UNTER@ STATES PATENT IFIQE.
IVM. DIGKINSON, OF WORCESTER, MASSACHUSETTS.
PAPER-ENGINE.
Specification of Letters Patent No. 1,760, dated September 8, 1840.
To all whom t may concern Be it known lthat I, WILLIAM DicKiNsoN, of IVorcester, 1n the county of Worcester yand State of Massachusetts, have invented a new and useful Improvement in Paper- Engines Used in the Manufacture of Paper, of which the following is a description.
To understand my improvement more perfectly however, some knowledge of the engine now in use is essential, and before describing the improvement, I will describe some parts of the engine as now used, the most important of which are, first, an elliptical vat which contains 'the material to be reduced to pulp; second, the roller having steel plates inserted lengthwise in the surface of the cylinder, parallel to each other and vertical to the center, with the edges rising above the surface; third, steel bars fastened to the bottom of the vat under the roller in such a manner that when it revolves the edge of each plate successively passes over the bars and so near thereto as to cut somewhat in the manner of shears, whatever' may be between them. The roller has an axis upon which it revolves, one end of which rests upon a beam or bar called by papermakers a lightener which is fitted so that it may be elevated or depressed by a screw. One end of the roller being thus elevated or depressed while the other end is not materially affected in either way.
This operation therefore necessarily tends to throw the axis out of its bearings, to increase considerably the friction, and as one end of the roller is nearly in contact with the steel bars while the other is raised from them, the friction becomes unequal.
My improvement is designed to correct this imperfection in the engine and to give it greater power and efficiency, by raising and depressing the whole roller and shaft alike and thus making the space between the plates and the steel bars equal from one end of the roller to the other in all stages of t-he work. To accomplish this desirable object I hang the roller, as in the drawing No. one, upon a double lightener, No. two, so that it revolves between beams or bars with its axis resting upon each. At one end these bars or beams or lighteners are united as in my drawing by a strong round bar of iron No. three, which passes through them and also through two upright supporters rising a little above the top of the vat,
-which supporters are firmly xed to sustain the work and thus when the other end of the double lightener is raised or lowered this end coupled with the round bar llo. three works upon it in the manner of a hinge. The other end is united by a broad flat bar of iron No. four, with the ends turned down at right angles toward the bottom of the vat, the lighteners are bolted to this a little below the angle. This bar rests also upon supporters No. live much like those at the other end, the ends of this bar thus turned down may extend a little below the lighteners as in No. six and serve to keep them firm when raised or depressed. The lighteners should be bolted on the outside of this broad bar, and not to the inner side as in the drawing. The double lightener being thus prepared rests in a nearly horizontal position with the upper part nearly on a level with the surface of the water in the vat No. nine. The roller being inserted as in No. one is according to my drawing to receive its motion from a band applied to a pulley No. eight, and is raised or lowered at pleasure by a screw, or by screws as in llo. seven, inserted in the flat connecting bar of the double lightener which bear against the boards 5 as appears by the drawing. This screw, or these screws necessarily carry up or down the whole double lightener No. two, and with it the whole roller and shaft No. one, while that in the engine now in use elevates and depresses but one end. The engines in use as far as I have seen or known have a long, heavy, clumsy axis or shaft to the roller connecting it with the moving power usually by a gear.
In my improvement which admits the easyl application of a band I am able to dispense with a large portion of this axis or shaft, and by an improvement in the vat No. nine constructing therein a hollow midfellow as it is called of suiificient length and width (as in No. ten,) to receive the inner bar or beam of the double lightener (and the band and pulley to drive the machine if desired) I am able to raise the roller and shaft entirelyout of the vat No. nine, This vat No. ten or what I call the hollow midfellow is a vat within the vat No. nine, as represented in the'model and drawing around which when the roller is in motion, the water carrying with it the material to be ground flows, and from which the water is wholly excluded-by this arrangement the improved engine is more easily repaired than any now in use. It may be conveniently placed in almost any part of the mill With less regard to the moving power than is nowlnecessary, as the belt may be carried to it with very little trouble in whatever part of the mill it may be. Is less eXpensive-more likely to keep itself in repair than any enginesrnow used in the manuj facture of paper, and when repairs are necessary it is much more easy to make them, as the whole engine can be easily seen by raising the double lightener, and thus the roller. It combines many other advantages which it'may not be necessary to mention.
That I claim therefore as my invention is*- The act of raising and lowering at pleashereunto subscribed.
WM. DICKINSON.
