in order that those skilled in theart to which \Vithiu the diffusion-box are arranged a seour invention appertains may know how to rics of louvers 12, which serve to divide and make and use the same and fully appreciate direct the currents of air. These louvers are 5 its advantages, we willproceed to describe the composed of sheet metal and consist of an same, referring by numerals to the accomoutside piece 13, bent into rectangular form 4 panying drawings, in whichi and with its upper returned ends secured by Figure 1 is a front perspective view of a rivets Ill to the diffusion-box l, and 15 desigdiffusion-box with ouriniprovenients attached nates parallel pieces of sheet metal having thereto. Fig. 2 is a rear perspective view. l their ends bent at a right angle and secured Fig. 3 is an end view with the plate or door i by rivets 16 to theend portions of the part 45 in its extreme open position. Fig. a is a veri 13, all as clearly shown. The proportions of tical section taken on the line 1/ a of Fig. 2. these louvers relatively to the diffusion-box I Fig. 5 is a perspective view of the louvers rei are such that a space occurs at each end bemoved from the diffusion-box, and Fig. 6 is l tween the louvers and the end of the diffusionbox in order that the returned ends of the plate or door 4: may be free to vibrate therein.
From the construction shown and described it will be readily appreciated that we are enabled to produce our improved device with great economy and that when in position the air-currents may be readily controlled and maintained by the adjustment of the vibrating plates or doors t.
When a car supplied with ventilating devices of the type described is in motion, the plates or doors of the diffusion-boxes in front of the exterior deflectors are opened to such an extent as to cause the ingoing currents of air to be deflected upward and toward the l roof, and the plates or doors of the diffusionboxes on the opposite sides of the outside deflectors are preferably turned to their lowermost position in order that the outgoing currents induced by the partial vacuum occuring on the rear side of the outside deflectors will travel in a plane below that at which the ingoing currents enter the car, thus effectually separating the fresh and vitiated air and avoiding all disagreeable drafts upon the passengers.
Having described the construction, operation, and advantages of our improved ventilating device, what we claim as new, and del sire to secure by Letters Patent, isi 1. The diffusion-box I adapted to be secured l wall or other part of a car, 1 with an interior plate or door having a flange and in position within the in combination having returned ends pivotally connected at its lower portion to the box, and with a series of recesses or depressions in the edge of one of said ends; and a flat metal spring with one end secured to the upper portion of the box, and its free end provided with a projection adapted to cooperate with the recesses or depressions in the end portion of the plate or door, substantially as and for the purposes set forth.
2. In a diffusion-box such as described, in combination with the box, vibrating plate or door, and spring for holding the latter in adjusted positions, louvers arranged within the box and terminating away from the ends of the diffusion-box, whereby a space is provided for the ends of the vibrative plate or door, substantially as hereinbefore set forth.
3. In a diffusionbox such as described, louvers secured therein and consisting of an outer rectangular frame secured at its upper end to the difiusion-box, and parallel strips with returned ends attached to the ends of the rectangular frame portion, substantially as described.
In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
