CAB TURRET.

. Application filed November 29, 1922. Serial No. 603,930.

T 0 all whom it may concern.

Be it known that I, CHARLES M. BELL, of Schenectady, in the county of Schenectady and State of New York, have invented a certain new and useful Improvement in Cab Turrets, of which improvement the followinglis a specification.

y invention relates to manifolds serving for the connection of steam supply pipes for auxiliaries, to a steam boiler, and is more particularly designed for application in the cab turretsof locomotive engines. The object of the invention is to eflect a structural simplification and economization of appliances of the character-stated.

The improvementclaimed is hereinafter fully set forth.

In the accompanying drawing: Figure'l is a view, in perspective, ofa cab turret, embodying my invention; and, Fig. 2, a view, partly in end elevation, and partly in vertical tra'nverse section, and ,on an enlarged scale, of the same,'the lower sectioned portion being on a central. plane, and the upper, in a plane at one vside of the central plane.

In ordinary present practice, a steam turret or casing is connected to a locomotive boiler, in a location convenient for access by'the engineman, for the purpose of receiving steam for the supply of auxiliary devices of the boiler and engine, such as a blower, injectors, air brake pumps, etc. The supply of steam to the turret is controlled by a manually operated stop valve, by which the supply may be regulated in quantity or entirely cut ed, as required. A plurality of delivery pipes, each serving one of the several auxiliary devices, isconnected to the turret, said pipes being independently controlled-by a corresponding number of globe or angle valves, of the construction ordinarily manufactured for the trade, the casing of each of said valves being interposed between, and connected to, its delivery pipe and the turret.

In the practice of my invention, referring descriptlvely to the specific embodiment thereof which is herein exemplified, the exterior valve casings and intermediate con-. 1

nections of prior and present practice, are dispensed with, and the control valve casings of the auxiliary delivery'pipes are located in the inside of the turret.

The turret, 1, is a chest creasing, of sub- I stantially rectangular section, having a downwardly projecting extension or steam supply nozzle, 1, at the middle of its lower side, on which there is formed a flange, 1 through which it is adapted to be secured to a steam boiler sheet. The admission of steam to the turret is controlled by a stop valve, 2, of the lift or poppet type, seating on a valve face, 1, in the turret, and secured on a stem, 2, passing through a stuifing box, 2, and manually operable by a handle or hand wheel, 2.

Steam from the turret is supplied to any desired one or more of a plurality of de: livery pipes, 3, leading to auxiliary devices, each of said pipes being connected to one of a corresponding number of sleeves, 3 screwed into one of the walls of the turret,

'and projecting thereinto, and having a valve face, 3", machined on its inner end. The admission of steam to the several delivery pipes, 3, is independently controlled by regulating valves, 3, each seating on one of the valve faces, 3, and connected by a nut, 3, to a stem, 3". The stems, 3, have a threaded engagement with stufling boxes, 3', through which they pass to the exterior of the turret, and which are made steam tight by packing nuts, 3 Each of the valves, 3, is manually seated or unseated, as desired, by rotation of its stem, 3, in the proper direction, through a hand whet-1,3, on its outer end.

The practical advantages of my invention, in the particulars of simplification of construction and economization of structural cost and space occupied, are substantial, and will be readily recognized by those skilled in the art of locomotive construction.

I claim as my invention and desire to secure by Letters Patent:

1. In a locomotivecab turret, the combination of a chest or casing, adapted for connection to a boiler sheet; a plurality of integral valve seats and auxiliary delivery pipe connections, each fitted in a wall orsaid chest and projecting thereinto; a plu rality of valves, each fitted to seat on one of said valve faces; and means for manually actuating said valves.

2. In a locomotive cab turret; the combination of a chest or casing, adapted for connection to a boiler sheet; arplurality of sleeves, fixed in a wall thereof and projecting thereinto, each of said sleeves having a valve faceon its inner end and adapted for connection to an auxiliary delivery pipe on its outer end; a plurality of valves, each fitted to seat on one of said valve faces; and means for' manually actuating said valves. v

3. In a locomotive cab turret, the combination of a chest or casing, adapted .for connection to a boiler sheet; a pluralit of sleeves, fixed in a wall thereof and pro ecting thereinto, each of said sleeves having a "alve face on its inner end and adapted for connection to an auxiliary delivery pipe on its outer end; a plurality of valves, each fitted to seat on one of said valve faces; threaded stems, on-which said valves are secured; stuffing boxes fixed in the casing and internally threaded to engage the stems; and hand wheels, for rotating the stems.

4. In a locomotive cab turret, the com bination of a chest or casing,'having a nozzle adapted for connection to a boiler sheet and a valve seat in said nozzle; a manually operable valve, controlling said nozzle; a plurality of sleeves, fixed in a wall of the casing and projecting thereinto, each of said sleeves having a valve face on its inner end and adapted for connection to 'an auxiliary delivery pipe on its outer end; a plurality of valves, each fitted to seat on one of said valve faces; threaded stems, on which said Valves are secured; stuffing boxes, fixed in the casing and internally threaded to engage the stems; and hand wheels, for rotatin the stems.
