Specification of Letters Patent.
Patented July 17, 1906.
Application filed August 14, 1905. Serial No. 274,208.
To all whom it may concern: 7
Be it known that I, Gnonon LEWIS PRATT, a citizen of the-United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented certain new and use-.
'ful lmprovements in Means for Lubricating Pulverizing-Mills; and I do, hereby declare provide a thoroughly efficient and satisfactory means for lubricating certain parts of a machine, such as, say, a pulverizing-mill,
which are necessarily in the operation of the machine subjected to intense friction and consequent liability to wear; By my improved antifriction means or means adapted thoroughly to effect lubrication of these parts the durability and strength of the machine as an entirety are greatly lengthened and en hanced and the noise and wear incident to the machines are I largely lessened.
With this object in view the invention consists in the novel construction, combination, and arrangement of parts, as hereinafter set forth in the specification, summed up in the claims, and illustrated in the drawings.
It being understood that my improved antifriction means may be employed in any position in any machine where such use may.
obviously be efficacious I have shown, merely for sake of illustration in the drawings, my
invention applied to a pulverizing-machine and only such parts of such machine as are necessary for a comprehension of the applicationv thereto of my invention.
Referring to the drawings, Figure lis a fragmentary central vertical section of a movable roller-carrying table," of one roller and its supporting-shaft, and of a pan adapted for the reception of the material to be pulverized and within which the roller works, my antifriction means being disclosed as applied to such shaft and its supported roller. Fig. 2 is a detail view of a bearing-disk, thrust-plate, or lubricant-distributing member located at the bottom of the shaft. Fig.
3 is a bottom plan view of a shaft which may be provided with transverse grooves or channels therein, as shown. Fig. 4 is a fragmentary vertical section of an 'alternate'construction.- Fig. 5 is a section on line a; as, Fig. 4; and Fig. 6 is a sectionon line B B, Fig. 4.
Referringtothe drawings, A designates a driving-shaft operated in any suitable manner and carrying a roller-supporting table B, to which may be hinged or pivoted a head C, having an internal-threaded opening c. Remo'vably secured in the openin c is a depending shaft D, the upper end 0 which may be threaded, as shown at d, for this purpose and the lower end desirably enlarged,.as at (P, which enlarged head is slightly smaller in transverse cross-section than the chamber in which it rests, as shown in the drawings, for a purpose hereinafter appearing. Carried by shaft D at its lower end and' prevented from accidental removal therefrom by the enlarged head d is a roller E, desirably having a neck portion e, which may be threaded at its upper end, as at e A bushing F,provided with longitudinal grooves is adjacent the shaft D, (for a purpose hereinafter appearing,) may be placed intermediate roller E and shaft D, and the bushing may be threaded at its upper end, as at f, engaging the threads e of a lock-nut e Screwed on the bushing F at its upper end may be a bushing-cap, gland, or followerG, provided with internal threads 9 for this purpose but any other suitable means may be employed to prevent escape of lubricant at this point. A bottom plate H may be removably secured in any suitable manner to the under side of roller E, as by bolts h and nuts 7%.
Although not indispensable, I prefer to utilize what I call a lubricant-distributing member or bearing-plate, shaped, preferably, in the form of a circular disk I, which is supported in contact with the under periphery of head (i of shaft D and the upper face of plate H, as shown. This disk may be provided with radial grooves or the like i on either surface thereof in contact with the under face'of the head (1 or the upper surface of plate H, it being understood that instead of these radial grooves in the disk I, I may provide radial grooves or the like in the underface of the head (1 of shaft D, as shown at i Fig. 3.
Internally of shaft D is a longitudinal channel (1 extending through the top to the bottom of the shaft and at its bottom registering with a perforation i in disk I. The walls of channel d? are preferably threaded, as at (1 at its upper end for engagement with the threads of a closure-cap N, desirably provided, it being understood that the capmay be screwed down part way only, thus to leave room for escape of lubricant from the charge-chamber'M, formed in and running to the top of shaft D. It is obvious that two or more discharge chambers M may be formed in the shaft D, and therefore I do not confine myself to the particular disposition shown of such chambers.
Chamber K (in which rests head d of shaft D)may be as large as desired to form a com bined storage-compartment and a passage for oilfrom grooves i to grooves 7c.
. Any suitable force-pump may be used and when used screwed into the upper end of channel at.
. In use any suitable kind of lubricant, preferably lubricant in the form of paste and of the consistency, say, of lard, is forced into the channel (1 such channel thus constituting a storage-chamber. In the use of the machine the lubricant-paste passes through the radial grooves i of disk I (or through the radial channels on the under surface of the shaft, if such are provided, or through both the channels in disk and in end of shaft, where both.
sets a e provided) into' annular passage or chamber K, thence through this chamber into radial grooves 7c and longitudinal grooves it into annular groove L, thence into and out of discharge chamber or chambers M, constituting the oil-outlets, thus effecting a'most thorough and satisfactory lubrication of all parts subjected. to great friction in use and insuring to the'machine a maximum of strength and life. As in the operation of the machine the rollers E are preferably rotatable on shafts D, as the rollers may be of great weight, and as the material operated upon may be coarse ore-bearing material to be crushed or pulverized, it is readily seen what a dam erous friction is engendered if no lubricant evice were employed and how soon this friction would wear away most important parts of the machine were no such lubricant device provided.
I have found that by my system of storagechamber at, radial grooves i, chamber K, grooves k k and L,.and long discharge-outlet M, connected up and operating substantially as described, a machine may .mn guite an indefinite time before the oilsupp y in storage chamber (1 needs replenishing.
The efficiency and object of the' rovision of transverse radial grooves l on 0th surof preferably rotatable thereon; as
passage oreaaose faces of disk I will be obvious. If grooves 73 on one side become clogged, the grooves on the reverse side will still be working and the lubricant will work through these, thus preventing clogging of the lubricant at thelower end of the shaft.
In Figs. 4,5, and 6 I have shown an alternate construction which may be used. In this form the roller (not shown) is referably fixed on or integral with thehhaft (instead in Figs. 1 to 3,) and the shaft Q is preferably rotatable, (instead of preferably rigid, as in Figs. 1 to 3.) Mounted for rotatable movement in head R, which is hinged or pivoted to rollersupporting table B, Fig. 1, is the said shaft Q, havlng'an annular flange g fitting in a similarly-shaped recess in head R, whereby it is retained therein against downward displace-' ment'. A plate g secured to flange g of head R, prevents upward displacement of the shaft.
Acylindrical bushing S, having an-u per head 8, resting on annular ledge q, internally of head R, maybe disposed between shaft Q and head R, a bushing-cap st being desirably secured on the lower end of the bushing. Screwed on u ward-extending portion 9 of plate (1 may e another cap q". Internally of shaftQ is an oil-inlet channel q, terminating in by-passage q, leading transversely through shaft Q to bushing S. In the bushing S may be vertical or longitudinal grooves s -and a lower angular groove .9, Fig. 4. The oil may pass down through groove g", thence through groove q, around groove s and thence up through grooves s to flange q, through grooves T in top of flange s, and thence up through by-passage q in flan eq, to and through oil-exit channel g in sha t Q, and out. If desired, a ring similar to that shown in Fig. 2 maybe employed between the upper surface of head 8 and the under surface of flange'q, this plate being'provided with the oil-distributing grooves, as clearly shown in Fig. 2 and described in connection with this figure.
