JAWED TOOL. APPLICATION F|LED APR. 9, 1921.

UNITED STATES PATENT OFFECE.

JOHN HENRY RIDINGS, OF COAL CITY, ILLINOIS:

Application filed April 9,

T 0 all whom 52 may concern:

Be it known that 1, JOHN HENRY RrorNes,

a citizen of the United States, residing at Coal City, in the county of Grundy and State of Illinois, have invented certain new and useful Improvements in Jawed Tools, of which the following is a specification.

My invention relates to improvements in jawed tools, such for example as pliers, pinchers, tongs, and the like. The invention relates more particularly to improvements in the jaw portions of the tool through the provision of an improved pivoted or rocking aw mounted upon and detachably secured to one of the jaw members and adapted to cooperate with the opposed or toothed jaw and to rock upon its pivot or point of oscillation to conform to the form and plane of the article being grasped and this independently of the particular position or angleof the opposing jaw of the tool.

The primary object of the invention is to provide a generally improved tool of this class whichwill not only be simple in construction, cheap of manufacture, and efficient in use, but one in which the jaws will more elfectively conform to and grasp or hold an irregular or headed article such as a spike, belt, or the like.

With the above mentioned and other ends in view, the invention consists in the novel construction, arrangement, and combination of parts, hereinafter described, illustrated in one of its embodiments in the accompanying drawings, and particularly pointed out in the appended claims.

Referring to the drawings, forming a part of this specification Figure 1, is a side elevation of a tool constructed in accordance with this invention.

Fig. 2, an edge view of the same.

Fig. 3, an edge view of one of the handled jaws, detached and illustrating the in ner or toothed portion of the jaw.

Fig. 4, a similar view of the complemental or opposed handled jaw member, the supplemental pivoted or rocking jaw being detached to illustrate the mounting therefor.

Fig. 5, a side elevation of the supplemental or rocking jaw detached.

Fig. 6, a view of the inner or toothed side thereof.

Fig. 7, a view of the outer or recessed bearing portion thereof and illustrating more particularly the transverse bearing JAWED TOOL.

Specification of Letters Patent. Patented Aug. 29, 1922 v 1921. Serial NO. 459,306.

therefor for being seated on the bearing head or statlonary portion of the mainjaw.

like parts throughout all the figures of the drawings.

In the drawings 1 have shown my improvements applied to or incorporated in a jawed tool of the adjustable jaw plier type comprising, in the present instance, the usual pivoted members consisting of handles Fig. 8, a fragmentary side elevation of the tool with the aws and handles extended 1, pivotally connected by means of'apivot bolt or member 2, and terminating in jaws 1, and 1 The jaw and handle members areadapted to be adjusted to two positions by means of the shifting slot 1, terminating in bearing openings 1 and operating in a well known and understood manner.

As a means. of enabling the jawportions' to conform to, and to more effectively grasp irregular shaped objects notwithstanding variations in the closed position of the main jaws, a supplemental pivoted or rocking jaw 33, is provided, said aw COIIIPIiSUlg the spaced terminal members 8, adapted to span the toothed portion of the aw 1, and to firmly engage with the inner and outer extremities thereof when the jaws are closed against themselves as shown in Fig. 1, of the drawings.

As a means of providing a suitable space for the rocking jaw 3, as well as mounting the same in a convenient manner the jaw 1 is provided with a cutaway portion or recess 3, on its inner side, said recess portion 3*, being provided with a bearing portion 3, in the present instance, in its specific form of an inwardly extending bearing lug (see Fig. 4) said bearing portion 3 terminating at its inner end in a transversely extending bearing groove 3 The lug or hearing portion 3 is also provided with a transverse opening 3 preferably of elongated or arcuate form as shown most clearly in Fig. 1 of the drawings.

As a means of detachably mounting the rocking jaw 3, upon the bearing portion or lug 3 and particularly as a means of relieving the attaching pin of any strain or stress, the rear side of the aw 3, is provided with opening 3 an opening or recess 3 adapted to loosely receive the bearing portion 3, and to extend over the latter, said opening or recess terminating in a transversely extending bearing portion 3, in the present instance, in the specific form of a bearing rib seated in the bearing groove 3 of the bearing lug.

As a means of removably mounting the jaw 3, upon the lug 3 and holding the parts in proper assembled position an attaching pin, such as a bearing pin, screw, or the like,

is transversely mounted in suitable openings 4 in the sides of the jaw, said pin or attaching elements 4, extending through the arcuate opening 3, so that asthe'j aw rocks 'or tilts on the bearing portion 3 the attaching pin 4:, will bemoved to and fro in the arcuate The jaw 3, has a limited rocking portion'by reason of the rear portions thereof forming stops coming into engagement with the adjacent inner sides of the jaw l".

The base ortions of the jaws 1 and 1", are provide with cutters 1 and 1, for cutting Wire nails and the like.

The rocking jaw is provided with the toothed portions'which are rounded in the center and provided with recesses 3 at the ends, said recesses being adapted to receive the heads of articles such'as nails, bolts, and the like, and as a means of holding such articles centrally the toothed portion of the rocking jawB, is preferably provided with centrally located recesses extending longitudinally'in alignment as shown most clearly in Figs. 6,*and 9, of the drawings.

Having thus described'one of the embodiments of'my invention,'wha:t 1 claim and desire to'secure by Letters Patent, is,

l. A jawed tool, comprising pivotallyconnected handled jaws, one of said jaws being recessed and spaced from the other and provided with a reduced bearing member extending therefrom, said reduced bearing member being provided with a transverse recess at its end and a transverse slot opening, and a rocking jaw having an opening receiving said reduced portion and provided with a transverse fulcrum portion seated in said groove, and an attaching pin extending through said rocking jaw and said open ing of said reduced bearing portion.

3. In a jawed tool, a pair of pivotallycon nected handledjaws', one of said jaws being provided with gripping teeth and the other being spaced therefrom and provided with a bearing lug extending towards said first mentionedjaw, an auxiliary jaw having an opening at its rear receiving said bearing lug andsupported solely on the latter, and an attaching pin carried by said auxiliary jaw and extendingthrough said bearinglug;

and adapted to rock therein with the movements of said auxiliary jaw.

In testimony-whereof I have afiixed'my signature.
