WALTER J. RICHARDS AND CHARLES P.
ToLMAN, oF1\uLwAUKEE, wisconsin. 'I
WATER-GOVERNOR.
To allwhom 'it may concern:
vlie it known that we, WALTER J. RICHARDS and CHARLES P. ToLMAN, citizens oi the United States, re-v siding -at Milwaukee, inthe county oi Milwaukee and State oi Wisconsin, have invented a certain new and its dbject is to provide a magnetic valve which ,will be automatically operated to open fthe supply circuit through the water jacket when the compressor or other machine is in operation and to automatically close the water circuit when the compressor or the machine is Our invention is particularly adaptable for ilse iii connection with electric motor driven air compressors that are tohe run intermittently and the controlling coil o the valve' may be so connected with the circuit operating the driving motor that the controlling valve is opened when the motor is started and closed when the motor ceases running, the controlling valve being interposed in the path of the water ilowing from thev supply source to the water jacket about` the compression cylinder.
The valve mechanism consists oi a solenoid winding disposed about the core, and in which the core is adapted to be drawn upon energiaation oi the coil, -Which coil may be included serially in the motor circuit, or otherwiseconnected therewith to insure energization-thereoi when the motor starts and denergization thereof when current flow is withdrawn from the motor. The stem oi the controlling valve engages with the 4end of the core and upon energization ofthe winding is moved b'y the attracted core to open passage through the valve `chamber and to allow the passage i water tothe Water jacket, a spring serving to close the'valve upon denergization of the solenoid winding.
Our inventionvis best understood by 'reference to the accompanying drawings, in which:
Figure 1 shows a side elevation of the valve and con'- trolling mechanism, Fig. 2 shows a longitudinal sectional view thereof taken on line 2*-2 of Fig. 1, Fig. 3`v is a top viewthereoi, and Fig. 44 shows a utilization ofA the magnetically operated valve` for controlling 'the water jacket supply-for the compression chamber of an air compressor. 3 Like reference characters refer to like partsthroughoutthe figures. dA supporting base 1 is adapted to be screwed or bolted to any support and a cylindrical cup-shaped casing 2 is secured to-the upper part of the/base. Within the 'Specification of Letters Patent.

are thus securely held in place` and well insulated.
' In Fig; 4 we'have shown an air compressor driven by an electric motor, the circuit for which is controlled by a switch armV actuated and adjusted by the pressure in 35 main b.
36 leading to the reservoir 37 and with inlet valves 38,
inder and connects by piping 4() with the top of a cool A water jacket 39 surrounds the compressor cyling fluid reservoirAl and -also connects by piping 42 with the bottom of the reservoir, and a magnetically controlled valve mechanism, such as described in Figs. 1, 2 and 3, controls the circuit through the piping 42.
The tube 43 of a well known Bourdon gage is connected -with the reservoir 37 and at its end engages through nk mechanism 44 with 'a switch arm 45hadapted to enl 'gage terminals 46 and 47. A solodoid coil 48 connects with the contact 46 and with a shoe 49 connected through a switch 50 with the main conductor a of the supply circuit c while a solenoid windingl connects with the Contact 47 and with the main conductor b. A
As the pressure in the reservoir 37 becomes too low, the switch arm 45 will move over and engage the contact-46,
` whereupon a circuit is closed from the supply conductor rent will flow from the main conductor a through the shoes 49 and 54 directly through the motor and through the magnetic valve. Upon current Vflow through the motor and through the solenoid winding 8 the motor will start and at the same time the core 9 of the mag'- netic valve will be drawn inwardly yto remove the valve 19 from its seat'to allow the water from the supply tank 41 to flow through the piping 42 and into the water` jacket, the valve being held open as long as current A flows through the solenoid winding 8, that is as long as themotor is running. As the pressure in the reservoirV 37 increases, due `to the operation of the motor, the switch arm 45 will gradually move toward and will engage the contact 47, whereupon a current will flow from the, main' conductor a through the switch 50, shoes 49 and 54through conductor 57, `through switch arm-45, conductor` 59 and through solenoid winding5l to supply main b. Upon energization thereby o1' the winding 51 the core 52 will be attracted and the shoe will be removed from the shoe 49, thus disrupting the circuit through thernotor and through the -solenoid winding 8. The motor therefore stops and the valve 19 is closed, due to the spring 28. ,y
We .thus provide electrically controlled valve means which allow water supply to the water jacket only upon operation of the compressor piston, We do not wvish to be limi'ited, however, to tho adaptation of the'niagnetically i'controlled valvey as hereinishown., as a valve ol' this kind may be employed whereveran electric eir-V cuit isutilized in'connection with the machine or engine. l g
Weclaim as new'and desire to secure by Letters Patentz- The combination of a compression cylinder surrounded by water jacket,.an electricA motor for reciprocating,r a piston within said cylinder, an electric circuit for said motor, ay supply pipe leading to saidavater jacket, a valve chamber interposed in the path ofnsztid supply pipe. a.
'valve in said chamber for normally closing passage through said supply pipe, a stem. extending froinsaid valve, a bushing through which said valic stein extends. a collar on said valve siem, a spring` interposed between said collar and valve seat' to normally hold said valve in a closed position, a solenoid core, a solenoid winding for said core connected iu the motor circuit in series with the motor, a piece of non-magnetic material secured io said core and engaging said valve stem. energizalion ol said solenoid causing attraction of said core towards said valve stem to cause4 the, valve to be opened to admit passage of water throughlsaid water jacket, said solenoid being energized and deinergized upon closure and'openin.;r of the motor circuit.
