PROVISIONAL SPECIFICATION.
An Arrangement Giving Greater Facility in Working Wheeled
Ploughs, particularly at Headlands and in Turning.
ANTHONY JOSEPH ROBINSON, Cooldeny Roscren Ireland Gontleman, do hereby
declare the nature of this invention to be as follows:-
The invention consists in the instantaneous lowering and raising of land wheel
(partly automatic) which enables the ploughman to run his share clear of the land
and which greatly facilitates turning out of and into furrow. This is attained by
having one or more adjustable brackets on the wheel standards which brackets
regulate the depth of furrow. The standard is allowed to play loosely thro
loop (which confines standard in position to head of plough). The standard is
released or held immovable as required by spring catch at loop (or spring catches
at loop & bracket) which are controllable between handles of plough and without
stopping horses.

COMPLETE SPECIFICATION.
An Arrangement Giving Greater Facility in Working Wheeled
Ploughs, particularly at Headlands and in Turning.
ANTHONY JOSEPH ROBINSON Cooldeny Roseren Ireland Gentleman, do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
This invention consists in giving the ploughman control over the land wheel
without his leaving the handles of plough by a simple arrangement of lever and
catches he can instantly lower the land wheel so as to run his share clear of the
land and instantly cause it to raise again to the height required for ploughing.
This is attained by the following-
The land wheel standard F Fig. 1. Sheet 1 can play freely through the loop E
from the stop H to the adjustable collar (or bracket) G when required (the collar
or bracket) is adjustable (by set screw N) and can be set to suit the depth of .
furrow.
When the ploughman has his plough in position to enter ground he presses bell
crank K Fig. 2 Sheet 1 which draws back lever 1 Fig. 1. Sheet 1 with pin L
Fig. 2. Sheet 2 (which is kept against standard F by the spring M) raises the
handles of plough so as to throw some weight on land wheel, the standard
immediately slides up until the adjustable collar G looks in catch of 1 and is held
firmly there (see Plate 2 Fig. 1).
When the ploughman wants to run his share clear of the land he presses bell
crauk K which draws back lever I then the standard falls to the stop H the pin L
entering the hole in standard (by the spring M see Plate 2 Fig. 2) which holds
the wheel in the desired position. Figures, 3. 4. & 5 Sheet 2 require no
explanation.
Having now particularly described and ascertained the nature of my inven--
tion and in what manner the same is to be performed I declare that what I
claim is :
1. The instantaneous raising and lowering of the land wheel of ploughs (without

page_text: the ploughman leaving his place between the handles) from the point which will
run his share clear of the land to the height required for ploughing.
2. The land wheel standard playing freely (when required) through the loop
(which confines wheel standard in its place on head of plough) between the two
points as above described.
3. The invention can be easily attached to any wheel plough without any
material change at a very small outlay and very little additional weight.
