A, is a piece of tube about 21" in diar, and about 2" long or thereby, with one
end closed with the exception of a small hole about 3" or thereby for attaching the
small tube, B. B. is a small tapered tube about 2" long or thereby & about "in
Diar. with a small check valve at the screwed end marked, H. C. is a piece of
tube about 2" long and fitts into, A. & has a small recess about 16" deep or thereby,
by about " broad, at the inner or closed up end for the purpose of putting a little
packing to prevent escape when working, having a closed up end like, A. with a
small recess marked, D. about " in Diar. & about same depth for the purpose
of holding spring, E. E. is a small spiral spring about 3" long by " in Diar. or
thereby. F. is a piece of tube about long & 8 or thereby in diar. with a
valve marked, G. at the inside end & passes right up thro the spring, 1.E. through
the interior of same. I. is the outside end of, C. with a small hole marked, J. & is
about in Diar. for the admission of air. K. is a shield for covering the outside
of, C. & passing over the top or outside of, A. when compressed. The Inflator works
as well without as with said shield, being there only to prevent the hands coming in
contact with plunger, C. which is always more or less wett with oil. To work the
Inflator, B. is inserted into the tube of the football. The Inflator is then placed
between both hands & compressed by opening and closing both hands simul-
taniously, I.E. when it is compressed by the closing of the hands the moment the
pressure from the hands is relaxed the spring, E. forces, A. & C. from one another
again or back to there normal position. The two valves are placed visa-versa, so
every time the Inflator is compressed, the air in the inside compartment or chamber is
forced into the football, the air being drawn in at one end and forced out through
tube, B. the back pressure from the football being checked by valve, H. the air being
admitted by valve, G. The Inflator can be manufactured & sold about 1/- each or
thereby, are strong & substantial & understood almost without any explanation.

I, WILLIAM FRASER of 49 Oxford Road, Finsbury Park, London, N. 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:
This invention relates to a portable apparatus, for the inflation of foot and like game
balls, and consists essentially of a combined plunger and air chamber, working
telescopically within an open-ended cylinder, with coiled spring disposed between the
bottom of the latter, and a recess formed within the inner end of the former.
The combined plunger and air chamber, and cylinder, are provided with valves
respectively, the cylinder valvo being at the entrance of the pipe of an outlet nozzle.
The above arrangement, I also modify, by substituting for the combined plunger
and air chamber, a cup leather piston, which works to and fro within a cylinder,
whose enclosed end is provided with a nozzle, at the entrance pipe of which, is a
cono valve.
The return movement of the piston, is effected by a coiled spring, disposed
between the underside of a cap, on the end of a piston rod, and a bridge carried across
the open mouth of the cylinder.
Figure 1 represents in vertical seetion, a portable football inflater, constructed
according to this invention.
Figure 2 represents a transverse vertical section of the said inflater, upon the dotted
lines AB figure 1.
Figure 3 shows the inflater collapsed, whilst the said figure 1, shows it opened out.
Figure 4 is a plan of the enclosed end of the combined plunger and air chamber,
and figure 5 shows the said plunger, and air chamber, separately.
The same letters of reference indicate corresponding parts in figures 1 to 5.
a is a plunger and air chamber, working telescopically within a cylinder b, whose
outer end is closed by a cap 61, in the middle of which, is the pipe of a nozzle c,
wherethrough air is forced from the inflator.
The entrance to the pipe of the nozzle c, has an outwardly opening valve and valve
seat d,e; and disposed between the inside of the outer end 61, and the bottom of a
recess or well a², formed within the inner end of the combined plunger and air
chamber, is a coiled spring f, which when the inflater is collapsed, as in figure 3, it
rests within the said recess, which has at its bottom, a valve seat g, wherein a valve h,
opens outwardly, or in the direction as indicated by the arrow.
Air is admitted to the combined plunger, and air chamber, through a hole a³, in the
middle of the outer end a*.
The valves are prevented from rising too far from their seats by stops j, k.
In using the inflater, it is only necessary to force inwardly, the plunger and air
chamber a, when the valve g is closed, and the valve d opened, and the air contained
within the interior of the cylinder b, is forced passed the valve d, and up the nozzle c,
to the object to be inflated.

page_text: On relieving pressure from the combined plunger and air chamber, the same returns
to its normal position, by the opening out of the spring, which causes the instant
closing of the valve d, and opening of the valve h, thus admitting a fresh supply of
air to the interior of the cylinder b, ready for the next inward stroke of the plunger.
Figure 6 represents another form of my invention, and figure 7 is an inverted plan
of the same, and with the piston rod in section, on the dotted lines C D.
a is a cup leather piston, working within a cylinder b, whose outer end is enclosed,
and carries a nozzle c, whose inner entrance is provided with a coned seat e and
valve d.
The cup leather piston a, is enclosed between two discs or diaphragms a³, a³, whilst
the outward motion of the piston, is limited by a bridged stop 1, with guide and
bearing sleeve, wherethrough a piston rod a works; and to the inner end of the
said rod, the piston is connected, while the outer end carries a pusher cap a³.
Disposed between the underside of the pusher cap a³, and bridge 7, is a coiled
springf; so that on the inward stroke of the piston being made, by pressure applied
to the pusher cap, the air contained within the interior of the cylinder b, is forced
outwardly, through the nozzle c, by the valve d opening outwardly.
The return stroke of the piston, by the opening out of the spring, from its com-
pressed state or condition, causes the cup leather edges a¹, to turn inwardly, and
thus allow air to pass to the back of it, thereby dispensing with the use of an
inlet valve.
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.-
a,
First. A portable football inflater, consisting of a plunger and air chamber with
recess and valve, working telescopically within a cylinder b, whose outer enclosed end,
carries a nozzle c, provided with valve and valve seat, at its inner entrance; and
which said plunger and cylinder, has disposed between the inner end of the one, and
the bottom of the recess, or the inner end of the other, a coiled spring, for giving the
return stroke; the parts of which inflater, are constructed and arranged, and work,
substantially as described and set forth, in figures 1 to 5 both inclusive.
Secondly. The combination with an internally disposed coiled spring, of a well or
recess a², wherein the said coiled spring, is enclosed, when the apparatus is collapsed,
substantially as described and set forth in figures 1, 3 and 5.
Thirdly. A football inflater, consisting of a cup leather piston a, a', a³, a³, with
rod at, and pusher a³, working within a cylinder b, whose outer enclosed end, has a
nozzle, at the entrance of the pipe of which, is a valve, and cone valve and seat, while
the piston's return stroke is performed or made, by a coiled spring f, disposed between
a bridge and stop l, and the underside of the pusher cap, and which said parts are
constructed, arranged, and operate substantially as described and set forth in
figures 5 and 6.
