Specification Accepted, 19th July, 1887.
I JAMES SALTER FARMER of the Adelphi Iron Works Salford 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 :—
My invention consists in an improved construction of machine for breaking down
or reducing cork prior to grinding the same for use as an ingredient in the
manufacture of kamptulicon corticine linoleum and various other kinds of floor cloth.
The chief features of novelty in my improved machine are the construction of the
breaking down rollers and the mode of speeding and driving the same.
In order that my Invention may be fully understood and readily carried into
effect I will proceed to describe the four accompanying Sheets of Drawings forming
part of this Specification.
Figure 1 is an end elevation Figure a plan with the upper part removed and
Figure 3 a side elevation partly a section of my improved machine for breaking
down or reducing cork. Figures 4, 5 and 6 are detail views on an enlarged scale
of some of the parts.
In Figures 1 to 3 of these views.-a represents the frame of the machine in suitable
bearings in which are mounted the shafts or axles bb shown on an enlarged scale
Figure 4 of the breaking down or reducing rollers. Each shaft 66' has a collar 62
formed or secured thereon and also has a screwed thread cut upon it; each of the
rollers is constructed or built up of two series of toothed discs or rings c and d
respectively which discs are threaded alternately upon the shafts bb and are secured
between the fixed collar 6 and a nut e screwed upon the shaft; there is a feather
key on each shaft and a corresponding keyway in each disc. The discs c see
Figure 5 are made by preference of case hardened steel and are larger in diameter
and have longer or deeper cut teeth than the discs d see Figure 6 which are
preferably made of wrought iron.
I would have it clearly understood that I do not tie myself to the shape or size
of the teeth on the discs as the same may be varied or modified but I consider
the form shown as well suited for the purposes of my Invention.

page_text: The breaking down or reducing rollers built up as described are so arranged that
when the shafts b¹ are placed in their bearings in the frame a the edge of a disc c
on the one roller comes opposite a disc d and between two discs c on the other
roller.
A hopper through which virgin or other cork or analogous material used as an
ingredient is fed into the machine is supported above the rollers.
A feature of my Invention consists in driving one toothed roller at a greater surface
speed than the other whereby a tearing in addition to a breaking crushing and cutting
action upon the cork is obtained.
Any suitable arrangement of mechanism for this purpose may be employed as for
example that shown in the Drawings which arrangement I will now describe.
g
On the shaft of one roller in this instance the shaft I secure a spur wheel
which is geared with a flanged pinion fixed on the shaft b of the other roller.
Also fixed on the shaft is a toothed wheel i geared with a flanged pinion j fixed
on a shaft which is supported and free to be rotated in bearings in a frame a¹.
The shaft is driven by a belt not shown and a pair of fast and loose pulleys 1 and m
respectively.
It will thus be seen that when the belt is on the fast pulley & motion is transmitted
from the shaft by the pinion j and wheel i to the shaft & and its roller and to the
pinion which by means of the wheel g drives the shaft 61 and the toothed roller
thereon at a slower speed than the shaft 6 and its toothed roller.
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-
1. In a machine for breaking down or reducing cork the use and application of
toothed rollers each roller being constructed or built up of two series of toothed
discs or rings arranged alternately a disc of one series being placed next a disc of
the other series substantially as and for the purposes herein described and as
illustrated by the Drawings annexed.
2. The combination with the series of toothed discs c made preferably of case
hardened steel of the alternating series of toothed discs & preferably made of wrought
iron and rather smaller in diameter and with shorter teeth than the said discs c
substantially as herein set forth for the purposes specified.
3. The mode of driving one toothed roller at a quicker surface speed than the
other toothed roller of a cork breaking machine and
4. The mechanism shown and described or any suitable equivalent thereof for
driving the said toothed rollers.
5. The improved machine constructed and arranged substantially as herein
described and as shown.
