Improvements to Steam Balance Ploughs.
EDWIN MAXWELL Commercial Traveller and Engineer No. 4, Rutland Road
Bedford Beds do hereby declare the nature of this invention to be as follows:-
I totally destroy the usual idea of having every breast on the balance fram
rigid. Every plough is so fixed or swong to the frame that I obtain an individual
freedom of action to every breast or plough no matter what number there may be
at work on the frame. So that by having every plough or breast quite separate in
action, I am able to secure an uniformity of depth in ploughing, and the action of
the breasts is such that when the plough or breast which is travelling upon its own
small wheels, it is thus enabled to rise and fall according to the inequalities of the
ground it is travelling upon. And every seperate plough is drawn with its own
chain or rope connected to the main axle of large wheels.

Improvements to Steam Balance Flougns.
I, EDWIN MAXWELL of 4, Rutland Road, Bedford, in the County of Bedford-
shire Engineer's Traveller, 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 :-
My invention relates to steam balance ploughs and comprises various improve-
ments hereinafter described.
The main object of my said invention is to provide an improved steam balance
plough by means of which an uniform depth of furrow may be made when
ploughing.
In steam balance ploughs, as now ordinarily made, the various ploughs or breasts
are rigidly attached to the balance frame.
According to my invention I loosely suspend each plough or breast from the
balance-frame by an attachment secured to the rear end of plough beam and the
balance frame, and each plough is separately attached to the axle plate of the large
wheels by its draw bar, or equivalent for same.
I also attach wheels or skids to the plough beam of each plough.
By the aforesaid arrangements each plough has a separate and individual, and
more or less free action in relation to the balance frame.
In the accompanying drawings,
Fig. 1 is a side elevation of a steam balance plough constructed according to my
invention.
Fig. 2. a plan on top of Fig. 1.
Like letters indicate corresponding parts throughout the drawings.
A, is the balance frame, B, B, the ploughs which are suspended from the
frame A hy the fitting C consisting of a bolt D. and clin fitting e. which clips

page_text: the plough beam H, and the latter is free to pivot or hinge lengthways on a pin f,
passing sideways through the clip and plough beam, and also, if preferred, to hinge
or swing sideways on a pin g, passing through the clip and the lower part of the
bolt D.
A spiral spring embraces the bolt D, as shewn, and the plough is free to rise and
fall vertically to a limited extent when at work, the bolt D, working up and down
in a hole provided in the bottom of balance frame, the spiral spring always seeking
to restore the plough to the position shewn in the drawing. I may sometimes also
fit spiral springs E between the bottom of balance frame and upper side of ploughi
beam or head, with the view of steadying the vertical motion of the plough head
and of keeping the entering part or point of plough down.
To each plough beam I fit on each side of same small wheels h, h', or skids i, i.
as preferred. The standards k, k', upon which these wheels and skids are mounted
or attached, can be moved up and down and fixed in any desired vertical position
for the purpose of adjusting the depth of wheels, or skids in relation to the plough
beam.
Any desired number of ploughs or breasts can be attached to a given balance
frame.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
:-
1st. The improved steam balance plough consisting of the, parts constructed,
arranged, and combined substantially as described with reference to the accom-
panying drawings and operating as and for the purpose specified.
2nd. In a balance plough the herein described method of attaching or suspending
each plough or breast B, to the frame, by means of the bolt D, and clip fitting e,
and other devices, all constructed and combined, substantially as described, so that
each plough or breast has a separate action, for the purposes above specified.
Dated this 5th day of December 1894.
