SPECIFICATION formingpart of Letters Patent No. 423,513, dated March 18, 1890.

' Application filed April 29, 1889. Serial No. 309,108. I (No model.)

' f To all whom it may concern-.-

Be it known that we, ALEXANDER CLARKE and J QHN F. CLARKE, subjects of the Queen exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

Our invention has for its object to provide a novel combination-tool, to be used in any ordinary bit-stock, the combined tool having a variety of useful tools, such as are more ordinarily in demand, in connection therewith,

while, also, any other desired tool of the same general class can be readily engaged therewith, as may be required.

3 vertical section through the jaws, showing one of the jaws in elevation, with catch in position. Fig. 3 is a similar section showing the other jaw and certain of the various tools in engagement therewith, with catch removed. Fig. 4 is a top plan. Fig. 5 is a separate view of the spring, and Fig. 6 shows a detail view of the shank of a separable tool to be engaged in the jaws of the combined tool.

For many purposes-as, for instance, in carriage-making, for domestic uses, for farmers, and the like-where a kit of tools is not desired or where tools are needed in most convenient form, a combination-tool of the description herein set forth and illustrated will be found to facilitate labor, economize time, and embody in itself a cheap device capable of a great variety of services.

WVe carry out our invention as follows:

A and A represent jaws constituting the body of our improved tool. As shown, said body may consist of two jaws properly united in any desired manner. In the drawings they are shown connected by a rivet 00. These jaws may be cast, and may be, preferably, tapering toward the base, where they are engaged by a ferrule B, preferably milled on its exterior. Sleeved through said ferrule is a shank O, constructed at one extremity to be engaged in any ordinary bit-stock. At the opp'osite end the shank has a screw-threaded engagement with the jaws.

We do not limit ourselves exclusively to the definite construction of jaws illustrated herewith, nor to any definite manner of engaging the shank O therewith. When the shank is engaged in'a bit-stock, one hand may grasp the ferrule B to steady the tool and keep it in place. The jaws are recessed at their upper ends, as shown at a a a a to receive a series of tools, which may be pivotally engaged or otherwise jointedly united with the jaws. -'lhus, for example, D is a screw-driver; D, a gimlet; D and D diiferent styles of reamers.

We do not limit ourselves to any specific kind of tools to be united with the-jaws nor to anyparticular number of them. WVe have shown four in the accompanying drawings,

vmay be turned down alongside thejaws, as

shown, out of the way, in which position they may be held securely in any desired manneras, for instance, by afriction-post cZ*-or the frictional contact of the shoulders cl of the .tools in the recesses a a a a respectively,

may serve to hold the tools in place alongside. the jaws. Any desired means for so holding the tools in place when not in use may be employed. To effect the-entrance of the pivots d, the jaws may be hollowed out adjacent thereto, as shown at a. We do not limit ourselves to the pivots for uniting the individual tools in the jaws.

Where it is desirable to facilitate the removal of a given tool from the jaws, a spring stud (1 might be employed. As shown, the end of the stud is secured to a short flat the operator, by pressing upon which the tool them in a firm position.

spring, the latter held normally in close prox-- imity to the surface of the jaw by a rivet or bolt, which secures it thereto, the end to which the stud is attached having a yielding movement away from the surface to release the stud from the tool. As so hung or engaged in the jaws it is evident that any given tool of the series may be erected in position for use, as shown, for example, in. Fig. 1. Being provided with the shoulder d, through which the tools are pivoted to the jaws at one side .of the center of the united jaws, it is evident that the tools when erected for use will be thrown to the center of the jaws.

To hold the tools in an erect position, we

provide a spring-latch E, having a jointed or other proper union with the jaws, constructed to engage the shoulders of the tools and hold Thus the latch may be constructed with a notched head 6 and an arm e, extended through one of the jaws, within easy reach of the thumb or finger of may be released and turned out of the way, a spring (2 restoring the latch to its normal position. The individual tools may be constructed with shoulders d, notched as at d, to

engage the latch, a single latch serving to hold all the tools successively in an erect position. Should it be desired to use a separable tool with the jaws, a tool F, Fig. 6, for any purpose, its shank may be formed to enter the open end of the jaws, as shown in Fig. 4, for instance, and engage the spring-latch E.

What we claim is' 1. A combination-tool having a body portion provided with a central opening in one end,and with radial slots or openings extending from the central opening through to the outside of the tool, tools hinged in the radial slots, and a central catch adapted to automatically engage any one of the. tools when.- for use, subswung into extended position stantially as set forth.

2. A combination-tool having abody portion provided with openings in its end, tools hinged in the openings, a ferrule loosely se cured on the shank end of the body portion for holding the tool, and a catch adapted to engage the tools and lock them in working adjustment, substantially as set forth.

3. A combination-tool. having a body portion'provided with a central opening in one end, and with slots or openings extending radially from the central opening through to the outside of the body, tools hinged in the said slots, the hinged ends of the tools forming, when the tools are folded, the walls of an opening to receive a separable tool, and a catch for engaging the tools, substantially as set forth.

4. A combination-tool comprising a body" portion formed of united jaws or sections, and provided with a central opening and slots radiating from one end thereof, a shank engaged with the body, and aseries'of tools having a jointed engagement with said body, substantially as set forth.

In testimony whereof we sign this specification in the presence of two witnesses.
