LAFAYETTE HORN, OF CHOICE, TEXAS.
MOTOR-DRIVEN IMPLEMENT. ' -Specification of Letters Patent. Patented Nov. 19,1912.
Application fled November 28, 1911. Serial No. 662,872.To all whom it may concern:
Be it known that I, LAFAYETME HORN, a
citizen of the United States, residing at
Choice, in the county of Shelby and State
5 of Texas, have invented certain new and
useful Improvements in Motor-Driven Im-
plements, of which the following is a speci-
fication.
My invention relates to improvements in
10 plows and similar agricultural implements,
and is designed to be used as a plow, a
cultivator, or a planter, the employment of
various attachments for these different pur-
poses being required to convert one imple-
15 ment into another.
The object of the invention is the pro-
vision of a motor-driven implement of this
type which may be manipulated and guided
with facility by the plowman, which is
20 simple in construction and operation, com-
paratively cheap in first cost, durable, and
capable of conversion for use in a variety
of different ways.
The invention consists essentially in the
25 novel combinations and arrangements of
parts as hereinafter set forth and claimed.
In the accompanying drawings I have
illustrated one example of the. physical em-
bodiment of my invention constructed ac-
30 cording to the best mode I have so far de-
vised for the practical application of the
principles.
Figure 1 is a plan.view of an agricultural
implement illustrating my invention. Fig.
35 2 is a side elevation of Fig. 1, with the
addition thereto of a fuel tank and con-
nections.
In the exemplifying structure illustrat-
ing the invention in the drawings I have
40 utilized a cultivator, but it will be under-
stood that the invention contemplates the
use of other attachments in lieu of the cul-
tivator attachment shown, the latter being
here 'used for purposes of convenience in
45 showing and describing the invention.
The motor driven implement in its pre-
ferred embodiment is supported upon a rec-
tanguiar% frame, including a pair of hori-
zontal side, beams 1 and end connections. 2,
50 2. The frame is suspended or hung upon
the' large single traction wheel 3 by means
of the axle 4 and bearings 5, 5, and at the
rear are fastened the upwardly and rear-
wardly extending plow handles 6, 6, for
55 guiding the implement.
At the front end of the frame is locatedthe motor, 7, which as illustrated in the
present instance-comprises a pair of internal
combustion engines, which receive fuel
from the tank 8 at the rear of the imple- 60
ment, by. connecting pipe 9. These engines
which comprise the motor may be increased
in number, but for convenience I have illus-
trated only two, and these are connected to
the traction wheel 3 from their cranks 10, 65
through duplicate connections, at each side
of the traction wheel, comprising the pair
of bevel gears 11, 12, the shaft 13, supported
in bearings 14 on the side beams, and the
bevel gear 15, which meshes with the large 70
wheel 16, attached to the spokes 17 of the
traction wheel 3. Through these connected
parts the traction wheel 3 is rotated from
the motor 7.
The driving motor may be disconnected 75
from the driven mechanism by means of
the clutch mechanism illustrated, one for
each engine and comprising a clutch mem-
ber 18 adapted to be. engaged by the com-
plementary member 19, whose spool 20 may 80
be moved on the shaft 13 by means of the
forked U-shaped draw bar 21 to which the
link 22 is connected. The other end of the
link is pivotally connected to the lower end
of the actuating lever 23 which lever is 85
suitably fulcrumed, at 24 to the cross bar
25 of the handles. With the parts as shown
in Fig. 2 of the drawings, the forward
movement of the upper end of the actuating
lever will disconnect the clutch members, 90
and render the connection between the driv-
ing mechanism and the driven mechanism,
inoperative.
As hereinbefore stated the implement as
illustrated is adapted to be used as a cuti- 95
vator, the spring tooth attachment 26, serv-
ing the functions of a cultivator.
One of the most advantageous and meri-
torious features of the implement as .illus-
trated is the ease with which the implement 100
may be steered. This feature is due to the
fact that the entire implement is supported
at a single point on the one traction wheel
3. This single point of support permits the
plowman who guides the implement by 105
holding the handles 6, to turn the imple-
ment with facility when he has reached the
end of a row, or if plowing upon a circular
field, the plow may be held to its steady
course without difficulty or excessive 'exer- 110
tion.
I desire it to be understood that the im-1,044,655.
