To ctZZ whom it may concern.-
Be it known that I, ALFRED WELLS CASE, a citizenof the United States, residing at Highland Park, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Beater-Engines, of which the following is a specification.
This invention relates to those machines which are built for the purpose of beating and macerating or shredding fibrous material into pulp.
The beater which forms the subject of this invention is particularly designed for beating scrap-leather into pulp, although it may be used for beating other materials.
Scrap-leather contains more or less greasy matter and lumps or bunches which are not easily macerated or shredded. To form good smooth leather-board, the pulp must be uniformly beaten and all bunches and matted portions broken up. \Vith the ordinary beater to insure uniform density and absence of lumps the entire mass must be beaten until all of the stock is completely reduced, although, of course, most of the mass will he reduced before the lumps are reduced.
The object of this invention is the production of a beating-engine which is so constructed that the material which is to be beaten can be continuously fed into the tub and the stuff as it is sufficiently beaten can be continuously removed, thus effecting a saving of energy and time, besides insuring a uniform product without nubs.
The heater which is illustrated in the accompanying drawings as embodying the invention has a tub with a common vertical mid-feather, bed-plate, backfall, beating-roll, and picker-cylinder, that is partly submerged in the stock in the tub, so as to pick up and throw such stuff as is properly macerated or shredded onto a traveling apron, which trans fore the stuff to a stockyat or other desired receptacle.
Figure 1 of the views shows a plan, with the cover removed, of a beating-engine that embodies the invention; and Fig. 2 shows a side elevation, with part in section and the driving-pulleys omitted, of the same engine.
The beater illustrated has an oblong tub I of ordinary shape and dimensions. In the center of this tub is the usual vertical midfeather 2, on one side of which is the bed 3, with bed-plate 4and the backfall-5 of common design. The posts 6 support the adjustable lighters 7, which carry the bearings that hold the shaft 8. Upon the-shaft, over the bed between the mid-feather and one side of the tub, is a common beater-roll 9, and outside of the tub on the shaft-is a driving-pulley 10. The lighters are so supported that the periphery of the beater-roll may be ad j usted with relation to the blades 11 of the bed-plate beneath the roll, as usual. On a shaft 12, held by bearings secured to the walls of the tub and provided with pulleys l3 and 14, is a cylinder 15. The periphery of this cylinder is arranged to dip into the stuff in the tank and is provided with fine teeth 16, thatwill pick up fibers from the stuff. On a shaft 17, arranged across the Walls parallel with and adjacent to the pick-up-cylinder shaft, is a cylinder 18, that is provided with fine teeth 19, the points of which preferably project between the teeth on the periphery of the pick-up cylinder. 0n the-shaft 17 is a pulley 20,that may be belted to a pulley 21 on the beater-roll shaft, and a pulley 22, that may be belted to the pulley 14 on the pick-np-cylindershaft, so that the pick-up and break-up cylinders will rotate in the same direction. break up the matter picked up by the pickup cylinder and prevent nubs and hard lumps from being carried up and thrown off as the cylinders rot-ate.
Held by bearings arranged adjacent to the end of the tub are the arbors of rolls 23. One arbor is provided With a pulley 24, which may be belted to the pulley 13 on the pick-up-cylinder shaft, with which these rolls are parallel. An endless apron 25 passes around these rolls. This apron is preferably made of an open mesh material and is provided with cleats 26. At the outer end of the apron is a stock-tank 27, with a discharge-pipe 28.
The pick-up cylinder is rotated with such speed that it picks up the fine fiber that has been sufficiently beaten and is floating near the surface of the stuff in the tub and throws it onto the traveling apron, which deposits it in the stock-tank. From the stock-tank the properly-beaten stuff may be drawn oft discharge-pipe to any vat or ma through the The teeth on the break-up cylinder chine. Of course the apron could deposit the in;a large savin-g 1 is .not necessary finished while the .unfinished stud directly. onto the apron of apaperor board machine, and if desired the apron can be dispensed with, in which case the pick-up cylinder can be arranged to deposit stuff directly on a paper-machine apron or into a vat.
A cover 29 is arranged over the pick-up cyl-'- inder and inner end of the conveying-apron, so that the material which is thrown by the picker will fall upon the apron. Surplus water which is thrown up with the stuff drains backinto .the tub. By means of this simple until allot the mass 1s properly reduced, for
that .which is finished may be taken away as it is completed, leaving only the .unreduced part to be beaten. This method results to agitate the part which is reduced, and it is not necessary to wait until the unfinished part-is reduced before using .macerated can the beaten stuftis removed, so that the mathestock. Furthermore, the substance to be be fed in .from time to time as chine maybe run continuously. This is par- ,ticularly advantageous when beatingleatherstock,.for the reason that such stock contains hard hubs and greasy lumps,
much time and power to reduce, and unless .the. entiremass is reduced evenlythe finished productwill be imperfect.
-. I claim as my invention- -'1. In.combination with the tubof abeating-engine, a pick-upcylinderadapted to-be rotated .with .a part .of its periphery submerged in the stock in the tub, and a breakup cylinder locatedadjacent :to the pick-up cylinder, whereby finished stock will .be picked up and thrown from the tub and unfinished stock returned to the tub, substantially as specified.
2. .In combination with the tub of abeatof time and venergy, .for it.
part is being which take ing-engine, a beater-roll, a pick-upcylinder with fine-teeth adapted to be rotated with a portion of its periphery submerged in the stock in the tub, means for rotating the cylinder so that it will pick up and throw off finished stock from the tub, an endless conveyerlocated with a portion adjacent to the pick-up cylinder and means for moving the conveyor whereby stock deposited upon the conveyer by the pickup cylinder is con.- ducted away from the tub, substantially as specified. v
3. In combination with the tub of a beating-engine, a pick-up cylinder adapted to be rotated with a part of its periphery submerged in the stock in the tub, a break-up cylinder located adjapentto-the pickrup cylinder, and a conveyer located adjacent to thepick-up cylinder for con-ductingawaystocklwhichzis deposited on it by the pick-up, cylinder, sub= stantially as specified.
