JOHN EMIL J OHNSOI V, OF JAMESTOWN, NEW YORK, ASSIGIiTOR TO CRESCENT TOOL COMPANY, OF JAMESTOWN, NEW YORK, A'CORPORATION.

. COMBINATION-TOOL.

. To all whom it may concern:

Be it known that I, JOHN EMIL JOHNSON, a citizen of the United States, residing at the city of Jamestown, in the county of Chautauqua and State of New York, have invented certain new and useful Improvements in Combination-Tools, of which the following, taken in connection with the accompanying drawings, is a specificatlon.

The invention relates to a combination tool and the object of the improvement is to provide a manually operated screw-driver of great strength and power in which the handle may be turned in .a crosswise position to give greater leverage upon the screwdriver bit, or the handle may be used in line with said bit like the common form of screwdrivers, and automatically locked in either of these two said positions; and second, to provide a socket in one end when the screwdriver bit is turned at right angles to the,

handle for'the reception of the shanks of bits, ratchets, etc., for use in confined spaces in which the full length screw-driver could not consists in the novel' features and combinations hereinafter set forth and claimed.

In the drawings, Figure 1 is an elevation of the tool with the handle turned crosswise of the end of the tool; and Fi 2 is an elevation of the tool with the handle in line with the same. Fig. 3 is a detail of the upper end of the screw-driver bit removed from the handle showing the conformation of the same. Fig. 4 is an, elevation of the tool with the handle turned in the cromwise position and end of the socket with the slot inone side and the locking notch in the other, which assist in holding the screw-driver bit when the handle is turned in line with the same. Fig. 5 is a lengthwise sectional view of the handle with the end of the screw-driver bit attached therein and turned at right angles thereto showing the construction and arrangement .of the parts when assembled and a socket tool therein. Fig. 6 is a per-' spective view of the pin against which the upper end of the screw-driver bit operates when held in position by the coil spring. Fig. 7 is a sectional view of the stem of one of the socket tools showing the key on one side-and the spring catch on the other side of the same.

Like numerals of reference refer to corresponding parts in the several views.

The numeral 10 designates the handle, and

the numeral which is attached to fol owing manner:

The handle 10 is preferably made of steel and knurled on its outer surface in order to give a strong grip on the same. A tubular socket or bore 12 is provided in one end which extends nearly the length of the handle 10. An open ended slot 13 is provided in one side of the handle 10 extending into the socket 12 and a little over half the length of the handle. 10 to receive therein the flat upper end14 of the screw-driver bit 11, being attached to the handle 10 by'means of a screw or'pint-le 15 extending through said handle and a hole l'6 i'nthe upperend 14 the handle 10 in the the handle 10 to provide, an equal leverage I o n each side of the end 14 of the bit 11. socket tools such as wrenches, screw-driver f formed with its fits against the wall of the inner end of the when the bit or blade ll is turned slot 13 at right angles to the handle 10, thereby aiding in the firm holding of said bit.

A plunger 21 having ahead 22 Which slidably fits within the socket 12 is provided said socket to bear against the sides 19 and 20 of the upper end 14' of the bit 11, being given a resilient pressure. thereagainst by a coil spring 23 which bears against the head 22 of the plunger 21 at one end and against the inner end of the socket 12 at the other. i The head 22 of the plunger 21 is preferably hardened in order to endure the wearing pressure of the blade 11 as it is turned back and forth against the same. If the plunger '21 were cup-shaped and the spring 23 were received within the cup it would not depart from my,

11 the screw-driver bit or blade hammer and the handle 10 I oeedingly convenient position by means of the plunger 21 and stifispring 23 makes a very serviceable ham-- mer of the head 24.

The flat portion 14 may be formed with the shoulders 25 for strength as well as beauty of design or said fiat portion may have straight sides where greater stiffness is desired or the bit 11. The shank of the bit 11 is preferably made round for convenience in manipulation of the tool while turning the same.

The socket or, bore forms a convenient opening when the bit 11 is turned at right angles to the handle for the reception of a socket tool 26. The socket tool 26 is provided with a shank 27 having a projecting lengthwise feather key 28 on one side and the spring catch 29 on theother to enter a socket 30 on the inner wallv of the socket 12 opposite the slot 13. The key 28 fits within the lengthwise slot 13 and theshank or stem 27 is proportioned as to length to fit within the socket 12 so that when the inner end strikes against the side of the v enter the socket 30, thereby preventing the tool from falling out of the socket and holding it firmly. The tool may consist of a ratchet 31 other tools such as a short screw-driver 32, as shown, or a wrench or boring tool, and when so inserted the handle 10 may be turned by means of the bit 11 thereby operating the ratchet 31 and turning the screwdriver 32 in a' comparatively small space.

The socket or bore 12 also forms a convenient opening for inserting a bar or the handle of another tool for obtaining greater upon the handle .10 and screwleverage 11 in starting rusted or heavy madriver bit I chine screws.

I claim as new a 1.,A tool comprising a handle formed with a socket extending through one end thereof and provided with a slot extending partially the length of the socket from the opened end thereof whereby the inner end portion of the slot forms a rigid abutment immovably secured .to the socket, .a tool shank pivoted in the socket of the handle end of the slot to extend either through the latter or through the socket and when extending through the slot to seat against said abutment, and means automatically operating abutting the shank atall times to automatically release and old the shank and when the latter extends 1; ii the slot holding said shank against desired. The

12 of the handle 10 letter end and bit 11 the spring catch 29 will to receive therein the shanks of ant em 2. A tool comprising a tubular handle closed at one end and opened at the opposite and and formed with a relatively narrow slot opening throu h the opened end thereof,- a thin flat tool pivoted in the d end wall of the slot.

handle to lie disposed either through the slot or through the opened end of the handle, a spring-pressed plunger arranged in the handle between the closed end thereof and the tool shank to exert pressure against the latter and automatically, shifted by the shifting of the tool shank, means insertible 1n the opened end of the handle, when thetool shank extends through the handle slot, for. constituting an auxiliary handle and abutting the tool shank and cotiperating with the plunger in holding the shank so disposed, and means to positively lock said means agamst movement.

3. A tool comprising a tubular handle closed at one end and opened at the opposite end whereby a device may be inserted in the formed with a relatively narrow slot opening through the opened en. thereof, a thin fiat tool shank pivoted in the handle to lie disposed either through the slot or through the opened end of the handle, means yieldably disposed in the closed end portion of the handle and engaging the tool shank on one side when the latter extends through the handle slot and on the inner end when said shank extends through the opened end of the handle, and a device said device constituting an auxiliary handle and abutting the opposite side of the tool shank for positively holding the same and having a spring latch handle.

4. A tool comprising a tubular handle closed at one end and opened at the opposite end whereby a device may be inserted in the latter end and formed with a relatively narrow slot opening through the opened en thereof, a thin flat tool shank pivoted in the handle to lie disposed either through the slot or through the opened end of the handle, and a tool device entirely plugging and removably fixed in the opened end of the handle, when the tool shank extends through the handle slot, for abutting the. tool shank to hold the latter immovable and for constituting an auxiliary handle.

In testimony whereof I have afiixed my signature in the presence of two witnesses.
