GOVERNOR-VALVE.

To. all whom it may concern.' Y

Be it known that I, VILLAM F. Caivrnaon, a native-born citizen of the United States, residing at Ogden, in the county of Weber and State of Utah, have invented new and useful Improvements in Governor-Valves, of which the following is a specification.

The invention relates to an improvement in governors and particularly in a double acting governor in that it will automatically cut od the steam from the engine when at rest or under speed limit to which it has been set, whereby in the event of accident to the governor or the mechanism operating the same, the engine will be prevented from racing. j

The main object of the present invention is the provision of a governor carrying a double valve structure for each steam opening controlled by the governor, the valve being arranged so that the governor may control the passage of the 'steam through the opening when the governor is at rest or at the maximum movement for which it has been set.

rIhe invention in the preferred form of details will be described in the following speciication, reference being had particularly to the accompanying drawings, in which Figure 1 isa sectional view illustrating the improved governor. Fig. 2 is an enlarged sectional view of the steam and tubing therefor, whereby the valves are removably secured to the stem in the convenient manner. Fig.`3 is an enlarged plan illustrating particularly one of the communicating openings between the chambers of the governor shell.

In carrying out the present improvement, it will be understood that the governor above the shell or steam casing 1 thereof is of any usual or preferred construction, and that in this particular I contemplate they use of any desired or appropriate type of operating mechanism. As usual, the shell 1 is divided into an outer chamber 2 into which the steam is admitted at 5 andan inner chamber 4: from which the steam is delivered to the engine through an opening 3. The chambers 2 and et communicate through upper' and lower openings 6 and 7, and in the usual type of governor` these openings are controlled by valves adapted when the governor has reached a predetermined speed to cut off the means of communication and so throttlel down the engine,

. The stem 81o f the governor `is of theusual construction and for the purposes of my invention I secure thereon sleeve sections 9 and 10 disposed in superimposed relation upon the stem and secured through the medium of threads, as illustrated. Each sleeve section has a circumferentially enlarged cylinder portion 11, the enlargements coperating respectively with the openings 6 and 7. Each opening is provided with aremovable valve seat 12 having a central guide member 13 supported through the medium of spokes 141 from the valve seat ring 12, the guide 13 slidably receiving enlarged portions 11 of the sleeve sections, whereby to guide the stem in its reciprocatory movement. Each sleeve section above and below the enlargement is threaded at 15 to receive a valve, the valves being designated as 16, 17, 18 and 19, the valves 16 and 17 being thus arranged respectively above and below the openings 6, while the valves 18 and 19 are similarly arranged with respect to the lower opening 7. Each valve is preferably provided with a clamping extension 20 of slotted formation, with which a clamping nut 21 cooperates, whereby the valve may, after beingproperly seated upon the stem section, be secured in place against the possibility of movement.

As thus described, it will be obvious that the valves 16 and 17 are arranged for opposite coperation with the opening 6, a similar result brought about by the valves 18 and 19 with respect to the opening 7, that is to say that the valves 16 and 18 will close the openings 6 and 7 when the valve stem is at its highest limit of movement, while the valves 17 and 19 will close the openings 6 and 7 when the valve stem is at its lowest limit of movement.

The chambers 2 and t are further communicating through a port 22 located at one side of the opening 7 and controlled through an appropriate valve 23 operable through any shell.

Under the maximum predetermined speed of the governor, the valves 16 and 18 will Vclose the respective openings 6 and 7 to throttle the engine, while in the event the governor becomes inoperative from any cause, the valves 17 and 19 will similarly close the opening. Therefore the governor is of double acting type and will automatically cut olf steam from the engine in either estreme positions of the governors. In

a engineer control of the dead engine indestarting the engine, after cessation of the secured to said stem, and spaced oppositely 10 governor operation, the valve 23 is operated acting valves carried by each sleeve section. to admit steam to the engine independent of In testimony whereof I aiiix my signature the openings 6 and 7, thereby giving the in presence of tWo Witnesses. pendent of the governor.
