ROLLER-SCREEN.

SPECIFICATION forming part of Letters Patent No. 766,541, dated August 2, 1904.

Application filed October 12. 1903. Serial No. 176,685. (No model.)

To rI/Z-Z whom, it ntrty concern:

Be it known that I, FREDERICK MoLLnDoRE SPIEGLE, a citizen of the United States,and a resident of the cityof New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved RollerScreen, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved roller-screen to r use on windows, piazzas, and other places desirable to be screened against flies, mosquitos, and other insects and arranged to permit convenient and easy unrollingot' the screen for screening purposes, to allow rolling the screen up to be completely out of the way when not in use, and to prevent bulging of the screen when in use.

The invention consists of novel features and parts and combinations of the same, as will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a front elevation of the improvement as applied to a window. Fig. 2 is an enlarged sectional side elevation of the same. Fig. 3 is a transverse section of the same on the line 3 3 of Fig. 2. Fig. l is a sectional plan view of the same on the line l 4 of Fig. 2. Fig. 5 is a perspective view of one of the bearings. Fig. 6 is an enlarged side elevation of the spring locking device for the screen, part of the end bar being removed; and Fig. 7 is an enlarged rear sectional side elevation of the operating mechanism for the locking device.

The roller-screen illustrated in Fig. 1 is arranged to screen or unscreen the lower half portion of a window; but it is evident that the device may be readily employed for screening the entire window or for screening piazzas or other parts of buildings.

The casing A of the roller-screen, as shown in the drawings, is secured at its ends to the sides of a window-frame B, and in the ends of the said casing is jonrnaled a spring-roller C,

on which winds and unwinds a web D, of screen material, such as pliable wire-netting. The bottom of the casing A is provided with a slot A, extending lengthwise ot' the casing throughout its length, and through this slot passes the screen-web .l) to screen the lower portion of the window when the lower sash B thereof is raised.

The end of the screen is provided with a suitable cross-bar E, having a knob E or the like for conveniently pulling the screen-web down whenever it is desired to screen the window, as mentioned.

The sides of the screen-web are provided .with fixed spaced bearings F, adapted to engage guidewavs Ur, secured to the sides of the window-frame B, the said bearings serving to protect the side edges of the screen-web against unraveling, to strengthen the screen-web, and to prevent the screen-web from bulging by gusts of wind or the like at the time the screenweb is extended to cover the window-opening.

Each of the bearings F is preferably made of metal and consists of a head F and two members F F, engaging the screen-web at option G of the guideway G, which tubular portion is split on the outer side and connected with side walls (i between which pass the members F of the hearing, as plainly indicated in Fig. 4, so that the screen-web 1) does not come in contact with the side walls of the guideway or any other part thereof.

It is understood that the head F of each bearing is somewhat larger than the space between the side walls G, so that the head F prevents sidewise movement of the web D, and as both sides of the screen are engaged by their bearings F with the guideways Gr it is evident that the screen-web cannot bulge when subjected to a transverse strain, such as a gust of wind or the like.

As the bearings F are spaced apart, it is evident that the frictional contact of the several bearings with the guideways is reduced to a minimum, so that it takes but little power on the part of the operator to pull the screen 7 down and also little power of the spring in the roller C for turning the roller to Wind up the screen.

As the side edges of the screen between adjacent bearings F extend between the side Walls G of the guideways, it is evident that the said side edges are protected and are not liable to unravel or be otherwise injured.

The guideways G extend with their upper ends close to the casing A, the slot A of which is in register with the openings in the tubular portion G, and the space between the side walls G and the end walls of the casing at the slot A are preferably rounded off, as indicated in Fig. 3, to allow an easy movement of the screen-web through the slot A to the guideways Without creating undue friction or binding of the screen-web.

In order to lock the screen-web in any extended or unwound position, the following device is provided: The shank E of the knob E is journaled in the end bar E and carries arms E connected by wires or links E with the free ends of spring-catches E secured on the terminals of the end bar E and adapted to engage notches G on the inner edges of the guideways G, as plainly shown in the drawings. By turning the knob E in one direction a pull is exerted on the spring-catches E to disengage the same from the notches Gr to unlock the screen-web-and to allow rewinding of the screen-web by the revolving roller C or to allow of pulling the screen-web down on the operator exerting a downward pull on the knob E. The links E extend from the diametrical arms E in opposite directions, and preferably within recesses formed longitudinally in the end bar E, as plainly shown in Figs. 6 and 7. When the screen-web has reached the desired position, the operator releases the knob E, so that the spring-catches E by their own resiliency snap into adjacent notches G? to lock the screen-web in position and simultaneously on both ends of the end bar E. v

The roller-screen described is very simple and durable in construction, can be cheaply manufactured and readily applied to windows and other devices, and the screen-web can be readily unwound from its roller C for screening purposes or allowed to wind up on the said roller to be inclosed in the casing A and be out of the way when not in use.

It is understood that the spring-roller O is of the usual construction, preferably of the Hartshorn type, so that further description of the same'is not deemed necessary.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A roller-screen comprising a casing for attachment to a window-frame or the like, said casing extending from one side of the Windowframe to the other and having a slot extending lengthwise in the wall of the casing, a spring-roller journaled in the ends of the said casing, a screen winding on and unwinding from the said spring-roller and provided at its sides with spaced bearings, each consisting of two members, fixed to opposite sides of the screen-web and heads on the outer ends of the members, projecting beyond the corresponding side edge of the screen, and fixed upright guideways for the bearings to slide in, each guideway having a split tubular portion for the heads of the bearings and spaced side walls for the bearing members, said. side walls being extended and formed into return-bends terminating at their extremities in flanges for securing the guides to the Window-facing, the upper ends of the said tubular portion and the spaced side walls registering with the said casing-slot, at or near the ends thereof, as set forth.

2. A roller-screen provided with a springroller, a screen-web Winding up and unwinding on the said roller and having an end bar,

fixed upright guideways for the sides of the screen-Web, provided with notches on their inner edges, and a locking device on the screen-Web bar, comprising a knob mounted to turn, springs forming catches on the terminals of the end bar projecting outwardly therefrom and adapted to normally engage the said notches and a connection between the spring-catches and the said knob, as set forth.

3. A roller-screen, comprising a screen-Web, guideways for the side edges of the screen- Web, said guideways having notches, an end bar on said web, said end bar having a bearing, a locking device for the screen-web comprising a knob mounted to turn in said bearing in the end bar, links extending from the knob in opposite directions, and angularshaped springs forming catches, each catch having one end secured to the end bar of the screen-web, and the other end connected with one of said links, the said spring-catches being adapted to engage said notches on the guideways for the screen-web.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
