page_text: I JOHN FRANCIS CHURCHILL M.D. of 6 Bentinck Street in the County of
Middlesex, do hereby declare the nature of this invention to be as follows:-
The object of this Invention is to dispense with the valve at present used in the
india rubber ball which serves as a blower for the ordinary spray producers.
In the present invention I employ a collapsible ball with the exit hole or pipe as
usual and a second or inlet hole which is covered by a pipe or equivalent preferably
of soft rubber which will compress more easily than the ball itself. This pipe or
equivalent reaches to or is situate at a convenient part of the ball so that it may
be readily compressed by the hand or fingers of the operator.
In action the ball is grasped by the hand one or more of the fingers resting upon
the soft rubber pipe, then upon squeezing the ball the soft pipe is compressed so
the air cannot escape that way, and has to pass out by the exit pipe; when the
pressure is released the soft pipe quickly resumes its proper form and the air enters
the ball by that means as the ball expands again to its proper forin.
The inlet hole may be formed in the portion of the ball opposite the outlet and
connected with a curved piece of metal or other rigid tubing to which the soft pipe
is fastened.

I JOHN FRANCIS CHURCHILL M.D. of 6 Bentinck Street in the County of
Middlesex, 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 object of this invention. is to dispense with the valve at present used in the
india rubber ball which serves as a blower for the ordinary spray producers.
In the present invention I employ a collapsible ball with the exit hole or pipe as
usual and a second or inlet hole which may be covered by a pipe or equivalent
preferably of soft rubber which will compress more easily than the ball itself.
This pipe or equivalent reaches to or is situate at a convenient part of the ball, so
that it may be readily compressed by the hand or fingers of the operator.
The inlet hole may be formed in the portion of the ball opposite the outlet and
connected with a curved piece of metal or other rigid tubing to which the soft pipe.
is fastened.
Referring to the accompanying drawing, which shows the apparatus in section,
A is the collapsible ball having the usual outlet hole or pipe B.
C is the soft rubber suction tube, preferably connected to a Ų shaped piece of
metal or other equivalent D.
In action the ball A is grasped by the hand, one or more of the fingers resting
upon the soft rubber pipe C, then upon squeezing the ball the soft pipe is com-
pressed so the air cannot escape that way and has to pass out by the exit pipe B:
when the pressure is released the soft pipe quickly resumes its proper form and the
air enters the ball by that means as the ball expands again to its proper form.
When used as an enema syringe water or the like would of course take the
place of the air.
Modifications in the structural details of this apparatus may be made, the
essential feature of closing the suction aperture of the collapsible ball by the hand
of the operator instead of by a valve being of course adhered to.
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. In an apparatus such as described the combination with the collapsible ball
of a suction pipe adapted to be compressed by the operator in the act of
compressing the ball substantially as and for the purpose specified.
2. In an apparatus such as described the method of closing the suction aperture
of the collapsible ball by the hand of the operator in the act of compressing the
ball whereby a suction valve may be dispensed with.
