UNITED STATES PATENT OFFICE,
GEORGE SCHUBERT, OF WALNUT, TEXAS.
GEAR-SHIFTING MECHANISM FOR HARVESTER-CONVEYERS.
SPECIFICATION forming part of Letters Patent No. 469,275, dated February 23, 1892.
Application filed February 27, 1891. Serial No, 383,082. (No model,)To all whom it may concern:
Be it known that I, GEORGE SCHUBERT, a
citizen of the United States, residing at Wal-
nut, in the county of Bosque and State of
5 Texas, have invented certain new and useful
Improvements in Gear-Shifting Mechanism
for Harvester-Conveyers; and I do hereby de-
clare the following to be a full, clear, and exact
description of the invention, such as will en-
to able others skilled in the art to which it ap-
pertains to make and use the same.
This invention relates to improvements in
gear-shifting mechanism for harvester-con-
veyers, and is especially adapted for the con-
I5 veyer invented by myself and patented Feb-
ruary 17, 1891, No. 446,473.
The object of my improvement is to pro-
vide a locking-lever by which the shifting-
lever is shifted and locked in place after be-
20 ing shifted. I attain these objects by the
mechanism illustrated in the accompanying
drawings, in which-
Figure 1 is a plan view of part of a har-
vester provided with my improvement. Fig.
25 2 is a front view of part of Fig. 1, showing the
shifting-gear in position. Fig. 3 is asectional
view taken on line 1 1, Fig. 1, looking in di-
rection of arrow No. 1, showing parts beyond
the section-line in full lines. Fig. 4 is a de-
30 tail view of the shifting-lever as shown in
Fig. 1, the locking-lever being shown in a
locking position. Figs. 5 and 6 are detail
views of the locking-lever. Figs. 7 and 8 are
detail views of the shifting-lever, showing the
35 locking-lever in dotted lines in position as
when the conveyer is at rest; and Fig. 9 is a
sectional view of the trunnioned step-bearing.
Similar letters referto similarparts through-
out the several views.
40 A designates the platform, which is formed
of upper and lower floors or plates a and a'.
The lower plate a is riveted to the lower flange
of finger-bar and the upper plate is riveted
to the upper face of the finger-bar B. Said
45 plates a and a' are braced and secured to in-
tervening strips b, b', and b2, framed in the
cross-sills d and d', the rear strip b forming
the rear sill of the platform, the strips b' and
b2 forming walls of the passage-way of the
50 conveyer. Openings are made in the upperplate a' for the purpose of the conveyer C
and the devices carried by it.
B' designates a frame-bar secured to post
D and finger-bar B and provided with a cross-
bar D' near its inner or stubbleward end. To 55
said cross-bar D' are secured the posts D2
and D3.
D4 designates a bar secured to post D and
post D2. To the rear of said bar, opposite the
bevel-pinions e and e', is secured the block E, 6o
provided with a pin or studf. To said stud
is pivoted the shifting-lever F, secured thereto
by a spring-pin f'.
D5 designates a bar secured to post D3, ex-
tending grainward and turned down at D', 65
(see Fig. 2,) and then inward and secured to
post D. To the part D' of bar D6 is pivoted
near its center the lever h, having its upper
end slotted, so as to receive the shifting-rod
j, and its lower end trimmed, so as to operate 70
in the slot g' on the front end of lever g.
Said lever g is pivoted near its center to the
under side of the plate a', as shown in Fig.
3. The rear end of said lever g extends into
the passage-way of the conveyer and is op- 75
erated by the latter.
g2 is a rod connecting lever g with lever g'
for the purposes hereinafter described. The
front end of lever g' is pivoted to the plat-
form, and its other end extends toward the 80
rear and into the passage-way of the con-
veyer.
J designates a shaft having is front end
journaled in the trunnioned step-bearing I
and its rear end journaled in the sill b, ex- 85
tending through the sills b' and b2 and pro-
vided with a bevel-pinion J' near its front
end, and a sprocket-wheel b4, located in the
slot A' of the platform and provided with an
endless chain b", by which the conveyer is op- 90
erated.
b is an idler, over which extends the chain
b5 at the grain end of the platform. Said
idler rotates on a shaft b, secured in the strips
b' and b2, as seen in Fig. 1. 95
The lower end of a shaft J3 is journaled in
the trunnioned bearing I and is provided
with a bevel-pinion J2 at its lower end, which
is in constant mesh with bevel -pinion J'.
The upper end of said shaft J3 is journaled too
