NUMON N. HORTON, OF KANSAS CITY, MISSOURI.

HEATING, COOLING, AND VENTlLATlNG APPARATUS.

SPECIFICATION forming part of Letters Patent No. 245,380, dated August 9, 1881.

Application filed February 15, 1881.

. To all whom it may concern Be it known that I, NUMoN N. HORTON, doctor of medicine, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented Improvements in Heating, Cooling,

and Ventilating Apparatus, of which the following is a specification.

My invention relates particularly to certain improvements for the adaptation to the ventilation and heating and cooling of railwaycars of a system of ventilation and heating or cooling which I have described in another application.

My present improvements relate, first, to a mode of connecting my system of heating or cooling and ventilating pipes with a locomoa tive-engine boiler for the purpose of applying the invention to railway-cars; second, to an improved arrangement of devices for delivering the heated air and discharging vitiated air; and, third, to a coupling for the hose by which the air is conducted from car to car.

In order that the invention may be fully understood, I will proceed to describe it with reference to the accompanying drawings.

Figure l is a vertical longitudinal section of a baggage-car with my heating and ventilating apparatus applied. Fig. 2 is a longitudinal section of the heating or cooling coil and its accessories on a larger scale. Fig. 3 is a vertical longitudinal section of a passengercar, showing the induction and discharge apparatus therein. Fig. 4 is a longitudinal section of a part of the air-pipe, showing the damper therein and the mode of locking the same. Fig. 5 is a vertical section of the exhaust or discharge pipe and the nozzle therein on a larger scale. Fig. 6 is a perspective view of parts of the hose-coupling detached. Fig. 7 is a side elevation of one of the couplingheads. Fig. 8 is a longitudinal section of the two heads connected.

In Fig. 1 I have shown within the baggagecar, at B, a boiler, an d at E an engine for working the fan F for producing a forced current of air after the manner described in my other application, hereinbefore referred to, for a system of heating and ventilating applicable to buildings as well as to railway-cars.

A represents a drum or casing containing (No model.)

the heating or cooling coil C, which, for heatv ing purposes, is supplied with steam either directly from the boiler B or from the exhaust of the engine, as shown; or it may, in the application of my invention to car-heating, be connected by a pipe, 0, with the locomotive-boiler through a suitable hose and coupling, and by connecting the said steam-pipe with the engine E, as shown, the boiler B in the baggagecar may be entirely dispensed with.

The steam-coil C may either deliver the steam into the air through a pipe, 0, asshown, or the circulation of steam therein may be so regulated as to return the entire Water of condensation into the boiler through a suitable pipe.-

F represents a fan, which is driven by the engine E by means of bolts and pulleys or other equivalent appliances, and is employed for forcing air through the pipe G and branches G G the first passing into the casing or drum A, and the second around the same.

For cooling the air in hot weather cold water, either iced or not, is passed through the coil C. i I

Both the drum A and the lateral passage G are connected to a common conducting'tube or trunk, G by which the air, either heated or not, as desired, is conducted and delivered to hose H H, connected by the coupling I, so as to be passed from car to car throughout the entire length of the train. V represents a two-way valve controlling the bifurcated or branched passages from the air-pipe Gr to the drum A and the lateral pipe or passage G so that the entire body of air maybe passed through the drum A in contact with the heating or cooling coil C or through the lateral passage Gr around the drum, so as to avoid being heated or cooled, or any relative proportions of the air being passed through therespectivechannels. Theentirebodyofair delivered or conducted through the pipe or trunk Gr may be heated or cooled to the required degree.

The degreeot' heat is nicely regulated by the graduation of therespective passages by means of the valve, as aforesaid, the hinged rod J, by which the valve is moved, being notched, as shown, and pressed forward by a spring, K, fixed to the outside of the pipe. The particular notch in which the rod is held indicates the precise position of the valve with respect to the passages which it controls. The ventilating-trunks L, within the passenger-cars,

take the air from the hose H at one end and deliver it to a similar hose, H, at the other end of the car, each hose being\provided with a similar coupling, I, adapted for interchangeable connection, so that the cars may be connected in customary manner either end to, or either end of any passenger-car may be connected with the hose H of the baggage-car in which the air forcing and heating apparatus is contained.

To adapt the couplings to come together interchan geably, they are each made with a semicircular flange, p, to slip within the opposite head, asillustrated in Fig. 8, and each head has on one side a springcatch, q, and on the other a hole, a, to receive the spring-catch of the other head. \Vith the air-trunks L, within the cars, are connected vertical air-pipes M, leading down the sides of the car, between the windows adjacent to the seats, and delivering air under control of registers N, which are accessible to the passengers.

In order to carry off vitiated air from the cars and facilitatethe delivery of fresh air within the same, either heated or not, as the temperature of the atmosphere may require, 1 cmploy discharge-pipes 0, opening near the floor of the car, so as to take the coolerand more vitiated stratum of air, and having within them upturned nozzles P, connected by small pipes Q with the air-forcing pipes or trunks L, so as to cause an active induced current of air. The

discharge-pipes O are located, two in a car, at opposite diagonal corners, in the places commonly occupied by heating-stoves.

It is manifestly unimportant whether the air-forcing fan F be located, as already described, so as to drive the air through drum A or lateral pipe G or both, or whetherit be located within the trunk G with which the said drum A and pipe Gr both communicate, so as to cause an exhaust-current through said drum A or lateral pipe G or both. I have accordingly shown at F a fan which will act by exhaust, as aforesaid; but it will be clearly understood that the force-fan F and the exhaustfan F will not both be required, but either may be used, as preferred.

It is also manifest that any suitable form of rotary or reciprocating blower or air-pum p may be used in lieu of common centrifugal fans indicated.

A damper is shown at T, in the air-trunk L at each end of the car, for the purpose of clos ling said trunk at the rear end of a train.- The shaft of said damper is provided with a crossbar or handle, U, for turning it, and with a square head, W, for the engagement of a pivoted forked catch, X, so as to hold the damper securely in either open or closed position.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

1. The combination, in a railway-car, of a suitable air-forcing appliance, F, an engine, E, for working the same, branched pipes GG G G heater or cooler A O, and a pipe, 0, for supplying steam from the locomotive to the engine E and heatingcoil O, as explained.

2. The combination, in arailway-car, of hotair trunks or conductors L, delivery-pipes M, and forced-exhaust apparatus consisting of the discharge-pipe 0, opening near the floor, and the upturned nozzle 1 contained therein, substantially as and for the purpose set forth.

NUMON N. HORTON.
