mmarnto V 1b all whom it may concern! Be it known that I, Anus S. Jonsson, a citizen of the United States, residuqr at Washington, in the District of Columbia, s bah invetnated and provemen in en: ystems,o w 1 the following 18 a specification.

In late years the extensive budding of small houses and apartment houses with 0 suites havin each a small cabinet kitchen, together wit the lower rice of s has made a atlyincrea use of e ran e freedom from aahes and t e avoidance of handling coal, ther with its great convenience for quick y bringing it into and puttiu it out of, nervi have ms s it a. very esirable ad unct to ousekeeping. One veryserious objection to its use, however, is to be found in the great no, danger of viti ating the atmos here 0 the room with isonous gases 0 and the ob ectionsble odors of cooking. This is' especially true of the small kitchens of a merit houses where a limited amount of air s see allows the air to become quickly vitiat Whenever, from the fouling of the stove, a \vron adjustment, or other disorders, an imper ect combustion of the modern water gas occursi a rapid generation of carso bon monoxid fo lows, whose deadly nature and insidious character have in some instances poisoned and killed the entire family. Such frequent instances of such fatalities have in late years as to have aroused ubho a iprehension and caused the ormu tion 0 rigid municipal rules as to the installation and regulation of the gas The object of my invention is to cure this 4o evil entirely and to make the air of a kitchen pure sanitary and to that end it consists in a s mple system, involving com ratively inexpensive elements of constru on especially related to the gas stove, but. having value also with other forms of heaters.

Figure 1 is,a vertical sectionalv elevation showing two gas ranges in rooms one'above the other cou led up with my ventilating devices, Fig. 8 is a front elevation of the to same, on a smaller scale, Fig. 8 is an en larged view in vertical section taken through the induction ventilstin device, Fig. 4 is a vertical sectional view, owin a modification of the device as sp li to mason es chimneys already built an Fig. 6 is a horiheelisatioa of Letters rum.

combustion zontal cross section of the same on line 5-6 of Fig. 4. In the drawing I have shown two gas ranges, A, A, in two kitchens arranged one above the other, as is common in a rtment so houses, but there may be more, or t may be only one. Asthey are..all equipped substantially alike it will only be necessary to liable to, generate carbon monoxid become foul-"or the flames im i a 10 relatively coolersurface, an b discha into the air to r wi the arbon ioxid, disastrous an often fatal ro- I suits follow. I therefore provide a special flue B which extends from the lowest 1s ran out through the roof and re erably in a covered ventilator. This as performs a double function, in that it not only carries 03 the products of combustion, consisting chiefly of carbon monoxid and carbon diosid, but it-also carries OI all the vapors, gases, and objectionable. odors arising from the cooking. For this purpose ltlltll gas range has an outlet. ipe a, or a in communication with its com ustion cham- 86 her, which pi is connected to the vertical iiue B exten in through the roof. at n )oint in't is flue near the oeili of ouch itchen an o ning is formed whi is preferably cover-ct by a rating or vent re;- 00 later 0. The walls of t e tiue B are perfectly straight and parallel, and between them at a point immediately opposite the vent rs later a vertical partition plate'b is arranger whose lower end extends at an O6 oblique angle to the wall bearing the reister and connects with it at a nut below the star. The upper end'o his part:- tion p ate extends to s short distance above the register opening. The partition plate 6 is set between the two walls ofthe flue, closer to the buck wull than it is to the register wall. In a four inch line the preferred spacing would be about ll llltiltii from the partition late to'tho back wall, and 21 inches from the partition plate to the register wall. The pmmso of this will be more fully explained hereafter.

From the foregoing it Will b15061 that opposite each register opening in the flue 110 Patented Feb. '8, 1e1o.- I "l lflufl M I'm! 0, I. lsrtal IO. mm I is a relatively narrow lpace d behind partition plate which opens into the line above and below, and also a relatively do on a between the partition plate the register, which is closed below but above into the flue so that an updraft space d will induce an npdra ft in the m e by auction, causing the air in the room near the ceiling to pass through the register opening into the space 4: and thence up the flue an out through the roof.

I will now explain more fully the physical principles invo ved in my invention reference being bad more espccially to Fig. 3.

There are two classes of gaseous products to be taken care of from a gas stove. One is the direct roducts of the combustion of the fuel, whici consists chiefly of carbon di-.

. oxid and carbon monoxid, which are very v stove which, while not poisonous 18, neverdoctor in creating a alu h cooking va elect, by

nous. The other is the vnporous exiialation proceeding from the cooking on the thelme, very objectionable, especially in apartment houses. In Fig. ll the poisonous combustion gases are indicated by die heavy arrows and the cooking vapors by the light arrows.

I will now describe the special function of thertition plate I) as regards its spacing, w ich forms the narrow throat. d and the relativel wider space a. r

' It is well nown that gases rise from convectionwith a velocity proportional to the temperature and as the combustion gases GO, and CO, are'quite hot and rise rapidly. they do not need so large a passagcwuv, and hence the small. passageway (1, while tlnmoist and cooler cooking vapors. moving more slowly, require the increased space 1-. Not only this, however, but the inclined bottom of plate 6 makes a tapering threat for the hot combustion uses, which tapering throat crowds them into the narrow S'Plltl' d, and gives a greatly accelerated velocity (0 them and produces the effect of u strain owcrtul suction in space 0 that etl'ectively draws out the P t will be seen from the foregoing, that my invention notonly are the poisonous taken away, hut-they are made to their greater velocity and suction energy,the useful work of relnovin the unpleasant cookin vapors, thus t'id ding tinapartment of al ob'ectionable odors.

As so far dercri the ventilating line is nude of aivanized iron, which is four the w en partitions of a house or in a verti' l llot in a masonry wall. For a single gas r age, a flue 4X4 inches is sullicicnt. but

when'a number of emfloyed, the flue is superposed rnngcs are made of bu proportionately wider.-

ou a e my invention for instullir. n1 ventilating system in a chimney ll airem y built. in such case, I make a galvanized iron box I), one portion of which is rectangular and tits in an opening in the brickwork, the rectangular when being made of'thc same de th as t e brick wall of the chimney. The ot or portion of the box is made tapering, extending from the inner iact 'ol' the chimney fine at the lower end 1, to a point 2 at the top about two-thirds the way across the chimney flue, leuvin r the space a for the updraft of the smoke rom other stoves. This box is formed with a partition plate 6 (similar to b in Figs. 1 and 3). It connects at the bot-tom with the bottom of the box, but stops short of the top of the box so as to leave at. adequate s nice for the odors to was out. Into the inci Mix is tapped the outlet pipe a from the gas range and a pipe 15 connnunicates with the top of the box and extends to a point above the roof. The to of the plate I) is lcaucd inwardly a littize. so as to give a slight convergence to the throat into which the pipe 0 delivers its gases to produce the more forceful induction and suction efl'ect. On the. race of the box is placed the register With this urrun cmcnt it will be seen that the u nlrat't of lot, poisonous gases in pipe u will create an energetic su tion in the )0.\' 1). drawing out all objectionable odors from the upper part of the room which, togcthel with the gases. pass on; through the pipe B. With this arrangement the ventiating pipe it and the inner part of the box being mthcd in the hot currents from-the snmkc pi )(S of other stoves, a greatly stimulntctl updraft is obtained and a more efl'ectivc ventilation.

In carrying out my invention, I would have it nndcrslood that it may be applied to-all heating appliances from which combustion uscs are discharged and which in acoort'laiie with my system are made to remove the vupors of cooking by an inductive eti'cct.

When I employ the term gas stove I would have it understood that I mean to include not only the so called gas range. but also all hentct's operated by gaseous fuel, such as gas heating stoves for warming 11 room, or gas water heater for heating the water supply of the kitchen and bath.
