INVENTOR WITNESSES Nrrn 'rares WILLIAM ALFRED GAY, OF CORRY, PENNSYLVANIA.
CAR-VENTILATOR.
SPECIFICATION forming part of Letters Patent No. 490,960, dated January 31, 1893.
Application led February 3, 1892. Seri/al No. 420,176. (No model.) l
To all whom may concern:
Be it known that I, WILLIAM ALFRED GAY, of Corry, in the county of Erie and State of Pennsylvania, have invented a new and useful Improvement in Car-Ventilators, of which the following is a full, clear, and exact vdescription, reference being had to the accompanying drawings, forming part of this specification, in *which--` Figure 1 is a longitudinal sectional view showing the interior of a sleeping-car berth provided with my improved Ventilating apparatus. The figures on the second sheet of the drawings are made on a larger scale and illustrate in detail the construction of the ventilator. Fig. 2 is an elevation of that part of the Ventilating apparatus which is on the inside of the car. Fig. 3 is a horizontal section on the line III-III of Fig. 2, showing the parts on the inside and outside of the car. Fig. 4 is an elevation, partly in section, on the line IV-IV of Fig. 3 of the hood on the inside of the car. Fig. 5 is a plan view of the outerhood. Fig. 6 is an elevation of the outer hood, shown partly broken away; and Fig. 7 is an elevation, partly in section, of an outer hood of modified construction.
Like symbols of reference indicate like parts in each ofthe views.
The object of my invention is to provide means for Ventilating railway-cars, which will enable the individual passengers to regulate the degree of air current admitted, and so to direct the same that it may eifectually accomplish the purpose of supplying fresh air without the creation of inj urious drafts, which are the occasion of so much discomfort and danger in the systems of ventilation now commonly used. y
The present practice of opening windows in railway cars for the purpose of securing a supply of fresh air is especially unsatisfactory, since the occupant of the seat behind must receive the full force of the entering current regardless of his wishes or physical condition. The greatest need for improvement is in the Ventilation of sleeping-carberths. No forcing in or forcing out process now in use can bring relief to the occupants of the lower berths, and all known appliances have been not only unsatisfactory, but aocomplish their work to the discomfort of those using the upper berths. For the purpose of removing these unpleasant features of modern travel, I have devised my system of individual ventilation, which is adapted to any public vehicle, but more especially to sleeping-cars.
I shall now proceed to describe in detail the construction of that form of my improved apparatus which I believe to be the best for the purpose, premising that the invention is not limited strictly thereto and that the apparatus iscapable of modification in various Ways.
In Fig. 3, 1, 2, represent respectively theY inner and outer partition of the usual double wall of a railway car, and 3 is a horizontal tubular casing which extends through opposite openings therein, and is open at both ends, being held in place by facing rings 5, 5. This casing, while convenient and lending strength to the apparatus, is not essential. Within this casing is a tube 4 open at the ends and rotatory axially in the casingn 0n the outer side of the car and fixed to the tube is a hood or funnel 6 communicating with the tube at one end and open at the outer end so as vto receive or discharge the air current as hereinafter explained. On the inner end of the tube inside the car is an air-distributing tube or hood 7, which is likewise open at its outer end, but is not fixed to the tube, being rotatory independently thereof.
8 is a cap which is set inside the car opposite to the end of the tube and is connected with the tube by arms 9 which pass through an opening in the hood on the inner side of the cap, and are adapted by their connection ofthe tube and cap to enable the former to be turned by rotating the latter. For the purpose of fixing the outer hood so that it shall not be easily displaced when properly adjusted, I employ a rod 10 which is fixed to the outer hood, passes through the tube and through the cap, and is threaded at its inner end, on which is set a nut l1. By screwing up this nut the rod is caused to draw the hood against its seat on the ring 5', and the cap is forced against the inner hood, thus binding all the parts in place. By loosening the nut, the outer hood may be turned by rotating the cap, or the inner'hood may be turned directly by hand. In order to render the setting of the outer hood more secure, I prefer to provide the meeting faces of the hood and the ring 5 with teeth, as shown in Fig. 5. The inner 1nood and its seating ring may be similarly constructed. I preferably provide the outer hood with a screen or sieve 13, as shown in Figs. 3 and 6, which serves to prevent the entrance of cinders or dust particles with the'ingoing air when the funnel is used as an injector. This screen may extend partly or entirely across the open end of the hood. The shape and preferred details of construction of the hood are sufliciently illustrated in in the figures on Sheet 2 andneed no further explanation.
In practice, Ventilating apparatus of this construction are set in the side of the car at convenient places near to the position of the passengers, it may be between the car-windows, as shown in Fig. 1. If the passenger should wish a current of fresh air directly from the outside, the outer hood 6 is turned as above explained so that its open end is directed toward the engine, as shown in Figs.
3, 4c, 5 and 7, whereupon an air current will i enter this hood, and will pass through the tube,being introduced into the car through the inner hood '7, which is turned so as to deliver the current in any direction desired. If however, the inward current is not desirable, an 1 outward air current may be created by turning and fixing the outer hood so that its mouth shall be directed away from the engine. The motion of thevcar will then,by suction, induce an outward current of air through the tube.
' In making the device the inner hood may be reduced in form to a mere opening under the cap 8; or it may be lengthened into a tube of rubber or other device which will deliver the air to or remove it from any part of the berth in which it is placed.
In Fig. 1, I show the application of the apparatus to a sleeping-car berth. It may also be used with advantage in the ventilation of smoking cars and water-closets by exhaustion of air. When used in waterclosets, the ventilator should be placed near the urinal.
If a number of ventilators, say twenty or thirty, were used in each car and idirected so as to exhaust the air, they would create an inward draft at the air-inlet to the heaters so that hot air would be diffused to every part of the car.
In Fig. 7 I show a modification of my invention, which consists informing a small opening 12 at the end of the outer hood opposite to the large end opening. This opening affords a passage through which cinders and dust-particlesenterin g the hood will discharge,
while the air will pass on through the tube into the car.
