UNITED STATES 1,582,894 PATENT OFFICE.
GEORGE W. BENDER, OF CHICAGO, ILLINOIEi, ASSIGNOR TO MUDGE & COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.
VENTILATOB.
Original application filed September To all whom it may concern: Be it known that I, Gsoncn IV. BENDER,
, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Ventilators, of which the following is a specification.
My invention relates to ventilators for railway cars or the like, of the type in which ventilation is induced by suction created by the impact of the air on a surface arranged at right angles to the direction of movement of the car. ,1 A
It is one of the objects of my invention to provide a new and improved form and arrangement of parts by which an nnprovcJ I I Operation may result.
Specifically it is one of the objects of my invention to arrange a mechanically operated suction deviceadapted to cooperate effectively'with the, ventilator when the car is at rest.
Other objects of my invention will ap car hereinafter.
The preferred means by which I have accomplished my several objects are illustrated in the accompanying drawing and are hereinafter specifically described.
That Which-I believe to be new and desire to cover by this application is set forth in the cl. ims.
In t 'e drawing Fig. 1 is a transverse sectional view through a portion of a car equipped with my improved mechanism.
F ig. 2 is a horizontal sectional view taken on line 22 of'Fig. 1.
Fig. 3 is a fragmentary, horizontal sectional view, taken on line 3-'3 of F ig. 1.
Referring to the drawing, 10 indicates the upper deck, and 11 the lower deck of the clerc-story of a car equipped with my llXlproved ventilating mechanism of the general type illustrated in my copcnding application Serial No. 408,219, filed September 4, 1920, of which this application is a division, such prior application having resulted in Patent No. 1,469,577, dated October 2. 1923.
This mechanism comprises a centrifugal fan of any approved type through the body of which air is free to sweep when the fan at rest In the construction shown the cos es a casing 12 supported by a 4, 1920, Serial Nd. 408,219. Divided and H11: annlication filed Kay 18, 1923. Serial No. 639,725.
standard 13 from a hanger 14 depending from the upper deck 10. The rotary member of the fan comprises a plate 15 fixedly mounted on a shaft 16 so as to be rotated thereb A plurality of lates 17 are arrangec in spaced relation etwcen the plate 15 and-the ring '18, the arran ement being such that upon the rotation o the shaft in a clockwise direction in Fig. 1, air is drawn in through the opening 19 in the face of the casing and forced from the casing through the plpe 20 as will be readily understood.
It will be appreciated that when the fan is at rest, there is nothing to prevent the free movement of air through the casin 12. Upon the outer end of the pipe 20 I lavesecured a transversely extending pipe 21 having a fiange'22 at its outer end to which the ventilator is secured in any suitable manner. As will appear from Figs. 1 and 2, the venti- .lator comprises side plates 23 and 24;, con
nected together in spaced relation by plates 25 and 26 which actas the air ramming faces. Between the plates 25 and26, the plates 23 and 24 are connected by means of two transverse plates 27 and 28, which are diagonally disposed so as to converge toward their lower edges, being spaced apart and spaced from the air ramming faces 25 and 26. The plates 23 and 24 are also connected by means of two transverse plates 29' in position above the plates 27 and 28, only one of the plates 29 being shown. The plates 29 are also diagonally disposed, being arranged so as to converge toward their upper edges. Each of the plates 27, 28 and 29 is provided on its outer edge with an outwardly directed flange 29, as is best shown in Fig. 3. Longitudinally extending plates 30 and 31 are mounted in spaced relation on the transverse plates 27 and 28, and longitudinally extending plates 32 and 33 similarly spaced are mounted on the transverse plates 29. The side plate 23 is pro ill able source of power, serving to drive the fan for carrying the air from the car through the ventilating device, the air so driven out finding ready escape between the plates 40. When the car is in motion, however, the shaft 16 is to be at rest, whereupon the impact of the air upon the air ramming face 2-5 or 26 and the sweep of the air over the edges of such ilates induce a stream of air. to flow outwar ly through the ventilator in the now well understood manner. The sweep of the air past the outer edge of one of the plates 38.:1I1Cl 39 which is in advance in the movement of the car, assists in the production of the induced current outwardly through the ventilator.
While I prefer to embody my invention in the form illustrated in the drawing, it will be understood that I do not wish to be restricted to the particular form shown, except so far as the same is specifically claimed, it being evident that various changes can he made in the form of structure without departing from the spirit ofthe invention.
1 claim: a 1. A Y hollow substantially rectangular bmclike ventilator for railway cars having an ail-inlet passage in one face, the opposite l'ace being substantially open, a plurality of spaced slanting plates extending across said open face, air ramming faces disposed transversely to the direction of move ment of the car, there being exhaust passages in the remaining two faces of the ventilator, and spaced oppositely inclined plates in each of the exhaust passa es disposed transversely to the air current eflected over being arranged substantially in the planes passing throu hthe opposite edges of the air ramming aces.
2. A hollow substantially rectangular boxlike ventilator for'railway cars having an air inlet in one side face, the opposite side face being substantially open, a plurality of downwardly slanted plates extending across said open sideface, air ramming side.
plate, the outer edges of such plates being arranged substantially in the planes passing through the opposite edges of the air rainming faces.
3. A hollow box-like ventilator for rail way cars having an opening in its outer side face and having a plurality of downn'ardly slanted plates extending horizontally across said opening, said ventilator comprising a-ir ramming faces disposed transversely to the direction of movement of the car, with exhaust passages adjacent to said air ramming faces, spaced oppositely inclined plates in each of the exhaust passages. disposed transversely to the air current deflected over said passages, the outer edges of said plates being arranged substantially in the planes passing through the opposite edges of the-air ramming faces, and an exhaust fan connected with said structure and adapted to force a stream'of air "outwardly through the open side face and said passages, the outer edges of said plates adapted to permit the free passage of air I therethrough when not in operation.
