PROVISIONAL SPECIFICATION.
Improvements in Attaching Pneumatic Tyres to the Rims of Wheels.
I, FREDERICK RICHARD SIMMS, of Amberley House, 12, Norfolk Street, Strand,
in the County of London, Consulting Engineer, do hereby declare the nature
of this invention to be as follows:-
This invention relates to improvements in attaching pneumatic tyres to the
rims of wheels; the said improvements being more especially applicable to tyres
of the kind described in the Specification of my former Patent No. 29945%
According to the present invention 1 attach the outer covers of such tyres to
the lateral recesses in the rim by means of a number of clips which embrace
the lateral lugs upon the outer cover and are formed with projections adapted
to be passed into slots or the like in the recessed portions of the rim so as to
project therethrough, the said clips being then held in position in the rim
preferably by means of copper shackles or other pins or the like which are
passed through holes in the said projecting portions.
The clip which I advantageously employ is stamped from a sheet metal blank,
the said sheet metal blank being of suitable length and slit transversely through
about three quarters of its breadth, the portions thus severed being bent upwards
and downwards respectively so as to form two arms which embrace the lateral
lugs of the outer cover being held thereon by copper or other suitable rivets;
the unslit portion of the strip forms the projection which is passed through the
slot in the rim and is provided with the holes for receiving the copper shackles
or other pins or fastenings.
Tyres attached to the rims of wheels in the above described manner are rigidly
secured in place. Should it be necessary to remove the outer cover, however,
for example in the case of the inner tube of the tyre being punctured, this can
easily be effected by removing the copper pins or fastenings. It will be obvious
also that the tyre can be replaced with facility.

described and ascertained in and by; the following statement:-
This invention relates to improvenients in attaching pneumatic tyres to the
rims of wheels, the said improvements being more especially applicable to tyres
of the kind described in the Specification of my former Patent No. 29945%.
According to the present invention I attach the outer covers of such tyres to
the lateral recesses in the rim by means of a number of clips which embrace
the lateral lugs or flanges upon the outer cover and are formed with projections
adapted to be passed into slots or the like in the recessed portions of the rim so as
to project therethrough, the said clips being then held in position in the rim
preferably by means of copper shackles or other pins or the like which are
passed through holes in the said projecting portions.
In the accompanying drawing,—
Figure 1 is a transverse section of part of the rim and pneumatic tyre of a
wheel illustrating my improvements in attaching tyres to rims :
Figure 2 is a plan of a sheet metal blank from which the clips are formed:
Figure 3 is an elevation of the said clip formed from the blank shewn in
Figure 2; and
Figure 4 is a detached view of one of the copper pins or shackles whereby
the clips and tyre are held in position in the rim.
Figure 1, is the rim of the wheel, the inner tube or air chamber, e the
outer cover of the tyre and d one of the lateral flanges thereon.
e shews one of the clips which embrace the lateral flanges & upon the outer
cover; is the projection on the clip c which projection is adapted to be passed
through slots or the like in the recessed portion of, the rim so as to project
therethrough as shewn; is one of the copper shackles which are passed through
holes in the projecting portions f of the clips e in order to hold the latter in
position in the rim.
The clip which I advantageously employ is stamped from a sheet metal blank,
shewn at Figure 2, the said sheet metal blank being of suitable length and slit or
cut away transversely at i, i through about three quarters of its breadth, the por-
tions thus severed being bent upwards and downwards respectively so as to
form two arms, j, Figure 1, which embrace the lateral flanges d of the outer
cover, being held thereon by copper or other suitable rivets (one of which is
shewn at k) passed through the holes 1, 1, Figure 2, in the clip and through the
lateral flange d Figure 1; the unslit portion m, Figure 2, of the blank forms
the projection of Figures 1 and 3, which is passed through the slot in the
rim and is provided with the holes, for receiving the copper shackles
other pins or fastenings.
or
Tyres attached to the rims of wheels in the above described manner are rigidly
secured in place. Should it be necessary to remove the outer cover c, however,
for example, in the case of the inner tube of the tyre being punctured, this
can easily be effected by removing the copper pins or fastenings h. It will be
obvious also that the tyre can be replaced with facility.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
1. In pneumatic tyres of the kind referred to the described method of attach-
ing the outer cover to the rim, such method consisting in securing the lateral
flanges of the outer cover to the lateral recesses in the rim by means of a number
of clips embracing the said Hanges and having projections which are passed
through slots or the like in the recessed portions of the rim and receive
shackles, pins
or like fastening devices, substantially as set forth.
2. A clip for attaching pneumatic tyres to the rims of wheels the said clips
being made from a sheet metal blank stamped with holes near its end and
middle and divided transversely through a portion of its width, the two parts

page_text: thus formed being then bent so as to constitute arms adapted to embrace the
lateral flanges of the outer cover, and a projection adapted to be passed through
slots in the rim, substantially as set forth.
3. Wheel rims having pneumatic tyres secured thereto in the manner sub-
stantially as herein before described and illustrated in the accompanying drawing.
