NAIL-FULLER.

Application filed December To all whom it, may concern.

Be it known that we, CHRISTOPHER J. Roxori and EDWARD D. VVooD's, citizens of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Nail-Pullers; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to an improvement in that class of nail pullers having gripping beaks adapted to enter the wood under a nail head and extract the same, and it consists in certain details of construction, among which may be incidentally mentioned auxil iary means located outside of the gripping beaks whereby a nail, too long to be extracted by said beaks, can be entirely extracted by said means. Further, in'ofisetting the beaks so that the operator can more readily see the nail head and thus locate the beaks in proper relation thereto, and, further, in providing means whereby the beaks are prevented from being brought in forcible contact with each other when said beaks accidentally slip from a nail head.

Referring to the drawings: Figure 1 represents a side elevation of the nail puller closed, and broken view of the shank and plunger; Fig. 2 is an end elevation looking in the direction of arrow a of Fig. 1, and broken view of the shank; Fig. 3 is a side elevation showing the auxiliary extractors in the act of extracting a nail too long for the gripping beaks; Fig. 4: is a detail view of the stationary jaw and broken view of the shank; F ig. 5 is a detail view of the loose jaw and broken view of the tail piece; Fig. 6 is a modified construction of the auxiliary extracting means in the act of extracting a nail, and broken view of the shank and tail. piece; Fig. 7 is another modification of the auxiliary extracting means which consists in providing the loose jaw with a claw; and Fig. 8 is a broken detail view of the claw looking in the direction of arrow 6 of Fig. 7.

top of the rod, and is used in delivering a blow on said rod'to force the gripping beaks, into the wood around a nail head.

5 is the loose member having the gripping beak 6 and is 'journaled on the connecting bolt 7 and having the tail piece 8 to form a fulcrum or leverage for extracting a nail when in the grip of said beaks or auxiliary extractors, presently to be explained.

The gripping beaks are offset to one side of the general construction, Fig; 2, so as to give the operator a clear view of the gripping beaks and a nail head, so that said beaks can be properly located with respect to the nail head before the downward blow is given by the plunger, or other like means, to force the beaks in the wood preparatory to the engagement of the beaks with the nail head, and thus avoid the necessity of making useless attempts to properly locate the nail head and unnecessarily defacing the surface of the wood especially undesirable in floormg.

The auxiliary extracting means shown in Figs. 1 to 5, inclusive, consists of the projection studs 9 on the loose member, and a similar projection or stud 10, on the stationary member.

The operation of nail pullers of this class is too well known to require a detailed description of such operation, but it may be simply stated that when the gripping beaks are forced into the wood 011 each side of a nail head, the handle portion is pulled in the direction of arrow 0, Fig. 1, and with the tail piece 8 as a fulcrum the nail is extracted. When, in the case of nails or spikes too long to be fully extracted by the leverage provided by said tail piece, the auxiliary extracting means or grippers 9 and 10, Fig. 3, are utilized as follows: The limit of operation of the gripping beaks will have extracted the nail 11 far enough to have brought it within the embrace o f the auxiliary grippers 9 and 10, and the instrument is then rocked back and forth and by a ratcheting process the nail is fully withdrawn. In other words, when the tool is rocked in the direction of arrow 0, Fig. 1, the nail will be firmly in the grasp of the auxiliary grippers 9 and 10, and when rocked in the opposite direction, the grip will be loosened in order to take hold of the nail lower down, and this operation is repeated until the nail Mama These auxiliary grippers perform another very important function, viz.: to prevent the gripping beaks'3 and 6 clashing together when they happen to lose their grip on a nail head in the process of extracting the same It frequently happens that a nail head will break ofi, or the --'gripping beaks will slip therefrom during the pulling operation and,

' that the parts- 9 prevent the points of the gripping beaks 9 unless protected, will clash to'gether and invariably break; It will befnoted-Fig. 1 and 10 will engage and thus and 10 coming'in contact with each other under any circumstances, The shoulder 8 serves to' limit theopening of the gripping beaks. p

The'modified construction shown in Fig. 6 consistsinsimply extending the loose member to form the lateral projection 12,

-. which, together with the nose portion 13 of the fixedmember 1s, willprovide the necessary auxiliary-extractingmeans for the nail 14. This is merely shifting the auxiliary extracting means from the central position shown in the other previously described views to theposition shown" in Fig. 6, but

It will be understood that, while the auxiliary extracting grippers 9 and 10 also serve the purpose of separating the points of the 3 and 6, under the circumstance above mentioned, the means to effect this separation could readily be located outside of these auxiliary grippers. It will the shank 2 can be of any desired length and connected with any other driving means desired.

Having thus described our invention, what we claim is:

A nail puller comprising a stationary member having a shank, a loose member having a tail piece and pivotally supported to the stationary member, each member having gripping beaks opposed to each other and in alinement with the axis of the shank, each member having gripping means integral therewith and laterally located with respect to the grippmg beaks and the axis of the shank and adapted thereby to extract a nail that has been partially Withdrawn by the beaks.

In testimony whereof we afiix our signatures in presence of two witnesses.
