PROVISIONAL SPECIFICATION.
Improvements in Velocipedes, Bicycles, and Tricycles.
I, JAMES ROBSON of 34, Queenshead Road, Handsworth, in the County of
Stafford, Mechanical Engineer, do hereby declare the nature of this invention to
be as follows:-
My invention of improvements in velocipedes, bicycles, & tricycles, consists in
utilizing the metallic, tubular framing of such machines, for forming the barrel of
the air compressing pump, used in. charging the hollow, elastic, wheel tyres with
air, instead of using a detached or separate pump.
In one arrangement in a safety bicycle I use the straight tube connecting the
top and bottom frame stays for the barrel of the pump, which pump barrel is closed
at the bottom and has suction and delivery valves and a nozzle, to which nozzle,
one end of a flexible tube is attached and the other end of the tube is attached
to the inlet nozzle of the wheel tyre; when charging the tyre with air.
This flexible tube, when detached, may be stored away in the pump barrel, or in
one of the other tubes of the bicycle framing.
In the pump works a piston and rod for forcing the air; the top of the pump
barrel tube may be used for holding the shifting support rod of the saddle: this
saddle rod may be used as a pump handle, by screwing it on to the pump
piston rod.
I sometimes use the tubes, of the machine frame, for storing oil for lubricating
the machine, or burning in its lamp. A tube of the machine may also be used as a
receptacle for a separate hand pump; when such is used for inflating the wheel
tyres.

COMPLETE SPECIFICATION.
Improvements in Velocipedes, Bicycles, and Tricycles.
I, JAMES ROBSON, of 34, Queenshead Road, Handsworth in the County of
Stafford Engineer, 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:—
My invention of improvements in velocipedes, bicycles, and tricycles, consists in
utilising the metallic tubular framing of such machines for forming the barrel of
the air compressing pump used in charging the hollow elastic wheel tyres with air,
instead of using a detached or separate pump.
In one arrangement in a safety bicycle I use the straight tube connecting the
top and bottom frame stays for the barrel of the pump which pump barrel is closed
at the bottom and has suction and delivery valves and a nozzle, to which nozzle
one end of a flexible tube is attached, and the other end of the tube is attached to
the inlet nozzle of the wheel tyre, when charging the tyre with air. This flexible
tube when detached may be stored away in the pump barrel, or in one of the other
tubes of the bicycle framing.
In the pump works a piston and rod for forcing the air, the top of the pump
barrel tube may be used for holding the shifting support rod of the saddle: this
saddle rod may be used as a pump handle by screwing it on to the pump piston rod,
or a separate handle may be used.
I sometimes use the tubes of the machine frame, for storing oil for lubricating

page_text: the machine, or for burning in its lamp. A tube of the machine may also be used
as a receptacle for a separate hand pump when such is used for inflating the
wheel tyres.
For the purpose of more fully showing how my invention is carried into practice,
reference is to be had to the accompanying drawings, forming part of this
Specification.
Figure A, represents the frame, saddle, and part of the wheels of a diamond
safety bicycle, in which I use the tube 1. as an air pump barrel, in which works an
ordinary leather cupped piston 2. having a tabular piston rod 3. with an internal
screw (or bayonet joint) 4. at its top to receive a screw 5 on the bottom of a handle
rod 6, the piston rod 3, can in the act of pumping be worked up and down through
the usual slit in the saddle 7. and the saddle tubular pillar 8. To effect this the
handle rod is drawn up and screwed into the top of the piston rod leaving the top
of the rod 6. above the saddle as shewn by the dotted lines so that it can be handled
in the act of pumping, a larger view of the piston rod top and handle rod is shewn
in Fig. B. wherein the same numerals refer to the same parts. The cupped piston
leather serves as the air inlet valve, and an outlet valve is provided at 9, which
may be a steel, or other ball working on a leather or other flexible seat, or it may
be a small rubber tube with a slit in its side, on the casing of this valve a flexible
tube 10 is screwed or otherwise coupled and its other end coupled to the inlet
ducts 11 on either of the wheels when it is desired to inflate the wheel tyres 12
with air.
Another modification is shown in the tube 13 wherein the piston and rod is shown
by the dotted lines and by a cross section in Fig. C, a pin 14 sliding in a slit 16 in
the
pump barrel connects the piston rod to a tubular handle 15, which slides on the
outside of the pump barrel, and by this means works the air pump rod and piston,
the outlet valve is at 17. to which the flexible tube 10 can be attached as in the
other arrangement.
Curved tubes may be used for the pump barrel as well as the straight ones
herein shown.
Any of the tubes as the one 18. can be used for storing the flexible tube 10 in
when not in use, it may be closed by a screw or hinged cap 19, or it may be used for
storing a separate pump when such is used.
Any of the tubes as at 20. can be used for storing oil in, by having an inlet screw
3.1.99
cap 21, and an outlet 22.
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. Using any of the tubes in velocipedes, bicycles, or tricycles, as a pump for
inflating the tyres with air, as described and shown herein or any modification
thereof for effecting the same purpose.
2. Using any of the tubes in velocipedes, bicycles, or tricycles, for storing the
flexible connecting tube, such store tubes having screw or hinged caps, or for storing
a separate pump when such is used, as herein described and shown.
3 Using any of the tubes in a velocipede, bicycle, or tricycle, for storing oil in,
as herein described and shown, or any modification thereof.
