CAR-HEATER.
SPECIFICATION forming part of Letters Patent No. 499,017, dated June 6, 1893.
Application filed March 2, 1 893.
To all whom it may concern.-
Be it known that we, PETER J. FITZGERALD, of Hyde Park, in the county of Norfolk, and DAVID F. BARRY, of Boston, in the county of Suffolk, State of Massachusetts, citizens of the United States, have invented certain new and useful Improvements in Oar-Heaters; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
Our invention relates to heaters designed especially for use in connection with cars for street railways, and has forits object the production of a heater, and its accessories, of comparatively simple and cheap construction, by which any desired degree of heat may be generated, and which is designed to be placed in ordinary street railway cars, during the building of same, or after completion, without modifying the construction of any of the parts.
Our invention consists in the means hereinat'ter described whereby a common source of heat is utilized to raise the temperature of the air for heating purposes and to generate steam from a body of water, and whereby the combined heat of the heated air and from the steam is mingled and discharged through outlets common to both into the interior of the car.
It further consists in means for regulating the supply of air to be heated; in the peculiar arrangement of the air and steam conveying pipes and in other details of construction all of which will fully and clearly appear from a reading of the following description taken in connection with the accompanying drawings which form a part thereof, and in which- Figure 1, illustrates in perspective view a car for street railways, a portion of the side thereof being broken away to show portions of our heater in position. Fig. 2 is a vertical longitudinal section of the car a portion of the seat being removed to show the heater proper and the radiators for discharging hot air. Fig. 3 is a vertical central longitudinal section of the heater and its accessories including the oil supply devices, before the same have been placed in the car; Fig. 4 a detail Serial No. 464,401. (No model.)
of a portion of the casing showing different positions in full and dotted lines of the means for regulating the admission of air to the heater; and Fig. 5 is a detail, taken on line a;m of Fig. 1, of the means for discharging when desired the hot air outside of the car.
Like letters and figures of reference denote corresponding parts in the several figures of the drawings.
The reference letter Adenotes the car, which as shown, is of the common type for street railways, and to which the heater is adapted to be applied.
We propose to place the several parts of the heater under one of the seats B, although if desired the parts may be duplicated and placed under both seats.
In or on the roof of the car is arranged a tank or receptacle 0 for holding hydro-carbon oil or other liquid for supplying the burner presently to be described. This tank is formed preferably of a metallic tube closed at both ends and provided .with an opening 0 for filling the tank, the same being closed by a cap or cover a.
d is the supply pipe which opens into the bottom of the tank and leads to the burner.
At the point of connection of the tank and supply pipe, the latter is flared outwardly to form a conical seat for the inner end of a screw plug valve d which is raised and lowered by turning the thumb screw (1 thereon for regulating the supply of oil to the burner. The pipe dis also provided with another valve d which is located in said pipe near the top of the car and readily accessible to a person inside, and by this means the supply of oil may be instantly regulated even when the car is in motion.
Midway of the length of the car is a casing 6 within which is arranged the burner and from which are led the pipes for supplying the heated air and steam. This casing and the pipes are as before stated placed beneath the seat, andare entirely within the car and consequently all of the heat generated by radiation is communicated to the interior, and not to the outer atmosphere as would be the case where the heater is placed beneath or at any other point outside of the car.
Access to the interior of the casing is permitted through a suitable door in the seat, and through a door 6 in the front of the easing, which is provided with a lockinglatch 6 In the upper end of the casing is a partitionfwhich separates the easing into two compartments ff the upper one f, constituting a water chamber which may be filled through the opening f from an overhead tank located in the top of the car, or from the side of the car, or from any other place desired. The partition is centrally raised or arched to provide a concave heating surface for the burner which latter is located in the chamber f immediately below said partition. Extending downward from this partition is an annular deflecting plate 9 which terminates at a point a little above the bottom of the casing and forms a reverberatory chamber and serves to confine the air to be heated to the burner before the same passes to the points of discharge.
At each side of the casing and communicating with the interior of the chamber f are hot air pipes or flues 7L which convey the heated air to the registers t' which latter are located at each end of the car and may be provided with any suitable means for regulating the discharge of hot air therefrom. These pipes h are preferably offset at h to increase the draft of hot air, and for another purpose presently to be explained. Air is admitted to the heater from the under side of the car through a section of pipe j which is connected to the bottom of the casing and is led through the floor of the car. The inflow of air is regulated by a perforated cap j which is conically shaped and fits within the pipe j the sides being formed with slots or incisions j to give the same a yielding pressure against the wall of the pipe to retain it in the desired position. Air is admitted through perforationsj and is deflected downward before its ascension to the burner by the flanged top 7' the object being to divide the air to be heated. The admission of the air is regulated by raising and lowering the cap to present more or less of the perforations above the bottom of the casing to increase or diminish the inflow of the air. On the under side of the top 7' are lugs or shouldersj which by contaotwith the bottom of the casing prevent the cap from being lowered sufficiently to prevent any inflow of air, and thus the pipe j is at all times opened and an ingress of air continually established.
We provide ready means for discharging the heated air outside of the car in the event of the inner temperature thereof becoming too high, as follows: The numeral 1 represents a pipe which is let into the hot air pipe and is carried to any point outside of the car, preferably above the line of the hot air pipe, where it terminates in a grating 2. Within this pipe is a damper 3 preferably of the rocking type which is arranged on a lever 4 the upper end extending above the pipe and fulcrumed 011 a lug 5. The upper end of the lever is concommunicate with the water chamber and serve to convey the steam generated from the heated water. Connected to these sections is by suitable couplings k are the radiating pipes Z, Z, which are let into the air pipes at each side of the casing at the offsets hin the latter pipes. Return pipes Z Z connect the pipes Z and are preferably led into the Water chamber below the water level thereof. The sections is and pipes Z Z carry the steam generated by the body of water within the chamberf' and furnish heat by radiation; which added to the heated air generated by the burner is discharged through the radiators at each end of the car as before stated. In this manner a single burner performs the double function of heating both the air in the lower chamber and the water in the upper chamber, and these sources of heat being combined and discharged through common channels the result is a heat sufficiently intense to raise the temperature in a car to the desired extent even under the most unfavorable conditions of cold.
In operation, the tank and water chamber are supplied with suffioient quantities of oil and water for a predetermined number of trips. The burner is then ignited and the air flowing into the casing is quickly heated to a very high degree of temperature. The hot air after being confined for a short period is carried downward and around the defleeting plate and upward and through the hot air pipes to the registers at each end .of the car. The heat of the burner also at the same time raises the temperature of the water in the water chamber until steam is generated, which passes from said chamber through the pipes located within the hot air pipes, and the heat radiating from the steam pipes minglingwith the hot air from'the burner passes out through the radiators as before stated.
By means of the devices hereinbefore described, the heat generated is under the complete control of the operator. Both the supply of oil to the burner and the air to be heated may be easily and quickly regulated; and the air when heated can be discharged in. any desired quantity both inside and outside of the car at will.
As before stated our heater is applicable to any type of street railway car, and may also, if desired, be employed advantageously on steam railway cars, steam boats and the like.
The several parts constituting our heater are comparatively simple in construction and may be cheaply made, and the cost incidental IIO to operating the heater is confined to the hydrocarbon oil or other liquid consumed.
We propose to employ in connection with the heater a hydrocarbon oil or similar burner in which the combustion is complete and consequently no perceptible odor is discharged within the car with the heated air, and we are enabled to dispense with the usual means employed for carrying oft the products of combustion of the burners heretofore employed. If it should be found that in starting the burner any odoris generated, theimpregnated air may, by the means hereinbefore described, be discharged outside the car until the retort is heated to a sufficient degree to cause a thorough vaporization of the oil and a complete combustion, after which the pure air is allowed to enter the car.
Having now described our invention and the manner in which the same is to be performed, what we claim, and desire to secure by Letters Patent, is-
1. In a heating apparatus, the combination, of a burner, a casing surrounding said burner, having an inlet at its bottom, and means for regulating the inflowing current of air, a plate in the casing surrounding the burner and forming a reverberatory chamber, and hot air pipes communicating with the interior of the casing for conveying and discharging the heated air substantially as described.
