JOSEPH F. GUSTARD, OF COPLAY, PENNSYLVNIA.
CENTRIFUGAL GRINDING-MILL.
no. sensori.
I Specication of Letters Patent.
Patented .rune i5, 190e.
Application filed ecember 23, 1908. Serial No. 468,940.
To all whom it may concern.'
Be it known that i, Josnin F. CUsTARD, of Coplay, in the county'of Lehigh and State of Pennsylvania, have invented certain new Cir and useful improvements in Centrifugal Grinding-Mills; and l hereby declare that the following is a full, clear, and exact de- .scription thereof, reference being had to the accompanying drawings, which form part of this specification.
rlhis invention is an improvement in crushing or pulverizing mills of the centrifugal roller type, and it relates articularly to the means for suspending t e crushing roll shaft and for lubricating the crushing roll so that there will be less wear on the parts, the roll will be more securely -suspended'; cost of repairs and maintenance will be lessened the parts can be assembled with greater facility, and the roll 'bearing will be more perfectly lubricated. V
The invention therefore consists in the novel construction ofthe rocker-head by rmly clamp shaft 8.
which the roll shaft is suspended; land also in the novel construction of the roll-shaft to insure bearings.
I will now describe the invention with reference to the accompanying drawings, which illustrate the same as applied to a centrifugal roller mill of a well known type. In the drawings-Fi ure l is a sectional view of part of such mil showing the rocker-A l'iead, and roll-shaft in section. Fig. 2 is an enlarged top plan view of tle rockerliead and shaftf Fig. '3 is a side view of Fig. 2.
The rocker-head 1 -is provided with a transverse sleeve 1 a, for a horizontal shaft 2; and with a vertical sleeve 1e for the upright roll-shaft 3; the said sleeves therefore lie at right angles, and are formed in 'one common or integral casting. The sleeve 1a is split longitudinally as at 1b, and is provided with a pair of perforated ears 1 at opposite sides of the slit for the passage ofclamp bolts 4, which are ,rovided with nuts la and by which the slp the shaft 2. The sleeve 1e is also longitudinally s lit, as at lf, and is provided on opposite si es of the slit with perforated lugs lg and 1h, for the passage of bolts 5 and 5a, which are provided with nuts 5b, 5c to tighten the bolts and cause tho sleeve to proper lubrication of the roll- Tlie shaft 2 is short and is journaled in by the bo eeve can be securely clamped to bearings in a lbifurcated carrier attached tothe main'shaft 7 a of usual construction, so that when shaft 7'ya isrota'ted, the rocker-head is carried'around in anorbital path. The shaft S-is suspended from i the rocker-head, and its upper end fastened in sleeve le by the clamp bolts 5, 5a. The
' shaft Sis provided with anotch or groove 3 near its ulpper end, whichnotch is engaged t 5f, said bolt serving as a key to or support 7 prevent the shaft 3 turningI in the sleeve le y and also to prevent shaft Blmoving end wise in the sleeve, and also as a means for clamping sleeve l'e tightly around shaft 3. Shaft 8 is provided with a flange 3b near its lower end, and below the flange is a. crushing-roll 8, which is journaled on the lower end of the shaft, and is upheld by a sleeve 18`,`secured to the roll and .supported upon the flange 3b in the usual manner. The u per end of sleeve 8b enters a recess 1m in the llbwer end of sleeve 16,as shown. As the shaft 7 a is rotated the support 7 carries shaft 8 around in an orbital pat and roll 8 moves outward by centrifugal force,l and ycrushes material against the side walls of crushing rin 9, as usual. In order to lubricate the rol 8, the shaft 3` is provided with a large bore 3c in its'upper end, forming an oil chamber. The upper end of this bore is internally threaded, 'and shafts are positioned, the wedges are re-A moved and the bolts tightened, clamping the sleeves firmly to the shafts. This construction does away with the threads and top nuts heretofore employed to connect` the rollshaft to the rocker-head. And the interior oil chamber inshaft 3 db es away with tho usual oil cups and exterior appliances which are ycumbersome and disadvantageous.
Having described my invention what l claim as new and desire to secure by Letters Patent is: j
1. In a centrifugal grinding mill, the combination of a rotatable support, a rockerhead pivotally mounted thereon having a vertical split sleeve and clamping bolts transfixing said sleeve with a shaft having its upper end confined in said sleeve, and notched shaft is prevented, and a. crushing roll on said shaft.l
' 2. In a eentrifugalgrinding mill, the ooml bination of a rotatable support, a horizontal shaft thereon, a. rocker-head having a horizontal split sleeve clam ed on said shaft and also having a vertical sp it sleeve, and clamping bolts transxing said 'vertical sleeve, one
y of said bolts being set nearerthe axis of the sleeve then the other; with a shaft havingits upper end confined in said sleeve and notched for engagement with said inner clam ing bolt whereby longitudinal'movement' o the 15 shaft isfprevented, and a crushingroll on the lower end of said shaft. f In testimony that I claim the 'foregoing as my own, I affix my signature in presencel of two witnesses.
