Improvements in Journal Lubricators.
I WALTER WILLIAM SMITH of The Priory Works, High Road Lower Clapton
in the County of London, Railway Rug and Lubricator Manufacturer, 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
cotton, hair, wool, or other absorbent material is held from below close up to and
in contact with the rotating shaft to be lubricated. These pads are supported on
a frame and are supplied with lubricant by wicks or fibres of, wool, cotton or other
similar absorbent material attached to the undersides thereof, the other ends of
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 hold a pad of this description in correct position
close up to and in contact with the rotating journal, in such a manner that while the
pad is supported from below, the support is of a sufficiently resilient nature to give to
the motion of the shaft, instead of being rigidly or tightly held thereto as hereto-
fore, the pad and its support being so made that the pad can be easily and readily
fixed to the said frame in a secure manner, and can be as readily detached therefrom
and a new pad substituted as and when required.
In order that my invention and the manner in which it may be carried into
practice may be well understood, I will describe the same with reference to the
accompanying drawings in which
Figure 1 shews an end elevation of a frame and pad fitted thereto in accordance
with this invention,
Figure 2 is a plan of the frame alone,
Figure 3 is a perspective view on a smaller scale shewing the frame with the pad-
affixed thereto, the pad being broken away so as to more clearly shew the:
construction of the frame, and
Figure 4 is a detail view.
The support for the pad consists of a metallic or other frame curved to the shape
of the shaft and made in two parts each part consisting of a side piece A two end
pieces B and C and a central transverse piece D. The two parts are held together
so as to form the frame by means of transverse helical springs E wound over the end.
pieces B and C of one part, the corresponding end pieces of the other part being
placed within said helical springs E. The ends of the springs E abut against.
suitable stops or shoulders on the end pieces B B and C C or against the side
pieces A A. The end pieces B B and C C and the central transverse pieces D D of
the two parts of the frame thus lie one on the top of the other and the two sides A A
of the frame are separated by the transverse spring connections E. The sides A A
of the frame may be closed up nearer to each other according to the power of the
springs E, and when the pad is in position any small horizontal motion of the shaft
out of its true plane of rotation will be taken up by the transverse springs E on the
frame, the said springs returning the sides Å Å of the frame to their normal
position when the pressure is removed, i.e. :—when the shaft returns to its true
plane of rotation. The frame so made is supported on or attached to a vertical
spiral or other spring or springs G resting on the base of the axle box thus affording
a springy or resilient vertical support for the frame. The pad J. on such frame
will therefore give to every vertical or horizontal motion of the rotating shaft.
To fix the pad to the frame, 1 secure, in any suitable manner, a wire or other

page_text: metal rod H. to the outer edge of each longitudinal side of the pad. Each end of
the said rods H is bent or turned over in the same direction into a parallel plane, so
that said ends form hooks or catches H pointing towards each other see Figure 4
which shews a detached view of one of these rods. The longitudinal sides A A of the
frame are notched at each corner, as shewn at A' in Figure 2 and are furnished
with flanges, shoulders or other stop pieces A' on the underside thereof, see
Figures and 3.
To attach the pad to the frame the hooks H' of one of the longitudinal rods H
secured to the pad, are slipped over one of the flanges &c. A³ and into the corner
notches A of the frame. The sides A A of the frame are then nipped or pinched
together so as to compress the transverse springs E E thereon, the hooks H¹ of the
rod secured on the other longitudinal side of the pad are then slipped over the
corresponding flanges &c. A³ and into the other corner notches A. The frame is
then released from the nipping or pinching pressure, when the springs E E return"
the frame to its original position thereby stretching the pad and holding it tightly
in position on the top of the frame.
From the foregoing description it will be understood that the length of the pad
is such as 'to allow of the hooks H' on the rod H passing into the corner notches A
and being, by them prevented from passing further across the top of the frame and
that its breadth is such as to allow the pad to be held taut when the hooks H¹.
engage with the aforesaid corner notches A'. The flanges &c. A³ are to prevent
the hooks H' from passing off the edges of the frame and they may in some cases
be dispensed with.
i
Having now particularly described and ascertained the nature of my said inven-
tion, and in what' manner the same is to be performed, 1 declare that what I
claim'is':
(1) In a journal lubricator wherein the lubricant is fed by capillary attraction to
&. pad. held up to the journal, a frame curved to the shape of the journal made in
two longitudinal parts loosely kept in their relative positions by means of helical
springs on their, ends,; the frame so made being supported on a vertical; spiral or
other spring or springs resting on the base of the axle box, and being provided with
corner notches or their equivalents with which engage hooks secured to the corners
of the pads or selvedge edges thereon 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 up to the journal, the combination with a pad having hooks or catches
secured to or on its corners, of a frame supporting said pad and having notches or
the like to engage said hooks or catches and provided with transverse springs to
allow the frame to adapt itself to the horizontal motion of the rotating shaft
substantially as and for the purpose herein before set forth.
(3) In a journal lubricator wherein the lubricant is fed by capillary attraction'
to a pad on a frame held up to the journal, the method of securing the pad to the
frame by means of hooks or catches on the sides or corners of the pad engaging
with corresponding notches or recesses in the pad supporting frame substantially as
and for the purpose hereinbefore set forth.
(4) My improved means for lubricating journals substantially as described and
for the purposes stated.
