EBPECIPICATION forming part of Letters Patent No. 305,251, dated September 16, 1884.

. Application filed March 10, 18953. (No model.)

To aZZ whom it may concern:

Be it known that I, ISRAEL TOWNSEND, a citizen-of the United States, residing at Ports mouth, in the county of Norfolk and State of Virginia. have invented certain new and use ful Improvements in Car-Ventilators; and I 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, reference beinghad to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention has for its object the ventilation of railroad-cars from beneath by forcing the air up through certain pipes by means of certain mechanical devices fastened to the bottom of said car and between the trucks of said car.

My invention is illustrated in the accompanying drawings.

Like letters represent like parts in all the figures. a

Figure 1 represents a side View of railroadcar with my invention attached ready for use;

Fig. 2, a broken-away end View of said car, showing a section of reservoir or tank, with connecting-pipes; Fig. 3, a reversible blower with connectingpipes; Fig. 4, adjustable or split pulley attached to axle or shaft of carwheel.

The letterA represents body of railroad-car; B, the horizontal pipe running along whole length of floor and 011 the inside of car, with smaller perpendicular pipes I) open at the top, putting out of and being attached to pipe B.

There are two horizontal pipes, B, and two sets of pipes, b, one on each side of car, as shown in Fig. 2. The pipes 12 may be four feet in length, longer or shorter, and may be provided with stop-cocks a, for the purpose of preventing the passage of air when it is so desired.

5oder side of pipe 13, to which it is attached in such a manner as to allow the passage of air from one pipe to the other. There are two curved pipes, c, as shown in Fig. 2. The reservoir or tank Ois penetrated by pipe d, which descends into tank 0 a greater or less distance.

with stop-cock g ,'to be used so as to open or close said water-pipe.

D D represent hollow metal pipes putting out from pipe (1 and radiating so as to enter the metal case of blow-wheel, as shown in Fig.

1. Said pipes D D are provided with stop-' cocks cc, to be opened or closed, as hereinafter shown.

E represents a reversible blow-wheel, provided with a metal casing securely fastened to the bottom of the car-body A. The blow-wheel E is so constructed that when the car is running in a forward direction it willbe revolved by means of belt f, attached to pulley Gand to pulley q, so as to force the air into the hollow pipe D, when the stop-cock 0 will be opened, so as to allow the passage of air through pipe D, and stop-cock 0 will be closed, so as to prevent the passage of air through pipe D. XVhen the car is running in an opposite direction, the blow-wheel will be revolved in an opposite di' rection by means of said belt and pulleys, and force the air into hollow pipe D, when stopcock 6 will be openedfso as to allow the passage of air through pipe D, and stop'cock a will be closed, so as to prevent passage of air through pipe D.

The circle F represents car-wheel. The dotted circle G represents the adjustable or slip pulley securely fastened to the shaft or axle 71. of car-wheel F, with belt f attached.

In Fig. 3 is given a detailed drawing of the reversible blower, consisting of blow-wheel E,

curved arm or band m, extending on both sides of blow-wheel, as shown in drawings, and containin g axle box or brass q, in which the journal of axle of wheel E revolves. There are two boxes, q-oue on each side of wheelalso -partly inclosed by metal casing H, and the consisting of two hollow pipes or tubes, l) D, with stop-eocks c c.

In Fig. 4 is given a drawing of split pulley G, divided into halfsections 9, said half-sections being held firmly together by means of metal bands or straps i, which are securely fastened to both sides of pulley G by means of bolts 91, passing through pulley G and straps i7, and being tightened by means of nuts. The hub or center of" pulley G is provided with a metal box, 7;, which fits upon shaft or axle 71, and is locked to said shaft or axle by means of key Z in such a manner as to prevent said pulley G from slipping. Pulley G is provided with flanges, and is of suflieient width to prevent belt f from slipping ofi.

Then the car is in motion, the blow-wheel E will be revolved in such a manner as to force air into the pipes D D, as hereinbel'ore described; from thence into pipe d,- from thence into the water contained in tank G, where the air is nuritied of all dust or dirt; from thence intoand along pipes B; from thence into both sets of pipes I); from thence into interior of car A; from thence out at openings in top of ear, thereby cooling, purifying, and ventilating said ear.

Having fully described my invention, what I desire to claim and secure Letters Patent for is In a car-ventilator, a reversible blower, E, provided with twin pipes D D, said pipes hav ing suitable valves to change or check the current of air, and converging into pipe d, all being situated and operated beneath the ear, substantially as and for the purpose set forth.

In testimony whereof I afiix my signature in presence of two witnesses.-

ISRAEL TGXVIv SEND.
