IMPROVEMENTS IN CHAFF CUTTERS
Year: 1883

page_text: PROVISIONAL SPECIFICATION left by the said Samuel Edwards at the
Office of the Commissioners of Patents on the 3rd October 1883.
SAMUEL EDWARDS of Salford in the County of Lancaster Agricultural Engineer,
"IMPROVEMENTS IN CHAFF CUTTERS "
My invention relates to improvements in the construction of Chaff Cutters, and
it consists, briefly, as follows-first in the application of a safety roller attached to
the back of the top "pressure plate" or rising cover, which is also extended back
so as to completely cover the whole of the upper portion of the top feed roll;
the object of this part of my invention is to more completely protect the hands of
the operator from being caught in the feed rolls, which when only partially covered
are a source of numerous accidents-The second part of my invention consists in
the arrangement and application, of a second or auxilliary lever, to operate the
clutch motion by means of which the feed is stopped and reversed; this second
lever, is in connection with the lever motion as described in the Specification of
Patent N° 2949, 1872, which stops, reverses, and varies the length of the cut; it
is fixed to, or is a continuation of the clutch fork and is on the opposite side of
the feed box, to that on which the first or original lever is placed-The object of
this second lever is to provide a safety lever on both sides of the feed box, which
will act in unison and greatly reduce the risk of accidents.

"IMPROVEMENTS IN CHAFF CUTTERS
"
My Invention relates to improvements in the construction of Chaff Cutters, and
it consists (briefly) as follows.-
First in the application of a safety roller attached to the back of the top pressure
plate, or rising cover, which is also extended behind, so as to completely cover the
whole of the upper portion of the top feed roll; the object of this first part of my
invention. is to more completely protect the hands of the operator from being
caught in the feed rolls; which when only partially covered are a source of numerous
accidents.
The second part of my invention consists in the application of an auxiliary
lever to operate the clutch motion by means of which the feed is stopped and
reversed.
And in order that my invention may be more clearly understood I shall refer to
the annexed sheet of drawings in which the same letters of reference indicate
similar parts in any of the figures.
Fig. 1. is a front elevation of a Chaff, cutting machine, fitted with my improved
Bafety roller, and auxiliary lever.
Fig. 2. is a plan of the same machine.
Fig. 3. is a side elevation of the adjustable mouthpiece of the rising cover, and
the safety roller.
Fig. 4, shows the auxiliary lever detached from the machine
In carrying out my invention as above briefly described in the application of a
safety roller to a chaff cutting Machine, I make the top pressure plate, or rising
cover A, to extend back and completely cover the top feed roll B, and at its
hindmost extremity, I fix a safety roller C, which approximates to the length of
the feed roll. The rising cover is adjusted in position by means of a screw D,
which renders it almost an impossibility for the operator to get his hands entangled
with the feed rolls.
In the application of an auxiliary lever for stopping and reversing, I elongate
the clutch fork E, and terminate it in a handle F; this handle stands in such a
position, that in conjunction with the principal handle G, it is almost impossible
for the operator to fall against the machine, or be caught by the machinery,
without moving the handle F or G, and either reversing or stopping the machine.
The Chaff cutter illustrated in the sheet of drawings and to which I have added
my present improvements, is described in my former Specification N° 2004. 1878.
but my improvements may be added to other similar Machines.
Having now described and fully ascertained the nature of my said invention,
and the manner in which it may be carried into practice; I declare that what I
consider to be novel and original and therefore claim as the invention secured to
me by the hereinbefore in partrecited Letters Patent, is
First, In Chaff cutters, the application of the safety roller C to the rising
cover A, at the back of the feed roll B, or to any similar swivelling rising
cover or pressure plate, for the purpose, and substantially as described and
illustrated.

page_text: Second, In chaff cutters as shown in the drawings, and as described in Patent
N° 2949. 1872, the use of a second or auxiliary lever F, attached to the
clutchfork E, working in conjunction with the first lever as claimed in the
said Patent N° 2949, substantially as described and as illustrated.
In Witness whereof I the said Samuel Edwards, have hereunto set my
hand and seal this Twenty sixth day of March, in the year of Our Lord
One Thousand eight hundred and eighty four.
