REFiNme-ENeiNe SPECIFICATION forming art of rates Eatefit No. 650,738, dated my 29, 1906. Application filed July 21,1899. Serial No. 724,622. (No model.)

To all whom it 71mg concern: v

Be it known that 1, CHARLES EVERETT'TOR- RANGE, of Northampton, in the county of Hampshire and State of Massachusetts, have invented a new and Improved Refining Engine, of which the following is a full, clear, andeiiact description.

The invention relates to paper making machinery; and one object is to provide a new and improved refining-engine arranged to permit convenient, quick, and accurate adjustment of the shell and revolving plug without disturbing the position of the plug and the driv ing-gear, so that the latter always remains jn true alinement with the overhead countershaft pulley; and a further object is to allow the removal of the plug and shell whenever deemed necessary for repairs and other purposes and without disturbing the drivinggear.

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claim.

A practical embodiment of my invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a plan View of the improvement. Fig. 2 is a longitudinal sectional side elevation of the same approximately on the line 2 2 of Fig. 1, and Fig. 3 is a transverse section of the same 011 the line 3 3 in Fig. 1.

A suitably-constructed bed-plate A is provided with longitudinally-extending guideways 13, in which are fitted to slide flanges O, projecting from a shell 0, in which ismounted to rotate a plug D, secured on a shaft E, journaled at one end in a thrust-bearing F, supported on the bed-plate A, and the other end of said shaft is connected by a suitable coupling G with a driving-shaft H, carrying a driving pulley H, connected by belt with other suitable machinery, such as an overhead counter-shaft pulley for imparting a r0- tary motion to the driving-shaft H, the shaft E, and the .plug D. The driving-shaft H is journaled in suitable bearings I, attached to the bed-plate A, as is plainly indicated in the drawings.

The shell 0 is provided with the usual 1in- C and the plug D is provided with :the uslial bars or cutters D, and said shell 0, as well as the plug D, is preferably made in the form of a fr stum of a cone, as is plainly indicated in l ig. 2. The heads 0 O of the shell 0 are provided with stuffing-boxes J J, respectively, through which passes the shaft E, and the head 0 closes the receiving chain; her or throat C of the shell; The throat C is provided oh. the top with a receiving-pipe K, through which passes the paper stuff int-0 said throat C and from the latter to the plug D and shell C for treatment by the revolving plug. The bottom of the receiving chamber or throat O is provided with a collecting-box C for hard substances to settle in to prevent injury of the bars D by such substances; The latter are discharged from time to time from the collecting-box by means of suitable pipes 0 In order to adjust the shell 0 longitudinally relatively to the plug D to compensate for wear of the bars D, I provide the following device: On the outside of the shell 0, preferably at the lower part thereof, is arranged or formed a nut 0 in which screws a screw-rod L, mounted to turn in suitable bearings arranged on the bed-plate A. On the outer end of the screw-rod L is secured a worm-wheel N in mesh with a worm N, secured on the lower end of a vertically-disposed shaft N journaled in suitable bearings on the bedplate A and provided at its upper end with a hand-wheel N under the control of the operator. When the, wear on the bars D has been such that adj ustment is required to bring the bars in proper relative position to the inner surface of the lining 0 then the operator turns the hand-Wheel N to cause the shaft N and its worm N to turn the worm-wheel N and the screw-rod L and move the shell 0 longitudinally in its bearings B in the direction of the arrow at until said lining O is again in proper relation to the outer or peripheral surface of the cutters or bars D.

When it is desired to remove the shell and the plug D, together with its shaft E, for repairs or for other purposes, it is only necessary to disconnect the shaft E from the thrustbearing F and loosen the coupling G to disconnect the shaft E from the driving-shaft H. The plug can then be drawn out of the shell, and, if desired,the latter can be removed from its guideways B on the bed-plate A.

In the head C preferably at the bottom thereof, is arranged an outlet-pipe 0, having a slidable connection in a discharge-pipe P, carried by the bed-plate A and leading to a suitable place of discharge.

By reference to Fig. 2 it will be seen that when the shell 0 is shifted in the direction of the arrow a, as above explained, then the discharge-pipe O is free to slide in the pipe P without disconnecting the two and Without requiring any attention Whatever 011 the part of the operator.

Having thus fully described myinvention,

pipe slidably inserted therein, as and for the 30 purpose set forth.

CHARLES EVERETT 'lORltANCE.
