SPECIFICATION forming part of Letters Patent No. 594,696, dated November 30, 1897.
Application filed June 8, 189 7. Serial No. 639,849. (No model.)
`To all whom it may concern.-
Be it known that We, GEORGE R. KING, residing in the city, county, and State of New York, and ALBERT RAYMOND, residing in the city of Chicago, in the county of Cook and State of Illinois, citizens of the United States, have inventeda new and useful Improvement in Roller Pulverizing-Mills, of which the following is a specification.
Our improvement relates to that class of pulverizing-mills which act upon the principle of centrifugal force by means of rollers revolving on the inner surface of rings or dies, the rollers being mounted two on a rollershaft and two or more roller-shafts employed, in order that one shaft and its pair of rollers shall counterbalance another shaft and its pair of rollers, the dies, rollers, and the rollershafts being contained within the walls of When in such mills the operating-shaft passes through the dies and the chamber between the rollershafts, the rollers are necessarily limited in diameter to something less than half the interior diameter of the dies, while rollers of greater diameter are preferable. To render it possible to employ larger rollers was one of the objects of our improvement of such mills for which Letters Patent No. 579,588 were granted to us March 30, 1897; but under this patent it is necessary to employ at least two pairs of rollers and two roller-shafts, as only one pair of rollers and one roller-shaft at the required speed of driving such a mill would make it dangerously impracticable, While the employment of two or more rollershafts and two or more pairs of rollers renders the mill heavier and more expensive than sometimes is required.
The object of our improvement speciiied in this application is to provide a centrifugalroller pulveriZing-inill which has but one pair of rollers andone roller-shaft and the rollers larger in diameter than half the diameter of the dies on which they revolve and so arranged and operated that the tread of the rollers on the dies will have a grinding or slipping action and the two rollers and their shaft will be perfectly self-balanced at all points of their revolution upon the face of the dies, all of which we attain bythe mechanism illustrated by the accompanying drawings, consisting of three sheets, in which- Figure 1 is a longitudinal elevation, and Fig. 2 a plan view of Fig. 1.
Similar designating-numerals refer to similar parts throughout both views.
1 1 represent the bed-plate; 2 2, the legs or standards; 3 3, the driving-shaft, the intermediate portion of which is divided into the form of a quadrangular frame, the sides of the quadrangle (see 3 3, Fig. 2) passing outside of the rollers; Il, the driving-pulley; 5 5, y
the cylindrical portion of the inclosing chamber of the mill, in which is secured and held the two rings or dies; 7 7, the heads of the inclosing chamber, both having central circular openings extending from 8 to 8; 9 9, the rollers; 10, the roller-shaft; 11 11, the rollereshaft bearing-boxes; 12 12, the rollershaft carriers keyed to the driving-shaft and in which are the roller-shaft bearing-boxes, and to which (being part of the same steel casting) are added the inclosing end disks 13 13, which extend from 8 to 8, (in these end disks is a circular opening through which passes the rollershaft;) 15, the opening at the top of the chamber through which the material to be pulverized is fed anddrawn off.
Having pointed out the several parts of our device, we will now explain their functions and the operation of our improvement.
The roller-shaft stands at an angle with the i line of the driving-shaft by placing its bearings on exactly opposite sides of the drivingshaft, whereby the ends of the'roller-shaft move in a circle, and the rollers stand at an angle with the planes of the rings, while the faces or tread of the rollers fall on the hori- Zontal faces of therings which are parallel with the driving-shaft, as shown in Figs. 1 and 2, whereby there is a graduated .variation of the diameter of the rolls, causing a sliding, slipping, or rubbing action on the face of the dies in addition to the crushing action of the rollers, which greatly increases the efficiency of the mill.
We are aware that centrifugal-roller mills have been made of various constructions.l Therefore we do not broadly claim the use of centrifugal rollers irrespective of the manner of arranging and operating them; but
lVhat We do claim as new and useful, and desire to secure by Letters Patent, is-
In a centrifugal-roller pulverizing-mill, a roller-shaft having its bearings on the opposite sides 0f and attached to the driving-shaft and standing at an angle therewith in combination With two rollers having their faces standing at an angle with their own shaft and parallel With the driving-shaft at their points of contact with the faces of circular rings standing at right angles to the driving-shaft, whereby one pair of rollers can be mounted l and rapidly revolved on the same shaft and counterbalance each other, and produce a slipping action between the tread of the roll- I5 ers and the inner faces of the rings, substantially in the manner and for the purposes set forth.
