M. O. GOLDSMITH ROLLER WINDOW SCREEN June 12 Filed April l5, 1925 Patented June 12, 1928.

UNITED STATES MAURICE O. GOLDSMITH, OF BOSTON, MASSACHUSETTS.

ROLLER WINDOW SCREEN.

Application filed April 13, 1925.

The principal object of my invention is to provide a roller window screen which, when in use, will be held firmly at its side edges and my object more particularly is to do such holding by mechanism which will bc simple and effective.

A feature of my invention is that the screen itself keeps the holding means out of holding engagement while the screen is moving.

Another feature lis that the means for moving the holding means out of holding position is carried by the screen itself.

Another feature is that the holding means moves automatically into holding position when the screen is fully unrolled.

Other features will be pointed out below.

Figure l is a partial elevation partly in section of a. portion of a window equipped with my invention;

Figure 2 is a section on line 2-2 of Figure l;

Figure 3'is an enlarged sectional detail on the line 3 3 of Figure 1;

Figure 4 is a Sect-ion on line 4-4 of Figure l; and

Figure 45 is a detail hereinafter described.

rThe window withwhich my screen may be used may be of ordinary construction and may comprise the frame A, the sill B, the upper sash D and the lower sash E.

Suitably fixed to the frame is a box F having an end wall f with a rectangular slot f, there being a similar wall at the other end of the box. Pintle G is provided with a rectangular extensionv g to enter slot fand has fixed to it at g one end of coiled spring g2. This spring is operatively connected in any well known way to the roller H and tends to roll up the wire screen J, the latter being fixed to the roller at y'.

Fixed to the bottom of the screen, at the front thereof, is a plate K, preferably held to the screen and to the rear plate K by rivets 7c. A finger piece. whose function will be described.below` is pivoted to plate K at ZA and comprises upper portion L and lower portion L the latter having a lug at Z to be raised by the user, the weight or portion L tending to hold that portion normally against stopte. A similar finger piece (not shown) is pivoted to the opposite end of plate K.

An angle iron comprising portions M and M is suitably held in place, the portion M providing aface against which one side edge Serial No. 22,574.

of the screen is clamped as described below and the portion h forming a support for brackets m and m, which are held in place by screws, which screws may also hold portion M to the window frame.

Brackets m and m are perforated to form pivot bearings for the ends of shaft N2 which is rigidly secured to angle iron N N said ends projecting above and below said angle iron N N in order to enter the perforations in the brackets. Portion N has an eye n connected to coiled spring n which in turn is connected to eye n2 fixed to portion M (as clearly appears in Figure 4) and therefore spring fn. tends to force portion N to the right in Figure 4@ so as to clamp the side edge of the screen firmly in place in order to exclude insects or other undesired objects.

It will be noted that portion N is at .an angle with portion M with the result thatany pull on the screen in a direction to the right in Figure 4 Will tend to increase the clamping action.

Similar springs n and n, similarly mounted, are provided and, of course, any

` desired number might be used.

Portion N is notched at 'a5 to receive one end of plate K, the upper end of the notch forming a. shoulder to prevent undesired upward movement of plate K and conse quently of screen J.

It will be understood that V'for the. other .side edge of the screen lf provide similar sets of angle irons and cooperating springs.

The screen is held unrolled, as in Figure '1, principally by the engagement of member K with the top wall of the recess or notch n although, if desired, the strength of the springs n3, n and n4 may be such as to clamp portions N against the screen. Vhen it is desired that the screen be rolled up the lugs Z are raisedwith the result that portions L are forced outwardly and press portions N toward portions Mj so that the notches n are moved out of the path of portion K and consequently the screen may be rolled up. During the upward movement the portions L may be held in their outward positions or the fingers of the user may be removed from the lugs Z and the screen may be pushed up at the middle portion K and in such case the ends of portion K will hold portions N out of engagement with the screen and said portions will be pushed so far toward portions M that there will be substantially no clamping action Aof portions CIK N on the ends of portion K. The result is that the screen may be rolled up until the lugs Z engage the bottom of box F Where the screen Will remain until it is desired to unroll it. Vhenthe screen is rolled up the portion K will be above the tops of portions N.

/Vhen the screen is to be unrolled the portion K is pulled downward and the curved portion 7: will engage the top oli portion N (and of the corresponding portion N at the other side of the` Window) and will force these `portions toward the portions lv" so that portion vK may be moved down and the screen unrolled until portion K is opposite notch whereupon the vertical edges of portions N automatically move against the screen and hold it against the inner faces of portions M so that vall undesired things Will ybe excluded.

I prefer to have the member K extend clear across the screen as does member K and member K is preferably to be curved at yits lower corners like the curving of member K. V
