FRANCIS SHELDEN, OF FITCHBURG,
MASSACHUSETTS, ASSIGNOR TO THE UNION MACHINE COMPANY, OF SAME PLACE.
Letters Patent No. 104,781, dated Juno 2S, 1870.
IMPROVEMENT IN APPARATUS POR BLEACI-IING PAPER-STOCK.
The Schedule referred to in these Letters Patent and making part of the sannek tubular lifter, andan adjustable spray-deector, with a kier, kettle, or cistern, and a pipe for the introduction of steam into the central part of the bottom of such cistern, there being also combined with such parts or devices mechanism for moving the spider, the lifter, and spray-valve together and vertically within the kier or cistern, as circumstances may require.
0f the drawingr above mentioned.-
Figure 1 is a front elevation;
Figure 2, a vertical section and Figure 3, a horizontal section of the said apparatus.
In such drawing- A denotes the kier, tub, or eistern` for holding the stock or pulp to be bleached, and the liquor or chemical material, or matters used in carrying on the bleaching process.
A` pipe, B, for the conveyance of steam, passes ythrough the side, or other proper portion of the lower part of the 'cistern, and terminates at or above the center of thebottom thereof, the said pipe, at its inner end, being, open, and directly beneath the` month or open lower end of a stand-pipe, C.
This conduit C is fastened, at its lower end, to a metallic spider or frame, D, having a strainer, or foraminous top, or flooring, a, whose diameter is about equal to that of the inner part of the tub.
Extending diametrically across the upper end of the.
pipe C isA a bar, b, down into which a screw, c, provided with a concavo-convexl head, ll, is screwed. The said head has a diameter about equal to that of the pipe C, and serves as a spray-dedector. Furthermore, a shackle, E, is pivoted to the upper end of the pipe C, and receives a hook, F, extended from a vertical screw, G.
The said screw passes through the upper girt of a `frame, H, formed and arranged with respect to theA kier or cistern, in manner as represented.
' A nut or beveled cogwheel, I, resting on abearing at the top of the frame, screws upon the screw, and engages with a beveled pinion, K, carried by a drivingshaft, L, the whole being as represented 1n the drawing. 4
By revolving thev screw, the foraminous spider, with its stand-pipe, may be either raised or depressed, relatively to the cistcrn or kier.
In the operation of the apparatus, after it may havebeen charged with the material. -to be bleached, and the liquor and substances or matters used in effecting the bleaching of it, steam is supposed to flow into the cistern and directly into the stand-pipe. It will blow the liquor in such pipe up against the deflect-or, by whichit will be deflected radially from the pipe, and upon-the top of the charge, after ebullition of the `liquid and the pulp may have been carried ou a sufficient time by the steam so applied to the platform, and thc pulp thereon may be raised out of the cistern,
and from the bleaching-liquor thereof, thereby saving such liquor for being used on another charge of pulp. `Heretofore it has been customary to open a vent in the side of the bleaching-cistern, and allow the escape ot' all the spent bleaching-liquid before removing the charge of pulp from the eistern. By my process I save the said liquid.
claim as'my invention, in the apparatus as above described, the following, viz:
The elevator, as composed of the ihraminous platform, and the tubular stand-pipe.
-Also, the arrangement and combination of the adjustable delector with the stand-pipe, and the foraminous platform.
Also, the combination and arrangement of the foraminous platform, the stand-pipe, and the deflector, with the kier or cistern, and its steam induction-pipe, the stand-pipe, and platform having mechanism for moving them relatively to the delector, and the whole being substantially as and foi-'the purpose, and to operate as specified. l
