A Rest for Securing a Tyre Inflator in Position during Inflation.
PERCY GEIKIE DONALD 9 Canonbury Lane Islington in the County of
Middlesex Clerk do hereby declare the nature of this invention to be as follows:-
This invention consists of a fixed or detachable apparatus to be used with a tyre
inflator, the object being to reduce the labour in inflating the tyre.
In order to shew accurately the way in which the apparatus is used I will make
use of illustrations.
Figures 1 & 2 shew the two different forms of the detachable apparatus, being
made of any suitable metal & fixed with nut and screw "C" to tighten it on any
sized inflator.
The band "B" will be flexible and will fix on inflator as shown in Fig. 3 except
when the apparatus (Fig. 2) is used, when it would be fixed not necessarily at the
end of the cylinder, but farther along when required.
The rest A which is the principle of the invention (whether fixed by band or
made as part of the inflator) fixes between the rim "E" and the tyre F as shown
in Fig. 4 in order to save the person using the inflator, from the exertion of
grasping tightly the cylinder of the inflator when inflating the tyre and thus saving
a great deal of labour.
Dated this First day of December 1896.

TUATION.
A Rest for Securing a Tyre Inflator in Position during Inflation.
I, PERCY GEIKIE DONALD, of 9 Canonbury Lane, Islington, in the County of
Middlesex, Clerk, 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 :-
The invention consists of a fixed or detachable apparatus to be used with a tyre
inflator, the object of which is to reduce the labour in inflating the tyre.
In order that my invention may be clearly understood and readily carried into
effect I will proceed aided by the accompanying drawings fully to describe the
same.
Figures 1 to 6 are perspective views of various forms of apparatus suitable for
attaching to existing inflators.
Figures 7 and 8 show other methods of carrying the invention into effect.
Fig. 9 is a view of an inflator with my invention applied thereto, and Fig. 10
shows the same inflator in position for use.
Fig. 11 is a view of one form of apparatus combined with a spring clip for
attaching the inflator to one of the tubes of the machine.
In all the figures like parts are indicated by similar letters of reference.

page_text: In carrying my invention into effect in its detachable form I take a band of
metal or other material a formed to fit around an inflator, having turned back ends
or lips a¹ both of which are formed with holes, one of said holes being screw
threaded to receive a screw b for tightening the band a upon the end of an inflator,
or I may use a nut, and bolt in which case the turned back end would merely be
formed with holes. To one side of the band I attach a short piece of metal or
other material e or I may form the parts a and c out of one piece of sheet metal
or other material. The part o may be made in various forms as shown in the
drawings.
When forming the rest as an integral portion of the inflator I may solder braze
or rivet the short piece of metal e to or cast it on the end of the inflator and I may
form a groove o¹ in the inflator cap adjacent to the part c as shown in Fig. 7.
In some cases I may form the groove c¹ nearer to the centre of the inflator as
shown in Fig. 8 and thus form the part c out of the inflator cap and dispense with
the additional short piece of metal herein before mentioned.
When it is desired to inflate the tyre, the part o is pressed in between the rim d
and the tyre e the end of the inflator resting against the rim when using the forms
shown in Figures 1, 3 and 4 but when using the forms of apparatus showu at
Figures 2, 5 and 6 part of the rest c.would come in contact with the rim.
It will be understood that by these means it is not necessary by one hand to
withstand the force exerted by the other hand in inflating the tyre as the rim of
the wheel will receive all the pressure. It will generally be found more convenient
to turn the wheel until the valve is at the top and to hold the inflator in a vertical
position.
The form of apparatus shown at Fig. 2 is intended for use with machines having
mud guards enabling the part e to be inserted between the rim and tyre and yet to
retain the inflator in a vertical position for use.
The form of apparatus shown at Fig. 5 is intended for use with inflators having
short connection tubes.
The form of apparatus shown at Fig. 6 is suitable for riders who prefer to hold
the inflator in a horizontal position for use.
In the combined form of apparatus shown at Fig. 11 the spring clipfis attached
to the band a.
It will be understood that although I have only described a band of metal for
attaching the part c to the inflator any other suitable form of attachment may be
employed.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A rest for a tyre inflator consisting of a short piece of suitable material of
convenient shape and means for removably attaching the same to the inflator
substantially as herein shown and described and for the purpose stated.
2. A rest for a tyre inflator consisting of a short piece of suitable material
permanently fixed to the same, substantially as herein shown and described.
3. A rest for a tyre inflator consisting of a short piece of metal attached to o
forming part of the side of the same in combination with a groove across the end
or cap substantially as herein described and shown in Fig. 7.
4. A rest for a tyre inflator consisting of a groove formed across the end or ca
of the same substantially as herein shown and described with reference to Fig. 8.
Dated this 26th day of February 1897.
