supplying water to the water jacket. a citizen of the United Referring first to the general arrange- Pittsburgh, :in the county of Allegheny and ment of parts indicated in Fig. 1, 1 is the State of Pennsylvania, have invented cerwater jacket around the cylinder of the gas tain new and useful Improvcmcntsin Valves engine illustrated; 2 is the water supply for \Vater-Jacketcd Explosion-Engines, of pipe for the jacket, connected to a water which the -t'ollowing is a specification. main; 3 is the drain pipe for the water The invention relates to explosion engines, jacket, such drain pipe leading into the and particularly to valve mechanism for sewer a 5 is the gas or fuel supply pipe controlling the inflow and drainage of the leading to the carhuretcr (i; 7 is the water water jacket. The invention has for its outlet pipe from the jacket, leading to the primary objects; the provision of an iinsewer; and 8 is the casing of the valve mechproved sai'cty arrangement of valves for anism for controlling the supply of fluid insuring the opening of the drainage outlet through the pipes 52, 3, and from the water jacket and closing of the The construction of the valvemechanism inlet thereto when the fuel silpply inlet is in the casing 8 will he understood by referclosed, and vice versa; and the provision of once to Figs. 2, 3, and t, Mounted in the means oi the character specified of very casing are three transversely extending rocompact construction, and one in which improved means are Tu'ovided for throttlingthe fluids passing through the inlet pipes.

illustrated in the aecoi'npairying drawing, wherein- Figure 1 is a side elevation of an engine valve applied thereto, is a transverse section through the tary valves 9, l0, and 11 (Fig. 3). These valves are tapered in the customary way in order to make a tight tit, and are provided with the transverse openings 12, 13, and 14 adapted to register with the openings 15, 7 10, and 17 extending through the valve easire, it being understood that theportions of the pipes Q, 3, and 5 lying on oppositc sides of the valve casing, S are screw valve mechanism, on the line II--II of Fig. threaded into the sockets on opposite sides 3, Fig. 3 is a plan view of the alve, with of the casing as indicated in Fig. 52, so that one of the three similar parts thcrcol" in the passages 15, Hi, and 17 constitute in section to show the interior construction, cil'cct portions oi the pipes 5, 3, and 2, re and Fig. 41- is a side elevation of the valve. spcctively.

It :lrequently happens in cold weather The outer ends of the valves 9, l0, and that the water jackets of gas engines are 11. are squared as indicated in [*ig. 4-, and burst through failure to drain the jacket carry the ha dles 18, 1S), and 20 connected after the engine has stopped at night, and by the bar 21. The handle 19 is extended as failure to cut oil the supply of water to the indicated at 22, to provide an operating jacket. My invention is designed to overmeans so that the three valves may he moved coinethis diiiiculty, by the provision-of an simultaneously. When the member 22 is arrangement whereby the drainage pipe in the position indicated in Figs. 1 and 4-, from the water jacket is opened and the the valves occupy the position indicated in supply pipe closed, when the gas supply is Fig. 2, at which time the drain pipe 3 is cut oft. Conversely the arrangement proclosed and the gas and water inlet pipes vides for the closure of the drainage pipe are open, this being the position when the and the opening of the supply pipe to the engine is working. It will-he seen that the jacket, when the gas or fuel supply pipe is member 22 must he moved to this position opened. The arrangement not only guards in order to admit fuel to the engine, and against the bursting of the Water jacket that this movement insures the opening of through failure to drain the jacket after theengine is stopped the water inlet pipe at night, but also to the jacket, and the closing of the drain,

so that all danger of mediately drain,

running the engine with an empty jacket is eliminated. When the handle 22 is swung 90 to the right the drainage valve 10 is opened, and the gas and water inlet pipes.

5 and 2 respectively closed, such movement occurring when the engine is shut down. The closing off of the gas therefore necessarily involves the opening of the drain pipe and the closing of the water supply pipe to the jacket, so that the jacket will imand all danger of bursting due to freezing with a full jacket is avoided.

The inner ends of the valves 9, l0, and 11 are threaded as indicated at 23, such threaded portions carrying the washers 24 and nuts 25. One side of the threaded portion 23 is cut away to provide a Hat surface 26, and the interior of the washer 24. is formed 4 so as to fit the fiat portion 26 so that-the washer turns with the valve. This eliminates the tendency of the nut to unscrew as would be the case if the washer did not turn with the valve. This is a well known mechanical expedient "for which no claim is made.

Inside each of the valves 9, 10, and 11 is a rotary throttling plug. These plugs are all similar in construction and bear the reference numerals 27, 28, and 29 (Figs. 2 and 3). as indicated in Fig. 3, the central portion of the plug 27 is-partially cut away so that the plug'only partially blocks the passage 12. It will be seen that more and more of the passage 12 may be blocked by the plug 27, by rotating it about its axis. This plug therefore serves as a convenient means for throttling the flow of fluid through the valve casing. The outer ends of the plugs 27, 28, and 29 are squared and carry the relatively short handles 30, 31 and 32 SFig. 4). The flow of fluid through each of t 1e valve parts may thus be readily throttled to suit conditions, and the necessity of other throttling devices in the pipes 2, 3, and 5 is thus eliminated. N

The inner ends of the throttling plugs 27-, 28, and 29 are provided with screw threaded portions 33 carrying washers 34 and nuts 35. The portions 33 have a flat portion at one side so that the washers 34. which fit the flat portions turn with the stems 33 and nuts 35, and any tendency to unscrew 'the nuts is eliminated. The plugs 27, 28, and 29 are tapered in order to make a tight fit with the valves through which they extend.

It will be understood that the particular embodiment of the invention illustrated and described constitutes only one of a number of forms in which "the invention may be practised. The invention is readily applicable to systems other than the one shown for providing a circulation of water through the water jacket, the system illustrated being somewhat wasteful because the water is directed back into the sewer instead of bebut such system is sufficient for the purposes of illustration.

variety of valve structures might be substituted for the one shown, the only requr we ment being that the common operating means control all three passages, so that when the drain is closed the gas and Water supply pipes will be open, alidwice versa. The use of the three independent valves is not necessary, although convenient in that it permits independent, adjustment and independent accessibility'to each valve for the purpose of repairs. lit is also obvious that where sepanate valves are used as illustrated, a large number of dificrent mechani cal equivalents might be employed for se curing simultaneous movement of the valves, depending upon the character of the valves and their degree of proximity.

What I claim is:
