PROVISIONAL SPECIFICATION.
Improvements in and relating to Revolving Cultivators for Steam
and other Power.
LOUIS JOHN BRIGGS, of Priory Farm Stamford in the County of Lincoln
Farmer do hereby declare the nature of this invention to be as follows:-
My invention consists of an improved form of revolving forks, or tines, and is
applicable to existing drags, for steam cultivators, or can be constructed with a
special frame, and travelling wheels, or can be used in combination with any
ordinary drag, and has for its object, the more effective breaking up, and cleaning
of the soil.
I mount, in rear of the usual fixed tines, a roller, or rollers, in suitable bearings,
and which are provided with a number of tines or forks, or spuds, which are set at
intervals round the shaft, or bosses, and extending the full width of drag, the tines
may be more or less curved, and made in various forms for cutting the soil, and are
so shaped and mounted, that they shall bury themselves to a considerable depth in
the soil, in order that the difference in the circle, or sweep at the outer points, and
the nearest point to the centre of the revolving tines, which is in contact with the
soil is considerable, and as the implement is drawn forward, the tines are caused to
revolve through contact with the soil, whilst the difference of speed at periphery,
and highest point of contact effectively breaks up, and cleans the soil.
Instead of obtaining the required difference in speed of the revolving tines, or
certain parts, or points of the revolving tines, with the speed of travel of the
implement, by constructing the revolving times in such a manner, so that the
point of contact at periphery, and highest point revolve at a different speed as
already described.
I can further assist the movement of the tines by gearing them to the road
wheels, by chain, or spur gearing, and cause the revolving forks, or tines, to revolve
at a different speed to travel of the implement.
Instead of obtaining the difference in speed relative to travel of implement, by
the methods above described, i can arrange the roller, or rollers, at a less angle
than at right angles, to the direction of the travel of implement, thus cansing the
soil to act obliquely on the tines, or forks, and thus increasing speed of roller.
And instead of a roller, I can use any number of sets of tines, arranged in a
single line.

COMPLETE SPECIFICATION.
Improvements in and relating to Revolving Cultivators for Steam
and other Power.
LOUIS JOHN BRIGGS of Priory Farm Stamford in the County of Lincoln 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 consists in one or more spiked rollers or pulverizers, preferably
driven from the road wheels of a suitable frame or drag and is specially adapted
for steam traction. This will be fully understood by reference to the accompanying
drawings..

page_text: I show my invention attached to an ordinary steam drag which will be ample
and sufficient to enable various modifications of more or less rollers to be
understood.
The shape & form of spikes may also be varied to suit different classes
of soil.
A are spiked rollers mounted on frame B, which rollers are worked by wheels C,
these wheels being driven by endless chains D, the driving wheels E being driven
direct from internal toothed wheels F fixed to road wheels G.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1. The construction of a rotary harrow substantially in the manner hereinbefore
described.
2. The arrangement of spiked rollers as shown and described attach to any
suitable frame.
3. The method of driving rollers or revolving harrows from road wheels as
substantially shown and described.
Dated this Twelfth day of March 1892.
LOUIS J. BRIGGS.
