COMPLETE SPECIFICATION.
Improvements in the Manufacture of Screen, Potato, or like
Shovels.
I, Frank ParkES, Managing Director of A. and F. Parkes and Company
Limited, of Dartmouth Street, in the City of Birmingham, 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:-
This invention relates to improvements in the manufacture of shovels of a screen
construction, or of a grating type, employed in shovelling potatoes, swedes, onions
and like roots.
My invention has for its object, the simplifying and lessening the cost of the
manufacture of the said shovels, and the making of the same more efficient and
lasting in use.
Figure 1 of the accompanying drawings represents a plan of a screen or potato
shovel made according to my invention.
Figure 2 represents a longitudinal section of the same.
Figure 3 represents a transverse section of the rim of the said shovel Figure 1
upon the dotted lines A B, showing how the ends of some of the bars of the screen
pass through the upper walls of the framing, and are then rivetted, and how the top
boundary edges of the walls of the said frame are encased or beaded, so that injury
to the roots being shovelled is avoided.
Figure 4 represents upon a smaller scale a plan and Figure 5 an edge view of a
forging, from which the blank Figure 6 is made or produced by rolling or by plating out.
Figure 7 is a section on the dotted lines C D Figure 6, showing the thickness of
the metal, and also the separate languet straps.
Figure 8 represents a fashioned shovel blank, produced by stamping the blank
Figure 6 into the said shovel shape as represented.
Figure 9 is a section of Figure 8 upon the dotted lines E F.
Figure 10 represents the shaped blanks Figures 8 and 9, with the bottoms pierced
or cut out and forming a frame, across the bottom of which, wire grating rods are
disposed and rivetted, forming a complete potato shovel, as in Figures 1 and 2, and
Figure 11 is a section on the dotted lines G H Figure 10.
In carrying out the manufacture of the said shovels Figures 1 and 2, I proceed as
follows:-
I take an iron or steel forging, steel casting or billet (Figures 4 and 5) and by a
rolling process or a plating-out process I flatten or break down the same into a thin
sheet metal blank Figures 6 and 7, and then by subjecting the said blank to suitable
shaping tools, I stamp or raise the said flat blank Figures 6 and 7 into an open-
fronted dished blank Figure 8, and of the general figure and shape of the shovel to
be made.
This said body blank (Figures 8 and 9) consists of a bottom part a, outer
boundary walls a³, top edge a³, open front a', with inclined lift a', and languet straps
or socket a, a, all made solid or out of one piece of metal.
This fashioned or shaped blank Figures 8 and 9 is then operated upon and its
bottom cut out or pierced with an opening a', Figures 10 and 11, leaving a set-down
edge a³, a', with a middle support or stay a¹o, and to the said ledges a³, the
support a¹o, and the walls a², adjacent to the straps or socket a, a, the ends of the
grating or screen rods b, are rivetted, as represented in Figures 1, 2 and 3.
The boundary edging a³, of the framing Figures 10 and 11 is provided with a
cased edging e, thereby protecting roots being shovelled from injury by any sharp
or rough edges.
I wish it to be understood that I do not confine myself to the exact way of
רנס.DA

page_text: connecting the grating or screen rods represented, as the connection of them may be
varied without departing from the nature of my invention, and further, the stay or
middle support al, may be dispensed with and the screen rods affixed upon the strap
side of the body of the shovel.
I also wish it to be clearly understood that I do not limit myself to the method
of producing the thin sheet metal plate before stamping, as the same may be a plate
cut out from ordinary sheet metal and the languet straps or socket for receiving the
handle may be welded to the middle of the body part of the shovel, and further, the
said sockets may be turned up skelp-wise from. out of a single broad languet strap.
I wish it further to be understood that the shape, character or pattern of the
shovel may be varied as desired according to the market and uses of the same.
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 :-
First. In potato or screen shovels, making the frames or the pan frames of the
same by first stamping or raising thin sheet metal into a frame or pan-shaped
blank, and then removing or cutting away the middle part of the said blank,
thereby forming an open frame, which is subsequently fitted with grating bars,
substantially as described and set forth.
Secondly, In the frames. or pans of potato or screen shovels made from sheet
metal, providing or fitting the same with a rear and middle support al, substantially
as and for the purpose described and set forth.
Thirdly. The improvements in the manufacture of potato, screen and like shovels,.
by the means and in the ways substantially as described and set forth.
