Specification of Letters Patent.
Application filed January 14, 1910. Serial No. 538319.
To all whom it may concern:
Be it known that I, FRED H. Ssuvvrius, a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in I'Vrench'es, of which the following is a specification.
The object of this invention is to construct a ratchet wrench in which the handle may be given an oscillatory movementin tightening or loosening a nut.
In the accompanying drawings, Figure 1 is an elevation of my improved wrench in which a connect-ion is formed to loosen a. nut. Fig. 2 is a similar elevation in which a connect-ion is formed to tighten a nut. Fig. 3 is a section on dot-ted line a (r Fig. 4. Fig. 4 is an end view of the head showing the rectangular opening 15.
The wrench comprises the rest- 1, head 2 and intermediate crank section 3. The head 2. has a central bore 4 having one end 5 of less diameter than the other end, forming an internal annular shoulder. One face of this head is formed with ratchet teeth Send the.
other face is formed with ratchet teeth 7. A cylindrical socketmember 8 is rotatably mounted in the bore 4, and has a portion of less diameter that projects through said end 5. This member has an enlarged end 9 formed with ratchet teeth 10 that coiiperate with the teeth '7 of the head. The other end of the socket member is formed with screw threads 12, and a holding plate 11 is screwed on to said end and is rovided with teeth 13 that coti crate with t io teeth 6. It will be ohserv by reference to Fig. 3 that by forming the socket member with two portions of different diameters, a peripheral shoulder is produced that is located in opposition to the internal shoulder of the bore. It will also be noted by reference to Fig. 3 that the portion of the socket member which is of larger diameter, is of less length than the portion of the bore which is of larger diameter, and thus a space is left within the head and around the socket member between the'two opposing shoulders. In this space and surrounding the smaller portion of the socket member is a coiled spring 14:, the endsv of which respectively bear against the opposing shoulders. The action of this spring is to hold the ratchet teeth 13 of the plate 11 in engagement with the ratchet teeth 6 of the head 2,
as illustrated in Figs. 1 and 3.
By pressing against the nut 1, the ratchet teeth 7 of the head 2, will be moved into engagement with the ratchet teeth 10 of the end 9, as shown in Fi 2.
In use, the shank o a socket tool fitted to receive a nut is placed in the rectangular opening 15 in the cylindrical section 8, and the head is brought into engagement with the end 9 of the cylindrical section and by turning the crank ortion 3 to the right the tool is rotated, w ich will turn a nut, a
partial revolution may be given the crank portion as the nut becomes tight.
In loosening the nut, the spring 14 will force the head 2 into engagement withthe plate 11. By turning the crank portion to the left, the tool will be rotated, or partially rotated, which will loosen the nut.
The connection of the cylindrical section with the head 2 is'such that the axis of rota- Patented Jan. 31, 1911.

In testimony whereof I have hereunto so my hand in presence of two subscribing witnesses.
