TRAIN-PIPE VALVE.

Specification of Letters Patent. Patented 13 1918 Application filed December 21,1917. Serial Not 308,316.

To all whom it may concern:

Be it knownthat I, EDWARD E. GOLD, a citizen of the United States of America, residing in the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Train-Pipe Valves, of which the following is a specification. i

This invention relates to an end valve for train-pipes in railway car heating systems, the purpose of such valves being to close off the train-pipe at the rear of the last car of the train.

My invention relates to train-pipe valves of the type comprising a shell or valve casing adapted for connection to the train-pipe and having an internal ,seat' and a plunger movable in the shell to close against such.

seat in one position, or in its opposite position to be withdrawn therefrom to leave a clear way through the valve. When such valves are used as end train-pipe valves the seat communicates with an outlet passage adapted for connection to the nipple carrying the steam coupled hose. Such end valves are sometimes provided with a restricted drip outlet or bleeder port for blowing off steam and condensation from the rear of the train-pipe, such orifice being closed when the main valve is open, andvice versa.

vTrain-pipe valves of the character described are set forth in the following prior patents granted to me, upon which the present invention constitutes a further improvement: I

7 No. 498,545, of May 3, 1893' No. 585,383, of June 29, 189 7;

No. 756,492, of April 5, 1904;

N 0. 806,970, of December 12, 1905.

Such train-pipe valves have been sometimes applied at the middle of the car where.

the branch pipes lead-from the train-pipe to enter the car; and in'other cases have been applied at the ends of the train-pipe where it connects with the hose.

The present invention is; designed to improve the construction of the train-pipe valve to facilitate getting access to the internal plunger and its removal forrepacking, and to provide a convenient construction of adjustable drip outlet orobleeder. Formerly itiwas necessary, in order to remove the plunger, to take off a cap closing thetop of the valve shell, and after lifting outthe plungerroperating stem to then lift the plunger out the top opening;

or else to disconnecttthepipe-or hose connection, or, other words, to. remove the train-pipe valve from its connection-with the pipe or fittings onone or both'ends and then withdraw the plunger throughthe end opening thus provided. According to the presentinvention the plunger, instead of moving in line with the steam pipe, moves in a plunger chamber'which is out of'line therewith and preferably transverse there to, and the shell has an opening inline with the plunger sufliciently large to withdraw the plungerendwise through such opening, acap being provided for closing the opening when. the plunger is. in place.- This cap is utilized to form a seat against which the plunger seats when the valve is wide open, whereby to shut off communication between the interior of the shell and a drip outlet or bleeder orifice which'is most conveniently applied to such cap. For adjusting the outblow through thisbleeder orifice in the valve at the end of'th'e train, an adjusting screw forminga needle valve is provided. valve shell is formedwith an outlet beyond its normal seat which is curvedlaterally or downwardly andterminates preferably in an oblique connection for the direct, attachment thereto of the hose nipple, thus avoiding the necessity of interposing'a skewed outlet elbow such as has heretofore been commonly used,

. The preferred embodiment of the inventionv is shown in the accompanying drawings, in which-, 1 e
