page_text: LETTERS PATENT to Edwin Travis, of Oldham, in the County of Lancaster,
and Joseph Louis Casartelli, of the City of Manchester, in the said
County, for the Invention. of "AN IMPROVED APPARATUS FOR REGULATING
PROVISIONAL SPECIFICATION left by the said Edwin Travis and Joseph
Louis Casartelli at the Office of the Commissioners of Patents, with
their Petition, on the 23rd May 1857.
We, EDWIN TRAVIS, of Oldham, in the County of Lancaster, and JOSEPH
LOUIS CASARTELLI, of the City of Manchester, in the said County, do hereby
declare the nature of the said Invention for "AN IMPROVED APPARATUS FOR
REGULATING THE SUPPLY AND DISCHARGE OF STEAM. AIR, WATER, AND OTHER
FLUIDS," to be as follows:-
We make a box of brass or other suitable anti-corrosive metal or material
with a slide tube at one end, an adjusting plug, piston, or valve at the other,.
and an escape tap or hole at the side, which forms a simple and efficient

page_text: apparatus for regulating the supply and discharge of steam, air, water, and
other fluids. We fix the said apparatus to the end of an additional pipe, which
is attached to the ordinary steam pipe or other vessel on which it is intended
to act, forming one continuous tube. We give the said additional pipe a
compensating arrangement by bend, coil, or disc, or other similar agency, or
we provide a compensating arrangement with the apparatus itself, by spring
or other mechanical contrivance. We also make it with a swivel or universal
centre to allow for any vibration or divergence of the connection to the sliding
tube. When steam begins to escape through the tap on hole, and the
additional pipe becomes heated and expanded, we adjust the plug, piston, or
valve, so as to stop the escape of steam; and when it cools the contraction of
the metal pipe will draw the sliding tube from the piston and cause it to open,
and thus allow any condensed steam or water to escape. We also make the
said apparatus so that by transposing the sliding tube and the plug, piston,
or valve, it may be used for right or left hand. We are aware that the
contraction and expansion of a metal pipe in a straight form has been used
for some purposes, but not in a manner or in combination with the arrange-
ment herein described.
SPECIFICATION filed in pursuance of the conditions of the Letters Patent,
and of an Order of the Lord Chancellor, by the said Edwin Travis and
Joseph Louis Casartelli in the Great Seal Patent Office on the 21st
December 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, EDWIN
TRAVIS, of Oldham, in the County of Lancaster, and JOSEPH LOUIS CASARTELLI,
of the City of Manchester, in the said County, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-third day of May, in the year of our Lord
One thousand eight hundred and fifty-seven, in the twentieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Edwin Travis and Joseph Louis Casartelli, Her special licence that we,
the said Edwin Travis and Joseph Louis Casartelli, our executors, administra-
tors, and assigns, or such others as we, the said Edwin Travis and Joseph
Louis Casartelli, our executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times thereafter during
the term therein expressed, should and lawfully might make,use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel

page_text: Islands, and Isle of Man, an Invention for "AN IMPROVED APPARATUS FOR
REGULATING THE SUPPLY AND DISCHARGE OF STEAM, AIR, WATER, AND OTHER
FLUIDS," upon the condition (amongst others) that we, the said Edwin Travis
and Joseph Louis Casartelli, by an instrument in writing under our hands
and seals, or under the hand and seal of one of us, should particularly
describe and ascertain the nature of the said Invention, and in what manner
the same was to be performed, and cause the same to be filed in the Great
Seal Patent Office on or before the Twenty-second day of December next
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Edwin Travis and Joseph Louis
Casartelli, do hereby declare the nature of our said Invention, and the
manner in which the same is to be performed, to be particularly described
and ascertained in and by the following statement (that is to say):-
We make a box of brass or other suitable anti-corrosive metal or material
with a slide tube at one end, an adjusting plug, piston, or valve at the other,
and an escape tap or hole at the side, which forms a simple and efficient
apparatus for regulating the supply and discharge of steam, air, water, and
other fluids, which we call or name a "steam trap."
We fix this apparatus
to the end of an additional pipe, which is attached to the ordinary steam pipe
or other vessel on which it is intended to act, forming one continuous tube.
We give the said additional pipe a compensating arrangement with itself by
bend, coil, disc, or other similar agency, to act when the pressure of the steam
exceeds the point at which the apparatus was adjusted. Or, we provide a
compensating arrangement with the apparatus, by spring or other mechanical
contrivance. We also make the said apparatus with a swivel or universal
centre to enable it to accommodate itself to any vibration or divergence of
the connection to the sliding tube, or we simply screw the apparatus to a wall
or other convenient place, so that when the steam is first raised, it will force
the air or fluid through the ordinary pipe into the additional pipe, which will
then escape through the escape tap or hole. As soon as the steam begins to
escape through the said hole or tap, and the additional pipe becomes heated
by the steam and expanded, we adjust the plug, pistou, or valve, so as to stop
the escape of steam, and when it cools the contraction of the metal pipe will
draw the sliding tube from the piston, plug, or valve, and cause it to open,
thus allowing any condensed steam or water to escape, or it may be applied
directly to any range of piping, and thus dispense with the additional pipe.
We also chamber the inside of the trap to allow the free discharge of the air
or fluid from: the tube and outlet, and to an adjusting piston, plug, or valve

page_text: we apply a spring, if found necessary for the purpose of compensating for
any additional expansion after it has been adjusted; but the trap will act
efficiently, either with or without the spring.
We make the trap or apparatus in such manner that by transposing the
sliding tube, and the plug, piston, or valve, it may be used for right hand
or left hand.
The manner in which our said Invention is to be performed will be clearly
understood by reference to the accompanying two Sheets of Drawings, and the
letters of reference thereon, in which Fig. 1, Sheet 1, is a view of the box or
body of the trap; Fig. 2, a section thereof; Fig. 3, a view of the same with
the compensating arrangement and universal centre; and Fig. 4, a section
thereof; and it must be observed that the compensating arrangement is
applicable to Figs. 1 and 2, as well as Figs. 3 and 4, although not shewn.
Iu these Figures A represents the box or body of the trap, a the brackets for
fixing the box in its place; b, the sliding tube; c, the adjusting piston, plug,
or valve; d, the outlet; e, the moveable cap screwed on the end of the
apparatus; ff, the binding or lock nuts; g, an universal fixing or centre;
h, a spring for keeping the body of the apparatus in its place; i; the
connection with the expanding pipe; and k, the compensating spring inside
the trap.
In Sheet 2, Figs. 1 and 2 shew a plain or curved disc compensation for
the supply and discharge, in which a represents the box; b, the elastic disc
or spring, which is held between the flanges which form the box; c, the
expanding pipe; and d, the pipe to which the sliding tube is attached. On
this Sheet 2 are also shewn various or different bends as compensating
arrangements, though any kind or degree of bend may be used for the
purpose.
It will be evident that our improved steam trap is applicable, first, to all
kinds of steam or vapour pipes used as conduit pipes for conveying steam
from one vessel to another where condensation of steam or vapour is liable to
take place.
Secondly, to pipes from steam generators to other vessels and receivers, for
whatever purpose steam or vapour may be used, either directly or indirectly,
either for mechanical power, for heating, drying, evaporating, condensing,
boiling, digesting, or liquifying.
Thirdly, to all receivers where steam or vapour is wholly or partially con-
densed and desired to be carried off, whether such vessels be in connection
with pipes and receivers or not.

page_text: Fourthly, to all pipes, receivers, or vessels for the discharge of air formed
by steam or vapour, where it is necessary or desirable to discharge such
air, without at the same time allowing the uncondensed steam or vapour
to escape.
Fifthly, for regulating the supply of steam or vapour to pipes, receivers,
or vessels used for any purpose where uniform pressure or quantity is required.
Sixthly, to pipes and vessels conveying steam from boilers or generators to
engines, and to the cylinders of steam engines of high or low pressure,
whether the same be stationary, portable, locomotive, or marine. To pipes
and vessels for warming or heating private or public buildings, churches,
mills, or warehouses, and for ventilating mines. To cylinders and vessels used
for drying yarns, fabrics, or fibrous materials in the process of manufacture,
or in finishing, drying, and printing the same, and in the manufacture of
paper, felt, and other substances. To pipes and vessels used in boiling and
refining sugar, brewing, distilling, cooking, evaporating pans, and other
similar purposes.
Having thus fully described the nature of our said Invention, and the
manner in which the same is to be performed, we desire it to be distinctly
understood, that we do not confine ourselves to the exact details herein set
forth, as such may be varied or modified without departing from the principle
thereof;
neither do we claim the mere contraction and expansion of a metal
pipe, as we are aware that such has been used in a straight form for some
purposes, but not in the manner or in combination with the arrangements
herein described; but we claim as our Invention, and which, to the best of
our knowledge and belief, has not been hitherto used within the realm,-
First, the sliding tube separate from the expanding tube.
Secondly, the peculiar arrangement of the adjusting piston, plug, or
valve, with or without a spring.
Thirdly, the arrangement for reversing the ends of the trap from right to
left, or vice versa.
Fourthly, an universal centre for fixing the apparatus, so as to allow it
to accommodate itself to any vibration or divergence of the connection to
the sliding tube.
Fifthly, the auxiliary expanding tube in a straight form in connection
with the said combination.
Sixthly, the compensating arrangement in connection with the plug,
piston, or valve.
Seventhly, the auxiliary expanding tube, with compensating arrangement
with itself by bend, disc, coil, or other agency.

page_text: And, eighthly, the peculiar arrangement, construction, and combination of
the several parts of the said apparatus, and the application of the same to
and for the purposes herein described, and illustrated in the accompanying
two Sheets of Drawings.

In witness whereof, we, the said Edwin Travis and Joseph Louis
Casartelli, have hereunto set our hands and seals, this Eighteenth
day of December, in the year of our Lord One thousand eight
- hundred and fifty-seven.
