PROVISIONAL SPECIFICATION.
Improvements relating to Pumps suitable for Cycles and the like.
We, Sir HENRY AARON ISAACS, Knight, of Maybourne, Laurie Park, Sydenham,
in the County of Surrey, and GEORGE ALLEN, of 51, Milton Street, in the City of
London, Manufacturers Agent, do hereby declare the nature of this invention
to be as follows:-
The object of this invention is to give compactness to the pump when out
of use.
The handle is in the form of a slotted tube the pump rod being pivotted to it
on the inside at about the middle of its length and protruding through the slot
when the pump is in use.
When the pump is out of use the handle is turned through a right angle and
forms a cap fitting onto the pump barrel the rod lying axially within it.
The foot rests, if such be employed, are hinged to the end of a stem projecting
from and in a line with the other end of the barrel. When the pump is in use
the rests are turned at right angles to the stem against a button or cap at its end.
When the pump is out of use the rests are turned down against the stem and are
covered by a tube sliding on the barrel and fitting against the cap at the end of
the stem. This tube has in it two holes which respectively come above and
uncover the socket for the air pipe when the tube is in its two extreme positions,
thus enabling the foot rests to be used or not at pleasure.

COMPLETE SPECIFICATION.
Improvements relating to Pumps suitable for Cycles and the like.
We, Sir HENRY AARON ISAACS, Knight, of Maybourne, Laurie Park, Sydenham,
in the County of Surrey, and GEORGE ALLEN, of 51, Milton Street, in the City of
London, Manufacturers' Agent, 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 improvements in and relating to pumps suitable for
cycles and the like, the object of the invention being to provide a pump that shall
be compact when out of use, and easily transformable into working condition
when so required.
In carrying out this invention the handle is made in the form of a slotted tube,
to which the pump rod is pivotted on the inside at about the middle of its length,

page_text: the handle being turned at right angles to the rod, when in use, the said rod
protruding through the slot.
When the pump is out of use the handle is turned so as to be parallel to the
length of the rod and forms a cap fitting on to the pump barrel the rod lying
axially within it.
At the other end of the pump barrel are foot rests (if such be employed) which
are hinged to the end of a stem projecting from and in a line with the end of the
barrel. When the pump is in use these said rests are turned at right angles to
the stem against a button or cap at its end. When the pump is out of use the
rests are turned down against the stem and are covered by a tube sliding on the
barrel and fitting against the cap at the end of the stem. This said tube has in
it two holes, which respectively come above and uncover the socket for the air
pipe when the tube is in its two extreme positions, thus enabling the foot rests to
be used or not at pleasure.
for usc.
In order that this invention may be readily understood reference is made to
the accompanying drawings in which Fig. 1 represents the pump with the acces-
sories hereinbefore described in a closed and compact form when not in use. Fig. 2,
represents the pump with the pivotted handle and the foot rest in position ready
Fig.3 is a view of the same seen at right angle to Fig. 2 and Fig. 4,
is a sectional end view of the foot rest in working position. In these several
views the same letters refer to the same parts. A being the body of the pump
barrel, B the rod or pump spindle, C the tube for connecting the pump to the
cycle or like machine, by screwing the same into the hole D of the pump barrel,
E is the handle pivotted at F to the pump rod, and when in working position
is at right angles to the rod as shewn at G but when not required slides over
the pump barrel as shewn at H. The foot rests are hinged at II to the end of
the stem and when in use are opened out at right angles to the line of the barrel
and stem but when not in use are folded up against the stem K and are covered
by the sliding tube L. MM are the two holes in said sliding tube so arranged
as that one or the other shall be over the hole D of the pump barrel, whether
the sliding tube aforesaid is covering the feet folded up against the stem or drawn
back over the pump barrel to allow the feet to be opened.
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 pumps used for cycles and the like the provision of a pivotted handle
attached to the pump rod adapted to slide over the pump barrel, a foot rest made
to fold up against the stem of the pump barrel and a sliding tube covering said
foot rest when not in use, all substantially as and for the purpose herein set
forth and described and illustrated by the accompanying drawings.
2. The application of this invention to any form or kind of pump used for
cycles and the like, substantially as and for the purpose herein set forth and
described and illustrated by the accompanying drawings.
