PROVISIONAL SPECIFICATION.
Improvements in Potato-diggers.
I, DANIEL DE Cou, of 127, Catherine Street, Philadelphia, Pennsylvania, United
States of America, Commercial Traveller, but temporarily of 76 Great Eastern Street
in the County of London, do hereby declare the nature of this invention (a communi-
cation from abroad by S. L. Allen & Co., of Philadelphia, Pennsylvania, United
States of America, Manufacturers,) to be as follows:-
This invention relates to an improved potato-digger or potato raising plough.
In carrying out the said invention I provide a beam and handles of any ordinary or
suitable construction to wbich is fixed a frame adapted to carry the various digging
appliances. These digging appliances comprise a mould board or breast to the rear
extremity of which is attached a number of short steel prongs, a suitable share being
arranged in front of the mould board.
To the rear of the frame is attached a series of laterally extending tines forming a
digging fork which serves to divide or slice the soil as it slides off the mould board.
Behind the digging fork I can arrange a supplemental rake the teeth of which are at
substantially right angles with the tines of the fork, the said rake serving to break up
the slices formed by the fork.
In operation, the digger is run directly under the row of potatoes, when the mould
board turns the furrow slice on edge, breaking it somewhat, the fork follows and the
upper tine (the foremost) cuts off about three inches of the upper edge of the slice,
spreads it out and exposes the potatoes in it to view; the other tines each take three
inches more and finish the slice. The rake, following, prevents burying in the rear of
the plough and assists in keeping the potatoes in a narrow row.
To the beam in front of the body can be attached a prong which serves to turn the
potato tops to one side so that they do not interfere with the action of the
implement.
The digger may be used either single or double, that is, it may have digging
appliances on one or both sides of the frame.

Improvements in Potato-diggers.
I, DANIEL DE COU, of 127, Catherine Street, Philadelphia, Pennsylvania, United
States of America, Commercial Traveller, but temporarily of 76 Great Eastern Street,
in the County of London, do hereby declare the nature of this invention (a communi-
cation from abroad by S. L. Allen & Co., of Philadelphia, Pennsylvania, United
States of America, Manufacturers) and in what manner the same is to be performed
to be particularly described and ascertained in and by the following statement :-
This invention relates to a potato-digger or potato raising plough, and it comprises
the improvements hereinafter described and illustrated in the accompanying drawing
which represents in perspective view a potato digging plough constructed according
to the said invention.
In carrying out the invention I provide a beam a and handles b of any ordinary or
suitable construction to which is fixed a frame c adapted to carry the various digging
appliances. These digging appliances comprise a mould board or breast d (attached
to or formed integral with the frame) to the rear extremity of which is connected a
number of short steel prongs e, e, a suitable share being arranged in front of the
would board

page_text: To the rear of the frame is attached a series of laterally extending tines f,f forming
a digging fork which serves to divide or slice the soil as it slides off the mould board.
Behind the digging fork I arrange a supplemental rake g the teeth of which are at
substantially right angles with the tines of the fork, the said rake serving to break up
the slices formed by the fork.
In operation, the digger is run directly under the row of potatoes, the mould board
turning the furrow slice on edge and breaking it somewhat. As the fork follows, the
upper tine thereof, which is also the foremost, cuts off say three inches of the upper
edge of the slice, spreads it out and exposes the potatoes in it to view; the next tine
takes, say, three inches more and so on until the whole of the slice is broken and
spread. The rake, following, prevents burying in the rear of the plough and assists
in keeping the potatoes in a narrow row.
.
To the beam in front of the body can be attached a prong h which serves to turn
the potato tops to one side so that they do not interfere with the action of the
implement.
The digger may be used either single or double, that is, it may have digging
appliances on one or both sides of the frame.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
: (1.) A potato raising plough provided with digging and spreading appliances
substantially as herein before described.
(2.) The manufacture and use of the improved potato digger hereinbefore described
and illustrated in the accompanying drawing.
