PAPER-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 492,209, dated February 21, 1893. Application filed March 12, 1892. Serial No. 424,676. (No model.) Patented in Canada April 27, 1892, No. 38,815.

To all whom it may concern.:

Be it known that I, AMAsA NATHANIEL KIDDER,of Chelmsford, in the county of MiddleseX and State of Massachusetts, have invented certain new and useful Improvements in Paper-Makin g Machines, (for which I have obtained Letters Patent in Canada, dated April 27, 1892, No. 38,Sl5,) of which the following is a specification.

1o My invention has relation to the art of making paper on cylinder machines, so called, in which wood, jute, linen and cotton fiber held in suspension in water and forming what is known as pulp, flows into a vat in which rer 5 volves a cylinder covered with fine wire cloth or netting. The cylinder is hollow and is provided with a hollow shaft or opening about the shaft, out of which flows the water drained from the pulp proper, which latter from the zo pressure of the water within the tank is collected upon the wire cloth of the cylinder and is taken off on a felt, and when pressed and dried forms the paper. In consequence of the motion of the cylinder and the current of the z 5 water which runs in aline parallel to the motion of the cylinder, the fibers tend to lay themselves upon the cylinder in the same direction which in the manufactured paper is longitudinal of the sheet, so that the paper is 3o strong and not easily torn when tension is brought thereon across the fibers, but weak and easily torn in the direction of its length and in line with the direction of the fibers. Itis very desirable that the fibers should be 5 5 made to form on the wire cloth of the cylinder in all directions, so that the same may be, in a sense, felted or intertwined in order that the paper may be rendered equally strong in all directions. l have discovered that if 4o the pulp in the vat is agitated `in close proximity to the cylinder on a line at a right angle to the motion of the same, the objections mentioned may be overcome and the desired end obtained. Y

My invention consists in the construction and combination of parts as hereinafter fully described and claimed.

In the drawings formings partof this specification: Figure 1, is a top plan view of my 5o improved machine. Fig. 2, is a transverse sectional View thereof taken on the line 22,

of Fig. 1. Fig. 3, is a horizontal section taken on the line BL-3, Fig. 2. Fig. 4, is a detail end view. Fig. 5, is a sectional view taken on the line 5 5, Fig. 4. Fig. 6, is a diagram show- 55 ing the results attendant upon the employment of my improved means.

The same letters designate the same parts in all the figures.

ln the said drawings: a designates a vat or 6o tank, which may be of concaved or other suitable form, in which is arranged a hollow cylinder b covered with wire gauze or fine wire cloth. The journals of the cylinder are arranged in suitable bearings in the sides of the vat, so that the cylinder may be rotated, and the shaft c of the latter is made hollow with an opening at 011e end, as at cl, numerous holes e being formed in the shaft, affording means of communication between the in- 7o terior of the cylinder and the hollow of the shaft, or other suitable means may be provided, so that the water in the cylinder may iiow out and be drained from the fiber collected upon the cylinder. Any desired means `7 5 may be provided for rotating the cylinder at the necessary speed.

Arranged on a plane at or near the top of the cylinder is a rectangular frame consisting of the side rods f f and the removable con- 8o necting end bars g g.` The rods f are mounted in sleeves or bushings 7L held in boxes t', so that the said rods may be reciprocated in their bearings.

j designates a series of blades, which are supported at their ends by the rods f and eX- tend around or partially around the cylinder in the direction of its movement. The outer edges of the blades j are provided with iianges 7o which serve to strengthen the same and 9c also to perform a function to be presently mentioned. The series of blades are divided cena trally below the cylinder on a line coincident with the axis of the latter, and hingedly connected, as at Z, so that the free ends of the blades may be separated to admit of the cylinder being passed therebetween, and be again adjusted in piace.

One way in which the cylinder may be re= moved is by removing the caps of the bearroo ings of one of the rods f, andthe shaft of the cylinder; which latter may then be lifted out of the vat.

m designates a stud connected with one of the cross-bars g, Which extends down into a cam groove, n formed in ,the periphery of a cylinder or pulley 0, connected with which is a pulley p or other suitable means whereby l the pulley o may be rotated, in order that, through the medium of the cam groove,` stud fm, and rectangular frame, the blades j and their connected flanges la may be vibrated or reciprocated. Strengthening strips or bars g. may be connected With the iianges 7c or outer edges of the blades inl order tostiften and strengthenthe structure connected with the rectangular frame.`

In the: practiceof mfy'invention the. pulp will flowintothe vat, tliefc-ylinder will be rcvolved. in the usual or any Suitable Way, and thercctangn-lar frame will b e reciprocated by the means explained so, as tovibrateorrecip.- rocate the blades, and their attached iianges. k on a line-su-,bstantiallyat a right angletothc motion of the cylinder and in theidfirection of its axis. By thisgoperation the iberswhich, as` before. stated tend. to take the line of the currenty and* lay' themselves iipon the1 cylinder in adirection parallel. to its linel of motion, j

will beactcd upon thei blades. j and their ianges; 7a, to intertwndv them and laythexn upon thewifre fabricornetting in; all: directions asis olea-rl yshown in-Figl. Theblades. j, being of thin metal, with their i'niner edges` in proximity with the cylinder; and; having theVA anges la, form improved agiitat'ingf devices: for the pulpow,ing to the irreglilarsn-rfaces or angles presented during ltheir mover ment as described.,

By my invention-,the1 strengthl ofthe paper manufactured beingr equal in all directions,

the paper-can bev made thinner Without liability of breaking down`and occasioningthe expensel of broken Waste, than Where,

the fibers are substantially all laid in parallel With the direction of the. length of the sheet, so as. to render the same comparatively Weak in that direction. In short, by my described process I am enabled to enhance the value of the product and at the same time reduce the Weight or thickness of the paper, and conse.-

qucntly lessen the cost of its production.

Having thusdescribed the nature of my invention and explained away of constructing E and using the sam-e, though without attempting to set forth all of the forms in which it Y may be made or all of the modes of its employment, I declare that, what I claim is- 1. A machine for making paper, comprising i in its construction a cylinder, a vibratory frame or su pport, and iiat agitating blades eX- tending in a line parallel with the mov-einen t.

i of thecylinder connected with said frame, and i located in proximity with they cylinder-asdescribed.

2. A machine fo|-,-making paper, comprising sin its. construction a cylinder, a vibratorry i frame or support, and aseries of agitatingdevices divided centrally on a line, parallel with a the axis of the cylinder and hin-.ged together', I the agitating deviceV being connected to the i said frame and arranged in proximity to the,

cylinder, as described.`

3., A inachineter makingpaper, comprising :in its construction a cylinder,` a` vibratory i frame or support, and agitatingdevices. con.- n-ected with said. frame and located in proxi imity with the. cylinder, the said agi-tatin g diei vices; having the form oli thin, fiat blades ex'- L tending in a line parallel with th-e motion ot i thecylinder,and provided on their outeredges i with. fianges, as described.

In testimony whereof If have signedmty name to this specica-tion, in the, presencefo'l ftWo subscribing Witnesses, this. 5th day oii March, A. D.. 11892;.
