Application June '26, 1934, Serial No. 732,445 .5 la ms- 9.2-.-24

This invention relatesgenerally to the pulpand paper industry, and particularly to .a heater.

The main object .of this invention is the provision of a new form of beater inwhich is incorporated a mechanical means for positively circulating the precipitated materials between the beater roll and bed plate, thereby eliminating any necessity for manually inducing the circulation of the unbeaten materials. I

The second object is .to expedite the beating operation by reducing the amount of hand labor required, the amountof power consumed, and the amount of time required.

The third object is to improve the quality of the stock by thoroughly separating all of the fibers without over-beating portions thereof and thereby shortening the fibers, as is commonly the case where no positive circulation is provided.

These, and other objects, will become more apparent from the specification following as illustrated in the accompanying drawings, in which:

Fig. 1 is a plan of the beater.

Fig. 2 is a side elevation of the beater with portions broken away in vertical section.

Fig. 3 is a section taken along the line 3-3 in Fig. 2.

Fig. 4 is an end elevation of the beater.

Fig. 5 is a section taken along the line 5-5 in Fig. 2.

Similar numbers of reference refer to similar parts throughout the several views.

Referring in detail to the drawings, the tub consists of a bottom 10, side walls 11 and end walls 12, all of which may be made of any suitable material such as wood or iron. In the corners between the end walls 12 and the bottom are placed the fillets 13. In the chairs 14 is mounted the bed plate 15.

Between the side walls 11 is the inclined runway 16 whose lower end 1'7 extends almost to one end 12, while its upper end 18 extends well over the top of the side walls 11. A chute 19 connects the uppermost end 18 with the bed plate 15. On the lower end 17 is secured the brackets 20 across which journals the shaft 21, near the ends of which are mounted the sprocket wheels 22.

Mounted on the side walls 11 are the standards 23 which carry the transverse shaft 24 on which are pivotally mounted the blocks 25 which, in turn, support the side frames 26. The frames 26 are joined by the cross ties 27 which also serve to support the motor 28, by means of which the beater is driven.

The opposite ends 29 of the side frames 26 are united by the cross tie 30 under which is placed a m nua ly ope a ed h draul c Jack 1 "WhQS? ow m s po t on li it t d w war ovi m o hef m endsfla us y. s op may PIQViQQd n s d wall .1. tha h s tt n o th fram 6 may b e a -w t ext em precisio u n ed om th l rame .26 ar ihebea t n in ich Jour l h beater .1 t., 3 ,Q Q1 end of ic is a Pulle 5: ,pror dedw t ahel 3.5 wh h a e a o ndth hulleyifi Q th mew 9. th ha 3 i .m'purted theta ate 1.9. 7 which may b f e time newin than The side walls 11 are provided with cut-out'portions 38 to receive the bearings 32.

Across the side frames 26 is mounted a counter shaft 39 on one end of which is loosely mounted a sprocket wheel 40 whose chain 41 passes around the sprocket wheel 42 which is secured on the beater shaft 33. A driving connection between the shaft 39 and the wheel 40 is obtained through the clutch 43, under the control of the hand wheel 44, or by any other convenient means.

On the shaft 39 is secured a pinion 45 which meshes with the gear 46 on the conveyor drive shaft 47 which journals in the bearings 48 on the side frames 26. On the shaft 47 are secured the sprocket wheels 49 which are in alignment with the sprocket wheels 22.

Around the sprockets 22 and 49 are passed the conveyor chains 50 on which are disposed the transverse flights 51. The chains 50 are sufficiently loose so that their downwardly descending runs hang vertically into the tub so that there will be an accumulation of slack near the end thereof, as shown. This is essential as it contributes largely to the complete movement of the precipitates toward the opposite end of the tub, where they are picked up and carried over the runway 16 and delivered to the beating elements 15 and 3'7.

It is a well known fact that in operating a machine of this kind it is desirable that the engaging faces of the elements 15 and 37 be in close contact at all times without actually wearing upon each other, in order that the maximum amount of efliciency be obtained in the beating operation.

Assuming this to be the case, with the use of my mechanical circulator it is now possible to cause the stuff to pass in a continuous stream through the beater until all of the fibers are completely separated.

In order to prevent the splash of the stufi 52 over the sides of the tub there are provided bed plate disposed within said tub, a frame hingedly mounted over said tub, a beater drum mounted on said frame above said bed plate, means for elevating said drum and its supporting frame away, from said bed plate, an incline disposed in said tub constituting an approach to the bed plate, and a conveyor adapted to move along the bottom of said tub and to carry precipitates up said incline to said bed plate.

2. A beater having in combination a tub, an inclined floor mounted in said tub whose lowermost end is near one end of the tub and whose uppermost end extends above the upper sides of the tub between the ends thereof, a chute extending from the upper end of said inclined floor sloping in the opposite direction therefrom and having a bed plate at the bottom of the chute, a hinged frame mounted over said tub including a revolvable beating element, a conveyor adapted to pass entirely around said inclined floor, chute and beating element having its lower run resting upon the bottom of the tub and having its upper run resting upon said inclined floor, the descending portion of said conveyor hanging substantially vertical and having suflicient length to provide an accumulation of conveyor mechanism at the end of said tub from which precipitates are drawn.

3. The substance of claim 2, and means for raising said hinged frame for the purpose of separating said beating element from the bed plate.

4. A beater having in combination an elongated tub having a rectangular frame hingedly mounted above same, said tub having an inclined floor therein the lower end of which extends toward one end of said tub and spaced therefrom while the upper end thereof extends above the sides of said tub and terminates 'in a downturned chute, a bed plate disposed transversely across said tub at the lower end of said chute, a cylindrical beating element disposed over said bed plate and supported by said frame, a conveyor having its lower end passing through the space between the lower end of said floor and the tub end and having its upper end mounted on said frame in a manner that said conveyor shall. move along the upper side of said floor while its downwardly traveling portion is substantially vertical, said conveyor having sufiicient looseness to permit an accumulation thereof at one end of said tub from which point it is drawn along the bottom of the tub and carried up over the inclined floor to the heating element.

5. The substance of claim 4, and a hydraulic jack for raising the conveyor end of said frame for the purpose of elevating said beating element away from said bed plate.
