A. B. HALLUCK. Auxiliary Heatrs for Steam Fire-Engines.

n N-0 `\4Q653 Patented`Apri|14,1874.

UNITED STATES PATENT OEEICIEo ABSALOM B. HALLOCK, OF PORTLAND, OREGON.

lIMPROVEMENT IN AUXILIARY HEATERs FOR STEAM MRE-ENGINES.

Specification forming part of Letters Patent No. 149,653, dated April 14, 1874; application filed November 9, 1872.

To all whom t may concern.- v

Be it known that I, AEsALoM B. HALLocK, of Portland, in the county of Multnomah and State of Oregon, have invented a new and Improved Auxiliary Heater for Steam Fire- Engines, of which the following is a specification:

My invention consists in so arranging an E auxiliary heater on the hearth or foot plate of a steam nre-engine, and so connecting its heating-coil with the boiler thereof, that'the two shall form one compact and portable machine, capable of performing the functions of a steam fire-engine of the ordinary kind in a more efficient manner, and of effecting an important saving of time at ires with a minimum increase in cost of fuel and labor, as hereinafter described.

Figure l is a rear elevation of part of a steam fire-engine and the sectional elevation of the auxiliary heater. Fig. 2 is a horizontal section of the heater, taken on the line y y of Fig. 1. Fig. 3 is a horizontal section' on the line z a.

A is thepawl of thesteam nre-engine. B is the hearth or foot plate. C is the shell of the vertical cylindrical heater resting on the foot-plate. I) is a coil of pipe within this heater, arranged around the interior wall in a sort of continuation of the lining. The lower end of this coil extends through the heater at B, and connects by a crooked piece, F, with the boiler at or near the bottom, as shown at G. The connection will probably be with a hollow leg of the boiler. The upper end projects at H in the like manner, and connects with the boiler at I, at the water-line or a little below, by a pipe, K. Stop-cocks L are arranged in the connections, near the boiler. The said connections are to be made so they can be readily detached when it is desired to remove the heater. The fuel-hole Mis made in the upper portion of the heater, which is of conical shape, to make suitable connections with the smokepipe. An annular revolving door, O, with a corresponding fuel-hole, is fitted on the conical portion of the heater, to open or close the hole Mby shifting forward and back. A drafthole, P, is formed below the grate U, and provided with a similar annular door, Q, with a hole to correspond with hole P, to open or close said hole by shifting around the heater. A detachable pipe will be fitted upon the pipe N, to conduct the smoke to the chimney when the engine is in the engine-house. This heater will have a iire kept in it-continually for keeping thewater hot, so that steam can be raised quickly when the ire is applied to the boiler. lt is used because the circulation caused by the coil brings the water into contact with aA small re better than if a re is kept up in the larger furnace'of the engine-boiler. It also increases the he. -tin g capacity of the boiler when used in addition to it. It is placed at one side of the fire-door of the boiler, so'as not to interfere with irin g it. By its use steam can be raised in about one-quarter of the time required when not used.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- An auxiliary water-heater, C, arranged and supported on the hearth or foot plate B of the nre-engine, in combination with the boiler A, as shown and described, for the purpose specified.

ABSALOM B. HALLOGK.
