WINDOW-VENTILATOR.

Specification of Letters Patent.

Patented July 13, 1915.

Application filed August 14, 1911. Serial No. 643,831.

' lators, of which the following is a specification.

My invention relates to ventilators for windows and is more particularly designed for car windows, although it may be used in residences and other buildings.

My object has been to produce a vent lator for the purpose described which is simple and economical, to manufacture.

I have endeavored to produce a ventilator which may be placed in position and ad usted with the utmost facility to give the desired air currents in different directions.

Other objects and advantages will become apparent in the following specification when taken in connection with the accompanying drawings, in which Figure 1 is a general view of a portion of the interior of a car with my ventilators ap-. plied to two of the windows therein.- Fig. 2 is a perspective view of one of the ventilators showing the shutters adjusted to de flect the air currents upwardly and downwardly. Fig. 3 is a perspective view of the same with one of the shutters closed and another disposed in a vertical position spaced from the ventilator frame. Fig. 4 is a sectional view taken substantially along the line 1, 4 of Fig. 2. Fig. 5 is a sectional view taken along the line 5,5 of Fig. 2.

. Fig. 6 is a sectional view taken along the

line

6, 6 of Fig. 3. Fig. 7 is a sectional view taken along the line 7, 7 of Fig. 3. Fig. 8 is an elevation of one end of the ventilator with portions broken away.

In Fig. 1 of the drawings two of my ventilators are shown in place and are designated by the reference numeral 10. I preferably make the ventilator in two sections hinged together, but they may be made in the form of single independent sections.

These sections each comprise a main frame 11 inclosing an opening or air passage. A wire screen or netting 12 is attached to said frame and held in place by the chat 13. A shutter comprising a frame 14: and sheet of glass 15 is adapted to close the said opening. When closed this shutter lies within the frame member 16, which is fixed to the main frame 11. This member 16 may be considered an extension of the main frame and incloses the shutter on three sides, the bottom being left open. The open space appears at 16 in the figures. The shutter is movably attached-to this frame by means of a double link or yoke 17 which is adapted to inclose substantially half of the periphery of the shutter. This yoke is pivotally attached at its ends by pins 18 at substantially the middle of the width of the shutter at its ends. The yoke comprises a body portion 17 and downwardly bent ends 17% Trunnions 19 are provided at the corners of the yoke and are preferably integral therewith, these trunnions being adapted to slide in slots 20 in the vertical members 16 of the main frame. These slots 20 are at the upper ends of the members 16 and are of such length as to permit a sliding movement of suflicient extent to permit the shutter to swing outwardly to the position shown in Fig. 4:. The horizontal member 16 of the frame is grooved or recessed as shown at 21 into which the body portion 17 of the yoke may partly or wholly enter when the shutter is closed as shown in Fig. 6. The lower portion 22 of the shutter frame may be swung around to a position between the yoke 17 and the vertical portion 24: of the frame. The edge of the shutter is beveled as shown in 23 to provide a bearing surface at the point of contact with said frame. When the edge of the shutter is in this position the yoke 17 cannot close or swing downwardly to a vertical position and the shutter is thereby held in an inclined position. In this latter position the inclination is opposite to that shown in Fig. 4. By the simple expedient of reversing the shutter the angle of inclination can be reversed and the currents of air may be deflected downwardly instead of upwardly. At the lower edge of the main frame I provide a pivoted plate 25, which serves as a retaining device for the lower edge of the shutter. This plate also serves as a dust guard and prevents particles of dust or cinders entering the car around the lower edge of the shutter. The lower edge of the ventilator normally rests outside of a member of the window framing which forms a step or depression as shown at 25*. The member 25 consists preferably of a me tallic plate with ends 25 turned at right angles thereto. Pins 26 may be fitted as pivots in apertures in the said ends and fixed in the frame members 16. The dust guard be deflecteddownwa'rdly by or plate 25 may therefore accommodate any angular position of the shutter. It may also lie sidewise against it when the shutter is closed as shown in Fig. 6. An upturned edge 27 serves to support the shutter in proper relation to said plate. The weight of the shutter is supported by this edge and causes the upper portion 25 of the plate to bear snugly againstthe lower portion 22 of the shutter frame, thus causing a weatherproof joint to be produced.

It will be seen that in using my ventilator, it can be inserted in place in the window with the utmost facility, and that the incoming air may be deflected upwardly by simply opening the shutter. The air may reversing the shutter and causing it to close as far as the yoke permits. The shutter may also be placed in a verticahposition with its lower edge resting upon the window casing as shown in Fig. 7 The currents may be deflected in a variety of directions as shown in Figs. 2 and 3. My improved ventilator is also very effective as a dust guard and particles of dust that enter the ventilator through the screen will be caught by it. When the deflector occupies'a position to deflect air currents upwardly as shown in Fig. 1, the particles of dust or cinders that strike the shutter will slide downwardly and finally lodge between the plate 25 and the main frame. Should any considerable amount of dust accumulate it can be allowed to escape by simply raising the whole ventilator frame.

While I have described more or less precisely the details of'construction, I do not wish to be understood as limiting myself thereto, as I contemplate changes in form and the proportion of parts and the substitution of equivalents as circumstances may suggest or render expedient without departing from the spirit of my invention.
