COMPLETE SPECIFICATION.
An Improved Gland applicable to Piston and Pump Rods, Valve-
spindles, and the like.
I, WALDEMAR HARBINGER, of 104, Cleveland Street, South Shields, in the
County of Durham, 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 :-
This invention has for its object the construction of a gland which is principally
intended for use with marine and other steam engines, but is also applicable to other
engines and is designed with a view of catching and saving the waste steam water
and vapour that may escape round the piston and pump rods, valve spindles and
the like.
According to this invention, I form in the gland an annular chamber, communi-
cating with the condenser, hot well or feed water tank, and beyond this chamber
I provide a second stuffing box and gland.
In order that my invention may be fully understood, I will describe the same with
reference to the accompanying sheets of drawings, in which
Fig. 1 represents an elevation and Fig. 2 a section of the said gland.
The same letters of reference denote the same parts in both figures.
A is the main gland, which is provided with an annular chamber B. The
chamber B communicates with a two-way or other suitable cock by means of a
passage C. D is a screwed recess, which is provided for the attachment of the
two-way or other cock. The two-way cock is in the case of a marine or other
steam engine, connected to the condenser, hot well, or feed water tank, by means
of a pipe, and also with the atmosphere, thus serving as a test and delivery cock.
E is a screwed gland, which is provided with slots e. e. or other suitable means for
effecting its rotation in the usual way.
When the gland E has been correctly adjusted, it is fixed in the proper position
by means of a set-screw F, and screwed clamping piece G. H is a packing ring,
which is recessed to receive antifriction metal or other suitable packing material
and fits into a corresponding recess or seating provided in the main gland A. The
packing ring H is made in a suitable number of parts (preferably three, so as to fit
the piston or other rod or spindle, and thus prevent leakage of steam, water, or the
like. I is packing material, which is placed within the ring H.
When the invention is to be applied to piston rods and valve spindles, I prefer
to use asbestos and when it is to be applied to pumps, I prefer to use brown fibre,
but any other suitable packing may be employed. Jis a spiral wire coil or spring,
which is placed between the gland E and the packing ring H for the purpose of
keeping same tight against the rod.
In those cases in which the bottom of the main gland A consists of a bush K, as
shown in the accompanying drawings, I make the junction of the main gland and
bush steamtight, by means of a ring of packing of preferably the same material as
that used in the packing ring.
When used on marine engines, glands constructed as above effect a great saving
of fresh water, which is at present allowed to run into the bilge.

tion, and in what manner the same is to be performed, I declare that what I
claim is :-
The improved gland, substantially as described and shown, for the purpose
stated herein.
