IMPROVEMENT IN CAR-VENTILA-TORS.

Specification forming part of Letters Patent No. 171,61 l, dated December 28, 1875 application filed December 1, 187 5.

To all whom it may concern:

Be it known that I, GEORGE F. GoDLEY, of Philadelphia, in the coun'ty of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Gar- Ventilators; and do hereby declare the fol lowing to be a full, clear, and exact descrip-I tion of the invention, such as will enable othl ers skilled in the art to which it pertains to Vmake and use it, reference being had to the accompanying drawings, which form part of this specification, in which- Figure l is a longitudinal Vertical section of a car, showing the application of my invention. Fig. 2 is a perspective of the revolving elbow. Fig. 3 is a perspective of a modication. Fig. 4: is a plan of the revolving elbow. Figs. 5 and 6 are broken elevations, showing my invention applied to freight and fruit cars.

My improvements have for their object to provide meansv for more thoroughly and effrciently Ventilating passenger and other railway cars than has been heretofore possible.

My invention consists in the peculiar con-- struction, combination, and arrangement of parts hereinafter more fully described, having reference particularly to the provision of a swiveled elbow-pi pe, intended to be placed, by preference, underneath the door of the car, connecting with the interior of the latter by means of a registered opening, and generally so arranged that the forward motion of the car will cause said elbow to swing around in such manner that its exit-opening will be toward the rear of the train, the suction of the latter having the effect of drawing the air out ofthe car through said elbow.

Referring to the accompanying drawing, A designates a passenger-car; B, the floor, and C the roof, of the same. D D designate openings in the bottom of the car, located at suitable intervals in any desired position, either inthe aisles, or underneath or between the seats or at the sides. These openings are provided with registers d, below which they receive the collars e of an elbow-pipe, E, said elbow by this means being swiveled, so as to turn freely in any direction upon its vertical axis. The moair out ofthe interior of the car, as indicated by the arrows y.

If desired, the exit-opening of the pipes Ey may be closed by valves e', which will remain closed when the train is at a state of rest, but will automatically fly open when in motion.

Instead of a swiveled elbow a single pipe or a series of pipes, two or more, as shown at F in Fig. 3, having outwardly-opening valvesj f at each end, may be employed. In either case fresh air may be supplied to the cars through a perforated tube, Gr; arranged below the roof, and communicating', by branches g, with exterior short pipes II, having inward-- ly-opening valves h h'.

For grain, fruit, or other freight cars, the

registers d may be dispensed with, and a foraminated tube or trunk, I, substituted therefor, said trunk being combined either with the elbow E or pipe F.

The elbow E may be advantageously combined with the exit-pipe of a car-urinal, K, and' by producing a forcible air-current through the same will have the effect of carrying o the ammoniac-al and other obnoxious vapors usually incident to such fixtures.

What I claim as my invention is-" l. In combination with a car, a swiveled elbow-pipe depending from the door, as shown and described, whereby, through the suction produced by a moving train, said elbow-pipe will receive and expel the 'vitiated air from the interior of the car, substantially as set forth.

2. In combination with the car-floor, having an opening'or recess, D, the swiveled el' bow-pipe E, having the collar or ange e, substantially as described and shown.

3. In combination with the swiveled elbowpipe E, applied substantially as shown, an automatically .opening and closing valve, e', substantially as shown and described.

4. In combination with an air-pipe placed below the door of a car, an automatically open.

ing `and elosingvelve or \v'ai`ves,isubstaintinlly as shown anddescribed.

5. In combination with a. perforated pipe, Gr, for admitting air to the car in theupper section, a. pipe or tube for drawing off the vitated atmosphere through the floor or sides@` substantially as shown and described# In testimony that I claim the foregoing hztvehereunto set my hond this 27th day of November, 1875. GEORGE F. GrODLEYA.`
