UN TED STATES PATENT OFFICE;

FRANKLIN B. GIESLER, OF MILWAUKEE, WISCONSIN.

SMOKE-CONSUMING FURNACE.

SPECIFICATION forming part Of Letters Patent No. 240,405, dated April 19, 1881.

. Application filed January 10,1881. (No model.)

To all whom it may concern:

Be it known that I, FRANKLIN B. GrnsLnR, of Milwaukee, in the county of Milwaukee, and in the State of 'Wisconsin, have invented certain new and useful Improvements in Smoke- Oonsuming Attachments for Furnaces, 820.; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to devices for collecting and returning smoke to furnaces for consumption, and will be fully described hereinafter.

In the drawings, in which similar letters of reference indicate like parts, Figure 1 is a side view of my invention. Fig. 2 is a central vertical section of a part of a smoke-reservoir which forms part of my invention. Fig. 3 is a horizontal section of the same on the line w w of Fig. 1; and Fig. 4 is a vertical central section of my device, and of the furnace in crosssection.

A is the boiler, and A the furnace, the smokeflue B of which, instead of entering directly into the smoke-stack, extends to a reservoir, 0, which it enters at its lower end, just under a set of cold-water fines, D, which occupies about half the length of the reservoir.

Immediately above the flnes I provide a pipe, E, which extends to the smoke-stack, and through the center of the fines I extend a pipe, F, which at its top receives an air-pipe, F, and just below the top of the reservoir I provide the pipe F with openings b and a sleeve, K, which is toggled to the shaft K of a pinion, K meshing with a worm, K on rod K, and having a suitable crank, K The air-pipe F has a valve, F near the pipe F and a damper near its lower end. A pipe, F connects the pipe F with a blower, G, which, in turn, is connected with the furnace by a pipe, G, having dampered branches 9 g, which enter beneath the grate. The pipe G and smoke-flue are connected by a pipe, G having a valve, 9 at its lower end. This valve has a weighted lever, H, one end of which is connected by a cord, H, with the damper in the pipe E.

Cold water is admitted to the fines D at a from the street-mains, and as it flows through the flues it is heated by the smoke. It then flows to the boiler through pipe d.

The furnace and smoke-reservoir may be either adjacent to each other or some distance apart without affecting the operation of the apparatus.

The operationis as follows: Open the damper E and close the dampers in g g in the branches. Now the fire may be lighted in the furnace, and until sufficient heat has been generated to raise steam in the boiler the smoke will pass through pipe B into the reservoir 0, and thence out to the smoke-stack through pipe E; but when there is a pressure sufficient I connect the fan or blower G, in any suitable manner, to the boiler, and, having started the fan or blower, I open the dampers in branches g and allow the valves E to close, and drop the sleeve K below the openings 12. Now, while a portion of the smoke and gases will be carried out of the reservoir through the pipe E, a greater portion will be drawn by the fan or blower through openings 1) into pipe F, through pipe F into the fan or blower, from whence it will be forced out into the furnace beneath the grate, carrying with it a supply of oxygen, which is drawn in through the pipe F. This pipe has a clack-valve, to stop any back flow of air, and a damper to regulate the inflow, The damper E in pipe E is weighted so as to be nearly closed, and is connected with one end of the weighted lever H of valve g by a cord or chain, H, so that in case the branches g g of pipe G should become obstructed the valve 9 yielding to the pressure, would allow the smoke or smoke and air from the blower to ascend in the pipe G and at the same time the handle of lever H would draw upon cord H and open the valve E in pipe E, so as to afford an egress for the increased volume of smoke.

What I claim as my invention is- 1. In combination with the smoke-flue of a furnace, a smoke-reservoir, G, air-inlet F,pipes F, F, and G, and a blower for drawing the products of combustion from the reservoir and delivering them beneath the furnace-grate, all as set forth.

2. In combination with the smoke-flue B, a

reservoir, 0, pipe F, air-pipe F, a blower, and

In testimony that I claim the foregoing I the pipes connecting the reservoir with the h ave hereunto set my hand this 15th day of 10 chamber beneath the grate, as set forglh. 1 December, 1880. 3. In combination With the smokeue anc 5 reservoir having pipe E, the return-pipe G, FRANKLIN GIESLEB" upright pipe-G valve g and damper E, the Witnesses: two latter connected by a cord or chain, H, S. S. STOUT, as set forth.
