IMPROVEMENT IN GFtlNDlNG-MILLS.

Specification forming part of Letters Patent No. 44,000, dated August 30, 1864.

To aZZ whom it may concern:

Be it knownA that I FRIDRICH KLiNK- ERMAN, of Farmers Retreat, Dearborn county, Indiana, haveinvented a new and useful 1mprovementin Grinding-Mills; and I dohereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part ot' this specification.

My invention relates, chiefly, to devices intended to facilitate the tra'mlning of the spindle and to insure freedom of motion and proper and effective action of the spindle and runner.

A represents the husk or frame of a grindingmill.

B is the bed-stone,capable of adjustment to a level by means of wedges C.

D is the foot-beam supporting a pedestal, E, which is itselt'the guide and lateral support of a step, F, whose V-formed ears f rest upon a bridge-tree or lever,Gr, which fulcrums upon the foot-beam D by means of a shifting foot, H, capable of entirely free and unrestricted motion upon said beam. Keys II JJ enable the lateral adjustment of the pedestal E in any direction whatever. Such adjustment is facilitated by the foot'loose arrangement of the bridge-tree G, and the same arrangement also permits the tree to be situated parallel with the foot-beam, or in any oblique position that circumstances may render convenient.

K is the spindle resting on the step F and supported at its upper part by a divided box, L L', resting by lugs l l on ledges m, (one seen,) which project inwardly from the bush M. The lugs l l are provided with rounded edges, which on one side bear against shoulders N (one seen) within the bush, while on the other side the said rounded edges are conned by keys O, (one seen.) This arrangement, while acting to prevent any lateral shifting of the spindle, permits any angular adjustment or disturbance thereof Without,

binding. A Wooden collet, P, let in around the top of the bush, affords a place of attachment for a leather gland, Q, which, inclosing the spindle. guards the bush against the entrance of meal, dust, &c. The top of the box L L is slightly dished for reception of oil or other lubricant, which is fed through an inverted siphon, R.

S is the runner, poised upon the recessed head ofthe spindle by means of a steel cock, T, which is secured in the center of the balance-ryne U, so as to bring the point of poising of the ruimer on a level, or nearly so, with the driving-points ofthe driver V, which are thereby maintained in equal action, even when the spindle is out of tram, so as to avoid the raking action of one edge of the runner upon the bed-stone, which is so great an evil in milling. This relative arrangement ofthe bearing and driving points is due to the inverted position ofthe cock as above explained, the result being a more steady and parallel rotation ofthe runner than heretofore. A lip, u, depending from the ryne and inclosing the head of the spindle, guards the latter from dust.

I claim herein as new and of my invention- 1. The arrangement of foot-beam D, laterally-adjustable pedestal E, vertically-adjustable step F f, bridge-tree G, and shitting foot or fnlcrum H, for the purpose set forth.

2. In combination with a vertically and angularly adjustable mill-spindle, the vibratable box L L' l l', ledges lm, shoulders N, and keys O, substantially as set forth.

In testimony of which invention Ihereunto set my hand.

FRIDRIC EI KLINKERMAN.
