Improvements in and relating to Steam Traps.
EDWARD JAMES MOORE North Lodge, Cane Hill, Purley, Surrey in the
Parish of Coulsdon Engineer, do hereby declare the nature of this invention to be
as follows
-
An invention for the better working of steam traps, whereby the steam from
pipes is made to pass through a perforated sheet of metal before entering the steam
tiap and by so doing leaves all deposit in the resei voir at bottom, which may be
periodically emptied, or a steam cock may be attached to bottom of reservoir
whereby all matter may be blown out.
The accompanying diawing shows proposed steam filter in its proportions of a
quarter senle but these may vary in size and proportions as may be deemed
necessary to cope with amount of steam passing through from runs to traps
Fig. 1 shows a side view of steam filter as it would appear ready for fixing

Improvements in and relating to Steam Traps.
I, EDWARD JAMES MOORE, of North Lodge, Cane Hill, Purley, in the County
of Surrey, 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 relates to micans for separating sedimentary or other foreign
matter from steam before it enters the ordinary steam traps.

page_text: The invention 18 illustrated in the drawings accompanying my Provisional
Specification whorem Figs. 1 and 2 are respectively side and sectional elevations,
and Figs. 3 to 8 shew detached detail views of the various parts. The same letters
of reference where they occur are used to denoto corresponding parts in the several
figures.
The device forms a sediment intercepting tiap or chamber through which the
steam is led on its way to the ordinary steam trap. A is the body having an inlet
and an outlet and tapped at top and bottom for the cap B and sediment collecting
reservoir C. The body A is internally shouldered as shewn in Fig. 2, o is
provided with ledges, so as to form a seating for the sediment anester E which
is preferably a perforated disc of metal see Fig. 7. D 18 a distance piece or frame,
shewn in plan and elevation in Figs. 5 and 6 respectively, preferably made in the
form of a skeleton cylinder which lies loose on the top of the perforated arrester E
and between it and the lower end of the cap B and serves to keep the anester E
on its seat while affording full way for the steam which passes in the direction of
the arrows shewn in Fig. 2.
The cap B is sufficiently large to allow of both parts D and E being taken out
and replaced by new ones if found necessary a a represent asbestos joint rings.
The inlet of the sediment intercepting tiap is connected to the sei vice or coils
and the outlet is connected to the ordinary steam traps
The steam in its passage
through the device is compelled to pass through the perforated arrester E which is
of sufficiently fine mesh to intercept the sedimentary or other foreign matter which
the steam may contain and which would otherwise pass into the ordinary steain
traps. The sediment falls into the reservoir C underneath from whence it may be
periodically emptied out, or a steam cock may be attached to the bottom of the
reservoir for blowing off the deposit therefiom.
I wish it to be understood that the invention is not restricted to the form
described with reference to the accompanying drawings which are furnished
as an illustration of a convenient form in which the invention may be carried into
practical effect.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is,-
-
Menns for separating sedimentary or other foreign matter from steam consisting
of an intercepting tiap or chamber having steam inlet and outlet pipes foi connection
respectively to the service or coils and the ordinary steam traps, and a perforated
disc contained in said intercepting trap or chamber through which the steam is
constrained to pass and by which the sedimentary or other foreign particles are
separated substantially as described.
