HAMMER.
SPECIFICATION forming part of Letters Patent No. 711,206, dated October 14, 1902.
Application filed November 23, 1901. Serial No. 83,402. (No model.)
To all whom it Til/(by concern:
Be it known that I, JOHN JAY GREEN, a citizen of the United States, residing at Boonton, in the county of Morris and State of New Jersey, have invented certain new and useful Improvements in Hammers, of which the following is a specification, reference being had therein to the accompanying drawings.
My invention relates to improvements in hammers, and refers particularly to what are known as claw-hammers; and the object of my invention is the provision of a clawhammer which will be of inexpensive and durable construction and by means of which a nail can be quickly withdrawn without damage to the body of the nail or to the wood from which the nail is removed.
Vith this object in view my invention consists of a hammer embodying novel features of construction and combination of parts, substantially as disclosed herein.
Figure 1 represents a perspective view of my hammer in the assumed position when first starting to draw a nail. Fig. 2 represents a similar View with the hammer taking a second grip or clench, and Fig. 3 is a similar.
view with the nail entirely withdrawn. Fig. at represents a cross-sectional View, on an enlarged scale, of the hammer-head.
My invention consists of the hammer-head A, which is formed with the socket B for attachment to the handle,with the driving portion 0, and with the single claw D, which is offset to receive the laterally-movable hinged claw E, which is preferably forced inward by means of the spring F. Also on one side of the socket portion of the ham mer-head is the naildrawing lug G, which acts, in conjunction with the hinged claw, to engage the nail-head, as is evident.
The manner of using my hammer in drawing a nail will be readily understood from the drawings and description, and it will be seen that the claws engage the head of the nail and the nail is lifteda short distance. Then the movable jaw closes against the body of the nail and grips the same between the jaws,
and the nail is thus removed without bending or damaging the wood, and thus the nail is saved and the wood is not injured and a neat working is assured. In removing a nail with the lug on the side of the hammer-head it is simply necessary to force the lug G under the head of the nail (the head being partly out of the wood) and lift the nail out after the manner of an ordinary rigid clawhammer, the lug G and claw E effecting this end. It will be apparent that the claws pass under the head of the nail and the claws lift the nail a short distance. Then the body of the nail is gripped to the point wherethe nail has been raised, the lateral spring-claw biting against one side of the nail-body and the rigid claw biting against the other side of the body, when the nail is lifted farther and the body is gripped again in the same manner and the nail lifted without damage to the nail or wood, as will be appreciated. It will be understood that the spring which forces the hinged jaw or claw inward is of sufficient tension to cause the claw to impinge firmly against the nail and with the rigid jaw clamp the body of the nail tight and enable the easy withdrawal of the nail.
I claim 1. A hammer consisting of the head formed with a rigid jaw or claw and a parallel-movable jaw or claw acting in conjunction with the rigid claw to grip the nail-body to remove the nail.
2. A hammer having its head formed with a rigid claw and a parallel-arranged laterallymovable claw acting with the rigid jaw to grip the body of a nail to remove the nail.
3. A hammer having its head formed with a rigid claw and a movable spring-actuated jaw for clamping the body of a nail for removing the nail.
4. A hammer having its head formed with a claw and offset or shoulder and a movable jaw resting in the offset or shouldered portion of the head. i
5. A hammer having a rigid claw, and a movable gripping-claw, and a lug on one side of the head acting in conjunction with the movable jaw to engage the head of a nail.
6. A hammer having a rigid claw and formed with a shoulder,a movable claw seated in the recess of the head and pivoted thereto, and a spring for causing the movable claw to grip.
In testimony whereof I al'fix my signature in presence of two witnesses.
JOHN JAY GREEN.
