TRAIN-PIPE COCK AND OPERATING MECHANISM THEREFOR,

Specification of Letters Patent.

Patented N (W. 25, 1913.

Application filed October 28, 1811. Serial 1i 0. 657,253.

To all whom it may concern:

Be it known that we, EMORY B. DUNKEL and FRANK S. BOWMAN, citizens of the United States, residing at Lucknow and Harrisburg, respectively, in the county of Dauphin and State of Pennsylvania, have invented new and useful Improvements in- Train-Pipe Cocks-and Operating Mechanism F Therefor, of which the 'following'is a specification.

The invention relatesto a train pi cock used now as angle cocks forair bra e systems, .and more particularly to the class of angle cocks, and operating mechanism there- I for.

The -primary object ofthe. invention is the .provislonof a cock of this character in which the handle thereof is disposed beneath the same and may be readily and quickly operated for the opening or closing-of the cock, without ,requiring an operatorgoing between the cars for this ur'pose, thereby avoiding the possibility of injury or the loss of life, resultant therefrom.

Another object of the invention is the provision of a train pipe cock in which the handlelthereof will be sustained or locked in its open or closed position, so as to revent ting of the handle by reason of shocks and jars incident to the travel of a train, the cock beeither opened in readily and easily-set in g sides of, the

or closed position from both car, thereby operator going between the cars when manipulating the cock. I

' A further object of the invention is the provision of a device of this character which is simple in construction, thoroughly reliable and eflicient in o eration, and inexpensive in manufacture and installation.

With these and other objects in view, the invention consists in the construction, combination and arrangement of parts, as will be hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the claim hereunto appended.

In the drawings :-Figure 1! is a fragmentary end elevation of a cap, showing the train pipe cock mounted fliercon and the opcratin mechanism therefor constructed in accor ance with the invention. Fig. 2 is a fragmentary bottom plan view of a car body, showing the train pipe cock and operating mechanism in position thereon. Fig. 3 is a avoiding the necessity of the diametrically opposite points,

'car

fragmentary side elevation. Fig. 4 is an enlarged side elevation of the train pipe cock. Fig. 5 is a bottom plan view thereof,

showing the handle inshifted position by dottedlines. Fig. 6 is a detailvertical longitudinal sectional view through the handle, showing the locking pin in side elevation. ig. 7 is a verticaltransverse sectional view through a portion of the body of the cock andthe handle. Fig. 8 is a perspective view of one of the hangers for the operating mechanism. Fig. 9 1s a-perspective view of one; of the levers-of the operatin mechanism. 'Fig.- 10 is a side elevation o a sli ht modification of av mechanism.

Similar reference characters indicate correspondin parts throughout the several views of t e.drawings.'

Referring to the drawings by numerals, 5 designates generally a portion of the body of a freight car, having mounted on its end sill 6 a coupler head 7, and a bracket 8 for the brake rod 9, as. usual. Also suitably mounted beneath'the sills of the car,-in suitable brackets, is the train pipe 10 provided at each end with a cock, presently described.

The train pipe cock comprises-a straight body 11 having rotatably fitted therein the valve, with stem 12, the same being held against displacement therein by means of a cap 13, and connected to this valve stem :is' the handle 14, the same being formed with a vertical socket 15 in its thickened portion 16, the socket 15 being closed at its open end by meansof a removable screw plu 17 and working within the socket is a 100 ing in 18, the same also working through a suita 1e guide opening 19 opening through the inner face of the handle and communlcating with the said socket 15, the pin being designed to engage in beveled indentations or notches 20 formed in the flattened face 21 of the body, so that the handle 14 thrown position for either opening or closing the train pipe cock.

Formed on and projecting outwardly from the flattened face of the body 11, at are stop difgs 22, against which is adapted to contact the handle 14, when being thrown to either open or closed position. 1

Suitably fastened to the end'sill 6 of the body 5, on opposite sides of the point of disposition of the angle cock, are hangers,

hanger for the operatmgwill be locked in its each comprising a rod "23, the same being bent at one end to form reversely disposed open loops 24, with which are engaged the vent swaying of'the hanger while the oppo site end of the rod is formed with a guide eye 25, and through these eyes of the said hangers are passed rods 26,.thcinner ends of which are'su tahly connected to the free end of the handle i l, while their outer ends proyect a convenient distance spaced from thepla'mes' of the sides of the car, and terminate 1n handles 27 to be grasped by an operator,: so thatj uponpulling or pushing ,upon one of the rods'26 the handle 1 of the angle cock-may be shifted for the operating of thetrain pipe cook; The push rod 26 is to bepushed or pulleduntil the handle 14 comes in contact with the stop lug 22, thus when the handle 1i is pushed or-pulled to meet the inside lu 22,. the valve is opened andwhen the handle 14 is pushed or pulled to meet the lug 22 on the outside of the body of the cock, the valve'is closed.

By reason of the fact that the handle of the train pipe cock is operated beneath the train,- numer'ous accidents and troubles which arise from protruding bolts coming-in contact with the handle and closing the same, thus shut-ting off air in the remainder of the train, will be avoided, the handle being entirely out-of danger v I IngFig'. 10, there is shown aslight ,modification of hanger for supporting the rods 26, wherein'there is shown a rod 28 having a threaded end 29 provided with jam nuts 30 which permit the mounting of the saidrod 28 upon the sill of a steel freight car,

the opposite end of the rod-being formed with a guide eye 31, through which is passed the rods 26.

From the foregoing, taken in connection with the accompanying drawings, it is thought that the construction and operation of the invention will be readily understood, without requiring a more extended explanation.

What is claimed is: I

A train pipe cock including a body and a turning plug mounted therein, said turning plug having a stem at its lower end extending below the under side of the body and a handle attached to said stem, said body having stop lugs, on its lower side, on opposite sides ofthe stem and in the'path of-the handle and also having spaced beveled notches in its lower surface, between said stop lugs,

the bevels of said notches extending in opposite directions and said notches being deepened at their outer sides, and a spring pressed pin mounted-in the handle and having a terminal rounded end to cooperate with saidnotches and lock the handle in engagement :with the stop lug and permit movement of the handle in the opposite directions undersuflicient pull in combination with means connected toth handle and projecting in both directions and beyond, f I

to permit operation of-the handle from opposite points relatively remote therefrom.
