JEFFERSON DAVIS ALLEN AND ERNEST WINSTON, OF MORGAN, TEXAS.
SULKY-PLOW.
SPECIFICATION forming part of Letters Patent No. 612,809, dated October 25, 1898.
Application filed June 15, 1897, Serial No. 640,829, (No model.)To all wh1oim ? t 72ta( COrhce771T:
Be it known that we, JEFFERSON DAVIS
ALLEN and ERNEST WINSTON, citizens of the
United States, residing at Morgan, in the
5 county of Bosque and State of Texas, have
invented a new and useful Sulky-Plow, of
which the following is a specification.
Our invention relates to sulky or wheel
plows, and has for its object to provide a con-
10 struction and arrangement of parts and means
for adjusting the same, whereby the depres-
sion of the plow shovel or shovels may be
regulated to operate efficiently upon uneven
surfaces and whereby the point of the plow
15 shovel or shovels may be more or less de-
pressed, as required by the character of the
work and the soil.
Further objects and advantages of this
invention will appear in the following de-
20 scription, and the novel features thereof will
be particularly pointed out in the appended
claims.
In the drawings, Figure 1 is a perspective
view of a plow constructed in accordance with
25 our invention. Fig. 2 is a side view with the
near wheel omitted, showing the parts in op-
erative position in full lines and with the
plow-beam tilted to elevate the plow in dot-
ted lines. Fig. 3 is a detail transverse sec-
30 tion of the means for adjusting the lateral
position of the tilting beam.
Similar numerals of reference indicate cor-
responding parts in all the figures of the draw-
ings.
35 1 designates a tongue, to the rear end of
which is secured the straight member 2 of a
sectional axle carrying a near wheel 3, said
axle - section being extended in the opposite
direction from said wheel beyond its point of
40 attachment to the tongue and being secured
to an angular side bar 4. Mounted for rock-
ing movement in alined bearings 5 and 6 in
the tongue and said side bar, respectively,
in front of the straight axle-section 2, and
45 hence eccentrically with relation thereto, is a
cranked axle-section 7, the crank-arm 8 of
which extends rearwardly to bring the spin-
dle 9 approximately in vertical alinement
with the straight axle-section to carry the off
5o wheel 3". The term "eccentrically" is em-
ployed in this description to indicate that
said straight and cranked axle - sections aremounted neither concentrically nor coaxially,
but are mounted with their axes transversely
disposed out of alinement to arrange the 55
spindle portion of the cranked axle-section
approximately in the vertical plane of the
straight axle - section. The relative adjust-
ment of the axle - sections is controlled by
means of a lever 10, pivoted upon said side bar 6o
4 and connected by a rigid link or pitman 11
with the cranked axle-section at a point near
the spindle thereof. Locking devices for this
lever may consist, as illustrated in the draw-
ings, of a toothed segment 12, engaged by a 65
pawl 13. It will be seen that in either posi-
tion of the cranked axle-section the draft ap-
plied thereto by the frame, which includes
the tongue and the side bar 4, is in the direc-
tion of the crank thereof, thereby relieving 70
the adjusting-lever of unnecessary strain in
operation. Secured to the opposite side of
the tongue from said side bar 4 is an angle
side bar 4", also having its rear end attached
to the straight axle-section contiguous to the 75
plane of the near wheel 3.
Mounted upon the straight axle-section is
a tilting frame, consisting of a tilting beam
14 and a brace 15, which are rigidly connected
together in rear of said axle-section and are 8o
provided with alined bearings 14" and 15a, re-
spectively, which are fitted to slide upon said
straight axle - section, whereby the tilting
beam may be adjusted laterally with relation
to the tongue for a purpose hereinafter ex- 85
plained. This tilting beam carries a plow-
beam 16, which extends loosely through the
U-shaped clip 17, located near the rear end
of the tilting beam, and which is loosely con-
nected at its front end with said tilting beam, 90
whereby draft applied directly to the plow-
beam may operate without straining the frame
of the machine. In order to facilitate such
application of draft to the plow-beam, the lat-
ter is provided at its front end with a clevis 95
18, and the whiffletree 19 is shown attached
thereto, said whiffletree having no connection
with the tongue.
It will be understood that any desired con-
struction of plow-shovel may be attached to 1o0
the standard 20, formed by the rear end of
the plow-beam, or a plurality or gang of plow-
shovels may be attached thereto in any of the
ordinary ways well known in this art, the
