FIRE-ENGINE HEATER.

SPECIFICATION forming part 4of Letters Patent No. 542,065, dated July 2,

Application filed March 25, 1895. Serial No. 543,067. (No inodel.)

To all whom t may concerns Beit known that I, HERBERT E. PENNEY, of Minneapolis, Hennepin county, State of Minnesota, have invented certain new and useful Improvements in Fire -Engine I-Ieaters, of which the following is a specification.

My invention relates to lire-engine heaters, and the object I have in view is to provide a simple and convenient device to be used in connection With the engine-boiler for keeping the water therein hot at all times While the engine is in the house and also'maintaining a high pressure of steam so that the engine will be always ready for immediate use in case of fire.

A further object of my invention is to provide an auxiliary boiler or heater adapted to go with the engine when it is drawn out of the house and which will be carried along with the engine when it starts without requiring an attendant to disconnect the same from the furnace or heating apparatus, which operation necessarily consumes considerable valuable time and delays/the starting of the engine.

My invention consists generally in providing a fire-engine. boiler With an auxiliary boiler permanently attached thereto and arranged to be carried With the engine Wheuit goes out to a fire, in combination with asuitable stove or heater arranged to receive the auxiliary boiler when the engine is standing in the house, whereby the Water in the engineboiler will be kept circulating through the auxiliary boiler, and a high pressure of steam maintained at all times in the engine-boiler; and, further, my invention consists in various combinations and constructions, all as hereinafter described, and particularly pointed out in the claims.

The invention will be more readily understood by reference to the accompanying drawings, forming part of this specification, and

Figure l is aside elevation of a fire-engine with my invention applied thereto. Fig. 2 is a side elevation of the stove, the shell or covering therefor being shown in vertical section. Fig. 3 is a plan View of the boilerand the stove, showing the auxiliary boiler in its normal position over the fire, its position when the engine is in use being indicated by dotted lines. Fig/i is a vertical section of the auxiliary boiler itself and the cover for the same whenthe engine is in use. Fig. 5 is a transverse section `on the linear tc of Fig. 4.

In the drawings, 2 represents the boiler of a fire-engine of the-ordinary construction as it appears when not in use in the enginehouse. At the rear of the engine and a short distance therefrom I provide an upright stove 3, having the smoke or outlet pipe 4, and provided in its side nearest the engine with a vertical opening 5. This opening is normally closed by swinging doors 6 and is of sufficient size to receive the small auxiliary boiler when the engine is backed into position in the house.

Theauxiliary boiler comprises the hollow heads '7 and 8, the head 7 having the large central opening, as shown in Fig. 5, and the head 8 being provided with a central opening in its upper surface, which is covered by a plate 9 securely fastened to the head by screws or bolts, as shown in Fig. 4. movable plate permits access to the interior of the head to the series of tubes -or flues 10, which connect with the heads 7 and 8. The opening `in the center of the head 7 permits the flames to pass up between the tubes of the heater and therefore subjects the Water Howing through the tubes to a very intense heat, so that in avery short time after the auxiliary boiler has been pushed back into the stove the Water in the boiler Will begin to circulate through the auxiliary boiler, and in a short time will begin to generate steam very rapidly. The heads 7 and 8 are each provided on the side of the auxiliary boiler next to the engineboiler with openings Il and l2 to receive the pipes 13 and 14,\which connect directly with the boiler of the engine, the pipe 13 entering the boiler near the Water-line, While the pipe la passes through the boiler-shell near the bottom thereof. p

Suitable couplings 15 and 16 are provided in the pipes'l and 14, so that when the engine` starts out of the house the auxiliary boiler may be swung round to the position over the fuel-box, as shown in Fig. 3, and when the engine is in use at the tire the auxiliary boiler may be swung around to the This re-- IOO 4o vents the unnecessary heating of the house other position indicated by dotted linesinl Fig. 3, Where it Will be entirely out of the Way when it is desired to fire the engine-boiler.

A hood or cover 17 is provided, made of suitable'material and having a handle 18, said hood being arranged to slip down over the auxiliary boiler as the engine starts out of the house, thereby preventing in a measure rapid cooling ot' the iiues of the heater, and also preventing any dangerot' the firemen being burned by coming in contact therewith. The hood is also provided With a longitudinal slot Which permits it to be slipped down over the auxiliary boiler, the pipes 13 and 14 sliding in the longitudinal slot. By grasping the handle 18 the auxiliary boiler may be swung to either of thepositions indicated by dotted lines Whenever desired. The doors 6 are provided with openings at the top and bottom, through which the pipes 13 and 14 respectively pass, and each ot' said pipes is provided with asliding sleeve or collar 19 and a spring 2O coiled about the pipe between the doors and the collar, which upon being put under compression bythe collar 19 will hold the doors closed While the auxiliary boiler is in nits normal position Within the stove. The collar 19 is held from slipping on the pipe by an ordinary set-screw.

For summer use, particularly, I provide a shell or cover 21 for the stov-e 3, as shown in Figs. 1 and 2. This covering may be made of any suitable material and covered with asbestos or other non-conducting material, if desired, and is preferably provided at its base with a series of openings 22, through which the air circulates and carries the heat radiated from the stove up into the top of the house or into the chimney, and thereby preduring hot Weather. The casing or shell 21 is also provided with openings on either side corresponding and registering with ,the doors in the stove, both the fuel door and the doors 6, heretofore described. The stove lire-pot is preferably lined up with tire-brick to aid in retaining the heat around the heater, and also to prevent the rapid burning out of the stove from the intense heat Within.

The operation of my device is as follows: The normal position of the heater when the engine is standing in the house is shown in Fig. 1. A hot tire being maintained in the stove, the water in the boiler soon begins to circulate through the auxiliary boiler and steam is generated very rapidly until it reaches the desired pressure, usually from sixty to eighty pounds.

When an alarm ot' tire is sounded and the engine starts out of the house, the auxiliary boiler is drawn out of the stove as the engine passes out and, after the hood or cover 17 is placed over the auxiliary boiler, the Whole apparatus may be swung around over the fuel box out of the Way. There being a high pressure of steam already generated in the boiler,

steam and in a few moments the engine Will be ready for service again. In all other engine auxiliary boilers Where the heater is left in the house it is necessary to disconnect the pipes and make connections with a tank, or else leave an attendant to Watch the fire in the stove or furnace after the departure ot' the engine, While in other devices, where the heater accompanies the engine, it has been found impossible, with the gasoline-burners usually employed, to heat the Water sufiiciently to generate steam, and for this reason the devices of this kind have been practically Worthless.

It is obvious that the size of the auxiliary boiler may be changed at pleasure in order to increase the heating-surface, and it may be made of various kinds of material Without departing from the spirit of my invention.

Having thus described my invention, I claim as new and desire-to secure by Letters Patent- 1. In a device of the class described, the combination with a movable steam boiler and its re box, of an auxiliary boiler arranged outside the main boiler, but connected therewith for circulation, and a stationary stove or heater into which said axuiliary boiler may be inserted, and from which it may be separatedby the movement of the main boiler, substantially as described.
