Description
,itinted 51am WILLIAM H. HUNT, OF
BOLTON, CONNECTICUT.
Letters Patent N. 106,940, dated August 30,1870.
` RAILROAD-CAR VENTILATOR.
The Schedule referred to in these Letters Patent and making part ofthe name.
To all 'whom lit may con-cern:
-Be it known that I, VVlLLIAu H. HUNT, of Bolton, Tolland county, State of Connecticut, have invented an Improvement in Means for Ventilating; and the following is declared to be a correct description of the same.
The object of this invention is to ventilato by an ordinary cnr-window without exposing the occupants' of the cav to a draught'of air.
It' a car-window is raised, a current of' cold air flows in direct line upon the side and face of the occupants of the seat immediately in front of' `the opening, cxposing them to chills and colds, and passes on to the seats opposite, and in front and rear of the other inmates of the car.' As a consequence, people, when traveling, prefer to suiier themselves for want of pure air to breathe, than to subject themselves and others to the danger of su'ch exposure.
My invention consists in a method of' admitting air by means'of the opening at the bot-tom ot` the window, giving it an upward and rotating mot-ion by the use ofan ogee-shaped metal strip projecting from the bottoni of the window-frame upward, and in front of the opening, upon which the incoming current impinges, causing it to rise and return upon the window, rebound upward, and pass into the car, and mingle with the warm air above the heads ot' the occupants of the seat, thus furnishing a revolving current ot' pure air for breathing, withoutthe least perceptible draught, and not in sufficient volume to cause any chilling or danger to perfect health.
Figure l is a front view of my invention.
The drawing shows the invention as applied to the window, and the dotted lines indicate au extended view of the same. It consists of two narrow strips of sheet metal, A and B, shown in the dotted lines in an ogee-shaped form, bending out from the window, opening, returning in a small circle nearly to the sash.
The strip A is lapped over the strip B, for shortening and lengthening the ventilator to the var 'ing widths of' windows.l
Figure 2 is an end view or vertical section of my invention.
C C are flanges, extending from the bottom, at and slightly beyond each end of the strips, and so arranged as to support the window at each side as it rests upon the flanges, and alsoto extend into the groovel in the v wilulow-ii'ame, so preventing the escape of' the apparatus from its upright place in and before the opening.
The` air is admitted at the opening indicated at C in fig. 2, passes on toward A, meets the resistance of the curved strips A and B, revolves toward B, as described in iig. 2', and is deilected by the window-pane into the upper and middle portion ot the car, above the passengers, substantially as described.
That I claim, and desire to secure by Lett-ers Patent, is-
An ogee strip or mo'lding placed opposite the opening at the bot-torn of' a car-window, to check the inilowing current, and give it anupward and rotating motion, substantially as and for the purpose setforth.
Also, the ilanges C C, in combination with the window-groove or frame, to enable me to make aportable ventilator forcars.
Also, the combination of tle two narrow strips of the sheet metal, together with the flanges C C, as and for the purpose set t'orth.
