ROLLER WRENCH Filed March 2, 1951 A 33mm 22.42 M2.

dbtomq Patented May 31, 1932 UNITED STATES PATENT OFFICE FRED J. BURNS, OF SAGINAW, MICHIGAN, ASSIGNOR TO COLUMBIA MILLS, INCOB- (Ii POBATED, F SAGINAW, MICHIGAN, A CORPORATION OF NEW YORK V ROLLER WRENCH Application filed March 2, 1931.

This invention relates to wrenches, and more particularly to a wrench designed for winding shade or curtain rollers so that the winding mechanism may be properly tensioned.

Another object is to provide a wrench having a. foldable handle, which can be conveniently carried in the owners pocket, and which is of neat and pleasing appearance.

A still further object is to design a practical and substantial wrench of simple and rugged construction, made up of a minimum number of parts, and which can be readily manufactured and assembled.

With the above and other objects in view, the present invention consists in the combina tion and arrangement of parts, hereinafter more fully described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims, it being understood that changes may be made in the form, size, proportion and minor details of construction. without departing from the spirit, or sacrificing any of the advantages of the invention.

In the drawings,

Fig. 1 is an edge view showing my wrench in position on a shade roller.

Fig. 2 is an end View.

Fig. 3 is an enlarged edge View of the Wrench, the dotted lines showing the position of the handle when folded, and

Fig. 4 is a top plan view showing the handle folded.

To properly tension the winding mechanism of a shade roller it is necessary to rotate the spear, meanwhile holding the roller stationary, or vice versa; the simplest, most practical, and convenient method being to hold the roller in the hand, and then rotate the spear by means of a suitable tool, heretofore pliers, shade roller brackets, and other implements have been used for this purpose; these however, have not been entirely satisfactory, and I have therefore perfected a very simple, convenient, and practical roller wrench, which can be carried in the workmans pocket, or attached to a watch chain or key ring as desired.

Referring now more particularly to the Serial No. 519,439.

larged disk shaped head portion 8, slotted as shown at 9 to admit the spear member 6 as above described, said slot opening into a spear jaw 10 which is adapted to snugly fit said spear.

Laterally projecting wings 11 are formed integral and on opposite sides of the main body, and openings 12 are provided therein to accommodate the pin member 13, and on which the handle 14 is mounted, said handle being preferably round in cross section, the inner end being square as shown, and for a purpose to be presently described, an opening 15 being provided in the end of the main body to facilitate attachment to a chain or key ring.

Ears 16 are provided intermediate the length of the body and are also formed integral therewith, being bent upwardly and over to clamp and anchor one end of a spring member 17, the free end of which engages the butt of the handle 14 when the handle is in position, as shown in full lines in Figs. 1, 2 and 8 of the drawings, thereby holding it in open position, said spring being equally effective for holding said handle in its folded position, and as shown in dotted lines in Fig. 3 f the drawings.

In operation the wrench is attached to the roller spear as shown in Figs. 1 and 2, the operator holding the roller stationary, then proceeds to wind the spear until the meohanism is properly tensioned, inasmuch as the winding is a rotary motion it will-be clear that the strain is against the wings 11, so that there is no tendency to fold the handle. The operation is rapid and convenient, and greatly facilitates the installation and proper tensioning of the rollers.

From the foregoing description it will be obvious that I have perfected a very simple,

practical, and handy roller wrench for winding and tensioning shade rollers.

What I claim is:

1. A roller wrench comprising a stamped body member having an enlarged relatively flat head of substantially the same thickness as the body, a slotted jaw in said head and adapted to removably receive a roller spear, wings formed integral with the opposite end of thebody, a'hanolle pivotally mounted on said wings and foldable against said bodymember, and resilient means mounted on the body member for holding said handle in adjusted position.

2. A roller wrench comprising a stamped body member having an enlarged fiat head of substantially the same thickness as the body, a slotted jaw in said head and adapted to detachably receive a roller spear, laterally pro- 1 jecting wings on the opposite end of the body and formed integral therewith, a resilient member, ears formed integral with the body and adapted to anchor said resilient member, and a handle pivotally mounted on said wings and engageable by said resilient member in either open or folded position.

In testimony whereof I hereunto ailix my signature.

FRED J. BURNS.
