PROVISIONAL SPECIFICATION.
Improvements in Knife Oleaning Machines.
1, HENKY LIEBERT, of Ivy Villa, Victoria Park, Manchester, in the County of
Lancaster, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to that class of knife cleaning machines in which a pair
of rotary rollers are employed between which the knives to be cleaned are passed
and which rollers are driven by means of a chain and chain wheels.
In order to compensate for the wear of the said rollers one of them is rendered
adjustable and also the wheel by which motion is imparted to the said chain in
order to keep the latter at the required tension.
The object of my invention is to provide means whereby the tightening of the
said chain is effected automatically.
To this end I form one of the bearings of the roller which is rendered adjustable
at the back with a nose, incline or cam face, adapted to bear against a projection
or block arranged on the axis of the chain which imparts motion to the said chain
and which is adapted to slide in the frame of the machine. It will thus be readily
understood that when lowering the said roller the said nose, incline or cam face
pressing against the said projection or block causes the respective chain wheel to
slide away from the rollers in distance sufficient to give the required tension.

Improvements in Knife Cleaning Machines.
I, HENRY LIEBERT, of Ivy Villa, Victoria Park, Manchester, in the County of
Lancaster, Engineer, do hereby declare the nature of this invention and in what
manner the same is to be perfornied, to be particularly described and ascertained in
and by the following statement :-
This invention relates to that class of knife cleaning machines in which a pair
of rotary rollers are employed between which the knives to be cleaned are passed
and which rollers are driven by means of a chain and chain wheels.
In order to compensate for the wear of the said rollers one of them is rendered
adjustable and also the wheel, which keeps the said chain at the required tension.
The object of my invention is to provide means whereby the tightening of the
said chain is effected automatically.
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 side view partly in section of a roller knife cleaning machine provided
with my improvements, the stand being shown broken off. Fig. 2 is a plau, Fig. 3
an end view and Fig. 4 a cross section through line A-B of Fig. 1.

page_text: a being the stand, 6 the emery receptacle secured thereto, c the bottom and d the
top roller, e the handle by which the rollers are turned,,', the chain wheels,
the chain by which the rollers & d are geared up.
In carrying out my invention and referring to the figures generally, I form the
back of the adjustable roller bearing d'; at the driving end of the machine, with a
nose, incline or cam face h, see more particularly Fig. 3, adapted to bear against
a projection or block i formed on the axis or stud k of the chain wheel f which
latter imparts tension to the chain g the block i being adapted to slide in a slot 7 in
the end of the frame of the machine. The part of the said block outside the frame
is also formed with an incline or bevel corresponding with that on the bearing d
so as to insure easy adjustment of the block and wheel i and f
It will thus be readily understood that when lowering the roller d the nose,
incline or cam face h pressing against the projection or block i causes the chain
wheel to slide away from the rollers c & d in distance sufficient to give the
chain g required tension.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what 1
claim, is--
In roller knife cleaning machines of the class hereinbefore specified, forming
the axis or stud of the tension chain wheel with a block or projection i arranged
in contact with a nose, incline, bevel or the like formed upon the bearing of the
adjustable roller, in such a manner that when the latter is lowered the said blook
or projection is caused to slide laterally and the wheel thereon tensions the
chain as required, all substantially as set forth.
