Application md June `23, 1924. sriaino; 721,850;

'Theobject ot my inventionis'to provide improvements inmechanisms for preparing and working clay in the nature of a continnous` pugging wet pan adapted to yfeed the pugged material'to one or a number of tile machines simultaneously.' v

A further object is to providean improved puggingI mechanism so arranged that the clay or shale to be pugged may be worked intermittently, as I iind this has considerable `advantage in giving the material more time to thoroughly mix with the water, and at Cal the same time enable the device to be operated more economically from a power standpoint, the object being to pug or agitate the material for a short time, then :permit it :to rest for a' shorttime while the moisture. is being absorbed by the drier portions of the material broken up by 'the pugging action, thereby saving-a ,considerable power over "the Continuous methodot` pugging.

Afurther object is'tol provide in such a device, means whereby a series of tilev machines may bev simultaneously fed from thewet pan I `of the pugging mechanism, each of'said tile machines being adapted to be'independently thrown into and ont of operation relative to said pan, and cachot said tile machines being operatively connected with an independent pugging apparatus including a water supply, the last said devices being `so constructedand arranged that as the tile machine isthrown out of operation, the said water supply 'and pugging lapparatuswill also ybe thrown out of operation. l

A further Objectis to'provide means 'for automatically controlling the amount of water ted tothe mixture within the pan..y

A further object is to provide in -connection with such a device, that type of atile machine having continuously operated wire cutters, and lin connection withV said wire cutters, meanswhereby, it one of the cutters should become broken, the tile machine together with its pugging unit will be automatically thrown out ot' operative relation with the pugging pan.

A further object is to provide in a pugging mill an improved blunger knife. y y

My inventionconsists in the construction, arrangement and combination ot' the various parts of the4 device, whereby lthe objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which f Y y vFigure 1 is a plan View of aseginental p'or-L j i tion of my `improved device.

lan electric magnet 5() having a sliding core 51, one end .of said corebeing,` pivotally` connected to the sector42. This -provides'means whereby the, plow/may be liftedby establishing an electric circuit through the magnet 50, thepurposefof. which will hereinaifterbe A `switch device 52 is also pro-vided inthe casilrggv` comprising a bracket 53'having a; sationary contact'member 54 and a movable Contact. member 5 5. This member 55 is actuated by means of a pivoted lever 56, the lower endl of which is designedto engage thelug 43 when the plow is in its inoperative position, thereby causing;` t-he switch member 55I to disengage theV switch member 54, through the action vofa coilspring 57. A;

spring 58 is providedv for movingfthe switch ydev1ce-55to its closedposltion. The` switch 52 visf includedminr circuit hereinafter des: scribed. v 1 l The pan. is, also provided with a .number of mullcrwheels 59, leach of which mounted on a shjaft 60 each oisaidshafts being sup-y ported in .pivoted arms 6l.- The said arms 61l are carri-ed by.` a shaft 62 mounted in suitable brackets 63and r64.v The axis 60-is also-ar- Each ofthef.

. shaft 12.

ranged substantially radially with the Adjacent to one side of'each ofthe mullers y59 is a vvertically arrangedv waterl supply pipe 65, theV lower end of each of said pipes. b-eingprovided witha control 'valve 66, eachofisaid valvcshaving a .stem 67 operated through a bell crank l-ev-er 68.` One end of the bell cranklever 68 is provided,

.with-amagnetcore 69 designed to slide in the electromagnet 70. A spring 71y is pro `vided for holding the core 69to its. outer.

limit of movement, and also for closing the valve 66. r

Each of thebraclrets 28 is provided with' aforwardly extending portiony 7 2, to. which is pivoted a' scraper blade7 3, the saidV blades being design-ed to extend inwardly and forwardly adjacentto the top face of the table 13,- so that as the said table is rotated, material thereon will bejscraped 'into' the' pan.

`A rod 74 is pvoted-near the pivot .end of each ofthe members 7.3, and is designed to extend out-wardly into the casing 38.v :The outer end of said rod 74 is pivoted to the sector42, as clearly shown 'in Figure 4.

By this arrangement, it will beseenthit as the plow l42 is elevated, the rod 74 will be movedoutwardly, which` in turn will cause the scra er 7 3 to be swun0-outwardl from the table 13, thereby providing means whereby the feeding of the material ,to the pan will be automatically cut off..

I have provided in the rod 74 a turn buckle 'ofthe piowio. 1

Pivotally mounted adjacent to the front side of the hopper 37 is .a shaft 7 7, the inner end of which is provided with a crank wheel 78 having a crank pin 79 designed tofcarry a connecting rod 80, the lower end of which is pivotally connectedto upwardly extending Y lugs 81 from the free end of the packer 76. Thus it will be seen that if the shaft 77 is rotated, the free end of the packer will ybe elevated and lowered, which will cause the pugg-ed material to be packed ahead of the plow, so as toform a lsort of stiff column of clay, which may be easily and readily slid upwardly andfoutwardly over the face ofthe plow into the hopper 36, which lwould be almost `impossible'if the materialwere loose at the time it engagedlthe plow.

The shaft l77. is l driven Ifrom an electric motor .82 and worm gears 83.

The inner. end of eachof'the'speed reducing gear members 30 is provided with an annular contact ring 84, which is insulated from the lcasing of the speed reducer, and designed to form one terminal of an electric circuit. The annular member 84 is provided with a segment 85 mounted on Vone end of a slidable shaft 86, so arranged that as the said shaft is moved longitudinally, the

sector. 85 will be moved into and out of positionin the annular ring 84, and when in position forms a partof the contact. I

Mounted on the shaft 29 is a hub 87 having an outwardly 'extending arm 838, the said arm beingfprovided with a pivoted contact member 89,. which vis heldoutwardly by means of a spring 90, and into contact with the members 84 and'85. The purpose ofthis l will hereinafter be made clear.

in Figures e and 9, i have illustrata the cutter reel of the tile machine,which comprises an axle 91'havin'g a spider'92 designed to carry aV series of pivoted cutting arms93, each of said arms being provided with a cutting wire 94. The said wire 94 is mounted in insulatedy supporting members 95, 96 vand 97. The members 96 and 97 are electrically'l connected. by conductors 98. z One :of `the members 98 is connected with a rslip ring 99,

which is insulated fromthe 'Spider 92. A

contact member 100 is providedl for said ring, which is connected toav conductor 101 of an electric circuit. f

Thus it will be seen thata-n electric cir,-

cuit may be established lthrough the con-l ductors A98 and the cutting wires 94,v and the opposite one of the members 98 being grounded to the spider 92,`which in turn is groundedto the conductor 102. l It will be seen that if any one of the wires94should become broken, then the circuit maintained in the conductors 101v and 102 will bey tors 105, 103 andw108, `together withl the switches 104 and 107, provide means whereby an electric' current may be vsupplied from any suitable power plant for the operation of the motors' and' electric' mechanism of my improved device.

The. conductor 101 has included a y coil 109, said relay ,being provided with a contact included in'an electric conductor 111 connected with thefconductor 10.3.

JIU!" The conductor 111 is connected-at oneside y o f the plow operating magnet 50, while they ,Y

otherl side of the magnet 50 leads to the* switch member 54, while the switch member'- 55' is provided with a'conducto-r 112 lead-` ing to the conductor 108; f

Thus it will be Seen'that when the ciitter wires'94 are placedinposition, and the 1 switches 104 and 107 fare closed, a current will flow through the said cutter wires'94.

and through the relay coilv 109, vwhichr is preferably of high resistance, so thatV aY small amount of current is consumed. This will cause the switch device 110 to be nor- 'y mally held open and the plow will then be free to drop into position'within the pan when the control rod 48 has been operated',

but if one of the wires 94 should 'become' broken, then the switch lever`110 will be released -from the coil '109 and-,a circuit 130 established. through. the.. conductor'. 111,
