VENTILATION OF BUILDINGS.

SPECIFICATION forming part of Letters Patent No. 398,874, dated March 5, 1889.

Application filed January 7, 1889. Serial No. 295,603. (No model.)

To all whom it may concern:

Be it known that I, STERLING L. BAILEY, a citizen. of the United States', residing in Hyde Park, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Ventilation of Buildings, of which the following is a specification.

That is known as the Smead Dry-Closet System is now quite largely in use, more especially in public -sehool buildings in the United States. Generally stated, this drycloset system of Mr. Smead consists in providing the bui lding-gen erally in the basementwith a privy consisting of a series of seats which open into a horizontal air shaft or passage, so that the fecal matter is dropped upon the bottom of this shaft, where it is speedily dried, much reduced in bulk, and rendered innocuous by a current of air made t-o pass through the said horizontal shaft and in contact with said fecal matter.

For this I purpose the foul air from the building is made use of by conn ecting one end of the horizontal privy-shaft to the foul-air outlets of the build.- I ing and the other end of said horizontal shaft to a vertical stack or ventilating-chimney carried up high enough to produce the necessary I Unless there loe a constant upward draft.

current in this ventilating-stack, it may happen under certain conditions that the ventilation of the building will be checked, and

but requires special management and conl tinued attention in addition to the objection of cost, dce. In the present invention I propose to make the ventilating-stack constant I and certain in its action by a very simple and inexpensive m eans,as follows: It is usual in the l construction of these ventilatin g-stacks to eml body in the structure of the stack, in addition to the large ventilating-tlue, a smaller smoke Ilue or iiues for the purpose of carryingolf the smoke and products of combustion from and giving draft to the furnace or heating apparatus of the building. A metallic smoke-pipe is commonly led from the furnace or other heating apparatus, and I propose in the present invention to utilize the heat of this metallic smoke-pipe to give the necessary draft to the ventilating-iiue, and this I accomplish by surroundin such metallic smoke-pipe with an air-pipe `which leads into the ventilatingliuc, or,what would be virtually the same thing in many respects, inclosing such au air-pipe within the smoke-pipe, the air-pipe in both cases leading, of course, into the Ventilating flue and the smokepipe into the separate smoke-Hue.

In the accompanying drawings, which form a part of this specification, and in which simi-W are horizontal sections of modified forms of the Ventilating and smoke fines, the heating apparatus, and the air and smoke pipes. Figs. 5, 6, and 7 are vertical sections, respectively, on the lines 5 5, G 6, and 7 7 of Fig. 2.

In said drawings, A A represent the rooms of the building to be ventilated.

B is the basement.

C C C, de., are the closets.

D is the horizontal air-shaft beneath the closets; d, the entrance for the air` to said horizontal shaft; d', the exit for the air from said horizontal shaft leading into the vertical ventilating-shaft E.

F is the smaller or smoke flue, usuallybuilt in one structure with the ventilating-shaft, the entire structure constituting the ventilating and smoke stack of the building.

G is the furnace or heating apparatus, provided with a smoke-pipe, I-I, leading from the furnace to the smoke-flue F.

.I is the air-pipe surrounding the smokepipe, open at fj to receive air from the basement, and delivering the same aty j into the Ycntilatinff-shaft E.

A flaring or funnehshaped mouth may be applied at j with good effect.

I find that the heat of the smoke-pipe thus utilized will give a steady and constant cur IOO - perforated with holes to receive air at many points. In the modification shown at Fig. 4 the airpipe is shown inclosed within the smoke-pipe, which is somewhat enlarged for the purpose 0f receiving it. In this latter ligure the draft-Smau, for convenience of illustration, has shown the inlet or mouth of the air-pipe as extending horizontally from the.

side. A better construction Would indicate this opening as extended downward instead 0f laterally.

I claimv l. In a Ventilating apparatus for buildings, the combination, with the dryclosets and their horizontal shaft D, of the Ventilatingshaft E, the smoke-flue F, the furnace G, and the smoke-pipe H, connecting with the smokeflue F, and the air-pipe J, heated by the smokepipe and communicating with the Ventilatingshaft E, substantially as specified.

2. In a building to be ventilated, the combination of the heating apparatus G, flues E and F, smoke-pipe H, connected to the iiue F, and air-pipe J, lheated by the smoke-pipe and connected to theVentilating-ue E, substantially as specified.

STERLING L. BAiLEY.
