Improved Accessories for Use in Conjunction with Air Pumps.
1, HAROLD RICHARD GOODWIN, of Rosedale, Elnis Lane, Sudbury, near Harrow,
in the County of Middlesex, Accountant, do hereby declare the nature of this
invention to be as follows:-
This invention has reference to improved accessories specially suitable for use
in conjunction with air pumps for inflating pneumatic tyres whereby such pumps,
even when made short and of larger bore than usual, can be operated in a more
advantageous manner and with less fatigue than has heretofore been usual, this
result being attained by obviating the necessity of holding the stationary part of
the pump by one hand whilst the other part of the pump is being operated by the
other hand.
An accessory for this purpose according to one arrangment comprises a support
adapted at its lower end to rest and he held upon the ground and at its upper end
to receive and hold the delivery end of the stationary part of the pump and permit
of the passage of the flexible pipe that connects such pump part to the air valve of
the pneumatic tyre the arrangement being such that when in use, the device acts
to hold the one part of the pump stationary whilst the other part is being operated.
In one construction of this kind the support comprises a metal bar of T or shape
at its lower end so that it can be readily held upon the ground by the foot of the
operator, its upper end being provided with a horizontal extension formed with a
slot open at one end and having a spring or other clip device, the arrangement
being such that the stationary part of the pump with flexible delivery pipe can be
readily engaged with the slotted part of the support by a lateral movement of the
one part towards the other. The slotted part of the support may advantageously
be provided with material such as leather or india rubber to prevent damage by
abrasion, and also the production of a disagreeable noise of the pump.
The clip
device may be of various kinds, conveniently it may be a strip of spring steel
screwed or otherwise fixed in or on the slotted part of the extension so as to form
two spring arms that will clip around the hollow piston rod or other fixed part of
the pump and hold the same in position during the suction stroke of the pump.
This above construction of supporting device is suitable for single acting pumps
the piston rod of which is provided at its outer end with a cross bar or lateral
extensions adapted to rest upon the slotted extension.
In another construction adapted for use with double acting pumps the support
is provided at its upper end with two slotted parts arranged a short distance apart
and one below the other so as to receive between them the cross bar or lateral ex-
tensions on the pump piston rod and hold the same during each stroke of the
pump. Or the support may be constructed as described for a single acting pump,
and the piston rod of the pump he provided with two collars or pairs of lateral
extensions adapted to receive between them the slotted horizontal extension on the
support.
The foot and upper horizontal extension or extensions may be hinged or other

page_text: wise connected to the bar carrying them as to permit of the device being folder
or made into a small package for convenience of being carried. The foot and
other parts may be provided with one or more polygonal holes or with one or more
slots or recesses the sides of which are stepped or toothed to adapt the device for
use as a spanner, for nuts of different sizes. One or each of the free ends of the
device may also be adapted for use as a screw driver.
According to another arrangement in lieu of a 'support for holding the fixed par
of the pump, I provide such part with a pair of lateral extensions and with a pair
of eyes or equivalently formed holding parts, one of the lateral extensions being
curved or shaped to rest upon one or other of the stay rods connected to the bearing
of the rear wheel of a bicycle and the other lateral extension being curved or
shaped to rest against the sides of the fork in which the front wheel of the bicycle
is mounted, so as in each case to take the strain during the compression strokes
of the pump, one or other of the eyes or equivalent parts serving as a conven cut
means for holding the fixed part of the pump in position during the suction strokes.

Improved Accessories for Use in Conjunction with Air Pumps.
I, HAROLD RICHARD GOODWIN, of Rosedale, Elms Lane, Sudbury, near Harrow,
in the County of Middlesex, Accountant, 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 has reference to improved accessories specially suitable for use in
conjunction with the ordinary air pumps commonly used for inflating pneumatic
tyres whereby such pumps, even when made short and of larger bore than usual,
can be operated in a more advantageous manner and with less fatigue than has
heretofore been usual, this result being attained by obviating the necessity of
holding the stationary part of the pump by one hand whilst the other part of the
pump is being operated by the other hand.
An accessory for this purpose according to this invention comprises a support
adapted at its lower end to rest and be held upon the ground and at its upper end
to receive and hold the delivery end of the stationary part of the pump and permit
of the passage of the flexible pipe that connects such pump part to the air valve
of the pneumatic tyre, the arrangement being such that when in use, the device
acts to hold the one part of the pump stationary and above the ground whilst the
other part is being operated.
In one construction of this kind the pump accessory comprises a metal bar or
support of T or L shape at its lower end so that it can be readily held upon the
ground by the foot of the operator, its upper end being provided with
a horizontal extension formed with a slot open at one end and with
a spring or other clip device, the arrangement being such that the stationary
part of the pump with the flexible delivery nipe can be readily engaged with the
slotted part of the support by a lateral movement of the one part towards the other.
This construction is suitable for a single acting pump.
In another construction, adapted for use with double acting pumps, the support
is provided at its upper end with two slotted parts arranged a short distance apart

page_text: and one below the other so as to receive between them the cross bar or lateral
extensions commonly provided on the piston rod of some air pumps and hold the
same during each stroke of the pump.
The foot portion of the support may be hinged or otherwise so connected to the
har carrying it as to permit of the support being folded or made into a small
package for convenience of being carried.
As will be obvious pump accessories of the kind referred to can be constructed
in different forms and of various materials, such for examples as gun metal,
malleable iron, aluminium, steel, celluloid, vulcanite and wood.
Fig. 1 of the accompanying drawings is a perspective view showing one construc-
tion of pump rest or support according to this invention suitable for a single
acting air pump; and Fig. 2 is a side elevation showing how the said accessory is
used for supporting the pump whilst inflating a pneumatic tyre.
In this example the pump rest or support (hereinafter called the pump support)
comprises a flat metal har 1 having a tee shaped lower end formed by extensions 2
and 2 that serve to provide an efficient base for the support. The lower exten-
sion 2 also forms a foot piece whereby the pump support can be readily held upon
the ground by the foot 3 of the pump operator (Fig. 2). The upper end of the
support is made with a horizontal extension 4 formed with a slot 5 open at one end
so that the stationary part 6 of an air pump 6-7 with flexible delivery pipe 8
can be readily engaged with the slotted part of the support by a lateral movement
of the one part towards the other. The slotted upper extension 4 may be provided
with a spring or clip device which can be of various kinds. In Fig. 1 it is shown
as a bent strip 9 of spring steel fixed by a screw or equivalent device in the slotted
part of the extension 4 so as to form two spring arms that will clip around the
annularly grooved end 6 of the hollow piston rod 6 which, in this example con-
stitutes the fixed part of the pump, and hold the same in position during the
suction stroke of the pump, that is to say, whilst the movable portion of the pump,
in this case the pump barrel 7, is being raised. The support just described is
suitable for a single acting pump the piston rod of which is provided at its outer
end with a cross bar or lateral extension 6b adapted to rest upon the slotted exten-
sion of the support which takes the thrust during the downward forcing or
delivery strokes of the pump.
Figs. 3 and 3 are elevations at right angles to each other and Fig. 3" a plan,
showing a modified construction of the support adapted to hold down the barrel
portion of an ordinary telescopic single acting pump whilst the piston thereof is
making its upward or suction stroke. In this case the clip device is arranged on
the slotted extension 4 and consists of a strip 9 of steel bent to a partly circular
shape and of a size adapted to grip the lower end of the pump barrel, the ends of
the strip being bent outward as shown so as to facilitate the insertion between
them of the pump barrel by a lateral movement of the one part towards the other.
The opened ended slot 5 in the extension 4 permits of the passage of the flexible
air delivery tube 8 which is attached to the axial air delivery outlet of the pump
barrel. so that such tube can extend centrally and axially through the extension 4
and thence pass to the air valve 10 of the pneumatic tyre 11 to be inflated. The
clip device 9 can be secured by a rivet to a lug 1* on the slotted extension 4 upon
which the pump barrel rests, as indicated in dotted lines in Fig. 3, and which
takes the thrust on the downstroke of the piston. In order to make the support
light, its upright portion is shown as consisting of two uprights 1 connected to
gether at the top and bottom by the slotted horizontal extensions 4 and
respectively. The foot piece 2 is made of wire bent to a loop shape, or it may be
of other shape, and is hinged or jointed to the uprights at 2b, so that when not
in use, it can be folded up into the position indicated in dotted lines to enable
the support to be conveniently carried.
Figs. 4, 4 and 5 show a construction of my pump support suitable for use with
double acting air pumps. In the arrangement the bar 1 is provided with two
slotted laterally arranged parts 4, 4 arranged a short distance apart and one below

page_text: the other so as to be capable of receiving-between them the cross bar or lateral
extensions on the piston rod of an ordinary double acting pump and of holding
the same in a vertical direction during each stroke of the pump. The foot piece 2
is here shown made as a separate piece provided with a tongue or projection 2
adapted to be slipped into a corresponding hole 24 in the enlarged lower part 2"
of the bar 1 so that the two parts can be readily connected together for use as shown
in Fig. 5, and can subsequently lie detached from each other as shewn in Figs. 4
and 4 to facilitate their being packed in a small receptacle. The slot 5 in each
extension is preferably extended througli, the top of the har 1 as shown so as to
enable the axis of the pump to be brought as near'as possible over the bar 1. The
upper end of the bar I shown in Figs 1 and 2 may be similarly slotted for a like
reason.
Fig. 4" shows a pump support somewhat like that represented in Figs. 4, 4 and 5,
hut in which the foot piece 2 is hinged at 2 to the lar 1 so as to admit of its being
folded up against the said bar when not required for use.
Figs. 6 and 6 are elevations at right angles to each other and Fig. a plan
showing a modified construction in which the upper slotted part 4 of the support
is formed by a clip device 9 similar to that shown in Figs. 3 to 3 except that
the end portions of the bent steel strip constituting such clip device are cut away
at their undersides so as to leave between them and the lower slotted part 4,
spaces 4 capable of receiving and holding the cross bar or lateral extensions on the
piston rod of a double acting pamp, as in the example shown in Fig. 5, whilst the
clip device 9 is also available for holding the barrel portion of a telescopic pump
baving a reciprocating piston, like the clip device 9 shown in Figs. 3, 33". The
support shown in Figs. 6, 6, 6 is therefore adapted for use with either of the
two forms of air pump now most commonly in use. The body of the support and
foot piece are constructed and arranged like those of the support shown in
Figs. 3, 3, 3. The clip device 9b may be made separate from the support and
be secured to a lug 4* thereon, as shown in Figs. 6, 6, 6, but it may be formed in
one with the support, as by casting, and as shown in Figs. 7, 7 and 7" which are
similar views to Figs. 6 6 6 respectively. In this case the clip device will
usually be of thicker material and of less elasticity than the steel strip shown in
Figs. 6 G and G. For this reason the pump barrel may be engaged with or
disengaged from the clip device by an axial movement of the one part relatively
to the other instead of by a lateral movement.
A support of the kind shown in Figs. 1 and 2 may also he used with double
acting pumps if the piston rod 6 of the pump be provided with two collars or pairs
of lateral extensions 6 adapted to receive between them the slotted horizontal
extension 4 of the bar 1, as shown in Fig. 8, so that such extension will hold the
pump rod in each direction during the reciprocating movements of the pump
barrel. The collar or extensions 6 may, if desired, be formed on the inetal
fitting 8 that is ordinarily used for connecting the flexible delivery pipe 8 to the
hollow piston rod as shown in Fig. 8.
Figs. 9 and 9 are elevations at right angles to each other showing a pump
support comprising a pair of upright bars 1 carried by the enlarged perforated lower
part 2 in which a removable foot piece 2 is inserted, their upper ends being con-
nected together by a cross piece 1" and provided with horizontal extensions 4
arranged at a distance apart horizontally so as to form a slot for the reception of the
grooved portion of the pipe fitting S, (or piston rod end, Figs. 1 and 2).
Figs. 10 and 11,aro elevations at right angles to each other and Fig. 11' a plan,
showing a pump support made of a piece of tubing 1 which has a portion cut away
at 1 and is slotted at 5, the free ends thus formed being straightened and shortened
so as to form a slotted upper part or extension 4 that can be engaged with the outer
grooved end of a pump rod or pump fitting, the lower end of the tube being formed
with oppositely arranged holes 2 for the reception of a removable foot piece 2.
Figs. 12 and 13 are elevations at right angles to each other, and Fig. 14 a plan,
showing a further modified" construction in which the bar'1 is grooved to render

page_text: it lighter and to form a slotted upper end 4 adapted to receive and hold the grooved
end of the pipe fitting S, (or of the piston rod). The removable foot piece 2 may
also be slotted as shown at 2, to make it lighter.
Figs. 15, 16 and 17 are respectively side, front and plan views showing a further
modified construction of pump support. It comprises two uprights 1 connected
together by an upper cross piece 1" and a base piece 2 each of the uprights being
formed at the upper end with a slot 5 to permit of the ready engagement therewith
of one of two lateral and oppositely arranged pins or projections on the fixed part
of the pump, or a fitting attached thereto. The foot piece 2 is of loop form pivoted
to.the base piece 2 at 25 so that it can be folded inth the inoperative position shown
in dotted lines and turned downward into the position shown in full lines for use
at which time its pivoted ends hear against the front sides of the upright bars 1
as shown. When not in use the pump barrel 7 may, as shown in dotted lines in
Fig. 15, be held between the cross bar 1 and the end 2 of the foot piece 2 both of
which are made concave to fit the pump barrel.
Although I have for the sake of clearness, shown the pump support in Figs 2
and 6 with its slotted upper end and foot piece parallel with the wheel the tyre of
which is to be inflated, it will usually be more convenient to place it in a position.
at right angles to that shown.
In order that the support may be made short and he placed sufficiently
far from the wheel to enable the pump carried thereby to be con-
veniently worked without liability of the user's hand coming in contact with any
part of the bicycle or other machine, it will usually be desirable when using any
one of the pump supports hereinhofore described to use an air delivery tube 8 of
about two or three times the usual length. Instead however of constructing the
support as shown in Figs. 1 to 17 inclusive so as to hold a pump with its axis
vertical, it may obviously be so constructed as to support the pump with its axis
inclined to the ground. With such an arrangement, the air delivery tube 8 may
be of the usual length. Fig. 18 is a side elevation and Fig. 19 a sectional plan
showing one arrangement for this purpose in which the pump support, the upper
part of which is similar to that of the support shown in Figs. 7, 7, 7", has the
lower ends of its uprights I rounded and hinged or jointed by pins at 2b to the
inner sides of the ends of the foot piece 2 so that it can be turned from the vertical
to any desired inclined position as shown.
Figs. 20 and 21 are front and side elevations showing a modified arrangement
in which the lower part of the hody 1 of the support is connected to the foot piece 2
by a ball and socket joint so that the support and pump held thereby can he
turned in any direction about the joint to suit requirement.
As will be seen, by my invention an ordinary air pump having an axial or central
air delivery outlet can be connected by means of its flexible tube with the air
valve of a tyre in the usual way, that is to say by rotating it about its longitudinal
axis, and can then be supported at its lower end by one of my supports which can
be applied thereto in a lateral direction without interfering with the flexible air
tube.
Ilaving now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what I
claim is:-
1. An air pump accessory consisting of a support adapted at its lower end to
rest and be held upon the ground and at its upper end to receive and hold the
delivery end of the stationary part of an ordinary air pump and permit of the
passage of the flexible and axial or central air delivery pipe used to connect such
pump part to the air valve of a pneumatic tyre, the arrangement being such that
when in use, the support acts to hold the one part of the pump with flexible air
tube stationary and above the ground whilst the other part is being operated, and
that such support can be readily detached from the pump when desired, substan-
tially as herein described.

page_text: 2. A pump accessory consisting of a rest or support adapted at its upper end to
be sprung by means of a clip device on to the normally fixed part of an air pump
so as to support such part of the pump and the flexible air tube extending therefrom
above the ground and at its lower end to be held upon the ground by the foot of
the user, substantially as described.
3. A pump support of the kind referred to in Claim 1 provided at its lower end
with a laterally extending foot piece or base by which it can rest and be held upon
the ground and having at its upper end a slotted, recessed or equivalently formed
part or parts adapted to admit of the support being engaged by a lateral move-
ment with the delivery end of the stationary part of a pump provided with a central
flexible air tube, and support such part of the pump with tube above the ground,
substantially as herein described.
4. A pump accessory of the kind specified in the preceding claims in which the
foot piece or base is hinged or otherwise connected to the support in such a manner
as to be movable relatively thereto, substantially as described.
5. My improved pump accessories or supports constructed and arranged substan-
