A Combined Axle or Shaft and Lubricant Reservoir.
WILLIAM WALKER HOOD. Mining Engineer, Llwynypia, Glam., and GEORGE
TUCKER JONES, 23, Sherwood Place, Llwynypia, Glam., Engineer do hereby
declare the nature of this invention to be as follows:
This invention relates to,-a combined axle or shaft and lubricant reservoir, for
the lubricating, automatically or otherwise, of its bearings or journals.
It consists in making a tube serve as an axle or shaft so that the bore of the
same can be utilized as a reservoir for a lubricant necessary for the lubrication of
its bearings or journals by means of mechanical fittings therein contained, which
are to be actuated by suitable attachments fitted on one or both ends of same, which
will be for automatic or hand-feed.
Fig. (1) is a drawing in section of the invention as applied in the construction
of a colliery tram axle, with the arrangement, for the automatic working of the
lubricating pistons (LP) by means of the toothed working disc (T W D) and
appertenances.
The spaces in the axle for the necessary lubricant are those shown in the tube
between the combination plug (CP) and the terminal plug (T P), respectively,
and their lubricating pistons (LP).
Fig. (2) represents part of one end of tube (T) in Fig. 1., showing the
combination plug slightly modified for band feed. It will not always be possible
or convenient to use the axle or shaft fitted with the toothed working disc (TWD)
and appertenances, therefore it is necessary to fit the axle thus, for actuating the
pistons (LP) by hand.
Fig. (3) gives plan of position of set pin (SP) in (Fig. 1.) showing the split pin
necessary for preventing same from unscrewing, recessed in a groove formed across
the set pin hole in collar (C).
Fig. (4) is an enlarged cross section of tube and screw in Fig. 1. showing face
view of pistons (LP), valve in same, and position of screw hole, which is
considerably out of centre,-this is necessary for the self guiding of pistons (L P)
when the screw (S) is caused to revolve.
Fig. (5) is an enlarged section of part of tube (T) in Fig. 1., with outlet
holes (OH) shown fitted with a check valve (CV) chiefly necessary for use when
a liquid lubricant is used, as it will close when the pistons are not working, thereby
making the loss of lubricant impossible.
The accompanying drawings represent the invention as applied in the
construction of a colliery train-axle.
Fig. is a section of the tube containing the lubricating pistons (LP) which
are caused to travel in opposite directions by means of a combined right and left
hand threaded screw (S), for the purpose of forcing the lubricant through the
outlet holes (OH), which are provided with check valves (CV) which may be
made of elastic material for preventing the loss of lubricant when the same is not
required.
In this (Fig. 1) is the toothed working disc (T W D) for the automatic working
of the lubricating pistons (LP); this toothed working disc is connected with the
screw (S) by an intervening toothed shank (TS) formed so as to engage with a
similarly toothed key (TK) which slides on the squared part of the end of the

page_text: screw (S) which is provided with a combination plug (CP) part of which is made
of joint making material, which is built up so as to serve as a joint on inside face
of tube and on the circumference of part of the screw end; it also forins the stop
block or support for a suitable spring (RS) necessary for keeping the toothed
key (TK) well up to the toothed shank (TS); this arrangement is intended to
obviate the possibility of the lubricating pistons (LP) travelling in a contrary
direction to that for lubricating. If it happens that the toothed working
disc's (TWD) were to come in contact, when the tram travels, with anything
other than that provided for the right working of same. This is to be in the form
of an arm, or lever arranged so that the toothed working disc (T W D) will
engage with a suitable rack or blade provided at the end of the arm, or lever, and
hence be worked in the right direction for lubricating.
After
This arm or lever is to be held at a suitable angle to the road on which the
tran travels, in a position selected by the users, and to be supported by weights,
or springs, of sufficient weight or strength to keep it at the same angle, so as to
cause the toothed working discs (T W D) to revolve when the tram passes.
successive journeys, thus automatically actuated, the lubricating pistons (LP) will
have travelled their course in the tube (T) riz.-up to the outlet holes (OH) which
result in the toothed working disc remaining rigid when next in contact with the
rack or blade of arm or lever, and as the screw (S) is made strong enough to
resist the effect of the weights or springs used with the arin or lever, the result
will be that the arm or lever, which is pivoted, will yield radially, to the toothed
working disc (T W D) when the tram passes, untill the grip between the disc and
rack or blade is lost, resulting in the sudden return of the arm, or lever, and
simultaniously giving an alarm which serves to shows that the axle or shaft wants
refilling with lubricant. This alarm is produced by a bell or gong, or other
suitable signalling aparatus provided in connection with the arm or lever..
hand-feed alone can be used, it is only necessary to extend the screw in length
towards the end of tube (T) and to make the combination plug (CP) of a suitable
design to serve the purpose of a fixed plug necessary for holding the screw (S) in
true working position in tube (T). Fig. 2 shows the combination plug CP) in
the end of tube for hand feed. Fig. 3 gives plan of position of set pin (SP)
necessary for holding toothed shank (TS) or combination plug (CP) in position.
The set pin is here shown conviently screwed through a collar (C) in most cases a
necessary adjunct to an axle or shaft, and as the same are liable to great jerks
when at work, which would cause the loss of screws, it is deemed necessary to
provide against the possibility of such loss, by making a groove across the screw
hole for the introduction of a split pin (S P¹).
'
Where
By this arrangement the set pin (S P) (more than one if necessary,) is screwed
down so as to be within the outside dia., of the collar, so as to be clear from
the danger of being knocked about. (RH) is the recharging hole.
When a new
supply of lubricant is necessary, a connection by means of a suitable tube is made
between this hole and the vessel containing the lubricant, the lubricant is then
forced in so as to fill the space between the pistons, which are at their extreme
travelling distances (wa-as far as the outlet holes (OH) this being done, the
connection is withdrawn, and the recharging hole (RH) is stopped by means of a
plug, or other suitable stopper, so that when the pistons are worked back to the
centre of the axle or shaft, it will be possible for the lubricant to pass through the
back pressure valves (B PV) provided in the lubricating pistons (LP). Fig. 4 is
an enlarged cross section of tube, and screw, showing a face view of piston, valve in
same, and the position of screw hole, which is considerably out of centre. By this
arrangement the pistons will guide themselves in the circular tube, thereby
dispencing with the necessity for providing a groove in the tube, which would
weaken it, and make it difficult to produce joint inaking buckets (B) and rings for
the lubricating pistons (LP) equal to those necessary for a circular tube; (this
also applies to a tube other than a circular bore). (L) is a liner between toothed
shank (TS) and part of tube. (G E) is the grip end of screw (S) for hand working

page_text: by means of a key, which may have 3, 4, or any other number of squares. (TP) is
a terminal plug. (JR) joint ring. (C) cotter. (W) washer or loose collar.
A collar with screws such as those shown at the feed ends will serve the same
purpose.
Fig. 5 is a section of part of tube with outlet hole (O II) shown enlarged. The
check valve (CV) contains a slit which will open when the pressure is on from
inside tube (see dotted lines), so as to allow the lubricant to pass out. This valve
being flexible, will close when the pressure is stopped; it may be conviently
held in position by a washer, screwed or otherwise fastened in the outlet hole.
Very few modifications in the construction of the principle parts described in this
Specification, is necessary for the application of this method of lubrication to other
vehicles and working systems with which axies or shafts are used.

WILLIAM WALKER HOOD, Mining Engineer, Llwynypia, Glam. and GEORGE
TUCKER JONES, 23, Sherwood Place, Llwynypia, Glam., Engineer, 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 a combined axle or shaft and lubricant reservoir, for
the lubricating, automatically or otherwise, of its bearings or journals.
It consists in making a tube serve as an axle or shaft so that the bore of the
same can be utilized as a reservoir for a lubricant necessary for the lubrication of
its bearings or journals by means of mechanical fittings therin contained, which are
to be actuated by suitable attachments fitted on one or both ends of same, which
will be for automatic or hand-feed.
The drawings herein referred to are those filed with the Provisional Speci-
fication.
Fig. (1) is a drawing in section of the invention as applied in the construction of
a colliery tram axle, with the arrangement for the automatic working of the
lubricating pistons (L´P) by means of the toothed working disc (T W˜D) and
appertenances.
The spaces in the axle for the necessary lubricant are those shown in the tube
between the combination plug (CP) and the terminal plug (T P) respectively and
their lubricating pistons (LP)
Fig. (2) represents part of one end of tube (T) in Fig. 1. showing the combination
plug slightly modified for hand feed. It will not always be possible or convenient
to use the axle or shaft fitted with the toothed working disc (T W D) and
appertenances, therefore it is necessary to fit the axle thus for actuating the
pistons (LP) by hand.
Fig. (3) gives plan of position of set pin (S P) in (Fig. 1) showing the split pin
necessary for preventing same from unscrewing, recessed in a groove formed across
the set pin hole in collar (C) a cotter can be substituted for this set pin when
found more convenient.
Fig. (4) is an enlarged cross section of tube and screw in Fig. 1. showing face
view of pistons (LP) valve in same, and position of screw hole, which is considerably
out of centre, this is necessary for the self guiding of pistons (LP) when the
screw (S) is caused to revolve.

page_text: Fig. (5) is an enlarged section of part of tube (T) in Fig. 1. with outlet
holes (OH) shown fitted with a check valve (CV) chiefly necessary for use when
a liquid lubricant is used, as it will close when the pistons are not working, thereby
making the loss of lubricant impossible.
The accompanying drawings represent the invention as appliel in the construction
of a colliery tram-axle.
Fig. 1. is a section of the tube containing the lubricating pistons (LP) which are
caused to travel in opposite directions by means of a combined right and left hand
threaded screw (S) for the purpose of forcing the lubricant through the outlet
holes (OH) which are provided with check valves (CV) which may be made of
clastic material for preventing the loss of lubricant when the same is not required.
In this (Fig. 1) is the toothed working disc (T W D) for the automatic working
of the lubricating pistons (L P); this toothed working disc is connected with the
screw (S) by an intervening toothed shank (T S) formed so as to engage with a
similarly toothed key (TK) which slides on the squared part of the end of the
screw (S, which is provided with a combination plug (CP) part of which is made
of joint making material which is built up so as to serve as a joint on inside face of
tube and on the circumference of part of the screw end; it also forms the stop
block or support for a suitable spring (RS) necessary for keeping the toothed
key (TK) well up to the toothed shank (TS) this arrangement is intended to
obviate the possibility of the lubricating pistons (LP) travelling in a contrary
direction to that for lubricating.
11 it happens that the toothed working disc (T W D) were to come in contact
when the tram travels, with anything other than that provided for the right working
of same, this is to be in the form of an arm or lever arranged so that the toothed
working disc (TWD) will engage with a suitable rack or blade provided at the
end of the arm or lever and hence be worked in the right direction for lubricating.
This arm or lever is to be held at a suitable angle to the road on which the tram
travels in a position selected by the users and to be supported by weights, or springs,
if sufficient weight or strength to keep it at the same angle so as to cause the toothed
working discs (T W D) to revolve when the tram passes, after successive journeys
thus automatically actuated, the lubricating pistons (LP) will have travelled their
course in the tube (T) riz-up to the outlet holes (OH) which result in the
toothed working disc remaining rigid when next in contact with the rack or blade
of arm or lever, and as the screw (S) is made strong enough to resist the effect of
the weights or springs used with the arm or lever the result will be that the arm or
lever, which is pivoted, will yield radially, to the toothed working disc (TWD)
when the tram passes, untill the grip between the disc and rack or blade is. lost,
resulting in the sudden return of the arm or lever and simultaneously giving an
alarm which serves to show that the axle or shaft wants refilling with lubricant;
this alarm is produced by a bell or gong or other suitable signalling apparatus
provided in connection with the arm or lever. Where hand-feed alone can be used;
it is only necessary to extend the screw in length towards the end of tube (T)
and to make the combination plug (CP) of a suitable design to serve the purpose
of a fixed plug necessary for holding the screw (S) in true working position in
tube (T).
Fig. 2 shows the combination plug (C P) in the end of tube for hand feed.
Fig. 3 gives plan of position of set pin (S P) necessary for holding toothed
shank (TS) or combination plug (CP) in position. The set pin is here shown
conveniently screwed through a collar (C) in most cases a necessary adjunct to an
axle or shaft, and as the same are liable to great jerks when at work, which. would
cause the loss of screws, it is deemed necessary to provide against the possibility
of such loss by making a groove across the screw hole for the introduction of a split
pin (S P).
By this arrangement. the set pin (SP) (more than one if necessary) is screwed
down so as to be within. the outside dia..of the collar, so as to be clear from the
danger of being knocked about..

page_text: (RH) is the recharging hole. When a new supply of lubricant is necessary,
a connection by means of a suitable tube is made between this hole and the
vessel containing the lubricant, the lubricant is then forced in so as to fill the
space between the pistons, which are at their extreme travelling distances (viz.—as
far as the outlet holes (O HI) ), this being done the connection is withdrawn, and
the recharging hole (RH) is stopped by means of a plug, or other suitable stopper,
so that when the pistons are worked back to the centre of the axle or shaft, it will
be possible for the lubricant to pass through the back pressure valves (BP V)
provided in the lubricating pistons (LP). The (B. P.) valves in pistons can be
dispensed with if each lubricant space is provided with a recharging hole so as to
be in front of the pistons when they are drawn back to their extreme positions near
centre of length of tube, instead of the one (RH) shown in centre of tube
(see Fig. 1).
Fig. 4 is an enlarged cross section of tube, and screw, showing a face view of
piston, valve in same, and the position of screw hole, which is considerably out of
centre by this arrangement the pistons will guide themselves in the circular tube
thereby dispensing with the necessity for providing a groove in the tube, which
would weaken it and make it difficult to produce joint making buckets (B) and
rings for the lubricating pistons (LP) equal to those necessary for a circular tube;
(this also applies to a tube other than a circular bore). (L) is a liner between
toothed shank (T S) and part of tube (G E) is the grip end of screw (S) for hand
working by means of a key, which may have 3, 4, or any other number of squares.
(TP) is a terminal plug. (JR) joint ring. (C) cotter. (W) washer or loose
collar.
A collar with screws such as those shown at the feed ends will serve the same
purpose.
Fig. 5 is a section of part of tube with outlet hole (OH) shown enlarged.
The check valve (CV) contains a slit which will open when the pressure is on
from inside tube (see dotted lines), so as to allow the lubricant to pass out.
This valve being flexible, will close when the pressure is stopped; it may be
conveniently held in position by a washer, screwed or otherwise fastened in the
outlet hole.
Very few modifications in the construction of the principal parts described in
this Specification is necessary for the application of this method of lubrication, to
other vehicles and working systems with which axles or shafts are used.
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. An ordinary metal tube so as to serve as an axle or shaft for vehicles with its
internal space used as a lubricant reservoir.
2. Fitted internally with apparatus as described in the foregoing Specification
for efficiently forcing lubricant to its working bearings by accessible connections
provided with same.
