Applicationv filed January 27, .9 3- S ri l No 47% 82- To all whom it may concern:

Be it known that 1, CHARLES C. WORTH- ine'ron, a citizen of the United States, residing at Dunnfield, in thecounty of Warren and State of New Jersey, have invented certain new and useful Improvements in Condensing Apparatus for Steam Motor- Carriages, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

The object of my invention is to rovide. improved means for effectively con ensing all the steam used in the engine of a m tor carriage and returning to the water supply tank withoutthe intervention of a pump, practically all of the water evaporated in the boiler.v

Another object is to increase the available condensing surface-beyond that obtainable in the forward locationwithout detracting from the appearance of the carriage,.and at the same time retainingall the benefits of the circulation of cooling air, due to the forward motion of the carriage.

In the present invention the apparatus is so arranged that the steam exhausted by the engine is successively passed through two or more condensers, each condenser being so placed. that it is brought in contact with a fresh and cool supply of air. Provision is also made for forcing the condensed water into. the water supply tank, without the use of a pump.

This invention consists in the novel construction and combination of the several parts of the mechanism as set forth and described in the following specification and particularly pointed out in the claims.

In the drawings, "Figure 1 is a longitudinal sectional view with some of the parts in elevation, of an apparatus constructed in ad cordance with the principles of this invention. Fig. 2 is an irregular sectional view taken on line 22 of Fig. 1. Fig. 3 shows an elevation of one of the condensers.

Referring to the arts by letters, and in the present exeni li cation of the invention: B represents the oiler or generator, C represents the first condenser in the series, and C represents the second condenser, one of which is preferably located at the front of the vehicle and the other to the rear of and spaced from the first condenser.

E represents the engine, which may be supported in any desired manner by the framework of the vehicle.

F and F represent two fans, the shafts of which are journaled in suitable bearings. One of the fans is located in close proximity to and in the rear of each of the condensers to constantly furnish a fresh supply of air to the outsideof the condenser. These fans may be driven in any desired or suitable the. fan 15" in'a downward direction so that it will pass out under the carriage.

T represents a trap where the condensed water is collected and forced into the'water supply tank W to which the trap. isconnected by means of a suitable pipe V which leads from the tra and terminates adjacent the upper art 0. the water supply tank.

This pipe may be of any desired length,"

but is of such a length as to extend above the water supply in the tank. The tank is also. rovided' with an outlet pipe A, one end of \v .ich projects beyond the tank to permit the escape of any uncondensed vapors. The

other end projects into the tank and terminates above the highest level of'thewater it is desired to maintain in the tank. A suitable closure A is provided for the tank, and a supply 0 ening A may be arranged in the closure. his tank may be located at ,any desired or convenient place, preferably under the seat of the vehicle.

H re aresents a detachable hood covering the boiler 01" generator B and extending from the upper portionlof the condenser C to the upper portion of the condenser C The partition or shield P is preferably attached toand supported by the hood H, so that when the hood is removed, the partition P is removed with it, thereby affording convenient access to the boiler B and the ad acent apparatus. The hood is preferably provid'ed with openings 0 for admitting the atmosphere to the space back of the partition or shield P, and which is drawn against the condenser C by the fan F A pipe G is provided which connects the exhaust outlet of the engine E with the upper portion of the condenser C for conveying the exhaust steam from the engine to the condenser. The condenser C is provided with a lower chamber designated generally by the reference character G which chamber is divided by a partition L into two com artments M, N, one of the compartments l\ being provided with a supply inlet opening M, and the other compartment being provided with adischarge outlet N (see Fig. 3). This condenser is also provided with an upper chamber J which chamber has communication with the two compartments M, N through the medium .of the connecting tubes of the condenser C A pipe S connects the lower portion of the condenser C with the inlet compartment M of the chamber C", and a pipe K connects the, outlet compartment N of the chamber C with the trap T.

The operation of this improved apparatus is as follows; The exhaust steam from the engine E is carried by the pipe G to the top of the condenser C, which is constantly kept in contact with a fresh supply of air drawn from in front of the carriage by means of the fan F.- The air being drawn between the tubes of the condenser C will circulate freely around the tubes of the'condenser before it passes to the fan F. As the air passes the fan F, it will be forced backward against the partition or shield P,

which prevents this air which has become heated by its contact with the condenser tubes from passing backward to the condensers C but directs it downward unde1'-' neath the carriage where it freely escapes with the gases from the boiler B. At times the cooling effect of the air circulating around the tubes of condenser C is sufiicient to condense in the condenser 0 all of the steam from the engine. When, however, the engine E is operated at approximately its full power, a larger amount of steam will be used and at such times a part only of the steam will be condensed in the condenser C. The remainder will be partially cooled and carried with the condensed water to th.e condenser C by the pipe S. In order to insure that condenser C shall be kept in constant contact with a fresh supply of air drawn from the atmosphere, there are provided openings O in-the sides and top of the hood H, which are located back of the partition P, so as to prevent any possibility of the heated air passing from condenser C coming in contact with this fresh supply of air. hose openin s O are preferably made with wings incline fonward in such form as to collect the air as the carriage moves for ward and direct it through the openings 0 to the inner side of the hood H, thus augmenting the action of the fan F This location of the openings back of the partition P is a feature of the invention. The air entering through the openings 0 passes around the tubes of the condenser C causinga further condensation of the steam to take place in this condenser. The fluid passing from the condenser C enters the compartment M of the second condenser and flows upward through some of the tubes of the condenser C into the chamber J. If any steam then remains, it passes also to the chamber J and with it all the water of condensationl that has thus far been formed. From the chamber J the condensed water, the remaining steam, and the uncondensed vapor then pass downward to the compartment N through the remaining tubes of condenser C The remaining steam is there condensed, all of the condensed water then flowing out of the chamber N through the pipe K and into the trap T. The air which has become heated by its contact withthe tubes in condenser C is forced by the fan F against the partition'or shield P from which it passes in a downward direction and escapes beneath the carriage. The partition or shield P? is located so that it may be used also as the dash board for the vehicle and affords a convenient place for mounting the various instruments and gages.

With the improved construction of the partition or shield P, it will be apparent that when the vehicle is at rest, the heat of products of combustion will be prevented from rising into the faces of the occupants of the vehicle, inasmuch as they will be de flected by the partition or shield toward the front of the vehicle and away from the occupants. When the vehicle is in motion the products of combustion will be caused to flow in the opposite direction to be discharged beneath the vehicle.

In stealn motor carriages it has been found necessary to have the water supply 'tank located at a point above the level of limits it is found in practice that with the tank located above the pump, it in all cases is above the level of the outlet of the condensing apparatus from which the water of condensation issues to be returned to the tank. Insystems heretofore-employed this water has been lifted from the lower level of this outlet to the tank by means of' pump. Any derangement of this pump may be followed by serious consequences to of the water, the gradual stoppage of the the invention there is shown and described.

exhaust flow and the back pressure resulting therefrom unless a relief valve is provided to permit the water and back pressure to cscape'and to'give notice to the driver that such derangement has occurred.

One of the objects ofthis invention is to substitute for this expensive and unreliable set of mechanism a simple and unfailingmethod of returning the condensed water to the tank and of preventing all accumulation of dangerous back pressure. When the condensed water flows into the trap T, it settles to the bottom ofthe trap and gradually rising around and inside the; pipe V, forms a water seal at the bottom of the pipe V, causing the urn condensable vapors remaining in the circulation to collect'throughout the system and at the top of the trap T until back pressure has accumulated of sufficient force to overcome the slight resistance due to the height of the pipe V. The water that has been collected in the bottom of the trap T is then forced up through the pipe V and flows into the water supply tank W, while the vapor pressure escapes through the escape pipe A provided for the purpose in the tank W. Thisprocess is automatically repeated at intervals as the condensed water collects in the bottom of the trap T. I

Although in the present exemplification of the preferred construction and arrangement of the several parts, it is to be understood that various changes may be made therein without departing from the spirit of the invention.
