WILLIAM A. FOX, OF NEWARK, NEW JERSEY, ASSIGNOR ONE-HALF TO FRANKLIN W. FORT,

. NEWARK, NEW JERSEY.

I SHADE-ROLLER WRENCH.

To all whom it may concern:

Be it known that I, WVILLIAM A. Fox, a citizen of the United States, residing in the city of Newark, county of Essex, and State of New Jersey, have invented a new and useful Improvement in Shade-Roller Wrenches, of which the following is a specification.

This invention relates to the ordinary andwell-known spring rollers for windowshades, and more particularly to means for adjusting the strength of said rollers with respect to their springs, so that the roller may be accommodated to difierent sizes and weights of shades, conveniently tightened when it has become weakened from use, and so forth.

The objects of the invention are to provide a tool for adjusting the tension of shaderoller springs; to provide such a tool with detent means for preventing the spring from unwinding and carrying the tool with it, if inadvertently released; to secure a simple and inexpensive construction; to provide in combination with such tool a hammer, screw-driver andtaek-puller, and to obtain other advantages and results as may be brought out in the following description. V

The invention consists in the improved shade-roller wrench, substantially as will be hereinafter described and finally set forth in the claims. I

Referring to the accompanying drawings, in whichllke characters of reference indicate corresponding parts in each of the several figures; Figure 1 is a plan of my improved shade-roller wrench; Fig. 2 is a side elevation of the same; Fig. 3 is a plan of the end of a shade-roller with my wrench applied thereto inuse; Fig; 4 is a view similar to Fig. 3, but showing a modified form of holding dog; Figs.'5 and 6 are sections taken transversely and longitudinally of the wrench-body, respectively, and illustrating the said modified form of dog; Fig. 7 is a sectional view taken on line mzc, of Fig. 4:, and Fig. 8 shows in plan the end of a shaderoller with a wrench having another modification of holding dog applied thereto.

In said drawings, 2 indicates the beam or body portion of my new wrench, having at one end a handle 3, which is preferably Specification of Letters Patent.

formed, as' shown, by bending up an end portion of the body 2. The other end of the body portion is adapted to engage the flattened end 4L, of a shade-roller shaft, as by means of an aperture 5, which its over said end 4:- Beyond said aperture 5, the extremity of the wrench body 2, is beveled downwardly, as at 6, and through the said beveledface extends a set-screw 7, which projects into the said aperture 5, to engage the shade-roller end l, and clamp the wrench thereto. Thus by turning the wrench, when applied, the spring of the shade-roller may be wound up, as will be understood, or by holding the shade-roller vertically so that the pawls 8, 8, thereof are idle, the spring can be unwound.

In order to prevent the shade-roller spring from unwinding, and carrying the wrench with it, in case the wrench is prematurely or inadvertently let go, I provide upon the body of the wrench a dog adapted to he by gravity against the end of the shaderoller and engage the pawls 8, 8, thereof to arrest backward movement. This dog preferably comprisesa reduced shank 9, pivotally entering a horizontal boring extending transversely through the wrench body from side to side, and secured at its extremity by a washer 10, outside of which the shank is upset. Adjacent to said shank the dog is of rectangular cross-section, as at 11, and lies in a lateral recess 12, of the beam, the front and rear walls of which recess form stops, respectively, to limit swinging of the dog into idle position as shown in Fig. 2, or beyond operative position as shown in outline in the same figure. The said dog is further provided wit-h a finger-piece 13, for changing its position, and at its outer end is curved downward and rearward, as at 14:, to engage the pawls 8, S, of the shaderoller. In the construction shown in Figs. 3 and I, this dog abuts against the ends of the pawls 8, 8, forcing them outward as shown, but in the wrench 15, shown in Fig. 8, I'have so formed the end 16, of the dog the construction shown in F igs. 4, 5, 6 and 7 where 18, indicates a wrench body in which a dog shank 19, is vertically seated and provided at its end beneath the beam with a forked extremity 20, in which the dog proper, 21, is pivoted. Said dog then swings transversely of the beam and is adapted to drag around in a circle to engage the pawls 8, 8, within the flange or rim 24, of the shade-roller end. It will be understood that the slot or aperture 5 in the body portion of the wrench, by reason of its fitting the flattened end a of the shaderoller shaft as above set forth, definitely determines the position of the wrench dog with reference to the shade-roller pawls, and thus insures that in the act-ion of the tool the said parts shall accurately engage to prevent backward turning. The said handle 3, of the wrench is preferably formed into a hammer head, as shown, and the edge of the opposite beveled end of the wrench body provides a screw-driver 22, having a slight notch 23, at its middle, to serve as a tack-puller. Thus all the tools necessary for mounting shades upon rollers, and for mounting the rollers upon window-frames, are provided in immediate connection with my wrench.

In the modified construction shown in Figs. at, 5, 6 and 7, the shank 19, is preferably riveted tightin its place as shown.

Obviously, the wrench-body might engage the spring-shaft extremity otherwise than by having the aperture 5, to receive it, the location of the 'set-screw 7, might be changed, many different kind of dogs might be employed, and other variations from the exact construction shown and described be made, without departing from the spirit and scope of the invention. I do not intend, therefor, to limit myself by any positive descriptive terms herein employed, except as the state of the art may require.

Having thus described my invention, what I claim as new is 1. As an article of manufacture, a shaderoller wrench comprising a body portion adapted to grasp the end of the spring shaft of a shade-roller which projects beyond the roller proper, and detent means 011 said body portion adapted to project there-from toward the end of the shaderoller from which said spring-shaft pro jects and engage the same in one direction of turning of the wrench, while freely passing over it in the other direction.

2. In a shade roller wrench, thecombination of a body portion adapted to receive the flattened end of the spring-shaft of a shade-roller which projects beyond the roller proper and be located thereby with respect to said roller proper, and means at a fixed point of said body portion adapted to project therefrom toward the end of the shaderoller from which said spring-shaft projects and engage one of the shade-roller pawls at its outer side and force the same into locking position in one direction of turning of the wrench while freely passing over said pawls in the otherdirect-ion of turning of the wrench.

3. The herein described shade -roller wrench, comprising a body-portion adapted to grip the end of the spring shaft of a shaderoller which projects beyond the roller proper, and a dog pivoted upon said body-portion to swing toward and away from the end surface of the roller from which said spring-shaft projects.

5. The herein described shade roller wrench, comprising a body portion adapted to grip the end of the spring-shaft of a shade roller which projects beyond the roller proper, and a dog adapted to project from the plane of said body portion toward the end surface of the roller from which the spring shaft projects, said dog being adapted in one direction of turnin of the wrench to pass the pawls of said rdller end and in the other direction to engage said pawls to operate them without passing them.

6. The herein described shade roller wrench, comprising a body-portion adapted to grip the spring-shaft, a dog pivoted on said body-portion with its free end adapted to engage the shade-roller pawls as the wrench turns or to be shifted to idle position.

7. The hereindescribed shade-roller wrench, comprising a body-portion adapted to grip the spring-shaft, and a pivoted dog projecting laterally from said body-portion with its extremity adapted to engage the shade-roller pawls, said dog being adapted to be thrown into either idle or operative position.
