Definitions
- Figure 1 represents a top view, partly in section, of my improved finger-bar.
- Fig. 2 is a vertical transverse section of the same.
- Each finger is made of platesteel, and can be cut out at one operation, requiring afterward but a little further manipulation than the turning on of a screw-thread at the rear end for the reception of a nut, b.
- the slope on the face of the finger-bar serves in part to preventlongitudinal displacement of the finger, and to take some strain off the nut b, which bears against the flange a,-the latter being notched or perforated for the reception of the threaded parts of the fingers.
- the bar A is notched to admit beveledged downward projections d of the fingers. These projections keep the fingers down on the bar, and prevent their backward displacement.
- the fingers are placed in such proximity to each other on the fin ger-bar that there will be two or three or more for every V-knife of the cutter-bar. This arrangement facilitates the operation of the knives.

UNITED STATES PATENT QFFIGE CALVIN D. READ, OF AYER, MASSACHUSETTS.
IMPROVEMENT IN CUTTING APPARATUS FOR HARVESII'ERS.
Specification forming part of Letters Patent No: 128,326, dated June 25, 1872.
Specification describing a new and Improved Harvester Finger-Bar and Finger, invented by CALVIN D. READ, of Ayer, in the county of Middlesex and State of Massachusetts.
Figure 1 represents a top view, partly in section, of my improved finger-bar. Fig. 2 is a vertical transverse section of the same.
Similar letters of reference indicate correspondin g parts.
- and with an upwardly-projecting flange, a, at
the back edge. Each finger is made of platesteel, and can be cut out at one operation, requiring afterward but a little further manipulation than the turning on of a screw-thread at the rear end for the reception of a nut, b. The slope on the face of the finger-bar serves in part to preventlongitudinal displacement of the finger, and to take some strain off the nut b, which bears against the flange a,-the latter being notched or perforated for the reception of the threaded parts of the fingers. In front the bar A is notched to admit beveledged downward projections d of the fingers. These projections keep the fingers down on the bar, and prevent their backward displacement. The fingers are placed in such proximity to each other on the fin ger-bar that there will be two or three or more for every V-knife of the cutter-bar. This arrangement facilitates the operation of the knives.
Having thus described my invention, I claim as new and desire to secure by Letters Patent The combination of the fingers B, provided with downward projections 11 and threaded rear ends, with the finger-bar A, notched at its front edge, and having the perforated flange a, as shown and described.
CALVIN D. READ.
