PROVISIONAL SPECIFICATION.
Improvements in Air Pumps for Inflating Pneumatic Tires and like
purposes.
I, ALFRED ERNEST OAKES, of The Cedars, Ramsbury, Wiltshire, Engineer, do
hereby declare the nature of this invention to be as follows:-
This invention relates to the air pumps employed to inflate the tires of wheels
or pneumatic saddles or other similar articles, and consists in constructing the
barrel or cylinder of the pump with lugs or straps, so that it can be mounted on
a board or post or other fixture, moveable or otherwise.
The piston rod is forked or furnished with pivotted links, and is attached
pivotally to hand lever of suitable length which is fulcrumed to a pivot joint or
pin at its further extremity. This pivot joint may if preferred be sustained by
a bracket or brackets springing from the cylinder or the cap of the cylinder of
the pump.
In this way great power can be obtained and tires can be inflated with greater
ease and speed.
Improvements in Air Pumps for Inflating Pneumatic Tires and like
purposes.
I, ALFRED ERNEST OAKES, of The Cedars, Ramsbury, Wiltshire, 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 follow-
ing statement:—
This invention relates to the air pumps employed to inflate the tires of wheels,
pneumatic saddles, or the like, and is designed to effect this object much more
conveniently and rapidly than is possible with the pumps now in use.
In consists in constructing the barrel or cylinder of the pump with lugs or
straps, so that it can be mounted on a board or post or other fixture, movable or
otherwise.
->
The piston is also modified. It is forked or furnished with pivotted links, and
is attached pivotally to a hand lever of suitable length, which is fulcrummed to a
pivot joint or pin at its further extremity. This pivot joint or fulcrum is by

part thereof.
I will now describe the invention with reference to the accompanying draw-
ings in which:-
Fig. 1, shows a front elevation of the air pump attached to a back plate.
Fig. 2, shows a side elevation of Fig. 1.
Fig. 3, shows the pump attached to a movable post.
Referring to Figs. 1 and 2.-
a is the cylinder, secured to the backplate 6, by bolts or screws e passing through
cars or lugs d, d, attached solidly to, or formed on metal straps passing over the
cylinder a; e is the piston rod or plunger, the upper end of which is attached by
a pivot joint e¹ to a lug f on the lever handle g. The lever handle g is fulcrummed
at h¹ on the movable fulcrum h pivotted at i to a lug on the cylinder a. The
other end of the lever g is .terminated by a suitable handle; is the air outlet
pipe, the end of which is attached to the valve nozzle of the article to be inflated.
Referring to Fig. 3,-The cylinder is in this case attached to a post or upright k,
supported in any preferred manner upon a platform 7. The operator can place
a foot on the platform to keep the pump steady.
With reference to Figs. 1 and 2, it will be understood that the back plate b
may be attached to a wall, door, or the like, by any preferred means.
By the foregoing arrangement great power and ease is obtained.
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. In an air pump or inflator for tires and the like, the mode of attachment
by lugs or straps to a vertical post, door, or board fixed or loose, as herein described
and set forth.
2. In an air pump or inflator for tires and the like, the combination of the
lever handle g, bracket and lugs d, f, as herein described and set forth.
