TURNBUCKLE-VRENCH.

Application led January 8, 1921.

Y 0 @ZZ whom t may concern.'

Be it known that I, CARTER J. JoHNsoN, a citizen of the United States, residing at Green Bay, in the county of Brown, State of l/Visconsin, have invented certain new and useful Improvements in Turnbuckle- Vrenches; and 1 do hereby 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.

This invention relates to new and useful improvements in wrenches and particularly to wrenches for turning turnbuclles.

One object of the invention is to provide a turnbuclrle wrench which when used longitudinally at the side of the turnbuclrle, will not rotate on the engaging pin as a pivot.

Another object is to provide a wrench of this character which will retain its grip on the turnbuckle when the operator releases his hold thereon.

Another object is to provide a novel means for holding' the transverse pin at one end of the wrench from falling out as the wrench is being turned.

A further object is to provide a turnbuclrle wrench which has a slidable pin for use in connection with small turnbuclrles.

Other objects and advantages willbe apparent from the following description when taken in connection with the accompanying drawing.

In the drawing: l

ing the pin in the openings of the legs of the end of the wrench.

Referring particularly t0 the accompanying drawing, 10 represents a tubular shell formed preferably of metal and having its opposite ends bifurcated to provide the pairs 'of longitudinally extending legs 11 and 127 the bifurcation at one end of the shell being formed in a vertical plane at right angles to that of the bifurcation at the other end. The legs 12 are perforated as shown at 13, with such perforations in alinement for the reception of a transverse pin 14.

vln the surrounding wall of the opening in one of the legs 12 there is formed a groove 15 in which is seated a coil spring 16, said l spring being adapted te snap into the groove 17 in the peripheral face of the end of the pin 1.11, to prevent the pin from accidentally slipping from the perforations 13 while the wrench is being rotated with the turnbuclle, in the manner shown in- Fig. 1. Within the shell 10, inwardly of the legs 11 there is disposed a metal plug 18, said plug being retained in the shell vby the transverse pin 19, and having the longitudinal central bore 2O in which is itted the pin 21. The portion ofthe pin 21 which projects from the end of the shell is disposed centrally between the legs 11, and is adapted to be engaged through the opening of thev turn- Ybuckle 22, in the manner shown in Fig. 3,

while the legs 11 engage on opposite sides of the turnbuckle. Secured to the inner faces of the legs 11 are bowed springs 23 which cooperate with each other te grip the turnbuckle in an embrace sufficient to maintain the wrench on the turnbuclrle should the Operator release his grasp on the wrench. Formed lcngitudi'nallyv in one side of the inner plug 18 is a` complementary plug section 18 in which is formed a longitudinal groove 31 for the reception of the removable transverse pin 14, when said pin is not in use in the legs 12. Secured in this groove 31 is a leaf spring 24 which frictionally engages the pin to maintain the saine in the groove. A transverse screw 25 maintains this plug section 18 in the shell. l

The plug 18 has a longitudinal pin 21 extending longitudinally therethrough which is held by the screw 26. The pin 21 is arranged to be projected into position between the legs 12 upon sliding movement of the section 18. The pin 21 is of smaller end will move from one face of the reduced Lef diameter than the pin 21 for the purpose of engagement in the opening of a smaller turnbuckle than can be accommodated by the pin 21. 0n the screw 26, which projects through a longitudinalv slot 27 in the shell 10, there is disposed a coil spring 28, one end bearing against the head of the screw while the other end bears against the washer 28. yThis washer is formed for engagement in the notches 10 in the shell at opposite sides o' the slot, Vto hold the screw and section 18 in its different slidable adjustments.

The inner end of the plug 18 is cut ol' obliquely, as is the inner end of the section 18 to form a recess 29 to receivey the reduced end of the section 18. `When the pin 21 is to be projected for use between the legs 12, the screw 26 is grasped and moved longitudinally in the slot 27 so that the section 18 will be moved and its obliquely cut end of the section 18. By loosening the screw 26 the pin 21 can be projected through the section 18 to a greater or lesser distance, so that the pin will project beyond the outer ends of the legs 12, thus enabling the operator to use thel pin on turnbuclrles which are in inconveniently reached places.

When the transverse pin 19, which is disposed through the shell and the inner plug section 18, is passed through the central opening of the turnbuclrle, the'adjacent'side of the turnbuclrle will lie in a longitudinal groove 30, formed in the side of theshell, thereby preventing the body of the turnbuckle from rotating on the pin as its axis. Thus the turnbuclrle and wrench body can be properly grasped and held while the wrench is rotated with the turnbuckle, in a direction above the longitudinal axis of the turnbuclrle.

Thus the wrench is capable of a number of different uses in connection with a turnbuckle, as well as being` capable of use with turnbuclrles oi' dierent sizes.

'lhe exterior of the shell of the wrench is lmurledorscored to insure a firm grip by the hand of the operator.

What is claimed is: f

1. A turnbuclrle wrench including a shell having a bifurcation at each end, each biurcation being formed in a plane at right angles to the other, the legs of the bifurcation at one end of the shell being formed with alining perforations, a removablepin disposed in said pertorations, and a resilient means carried by one leg or" the last-named bifurcation for holding the said pin against accidental displacement from the perorations.

2. A turnbuckle wrench including a shell having its opposite ends bifurcated with resultant pairs of longitudinally extending legs, a stationary plug in one end of the shell, a second plug movable longitudinally within the other end of the shell, a pin car` ried by the stationary plug axially of the lshell and lying with turnbuckle engaging end between the legs of the corresponding end of thepshell and a pin carried by the movable lplug and projecting therefrom and movable therewith into and out of position to lie with one end between the legs of the corresponding end of the shell.

3. A turnbuckle wrench comprising a shell having an end bifurcated with result ant spaced legs, said legs having alining pertorations, a pin removably engaged in the perforations, a plug slidably mounted in the same end of the shell, and a pin carried by the plug and movable therewith into and out of position to lie between the perforated legs of the shell.

4. A turnbuckle wrench comprisingr a shell having its ends bifurcated with resultant pairs of'spaced legs and having a longitudinal turnbuckle receiving groove in its outer face, a plug within one end of the shell, a securing pin passed through the shell and plug and projecting from the shell through the longitudinalgroove to engage a turnbuckle, a second pin carried by the plug `and lying with one end between the corresponding legs ofthe shell and a second plug slidably mounted in` the other end Vof the shell and having a pin movable therewith into and out of position to lie between the legs at that end of the shell-.

ln testimony whereof, I aiiix my signature, in the presence of two witnesses.
