Application .tiled March 13.

To all 'whom ztrmay concern.: l Be it known that I, RrcHAnnWEB BUR-Y NET'I', of the city of Montreal, in the Prov. ince of Quebec, Dominion of Canada, a citi zen of the United States of America, have invented certain new and useful Improvef ments in Berth-Ventilators; and I de hereby declare that the following is a full, clear,

and exact description of the same.

The invention relates to the ventilation ing or resting and more particularly to berths or Staterooms. of passenger coaches and steam-boats. A source of great discomfort to passengers occupying apartments-of this nature such as berths in sleeping coaches, etc., is the inability to obtain proper ventilation without exposing the occupant to view. -This is 'because of the fact that the windows are unsatisfactory and although the aisles of the cars are easily ventilated, this fresh air may not be utilized, asthe curtains must be kept closed to screen the passenger from view. I have discovered that this fresh air from the aisles can be directed into the berth by mounting deflectors in -the curtains. I Aam aware that horizontal louvers have been tried but they have two serious defects in that they can be seen through at certainv angles, and they do not intercept the passing fresh air of the aisle and deflect `it therethrough.

According to my invention a plurality of parallel vertically disposed and nested and relatively spaced louvers of angular crosssection are mounted in an opening in each curtain and connected together by resilient one curtain of each pair facing oppositely to those in the other curtain of the pair in order that the louvers in one curtain may 'deflect air into the berth and the louvers in the other curtain deect air out of the berth thus securing proper circulation. The resiliency of the straps permits the undulations of the curtains due to even slight draft of air through the coach to undulate the ventilator and move the louvers successively into more exposed positions within the car and thus more effectively intercept the air and deflect it into the berth. rlhis fiexibility of the ventilator has advantagestherefore. The angular form of the louvers presents angular passages between them which, when the louvers are relatively spacedV a distance equal to or less i -*Specification of Letters Patent. i f

depth of a louver, cannot be seen through from any position, and these louvers may therefore be disposed vertically and consequently at rightI angles movement of the air in -the aisle, the effect being that fresh air is intercepted and deflected into the berth.

h For full `comprehension, however, of my invention companying drawings forming a part of this specification in which similar reference characters indicate the same parts, and wherein:

Figure 1 illustrates the curtains of a berth in elevation and furnished with my deflectlng louvers; Fig. 2 is a horizontal sectional view taken on line II H Fig. 1;' Fig. 3 is an enlarged horizontal sectional view of one than the transverse of the sets of louvers; and Fig. 4 is a detail A perspective view of one ofthe louvers re'- moved.

The side of the coach is indicated at b, the windows at c, seats at d and curtains at e. Theselparts may all be as usual and are not described in detail, the curtains having rectangular openings k cut therein for receiving the louvers.

'Each louver is formed from sheet metal or other suitable material and of Wedge form with externally concaved sides o, the free edge of one of which is llanged as at p, the other being curled to form a bead g for strengthening purposes, and, at the same time, preventing accident by blunting the edge. The louvers of each set are connected together and to the curtain at the upper -and Ilower edges of the opening k by straps reference must be had to the ac- Y The louvers of one curtain of each pair being arranged to face oppositely to the llouvers in the other curtain of the pair not only secures a proper circulation within the berth but enables ventilation to be obtained no matter in Which direction the car may be traveling. What I claim is as follows 1.v A ventilator comprising a plurality of vertical nested and relatively spaced louvers of angular cross-section, the apex of each louver extending Within the adjoining louver.

2. A ventilator for berths of passenger 5 coaches and the like comprising a curtain' havinga pair of openings therein, a series of vertical louvers disposed across each of said openings, said louvers being of angular cross-section, the louvers of one series being 10 arranged to face oppositely tothe louvers
