'VENTILATING DEVICE.

Specification of Letters Patent.

Patented Jan. 21, 1908.

Application filed August 9. 1907. Serial No. 387.772.

To all whom it may concern:

.Be it known that I, LESLIE S. HACKNEY, of St. Paul, Ramsey county, Minnesota, have invented certain new and useful Improvements in Ventilating Devices, of which the following is a specification.

My inventionrelates to a ventilating apparatus and the object of the invention is to .provide means capable of quick and'easy attachment to a window for the purpose of supplying fresh air to the room and removing the foul air therefrom.

A further object is to provide an appara tus, that is particularly adapted for sick rooms and movable from one room to another when used in a hospital to supply fresh air to the patient and remove the impure air around the bed. v r

The invention consists generally in various constructions and combinations, all as hereinventionto a window, and the manner of conducting the fresh air to the bed and removing the impure air therefrom. Fig. 2 is a detail view. illustrating the adjustable feature of the board on which the apparatus is mounted, to adapt it for windows of different width. Fig. 3 is a detail view illustrating the outside of the board. Fig. 4 is a sectronal view illustrating the intake and outlet pipes permanently inserted in the outer wall of the building. Fig. 5 is a detail sectional v ew lllustrating the position of the intake pipes and a cap for closing the same.

n the drawing, 2 represents the wall of the room, 3 the window sash, 4. a shelf adapted to rest on the sill 5, and 6 a plate adapted-to fit between the sill and the sash and having a movable extension 7 at one end adjustably connected with the part 6 through a slot '8 and thumb screw 9 to allow the board to be fitted into windows of different widths. 10 is a suction fan having a pipe 11 extending through the board 6 and upwardly therefrom to a oint near the bottom of the upper sash and aving an open outer end through which I the impure air drawn from the room by the operation ofthe fan is discharged.

A tube 12 is connected to the fan 10 and has a funnel 13 at its opposite end which, as shown in Fig. 1, depends to a point near the floor, a suflicient suction being created by the revolution of the fan to withdraw all the foul or impure air which collects in the lower part of the room. The tube 12 may be made of any suitable length to permit the funnel to be placed in any part of the'room or under or in the bed if desired.

I prefer to provide a fresh air tube 14 having a funnel 15 at its inner end and fitting, within an opening 16 in the extension 7, over which a gauze screen 17 is placed. This tube 14 may be hung over the head of the bed where the fresh air can be delivered to the patient and whenever desired the tube and funnel can be moved to other points in or on the bed or to other parts of the room.

The funnel may be held in the hand and the fresh air inhaled.

, It is extremely diflicult to ventilate a sick a window where the draft will blow directly upon the sick person. It has also been found very difficult to properly ventilate bed clothing without danger of exposing the patient to cold or drafts. With this apparatus it will be unnecessary to move the erson in the bed, the fresh air tube being p aced in any desired position in the room or on the bed and the impure air funnel being adjusted wherever it is desired to create the circulation and change the air.v In hot weather this apparatus will be found very useful as the circulation can, be maintained through the bed and the impure air entirely removed from the room.

I prefer to employ an electric motor 18 for driving the fan, also mounted on the board 6 and capable of movement therewith from place to place and adapted to be driven by the electric'light current which may be delivered thereto through the conductor 19 that is plugged into the light 20 in the usual way.

Instead of having the intake and exhaust tubes mounted in a board that is capable of adjustment in a window, these tubes may be connected with fresh air and foul air pipes permanently arranged in the building wall. The operation of the apparatus, .however, would be substantially the same. The use of the board renders the device capable of and outlet pipes that are permanently 31-.

ranged in the wall of the building. 21 represents the intake pipe arranged in the building wall above the'window and having an inner-end on which the tube 14 is adapted to be fitted. A removable cap 22-is provided for closing the inner end of the pipe when the device is not in use.

For taking out the foul air I prefer to provide a flue 23 mounted on the outside of the wall 'of the building and extending up to a point near the roof. The lower end of the ipe 23 is extended inwardly through. the base board and the foul air tube may be fitted over this inner end, or in some instances the tube may be omitted and the foul air allowed to pass directly into the open end of the flue. Considerable suction will be created in the flue 23 and the foul air accumulating in the lower part of the room will pass off therethroug I have shown this ventilating device in connection with a bedroom but do'not wish to confine 'myself to such use as his well adapted for ventilating purposes in living and other rooms of residences, hotels, or other buildings and in the compartments. or staterooms of cars and steamshipa.

I claim as my invention:

1. A ventilatin a paratus comprising a board adapted toe tted into a window between the lower sash and sill, a suction fan having a pipe extending through said board to the open air, said fan being attached to said board and movable therewith from place to place, an .electric motor also attached to said board and connected with-said fan, a flexible tube connected with said fan and having a funnel at its free end adapted to be inserted in or under a bed, and a second flexible tube extending through said board to the open air and having a discharge'funnel at its free end, substantially as described.

2. The combination, with a board, having an adjustable extension to adapt it for windows of different width, and capable of fitting between the lower sash of the window and the sill, a suction fan having a pipe extending through said board to the open air, a flexible place, and a fresh air tube connected with'an' opening in said board and having a funnel at its free end and through which fresh air is delivered into the room, substantially as described.

3. The combination, with a board comosed of adjustable sections and adapted to be fitted to windows of different Width between the lower sash and the sill, an impure air pipe extending through said boardand upwardly to a point near the top of the sash,

a flexible tube connected with said pipe, and V a second flexible tube extending lnto an opening in said board and communicating therethrough with the outside air, substantially as described.

' 4. A ventilating apparatus comprising pipes arranged to extend through an outer wall and having open outer ends communicating with the atmosphere and tubes adapted to be fitted on the inner ends of said pipes and having funnels, one of said tubes serving as a fresh air inlet and the other tube as an exhaust for the foul air, substantially as described. l

5. A ventilating apparatus comprising pipes arranged to extend through an outer ,wall and having open outer ends commun1- eating with the atmosphere and tubes adaptedto be connected to the inner'ends of sa d pipes, one of said tubes serving as a fresh all in foul air, both of said tubes having their inner ends exposed to the atmosphere and capable of being moved from place to place, where the ventilation of the space may be regulfi substantially as descrlbed.

In witness whereof, I have-hereunto set my hand this 29th day of July, 1 0
