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 to be as
follows:-
This invention relates to improvements in that class of knife cleaning machines
in which a pair of rotary rollers are employed between which the knives to be
cleaned are passed.
The object of my improvements is to provide means for the adjustment of the
top roller so as to compensate for the wear of the rollers and thus retain the same
always in proper contact with each other which renders the machine more effective
and durable.
In accomplishing this I form or furnish each end of the emery receptacle with
an upright on each of which I employ a collar or slide forming a bearing rendered
vertically adjustable thereon by means of a set screw or otherwise as will
be ound most convenient, which bearings are adapted to receive the said top
roller.
In lieu of driving the said rollers by means of spur gearing I drive the same
by means of a chain, a chain wheel being fixed upon the shaft of each roller at
the driving end in connection with a chain wheel rendered adjustable on the frame
by means of which the tension of the chain can be regulated in accordance with
the adjustment of the roller.

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 performed, to be particularly described and ascertained
in and by the following statement :-
This invention relates to improvements in that class of knife cleaning machines
in which a pair of rotary rolfers are employed between which the kuives to be
cleaned are passed.
The object of my improvements is to provide ready means for the adjustment.
of the top roller so as to compensate for the wear of the rollers and thus retain
the same always in proper contact with each other which renders the machine more
effective and durable.
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

page_text: a plan, Fig. 3 is an end view and Fig. 4 a cross section through line A-B of
Fig. 1.
a is the stand, 6 the emery receptacle secured thereto as usually, c the bottom
and d the top roller, e the handle by which the latter is turned.
In carrying out my invention and referring to the figures generally I form or
furnish each end of the emery receptacle & with an upright f,, upon each of
which I employ a collar or slide g, g, which serve as bearings for the top roller d
and are rendered vertically adjustable upon the said uprights by means of a set
screw h, h, or otherwise as will be found most convenient. By preference the said
uprights are made round in section and screwed into bosses i, i, formed on the end
of the receptacle b.
In lieu of driving the rollers c & d by means of spur gearing I drive the same
by means of a chain k, chain wheels ',, being respectively fixed at the driving
end upon the shafts of the rollers c & d in connection with a chain wheel k³
rendered adjustable on the frame or plate / forming part of the emery receptacle b
by means of which the tension of the chain k can be regulated in accordance with
the adjustment of the rollers c & d.
By preference I mount the wheel upon the stud m of a block m' rendered
adjustable in a slot l' formed in the frame or plate 1 by means of a screw n.
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 I
claim, is-
1st. In a knife cleaning machine having two rotary rollers between which the
knives to be cleaned are passed, mounting the top roller in bearings rendered
adjustable upon uprights, all substantially as and for the purpose set forth.
2nd. In a knife cleaning machine having two rotary rollers one of which is
rendered adjustable, the use of a chain and chain wheels for gearing the said
roller all substantially as and for the purpose set forth.
Dated this 13th day of January 1896.
