SPECIFICATION forming part of Letters Patent No. 280,092, dated June 26, 1883.

Application filed December 28, 1882.

To all whom it may concern.-

Be it known that I, FRANK R. SIL'rZ, of Leon, in the county of Decatur and State of Iowa, have invented a new and Improved Ventilator, of which the following is a full,

clear, and exact description.

The object of my invention is to provide a new and improved ventilator adapted to be secured in doors, windows, &c.

The invention consists in a ventilator formed of a barrel containing a'wind wheel, and provided at one end with a wire-netting, and at the other end with a hinged cap, which can be thrown open by a spring attached to the barrel, which cap is provided with a series of openings which can be closed by a plate held on the inner surface of the cap, and provided with a spindle and pawl for'turning it, whereby, by opening the apertures in thecap or by opening the cap, more or less air, as desired, can be admitted into the room through the ventilator.

Reference is to be had to the accompanying drawings, forming part of this specification, in

which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is an inside elevation of my improved ventilator, showing the manner in which it is secured in a sash. Fig. 2 is a sec- 0 tional elevation of the same on the line a: m,

Fig. 1. Fig. 3 is an inside elevation of a modification of the same, the hinged cap being shown opened. Fig. 4 is an outside elevation of the same.

A barrel or cylindrical casing, A, is secured in a plate, B, or ring B, so that it projects from one or both surfaces of the same, which barrel is provided with two transverse bars or strips, 0, in which a shaft or rod, 0, is jour- 40 naled, 011 which is rigidly mounted aven'tilator-wheel or winged wheel, D, of the usual construction. The said wheel D can revolve freely in the barrel A. A wire screen, E, is secured on the outer end of the barrel A, to

4 5 prevent insects, dust, &c., from passing through the ventilator into the room. To the inner end of the barrel a cap, F, is hinged, which is (No model.)

provided with one or more apertures, G, either circular, wedge-shaped, or of any other suitable shape. A plate, H, resting against the inner surface of the cap F, is provided with apertures I in the same manner as the cap, and is provided with a central spindle, J, passing through the-cap F, and provided on its outer end with a knob or button, K. If desired, the

apertured plate H can be replaced by a small plate, II, provided with wings I, adapted to close the apertures G. A spring, L, secured to the barrel A, rests against the inner surface of the cap and throws the same open as soonas the same is unlocked or released. The plate B is passed into one corner of a sashpane, M, which has been cut out correspomlingly, and the edge of the plate B is bent over the edge of the pane M; or the ring B can be fastened to a door, &c. If the cap F is closed, and the plate H closes the openings G in the cap, no air can pass through the ventilator. If the plate H is so turned by means of the button K that' the openings G will be openthat is, coincide with the openings I or if the wings I do not cover the openings G, air can pass through the ventilator. If .the cap F is released or unlocked, the spring L willthrow it open and a greater quantity of air can pass through the ventilator.

The said ventilator supplies any room with avery large quantity of fresh air, and the ventilator can easily be adjusted to admit any de sired quantity of air. One or more ventilators can be fastened to any door or window.

The ventilator will be manufactured from sheet tin or iron, granite-iron, or any kind of metal.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. In a ventilator, the combinatioinwith the barrel A, having the wind-wheel l) and the wire netting, of the hinged cap F and the spring L, substantially as and for the purpose set forth.

2. In. a ventilator, the combination,with the barrel A, of the wind-wheel D, the hinged cap z eeaoee E, and the spring L, substantially as herein 1 shown and described, and for the purpose set forth.

3. In a ventilator, the OOlllbilliLtiOll,\\'it1l the narrel A, of the Wind-wheel. D, the cap F, provided with apertures G, a plate held on the inner surface of the cap and adapted to close the openings in. the cap the spindle J, at

taehed to the said plate and passing through the cap, and the knob or button K 011 the spin- 10 die J, substantially as herein shown and described, and for the purpose set forth.
