Application tiled November I '0 all whom it may concern Be it known that l. l lnwann Pl. lines, a citizen oi the United lltates, residing at New llrleans, in the parish olf Urleans and State of Louisiana, have invented new and useful improvements in Ventilators, of which the following is a specification.

My invention pertains to ventilators for cars, more especially refrigerator cars; and it consists in a peculiarly constructed and practically advantageous adjustable ventilator, designed more particularly :tor use on the body oi? the retrigeratmcar constituting the subject oil my contemporary application, filed. September 18, 1915, tlerial l lumber 51,4t25.

The present invention will be 'liully understood from the following description and claim when the some are read in connection with the drawings, acconuoanying and forming part of this s iecification, in. which:

Figure l is a side elevation showing my novel ventilator as properly applied and with the hood in its operative position.

ll ig. 2 is a longitudinal, vertical section of the same.

Fig. 3 is a top plan view illustrating the hood as thrown back to uncover the opening that it normally controls.

tiiinilar numerals of reference designate corresponding parts in all of the views of the drawings.

The car body 1 is provided in its top wall with an opening; 2., bordered by an upstand ing flange 3, but otherwise the said body may be of any desired construction and type Without attecting my present invention.

Hinged at 4: to the body 1 is the bass of the ventilator; the said base being oil? angular :Form in vertical section so as to con tain a rectangular frame 6 which is provided at its underside with a gasket 7, designed to bear on the metallic lining 8 of the opening- 2 and thereby render the closure air tight when. the ventilator is closed. lhe frame 6 is secured in the frame in any approved man ner, and it serves, in turn, to hold the flange 9 ol the ventilator hood 10 against the horizontallywlisposed portion of the base 5 with a view to strongly connecting the said. hood with the base.

ilny suitable means may be employed :lfor detachably fastening" the ventilator in. its working position; the fastener 11 being shown by Way ott eirample as a type that is adapted to be used in combination with a specification of letters Fatcnt.

i, padlock so as to prevent an unauthorized person entering the car through the open ing ili'; shown in l igs. 2 and 3, the hood 10 is provided with a front wa l, the upper portion oit' which and the top oil the hood descril .2 a part ol? a circle, as 'iuditaited by 19. In the said circular wall is formed an opening 13, which is controlled by guard l-il, oil: reticulated material, tired to the wall 12 and curred in conitoirlnity thereto. i-lt opposite sides of the opening and immediately in trout oi? the pain rd it are guides 15 which describe a part of a circle, as clearly shown in l ig. 2. lllovable in the said guides 15 is a curvilinear impcritoL'ate closure plate lll which when closed manifestly adapted to prevent the passage of air through the guarded opening it curvilinear perto- J. rated ha r 17 is lined to i the trout ol the hood 10 above and below the opening 13, and on the trout oil? the lower portitui oi the closure plate 16 is lined a bifurcated arm ltl, which receives and is movable Freely on the bar ll. The said aria 153 is provided with tr- 'isversc apertures 19 designed to be registered with the apertures of the bar it so as to receive a Fastening pin 20 that is connected with the arm 18 through the medium olf a chain 21. By virtue of this provision it is n'ut'uijliest the closure plate 16 may be closed to a greater or less extent, according to the volume of air it is desired to let into the car; also, that the said closure plate maybe ad justabl y lined in the DOSllllOl'l in which it is placed.

lln the hood is a handle 29;, through the medium ot which the hood may, when unfastoned, be swungbaclnvardly and down wardly into the position shown in l 3 so as to leave the opening; 2 entirely uncovered. From this it Follows that the opening 2 may be utilized for the eonvei'iient placing of ice or any other substance desired in the car body.

lt will be gathered from the tlioregoingr that my novel ventilator is easily adjusted and is highly e'tlicieut tor the purposes ascribed to it; also, that the ventilator is well adapted to withstand the rough usz'ige to which car appurtenances are ordinarily subjected.

ll-laving described my invention, What I claim and desire to secure by letters Pat out, is:

The combination of a body having an opening in its top wall and an upstanding:

llllli lllltl flange bordering said opening, and a ventiside a gasket opposed to the upper end of lator comprising a base and a hood having said upstanding flange of the body.

an opening and means for controlling said In testimony whereof I have hereunto set opening; the said base being of angular form my hand in presence of two subscribing wil- 5 in vertical section and hinged to the body nesses.

in position to receive said upstanding flange,

and the hood having a flange disposed under B SH the horizontal portion of the base, and a Vitnesses: v frame secured in the base and opposed to the R. G. EUs'rIs, l0 flange of the hood and having at its under M. E. KNIGHT.
