I, SALOMON FRANK, of No. 4, Blucherplätz, Frankfort on the Main, in the
German Empire, Mechanical Engineer, do hereby declare the nature of this in-
vention to be as follows:-
This invention has for its object to provide a valve in which neither stuffing
box nor packing is employed.
In the said valve the valve-spindle is placed within a transversely corrugated
tube one end of the said tube being attached to the cover of the valve casing and
the other end of the said tube being connected with the valve proper in such a
manner that liquid cannot find its way into the interior of the tube.
The arrangement may be applied to screw down or self closing valves or any
other valve to which it is or may be applicable.
By inserting the valve in a pipe or main through which water or other liquid
passes under pressure, in such a position that the water or other liquid flows
through from the side of the valve opposite that at which the corrugated tube
is placed any objectionable back-pressure can be obviated by properly regulating
the spring-pressure to which the valve proper is subjected. The combined forces
of the spring and of the corrugated tube which is resilient in the transverse direc-
tion, can be so proportioned, that they cannot altogether overcome the water-
pressure acting upon the valve from below until, in consequence of the gradual
descent of the valve, the normal water pressure is restored.

Improvements in Valves.
I, SALOMON FRANK, of No. 4, Blucherplatz, Frankfort-on-the-Main, in the
German Empire, Mechanical Engineer, do hereby declare the nature of this in-
vention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This invention has for its object to provide a valve in which neither stuffing
box nor packing is employed.
In the said valve the valve-spindle is placed within a transversely corrugated
tube one end of the said tube being attached to the cover of the valve casing and

page_text: the other end of the said tube being connected with the valve proper in such a
manner that liquid cannot find its way into the interior of the tube.
The invention may be applied to screw-down or self-closing valves or to any
other valves to which it is, or may be, applicable. I will explain, with reference
to the accompanying drawings, the manner in which it can be practically carried
out.
Figure 1 is a longitudinal section of a screw-down valve constructed in accord-
ance with my invention.
b
Into the cap or cover v of the valve the end e of the transversely corrugated
tube c is cast, soldered, or otherwise secured, the other end, d, of the said tube c
being soldered, screwed or otherwise secured to the valve proper a.
The screw
on the spindle 6 engages in a corresponding screw-thread in the cover no stuffing
box or packing being required because the spindle is contained in a space or com-
partment which is tightly closed against access of water. As the said spindle
is turned the valve proper a is either lifted from its seat n or closed down upon
it, the corrugations of the tube c permitting the said valve proper to follow the
up-and-down movements of the spindle.
Figure 2 is a longitudinal section of a self-closing tap constructed in accord-
ance with my invention the parts which are like those shewn in Figure 1 being
marked with the same letters of reference with "1" added.
The valve-proper a¹ is raised by turning the lever k, i, h, by means of the loop g
provided on the rod b¹ and in thus rising it has to overcome the resistance of a
spring m which, when the lever is released, automatically forces the valve proper
back to the closed position, the action of the spring m being enhanced by the
resilience possessed by the corrugated tube c'. In other respects the construction
is the same as that shewn in Figure 1.
When the valve is placed in a pipe or main, through which water or other
liquid passes under pressure, in the direction of the arrows, any objectionable
back-pressure recoil or jar can be obviated by properly regulating the spring-
pressure to which the valve-proper a¹ is subjected. The combined forces of the
spring m and of the corrugated tube c', which is resilient in the transverse direc-
tion, can be so proportioned, that they cannot altogether overcome the water-
pressure acting upon the valve a¹ from below, until in consequence of the gradual
descent of the valve, the normal water pressure is restored.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim is:-
In a valve a transversely-corrugated tulie connected at one end with the valve-
casing or cover and at the other with the valve proper and so as to enclose the
valve spindle in such a manner that the space in the interior of the tube is
tightly closed against the water-chamber of the valve, substantially as herein-
before described.
