drawings showing simply an ordinary form
of single shovel. In order, however, to adapt
the apparatus for the use of shovels of differ-
ent sizes, wherein the side draft varies more
5 or less, it is desirable to provide for the lat-
eral adjustment of the plow-beam support-
ing-frame, and hence the sliding connection
of the tilting beam with the straight axle-sec-
tion, said frame being held at the desired lat-
.o eral adjustment by means of an adjustable
stop, consisting of a screw 21, threaded trans-
versely in the rear end of the draft-beam and
provided with a lock-nut 22, the extremity of
said screw being adapted to bear against one
15 side of the tilting beam to limit the move-
ment thereof toward the center of the sulky-
frame, the tendency of the tilting beam, due
to the side pressure upon the plow-shovel, be-
ing toward the draft-beam.
20 Mounted upon the sulky-frame, in opera-
tive relation with the front end of the tilting
beam, is a crank-shaft 23, of which the cross-
bar 24 is parallel with the straight axle-sec-
tion and is adapted to bear upon the upper
25 surface of the extremity of the tilting beam,
the latter being preferably provided with a
terminal arm 25, having a hooked extremity
26, in which said cross-bar is free to slide and
in which it fits when the parts are in opera-
30 tive position. The cross-bar is of greater
length than the width of the tilting beam,
whereby the latter may be adjusted laterally
by the means hereinbefore described without
removing it from the desired position with re-
35 lation to the crank-shaft. Fulcrumed upon
the side bar 4" is an operating-lever 27, loosely
connected, as by a chain 28, with the crank-
shaft, whereby the forward movement of the
free end of the lever is adapted to draw the
40 crank-shaft downwardly to depress the front
end of the tilting beam and thereby elevate
the plow-shovel. Suitable locking devices,
including a toothed segment 20 and a pawl
30, are employed to secure the lever, and
45 hence the crank-shaft and plow-beam, in the
desired positions. (See dotted lines in Fig.
2.) When the crank-shaft is released, the
weight of the rear portion of the plow-beam
and the shovel serves to depress them into
50 contact with the soil, as shown in full lines in
said figure. It is frequently necessary, how-
ever, to employ positive means for holding
the plow-shovel depressed in order to keep
it from running out of the soil, and to ac-
55 complish this we provide a foot-lever 31, hav-
ing a cam-face 32 to bear against the crank-
shaft when the latter is in its normal posi-
tion, the effect of said foot-lever being to ele-
vate the cranked portion of said shaft and
6o thereby depress the portions of the tilting
beam and plow-beam which are in rear of the
straight axle-section.
In addition to the above construction we
also employ means for depressing the point
65 or nose of the plow-shovel without affecting
the general position of the shovel, said means
consisting of a crank - lever 33, fulcrumedupon the tilting beam in advance of the
straight axle-section and having one of its
arms connected by means of a-rigid link or 70
pitman 34 with the front end of the plow-
beam, said lever being provided with suitable
locking devices, including a toothed segment
35 and a pawl 36. By swinging said lever
forwardly its approximately horizontal arm 75
is depressed to correspondingly move the
front end of the plow-beam and, thereby tilt
the shovel, and thus depress the point or nose
thereof, this adjustment being wholly inde-
pendent of the rocking adj ustment of the tilt- 8o
ing beam.
From the above description it will be seen
that the straight and cranked axle-sections 2
and 7, respectively, are eccentrically mounted
or with their centers out of transverse aline- 85
ment, the straight axle-section being mounted
in the frame near its rear end, while the
cranked section is mounted in the frame near
its front end, with its crank-arm 8 extending
rearwardly to dispose the spindle portion 9 90
approximately in the vertical plane of the
straight axle-section.
Various changes in the form, proportion,
and the minor details of construction maybe
resorted to without departing from the spirit 95
or sacrificing any of the advantages of this
invention.
Having described our invention, what we
claim is-
. Ina sulky-plow, the combination with a 1oo
sulky-frame and a transverse axle carried
thereby, of a tilting frame mounted upon a
straight portion of the axle for swinging move-
ment in a vertical plane, and lateral sliding
movement parallel with said axle, and carry- 105
ing a plow-beam, means for holding the tilt-
ing frame at the desired lateral adjustment,
and other means for securing said tilting
frame at the desired angular adjustment,
substantially as specified. I I0
2. In a sulky-plow, the combination with a
sulky-frame and an axle, of a tilting frame
fulcrumed upon said axle, means for securing
the frame at the desired inclination, a plow-
beam loosely mounted to yield forwardly and i 5
rearwardly upon the tilting frame, and draft
devices connected with the plow-beam, sub-
stantially as specified.
3. In a sulky-plow, the combination with a
sulky-frame and an axle, of a tilting frame 120
mounted for lateral adjustment upon the axle
and carrying a plow-beam, means for secur-
ing the tilting frame at the desired inclina-
tion, and an adjustable stop for limiting the
lateral movement of the tilting frame, sub- 125
stantially as specified.
4. In a sulky-plow, the combination with a
sulky-frame and an axle, of a tilting frame
fulcrumed upon the axle for transverse ad-
justment, and carrying a plow-beam, means 130
for securing the tilting frame at the desired
angular adjustment, and an adjustable stop
consisting of a screw threaded in a fixed mem-
ber of the sulky-frame and bearing terminally2
