PROVISIONAL SPECIFICATION.
A New or Improved Safeguard for Chaff Cutting Machines.
We, JOHN THOMAS PROCTER, of Quay Street, Deansgate, Manchester, Beer
Retailer, and SAM THOMAS RICHARDSON, of 65, Pershore Road, Birmingham,
Warwickshire, Manufacturer, do hereby declare the nature of this invention to
be as follows:
This invention consists of the hereindescribed new or improved safety guard for
chaff cutting machines which is so designed as to effectually prevent the person who
is feeding the straw hay or the like to the revolving knives getting his fingers carried
between the feed rolls or "stars" and cut by the knives.
وو
Our said safety guard is formed of wood metal or other suitable substance and
constitutes a cover to the trough in which the straw or the like is placed, this cover
extending back from the feed rolls for a short distance that is for about the length
of a man's hand and forearm. The end of the said cover further from the feed rolls
curves upwardly.
The person who is feeding the straw or the like to the knives has to push his hand
and forearm under the said safe guard but when he has eo pushed his hand and
forearm under the safe guard as far as he can reach when standing by the machine
his fingers are prevented from reaching the knives by the back upwardly curved end
of the safeguard coming against the upper part of the man's arm above the elbow
and thus forming a stop to prevent his fingers from reaching the knives.
"
In order to euable the feed rolls or "stars to be cleared in the event of their
becoming choked in the working of the machine, the safeguard is so fixed to the
trough with a cross pin or pins or other means as to enable the safeguard to be
quickly removed and replaced. Or the safeguard may be connected to the trough
by a cross axis situated about midway between the ends of the safeguard and on
which the safeguard can rock so that the end nearer to the feed rolls or stars can
when required be pushed down into the trough to give access to the feed rolls or
stars. Or for the same purpose the fore part of the safeguard may be hinged to
the other part of the same and made to turn up when required.

COMPLETE SPECIFICATION.
A New or Improved Safeguard for Chaff Cutting Machines.
We, JOHN THOMAS PROCTER, of Quay Street, Deansgate, Manchester, Beer,
Retailer, and SAM THOMAS RICHARDSON, of 65, Pershore Road, Birmingham,
Warwickshire, Manufacturer, 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 consists of the hereindescribed new or improved safety guard for
T

page_text: chaff cutting machines which is so designed as to effectually prevent the person who
is feeding the straw hay or the like to the revolving knives getting his fingers carried
between the feed rolls or "stars" and cut by the knives.
We will describe our invention by referring to the accompanying drawing on
which
Fig. 1 shews in longitudinal sectional'elevation our invention applied to an ordinary
chaff cutting machine ;*
Fig 2 is a cross section on line XX of Fig. 1;
Fig. 3 shews the same parts as in Fig. 1 and illustrates how the said safe guard
prevents a person from getting his fingers carried between the feed rolls or stars
and cut by the knives.;
Fig. 4 shews in side elevation and Fig. 5 in sectional elevation a slightly modified
form of our invention applied to the chaff cutting machine.
The same letters of reference indicate the same or corresponding parts in all the
figures of the drawing.
A is the ordinary trough of the chaff cutting machine in which the straw or
the like is placed and B B are the usual feed rolls or stars which feed the
straw or the like in the direction shewn by the arrows in Fig. 1 to the revolving
knives C.
Our said safety guard D is formed of wood metal or other suitable substance and
constitutes a cover to the trough A in which the straw or the like is placed, this
cover D extending back from the feed rolls B' Bs for a short distanco that is for
about the length of a man's hand and forearm. The end d' of the cover D further.
from the feed rolls B' B2 curves upwardly.
The person who is feeding the straw or the like in the trough A to the knives C
has to push his hand and fore arm under the said safe guard or cover D .but when
he bas so pushed his hand and forearm undor the safe guard as far as he can reach
when standing by the machine his fingers are prevented (see Fig. 3) from reaching
the knives C by the hack upwardly curved end d' of the safe guard coming against
the upper part of the man's arm above the elbow and thus forming a stop to prevent
his fingers from reaching the kuives C.
In order to enable the feed rolls or "stars" B¹ B to be cleared in the event of
their becoming choked in the working of the machine, the safe guard D.is or may
be so fixed to the trough A as with a cross pin at d or by other suitable means as
to enable the safe guard D to be quickly removed and replaced..
Or the safe guard D may be connected to the trough A by a cross-axis at d
situated about midway between the endsid of the safe guard D.and with which
the safe guard can rock in side bearings e!e on the sides of the trough A so that
the end d nearer to the feed rolls or stars B1 B2 can when required be pushed down
into the trough as shewn by dotted lines in Fig. 1 to give access to the feed rolls
or stars B' B³ Or for the same purpose the fore part of the safe-guard may be
hinged to the main part D of the same as shewn in Fig. 5 and made to turn up
when required as shewn by the dotted lines in this figure.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:-
1. In a chaff cutting machine the employment of a safe-guard made as a cover to
the front part of the trough immediately behind the feed rolls or "stars" and
extending far enough along the trough to prevent a man's fingers from being
drawn into the feed rolls under the said cover, substantially as hereinbefore
described.
2. In a chaff cutting machine the employment of the safe-guard D'made as a
cover to the front part of the trough immediately behind the feed rolls' or "stars"
and extending far enough along the trough to prevent a man's fingers from being
drawn into the feed rolls under the said cover which is carried by a cross axis on
the trough.so that the front of the safeguard can be pressed down into the trough

page_text: to give access to the feed rolls, substantially as hereinbefore described and'illustrated
by the accompanying drawing.
3. In a chaff cutting machine the employment of the safe-guard D made as a.
cover to the front part of the trough immediately behind the feed rolls or "stars"
and extending far enough along the trough to prevent a man's fingers from being
drawn into the feed rolls under the said cover which has the front part d³ nearer
to the feed rolls hinged to the main part of the cover D to turn up and give access
to the feed rolls, substantially as hereinbefore described and illustrated by the
accompanying drawing.
