Improvements in Means for Transmitting Fluids under Pressure.
I WILLIAM SMILEY HALSEY of Birdsboro in the County of Berks and State
of Pennsylvania, United States of America, Engineer, do hereby declare the
nature of this invention to be as follows:-
My invention relates to improvements in means for transmitting fluids under
pressure from a general supply reservoir, to be applied as a motive force or
otherwise.
The particular construction and arrangement of parts in connection with which
I have chosen to describe my invention is that adapted for use in connection with
a travelling crane, the reservoir extending along substantially parallel with the
path in which the crane is supposed to travel.

In carrying out my invention, I employ a reservoir for containing a fluid under
pressure, which may consist of a tube about which a receiver is fitted, and along
which the said receiver is adapted to slide. The reservoir tube is intercepted, at
suitable intervals, by sections for seating valves, to permit the passage of the
compressed fluid from the reservoir to the receiver. The reservoir may be
supported by yielding counterbalanced supports adapted to swing out of the
way as the receiver moves along the reservoir, and to automatically resume
their positions after the receiver has passed.
The sections form, at their exterior surface, a continuation of the outer casing
of the tubular reservoir, and are each provided with a valve seat surrounding an
opening leading from the interior of the section, through to the exterior thereof.
The exterior end of the opening is provided with a series of webs, to prevent an
extended interruption of the exterior surface of the reservoir, and a consequent
tendency to wear at the margin of the opening.
It is preferred that the distance between two consecutive valves along the
reservoir shall be about equal to the length of the interior of the receiver, so that
one valve will at all times be open to the interior of the receiver as it travels along
the reservoir, but the distance between the valves may be varied, so as to bring
more than one at all times within the receiver, or they may be placed so far apart
that there will be an interval between the closing of one valve, as the receiver
passes it, and the opening of a succeeding one, as the receiver reaches it.
Each valve and its stem is provided with an offset, with which a valve-operating
lever is adapted to engage, to open the valve.
The lever is supported at its ends, upon opposite sides of the valve stem, by
tappets, which extend through recesses in the wall of the reservoir to its exterior.
In practice, I provide these recesses with hollow screw plugs in which the tappets
slide, and locate packing around the tappet, between the plug and the bottom of
the recess. A shoulder or collar on the tappet serves to limit its reciprocating
movement by engagement with the plug, or packing adjacent thereto, and the
bottom of the recess or packing adjacent thereto, a space between the plug and
the bottom of the recess being left for the limited movement of the shoulder or
collar.
I also find it preferable to form the valve seat and the webs as part of a hollow
plug, which may be screwed into a hollow boss in the wall of the reservoir.
The receiver which carries the compressed fluid from the reservoir, to transmit it
to the point where it is to be employed as a motive force or other use, is provided

page_text: with packing at or near its ends, to close the joint Between the exterior wall of the
reservoir and the interior of the receiver against communication with the outside
air. A transmitting pipe is provided in the wall of the receiver. An inclined
faced operating nose is located at the end of the receiver in position to engage the
tappets to operate the valve, and an internally projecting rib extends from the
packing, at one end, to similar packing at the opposite end of the receiver, to hold
the tappets elevated while the receiver is passing the valve.
When the valve is in its closed position, and before the receiver has reached
either of the tappets, the later project beyond the wall of the receiver in the path
of the operating nose. As the latter engages the first tappet during the sliding
movement of the receiver along the reservoir, it will elevate one end of the valve-
operating lever, which, however, owing to a movement of the other tappet outwardly,
and to the curved bearing face of the offset on the stem, and the curved bearing on
the tappet, will not elevate the valve, but will place the lever, with its fulcrum
elevated, into such position, that when the nose reaches the companion tappet, it
will throw that end of the lever up, and with it the valve, to a full opening. The valve
will then remain open so long as the rib is in contact with the tappets, and will
fully close when its end has passed. the tappet first lifted, and permitted it to
resume its position projecting beyond the wall of the reservoir.
It will be observed that the valve is not opened in the slightest degree until the
packed end of the receiver has passed the valve, and thereby closed all escape
between the receiver and reservoir, and that the valve will fully close before
the opposite packed end of the receiver reaches it, so that no escape of the
compressed fluid can take place at the moment of closing.

Improvements in Means for Transmitting Fluids under Pressure.
I, WILLIAM SMILEY HALSEY of Birdsboro in the County of Berks and
State of Pennsylvania, United States of America, 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 following statement :-
My invention relates to improvements in means for transmitting fluids under
pressure from a general supply reservoir, to be applied as a motive force or
otherwise.
A practical embodiment of my invention is represented in the accompanying
drawings in which Fig. 1 is a view of a pipe reservoir, and receiver, in longitudinal
section, and Fig. 2 is a transverse section through line a, a of Fig. 1.
:
The particular construction and arrangement of parts which I have chosen to
illustrate my invention, is that adapted for use in connection with a travelling crane,
the reservoir extending along substantially parallel with the path in which the crane
is supposed to travel.
I have represented the distance between two consecutive valves along the reservoir,
as about equal to the length of the interior of the receiver, so that one valve will at
all times be open to the interior of the receiver, as it travels along the reservoir,
but the distance between the valves may be varied, so as to bring more than one at
all times within the receiver; or they may be placed so far apart, that there will
be an interval between the closing of one valve, as the receiver passes it, and the
opening of a succeeding one, as the receiver reaches it.
A represents a reservoir for containing a fluid under pressure, and consists, in
the present instance, of a tube about which the receiver B is fitted, and along
which the said receiver is adapted to slide. The tube A is intercepted at suitable

page_text: intervals by sections a for seating valves, to permit the passage of the compressed
fluid from the reservoir to the receiver, and is here represented as supported by
yielding counterbalanced supports A', adapted to swing out of the way, as the
receiver moves along the reservoir, and to automatically resume their positions after
the receiver has passed.
The sections a form, at their exterior surface, a continuation of the outer casing of
the tubular reservoir A, and are each provided with a valve seat a' surrounding an
opening a² leading from the interior of the section 2, through to the exterior thereof.
The exterior end of the opening a² is provided with a series of webs a³, to prevent an.
extended interruption of the exterior surface of the reservoir, and a consequent
tendency to wear at the margin of the opening.
The valve is denoted by C, and its steme is provided with an offset c', with which
the valve-operating lever D is adapted to engage, to open the valve.
The lever D is supported, at its ends, upon opposite sides of the valve stem c,
by tappets E, which extend through recesses a¹ in the wall of the reservoir, to its
exterior. In practice, I provide the recesses a¹ with hollow screw-plugs e, in which
the tappets slide, and locate packing e' around the tappet between the plug e and
the bottom of the recess a¹. A shoulder or collar on the tappet serves to limit
its reciprocating movement by engagement with the plug or packing adjacent
thereto, and the bottom of the recess a or packing adjacent thereto, a space between.
the plug e and the bottom of the recess at being left for the limited movement of
the shoulder or collar.
I also find it preferable to form the valve seat a' and the webs a³ as part of a
hollow plug F, which may be screwed into a hollow boss in the wall of the
reservoir.
The receiver B, which carries the compressed fluid from the reservoir, to
transmit it to the point where it is to be employed as motive force or other use, is
provided with packing b at or near its ends, to close the joint between the exterior
wall of the reservoir and the interior of the receiver, against communication with
the outside air. The transmitting pipe is denoted by B'. An inclined faced
operating nose 61 is located at the end of the receiver, in position to engage the
tappets to operate the valve, and an internally projecting rib 6 extends from the
packing b, at one end, to similar packing at the opposite end of the receiver, to hold
the tappets elevated while the receiver is passing the valve.
When the valve is in its closed position, and before the receiver has reached
either of the tappets, the latter project beyond the wall of the receiver, in the path
of the operating nose . As the latter engages the first tappet during the sliding
movement of the receiver along the reservoir, it will elevate one end of the
lever D, which, however, owing to a movement of the other tappet outwardly,
and to the curved bearing face of the offset on the stem and the curved
bearing on the tappet, will not elevate the valve C, but will place the lever D
with its fulcrum elevated into such position, that when the nose reaches the
companion tappet, it will throw that end of the lever D up, and with it the
valve C to a full opening. The valve will then remain open so long as the rib b²
is in contact with the tappets, and will fully close when its end has passed the
tappet first lifted, and permitted it to resume its position projecting beyond the wall
of the reservoir.
It will be observed that the valve is not opened in the slightest degree until the
packed end of the receiver has passed the valve, and thereby closed all escape
between the receiver and reservoir, and that the valve will fully close before the
opposite packed end of the receiver reaches it, so that no escape of the compressed
fluid can take place at the moment of closing.
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 combination, a reservoir for supplying a fluid under pressure, a receiver

page_text: surrounding the reservoir, & constructed to move along it, the said receiver having
fluid-tight joints with the reservoir which it surrounds, and means for transmitting
the fluid, under pressure, from the reservoir to the receiver at suitable intervals, and
intermediate of the fluid tight joints, substantially as set forth.
2. The combination with a reservoir & a receiver adapted to move along the
reservoir, of a valve for opening and closing communication between the reservoir
and receiver, a valve operating lever and lever operating tappets upon opposite
sides of the valve, and projecting into the path of the receiver, substantially as set
forth.
3. In combination, the reservoir, the receiver, the valve, the valve operating
lever having a loose connection with the valve, and tappets loosely connected
with the valve operating lever upon opposite sides of the valve, and under the
control of the receiver, the connections between the valve and lever and tappets
and lever being such, that one tappet may be operated without opening or closing
the valve, while the other tappet retains its previous adjustment, substantially as
set forth.
