ifiPiCIE'IC-ATION forming part of Letters Patent No. 308,333, dated November 18, 1884.
Application filed July 17, 1884. (No model.)
To all whom it may concern.-
Be it known that we, Jornv W. Twrees and JOHN H. PORTER, citizens of the United States, residing at Jackson, in the county of Jackson and State of Michigan, have invented certain new and useful Improvements in Cylinder-Cocks; and we do declare the following to be a full, clear, and exact description of the invention,such aswill enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.
This invention relates to cylinder-cock discharges for locomotives; and it consists in the novel construction and arrangement of parts hereinafter fully described, and pointed out in the claims.
In the drawings, Figure 1 is a front elevation of the forward part of a locomotivetruck provided with our improvements. Fig. 2 is a top plan view of same. Fig. 3 is a side view enlarged of one of the cylinders with the plug-operating devices. Fig. at is a detached vertical section of one of the cylinders,
valve-chambers, and the plugs. Fig. 5 is a detail view of one of the plugs, all of which will be described.
The cylinders A A maybe of ordinary construction, and connected in suitable manner with the boiler, in order that the steam may be properly admitted in the operation of the machine. The cylinder-cocks Bare arranged near the oppositeends of the cylinders, and are formed with pipes B, opening at their lower ends,into valve-chambers B ,having discharge-ports O and drip-ports O. Pipes 0 G are extended rearwardly from the chamber B and discharge into the receiving-tank D. 'We prefer to unite the two pipes from the chambers of the same cylinder in a V- coupling, D D, so they will discharge into thereceptacle D through a common pipe, as will be understood from Fig. 2. Receptacle D is provided with adischargepipe, D which may be carried into the smoke-stack or elsewhere, out of sight. Plugs E arejournaled in chambers B These plugs are provided at one end with an arm, E, and are formed with a semi-annular groove, E formed substantially as shown in Figs. 4 and 5, so it may register with and establish communication between pipe 13 and discharge-port O, or ports C and G, as will more fully appear hereinafter. The plugs may be rotated in the cylinders, and to accomplish this we preferably connect the arms E of the plugs of each cylinder by a rod, E, as shown in Figs. 3 and 4, so that the operation of one will work a corresponding operation of the other; Levers F F are pivoted midway their ends in rear of the cylinders, and have one arm connected by rod F with the rear plug-arm, and their other arm connected with a rod, F extended into the cab or elsewhere, where it may be conveniently operated by the engine-driver. It will be noticed that these levers are pivoted on a shaft, G, extended transversely across the framing; and it will be understood that if this shaft be jonrnaled so it may be rotated and the levers be secured to it, it will be only necessary to rotate this shaft by the lever F, or otherwise, in order to adjust the plugs of both cylinders.
In operation, when the parts are in the position shown in Fig. 4, the discharge is through pipes B G into the receiver D, the drip-port being closed. When the engine is stopped, the plugs may be adjusted to the position indicated in dotted lines, same figure. the water collected in pipes C may be drained out, so as to prevent its freezing or clogging, and this, it will be understood, is simply a dripping, not a forcible discharge, as when it is ejected bythe force of steam, as the cylinder-cocks are, in this position of the plug, shut off and the discharge is stopped. This arrangement of the plugs, it will be noticed, may also be used when it is desired to shutoff the discharge from the cocks.-
Having thus described our invention, what we claim, and desire to secure by Letters Patent, is
1. In a cylinder discharge-cock, the valvechamber B provided with port B, communicating with the cylinder and provided with discharge-port O and drip-port O, and having I the plugvalve E secured in it and provided with the semi-annular groove E adapted to register with ports B O or C G, the said plug being rotatable, whereby it may be adjusted to form communication between either of said pairs of ports, substantially as and for the purpose specified. I
2. A cylinder discharge-cock having chain- 5 her B connected with the cylinder and provided with steam-discharge and drip ports,
the pipe 0 receiver D, the plug secured and operating mechanism, substantially as set forth..
In testimony whereof we affix our signatures in presence of two witnesses.

rotatable in the chamberBZand provided with E \Vitnesses: pendent arm or stem, the rod connected to LEWIS M. POWELL,
10 the arm or stem of the plug, and the necessary GEORGE POWELL.
