ALFRED STANLEY (Surgeon) Coventry Road Small Heath Birmingham England do
hereby declare the nature of this invention to be as follows:-
The nature of invention is as follows:-
.. A circular or oval disc
in or more in. thickness size or shape immaterial, with
cupped centre. The disc may be made of any organic substance, india rubber,
leather, or any suitable material. The whole of the disc is covered with any
adhesive suitable cement. The disc must be first moistened, and a little suitable
cement poured into the central cup of disc. The disc to be applied, with concavity
over the puncture, or inner tube. The inner tube to be at once inflated.
What I claim is, a thickened disc, cupped in the centre, the action of which is,
that when the inner tube is inflated the resistance of the outer tube or tyre forces
the cement from the cup of disc directly into the puncture, & produces a perfect
repair. No time is lost, no necessity to wait until cement is dry and is the means of
saving the rider from the necessity of walking his cycle in some cases many miles!
This patent of course applies to tyres where an inner tube is in use.
ALFRED STANLEY.
Improvements in Means used in the Repair of Cycle and like
Pneumatic Tyres.
I, ALFRED STANLEY of "Glendale" Coventry Road, Small Heath, Birmingham,
Gentleman, 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 has reference to a process for quickly & perfectly repairing
punctures in pneumatic tyres of the wheels of bicycles & tricycles and all other
velocipedes & road carriages of any description, and this invention consists of the
herein described improved means for repairing the punctures with the least trouble
and the greatest perfection. In describing my invention I will refer to the
accompanying drawings on which
Fig. 1 shews the outer or convex side of the disc.
Fig. 2 shews the inner or concave side of the disc.

page_text: Fig. 3 shews & cross section of the disc.
Fig. 4 shews the disc placed in position over the puncture on the inner tube.
Fig. 5 shews the disc in position with inner tube nearly fully inflated.
Fig. 6 shews the disc in position & the inner tube fully inflated, & the cement
pressed through puncture of inner tube.
The letters of reference placed on the figures indicate the same parts on all the
figures.
In carrying out this invention I do not confine myself to the material used for the
disc, as the nature of tyre may change from time to time but for the sake of making
everything plain and to simplify this specification, I will describe the disc as made
of vulcanised rubber. The disc may be made in various sizes & shapes.
I will in describing my disc, make it in. in diameter, with a concavity in the
centre, as seen in Fig. 2 A din. in diameter, and as seen in Fig. 3 A in. in depth.
The disc being pressed into this shape, with its concavity on the one side, there is
an equal convexity on the other or outer side as seen in Fig. 1 B.
The disc when seen in section presents the appearance as seen in Fig. 3, shewing A
the concavity or inner side, B the convexity or outer side, & C the margin of disc.
The disc is coated with some suitable adhesive cement on both sides ready for use, &
simply needs moistening before applying, with the concave surface over the puncture
on inner tube, or if preferred another coat of cement may be brushed over the disc.
A little cement must be put intothe concavity Fig. 2 A before placing the disc in position,
prior to inflating the inner tube as shewn in Fig. 4 & as seen in section Fig. 5.
The inner tube Fig. 5 is seen to be partly inflated. In Fig. 6 the inner tube is
seen to be fully inflated and so presses the disc as to cause its convexity &
concavity to disappear, forcing the cement through the puncture & by this means
thoroughly sealing it, the cement being forced into the puncture by the resistance
of the outer tube or tyre when full inflation has taken place, and the appearance of
the inner side of inner tube where the cement has entered is as shewn in Fig. 6 D.
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. The herein described improved means for perfectly repairing a punctured
pneumatic tyre and by this means preventing the escape of air at the place of
puncture.
A disc for this purpose as shewn in Figs. 1, 2 and 3, cupped in the centre with
a concavity about in. in depth as before described, made of any organic material,
and coated with any suitable soluble cement
The margin of disc is immaterial.
I claim the cupped or concavo-convex disc for the purpose as described.
