Tyres and the like.
I, ARTHUR JAMES HENDERSON of 2 Lombard Court, in the City of London, Consulting
Engineer, do hereby declare the nature of this invention to be as follows:-
My invention relates to certain improvements in air pumps adapted for inflating
pneumatic tyres and such as are suitable for carrying on cycles and the like or for
inflating footballs and similar small air filled articles.
One form of pump or inflater constructed according to my invention is provided
with a cross-handle attached to the piston rod, such handle being arranged to fold
into line with the pump. The handle is of sheet metal and is cut away to enable it
to pass or to spring as desired over the body of the pump, and in this I form a
receptacle for sinall articles such as a tyre repairs outfit and provides it with a
removable cover. The cross-handle however I prefer to construct by pivoting it
centrally in a fork or crutch carried by the body of the pump, and I provide it with
the receptacle above described and with a stud having a spring or rubber ring at the
back of same so that it may engage with the crutch or the body of the pump and be
held in line with the pump when desired, or be readily turned across to form a
handle.
The pump has a folding portion or portions which is or are adapted to be held
down by the foot when pumping, and this foot or feet I form of bent wire the ends
of which are turned into a metal ring or rings in the base of the pump. When not
in use the wire is turned up and engages with a catch on the body of the pump.
The piston rod is a hollow tube and the cup leather forming the piston is secured
to it by screwing or securing a solid plug in the lower end, which plug carries a
screwed nut to hold the leather and metal washers in place. The pump is provided
with a flexible tube and valve attachment, and this latter may be held when not in
use in a suitable clip on the side of the pump, which clip may also have an air vent
through it which will correspond with the air vent of the pump. Or the clip may be
mounted on or form part of the crutch before described.

I, ARTHUR JAMES HENDERSON, late of 2 Lombard Court, but now of 15 and 16
Giltspur Street, both in the City of London, Consulting 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 relates to certain improvements in air pumps adapted for inflating
pneumatic tyres, and such as are suitable for carrying on cycles and the like or for
inflating footballs and similar small air filled articles.
In the accompanying drawing is illustrated one form of my invention-
Fig. 1 being a side elevation of a pump adapted for carrying on a cycle.
Fig. 2 a similar view but partly in section with some of the parts in a different
position and
Fig. 3 a view partly in section with the parts in the position shown in Figure 2 but
turned one quarter round.
The pump consists of the usual body portion a and piston rod band to the upper
end of this latter is attached a handle c which pivoted on the piston rod by means
of a pin d Fig. 3. The lower portion of the handle has a slot e in same which is
adapted to pass the piston rod when the handle is turned into the cross position shewn
in Figs. 2 and 3. The end of the handle is slightly expanded or flared as at f so that
it may be forced over the cap g closing the pump body a as shewn in Fig. 1 which
holds the two parts together and in line with each other. The upper portion of the
handle forms a receptacle h which is closed by a screw cap i and serves to hold small
articles such as pneumatic tyre repairing materials or other articles.
At the other end of the pump body is a base piece ; having an eye ¹ through
which are passed the ends of a bent wire forming a foot plate or piece k which is thus
pivotally held to the base so that it is capable of being turned down as in Fig. 2 or
folded up into the position shewn in Fig. 1 a small catch preferably formed of
spring steel secured to the side of the body a being arranged to hold it in the latter
position.
On the opposite side of the base j is a tube ³ communicating with the interior of
the pump and having a closed end, and an opening on the upper side to receive a
nozzle adapted to carry a flexible tube m the other end of which has the usual
screwed socket piece m¹ and securing nut m² for attaching the tube to the air valve
of a pneumatic tyre. This tube when not in use is held to the side of the body a by
a forked piece or clip n soldered or secured to the side of the pump body on which
the nut m² is held when the flexible tube m is in the position shewn in Fig. 1 by the
elasticity of the tube which is preferably of rubber. The air vent at upper end of
the pump body may be formed in this clip as shown at n¹ the opening communicating
with a corresponding opening in the pump body.
The piston 6 is preferably a hollow tube and has a plug o in the end thereof to
receive a screw p securing a washer q leather cup r and a discs (these parts forming
the piston) to the rod.
When not in use the pump may be carried on a cycle or the like in any of the
usual forms of clips at present in use and when it is desired to use it, the foot piece
or plate is turned down the foot placed upon it, the handle c is slightly raised to
free it from the cap g and is then turned to bring it in the position shewn in
Figs. 2 and 3 to form a handle to which both hands may be applied while the body
of the pump is held down by the foot,

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. The improved air pump adapted for inflating pneumatic tyres and the like
constructed substantially as described and illustrated.
2. An air pump adapted for inflating pneumatic tyres and the like provided with a
receptacle in the handle and a cover for same substantially as and for the purpose
described.
