T011, whom it may concern:

Be it known that I, HENRY SPnNonR BLAoKMo E, a citizen of the United States,

residing at Mount Vernon, in the county of. Westchester and State of New York, have tering said cars or vehicles, through the me the air is caused to.

dium of a device whereb enter the car or vehicle t ough the purifying a 'paratus by the movement of the vehicle to w 'ch the apparatus is attached, the said apparatus being provided with a means Wherey th'ent ring air is automatically'caused to pass thro sociated with disinfectant or odorizin -sub stances and purified from dust and de eter1- ous contaminations, whereby the air in cars and vehicles is caused to circulate and is kept in a pure and healthful condition automatically with the movement of the vehicle.

My new'.and im roved apparatus consists of new and nove features, as hereinafter more clearly set forth refe'rence being had to the accompanying drawings, in whi ch Figure 1, is a vertical transverse section of -my apparatus for automatically purifying and disinfecting or odorizing the air or atmosphere of cars. Fig. 2, is a longitudinal transverse section of one of a pair of funnel' shaped air-receivers provided with a conical screen and means for holding-same in yielding and extended position. Fig. 3, represents asection of a car; with a portion of the roof and platform-nood broken away to show the apparatus, as when located outside of the car, and its discharge pipe extending therein. Fig. 4, is a vertical transverse section of a car with the a paratus located therein.

On the rawing, the letter A designates the disinfecting or urifying chamber, preferably of cylindrical orm, ,and provided interiorly with a series of shelves or trays I), each pro- 11 the same and is charged or as' v vided with a central opening c surrounded by a wall (Z, the openings and their walls increaS- mg in diameter from the bottom tray up. A gauze e is secured by 'a metal band or ringlf over the top of each walled. opening, 't e auze ofthe lower tra being of anycapillary abric'material and '0 such size that its edge shall spread over a good portion of the bottom of its tray.

An opening g is made -in one sidevof the casing A forthe inflow of a liqui'd'disinfectant or odorizing substance from a on h, located at the outside of said opening, t e said "cup being fed from a liquid receptacle h" which is-su ported by the said cup and a 'metal band connected with the upper part inFigs.1, 3,and 4 q of the casing A, as shown of the drawings.

The disinfecting or purifying chamber A is provided with an imperforate cover 71/, the air passing into the upper part of the said chamber Athrough a pipe the upwardlyextended end of which 18 surmounted by a horizontal section 'L, the'opposite ends of which are provided with funnel sections, or

wind-receivers i, i the flared endsor mouth 1 of each being adapted to engage the base s of .a spiral or conically wound wire spring over which is fitted a gauze covering 1-. conical ring p is connected by lugs p with the mouth of each wind-receiver 'i/ '21, as shown in Fig. 2, to stiffen the receivers as well as toinsure a draft around the rear of the gauze covering, and thereby free same of dust or other substance which might otherwise ace cumulate thereon. The horizontal section ":1, between the wind-receivers, is rovided with an internal guide k, in which is iitted a sliding rod 70, having circular plates Z, Z, secured to the opposite ends thereof, to close the base of the funnels when brought in contact there'- with.

' The lower part of the casing A is provided with an outlet-pipe m, having a rectangular valve '0 and a funnel-shaped discharge end, as shown at t, Fig.3.

The cover h, of the purifying and saturating compartment A, is adapted to be secured in position by means of screw-bolts and nuts w, so that access may be had to the interior of the said compartment. Thus the the, 1 means and perfummg agent to the air passing I let.

various gauzes may be removed successively,

and. replaced, and the apparatuscleaned and recharged whenever same may be deemed necessary.

It will be further noted that the aLir-purifying and disinfecting compartment is provided with aseries of shelves surrounding the gauze diaphragms, so that the first compartment is adapted to separate'the dust from the entering air, which, by reason of the cir culating air above it, causes the dust to accumulate upon the shelf first next to the in- The second or central shelf, about the secondgauze diaphragm, is adapted to be filled with a substance, such as sodium eroxid', which is capable of absorbing car on dioxid or sulfurous gases, or other similar impurities, from the entering air, with the generation of a correspon ing amount of pure oxygen'dislodged from the sodium perthrough. The gauze communicating with this channel, or compartment, is preferably of fibrous nature, such as asbestos, or some textile material, so that by capillarity, the disinfecting and odorizing fluid 1s carried up from thechannel about the diaphragm and this saturates the textile gauze through which the purified air passes, and whereby, in passing through the said gauze, the air becomes saturated 'with odorizin 1 odorizing fluid in the channel about this texand: disinfecting contents of the fluid. "T e disinfecting'and tile gauze diaphragm is kept automatically filled to a uniform level by means ofthefeed device ,h communicating with the cup ,7 on

the exterior of the apparatus, as hereinbefore degiribeg. h f

[18301; e important an 7 g the ,entering cones, through which the air passes from a direction opposite to that of mgving vehicle, are provided with a,

orseparating dust, cinders,- and other impurities, suchas gauze 1', which gauze is' automatically clearedfof adhering dust, cinders, .orrother substanceawhich might hat-'- urally accumulate thereon, by a means comisforcedd invention,

. 'therewith-in'such} a manner-that the gauze 1s maintainedina vibratory condi tion duringits operation, which means, as specifically illustrated, constitutes a spiral spring placed inside of the filtering gauze. Another important and distinguishing feature of my invention is the" fact that it is actuated by the movement of the device into a body of air or atmosphere, which movement of the device is essential to its operativeness, and an important feature in combination with the air purifying, disinfecting,

and odorizing apparatus through which the air passes to the interior of the vehicle to which attached, for the purpose of supplying to the interior of the vehicle, a purified, disinfected, and healthful atmosphere, the device being operated by forcing it into a body of air by the action of the moving vehicle with which it is incombination, so thata current of air is introduced into the vehicle through the apparatus in a direction opposite to that in which the vehicle is traveling, the device naturally creating a current of air by being forced into or againstthe resistance of the atmosphere at a speed greater than that at which the atmosphere, exterior to or surrounding the vehicle, is traveling.

It can thus be seen that the combination of the device,as hereinbefore set forth, with a moving vehicle, produces a new and useful result, the utility of the device being gaged' or governed by the speed with which. the vehicle travels, while the purified and disinfected air entering the vehicle throu h the device, will be regulated and contro ed at will by a means so located as to obstruct orv release the current of air againstthe pressure created by the moving vehicle, such as valve 1).

It can be readily seen that a device of the 'with which the smaller apparatus is combined, would be comparatively useless, were it not for the'fact that its'operation is actu-' ated by the resistance created by the moving vehicle against the body'of air into which it such movement. A greater result is there ore obtained from a smaller ve 'cle in accordance with my device when 0 erated in combination with v the moving features of my invention lies in the act that:

Byl employing an a paratus ofthis char acterit can be seen t at four iniportantresuits are obtained: First, the separation of dust and suspended impurities from the air pu ties; andfourth, te chaof the and revitalized air with su stances air through the apparatus controlled by the valve 0, and entering into the same through the inlet ducts controlled by automatic means for directing the air therein from abody of air forced into the apparatus by the funnel-shaped exterior device being forced into the atmosphere by the moving'vehicle, all of which results can be clearly ap- Patent is:

preciated.
