CAR-HEATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 445,090, dated January 20, 1891.

Application filed January '7, 1889 Serial No. 295,647- (No model.)

To (all who/1t it may concern.-

Be it known that 1, JAMES H. SEwAnL, of Portland, county of Cumberland, State of Maine, have invented an Improvement in Cz'ir lleating Apparatus, of which the follow ing description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object toimprove the construction of apparatus employed for heating cars.

The invention herein shown is an improvement on the car-heating apparatus invented by John 13. Porter, yet is applicable to other heating apparatus wherein two heaters are employed to heat the water for a common set of circulation-pipes.

In ear-heating apparatus of the kind referred to comprising a set of water-circulation pipes within the car and two heaters for heating the same independently or simultaneously at will valves have been interposed between the heaters, so as to control the water in its passage.

In accordance with this invention a simple device is provided in lieu of such valves, which requires no attention and which simply gives direction tothe current, thereby aecomplishing the desired end.

The device herein shown for giving direction to the current comprises a shell or case having a passage through it from end to end and a pipe leading into said shell at one side or formed integral with it, said pipe being bent or formed at a right angle, so that water passing through the pipe will be directed in the direction to which said pipe is turned, yet at the same time afree passage is afforded for the water directly through the shell.

Figure 1 shows in elevation and partial section a car-heating apparatus provided with a director for the warming-liquid embodying this invention; Fig. 2, a vertical section of the director 011 a larger scale 5 Fig. 3, a plan View of the controlling'valve of the car-heating apparatus.

The car-heating apparatus herein shown, to which my invention is applied, comprises a system of water or other liquid-circulating pipes a, an expansioirchamber b, and two heating-coils or communicating portions of the piping c (I, one of the said coils being contained in a heater (7 (see dotted lines, in which a tire may be kindled, and the able inclosing case (1 into which steam is admit-ted by a pipe e, leading from a main steam-pipe c. The coils c d are joined to the circulating-pipes a at the lower end by a T- coupliug j, and at the upper end by a current director g. (Best shown in Fig.2.) The enrrent-director g compriscsa shell or case havin g a passage g through it, and a curved pipe is contained within the shell or case, being formed integral therewith, said pipe having an inlet at one side of the shell or case and bent up within and parallel to said passage to form an outlet considerably above said inlet.

In operation, the water heated, fol-instance, in the coil 0 passes upwardly through the passage 9 of the shell or case 9 to the expansion-tank, thence through the circulatingpipes returning to the coil, and when the coil cl is heated the liquid passes upwardly through the curved pipe g to the expansiondrum, thence through the circulating-pipes, returning to the coil d; or both coils may be simultaneously heated and the liquid contained therein passed through the current-director. By the employment of a current-director the liquid rising from the coil (Z will not ci reulate through the coil 0, and thereby sh0rtcircuit the circulation-pipe, or vice versa, as the direction given it by thcupturncd end of the pipe 5 is sui'iieient to cause it to i'lowupward to the expansion-drum Z); also it will be seen that a current-director fulfills all the requirements, cannot get out of order, and requires no attention whatever.

I do not desire to limit myself to the use of the current-director to the particular system of car-heating apparatus herein shown, as any independent arrangement or location of the heaters c and d may be employed and the function and operation of the current-director remain the same.

I claim 1. In a car-heating apparatus, a system of circulating-pipes within the car and two in otheincoil, as (I, being contained in a suitdependent heaters, both in operative contact with said circulating syste1n,adapted to be operated simultaneously or separately by heat imparted thereto, combined with a current-director interposed at the junction or point of contact of the said heaters and circulating system, substantially as described.

2. In a car-heating system, the combination, with a system of Water-circulating" pipes within the car, of a suitable radiator in contact With said circulating system, mechanism for supplying the said radiator with steam as a primary means of heating said circulating system, and a secondary independent heater also in operative contact or connected with said circulating system and adapted to heatihe same, combined with a current-director, substantially as described, interposed at the junction or point of contact of the primary and secondary heaters, and the circulatingpipes, substantially as described.

In a car-heating system, the combination, with a system of circulating-pipes within the car and two independent heaters in operative contact with said circulating system, each having exposed radiating-s11rfaces, one of the said heaters being adapted to contain a fire and the other to receive steam, combined with a current-director, substantially as described, located at the point of contact or junction of the said heaters and circulating system, substantially as described.

4. In a car-heating apparatus, the circulating system located within the car and having an expansion-drum, two independent recep tacles containing the circulating-pipes connected at each end with the circulating system, a steam-receiving case inclosing one of the said receptacles, combined with a current-director located at the junction of the upper end of the said receivers, and the circulating system,substantially as and for the purposes set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

JAMES H. SEVVALL.
