Specification of Letters Patent.
Application flledlebruary 12, 1. Serial 110,800,789.
. all whom, it may concern:
Be it known that I, HARRIET A. HIGBEE, a citizen of thefUnited States, and resident of Worcester, in the county of Worcester and State of Massachusetts, have 'made a certain new and useful Invention in Grinding Machines; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilledin the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters or figures of re erence marked thereon, whichsform a part of this specification.
Figure 1, is a central vertical section. Fig. 2, is a horizontal section. Fig. 3, is a top View of the race way. Fig. 4, is a sectional view of the'same. Fig. 5, is partial top view of upper grinding plate. Fig. 6, is a detail of hinge. Fig. 7, is a detail of frame arm.
The invention has relation to grinding machines, chiefly designed for the purpose of reducing grain, and the invention consists in the novel construction and combinations of parts as hereinafter set forth.
In the accompanying drawings illustrat-.
ing the invention, the letter a, designates the lower or main supporting frame, having a vertical central bearing 6, for the shaft 0, of the lower grinding disk or plate 01. This portion of the frame is also provided with arms 6, having threaded hearings. for the reception of adjusting and leveling screws.
A. race-way f, of annular form, and having an inner annular bearing flange (7, is supported by the leveling screws h, of the arms of themain frame, said screws-having, at their upper ends, axial lugs which engage bearings of the race-way, and prevent it from turning.
The lower grinding plate is' of flat or disk form, and isprovided with a, strong hub portion which is supported by the collar k, secured'to. the u per end of the main shaft, and connected-t ereto by the dowel pin at k. Interspaced: radial fins m, are disposed around the bottom of this grinding late, and serve to setup a circulation air, when the plate is rotating, this serving to aid in keeping the plate cool. The dress of this plate is radial, and is designed to disof the lower grinding plate.
portion of the frame which supports the charge'at the perimeter, the discharge tube n, being connected to the race way. This.
grinding plate is provided with an annular peripheral discharging portion p, which moves over the guard flange g,'of.theraceway; and with a guide flange g, which diing disk or plate .9, which is provided with a peripheral guard portion 1*, and an annular guide flange u, designed to move near the marginal portion of the eccentric opening of the cover t.
The upper grinding plate is provided with a central eye to, and a feed tube v, extends upward therefrom, and-is connected to the hopper 2. The axial center of the upper grinding plate is therefore eccentric to that The upper hopper and fixes the position of the feed tube and upper grinding plate is indicated at 3. It is provided with arms 4,. which correspond to the arms e, of the main frame, and serve to, receive the upper ends of the adjusting screws. Usually, however, I refer to utilize-two of these screws as hlnge screws, indicated at 5, as one screw 6, having its upper and lower ends provided withthreads of op osite inclination, will serve all purposes 0 adjustment.
The eye of the upper grinding plate is provlded with a bevel bearing 7, to engage 1n a frictional manner the beveled lower end of thebearing socket 8,.in which is re- 'ceived the lower end of the tube shaft 9, which bears in the hub 2, of the upper frame, and is supported in position thereon by means of the nut 10. Below the hub, the tube shaft 9, is provided with a collar 11, which takes the thrust of the grinding plate through the bearing socket 8. The latter is provided with an annular groove 12, to engage a holding pin connected to the tube shaft, and'serving to prevent the bearing socket from falling oil the tube shaft,,when
the grinding plate is removed, and allowing the oil to escape.
The upper end of the tube shaft is threadedto engage an adjusting nut 13, which bears against the hopper, and serves to raise Patented Apr. 1, i913.
The race-way is provided w1th a.
In the operation of this mill, the lower.
grinding plate is positively rotated by means of its central shaft and suitable gearing in connect-ion therewith. At the same time the upper eccentric grinding plate to which the lower grinding plate is adjusted by means of the raceway turns slowly under the grinding pressure, its rotation being eccentric to that of the lower grinding plate. The diameter of the upper plate, in the construction shown, is less than that of the lower plate, the difference being a little less than the eccentricity, so that the upper plate will have a slight over lap, whereby the grinding surface is extended without enlarging the lower plate. The edges of these grinding plates are usually provided with corrugations or teeth, as at 15, in order to move and gather under the centrifugal action any particles of grain which may fall on the bearing flange 0f the race way, be-
tween said edges and the wall thereof.
Having described the invention what I claim, and desire to secure by Letters Patw cut is: p
1. In a grinding machine-having an upper adjustable frame-portion, the comblna- -.tion with a peripheral-discharge lower grinding plate, of an eccentrically mounted upper grinding plate, a raceway engaging the circumferential portion of the lower grinding plate, a cover for said raceway having an eccentric opening for the upper grinding plate, and means for adjusting the raceway.
2. In a grinding machine, the combinaadjustable feed-tube, a raceway engaging 1 the peripheral-discharge grinding plate, means of adjustment for said raceway, and a raceway cover having an eccentric opening.
In testimony whereof I aflix my signature, in presence of two witnesses.
