IMPROVEMENT IN HVDROCARBON-FURNACES.

Specification forming part of Letters Patent No. 169,583, dated November 2, 1875; application tiled September 13, 1875.

To all whom it may concern f Be it known that I, PETER M. Qvisr, of

a St. Paul, Minnesota, have invented a certain new and useful Improvement in apparatus for burning coal-oil and other oils as fuel, of which the following is a specification:

The nature of my improvement, and the manner in which the same is or may be carried into effect, .can best be understood by reference to the accompanying drawing, which represents the application of my said improvement to a stationary boiler.

Figure l is a transverse vertical section-in a plane passing through the fire-box of the boiler. Fig.2 is a longitudinal vertical central section of the boiler.

B is a boiler of ordinary '0! suitable con struction. A is a reservoir, occupying the place usually occupied by the fire-box, and in communication, on the one hand, with the oilfeeding pipe gfe d, and, on the other hand, with the watersupply pipefb, provided with cock n, which controls the admission of water. The oil-feeding pipe leads from an oil-supply tank, 0, placed at such height above the reservoir A as to cause the oil to discharge into the reservoir when the oil-feeding pipe is The reservoir A is filled with water to the proper height through the water-inlel pipe I), and the oil admitted to the reservoir passes up through the body of water and floats and burns on top ofthe same. Thus far the apparatus does not materially difier from others heretofore suggested and devised. The flow of oil for burning purposes is controlled by the cock 1), which the engineer opens when the supply of burning oil on the top of the water the water which has entered the pipe, and thus time is lost, and the operation is not performed so quickly, and, indeed, so accurately, as it might otherwise be. To remedy this difficulty I put in 'the discharging end 01 of the oil-pipe a poppet or check-valve, m, which will rise to permit the egress of the oil, but which, themoment the cock p is turned off, will, by the superior weight of the water, drop and be tightly closed against any ingress of the water. The oil-pipe is thus kept entirely. free from water, and thereby the difficulties above named are entirely obviated, and the oil-supply can be renewed at any time instantaneously, and by only momentarily opening the cock. I provide a second cock, g, on the oilpipe, near the tank, as a safeguard against accidental escape of oil. This cock is designed to be employed to turn off the oil only when the-boiler is not in use. An outlet-pipe, c, is provided for discharge of water, which may be used either to draw off all the water or to lower the levelof the water whenever it may be desired to reduce the tire, or, what is the same thing, remove the flame farther from the 'boiler and tlues. The water-level can be regu- Witnesses:
