Tool! whom it 'nmy concern: 7

Be it known that 1, Scenes MAINE, oi Boston, in the county of Suffolk and Gournionwoalt-h of lliassachnsetts, have invented: a new and Improved Ventilato and I here by declare that the lollow'ing is a full, clear, and exact description. thereof, reference bein g had to the accompanying drawing and to the letters of reference marked thereon.

My invention has for its object to provide :ior apartments oi. every kind a means of You tilation. that shall be simple and economical in its construction, and, at the same time, eliicient in its operation; and its principal feature consists in so constructing the ventilator that the currents of fresh. air will be deflected from a direct course on entering the a 'iartinent to he ventilated, and thrown in substantially a vertical direction, so as to impinge upon the coilin g of the room above the ventilator. it also consists in proriding the ventilator with an adjustable irarnc, by means of which it may be fitted to anywindow in which it may be desired to use it.

I also propose, when desired, to provide my lent receptacle for COIlla-lllllQ a disinfectant or an 37 other substance 'ith which it ill? be desired to impregnate the ilL it passes in through the ventilator, though I. am aware that this, in itself considered, is not novel.

For the purpose 'oli' dcl'lecting the currents of air from their direct course, I make use of same being turned substantially at right, angles to each other-one arm of this elbow being inserted in the orifice that eonnnuni cater between the apartment and the air outside, and, being" cylindrical in form, it can readily be turned in its frame or setting and adjusted at any required angle, so that the inner end of the pipe may be directed up ward toward the ceiling, ordowm 'ard toward. the lloor, or toward any other desired point. For the ordinary purposes of ventilation, it will be made to occupy a vertical position, being turned directly upward. When it is turned in this direction, the cool air, it is introduced, is pro'cctcd upon the ceiling, being there dili'nsed radially over the entire room,

and gradually settling down from its own gravity, and mingling with ttliei vitiated air equally in all parts of the apartment. If ,oIrned downward, the air will first be brought in contact; with the floor, spreading itself out over the entire surface, and gadually rising it becomes expanded under the higher tem perature of the apartment.

It will readily be seen that the great advantage of the mode of ventilation consists in the fact that, while an abundant supply of fresh air is at all times iusuredjto the occupants of the room, yet thcy are entirely free from the injurious etl'ects arising from exposure to either the direct or indirect drafts ior current-sthat characterize other systemsof ventilation in which there is direct communicat-ion through the windowsor wailsof-an apartment with the external air. Aperson may sit close to one of my improved ventilators, when a strong current of air ispassiug in through it, and the air of the room is being rapidly changed, without feeling'the:slightest draft. r 4. i

I am aware that it is no uewinventiou to change the direction of the currents of air on entering an apartment to be ventilated. This has been done by the use of a screen or shield placed directly in front of the opening which coninninicates with the external air; but such appliances have been intended simply to pro tect the person sitting in front of them from the direct draft, and they have not, to my knowledge, been so constructed as to throw the entire body of fresh air admitted, in an unbroken ccliunn, upward in a vertical diroction. Being nnincased at the ends, and some tizncs at the bottom, they would permit the air to tlow out laterally and downward as well as in an upward direction, and, for this reason, would be but poorly adapted for apartments used for public assemblies.

I am also aware that ventilators has'o been used which give the air an inclined upward direction. The radical difference between such devices and my invention-consists in the fact that all such ventilators throw the column of air upon the ceiling at; sucli an angle that it is rellceted therefrom and dcscends upon the heads of the persons occupying the room. My ventilator, on the other hand, causes the column of air to impinge. upon the ceiling in such a way that itis immediately broken and dispersed, mingling with the air of the room near the ceiling, and gradually settling down of its own gravity. For the purpose of regulating the flow of air through the ventilating-tube, I place a damper in one armof it 'so constructed that it may entirely close the passage or open it to its fullest capacity, or occupy any intermediate position.

In adapting my ventilator to ordinary housewindows I usually prefer to employ two tubes or elbows; and, that the ventilator may be see viceable'in windows of dilferent widths, I cone st-ruct the frame of two sections of the requisite width,to beplaced beneath the raised sash,

. inserting one tube in each section; and these -dinary window.

- halt' an-inch thick.

sections Imake ad'ustable by means of hinges, slides, or in any lil re manner, so as to admit of their being extended, folded, or contracted so as accurately to fill the space between the two sides of the window frame. A convenient method of effecting this adjustability is to seend of my ventilatontube the metal may be indented or depressed so as to Form a cup for receiving any disinfectant or other substance with which it'is sought to impregnate the air of the room. By turning the tube down into a'horizontal position this cup will be brought into aposition'to hold liquids. 'lhe disinfectant or deodorizer is now placed in the cup, and, by opening the damper and admitting a current of air to pass over the cup, the liquid is evap- On one side of the inner orated. and the vapor distributed to all parts of the room. To hasten evaporation and to prevent spilling of the liquid a sponge may be placed in the cup. Instead of a cup formed in the sid of the tube, as above described, a small pan 'nay be used, which is to be placed in the tube and removed at pleasure, or the cup may be attachedto the outside of the tube.

Referring to the accompanying drawing, in which there is shown'a perspective view of the entire apparatus constituting one oi. my portable and adjustable window-ventilators, A and a are the two sections of the frame. B and b are the elasps between which the sections are held so as to slide upon each other. 0 and e are the tubes through which the air passes. l) is a cup formed in the side of one of the ends of the tube, and E is adamper in one of the tubes.

Not only does this ventilator supply fresh air to a room, and. in such a way as not to subject the occupants to any draft, but, it placed in a close apartment with no outlet but itself, it will work. alternately in both directiens, now filling the apartment with pure air and then earryin g oil th mixed and x'itiatell air.

Having thus fully described my invention, what I claim as new, and desire to have protected by Letters Patent of the United States,

1. A ventilator oi'tlie character hereinbclore described, whereby the currents of air are deficcted from a direct course on entering the apartment to be ventilated, and are thrown upward in a vertical direction, substantially as and for the purpose setl'orth.

2. A ventilator provided with an adjustable frame, substantially as and for the purpose deseri bed,

The combination in a ventilator of an adjustable frame, an. air pipe or pipes, and a damper or dampers lbr regulating the supply of air, substantially as described.
