Figure 4 is a perspective of the device ing toward the interior face or side. igure 5 is a cross sectional view taken along the line 55 of Figure 3 and looking in the direction of the arrows there shown.
A'indicates a vehicle body of any desired construction, and B the partially lowered window,the space between the top edge of which and the top of the window frame being designed to be occupied by my improved ventilator. This consists essentially of a rectangular frame C, preferably of channeled cross-sectional form, as brought out in Figure 4. Slidably supported within this channel is a closure member F provided with a kno b G for convenient actuation, this closure piece being of approximately half the length of the ventilator as a whole. When in drawn back position, so that the ventilator is functioning to its full capacity, this .This invention relates to an improved venclosure Tam- OFFICE panel F lies in spaced parallel relation with the fixed panel E, which extends half of the length of the ventilator as about a whole.
The forward end of' this fixed panel E, which is located on the outside of the shell,
that is, on the outside of the c ably c urved slightly at the poin form the rear boundary of the .sp
by a series of incline which forward end of ar, is prefert H so as to ace occupied d vanes or battle members extend angularly outward from the the ventilator,
being supported at their top and bottom edges by the tapering border pieces J. The forward curved edges of the border pieces are s angular piece K the preferred as brought out particularly in 4, extends for a portion of it tically right angularly to th ventilator 'as a whole, sharply rearwardly.
and then Thus, as
space between the rearward edge ber K the sp is left between them of which plane of the and the slightly outbent ace between the open,
it will be noted, from an i panned by the form of which, Figures 3 and s length prace plane of the turns quite regards the of the memportion H,
bordering members J except for the spaced positiomng the vanes or baflie members,
nspection of are preferably placed angles relatively to the of the ventilator, beginning with a quite sharp angle as regards the positioning vane M near the curved portion H and approaching much more nearly a lar position as regards the slant N next adjacent the these vanes or baflles being of wind breake perpendicuof the vane r portion K,
progressively lesser breadth accordingly. When, however. it is desired to close the slide;
movin the the ou of the panel F by g it to the forward portion of the venter air the bottom or several vanes or bafiies.
rattling, I preferably provide a on the 0 which is curved suiiiciently to engage the inner edge of the 86V the closure panel is drawn therea The as foll n as regards nication with is negatived by the presence of .the slide across inner edges To prevent leaf spring uter side of the closure panel F,
frictionally ral baffles as cross.
ed device is end plate K plate swirls around and over p the vehicle being three or at the to" the'plane of the ventilator as a whole,
which latter in turn parallels the course of the vehicle, this end plate, receives the direct transverse impact of the wind, illustrated by the arrow W, as the vehicle travels along, though its outward extent of only about most four inches is negligible as regards wind resistance to the travel of the vehicle as a whole. The windjthus strikg ing the perpendicular portion'of this impact the curved outer edge thereof toward the rear or fixed vpanel E, leaving more or less of a vacuum immediately adjacent the outer edges of the several vanes or baflle plates, on something the same principle that the wing of an aeroplane is made more or less thick at its forward edge in order to benefit from the lifting influence of the partial vacuum created immediately above it by the corresponding initial and.
then deflected impact of the wind against its forward edge. The induced swirling of the air' about and over'the curved outer edge of this impact plate resultsinlthe air inside drawn outwardly between the several vanes by the vacuum condition thus created immediately adjacent their outer edges, as emphasized graphically by the several curved line arrows, X, Y and Z, shown in Figure 3, and ithas been .my experience from repeated severe tests of such a device that proportionately to the exposed air passage space as regulated by the position of the closure panel F a remarkable degree of outward draught is secured, and that this is materially aided and guided by the slightly progressive an ular inclination ofthe several baffles as they lie spacedly adjacent one another from front to rear. It will of course be obvious that the size of the exposed space between the vanes or I regulated as regards the actual outflow of air from the vehicle by the selective positioning of the slidable closure panel F It will thus be seen that, without resorting to the use of an external wall piece, whic with the main body of the ventilator woul serve as more or less of a funnel, I have produced an efficiently functioning ventilator mechanism, whereby an adequate quantity of bad air may hicle with a minimum of discomfort to the and angularity of the occupants, compensation for which' in the form of indrawn fresh air can be confidently looked for through the various incompletely closed cracks and apertures of the vehicle enclosure. Modifications as to the number vanes, as well .as the details of the frame and door or closure panel as such, can be indulged in without departure my invention, even to the degree of entirely omitting closure panel F if desired.
