PROVISIONAL SPECIFICATION.
Improvements relating to Thrashing Machines.
We, FRANK E. BLAKESLEE, and THOMAS MAGUIRE, both of Thompson,
Missoula County, Montana, U.S.A., Gentlemen, do hereby declare the nature of
this invention to be as follows:-
This our invention relates to thrashing machines; but especially to that
part of the mechanism for conveying the straw therefrom and the bundles of corn
thereto.
By this invention, we provide a supporting-plate secured to the framework of the
machine. Upon this plate is journalled a horizontal shaft carrying a bevel pinion
near each end. A pulley is likewise carried by the shaft and is driven by an
endless band deriving its motion from another pulley on the machine. A
horizontally-disposed gear-wheel is mounted on the supporting-plate and has teeth
on its under face and a hub having a central aperture which passes over a vertically-
disposed shaft.
A second horizontal shaft has its inner end supported by the vertically-disposed
shaft aforesaid and carries a bevel-pinion which meshes with the teeth of the
horizontally disposed wheel aforesaid."
A revoluble table or plate is mounted on the axle or vertically disposed shaft
above referred to. The second horizontal shaft, above referred to, carries a pulley
which (by means of an endless band) conveys a rotary motion to a third horizontal
shaft carrying a roller between which and a similar roller extends a traveller
consisting of an endless band having projections upon its surface.
A knife or other suitable sharp instrument is secured to the framework near the
travelling band to cut the binders of the bundles of wheat as they are carried to the
machine by said traveller or conveyer.
By this invention, the conveyer can be moved round to any position
horizontally.

COMPLETE SPECIFICATION.
Improvements relating to Thrashing Machines.
We FRANK E. BLAKESLEE and THOMAS MAGUIRE both of Thompson,
Missoula County Montana, U.S.A. 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 this invention is to provide improved means for transporting
bundles of grain to thrashing machines which will embody features rendering the
device efficient and easily adjustable to any position or point from which the
bundles are to be carried.
We attain this object by the construction illustrated in the accompanying
drawings wherein like letters of reference indicate corresponding parts in the
several views, and in which :-
Fig. 1 is a plan view of the improvements.
Fig. 2 is a bottom plan view of the same one side of which is broken away.

page_text: Fig. 3 is a longitudinal section showing one of the tables broken away, and
Fig. 4 is a detail section through one of the revolving tables.
In the drawings A represents the supporting frame or base having enlarged
circular ends A¹, the central portion between the ends being arranged and adapted
to fit on the table of a thrashing-machine directly in the rear of the cylinder the
same to be attached thereon in any suitable manner.
On the under side of the ends A' are located depending lugs a, having journal
bearings formed therein in which a horizontal shaft B is journaled the shaft being
provided at opposite ends with beveled pinions B' and between one of the pinions
and end of the shaft is located a driving pulley B³, over which the driving belt B³
passes.
Mounted on the upper face of the ends of the supporting frame A are beveled
wheels C having hubs c which rest on the plate and through which the retaining
stub-axles C are passed, the upper ends of the axles being flared to prevent the
same from falling through while the lower ends are passed through openings in the
parts A and carry at their lower ends horizontal shafts D, which have keyed
thereon near their outer ends suitable bevel-pinions D', meshing with the teeth c²,
formed on the under face & at the outer edge of the wheel C, the outer ends of the
shafts D carrying pulley-wheels E, and between the wheels E and bevel-pinions D'
are fixed bearings e, formed in depending arms e¹, extending out from and secured
to the movable cap-plates F, located on top of the wheel C, the cap-plates being
pivoted on the axles C' and formed with depending peripheral flanges f, fitting over
the periphery of the wheel C, as plainly shown in Figs. 3 & 4.
G represents the conveyer-troughs, having journaled in the opposite ends thereof
the drums g, over which the endless carrying-aprons G' provided with suitable
outwardly-projecting pins g', pass. The inner ends of the troughs G are pivotally
secured to brackets F2, rigidly supported by the tables or caps F. The shafts of
the inner drums of the carrying-aprons are extended out beyond the troughs and
have secured thereon pulleys H, over which connecting driving belts I pass, the
opposite ends of which also pass over the pulleys E.
K represents cross-bars extending across the upper face of the carrying-troughs.
These bars have inserted therethrough band-cutting knives L, located centrally
and extending down to a point within the path of the moving bundles.
M are the suspending-cords by which the carrying-troughs are retained in an
inclined position.
It will be understood that the above described construction constitutes carriers
for opposite sides of the machine their construction being the same in every respect,
with the exception of the pulley B³.
In operation power is transmitted through the belt B³ to the shaft B, rotating
the pinions B, which project through suitable apertures in the plate A and mesh
with the teeth of the wheels C, thereby rotating the said wheels, which in turn
rotate the pinions D¹, the shafts D, the pulley-wheels E, and through the medium
of the belts I rotate the drums at the inner ends of the carrying-aprons. When it
is desired to adjust the carrying-aprons, they can be moved laterally by virtue of
the pivoted plates, the pinions D' at the same time being carried around by the
plates, but at all times held in engagement with the teeth of the wheels C. It will
also be seen that the conveyers may be adjusted vertically by virtue of their
pivotal connections with the plates F.
In the construction herein shewn and described we have not mentioned any
particular arrangement for placing or securing the device to the thrashing machine;
but any suitable means may be employed, or the same may be supported
independent of the thrashing-machine on suitable ground supports.
We are aware that many minor changes in the construction and arrangement of
the parts of our device can be made and substituted for those herein shown
and described without in the least departing from the nature and principle of
our invention.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is:-
1. In a bundle carrier for thrashing-machines, the combination, with the
supporting-plate, a horizontal shaft journaled thereon, a bevel-pinion on the shaft,
a pulley on the shaft, a horizontally-disposed gear-wheel mounted on the plate,
having teeth on its under face and an apertured hub, an axle passing through said
hub, a horizontal shaft having its inner end supported by said axle, a bevel-pinion
on the shaft meshing with the teeth of said wheel, a revoluble table or plate
mounted on the axle above the wheel, a pulley on the shaft supported by the axle,
a bearing depending from the cap through which said shaft passes, a conveyer-
trough having an endless apron therein, drums over which said apron passes, a
pulley on one of said drums, and a belt connecting said pulley with the pulley on
the axle-shaft substantially as described.
2. In a bundle-carrier for thrashing-machines, the combination, with a revoluble
table or plate, a conveyer-trough pivotally secured thereto, a gear-wheel below the
plate, an axle passing through said wheel and to which the plate is secured, a

with said gear-wheel a connection between said shaft and the conveyer for
actuating the apron thereof and means for rotating the gear-wheel substantially as
described.
3. In a bundle carrier for thrashing machines, the combination, with a revoluble
table or plate, a conveyer-trough hinged thereto, a gear-wheel below the plate, an
axle passing through the wheel, a shaft, a beveled gear on the shaft, a depending
bearing on the plate through which the shaft passes, a pulley on the outer end of
the shaft a pulley on the conveyer-trough a band connection between the two
