CHARLES BORGESON, OF PITTSBURG, PENNSYLVANIA.

WRENCH.

SPECIFICATION forming' part of Letters Patent N0. 671,789, dated April 9, 1901.

Application filed July 28.1900. Serial No. 25,080. (No model.)

To @ZZ whom it may concern/.-

Be it known that I, CHARLES BoRGEsoN, a citizen of the United States of America, re-

siding at Pittsburg, in the county of Allef scription thereof, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to certain new and useful improvements in wrenches, and has for its object the provision of novel means whereby the wrench will be automatically disenl gaged from the nut, shaft, or square ends requiring a wrench for adjustment.

The invention has for its further object to construct a wrench of the above-described character that will contain comparatively few parts that are not liable to become out of order and when broken may be easily replaced.

The herein described invention further aims to construct a device of this character that will be extremely simple in its construction, strong, durable, and comparatively inexpensive to manufacture; furthermore, one that will be highly efficient in its operation.

With the above and other objects in view my invention finally consists in the novel construction, combination, and arrangement of parts to be hereinafter more particularly described, and specifically pointed out in the claims.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, and wherein like numerals of reference indicate like parts throughout the several views, in which- Figure 1 is a perspective view of my improved wrench. Fig. 2 is an enlarged longitudinal vertical sectional view of the lower or engaging end of the wrench. Fig. 3 is an end view of the wrench as shown in Fig. 2.

In t-he drawings the reference-numeral 1 indicates the body portion of the wrench; 2, the handle thereof. 4 indicates the lower enlarged cylindrical portion of the same, the latter being provided with a square chamber 5 and outwardly-extending guideways 6, arranged diametrically opposite each other.

The referen ce-numeral 7 indicates a spring` pressed follower having arranged on its rear face a shank 7a. The said follower is further provided with guides 8, adapted to register with and operate in the guideways 6. A spiral spring 9 is arranged within the chamber 5, having its one end secured to the shank '7a of the follower and its other end fastened to a lug l0, extending into the chamber 5, by means of a pin ll, the latter passing through suitable apertures formed in the enlarged cylindrical portion and the lug.

The parts when assembled are arranged in such'a manner that the follower will almost be iush with the end of the enlarged cylindrical portion when the spring is in an exi panded position.

The operation of the device is as follows: The square end of the wrench being adapted to engage the part to-be adj usted in the usual manner, a slight pressure being exerted, thereby depressing the spiral spring and forcing the follower into the chamber, the guides riding in the guideways rearwardly until the pressure is released, when the follower will be forced to its normal position by the expansion of the spiral spring, which will tend to automatically free the object from engagement with the wrench.

It will be understood that the chamber and engaging end of my wrench, although shown as square for the purpose of illustrating my invention, may also be made in the shape of ahexagon, Octagon, or any other desired form and that any convenient form of handle may be adopted and that other minor changes in the construction may be made without de parting from the general spirit of my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is- Y l; As an improved article of manufacture, a socket-wrench consisting of a body portion having formedtheren a chamber and guideways, and provided with a spring-actuated follower and guides for operating in said guideways, substantially as specified.

2. A device of the character described, consisting of 4a suitable handle, a body portion having formed therein a chamber and guide- IOO ways, a follower carrying guides adapted to In testimony whereof I have hereunto afoperate in said gui'deways, a spiral spring ar- Xed my signature in the presence of two sub- 1o ranged within said chamber having its one soribing Witnesses.

end connected to said follower and its other end connected to a. lng extending into said CHARLES BORGESON' chamber, all the parts being constructed and Witnesses: operating substantially as herein described t JOHN GROETZINGER,

and for the purpose set forth. H. `E'. BECKER.
