Improvements connected with Wheels for Carriages and other
Vehicles.
I, JOHN HAYDOCK, of White Bull Stables, Blackburn, in the County of
Lancaster, Cab Proprietor, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements connected with carriage and other wheels
of that class in which a cushion of india rubber or other elastic material is inter-
posed between the axle bush and the hub or nave of the wheel for the purpose
of reducing vibration and preventing the wrenching or loosening of the wheel
spokes.
In carrying out my. invention I employ a cylindrical metal box (hereinafter
termed the "cushion box") flanged inwardly at each end and within this box I
insert one or more rings or hollow cylinders of elastic material-preferably india
rubber. I provide an inner tubular lining or bushing (preferably of thin sheet
metal) interposed between the india rubber and the axle bush and this lining or
bushing is divided longitudinally so as to form one or more segments. These
segments have their ends turned up at right angles in the form of flanges which fit
or rest against the two ends of the india rubber cushion or elastic filling the
arrangement of segmental lining facilitating the introduction or pushing in of the
axle bush through the elastic filling and also its withdrawal therefrom for repairs
and other purposes without the necessity of withdrawing the cushion box from its
place in the wheel nave. The cushion box is fastened in place in the wheel nave in
a similar manner to that which obtains in fastening an ordinary axle bush.

In a modification of the arrangement above described instead of employing one

In another modification I divide the cushion box and segmental linings into two
halves and mid way of the axle bush, and between the divided cushion box I fasten
upon the periphery of the said axle bush (preferably by means of screw-threading)
a check ring or collar which serves to prevent the said axle bush from moving
end wise and withdrawing itself from the wheel nave in the event of the outer end
of the axle bush snapping or breaking off at the part where it is weakened
by being screw-threaded for the reception of the retaining nut hereinbefore
referred to.

Improvements connected with Wheels for Carriages and other
Vehicles.
I, JOHN HAYDOCK, of White Bull Stables, Blackburn, in the County of
Lancaster, Cab Proprietor, 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 connected with carriage and other wheels of
at class in which a cushion of india rubber or other elastic material is interposed
between the axle bush and the hub or nave of the wheel for the purpose of reducing
vibration and preventing the wrenching or loosening of the wheel spokes.
In carrying out my invention I employ a cylindrical metal box (hereinafter
termed the cushion box") flanged inwardly at each end and within this box I
insert one or more rings or hollow cylinders of elastic material-preferably india
rubber. I provide an inner tubular lining or bushing (preferably of thin
sheet metal) interposed between the india rubber and the axle bush and
this lining or bushing is divided longitudinally so as to form one or more
segments. These segments have their ends turned up at right angles in the
form of flanges which fit or rest against the two ends of the india rubber
cushion or elastic filling the arrangement of segmental lining facilitating the
introduction or pushing in of the axle bush through the elastic filling and also its
withdrawal therefrom for repairs and other purposes without the necessity of
withdrawing the cushion box from its place in the wheel nave. The cushion box
is fastened in place in the wheel nave in a similar manner to that which obtains in
fastening an ordinary axle bush. I cause the axle bush to project somewhat through
the cushion box and upon its projecting end I arrange a screw nut which tightens
up against the turned up ends or flanges of the lining or bushing segments and
serves to retain the axle bush in position by preventing its endwise movement.
Outside the said retaining nut and answering as a protector therefor is a flange
projecting from the ordinary axle cap which latter is screwed into the axle bush
in the usual manner. The cushion box at its inner end has a projecting pin or stud
which may be arranged to enter a hole or slot in the enlarged or oil chamber part
of the axle bush or vice vers so that the two may be held together and independent
rotary movement of the said axle bush may be prevented.
In the accompanying drawings,
Fig. 1 is a sectional plan view and
Fig. 2 a cross section of a wheel hub having my said improvements applied thereto.
Fig. 3 is an end view of the "segmental lining."
The succeeding figures illustrate modifications of the arrangement shewn at
Figs. 1 and 2.
A is the wheel hub or nave B B the wheel spokes C the axle D the axle bush
and E the axle cap. The solid black in the several figures indicates the india
rubber cushion or elastic filling.
a is the inner tubular lining or bushing of thin sheet metal divided longitudinally.
At Fig. 3 the said lining is shewn divided into three segments or parts but I find
it more convenient in practice to have only one segment (see Fig. 6) the said lining
being then more easily bandled or manipulated and at the same time retaining the
required amount of flexibility or compressibility. b is the cushion box containing
the india rubber filling. c is an annular metal plate or washer screwed fast to the
wheel hub which serves to assist in holding the cushion box in place end wise at one
end or side of the hub whilst a flanged screw nut e-with an interposed leather
washer d for preventing the entry of oil or dirt-holds it in place at the other.
The said nute screws on to the outer end of the axle bush D the screw-threading
of the latter being preferably of less diameter than the body part of the said bush

page_text: and in an annular recess at the opposite end of the axle bush I introduce another
leather washer d¹ and also a thin metal washer or loose collar f. 9 g are pins or
lugs on the axle bush D which enter slots or openings in the fast rings cand prevent
rotatory movement of the said bush independently of the cushion box b. h² are
lock nuts screw-threaded in opposite directions on the end of the axle C and i is a
hole for the reception of a safety pin in the form of a split cotter. The cushion
box illustrated at Figs. 1 and 2 is of solid metal and is of suitable strength for
being wedged up tight in the wheel nave in a similar manner to that which obtains
in fastening in an ordinary axle bush. But I find in practice if the cushion box be
made of thin sheet metal with a longitudinal opening or division (see Fig. 7) or in
other words in the form of a segmental compressible covering I am enabled to
force or squeeze the cushion box tightly into the nave by the compression of the
elastic filling and to dispense with the necessity of wedging up as by the usual
method.
Figs. 4, 5, 6, and 7 illustrate a similar arrangement of apparatus to that shewn at
Figs. 1, 2, and 3 except that in the former figures the segmental lining is in one
piece instead of in three and the cushion box & is of thin sheet metal with a single
longitudinal opening.
Figs. 8 and 9 illustrate an arrangement of similar apparatus in which the cushion
box 6 is dispensed with and the segmental lining a retained and also shew the india
rubber or elastic filling in several pieces or tubular lengths instead of in one tubular
piece as in the remaining figures. When the cushion box or outer covering b is
omitted the wheel spokes B B as they gradually work through or beyond their
sockets or holes in the wheel nave meet the periphery of the india rubber tubing
which forms a cushion upon which the ends of the wheel spokes rest the vibration
of the spokes being thus taken up or prevented and the usual noise caused by loose
spokes when the wheel is in motion being reduced.
In practice I prefer not to employ either of the modifications referred to in the
latter part of my Provisional Specification as they are more complicated and more
expensive to produce (than the arrangements herein described and illustrated)
without affording commensurate advantages.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is :-
1. The combination with a cylindrical box containing elastic filling of an inner
tubular sheet metal lining divided longitudinally substantially as described aud
shewn in the drawings for the purpose set forth.
2. The combination with an axle bush surrounded or encircled by elastic filling
of a tubular sheet metal lining divided longitudinally the said lining being
interposed between the axle bush and the elastic filling substantially as described
and shewn in the drawings for the purpose set forth.
3. In combination with an axle bush and attendant parts of the kind herein
described and illustrated the use or employment of a projecting pin or pins such
as g for the purpose specified.
4. The combination with an axle bush surrounded or encircled by elastic filling
and a tubular sheet metal lining divided longitudinally of a retaining nut such as e
for the purpose specified.
5. The general construction arrangement and combination of parts constituting
the improved method of cushioning the nave or hub of a vehicle wheel substantially
as described and shewn in the drawings.
