To all whom it may concern:

Be it known that LPnmoE E. SHORTT, a citizen of the United States, residing at Floyd, in the county of Floyd and State of Virginia, have invented a new and useful Combination-Tool, of which the following is a specification.

This invention relates to compound tools of the auger type and its object it to provide a tool of this character made up of adjustably c ".inected members designed to be adjusted to various positions with respect to one another, and to be assembled in different ways to enable the device to be used for various purposes, a vise, a wrench, a wire-cutter, etc.

I Another object is to provide an auger having a detachable handle section designed to be secured in position in a simple and eflicient manner and which can be readily discarded, when the tool is to be used forother u oses.

l'ifith these and other objects in view the inventwn-cqnslsts of certain novel details ofconstruction and combinations of parts hereinafter more fully described and pointed out in the claims.

in the accompanying drawings the preferred form of the invention has been shown.

In said drawings:-Figure 1 is a side elevation of the tool with parts so assembled as to enable the same to be used as an auger. Fig. 2 is a view partly in side elevation and partly in section showing the parts of the tool arranged for use as a wrench, one, of the positions of dotted lines. Fig. 3 is a side elevation of the tool in'position for use as a vise, the jaws the vise being shown in another positi'ofiby means of dotted 4 is a perspective view of the threaded stem used for athandle to the tool, said stem, when detached, as shown in said figure, being designed to be used as a screw-driver. Figs. 5 and bi are elevations of the inner or ad oining faces of the two heads of the tool. Fig. 7 is an end view of the grip of the au er.

tool, said shank bein 6 preferably such, for example, as an auger,-

the handle being shown; by

lan viewof the coup 'ng Referring tothe ligures by characters of reference, 1 designates the main shank of the rovided at one end with a head 2 prefera y integral therewith and having integral jaws 3 and 4 formed by the end portions thereof. The working face of the aw 4 is concave as indicated at 5 and provided with transversely extending teeth, while the working face of the jaw 25 is formed with a series of transversely extending teeth arranged diagonally as indizated in Fig. 6. A head 7 is slidably mounted on the shank and the ends of this head form jaws 8 and 9 designed to cooperate with the jaws 3 and 4. Jaw 9 has a series of transvengelv extending teeth 10 u on its working face, while the jaw 8 which islbca'ted directly opposite the jaw 3, is provided witlia series of dia onally extending teeth 11. ()p ositely isposed recess-s 12 are formed witliin the working faces of t ie two jaws 3 and 8 and. extending from these recesses, which are preferably substantially semi-spherical, are grooves 13 triangular in cross section and gradually increasing in width and depth toward the free ends of the jaws 3 and 8. Smaller grooves 14 connect the broad ends of the grooves 13 with the ends of the jaws 3 and 8, as clearly indicated in Figs. 5 and 6. When the two jaws 3 and 8 are brought to- 8b gether the recesses 12 and the grooves 13 and 14 register to form a socket, and this socket is designed to receive the head of a bit, not shown. The jaws 4 and 9 are especially designed to engage pipes and other round objects, and, by reason of the peculiar contours of the working faces of these jaws, they will firmly grip thereon.

"Arranged upon that end of shank 1 farthest removed from the head 2 is a cross- 9.5 head, 15, one end of which f rms an arm 16 in which is swiveled the stem 17. One end of this stem is provided with a milled head 18 whereby said stein can be readilj turned by hand. 'lhe greater portion of the stem is screw-threaded as indicated at 19, and extends intoand engages the threaded opening 20 extending through the jaw S. albeiously' by rotating this stem 1? the threaded portion thereof will operate to feed the head .7 toward or from the head 2.

i The ofiheljelld of the cross-head 15 is en larg das indicated at 21 and provided with a transverse slot 22, which divides said end portionslintotwosimilarears. Central open- 3 are formed within these ears and are d to receive a pivot pin 24 having a hat taco extending longitudinallythereon and terminating at. a shoulder 26. This pin is siidahl) mounted within the openings 23 ings 2 dcsignc the jaw has been obtained the head of a bit, not shown, may be placed between the two 'aws 3 and 8, so that when jaw 8 is ad'usted ack toward the jaw 3 the head of t e bit will become seated Within the angular rdand is limited in its movement by the head cesses 13 and the groove 14.

ot the pin and by the shoulder 26, there hang a stop pin 2% projecting into one oi the ears and contacting with said flattened face L53. l obviously not only limit 'i his pin wit 7 the longitudinal movement of the pin .24, but trom rotating within also prevent said pin the enlargement 2-1. The enlargement 21 has transversely extending shoulders 29 and 3t) arranged thereon at.about one hundred and eighty degrees apart and those portions oi' the enlargement which are located between theshouldcrs are rounded as shown at 31.

V-shaped lugs 32 are arranged upon these rounded portions and at points equi-distant from the shoulders 29 and 30. These rounded portions between the shoulders and the projections 82 constitute seats for a collar 83 formed at one end of a sleeve 34. The end lace of said collar is so shaped as to fit snugly upon the rounded portion of the cross-head and against the shoulders and projections as clearly indicated in Figs. 1 and 2. Ahead 35 is formed at the end of sleeve 34 farthest removed from collar 33, and revolubly mounted upon the sleeve between said head 35 an the collar 33 is a grip 36. A recess 37 i'ormcd in the one face of the head 35 and is for the purpose hereinafter set forth.

Pivotally mounted upon the pin and ithin the slot 22 is a ring having a cutting nose 39 extending from the periphery thereof and desi nod to cooperate with the shoulder 31) for t e purpose of cutting wire. A screw-threaded stem 40 extends from this ring 38 and close to the nose 39, said stein having its free end beveled as at 41 so as to constitute a screw-driver. A nut 42 is mounted upon the threaded stem and is for the purpose hereinafter set forth.

The stem 40 is designed. to extend through a tubular head 43 formed at one end of a crank-arm 44 on which a knob such as is or dinarily used in connection with angers is mounted, as indicated at 45. 1 The nut -12 is desi 'ned to'turn against the head 43 so as to firm y bind it against the head 35, and, in order that the crankrm A l may be held against independent movement relative to the sleeve 34 and the head 35, a lug 46 is arranged upon the head 43 and is designed to be seated withinrecess 37 as clearly indiouted in Fig. 1.

As heretofore stated the tool herein described is primarily designed for use as an auger. hen the parts are assembled as indicated in Big. 1 the jaw away from the jaw 3 by means of the teed screw 19 and utter a suil'icient movement of l l l l t j l l t l l l i t t t 8 can be adjusted.

When the parts have thus been assembled the knob 15 can be placed a ainst the body and the operator by taking told of grip 36 can revolve the device so as to properly rotate the hit held thereby. By shifting the position 01 the crank-arm 44 so that it will extend in the opposite direction from the grip 36, or, in other Words, so that the crankarm 14 and the shank 1 will extend in opposite directions, the tool constitutes an efiicient device for cutting and cleaning horses boots, because a suitable sharp blade can be clamped between the jaws 3 and 8 and the knob held against the body While said blade is being manipulated. By removim the nut 42 the crank-arm 44 can he slid off oi the threaded stem 40, and-said nut can then be replaced upon the stem and screwed against the head 35 of sleeve 34.

With the parts thus assembled the tool can be used as a wrench and, if desired, the grip portion 36 can be placed in a line parallel with the shank as shown in full lines in Fig. 2 simply by sliding the grip 36 longitudinally on the stem 40 until said grip becomes disengaged from the. shoulders and projections on the enlargement 21. The handle or grip can then be swung either into the position shown in full lines or into the position shown'in loo dotted lines in Fig. 2, and after this position has been obtained the grip can be shifted against the enlargement 21 so that its collar 33 will be seated between the projections 32 and either the shoulder 29 or the shoulder 30. By screwing the nut 4'2 on to the stem 40 the grip will thus be securely held against dislacement. j

Obviously by rotating the screw 19 the jaws 8 and 9 can be adjusted tow the jaws 3 and l, and by reason of the peculiar construction of these jaws, they can be used either to grip nuts, or pipesand similar round objects.

One of the important l'eatures of the pres- 11.5

he Fact that it can be readily This has been clearly indi- The table "A" on which the vise is to be used is provided with an opening a designed to receive the stem 4U. the stem has been placed in this position the grip 36 is replaced upon the stem with collar 33 in contact with the bottom surface oi the table-top. The nut. .42 is then screwed on to the stem 40 so as to bind the c grip against the lower fare ol the table "A." As shown. in full lines in Fig. 3 the vise can be placed with the jaws 4 and t) in contact with the table and with shank 1. extending at right angles to the stem 40.

cut invention is it used as a vise. cated in Fig. B.

After ollar 33 of the \l'hen in thisposition the shoulder 30 and the projections 32 will bear upon the top of the table. The eflicienev of the jaws 3 and 8 in this connection is greatlv increased by the provision of a transverse groove 47 in the working face of the jaw 3 so that small objects such as nails and the like can be securely held between the jaws I and 8. This is especially desirable where it is designed to bend or upset nails, or to form staples, etc. it will also be noted that the working faces oi the two jaws 3 and 8 are provided with straight transvcrselv extending teeth 48 which are located at the inner ends of said working faces. These teeth are found to be vcr desirable in hold ing some forms oi work.

Under some conditions it is desirable to have the jaws of the vise adjustable vertically and beyond the edge of the table. \Vith the present invention this is possible by loosening the vise and swinging the cross-head so that it will assume a position at right angles to the stem 40. Such an arrangement has been indicated by dotted lines in Fig. 3, and when the parts are thus positioned the projm-timm 32 and the shoulder 29 bear upon the table.

Among other uses to which this tool may be put are those of a wire-cutter and a screwdriver. To cut wire the collar 33 is adjusted own from the enlargement-21 so as to expose the nose 39. The wire to be cut is then plea-ed. against the curved portion of the enlargement '21 and between the extensions 32 and the shoulder 30. By swinging the stem 40 upon its pivot-pin 24 the nose 39 will fort-e the wire against the shoulder and cut it. It is of course to be understood that this shoulder 30 is intersected by the slot '22 so as to permit the nose 39 to 11love past it.

To use the tool as a screw-driver the pin 24 is slid outwardly as far as it can be moved. and this movement will be sufficient to re-- lease the ring 38. The stem 40 can thus be detached from the rest of the tool, and, by removing the nut 42, the gri) 36 and the parts combined therewith can be withdrawn from the stem to. By replacing the nut 42 on the stem and close to the ring 38 the devie-e will have the appearance indicated in Fig. 4, and can be conveniently used as a screw-driver. I

It will be seen that this device is verycompact and efiicient and will be found very desirable because of the number of different uses to which it may be put. Considering its usefulness and the numerous functions as cribed to it, the tool is formed of com )arativclr few parts, and these parts will not easily get out of order.

Obviously various changes may be made a in the sizes and proportions of the parts with i out departing from the spirit or sacrificing the advantages of the invention.

As shown in Fig. 11 a ratchet bit socket, i

such as indicated at 49, may, if desired, be secured between the jaws 3-and 8.
