page_text: I, PERCY GEIKIE DONALD, of 9 Canonbury Lane, in the County of London, Clerk,
do hereby declare the nature of this invention to be as follows:-
The object of the present invention is to provide an efficient and comfortable handle
for pumps which can be folded and stowed away in the interior of the pump when not
in use, and a simple means of firmly holding the end of the inflating nozzle.
My invention is applicable to pumps having a tubular rod. The exterior end of
this tube is fitted with a bush which is screw threaded and into which screws the
enlarged end of a short rod. At the outer end of this latter is pivoted a cross piece
made of any suitable material provided with a groove or slot on one side of the pivot
pin so that the said cross piece may be turned into line with the short rod aforesaid.
When in use the enlarged end of the short rod is screwed into the end of the pump
rod and the cross piece is turned at right angles to the short rod. When it is desired
to stow the pump away the cross piece is turned into a line with the short rod and
they are rotated, thereby screwing the enlarged portion of the short rod through and
clear of the screwed portion of the pump rod. The cross piece will now slip through
the screwed portion of the pump rod as it is of smaller diameter.
The exterior end of the cross piece may have an enlargement which is screw
threaded and may be screwed into the end of the pump rod thus holding the parts
firmly within the rod and preventing any rattling, or a spring catch or other suitable
means may be employed for the same purpose.
In some cases instead of employing a screw thread in the end of the pump rod I
may cut a bayonet groove and make the other parts in a suitable manner for use
therewith.
In order to retain the inflating tube in a firm position on the pump when the latter
is being carried on the machine I attach to the end of the pump barrel, a short tube
or a small piece of spring metal or other material of C shape into which the end of
the inflating tube is inserted.

page_text: what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
The object of the present invention is, firstly, to provide an efficient and comfort-
able handle for pumps which can be stowed away in the interior of the pump when
not in use, and secondly, to provide a simple means of firmly holding the outer end
of the inflating nozzle when the pump is being carried on the machine.
Fig. 1 of the accompanying drawings shows a pump constructed according to my
invention, partly in section, the handle being in position for use and the inflating
nozzle being in the position it would assume when the pump is carried on the
machine.
Fig. 2 is a view of the handle end of the same pump shown at right angles to
Fig. 1.
Fig. 3 is a sectional view of part of the pump showing the handle stowed away in
the interior of the pump rod.
Figs. 4 and 5 are elevations drawn at right angles to each other of the spring clip
for holding the inflating nozzle.
Fig. 6 is a side view of a somewhat similar form of spring clip for holding the
inflating nozzle combined with a clip for attaching the pump to a tube of a velocipede
and Fig. 7 is a front view of the same.
In all the figures like parts are indicated by similar letters of reference.
The first part of my invention is applicable to pumps having a tubular pump rod.
a is the pump barrel, b is the tubular pump rod, which is provided with a screw
thread at its exterior end, as shown in Figs. 1 and 3. This screw thread projects
from the interior surface of the pump rod b and is therefore preferably cut in a bush
which is inserted in the end of the pump rod.
The handle c is pivoted at or near its centre at c¹ and is provided with a screw
thread c² at one end to screw into the screw thread in the interior of the pump rod b.
The handle c is formed with a slot c³ from the pivot c¹ to the opposite end to that
having the screw thread c², which enables the same to be turned on its pivot c' either
into line with, or at right angles to, the pump barrel. The pivot c connects the
handle c to a rod d, which has an enlargement d¹ fitting loosely the interior of the
pump rod b.
Part of this said enlargement 2 is screw-threaded to fit the screw
thread in the interior of the pump rod b.
When in use, as shown at Fig. 1, the part d² is screwed into the end of the pump
rod b, and the handle c is turned at right angles to the rod d.
When it is desired to stow the handle c in the interior of the pump rod b, it is
turned into line with the rod d, which latter then passes through the slot c³ and
occupies the interior of the handle c, and the handle c and rod d are then rotated,
thereby screwing the portion d² through and clear of the screwed portion of the
pump rod. The handle or cross piece c will now slip through the screwed portion of
the pump rod as it is of smaller diameter, and the screw threaded portion c² of the
handle c is then screwed into the end of the pump rod b, thus holding the parts
firmly together and preventing any rattling.
It will be understood that I can dispense with the screw thread c² and employ
a spring catch to secure the handle c to the pump rod when not in use.
In some cases instead of employing a screw thread in the interior of the pump
rod, I may cut bayonet grooves in the same and provide the rod d and the handle c
with projections to fit said bayonet grooves.
At Figs. 4 and 5 I have shown a spring clip e for holding the end of the inflating
nozzle when desired. This spring clip e may be attached to the pump a by means
of a spring clip e¹ or by other suitable means. In some cases the portion e is made
in the form of a complete tube and the end of the inflating nozzle f is passed
therethrough.
The spring clip shown at Figs. 4 and 5 is made of vulcanite or celluloid but it
may be made of any suitable material. The clip shown at Figs. 6 and 7 is made of
metal and has a small rubber ring e² to prevent the enamel being scratched on the
machine by the clip g.

page_text: 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 a pump for inflating pneumatic tyres having a hollow pump rod, a pivoted
handle capable of being turned into line with said pump rod and stowed away
therein, substantially as herein shown and described.
2. In a pump for inflating pneumatic tyres having a hollow pump rod b, a rod d,
to which latter is pivoted a handle c capable of being turned into line with the
rod d, and means for connecting and retaining the rod d and handle c with the
pump rod b, substantially as herein shown and described.
3. In a pump for inflating pneumatic tyres, the combination of a hollow pump
rod b, a plug or enlargement d¹ provided with means for attaching it to said hollow
rod b, a rod d carrying such enlargement d¹ and pivoted to a handle c, a slot c³ in
said handle, and means for attaching the latter to the hollow pump rod b,
substantially as herein shown and described.
4. A pump for pneumatic tyres having a spring clip to retain the inflating nozzle
when not in use, substantially as herein shown and described and for the purpose
stated.
5. A pump for pneumatic tyres having a short tube to receive the end of the
inflating nozzle, substantially as herein described and for the purpose stated.
6. In a pump for inflating pneumatic tyres, the combination of a hollow pump
rod b having at its end an internal screw thread, an enlargement or plug d' having a
screw-threaded portion 2, a rod d, a pivot c¹, a handle c having a slot c³ and a screw-
threaded portion c², substantially as herein shown and described.
