Description
UNITED STATES PATENT4 Orroac FREDERICK BURGHARDT, OF CURTISVILLE, MASSACHUSETTS.
IMPROVED MACHINE FOR PREPARING WOOD FO THE MANUFACTURE 0F PAPER-PULP.
Specification forming part of Letters Patent No. S7, 139, dated February 23, 1869.
To all whom it may concern:
Be it known that I, FREDERICK BURG- HARDT, of Curtisville, in the county of Berkshire and State of Massachusetts, have invented a new and useful Improvement in Machines for Making Paper-Pulp 5 and I do here-4 by declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanyin g drawings, forming part of this speciiication. v
This invention relates to a new and important improvement in producing paper-pulp from wood; and consists in pulverizing the wood by bringing it in contact with a revo'lv ing cylinder provided with a grating, filing, or rasping surface, and in vibrating the hopper longitudinally, for changing the cutting or rasping surface ofthe cylinder on the wood, and also in a revolving cleaning-cylinder, the whole constructed and arranged substantially as hereinafter described.
.In the vaccon'ipanying plate of drawings, Figure l represents a side elevation'of the machine, showing the cylinder, with-the frame and hopper in section, with the manner of vibrating the hopper, the section being through the line a: a; of Fig. 2. Fig. 2 is a top or plan view of the machine, showing the hopper, the cleaning-cylinder, and the arrangement for vibrating the hopper.
Similar' letters of reference indicate corresponding parts. Y
A is the cutting-cylinder, the surface of which is covered with a rasping, tiling, or grating medium, put on in sections running round the cylinder, as seen in the drawing, or in any other direction or manner, as may be found most advisable.
B represents the hopper, in which the block of Wood to be cut or reduced to pulp is' placed.
C represents the block of wood, shown in red color. The block is simplylaid in the hopper, and rests on the revolving cylinder, by which it is reduced to a fine pulp and discharged beneath the machine.
difficulty I give the block a slow vibrating motion back and forth'on the cylinder. This I accomplish by moving the hopper by means of a Worm wheel, D, and perpetual screw E, the latter being on the cylinder-shaft yF and the former on the shaft G, which is placed at right angles with F, as seen in Fig. 2.
H, Fig. l, represents a cam or eccentric on each end of the shaft G. These cams,as they are revolved by the worm-gear operate on the hopper, and consequently 'on the wood, which lits, or nearly'its, lthe inside of the hopper. by means of the yokes J J, which are attached to the bottom plate, K, of the hopper. In this manner the hopper is given a slow reciprocating motion, and the position of the wood is changed on the face of the cylinder.
L is thecleaning-cylinder, which is covered with card-leather and made to run in contact, or nearly in contact, with the cylinder A, for removing the pnlverized wood from the face of the cylinder. This cylinder is made to revolve at a greater speed than A, and is revolved by a belt from the main shaft l, as seen in Fig. 2.
The cylinder A may be given. any required speed by means of a belt from the motive power on the pulley N.
O represents the frame by which the machine is supported.
The bottom of the hopper slides in grooves above the cylinder, made in raised plates attached to the top of the frame.
By this machine I am enabled to reduce the wood tothe proper consistency for mixing with rag or other paper-pulp for manufacturing white'and other varieties of paper.
Having thus described my invention, I claim new and desire to secure by Letters Patgrating, rasping, or tiling cylinder, substantially as described, or in any equivalent man ner.
3. In combination with the cylinder A, the
cleaning-cylinder L, substantially as and for the purposes described.
FREDERICK BURGHARDT. Witnesses:
JosEPn G. ONEILL, JOHN M. BURGHARDT.
