Complete Specification Left, 16th Oct., 1891-Accepted, 21st Nov., 1891
PROVISIONAL SPECIFICATION.
Improvements in or applicable to Horse Hoes, Cultivators, and
other Tilling Implements.
I, JOHN POST LAWRENCE, of 34, Worship Street, in the County of London,
Merchant, do hereby declare the nature of this invention (a communication to me
froin E. W. Burt, of Philadelphia, Pennsylvania, in the United States of America)
to be as follows:-
:-
This invention relates to horse hoes, scarifiers and other implements for tilling
the soil and consists in the novel arrangement of a wheel and lever for regulating
the depth to which such implement enters the soil.
According to my invention the lever carrying the wheel is pivotted to the frame
and the portion of the lever between the said pivot and the wheel axle is bent to
allow a considerable amount of movement relatively with the frame.
In practice the lever for a considerable portion of its length at the wheel-carrying
end thereof is advantageously formed double and the draught head passes through
the space in the said lever. A catch working in conjunction with a notched
segment is provided for locking the lever in any position.

COMPLETE SPECIFICATION.
Improvements in or applicable to Horse Hoes, Cultivators, and
other Tilling Implements.
I, JOHN POST LAWRENCE, of 34, Worship Street, in the County of London,
Merchant, do hereby declare the nature of this invention (a communication to me
from E. W. Burt, of Philadelphia, Pennsylvania, in the United States of America)
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
This invention relates to horse hoes, scarifiers and other implements for tilling
the soil and consists in the novel arrangement of a travelling wheel and lever for
regulating the depth to which such implement enters the soil.
According to my invention the lever carrying the travelling wheel is pivotted to
the frame, and the portion of the lever between the said pivot and the wheel axle
is bent to allow a considerable amount of movement relatively with the frame
without being obstructed.
In practice the lever for the whole or a considerable portion of its length is
advantageously formed double and the draught head passes through the space thus
formed in the said lever at one end. A catch working in conjunction with a notched
segment is provided for locking the lever in any position.
To enable my invention to be fully understood, I will describe how it can be
carried into practice by reference to the accompanying drawing, in which :-
Figure 1 is a perspective view of a horse hoe provided with a travelling wheel
and lever according to my invention for regulating the depth to which the hoes of
the said implement enter the soil:
Figures 2 and 3 are respectively a side view and plan view of the said lever.
Similar reference letters indicate similar or corresponding parts.
a is the lever, and 6 the travelling wheel pivotted therein and adapted to travel
on the ground. The said lever is arranged as shewn so that it shall be within

reach of the operator and is pivotted at c to the frame d of the implement.
shewn in the drawing the portion of the lever between the said pivot and the axle
of the wheel b is bent to avoid its movement being obstructed by the front portion
of the frame d.
The said lever, as shewn in Figure 3, is formed double so as to leave a space e
between the sides thereof, through which space near the end of the lever to which
the wheel bis pivotted, the draught head of the implement passes.
g is the catch on the lever a, and h the notched segment, (secured to the frame of
the hoe), with which the said catch engages, the latter being operated by the rod i
and handle to lock the lever in any position in which it may be placed.
By this construction it will be seen that the wheel b acts as a fulcrum on the
ground, so that, by altering the position of the lever a relatively with the implement
the depth of the hoes in the soil can be regulated.
Although I have described my invention in connection with a horse hoe, it
will be understood that it is equally applicable to cultivators and other tilling
implements.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a horse hoe, cultivator or like implement, the employment of a wheel and
lever for regulating the depth to which the implement enters the soil, arranged and
operating substantially as described.
2. The manufacture and use of the improved horse hoe herein before described and
illustrated in the accompanying drawing.
