Description
WILLIAM J. WEINMAN, or NIOHOLASVILLE. KENTUCKY.
STUFFING-BOX.
Specification of Letters Patent.
' Patented Oct. 27, 1908.
Application filed April 15, 1908. Serial No. 427,169.
To all whom it may concern:
Be it known that I, WILLIAM J. VVEIN- Minna citizen of the United States of America, residing at N icholasville, in the county of Jessamine and State of Kentucky, have invented certain new and useful Improve- 'ments in Stuffing-Boxes, of which the following is a specification, reference being had therein to the accompanying drawing.
This invention relates to a stuffing box particularly designed for pulverizers, and. the primarymbject of my invention is to provide a simple and effective split box applicable to any roller j ourjnal.
A. further object of my invention is to reduce the number of parts of the stuffing box and provide a compact structure that will be strong and durable. To this end, I have devised a stuiling boxfor that type of mill commonly known as the Raymond mill ,-used for grinding and pulverizing various products, such as crude barytes. In connection with what is known in the trade 'as the Raymond mill a stuffing box is bolted to the base of the housing of the journal of the roller, and its function is to prevent grease from flowing into the mill and to prevent grit or foreign matter from coming in contact with the journal and bronze housing thereof.
lonsiderable trouble is experienced in connection with this box due to the construction thereof, the bolts becoming heated and breaking off, causing plates or certain parts of the stufiing box to be precipitated into the mill. As the mill is entirely closed when operating, it is impossible to determine when the box has become disabled-until some damage has been caused thereby.
I obviate the above defects by providing a stuffing box that will be presently described and then specifically pointed out in the appended claims.
Referring to the drawings forming a part of this specification, Figure 1 is a side elevation of my stufiing box as applied to a portion of a pulverizer, Fig. 2 is a side elevation of one of the sections of the stuffing box,
Fig. 3 is a similar view of anadjoining section, Fig. 4 is a plan ofmy improved stuffing box, Fig. 5 is a longitudinal sectional view of the same, and Fig. '6 is a perspective viewof a two-part follower used in connection with the box.
In the accompanying. drawings, I have illustrated a portion of a grinding and pulverizing mill, particularly the housing of the. journal 1 of the roller. The lower end of this journal is provided with a peripheral apertured flange 2, and secured to said flange by bolts and nuts 3 is my splitor sectional stuffing box.
1 Each section comprises a sleeve 4 having ta semi-cylindrical flange 5 at one end and a rcasing 6 at the opposite end. The casing 6 is provided with oppositely disposed lugs 7 and 8,- connected by bolts 10 and nuts 11.
The apertured lug 8 is adapted to receive th stud bolt 10 of the adjoining section and be eld in engagement therewith by a nut 11. When the two sections are secured together by the stud bolts and nuts just mentioned, the flanges 5 .can be secured to the flange 2 by the nuts and bolts 3. In the casing 6 of the stufiing. box is located a two-part wood follower, the parts 12 and 13 of said follower having ship-lap tongues 14, and coil springs 15, these springs bearing against the inner sides of the caslng 6 for retaining the wood followers in engagement with the journal 16 of themill. \The ship-lap connection between the parts of the follower allows the springs 15 to take up the wear of said followers. a
From the foregoing description taken in conection with the drawings, it will be observed that I have devised a stufling box that can be easily removed from the mill without taking out the .rolls thereof. Ap proximately fourparts constitute my stuffing box and these parts are advantageously arranged, whereby it is impossible for the same to become disassembled during the operation of the mill.
I reserve the right to make such changes in the size, proportion and minor details of my invention as are permissible by the appended claims.
Having now described m I claim as'new, is 2-- 1. A stufling box comprising two sections or members each embodying. a semi-cylindrical sleeve terminating at one end in a semi-circular flange and at the other end in a semi-circular casing of'a greater diameger than the sleeve and having an aper-tured lg at each end,bolts connecting said aperturcd lugs, and a two-part follower mounted in y invention what said casing and having ship-lap tongues, and
springs arranged between the ends of said follower andthe inner wall of the casing.
2. The combination with a journal proided on one end with an annular apertured flange and a rotatable shaft extending into said journal, of a stufling box comprising two counterpart sections each embodying a semi-cylindrical sleeve terminating at one end in a semi-circular flange and at the other end in a semi-circular casing, the latter provided with opposite1y-disp0sed lugs,
' means for securing the lugs of said sections 1 together, means for securing the flanged end of said stufling box to the flan ed end of said journal, and a spring-presse two-part foli lower arranged within the casing end of said stufling box to engage said shaft.
In testimony whereof Iafiix my signature 15 in the presence of two witnesses.
