EVANT, TEXAS.ATTACHMENT FOR CULTIVATORS.
SPECIFICATION forming part of Letters Patent No. 737,378, dated August 25, 1903.
Application filed February 2, 1903, Serial No. 141,519. (No model.)To all whom it may concefl:
Be it known that we, RUFUS 0. FAUBION,
CALVIN W. WORKMAN, and CAVE G. WORK-
MAN, citizens of the United States, residing at
5 Evant, in the county of Coryell and State of
Texas, have invented certain new and useful
Improvements in Attachments .for Cultiva-
tors; and we do declare the following to be a
full, clear, and exact description of the inven-
ro tion, such as will enable others skilled in the
art to which it appertains to make and use the
same.
This invention relates to attachments for
cultivators; and the object is to provide such
15 an attachment whereby the cultivator-beams
may be spread apart or drawn together while
the cultivator is in use and without stopping
the team.
A further object is to provide an attach-
.20 ment for this purpose which will be simple in
construction, easily and quickly operated,
and which may be readily attached to culti-
vators now in use.
With these and other objects in view the
25 invention consists in the construction and ar-
rangement of the parts, as will be hereinafter
more fully described and claimed, reference
being had to the accompanying drawings, in
which-
30 Figure 1 is a perspective view of a portion
of a cultivator, showing the application of the
device. Fig. 2 is a rear elevation of the same.
Fig. 3 is an enlarged sectional view through
the upper end of the attachment, showing
35 the arrangement of the screw.
In the drawings, 1 denotes- the cultivator-
frame. 2 denotes the beams pivotally con-
nected to the same at their forward ends, and
3 denotes the shovels carried by the beams 2.
4o These parts may be of the ordinary or any
approved construction.
4 denotes the attachment for regulating or
adjusting the position of the beams, and it
comprises a pair of angularly-bent arms or
45 levers.5, crossed and pivoted together near
their upper ends after the manner of a pair
of tongs. Each arm or lever 5 consists of a
rod or bar having a vertically-disposed lower
portion 6, the lower end of which is turned
So outwardly and flattened to form horizontally-
disposed attaching members 7, in which- area series of openings or holes, by which said
arms are adjustably connected to the culti-
vator-beams, such attachment being effected
by means of clips 8, which are adapted to 5
embrace the said beams at any desirable point
along their length, said clips being formed
with upwardly-projecting perforated ears or
lugs. 9, between which the members 7 of the
arms are adapted to pass. A pin or bolt 10 6
is passed through the perforation in the ears
9 and through one of the holes in said mem-
bers 7, whereby the said parts are pivotally
connected together. The arms or levers 5 are
bent inwardly at the upper end of the vertical 65
portions 6 at an obtuse angle, as shown at 12,
and the angularly-bent portions of the arms
are arranged to cross each other about mid-
way their length. A pin or bolt 13 is passed
through alined openings formed in said an- 70
gularly-bent portions at their point of cross-
ing, by which means the arms or levers 5 are
pivoted together, a washer 14 being inserted
between the arms, as shown. The upper
ends.of the arms are bent upwardly to form 75
vertically-disposed handle or operating ends -
15, the said ends being forked to form yokes
16, alined openings or eyes 17 being formed
in the upper ends of the yoke members.
18 denotes a bearing-block arranged be- So
tween the forked members of one of said
yokes, and 19 denotes laterally - rojectin--
studs formed on said block, the said studs be-
ing adapted to enter the eyes 17 of said forked
members. 85
20 denotes a longitudinally-disposed open-
ing formed in the block 18.
21 denotes a similarly-constructed block
arranged in the opposite yoke, said block be-
ing provided with a longitudinally-disposed 90
threaded opening 22, which alines with the
opening 20 in the block 18.
23 denotes an operating-screw threaded for
a portion of its length, as shown. This screw
is adapted to pass through the opening in the 95
block 18, and the threaded end of the same
is adapted to engage the threaded opening in
the block 21, the opposite end of the screw be--
ing formed with a crank-handle 24. 25 de-
notes collars.arranged on said screw on each oo
side of the block18, by which means the screw
23 is held against lateral movement, but isI
