' To all whom it may concern:

Be it known that I, HERMAN Pnms, a citizen of the United States, and resident of.

Michigan City, county of Laporte, and State of Indiana, have invented certain new and useful Improvements in Refrigerator-Cars, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof. The invention relat to means for effect ing the drainage of the ice tanks of refrigerator cars; its object being to provide a valve controlled drainage out et so arranged that the cover to the .tank can be applied to its seat only when the valve is closed V The practice heretofore prevailing has been to permit the free discharge of water from the tankswhen a certain level has been reached by the melting of the ice. As a consequence there has been a continuous dripping of the salt-impregnated water in transit, to the detriment of the track and its appurtenances.

. By the IHtI'OdHCfiOH Of a cock inthe drainage outlet and the arrangement of its handle as now proposed, the drainage will occur i only when the tank is opened and the valve turned. This will ordinarily be done only in connection with the icing of the tank, and consequently at a place where the water discharge can be conveniently conveyed away 5 without detriment to the track.

' tank.

' The invention further prevents carelessness' on the part of employees, compelling them to close the valve before sealing the 'ith these objects in viewtheinvention consists in a structure such as is hereinafter described and illustrated in the accompanyin drawings, in which the valve stem is of en cient length to project above the top of the tank and's jointed to permit the upper end to be folded to lie below the tank cover,

. the extension above the joint, however, be-

ing of such length with reference to the width ofthe. tank that it can not be folded to horizontal position except when the valve is closed. 7

In the drawings-Figurc 1 is a detail transverse section of a car through the ice tanks; Fig. 2 is adetail plan viewof' a portion of the car showing the tops of the ice tanks; Fig. '3 is a the valve stem and Fig. 4 is a plan section of the drainage cock.

The body of the car is represented at 10,

detail perspective view of and there is shown two pairs of ice tanks 11, 12, and 13, 14, arranged transversely of the car. -The tanks of each pair are spaced apart, as shown, and are connectedby a drainage pipe 15, having a discharge nipple 16 within which is located a two-way valve 17.. The stem 18 ofthe valve extends upwardlyiabove the top of the car, and is jointed, as shown at 19, at the top of the tanks and below the level both tanks of the-pair.

That portion 21 of the valve stem which is above the joint 19 is of-such length and is so disposed that it cannot be foldedrdown valve is closed. T his'is acrel'atively so positioning the tend beyond the cover seat, thereby prevent-.

ing the adjustment of the c'mter, but when folded longitudinally of the tank it will not reach to the end of the cover seat. Furthermore, grip piece 22 or 23, which is so directed that it lies in horizontal position when the stem of the lid 20 which'covers to horizontal position below the lid'20 ex that the joint19'of the latthe stem is provided with a handle or is folded down only when the valve is closed.

This disposition of the handle or grip member would effectively prevent the placing of the cover even if the '11 per section of the stem were so short that .it' would fold below the cover seat when transverse of the tank. This form of grip member has the further advantage that when the cover is opened it forms an obstruction to the entrance of-ice until raised, thereby calling the attention of the attendant to cock is not open. Either form of grip member, that shown at 22, which'consists of a cross-bar. at the upper end of the' stem, or thatshown. at 23, which is a mere lateral projection of the stem in one direction, may be used. 5 Ilclaim as my invention- 1. In a car,. in combination, an icetank having an oblong opening at its top, a-lid for covering such opening, a drain cock for the tank, a stem above the tank and being jointed below the cover seat, the lengthof the stem above the joint being greater than the distance from the joint to the side. of the tank opening the fact that-the drain and less than the distance from the joint to the end of the tank opening, the valveand stem being so related that the valve is closed when the stem folds lengthwise of the tank opening. 7

2. In a car, in combination, an ice tank, a cover therefor, a drain cock for the tank,

p a jointed stem for the drain cock, such stem extending above the cover seat, its upper end being adapted to fold below the cover seat only "when the drain cock is closed.

3. In a car, in combination, an ice tank having an oblong opening at its top, a lid for covering such opening, a drain cock for the tank, a stem for above the tank and being jointed below the cover seat, the length of the stem above the joint being greater than the distance from the joint to the side of the tank opening the cock extending inoaeee and less than the distance from the joint to the end of the tank opening, the valve and stem being so related that the valve is closed when the stem folds lengthwise of the tank opening, the stem havin a laterally projecting grip-piece so disposed that it is transverse to the tank opening when the valve is closed.

4. In a car, in combination, a tank, a

cover for the tank, a drain cock for the JNo. W. ConLsoN, W 40. Roemson.
