We, JOHN ARTHUR YEADON, of 4 Albion Place, and ROBERT MIDDLETON, of
Sheepscar Foundry, Meanwood Road, both of Leeds, in the County of York, and
both Engineers, do hereby declare the nature of this invention to be as follows:-
To minimise friction one of the best plans of running a Disintegrator with two
revolving cages is to arrange a turned horizontal fixed shaft on suitable standards,
and then mount the revolving cages thereon-by this means the surface speeds in the
bearings are kept as low as possible. One objection to this plan has been the difficulty
of properly oiling them, because, except when standing, no approach can be had to
any oil holes in the revolving parts. Attempts have been made to get over this
difficulty by boring holes in the centres of the fixed shaft and through this channel
to lead oil directly into the bearings by means of holes actually in contact with such
bearings. There has been, however, a tendency for the oil to choke up these holes.
Moreover where central chambers are only partially full of oil there has been a
tendency for the oil by reason of its centrifugal force to fly into the remotest parts
away from the shaft thus leaving the shafts dry although the desired oil may be
quite near.
The object of our invention is to find a positive remedy for these defects and make
the oiling arrangements more simple and reliable and specially easy to clean with
certainty.
We make a central chamber for holding oil as is usual-by arranging recesses in
the boss of each cage; we then make a hole up the fixed shaft, preferably through the
axis, far enough to get clear of all mountings, and finally arrange transverse holes-
all in a line (1) through the boss on one side tapping the oil in the recessed space-
(2) through the central fixed shaft tapping the central oil hole on the way, and (3)
through the other side of the boss. By this means any clagged oil may be very readily
dislodged by thrusting a rod or wire up through the hole in the central shaft and also,
when standing, through the three holes when brought into line. The two holes in
the boss are fitted and made good with caps which need only he unscrewed for cleaning
nurposes

page_text: We use an oil cup or cistern placed in an elevated position above the shaft so that
the feed shall be under a little pressure due to the head of the oil. Or this may be
arranged to be fairly heavy and taps may be placed so as to put on the full pressure
only at intervals-or to throttle it down to a more constant requirement. The oil cups
are so connected as to properly convey.the pressure of the oil to the hole in the central
shaft. The bearings of the revolving bosses of the cages are made of such a length
that each bearing is capable of taking the oil it requires from the central recess, as it
were, by leakage.
The arrangement here described will permit the fixed shaft to be moved round into
another position if wear and tear makes it desirable.
Where an intermittent feed is sufficient-hand oil pumps may be arranged to supply
the necessary pressure for the proper lubrication.
We prefer to arrange our disintegrators in such a way that the fixed shaft is firmly
held on one base-plate made solid with the vertical standards-and in these standards
we make oil pockets into which the waste oil can run, and from thence afterwards be
drawn off.

We, JOHN ARTHUR YEADON, of 4 Albion Place, and ROBERT MIDDLETON, of
Sheepscar Foundry, Meanwood Road, both of Leeds in the county of York, and
both engineers, 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:-
Our invention is designed to improve the effective working of disintegrators such
as those described in the specifications of Letters Patent granted to Thomas Carr
numbered respectively 778 of 1859, 3235 of 1868 and 1417 of 1873 and relates more
particularly to the lubricating of such machines.
To minimise friction one of the best plans of running a Disintegrator with two
revolving cages is to arrange a turned horizontal fixed shaft on suitable standards and
then mount the revolving cages thereon ;-by this means the surface speeds in the
bearings are kept as slow as possible. One objection to this plan has been the difficulty
of properly oiling them, because, except when standing, no approach can be got to any
oil-boles in the revolving parts. Attempts have been made to get over this difficulty
by boring holes in the centres of the fixed shaft and through these channels to lead
oil directly into the bearings by means of holes actually in contact with such
bearings. There has been however a tendency for the oil to choke up these holes.
Moreover where central chambers are only partially full of oil there has been a
tendency for the oil by reason of its centrifugal-force to fly into the remotest
parts away from the shaft thus leaving the bearings dry, although the desired oil
may be quite near.
The object of our invention is to arrange a positive remedy for these defects and
make the oiling arrangements more simple and reliable and, specially, easy to clean
with certainty.
In order to fully describe our invention we have annexed a drawing on which fig. 1
shows an end elevation of a disintegrator mounted as described; fig. 2 is a sectional
elevation of the same; and fig. 3 is a plan of the base plate with the steel or
wrought iron shaft fixed across it. The same letters refer to the same parts in all the
figures.
In fig. 2, A, and A¹ are the two bosses (which carry the two disintegrator cages)
which revolve on the fixed shaft B, B; whilst C, C, are the belt pulleys for actuating
them.
We make central chambers D, D, for holding oil as is usual, by arranging recesses
in the boss of each cage; we then make a hole up the fixed shaft B at each end,
preferably thro' the axis, far enough to get clear of all mountings; and then finally
arrange transverse holes at B¹, and B. These latter holes run in a line,-(1) thro'
the boss on one side tapping the oil in the recessed space, (2) thro' the central fixed
shaft B tapping the central oil-hole on the way, and (3) through the other side of
the boss. By this means any clagged oil may be very easily dislodged by thrusting a
-

page_text: rod or wire up through the hole in the central shaft and also, when standing, thro'
the three holes when brought into line. The two holes in the boss are fitted in each
case with caps-sce E, E, E, E, which need only be unscrewed for cleaning-out
purposes.
We further use an oil cup F, or cistern, or pipe, placed in an elevated position above
the shaft so that the feed shall be under a little pressure, due to the head of the oil.
Or, this head may be arranged to be fairly heavy and taps, as at G. may be placed so
as to put on the full pressure only at intervals or to throttle it down to a more constant
requirement. The oil cups, say one on each side, have coupling pipes arranged for
easy disconnection and they convey the oil and its pressure through the central hole
in the shaft B. and thence through the transverse holes into the central recesses. The
bearings of each revolving boss are arranged so as to take their oil from their central
recess as it were-by leakage. At any rate pressure can be put on so as to force
the oil through into every part of the bearings. Where the two bosses abut against
one another, sideways, at the centre, we prefer to arrange a ring which runs, or
stands, loose on the shaft between them. This is not shown on the drawing.
The arrangements here described will permit the "fixed" shaft to be moved by a
workınan round into another position if wear and tear makes it desirable.
Where an intermittent pressure-feed of the oil is sufficient hand pumps, or other
such appliances, may be resorted to for giving the proper lubrication.
We prefer for the sake of general efficiency to arrange our disintegrators in such a
way that the central "fixed" (so called) shaft B, B, is firmly mounted on one base-
plate. W, cast solid with the vertical standards Y, Y, and in these latter we make
pockets, H, H, into which any surplus oil can run, and afterwards be drawn off through
the holes at J, J.
Having no particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to he performed we declare that what we
claim is
1. The improved lubricating arrangements, for disintegrators running on a fixed
shaft, whereby a reliable mode of lubricating, and cleaning the oil channels, is obtained,
substantially as described herein and shown on the drawing.
2. The general arrangement of the whole disintegrator, with its improved lubricating
arrangements, mounted on two standards cast in one solid piece with the base plate
with pockets for catching surplus oil escaping from the "fixed" shaft, substantially as
described herein and shown on the drawing, with the object and for the purpose set
forth.
