ALFRED CREIGH srEvENsoN, or OAK'DALE STATION, PENNSYLVANIA,

MEDICTED'VENTILATOR.

SPECIFICATION forming par@ 'of Letters Patent No.l $49,405, dated November-"5, 119.95.|

Application filed January 9, 1895.

To all whom itmay concern: Y vBeit known that L ALFRED GREIGH Sra vented a new and Improved Medicated Ventilator, of which the following is a full, clear;

and exact description.

`My invention relates to' improvements in and the object of my'invention is to produce tilator which may be applied to any ordinary germs from being carried into the roognfwhich may be used merely to supply pure air, if de-v sired, Which is also adapted' to provide air laden with suitable antiseptics or disinfectadmit the fir Without an'objectionable draft, and which in general is adapted to form a sub- The invention is also intended to provide an outlet for impureor overheated air.

' To these ends my invention consists of certain features of construction and combina'- scribed and claimed. y

Reference is tobe hadto the accompanying drawings, forming a part of this specification,

correspondingparts in all the vieufs. l

Figure -1- is a front elevation of my iinproved ventilator as applied to anvindow.

Fig. l. Fig. 3 is a sectional plan on the line view of the main perforated lbox of the ventilator. Fig. 5 is a detail perspective view ends and of the cleat to which the socket is of the cleats adapted to carry a box-socket, and Fig.y 7 is a vieW of the angle-clip or bracket forming an adjustable bottom to the said socket.

The ventilator 1s provided With a boX 10,

long enough to4 extendacross an ordinary Window, and the box is preferably made up ,serai No. 534,309.l @To man.)

devices, and, if desired, the ends of the box may be sealed airtight With rubber ,or anything suitable for the purpose. i

Wit-hin the box is heid a Screeniawhichl is Wide enough to extend from top'to bottom of the` box, preferably at a slight incline, as

shown in Fig. 2, and this-screen is made, by

held over a stiffening-frame 13a. (See Fig. The screen may be of any suitable material and shouldbe line enough vto prevent.` dust from passing through the' ventilator. When de s'irethaf suitable medicament or antiseptic may befplaced in the box, and the vapor rising from vthe vsaid'medicam'C-rnt or antiseptic mingles With the atmospheric air and passes into the room through the holes 12.

To provide Nfor the easy insertion of the antiseptic or medicament the box is provided on its inner side with an opening 14, Which has a sliding door 15, by which it may be closed.

The box ends are held in sockets 16, which .are of a general U shape in cross-section and preference, in the form of a bag, so as to be bent inward at the'top to forma flange 17,

which overlaps the top of the box 10 when the latter is held in the socket. is secured to a cleat 18, Which is adapted to be secured in the runway of the Window-frame and which is provided with a groove 19 to receive the sash-cord. The socket `has an adjustable bottom formed of an angle-iron or bracket 20, which has in itsback a vertical slot 2l to enable it to be adjusted on the fas tening-boltQZ, by which it is secured to -the cleat 18. The bracket 20 serves as a support for thebox 10, and italso serves as an abutment for the Window-sash and prevents the sash when it is raised fronr striking with damaging effect against the box.

. To apply the device to a Window, the cleats 1S are fastened in -the top of the Windowframe, at the upper end of the runways 23 of IOO - 1.3into the room.

the inner sash 24, the box is placed ini the sockets, the upper sash dropped simi-- 'ciently to permit the air to pass throughathe box, and the air will then pass through fthe perforations of the box and through the sieve If no medicament is used, the pure'air enters 'the room, and if the medi, ciment is used the vapor of the medicament mingles with and impreguates the air, so that it passes into the' room in a condition to be inhaled.

It will of course beunderstood that the ventilator may be arranged in the runway of either sash and even at the bottom oi the 15. window instead of at the top without departing from the principle 'of the invention, and it will also be seen that the construction of the box and its supports maybe departed from somewhat Without aiecting the invention.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A window Ventilatoncomprising a per- 'forated box, and cleats adapted to support the end s of the box and provided with grooves for the reception of the sash cord, substantially as described.

2. .A ventilator, comprising a perforated I box, end sockets to support the same, an'd` adjustable bottoms for the sockets, substantilly as described.

3. A ventilator comprising a perforated box, sockets to receive the ends of the same, said sockets being open at their lower ends, and separate bottoms projecting inwardly at the open ends of the sockets to support the v ends'of the box, saidbottoms being removably connected tothe sockets, substantially as described. Y

4. A ventilator, comprising a perforated box formed of separable half sections, a screen heldwithin the box, end sockets to receive the box, adjustable bottoms for the said sockets, and means for securing the sockets yin the frame of a window, substantially as ALFRED CREIGH sTEvENsoN.
