AUGUST B. PRAETSOH, OF BOSTON, MASSACHUSETTS.
VENTILATOR.
SPECIFICATION forming part of Letters Patent No. 614,497, dated November 22, 1898.
Application filed May 22, 1897. Serial No. 637,698. (No model.)
To all whom it may concer-72,:
Be it known that I, AUGUST B. PRAnrson, of Boston, in the county of Suffolk and State of Massachusetts, have invented an Improvement in Ventilators, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.
This invention relates to ventilators, and has for its object the production of a Ventilator of simple and compact construction particularly adapted for insertion in windowsashes or in doors and the like.
The various features of my invention will be hereinafter fully illustrated and described in the drawings and specification and set forth in the claims.
Figure l shows a ventilator of my improved construction applied to the lower bar of a window-sash, indicated in dotted lines. Fig. 2 is a plan View of the ventilator with the inner face-plate removed to reveal the interior construction of the ventilator. Fig. 3 is a transverse section on the line Fig. 2.
In the preferred embodiment of my invention selected for description and illustrated in the drawings, A is a casing of suitable material, preferably cast metal, rectangular in shape and substantially equal in depth to the sash or other partition B in which it is to be placed, such partition being previously apertured or prepared, as at b, to receive the Casing snugly.
In the form illustrated the casing is provided with an integral iiange a', surrounding and projecting laterally from the body a at the rear edge and having a slot a2 nearly equal in area to the central cavity of the casing and covered throughout by a piece of gauze as, suitably secured to the casin-g.
The casing havingr been inserted in the aperture b from the outside as far as will be permitted by the flange, (if the latter be integrah) an entrance for a continuous supply of fresh air is afforded, while dust, insects, or other extraneous matter will be excluded by the gauze screen.
To further insure the purity of the air-supply, I have provided an extra screen c for the inner side of the Ventilating-passage, and in order that this inner screen may be readily fixed in position or removed I have shown it as mounted on an apertured plate C, preferably symmetrical with respect to the iiange a', but separate from the casing.
By making the screen removable I afford means to gain ready access to the interior of the casing to clean out any dust which may make its way through the outer screen, and to promote this facility of removal a convenL ient means of connecting the screen-plate to the casing will be found in headed screwbolts d, inserted into holes in the screenplates, through which and the sash they pass to engage and coperate with the threaded walls of holes a4 opposite in the iiange a.
The effective aperture of the ventilator may be varied by a longitudinal damper E, carried within the casing on a spindle e, on the projecting end e of which a regulating-sector e2 is mounted, extending into a slot c2 of the screen-plate in position to be engaged by the inger.
A spring e3, interposed between sector and casing, serves to hold the damper in adjusted position.
Having thus fully described my invention, I do not limit myself to the exact construction shown, inasmuch as the same may be varied considerably Without departing from the spirit and scope of my invention.
Having fully described my invention, what I claim, and desire to secure by Letters Patent, is
l. The combination with a window-sash or the like, having a body-aperture for ventilating purposes, of a casing seated in said aperture and having at one side a gauzescreened opening and a flange extended beyond the Walls of the casing; a damper mounted rotatably within said casing upon a spindle; means extended through one end wall of said casing, and provided with a sector, by which to operate said damper; a separate closure for the side of said casing op posite said iiange, said closure having a ventilating-opening provided with a gauze screen, Y
