FOUR-WAY COCK.
SPEGIFIGATION forming part of Letters Patent No. 717,899, dated January 6, 1903.
Application filed July 10, 1902.
To all whom it may concern.-
Be it known that I, PATRICK MCDONALD, a citizen of the United States of America, residing at Larimer, in the county of Westmoreland and State of Pennsylvania, have invented certain new and useful Improvements in Four-Way Cocks; and I do hereby declare the following to be a full, clear, and exact de scription thereof, reference being had to the accompanying drawings, which form a part of this specification. a
This invention relates to certain new and useful improvements in four way cocks adapted for use in connection with 'an airbrake train-line.
In the accompanying drawings I have illustrated my improved four-way cock, in which drawings- Figure 1 is a plan view of my four-way cock. Fig. 2 is a side view. Fig. 3 is a sectional view on line X X of Fig. 1. Fig. 4 is a sectional view on line 5 5 of Fig. 2. Fig. 5 is a View showing the application of the invention to a train-line, and Fig. 6 represents diagrams showing the various service positions. I
In the drawings the numeral 1 designates the shell or casing having a tapered opening 2 therethrough and air-passages or parts 3 and 4 communicating with the said opening and train-line connections or ends 5 and a similar part 6 communicating with said opening and triple-valve end '7. A tapered plug-valve 8 is fitted into the tapered opening of the easing and is held in position by a spring 9 and cap 10. The plug-valve is provided with a side or cut-away part 11, straight-away part 12, and part 13 branching from said straightaway part, which parts are adaptedto register with the parts in the casing and with the dead-air parts 14. At the upper end of the casing is found four stop-notches l5, and to the top of the plug is attached a hand1e l6,
which is provided with a spring-catch 17 to engage said stop-notches. Said spring and notches serve to indicate the position and retain the cock in such position.
In practice the train-line is connected to the ends 5 and the pipe leading to the triple Serial No. 115,008. (No model.)
valve to the end 7. If it is desired to let air from the train-line on the left to the triple valve, the cock is turned into position shown at Figs. 1, 2, 3, or 4 and at B of Fig. 6. To let airfrom the train-line into triple valve at right, the cock is turned one quarter, as at C, Fig. 6. From both cars to triple the cock is as at D, Fig. 6, and for straight-away train-line as at A, Fig. 6, the stop-spring 17 and notches 15 holding the cock at any position to which the same may be turned.
This device does away with several independent cocks on the train-line, and the dead air remaining in the parts escapes out of parts 14.
By the expansion dead air it will be understood is meant the air which remains in the pipes under pressure and which it is desired to release when the air is not required for service, and which air is released to remove the pressure from the parts of the cock and connected mechanism.
Having fully shown and described my invention, whatI claim as new, and desire to secure by Letters Patent, is-
1. In combination with a train-line, the four-way cock or valve, having exhaust-openings, a plug in said valve having openings adapted to register with the openings of the valve and with the exhaust, and means for holding the plug in proper position.
2. The combination with a train line and connection to the triple valve, of a four-way cock adapted to operate as set forth, means to relieve'the parts of dead air and means to indicate and retain said cock in any of its operative positions, as shown and set forth.
3. In a four-way cook the shell 1, having the tapered opening 2; air- passages 3, 4 and 6; dead-air passages 14; cap 10, having a seat for a spring, substantially as described and shown.
In testimony whereof I have hereunto affixed my signature in the presence of two subscribing witnesses.
PATRICK MCDONALD.
