J. Q. G. SEARLE. GAR HEATING APPARATUS.
No. 461,283. Patented Oct. 13,1891.
UNITED STATES PATENT OFFICE.
JOHN Q. C. SEARLE, OF. CHICAGO, ILLINOIS.
CAR-HEATING APPARATUS.
, ZPECIFICATION forming part of Letters Patent No. 461,283, dated October 13, 1891.
Application filed March 4, 1891.
To allwho'm, it mayconcern:
Be it known that I, JOHN Q. QSEARLE, a citizen of the United States, residing at Ohicagofin the county of Cook and State of Illinois, have invented new and usefulIinprovements in Oar-Heating Apparatus, of which the following is a specification.
This invention relates to improvements in that class of hot-water warming apparatus shown and described in my patents, No. 311,534, February 3, 1335, and No. 340,825, April 27, 1886, in which the water is heated in a single coil and made to circulate through separate and distinct lines of pipe on each side of the car and requiring but one expansion-chamber for the heating apparatus in each car; but owing to the increased size and length of railway-cars as now constructed it is found desirable that increased heating capacity be provided and. more hot water supplied to the circulating-pipes Without enlarging the heater, as the space in the stove-room is limited. 1 My present invention consists in providing a hot-water warming apparatus comprising a heater, two separate and distinct heating and circulating passages of any approved form, a water-uniting fitting, a water-dividing fitting, an expansion-chamber, two separate descending pipes, circulating-pipes that heat each side of the car separately, two return-pipes,
' a water-uniting fitting for uniting the returnpipes, a water-dividing fitting for returning the cooled water to the separate heating and circulating passages from which it started, whereby I am enabled to increase the heating capacity of the apparatus and supply more hot water to the circulating-pipes without enlarging the heater.
'The apparatus may also comprise one or more cocks or valves, whereby an even circulation and an even temperature can be effected on each side of the car, which in a cold day with a strong wind blowing against one side of the train of cars has heretofore made it impossible to warm that side. of the car.
The annexed drawing, illustrating the invention, is a perspective of a hot-water warmin g apparatus with the heater in section, showing the arrangement of parts, whereby the water that is heated in two separate and distinct heating and circulating passages is confierial No. 383,756. (No model.)
fitting to a water-dividing fitting. The cooled water is returned to the separate heating and circulating passages from which it started.
The numeral 1 designates a heater provided with a heating-coil 2 and a heatingpassage 3, though any other approved form of heating-and circulating device will answer for heating the Water that warms the car. After the water has been heated it is conducted through a fitting 7, a pipe 5, a waterdividing fitting 15, and two descending pipes 9 and 12 to the circulating-pipes 10 and 13 that heat the car, and by the pipes 11 and .14 the separate flows are returned to a wateruniting fitting 16, and by a pipe 17 the united flows are delivered to a water-dividing fitting 18, whereby the cooled water is'returned to the separate heating and circulating passages from which it started.
In order to secure an even circulation and an even temperature on each side of the car, I place in the pipes 11 and 14 one or more cocks or valves 19 and 20 for regulating the circulation.
Should the water circulate faster through the pipes on one side than through those on the other side, one of the valves may be partly closed, and the circulation thus retarded sufficiently to cause both flows to reach the fitting 16 in about the same time.
The expansion-chamber 6 is provided with a safetyvalve 21 to prevent explosions, and a funnel-cock 22 for supplying to the circulation any loss of water from evaporation or otherwise. As the expansion-chamber communicates with all parts of the apparatus, any loss of water can be thus conveniently supplied at one point. By this construction, also, but one expansion-chamber, one safety-valve, and one funnel-cock are required for the ap paratus in each car, thereby avoiding .the use of separate expansion-chambers for opposite sides of the car, and the consequent increased attention required of train-men to see that each side of the heating apparatus is safe and in proper condition for use.
I do not herein broadly claim the c0mbina-.
liquid-heatin g passages therein, a plurality of independent radiators communicating with i the liquid -heating passages, and a temperature-equalizing chamber, pipe, or passage communicating with the upper ends of the said liquid-heating passages and with the radiators, as such constitutes the subject-matter of my application for Letters Patent filed October 9, 1890, Serial No. 367,565. a
1. The combinatiornin a hot-water Warming apparatus, of a heater, tWoseparate and distinct heating and circulating-passages, a Water-uniting fitting 7, a Water-dividing fitting 15, the pipe 5, that connects said water-uniting fitting with said Water-dividing fitting, the circulating-pipes 10 and 13,that heat the car, the pipes 9 and 12, that connect said circulating-pipes with said Water-dividing fitting, the water-uniting fitting 16, the pipe 17, and the Water-dividing fitting 18, that returns the cooled water to the heating and circulating passages from which it started. a
2. Thecoinbinatiomin a hot-Water Warming apparatus, of a heater, two separate and distinct heating and circulating-passages, a Water-uniting fitting 7, a water-dividing fitting 15, the pipe 5, that connects said water-uniting fitting with said Waterdividing fitting, the pipes 10 and 13, that heat the car, the return-pipes 11 and 14, provided with one or more cocks 19 and 20, whereby an even circulation and an even temperature may be produced on each side of the car, the pipes 9 and 12, that connect said circulating-pipes with said water-dividing fitting, the Water-uniting fitting 16, the pipe 17, and the Water-dividing fitting 18, that returns the cooled Water to the heating and circulating passages from which it started.
In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
