the distance from the inner surface of said second claw to the center portion of the head increasing towards the end o f said second claw. a COUVARIS J.
