RESILIENT CONNECTION FOR PENDULUM-MILLS.
I Specicaton of Letters Patent.
Patented Dec. 31, 1907.'
Application filed May 15. 1907. Serial No. 373.757.
To all whom 'it may concern:
Be it known that I, HERMANN BEER, civil engineer, residing at Magdeburg-Sudenburg, German Em ire, have invented certain new and useful provements in Resilient Connections for Pendulum-Mills, of which the following is a specification. 4
Reference is to be had to the accompanyin drawing, in which igure 1 1s a sectional elevation and Fig. 2 a plan view, partly in section of the improved pendulum mill.
It is known in one-pendulurn-mills to provide a resilient connection between the driving-disk and swivel-joint. In the connection now in use the swivel-joint is pivotally journaled in the driving-disk, and is rotated by the same by means of springs, e. g. elastic cams. As shocks of the grinding-roller, which occur when the same rolls over large uantities of grain, or over unevennesses on t e grinding-surface, are transmitted with great violence by the sti endulum-rod to the ball-bearing of the swive -j oint, the frame of the millis strained very much. Therefore, the swivel-joint in the driving disk is preferably arranged in such a manner that it transmits also the shocks occurring in radial direction elastically to the driving-disk-and thereby to the frame of the mill. To this end the resilient cams journaled in the driving-disk, and acting like springs on the swivel-joint; are distributed uniformly over the inner` circumference of the driving-disk.
Referring now to Fig. 1, the swivel-Joint a is arranged between the surfaces and y in the drivin -disk b in sucha manner that it can be shiIted horizontally in all directions. Between the driving disk b and the swiveljoint a a number of cylindrical india-rubberl buffers c are arranged on the inner circumference of the driving-disk, as best shown in Fig. 2 in such a way that they lie for about one half of their circumference in journallike projections on the swivel-joint a/,while the other half of their circumference lies in similar projections on the driving-disk b. Instead of the india-rubber buffers c other elastic means may be used, for instance, springs. The object attained by this arrangement is that the swivel-joint is not only elastically actuated by the driving-disk, as in the known devices, but that also, at the same time, horizontal shocks occurring in the ball-bearing of the swivel-joint are elastically neutralized by the driving-disk.
Having now fully described and set forth the nature of my said invention, I declare that what I claim is:
1. In a pendulum mill, the combination of a driving pulley, a frame mounted in said pulley and free to slide bodily therein, a pendulum connected by a universal joint with said frame, and yielding connections between said sliding frame and driving pulley.
2. In a pendulum mill, the combination of a driving pulley, a frame mounted in said pulley and free to slide bodily therein in any orizontal direction, a pendulum connected with said frame by a universal joint, and elastic blocks between said frame and pulley.
In witness whereof I have signed this specification in the presence of two Witnesses.
HERMANN BEHR.
