I, ALEXANDER FOSCOE DONNELLY, of 27, High Street, Serampore, in the
Province of Bengal, British India, Gentleman, do hereby declare the nature of
this invention to be as follows:-
(1) A portable apparatus for patching-by thumb screw pressure-pneumatic
tyres for the wheels of bicycles tricycles, and other vehicles.
(2) It consists broadly of an iron, or other durable material, hinge fitted with
(1) a pair of movable wooden flush-surface slides or dies, and (2) a pair of
movable wooden male and female slides or dies, and a thumb-screw.
(3) The following describes the method of using the invention. On a slit
or tear being observed in an outer cover or tyre such cover or tyre is taken off
the wheel, and the torn part placed between the male and female dies fitted on
the hinge. A piece of suitable material-sufficient to cover the tear-duly
treated with an adhesive composition is then placed on the tear, and pressure
applied by the thumb screw until such time as the material used in patching
has obtained a firm hold of the substance of the tyre by the drying of the adhesive
substance. This method secures a smooth and durable patch. The same method
applies in patching a rent or tear in the inner tube the only difference being the
substitution of the flush surface dies, instead of the male and female dies, in the
hinge of the apparatus.
(4) Its objects are easy, secure, and satisfactory patching either in the shop,
at home, or on the road, of outer covers and inner tubes of bicycles and the like.
And having now described the nature of my invention I would have it under-
stood that I do not confine myself to the particular arrangement herein described
which may be varied without departing from the essence of the invention.

Fortable Apparatus for Patching Pneumatic Tyres for the Wheels
of Bicycles, Tricycles, and other Vehicles.
I, ALEXANDER FOSCOE DONNELLY, of 27, High Street, Serampore, in the
Province of Bengal, British India, 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:
1. The invention is of a portable apparatus for patching-by thumb-screw
pressure-pneumatic tyres for wheels of bicycles, tricycles, and other vehicles.

page_text: It consists of an iron, or other durable material, hinge fitted with (I) a pair of
movable wooden, or other durable material, flush surface slides or dies and
(II) a pair of movable wooden, or other durable matérial, male and female slides
or dies, and (III) a thumb-screw.
2. The following describes the manner of using the invention:-On a slit or
tear being observed in an outer cover or tyre such cover or tyre is. taken off the
wheel, and the torn part placed between the male & female dies fitted on the
hinge. A piece of suitable material sufficient. to cover the tear-duly treated with
an adhesive composition, is then placed on the tear, and pressure applied by the
thumb-screw until such time as the material used in patching has obtained a
firm hold of the substance of the tyre by the drying of the adhesive substance.
This method screwes a smooth and durable patch.
The same method applies in patching a rent or tear in the inner tube the only
difference being the substitution of the flush surface dies, instead of the male
and female dies in the hinge of the apparatus. These objects are obtained by
the devices illustrated in the accompanying drawings-
Fig. 1. Sheet No. 1 is the upper and bottom view of Fig. 2, Sheet 1.
Fig. 2. Sheet No. 1 is the sectional view of the male and female dies.
Fig. 3. Sheet No. 2 is the top view of the female die..
Fig. 4. Sheet No. 2 is the top view of the male die.
Fig. 5. Sheet No..2 is the sectional view of the female die.
Fig. 6. Sheet No. 2 is the sectional view of the male die.
Fig. 7. Sheet No. 3 is one part of the iron or durable material hinge with a
flush die.
Fig. 8. Sheet No. 3 is the other view of the iron or durable material hinge
with a flush die.
Fig. 9. Sheet No. 3 is a complete view of the hinge without the flush dies, but
with the thumb-screw and bolt attached.
Fig. 10. Sheet No. 4 is the top view of the hinge.
Fig. 11. Sheet No. 4 is the bottom view of the hinge shewing a die in position.
Fig. 12. Sheet No. 4 is a separate view of the die.
3. The advantages of the invention are
(I). That the apparatus being constructed of durable material admits of
sufficient rigidity of form and contrivance of its parts to successfully and
readily exert the necessary and even pressure on any part required in
the patching of rubber tubes and tyres.
II. That the apparatus being of a reasonable size and weight admits of its
being used as a handy tool or instrument in the workshop or carried on
a bicycle or other vehicle without inconvenience for similar use on the
road, so that in the case of accident or mishap en route to either tube or
tyre the contrivance will be immediately available to a rider for its work.
III. That the apparatus has been a long felt want, is entirely new, and
fulfills, its purpose with the maximum of durability, trueness, and expedi-
tion, and the minimum of unstability, trouble and expense.
And having now described the nature, manner, of working, and advantages
of my invention, I would have it understood that I do not confine myself to the
particular arrangement herein described which may be varied without departing
from the essence of the invention, but what I claim as novel and desire to
protect is:
The novel apparatus substantially described and illustrated for the purpose
of patching pneumatic tubes and tyres of bicycles tricycles and other vehicles.
