MILLSTONE DRIVER AND RYND.
SPECIFICATION forming part of Letters Patent No. 241,456, dated May 10, 1881. Application filed January 1, 1881. (No model.)
' To all whom it may concern and exact description, reference being had to the accompanying drawings, forming part of this specification.
My improvement relates to a device for communicating motion from the spindle to the stone, the construction being such as to allow the runner to run true, though the spindle may be out of tram or sprung.
lVlillstones as usually driven admit of no accurate running-balance, owing to the construction of the driving device. The ordinary driving device consists of rigid arms or driver extending-from the spindle and engaging the stone at points below the point of balance at the cock-head. The consequence is that if either the driver or its bearin gs upon the stone are not true, or the spindle. is not in tram, or sprung, that the runner cannot run true, for reasons which will be obvious.
In the drawings, Figure 1 shows the improvement chiefly in axial section, with the stones mostly in elevation. Fig. 2 shows the eye-lining, in section at m 00 Fig. 4, with the other parts in elevation. Fig. 3 is a section at :0 00 Fig. 4 is a top view of the improvement. Fig. 5 is a horizontal section at a: as, Fig. 3. Fig. 6 is a horizontal section at m :r, Fig. 3.
I have shown my improvement as applied to an upper runner. Itmay, of course, be applied equally well to a lower runner.
A is the bed-stone. B is the runner. O is the eye of the runner and D is the metal linin g of the same, with an inturned circular flange, cl, which gives means for the attachment of the circular balance piece or rynd E 1 1 cast in one piece and composed of a flange, e,
at top, extending beneath and bolted to the flange d, as shown at F, and a flat circular part, 6'', connected to the flange by bars 6, between which are side openings, 6 for the outward passage of the grain. The rynd E has in the bottom a recess to receive the cockeye-block G.
e are lugs extending downward at opposite sides of the rynd, and having vertical slots 0', to receive studs h, projecting from the driverring H. The studs h are at opposite sides of the ring,"and at points intermediate between them project similar studs h, which occupy slots 1" in the lugs or extensions '5 at the upper edge of the drive-cylinden I. The drive-cylindcr surrounds the spindle K, as shown, andis supported on the ends 7c of a pivot-pin, 70, passing through the spindle, in order to equalize the pressure of the driving-power, said ends 70 7c occupying slots or recesses i at the lower edge of the drive-cylinder. Thus it will be seen that there is the utmost freedom of ac commodation between the balance-rynd and the spindle, as the drive-ring and its connections form a universal joint between them. K is the cock-head at the upper end of the spindle, forming the point of suspension of the runner, and sustaining the whole weight of the same.
Now, supposing the spindle should not be exactly vertical or "in tram, it will be seen that my driving device would not interpose any obstacle toprevent the stone running in a horizo tal position, because there would be perfectfreedom of movement between the cockeyepiece E and the spindle.
I will call attention to an important point of construction in this connection, viz: The upper end ofthe cock-head is in the same plane as the axis of the driving-studs h it. Thus in all the deviations of the stone relatively with the spindle or the springing of the spindle the movement would be made upon the point of the cockhead-bearing, as a center of movement, and there would be no binding of parts, checking the easy and perfect adjustment. It will be seen that the parts would adapt themselves to compensate for the imperfections in their constructions, without tending to throw the stone out of its horizontal position.
It will be observed that the rynd E can be readily taken out by unscrewing the bolts F, and again returned to exact position. Thus any necessary repairs may easily be made to this part.
I claim herein as my invention- 1. The combination, with the spindle K, having pin 7c, and the drive-cylinder I, provided with slots t" 4?, of the driving-ring H, having studs h h, rynd E, having the flange c,circnlar part 0 and slotted lugs e, substantially as described, and for the purpose set forth.
