VENTILATING. CAR-DOOR.

SPECIFICATION :forming part of Letters Patent N o. 469,794, dated March 1, 1892. Application filed December' Z6, 1891. Serial No. 416,221. (No model.)

To all whom t may concern;

.I Be it known that I, CHARLES T.' SCHOEN, a citizen of the United States, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented a certain new and useful Improvement in Ventilating Car- Doors, of which the following is a full, clear, and exact description.

In some freight or box cars ventilatin g-doors are placed in opposite sides of the carfor'use when ventilation of the car is desirable or necessary, and, in addition,-close or solid doors are provided for use when ventilation is not required. Each door is provided with trolleys or hangers, fastenings, &c. Thus doublev ex-V pense and double dead-weight are involved, four doors in all being necessarily employed.

The object of my invention is to combine a Ventilating and a close or non-Ventilating door iu one structure, whereby I get in two doors all the advantages of the four doors of the common construction.

In practicing my invention'I provide a door having a fixed Ventilating-panel and a close panel movable to cover and to uncover the ventilating-panel according to requirements.

In the accompanying drawings, in the several figures of which like parts are similarly designated, Figure lis an elevation of my door with a portion of the movable panel broken away to expose the Ventilating-panel back of it. Fig. 2 is a cross-section, on a larger scale, broken out in the middle and taken in the plane of line w Fig. l; and Eig.A 3 is a longitudinal section, same scale as Fig. 2, broken out in two places and taken in the plane of line y y, Fig. l.

The stiles da and rails b b of the door I prefer to make of two pieces of seven-eighthsinch stuff each. Before the stiles are united I insert in rabbets in one of the halves of each L-shaped strips of metal c,one of the ends of which strips extends over into like rabbets in the other halves, and to these other halves I secure the Ventilating-panel d and a close fixed panel e. Y Opposite ends of these panels are secured to the halfrail f.

The Ventilating-panel I prefer to use consists of a sheet of mild steel having the punched-up openings g staggered all over the sheet. The openings are protected from ingress of rain and snow by downwardly-projecting hoods g', extending half-way, the other halves-of the openings having the inwardly and upwardly projecting hoods gzito insure free ingress and. egress of air. This form of ventilator forms the subject of a concurrent case entitled car-ventilator, and while it is the one I prefer to use I do not limit my invention in combined Ventilating and close doors to its use, but may use and mean to include in my claims herein any and all forms of ventilators available for this purpose.

h is the movable close panel. This panel is arranged to be slid up and down in the grooves which'are `formed by the rabbets in the stiles and lined with the metal strips c and the panels d e, as before described, and

it is supported over the Ventilating-panel by means of an inturned tongue i on its lower edge fitting in a groove j in the half-rail f and over the projecting upper edge of the panel e. By lifting the panel h out of engagement with the panel e said panel 7L maybe dropped down in the grooves of the rails, so as to uncover the Ventilating-panel.

The movable panel may be bulged where it enters t-he grooves in order to assist in keeping it in place and prevent shattering.

The close'panels are ribbed or corrugated, as indicated at k, to stiften them.

After the several panels are in place the halves of the stiles and rails may be united by screws or other means and the door hung in any approved manner.

The metal panels are light and strong and l economically produced by pressing or striking up in dies or otherwise.

The close panels may be of mild steel also but I may substitute other suitable metal for steel, and obviously other material than metal maybe used for these panels or some of them, though I much prefer metal panels.

Instead'of making single panels extending the width of the door, they may be otherwise constructed.

Obviously the principle of this combined Ventilating and close door is applicable to other than car-doors.

What I claim isl. A Ventilating-door having a fixed venti- .lating-panel, a fixed close panel, and a close IOO panel arranged in Ways on the Stiles and movable over the Ventilating-panel at pleasn re to close it, and also movable from snch ventilating-panel and over the close panel to open the Ventilating-panel, substantially as described.

2. A door having grooved Stiles and rails, a close panel and a Ventilating-panel fixed in Said grooved Stiles and rails, andaclose panel arranged Vin said grooved Stiles and movable therein to cover and uncover the Ventilatingpanel, Substantially as described.

3. A door having a Ventilating-panel and a close panel, rabbeted Stiles in which they are fixed, a half-rail having a groove partly over which groove the close panel projects, and a close panel movable'in said Stiles and having a tongue on its lower edge to enter the groove in the half-rail and engage the proj eating pormy hand this 24th day of December, A.
