UNITED STATES PATENT OFFICE.

VVENTILATOR.

Specification of Letters Patent.

Patented me 4, 1907.

Application filed December 29, 1904. Serial No. 238.701.

T aZZ whom it ntcty concern.-

Be it known that I, JosEPn A. HIOKEY, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Ventilators, of which the following is a specification.

This invention relates to ventilators, my object being to provide in this connection-Ya simple, inexpensive and efficient construction and organization of parts.

IVith this object in view the invention consists in the novel constructionand combination of parts which will be hereinafter fully described and claimed.

In the drawings :Figure 1 is a perspective view of the lower portion of a window having my improved ventilator applied thereto. Fig. 2 is a sectional view, as on the line 22 of Fig. 1. Fig. 3 is a perspective view of the drum for regulating the air. Fig. 4 is a vertical section through one end of the ventilator, as on the line 44 of Fig. 2.

1 designates a portion of a window frame and 3 the sash therefor. The sash is fitted to lateral guideways 5 in the frame 1 whereby the sash 3 may be raised and lowered, as is well known.

My invention in its preferred embodiment is of the following construction 6 designates a casing comprising the inner and outer

vertical walls

7 and 8, respectively, the upper and

lower walls

9 and 10, respectively, and the end walls 11. This casing 6 is adapted to be placed between the bottom of the window sash and the win-- dow frame and to rest upon a horizontal bar 12 of the frame, the bar 12 being located inwardly of the sash. The upper wall 9 is provided with an inset angular portion 13 adapted to receive a corner of the sash 3, and the lower wall is provided with an inset angular portion 14 adapted to receive a corner of the rail 12. Thus it will be seen that the casing 6 extends into the room to be ventilated and also into the space between the bottom of the sash and the window frame, and that when the casing is placed in the position shown, it is maintained therein by the engagement of the corners of the sash 3 and rail 12 with the

inset portions

13 and 14, respectively.

Slidingly fitted to the ends of the casing 6 to conform to the cross section thereof, are telescopic end extension members 15 which may be moved toward and from each other to adjust the length of the ventilator to properly fit the width of the window. These extension members 15 are provided with other extension members or projections 16 which are adapted to enter the vertical guideways 5 and, taking against the side walls thereof, still further assist in holding the ventilator in place.

The outer vertical wall 8 of the casing is provided with a series of inlet openings 17 to admit air to the casing, and upper wall 9 is provided with a substantially horizontally arranged, elongated outlet opening 18 through which the air passes into the room to be ventilated.

Extending longitudinally through the upper portion of the casing 6 and journaled in the end walls 11 thereof is a partially rotatable drum 19 directly below the opening 18, the upper wall 9 of the casing being curved to fit the drum. The drum 19 is provided with a series of large openings 20 extending over a portion of its surface, a series of perforations 21 extending over another portion of its surface and a plain portion 22 having no openings therein. The openings 20 are adapted to permit the air to pass from the casing 6 to the interior of the drum 19, and the perforations 21, when brought into register with the opening 18 are adapted to permit the air to pass from the drum into the room to be ventilated. The drum 19 is provided with a suitable handle or knob 23 as a means whereby the drum may be adjusted to bring any number of the perforations 21 into register with the opening 18 and thereby regulate the admission of air to the room, or to bring the plain portion 22 of the drum into register with the opening 18 and thereby close the ventilator, or permit no air to pass into the room.

' The lower wall 10 or bottom of thecasing 6 is provided with openings 24 to permit any water that may enter the casing 6 to drain out. v

While I have herein shown and described my invention in a desirable and practicable form yet I do not limit myself to this particular construction as the same may be modified without departing from the invention.

I claim 1. In a device of the class described, the combination with a casing having vertical inner and outer walls, the latter having an inlet for the air, said casing also having its upper portion open for the discharge of the LOO ITO

air, and provided in said upper portion with an inset'angular portion adapted to receive a corner of a sash, the lower wall of the casing being also provided with an inset angular portion to receive a portion of the window frame, said inset portions serving to maintain the casing in position, of a drum journaled in the upper portion of said casing, said drum having a series of perforations adjacent to the discharge opening of the casing to be moved into and out of register with said opening, whereby the discharge of the air from the casing is regulated, said drum being also provided at a point substantially opposite to said perforations with an opening for the passage of the air into said drum, and having an imperforate portion midway the perforations and said opening.

2. In a device of the olass described, the combination with acasing having vertical inner and outer walls, the latter having an inlet for the air, said casing also having its upper portion open for the discharge of the air, and provided in said upper portion with an inset angular portion adapted to receive a corner of a sash, the lower wall of the casing being also provided with I an inset angular portion to receive a portion of the window frame, said inset portions serving to maintain the casing in position, of a drum j ournaled in the upper portion of said casing, said drum having a series of perforations adjacent to the discharge opening of the casing to be moved into and out of register with said opening, whereby the discharge of the air from the casing is regulated, said drum being also provided at a point substantially opposite to said perforations with an opening for the passage of the air into said drum, and having an imperforate portion midway the perforations and said opening, and an extension member telescopically mounted upon the end of said casing for adapting the ventilator to windows of varying widths.

In testimony whereof I afiix my signature I in presence of two witnesses.
