VENTILATOR.

Specification of Letters Patent.

Patented June 11, 1907.

Application filed September l, 1906- Serial No. 332,927.

To a/ZZ whom it may concern,.-

Be it known that I, EVA STEVICK, a citizen of the United States, residing at Grover IIill, in the county of Paulding and State of Ohio, have invented new and useful Improvements in Ventilators, of which the following is a specification. l i

This invention relates to ventilators and it has for its object to provide a ventilator' which may be conveniently mounted in position for operation which shall be adapted to be fitted upon walls of different' thicknesses; which may be conveniently manipulated to regulate the ventilation; and the interior of which shall be conveniently accessible for cleaning purposes.

Other objects of the invention are to simplify and improve the construction and operation of this Class of devices.

lVith these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention; it being however, understood that no limitation is necessarily made to the precise constructural details therein exhibited, but that changes, alterations and modifications within the scope of the invention may be resorted to when desired.

In the drawings: Figure 1 is a longitudinal sectional view of a ventilator embodying the invention. Fig. `2 is an end elevation showing the inner end of' the ventilator. Fig. 3 is an end view showing the outer end of the ventilator. Fig. 4 is a sectional view taken on the plane indicated by the line 4-4 in Fig. 1.

spring catch 9 which may be struck from the flange 3 of the sleeve 1, will serve to retain the lid 5 in a closed position.

The damper 6 is provided with a suitable ring or link 10 to which are attached operating cords or flexible members 11, said cords being guided through links or eyes 12 that are connected with the vflange 3. By means of these cords, the damper may be adjusted to various positions, for the purpose of regulating the ventilation.

The flange 10 of the sleeve 2 is protected by a foraminous covering, such as a piece 13 of wire netting, which may be secured by means of lugs 14 struck from the flange 4; dirt and insects will thus be excluded from the ventilator. In order to exclude rain, the flanged end of the sleeve 2 is guarded by means of an overhanging cap or hood 15 having a vflange 16 fitting against the inner side of the flange 4, as will be clearly seen in Fig. 1 ofthe drawings.

To mount the improved ventilator in position, a hole of suitable size is cut in the wall of the room or building where it is to be applied. The sleeves 1, 2 are then separated and inserted from the opposite ends of the hole or aperture, being assembled within the latter and telescoped together until the flanges 3, 4 abut upon opposite sides of the wall. The hood or cap 15 is then placed in position, and the parts may then be secured by nailing through the flanges 3, 4. Ventilation may be regulated by means of the damper 6, or by entirely opening the lid 5 which also affords access to the interior of the ventilator for the purpose of occasionally cleaning the latter.

The improved ventilator is simple, inexpensive and sanitary, and it may be easily and quickly installed in position for operation.

Having thus described the invention what is claimed is:

The herein described ventilator comprising a pair of sleeves, each having an annular flange at one end thereof, and one of said sleeves having a stormY hood projecting outward from the top of its flange, and said sleeves being mounted to telescope one within the other, a damper at the inner end of said ventilator, a hinged lid to which the damper is pivoted, said lid having radial openings therein, a spring clamp cut from IOO the flange of one of the sleeves for holding said lid in closed position7 said damper being mounted to rotate on a central pivot which attaches said damper and lid together, and said damper provided With openings, a screen secured to the outer end of the ventilator by lugs out from the flange of one of the sleeves and bent over the screen material, a, ring eonnected to the lower edge of the damper, rings connected to the rigid flange, and cords lead- 1o ing through said rings for rotating said damper.

In testimony whereof, I aHiX my signature in presence of two Witnesses.

EVA STEVICK. Witnesses:

S. C. STEVICK, H. GOTTSHALL.
