PROVISIONAL SPECIFICATION.
Improvements in Pad Frames for Journal Lubricators.
We WALTER WILLIAM SMITH, Director of Walter W. Smith & Co. Ld. and
WALTER W. SMITH & Co. LD. of The Priory Works, High Road, Lower
Clapton, in the County of London, 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 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 make the pad frames for journal lubricators of
this description in such manner that a new lubricator can be supplied to the journal
when required, in a more expeditious manner than heretofore.
The
According to this invention make the pad frame in two main parts an upper and
a lower. The lower part is supported on or attached to a vertical spiral or other
spring or springs resting on the base of the axle box in the ordinary way.
upper part carries the lubricating pad and is detachably secured to the lower part
preferably by means of two longitudinal grooves in or on the lower part with
which a tongue piece on the upper part engages or vice versú, or by means of clips
or equivalent devices for making a readily detachable connection between the
two parts.
To take out the lubricator and substitute a new one it is only necessary to
detach the upper part of the frame from the lower part, secure a new pad to said
upper part and replace it in its former position on the lower part and connect it
thereto by the clips, tongues and grooves or other detachable fastenings.

Improvements in Pad Frames for Journal Lubricators.
We WALTER WILLIAM SMITH, Director of Walter W. Smith & Co. Ld., and
WALTER W. SMITH & Co. LD. of The Priory Works, High Road, Lower
Clapton, in the County of Middlesex, 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:-

page_text: 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 make the pad frames for journal lubricators of
this description in such manner that a new lubricator can be supplied to the journal
when required, in a more expeditious manner than heretofore.
According to this invention we make the pad frame in two main parts an upper
and a lower. The lower part is supported on or attached to a vertical spiral or
other spring or springs resting on the base of the axle box in the ordinary way.
The upper part carries the lubricating pad and is detachably secured to the lower
part preferably by means of two longitudinal grooves in or on the lower part with
which a tongue piece on the upper part engages or vice versa, or by means of clips
or equivalent devices for making a readily detachable connection between the two
parts.
To take out the lubricator and substitute a new one it is only necessary to detach
the upper part of the frame from the lower part, secure a new pad to said upper
part and replace it in its former position on the lower part and connect it thereto
by the clips, tongues and grooves or other detachable fastenings.
The accompanying drawings shew a pad frame constructed in accordance with
this invention and supported on saddle springs G. Figure 1 is a side elevation
shewing the upper part of the pad frame partly drawn out from the lower part ;
Figure 2 is an elevation of same; Figures 3 and 4 are end elevations of the upper
and lower parts of the frame detached, a pad being shewn fixed in position in
Figure 3.

the upper part of the pad frame, B is the base thereof which is made of such size
as to fit into the two longitudinal grooves A1 A2 on the lower part A. An extension
wire or piece C is formed on or secured to the base B¹ and is turned up at the end
or furnished with a hook or ring C₁ at its extremity or an equivalent device may
be provided to afford a grip or purchase whereby the sliding base B' can be with-
drawn from or he passed into the grooves A¹ A³ in or on the lower part A of the
pad frame. If desired the grooves may be on the upper part and the tongue pieces
fitting same may be on the lower part of the pad frame, or clips or other readily
detachable, means of connecting the two parts of the frame together may be
adopted.
Having now particularly described and ascertained the nature of this said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:-
In a journal lubricator wherein the lubricant is fed by capillary attraction to a
pad held up to the journal, a pad frame made in two parts an upper and a lower
part removeably attached together by eans of a slide joint or by clips or other
readily detachable connectious substantially as hereinbefore described and for the
purpose stated.
