CHARLES V. DYER, OF HALLSVILLE, TEXAS.
IMPROVEMENT IN REVOLVING CONICAL MOLD-BOARDS.
Specification forming part of Letters Patent No. 191,086, dated May 22, 1877; application filed
December 28, 1874.To all whom it may concern:
Be it known that I, CHARLES VALENTINE
DYER, of Hallsville, in the county of Harri.
son and State of Texas, have invented a new
and useful Improvement in Revolving Coni-
cal Mold-Board Plow, of which the following
is a specification:
Figure 1 is a top view of my improved
plow. Fig. 2is a vertical section of the same,
taken through the line x x, Fig. 1. Fig. 3 is
a front view of the plow-plate and the lower
part of the.couical mold-board.
Similar letters of reference indicate corre-
sponding parts.
The invention is an improvement in the
class of plows having a cylindrical rotating
mold-board; and it relates to the construction
and arrangement of parts, as hereinafter de-
scribed, whereby the conical mold-boards are
caused to rotate as the machine advances.
The invention consists in the combination
of the revolving cones with the notched plow-
plates and the plow beams, and in the combi-
nation of the endless chains and the chain-
wheels with the spindles of the cones, with
the plow-beams, and with the axle and the
wheels, as hereinafter fully described.
A represents a frame to which the draft is
attached, and in bearings attached to which
the axle Brevolves. To the ends of the axle
B are attached the wheels C, so that the said
wheels may carry the said axle with them in
their revolution. D are the plow-beams, to
the upper and lower sides of the forward ends
of which are pivoted, by bolts or rivets, the
ends of straps E that pass around the axle B,
as shown in Figs. 1 and 2, so that the rear
ends of the plow-beams D may have a free
vertical and lateral movement.
The rear parts of the beams D are curved
downward to serve as standards for the plows
F, which are bolted to their lower ends. The
middle upper parts of the plows F are notched,
as shown in Fig. 2.
To the lower parts of the standards of the
beams D are attached or upon them are formed
pivots G, which project upward into the
notches of the plow-plates F, and enter holesin the apices of the cones H. In the bases of
the cones H are secured spindles I, which re-
volve in bearings attached to the beams 1),
and which carry the cones H with them in
their revolution.
To the upper ends of the spindles I, above
the beams D, are attached chain-wheels or
pulleys J, around which pass the endless
chains or bands K, which also pass around
the double chain-wheels or pulleys L pivoted
to the supports M. The supports M are at-
tached to the forward parts of the beams D,
as shown in Figs. 1and 2. Around the double
pulleys L also pass the endless chains N, which
pass around pulleys or chain-wheels O attached
to the axle B.
By this construction, as the machine is
drawn forward the cones H are revolved, so
as to turn the soil as it rises upon the plows
F to one side, and at the same time break it
up and pulverize it.
P are knives or scrapers, the lower ends of
which are pivoted to the lower parts of the
beams D in such positions that when their
upper ends are move l forward their forward
edges may come in contact with the surface
of the cones H, and scrape off any soil that
may adhere to said cones. The upper ends
of the knives or scrapers P project into such
a position that they nay be conveniently
reached and operated by the plowman, and
may be provided with spring-catches, or other
suitable devices for holding them in either
position. Q are the handles, which are at-
tached to the plow-beams D to enable the
plowman to readily guide the plows.
Having thus described my invention, I claim
as new and desire to secure by Letters Pat-
ent-
The combination of the endless chains K
and N and the chain-wheels J L O with the
spindles I of the cones H, with the plow-beams
D, and with the axle B and wheels C, sub.
stantially as herein shown and described.
CHARLES VALENTINE DYER.
