page_text: LETTERS PATENT to Benjamin Tillett, of Pine Grove Villa, Fairlop Road,
Fillebrooke Estate, Leytonstone, in the County of Essex, Builder, for the
Invention of "IMPROVEMENTS IN HUBS OR NAVES OF WHEELS FOR VEHICLES."
A communication from abroad by Erastic S. Bennett and John H. Rowland, of
Denver, State of Colorado, United States of America.
PROVISIONAL SPECIFICATION left by the said Benjamin Tillett at the
Office of the Commissioners of Patents on the 3rd January 1879.
BENJAMIN TILLETT, of Pine Grove Villa, Fairlop Road, Fillebrooke Estate,
Leytonstone, in the County of Essex, Builder. "IMPROVEMENTS IN HUBS OR NAVES
OF WHEELS FOR VEHICLES." A communication from abroad by Erastic S. Bennett
and John H. Rowland, of Denver, State of Colorado, United States of America.
The objects of this Invention are chiefly to furnish a hub in which no wood shall
be required; to adapt the same to boxes in common uso in such a manner as that
they may be readily and securely fastened in place without wedging or the use of
the "sweep" for truing up; to provide a long bearing for the spokes in the hub to
avoid shoulders, tenons, bolts, and rivets at the hub end of the spokes, and thereby
preserve the strength of the full size of the wood; to form nearly the whole in one
casting if desired, so that no bands need be added; to provide a reservoir for oil,
by means of which the axle may be automatically lubricated, or at will, without
the removal of the wheel; to arrange so that the spokes may be easily and quickly
removed without injury when the wheel is undergoing repairs; to arrange so that
by simple forcing the spokes into the hub the former may always be tightened in
the latter; to provide a means by which old worn out boxes may be easily removed
from the hub and new ones substituted without injury to the wheel; and to
combine the utmost strength and symmetry with the least possible weight and
cost.
The spoke mortice may bo made slightly tapering, and is provided with the
beads or spurs between which the spokes are driven. In driving the spokes these
spurs become embeded in the corners of the former, and serve to hold the spokes
in place, both laterally and endwise. The spurs may be of any desired shape as to
their transverse section, and may consist of continuous beads from the periphery of
the hub mortice to the bottom of the samo, or they may be rows of projections.

page_text: The spoke mortice is strengthened by the webs. The out end of the hub is
provided with an internal flange which is bored to fit the outer end of the box, the
latter being turned so that a small shoulder is formed. The inner end is provided
with a screw thread into which a ring is fitted. This ring is provided with holes
or indentations for the reception of the jaws of a suitable wrench, and is bored to
fit the inner end of the box, so that when in position it forms an oil tight joint
with the box.
The hubs may be cast with the bands upon them all in one piece or casting, or
without either, with a view to putting them on afterwards.
A screw, as an oil feeder, is provided with a lock or jamb nut and a conical
point, the latter finding a seat in a suitable aperture in the box. Any other simple
device may be substituted.

BENJAMIN TILLETT, of Pine Grove Villa, Fairlop Road, Fillebrooko Estate,
Leytonstone, in the County of Essex, Builder. "IMPROVEMENTS IN HUBS OR NAVES
OF WHEELS FOR VEHICLES." A communication from abroad by Erastus S. Bennett
and John H. Rowland, of Denver, State of Colorado, United States of America.
The objects of this Invention are chiefly,-
1. To furnish a hub in which no wood shall be required to adapt the same to
boxes in common use in such a manner as that they may be readily and securely
fastened in place without wedging or the use of the "sweep" for truing up.
2. To provide a long bearing for the spokes in the hub.
3. To avoid shoulders, tenons, bolts, and rivets at the hub end of the spokes, and
thereby preserve the strength of the full size of the wood.
4. To form nearly the whole in one casting if desired, so that no bands need be
added.
5. To provido a reservoir for oil, by means of which the axlo may be automati-
cally lubricated, or at will, without the removal of the wheel.
6. To arrange so that the spokes may be easily and quickly removed without
injury when the wheel is under-going repairs.
7. To arrange so that by simply forcing the spoke into the hub the former may
always be tightened in the latter.
8. To provide a means by which old worn-out boxes may be easily removed from
the hub and new ones substituted without injury to the wheel, and to combine tho
utmost strength and symmetry with the least possible weight and cost.
In the Drawings which represent the Invention Figure 1 is a longitudinal
section; Figure 2, a transverse section; Figure 3, a top or face view of the spoke
mortice. A, A, represents the shell of the hub; B, the box; C, the spoke space or
"mortice;" D, the spokes; E, the oil chamber; F, oil feeder; G, front or outside
band; H, inside or "sand band;" and R, the axle.
The spoke mortice, which may be made slightly tapering, as shown at C, is
provided with beads or spurs I between which the spokes are driven, as in Figure 2.
In driving the spokes these spurs become embedded in the corners of the former,
and serve to hold the spokes in place, both laterally and endwise.
The spurs may
be of any desired shape as to their transverse section, and may consist of continuous
beads from the periphery of the hub mortice to the bottom of the same, as shown
generally in the Drawings; or they may be of any length, or as rows of projections,
as at J, J. The spoke mortice C is strengthened by the webs K and K'. The
outer end of the hub is provided with an internal flange L which is bored to fit the
outer end of the box B, the latter being turned so that a small shoulder is formed,
as at M. The inner end is provided with a screw thread N, into which the ring O
is fitted. This ring is provided with holes or indentations P for the reception of
the jaws of a suitable wrench, and is bored to fit the inner end of the box B (which
is also turned, as at M'), so that when in position it forms an oil tight joint with
the box B.
The hubs may be cast with the bands G and H upon them all in one piece or
casting, or they may be put on afterwards, as shown by dotted lines Q, Q.
As an oil feeder I have shown a simple screw F provided with a lock or jamb
nut and a conical point, the latter finding a seat in a suitable aperture in the box B.
Any other simple device may be substituted.
It will be seen that these spokes have a longer bearing in the hub than is usual;
that while they are held firmly in position they are not weakened by either tenons,
rivets, or bolts, that they may be withdrawn without injury; that when loose,
tightening the rim tightens them both laterally and endwise; that the "mortice
"

page_text: cannot spread or open since the shell A being shaped as to form braces, which are
amply reinforced by the webs K, K.
Having now described the nature of the said Invention, and in what manner the
same is to be performed, I declare that I claim as the Invention communicated to
me as aforesaid,--
The construction of cast metal hubs or naves, as described, said hubs being
hollow with oil chamber, and with beads in spoke's mortice, and available for
existing axle boxes, as set forth, and as shown in the annexed Drawings.
In witness whereof, I, the said Benjamin Tillett, have hereunto set my hand
and seal, this Second day of July, in the year of our Lord One thousand
eight hundred and seventy nine.
Witness,
