I, WILLIAM BRENTON, of Polbathic, St. Germans, in the county of Cornwall,
Millwright and Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to mowing and reaping machines and comprises improvements
in the finger-bar and fingers as hereinafter described.
According to my present invention I construct a finger bar with longitudinal
grooves, serrations, or corrugations, into which corresponding lugs, ribs, or projections
on the fingers are adapted to fit.
These grooves or serrations in combination with the lugs, ribs, or projections, tend
to prevent any lateral movement of the fingers.
The front lower edge of the finger bar is preferably square (especially in cases
where the knife sections are placed under the knife bar) and the fingers are
also formed with a square angle. By this construction of the finger bar and
fingers a larger contact surface exists between the same than has heretofore been the
case.

Improvements in Mowing and Reaping Machines.
I, WILLIAM BRENTON, of Polbathic, St. Germans, in the County of Cornwall, Mill-
wright and Engineer, do hereby declare the nature of this invention and in what manner
the same is to be performed to be particularly described and ascertained in and by
the following statement
My invention relates to mowing and reaping machines and comprises improvements
in the finger bar and fingers as hereinafter described.
According to my present invention I roll or otherwise construct a finger-bar with
longitudinal grooves, serrations, or corrugations into which corresponding lugs, ribs,
or projections on the fingers are adapted to fit.
These grooves or serrations in combination with the lugs, ribs, or projections, tend
to prevent any lateral movement of the fingers.
The front lower edge of the finger-bar may be square or inclined and the fingers
are also formed with a corresponding angle. By this construction of the finger-bar
and fingers a larger contact surface exists between the same than has heretofore been
the case.
In order that my said invention may be understood I will describe how the
same may be carried into practice by reference to the accompanying drawing in
which
Figure 1 is a plan of a portion of a finger-bar constructed according to my
invention with the improved finger applied thereto, and
Figure 2 is a sectional side elevation of the same.
a is the finger-bar, b is the finger, and c is the bolt for securing the said finger to
the bar.
d, d are grooves which are formed in the finger-bar and e, e are ribs formed on the
fingers and adapted to enter the said grooves. As shown in figure 1 these ribs
extend only partially across the face of the finger, as indicated by dotted lines, and
thus constitute lugs. The said lugs when the finger is in place and secured by
the bolt c, enable the finger to be held much more firmly than would otherwise be the
case.
Although I have described the grooves as being formed in the bar and the lugs or
ribs on the fingers, it is to be, understood that longitudinal ribs may be formed upon
the bar and corresponding grooves or recesses in the fingers.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is :-
1. In a mowing or reaping machine, a finger-bar having ribs or grooves, in

page_text: combination with fingers having corresponding grooves or ribs, substantially as, and
for the purpose described.
2. In a mowing and reaping machine a finger bar having grooves as described in
combination with a finger having lugs adapted to fit into the said grooves, substantially
as described with reference to the accompanying drawing.
3. The manufacture and use of the improved finger-bar and finger hereinbefore
described.
