EUGENE N. YEAMAns, 0F HOUSTON, TEXAS, ASSIG-NOR, BY manor AND MESNE ASSIGNMENTS, TO THE YEAMANS COMPANY, A CORPORATION OF TEXAS.
AUTOMATIC FOUNTAIN-VALVE non LOCOMOTIVES.
To all whom it may concern:
Be it known that I, EUGENE N. YEAMANS, a citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have invented certain new and useful Improvements in Automatic Foun tain-Valves for Locomotives, of which the following is a specification.
This invention relates to new and useful improvements in' an automatic fountain valve for locomotives.
The object of the invention is to provide a valve of the character described which will be automatically closed in case of overturning of the locomotive so as to effectually cut off all escaping steam from broken pipes to prevent the scalding of the enginemen who may be" trapped in the cab.
Another feature of the invention resides in the provision of means wherebv the valve may also be closed by the engineer at any time he may desire to cut the steam off from the fountain and from the various pipes leading therefrom.
With the above and other objects in view the invention has particular relation to certain novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings, wherein:
Figure l is a sectional side elevation of the fountain showing the valve applied thereto.
Fig. 2 is a perspective view thereof, and
Fig. 3 is a side view of the valve controlling mechanism.
Referring now more particularly to the drawings, wherein like numerals of reference designate similar parts in each of the figures, the numeral 1 refers to the locomotive boiler having the fountain secured thereto and formed of the neck 2 and the T 8, the latter comprising injector pipes which lead in opposite directions from the neck. Practically all of the steam utilized for the various purposes of the locomotive, excepting the steam .for driving the same, is discharged through the fountain. The inner end of the neck 2 is formed into a valve seat 4. Secured in the fountain, opposite the valve seat 4 is a stuifing box 5 through which the valve stem 6 extends. Fixed to the inner end of this stem is the valve 7 adapted to rest on the seat 4 and when so seated, to close the fountain neck 2. The outer end Specification of Letters Patent. Application filed March 3, 1917, Serial N 'o." 152,226 Renewed January Patented May 6, 1919. 24, 1919. Serial 110,272,969.
of the stem is enlarged forming a head 8.
uurrounding the stem is a coil spring 9 which rests on the stufling box and bears against the head 8 and tends to hold the valve seated. A lever 10 is pivoted to the fulcrum 11, one end of the lever being pivoted to the upper end of the valve stem and the other end being free. A standard 12 is fixed to the boiler and to the upper end thereof, a trigger 13 is pivoted. Alateral arm 14 is inte ral with this standard and the free end thereof has the cage 15 carried thereby, provided to retain the spherical weight 16. The weight normally rests on one end of the trigger while the other end thereof engages under the free end of the lever 10. and holds said free end elevated compressing the sprin 9 and holding the valve 7 open. If the locomotive overturns, as in case of an accident, the weight will be displaced, freeing the trigger and the valve will be closed through the influence ofthe spring 9 and all steam cut oil from the fountain, and from broken steam pipes, preventescaping steam from burning those trapped in the cab. I
A cable 17 is attached to the weight and by means of it the weight may be manually displaced and the valve closed at any time desired, in case it is desired to repair the injector or steam pipes. i
What I claim is: V
1. In a device of the character described, the combination with a boiler of a T fountain connected thereto and leading therefrom, a valve seat formed in the neck of said fountain, a valve co-acting with said seat, a bearing opposite said seat, a valve stem to which the valve is fixed slidable through said bearing, a yieldable member in operative connection with the stem tending to hold said valve seated, a lever, one end of which is pivoted to the outer end of the valve stem and the other end of which is free, a trigger normally holding the free end of said lever elevated to maintain the valve in open position and a displaceable weight normally holding the trigger in operative connection with said lever.
2. In a device of the character described, the combination with a boiler of a T fountain secured thereto whose neck is formed into a seat, a valve adapted to close said seat, a yieldable member connected to the valve stem and tending to hold the valve seated,
a trigger, a lever pivoted at one end to said 7 stem and Whose other end is normally engaged by thetrigger to hold the valve open a cage-through which the trigger extends and a clisplaceable eight resting in said cage on said trigger normally holding said trigger in engagement With said. lever.
In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
