lUT 1i WINDOW SCREEN AND SASI-I LOCKER.

Specification of Letters Patent.

Patented Aug. 29, 1916.

Application filed September 10, 1915. Serial No. 49,930.

To all whom it may concern:

Be it known that I, CLAUDE ELLIS, of Springville, Erie county, New York, United States of America, have invented a Window Screen and Sash Locker.

This invention relates to window sash and screen looks or fasteners, and is for the purpose of locking the lower window sash of an ordinary window firmly to the ordinary window screen of commerce, and also at the same time locking the upper window sash firmly to its casing. This device is also for the purpose of locking an upper window sash firmly on to the ordinary screen of commerce when put in the upper window space and at the same time firmly locking the lower sash to its casing. When used in either window space the device prevents the raising and lowering of both windows while the screen is in place and also serves to lock the window screen to the window casing.

The device is portable and can be readily and very quickly applied to a window or detached therefrom without scarring or in juring the woodwork in any way.

In the accompanying drawings: Figure 1 is a perspective View of a window provided with a sash and screen look constructed in accordance with this invention, the screen being placed beneath the partially raised lower sash and the screen locked in position. Fig. 2 is a. sectional View of the locking device.

1 represents an ordinary window having sliding upper and lower sashes 2 and 3, provided with window panes 4 in the usual manner. The lower sash is raised to admit a wire screen which is placed in position beneath the lower sash with its ends extending into the sash guide-ways in the casing. These parts may all be of any ordinary and well known construction.

Referring to Fig. 1, 5 represents the window sash and screen locking device. It cohsists primarily of two blocks of wood, or other suitable substance, 6 and 7, preferably rectangular in shape, although they may be of any other convenient shape. Referring to Fig. 2, block 7 has 2 holes 8 and 9 respectively. These holes are for bolts and are so constructed as to fit tightly aroundthe shoulder of the bolts employed, which are designated 10 and 11. Block 7 has also a rectangular slot 12 piercing the block near its upper end. This slot, on the outside of the block, is as wide as the head of the bolt 13. This width preferably continues to a depth equal the thickness of the bolt 13, when the slot abruptly assumes a width equal to the diameter of the shank of the bolt so that when the bolt 13 is inserted in the slot its head will be flush with the outside surface of the rectangular block 7. The rectangular block 7 has a cylindrical groove in its end, the diameter of which is suflicient to admit the largest part of the plug represented herein at 14 with a coil spring 15 assembled on the small end of same. The cylindrical groove in the end of block 7 abruptly assumes a smaller diameter at its lower extremity, of a width sufficient to admit of the smaller diametered portion of the plug 14, the shape of which cavity is indicated in Fig. 2. A hole pierces the rectangular block 7 near its top, piercing the large cylindrical chamber to admit of the pin 16. Plug 14 is pierced by a rectangular slot the same distance from the end of the plug 14 as the pinhole of pin 16 is from the end of the block 7. The slot piercing the plug is as long on the side of the plug as the distance between the hole piercing the end of the rectangular block 7 and the end of the rectangular block 7, and the plug, cavity, spring and pin are all so spaced and arranged that when the plug, spring and pin are assembled in the block the plug may be pressed into the hole in the end of the rectangular block so that its end is flush with the end of the rectangular block 7. Pin 16 is long enough to pierce the end of block 7, as in Fig. 2.

10 represents a bolt afliXed permanently to block 7 and just long enough to pierce block 7 and the rectangular block 6 and is unthreaded. Bolt 11 is unthreaded near its head and the unthreaded portion is slightly less in length than the thickness of the rectangular block 7. It is threaded on its end so as to engage the threads of the thumb screw 17. Bolt 13 is threaded almost to its head, so that it may be adjusted firmly in any position in the slot 12 by means of the thumb screw 18.

19 represents a sleeve, the inside of which is so threaded as to engage the threads of bolt 13. This sleeve with bolt 13 and the thumb nut 18 form a means adjustable vertically up and down the block 7 for catching the under side of the upper rail of a window sashand locking the same against the casing of the window, and is adjustable laterally to adapt same to various widths of window casings. Bolt 13 may be used without sleeve 19 for such purpose and may be covered with rubber or other suitable substance to prevent marring the sash, although sleeve 19 gives a greater range of adaptability than the bolt13 alone would offer. Sleeve 19 may be covered with rubber if desired, to prevent marring the window sash.

Rectangular block 6 possesses a slot represented by 20 in Fig. 1, piercing the block and running lengthwise of the block and nearly from one end of the same .to the other. The width of thisslot is just sufficient to easily pass the shanks of bolts 10 and 11, which shanks are both of equal diameter. Blocks 6 and 7 are fastened together by means of bolts 10 and 11, passing through the long slot in 6, bolt 10 serving 'merely as a guide and bolt 11 and thumb just clears the glass of the window. Loosen the thumb nut between the sleeve and the block on the upper member of the device and adjust the bolt so that the sleeve nicely catches the under side of the top of the window sash, and tighten-the thumb nut so as to lock same.

If it is desired to use the fastener with the upper window sash lowered and a screen in place in the upper window space, the device is placed in position so that its lower extremity rests on top of the lower sash and the adjustable locking member is directly underneath and in contact with the bottom face of the top rail of the upper sash. Proper'adjustment is secured by means of the thumb nut.

I claim as my invention:

1. The combination in a window screen and sash locker of two barlike members, one with a spring and plug at its end adapted to engage the casing of the window, the other adapted at its lower end to engage the top of the window sash, with means for fastening the two broadest surfaces of the two members together at any given point, means for keeping the two members in alinement, with means mounted on the member with the spring and plug for locking the upper window sash.

2. The combination in a window screen and sash locker of two barlike members, one with a spring and plug at its end adapted to engage the casing of a window, the other adapted at its lower end to engage the top of the window sash, with means for fastening the two broadest surfaces of the two members together at any given point, means for keeping the two members in alinement with adjustable means adjustably mounted on the member with the spring and plug for locking the upper window sash.

3. The combination in a window screen and sash fastener of two barlike members, one with a plug and spring at its end adapted to engage the casing of a window, the other adapted at its lower end to engage the top of a window sash, means for fastening the two bars together at any desired adj ustment consisting of two bolts permanently aflixed to the lower end of the member with the spring andplug, the shanks of both bolts passing through the other bar by means of a rectangular slot piercing the other bar and running nearly from one end of the bar to the other, one bolt serving merely as a guide, the other bolt with threads and a thumb screw adapted to engage the threads and serving to lock the two bar members together, adjustable locking means for the upper window sash adjustably mounted upon the upper bar member,and adapted to engage and lock the upper window sash.

CLAUDE ELLIS.
