v point between the-pugging portion and the expressing portion ofthe shaft and contact- I ing with a spiralcarried by the'shaft;

l The invention also has fo'r jan ob ect to pro vide an intermediate bearing means for the shaft ofa straight line combined machine 00- i -actingtherewithin a manner wherebythe shaft may be maintained in desired position v with the pug tub-'and'barrel and which means offers no' hindrance to i,the"desired travel of the material, such as "clay or shale, to the expressing end ofthe shaft.

The outer end of the barrel 1.,has' secured thereto a casting 8 throughwhich the'mat'erial, such as clay or. shale, is fed into the die 4- 1 e0 1 carried by the outer reduced end'of the caste ,isposed axially-of thebarrell andsubstantially central through the tub 2 is a "shaft 5, said shaft extendingfon through for s power application and thrust load. As herein disclosed, the rear end portion of the P TEN O FICETL shaft 5-is connected by a'flexible coupling 6 with an overhanging shaft-7 adapted to be drivenin any desired manner The portion of the shaft 5 within the tub 2 has extending outwardly therefrom the pugging knives8 be termed the expressing portion ofthe shaft,

a spiraljS). This spiral9'togetherwith the has mounted thereon for rotation therewith shaft' 5f extends within thec'a'sting 3V and by an extension spiral 10 which is disposed along theportion of the shaft 5 between the c pug portion and the expressing 'portlon of terminatesclosely'adjacent to the outer end I The inner end of the spiral 9 is continued the shaftand theperiphery of'said extension spiral 10 is provided with ajrelatively wlde,

rim 1 1 t e-provide an increased'bearing sur face. The extension spiral 10 may also be will hereinafter, be apparent, and in the,

present embodiment of my inventionsaid extension orsupporting spiral 10 is insertedin the forward end portion of the'tub 2 or that portion of the tub Qimrnediately adj aeent to i the barrel 1;

The forward end portion of thetubi2gis Q provided in its lower wall with a series of s termed a supporting spiral'for reasons which elongated slots lspaced apartin a direction circumferentially of the shaft 5 and immsi T diately below theextension or supporting tively broad supporting surface with which" the rim 11 of the extension or supporting spiral 10 directly contacts, thus assuring the shaft 5 being effectivelymaintained in desired working "position with respect "to the barrel 1 and the tub '2.

Engaged over the outer rear marginal portionrofeach of the blocks 15 is elongated member 16 of metal or other desired material and "which is provided in its inner. face with a pocket 17 which snugly receives the outer marginal portionof the block 15.

, Extending-outwardly from the wall of the tobQ closely adjacent to the opposite ends of, aslot 14 are-thethreaded shanks 18 which are freely disposed through the" extremities ofthe members-16L Threaded 'upon said shanks 18 and contacting with the outer face a of the associated member 16 are the adjust-' ing nuts 19. By requisite turning movement ofthese nuts 19 the'adjaeent meniberldand associated block 15 will beforced inwardly ofthe tub 2 to compensate for such wear as may occur in connection with eitherthe block 15 or the spiral-10 or both; thus assuring maintenance ofthe: shaft 5 in desired worle ing position: -The extension or "supporting spiral 1O permits an unobstructed travel of the material, such as clay or shale within the barrel :1 foriexpr'essing action by the Spiral 7 1 9 andthe portions-ofthe blocks '15 disposed within the tub 2 serve as additional ribs which, in connection with the ribs 20disfposed along the inner-faces ofthe barrel 1 and casting-"3, will hold the material under pressure? against revolving or. rotating with the spiral: o

It is to be jn'ot-ed that the bearing blocks 15 are sethighe'r on one side than on theother and thus offsetting-any tendency of the sup plementa-l or supporting spiral 10 and the adjacent port-ionof the shaft 5 to movelat orally When'the spiral 10 is inrotation. In

this is preventedjby providing the higher block15. Infact, it isof advantage to have {the uppermost block to the right of the spiral I '10positioneid above the horizontal center of such-s iral a I In the embodiment of the invention as illnsftratedin Figure 4,:the extension or siup- Q'p'ortiirg' spiral' 10" has contacting therewith the bearing rollers 21 to: maintain the desired positioning of' 'the shaft '51,
