ATTACHMENT FOR CALENDER-ROLLS FIOR PAPER.
SPECIFICATION forming part of Letters Patent No. 268,809, dated December 1.2, 1882, Application filed October 23, 1882. (N0 model.)
To all whom it may concern.-
Be it known that we, JOHN E. LARKIN, of
Poquonock, in the county of Hartford and State of Connecticut, and JARVIS E. TOWER,
of Rainbow, in said county and State, have in-- vented certain new and useful Improvements in an Attachment for Calender-Rolls for Paper, of which the following is a description,
reference being bad to theaccompanying drawings, where- Figure l is a front view of our device attached to a stack of three rolls. Fig. 2 is a side view of the same. Fig. 3 is a detail sectional view of the adjusting device, in which the buffer-roll is journaled. Fig. 4 is a detail view ofcam-slot in buifer-roll journal.
()ur invention relates to devices used for forming a smooth, even surface on the paperrolls usedin calenders; and it consists in a buffer-roll having a roughened or cutting surface,
and so arranged upon the frame of the stack of rolls as to resurface the paper-roll without removing it from the stack. i
In the accompanying drawings, the letter a denotes the frame of calender having a stack of three rolls and made in the usual manner, the rolls b and (I being of iron and c of paper. Projecting stands 0 are cast integral with or secured to the frame a, and have inclined mortises fin their upper surface, the bottom of the mortise bearing the adjustable pillow-block g dovetailed to it, as shown in Fig. 4. The
blocks g are reciprocated on their beds by screws h, pivotally connected to each, and are guided by pins g entering suitable openings in the frame or stand. A lock-nut, it, serves to hold rod 71, which turns in a threaded hole in the stand in any desired part of its path. In these pillow-blocks are journaled the shaft i, which bears the buffer-roll It, having a suitable cutting-surface-as emery, or the like-adapted to cut and smooth the surface of the paperroll 0. Near one end the shaft 11 has a peripheral cam-slot, i, into which takes the screwpin 1, by means of which the butter-roll is given an endwise play or vibration as it revolves. A
' paper-reel, m, is fixed to the floor in a suitable position in front of the stack, and is turned by belts from a pulley on the stack-rolls. From I the pulley on this reel a belt connects with pulley 1', fast to shaft 6.
When the calender is in ordinary use the buffer-roll is withdrawn from contact with the roll 0 by means of the devices described; but when the paper-roll is to be resurfaced the buffer-roll is placedin contact with it and held there, and by means of connecting-belts and pulleys rapidly revolved against it, thoroughly grinding and smoothing its surface as it revolves, the endwiseplay greatly aiding in the operation. As soon as a proper surface is regained the buffer-roll is retracted, and the usual Work of the calender resumed with but little interruption.
Prior to our invention it has been the custom to remove these paper-rolls when their surface has become dented and imperfect, and regrind them or cut them true in a lathe at a loss of time and labor. ()ur device saves most of this, as the paper-rolls are reout in place in the stack. The inclined position of the pillow-blocks and their bed in relation to the fixed dri.ving-pulley(in this instance on the reel) enables us to move the buffer-roll to and from V the paper-roll without altering the tension of the belt.
We claim as our improvement 1. In combination,in acalender,a paper-roll, c, and an adjustable vibrating buffer-roll having a grinding-surface, and actuating mechanism, all substantially as' described.
2. Inacalender, alaterally-adjustable buii'erroll and operating mechanism, whereby a paper-roll may be resurfaced in place in the stack, all substantially as described.
3. In a calender, a stand or bearing for a buffer-rolhhaving an inclined bed in which the pillow-block is dovetailed and reciprocated, all substantially as described.
4. In a calender, in combination, buffer-roll It, stands (2, having mortised bed and a guidesocket, pillow-blocks g, having guides g", and screw-rod h, all substantially as described.
