PROVISIONAL SPECIFICATION left by the said Henri Adrien Bonneville at
the Office of the Commissioners of Patents on the 24th May 1882.
HENRI ADRIEN BONNEVILLE, of the British and Foreign Patent Offices, 8, Rue
de la Chaussée d'Antin, Paris, France, and 90 Cannon Street in the city of
London, Patent Agent, CERTAIN NEW AND USEFUL IMPROVEMENTS IN HUBS FOR
VEHICLE WHEELS, communicated to me by Jules Lajeunesse and Edmond Armant,
two persons resident at Montreal in the district of Montreal and Province of
Quebec, in the dominion of Canada
This invention relates to improvements in that class of hubs in which metallic
bands are used for the purpose of strengthening the joints between the hub and
the spokes, and for preventing the wood centre from splitting.
The improvements have for their object to improve the appearance of the hub
and render same as syminetrical and light as the most finely finished hard wood
hub, allowing the use of cheaper wood than at present, and at the same time to
greatly strengthen the same, and prevent it from splitting as the spokes are driven
in, and allow the ordinary machine made spoke with plain tenon and shoulders to
be used without any liability of said shoulders being split off in driving same, or
from the jolting of the vehicle; in fine, the spokes are bound firmly in and to the
hub, and the hub also is preserved from all danger of splitting.
The invention consists in the combination with a wooden hub mortised in the
usual way, of a plain thin metallic band surrounding the hub, and provided with
[Pins1

page_text: mortises to match those in [the hub, but larger than the latter, and bevelled on
their inner sides. The tenons of the spokes are driven into the mortises in the
wooden hub through the larger mortises in the metallic band, and the shoulders of
said spokes thus bear upon ledges formed by the peculiar manner in which the
metallic band fits the wooden hub; the bevelled inner edges of the mortises in said
metallic band forming seats for the spokes.
For more complete comprehension of the invention, reference must be had to the
annexed drawing in which similar letters of reference indicate like parts, and
where
Fig. 1 is a side elevation of hub with metallic band in place, but without spokes;
Fig. 2 a cross section of same on line X X. Fig. 3 a longitudinal section with
spokes in place; and Fig 4 a detail of spoke.
"
In these drawings the hub and metallic band are constructed with " dodging'
mortises, but it will be understood that the invention is equally applicable to hubs
in which the mortises are in a line with each other; the invention however, has
particularly beneficial results when used with "dodging" mortises.
A is the wooden hub, turned in the usual or any approved way, and provided
with mortises B B, for the spokes. As shown in Fig. 1. this hub is slightly conical,
or bevelled from inside to outside, but this is not absolutely necessary. Over the
wooden hub is slipped a circumferential metallic band C of just sufficient size or
diameter to slide easily into place; this band C is provided with oblong slots or
mortises c c one for each mortise in the hub A, but these slots c c are somewhat
larger than the mortises B B, so that when the band C is in place, ledges a a will
appear on the hub at each side of mortises. The inner edges of the slots or
mortises c c are bevelled as shown particularly in Figs. 2. and 3.

HENRI ADRIEN BONNEVILLE, of the British and Foreign Patent Offices, 8 rue
de la Chaussée d'Antin, Paris, France, and 90 Cannon Street, in the city of
London, Patent Agent, CERTAIN NEW AND USEFUL IMPROVEMENTS IN HUBS FOR
VEHICLE WHEELS, communicated to me by Jules Lajeunesse, and Edmond Armant,
two persons resident at Montreal, in the district of Montreal, and province of
Quebec, in the dominion of Canada,
This invention relates to improvements in that class of hubs in which metallic
bands are used for the purpose of strengthening the joints between the hub and
the spokes, and for preventing the wood centre from splitting.
The improvements have for their object to improve the appearance of the hub,
and render same as symmetrical and light as the most finely finished hardwood
hub, allowing the use of cheaper wood than at present, and at the same time to
greatly strengthen the same and prevent it from splitting as the spokes are driven
in, and allow the ordinary machine made spoke with plain tenon and shoulders to
be used without any liability of said shoulders being split off in driving same, or
from the jolting of the vehicle; in fine, the spokes are bound firmly in and to the
hub, and the hub also is preserved from all danger of splitting.
The invention consists in the combination with a wooden hub, mortised in the
usual way, of a plain thin metallic band surrounding the bub, and provided with
mortises to match those in the hub, but larger than the latter, and bevelled on
their inner sides. The tenons of the spokes are driven into the mortises in the
wooden hub through the larger mortises in the metallic band, and the shoulders of
said spokes thus bear upon ledges formed by the peculiar manner in which the
metallic band fits the wooden hub; the bevelled inner edges of the mortises in said
metallic band forming seats for the spokes.
For more complete comprehension of the invention, reference must be had to
the annexed drawing in which similar letters of reference indicate like parts, and
where
Fig. 1 is a side elevation of hub with metallic band in place, but without spokes;
Fig 2 a cross section of same on line XX; Fig. 3 a longitudinal section with
spokes in place, and Fig. a detail of spoke.
In these drawings, the hub and metallic band are constructed with " dodging "
mortises, but it will be understood that the invention is equally applicable to hubs
in which the mortises are in a line with each other; the invention, however, has
particularly beneficial results when used with "dodging" mortises.
A is the wooden hub, turned in the usual or any approved way, and provided
with mortises B B for the spokes. As shown in Fig, 1 this hub is slightly conical,
or bevilled from inside to outside but this form is not absolutely necessary.
Over the wooden hub is slipped a circumferential metallic band C of just sufficient
size or diameter to slide easily into place. This band C is provided with oblong
slots or mortises c c one for each mortise in the hub A, but these slots c c are some-
what larger than the mortises B B, so that when the band C is in place, ledges a a
will appear on the hub at each side of mortises. The inner edges of the slots or
mortises c c are bevelled as shown particularly in fig. 2 and 3.
In Fig. 4 I have shewn a detail of the ordinary plain spoke D, but with its
shoulders D¹ D' slightly bevelled as shown at d d just above its tenon E.
When the spokes D are driven into the hub, the tenons E as usual, fit into the

page_text: mortises B B, but their shoulders D' D¹ rest on the ledges a a, and the bevelled
edges d d fit tightly against the bevelled edge of mortises in the metallic band C
which thus form seats for the same.
When the spokes D are all driven into their mortises, the wooden hub A
becomes swollen so as to make the circumferential metallic band C fit it very
tightly, and this band being very thin, it has no clumsy or unsightly appearance
when the wheel is' finished.
It will be seen that by this invention; the spokes'D' are so bound in the hub A
and its band C, that there will be no chance of the tenons E breaking off as they
do at present just below the shoulder's D¹, all strain at that point being removed,
and the edges of these shoulders being bevelled and bound inside the metallic
band, and the shoulders themselves directly on material of just equal resistance
to themselves, there is no possibility of the shoulders being split off by the
concussion of the vehicle, or by being driven in too hard while the wheel is being
constructed.
It is known that hubs have been made of wood and bands of metal slipped
over same at their ends; also that metal bands with upright flanges between
which the spokes are held by rivets or bolts, have been used on wooden hubs';
but none of these devices embodies the features peculiar to this invention,
inasmuch as that the specially desired method of "dodging "the mortises and spokes,
cannot be carried out in the latter case without rendering the hub very unsightly;
and further, although in the former case where a plain mortised band is' used, the
ordinary spoke herein shown' can be employed, no provision is made to allow the
spoke' shoulders to bear on the wooden hub which is absolutely necessary to prevent
their breaking sooner or later; and the tenous are in all cases bound to break off
at their weakest points.
What I claim and desire to secure by Letters Patent, is as follows:
1. The hub herein described, consisting essentially of the wooden inner hub A
having mortises B B, and with circumferential metallic band C, provided withi
mortises c c, one for each of the mortises B B, but larger than the same, so as to
form ledges a a on the wooden hub at each mortise for the spokes to bear upon,
substantially as described.
2. The combination with the metal band C provided with mortises c c having
bevelled sides, of the spokes D, constructed as described with bevelled shoulders d d
substantially as, and for the purpose specified.

In-witness whereof, I, the said Henri Adrien Bonneville, have hereunto set my
hand and seal, this
