IMPROVEMENT IN VENTILATORS.'

@te .tlgitulz refont. tu in these hitters atnit mit mating put tf the Smau Beit known that I, AARON HUM-"F, of Swedes/boro, in the county of Gloucester, and 4Stato of New Jersey,

have invented Vcertain Improvements in Foul-Air Ventilators; and I do hereby declare that the following, teken in connection with the drawings which accompany `and form part of this specification, is u. description of my invention suihcient to enable those skilled in the-art to practise it.

The object of my invention is to provide a simple and eiiieient means by which apartments, in which lamps are used, (and especially those burning camphene and other fluids, whiclx,in burning, give o much smoke or offensive odor,) may be readily ventilated. A I

My invention consists in providing, in connection with an outlet-pipe for conveying away the foul air, an adjustable and removable funnel, and which is 'so arranged, in relation to the outlet-pipe, that it may be swung into position for use, or'out of position when not in use, and, also, may have its-opening closedby merely changing the position of the parts.

'In tho drawings- Figure 1 represents an apartment in which my device is shown applied to an opening in the Qliiumev` and to receive the fum-es ofla lamp placed on the mantel.

Figurc2 represents alongitudinal section of the same on a larger scale. The middle representation of my apparatus iniig. 1 showsthe same when it, withthe funnel, is turned up out of the way, and the right-hand representation shows it with theY funnel removed, and the outlettube closed, as hereinafter explained.

.A is afunnel-shaped piece of tin, or other appropriate metal, hating thereon a tubular part, B.

C is another tubularv piece, of sniiicient diameter to admit snugly the tube B, and to which it may be held by a thumb-screw, or otherwise. j

The upper part of tube 0,-I prefer tomake with a short sleeve or tube, a, placed at right angles to it, and with-itsborc opening into it. Thissleevc is made to tit upon ono. end of another tube, D, which latter is designed to'be inserted into the opening prepared for it in the wall, or chimney, or partition, or other place, in such manner as to convey away -from the apartment any impurities which enter the funnel. i

Eis athumirnut, which fits a thread upon the plug or` cap upon the end ot' tube D, and which thus serves y to hold firmly the part C to the part D, and so to make a close joint, as well as to insure the sustaining of C in whatever position it may be placed about I) as a centre. i l

F F are valve-openings in that part of tube D which is confined within the sleeve a, and which serve to ntord an unobstructed outletfor the foul air from the room-whenever the opening in tube C coincides with one of such openings or' passages, but not otherwise. i i

G is a thumb-screw, Awhich allows the funnel to be removed from or held securely to the tube (l` The operation is as follows:

The parts being arranged, as shown in'gure, and applied to any suitableopening previously prepared for Vin the wall'of the apartment, the lamp is placed beneath/it, upon a table, mantel, or other piece o furniture,

tho vertical adjustment of the funnel permitting its .adaptation to the lamp, whether the latter be standing in a high or low position. The tube D, by being placed more or less into or through wall or partition, also admits of a range of horizontal adjustment relatively 'to the location of the lamp. The turning of the sleeve a upon tube D not only permits the pendent parts to be swung up out ofthe way when not in actual use, but also, by turning the same a portion of the way around,l as, forinstanoe, a quarter circle, as shown iu the righthand sketch in`g.'1, insu-res the closing up of the outlet by causing they sleeve to cover the valves or orifices F F in tube D.

Thisapparatus is particularly serviceable in sick-chambers, or wherever lamps `are required to be burned .all`night. v

It is evident that the whole may be removed from the wall and laid aside until wanted for use, and then applied at's moments notice.

It wiii'algo b e perceived that -by'my moie of* cons trotingand connecting the several p'artgtiley may all be taken apart for conveniencevof ypaciringieml transportation, and can as readily be puf; together again.

Ielaim afventlator having a. swinging foui-air-ppe, combined with an outlet` er discharge-pipe, substan- Atimllyfns and for the prirpoeedescribed. v

I' also claim che above in combination with an adjustable fimnei, snbstantiily as and for the purpose described.A v
