COMBINED ADJUSTABLE SCREEN AND YVINDOVV -SHADE FIXTURE.

SPECIFICATION forming part of Letters Patent No. 443,315, dated December 23, 1890.

Application filed June 20, 1889. Serial No. 315,016. (No model.)

To all whom it may concern:

Be it known that I, THOMAS CHOPE, of the city and county of San Francisco, State of California, have invented certain new and useful Improvements in a Combined Adjustable Screen and Window-Shade Fixture; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention consists, broadly, of a screen carried on a roller at the top of the window, said screen supporting at its lower end aroller with its curtain, by which combination the space at the top of the upper sash (when the same is drawn down for ventilation) may be covered with the screen to prevent the entrance of insects or dust, and whereby also the effects obtained from the ordinary curtain may be accomplished with equal success.

In this device either the screen or curtain may be operated separately, or both may be operated together.

In the accompanying drawings, Figure 1 is a front view showing the screen and curtain partly drawn down. Fig. 2 isa side elevation of the same, the parts being in the same position in full lines, the dotted lines representing the curtain-roller at the upper end of the run. Fig. 3 is aperspective view showing the curtain-roller bracket with friction spring. Fig. i is a plan view; Fig. 5 represents the bushings for the screen-roller, and Fig. 6 is a plan view of a horizontal section through the window-frame, showing the parts in plan view.

In the drawings, a represents the ordinary self-acting spring-roller. This is placed at the top of the runwayof the inside or bottom sash. The screen B has one end secured to this roller. The roller is of special form to admit of it being conveniently placed. 7 It is journaled in the bushings J J, inserted in the face of the runway. The roller is shorter than the distance between the bushings, and at one end is provided with a long journalpin y. On this end of the roller there is a spring-cap O, which is forced normally outward by means of a spring D within the cap. The cap has longitudinal movement on the end of the roller; but it is held by a pin a, passing through a slot c in the cap, which prevents rotary movement of the cap. In

placing the roller inposition the pin y is inserted into the bushing J, and then the roller is forced longitudinally toward the right, Fig. 1, against the pressure of the spring D, until the roller has been shortened enough to permit the bearing on the left-hand end to be properly positioned in front of the opening in the bushing J, when by easing up the. pressure the spring D will force the roller toward the left and properly seat the bearing. At the lower end of the screen and arranged to move inthe upper runwayoftheinsideorlower sash is a bracket G, connected to the screen by the dovetailed slats H. This bracket carries in the ordinary manner the well-known form of spring-roller E, to which is secured the curtain I. The bracket has curved bearings h to receive the slats H and the ordinary bearing-sockets h for the journals of the curtain-roller. A spring F is attached to the brackets extending upwardly therefrom to bear upon the head of the runway, and thus act as a bearing-surface in the up-and-down movement of the bracket. A pin K is also provided on the bracket, which likewise acts as a bearing against the bead when the chain S is drawn upon, said chain S being intended to operate the bracket to lower the screen. The spring of the upper or screen roller is stronger than that of the curtain-roller. In order to lower the screen, the chain S is pulled upon, While the curtain may be operated independently of the screen and with the curtain in any part of the runway by pulling upon it, the stronger spring of the screenroller acting to hold the screen and its roller against movement during the operation.

It will be noticed that a decided advantageous result is obtained from the combination of the screen with a roller having a springcap, as it is essential, in order to secure perfoot results, that the screen extend entirely across the opening and within the runway,

and this is accomplished by journaling the screen-roller within the runway, this being permitted by means of the spring-cap.

I claim- 1. Incombination, the screen, the roller therefor having a spring, brackets connected to and supported by the lower edge of said screen, a roller in said brackets having a f). In c01nbination,the roller havinga jour- 1o spring, and a curtain carried by said roller, rial-pin y fixed rigidly at one end, and a substantially as described.
