SPECIFICATION forming part of Letters Patent No. 614,816, dated November 15, 1898. Application filed June 7,1897. Serial No. 639,653- (No model.)
To aZZ whom it may concern.-
Be it known that We, JAMES H. BAKER, GEORGE F. SHEVLIN, and FREDERICK H.
BAKER, citizens of the United States, residing at Saratoga Springs, in the county of Saratoga and State of New York, have invented an Improvement in Paper-Stock Refiners, of which the following is a specification.
Paper-stock is sometimes reground or refined by the action of revolving stones. The present improvement relates to the peculiar construction of'apparatus whereby the stones are more securely held inrposition and adjusted with great accuracy and facility, and as the stones are worn away they can be set up in order to maintain uniformity in the grinding orv refining action.
In the drawings, Figure 1 is a plan view. Fig. 2 is a vertical section longitudinally, and Fig. 3 is an end view with the stationary stone and its supporting-case removed.
The casings A and A are faced to form water-tight joints at 1, and they are connected together by bolts at 2, and the caseais of a size adapted to receive within it the grinding-stones, the stationary stone B being held within the removable head or part A of the case, and the revolving or runner stone B is within a holder 0, that is free to be revolved within the part A of the casing, and the stone B is retained within the holder by sulfur or similar material, and so also is the stone B held within the part A of the casing, and it is advantageous to groove the surfaces of these stones and provide ribs 5 and 6 upon the inner surfaces of the casing A and holder 0, so that the respective stones are attached very firmly in their positions.
The main shaft D is made with a conical portion 3, having a key upon it entering a slot in the hub of the holder 0, and a nut 7, screwed upon the threaded portion of the shaft D, serves to press the conical hub firmly upon the conical portion of the shaft D, so as to hold the parts reliably together and to tighten the same should they become loose, and this shaft D passes through a central hole in the casingA and is supported by a bearing 8- usually being made in one casting, and there is a base F, supporting the frame and the parts therewith connected, and an opening 17 in the lower part of thecasing A communicates laterally into a trough 13 for the discharge of the paper-stock, from which trough a pipe passes in any suitable direction, and the inlet-pipe 12 for the paper-stock is upon the casing A and opens centrally through the bed-stone B.
Upon the shaft D is a centrifugal pump or propeller E, having curved blades and occu pying a recess formed by concaves in the central portions of the stones B B, and this propeller or pump surrounds the nut 7, and there is a feather upon the surface of the tubular nut 7, receiving the propeller, and a screw 11, by which the parts are clamped in position. This allows the propeller to. be set in the proper position in relation to the grinding-stones.
There is a stand or frame G, having a hearing through which the main shaft D passes, and the tie-rod 14: connects the upper end of this bearing-frame to the casing A, and the driving-pulleyHis between the stand or frame G and the bearing 8, and the shaft is of uniform diameter where it passes through the bearings and the pulley-hub, so that an end movement may be given to the shaft, as required from time to time in bringing the surfaces of the stones into the desired proximity one to the other, and in order to insure the proper rotation of the shaft D by the drivingpulley a key 16 is provided on the shaft D and a long groove extends through the hub of the driving-pulley. The tie-rod 14 is screw-threaded at its ends and passes through the stand G and is provided with nuts, so as to be adjustable and support the two-part case and insure the surface of the stationary stone being parallel to the surface of the running-stone when the respective parts are set up in place.
At the ends of the shaft D are steps or pivots at b, and these are adjacent to the hard metal bearings c 01 within the slide-collars e i, which slide-collars rest at their ends upon the level top edges of the respective troughs M and N, which troughs are adapted to receive and hold any oil or lubricating material that may drop, as such lubricating material is applied between the pivots a b and the hardmetal bearings c d, and holes with screws Z are provided in the bottoms of the respective troughs to allow for drawing olf any oil or other lubricating material.
The adjusting-screws K L are in line with the ends of the main shaft D, and there are hand-wheels for moving the respective screws and a lock-whee120 upon the screw L for preventing the same turning after the parts may have been adjusted, and there is a slide-nut n, through which the screw K passes, and a spring 0 intervenes between the slide-nut n and the slide-collar 6, so that this spring tends to press the shaft endwise toward the screw L and to bring the faces of the stones closely together, and the screw L limits the motion and regulates the proximity of the surfaces, and by actuating the screw K the spring 0 may be put under more or less compression and its action regulated, because the same sometimes has to yield for the passage of any obstruction between the stones. A stuffingbox is applied around the shaft D, near the inlet-pipe 12, for preventing the paper-stock leaking out around the shaft at this place.
In operation the paperstock is run in through the pipe 12, and the centrifugal pump or propeller E causes the agitation of the water and paper-stock, and it also produces a pressure for driving the stock through between the moving stone and the stationary stone, and thus refining or reducing the paper-stocl so that it may be properly delivered along with the water, and as the stones may wear down from use the fineness of the pulp may be constantly regulated by the adjusting-screws K and L.
The ends of the slide-collars e i and of the slide-nut n are advantageously made to grip overthe upper edges of the respective troughs M and N, so that they may slide with sufficient freedom and yet be kept properly in line with the axis of the centrifugal paperstock refiner.
In the operation of this machine it is found that the surfaces of thestones wear away to such an extent that the drivingpulley if it was attached;permanently to the shaft would not be in line with the driving-belt and adjustments would frequently be required. By confining the drivin g-pulley between the parts of the frame and allowing the shaft to slide freely through it the stone yields to obstructions, and can also be set up by the screw to compensate wear, and the driving-pulley remains in its proper position.
XVe claim as our invention- 1. In a paper-stock refiner, the combination with the non-revoluble stone and the runnerstone and a revoluble and endwise-movable shaft to which the runner-stone is connected, and two supports for the shaft, of screws acting at the ends of the shaft to regulate the position of the runner-stone to the non-revoluble stone, a spring to allow one stone to separate from the other, a feather and drivingpulley upon the shaft, the pulleyhavingahub occupying the space between the two supports for the shaft, to maintain the drivingpulley in a definite position as the shaft moves endwise through the hub of the pulley, substantially as set forth.
2. In a paper-stock refiner, the combination with the non-revoluble stone and the runnerstone and a revoluble and endwise-movable shaft to which the runner-stone is connected, a frame and two supports for the shaft, of screws acting at the ends of the shaft to regulate the position of the runner-stone to the non-revoluble stone, a spring to allow one stone to separate from the other, a feather and driving-pulley upon the shaft, the pulley having a hub occupying the space between the two supports for the shaft to maintain the driving-pulley in a definite position as the shaft moves endwise through the hub of the pulley, and an adjustable rod between the two portions of the frame, substantially as set forth.
3. In a paper-stock grinder or refiner, the combination with the stationary stone, of a shaft, a holder fitting a tapering portion of the shaft, and a stone secured in such holder, a cylindrical nut screwed upon the shaft and securing the holder upon the tapering portion of such shaft, and a propeller having a hub surrounding the cylindrical nut and secured thereto, substantially as specified.
