THOMAS L. MERRILL, OF OAKLAND, GALIFORNIA.

CAR-VENTILATOR.

SPECIFICATION forming part of Letters Patent No. 516,058, dated Miarch 6, 1894-.. Application filed Octohei` 6, 1893. Serie-l No. 487,359. (No model.)

T all whom, it may concern:

Be it known that I, THOMAS L. MERRILL, a citizen of the United States, residing in the city of Oakland, county of Alameda, State of California, have invented an Improvement in Oar-Ventilators; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to that class of ventilators, especially adapted for cars and other moving vehicles, and in which a rotary fan, driven by the exterior air currents', is employed, to exhaust the foul air from the car or vehicle.

My invention consists in a casing having a passage through its lower portion from end to end, and an opening in the upper portion of its inner side, exposed to or in communii cation with the interior of the car, and a fan mounted in said casing, and exposed at its lower portion to the current of air which passes through the bottom passage of the casing, whereby said fan is rotated, and the foul air from the interior of the car is thereby sucked out or exhausted through the side opening of the casing and discharged by the fan through the bottom passage.

The object of my invention is to provide a simple and efiective automatic device for withdrawing the foul air from cars and other moving vehicles.

Referring to the accompanying drawings for a more complete explanation of my invention,--Figure 1 is a perspective view of my ventilator. Fig. 2 is a longitudinal section of same. Fig. 3 is a view showing its application to the turret roof of a car. Fig. 4: shows its application to a Window sash. Fig. 5 shows its application on top of a car roof.

A is a casing, having in its lcwer portion, a passage o. extending from end to end and opening at each end to the exterior air. Upon the side of the casing in its upper portion is an opening a' of any suitable dimensions, here shown as about one-half of the side.

B is a rotary fan mounted suitably in the casing. Its blades, as will be seen, are exposed fully to and play by the side opening a' and they extend down into the bottom passage a and are thereby exposed to the current of air which passes through said bottom passage.

This device is intended to be located in any suitable position on the car or other vehicle, said position being such that its side opening a' shall be exposed to or in communication with the interior of the car, and its bottom passage shall be exposed to lthe outer air and lie in the plane of direction of travel, Whereby the current of air created by the suction of the car shall pass frecly through said bottom passage. As applied to cars, I have herein shown it located in three different positions, in any one or more of which it may be used. Thus, in Fig. 3 it is shown against the outer wall of the hood or turret roof at a point between the ordinary transorns c. The side opening a' is exposed through an opening in the hood wall, to the interior of the car, and this communication may be properly guarded by a screen or grating c'. In Fig. 4 I have shown it placed on the window-sill d' of the sash D, an opening, properly screened or guarded, being made through the sash rail and in communication with the side opening of the casing. In this position it will ventilate the car or the particular berth or section to which it is applied, without having to lift the sash at all. In Fig. 5 I have shown it applied directly to the top of the car roof E, in which case a hood a2 formed with or attached to the casing Aconnects its side opening o' with an opening in the car roof. It will be seen, that in Whichever direction the car moves, the exterior air, in rushing through the bottom passage a, will rotate the fan, and this movement of the fan will draw out the foul air from within the car through the side opening af, into the casing, from which it will then be discharged by the fan through the bottom passage.

'ioo

suction fan or fans operated by the exterior air current, to exhaustthe foul air from the interior of a car, and I do not claim such broadly as my invention, but

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

1. A ventilator for cars and other moving vehicles consisting of a casing, having a passage in its lower portion extending through it from end to end, with both ends open and having also an opening in the upper portion of one of its sides, and communicating with the car or vehicle interior, and a rotary fan in said casing, the blades of which extend down into the bottom passage and are exposed to the current of air passing through said passage whereby said fan is rotated, substantially as herein described.

2. A ventilator for cars and other moving vehicles, consisting of a casing, having a pas- Sage in its iower portion extending through it from end to end, with both ends open and having also an opening in the upper portion of one of its sides and communicating With the car or vehicle interior, and a rotary fan in said casing, the blades of which extend up beside and are exposed to the side opening of the casing, and also extend down into the bottom passage, and are exposed to the current of air passing through said passage whereby said fan is rotated, snbstantially as herein described.

In Witness whereof I have herennto set my hand.
