I ROBERT KIRK BOYLE of 15 St. Stephens Avenue Shepherds Bush in the County
of Middlesex Electrician do hereby declare the nature of this Invention to be as
follows:-
The object of my Invention is to provide arrangements whereby air pressure is
conveniently and economically supplied and applied in dwelling houses factories or
other places for operating bells signals machinery or the like.
According to my Invention I provide a storage of air under pressure and from
this I lead pipes to the several places where the air is to be utilized. The supply of
compressed air I prefer to store up by connecting with the reservoir or vessel in
which the air is stored some ordinary part or appliance outside or inside of or in
connection with or in proximity to the building or place where the reservoir is
situated which part or appliance is operated during the ordinary work or movements
of vehicles or persons inside or outside the building for instance there may be in
the floor of a passage or the like a part which is depressed as the weight.
of a person walking thereover comes upon it the depression of this part forcing air
into the reservoir by an inlet valve which valve closes when the said moving part
returns to its normal position under the action of a spring or the like so that the air
compressed into the reservoir is retained therein. The air passages leading from the
reservoir to the places where it is to be utilized are provided with valves operated by
press buttous or in any other suitable way by which the air is caused to pass to the
bell signal small machine or other device to be operated.

1, ROBERT KIRK BOYLE of 15 St. Stephens Avenue Shepherds Bush in the
County of Middlesex Electrician 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 my Invention is to provide arrangements whereby air pressure is
conveniently and economically supplied and applied in dwelling houses factories or
other places for operating bells signals machinery or the like.
According to my Invention I provide a storage of air under pressure and from
this I lead pipes to the several places where the air is to be utilized. The supply of
compressed air I prefer to store up by connecting with the reservoir or vessel in
which the air is stored some ordinary part or appliance outside or inside of or in
connection with or in proximity to the building or place where the reservoir is
situated which part or appliance is operated during the ordinary work or movements
of vehicles or persons inside or outside the building for instance there may be in the
floor of a passage or the like a part which is depressed as the weight of a person
walking thereover comes upon it the depression of this part forcing air into the
reservoir by a weighted inlet valve which valve closes when the said moving part

page_text: returns to its normal position under the action of a spring or the like so that the air
compressed into the reservoir is retained therein. The air passages leading from the
reservoir to the places where it is to be utilized are provided with valves operated by
press buttons or in any other suitable way by which the air is caused to pass to the
bell signal small machine or other device to be operated.
The accompanying drawing represents diagrammatically an arrangement according
to this Invention. A is a part of the flooring say in a passage in a house it being
capable of turning on the fulcrum a and being pressed upwards by a spring b bearing
on the plate a² attached to the part A. The part a prevents the part A from
projecting above the general floor level. The part A bears upon the moveable top or
piston (or a projection therefrom as at c) of a vessel in which air is compressed.
When tho part A is depressed the said air passes through the retaining valve d and
by the tube d to a reservoir 1) froin which it passes by the pipe to the bell or
other device which it is to work when a valve which may be situated for instance
at d' is opened by a push button or otherwise. When the pressure or weight on the
part A is removed the spring b returns it to its normal position and the hook a acts
on' the pin c to restore the top or piston to the position for a succeeding pressing
operation.
I have given the foregoing as an example of how my Invention may be performed
but I do not limit myself to the precise details shewn.
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 pneumatic appliance consisting of the combination of an air compresser and
receiver and connections to the device to be operated and a moveable part (such as A)
for compressing air for use in operating such device substantially as herein before
described.
2. The arrangement and combination of parts constituting the pneumatic apparatus
as herein before described and illustrated by the accompanying drawing.
Dated this 7th day of May 1890.
