Improvements in Bicycle and other Tires.
1, HENRY HARRIS LAKE, of the Firm of Haseltine Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex, do hereby declare the
nature of this invention to be as follows:-
The object of my invention is to produce a tire combining proper strength with
extreme lightness, and my invention consists mainly in the combination of a
troughed rim with a split sheath having a shoulder along each of its four margins,
a pair of hoops, a clamp engaging the hoops and an inflatable tube, all as more
specifically set forth below.
The split sheath or cover is formed with marginal shoulders, two of the latter
being on the inner margins, and two on the outer margins of the sheath. Hoops
preferably of a fine quality of steel are provided for holding the tire in place. A
transverse clamp is provided formed with shoulders and a valve stem projects into
the inflatable tube.
When these parts are assembled, the outer marginal shoulders of the sheath or
cover engage the sides and bottom of rim, the hoops clamping the edges of
sheath against the rim and resting in the angles formed by the inner shoulders
with the adjacent inner surface of the sheath. The shoulders or fingers of the
clamp engage the hoops and bind them in their resting places, the shoulders
serving as abutments to prevent closer lateral approach of the hoops. The clamp
is preferably held in place by the head of valve stem which receives a nut which
bears against the inner periphery of rim. Ordinarily I use but one clamp but in
case a plurality of clamps desired, ordinary bolts and nuts may be used to retain
them in place. The clamp is formed with a tubular projection which is between
the opposed edges of the sheath but does not bottom on the rim. The use of such
a form of clamp prevents all possibility of the sheath's creeping, but is not
absolutely necessary to this end. The hoops are forced into place by exterior
pressure on the sheath after the shoulders are located in the troughed rim.
By this construction, an exceedingly strong and light tire is produced, the
sheath of which is readily removed and replaced for repairing the air-tube.
The clamp may be dispensed with and the sheath held in place by the hoops.
Dated this 24th day of April 1893.

COMPLETE SPECIFICATION.
Improvements in Bicycle and other Tires.
I, HENRY HARRIS LAKE, of the Firm of Haseltine Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex, 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 :-
The object of my invention is to produce a tire combining proper strength with

page_text: °
extreme lightness, and my invention consists mainly in the combination of a
troughed-shaped rim with a split sheath having a shoulder along each of its four
margins, a pair of hoops, a clamp engaging the hoops and an inflatable tube, as
hereinafter described.
In the accompanying drawing,
Figure 1 is a side view of a portion of a rim and tire embodying this inven
tion, a part being broken away for greater clearness.
Figure 2 is a cross-sectional view on line 2-2 of Figure 1
and
Figure 3 is a partial cross-sectional view at line 3-3 of Figure 1.
Figure 4 is a cross-sectional view illustrating positions of the different elements
of the new tire while the same is being put in place on the rim, and
Figure 5 is a modification of the said invention.
In the various figures, 1 indicates the troughed-shaped rim, and 2 the split
sheath or cover formed with marginal shoulders 3, 4, 5 and 6, the shoulders 3 and 5
being on the inner margins, and the shoulders 4 and 6-on the outer margins of the
sheath. Hoops 7 and 8, preferably of a fine quality of steel are provided for
holding the tire in place. 9 is a transverse clamp formed with shoulders 10; 11 is
a valve stem projecting into the inflatable tube 13.
When these parts are assembled, the outer marginal shoulders 4 and 6 of the
sheath or cover engage the sides and bottom of rim 1, the hoops 7 and 8 clamping
the edges of sheath 2 against the rim and resting in the angles formed by the inner
shoulders 3 and 5 respectively, with the adjacent inner surface of the sheath.
The shoulders or fingers 10, 10 of the clamp 9 engage the hoops and bind them
in their resting places, the shoulders 3 and 5 serving as abutments to prevent
closer lateral approach of the hoops. The clamp 9 is preferably held in place
by the head of valve stem 11, which receives a nut bearing against the inner
periphery of rim 1. Ordinarily I use but one clamp 9, but in case a plurality of
clamps 9 is desired, ordinary bolts and nuts may be used to retain them in place.
The clamp 9, is formed with a tubular projection 12, which is between the opposed
edges of the sheath but does not bottom on the rim. The use of such a form
of clamp prevents all possibility of the sheath's creeping, but is not absolutely
necessary to this end.
In Figure 4, I have illustrated the parts in the position they occupy when being
assembled, the hoops being forced into place by exterior pressure on the sheath
after the shoulders are located in the troughed rim.
By this construction, an exceedingly strong and light tire is produced, the sheath
of which is readily removed and replaced for repairing the air-tube.
In Figure 5, the clamp 9 is dispensed with and the sheath held in place by the
hoops, 7 and 8.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is :-
First. In a tire, the herein described combination of a troughed-shaped rim, a
sheath, an inner inflatable tube, a pair of interior hoops, a transverse clamp and
means for holding it in place, the sheath being formed with shoulders along each
margin, the outer shoulders engaging the rim, the inner shoulders being engaged
by the hoops, and the transverse clamp holding the hoops against the inner shoulders,
all substantially as and for the purpose set forth.
Second. In a tire, the combination of a troughed-shaped rim, a sheath and an
interior expansible tube with a pair of hoops intermediate the sheath and expansible
tube, the sheath being provided with a shoulder along each margin, the outer
shoulders lying in the rim, and the inner shoulders forming abutments to prevent
the hoops moving laterally, all substantially as and for the purpose set forth.
Third. In a tire, the combination of a troughed-shaped rim and a split sheath
with a pair of hoops, the sheath being formed with outer marginal shoulders

page_text: engaging the flanges of the rim, and with inner marginal shoulders forming
abutments for the hoops, all substantially as and for the purpose set forth.
