JOHN H. GRIFFIN AND JAMES S. GRIFFIN, OF HARVARD, ILLINOIS.
IMPROVEMENT IN MACHINES FOR GRINDING CUTTER-BARS FOR HARVESTERS.
Specification forming part of Letters Patent No. 123,890, dated February 20, 1872.
To all whom fit may concern:
Be it known that we, J oIIN H. GRIFFIN and JAMES S. GRIFFIN, of Harvard, in the county of McHenry and State of Illinois, have invented a new and valuable Improvement in Machines for Grinding Mower and Reaper Teeth; and we do hereby declare that the following is afull, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing making a part of this specication, and to the letters and gures of reference marked thereon.
Figure l of the drawing is a representation of a rear view of the body of the horse. Fig. 2 is a top View of the grinding apparatus, showing the method of applying and grinding.
This invention has relation to means for facilitating the grinding of reaper-guards; and it consists in the construction and novel arrangement ofthe horse, hereinafter described.
In the accompanying drawing, the letter A designates the frame ofthe grinding-machine; B, the emery-Wheel. G represents'the body of the horse, having a longitudinal slot formed in it, passing through from its upper to its under side, as indicated at d. E E represent the legs of the horse. These legs are spread at the feet and mounted upon casters z, in order that its movement may be free in any direction. F represents a pvot-bolt, by means of which the reaper-bar G is secured upon the body C ot the horse, in such a manner that a free motion of rotation is permitted about the pivotal point, or, if desired, the bar may be secured rigidly in position upon the body C by tightening the nut h. I represents a crossbar, through which the pivot-bolt F passes. This cross-bar serves as a bearing for the nut h.
This grinding-horse is designed to serve a purpose of great convenience. The heavyflnger-bar, weighing from two hundred to three hundred pounds, can, by its aid, be easily managed and the cutting-edges of the teeth brought in contact with the grinding-Wheel or removed therefrom with great facility.
We claim as our invention- The grinding-horse herein described, consisting of the slotted bodyC, bolt F, casters z, and cross-bar I, substantially.
In testimony that we claim the above we have hereunto subscribed our names in the presence of two witnesses.
JAMES S. GRIFFIN. JOHN HART GRIFFIN. Witnesses:
J. O. WHITNEY, E. C. PORTER.
