knife sections to the cutter-bar.
UNITE STATES LESTER RUSSELL, OF OTSEGO, MICHIGAN, ASSIGNOR OF FIVE-TWELFTHS OF HIS RIGHT TO MANSFIELD & HOAG, OF SAlVIE PLACE.
IMPROVEMENT lN HARVESTER-CUTTERS.
Specification forming part of Letters Patent No. 123,731, dated February 13, 1872.
, and useful Improvements in Cutter-Bar; and
do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon making a part of this specification.
The nature of my invention consists in the construction and arrangement of a cutter-bar for reapers and mowers, as will be hereinafter more fully set forth.
In order to enable others skilled in the art to. which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure 1 is a plan view, showing three dif ferent modes of constructing and attachingthe Fig. 2 is a side view of the same. Fig. 3 is a section through line a a: of Fig. 1, and Fig. 4 is a perspective view of a tool used to remove the knife sections.
A represents one of the knife sections, provided at the rear end, near each side, with a dovetail slot, at, fitting over correspondinglydovetailed bars I) b, riveted or otherwise secured to the cutter-bar B. In the center of the knife A, at the rear end, are made two slits I d is beveled or inclined on its under side, so as to raise over the pin 0 as the section is driven to its place. 0 represents a tool, by means of which the spring d is raised for starting out the section in removing the same. A represents a similar knife section, having the dovetailed slots (4, a fitting over the bars I) b and the center spring d",- but, instead of a hole in said spring, the rear end of the same is bent downward, forming a hook, 6 to fit and catch over the rear edge of the cutter-bar B. A represents another knife section, with v.
a dovetailed slot, M, in the center, fitting over a single similarly-dovetailed bar, b and having a hole at the rear end on each side, which.
spring and catch on pins 6 c on the cutterbar, the rear edge of the knife being suitably cut out on the under side to enable the knife to slide over the pins, and also allow of the insertion of the tool 0.
By this means the knife sections may be readily put in and taken out when necessary to grind them or replace broken ones.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
A cutter-bar for reapers and mowers, having the cutter made in sections, and each section provided with one or more dovetailed slots at the base sliding over correspondingly-dovetailed projections or bars on the cutter-bar, and each section held by a portion thereof acting as a spring-catch, all substantially as and for the purposes herein set forth.
In testimony that I claim the foregoing, I have hereunto set my hand this 28th day of November, 1871.
LESTER RUSSELL.
