PAWL FOR SHADE-ROLLERS.

SPECIFICATION forming part of Letters Patent No. 781,655, dated February '7, 1905.

Application tiled October 20, 1904. Serial No. 229,326.

In fly/7 H'mm ft 71mg/ cm1/cern:

l-e it known that I, WILLIAM D. JANEs. a citizen ot' the United States, residing at Saginaw, in the county ot' Saginaw and State of Michi- 3 gan, have invented certain new and useful Improvements in Pawls for Shade-Rollers; and I do hereby declare the following to be a full, clear, and exact description ot' the invention, such as will enable others skilled in the art to D which it appertains to make and use the same. This invention relates to shade-rollers, and pertains more particularly to certain constructions and arrangements in the pawl-plate or cap ot a shade-roller whereby the pawls may be held back out ot contact with the notched spear ot' the roller, thereby rendering the pawls inoperative.

As is well known, shade-rollers designed to operate with downwardly-hanging shades are D provided with pawls in the shade-roller cap to Alock the roller at any desired position. On the other hand, when the shade -roller is mounted at the bottom ot' the window and carries an upwardly-moving shade action ot' 3 the shade-roller pawls is not desired.

lt is the object of my present improvement to provide means by which the pawls can be rendered inoperative, and thereby make the roller suitable for use at the bottom ot' the window and adapt it to operate an upwardlymoving' shade.

My improvement is shown in the accompanying drawings, in which-*- Figure l is an enlarged face view of a shade- 3 roller cap embodying my improvement. Fig. is a similar view broken away in part; and Fig. 3 is a transverse section taken on the line 1' a( ot' Fig. 2, the outer plate ot' the shaderoller cap being removed. l is the outer plate ot' the shade-roller cap,

and 2 is the inner plate.

3 is the shade-roller spear that projects through the openings in the two plates.

Between the outer and inner plates are the usual pivotally-mounted pawls et and it, adapted to engage the spear 3. As hereto't'ore constructed these pawls are free to move back and forth as the cap revolves with the roller, and no means is provided tor locking the pawls back to preventtheir engaging with the spear, as above noted. ln my present device I provide holes 1xl and lh in the outer plate l, so located as to register with the notches i" ot' the pawls 4 and et when the latter are drawn back out ot' engagement with the spear 3. In the inner plate 2 l provide corresponding holes 2 and EZ". lhese holes are preferably rectangular in form and are made by punching down the metal ot' the plate 2, so as t0 form a downwardly projecting jflange Q". These ianges when driven into the end ot' the shade-roller lock the inner plate Q in position on the end of the roller. The holes l" and 2 and l" and 2", respectively, register with cach other, so that a small pin, the end ot' a match, or other suitable stop may be passed through them after the pawl has been moved back to the position shown by dotted lines in Fig. 1, which etfectually prevents the pawl from engaging the spear.

lVhat l claim as my invention, and desire to secure by Letters Patent, is as follows:

In a shade-roller cap, the combination with the pivotally-mounted pawl having a notch, olj an inner and an outer plate, each having a perforation registering with the notch ot' said pawl when the pawl is drawn back.

YIn testimony whereot' IV aliix my signature in presence ot' two witnesses.
