PROVISIONAL SPECIFICATION.
Improvements in Safety Guards for Chaff-cutting Machines.
I, WILLIAM FIELDING, of 51, Heaton Lane, Stockport, in the County of Chester,
Ironmonger and Agricultural Engineer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to an improved form of safety guard for chaff-cutting
machines which is very simple in construction, readily applicable and reliable
in action.
To this end I employ in the feeding trough in front of the rollers a plate_or
board the inner end of which I suitably hinge to the shaft or axis of the top
roller to rise and fall therewith. The outer end of the said plate or board which
is also permitted to rise and fall, I form at each side with a projection adapted
to rest upon the top of the feeding trough and support the respective end and
thereby retain the plate or board at an incline.
In order to prevent the said plate or board from being unduly swung back out
of use I furnish each of the said projections with a slotted link which I secure
to the side of the trough by means of a suitable screw or bolt and nut passed
through the slot in the said links.

Improvements in Safety Guards for Chaff-cutting Machines.
I, WILLIAM FIELDING, of 51, Heaton Lane, Stockport, in the County of Chester,
Ironmonger and Agricultural 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:-
This invention relates to an improved form of safety guard for chaff-cutting
machines which is very simple in construction, readily applicable and reliable
in action.
And in order that my invention may be more fully understood I have caused
to be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is a sectional side view, Fig. 2 a plan, Fig. 3 a sectional end view
of my improved safety guard.
Fig. 1 is a side view and Fig. 2* a plan detached of a modification of my
invention.

page_text: In carrying out my invention and referring to the figures generally, I employ
in the feeding trough a in front of the feed rollers b, b¹ a plate or board e the
inner end of which I suitably hinge to the shaft or axis d of the top roller 61
so as to rise and fall therewith. The outer end of the said plate or board c
which is also permitted to rise and fall, I form at each side with a projection or
its equivalent, say a cross piece e adapted to rest upon the top of the feeding
trough and support the respective end and thereby retain the plate or board c
at an incline.
a head
In order to prevent the plate or board c from being unduly swung back out
of use or rising too high, I furnish each of the said projections or the end of
the cross piece e with a slotted link or its equivalent, say a rod f having
or nut at its free end which link or rod I respectively secure to the sides of
the trough a by means of a suitable screw or bolt and nut passing through the
slot in the said links or an eye g in which the said rods can slide.
According to a modification of my invention and referring to Figs. 1 & 2
in some cases I may bend the plate or board e crosswise and extend the sides
of the outer portion el so as to rest upon the top of the sides of the trough a.
By preference I form the board or plate c of steel and hinge the same to the
shaft or axis d of the top roller 61 by means of two arms / whereby the whole
of the guard is rendered very light and cheap.
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
In chaff-cutting machines, a safety feed guard, consisting of a board or plate c
the inner end of which is fulcrumed to the shaft or axis of the top feed roller b
and the vertical movement of which board or plate at its outer end is controlled
partly by the trough a and partly by links or their equivalent f movably con-
nected to the sides of the hopper, all substantially as set forth.
