The embodiment, of the invention illustrated in Fig; 1 contemplatesthe utilization of a stock tankgenerally designated 11 and aheater generally *designated 12 which are connected with each. other through the agency of a pipe line generally designated 13.. A

motor 14 is employed for operating a pump 15 for causing circulation of slush stock from that slush stocknlay] be "deposited therein from spoutssuch-as that designated 17 hav ing-Tavalve The valve 16 is motor-driven a and to this end, the motor 18 is employed,

the motor shaft having a worm 19 which meshes with a worm wheel 20 secured to the shaft 21 of the valve 16.

A brake mechanism generally designated. 22 is employed to hold the valve 16 in either anopen or closed position. This brake mech anism includes a brake drum 22 and a lever mechanism, however, this mechanism may be of any other desired construction. It may be here stated that the pipeline 13 together with the goose neck spouts such as 17 and the valve generally designated 16, cooperate to provide what might be termed a trap in which a suitable amount of slush stock which may be of a liquid or semi-liquid consistency is trapped to maintain it in a liquid or semi-liquid condition or against dehydration.

Machines of the character above referred to prior to my invention are designed to prevent dehydration'hy constant operation of the machine and constant circulation of the stock. In the construction herein shown, periodic operation of the device and periodic circulation of the slush stock from the stock tank to the heaters may be accomplished, this being made possible by virtue of the fact that a portion of the material in the circulatory ferred from the stock tank to the beater tanks for any desired period of time. The structure is such that manipulation of the switch Afagain brings the device to a rest with the valve 16 in a closed condition so as to trap 1 a certain quantity of the slush stock in the pipe line 13.

The shaft of the valve 16 carries devices such as are most clearly shown in Figs. 6, 7, 8

ate a valve motor cut-out switch generally designated B, a pump cut-out switch generallydesignated C and a pump starting switch ienerally designated E, all clearly shown in 1 broken which deenergizes the solenoidJ and the diagrammatic view designated Fig. 2.

' The operation ofthe device will nowbe described with particular reference to Fig.2 with the valve 16in a closedposition and the pump and other-devices in an inoperative condition. To cause the'device to function and create circulation, the operator manipulates the remote control switch A which completes a circuit including the 7 conductor L Zo'terminal F, conductor T through the switch A, conductor G to terminal H of starter box generally designated I, through the coil of a solenoid J, to terminal J and conductor L Closing of this circuit energizes the solenoid J and causes the motor switches diagrammatically illustrated and designated K and also the interlocking switch L to he closed and maintained in this condition. Upon release of the switch A, the circuit just explained is broken,-however, by virtue of the interlock L, another circuit is set up which includes the conductor L terminal M, terminal M conductor M through the normally closed switch B through conductor M to terminal H in starting box I through the coil of the solenoidJ, through terminal J and line L3, it being manifest that while the solenoid J is energized, the switches K and L will be maintained in a closed condition which will cause current to travel through conductors L, L andL through said switches to motorcontacts O which will cause actuation of they r valve motor 18whicli will thus, through the agency of the worm and worm wheel respectively designated 19 and 20 cause the valve to be rotated from its previous closed position to an open position also causing rotation of the various elements shown in detail in Figs. 6,7, 8 and 9 which are secured to the shaftof the valve 16. v

It will henoted that the'solenoid ,coil of the magnetic brake generally designated P is connected through conductors P and P with conductors extending to the motor terminals 0 from those switches K which. are

through the medium of the anti-friction. roll- I ers 24 which are carried by a rotatable element 38 directly connected to worm gear 20 mounted upon the shaft 21 of the valve, which engage the cam 30 of the valve motor cut-out switch B to open said switch. Opening of I the switch B causes the previously established circuit including the conductor L termi-' nals M and M ,conductors M M H, solenoid J, terminal J and conductor L to be vP is simultaneously deenergized, which per I mits the spring 25 shown inFigs, 4t and 5 toact to apply the brakes U to brake drum 22'xand'thus hold the valve in an open position. -Rotation of the valve 16 to open posi tion causes a roller I 26 j 27; toengage the plunger 28 causing depressign and engagement thereof with the push buttonof the pump starting switchfrgenerally tation with'theshaft 21ofthemotor engages the plunger '30 which actuates theswitch B,

designated E closing this switch. v

i The mechanism just referred to is clearly shown in Fig. 9 from which it can be seen that the switchE is momentarily closed when depressed-by the:r0ller 26 which establishes a circuit including the conduetor L ter minal Q of the pump motor starter box X,

conductor Q} through switch E, eonductor Q ythroughthe coil of solenoid Q? to conductor L causing the pumpinotor switches R and'the interlocking switch S te be closed,

this circuit being broken immediately when the roller 26 passes beyond theplunger 28 which allows-the switch Ejto assume itsnormally open position. v l

The interlocking switchS being closed by operation of the switch E, a circuit is established through conductor L to terminal R? throughthe switch S, eonductor R switch C, across to one terminal of switch E through conductorQ through solenoid Q through said solenoid to conductor L By virtue of the; fact that the switches R are at thistime closed,, current will pass from conductors Ll,

L and L3 through theswitches R to theterr minals R of the pump motor 14 which actu ates the motor and pump forthe entire period that the'v'alve 16 is held open. The

' pump motor is actuated'and remains in operation until the operator again actuates;the switch A which will again close this switch and establish a. circuit through the conductor L to terminal F, through ,conductor T, switch A, conductor G to terminal H, through the solenoid J and conductor L This again closes theswitches Kand L, however, as soon as the operator releases the swltch A, this opens the swltch and a c1rcu1t is established through conductor L? to tenni nal M, through interlocking switch L in starting box I, through terminal M 'conductor 1W switch B, conductor M through terminal H, solenoid J to terminal J and conductor L which maintains the coilof the solenoid energized which, inflturmcauses the switches K and the interlocking switch L to be maintained: in a closed condition; The

valve motor 14 is thus eau'sedto be actuated to move the valve to a' closed position, this being, accomplished by virtue "of 'the fact that a circuitis established includii'i'g condnc tors'L L and L through switches "K to terminals of the valve motor 18, and by virtue of the fact that the magnetic brake is connected with eonducors leading to-the" terminals Q otthevalve motor cansesthe magnetic brake to release theho'lclii'ig action of the brake shoes U allowing free rotation orinovement of the valve from an open to a closed position, which movement is'approxi nia-tely ninety degrees opening the switch andc ausing thesolenoid J t o become deenergized, a llowingpthe switches Kand the interlocking switc'hL to open which breaks the circuit to 'the "valve actuating motor 18, again deenergizing the v v magnetic brake generally designated Pfal lowingthe ,spring'25 .tliereofvand other elemnts connected therewith to function to. a

one the rollers31 (FigQB), engages the thei conductors.L R Q R and Q .which jdeenergizes the solenoid Qf; Deene'rgization plunger 32 of'the switch C and opens said witch. IThis" hreaks the rcir'cuit including 5 '1 olfthe solenoiclfQ releases thefmotor-pump switches R and the interlockingfswitch' S Whichbfaks the circuitdincluding the conductorsL L and TL? and; theconductors leading to the terminals It? of the, pump I rendered inoperativefi Thus, the valve16is maintained in 'its inoperative position to ventpumping of slush stock through thelpipe line 13. Manifestly, a quantity of the slush valveivltiflwhich will thus maintain thefstock in a fluid or' semi-fluid stateorin alcondi i tion' in. -which'it'. may be-freadily for'ced motor 14 vcausing the pum metor-ie to be "95 stockisti appedjn the pipe" line '13 above the thro'ugh the pipe line upon subsequent opers f ation of the pump '14 whenthefvalve 16 is again opened. Itis evident that since the stock is prevented against dehydration and is maintained fa fluid or semiffluid state, same may upon'a subsequentoperation of the device, be discharged from jtl1ep1pe-lme,

which'results in permitting periodic instead of constant operation of the 'devicewith a consequent reduction in cost of o eration;

By again referring to F igs; 8 and 9, it will, be noted that the rollers respectively designated=31-and 26 are mountedupon frames suchaslthosedesig nated 27 in Figs.8 and: ,1

Sincethese frames are identicalinlconstruc Y -t i onwith each other, an explanation offone .willsuflicefor anunde'rstandingof both. It will he noted by reference to the structure of the frame 2T that same is directly connected for rotation with frame138, which in'flturn is on the; valve shaft 21; Thef frames 27fare provided with a hub 33and radial'farmsrm spectively designated 34 and 35, thearmsbe directly conneetedtowor'm wheel'2O mounted .7

ingprovidediwith-the arcliate slots 36 which are'providedto'receive a'ca or set'vscrewf37 which are threaded mosh -mme 38. This structure allowsof adjustment-of the frames 27 about the axis of vthe sl' 1aift-2l to thereby arrange the rollers 24, '26' and'31'in various f positions of angularity to thus permit the same tofunction in proper time to accomplish the various objects hereinabov'e referred to. v v w p i By. referring to Figs. 10, 11 and 12, it will be seen that the valve generally designated l and preventing dehydration thereof, the com- 16 contemplates thefutilization of a valve rotatably mounted in a casing, rotation being accomplished through the agency of the '10 worm wheel 20. By referring to Figs. 11 and 12, itwill be noted that the valve per se which is designated 39 has cutting edges such as 40' 4:0 which are provided to cut or shear any of the stock which might become lodged between the valve per se 39 and the casing "of the valve. Fromthe foregoing it-is evident that operationof the motorl l causes slush stock to be pumped and circulated through Y the pipe line 13 and delivered from'the stock tankv 11 to the various beater chests 12, it being understood that this motor is constantly operated to cause circulation of the slush stock in the manner just referred to after the remote control switch A has been actuated to cause the valve to be opened andthat the valve remains in this open condition until 7 the remote control switch A is again actuated'to rotate thevalve 16 to a closed position whichjtraps a portion of the slush stock within thepipe line 13 and maintains same in a fluid or semi-fluid condition or in a condition in which it is-capable of being discharged from the pipe line resulting in the elimination of I the necessity of constant operation of the. ma-

chine to prevent dehydration.
