l SPECIFICATION forming part of Letters Patent No. 706,985, dated August 12, 1902. i Application led June 6, 1902. Serial yNo. 110,523, (No model.) 4
.To all whom it may concer/z.'
Be it known that I, FRANK P. MILLER, a citizen of the United States, and a resident of Downingtown, Pennsylvania, have invented `certain Improvements in Beating-Engines, of
which the following is a specification.`
The object of my invention is to so construct a beating-en gine that paper-stock can be properly reduced land the ground stock separated from the material in circulation without interrupting the iiow of the said ma` terial, so that the finished stock can be carried from the machine andnew stock added, making the process of reducing the paper in the beating-engine continuous.
In the accompanyingdrawings, Figure l is a longitudinal sectional 'View of my improved beating-engine. Fig. 2 is a plan view of one end of the engine. Fig. 3 is a sectional view on the line 3 3, Fig. 2; and Fig. 4 is an enlarged sectional view on the line 4 4, Fig. 2.
A is a vat separated by the usual midfeather a, forming two channels through which the paper-pulp is traversed. In one of these channels is the beating-roll B, mounted on a shaft B', carried by suitable bearings, and having knives or blades ZJ.
C C are the knives, mounted in the frame ofthe machine, between which and the beating-roll the pulp is passed.
A' is the backfall, over which the pulp is carried by the beating-roll B, and directly back of the backfall is a screen D. (Shown clearly in Figs. 3 and 4.) This screen is suspended from a shake-frame D', which can be constructed in any suitable manner, and any means may be provided for shaking the frame so as to agitate the screen. The screen in the present instance consists of a frame ql, in whichare assembled a number of plates d', each plate being recessed at each side, so that when the plates are assembled they form narrow slots for the passage of the pulp, as shown inFig. ,'lhis'screen may be perforated with circular holes or slots of any shape, and the slots may be formed in any manner without departing from the main feature of my invention. The perforations are of such size as to allow the finished product of the machine to readily pass through the screen into the chest E, which is directly under the screen and from which the product is withdrawn either by gravity or by means of a pump through the outlet-passage e. Beyond the screen D is a continuation A2015 the backfall A. The untinished product passes over the screen and over the backfall and circu lates through the channels, to be acted upon again by the beating-rol1. In the present instance the screen D isarranged on an incline Lfrom the backfall A', so that the unfinished material will more readily pass over it; but
`it will be understood that it may be horizontal or atanyincline desired,dependinggreatly upon the material being treated.
-are so arranged and shaped that the ordinary stock will pass between them,while the strings and similar material will be caught by the forks, and when these strings accumulate the operator simply turns the shaft F and raises the forks and removes the strings, which can either be collected for other paper-stock or reduced in the machine.
The shaft F in the present instance is suspended from the shaftF by arms f', and this shaft is operated by a leverf2, so that the shaft F and its forks can bemoved out of the Way when desired.
While any suitable means may be provided to shake the screen D, in the present instance I have shown one form of shaking means which I will now proceed to describe. Mounted on pedestals K K on each side of the vat are spring members 7c, from which is suspended by bars 7c the screen D. I is a driven shaft having cams t' thereon, which act against plates c", carried by the spring members 7c k. The shaft I is mounted in suitable bearings and may be driven from the beater-shaft B, if desired, or may be independentlydriven.
I have shown in Fig. 4 a yielding lip a' on the backfall A', which will overlap the frame of the screen D, so as to prevent the material from entering the chest E except through the screen. A like lip a2 may be provided at the opposite end of the screen, which will overlap the portion A2 of the backl'all.

screen, and there is sufficient suction caused by the agitation ofthe screen to draw certain particles of the material through the screen.
These particles are those that have been reduced to the desired condition, and they pass into the chamber E under the screen and are drawn out through the pipe, which is connected to any suction device, either gravity or pump, as desired. The balance of the stock circulates through the vat, passing under the roll until it is finally reduced to the desired condition, when it will pass through the screen into the chamber E.
It will be seen that whenmy improved machine is once set in motion the processiscontinuous, and new stock can be added without stopping the mechanism. In fact after the machine is once charged with paper-stockthe finished stock can be removed and additional stock added from ytime to time.
The rags, strings, and similar material can be collected by the forks f, While wires, nails, and other heavy foreign matter will collect in the bottom of the vat and in the pocket m, which is provided for this purpose.
My improved beating-engine is especially` adapted for grinding and reducing old paper and paper-stock; but it will be understood that it may be used in connection with any vmaterial which can be ground to a pulp to form paper.
' In reducing some classes of paper-stock it has been the practice towork the beatingengine until all the stock is reduced to such a consistency that it can be transferred toa paper-making machine. It has been found in reducing the paper-stock in this manner that a great portion of the material was reduced to such an extent that the ber was destroyed, and consequently the paper which was made from the pulp was not strong. This is entirely obviated by my improved machine, and the pulp as soon as it is in condition to be removed from the machine passes through the screen and away from the pulping mechanism. The machine can be either used as a continuous machine or as an intermittentlyoperating machine, according to the desire of the operator. y
. The process of reducing paper-stock consisting in passing the stock through a beatingengine and separating the ground stock from the materialin circulation without interrupting the flow of the said material is set forth and claimed in a separate application for patent filed by me on the 13th day of March, 1902,-Serial No. 98,011.
The material is reduced by 4 iroaess .I claim as my invention*- l. The combination in abeating-engine, of a beating-roll, a screen back of the beatingroll, and achest under the screen, substantially as described.
2. The combination in a beating-engine, of a vat, a beating-roll, abackfall, a screen at the rear of the backfall, and a chest under the screen sothat the material will pass over the screen and the finished product will pass through the perforations of the screen and into the chest, substantially as described.
