SPEGIFICATION forming part of Letters Patent No. 514,457, dated February 13, 1894.

l To all whom may concern: l

Beit known that I, THOMAS GUNNING, of

Pittsburg, in the county of Allegheny and consumers wherein airisforced in over the i Vboiler located over the furnacedoor.

1 Lpipes are screwed into the casing, and to their projecting outer `ends arejoined the globu- "3Q i u nected with each other by pipes 5.

gratos to combine with and consume the smoke, and it consists in an improved construction, whereby air entering at the sides is `heated by exposed side-pipes and forced in at the front of the furnace.

l In the drawings, in which similar numerals v' l I' `indicate like parts, 2 represents the front wall 125 of the setting, through which pass the airinlet pipes 3, there being one pipe for each These lar reservoirs or collectors 4i, which are confrom the end collectors arethe bent pipes' 6, "which are embedded inthe inner sides of the `uiurmice` walls, as shown, and are partially i of the setting and are provided with the mufjexposed to the heat of the furnaces.

p These pipes pass throughapcrtu res in the side-Walls i @ding-device '7, shown `in Fig; at. This device consists simply of a box or receptaclesecured to the end of the pipe and having a slotin its side sothat the entering air makes an angu- `lar turnbefore entering the pipe. l have found i vthat this device is fully as veffective as the complicated diaphragm muiiiers now employed, while it is much simpler and cheaper. Through the outer portions of the reservoirs et pass the injector-pipes 8, which are joined by T-connections to the steam-pipe 9 passing in front of the boilers. y

To increase the supply of air through the -pipes `6, l may use steam-injector pipes 10 Leading' passing through the outer ends ofthe mutd ers, and to bring a further supply of heated air t0 the central boilers, Where there are several boilers in the battery, l employ the vertical pipes l', having T-connections with the connecting pipes 5. These pipes l lead up into the breeching of the boiler, and at their upper ends are connected to the inlet pipes l2 passing through the uptake and having at their outer ends suitable rotatory dampers to regulate the .amountk of entering air.

The action ofthe device is as followsz-The air entering through the muiiiers at the ends of the pipes 6, is heated by the action of the dame upon the exposed portions ofthe pipes, rand thence passing to the reservoirs is forced in over the dre, and the heated air uniting with the smoke, consumes the same. Additional air is drawn down through the vertical supply pipes if necessary, being heated in transit by the waste products of combustion, and supplied to the reservoirs. do away with the most of the noise occasioned by the entering air, and the amount of air may be increased by-turning steam into the injectors lO passing into said muflers.l

I claim as my iuventionl. Ajboiler' furnacehavin'g a pipe partially yembedded inits side wail and having an open `end projecting therethrough, an air pipe leading through its front casing above the grate, an injector in the air pipe, and a connection 'between said pipe and the pipe in the side wall; substantially as described.

A boiler having a front reservoir pro- The mu fders vided with `an air pipe projecting through its Y front casing, a vertical pipe extending therefrom up throughy the breechin g, and provided with an extension projecting through the side of the uptake and opening into the atmosphere; substantially as described.

3. A boiler having an air pipe partially einl bedded in its side Wall, said pipe opening out- 'wardly through the side wall and being'connected to a reservorin front of the furnace, and an air pipe leading from said yreservoir into the space above the grate; substantially as described.

v 4. A boiler having an air pipe partially emlroo bedded in its sidewall, said pipe opening outi wardly through the side wall and being @011 nected to a reservoir in front of the furnace, an air pipe leading from said reservoir into the space above the grate, and an injector passing into thel frontair pipe; substantially as described.

5. A battery of boilers having air pipes partially embedded in the side Walls, air pipes leading through the front casing and connected to the side pipes, vertical pipes also 1o connected to the front air pipes, leading up through the breeching and passing through the side of the uptake, andinjeetolsentermg the front air pipes; substantially as described. l

In testimony whereof l have hereunto set my hand.
