FREDRIC EDWARD WHITHAM, OF SOWERBY BRIDGE, ENGLAND.
MACHINE FOR GRINDING.
SPECIFICATION forming part of Letters Patent No. 664,202, dated DecemberplS, 1900.
Application filed September 15, 1900. Serial No. 30,208. (No model.)
T0 all whom t may concern.-
Be it known that I, FREDRIC EDWARD WHITHAM, a subject of` the Queen'of Great Britain, residing at Sowerby Bridge, in the county of York, England, have invented certain new and useful Improvements in AMachines for Grinding or Reducing Lime, Ashes, Sandstone, Limestone, Quartz, and other Minerals or Materials, of which the following is a specication. v
My invention relates chiefly to a means of adjusting or balancing underdriven millstones, whereby such millstones may by a slight adjustment be exactly balanced, so as to compensate for wear at any given part. Also by my improved means, method, and
position of fixing same, hereinafter described,
there is no resistance to or absorption of a large amount of the motive power required to drive the pan carrying the bed or millstone, such resistance and absorption of power being occasioned in ordinary underdriven millstones by the several projecting parts of the balancing mechanism (which is usually fixed radially from the center underneath the pan) coming in contact with the atmosphere as the pan revolves, the resistance thus set up increasing with the speed of the pan or millstone, so that in high-driven millstones the power absorbed by this means is enormous.
With my improvements there are no projecting parts which can offer any resistance in the manner aforesaid.
My improvements are mainly applicable to machines for grindin-g lime, engine-ashes, sandstone, and other materials to a iine powder for use as mortar, to machines for grinding limestone and other materials for cement, and to machines for the reduction of quartz and other ores, but it may also be applied to mills for grinding certain kinds of grain and for other analogous purposes.
In the drawings, Figure l is an elevation, partly in section, of an underdriven millstone with my improved means for balancing applied. Fig. 2 is a plan view of one of the rings employed in balancing. Fig-3 is a sectional elevation of Fig. 2. Fig. 4 is a sectional elevation showing my improvements applied and in combination with a wood ring or packing for obtainin g the vertical plane or ascending plane of balancerequired.
In carrying out my said invention I employ two or, if necessary, three annular rings A, fitting around the pan or frame B, which carries the bed or millstone C. Each of the said rings A is cast solid at D, preferably of rectangular cross-section, for a portion of its length-say one-siXth-the remainder being of a corresponding hollow section. (See Figs. 2 and 3.) These rings may berotated or moved preferably about the outer periphery of the pan B upon a flange B or upon a metal disk E, carrying the millstone C, (see Figs. 1 and 4, respectively,) by any suitable or convenient means, either separately or together, so as to adj ust the positionof either or of the several solid parts D. Such adjustment allows of the center of gravity being displaced to any required extent in any desired direction, so compensating for uneven density or wear of the millstone and maintaining the whole in sition by any suitable means, so as to facilitate despatch in releasing, adjusting, and xing same. I also employ a suitable wood ring or rings N or of other light durable material of the desired depth. This wood ringNis placed between the balance-rings A and the {iange B of the pan B or the disk E or between the rings A themselves, as desired, preferablybefore the millstone is mounted within the machine and is for assisting in and obtaining the adjustment of the vertical or ascending plane of balance. By these means while the rings A adjust and obtain a perfect horizontal balance the said rings, in combination with the ring or packing N, fixv and maintain the ascending or vertical balance of the millstone and pan B or disk E, the depth of the wood rings N varying according to the distance the rings A require to be raised in ascertaining the aforesaid vertical balance.
IOO
The pan B has a central conical sleeve F on which the driven bed or millstone C fits, the said sleeve terminating in a dome-shaped bearing G for the end of the driving-shaft H. This driving-shaft H carries a cam J, which 'engages with a projection Aor dog K on the inner side of the conical sleeve.
I am aware that means have been employed for balancing millstones, but
W'hat I claim as my invention, and desire to secure by Letters Patent, is-
1. The combination, with a'revoluble millstone,and abase-plate which revolves with it; of superposed balancing-rings resting,r on the said base-plate,and acoVer-plate overlapping the said balancing-rings and arranged in contact with the said stone, substantially as set forth.
2. The combination, with a revoluble millstone, and a base-plate which revolves with it; of superposed balancing-rings resting on the said base-plate, adistance-piece N of light material arranged between the base-plate and the lower balancing-ring, and a cover-plate overlapping the said balancing-rings and arranged in contact with the said stone, sub- Stantially as set forth.
3. The combination, with a revoluble millstone, and a pan which revolves with it `and is provided with a base-plate at its lower part of superposed balancing-rings encircling the' periphery of the said pan and restingon the said base-plate, and a cover-plate arranged in contact with the said stone and overlapping the said pan and balancing-rings, substantially as set forth.
In testimony whereof I have hereunto set my hand in the presence of two witnesses.
