COMPLETE SPECIFICATION.
Improvements in Hubs for the Wheels of Vehicles.
1, HENRY EDWARD MOEBUS, of Woodstock, in the Province of Ontario, and
Dominion of Canada, Inventor, 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 vehicle hubs in which an elastic filling is employed to
take up the vibrations, and thereby render riding easier, and make vehicles more
durable by lessening the jar.
The object of the invention is to provide an improved hub of this character, in
which the filling of rubber is vulcanised to the axle box, and to the hub-receiving
shell, and interlocked with the said shell, or the spokes, and with the box, to obtain
a solid filling, and also prevent any rotary movement of the filling or shell inde-
pendently of the box; and a further object is to permit the necessary longitudinal
yielding of the hub, while preventing displacement of the parts.
Reference is to be had to the accompanying drawings forming a part of this
Specification, in which similar letters of reference indicate corresponding parts in
all the figures.
Figure 1 is a longitudinal sectional view of a hub embodying my invention, the
section being taken on line 1-1, Figure 2.
Figure 2 is a transverse section on line 2-2 Figure 1.
Figure 3 is a longitudinal section on line 3-3 Figure 4, shewing a modification.
Figure 4 is a transverse sectional view of same on line 4-4 Figure 3; and
Figures 5 and 6 are respectively longitudinal and transverse sectional views
shewing a further modification.
Figures 7 and 8 are respectively longitudinal and transverse sections shewing a
further modification.
Referring particularly to Figures 1 and 2, the hub is provided with an axle
box A, adapted to receive the axle spindle, and at its inner end an integral flange a
is formed. At the outer end a removable flange a¹ is secured to the box, which
flanges prevent end wise displacement of the rubber filling B of the hub.
In order that the rubber filling may interlock with the axle box, bolts C are
provided which extend longitudinally of the hub, passing through one flange of the
box at a', and screwing into the other, as will be clearly understood from Figure 1,
the bolts thereby forming an attachment to, and virtually a part of the box, so that
all rotary movement of the rubber relatively to the box is prevented.
The bolts, outside of the flange a¹ are provided with nuts a² by which the said
flange is forced home on the axle box. Set screws a' may also be provided for
securing the hub of the flange a¹ to the axle box.
The outer shell D of the hub is provided with spaced external flanges d for
receiving the spokes E, and between the flanges apertures d' are preferably formed
in the shell, in order that the tenons e of the spokes, or of some of them, may
extend into recesses formed in the rubber filling B.
On the shell D there are also formed spaced internal rings F, preferably of
skeleton form, in order that the rubber may take a better hold. Extending
longitudinally of the hub and connecting such internal flanges, are rods or bolts f
and by means of such flanges and rods, thus formed on or affixed to the shell, the
rubber filling is caused to interlock with the shell, and prevent rotary movement of
the latter relatively to the rubber. The flanges F are formed with openings f¹,
through which the bolts C of the axle box freely pass, and into these openings, and
the openings f in the rings, the rubber extends. By thus effectively interlocking

page_text: the rubber with the box and shell, the necessary lateral and vertical yielding is
permitted, while all undue longitudinal play or displacement is prevented.
An exterior cap G, is affixed to the hub in any approved manner.
In practice the shell and box of the hub are put together, and suitable moulds
and clamps are arranged thereon, including a form by which the recesses b for the
spoke tenons are formed, and the hub is filled with rubber, the removable flange a¹
being tightened up by the nuts a² subsequently to entering the rubber filling,
whereby the flanges and bolts are availed of to compact the filling. The hub is
then placed in a vulcaniser to vulcanise the rubber.
In the form shewn in Figures 3 and 4, rotary movement of the shell D' relatively
to the filling is prevented wholly by the tenons e¹ of the spokes E', and rotary
movement of the rubber relatively to the box is prevented by studs a³ secured to
the flanges a, a of the said box, and extending into the rubber toward each other,
and by bolts C that alternate with said studs. In this form also, the box includes
a thimble A', which is secured to the internal box A' by a groove and feather
connection, the flanges a* a' being on the said thimble.
In the form shewn in Figures 5 and 6, there are formed on the thimble A' of the
axle, radial ribs a³ that extend longitudinally of the thimble, between the
flanges a a', which are the same as in Figures 3 and 4, except that the flange a² is
held in place by a threaded connection with the axle box, and on the outer spoke-
receiving shell or casing D¹, there are formed internal ribs D2 that alternate with
the ribs as, and, like the latter, extend longitudinally of the hub between the
flanges a and a².
The ribs a and D2 are formed with openings d² into which the rubber enters for
taking proper hold, and such ribs terminate short of the flanges a, a', so that a
considerable cushion of rubber will enter between said flanges and ribs, to ensure
that the hub readily recovers its normal condition after a side thrust such as may
be occasioned by a car track. This cushion is also provided for at the inside of
the flanges in the construction shewn in the other figures.
In the form shewn in Figures 7 and 8, A represents the axle box,-B the rubber
filling, D the spoke receiving shell,-E the spokes, which may either extend
partly into the rubber filling as shewn in Figures 7 and 8 of the drawings, or may
only pass through the shell, as indicated in dotted lines in Figure 8-a represents
four or more rows of studs protruding from the exterior of axle box; d³ represents
four or more rows of studs protruding from the interior of the spoke receiving
shell, placed in position in such a manner as not to be in a line of circumference
with the studs a³ of the axle box-a is the permanent flange-a¹ is the removable
flange furnished with a screw thread, so that it can be screwed on after the rubber
filling has been introduced. The rubber filling is vulcanised to the axle box and
the spoke receiving shell in a similar manner as in the other systems while the
studs a³ and d³ serve to keep such filling in position relatively both to the axle box
and the spoke receiving shell.
The flanges for holding the spokes are similar to those described and shewn with
respect to the other systems.
In all cases the rubber is vulcanised both to the shell and box, and interlocks
with both, whereby the hub will be firm, and all looseness and abnormal movement
will be prevented. In all cases also, undue friction between the metal parts in the
yielding of the filling is prevented.
Further the flanges of the box in all the modifications, prevent all lateral
displacement, while permitting the necessary yielding in response to side thrusts.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1. The herein described hub, comprising an axle box, a spoke receiving shell,
and an interposed filling of rubber vulcanised both to the box and shell, and

page_text: interlocked to prevent rotary movement of either the box or shell relatively to
the filling, substantially as described.
2. The herein described hub, comprising an axle box, a spoke receiving shell,
and an interposed filling of rubber vulcanised both to the box and shell, and
the box and shell being interlocked with the rubber, to prevent rotary movement
of either relatively to the rubber, the box having a fixed and a removable
flange, which prevents undue movement of the shell and filling longitudinally of
the hub, substantially as described.
3. The herein described hub, comprising an axle box having flanges, and bolts
extending between said flanges, an outer shell having internal rings or flanges which
are also united by bolts or rods, and an interposed filling of rubber vulcanised both
to the shell and box, substantially as described.
4. The herein described hub, comprising a box having flanges, and provided with
inwardly extending studs on said flanges, an exterior shell, and an interposed filling
of rubber vulcanised both to the shell and box, substantially as described.
5. The herein described hub comprising a box having flanges, and having radial
ribs extending longitudinally of the hub between the flanges, an exterior shell
having internal longitudinal ribs also extending longitudinally between the box
flanges, and alternating with the ribs of the box, and an interposed filling of
rubber, vulcanised both to the box and shell substantially as described.
6. The herein described hub comprising a box provided with flanges, and with
inwardly extending studs, a spoke receiving shell provided with outwardly extending
studs arranged alternately with the studs on the box, and an interposed filling of
rubber vulcanised both to the shell and box, all substantially as described.
7. The herein described hub comprising an axle box, an exterior spoke receiving
shell, and a filling of rubber centrally of the hub, and vulcanised to the box and
shell, the said shell being free to move in the direction of the length of the hub, in
response to side thrusts, and the rubber serving to permit also a yielding of the
shell transversely of the hub, substantially as described.
