JOHN HENRY MARSHALL, OF BELTON, TEXAS.
HARVESTER ATTACHMENT.
SPECIFIC ATION forming part of Letters Patent No. 689,403, dated December 24, 1901.
Application filed May J1, 1901. Serial No. 59,846. (No model.)To all whomn Zt imay con ce;If:
Be it known that I, JOHN HENRY MAR-
SHALL, a citizen of the United States, residing
at Belton, in the county of Bell and State of
5 Texas, have invented a new and useful Har-
vester Attachment, of which the following is
a specification.
This invention relates to attachments for
harvesters and mowing-machines, and more
to particularly to a device for keeping the drive-
wheels of the machine free from accuinula-
tion of earth.
The object is to provide a simple and effi-
cient device of the character specified by the
m5 use of which the harvester and other ma-
chines will be enabled to operate equally as
well on soft muddy ground as on firm ground.
A further object is to provide a wheel scrap-
ing or cleaning attachment that shall com-
20 binesimplicityof construction,efficiency,and
durability in use, and readiness of applica-
tion to use.
Further and more specific details of con-
struction will be hereinafter more fully point-
25 ed out and claimed.
In the accompanying drawings, forming a
part of this specification, and in which like
numerals of reference indicate corresponding
parts, I have shown one form of the embodi-
30 ment of my invention as applied to a har-
vester-wheel, it being understood that the
same ideas may be carried into effect in other
ways without departing from the spirit of the
invention, and in the drawings-
35 Figure 1 is a view in plan exhibiting the
cleaner device as associated with the drive or
master wheel of a harvester. Fig. 2 is a view
in inverted perspective of the scraper de-
tached Fig. 3 is a view in transverse sec-
4o tion taken through the scraping portion of
the device, exhibiting more clearly the con-
tour of the knife in cross-section.
Referring to the drawings, 1 designates the
drive-wheel of a harvester, and 2 the main
45 frame-beams. As these parts may be of the
usual or any preferred construction detailed
description of them is deemed unnecessary.
Secured to the beams 2 by hook-bolts 3 is
the scraper attachment 4, the hook-bolts be-
5o ing passed over the top of the frame-beamsI
and securely clamped there by nuts 5, car-
ried by the lower ends of the bolts. Each endof the bar is formed or provided with an off-
set or lug 6, extending at right angles to the
length of the attachment, these lugs being 55
designed to bear against the frame-beams to
prevent lateral motion of the attachment and
to coact with the bolts 3 in holding the device
securely in position. As will be apparent,
these lugs will operate to remove a larger 6o
part of the strain from the bolts 3. The bar
of metal 7 from which the attachment is con-
structed is preferably of steel and may be of
any desired width and thickness and is pro-
vided at a point intermediate of its ends with 65
an offset 8, constituting the scraper, this off-
set being formed by striking up a length of
the metal at an augle to the face of the bar,
as clearly shown in Fig. 3. In cross-section
this offset is tapered, presenting at its scrap- 70
ing portion a knife-edge 9, this edge to be
moved up as close to the periphery of the
wheel as possible to allow it to clear the bit-
ing-ribs with which the drive-wheel of the
harvester is provided. The edge of the 75
scraper is made somewhat longer than the
width of the wheel and is straight, and from
its terminals the metal is curved downward
and merges into the bar on the outer and
inner surfaces of the bar. By reason of the 8o
fact that the scraper is pitched at an angle to
the face of the bar there will be a space af-
forded in which the periphery of the wheel
may work, thereby permitting the scraper to
be moved up closely to the wheel, as before 85
pointed out.
The outer surface of the scraper operates to
deflect the dirt detached from the wheel and
throw it to its rear, this being due to the fact
that the scraper is located behind the wheel, 90
with the scraping edge disposed downward.
In this instance the attachment is bolted un-
derneath the frame-beams with the lugs 6 pro-
jecting upward and the hooked portion of the
bolts 3 bearing upon the upper side of the 95
frame-beams; but should it be preferred to
bolt the attachment on the upper side of the
frame-beams it will only be necessary to have
the lugs disposed downward and to brmin the
hooks of the bolts 3 into engagement with the io
under side of the frame-beams. As this latter
arrangement will be readily understood, illus-
tration is deemed unnecessary.
It will be observed by reference to Fig. 2
