PROVISIONAL SPECIFICATION.
Improvements in Hay Making Machines.
:
I JOHN EDWARD SHARMAN PERKINS, of Queen Street Peterborough,
Agricultural Engineer do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in hay-making machines and is specially
applicable to that class of machine in which the hay is moved by a series of forks
actuated by a crank shaft. Part of it is however applicable to machines with
revolving forks.
At the back of the forks I fix a screen in a vertical or inclined position, and so
placed as to prevent, the hay which has been turned being blown forward by the
wind on to the machine so as to interfere with its working.
In this screen sometimes provide slots or gaps, through which the fork arms or
fork teeth may pass.
In that class of machines in which the fork teeth are carried on arms actuated
by a crank shaft I connect the arm which carries the forks to the frame of the
machine by a spring in addition to, or in stead of, by a jointed arm.
Dated this 9th day of March 1892.

COMPLETE SPECIFICATION.
Improvements in Hay Making Machines.
JOHN EDWARD SHARMAN PERKINS of Peterborough, in the County of
Northampton, 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:-
My invention relates to improvements in hay making machines, and is specially
applicable to that class of machine, in which the hay is moved by a series of
forks actuated by a crank shaft, part of it is however applicable to machines with
revolving forks.
At the back of the forks, I fix a screen in a vertical or inclined position, and so
placed as to prevent the hay which has been turned, being blown forward by the
wind on to the machine, so as to interfere with its working. In this screen I some-
times provide slots or gaps, through which, the fork arms or fork teeth may pass.
In that class of machines, in which the fork teeth are carried on arms actuated
by a crank shaft-1 connect the arm which carries the forks to the frame of the
machine by a spring in addition to or instead of by a jointed arm.

page_text: allow the passage of the forks, thus allowing the screen to be brought nearer to the
machine.
Fig. 7, is an elevation of a machine with rotary action, in which similar gaps
are provided in the screen at C, to allow the passage of the forks, through the
screen.
Figs. 8, 9, 10, 11 and 12 show methods of connecting the fork arms, in a crank
action hay making machine, to the frame of the machine. In 'Figs. 8 and 9 the
fork arm (D) is attached to the link (F) by a spring (E) in addition to the usual
joint at (G).
In Figs. 10 and 11, the joint (G) is dispensed with and the attachment is by the
spring (E) only.
In Fig. (12) the spring fork (H) is continued and attached to the machine at K.
Having now particularly described and ascertained the nature of
my inven-
tion and in what manner the same is to be performed, I declare that what I
claim is,―
"
1st. In a haymaking machine with rotary action, the employment of a screen or
windguard, and fixed behind the machine substantially as described.
2nd. In a haymaking machine with crank action, the employment of a screen or
windguard fixed behind the machine substantially as described.
3rd. In a haymaking machine with crank action the attachment of the forks to
the frame of the machine by springs, in addition to or instead of by jointed arms,
substantially as described.
