Letters Patent No. 70,071, dated October 22, 1867.

TO ALL WHOM IT MAY CONCERN:
Be it known that we, ALFRED BROWN, IIORATIO D. Woncnsrnn, and Annan M. GnIswoLn Ganier, Kankakee county, State of Illinois, have made certain new and useful improvements in Sickle-Guards; and we do hereby declare the following to be a full and exact description of the same, reference being had to the drawings that accompany and Form a part of these speeifii-atirms, in which- Figure I is a perspective view of sickle-guard, with steel plate 13 fastened to the guard by'two countersunk screws.
Figure II, sectional view of steel plate.
, of the town of Figure III, perspective view of the steel plate, one showing a smooth edge, the other a sickle edge.
Letter A, sickle-guard; letter B, detachable steel plate; letters C in position and fastened to the guard; letters (I (l, openings in top of be inserted or removed, as desired; letters E E, flanges on under side of plate B, to give additional firmness and stability to it, thus avoiding too great a strain upon the scrcws'C C; letter B, Fig. III, plate with smooth edge; letter G, Fig. III, plate with sickle edge.
-The object of our invention is not simply to provide the steel plate 13, in order to give better cutting edges, as this has already been done, but to provide a readily detachable plate, for the purpose of sharpening or substitoting new ones, when required, without the necessity of disturbing any other part or the machine. The steel plate B has bevelled edges. The two holes (Z (l'in the upper part of the guard enable us to take out the screws C G and readily remove the plate for the purpose of g rinding or filing whenever it becomes dull. This plate may be made with a smooth edge for cutting grass, or with a sickle edge for cutting grain, as shown in Fig. III.
gas of this invention will be readily appreciatcd by every one accustomed to working in or reaping machines, as it is well known that after using them any considerable time the edges of the guard become rounded and dull, and consequently require more power, and fail to do as good work as at first. The sharpening of these plates when attached to the guard is extremely diilicult. This difliculty is obviated by the use of this plate, which is so easily removed and sharpened. i
What we claim as our invention, and desire to secure by Letters Patent, is
The detachable steel plate B, provided with the flanges e e, I stantially as described, and for the purposes set forth.
C, screws by which the plate B is kept guard, through which the screws C may 10 wing either with or without the sickle edges, sub
