WELL TRAP DRAIN FOR REFRIGERATOR CARS Filed April 21, 1937 Y a wdzdzarze,

Patented Mar. 15, 1938 UNITED STATES 2,110,927 WELL TRAP DRAIN FOR REFRIGERATOR CARS Edward Zane, Chicago, Ill., assignor to Union Railway Equipment Company, Chicago, 111., a corporation of South Dakota Application April 21, 1937, Serial No. 138,170

Claims.

The trap of the present invention is secured to the under side of the car floor in position to coact with the down spout of a drip pan on the interior of the car, and to provide a water seal 5 within the trap which serves to prevent the ingress of air to the interior of the car. The drip is so constructed as to maintain itself in normal sealing position but is adapted to be easily'tilted to discharge the water therefrom when it is desired to clean out the spout or bowl, 'or as occasion may require; and the device is so constructed as to accommodate itself. to carsirrespective of variations in the thickness of the floor without impairment of the sealing functions of the device.

Further objects and details of the invention will appear from a description thereof in conjunction with the accompanying drawing,where- Figure 1 is a sectional elevation of the well trap drain of the present invention secured to the bottom of a refrigerator car or the like; i

Fig. 2 is a sectional view taken on line 2-2 of Fig. 1; and

Fig. 3 is a side elevation of the device.

The well trap comprises a bowl ID of circular cup-shaped formation provided on its outer upper margin with an outwardly extending sloping drain spout I I having side walls I2 which at their inner ends merge into the curved side walls of the bowl. The bowl on its inner side has secured thereto a counterweight of which abuts against the curving wall of the bowl, and the counterweight is provided with forwardly extending lugs l5 which bear against the side walls of the bowl and are secured thereto by bolts l6 entered through upper and lower lugs ll outstanding from the wall of the bowl, or in any other suitable manner.

Above the counterweight the wall of the bowl on its rear edge is provided with an elevated, overhanging, inturned flange 18 having formed thereon a pair of spaced lugs I9 which extend forwardly and pivot upon a pintle 20 which is entered through ears 2| inwardly projecting from the wall of a cylindrical hood 22, the lower end of which enters the bowl, and which above its lower end is provided with a flat skirt 23 which seats upon the upper marginof the bowl and underlies the overhanging flange l8 which is held against it by the counterweight when the bowl is elevated. The upper end 24 of the hood is of enlarged diameter and provided with radially extending lugs 25 which are secured to the bottom 26 of a car by means of bolts 21 or equivalent attaching means. T e o o the car is bored IS, the inner face It to receive a down spout 28, the upper end of which communicates with a drain aperture in the floorof a drip pan 29 on the interior of the car, and the lower end of which enters the enlarged upper end 24 of the hood. 5

The arrangement is one which affords a well or pocket surrounding the lower end of the hood 22, so that, as drainage accumulates in the bowl, .it will rise above the lower end of the hood and thus constitute a water seal against the inflow of air tothe interior of the car, which is important, in the case of refrigerator cars, in order to maintain the desired low temperatures therein. The elevation of the inner end of the drain'spout l l is such as to afford a sufiiciently deep seal for l ,the hood, and at the same time to permit the ready discharge by overflow of water accumulating within the drain trap.

The provision of the counterweight serves to maintain the bowl in its normal or elevated re- 20 lation, but when itis desired to empty the bowl for cleaning, or otherwise, the bowl will be tilted to the dotted line position, which permits the interior to be easily cleaned and also affords uninterrupted access to the lower end of the hood to 25 facilitate the cleaning thereof. As soon as the bowl is released from the open position, it will swing back to scaling position and thus maintain itself with its upper margin in sealing contact with the skirted rim of the hood.

The present invention is one which may be very easily secured to refrigerator cars of any standard construction, and of any depth or thickness of floor, since it merely requires the drilling of a hole through the floor for the purpose of 35 locating the down spout, which telescopes into the upper end of the hood irrespective of the thickness of the floor; and since the remainder of the structure is secured exteriorly of the car, no further cutting of the car floor is required in flt- 40 ting the well trap drain in position. By employing a bowl and hood which constitute a selfcontained unit, the depth of the seal will be maintained constant regardless of the depth to which the down spout projects into the bowl, so that 45 the seal thus afforded can be fitted to any car regardless of the floor thickness.

Furthermore, the location of the device exteriorly of the car greatly facilitates the cleaning operation from the outside of the car, wheth- 50 er the car be loaded or empty, which involves a decided advantage in comparison with structures which are only accessible from the interior of the car.

Although the invention has been described 55 with particularity as to detail, it is not the intention to limit the same to exactly the form shown, since modifications therein may be made without departing from the spirit of the invention.

I claim:

1. In combination with a down spout for refrigerator cars or the like, a hood into the upper end of which the down spout projects, a bowl surrounding the lower end of the hood and normally adapted to afiord a water seal therefor, a skirt outwardly projecting fromthe hood above its lower end and adapted when the bowl stands elevated to abut against the upper margin thereof to aiford a closure for the bowl, and a drain spout for the bowl located above the lower end of the hood to maintain a water seal.

2. In combination with a down spout for refrigerator cars or the like, a hood into the upper end of which the down spout projects, a bowl surrounding the lower end of the hood and normally adapted to afiord a water seal therefor, a skirt outwardly projecting from the hood above its lower end and adapted when the bowl stands elevated to abut against the upper margin thereof to afford a closure for the bowl, a drain spout for the bowl located above the lower end of the hood to maintain a water seal, and means forhinging the bowl to the hood to bowl to be tilted downwardly.

3. In combination with a down spout for refrigerator cars or the like, a hood into the upper end of which the down spout projects, a bowl surrounding the lower end of the hood and normally adapted to afford a water seal therefor, a skirt outwardly projecting from the hood above its lower end and adapted when the bowl stands elevated to abut against the upper margin thereof to afford a closure for the bowl, a drain spout for the bowl located above the lower end of the hood to maintain a Water seal, means for hinging the bowl to the hood to permit the bowl to permit the bowl hingedly secured to the hood in position to bring the lower end of the hood within the confines of the bowl, a drain spout laterally projecting from the bowl at proper elevation to normally maintain a water seal around the lower end of the hood, a skirt outwardly projecting from'the hood and adapted when, the bowl is elevated to afford an abutment against which the upper margin of the bowl, contacts to close the bowl and a counterweight on the bowl for normally holding the bowl in elevated relation and permitting the bowl to be tilted to afford access to the interior thereof.

5. In combination with a down spout for refrigerator cars or the like, a self-contained unit comprising a cylindrical hood and means for securing the hood to the floor of a car in position to receive the lower end .of the down spout, a bowl hinge-dly secured to the hood in position to bring the lower end of the hood within the confines of the bowl, an inturned overhanging flange along the rear upper margin of the bowl, a skirt outwardly projecting from the hood in position to normally underlie the overhanging flange and overlie and abut against the upper margin of the bowl, a drain spout laterally projecting from the bowl at proper elevation to normally maintain a water seal around the lower end of the hood, and a counterweight secured to the bowl in position to normally hold the drain spout elevated and to hold the bowl in contacting relation with the skirt to maintain the water seal.
