page_text: Improvements in Journal Lubricators.
HENRY EDWARD LESTER and THOMAS PERKINS, both of Royal Albert Docks
London Shipwrights and Engineers do hereby declare the nature of this invention
to be as follows:--
This invention relates to that class of journal lubricators wherein a pad of
cotton, hair, wool or other absorbent material is held from above or from below
close to and in contact with the rotating shaft to be lubricated. These pads are
attached to a frame and are supplied with lubricant by wicks or fibres of wool,
cotton or other similar absorbent material attached to the backs thereof, the
other ends of the said wicks or fibres dipping into an oil box or other receptacle
and the liquid lubricant thus supplied to the pad and spread over its surface by
capillary attraction.
The object of this invention is to make the said oil box or other receptacle
supplying the wicks or fibres, adjustable to any height in order to make the
feeding of the lubricant through the said wicks or fibres, faster or slower as may
be desirable.
According to this invention we fix to the plummer block, hanger, or axle box,
one or more upright pieces of iron or other rigid material upon which we place the
oil-box or other receptacle into which the ends of the wicks or fibres dip. This
oil-box is kept in position by
of
means
metal bands which are
attached to the oil box and slide over the said uprights. The height of the said
oil box is adjusted on the uprights by means of thumbscrews or other similar
contrivance going through the said metal bands and clamping them against the
said uprights at any desired height.

We, HENRY EDWARD LESTER and THOMAS PERKINS, both of the Royal Albert
Docks, in the Administrative County of London, Shipwrights and 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:
This invention relates to that class of journal lubricators wherein a pad of
5 cotton, hair, wool or other absorbent material is held close to and in contact with

page_text: the rotating shaft to be lubricated. These pads are attached to frames and are
supplied with lubricant by wicks or fibres of wool, cotton or other similar absorbent
material each secured at one end to the back of the pad, the other end dipping
into an oil box or other receptacle, the liquid lubricant being thus supplied to
the pad and spread over its surface by capillary attraction.
The object of this invention is to provide journal lubricators of the kind herein-
before described with means whereby the oil boxes or receptacles can be adjusted
at varying distances from the shaft the operative lengths of the feeding wicks
or fibres being thereby increased or diminished so that the quantity of oil or other
liquid lubricant fed by said wicks or fibres can in this manner be regulated as
desired.
In the accompanying drawings we have shown our invention as applied to n
tunnel shaft bearing. Fig. 1 is a perspective view, part of the plummer block being
broken away to more clearly show the invention, and Fig. 2 is a central vertical
section of same.
The pad A. is secured on the underside of a box frame B which is made some-
what smaller than the grease box C on the top of the plummer block. The
bottom of the frame B is of a skeleton formation or is provided with perforations
or holes such as 61 through which the wicks or fibres a secured to the back of
the pad are passed as shown in Fig. 1.
The oil box or other receptacle D is provided with two metal loops d having
screw threaded holes therein through which works a thumb or set screw ¹.
EE are two upright pieces or standards of metal or other rigid material fitting
the loops on the back of the oil box or other receptacle D, and if required
furnished with countersunk holes to receive the ends of the thumb or set screws d'
These two standards E are secured to the plummer block as shown, or they may
be secured to any other fixed part. The method of adjustment of the oil box or
receptacle D on the standards E will be understood without further explanation ;
the dotted lines in Fig. 2 show one position in which the box or receptacle D may
be adjusted.
It will be obvious that one, two, three or other number of standards E may be
used as required and that they may be arranged vertically as shown or horizontally
or inclined in any direction the box D being then so fitted that when adiusted its
bottom is always horizontal to prevent the oil from running out. It will also be
obvious that the fixing of the oil box or receptacle in the adjusted position may
be effected by any suitable contrivance other than the loops and screws described
and shown; also that the invention may be applied to other journal bearings and
that the pad may be placed to one side, underneath or on any other available
part of the shaft. These are all details of construction not affecting the general
principle of the invention which is to provide an adjustable oil box or other
receptacle for this kind of lubricator so as to effect a quick or a slow feed of oil
as may be required.
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. In a journal lubricator wherein the lubricant is fed by capillary attraction
to a pad held to the journal, an oil box, or other receptacle into which the ends
of the feeding wicks or fibres dip, adjustable at varying distances from the shaft
substantially as hereinbefore described and for the purposes stated.
2. In a journal lubricator wherein the lubricant is fed by capillary attraction to
a pad held to the journal, an oil box, ce other receptacle into which the ends of
the feeding wicks or fibres dip, adjustable on or over a standard or standards
secured to the journal hearing or to any other fixed part substantially as herein-
before described with reference to the accompanying drawings and for the purposes
stated.

page_text: 3. Means such as hereinbefore described for regulating the rate of supply of
oil to a pad on a shaft, consisting of an adjustable oil box or receptacle receiving
the ends of the wicks or fibres feeding said pad substantially as set forth.
