UNITED STATES PATENT OFFICE,
LORENZO DEAN, OF FORT EDWARD, NEW YORK.
IMPROVEMENT IN ATTACHMENTS T0 PAPER-MACHINES TO PREVENT THE STRAINING AND BREAKING 0F i THE PAPER DURING MANUFACTURE.
Specification forming part of Letters Patent No. 166,134, dated August 9, 1870.
To all whom 1lb may Iconcern.-
Beit known that I, L'oRE'Nzo DEAN, of Fort Edward, in the county of Washington and State of New York, have invented a new and Improved `Attachment for'lreventing the- `is a detached view of a variety of Fig. 2.
This invention has for its object to prevent the straining and breakage of the paper sheet at any point during its passage through the machinepriorto its reaching and passing between the calender-rolls, having especial reference to the prevention of breakage while the sheet is passing from the dryingto the calender rolls. V
The invention 1 lconsists in sliding ,boxes placed in vertical or inclined standards or the equivalents, and supported upon springs, in which boxes the journals of the carryingroll, over which the sheet passes on its way from the drying roll to the calenders, are mounted, the springs enabling the boxes and the carrying-roll to yield to the strain exerted upon the same by the sheet, and thus prevent the rupture of the latter;
`In the drawings, a is one of the standards in which the calender-rolls b are mounted. c is one of the inclined standards in which the carrying-roll d is mounted. e isa longitudinal recess in the top of the standard e.. f is a box placed in the recess e, and provided with a stem, h, which projectsidownward into an orifice, t, in the standard, below the recess e. k is a spiral spring,that surrounds the stem h, rests upon the bottom of the recess e, and supports the boxf. Z is a rivet that connects the two branches ofthc standard c, and prevents the box f from rising, owing. to the operation of the spri ugs k, toohigh in the recesses e. m is the drying-roll; n, the paper sheet.
In passing throughthe machine the sheet is liable to befstrained while in its moist and slightly-coherentcondition, -especially in cylinder-maehines,where the grain runs but one way, and these weakened portions of the sheet are liable to suddenly give way under the tension at any point between the carryingroll and the calenders,where it is-subject to a steady and uniform pressure. If the yielding boxes, supporteduporrsprings, as'herein described, be -freely distributed throughout the machine at -allpointswvhere there are rollers over Vwhich the sheet passes,they prevent in a great measure all, suchl straining and breaking. The sidesofv therecess e are made concave, and the sidesof the boxesf correspondingly convex, as shown in Eig. 3, in order to prevent the latter from slipping outof the standards. l
I do not limit myself to the manner of combining the box and spring herein described, as other equivalent modesmay be adopted. VIn Fig. 4, for instance, the springs are attached at one end to any part of the frame, and bent upward and backward over the tops of the same to reach the rolls, and the boxes formed on the springs, and the roll mounted in the boxes. This is a convenient arrangement where standards cannot be used and the strain on the paper is light.
Having thus described my invention, what I claim as new, and desire to`secure by Letters Patent, 'is- The standard c or other part of the frame, in'combination with the box f and spring k, substantially as described.
