VENTILAT'ING RAILWAY-PASSENGER CARS. No.173y003. Patented Feb. 1, 1876.
' 7 III! e EDwARD' E. HARQBEAvEs' IMPROVEMENT iNVENTI ATING RAILWAY PAs sEnQeE R-c asfQ Specificationforming part of Letters Patent No. 173,003, dated February 1, 1876 application filed I 1 January 7, 1876.
To all whom it may concern:
Be it known that 1, EDWARD E. HAR- GREAVES, of Sarnia, in the county of Lambton and Province of Ontario, Canada, have in-' vented an Improvement in Ventilating Railway Passenger-Oars, of which the following is a specification:
The nature of this invention relates to an improvementin ventilating passenger-cars that are warmed by steam or hot-water pipes coiled under each seat, and, more particularly to ventilating sleeping-cars'so warmed:
The invention consists, first, in inclosing the heating-coil under each seat with a perforated case or muffle, communicating with the external atmosphere through an opening in the side of the car, to retain the influent air-currents in contact with the hot pipes, until such currents have been raised in temperature to the required point; secondly, in a vertical eduction-pipe let into each side wall of the Scar at each berth section, with one or more openings at theplane of the upper part of each berth for the eduction of foul air by means of an exhaust-fan located under the car, and connected therewith by suitable eduction main and cross pipes under the car; thirdly, in a means for regulating the volume of air to be withdrawn from the car, governing thereby the volume of fresh air to be admitted thereto.
Figure 1, Sheet 1, is a perspective view of a sleeping-car fitted with my improved means for ventilating it, the seats, berths, and inner linings being removed to better show the same.
sleeping-car warmed by hot-water-circulating' pipes B, arranged to form a flat coil of' twomembers under each vseat, in the usual manner. O is an exhaust-fan, driven by a belt, D, from a pulley on one of the adjacent axles, which fan is so constructed that it willoperate equally well when driven in either direc- Fig. 4 is an tion. E is an eduction-pipe, running the entire length of the car. undereach side sill. One of these communicates directly with the fan by a short main pipe, F, and the other by a rior linings of the car, at the plane ofjthe upper part of the upper and lower berths, when made up. The pipe is perforated with an opening, a, for the eduction of foul air, which isdrawn out by the fan when the car is in motion.
H is an inwardly-swinging valve hung in an opening in the. side of the exhaust-main F,
andisactuated by a spindle, I, from the inside of the car. By opening this valve more or less, the volume of air to be withdrawn from the car can be regulated as desired. The
more it is opened .the less rapidly will the fan withdraw it from the car. Each coil undera seat is inclosed in acylindrical case, J, closed at the inner, but'open at the outer end, where it communicates with the outer air through an opening, I), made in the side of the car, fitted with a screen, a, of very fine mesh, to exclude'the dust. The top part of the case J is perforated with numerous small apertures, d, Fig. 5, through which fresh air is drawn into the car to replace that withdrawn by the fan. The purpose of the case J is to detain the influent air-currents long enough in contact with the hot pipes to insure their being pleasantly warmed before entering thebody of the car.
Itwill thenbe seen that the air of the car will be continually changed so long as the car is in motion; and that, when the season demands, the air that enters the car fwill be raised to the proper temperature. During the season that no heat is required, the cases J serve to distribute the infliientfresh air in minute ets, from which no unpleasant drafts will be felt.
What I claim as my invention is- 1. The perforated cases J inclosin g the heating-pipes' B of a passenger-car, and communicating with the external atmosphere through openings in the side of the car, in combination with a means for withdrawing or exhausting air from said car, substantially as de- J 3.
