IMPROVEMENTS IN THE PROCESS OF MANUFACTURING RAILWAY AXLE OR OTHER GREASE, AND IN PLANT OR APPARATUS APPLICABLE THEREFOR to be as follows:
Year: 1884

page_text: We, MARK WILLIAM HYDES, and JOHN HUBERT WILLIAMS, both of five and six
City buildings, Old Hall Street, Liverpool, in the County of Lancaster, Oil,
tallow and lard refiners, do hereby declare the nature of our said invention for
"IMPROVEMENTS IN THE PROCESS OF MANUFACTURING RAILWAY AXLE OR OTHER
GREASE, AND IN PLANT OR APPARATUS APPLICABLE THEREFOR to be as follows:-
"
The making of railway grease, and the rendering of tallow at the present time is
performed mostly in vats, in which a steam pipe dips down and emits steam at one
side, and the material is kept stirred so as to bring all portions into repeated
contact with the steam. Now we form our pan with a central injecting steam
nozzle, rising preferably about one inch above the pan bottom, and covered by a
dome perforated with numerous small holes to within a few inches of the bottom.
By this means a direct vertical impact and thorough stirring on all sides alike is
automatically performed. The dome is screwed down by means of lugs and screws
or their equivalents, so that it can be at once dismounted when required. The
dome is left unperforated near the bottom, so as to allow of a quiet settling place
for dirt, and at this point is the blow-off cock. The delivery pipe however is
placed round the steam jet and has a cock upon it; preferably opened and shut by
differential or slow motion so that the opening can be exactly regulated. Below
the cock we place a horizontally swivelling or universal joint on the pipe, and
beyond that an elbow and continuation pipe, so that the grease or tallow can be
run as required into any of a series of vats on the floor below.
The grease made in the above manner is apt to be too contaminated, with water
formed from the condensed steam; we therefore surround the pan with a super
heated steam jacket to dry the grease, and introduce the super-heaved steam at the
top of the jacket vertically downward to prevent the steam from impinging direct
on one part of the pan and thus unduly heating that part. The pan we form with
graduations on the sides beginning with zero at the bottom so as to measure the
quantities of each material as it is run in, in succession. The control dials of the
super heated steam admission, ordinary steam admission blow off cock et cetera are
all preferably brought to one plate so that a person standing by that plate and
working the handles can regulate the working of the apparatus.
The pan is
preferably hung by means of four angle irons rivetted to the pan seated on cross

page_text: beams, and a pit is suspended or constructed a few feet below the edge of the pan,
50 that the attendants can work therein without any fear of their slipping and
falling into the pan as they might do if their centres of gravity were above the
level of the pan top.
-
The manner of using this apparatus is as follows:-
The various materials used are run in, the amounts required being at once read
off on the graduation and the admission of any given material stopped the moment
the materials rise to the indicated amount. Steam is now turned on and the
superheated steam admitted soon after to the jacket. When the stuff is done, it is
run out into the vats below, and a fresh supply of raw materials run in, the super-
heated and ordinary steam supplies being both exactly regulatable the temperature
is always under perfect control and the amount of evaporation can always be
ascertained by the height the material stands on the graduated scale.

page_text: We, MARK WILLIAM HYDES and JOHN HUBERT WILLIAMS, both of five and six
City Buildings, Old Hall Street, Liverpool, in the County of Lancaster, Oil,
tallow and lard refiners, do hereby declare the nature of our said invention for
"IMPROVEMENTS IN THE PROCESS OF MANUFACTURING RAILWAY AXLE OR OTHER
GREASE, AND IN PLANT OR APPARATUS APPLICABLE THEREFOR," and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:—
The making of railway grease, and the rendering of tallow at the present time is
performed mostly in vats in which a steam pipe dips down, and emits steam at one
side, and the material is kept stirred, so as to bring all portions into repeated
contact with the steam.
The invention is best described by the accompanying drawings, in which:
A is the pan B central projecting steam nozzle rising preferably an inch above
the pan bottom, and covered by a dome C perforated with numerous small holes to
within a few inches of the bottom. By this means a direct vertical impact
thoroughly combining and stirring the ingredients on all sides alike is automatically
performed. The dome is screwed down by means of lugs and screws or their
equivalents so that it can be at once dismounted when required. The dome is left
unperforated near the bottom, so as to allow of a quiet settling place for dirt, and
at this point is the blow-off cock.. The delivery or discharge pipe D however is
placed round the steam jet, and has a cock E upon it, preferably opened and shut
by differential or slow motion so that the opening can be exactly regulated.
A chain is shown by means of which it can be worked from the ground floor.
Below the cock, is placed a horizontally swivelling or universal joint F on the pipe,
and beyond that an elbow G, and continuation pipe G¹ with a rose or sieve Gat
the end, from which the grease or tallow can be run, as required into any of a
series of vats or coolers I on the floor below. A perforated pipe H is placed
round the top edge, of the pan from which a spray of cold water may be projected,
onto the top of the material in the pan and over boiling is thereby prevented.
In order to drive off the excess of water formed by the condensation of the steam,
the pan is surrounded with a superheated steam jacket J, the superheated steam is
introduced at the top of the jacket at K, by a pipe passing vertically downward to
prevent the steam from impinging direct on one part of the pan, and thus unduly
heating that part. The pan we form with graduations as shown on the sides
beginning with zero at the bottom, this graduated scale is used first, to measure the
water necessary for proposed quantity of grease and afterwards for gauging the
proportionate quantity of finished material.
In control dials of the superheated steam admission, ordinary steam admission,
blow off cock, etcetera are all preferably brought to one plate L, so that a person
standing by that plate and working the handles can regulate the working of the
apparatus. The pan is preferably hung by means of four angle irons M riveted to

page_text: the pan, seated on cross beams N and a pit P is suspended or constructed a few
feet below the edge of the pan, so that the attendants can work therein, without
any fear of their slipping and falling into the pan, as they might do if their centres
of gravity were above the level of the pan top.
The manner of using this apparatus is as follows:-
The various materials used are run or tipped in the pan after the quantity of
water required has been run in as shown by the graduated scale. The other
materials may have been previously weighed or measured or the amount may be
judged by the graduated scale.
Steam is now turned on, and the superheated steam admitted soon after to the
jacket. When the stuff is done it is run out into the vats below, and a fresh
supply of raw materials introduced, the superheated and ordinary steam supplies
being both exactly regulatable, the temperature is always under perfect control,
and the amount of evaporation can always be ascertained by the height the
material stands on the graduated scale.
. 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
1st. The manufacture and use of apparatus or plant for manufacturing railway
axle or other grease, constructed and combined substantially as herein described;
the entire control centred on dial plate with handles, opening and showing all pipes
connected herewith under hand of operator.
2nd. The following several parts for the purposes described, each substantially
as and for the purposes described. (a) The jacketed pan preferably graduated to
show the contents at each height. (b) The central rose in combination with such a
pan (c) The swivelling joint and swinging pipe for discharging the contents of
the pan into any of several vats placed below. (d) In conjunction with such
jacketed vat the vertical admission steam pipe. (e) The combination of the main
pit containing tanks, the suspended pan above, and the suspended working floor a
few feet below the top. (f) The arrangement of pan suspended on beams at top;
and lastly, the dial plate for centralizing control, all arranged with handles
operating the various pipes connected with the rendering pan so that the working
can all be conducted from the same point.
