Improved Turnip Lifting Machine.
I, JOHN ROBERTSON, of Conon, North Britain, Implement Maker, do hereby
declare the nature of this invention to be as follows: -
This invention relates to an improved turnip lifting machine.
The machine consists of a single beam carried on four wheels, two wheels in
front and two wheels behind. The front wheels are swivelled and are guided
by a handle from the rear of machine when turning at the end of drills.
In rear of front wheels there is hanging from the beam a fork and to the bottom
of same are bolted two long horns or dividers for lifting up crops and turnips that
may be lying side ways. In rear of that are bolted two strips of iron and rivetted
to top of them is a knife of Ụ shape; and on the right hand side there is a bulk-
ing on one of the strips and through this bulking is a small pin and collar and on
the top of the collar is a four pronged revolving knife. It is rivetted on to the
collar and held in position by same collar and it is connected to beam by a self
adjusting shaft and that adjusting shaft is driven by a bevel wheel and pinion
attached to the beam. The driving power comes from the hind wheels and is trans-
mitted to the four pronged knife shaft by a chain, the same as is used on binders
and such like.

Improved Turnip Lifting Machine.
I, JOHN ROBERTSON, of Conon, North Britain, Implement Maker, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to an improved turnip lifting machine.
The machine consists of a single beam carried on four wheels, two wheels in
front and two wheels behind, the rear wheels being preferably constructed of
malleable or cast iron, so formed as to always have power to revolve the topping
knife, having bars across their faces to grip the ground and a double rim in the
centre of same.
The front wheels are swivelled and are guided by a handle from the rear of
machine when turning at the end of drills. In rear of front wheels there is hang-
ing from a beam a fork and to the bottom of same are bolted two long horns or
dividers for lifting up crops and turnips that may be lying side ways. In rear

page_text: of that are bolted two strips of iron and rivetted to top of them is a knife of
Ushape and on the right hand side there is a bulking on one of the strips and
through this bulking is a small pin and collar and on the top of the collar is a
four pronged revolving knife. It is rivetted on to the collar and held in position
by same collar and it is connected to beam by a self adjusting shaft and that
adjusting shaft is driven by a bevel wheel and pinion attached to the beam. The
driving power comes from the hind wheels and is transmitted to the four pronged
knife shaft by a chain the same as is used on binders and the like.
In the accompanying drawing which represents a perspective view of a turnip
lifting machine constructed in accordance with my invention A are the front
wheels which are swivelled and guided by the handle B. C is the fork hanging
from the beam cat the lower end of which are situated the extensions c¹² bear-
ing the dividers D. E is the U shaped knife secured to the rear ends of the
extensions . F is the four pronged revolving knife which is mounted upon
the bracket d, provided with a collar or socket within which is free to slide a
square shaped spindle or shaft so that when the knives E and F, which always
bear the same relative positions to each other, are adjusted by raising or lowering
the fork C the knife F is always rotated. The spindle or shaft is rotated by
means of the bevel wheel J engaging with the bevel wheel J which is driven from
the axle of the rear carrying wheels by the bands or chains and wheels j¹. In
order to allow the spindle to adjust itself and keep the pinions in proper mesh with
each other, no matter at what angle the shaft may be placed I provide what I may
term a tumbling box K, consisting of a casting pivotted upon the shaft carrying
the bevel wheel J as shewn and within which casting the bevel wheel Jand
shaft are mounted.
The extensions c² are hinged at G and connected together by a bow H so that
the knives are free to rise and fall and thus adapt themselves to cut the tops off
turnips of different sizes and which may be at different levels.
Lis a lever by which the handles of the machine can be adjusted. The turnips
after being topped and tailed are lifted out of the ground by the rear part of the
tailing knife and left in rows in the same way as they grew; or by applying a
double rod to the said knife they may thrown to one side. The machine may be
made to treat one row or it may be made double to treat two rows.
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 general arrangement, construction and combination of parts constituting
my improved turnip lifting machine, substantially as hereinbefore described and
shewn in the accompanying drawings.
2. The arrangement and construction of revolving knife F and the arrangement
of the gearing for operating the same, substantially as and for the purpose herein-
before described and shewn in the accompanying drawings.
3. The arrangement and construction of the hanging fork C to which the dividers
are secured, substantially as hereinbefore described and shewn in the accompany-
ing drawings.
4. The arrangement and construction of the knife E secured at the rear of exten-
sions c¹² of the fork C, substantially as hereinbefore described and shewn.
