EDWIN L.' Y'AN'cnY, or
BATAvA, NEW ronny",-
. Letters Patent No. 97,847, dated December 14, 1869.
IMPROVEMENT IN lHARVBSTER-KNIFE G-RINDBR.
- The Schedule referred to in these Letters Patent and making part of the same.
To all whom it may concern `Bc it known that I, EDWIN'L. YANGEY, of Ba- ."tavia, in the county of Genesee, and State of New York, have .invented a certain new and improved Machine for Grinding Harvester-Gutters,&c.;` audI do hereby declare that theffollowihg is a full and complete description of the construction and operation of the same, reference rbeing had to theaccompanying drawings, making part of this specilication, in which- Figure l is a slide view of the machine. Figure 2, au end view. Figure 3, a view ofthe opposite side of iig. 1.
Like letters of referencerefer to like parts in the 'diii'erent views.
The nature of this in vention relates to a device used in "connection with a' grindstoue, whereby the knives of a harvester are held in proper position to the stone tbrgrinding, so that the cutting edge of the same,
A represents a frame, on which is-supported a stay or standard,
Said stay is secured to the frame by means of a iinger-screw, C, passed through a slot in the rail of the `shall be uniformly true and of the same level.
frame, so that the stay can be adjusted to any place,
on the rail that may be desired. i
I) is the stone, and, as will be seen, is hung to the upper end of the standard ou the shaft E,iiig. 2.
Said stone is driven by the cog-wheel and pinion F G,. ]`ournalled between thecheeks of the standard, as shown in iig. 2.
II are horizontal arms, secured 011e at each end of the top of the frame, to the ext-reine end of which 'are pvoted the standards of, the frame I.
To the rail of s'aid frame is secured v the sickle or knives of the machine., by means. of the `hooks a, lig. 1, passed through the rail, and drawn upon the knives i by the thumb-screws K, as shown in iig. 2.
The practical operation of this machine is as follows: V The knives, yas will be seen, are held parallel with the frame A, thereby bringing them in 'such relation to the stone that the ledge of the section is brought against its side, and on which it is ground.
In `order that the side of the stone shall conform to the speoialungleof the section, the stay or standard supporting the stone is adjusted in such direction as to bring the corner of the stone within the' angle of the two sections, and the basil of the cutting-edge against it. In this position of the stone, the angle of the basil is preserved alike iu each 'section,aud which may he more or less acute or obtuse, asthe nature of the work may require.
The stone once set to the proper angle, one edge of each section is'g'ound while in this position, the scction being pressed against the stone by the springs I), or bya cord and weight, Q, arrange-dier that pur# pose.
other, until the Whole have been ground. 'lhe opposite edges are then ground, bychanging the position of the stone so. as to bring the opposite corner into the angle of two sections, the grinding of which then proceeds as before. 4
By the use of this apparatus,r1nuch labor is saved Vto those grinding the knives, as they are not'required to-hold them 4in their hands to the stone. The grinding is also better done, :is all the knives are ground at the same angle, hence, will be uniform in size, and will, therefore, cut cleaner and casier.
What I claim as my improvement, and desire to secure by Letters Patent, is-
A machine for grinding harvester-blades,consisting of a slotted fra-ine, A, adiustable standard B, ,gearing F G, stone D, hinged frame I, and spring l?, con-A structed, combined, and arranged to operate substantially as described, and for the purpose set forth.
