PATENT VIETTS L. RICE, OF NEIV YORK, N. Y.
PULVERlZlNG-MILL.
SPECIFICATION forming part of Letters Patent No. 469,334, dated February 23, 1892. Application filed June 6 1891. Sen'al N0. 395 ,396. (N0 model.)
To aZZ whom it may concern.-
Be it known that I, VIETTs L. RICE, of New York, in the county and State of New York, have invented a certain new and useful Improvement in Pulverizing-Mills, of which the following is a specification.
I will describe a mill embodying my improvement and then point out the novel features in the claims.
In the accompanying drawings, Figure 1 is a central vertical section of a pulverizing-mill embodying my improvement. Fig. 2 is a horizontal section taken at the plane of the dotted line 00 ac, Fig. l,with certain parts which are below that plane broken away, so as to exhibit parts which would otherwise be concealed. Fig. 3 is a horizontal section taken at the plane of the dotted line y y, Fig. 1. Fig. lis a horizontal section taken at the plane of the dotted line .2 .2, Fig. 1. Fig. 5 isaside view of the upper portion of a mill embodying my improvement.
Similar letters of reference designate corresponding parts in all the figures.
A designates a chamber into which material to be pulverized is introduced. It is of cylindric form and, as here shown, has in the side of its upper portion afacing ringor lining A. This is shown as supported upon a shoulder formed in the chamber.
The chamber A may be supported in any suitable manner as, for instance, by being bolted to beams B or seated upon masonry. Outside the chamber a ring A is arranged, and this may be cast with the chamber. It is considerably larger than the exterior of the chamber, and hence an annular space is left between it and the chamber. This space is traversed by radial projections or bridges a, whereby the chamber and the ring are conconnected. As here shown, flanges extend from the ring A and rest upon the beams B or masonry.
The chamber A is surmounted by a screen 0, here shown as made of reticulated material and tapered upwardly. It is open at the top and bottom. Outside the screen 0 a shell D is arranged. Itis considerably larger than the screen, so that an annular space is left between it and the screen. The ring A aflevel with the top of the screen the shell D extends inwardly, so as to form a seat forthe upper part of the screen. Itis extended above the screen and tapered upwardly. At its upper extremity it is extended inward, but its top is provided with a central hole a of considerable size.
Below the chamber A is arranged a hopper E, which may be secured to the beams or masonry, andpreferably tapers downwardly to a central opening 6. A conveyer F may be fitted in this opening c. Material maybe introduced to the chamber A through an inclined chute G, extending through the shell D, and also through the screen 0 above the chamber. Material to be pulverized will be introduced into the chamber A, and when sufficiently pulverized will be discharged through the screen G into the shell D, and will flow thence through the space between the chamber A and its ring A into the hopper E. It may be conveyed from the hopper by the conveyor F to any suitable point.
I have shown a single roll H, combined with the chamber A and constructed so as to revolve around the same in contact with or in close proximity to the facing ring or lining A. This roll is mounted upon a shaft H and is suspended from a shaft 1. As the roll revolves around the chamber, it is intended to rotate upon its own axis. There is also an inclined flange or blade J used. This is intended to rotate with the roll and will aid in the pulverizing besides elevating and discharging the pulverized material through the screen (1.
Before explaining the details of the roll H and the flange or blade J, I will explain the manner in which the shaft I is supported and driven.
K designates a platform or table supported by three legs is k 70 .It is provided with a central hub k, in which isa cylindric bearing fitted with a lining-piece 70 which is externally cylindric, but internally flares upwardly. This lining-piece snuglyfits the bearing in the hub 70. It has a number of circumferential grooves formed in its exterior, with which engage teeth formed upon the end of alever k which is fulcrumed to the table or platform K by a pin it. By means of this lever acting in conjunction with the grooves of the liningpiece, the latter may be elevated at any time to compensate for Wear, and it will not. interfere with the turning of the lining-piece.
The shaft I has a portion which is tapered downwardly on its exterior and which fits snugly within the liningpiece It. It also has a flange t' that extends over the top of the hub It. Intermediate of this flange and the hub 7s washers z" of any suitable material may be used. The weight of the shaft I and its appurtenances is sustained by the coaction of its flange 1' with the hub is.
It will be seen that the shaft Iishollow and that it is open at the top but closed at the bottom. Owing to this it may be filled with oil. A lateral hole or a number of such holes in the shaft I at a level with the washers z" affords provision for the discharge of oil from the shaft to lubricate these washers as well as the top face of the hub le -and the under side of the flange 2'. To provide for lubricating this joint after oil shall have descended below the lateral opening or openings just mentioned, I preferably extend from at least one such opening downwardly into the shaft a wire 2' covered with any braided or woven covering or any other absorbent material through which the oil may ascend by capillary action.
Rotary motion may be imparted to the shaft I in any suitable manner-as, for instance, by means of a belt-pulley I, affixed to its upper end.
The shaft H of the roll H is carried by the shaft I and suspended from the latter, there being formed between it a trunnion-joint L, which permits of the swinging of the shaft H outwardly. This joint does not allow the shaft H to rotate; but as the shaft I rotates the shaft 11 is carried with it and caused to revolve around the chamber A. Centrifugal force generated during this motion carries the shaft H outwardly, so as to give the roll II a tendency to travel around the facing ring or lining of the chamber A. The trunnion-joint L may be lubricated by oil flowing from the interior of the shaft I. AsI have fully illustrated and described the details of this trunnion-joint L, including the manner of lubrieating it, in my patent, No. 445,821, granted February 13, 1891, I deem it unnecessary to give further details as to this feature of the present mill.
Just above the roll H the shaft H is provided with a flange h. Against this the top of the roll may bear. Above it is fitted a collar M, having a recess on the under side to fit the flange h. Anumber of screws pass through the collar M and enter and engage with tapped holes formed in the upper part of the roll II. By this means the roll is supported upon the shaft H',while beingleft free to rotate with the collar M around said shaft. The shaft, as here shown, is reduced in size below the flange 7t and is extendedinto ahole formed in the center of the roll. The roll has formed in it a cavity h, which is closed on the under side by a removable screw-plug h of hollow construction. By this meansI provide in the bottom of the roll a sediment-chamber and one which may be opened at pleasure to remove sediment. As here shown, the flange or inclined blade J has fastened to it a sleeve N, which surrounds the shaft H and is made fast to the collar M. It may be formed integral with the collar M. This sleeve N is somewhat larger than the shaft H, so that an annular space is formed between it and said shaft. At its upper end is a collar 42, that extends inward into contact with the shaft H, so as to serve as a cover to close the space between the shell and the shaft I-l. Oil may be introduced into theshell N by simply sliding the collar 12 upward along the shaft H to expose the upper end of the shell. A jam screw extending through a tapped hole in the collar n may be turned to impinge against the shaft H to hold the collar in position to close the opening between the shaft and sleeve.
The sleeve N forms an oil-reservoir, whereby the joint between the roll and the shaft H will be lubricated. It will also protect this joint from the pulverized material. By means of the chamber formed at the lower end of the roll by the cavity h,in conj unction with the hollow plug 7L2, a plentiful supply of oil for the lubrication of the lower part of the shaft is maintained and the oil prevented from escaping to the material being treated in the mil While I have only shown my improvement applied to a mill having a single roll, I am unwilling to limit it to such a mill, as it can be applied to a mill having a number of shafts H and rolls I-I.
Vthat I claim as my invention, and desire to secure by Letters Patent, is-
1. In a pulverizing-mill, the combination, with a chamber for material to be treated, a roll traveling around the same, and a shaft whereby said roll is carried and upon which it is capable of rotating, of a collar fastened to said roll and a flange extending from said shaft between said collar and roll, substantially as specified.
