U iTnn STATES PATENT OFFICEO HENRY E. J AOOBS, OF FOND DU LAO, \VISGONSIN.

VENTILATOR FOR CARS.

SPECIFICATION forming part of Letters Patent No. 363,642, dated May,,2.4, 1887.

Application filed July 26, 1886. Serial No. 209,058. (No model.)

To all whom it may concern:

Be it known that I, HENRY E. JACOBS, a citizen of the United States, residing at Fond du Lac, in the county of Fond du Lac and State of \Visconsin, have inventeda certain new and Improved Ventilator for Gar-Vindows; and I hereby declare the following to be a full, clear, and exact description of the same.

My improvement relates to the class of ventilators used on railroad passengercars to exhaust the impure air from within the cars by the action of the current of external air, produced principally by the movement of the train, through a tube crossing an opening leading into the car, to draw therefrom the vitiated atmosphere by suction.

It is my object to provide a simple and inexpensive device for the purpose for application at the car-windows, and which shall be readily adjustable when required and as easily removed when not required.

To this end my invention consists in the genera], as well as in the specific,- construction of my improved ventilator, all as hereinafter fully set forth and claimed.

In the drawings, Figure 1 shows the exter nal window portion of a railroad passengercar provided with my improved ventilator; Fig. 2, a section of the same taken on the line 2 2 of Fig. 1 and viewed in the direction of the arrow; and Fig. 3, a similar view taken on the line 3 3 of Fig. 1 and viewed in the direction of the arrows.

A is aboard or plate of a length to cause it to fit snugly between the sides of the sash of a car-window, B, and of any desired width, but preferably only sufficiently wide to carry on one surface the mechanism hereinafter described and to be admitted into the windowsash on raising the window part way, though higher than the width ofthe board, against the upper edge of which the window is lowered or supported. The board is provided with an opening, 0, preferably in the form of a longitudinal slot, as shown, covered on one surface by a shield or split tube, D, secured at its edges to the board and open at one end.

E is a tube within the shield D, extending lengthwise of the board across the opening 0 therein, slightly beyond one edge of the latter at one end, and flaring toward its opposite end, which extends beyond the shield D, closed around it at the extremity farthest from the edge of the opening C adjacent to the cylindrical end of the tube E.

The device is readily adjusted within the sash of a carwindow, to cause the parts D and E to be outside and lengthwise of the car upon raising the window for the purpose, and cansing it to have contact at its lower edge with the upper edge of the board A, to avoid an unpressed in its passage, and by its expansion on discharging at the cylindrical end of the tube D increases the suction-force which operates to exhaust impure air from the interior of the car, and thus ventilate it.

The device affords particular advantage in sleeping-cars for ventilating the sleeping-compartments, sinceit operates without producing any cold draft, and may thus be used while a compartment is occupied without inconvenience or injurious consequences to the occu pant, and notwithstanding the absence of a screen as part of the device no objectionable matter can enter the car through the ventilator, owing to the construction and manner of its action.

What I claim as new, and desire to secure by Letters Patent, is-

1. A removable car-window ventilator, comprising, in combination, a board or plate, A, having a shielded opening, 0, and a tube, E, flaring toward one end, upon one side of the board A, and extending across the opening 0, substantially as and for the purpose set forth.

2. A removable car window ventilator,

comprising, in combination, a board or plate, A, having an opening, 0, a shield, D, secured upon one side of the part A to cover the opening therein and open at one end, and a tube, 5 E, extending across the opening 0, within the shield D, and flaring toward one end, which extends beyond the corresponding end of the shield, the whole being constructed and arranged to operate substantially as described.
