VENTI LATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 235,217, dated December 7, 1880.

Appnaaon filed september 3o, issu. (nwmodei.)

To all whom it may concern:

Be it known that I, JAMES H. DOLAND, of Malden, in the county of Middlesex and State oi' Massachusetts, have inventedcertain new and useful Improvements in Ventilating Apparatuses, of which the following is afull, clear, and exact description.

This invention relates more particularly to the ventilation of water-closets in dwellinghouses and other buildings.

It consists of the arrangement, Within the room to be ventilated, of a chambered box adapted for being interiorly heated by the burning of gas, in the usual manner, or otherwise in any of the well-known modes of heating, and also constructed for theair of the room to pass into it and to be therein heated, and from thence to pass upward and out of the building' at any desired point, in combination with an independent flue or lines or passages, which at their lower end or ends open directly to the4 effluvia and vapors arising from the water-closet in a manner to receive such effinvia and vapors before they can escape into the room, and from thence are passed upward, so as to conduct such eftluv'ia and vapors upwardly about and by one or more sides or through the said gas-burning or air-heating chamber without, however, allowing them to enter into or intermingle with the vapors or heated air within such chamber, but in a manner for them to be heated by theburning gas orheat of such chamber, and to conduct them finally, in conjunction with the heated air, &c., from the air-heating chamber to the outside of the building, all substan tially as hereinafter described.

In the accompanying plate of drawings, Figure l is a central vertical section; Fig. 2, in part a face view and vertical section; Fig. 3, a'horizontal section. A

In the drawings, A representsl a ch ambered box, and B a gas-burner arranged within it, to which gas-burner a pipe, G, conducts gas, all as usual in the burning of gas. This chambered box A has a door, D, for convenience of entering it to light the burner, and this door is provided with a glass plate, a, to allow the light of the gas-flame to enter the room in which the chambered box is placed. E, openings in the sides of the box'A for the air of the room to pass into the chamber of the box,

and thus to be heated by the burning of gas therein; F, a passage leading from the upper end of the gas-chamber A, and from thence, running upward, it opens into a passage, G. This passage Gis at the back and sides of the gas-chamber, and one of its walls makes the back and side 'walls of the gas-burning chamber A. This passage G, below the gas-chamber, is open to and to be in communication with the water-closet which it is desired to ventilate, and such opening and communication of such passage should be so arranged as to secure the entrance of the effluvia and vapors from the water-closet into such passage before they can escape into the room, and above the gas-chamberAand the passage Fit runs to the outside of the building at any desired point. H H, passages or flues passing upward through the gas-chamber and passage F, and opening at their lower ends into the back passage, G, below the gas-chamber, and at their upper ends into the passage G above the passage F.

By this construction, combination, and arrangement of gas-chamber and passages or fines F G H, obviously a most thorough and complete ventilation both of a room and of a water-closet will be secured, for the reason that by the heat of the gas-amea strong current is made from the room through the gas or heating chamber, and from the watercloset by the back passage, G, leading thereto, all as is obvious without further description.

Although this invention has been particularly described in connection with water-closets, obviously it is applicable to the ventilation of other places, rooms, Src., and that also other mediums than gas may be used for securing the heating ofthe air within the chamber A, and of the iiues or passages leading from the place to be ventilated.

The fines H H can be dispensed with, if desired, although it is preferable to have them, as it presents more surface for the heat of the gas-flame, &c.

Having thus described myinvention, what I claim, and desire to secure by Letters Patent, 1s-

l. The combination, with the Ventilatingpassage G, of the heating-chamber A, located within but separated by its walls from said passage, and provided with openings E, for

IOO

the admission of' air from the room or apartment, and a tlue, F, leading from the top of the heatingchamber A and terminating above said openings, the said heating-chamber conilnlmcating with the passage Gr solely through thefmedium of the ue F, and the passage G opening below the heating-chamber to receive a current of air from other sources than from the room with which the heatingchamber communicates, the said two currents meeting at the upper terminus of the une F within the passage G, substantially as described.

2. The combination, with a ventilating-passage, of the heating-chamber A, inserted in but separated by its walls from said passage, 15 and provided with the openings E, flue F, and a through passage or passages, H, terminating above said openings.

In testimony whereof I have hereunto set my hand in the presence of two subscribing zo witnesses.

JAMES H. DOLAND.
