Improvements in and relating to the Connection of Wheels and
Axles of Carriages.
I GODFREY JOBSON, of Grange Court, Ealing, in the County of Middlesex
Ironfounder do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in means or apparatus for use in securing
wheels of vehicles upon their axles and for effecting the lubrication of the contact
surfaces of the wheels and axles, especially when employing thicker or more solid
lubricants, or greases, so as to economise the quantity employed and the labour
involved in frequently replenishing the supply and to attain other advantages;
also in protecting the parts.
space
In carrying out my invention I employ an axle arm preferably of the taper
form, in which from the outer end for a suitable distance is formed a small passage
which by say-one, two, or more branch passages communicates with the surface
of the axle arm in contact with the inner surface of the axle box, or the
between the same. The axle box around the outer end of the axle arm is of
diminished external diameter and screw threaded externally of such neck and upon
this neck is screwed a washer and against this again is screwed on a bell mouthed.
or other suitably shaped, circular shield screwed at its inner and thicker edge
internally.
The outer end of the axle arm has a small extension of plain surface preferably
of reduced diameter, to receive a washer, for a distance equal to the thickness of
said washer and it is screw threaded for the remainder of its length. On this
screw threaded extension is secured next to the plain washer a threaded nut or
washer and then a flanged hexagon or other shaped boss internally screw threaded
to fit this extension of the axle arm and again screw threaded externally of the
larger diameter or peripheral surface of the circular flange.
Upon this larger diameter screw threaded is secured adjustably a suitable screw
cap, in which is contained the lubricant to be supplied to the contact surfaces.
By these means, between the inner surfaces of the screw or like cap, the outer
surfaces of the flanged boss, the end of the axle arm and the surfaces of the
passages, is formed a communicating space or series of spaces to contain lubricant,
and by a slight turn of the screw or like cap from the exterior by the hand of the
coachman, or otherwise, pressure can be applied to the mass of the lubricant
matter, by diminishing the size of the screw or like cap chamber, to force the
lubricant to the parts where it is required.
Around the outer diameter of the circular shield or flange or projecting protecting
part may be formed an annular peripheral groove or channel into which can be sprung
or fitted an india rubber, or elastic, ring adapted to reduce the destructive effect of
any concussion of circular shield or flange with another body; and a cover may be
fitted, somewhat plug fashion within the circular shield, flange, or dished part and
be therein held by elastic projections-a pin, or connection sliding in a retaining
bearing serving to prevent entire disconnection and possible loss of the plug, which
plug serves not only as a dust excluder, but also as an additional element of strength
and protection to the enclosed parts.
Or the cover to the flanged shield may be formed as a cap and the groove for the
elastic concussion ring be formed on the cap, and the cap be made with a screw, or
like, connection to the circular flanged part or shield.
The cap of the lubricant chamber may be formed in one with the hexagon or
like boss and a screw plug easily accessible he used to cause pressure on the

page_text: contained lubricant to force it to the parts requiring lubrication, or these details
may be otherwise varied without departing from the essential features of the
invention.
A key way may be cut through the washer or hexagon or other boss which fits
over a peg fitted into the small extension of the plain surface on the end of the
axle arm
or the peg may be in the washer and the key way be in the axle
arm end.

Improvements in and relating to the Connection of Wheels and
Axles of Carriages.
I GODFREY JOBSON, of Grange Court, Ealing, in the County of Middlesex,
Ironfounder 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 improvements in means or apparatus for use in securing
wheels of vehicles upon their axles and for effecting the lubrication of the contact
surfaces of the wheels and axles, especially when employing thicker or more solid
lubricants, or greases, so as to economise the quantity employed and the labour

In carrying out my invention I employ an axle arm preferably of the taper form,
in which from the outer end for a suitable distance is formed a small passage which
hy say one, two or more branch passages communicates with the surface of the
axle arm in contact with the inner surface of the axle box or the space between
the same.
The axle box around the outer end of the axle arm is of diminished external
diameter and screw threaded externally of such neck and upon this neck is screwed
a washer and against this again is screwed on a bell mouthed or other suitably.

The outer end of the axle arm has a small extension of plain surface preferably
of reduced diameter to receive a washer, for a distance equal to the thickness of
said washer and it is screw threaded for the remainder of its length.
On this screw threaded extension is secured next to the plain washer a threaded

of any concussion of circular shield or flange with another body; and a cover may

axle arm or the peg may be in the washer and the key way may be in the axle
arm end.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a longitudinal section of axle arm, axle box, hub, protecting cap or
guard with its loose plug or cap. It also shews the containing cap n² internally
threaded for holding the grease; also it shews the externally threaded nut n' which
acts as a lock nut to prevent the other nut n and the collar or collet from coming
off. It also shews the central and branch passages for grease to reach the
axle arm.
Fig. 2 is an end elevation of the cover or guard with its plug in.
Fig. 3 shews the cover with the plug removed shewing the bracket i for sliding
pin which prevents the plug being lost, or stolen and also the two lugs behind
which the elastic points of the plug engage when turned round.
Fig. 4 is a sectional plan of cover, or guard shewing these lugs in section, and
also shewing the rubber ring or annulus k for excluding dust or water from interior
of cover.
Fig. 5 is an internal or back view of the plug.
Fig. 6 is an alternative method of fixing the cover on to the axle box so that it
can be readily removed for the purpose of fastening or unfastening the lock nuts
and collet on end of axle arm.
a (Fig. 1) is the axle arm of substantially ordinary construction with diminished
end or nose a plain for part of the length next arm on which the collet r rests and
screwed for remainder of its length to receive an ordinary nut n and also the
externally threaded nut n which two nuts are locked against each other as is well
understood.
n² is the containing cap internally threaded for containing the grease by turning
which the grease is forced along the central passage a² and out at the branch
passages of which although three a³, a³, a³ are shown there may be one, or more,
to the face of the axle arm and box. d is an internally and externally threaded
collar or nut which forces the hub c against the shoulder of the axle box b. On
this collar d is screwed the guard e. f is a ring or annulus of rubber or other
suitable material for receiving the blow or impact of a foreign body and acts as a
buffer or guard to prevent distortion of e and plug . is a plug or annulus
carrying a rubber ring which is forced against a shoulder of the cover e by the
elastic points m when engaging the lugs p Fig. 4.
is a ring fitting within the annulus g (but free to revolve) and held in its place
by a circular plate of metal o to both of which the elastic points m are attached.
By turning the elastic points m can be engaged or disengaged with lugs p and
the plug g secured or removed at pleasure for the purpose of getting at the cap n
in order to turn it round and so force the grease along the central passage. i is a
bracket attached at e through which slides a headed pin securely fixed in g to
prevent loss of plug g, c is an ordinary hub.
