PROVISIONAL SPECIFICATION.
Improvements in Seat Stays or Standards for Mowing, Reaping,
and other Machines.
I, SAMUEL BRASSINGTON BAMFORD, of the Firm of Bamford & Sons, Leighton
Iron Works, Uttoxeter, in the County of Stafford, Engineer, do hereby declare the
nature of this invention to be as follows:-
My invention relates to spring seat stays for mowing, reaping and other machines
on travelling wheels.
The seats used on such machines are frequently supported on a rigid stay, made.
of round iron with a square shank at the lower end which in the case of a mower
or reaper can be slipped in either of two square holes on the mower platform
according as to whether the machine is to be used for mowing or reaping.
According to my invention I propose to use a flat stay which, at its lower end,
is hollowed or rounded a little to stiffen it, whilst its lower extremity is folded in
such a way that its two sides meet, or nearly meet, each other. This folded part
is then hammered to form a taper end of square section.
As there is very little forging required, these seat stays are easily made out of flat
steel, whilst the curving or rounding of the lower end gives sufficient stiffness to
prevent bending, or giving way when a man is riding on the seat.
I can stiffen the seat stay any distance up according to the length of the stay and
give more or less spring as required.
-
I sometimes dispense with the square end, using a hollowed or rounded end only
which may be slightly tapered and adapted to fit into holes of similar shape.

Improvements in Seat Stays or Standards for Mowing, Reaping,
and other Machines.
I, SAMUEL BRASSINGTON BAMFORD, of the Firm of Bamford & Sons, Leighton
Iron Works, Uttoxeter, in the County of Stafford, Engineer, 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:-

page_text: made of round iron with a square shank at the lower end which in the case of a
mower or reaper can be slipped in either of two square holes on the mower plat-
form according as to whether the machine is to be used for mowing or reaping.
The object of my invention is to provide a seat stay which is more flexible than
those of the kind herein before referred to and to this end I propose to use a flat
▪stay which, at its lower end, is hollowed,, rounded or arched slightly to stiffen it,
whilst its lower extremity is folded in such a way that its two sides meet, or nearly
meet, each other. This folded part is then hammered to form a taper end of square
section.
My invention will be readily understood by reference to the accompanying
drawing, in which :-
Figure 1 is a side view of my improved, seat stay;
Figure 2 is an underside view of the same; and,
Figure 3 is a section on the line 3-3 Figure 1.
a is the flat steel plate of which the stay or standard is formed, the upper end
of which plate is bent to any suitable shape or angle to adapt it to the seat which
is to be affixed to it.
In forming the lower end b of the stay or standard I arch a portion of the length
of the said plate say, from the point c to the end d as shewn in Figure 3, and I'
then hammer or force together the two edges of a part of this portion c, d say from
the point e to the end d, this part e, d being made square to fit the socket for, which
it is intended and being bent to the desired angle relatively with the main portion a
as will be clearly understood by reference to the drawing..
If the material of which the stay is made is not of sufficient thickness to permit,
of forming the square end of the desired size a wedge shaped piece of metal of the,
required dimensions can be inserted between the turned in edges of the portion e, d
the whole being hammered or swaged together to form a solid end.
A seat standard or stay. constructed as herein before described, possesses great:
elasticity whilst the curving or arching of the lower end gives sufficient stiffness
to prevent bending of the stay under the weight of a person riding, upon the seat.
It will be obvious that the arched portion of the stay instead of extending to the
point c.only may extend over, a greater or lesser distance along the same according
to the length of the stay and to, the extent of the flexibility required.
Sometimes instead of making the end 6 square I'hollow out or round, the said end
or make it slightly taper, the hole in which the said end is to be fitted being of
similar.shape.
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:-
The manufacture and use of seat stays or supports substantially as hereinbefore
described and illustrated in the accompanying drawing.
