HUGH R. IVALKER', OF DETROIT, MICHIGAN.

SMOKE-C ONSUM ER.

E FI forming part of Letters Patent No. 358,135, dated February 22, 1887.

Application filed August 2, 1886. Serial No. 205L783.

To aaZZ whom it may concern:

Be it known'that I, HUGH R. WALKER, a citizen of the United States, residing at Detroit, in the county of lVayne and State of Michigan, have invented certain new and useful Improvementsin a Combined Conveyer and Smoke-Consumer; and Ido declare the following to be afull, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention'relates to that class of devices known as smoke-consumers.

The object of my invention is to overcome the smoke nuisancenow common in furnaces and to save the fuel or heating qualities, a large portion of which escapeiu smoke.

By my device as constructed I am able to obtain a steady and uniform draft, supplying the fire of the furnace with a sufiicient amount of air which has been partially heated, whereby, as it is drawn through the flames'of the furnace, it readily helps to form combustion, thus increasing the heating capacity of the furnace.

My invention relates to the general arrange ment of parts,as hereinafter fully set forth,and pointed out particularly in the claims.

In the drawings forming a part of this specification, Figure l is a side elevation of my in vention attached to a stationary furnace. Fig. 2 is an enlarged View of same, having like parts broken away.

In the drawings, B represents the brickwork surrounding the boiler and furnace, S the common smoke-stack, H the usual hood covering the front end of the boiler, through which the smoke escapes from the fines of the boiler to the smoke-stack, and D the feeddoor, all of which are in common use.

Near the base of the smoke-stack S, I form in theside a port-hole or discharge, 1?. Fitting over said discharge is a recciving-chamber,0. Joining said chamber is a horizontal pipe, J, which leads from the bottom of the chamber 0,

I andis coupled at oneend to the side opening (No model.)

on the mandrel of the fan. A belt passes over said pulley for driving said fan.

Extending from the upper wall of the chamber O and into thesmoke-stack isa dischargepipe, Z. I locate in the smoke-staclgabove the port P,leadiug into the chamber 0, a damper, d,which,when turned to a horizontal position, as show u in Fig. 2,conveys the gas and smoke into the receiving chamber O,where the volatile particles escape th rough the discharge-pipe Z into the stack S; The heavier and more valuable products of combustion by the action of the fan are drawn from the bottom of the chamber 0 through the pipe J, being discharged into the furnace through the pipe K.

When the fan E is not in motion to obtain a direct draft through the smokestack, I turn the wings of the damper d to a vertical position, as shown by dotted lines of Fig. 1.

Leading from the bottom of the fan is a discharge-pipe,K. Said pipe extends downward to a point below the grates G of the furnace, having an elbow'at m. Said pipe extends from said elbow horizontally through the side walls, B, of the furnace, its dischargef being within the furnace and below the grates near the front end.

In the suction-pipe J, at a,I provide an opening or relief-hole. Fitting over said opening is a sliding-gate,c. The object of said gate'and opening is, in case the speed of the fan should cause too strong a suction through the port hole P of the stack, that the gate a may be drawn back, as shown by dotted lines of Fig. 2, when the suction through the stack S and chamber C will be partially checked.

In the discharge-pipe K, leading from the fan to a point below the furnace-grates G, I locate a cut-off or sliding gate, h, having a handle,a,for moving said cut-01f. The object of this cut-off is to enable the'regulation of the discharge into the furnace below the grates. lVhen the gate h is drawn back to the dotted position of Fig. 2, I have a full and strong discharge into the furnace.

When opening the door D to replenish the furnace with coal or fuel, should the fan E be running at a high speed, the sliding gate 0 in the suction-pipe J should be drawn to cut off the suction from the chamber 0, and the gate h should be slightly closed to decrease the volume of discharge into the furnace. This will prevent the escape of smoke from the door D While open.

Should it be desirous to draw into the fan a current of fresh air with that drawn from the smoke-stack through the chamber 0, the sliding gate a should be moved sufliciently to allow the air to pass into the suction-pipe through the port-hole a.

It will be observed thatbylo'eating the sliding gate 0 in the suction-pipe and the cut-off gate h in the discharge-pipe I am able to readily regulate the volume and force of the discharge into the furnace according to the demand of the furnace or of the work it may be required to do.

Having thus fully set forth my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a device for the purposes set forth,the combination of the furnace, the smoke-stack, the damper located therein, the port-hole, the receiving-chamber located over said port-hole, the discharge leading from said chamber into the smokestaclgthe suction-pipe leading from the chamber to the exhaust-fan, the fan, and the diseharge'pipe leading from said fan down to and having its discharge into the furnace below the grate-bars,substantially as specified.

2. The combination of the furnace, the

to said port-hole, the discharge leading from said chamber into the sn1ol e-staek,the pipe J,

leading from the bottom of the chamber to the I exhaust-fan and having the gate 0, located in said pipe, the discharge-pipeleading from the fan to the furnace, havingitsdisehargef below p the grate-bars, and a sliding gate or valve located in said discharge-pipe, substantially as specified.

In testimony whereof I affix my signaturein presence of two witnesses.

HUGH It. \VALKER.
