UNITED STATES PATENT OFFICE,
AUGUST IHRIGERB, OF CALVERT, TEXAS.
IMPROVEMENT IN PLOWS.
Specification formirg part of Letters Patent No. 157,006, dated November 17, 1874; application fled
July 6, 1874.To all whom it may concern:
Be it known that I, AUGUST IHRINGER, of
Calvert, in the county of Robertson and State
of Texas, have invented a new and Improved
Plow; and I do hereby declare that the fol-
lowing is a full, clear and exact description of
the same, reference being had to the accom-
panying drawing forming a part of this speci-
fication, in which-
Figtue 1 is a side elevation, and Fig. 2 a
plan view.
The invention relates to means whereby the
beam of a plow may be elevated or depressed
at the front end according to the depth to
which it is intended that the plow shall run,
and held securely at several points of adjust-
ment.
These means will first be fully described,
and then pointed out in the claim.
A represents the beam, B the standard, and
C C the handles. The standard B has at the
upper end a tenon that plays loosely in a
longer mortise of the beam, and is held there-
in and thereto by the pivoted straps D D. E
is a pawl that is pivoted to standard B, em-
braces that and the beam, has a cross-bar
catch, e, and two pendent arms, e' e'. A cross-
bolt, F, passes through the end of these arms,
holds the catch e of the pawl to any point of
adjustment on the ratchet G, and is itself pre-
vented from working out by a pin, H.By this means the beam is caused to vi-
brate on the top of standard, to be placed at
different angles thereto, and to occupy sev-
eral relative positions. Thus the depth to
which it is desired to run the plow can always
be regulated with great accuracy, an adjust-
ment made with but little trouble, and the
whole held rigidly in place.
I am aware that a plow-beam has been
passed through the standard, and a yoke
placed below its heel-bolt; but this construc-
tion weakens the beam and renders the plow
liable to choke and wear very rapidly. I am
also aware that a ratchet has been let into the
bottom of beam, and a wedge placed on top to
hold a yoke into the ratchet; but the former
weakens the beam, while the latter is liable to
slip; hence
What I claim is-
The combination of beam A, pivoted stand-
ard B, let thereinto, pivoted yoke or straps D
D, superposed ratchet G, and pawl E, having
arms e' e', all constructed and applied together
as and for the purpose specified.
AUGUST IHINGER.
