UNITED STATES FRANKLIN JOSEPH HEMMERLY, OF EAST RENOVO, PENNSYLVANIA.

COMBINATION TOOL.

Application filed November To all whom it may concern:

Be it known that I, FRANKLIN JVHEM- MERLY, a citizen of the United States, residing at East Renovo, in the county of Clinton and State of Pennsylvania, have invented a new and useful Improvement in Combination Tools, of which the followingis a specification. a I

This invention relates to combination tools and, while useful in many places, is designed especially for use in connection with automobiles.

The object is to provide a tool in the form of a screwdriver, having its blade preferably magnetized for the purpose of attracting and holding screws or other parts, and also to equip the handle of the driver with additional turning means for the same to make the operation easier on the hands, said means acting to strengthen the union between the blade of the driver and the handle of the same, and being capable of removal therefrom to be used independently in the dual capacity of a cotter-pin remover and a scraper in removing grease, rust, and other accumulations from bushings, bearings, or other parts of the machine.

A full andcomplete understanding of the invention may be obtained from a consideration of the following detailed description taken in connection with the accompanying drawing forming a part of this specification, it being understood that while the drawing shows a practical form of the invention, the latter is not to be confined to strict conformity therewith, but may be changed or modilied, .so long as such changes or modifications mark no material departure from the salient features of the invention, as specifically pointed out in the appended claims.

In the drawing, in which similar reference characters designate corresponding parts throughout the several figures:

Figure 1 is a side elevation of the improved combination tool,

Fig. 2 is a longitudinal section through the handle of the tool and the adjacent portion of the blade thereof,

Fig. 3 shows one member of the device in use as a cotter-pin remover, and

Fig. 4 illustrates the manner of using the device as a scraper.

The screw-driver blade 1 may be formed of suitable metal having the usual round shank 2 of any desired length and diameter, and

1, 1921. semi No. 512,146.

the said shank 2 is provided adjacent to its inner end with a transverse holed. A handle 4, preferably formed of suitable wood and reduced at 1ts inner end for the reception of a metallic ferrule 5, is adapted to be fitted onto the inner end of the shank and to be held thereon in the usual manner said shank extending nei'irly to the end of the handle. In alinement with the hole 3 of the shank, the wooden handle is also provided with a passageway registering therewith, and through these alined openings is passed a transversely disposed bar 6 formed of hardened tool steel, round in cross-section, and of a diameter to snugly fit the said openings and to be retained therein by frictional engagement.

The bar 6, which constitutes in its entirety a combined scraping tool and cotter-pin remover, extends substantiallv equal distances outwardly from opposite sides of the handle of the screwdriver, when the same is nositioned through the said openings, and at one end the said bar is beveled oii", as at 7, such beveling being preferably struckon a curve of a relatively large radius and providing a knife-edge end 8 rounding, as viewed in plan, and, this end constitutes a scraper for removing accumulations from bearings and other parts, as when repairing an automobile or other machine.

That portion of said bar 6 extending from the other side of the handle has an upward, arcuate bend 9 terminating in an outwardly and downwardly directed spur 10, extending at an inclination with relation to the body portion of the bar and having fiat sides terminating in a point 11.

The screwdriver blade preferably magnetized for the purpose of retrieving lost screws or other small parts difiicult to recover otherwise, and the said blade offers simple means for testing the spark plugs of an automobile by simply laying the blade on the spark plug being tested, the shank of the same being caused to touch the cylinder or other metallic part when, if the plug is alive and active, the fact will be shown by a spark, the wooden handle serving to protect the hand from shock.

The foregoing use of the device may, of course, be accomplished with the bar 6 removed from its position in the alined passageways, and the driver may also be used in this condition for moving screws that may be easily turned. However, it is advisable to keep the bar 6 in its position in the screwdriver to prevent mislaying or losing the same, and when the said bar is in position, it will be seen that, by reason of the same passing through the shank of the driver as well as the handle, that powerful pressure and increased turning power may be brought to bear to turn a stubborn screw, the handle easily fitting between the middle fingers of the operator, and the two pairs of opposite fingers encircling the proectlng parts of the bar 6 in a natural and comfortable manner. I

As illustrated in Fig. 3, the shank of the bar 6 may be readily grasped in the hand to introduce the point 11 into a cotter-pin A, with the arcuate bend 9 inverted as shown when, by simply bearing downwardly by hand, the tool will be caused to rock thereon and the cotter-pin be removed from its seat, as will be clearly understood. 1 prefer, however, in many cases to utilize the screwdriver as a lever in removing cotterpins, in which case the two elements will remain assembled in the position shown in Fig. 1, and the cotter-pin may be engaged by the point 11, the rounded 0nd of the handle of the screwdriver acting as a fulcrum in drawing the pin.

By reversing the bar 6, with the arcuate bend 9 directed upwardly to cause the same to comfortably fit the palm of the hand of the operator, the cutting edge formed by the bevel 7 is located beneath and in position to remove accumulations from any part of a surface, as clearly shown in Fig. t of the drawing.

From the foregoing it will be seen that a simple and cheaply manufactured -coinbination tool has been provided, which may be effectively used for various purposes in the repair and up-keep of an automobile or other machines, and that the component parts, though separable, may be kept together for instant use at all times and stowed away to occupy little space.

handle to form a cross-head for the handle,

2. The combination with a tool having a metallic shank, and a handle into which the shank extends longitudinally, of a bar extending transversely through the shank and handle near the end thereof and frictionally held therein to lock the shank in the handle,

the bar at one side of the handle having an arcuate bend terminating in a point andcooperating with the end of the handle to form a cotter-pin puller.

3. A combination tool having a metallic shank, a handle having a-longitudinal bore into which the shank extends longitudinally, said shank and handle having transverse registering holes therethrough, a bar extending transversely through the holes and frictionally held therein to lock the handle to the shank and extended beyond the sides of the handle to form a cross-head.

4. A combination tool having a metallic shank, a. handle into which the shank extends longitudinally, said shank and handle having transverse registering holes therethrough, a bar extending transversely through the holes and frictionally held therein to lock the handle to the shank and extended beyond the sides of the handle to form a cross-head, the end of the handle beyond the shank being rounded and consti tuting a fulcrum whereby the cross-head may be used as a lever.

In testimony, that I claim the foregoing as my own, I have hereto afiixed my signature.

FRANKLIN JOSEPH HEMMERLY.
