UNITED STATES PATENT OFFICE.
JOHN Q. o. SEARLE, or CHICAGO, ILLINOIS.
CAR-HEATING APPARATUS.
SPECIFICATION forming part of Letters Patent No. 461,282, dated October 13, 1891.
I Application filed March 4, 1891. Serial No. 383,755. (No model.)
To all whom it may concern.-
Be it known thatI, JOHN QC. SEARLE, a
citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Car-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, 1885, 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-oars 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.
My present invention consists in providing a hot-water warming apparatus comprising a heater, two separate and distinct heating and circulating passages, a combined water-uniting and expansion chamber,awater-dividing chamber, a pipe that connects the water-uniting chamber and water-dividing fitting, two separate descending pipes, two separate sets of circulating-pipes that heat the car, and two return-pipes for returning the cooled water to the heating and circulating passages from which it started,by which I am enabled to increase the heating capacity and supply more hot water to the circulating-pipes without enlargin g the heater. The return-pipes may be provided with one or more cocks or valves,
whereby an even circulation and an even temperature can be effected on each side of the car, which on a cold day with a strong wind blowing against one side of a train of cars has heretofore made it impossible to warm that side of the car. y
The annexed drawing is a perspective of a hot-water warming apparatus with a heater in section, showing the combination of parts whereby the water that is heated in two separate and distinct heating and circulating passages is conducted to the circulating-pipes that heat each side of the car, and afterward by two return-pipes the cooled water is re-.
turned to the separate heating and circulatand circulating passage 3, though any other approved form of heating device having two separate heating and circulating passages will answer to heat the waterthat warms the car.
After the water has been properly heated itis conducted through pipes 4 and-5, a combined water-uniting and expansion chamber 6, pipe 8, water-dividing fitting 15, and descending pipes 9 and 12 to the circulatingpipes 10 and 13, that heat each side of the car separately, and by the pipes 11 and 14 the cooled water is returned to the separate heating and circulating passages from which it started.
It further consists in providing means whereby an even circulation and an even temperature is secured on each side of the car. To obtain this result I place in the pipes 11 and 14 a cook or valve, as 19 and 20, by means of which the circulation may be regulated.
Should the water circulate faster on one side than on the other, one of the valves may be partly closed, and the circulation thereby retarded enough to cause both flows to reach the heater in about the same time.
The expansion-chamber 6 is provided with a safety-valve 21 to prevent explosion and Ya funnel-cock 22 for supplying any loss of water to the entire apparatus at one point, as all parts of the apparatus communicate with said expansion-chamber 6. The necessity of having a separate expansion-chamber for each side of the car is avoided and the consequent increased attention of the train-men to see that each side of the apparatus is safe and in proper condition for use is very much lessened.
The advantages of a hot-water warming apparatus having two separate heating and circulating passages, a combined water-uniting and expansion chamber, a water-dividing fitting, and two separate sets of heating and ci-rculating pipes will be obvious, as thereby but one water-unitin g and expansion chamber and tion,what I claim herein as new, and desire to secure by Letters Patent, is
1. The combination, in a hot-water Warming apparatus, of a heater, two separate and distinct heating and circulating passages, a combined Water-uniting and expansion chambeer 6, the pipes 4 and 5, that connect said heating and circulating passages with said wateruniting and expansion chamber, the Water-dividing fitting 15,the pipe 8, that connects said water-uniting and expansion chamber with said Water-dividing fitting, the circulatingpipes 10 and 13, that heat 'the car, the pipes 9 and 12, that connect said circulating-pipes with said water-dividing fitting, and the redistinct heating and circulating passages, a I
combined water-uniting and expansion chamber 6, the pipes 4 and 5, that connect said.
heating and circulating passages with said water-uniting and expansion chamber, the water-dividing fitting 15,the pipe 8, that connects said water-uniting and expansion chamber 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, and the return-pipes 11 and 14, that return the cooled water to the separate heating and circulating passages from which it started,provided with one ormore cocks, whereby an even circulation and an even temperature may be produced on each side of the car.
In testimony whereof- I have hereunto set my hand and aflixed my seal in presence of two subscribing witnesses.-
