To a whom/ it ntcty concern:
Be it known that 1, JAMES W. FULLER, Jr,
a citizen of the United States, residing at Catasauqua, in the county of Lehigh and State of Pennsylvania, have invented certain new and useful Improvements in Pulverizing or Grinding Mills, of which the following is a specification.
My invention has relation in a pulverizing or grinding mill to means for supporting the driving-shaft thereof and forming as well a receptacle for a lubricating fluid for maintaining the actuating mechanism of said shaft at all times in proper working condition and to means connected with said shaft and support for taking up wear of the shaft and in such connection it relates particularly to the general construction and arrangement of said means for the said purposes.
The principal objects of my invention are, first, to provide a pulverizing or grinding mill with means for supporting the driving-shaft for forming a receptacle for a lubricating fluid and portions of the actuating mechanism for said shaft; second, to provide the supporting means with a removable flange adapted to confine the lubricant to the receptacle, and,'third, to provide the supporting means with means to take up the wear of the driving-shaft.
The nature and characteristic features of my invention-will be more fully understood from the following description, taken in connection with the accompanying drawings, forming part hereof, in which Figure 1 is a view illustrating, partly in side elevation and partly in vertical central section, a pulverizing or grinding mill, showing means for supporting the drivingshaft and forming a receptacle for a lubricating fluid, means for confining the lubricant to said receptacle, and of actuating mechanism for said shaft, partlylocated in said receptacle, and means for taking up wear of the shaft in a vertical plane, and of means supported by the shaft forming part of the grinding mechanism of the mill and for elevating matter therein embodying main features of my present invention. Fig. 2 is a horizontal sectional view taken on the line 0c of Fig. 1. Fig. 3 is a detailed. view, enlarged, illustrating, partly in section and partly in elevation, the lower portion of the means for supporting the driving-shaft of the mill and of means for taking up or compensating for wear of the shaft.
I Referring to the drawings, A represents a base or support having an annular flange a, which rests upon a suitable foundation a. The annular portion a merges into a downwardly-extending dish shaped portion (1 having an upwardly-inclined central portion a forming a bearing for a vertical drivingshaft 72. Preferably formed integral with the portions (1 and a of the base are arranged extensions a, forked at their free ends a for engaging a spanner or yoke a, connected therewith by means of bolts M. The exten-' sion a forms a chamber a for the reception of a boX a", secured thereto by means of bolts. a. The boX surrounds the lower portion of the shaft 1) and extends slightly beyond the same, forming a flange a, surrounding a cupshape bearing a, supported by the spanner or yoke a and engaged by an adjusting-bolt (1 held in any position given by a j am-nut a. The cup-shape bearing a has a central bearing (L15, of preferably chilled metal, which shown in Fig. 3. The cup-shape bearing a" serves to support the driving-shaft b by means of a bolt 6, of tool-steel or other suitable material, andcontacting with the bearing-surface (L thereof. The bolt 5 is removably inserted in the shaft b and is prevented from turning therein, preferably by, a key I), as shown in Fig. 3.
The annular portion a, 'in conjunction with the downwardly and upwardly extending portions a and a of the support for the driving-shaft 5, forms a chamber or receptacle a for receiving and holding a lubricating fluid. To the shaft 1) is secured a gear wheel 0, the toothed portion 0 of which terminates in the dee est part of the chamber or receptacle (1 w llOll is so shaped in crosssection as to substantially coverthe toothed portion 0 of the gear-wheel c with lubricating fluid. Adjacent to the upper edge of the annular portion a of the support A is arranged an upwardly and inwardly inclined flange d, preferably consisting of sections secured by means of bolts (1 to the flange a.
c meshes a gear-wheel c driven by a shaft 0 from any suitable source of power. (Not shown.) The shaft 0 is supported by a bearing 0 secured to the flange a of the base A, and the flange (1 leaves a suflicient opening to permit the gear-wheel c to engage the gear-wheel c. When the shaft 1) is "rotated by means of the gear-wheels c and c and may be formed either integral therewith, as
'VVith the toothed portion of the gear-wheel throw the same out of the receptacle a This,
however, is effectually prevented by the flange d, which serves as a baffle-plate to thus confine the lubricant to the said receptacle a. Any portion of the lubricating fluid lashing or thrown against the baflle-plate (i will be conducted by the same back into the said receptacle.
In order to provide a liquid-tight joint between the sections of the flange d, each section is provided with a portion (1 overlapping the abutting ends of the sections. The flange a of the base or support A serves to support a standard a, the open spaces 6 of which are closed, preferably, by metal plates (2 thus forming a closed chamber 3, by means of which arrangement dust or other extraneous matter is prevented from entering the lubricant in the receptacle c and also preventing any exit of the lubricant through the standard 6. Moreover, the gear-wheels c and c are protected from extraneous matter.
To the base A is suitably secured a casing f, which supports a basket 9, partially formed of screens g and an outer casing 9 The basket is closed at its upper end by a ring h and a plate It, carrying a bearing 7L3 for the upper end of the driving-shaft b. The plate h is provided with an opening h serving as an inlet for matter to be ground from a feeding device h, as shown in Fig. 1 of the drawings. Within the casing f the driving-shaft b is provided with a carrier for the support of grinding-balls k, which are held by the same opposite an annulus or ring f To the carrier i is removably secured a frame Z, supporting two series of superposed and obliquelyarranged wings or vanes Z and Z The weight of the carrier 'i, balls 7c, frame Z, wings or vanes Z and Z and platform m is sustained by the shaft 1), which in turn is supported by the bolt 6 and bearing a. It follows that during rapid rotation of the shaft 6 and mechanism sustained by the same considerable wear takes place. This, however, is compensated for by the bolt 6 and the portion e of the bearing a, by the making of the belt I) preferably of tool-steel and the bearing c of chilled iron. hen it becomes necessary to take up wear between the bolt 1) and bearing-surface a, this can be readily accomplished by simply and quickly raising the bearing e in the spanner or yoke a by means of the belt a. If it becorres necessary to replace the bearing a and the bolt 1), this can readily be done by removing the spanner or yoke a to free the lower portion of the shaft and to thereby permit of ready access to the same for such pur ose.
Having t ius described the nature and objects of my invention, what I claim as new, and desire to secure by Letters Patent, is
In a pulverizing or grinding will, a base having an annular depression substantially V-shape in cross-section and adapted to form. a receptacle for a lubricant, a gear-wheel substantially V-shape in cross-section and terminating with the toothed portion thereof in the depression of said base, a sectional flange carried by said base and arranged substantially parallel to the toothed portion of said gear-wheel and substantially covering the depression of said base, said flange adapted when said wheel is rotated, to form a baffle-plate for the lubricant raised by the same and to conduct the lubricant back over the toothed portion of said wheel.
In testimony whereof I have hereunto set my signature in the presence of two subscribing witnesses.
