Improvements in Ploughs.
We JAMES HORNSBY JOHN INNOCENT and ISAAC TROLLEY all of Spittlegate
Iron Works Grantham Engineers do hereby declare the nature of this invention
to be as follows:-
:-
The invention consists in giving greater facility for raising and lowering the land
wheel of the plough for turning at the end or whenever it may be desired, to run
the plough over the surface of the ground without ploughing.
We use the usual land wheel, axle and leg, the leg is free to slide up or down in
a bracket, on one side of this bracket is mounted a spring bolt which may be operated
by the ploughman without leaving the plough handles.
To regulate the depth of ploughing we mount an adjustable socket on the leg of
the land wheel, when the plough is at work this socket fits up against the underside
of the guide bracket, through which the leg passes, the socket being held in its
proper position by the spring bolt.
To lower the wheel for the plough to pass over the surface of the ground
without ploughing the spring bolt is drawn away from the socket the leg passes
downward through the guide bracket and the spring bolt passes into a bole in
the leg.

JAMES HORNSBY JOHN INNOCENT and ISAAO TROLLEY all of Spittlegate
Iron Works Grantham in the County of Lincoln, Engineers, 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 :-
The invention consists in giving greater facility for raising and lowering the land
wheel of the plough for turning at the end. Or whenever it may be desired to run
the plough over the surface of the ground without ploughing. We use the usual
land wheel, axle, and leg. The leg is free to slide up or down in a bracket, on the
lower side of this bracket is mounted a spring bolt which may be operated by the
ploughman without leaving the plough handles. To regulate the depth of
ploughing we mount an adjustable socket on the leg of the land wheel, when the
plough is at work this socket fits up against the under side of the guide bracket
through which the leg passes, the socket being held in position by a spring bolt,
to lower the land wheel for the plough to pass over the ground without ploughing
the spring bolt is drawn away from the socket on the wheel leg and the leg passes
downwards through the guide bracket and the spring bolt again passes into a hole
at the upper end of the leg thus holding the wheel down until it is desired to
again put the plough into work.

page_text: The drawings only show as much of a plough as is necessary to explain our
invention.
Fig. 1. shows a side elevation with the land wheel up.
Fig. 2. shows a side elevation with the locking bolt passing under the socket E.
Fig. 3. shows a side elevation with the land wheel down.
Fig. 4. shows a plan of the same.
.
A, is the beam, B is the cross slide on which the bracket C. is mounted. C. is the
guide bracket for the land wheel leg, D. is the leg of the land wheel which slides up
or down in the bracket C. to gauge the depth of the ploughing. E. is an adjustable
socket on the wheel leg D which is fixed by the set screw F in the position
required on the leg D. according to the depth it may be desired to plough. In the
casting C. we form a recess for a spring bolt G, and spring H. to the end of the
spring bolt a chain, rod, or cord may be attached passing from the spring bolt to a
lever I jointed near the handle J of the plough. Fig. 1 shows the land wheel up
in the position for ploughing, the end of the spring bolt G. is inserted into a hole K
in the socket E. thus holding the land wheel in a fixed position at the proper depth
for ploughing. When it is desired to throw the plough out of work or to travel
over the land without ploughing, the ploughman can by pressing the lever I
withdraw the spring bolt G. from the hole K. thus allowing the leg D. to slide
downwards. The spring bolt G. passing into a hole in the leg D. (as shown at
Fig. 3) fixes the position of the land wheel so that the plough will travel over the
land without ploughing.
Sometimes in place of passing the end of the spring bolt G into the hole K. as
shown at Fig. 1 we pass the end of the spring bolt under the socket E. as shown
at Fig. 2 thus holding the socket between the bracket C and the spring bolt G.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. In ploughs, the combination of the bracket C. spring bolt G. adjustable.
socket E. with the hole K. and the leg D. substantially as shown and described for
the purpose set forth.
2. In ploughs, the combination of the bracket C. spring bolt G. adjustable
socket E. and the leg D. as described and shown at Fig. 2 of the drawings for the
purpose set forth.
3. The general construction, combination and arrangement of parts forming our
improvements in and relating to ploughs substantially as and for the purpose
hereinbefore set forth and shown in the drawings.
