CONDENSER FOR STEAM MOTOR-CARRIAGES.

SPECIFICATION forming part of Letters Patent No. 699,726, dated May 13, 1902.

Application filed March 24, 1900. Serial No. 10,003, (No m d l.)

To all whom it may concern..-

Be it known that I, FREDERICK W. TURNER, of Cambridge, county of Middlesex, State of Massachusetts, have invented an Improvement in Condensers for'Steam Motor-Oarriages, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention has for its object to construct a condenser which is especially applicable for use on steam-motor carriages.

In accordance with this invention one or more banks of condensing-pipes are arranged in upright position at the front end of the carriage-body--as, for. instance, where the usual dasher is locatedand a pipe leads thereto from the exhaust-pipe of the engine, and a pipe. leads therefrom for the delivery of the water of condensation. Preferably several upright banks of pipes are employed, in which case the pipes of each bank will be dis posed in difierent planes, so that the pipes of each bank will be located opposite the spaces between the pipes of the bank in front of it. Supports are provided for the several banks of pipes, which are attached to the carriagebody, and for simplicity of construction said supports may consist of upright channeled bars attached at their lower ends to the carriage-body, which are adapted to receive in the channels thereof the ends of the banks of pipes, and said upright channeled bars are secured together, and the banks of pipes are connected with said bars. The upper ends of the channeled bars or other end supports are secured together by a plate, which is preferably disposed obliquely to a horizontal plane, thereby directing the air downward onto the pipes. A shield is located back of said bank or banks of pipes, which protects the rider from the heat of said condenser, and said shield is formed or provided with an opening at or near its base, which is provided with a removable cover, whereby the opening may be opened and closed at will, and when opened the heat can pass therethrough toward the feet of the rider. The pipe leading from the conclensing pipes may lead to a suitable receiver, which is provided with a drip-cock, and a pump may be provided for returning when said drip-cock is closed.

Figure 1 shows in sideelevation a steammotor carriage having a condenser embodying this invention. Fig. 2 is a front elevation of the carriage shown in Fig. 1. Fig. 3 is a plan View of the condenser, the obliquelydisposed top plate being removed. Fig. 4: is a vertical section of a portion of the condenser, taken on the dotted line 4, Fig. 2. Fig. 5 is a detail sectional view of the shield, showing the opening therein and the door closing it.

The condenser forming the subject-matter of this invention may be applied to any ordinary type of steam motor-carriage, one type, however, being herein shown for the sake of illustrating the invention, and in the type shown or represents the carriage-body, supported upon any suitable running-gear 5 b, the boiler; c, the engine, andc' the exhaust-pipe leading therefrom. The exhaust-pipe c is connected with a pipe (1, leadingto the condenser, and to the upper end of said pipe d a casting d is secured, which projects forward and has as many outlets as maybe desired, three being herein shown.

e f g represent three banks of pipes,although so far as this invention is concerned I may employ one or any other number of banks of pipes. The banks of pipes are made substantially alike, each bank being preferably composed of a single pipe bent at predetermined points to form a number of horizontally-disposed portions, and the upper end of r.

each bank is connected to the casting d by a suitable union-coupling, and the lower end of each bank is similarly connected to a casting 6', which is constructed substantially the same as the casting d. The pipes will be composed of thin copper tubing. Notwithstanding each bank is herein shown as comprising but a single pipe bent to present a number of horizontal portions, yet said bank is herein referred to as a bank of pipes as Ido not desire to limit my invention to the particular construction shown. The banks of pipes cf 9 are set in upright position and are located at the front end of the carriage-body at the point usually occupied by the dasher, and the horizontally-disposed portions of each bank are located in different planes, so that the horizontal portions of each bank will occupy a position opposite the spaces between the horizontal portions of the bank in front of it. A large condensingsurface is thus exposed to the direct action of the air. The banks of pipesthus provided and connected with the castings d and e are supported in vertical position by suitable end supports attached to the carriage-body. Herein such end supports are made as channeled bars h M, there being one bar for each end of each bank of pipes, and said channeled bars are secured to the carriage-body in upright position and receive in the channels thereof the ends of the banks of pipes. As a preferable way of attaching said channeled bars to the carriage-body I have herein cut away portions of the lower end of each bar, so as to leavea single fiat .piece, as 2, and said fiat pieces2 are bolted or otherwise secured to the carriage-body. The channeled bars h 1 j at each end of the banks of pipes are also secured together, and as a preferable way of accomplishing this result I have connected the bars h andj to the bar 'i,which is located between them,by screws 3, which pass between the horizontal portions of the banks of pipes, and said screws may have mounted upon them suitable sleeves, if desired, although said sleeves are not necessary, so that said screws not only serve to secure the upright bars together, but also serve to connect the banks of pipes to said bars. Pins 5 pass through the middle bar between the horizontal portions of the bank of pipesf to assist in accomplishing the same result. However, I desire it to be understood thatin lieu of end supports of this construction and also in lieu of connecting the banks of pipes to the end supports inthis manner other forms of end supports may be provided and the banks of pipes otherwise connected thereto.

To the upper ends of the end supports h i j'a plate It is secured, which is disposed obliquely to a horizontal plane, as shown, and said plate not only serves to hold the end supports in upright position, but also has a tendency to direct the air downward. The plate 7t .is'formed or provided at each end with a downwardly-projecting ear out out of the plate, through which'bolts pass to secure said plate to the upper ends of the channeled bars, and the holes thus formed provide handles to the ends of said plate to be grasped by the rider.

The casting e at the lower end of each bank of pipes is connected by a pipe e with a receiver e to which a drip-cock e is attached, which may be opened whenever desired.

A pump e of any suitable description, is provided, which is adapted to return the Wa ter of condensation from said receiver 6 to the water-tank, if desired.

An upright shield m is located back of the condensing-pipes, which may be constructed riage, and said shield 'm being thus located back of the condensing-pipes protects the rider from the heat of said pipes; yet said shield is provided at or near the bottom-with an opening we, having a removable cover 712*, so that Whenever desired the heat may be allowed to pass through said opening. At certain times this may be desirable.

It will be seen that by disposing the condensing-pipes at the front end of the carriage body they will be exposed to the direction of the air, and by constructing and arranging them as herein shown a large condensing-surface is provided. It will also be seen that as the throttle -valve of the engine is opened wider and more exhaust-steam thus delivered to the condenser the carriage travels faster and the condensing-pipes will in consequence come in direct contact with more air to augment their efficiency.
