JOHN JENKS, OF SAN DIEGO, CALIFORNIA.
1'0 all whom it may concern:
Be it known that 1, JOHN JnNKs, a citizen of the United States of America, residing at San Diego, in the county of San Diego and State of California, have invented certain new and useful Improvements in Combination-Tools, of which the following is a specification.
This invention relates to combination tools and more particularly to a combination screw-driver and brad-awl, the object of the invention being to provide a device of this character consisting of two parts, one of which carries a brad awl point and the other of which is provided with a screwdriver point, the two parts being capable of a limited longitudinal movement with relation to each other, and being so constructed that when the brad-awl portion of the device is swung into alinement wit-h the screw driver portion of the device and the bradawl point is then moved toward the screwdriver end, the parts are automatically locked into engagement with each other and the device may then be used as a screwdriver. By moving the brad-awl point away from the screw-driver end, the bradawl point may be disengaged from the screwdriver end and swung at right angles thereto, at which time this brad-awl point may be used in the ordinary manner independently of the screw-driver end. This is a particu larly advantageous arrangement for starting screws, the awl serving to make an incision in the wood in which the screw may be started and afterward driven home in the usual manner by the screw-driver end.
Further objects and advantages of the invention will be set forth in the detailed de scription which now follows.
In the accompanying drawin Figure l is a side elevation of a tool constructed in accordance with the invention, with the bradawl disengaged from the screw-driver end, Fig. 2 is a longitudinal vertical section through Fig. 3, Fig. 3 is aplan view, and, Fig. 4 is a transverse section upon line 4-4 of Fig. 1.
Like numerals designate corresponding parts in all of the figures of the drawing.
Referring to the drawing, the numeral 5 designates a tubular shank having a periph eral groove 6 formed therein and having a handle extension 7. This extension 7 may itself form the handle or may carry a separate wooden handle (not shown). The
Specification of Letters Patent.

Serial No. 555,579.
shank 5 carries a brad'awl point 8 and between this brad-awl point and the shank is formed a portion 9 angular in cross section, see Fig. 4. Disposed for limited longitudinal movement upon the shank 5 is a sleeve 10. This sleeve has an overhanging ledge 11 which spans the shank 5. The sleeve carries a screw-driver end 12 and is provided with a longitudinal recess 18 for the reception of the brad-awl point. The upper portion of the sleeve 10 is cut away at 14; as shown and a slot 15 is formed in the wall of the sleeve. That portion of the bore of the sleeve adjacent the slot 15 is angular in cross section as indicated at 16 in Fig. 4. Spring clips 17 carried by the sleeve 10 are adapted to snap into the peripheral recess 6 when the parts are in the position illustrated in Figs. 2 and 3, to thereby lock the parts against longitudinal movement with relation to each other.
When it is desired to use the brad-awl, the shank 5 is moved to the right in Fig. 2 with relation to the sleeve 10. This withdraws the brad-awl point 8 from the recess 13 and the brad-awl portion of the device may then be swung to a position substantially at right angles to the screw-driver end as illustrated in Fig. 1, the brad-awl point at this time passing through the slot 15. hen it is desired to use the tool as a screw-driver, the brad-awl portion of the tool is swung into longitudinal alinement with the screwdriver portion thereof, and is then moved longitudinally to the position illustrated in Figs. 2 and 8, at which time the spring clips 17 snap into the peripheral groove 6 and the angular portion 9 moves into engagement with the angular opening 16 of the screw-driver end whereby turning of the shank 5 results in turning the screwdriver portion of the tool.
From the foregoing description, it will be seen that simple and efficient means are herein provided for accomplishing the objects of the invention, but while the elements shown and described are well adapted to serve the purposes for which they are intended, it is to be understood that the invention is not limited to the precise construction set forth, but includes within its purview such changes'as may be made within the scope of the appended claims.
Having described my invention, what I claim is:
1. In a device of the character described,
the combination with a serewdriver end, comprlsing a sleeve having an opening formed in one side thereof, a handle portion, a tool carried by said handle portion and adapted to fit within said sleeve, said tool and said sleeve being capable of a limited longitudinal movement with relation to each other, and means for locking said tool and sleeve against longitudinal movement with relation to each other, said tool comprising an angular portion adapted to fit Within an angular portion of the bore of said sleeve, to prevent said tool from turning with relation to said sleeve.
2. In a device of the character described, the combination with a screw-driver end, comprising a sleeve having an opening formed in one side thereof, a handle portion, a tool carried b said handle portion and adapted to fit wlthin said sleeve, said tool and said sleeve being capable of alimited longitudinal movement with relation to each other, and means for locking said tool and sleeve against longitudinal movement With relation to each other, said tool comprising an angular portion adapted to fit within an angular portion of the bore of engage in an angular portion of the bore of said sleeve, an awl point carried by said shank and adapted to enter said recess, a handle portion carried by said shank, a recess formed in said shank, spring clips carried by the sleeve and adapted to engage in said recess, and a screw-driver end carried by said sleeve.
In testimony whereof I affix my signature in presence of two Witnesses.
