SHADE-ROLLER.

SPECIFICATION forming part of Letters Patent No. 711,757, dated October 21, 1 02- Application filed January 2, 1902. Serial No. 87,994. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES H. BRIGDEN, of'

Canton, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Shade-Rollers, of which the following is a specification.

This invention relates to shade-rollers; and it consists in an improvement which includes means forming a permanent part of the shaderoller, whereby the automatically-actin g pawl or pawls which look the roller-body to the non-rotating spindle, so as to hold the shade at different fixed elevations, may be restrained from automatic action. This means may be arranged to hold the pawls out of locking position, in which case a shade-roller equipped for use at the top of the windowis converted into one more particularly adapted for use as a bottom roller, where it is ordinarily not desired to have an automatic locking action, the shade being, instead, held at differentelevations by a cord adj ustably secured or fastened to some fixture on the window-frame. The pawl-controlling means may be arranged to hold the pawls in looking position, which is desirable when the shade-roller is removed from its brackets with the spring in tension and it is not desired to permit the spindle to be accidentally released or when it is merely desired to have the shade remain at a fiXed height. Lastly, the pawl-controlling means may be arranged so as to be capable of holding the pawl or pawls either in or out of looking position.

Figure 1 represents a perspective view of one end of a shade-roller provided with my improved pawl-controlling mechanism. Fig. 2 represents an end elevation thereof with the pawls freed or capable of acting automatically. Fig. 3 represents an end elevation with the pawls held out of locking position. Fig. 4: represents a section on the line 4. 4 of Fig. 3. Fig. 5 represents anend elevation with the pawl-controllin g plate removed. Fig. 6 represents a perspective view of the pawl-controlling plate.

Fig. 13 represents a longitudinal see- Fig. 14 represents an end elevation showing another modified form of my invention with the pawls in freed condition. Fig. 15 represents a similar view with the pawls held out of locking position. Fig. 16 represents a perspective view with the pawls freed. Fig. 17 represents a longitudinal sectional view on the line 17 17 of Fig. 14. Fig. 18 represents a section on the line 18 18 of Fig. 14.

Fig. 19 represents a perspective view of the abutment-plate in this form of my invention. The same reference characters indicate the same parts in all the figures.

Referring to Figs. 1 to 6, inclusive, 2O represents the hollow rotatable shade-roller body, and 21 represents the spindle, adapted to be non-rotatably held in the slotted bracket, said spindle and roller-body being connected by The spindle 21 is formed with the usual notches 23, and the roller-body carries the usual automatically-acting pawls 24., pivoted at 25 to anend plate 26 on the roller-bodyand having teeth or projections 27, adapted to engage the notches 23. The pawls are also provided with pointed free extremities 28. 29 is a pawl-controlling plate held with some friction in the roller-body 20 and having two lips 30 3O struck from it at diametrically opposite points and turned inwardly. These lips constitute pawl-holding abutments, which are adapted to engage or free the pawls 2d. The plate 29 is provided with an outwardly-turned lip 31, which may be engaged by a suitable tool, so as to rotate the plate 29 with respect to the roller-body 20, whereby the position of the abutments 30 with relation to the pawls 24 is changed. An inwardly-turned longitudinal bead 32 engages the sides of the recess formed by bending out the lip 31 andforms a stop limiting the rotating movement of the plate. The one extreme position of the plate 29 clears the projections 30 from the pawls and permits the latter to act automatically in the ordinary manner, while the other extreme position of the plate brings the projections into locking engagement with the pawls. The projections are adapted to either engage the inner sides of the pointed extremities 28 of the pawls, as indicated in Fig. 3, thereby holding the pawls .ing engagement with the lips 35.

out of locking position and adapting the shade-roller to be employed as a bottom roller, or they may engage the outer sides of said extremities and hold the pawls in looking engagement with the spindle.

Figs. 7 to.13, inclusive, represent a form of my invention in which the pawls are adapted to be held only out of locking position. In this case a rotatably-adj ustable pawl-controlling plate 29 is provided with inwardly-turned projections 33 33, adapted to engage projecting heels 34 34 on the pawls 24. The plate 29 may be rotated tofree the pawls, as shown in Fig. 8, or to hold them out of locking position, as shown in Fig. 9.

Figs. 14 to 19, inclusive, represent a modification in which the pawl-controlling abutmen'rs are formed by lips 35 35, turned outwardly from a cup-shaped plate or ferrule 36,.

and the pawls 24 are pivoted to an outer rotatably-adjustable plate 37. In this plate are formed apertures 38, through which the lips 35 project and which are offset midway to form shoulders 39 40. The lips 35 are lodged in either half of the recesses 38, and each lip is given a partial twist, so as to engage it either with the shoulder 39 and one end Wall of the aperture or with the shoulder 40 and the opposite end wall of said aperture, whereby the pawls are either freed or held in look- In this form of my invention the pawls may be held either in or out of locking position. These lips 35 also serve when twisted to secure the outer plate 37 to the ferrule 36.

In Figs. 7and 13 the main part of the shaderoller body is shown as a cylinder 41, of penetrable material, such as wood, on the end of which is mounted a telescopic axially-adjustable metallic sleeve 42, carrying the fixable spindle 2landthelocking-pawls24. When the sleeve 42 is adjusted on the Wooden cylinder 41, the spindle and pawls and also the spring 22 move with it. It will be noted that the inner end of the spring is attached at 43 to the inner end of the spindle 21, while its outer end is attached at 44 to the plate 26, carried by the sleeve 42. formed in the sleeve 42, through which the tacks 46 or other fasteners for securing the shade to the roller-body are passed. These.

tacks when in place hold the sleeve 42 in the position to which it is moved on the cylinder 41. This improvement is not confined to the end of the roller carrying the iixable spindle.

It is obvious that various modifications other than those herein shown and described would come within the scope of my invention.

I claim 1. In a shade-roller, the combination of the spindle, the relatively rotatable roller-body, the automatically-acting pawl, adjustable pawl-controlling means permanently associated with the shade-roller, and provisions whereby the adjustment of said means permits or restrains the automatic action of said pawl.

2. In a shade-roller, the combination of the spindle, the relatively rotatable roller-body, the automatically-acting pawl mounted on the roller-body, a pawl-locking abutment mounted on the roller-body, and provisions for relativelyadjusting saidabutment and pawl rotatably with respect to each other.

In testimony whereof I have affixed my signature in presence of two witnesses.

CHARLES H. BRIGDEN.
