Improvements in Mechanism or Apparatus to be used on Locomotives,
in connection with Steam Sanding and Warming, or
Injectors for Steam Sanding and for Warming Railway Vehicles.
We, JAMES GRESHAM, Director of the Firm of Gresham and Craven Limited,
of Craven Iron Works, Salford, in the County of Lancaster, Engineer, and
HARRY EDWARD GRESHAM, of the same place, Engineer, do hereby declare the
nature of the said invention, to be as follows:-
Our invention refers to a combination or to combinations of apparatus alone,
or with a combined injector, or a combined injector and steam and feed valves
(these steam and feed valves or either or both being hereinafter referred to and
included in the term "combined injector ") for supplying steam for warming the
vehicles of a railway train, and also for what is known as steam sanding." that
is, applying sand to the driving wheels of locomotives, or for either purpose when
combined with a combined injector.
"
The main object of our improvements is to combine the apparatus for the above
named purposes so as to make as few connections with the boiler of the locomotive
to which they are applied as possible, or in other words, to so combine the
apparatus that one connection with the boiler will do for two or more of the
above named purposes.
According to one arrangement of our invention we modify, combine and
arrange a combined injector so that a passage for steam is formed in the casing
which will lead to a valve, a cone valve by preference, on the end of a spinde
which is screwed near the valve and screws through a socket screwing fluid
tight into the casing of the combined injector, this socket also forming a packing
gland for the spindle of the valve which is actuated by a handle on the exterior
end of the spindle. The outlet from the valve for warming is by a passage in
the casing of the combined injector leading to a branch formed therein, to which
the pipe
coupled up that conveys the steam to the warming arrangements in
the vehicles of the train coupled up to the locomotive steam boiler having the
combined injector and warming valves applied to it.
Our invention also consists in combining with the combined injector having
the valve apparatus for supplying steam for warming above described, a cone
cock or valve by preference for steam sanding.
There is a cone cavity formed within the casing of the combined injector and
warming valve, in which casing there is also a passage to the cone cock from the
passage for steam from the boiler formed in the casing of the combined injector.
In this casing there is a port in the side of the cone plug that admits steam into
the axis of the plug and then out of it from a port in the plug to a passage in
the casing but before the steam can get into this passage it has to force open a
valve kept pressed against its seating by a spring. when there is no pressure of
steam and after passing the valve, the steam goes along a passage to an outlet
branch to which the pipe is connected that leads to the sanding ejectors. There

page_text: are arrangements, the above named lifting valve is one, to prevent condensed
steam from passing to the pipes leading to the sanding ejectors, and there is a
groove round the cone plug and passages which are connected with a passage in
the casing leading to a branch with which a pipe is connected for conveying
away the drip or condensed steam or leakage from the cone cock.
According to our invention we also combine in one casing the valve for steam
for warming, and the cone valve and its connected arrangements above described
for steam sanding. We prefer to arrange the axis of the screw spindle of the
valve for warming in the same plane as that of the axis of the cone cock.
The screw spindle having the cone valve on its end screws into a socket screw-
ing fluid tight into the casing, in which socket there is a gland stuffing box for
the spindle, there is or may be a branch for a pipe leading to a pressure gauge
to show the pressure of steam in the pipes going to the warming apparatus.
The handle on the spindle of the cone cock, which is also in a socket screwed
into the casing fluid tight, and in this, the stuffing box for the spindle is formed,
the spindle having a handle on its outer end, which handle has a projection to
act as a stop and pointer.

Improvements in Mechanism or Apparatus to be used on Locomotives,
or with
in connection with Steam Sanding and Warming,
Injectors for Steam Sanding and for Warming Railway Vehicles.
We, JAMES GRESHAM, Director of the Firm of Gresham and Craven Limited,
of Craven Iron Works, Salford, in the County of Lancaster, Engineer, and
HARRY EDWARD GRESHAM, of the same place, 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:—
Our invention refers to a combination or to combinations of apparatus alone,
or with a combined injector, or a combined injector and steam and feed valves
(these steam and feed valves or either or both being hereinafter referred to and
included in the term combined injector") for supplying steam for warming the
steam sanding," that
vehicles of a railway train, and also for what is known as
is, applying sand to the driving wheels of locomotives, or for either purpose when
combined with a combined injector.
The main object of our improvements is to combine the apparatus for the above
named purposes so as to make as few connections with the boiler of the locomotive
to which they are applied as possible, or in other words, to so combine the
apparatus that one connection with the boiler will do for two or more of the
above named purposes.
According to one arrangement of our invention we modify, combine and
arrange a combined injector so that a passage for steam is formed in the casing
which will lead to a valve, a cone valve by preference, on the end of a spindle
which is screwed near the valve and screws through a socket screwing fluid
tight into the casing of the combined injector, this socket also forming a packing
gland for the spindle of the valve which is actuated by a handle on the exterior
end of the spindle. The outlet from the valve for warming is by a passage in

page_text: the casing of the combined injector leading to a branch formed therein, to which
the pipe is coupled up that conveys the steam to the warming arrangements in
the vehicles of the train coupled up to the locomotive steam boiler having the
combined injector and warming valves applied to it.
Our invention also consists in combining with the combined injector having
the valve apparatus for supplying steam for warming above described, a cone
cock or valve by preference for steam sanding.
There is a coue cavity formed within the casing of the combined injector and
warming valve, in which casing there is also a passage to the cone cock from the
passage for steam from the boiler formed in the casing of the combined injector.
In this casing there is a port in the side of the cone plug that admits steam into
the axis of the plug and then out of it from a port in the plug to a passage in
the casing but before the steam can get into this passage it has to force open a
valve kept pressed against its seating by a spring, when there is no pressure of
steam and after passing the valve the steam goes along a passage to an outlet
branch to which the pipe is connected that leads to the sanding ejectors. There
are arrangements, the above named lifting valve is one, to prevent condensed
steam from passing to the pipes leading to the sanding ejectors, and there is a
groove round the cone plug and passages which are connected with a passage in
the casing leading to a branch with which a pipe is connected for conveying
away the drip or condensed steam or leakage from the cone cock.
According to our invention we also combine in one casing the valve for steam
for warming, and the cone valve and its connected arrangements above described
for steam sanding. We prefer to arrange the axis of the screw spindle of the
valve for warming in the same plane as that of the axis of the cone cock.
The screw spindle having the cone valve on its end screws into a socket screw-
ing fluid tight into the casing, in which socket there is a gland stuffing box for
the spindle, there is or may be a branch for a pipe leading to a pressure gauge
to show the pressure of steam in the pipes going to the warming apparatus.
The spindle of the cone cock, is also in a socket screwed into the casing fluid
tight, and in this, the stuffing box for the spindle is formed, the spindle having a
handle on its outer end, which handle has a projection to act as a stop and pointer.

Figs. 2, 3 and 4 illustrate. our improved combination of valve and cock
apparatus for supplying steam for sanding and warming, combined with the com-
bination injector apparatus. This apparatus may be formed in the same casing
with the combination injector or may be formed for convenience in construction
in a separate casing united by a flange with the casing of the combination injector.
In Figs. 2, 3 and 4 the apparatus is supposed to be in a separate casing united
with the combination injector by flanges.
There is a passage in the combination injector to which steam is supplied from
the boiler, and with this passage there is a connecting passage e, indicated by
dotted lines in Fig. 1, which communicates with the passage e, shown in Fig. 3,
which passage c', leads to a seating in the casing a, for a come faced valve, on
the end of a spindle, screwing into a bush, which screws fluid tight into the
casing a stuffing box being formed in this bush for the spindle d', as shown
This
in Fig. 3, the spindle being rotated by a hand wheel &, on its outer end.
valve d, admits steam to or shuts it off from a passage d, formed in the casing to
which a pipe, is coupled leading to the warming apparatus. The passage a³,
from the valve is best seen in Figs. 2 and 3.
From the passage, there is an outlet in the casing a leading to a branch
to which a pipe, is coupled, which pipe goes to a pressure gauge to show the
pressure of steam in the warming apparatus see Figs. 2 and 1.
From the same passage c¹, supplying steam to the valve d, for warming, there
is a branch passage el, to the ports of a cone plug cock c, for supplying steam to
apparatus for applying sand to rails over which the driving wheels of locomotives
have to pass.
The cone of the cock is on one end of a spindle e, and it is held in position in
the casing a, by a ring e, within which a packing gland is formed round the
spindle e, as shown. There is a lever handle e, on the end of the spindle ², for
oscillating it and from this lever handle there is a pointer c. (which also acts as
a stop) which points to an index on the casing which shows when the cock is open
or shut, and if open to what extent.
The cone of the cock o, is tubular in its axis, one end being closed by a screw
plug
From the axis there are two lateral ports-one port, admits steam to the
axis, when it comes opposite a port in communication with the passage e the
other from the axis, when this latter port is opposite a passage e, in the
casing, the steam passes to a valve e", on a stem sliding and being guided in a
hole in a cap oh, screwing fluid tight into the casing a*.
There is a spring e, round the steam of the valve c", to press the valve against
its seating to prevent steam which may leak past the cone plug cock o, when
the steam is shut off from passing to the pipe conveying steam to the sanding
apparatus. From the valve e, there is a passage e, in the casing a, the
terminus of which forms a branch to which the pipe o", is coupled leading to the
sanding apparatus.
There is a groove e', round the cone plug *, opposite one in the casing a the
object of which is to cut off any steam leaking past the cock e, and convey it to a
passage, in the casing seen best in Fig. 2, which goes to a branch with which
a pipe eh, (called the drip pipe) is coupled for conveying away condensed steam
which may leak past the cone cock.

page_text: We will next describe the combined apparatus illustrated by Figs. 5, 6 and 7
for taking steam from the boiler, and supplying it to an injector, and passing
the delivery water and combined steam therefrom to feed the boiler, and also
supplying steam for warming and other purposes.
a, is the flange on the casing a, which unites the apparatus with the boiler,
which flange has a hole a³, in it (see Fig. 7) connected with the steam space of
the boiler and another hole a³, in it which is connected with the feed water pipe
within the boiler.
-
There is a seating formed in the casing aª, for a cone faced valve b', on the
end of a spindle, which is screwed to screw through a bush 63, that can screw
fluid tight into the casing a, this bush forming the packing gland for the
spindle 63, the hand wheel b, for rotating the spindle being upon its exterior end.
This valve , admits steam to or shuts it off from the casing, and from the
valve the steam can pass through a passage at, to the injector with which a branch
from_the_casing aª, is coupled by a pipe 78.
There is another branch passage, on the casing a, to which a pipe g, is
coupled bringing combined steam and water from the injector, which has to pass
a cone valve g, having its seating in the casing a, the stem of which cone valve
being guided in a hollow plug g, screwing fluid tight into the casing and from
this valve there is a passage g³ (see Figs. and 7) to the boiler.
In the casing, there is also a seating for a cone valve h, on the end of a
screwed spindle h', screwing into a bush h², which screws fluid tight into the
casing, this bush also forming a stuffing box for the valve spindle as shown best
in Figs. 5 and 6, the spindle being rotated by a hand wheel h³, on the outer end
of the spindle.
Steam from the boiler passes from the hole, in the flange by a passage aº,
and then after passing the valve h, it goes along a passage to the branch from
the casing with which a pipe h, is coupled conveying it to the warming apparatus
or to apparatus for other purposes.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
.
1. The combination with a combination injector of valve apparatus and passage
and a pipe for supplying steam to apparatus for warming purposes, substantially
as hereinbefore described and illustrated by Figs. 1, 2 and 3 of the drawings.
2. The combination with a combination injector of valve apparatus for both
supplying steam to warming apparatus and for sanding apparatus, substantially
as herein before described and illustrated by Figs. 1, 2, 3 and 4 of the drawings.
3. The combination and arrangement of valve apparatus for supplying steam
from a boiler to injector apparatus, and conveying the combined water and steam
to the boiler, and for supplying steam for warming and other purposes substan-
tially as hereinbefore described and illustrated by Figs. 5. 6 and 7 of the drawings.
