Description
lhrtd Stabat JONES, or LOWELL, WISCONSIN.
'Letters Patent No. 98,693, dated January 11, 1870.
IMPROVEMENT IN SICKLE-GRINDER The Schedule referred to in these Letters Patent and making part of the same.
To all Iwhom 'it 'may concern Be it known that I, A. B. J ONES, of Lowell, in the county of Dodge, and State of Wisconsin, have invented anew and useful Improvement in Sickle- Grinders; and I do hereby declare that the following is a fnll and exact description thereof, reference being had to the accompanying drawings, and letters marked thereon, making a part of this description, in which- Figure l is a perspective representation of my invention.
Figure 2, the part claimed to be new, removed from the other parts.
The present invention relates to an improvement in that class of grinders whichis `designed more especially for sharpening the knives of mowers and rcapers, without removing them from the sickle-bar; and
Its nature consists in combining, with an emerywheel and suitable gearing, an adjustable spring-stand, which is used to support the knives of the sickle-bar,
and which is so constructed that the knives may beY ground on any bevel required.
C C represent an Ordinary iron stand, which is prois provided witha hole, D, for the convenience of bolting it fast to a bench or other convenient foundation, and to which an adj ustable standard, B, provided with a slot, E, isheld by means of a bolt and nut`F.
rlhis standard B supports the shaft of adrive-wlleel, (l, and one end of a shaft-,11, which supports a pinion,- T, and an emery-wheel, L, the other end of the shaft being supported hy a curved arm, I, fastened to the standard B at J, as shown in iig. 1.
` The stand C C supports an arm, A, which is provided with a socket, M, at its upper end, in which the lower end of a coil spring, N, is placed.
The vupper end of this spring lits into a socket, O, which is rigidly fastened to a bed-plate, P, on which the sickle-bar Q is placed when the knives V are being ground, the plate P having a depression, R, made in the central part of its upper side, permits the stone L to pass down'between the knives,` and a holt, S, iig. 2, beingput through the sockets O M, and through the cent-re of the spring N, holds the latter in place.
By means of this construction and arrangement, the sickle-bar Q, may have any angie or position, relative to the periphery of' the stone L, which is required, or may be necessary to grind the knives V.
The operation is very simple,'reqn,ring only that the wheel G be put in motion, and the sickle-bar Q so held and turned on the bed P as to properly bring the knives under the wheel L, said bed readily inclining in any required direction for this purpose.
Having thus described myinvention,
What I claim, and desire to secure by Letters Patent of the United States, is-
The adj ustahle bed P, provided with a depression, It, and socket O, in combination with the spring N,
holt S, and socket M, arranged with lreference to the` stand C C, standard B, wheel G, pinion T, shaft H, and wheel L, as set forth.
A. B. JONES.
