PROVISIONAL SPECIFICATION.
Improvements in Means and Apparatus for Refining Paraffine.
We, JAMES BAXTER, and WILLIAM BAXTER, of 1 Farady Place, Addiewell,
West Calder, Scotland, Engineers do hereby declare the nature of this inven-
tion to be as follows:
Our invention relates to improvements in means and apparatus for refining
paraffine, which consists of a mechanical contrivance for the cakes of paraffine
to be placed on their edge inside perforated cases, these said cases are fixed to
a carriage which run on wheels each case being arranged with a space between
to allow the heat to get at both sides of each cake.
The carriages are connected together with an endless pitch chain which is
passed round notched wheels placed at a suitable distance apart, these said wheels
being fixed to separate shafts and mounted on bearings. By giving motion_to
one of the wheels by means of hand or mechanical power the carriages revolve
round the wheels on the endless pitch chain and deposit the finished paraffine
into a tank placed below. At the same time the cases that have been exhausted
of its contents are coming up round the follower and are recharged with paraffine
and carried forward into position to be operated on in a like manner.
The object of our invention is to place the paraffine cakes on their edge which
allows the impure matter to discharge from both sides of the cakes.
It will be understood that the foregoing is given by way of illustration, and
that the materials and shapes may be varied in many ways within the scope of
our invention.

COMPLETE SPECIFICATION.
Improvements in Means and Apparatus for Refining Paraffine.
We, JAMES BAXTER, and WILLIAM BAXTER, of 1 Farady Place, Addiewell,
West Calder, Scotland, Engineers, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
Our invention relates to improvements in means and apparatus for refining
paraffine, which consists of a mechanical contrivance for the cakes of paraffine to
be placed on their edge inside perforated cases, these said cases are fixed to a
carriage which run on wheels each case being arranged with a space between to
allow the heat to get at both sides of each cake.
We attain these objects by the mechanism illustrated in the accompanying
drawings, in which-
Fig. 1 is a side elevation ;
Fig. 2, is a plan
Fig. 3, is the end elevation.
Similar letters refer to similar parts throughout the several views.
The carriages a¹ and a are connected together with an endless pitch chain g
which is passed round notched wheels e, e, placed at a suitable distance apart, these
said wheels being fixed to separate shafts,f, and mounted on bearings on a frame
mounted on pillars i. By giving motion to one of the wheels e by means of hand
or mechanical power the carriages a¹ and a² revolve round the wheels e, e, on the

At the same time the cases a between the spaces c in the carriages a' that have
been exhausted of its contents are coming up round the follower and are recharged
with paraffine and carried forward into position to be operated on in a like manner.
Each of the carriages a¹ and a² are supplied with four wheels & these said wheels
travel on rails d. A saucer is fixed beneath the carriages to catch the impure
matter which passes away through the outlet p. Steam pipes are fitted up in the
various positions indicated in Figs. 1, and 3, with the steam inlet 7 at or near the
top, the said steam passing through the pipes and out by valve m or through
another valve m' and down the pipe n into the pipes in the finished product tankk
and out by the exhaust o. The whole of the apparatus is erected on and embedded
in brickwork h.
q
In this invention the cake or cakes of paraffine are placed on their edge inside of
a wire cloth case or cases a which may be lined with canvas or without the
aforesaid canvas. The case or cases a are secured to a carriage or carriages a
and a², and arranged with a space c between each of the cases a, to allow the heat
to act direct on the side of each cake or cakes of paraffine. The carriages run
on wheels balong rails or guides at each side, top and bottom. The carriages a
and a² are connected together by an endless pitch chain g or chains, which are
passed round wheels e and by giving motion at either end of the shaft the cases
revolve around the wheels e and the pleasure of the operator and deposit the
finished product itself into the finished product tank k at the base, and at the same
time the cases that have emptied themselves are coming up and is refilled with
paraffine and carried forward into position to be operated on as hereinbefore
described. The apparatus may be constructed to hold any number of cakes.
In placing the cake or cakes of paraffine on their edge it alters the position
of the crystals from the horizontal to the perpendicular, and on applying heat
assisted by the weight of the paraffine itself, allows the impure matter to flow
out freely at both sides. The advantages are in sweating from both sides of
each cake or cakes to allow the impure matter to flow outwards freely from both
sides of each cake or cakes, thereby giving a better result than has hitherto
been obtained by any apparatus or process now in common use.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is :-
1. The combination of the apparatus for refining paraffine by the action of heat,
substantially as herein described and according to Figs. 1, 2, and 3, of the accom-
panying drawings.
2. In an apparatus for refining paraffine, the combination of the cases a
carriages a¹ and a², wheels 6 spaces with rails d notched wheels e shafts pitch
chain 9 piers and pillars i, with the saucer tankk steam pipes l, n, and o, inlet
valves m, and m' and the exhaust o, substantially as herein described and according
to the accompanying drawings.
3. The combination of the apparatus to be constructed of any material, size, or
with any modifications of the various parts, substantially as described and for the
purpose set forth.
