No. 816,674. EATBNTBD APR. 3, 1906.




Further, I propose not UNITED STATES PATENT oFF roE.

y no. 316,674.

To all whom/ it may concern.-

' Be it known that I, QLE MEDHUs, a citize of the United States, and a resident of the city of Faribault, in the county of Rice, and the State of Minnesota, have invented certain new and useful Im rovcments in Combination-Tools, of whic 'the following is a specification, which when taken in connec tion with the accompanying drawings, forming-a part'thereof, is sufficiently clear and conciseas toenable others skilled in the-art to which it appertain's to make and use the same;

PIA particular object of -my inventionis to provide a tool having detachable and intern-.-

c liangeablefpairs of jaws, whereby agreat var etyofwork maybe done and a great vaof material operated upon with a single for a large assortment of tools, asnow used in many'trades-andoccupations.-

only to accomplish the; eb'ects stated in the preceding paragrapln, u t also to provide a tool in which the changes; or; transfers may be easily and uickly made, even by one unfamiliar with "t eoperation of'devices of this character.

, The distinctive features of my invention,

briefly stated, consist of a pair of lever-han files, a plurality of pairs ofjaws, each pair being'especially ada tedfor a different variety of work, the nove means I employ for connecting the handles to the various pairs of jaws, the'arrangement of two pairs of jaws u on-ja. sin le pair 'of shanks, and the means f r ass'e'mb g the parts into a complete tool. 3 My invention ,consists in a combinationtool embodying new and useful, features and .details of construction and the relative disposition of the severalparts, substantially as articularly described elsewhere in this specidcation, and in the legitimate combinations herein set forth. Y A

One manner of carrying out my invention, that which in practice has been found the most desirable, is illustrated in the accom pal'iyingldrawings, in which Q Figure ,1 is a side elevatlon of myassem bleld tool, showing .two pairsof jaws, one pair being in operative position. 5} '-'%viewoffsame. parts shown in Fig. 1.

Lpplicatipn filed August 18, 1905 Serial No. 274664 -various parts and operation as thereby dispensing with the necessity 'ing t Patented April 3, lens.

elevation of a set of-doublepairs of jaws, united by their respective shanks, shown in their operative, position with reference to each other, the two parts being identical in construction. Fig. 8 is a plan view of same parts'as shown in Fig. 7, and Figs. 9 and 10 are perspective views of two identical parts containing two pairs of jaws and being adapted to be operated in conjunction with each other.

Similar indices refer to and denote like -parts throughout the several views of the drawings. a

With all of the above-designated views in mind I will now take up the detail description of 'my invention and will describe the briefly and compactly as I may.

' In the drawings, the numeral 1 denotes the upper, or left-hand handle, and the figure 2 denotes thelower or right-hand handle, the two forming the one pair of-handles for va-' rious combinations of tools. The said handles are of peculiar contour, their inner ends bein somewhat flattened and circular, formhe heads a and b, respectively, and then extending back in oppositely-disposed outends parallel and lying one above the other, substantiallyas shown in Fig. 2.

Formed'on the inner face of the head a is the square fiatfaced lug c, as shown in Fig. '3, and formed transversely and centrally ward and then inward curves, with their free through the head a and the lug c is the round.

aperture d. Formed on the inner face of the head I) is the square flat-faced lug e, as shown in Fig. 4, and formed transversely and centrally through the head I) and the lug e is the square aperture In Fi -.-7 I have having t e jaws 3 and 3 havin the shanks 4 and 4 crossing each. other and terminating in the oppositely-disposed taper-nose pliers having the janvs 5 and 5 it being understood that the jaws 3 and 5 are integral, being united by-the shank 4, and also that the jaws 3 and 5 are integral, bein unitedby the shank 4". The shanks 4-an 4 are identical in construction, but are oppositely disposed with reference to each other, each having a square socket 72. and h, 'respectively,- in its outer face, whichsockets are of infinitesimally lar' .er' dimensions than are the lugs c and e,

.which are adapted to fit snugly therein. The .depth of said sockets is substantially oneshown cutting nippers 9 5 IGO half the thickness of said shanks, and continue ing on through the shanks fromsaid sockets are round apertures 12 and 7c, respectively.

It will now be apparent that the shanks for the other pairs of tools (shown in Figs. 1, 2, and 9, 10) are identical with the shanks of the tools shown in. Figs. 7, 8, and for convenience of description are similarlyindicated, the only difference in said. parts being the shape of the working parts at the ends that is to say, the jaws 6 and 6 (shown in Figs. 9 and 10) may jaws 7 and 7) may be round-nose pliers. In lke manner the jaws 8 and 8 in Figs. 1 and 2 may form wire-grips or pipe-wrenches, while their consorts (the jaws 9 and 9) may form fiat-nose pliers.

The numeral 10 denotes the transverse bolt having a permanent integral head on one end thereof, the opposite end being threaded and on which threaded portion the knurled tap 11 may be run. A portion of the shank of the bolt 10 is formed round and a portion is formed square incross-section, the round portion extending from the head being of a length substantially the same as the combined thickness of the head a and one and one-half times the thickness of one of the shanks 4 or 4', and from saidround portion the shank of the bolt 'is square, saidjsquare portion being slightly less in length than the thickness of the head b and one-half the thickness of the shank 4 or 4. By reason of the square portion of the shank of the bolt it should be noticed that the square aperture f will fit thereover when the parts are assembled, whereby as the handles are operated the handle 2 will at all times move the bolt 10 and the tap 11 therewith, and thus ell'ectually preventing the tap 11 from working loose from its contact with the handle 2.

It will now be seen that any two sets oi the tools may be brought together, as in Figs.

7 and 8, and the handles brought to the posi-' tions shown in Figs. land 2, entering the lugs c and e in the respective sockets h and h. Then by inserting the bolt 10.tlnough the apertures d, 7c, 7s, and f in the order named and running the tap 11 tightly on the threaded portion of the bolt 10 the parts will be assembled substantially as shown in Figs. 1 and 2 and whereby as the handles are moved apart or toward each other a corresponding motion will be given to the jaws when in position as in Figs. 1 and 2. It will also be noticed that by removing the knurled tap l1 and then the handle 2 the tools then in the device may be reversed-that is, causing the jaws 8 8 to exchange position with the jaws 9 9, after which the handle 2 and the ta 1 1 may be relaced, as before, or, if desire after the hanle 2 and the tap 11 are removed an entirely different set of pairs of jaws may be posiform flat-nose pliers, while their consorts (the invention and the best means for its construction to me known at this time, what I claim, and desire to secure by Letters Patent ofthe United States, is

1. A combination-tool consisting of a plurality of double pairs of jaws each two pairs of said jaws being united by a pair of shanks crossing each other with s uare sockets formed in their outer faces an round apertures extending transversely through said shanks and central of said sockets, a pair of handles having fiat heads on their inner ends with transverse apertures formed therethrough, the apertiire in one of said heads be ing round and the aperture in the other head being square, lugs formed on the inner faces of said heads of the handles which lu s are adapted to fit into said sockets in the shanks of the jaws, a bolt having a permanent head on one end the other end being threaded with its shank adapted to extend through said apertures in the shank and the heads of the handles, one portion of the shank of the bolt be ing-formed square to fit in the square aperture of one of the heads of one of the handles, and a knurled tap adapted; to be run on the threaded portion of said bolt to bind the parts together, all substantially as set forth.

2. A combination-tool embodying two pairs of jaws, a pair of shanks integrally con necting the pairs of jaws, with apertures extending transversely through the shanks in the center of-their crossing-points, and with" a square socket formed in the outer face of each shank central of said apertures, a pair of handles having flattened heads from which they extend in outward and inward oppositel -disposed curves with the rear portions of t e handles parallel with each other, a square lug extending in from the face of the head of each handle which lugs are of a size to fit said sockets in the jaw-shanks, a bolt for connecting the shanks of the jaws with the handles, a tap for retaining the bolt in pos1- tion, and means for preventing the turning of the nut by the operation of the handles, all substantially as shown and described.

In testimony whereof .I have hereunto signed my name to this specificat on, n the signed my name to this speclficatlon 1n the presence ofv two subscribing wltnesses, this the 12th day of August, .1905. I
