FLEXIBLE WRENCH.

SPECIFICATION lforming part of Letters Patent No. 771,376, dated October 4, 1904.

l Application filed April 30, 1904. Serial No. 205.701. (No model.)

To all whom it may concern: Y

Beit known that I, HENRY Lox'rERKAMP,'a citizen of the United States, residing at Roselle, in the county of Carroll and State of Iowa, have invented certain new and useful Improvements in Flexible Wrenches, of which the following is a specification.

My invention relates to that class of devices commonly known as flexible wrenches, and aims especially to provide an improved form of wrench which may be manufactured at a minimum cost and embodying an exceedingly simple and serviceable arrangement of parts as regards the structure thereof.

Generally describing my invention, the same comprises a handle-lever and a exible, preferably metallic, band adapted to encircle a part so as to bind thereagainst upon operation of the handle-lever to unscrew said part or to otherwise manipulate same.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings.

While the essential and characteristic features of the invention are susceptible of modiiication, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of a Wrench embodying my invention. Fig. 2 is a plan view. Fig. 3 is a detail perspective view of one of the complementary members comprising the handle.

Corresponding and like parts are referred /to in the following description and indicated is indicated Vby the numeral 2. In order to secure a maximum degree of cheapness in the manufacture of my wrench, the handle-lever is constructed of complementary or similar bars 3 of fiat form, and these bars are secured together at corresponding ends by means of suitable fastenings, so that the adjacent sides abut. The meeting portions of the bars 3 of the handle-lever extend the major portion of the length of the said lever and constitute the handle, which is grasped in the operation of the wrench. The ends of the bars 3 opposite to those which are secured together, as above mentioned, to form the handle 1u are deflected from each other to form spaced arms 4, which arms are provided with two pivot members 5 and 5f. The pivot member 5a is disposed at the ends of the spaced arms, connecting these arms at each portion, wherein the pivot member 5 is located some distance away from the member 5 and adjacent the handle l. The band 2, whichis made of steel metal preferably, is secured at one end to the pivot member 5 and at the other end is secured to the pivot member 5, so that movement of the lever will tend to cause the band to bind against the part which is being operated upon. In the operation of the device after the same has been so disposed as to embrace the part which is to vbe operated upon the end pivot member 5 constitutes the center `of axis upon which the handle-lever 1 pivotally moves, whereas the pivot member 5 draws the exible band 2, so as to effect the binding action thereof.

It is advantageous that the flexible band 2 be normally held open, and in order to positively cause the band 2 to spring into a position so as to likewise be ready for application to a part preparatory to use of the wrench lugs 6 are projected inwardly from the inner sides of the spaced arms 4 of the handle-lever, and these lugs engage the band 2 as the same is tightened about a part. The engaging coperation of the lugs 6 with the band tends to throw the lever into a position causing the band to loosen about the object which is embraced thereby as soon as the pressure upon the handle-lever is relieved.

Having thus described the invention, what is claimed as new is- IOO In a Wrench of the class described, the cornto the pivot members upon the spaced arms, bination ot' a handle-lever composed of comand lugs projected from the inner sides of the plementary bars secured together in abutting spaced arms between the pivot members and relation throughout the major portion of their cooperating With the band to hold same in an I5 length, corresponding ends of said bars being open position. deflected from each other to form spaced ln testimony WhereofIafX my signature in members, a pivot member carried by the outer presence of two Witnesses.
