RAToHET-vvlV-lE151.` WRENCH'.

SPECIFICATION forming part-f Letters Patent No. 603,377, dated May s, 189s. Application filed November 12, 1897. Serial No. 658,336. (No model.) v

To all whom it may concern:

Be it known that I, JOHN H. FITCH, a citizen of the United States, residing at Wesley, in the county of Mason and State of Michigan, have invented certain new and useful Improvements in a Combined Drill and Wrench; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a combined drill and wrench; and the object of the invention is to provide` an interchangeable' device of this character which shall be simple of construction, durable in use, and comparatively ineX- pensive of production.

With this obj ect in View the invention consists of certain features of construction and combination of parts which will be hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a perspective view ofthe device when used as a wrench. Fig. 2 is a similar view of the interchangeable'bushing. Fig. 3 is a longitudinal sectional view of the wrench with the bushing in place. Fig. 4. is a perspectiveview of the device, the bushing being removed and la drill-hold er,with its feed-screw, substituted,

showing the device when used as a drill. Fig. 5 is a perspectivev view with the drill-holder and feed-screw removed from the head of the tool, vand Fig. 6 is a transverse sectional view showing in full lines the dog held tilted in one direction by the spring and in dotted lines the dog held tilted in the opposite position.

In said drawings, 1 denotes the handle of the Wrench, which, as shown, is preferably provided with two parts a and b, each formed with enlarged outer ends having bearings 2. Journaled in these bearings is a head 3, having upon its outer periphery a series of ratchetteeth 4.. This head is provided with alined and communicating nut-sockets 5 and 6 of different areas, so as to adapt them to nuts of different sizes.

7 denotes a bushing which is provided with a groove 8, in' whichY is secured one end of a double spring 9. When the bushing is inserted into the head, the spring will force itself up into a recess cin the head and hold the bushing in place against accidental dis-` engagement. This bushing has nut-sockets Aadapted to of different areas, which also communicate dle and elongated transversely. Within this socket is loosely mounted a pin 11, having at its lower end an enlarged head 12. Placed upon this pin is a coiled spring 13, the coils of which project beyondvthe end of the pin.

14 denotes a dog pivoted between the enlarged portions of the handle and having two engaging toes 15. The dog is provided with a lug 16, having a reduced free end 17, that is project into the upper coils of the spring.

When it is desired to rotate the head in one direction, the dog is turned upon its pivotpoint in the position shown in full lines in Fig. y6, and by reciprocating the handle back and forth the head will be rotated in that direction. To rotate it in the opposite direction, the dog isturned upon its pivot in the position shown in dotted linesV in Fig. 6, and in each adjusted position is retained by the tension of the spring, due to the fact that the headed pin is capable of being rocked from one position to the other in the socket and thespring exerting its tension in a directionl parallel with thepin. u

When it is desired to use the device as a drill, the bushing is removed and' the drillholder 18 is substituted. This holder is pro- Y vided with a feed-screw 19, having a head 20, adapted to be supported against some firm object, and isy provided with holes 21, by means of which a bar or other tool may be inserted for the purpose of rotating the screw and advancing the tool to its work.

22 denotes the bit, carried by vthe .drillholder.

From the .foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be understood without requiring an extended explanation.

The device works on the ratchet principle, and provision is made whereby it may be worked in either direction at the will of the operator.

Although I have specifically described the construction and relative arrangement of the several elements of my invention, I do not desire to be confined to the saine, as such changes or lnodications may be made as clearly fall Within the scope of my invention without departing from the spirit thereof.

I'Iaving thus described my invention, what I elaiin, and desire to secure by Letters Patent, is-

The combination with the handle having at one end two concentric rings and a transversely-elon gated socket, a head j ournaled in
