PRESS-ROLL.
Specification of Letters Patent.
Patented Oct. 3, 1905.
Application filed January 30, 1904. Serial No. 191,284.
Beit known that I, KIMBALL B. FLETCHER. a citizen of the United States of America, and a resident of Lancaster, in the county of Coos and State of New Hampshire, have invented certain new and useful Improvements in Press- Rolls, of which the following is a specification.
This invention relates to press-rolls of pa per-machines, and especially to press-rolls employed in the wet-press part of such machines and the press part of the wet-pulp presses of wet machines. Heretofore these rolls have usually been made by being turned into a cylindrical form from a solid log or block of wood. The growing scarcity of suitable material for this purpose and the fact that any injury to the surface of the roll either by unequal wear or otherwise makes the whole roll worthless often renders this form of construction an expensive one. Moreover, the rolls as used are of considerable size, and it is becoming practically impossible to secure logs large enough from which to construct rolls of the size desired. Again, in transportation the rolls as heretofore constructed are liable to become damaged, which necessitates the turning down of the cylindrical roll, thereby greatly decreasing the life of the roll, which it is obvious is very objectionable. To obviate all of these difliculties is the aim of the present invention; and it consists, substantially, in dividing the roll into numerous small sectors of wood arranged in layers and interlocked and attached together by suitable means whereby the use of cheaper material is made practicable, and in case of injury to the surface of the roll the injured portion can be removed and replaced without losing the rest of the roll.
It further consists in making the roll in sections, each section being constructed of numerous disks or sectors of disks of wood.
Moreover, it also consists in certain novel features of construction and arrangement of parts, which will be readily understood by reference to the description of the drawings and to the claims to be hereinafter given.
Of the drawings, Figure 1 represents a front view of the finished roll. Fig. 2 represents an end view. Fig. 3 represents a cross-section. Fig. 4 represents a longitudinal section. Fig. 5 represents a front view of one of the sections of which the finished roll is composed, and Fig. 6 represents a view of one of the sectors of which the sections are composed.
Similar characters designate like parts throughout the several figures of the drawings.
In the drawings, 10 is a central shaft, preferably made of iron or steel, provided at either end with gudgeons 11. Near either end and intermediate said gudgeons are splines 12, in which are mounted keys 13, by which the circular plates 14 are keyed to said shaft and prevented from turning thereon. The plates 14 have a movement longitudinal of the shaft 10, and between said plates are a plurality of sections 15 of substantially the same diameter as said plates 14:. The sections 15 are secured together and to said plate 14 by means of the rods 16, extending longitudinally through said plates and sections and provided with nuts 17, mounted on the threaded ends of said rods and by which the plates 1A may be drawn together to clamp the sections 15 together and to the plates 14, thereby preventing their movement about the shaft 10 and causing the roll formed by said plates 1A and sections 15 to revolve with said shaft.
Each section 15 is composed of a plurality of layers of wood, each layer being composed of a plurality of wooden sectors 18. Each sector 18 is made with its grain substantially radial to the axis of the shaft 10 and is provided with interlocking means 19 to look all of the sectors of a layer together to form a disk, the grain of wood of said disk radiating from the axis of said shaft.
In making up a section 15 the various disks made up of sectors 18 are placed together so that the joint between said sectors will be intermediate the joints of the sectors in the disks next adjoining, so that all of the sectors throughout a section will overlap each other. The various disks of a section are secured together by nails or other suitable connecting means. It is immaterial whether the disks are made of thin veneer interlocked and connected together or of boards or planks, the principal object being to be able to use cheaper material and small pieces which can readily be secured in good stock and to make a pressroll which will be much more durable, having the grain of wood of which it is composed radiating from the axis of the shaft, than the rolls heretofore used, where the grain necessarily ran lengthwise of the shaft.
Another object of this invention is to provide a ready means of transportation by making up the roll in sections, which can easily be transported from place to place without injury, and when a portion of the roll has been injured or worn down suliiciently to necessitate replacing the section may be removed from the shaft and replaced by another without losing the remainder.
\Vhile wood is preferable in the construction of this roll, other materialsuch as leather-board, vulcanized fiber, &c.---may be used in their place. in case the renewal of the whole roll is necessary the sections required to form a new roll may be sent by the manufacturer and be put on the shaft at the mill where the roll is used without removing or sending away the shaft.
Having thus described my invention, 1 claim- 1. in a press-roll, the combination of acentral shaft, a plurality of units each unit being formed of a plurality of disks made up of sectors of wood secured together, a metallic plate keyed to said shaft near either end, and means near the periphery of said units for drawing said plates toward. each other to hold said units in position.
2. In a press-roll, the combination of a central shaft, a plurality of units each unit being formed of disks made up of sectors of wood secured together, a metallic plate keyed to said shaft near either end, rods extending longitudinally through said units and plates, and adjustable means mounted upon said rods for drawing said plates together to hold said units in position.
3. In a press-roll, the combination of a central shaft, a plurality of units each unit being formed of disks made up of sectors of wood secured together, a metallic plate keyed to said shaft near either end, rods extending longitudinally through said units and plates, and nuts mounted upon said rods for drawingsaid plates together to hold said units in position.
4. In a press-roll, the combination of a central shaft, a plurality of units made up of disks formed of sectors of wood interlocked, a metallic plate keyed to said shaft near either end, rods extending longitudinally through said disks and plates, and means mounted upon said rods for drawing said plates together to hold said disks in position.
5. In a press-roll, the combination of a central shaft, a plurality of units each unit being made up of a plurality of disks of wood secured together, a metallic plate keyed to said shaft near either end, rods extending longitudinally through said units and plates, and means mounted upon said rods for d rawing said plates together to hold said units in position.

7. In a press-roll, the combination of a cen* tral shaft, a plurality of separate units upon said shaft each unit being composed of a plurality of disks independently secured together, a metallic plate near either end of said shaft, a plurality of rods passing through said units and plates, and nuts on either end of said rods for drawing said plates toward each other to clamp said units in position.
8. In a press-roll, the combination of a plurality of units, each unit being composed of a plurality of disks permanently secured together, a plurality of rods passing through all of said units near their periphery, a metallic plate at either end of said roll provided with openings through which said rods pass, nuts threaded to the ends of said rods and adapted to bear against said plates to clamp the units together, and trunnions in axial line with said. disk units upon which said roll may be clamped.
9. In a press-roll, the combination of a central shaft, a plurality of separate units upon said shaft each unit being composed of a plurality of disks independently secured together, a metallic plate near either end of said shaft, means for preventing the rotation of said plate upon said shaft but permitting longitudinal movement thereon, a plurality of rods passing through said units and plates, and nuts on either end of said rods for drawing said plates toward each other to clamp said units in position.
