Improvements in Harvesters.
A communication from THE MASSEY-HARRIS COMPANY, LIMITED, of Toronto,
in the County of York, Province of Ontario, Canada.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
M.I.M.E., 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:-
The object of the invention is to provide a light and strongly made finger bar
designed to supply means for supporting the bottom of the grain table and the
canvas roller and it consists essentially of a T-angle bar one-half of the T-head
being longer than the other half, the short half of the T-head being on the bottom
side to which the angle bar which supports the bottom of the grain table is
fastened, the upper or longer side of the T-head supports a strip in which the
canvas rollers are journalled and which is rabbetted to form a recess in which
the edge of the canvas moves substantially as hereinafter more particularly
explained.
Fig. 1 is a perspective view of the grain table provided with the improved
finger bar.
Fig. 2 is an enlarged sectional detail of the improved finger bar and its
attachments.
In the drawing A is the T-headed finger bar to which the guard fingers B are
fastened. The upper half a of the head is deeper than the lower half b. The
angle steel support C is rivetted to the lower half of the T-headed finger bar A.
This support C if provided to carry a wooden bottom D as shown in the drawings
is set at an obtuse angle as indicated, but if a steel bottom is to be used the sides
of the support C are set at right angles to each other. The lower half 6 of the
T-head is just deep enough to form a bracket against which the guard fingers B
may abut. E is a strip secured to the upper half a of the T-head. In this strip
the canvas rollers F are journalled.
On reference to Fig. 2 it will be observed that the top of the strip E is rabbetted
to receive the canvas G thereby preventing the straw from passing below, the canvas
which often occurs and clogs the rollers in machines when this protection is not
provided.
By making the T-head of the finger bar A longer on one side than the other
ample surface and strength is secured for supporting the parts hereinbefore named
and at the same time hold the guard fingers B close to the ground.
With the view of strengthening the finger bar near its connection with the
elevator or in other words at the inner end of the grain table canvas we securely
bolt to the finger bar A an angle plate H as indicated. This plate is shaped as
indicated to project slightly above the upper half a of the T-head and slightly
beyond the end roller of the canvas. This projection slightly raises the straw at
the point where the canvas passes around its end roller so as to bring the straw
within reach of the elevating canvas preventing it following the downward move-
ment of the canvas of the grain table. The plate H also forms a guide to direct
the canvas slats d and keep them in proper position to pass around the end roller
with their canvas.
Having now particularly described and ascertained the nature of the said inven-
tion, as communicated to me by my foreign correspondents, and in what manner
the same is to be performed, I declare that what I claim is :-
Thonded ancla her having one

page_text: half a of the head deeper than the other half b the narrow half b being arranged
to carry the bottom support C while the deep half a is desired to hold the strip E
substantially as and for the purpose specified.
2. The combination with a cutter-bar of an angle plate H securely fastened
to the cutter bar at the inner end of the canvas and shaped so as to project above
the side of the cutter bar to form a guide substantially as and for the purpose
specified.
3. A strip fixed to the finger bar and rabbetted to form a recess for the front
edge of the canvas substantially as and for the purpose specified.
