VENTILATOR FOR REFRIGERATOR-CARS.
SPECIFICATION forming part of Letters Patent No. 585,779, dated July 6, 1897.
Application filed August 3, 1896. Serial No. 601,440. (No model.)
To all whom it may concern.-
Be it known that We, J ACOB NORLING and CHARLES E. J OHNSON, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Car- Ventilators, which is fully set forth in the following specification, reference being had to the accompanying drawings, in which- Figure 1 is a plan view of a portion of a car to which our ventilator is applied, showing the lid thrown open, but the ventilator back from the ice-aperture. Fig. 2 is a similar view with the ventilator over the aperture,but not raised. Fig. 3 is a vertical longitudinal section on the line 3 3 of Fig. 2. Fig. 4c is a similar section showing the ventilator raised. Fig. 5 is a vertical cross-section on the line 5 5 of Fig. 4 in the direction of the arrow. Fig. 6 is a detail plan view of a corner of the ice-aperture and ventilator-frame. Fig. 7 is an enlarged detail view of a portion of Fig. 3. Fig. 8 is an enlarged detail view of aportion of Fig. 4.
Our invention relates to ventilators particularly adapted for use in combined refrigerator and ventilated cars, and has for its ob ject to provide a structure less liable to injury and wear and more efficient in operation than the ventilators of this general type heretofore used.
Referring to the drawings by letterfA represents a portion of a car-roof which is provided with ice-apertures A in the usual Way. Surrounding each such aperture, upon three sides thereof, we construct a curb B, which is provided on its inner side with the horizontal rib b. Upon the two opposite sides of the curb B are secured strips B, provided on their inner sides with horizontal ribs 1), corresponding to the ribs 2), but located above the same. Between the two sets of ribs 11 and Z) there are thus formed the horizontal guides B adapted to receive the ventilatorframe, later described. Upon the front of the curb B is secured a strip B corresponding to the strips B, but without any rib b.
Upon the car-roof, immediately in rear of the ice-aperture, upon that side thereof not inelosed by the curb B, we construct a hood or box C, of approximately the same area as pose hereinafter described.
ice-aperture.
that of the ice-aperture, open upon the side adjacent to the aperture. Upon the vertical sides of the hood C, part way between the roof C of the hood and the roof A of the car, which forms the bottom of the hood, are secured horizontal strips 0 in prolongation of the strips b. There are thus formed between the said strips and the roof A of the car guides C in continuation of the guides B Upon the forward edge e of the roof *0 of the hood are provided two forwardly-projecting lugs 0 which extend outward so as'to nearly come in contact with the cover F when the latter is in its elevated position, for the pur- To the said edge 0 of the roof of the hood is hinged a lid D, adapted to swing down over and close the The lid D comprises the lid proper, D, and the reinforced portion D secured to the bottom thereof, provided with the beveled edges (1. This reinforcement is of the ordinary construction and serves for heat-insulating purposes.
Adjacent to the hinged edge of the lid D,
secured to the under side thereof, are provided the lugs or short arms 61, for an object later described. The free edge of the lid is provided with a hasp d adapted, when the lid is closed, to be looked upon the staple (Z secured to the roof of the car in front of the ice-aperture.
The ventilator itself comprises a horizontal frame, a cover hinged thereto, ascreen hinged to the free edge of the cover, and side wings hinged to the sides of the said cover. The frame E is rectangular and consists of front and rear pieces E and E and side pieces E and E all provided at their lower inner edge .with an inwardly-projecting rib or flange e.
The sides of the frame, E and E fit in the guides B and C so that the frame is adapted to be slid backward and forward from its poedge of the cover F is hinged a screen-frame G, provided withascreen G. The lower edge of the screen-frame is provided with a hasp 9, adapted to be locked to a staple g, mounted upon the forward edge E of the ventilatorframe. To the sides'of the cover F are hinged the triangular side pieces H H. Each of the said side pieces is provided on its lower edge with a lug h, adapted to fit, when the ventilator is raised into operative position, in the notch 77., formed in the rib c of the frame sides E E aforesaid.
To refer now to the operation of the parts the construction of which is hereinabove described, when the car is to be used as a ventilated car the lid D is thrown back and the ventilator is drawn forward into its position over the ice-aperture. The cover F is now raised. The screen-frame, screen, and side wings are swung down, the latter having the lugs h fitting in the apertures h of the ventilator-frame, and the former being locked by the hasp and staple g and g. Thus the Ventilator is locked in its raised position and cannot be lowered until unlocked. In such position it can obviously not be removed or shoved back from the ice-aperture, which is thus secured against intrusion. To prevent more completely the sliding backward of the whole ventilator, the lugs c are formed as above described and are adapted to bear against the lower or rear portion of the cover F, should the latter be pushed back when the same is raised.
When the car is to be used as a refrigerator-car, the ventilator is unlocked, the side wings H and the screen-frame G are swung up under the cover F, which is then lowered into horizontal position, as shown in Fig. 3, and the entire ventilator is slid back into the hood or housing 0. Thus it is entirely removed from the ice-aperture and secured from any injury during the icing of the car. The lid D is swung down over the ice-aperture and locked in such position by the hasp and staple d and (i The short arms or lugs d prevent the ventilator sliding forward over the ice-aperture while the lid is thus closed and hold the ventilator securely in its housed position.
Having thus described our invention, what we claim, and desire to secure by Letters Patent, is
1. In a car provided with an aperture A,
a lid D, adapted to close the same, a hood.
formed upon the car at one side of the said aperture, a movable frame adapted to slide from a position in the hood to a position over the aperture, a cover hinged to said frame, a screen hinged to the free edge of the cover, and triangular side wings hinged to the sides of the cover, said wings and screen being adapted to support the cover in an inclined position when the ventilator is in use, and to be folded down upon the frame and the whole slid back into the hood when not in use, substantially as described.
