Recently, long time area residents Ken
Doelker and Darrel Clark took on the humongous job of moving a two-ton, antique
threshing machine that had been restored and displayed at the |

Invented in the 1800s, threshing machines separate grain from stalks and
husks, a task which had been done by hand with flails for thousands of years.
Mechanization of this process took much of the drudgery out of farm labor.

According to the plaque on the front of the machine, the Buffalo Pitts
Separator Thresher and Cleaner was originally built in 1877 by the Buffalo Pitts
Company. Founded in 1837 by J.A. and H.A Pitts, the company specialized in
steam-powered engines and vehicles. Its fame came from road-building equipment,
agricultural tractors and threshers, the latter particularly valuable in the
last half of the 19th century as the |

The Buffalo Pitts Separator was purchased around 1900 by a Whitmore
resident named Sharer, who removed the wheels and bolted the threshing machine
down to be run by waterpower from South Cow Creek. In 1905, Charlie Reineke
purchased the thresher, put its wheels back on, and moved it to his ranch on
Clover Creek above Whitmore. |

IMPROVEMENT IN THRASHING-MACHINES.
Specification

of Letters Patent No. 2IO,747, dated
December 10,1878; application filed

To
all whom it may concern:
Be it known that I, LEVI BRONSON, of the city of Buffalo, in
the county of Erie and state of New York, have invented new and useful
improvements in Thrashing-Machines, of which the following is a
specification, reference being had to the accompanying drawings.
My invention relates more especially to that class of threshing
machines in which an endless cellular belt is used for separating the
grain from the straw, and elevating the products of the separation
respectively to the shaking-shoe and the straw carrier.
The object of my
invention is to enable the machine to effect a more complete separation
of the grain from the straw, to prevent the clogging of the parts
connecting the cellular belt with the straw-carrier, and to render the
machine generally more durable and convenient for use.
My invention consists of the particular construction and
arrangement of the parts, as will be hereinafter fully set forth.
In the accompanying drawings, consisting of two sheets, Figure 1
is a longitudinal section of a thrashing-machine provided with my
improvements. Fig. 2 is a horizontal section in line x
x of Fig. 1. Fig. 3 is a fragmentary side elevation of the lower
rear part of the machine. Fog. 4 is a cross-section in line y
y, Fig. 2. Fig. 5 is a front elevation of the triangular picker.
Fig. 6 is an end view thereof.
Like letters of reference refer to like parts in the several
figures.
A represents the main frame of the machine, and A’ a forward extension thereof, raised above the bottom sill of the
main frame, so as to permit the forward wheels to turn under the
extension A’. B is the
thrashing-cylinder and C the concave, of ordinary construction, arranged
in the upper portion of the frame-extension A’.
D is an inclined shaking grain and straw carrier, arranged underneath
the concave C, and extending rearward from the same, for conveying the
grain and straw to the cellular belt E. The shaking carrier D is
composed of an inclined tight bottom plate f
and a straw rake or separator, g,
constructed of longitudinal rods or teeth, secured to a cross-piece, f’, which is supported on the side piece of the shaking |
carrier,
above the bottom plate thereof. The forward end of the carrier D is
supported on flexible arms g’, having their lower ends secured to the extension A’ of the
frame, and the rear end of the carrier is attached to vibrating arms h,
supported in bearings h’,
secured to the main frame A. The carrier is actuated by a rock-arm, H,
connecting with one of the supporting arms
h, and driven by a connecting-rod i,
from a rotating shaft I.
The foot-pulley of the cellular endless belt E is arranged in the
lower forward corner of the main frame A, so that the tight plate f of the carrier D discharges the thrashed grain upon the belt
directly above the pulley e,
as clearly shown in Fig.1.
The belt E is constructed in the usual manner, and carried to a
suitable height for delivering the straw to the straw carrier K and the
grain to the shaker shoe L.
M is a toothed
cylinder, arranged above the rear end of the straw rake
g, so as to seize the straw as it passes over the rake and throw it
upon the upper part of the cellular belt E.
N is a curved hood or deflector, arranged between the
threshing-cylinder B and the toothed cylinder M, for directing the straw
and grain upon the rake g. O
is the triangular rotating picker, arranged between the head of the
cylinder belt E and the foot of the straw-carrier K, for taking the
straw from the belt E and depositing the same upon the carrier K. P P
are two circular plates or washers, preferably made of metal, and
secured to the ends of the angular picker by screws
p, or otherwise. Q are the beveled side guards, secured to the
casing of the machine on the upper side of the belt E, to prevent the
material from escaping over the edges thereof. The guards Q are
constructed with extensions Q’, encircling the upper sides of the
circular plates P, secured to the picker O. so as to prevent the
material from wedging between the end of the picker and the case of the
machine, and wind around the shaft of the picker or obstruct the
bearings thereof.
The shaking-shoe L is constructed in the usual manner, and
driven, by means of a rock-arm, r,
and connecting rod r’, from
a crank-wheel, R, mounted on the
same shaft, I, which |
PAGE 2 OF PATENT
|
drives the shaking-carrier D. The connecting-rods i and r', by which the carrier D and shoe L are respectively actuated, are connected
to the shaft I, or their respective crank-wheels mounted thereon on
opposite sides of the shaft, as clearly shown in Fig. 2, whereby the
strain upon the main frame from actuating these parts is equalized, and
the vibrating of the frame prevented. The pins by which the rods i
and r'
are
attached to their respective crank-wheels are preferably made adjustable
therein, so that the throw of the vibrating carrier and shoe can be
regulated, one independently of the other, as circumstances may
require. In operating. the machine, the grain and straw discharged
from the thrashing-cylinder D are. deflected by the curved hood N upon
the shaking-rake g,
the grain
passing through the spaces between the teeth thereof to the inclined
plate f
underneath,
whence it is delivered upon the endless belt E, while the straw
gradually works toward the end of the rake g,
where it
is seized by the teeth of the cylinder M, by which the straw is thrown
upon the upper part of the belt. In this manner a very complete
separation of the thrashed grain from the straw is effected, the latter
lying loosely upon the cells of the belt E, so as to be readily taken
off by the picker N. The arrangement of the grain and straw carrier D between
the thrashing-cylinder and the belt E increases the length of the
machine considerably, which is very objectionable, as it renders the
machine unwieldy and incapable of turning short. This difficulty is
however entirely overcome in my improved machine by the raised extension
A’ of
the frame, which permits the front wheels to turn under the machine,
and thereby renders the machine capable of turning in a smaller space
than shorter machines of ordinary construction. I claim as my invention- 1. In a thrashing-machine, the main frame A, having the
foot-pulley e
of the
belt E arranged in its lower forward corner, and the forward extension, A’,
raised
above the bottom sill of the main frame to permit the front wheels to
turn under the extension A’,
substantially
as shown and described. |
2. In a thrashing-machine, the main frame A, having the
foot-pulley e
of the
belt E arranged in its lower forward corner, and the forward
extension, A', containing the thrashing mechanism and a grain and
straw carrier, and raised above the bottom sill of the main frame to
permit the front wheels to turn under the extension A', substantially as
shown and described. 3. The combination, with the thrashing-cylinder B,
concave C, cellular belt E, and toothed cylinder M,
arranged above the lower portion of the belt E, of the shaking grain and
straw carrier D, composed of a tight bottom plate, j, arranged to deliver the grain upon the foot of the belt E,
and a rake, g,
carrying
the straw to the toothed cylinder M, by which the straw is thrown upon
the upper portion of the cellular belt, substantially as shown and de·
scribed. 4. The combination, with the belt E and angular picker 0,
provided with circular end plates P P, of the side guards Q, constructed
with extensions Q' encircling the upper portions of the circular plates
P, substantially as and for the purpose set forth. 5. In combination with the thrashing mechanism and
cellular belt E, the shaking straw and grain carrier D, arranged between
the thrashing mechanism and the belt E, and the shaking-shoe L, arranged
on the rear side of the belt E, driving-shaft I, and connecting rods i r', substantially as shown and described. . LEVI
