IMPROVEMENTS CON- NECTED WITH PNEUMATIC PUMPS FOR TRANSFERRING PAPER, MONEY AND OTHER ARTICLES FROM ONE PLACE TO ANOTHER
Year: 1885

page_text: I, CHARLES FREDERICK COOKE of the firm of Mess T. Cooke and Sons,
Opticians and Engineers of Buckingham Works, Bishophill, York, in the County
of York do hereby declare the nature of my invention for "IMPROVEMENTS CON-
NECTED WITH PNEUMATIC PUMPS FOR TRANSFERRING PAPER, MONEY AND OTHER
ARTICLES FROM ONE PLACE TO ANOTHER" to be as follows:-
My Invention has reference to apparatus to be employed for quickly trans-
ferring paper, money, and other articles from one place to another through a tube,
such apparatus being specially adapted for use in telegraph offices for forwarding
telegraphic messages from one room to another and for use in Offices, Ware-
houses, and shops where coins and other articles can be sent from one part of the
room to another.
For the purpose of carrying out my invention I arrange that the apparatus shall
be able either to blow the articles through the tube by a blast of air, or draw them
through by suction, and for this purpose I employ any ordinary form of air
pump, or special form consisting of two cylinders, and connect therewith two, four,
or other suitable number of moveable valves, and a corresponding number of
stationary port holes.
A dome or other shaped cover is placed in connection with the ports and valves,
and the pipe for conveying the paper or other material is connected to the dome at
its centre. Therefore when an article is required to be blown through the tube
the valves which are made moveable, but work in connection with stationary port
holes are moved by a handle or other suitable means to a position opposite the
blow valves, and on operating the pump which can be effected either by manual or
other motive power, the articles placed in the tube will be blown through to the
other end of the said pipe, and transferred thereby to some other part of the
building, but when any article is required to be brought back through the tube,
the suction valves are moved opposite the other port holes, and on the pump
being actuated the current of air is reversed, and the article made to return,

Improvements Connected with Pneumatic Pumps for Trans-
ferring Paper, Money, and other Articles from One Place to
Another.
I, CHARLES FREDERICK COOKE of the firm of Messrs T. Cooke and Sons
Opticians and Engineers of Buckingham Works, York, in the County of York do
hereby declare the nature of my invention for "IMPROVEMENTS CONNECTED WITH
PNEUMATIC PUMPS FOR TRANSFERRING PAPER, MONEY, AND OTHER ARTICLES FROM
ONE PLACE TO ANOTHER," and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement :-
My invention has reference to apparatus to be employed for quickly trans-
ferring paper, money, and other articles from one place to another through a tube,
such apparatus being specially adapted for use in telegraph offices for forwarding
telegraphic messages from one room to another, and for use in offices warehouses
and shops where coins and other articles can be sent from one part of the room to
another.
For the purpose of carrying out my invention I arrange that the apparatus shall
be able to either blow the articles through the tube by a blast of air or draw them
through by suction, and for this purpose I employ any ordinary form of air pump
or special form consisting of two cylinders and connect therewith two, four, or
other suitable number of moveable valves, and a corresponding number of stationary
port holes.
A dome or other shaped cover is placed in connection with the ports
and valves and the pipe for conveying the paper, or other material is connected to
the dome at its centre Therefore when an article is required to be blown through
the tube the valves which are made moveable, but work in connection with
stationary port holes are moved by a handle or other suitable means to a position
opposite the blow ports, and on working the pump which can be effected either by
manual or other motive power the articles placed in the tube will be blown
through to the other end of the said pipe, and transferred thereby to some other
part of the building, but when any article is required to be brought back through
the tube, the suction valves are moved opposite the same port holes, and on the
pump being again worked the current of air is reversed and the article is made to
return.
In order that my invention may be better understood I herein make reference to
the accompanying sheet of drawings wherein Fig. 1 is elevation of apparatus con-
structed according to my invention, and Fig. 2 front view with the dome removed
so as to more clearly shew the parts. A represents a double acting pneumatic
cylinder having a piston B, piston rod O, connected to a hand lever D, hinged at E,
to bracket F. On one side of the cylinder are placed four valves G, G, H and H¹
the two former being constructed as blow valves, and the two latter as exhaust? or
suction valves.
These valves which are covered with leather cover openings made in the face
of the cylinder and communicating with the top and bottom of the cylinders by
suitable openings or passages.

page_text: These valves are not fixtures, but are supported by studs a carried by small
brackets I made fast by screws or other means to the plate J which can be
oscillated backward and forward by handle L for purposes hereinafter explained.
P is a dome made with four port holes M, M¹ and N, N, the former being
employed for blowing purposes and the latter for exhaust or suction purposes.
This dome with the port holes is fixed by bolts or other means to the face of the
cylinder and the ports are arranged to be in communication with the several
moveable valves.
The position of the valves as shown in Fig. 2 indicates that they are in position
for the blow which is for sending a message, but by lowering the handle L until it
reaches the stop piece b the action of the valves will be reversed as the suction
valves will have been brought opposite the same ports, the air for blowing enters
in under the cover of the dome at point c, but the air for suction is drawn from
the dispatch tube.
The modus operandi is as follows;
When it is necessary to draw a message or coin down the dispatch tube R, the
valves H and H₁ are moved opposite the stationary ports N and N, and the
lever D operated so as to cause the piston to descend to the bottom of the cylinder,
this action draws the air from the dispatch tube and the message or coin with it,
such air escaping out of the blow off ports, but when a paper or coins have to be
sent through the dispatch tube P, they are placed into a suitable receiver or pocket
fitting the inside of the tube; the blow valves G and G¹ are then placed opposite
the blow ports M and M², the lever D being then operated as before and the
message is blown to the other end of the dispatch tube, the necessary air for that
purpose being supplied from outside which enters in under the cover of the dome
at point c.
By the employment of apparatus constructed as herein set forth, messages, coins,
or other suitable articles can be sent up or drawn through the tube in a very easy
manner, whilst the means employed to change the valves so as to perform exactly
opposite work is also very easily effected.
Having now described my invention and shewn how the same is to be carried
into practice I would have it understood that I do not limit or confine myself to
the details herein set forth, as they may be varied without departing from my
invention, what therefore I claim is;
In connection with a pneumatic pump the combination of moveable valves with
fixed and stationary port holes in manner and for purposes substantially as shewn
and described.
