MELCHIOR MILLER AND ALFRED '.D. BURG, 0F LE MARS, IOWA.

WRENCH.

Specication of Letters Patent.

Patented Mar. 2l, 1916.

Application led December 2, 19x15. l Serial No. 64,725.

To all whom t may concern:

Be it known that we, MELCHIOR MILLER and ALFRED D. BURG, citizens of the United States, residents of Le Mars, county of Plymouth, State of Iowa, have invented certain new and useful Improvements in Wrenches, of which thefollowing is a speci,-

.fication pointed out in the claims.

In the accompanying drawings forming part of this specification, Figure 1 is a side view of awrench embodying our invention, partially in section, Fig. 2 is a view ofthe wrench, looking toward the opening between the jaws, Fig. 3 is a sectional view on the line of Fig. l, Fig. 4 is a sectional view on the line y-y of Fig. 2.

In the drawing, 2 represents the shank of the wrench, having jaws 8 and 4 formed thereon in a plane at rightl angles to the axis of the shank and having a socket 5 formed between them that is adapted to receive a bolt" head or bur on which the wrench is used. vWe propose to provide wrenches of different sizes having sockets of varying width to adapt them for the different sizes of burs and bolts and preferably the wrenches will be sold in sets of a suitable number, with sufficient variation in the sockets to adapt the tools for all burs and bolts that may be encountered in a machine or vehicle.

The end of the shank 2 opposite the jaws has ears 6 formed thereon with a space 7 between' them to receive a tongue 8 formed on the end of a handle 9 having shoulders l0 which are seated on the rounded ends of the ears. The tongue 8 has aV curved surface provided with ratchet teeth 11 and a pin l2 passes through the ears 6 and through said tongue and secures the parts together. A latch 13 is mounted in a socket 14 in the sitions where shank 2 and provided with a spring 15 which yieldingly holds the tapered end of the latch in 'engagement with the teeth of the ratchet. This handle 9 is free to swing through an arc of 180 degrees, as indicated by the full and dotted lines in Fig. 1, and may therefore shank 2 or in line therewith, or at any angle intermediate to the full and dotted line position. adapts the wrench for a variety of uses. It may be thrust in between the spokes of a wheel or pulley and can be inserted in poit would be utterly impossible to use a wrench of the ordinary type.

The handle is preferably provided with an end portion 16 having holes 18 extending therethrough at right angles to one another into which a punch or other suitable article may be inserted for the purpose of forming an auxiliary handle when the handle proper is in alinement with the wrench shank. The ratchet device will hold the handle in its different adjusted positions and provides a flexible joint which permits the convenient movement of the handle either to the right or the left, according to the position in which it is desired to place the wrench In various ways the details of construe'- tion herein shown and described may be modified and still be within the scope of our invention.

We claim as our invention:

1. A wrench comprising a shank having jaws formed thereon in a plane at right angles substantially to the axis of said shank, a handle hinged on the other end of said shank and provided with a hand grip, said handle having holes extending therethrough in which a supplementary handle may be inserted, 'the hingedy connection of said handle with said shank permitting it to be adjusted at an angle thereto, and means for holding said handle in its adjusted positions. Y

2. A wrench comprising a shank having a substantially fiat disk eccentrically mounted on one end of said shank in a plane aty right angles substantially to the longitudinal axis of said shank, said disk having a recess in one side thereof extending inwardly to a point adjacent the center of said disk and the wall of said shank, the walls of said recess forming jaws for gripping a nut or bolt-head inserted into said recess, a

be set at right angles to the hand grip -pivotally connected With the other end of said shank and free'to swing to a position in alinement With said shank or 'angularly With respect thereto, and means for holding said hand grip in its adjusted position, for the purpose specified.

3. A Wrench comprising a 'shank having a disk eccentrically mounted on one end of said shank in a plane at right angles substantially to the longitudinal aXis of said shank, said disk having a recess in one side thereof extending inwardly to a point adjacent the center of said disk and the Wall of said shank, the Wall of said recess forming jaws for gripping a nut or bolt-head inserted into said recess, a hand grip pivotally connected With the other end of said shank and free to swing to a position in alinement with said shank or angularly With respect thereto, for the purpose specified.

AIn Witness whereof, we have hereunto set our hands this 27 day of November 1915.
