VENTILATING-CANOPY.

Specification of Letters Patent.

, Patented Nov. so, 1909.

Application filed February 5, 1909. Serial No. 476,262.

To all whom it may concern:

l 3e it known that I, JAMES N. MoonY, a OllilZGIl' of the United States, residing at in the county of Halifax and State of Virginia, have invented certain new and useful Improvements in Ventilatmg-Canopies, of which the following is a specification. I

This invention relates to canopies for beds, particularly adapted for use in the fresh air treatment of tuberculosis and other diseases of the lungsi The present invention embodies an 'ime provement on the device shown in my U. S.

Patent, No. 899,257, datedSept. 22, 1908 and the device shown in my allowed applicatipn, Serial No. v406,211, filed Dec. 12, 190

In the present invention I utilize a canopy for attachment to the inside of a window, so constructed that .the lower sash of the window can be raised a short distance, giving an opening for the admission of fresh air at the bottom, and for the escape of the exhalations at the space between the top part of the lower sash and the lower part of the upper sash. y

In the drawings, Figure 1 is a perspective view of a bed provided with the device and located adjacent a window to which the canopy is attached. Fig. 2 is a vertical sec- .tion through the window and canopy and the head part of the bed.

Referring specifically to the drawings, 6 indicates a canopy adapted to inclose the head of the bed, and in its details it may be similar to that shown in my above-mentioned patent, or otherwise suitably constructed to inclose the head of a sleeper on the bed. The canopy is fixed to a frame 7 which is made the' proper size to fit in the window casing to which it is to be applied, or the frame may be madeadjustable, as disclosed in said patent and application, to

portant and necessary, however, that the height of the frame be greater than that of the lower sash of the window to which it is applied, so that the top bar of the frame, when the latter is set in the window casing, will be located abovethe top bar 8 of the lower sash, even when said sash is slightly raised. The topbar of the frame is also provided, on the side thereof opposite to the canopy, with a flap or piece 9, whlch may be made of fabric of any suitable kind pref-.

It is imerably supported in horizontal position by a small frame 10 of wire or the like. 'The up between the top of the canopy and the upper window sash. For this reason, the

between the top bar of the frame 7 and the contact with fheglass of-the sash.

The bed 11 is placed with its head against the window caslng and inclosed or covered e canopy. The bottom rail of .the-

by th lower sash is also provided with a metal or wooden shield 12 extending outwardly therefrom far enough to cover the outer part of the window sill The pur ose of this shield is to prevent rain or snow eating on the sill and thus entering the window.

. be set in place, as stated lower sash will then be according to circumstances. This will give a passage 13 at the bottom for the entry of fresh air and an outlet 14 between. the sashes, at the top ofthe lower sash, for the escape of expired air. The flap 9 will prevent the impure air flowing up beside the window into'the room. The hei ht of the frame 7 will be such that the said be located sufliciently above the lower sash to allow said sash tobe raised the necessar distance to allow the ventilation desire Inasmuch as the lower sash can .be raised to \{ariousheights, the device can be used uner weather. The fresh air entermg through the space 13 will ass directly to the sleeper or person in the bed and will then flow up and out between the meeting bars of the sashes, as described, thus providinga continuous circulation of air. Obviously in cold or stormy weather the lower sash need only be raised a trifle to produce the necessary ventilation. When t e window is provided with outside blinds the shield 12 may be omitted, as the blinds stormy weather. The invention has the advantage that the lower sash does not have and shown, and the extent, and the interior of the canopy is room under all conditions.

I claim:

In the use of the device, the canopy will,

can be closed in to be opened under all circumstances to full- 1. The combination with a window having upper and lower sashes, of a canopy,
