To all whom it may concern:

Be it known that I, QARLG. GUSTAFSONi, citizen of the. United States,- residing at Sioux City, in the county of WVoodbury and State of Iowa, have invented certain new and useful Improvements in Angle-Cocks, of which the following is a specification.

This invention relates to angle cocks for train-pipes, andhas for its object the provision of an angle cock which may be operated from either side of the car and which will be so constructed as to avoid the liability of freezing; r The invention will be hereinafter fully described and its novel features subsequently pointed out in the claim following the description. I I

In the accompanying drawings which fully illustrate the invention; Figure 1 is a rear elevation of the angle cock, the operating handle being removed; Fig.2 is a front elevation of the same, the plug and cap for closing the plugchamber being removed; Fig. 3 is a side elevation of the angle cock; Fig. 4 is a vertical transverse section; Fig. 5 is a vertical longitudinal section of the angle cock showing all the parts assembled; Fig. 76 is a rear elevation with the handle in position ;1Fig,. 7 is a detail view of the latch mounted inthe han dle; Fig. 8 is a detail end view of the handle.

My improved angle cock, 3', is secured directly on the end of the train pipe by a threaded connection, as indicated at 4, and a hose 5 is connected to the end of the angle cock opposite the train-pipe to extend to the train-pipe coupling, as will be readily un'- derstood.

The angle cockconsists of a bodyhaving anupper arm 6 which is threaded onto the end of the train-pipe, the main body of the cock depending from the said upper arm 6 and therlower entremity of the body being turnedat a slight angle to form the annulus 7 to which the hosecoupling 8 is? fitted. The

angle cock is bored throughout its length to provide a passage for the fluid and in the wedge it firmly in place. The plug, it, has" a conical body adapted to seat Within the said bushing and turn therein and has one end extended, as indicated at 12, to project through the side of tliebody of the cock and have a handle secured thereto. A central diametrical passage or port 13fis formed through the plug so that, if the plug be turned to a position in which theport will register with the openings 10 in the bushing, the flow through the cock will be uninterrupted and the air or steam may pass therethrough tothe coupling, while, if the plug .be turned to l a position in which the port l3, will extend across the plane of the openings 1 0 a t a rightiangle thereto, the flow will be cut off and the train-pipes may be vuiicoupled withoutany appreciable loss of s teain'sor a'irl On the side of the body, immediately adjacent the larger end of l the bushing se'at, is,, for11ie'd an external collar l-it' which is internally threaded, to be en-' Patented his,

l Th .p ee insend 1 the l ke i .a -i

e ilai a shbimmostx leafly i Fi -[61. nd is a sbs onsfi ue edsi th irib 2 s thaten angular engagement between the plug and the handle 23 Will be ,efi'ected when the upper end of the handle, which is provided with a similarly shaped transverse opening, is engaged over the end of the plug. The upper end of the handle and the projecting end of the plug are provided with openings adapted to register, and a pin 24 is inserted through the said openings so as to lock the handle to the plug whereby movement of the handle, independently of the plug in any direction, will be prevented. The upper end of the handle plays against a quadrant 25 formed on the adjacent side of the angle cock body, and this quadrant is provided at its opposite sides with the lugs 26 which constitute stops to limit the movement of the handleand is also provided with the diverging grooves 27 disposed at a right angle to each other and adapted to be engaged by a latch 28 carried by the handle so that the handle will be held in either of its set positions. When the latch engages one recess or groove, the air will be cut out and when the latch engages the other groove or recess, the air will be cut in, as will be readily understood.

The latch 28 is seated within a tubular portion 29 of the handle, which tubular portion extends outwardly from the upper end of the handle at a right angle thereto and has the main body or lever of the handle depending from its outer end. The outer end of the tubular portion or barrel 29 is internally threaded to receive a cap 30 which has an outer angular end adapted to be engaged by a wrench or similar tool when inserting or removing the cap and is also constructed with a rib or flange 31 which limits the inward movement of the cap by engaging the outer surface of the handle, as will be readily understood on reference to Fig. 5. The latch 28 is mounted in the barrel 29 in advance of the cap 30 and comprises a stem 32, an annular disk or body 33 at one end of said stem, and a locking tongue 34c projecting from the said disk or body toward the open end of the barrel. The end of the locking tongue 34: is tapered, as clearly shown in Fig. 7, to properly engage the inwardly converging walls of the grooves 27 and thereby avoid sticking in the grooves, while, at the same time, the handle will be efi'ectually held in either of its adjusted positions. The tongue 3a is fiat, as clearly shown, and plays between the lugs or projections 35 formed within the barrel at the end thereof so that rotary movement of the latch cannot occur and it Will be constantly maintained in proper position to enter either groove 27. The annular body or disk 33 constitutes a stop to prevent ejection of the latch by engaging the inner sides of the lugs 35, and a spring 36 is coiled around the stem 32 between the said body or disk 33 and the cap 30, as clearly shown in Fig. 5, said spring tending by its expansion to project the latch so that it will automatically engage either groove. When sufficient force is applied to the lever portion of the handle to turn the same and the plug, the tapered end of the latch, co-acting with the converging faces or walls of the grooves, will permit the latch to automatically recede from the groove and compress the spring 36, but unless suflicient force is applied to the handle to turn the same laterally, the latch will hold the handle in its set position and consequently accidental turning of the plug will be prevented.

The depending lever portion of the handle is provided at its lower end with two openings 37 which receive pivot pins whereby the inner ends of operating rods are attached to the handle. These rods extend laterally to opposite sides of the car and pass through suitable hangers. By actuating the operating rods, the valve may be easily shifted and the latch will hold it in its shifted positions.

The operation and advantages of my improved angle cock are believed to be evident from the foregoing description, taken in connection with the accompanying drawings, and detail mention of the same is deemed unnecessary.

By the use of my improvements, the necessity of the trainmen passing between the cars in order to operate the angle cocks is overcome so that life and limb will not be endangered and the cock may be easily operated from either side of the car and will not be apt to freeze and stick in extreme weather.

What I claim is An angle cock for train-pipes comprising a tubular body having a vertically disposed portion, a tapered turning plug seated horizontally in said vertically disposed portion, means on the smaller end of said plug for turning the same, a socketed cap secured in the side of the body over the larger end of the plug, an opening through said end of the plug establishing communication between the socketed portion of the cap and the bore ofaplug, anda drain passage in the wall of the body establishing communication between the socket of the cap and the bore of the body below the plug.

In testimony whereof I aifix my signature in presence of two witnesses.
