IMPROVEMENT IN PAPER-CALENDERING MACHINES.
Specification forming part of Letters Patent No. 187,586, dated February 20, 1877; application filed.
September 22, 1876.
To all whom it may concern Be it known that I, FRANCIS W. BIRD, of East Walpole, county of Norfolk, and Commonwealth of Massachusetts,have invented certain new and useful Improvements in Paper- Calendering Machines; and I do hereby declare that the followingis a full, clear, and exact description of the same, reference being had to the accompanying drawings, and the letters of reference marked thereon, forming a part of this specification, and in which Figure 1 represents a top or plan view of inyimproved paper-calendering machine. Fig. 2 represents a side view of the machine, looking in direction of arrow 1, Fig. 3. Fig.3 represents an end view, looking in direction of arrow 2, Fig. 2; and Fig. 4 represents a section, on line A B, Fig. 3, of one end of a portion of the machine, as will be hereafter explained.
To enable those skilled in the art to which my invention belongs to make and use the same, I will proceed to describe my invention more indetail.
In the drawings I have represented a stack of four ca1ender-ro1ls,A, B, O, and D, supported in suitable stands E E. The rolls A, B, and D are of chilled iron, or can be made of any other metal which may be preferred for any special use.- Roll 0 is of paper, or of any other desirable material, and is supported by bearin gs e e at each end, attached to the stands E E, as shown in section in Fig.4of the drawings, and the pressure upon this, in connection with the two upper rolls, is produced by screws F F, or by levers, or in any other desirable manner. The bottom roll, D, is the friction-roll and, being connected with roll 0 by gears G G, is run faster than r011 0,and thus produces the desired polish by friction.
The bearings of the friction-roll D rest upon wedge-shaped blocks a a, one at each end. These blocks rest upon stands E at f, and are operated by screws b, which pass through them, and slide them backward and forward, so as to produce the amount of pressure and friction desired; or the same result may be produced by means of levers, or in any other suitable way. H and H are paper-reels.
The paper to be calendered is run from reel H between rolls A and B thence between rolls B and O, thence between roll 0 and friction-roll D, and wound up on paper-reel H. Or, this stack of calender-rolls may be attached to the paper-machine, and the polishing process be accomplished without first bein g reeled.
The spindles b b are provided with wormgears I I, which can be operated, by means of worm-gears J J upon shaft K, when frictionroll D is to be adjusted up or down, to increase or decrease the friction.
Having described my improvement in papercalendering machines, what I claim therein as new and otmy invention, and desire'to secure by Letters Patent, is-
The combination, with a stack of paper-calendering rolls, two or more high, of the friction and polishing roll D, arranged upon s'ep-- forth.
