' mEa-cRossE SPECIFICATION forming part of Letters Patent N 0. 698,304, datedApril 22, 1902. Application filed September 26,1901. Serial No.7fil656. (No model.) d d T at whom'it may concern:

Be it known that-I, PHILIP 'MICKLE, acitizen of the United States, and ajresidentof Troy, in the county of Rensselaer and State of New York, have invented a new and Improved Fiber-Grosser, of which the following is a full, clear, and exact description.

The invention relates to machines for making paper from all kinds of fiber, especially rope and wood; and its object is to provide a new and improved fiber-crosserfor use in the cylinder-vat and arranged to insure a perfect crossing of the fibers in the pulp to cross the fibers in all directions, and thereby insure the formation of a very strong and durable paper. I

The invention consists .of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention' rable paper, it is essential that the pulp fibers be crossed and interlocked with each other as muchas possible. With the device presentlyto be described in detail the stock is thoroughly agitated in such a manner that the fibers are crossed immediately previous to passing onto the cylinder and to the vat, so as to hold the fiber in the crossed and interlocked position during the formation of the stock into paper.

' A vat A of usual construction is provided at one end with an inlet-pipe B for discharging the stock into the receiving-chamber C, arranged in the vat and having at its top an outlet 0, leading to the feed-chamber D, containing the cross-bar D, having its lower end scalloped for gaging the stock passing from the chamber D into the vat A proper. The stock'th'uspassing into the vat comes in contact with the wheel E, mounted to rotate in the direction of the arrow a in front of the cylinder F, spaced from the apron G, ex-

able hearings in thesid'es' of thejvat A, and

.on' the outer end of the said shaft is secured a pulley E driven by suitable means so as to rotate the Wheel E inthedirection of the arrow at and at a speed considerablyexceeding that'ofthe cylinder F, which rotates in the di-v rection of the arrow b. The wheelE is provided with radial wings E preferably three in number anddiminishing in height from the middle of the wings to the ends thereof, as plainly indicated in Fig. 2, so that when the wheel E rotates the wings E? agitate the stock to throw the same from the middle of the vat toward the end ther'eof,whereby the fibers are caused to cross each other and interlock pre vious to passing to the cylinder F. It is understood that when the pulp passesunde'r the peripheral surfaceof the cylinder F and the fibers are well crossed and interlocked they remain in this position during the rest of the process in paper-|naking--that is, while on the web H and while passing through the various rolls. Thus by the arrangement de scribed the fibers are thoroughly crossed and interlocked to insure the formation of very 'durable and strong paper.

Havin g thus d'es'crihedfmy invention, I

claim as new and desire to secure by Letters "Pate'nt 1. Apaper-inaking machine,hav'ingawheel mounted to turn in the cylinder-vatand arranged to cross the fibers in the pulp previous to the latter passing to the cylinder; the said wheel having wings gradually decreasing in height from the middle of the Wings to the ends thereof, as set forth.

2. Inapaper-makingmachine,thecombination of a vat having a feed-inlet, a cylinder, and a fiber-crossi n g wheel revolubly mounted in said vat between the cylinder and the feedinlet, said Wheel provided*=w-ithlongitudinally-tapering blades which are arranged to the vat. 1 I I I 3. A paper-making machine, provi'ded'with a cylinder-vat and a wheel extending transversely in the vat and mounted to rotate at a higher rate of speed than the cylinder, the

throw pulp fibers in crossing paths, within wheel being located between the cylinder and the inlet, and the wheel having radial wings diminishing in height from the middle of the wings toward the ends thereof, as set forth.

4. In a paper-making machine, the combination with a vat, and a cylinder, of a fibercrossing wheel mounted within said vat and revoluble in an opposite direction to, and at greater peripheral speed than said cylinder, 1

said wheel having longitudina1ly-tapered Io blades arranged to direct pulp fibers in crossing paths in the vat.

In testimony whereof I have signed my name in the presence of two witnesses.
