Year: 1897

page_text: Date of Application, 27th Mar., 1897-Accepted, 27th Nov., 1897
First, to provide a cultivator which is supported on casters and may be raised and
lowered thereon to different depths in the ground, or elevated so as to clear the
ground in driving it.
Second, to provide a cultivator with reversible teeth of which either end may
be turned toward the ground.
Third, to provide a cultivator with sharp-edged teeth so that the weeds may be
cut and spread and not tangled and crowded up in front of the teeth.
Fourth, to provide a cultivator in which the teeth are arranged in such a spread
and zig-zag order that the weeds have no chance to fill up between them even when
the cultivator frame is adjusted to a very narrow gate.
Fifth, to provide a cultivator with casters or carrier wheels in which sand cannot
get in between the journals and spoil the bearing, as is so often the case with
common cultivator wheels, especially those of the small type, having their center
near the ground.
Sixth, to provide a cultivator which may be adjusted as to its width, without
loosening any bolts or nuts, simply by a latch or dog lever, placed within easy
reach of the driver.
With these and other objects in view my invention consists in the novel con-
struction and arrangement of parts illustrated in the accompanying drawings,
in which,
Figure 1, is a top or plan view of my cultivator.
Fig. 2, is a side elevation of Fig. 1.
Fig. 3, is a rear cross section of the frame as on the line a, a, in Fig. 1.
Fig. 4, is an enlarged detail view of one of the cultivator teeth.
Fig. 5, is a cross section on the line b, b, in Fig. 4.
Fig. 6, is an enlarged sectional rear view of one of the casters, as on the
line c, c, in Fig. 2.
Referring to the various parts in the drawings by reference numerals, 7, may
be termed the draw head of the cultivator. This head is provided with a spring-
covered hook 8, by which the cultivator is drawn by a hitching link in the usual
manner. In the rear of said head is secured a central bar 9, and to the sides of
the head are pivotally secured at 10, the front ends of the two side bars 11, and 12,
which may be spread or closed by swinging them in the horizontal plan on their

page_text: pivots 10. Near the rear end of the center bar 9, I secure pivotally at 13, the
rear end of an oblique bar 14, which has its front end pivotally supported by a
socket or guide 15, sliding upon the bar 12, so that the bars 14, and 12, are self-
adjustably connected.
Upon the center bar 9, is rigidly secured an upright 16, which is provided in
its front side with indentures 17, in which engages the pointed end or tooth 18,
of a spring-held thumb lever 19, pivoted at 20, to a head 21, sliding upon the
upright 16, and having a hand-hole 22, adapted to be grasped in the same hand
of which the fingers press the lever 19, so as to unlock it from the indentures 17.
The sliding head 21, is pivotally connected with the outer frame bars 11, and 12,
by the oblique braces 23, (best shown in Fig. 3). The whole frame thus described
is mounted on three large casters 24, of which the round, stems 25, are journaled
one in the draw head 7, and the other two in the enlarged rear ends 26, of the
side bars 11, and 12. The frame is adjustable up and down on the stems of the
casters by means of the collars 27, thumb set-screws 28," and indentures 29, pro-
vided in the sides of the stems for the screws to engage. The wheels 30, of the
casters are journaled on the bolt or axle 31, (best shown in Fig. 6), which is
rigidly secured in the fork 32. The hub 33, of the wheel is provided in each side
with an annular cavity 34, in which I place the soft packing 35, and then insert the
suugly fitted collars 36, which are secured on the axle 31, by pins as 37, or set
screws as 38, so that sand and dirt is excluded from the journal, partly by the
collars. 36, and partly by the packings 35, as a further safeguard.
The cultivator teeth are each made up of a forwardly bent arm 38, bolted to
the frame bars as at 39, and may preferably have strengthening braces as 40,
and an angularly bent plate or tooth proper, as 41, which is secured at its center
to the lower and forwardly bent portion of the arm 38, by a bolt 42, and nut 43,
so that either end of the plate 41, may be turned downward and used in the
ground. The head of the bolt 42, and the foremost angular edge 44, of the
plate 41, and 45, of the arm 38, are formed so sharp as to cut and divide the weeds
and vines. It will be observed, that on ordinary cultivators, of similar con-
struction as mine, the teeth are usually arranged upon two bars in about the
order shown on the bar 11, in Fig. 1, and the consequence is that when the bars
are adjusted, in, close proximity to each other the teeth of both bars stand abreast
in pairs, which, especially with the foremost teeth, results in a gathering and
heaping up of the weeds upon the teeth, which is obviated in my machine by
having the teeth arranged as shown in Fig. 1, three of them upon one side bar
and, one on the other side bar near its rear end; one tooth on the center bar and
one upon the oblique bar 14. This places the lines in which the teeth move equal
distances apart and still leaves no two teeth to come so near a transverse line
that they can prevent each other from getting rid of the weeds. The only two teeth
tlíat come in a transverse line are those at the rear ends of the side bars, and they
are so far apart that in using the cultivator they will never come close enough
together to co-operate in gathering the weeds.
In operation, the hitching clevis is slipped under the spring 46, into the hook 8;
and the machine drawn to the field on its large casters 24, which it will be
observed are very open in the forks straddling. the wheels, so as to prevent
clogging of vines around the wheels; the set screws 27, are then loosened and the
frame lowered so that the teeth cut the desired depth into the ground, the width of the
machine is then fixed by pressing on the lever 19, and moving the sliding head 21,
up or down so that the side bars 11, and 12, close or spread to the desired point;
the lever 19, is then released and by the spring 47, caused to interlock its lower
end in the upright 16. In so regulating the width of the machine the guide 15,
slides on the bar 12, and adjusts itself to the required place.

It is obvious that this cultivator may have a seat for the driver if so desired,
and a pair of handles for the driver to rest his hands on and help steer the
machine if he walks behind it; but seats and handles being old and common are
not shown in my drawings as the novel features can be understood without them. ***

page_text: Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed I declare that what
I claim is:-
1. A cultivator having a frame consisting of a draw head with a hitching
hook at its front end, a central frame bar extending rearwardly therefrom, two
side bars pivotally secured to and extending rearwardly from the drawhead, an
oblique frame bar pivoted near the rear end of the central bar and having its
front end pivoted to a block or guide sliding upon one of the side bars, and teeth
arranged upon all of said bars and means for spreading the side bars, substan-
tially as shown and described and for the purpose set forth.
2. The cultivator having a draw head and a rigid central frame bar as 9,
extending therefrom, the side frame bars 11, and 12, hinged or pivoted thereto,
with their front ends, the oblique bar 14, pivoted to the central bar and having
its other end slidingly connected to one of the side bars and three cultivator
teeth secured to one of the side bars and one to the rear end of the opposite side
her; one tooth to the central bar and one near the middle of the oblique frame
bar, and means for spreading, closing, raising and lowering the frame, substan-
tially as and for the purpose set forth.
