PROVISIONAL SPECIFICATION.
Improved Pneumatic Vehicle Tyre, and Means for Attachment to
the Rim.
I, ALBERT EDWARD SPANGLER of 623 Catherine Street, Syracuse, in the
County of Onondaga, State of New York, United States of America, Engraver, do
hereby declare the nature of this invention to be as follows:-
--
This invention relates to vehicle wheels, and the tyres therefor, and more
particularly to the means for securing tyres thereon.
My object is to produce a tyre for a vehicle wheel, which may be locked into the
rim, either mechanically or automatically by the inflation of the pneumatic tube,
and to that end my invention consists in the several new and novel combinations of
parts hereinafter described.
It is constructed as follows;-
I use an inner pneumatic sack of any ordinary construction.
1 employ an outer shoe, casing or tyre, enclosing the sack, and having its lateral
edges enlarged to fit into side troughs of the rim which has its outer face adapted
to receive two parallel metallic plates, and has its outer edge bent to form pockets
for the reception of the edges of the tyre.
The said parallel plates are so mounted upon the upper face of the rim, as to
allow them to move laterally, so as to partially enclose the mouth of the pocket in
the rim, after the enlarged ends of the shoe have been inserted.
I mount a cam upon a shank passing through the rim, and so that it is interposed
between the adjacent edges of the plates, and by which these plates are forced apart
so as to partially enclose the mouth of the recess in the rim.
A cap is secured upon the upper face of the cam, overlapping the adjacent edges
of the said plates, for the purpose of keeping the cam faces always in engagement
with the adjacent edges of the plates.
I do not limit myself to any particular way of operating this cam, as it will be
evident that it may be done in various ways.
A flexible cover, made of rubber or any other material desired, is interposed
between the upper face of the plates and the pneumatic sack, for the purpose of
preventing the pneumatic sack from coming into frictional contact with said
plates.
I may use also another means for separating the plates automatically with the
inflation of the pneumatic sack.
may use a piece of rubber webbing, or other preferably elastic material, having
the said plates secured thereon in any ordinary manner, preferably however,
vulcanized therein, the web forming an elastic bulge or ridge between them; and
the plates are thus forced apart by the elasticity of the said plate attachment and
when the pneumatic sack is inflated, the said attachment webbing will be forced out
into a horizontal plane or slightly depressed position thereby securely locking the
edges of the shoe within the rim."

Improved Pneumatic Vehicle Tyre, and Means for Attachment to
the Rim.
1, ALBERT EDWARD SPANGLER, of 623 Catherine Street, Syracuse, in the
County of Onondaga, State of New York, United States of America, Engraver, 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 wheels and the tires therefor, and more
particularly to the means for securing tires thereon.
My object is to produce a tire for a vehicle wheel which may be locked into the
rim, either mechanically or automatically by the inflation of the pneumatic tube;
and to that end my invention consists in the several new and novel combination of
parts hereinafter described and which are specifically set forth in the claims
hereunto annexed.
It is constructed as follows, reference being had to the accompanying drawings,
in which,
Fig. 1, is a transverse section of the rim and tire complete, inflated.
Fig. 2, is a transverse section of the rim and shoe showing the continuous bands,
mechanically expanded.
Fig. 3, is a similar view thereof with the bands contracted.
Fig. 4, is a top plan view of a section of bands expanded.
Fig. 5, is a similar view with the bands contracted.
Fig. 6, is a cross section of a rim and bands, showing their resilient connection
contracted.
Fig. 7, is a similar view with the bands expanded.
Fig. 8, is a section of the continuous bands having a resilient connection.
A. is the pneumatic sack of any ordinary construction.
B. is the outer shoe or casing enclosing the sack, and having its lateral edges a
enlarged substantially as shown.
C. is the rim of the wheel having its outer face adapted to receive the sub-
stantially parallel, continuous, metallic plates or bands 6 and having its outer edges
constructed to form pockets c for the reception of the edges a of the tire. The
parallel plates or bands are continuous and so mounted upon the upper or outer
face of the rim C as to allow them to move laterally, so as to partially enclose the
mouth of the pocket c in the rim, after the enlarged ends of the shoe have been
inserted.
D. is a piece of rubber webbing or other preferably elastic material having the
continuous plates or bands b secured therein in any ordinary manner, preferably,
however, vulcanized therein, said bands being adapted to be forced apart by the
elasticity of the webbing, which form a resilient connection, thereby allowing the
plates or bands to partially enclose the top opening of the pocket c.
It will be observed that when the pneumatic sack is inflated that portion of the
webbing between the plates will assume the position shown in Figs. 1 & 7, thereby
securely forcing the plates over the top of the pocket and preventing the lateral
edges of the shoe from being withdrawn.
It will be observed that when it is desired to remove the shoe, the pneumatic
sack may be deflated, the plate pushed inwardly until it assumes the position shown
in Fig. 6, when one of the lateral edges may be withdrawn from the pocket, and
returned again to its position in the rim, and the sack again inflated.
In Figs. 2 & I show a mechanical means of expanding the continuous bands,
E being a cam mounted upon a shank passing through the rim, and is interposed
between the adjacent edges of the plates, and by which these plates are forced

page_text: apart so as to partially enclose the mouth of the recess in the rim as shown in
Fig. 2.
d is a cap secured upon the upper face of the cam and overlapping the adjacent
edges of the band 6 for the purpose of keeping the cam face always in engagement
with the adjacent edges of the plate.
I do not limit myself to any particular way of separating these bands, as it will
be evident that it may be done in various ways.
e is a flexible cover made of rubber or any other material desired, and is
interposed between the upper face of the bands and the pneumatic sack, for the
purpose of preventing the pneumatic sack from coming into frictional contact with
said plates.
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. In a tire, continuous flat bands connected together and adapted to be
contracted or expanded in the plane of their faces.
2. In a tire, continuous flat bands having a resilient connection between them
and adapted to be contracted or expanded in plane of their faces.
3. In a tire, the herein described continuous plates or bands secured together,
yielding laterally, in the plane of their faces.
4. A pneumatic tire comprising a sack, a shoe having enlarged edges, a rim
having pockets for receiving said edges; continuous plates or bands mounted upon
said rim, and yielding laterally in the plane of their faces, and means for limiting
their lateral movement.
5. A pneumatic tire comprising a sack, a shoe having enlarged edges, a rim
having pockets for receiving said edges, a web having continuous plates or bands
secured within or to its lateral edges, as set forth.
6. A pneumatic tire comprising a sack, a shoe having enlarged edges, a rim
having pockets for receiving said edges, continuous plates or bands mounted upon
said rim and means for forcing them apart in the plane of their faces and retaining
them in this position.
7. A pneumatic tire comprising a shoe having thickened edges a rim concaved to
receive said edges, and a lock comprising flat bands and a flexible connection
between them, in combination with a pneumatic sack within said shoe, adapted to
engage with said connection and spread said bands apart in the plane of their
faces.
8. A pneumatic tire comprising a sack, a shoe having enlarged edges, a rim
having pockets for receiving said edges, plates mounted upon said rim, cams
engaging with the adjacent faces of said plates, and adapted to force them apart.
9. A pneumatic tire comprising a sack, a shoe having enlarged edges, a rim
having pockets for receiving said edges, plates mounted upon said rim, cams
engaging with the adjacent faces of said plates and adapted to force them apart for
the purpose of locking the edges of the tire within the rim, and a cap upon said
cam for the purpose of keeping the edges thereof in engagement with the adjacent
edges of the plates.
10. In a tire, the herein described continuous plates secured together yielding
laterally as set forth.
