WINDOW-SCREEN.

Specification of Letters Patent.

' Patented Ju1y 2, 1907.

Application filed March 19,1907- Serial'No. 363,268.

To all whom it may concer'm.

Be it known that I, SAMUEL EDGAR SNnnnKER, a citizen of the United States, and a resident of White Plains, in the county of Westchester and State of New York, have invented a new and Improved Window- Screen, of which the following is a full, clear, and exact description. i

This invention relates to window screens, and is particularly useful in connection with devices of this character in which the screen, intended to prevent the entry of insects, dust and the like through the window, is adjustable.

The. object of the invention is to provide a simple, strongand durable window screen, in which the screen is supported upon a roll and in which the screen may be adjusted and secured in position as desired.

The inventionconsists in the construction and combination of parts to be more particularly described hereinafter and fully set forth in the claims.

' Reference is to be had tothe accompanying drawings forming a part of this specification, in which like characters of reference: indicate corresponding parts in all the views.

Figure 1 represents a window screen frame showing my device applied thereto; Fig. 2 is a side elevation of the window screen; Fig. 3 is a vertical cross-section .of the device; and Fig. 4 is an enlarged horizontal section of a detail.

Referring more particularly to the drawings, I provide a supporting frame 2 which is adapted to be fixed in position in a window-frame 1 of the usual construction, as shown most clearly in Fig. 1. The supporting pose. The weights 8 are arranged to slide upon ver ticalguides 1O consistingof rods of metal or other suitable material vertically mounted upon the lateral. members of the supporting frame 2. The arrangement is such that if the weights 8 slide downward upon the guides 10*the cords 7 are unwound from the drums, thereby rotating the roll 4 and thus winding up the screen upon the roll. When the screen is unrolled from the roll 4' the weights are moved upwardly upon the guides. The free end of the screen 5 is provided with a cross-piece 11 for a purpose which will appear hereinafter.

I provide a holding frame 12 adjustable with respect to the supporting frame in a direction substantially perpendicular therewith. The holding frame comprises lateral members and a cross member joining the upper extremities of the lateral members. Brackets 13 are rigidly mounted upon the lateral members of the supporting frame adjacent to the lateral members of the holding frame, by means of laterally disposed toes l4 "securedin position by means of screws or bolts 15. The brackets 13 extend outwardly beyond the holding frame and at their outer extremities have slots 16 within which are slidably located the laterally disposed ends -18 of levers 17. The extremity of the end 18 of each lever 17 is secured to a holder 19 rigidly mounted upon a lateral member of the holding frame. The opposite end 20 of each lever 17 is bent and is pivotally secured to a rod 21 substantially parallel to the lateral members of the holding frame. The rods 21 are movable in a substantially. vertical direction and are pivotally connected with the holding frame at their upper and lower extremities by the levers 17. The arrangement is such that the upward or downward movement of a rod 21 is translated through the levers 17, the ends 18 of which are forced to move in a direction substantially perpendicular to the movement of the rod 21 by means of the slots 18, to a movement of the holding frame substantially perpendicular to the movement of the rod. It will be understood that as the rods 21 are moved up or down the holding frame 12 is correspondingly moved toward the supporting frame or away from the latter. The brackets 13 are provided with guides 22 within which the rods 21 are slidably located.

Near the lower extremities of the lateral members of the supporting frame are brackets 23 at which bell cranks 2,4 are, pivotally mounted. One arm 25 of each bell crank 24 is provided with a fork engaging with an arm 26 extending laterally from each of the rods 21. The other arms of the bell cranks 24 are connected by a hand bar 27 by means of which the bell cranks'may be manually operated to raise or lower the rods2-l.

Whenit is desired to place the screen in position over the window opening, the hand bar 27 is raised, thereby raising the bars 21 and moving the holding frame outwardly from contact with the' supporting frame; the screen is then un olled from \the roll 4 and is -drawn downward until the cross piece 11 rests against the window-sill. The hand bar is then depressed,

. whereby the holding frame is forced against the supporting frame and thus securely clamps the screen in position. The lateral members of'the holding frame do notextend to the window-sill but the arrangement is such that the cross piece 11 engages with the lower extremities of the lateral members of the holding frame whereby the screen is prevented from being accidentally displaced to permit its being rolled upon the roller through the action of the weights 8. It will be understood that when it is desired to remove the screenfrom g i seem? the window it is merely necessary to raise the hand bar of the bell cranks to release the holding frame,

, whereupon the weights 8 slide downwardly upon the guides 10 and return the screen to its inoperative rolled-up position upon the roll 4.

Having thus described my invention I claim as new and desire to secure by Letters Patent 1. A window screen, comprising a supporting frame adapted to iii: in a window, a holding frame adjustable with respect to said supporting frame, a member arranged to slide upon said supporting frame, a lever secured to said member and said holding frame, means for controlling said lever whereby the movement thereof effects a movement of said holding frame, at an angle with the said supporting frame, and a screen adapted to be removahly insertedbetween said frames.

2. A window screen, comprising a supporting frame adapted to fit 'in a window, a holding frame adjustable with respect to said supporting frame, a member arranged to slide upon said supporting frame, a lever secured to said member and to said holding frame, means rigid with said supporting frame for controlling said lever whereby the movement thereof effects a movement of said holding frame at substantially right-angles with said supporting frame, and a screen adapted to be removably inserted be tween said frames.

3. A window screen,v comprising a supporting frame adapted to fit in a window, a holding frame adjustable with respect to said supporting frame, a slidable member carried by said supporting frame, a bracket rigid with said supporting frame, a lever secured to said member and to said holding frame and controlled by said bracket, and a screen adapted to be removably inserted between said frames.

4. A window screen, comprising a supporting frame adapted to fit in a window, a holding frame adjustably mounted upon said supporting frame, said holding frame having three sides and presenting an open side toward the lower portion efsa id supporting. frame, means for forcing said holding frame against said supporting frame, a screen adapted to be removably mounted upon said supporting frame and to be inserted between said frames,

.adaptcd to fit a window.

and a cross plece secured to said screen and adapted to engage with said holding frame at the open side thereof when said screen is in position.

7. A window screen, comprisim. a supporting frame a rod slidably mounted upon said supporting frame, a bracket rigid with said supporting frame and having a slot, a holding frame adjustable with respect to said supporting frame and adapted to be forced thereagainsit. a lever secured to said rod and to said holding frame. and in engagement with said slot of said spring frame bracket, and a screcn adapted to he rcmovnhly inserted between said frames.
