DETAOHABLE-JAW TOOL.

Specification of Letters Patent.

Patented Aug. 3, 1909.

Application filed September 17, 1908. Serial No. 41,53,529.

Be it known that l pakoneta, in the county of Auglaize and State of Ohio, have i vented certain new and useful improvements in Detachable-J aw Tools; and I do declare the following to a full, clear, and exact descri tion oi the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in pivoted tools, and comprises the production of a pivotal tool provided with means for removably securing jaws thereto.

One of the objects of the invention is the production of a pivotal tool formed with locking means for securing thereto ditlerently-eonstructed removable jaws.

Another object of the invention is the production of a removable jaw for pivotal tools adapted to be readily secured to a speciallydesigned tool by a simple spring locking arrangement.

lVith these and other objects in view, the invention consists of certain novel features of construction, combination and arrangementof parts as will be described and par ticularly pointed out in the appended claims, and in the drawings, in which- Figure 1 is a perspective view or" my iin-- proved tool; Fig. 2 is a fragmentary longitudinal sectional view thereof; 3 is a transverse sectional view taken on the line 3-3 of Fig. 2; Fig. i is a transverse sectional view taken on the line li of F 2; Fig. 5 is a detail perspective view of a re movable jaw; Fig. 5 is a detail perspective view of a set of removable jaws formed with a side cutting edge; Fig. 7 is a detail perspective view of an end cutting jaw; Fig. 8 is a detail perspective view of a wiredornr ing tool or jaw; 9 is a detail perspective view of an end-receiving gripping jaw; Fig. 10 is a detail perspective view of a side-re ceiving gripping aw; and Fig. 11 is a detail perspective view of a doubly-channeled gripping aw.

Corresponding and like parts are referred to in the following description and in all of the views of the drawings by the same reference characters.

In the drawings, 1 and 2, denote pivotal members, which are formed with jaw-carrying ends 3 and 4. A plurality of lateral 1 l Lani. L. MUELLER, a I citizen oi the United States, res1d1ng at Wapins, 5 and 3, project toward each other from the ends 3 and J1, and said pins are formed with cross heads, 7 and S. The pins, 5 and 6, are positioned midway oi the ends, 3 and i, and are recessed at their outer ends to receive the end o1 fiat springs, 9 and 10. The spring 9 and 10, are seated in longitudinal slots, 11 and 12, and extend to the terminals 0. the ends, 3 and lit; a point midway of their ends, the springs, 11 and 12, are connected to movable pins, and 14, which extend through openings, 15 and 16 formed in the jaw-carrying ends, 3 and -l-, and project interiorly of the inner faces of said jawcarrying ends. The pins, it and 13 are slightly rounded on their inner ends and are adapted to projectthrough openings, 17, formed in a removable jaw, 18. The removable aw, 16, is slightly beveled on its sides at 19 and is formed with a reduced end, 20, having an opening, 21, formed therein, said opening being substantially circular in its middle body portion and rectangular at its ends.

The removable jaw, 18, may be readily secured to the jaw-carrying ends, 3 and i, by passing the reduced end, 20, over the pin, 6 and turning said jaw on said pin so that the opening, 1?, in said jaw will register with the inwaall oro ectine end of the t pins, 13 and 14,-. W hen secured in place on the jaw-carrying ends, 3 and a, the removable jaw 18 will be rigidly loc red in place by means of the cross heads ffl'l'LiOCl on the pins, and t3, and the pins 15 and 16, and cannot, of itself, -c disengaged from aid jaw-carrying ends or turn upon the connecting pins. The springs, 11 and 12, normally press the pins, 18, 1 t, inwardly through the openings formed in the removable jaws and the lateral pins 5 and 6, which, when provided with the cross heads 7 and 8, are substantially l -shaped in cross section, may he formed integral with said jaws or threaded thereon.

The removable jaw illustrated in Fig. 5 is termed substantially tlat and the beveled ec ges, 19, of said jaw are adapted to engage tne rounded ends or the lateral pins, 5 and 6, in such manner that the turning of the removable jaws, 18, upon the T- head pins 5 and 6 will force the pins 18 and 14 outwardly so that the said jaw may readily 0ccupy its locked position.

The removable jaw illustrated in Fig. 6 is substantially the same asthe aw illustrated in Fig. 5, and designated in the description by the numeral, 18, with the exception that the face of said jaw is formed smooth and is provided with a laterally-projecting edge, 22, which is adapted to engage a similarlyformed edge on an opposing removable jaw. hen secured in place, a pair of the removable jaws illustrated in Fig. (3 is adapted to make a scissors cut in the material to be operated on.

The removable jaw illustrated in Fig. 7 is similar to the aws illustrated in Fig. 6, with the exception that the cutting edge is formed on the end of said jaw, and the cutting edges of two aws move to *ard each other with an evenly-opposing movement.

The removable jaw illustrated in Fig. 8 is formed with a rounded end and is particularly adapted to enable an operator to quickly form wires into various shapes, as by twisting and turning.

The removable jaw illustrated in Fig. 9 is longitudinally curved and formed with a plurality of ridges or corrugations and is adapted to receive round material through the end of said jaw.

In Fig. 10 a removable jaw is illustrated, which is similarly formed to the jaw shown in Fig. 9, with the exception that the groove extends laterally across the end of said aw instead of longitudinally therewith.

In Fig. 11 is illustrated a removable jaw formed with double channels which are shown to extend laterally across the end of said jaw, but as is obvious, may be arranged to extend longitudinally therewith.

It will be seen that by means 01' my invention a pivoted tool is provided which may be adapted for a wide field of use, and may be used for cutting and gripping differentlyshaped articles. It is also obvious that the differently-formed removable jaws may be quickly secured to the pivotal tool ends, 3 and 4-, and quickly removed therefrom.

From the foregoing description, taken in connection with the accompanying drawing, the construction and operation of the invention will. be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention as defined in the appended claims.

Having thus described my invention, what I claim. as new and desire to secure by Letters-Patent, is:

1. A pivotal tool having one of its ends provided with an inwardly facing T-headed pin and a lateral sliding pin resiliently forced inward on said end in combination with a jaw removably secured to the pins and said end.

2. The combination with a pivotal tool formed with a lateral pin, eta removable jaw formed with an opening arranged to receive the lateral pin, and resilient means for looking the removable aw to said pin.

3. The combination with a pivotal tool formed with a T-headed lateral pin, and a resiliently controlled projecting pin, of a removable jaw arranged to be secured in locked position on said pins.

l. The combination with a pivotal tool formed with a plurality of opposing T- headed pins, and a plurality of longitudinal slots, springs seated in the longitudinal slots, pins secured to the springs slidablv extending througi he pivotal tool, removable jaws formed with openings to receive the ends of the pins, and means for locking the removable jaws to the pins.

The combination with a pivotal tool formed with plurality of projecting T- headed pins and provided with resilientlycontrolled laterally-sliding pins, and of a plurality of opposing jaws removably secured to the ends of the tool and in locked position on the pins.

6. The combination with a pivotal tool formed with a plurality of opposing T- headed pins, plurality of removable jaws formed with openings corresponding to the form of the heads of the pins, a plurality of spring controlled laterally sliding pins arranged to project through openings formed in the removable jaws, and means for looking the removable jaws to the tool.

7. The combination. with a pivotal tool formed of a plurality of laterally-projecting pins formed with cross pieces, a plurality of sprii'ig-controlled laterally-sliding p1ns, and a plurality of jaws formed with openings adapted to receive the pins and arranged to be secured in locked position thereon.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
