PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Collecting and Distributing Oil and
other Liquids, applicable for use in Self-oiling Bearings and for
other purposes.
We, P. R. JACKSON & COMPANY LIMITED and JOSEPH SLATER LEWIS of the
Salford Rolling Mills, Manchester, Engineers, do hereby declare the nature of
this invention to be as follows:-
Our invention relates to apparatus for collecting and distributing oil and other
liquids, which apparatus is particularly suitable for use in self-oiling bearings
of the kind described in Specification No. 6791 of 1895.
The object of our invention is to construct an improved disc or "thrower"
which, when rotated on a horizontal axis so that the lower portions of the disc dip
below the surface of the liquid in a reservoir situated below the axis thereof, will
carry the liquid round with it and distribute it in the form of a spray tangential
to the circumference of the disc.
Heretofore such discs have taken the form of a flat circular plate such as
described for example with reference to a self-oiling bearing in the specification
above referred to, but we have found that such discs while working fairly satis-
factorily do not always throw up or transport sufficient liquid from the reservoir
below.
According to our present invention we construct the dise or thrower in the forni
of a plate having its margin turned in towards the centre so that a circumferential
channel is formed which is open on the side nearest the axis, said channel being
made of any suitable depth radially. In the periphery or walls of the channel at
suitable distances apart orifices are provided for a purpose hereinafter indicated.
The disc is mounted on a horizontal shaft so located with reference to the liquid
that the lower portion of the channel is submerged and filled with liquid. As the
disc is rotated the liquid in the channel is carried up and expelled by the centri-
fugal force through the orifices hereinabove mentioned the jets or spray being
approximately tangential to the circumference thereof. The liquid is therefore
distributed in the form of spray and may be caught if desired in suitable receptacles
placed to receive it. In the case of a self-oiling bearing the disc is mounted on a
shaft similar to that described for the plain disc in the specification above
mentioned.
We sometimes provide means for adjusting the size of the orifices in the
periphery of the disc. Such means for example may take the form of a strap or
Land placed round the margin of the disc either inside or outside the channel and
provided with holes corresponding to the orifices in the walls of the channel.
Means are provided for adjusting the position of the strap or band so that said
orifices may be opened or wholly or partially closed.

We, P. R. JACKSON & COMPANY LIMITED and JOSEPH SLATER LEWIS of the
Salford Rolling Mills, Manchester, 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 relates to apparatus for collecting and distributing oil and other
liquids, which apparatus is particularly suitable for use in self-oiling bearings
of the kind described in Specification No. 6791 of 1895.
The object of our invention is to construct an improved disc or "thrower"
which, when rotated on a horizontal axis so that the lower portions of the disc dip
below the surface of the liquid in a reservoir situated below the axis thereof, will
carry the liquid round with it and distribute it in the form of a spray tangential
to the circumference of the disc.
Heretofore such dises have taken the form of a flat circular plate such as
described for example with reference to a self-oiling bearing in the specification
above referred to, but we have found that such discs while working fairly satis-
factorily do not always throw up or transport sufficient liquid from the reservoir
below.
According to our present invention we construct the disc or "thrower" in the
form of a plate having a circumferential channel open at the side nearest the axis
and provided with orifices through which the oil is projected when the disc is
rotated with the channel dipping below the surface of the oil in the reservoir.
In order that our invention may be clearly understool we will proceed to
describe with reference to the accompanying drawings how we carry out the same
in practice.
Figure 1 is a side elevation partly sectional showing one of our improved oil
discs or "throwers" mounted on a shaft.
Figure 2 is a similar view illustrating a modification.
A is the shaft and B the disc the margin B₁ of which is turned in as shown s
a to form a circumferential channel. The shaft is so located with reference :
the level of the liquid indicated at C that the lower portion of the channel is sub-
merged and filled with the liquid. As the disc is rotated the liquid in the channel
is carried up and impelled by centifrugal force through the orifices B2 in the
periphery of the disc. The jets or spray will be approximately tangential to the
circumference of the disc and are or is caught in a receptacle placed to receive it.
In the case of a self-oiling bearing the disc is mounted on the shaft in a similar
manner to that described for the plain disc in our specification above mentioned.
In Figure 2 we show means for adjusting the size of the orifices in the periphery
of the disc. D is the strap or band located in a groove 1) provided at the periphery
of the circumferential channel of the disc, said strap being pierced with holes 1ª
corresponding with those in said channel. By sliding the strap round, the holes
therein may be made to coincide or not with the holes 12 in the disc so as to adjust
the size of the orifices.
The strap D may be located inside the channel if desired instead of outside
as shown.
In the drawings the discs are secured to the shaft by means of sleeves E and E¹
the former of which is keyed on the shaft being provided with a shoulder against

page_text: which the disc B is held by the sleeve E' screwed on the first sleeve. Other means
may be provided for securing the disc to the shaft if desired.
Our invention is not confined to discs with a single circumferential channel as
shown as two channels placed side by side or on opposite sides of the disc may be
employed if desired.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
1. For collecting and distributing oil and other liquids, a device consisting of
a disc or plate having at its outer circumference a channel with orifices in its walls
and with or without means for partially or entirely closing said orifices, and
operating as specified.
2. The improved discs or "throwers" constructed and operating as described
with reference to either of the figures of the accompanying drawings.
