WINDOW-GUARD.

Specification of Letters Patent.

Patented July 3, 1917.

Application filed October 28, 1916. Serial No. 128,164.

To all whom it may concern:

Be it known that I, CHARLES E. PEARSON, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in l/Vindow-Guards, of which the following is a specification.

My invention relates to window guards and particularly to guards which are adapted to be secured to the frame sill and to the sash to follow the sash when opened and to guard the opening against outsiders.

Among the important objects of the invention are to provide improved means whereby the occupant may readily attach the guard to the frame sill and to the sash; to provide improved means for preventmg tampering with or detachment of the securing and locking means; and to provide 1mproved means adapted to be secured to the frame top and to the upper sash to limit the opening distance of the upper sash and to guard the opening after such sash has been lowered.

On the accompanying drawings guard mechanism is shown in which the features of my invention are embodied.

On the drawings Figure 1 is an elevational view of a window frame and sash with my guard mechanisms applied thereto.

Fig. 2 is an enlarged sectional view on plane 2-2, Fig. 1,

Fig. 3 is an enlarged sectional view on plane 3-3, Fig. 1,

Fig. 4 is an enlarged sectional view on plane 44, Fig. 1, and

Fig. 5 is an enlarged sectional view on plane 5-5, Fig. 1.

On the drawing 10 represents the sill and 11 the top of the window frame F, and 12 and 13 represent the upper and lower w1ndow sashes provided with panes 14 and 15.

Thewindow guard for the lower sash comprises upper and lower

horizontal bars

16 and 17 and intermediate horizontal bars 18. The intermediate bars are secured to adja cent inner pivots 19 of lazy tong structures 20. The

lower links

21 and 22 of the outer lazy tong structures are pivoted to. the upper ends of L-shaped latch members 23 whose lower ends 24 are deflected inwardly,

and at intermediate points these latch mem bers are secured to the lower horizontal bar 17 The lower links of the intermediate lazy tong structures are pivoted to pieces 25 which are also secured to the bar 17. The upper links of the lazy tong structures are pivoted to pieces 26 which are secured to the upper horizontal bar 16.

For receiving the ends 24 of the latch members 23 rectangular plates 27 are provided and adapted to be secured to the sill by screws 28. The central sections of the plates are deflected upwardly to form loops 29 for receiving the ends 24, as best shown in Fig. 3. By tilting the guard inwardly the ends 24 can readily be inserted through the loops. The upper'bar 16 has slots 30 at its ends for receiving the horizontal ends of angle pieces 31 secured to the lower window sash. \Vhen thus supported the guard will expand as the lower sash is raised and will guard the opening, and the guard will contract when the sash is lowered. In order to lock the bar 16 to the fittings 31 hasp levers 32 are pivoted to the bar 16 preferably by the same rivets 33 which secure the pieces 26 to the bar. At their outer ends these levers have vertical tongues 34 for engaging through slots 35 provided in the ends of the angle pieces 31, and at their inner ends the levers have slots 36 and 37 respectively for receiving a staple 38 extending from a plate 39, the staple being inserted through the slot 40 in the bar 16 and through the slots 36 and 37 of the levers to receive a pad-lock 41. To release the guard from the sash the padlock is removed and the staple withdrawn, and the latch levers then rotated to withdraw their tongues 34 from the fittings 31., and the bar 16 can be withdrawn from the fittings, and then when the guard is tilted inwardly the ends 24 can be withdrawn from the loops 29 of the sill fittings. To prevent removal of the ends 24 from the loops when the guard is in service, the plates 27 have their outer ends deflected upwardly to form guard walls 42. Also to prevent outsiders from removing the screws 28 and thereby releasing the plates 27, I provide guard plates 4-3 for the fitting plates 27, these guard plates having the central openings 44 for receiving the loops and having ears 45 by means of which they may be secured to the sill by screws 46. When in place these guard plates will cover up the screws 28 of the sill plates 27. The screws 46 could, of course, be removed from the outside but the ends 24 of the guard will still hold the guard plate over the plates 27 to protect the screws 28. The screws 46 are provided merely to dow.

hold the guard plates in place to prevent accidental removal thereof when the guard is removed from the window. WVith the arrangement described the guard can readily be inserted and secured to then follow the movements of the lower sash or can be readily removed, and after being secured it will be impossible for outsiders to enter or to remove the guard. Preferably the fittings 31 are secured to the lower sash sides a distance upwardly from the bottom of the window so that the window sash will prevent an outsider from getting at the screws by which the fittings 31 are secured.

I also provide guard means for any opening left by the lowering of the upper win- As shown, a lazy tongs 47 has its lower links pivoted to a hasp 48 and its upper links pivoted to a plate 49 from which extends the L-shaped latch member 50 for hooking into the loop 51 formed on a plate 52 secured in the groove 53 at the top of the window frame. A tongue 54 extends from the top of the upper sash 13 to be received by the notch 55 in the hasp 4-8, the tongue having the hole 56 for receiving the padlock 57. Preferably, the lazy tongs are of such size as to limit the downward movement of the upper window so that an outsider cannot enter, or, a guard structure similar to that for the lower sash may be provided. In order to prevent an outsider from detaching the plate 52 a guard plate 57 similar to the guard plate 43 may be provided to receive the loop 51 and to cover the screws which hold the plate 52 in place.

As changes and modifications may be made which would still come within the scope of the invention, I do not desire to be limited to the exact construction and arrangement shown, and I claim the follow- 1. The combination with a window frame and a window slidable therein, of a longitudinally eXpansible and contractible guard structure, means for attaching the guard structure to the frame, fittings secured to the sash of the window and having slots, said guard structure being slotted to receive said fittings, hasp levers pivoted to said guard structure and adapted at their outer ends to enter the slots of said fittings in front of the guard structure to thereby lock the guard structure to the fittings, and means for locking said levers in such looking position.
