My invention relates to combination-tools, and particularly to an improvement upon the tool shown and described. in Letters Patent No. 530,419, granted to me December 4, 1894.

'lheobj ect in view is to construct a-tool of adjustable or interchangeable parts or members which may be arranged to adapt the sameto performvarious functions, and particularly to improve the construction of the device in the matter of the screw-drivingmember, the bit and wrench-brace, the benchvise, including the means forv its attachment to a bench, the wrench-head, and the coperating parts. l

Further objects and advantages of this invention will appear in the following description, and the novel features thereof will be particularly pointed out'in the appendedv claims.

In the drawings, Figure 1 is aview of a tool constructed in accordance with my invention arranged for use as a bit and wrench-brace. Fig. 2 is a sectional view of the same. Fig.

for use as a straight wrench and as a long screw-driver. Fig. 4 shows the short-handled screw-driver detached.v Fig. 5 shows the tool arranged for use as an S-wrench. Fig. 6 is a view of the tool arranged for use as a glass- Fig. 7 is atransverse section on the line 77 of Fig. 1 to show the latch for securing the handle against rotation. Fig. 8 is aperspective view of the device arranged for use as a bench-vise.

Similar numerals of reference indicate corresponding parts in all the figures ofthe drawings.

1 ldesignates a cross-sectionally angular shank, terminating at its outer end in a preferably integral fixed jaw 2, forming one member of the wrench-head, and fitted to' slide upon said shank is the movable or adjustable jaw 3, actuated by a feed-.screw 4, swiveled in the cross-head 5 at the inner endet' theshank. In order to adapt the-wrench for right and left handY use, the wrench-head is extended in opposite directionsrfrom the shank to form the main and auxiliary fixed jaws 2 and 2b and the main and auxiliary movable or adjustable jaws 3a and 3b. The innersurfaces or faces of themain fixed and movable jaws are channeled, as shown at 6, to receive a bit 7, as shown in dotted lines in Fig. 2.

The feed-screw 4 terminates at its inner end in a thumb-head 8, having arms or ears 8a and 8b, which are respectively constructed to form a glass-cutter and a can -opening blade. For this purpose a diamond-wheel 9 is set in a bifurcation in the ear 8a, and said ear is provided with a breaking-.notch 10 to receive the edge of the glass after the scoring thereof by the wheel. The outer edge of the ear 8b is reduced to form a blade, and the should-ers 11 of the thumb-head form rests to bear upon the top of the can or other article to be opened.V Inasmuch as these shoulders are arranged upon both sides of the plane of thecanopening blade or ear 8b, it is obvious that the can-opener is adapted for either right or left hand use.

VThe cross-head 5 is provided with perpenvdicularly-disposed screw-

studs

12 and 13, the former of which is perpendicular to the plane f of the cross-head, a'nd hence parallel with the shank'of thetool, and the latter is' formed as an extension of the cross-head, and hence is perpendicular to the shank, the end of the cross-head contiguous to the 'stud 13 being broadened to form a securing ear or rest 14,` provided with perforations 15, through which fastening screws or nails may be driven, as indicated in Fig. 8, to fasten the portion of the tool already described to a bench 16, and thus adapt it for use. as a bench-vise. The extremities of the auxiliary portions 2f and 3a of the jaws form a rest to coperate with the rest 14 to steady the apparatus when used as a vise.

The handle portion or member 17 of the IOO and bit respectively projecting beyond the contiguous extremities of the grip. The inner end of the bore of the tubular body portion of the handle is threaded to form a socket. for the reception of either of the threaded

studs

12 and 13 on the cross-head of the tool, and when the handle is attached to the ciosshead by means of the stud 13, as shown in Fig. 3, the tool is adapted for use as a straighthandled wrench or by reversal as a long-liandled screw-driver, in which case the wrenchliead forms a grip. In order to adapt this wrench-head to perform its function as a convenient grip in manipulating the long-liandled screw-driver, the exposed or upper and lower sides, respectively, of the fixed and movable jaws are rounded, as shown. The movable jaw is adapted to be adjusted outwardly to the limit of its movement when the device is to be used as a long-handled screwdriver. IVhen the tool-handle is detached, as shown in Fig. 4, it forms a sliort-handled screudriversuitable for light work or for use under conditions precludin g the employment of the long-liaiidled tool. (Illustrated in Fig. 3.) The milling of the periphery of the disk at the inner end of l[he body portion of the handle provides the proper grip by which the bit may be turned, and inasmuch as the bit is integral with the body portion of the handle it may be made of sufficient strength to resist any strain to which it may be subjected.

IVhcn the socket in the inner end of the handle is engaged with the stud 12, as shown in Fig. 5, the device is adapted for use as an S-wrench-a desirable form of the tool for certain classes of work in connection with which the ordinary or straight-handled form of wrench shown in Fig. 3 is inoperative. IVhen the handle is arranged at right angles to the shank by its engagement with the stud 12, it is desirable to secure the handle-body portion or spindle from rotation, and the means which I employ for accomplishing this object consists of a latch having a spring-aetuated bol 22, mounted iii an open-ended sheath or guide 23, preferably integral with the cross-head and parallel with the stud 12, for engaging a perforation 21 in the peripherally-milled disk at the inner end of the handle. This bolt is reduced at one end, as shown at 25, to form a shoulder 26, between which and the inner end of the guide is arranged a coiled spring 27, the parts being held in said position by the permanent attachinent of a thu mb-hold 2S to the inner extremity of the bolt, said thumb-hold serving to limit the extension of the bolt under the tension of its actuatiiig-spring.

In Figs. l and 2 I have shown the tool arranged for use as a bit and Wrench-brace, in which case the wrench-head and connected parts and the handle are arranged, as shown in Fig. 5,with the handle in engagement with the stud 12 or perpendicular to the shank, and applied to the outer end of the handle is a brace-arm 2f), provided with a ciossscc tionally angular terminal socket 30, which is adapted to fit upon and forni a sheath for the screw-driver bit at the outer end of the handle. Thus the screw-driver bit performs, in addition to its usual function, that of a stud for the attachment of the brace-arm, and by tapering the screw-driver bit the brace-arm may be driven to place thereon to form a su ffi ciently firm attachment of the parts.

From the above desci'iption it will be seen that the screw-driver bit is permanently attached to the body portion of the handle and is adapted to perform its function as a screwdriver when exposed by the removal of the brace-arm and either detached from the shank or attached parallel therewith, as shown, respeetively, in Figs. 4- aiid IVhen the handle is detached from the shank, the latter may be attached to a bench for use as avise or maybe reversed to perform its function as a glass-cutter or can-opener. The rest,whicli is formed upon the extremity of the eiosshead and parallel with the shank to bear upon the bench, is located at the saine distance from the shank as the extremity of that portion of the wrench-head which is upon the same side of the shank, or that portion of the wrench-head formed by the auxiliary fixed and movable jaws. Thus when the device is arranged for use as a bench-vise the face of the rest and the extremity of the short end of the Wrench-head bear upon the surface of the bench, the additional bearing formed by the short arm of the wrench-liead serving to steady the device and relieve the securing means of strain.

The advantage of the manner of mounting the latch resides in the fact that the spring and contiguous portion of the sliding bolt are wholly concealed Within the sheath and are thereby protected from moisture to prevent accumulations of dust and rust from rendering the latch inoperative.

Some of the uses of the tool embodying my invention have been above described; but it is obvious that its parts or members are capable of numerous relative arrangements and are adapted to perform functions which it is unnecessary to explain herein in detail; and it will be understood, furthermore, that various chan ges in the form, proportion, and the minor details of construction may be resorted to without departing fi'oin the spirit orsacrificin g any of the advantages of my invention.

Having described my invention, what I claim is- 1. In a tool of the class described, the combination of a shank carrying fixed and adj ustable jaws, a detachable handle having a core or body portion upon which is mounted a revoluble grip, said core or body portion terminating at one end, beyond the contiguous extremity of the revoluble grip, in a handhold, and terminating at the other end in a cross sectionally angular screw-driver bit which projects beyond the contiguous ex- IOO IIO
