IMPROVEMENTS IN MACHINERY FOR MAKING RETORTS AND OTHER SIMILAR ARTICLES. FROM CLAY
Year: 1884

page_text: We WILLIAM PORRITT INGHAM of Queens Square Middlesbrough on Tees in
the North Riding of the County of York, Engineer, and ALFRED CLAYTON HILL
of the same place, Engineer, do hereby declare the nature of said invention for
"IMPROVEMENTS IN MACHINERY FOR MAKING RETORTS AND OTHER SIMILAR ARTICLES.
FROM CLAY" to be as follows :-
:
In the specification of a former patent granted to us under date the 19th February
1876 N° 712 is described a machine for making retorts and other similar articles
from clay comprising a motive power cylinder and a clay chamber or cylinder each
containing a piston and the two pistons being connected by a piston rod or rods.
Attached to the piston in the motive power cylinder is another rod which passes
through the top cover thereof in the usual way with gland and stuffing box. This
piston rod is connected by a cross head to and actuates a lever or levers, which is
or are connected to another or other lever or levers by a rod or rods. One end of
this or these lever or levers is or are connected to a weigh bar or bars, which is or
are secured to the ground or to the wall of the building in which the apparatus is
placed, the other end or ends being connected to a plate or frame of suitable form:
and dimensions for the reception of the retort or other article. These levers are
so arranged that by altering the position of the connecting rod or rods between
them the plate or frame is made to travel at any relative speed to the pistons, as
may be necessary or expedient for carrying or holding up the retort or other
article as it is being made.
Now according to our present invention we dispense with the rod or rods
whereby the levers are connected as described and shewn in the specification of
our said patent and we connect the said levers by a rope made of suitable material
and which works round pullies or wheels that are attached to the levers; the rope
or chain passing then to a winch attached to the lower lever or levers. By this
invention the plate or frame for receiving the retort or moulded article can be more
readily put into any desired position and the retort or other moulded article, after
being made can be more easily lowered on to a bogie or carriage. Moreover, by
the use of a rope or chain and winch as described we obviate having to disconnect
the levers every time a retort or other article is made.

do hereby declare the nature of said invention for "IMPROVEMENTS IN MACHINERY

manner the same is to be performed to be particularly described and ascertained
in and by the following statement:-
In the specification of a former patent granted to us under date 19th February
1876 N° 712 is described a machine for making retorts and other similar articles
from clay comprising a motive power cylinder and a clay chamber or cylinder each
containing a piston and the two pistons being connected by a piston rod or rods.
Attached to the piston in the motive power cylinder is another rod which passes
through the top cover thereof in the usual way with gland and stuffing box. This
piston rod is connected by a crosshead to and actuates a lever or levers which is or
are connected to another or other lever or levers by a rod or rods. One end of
this or these lever or levers is or are connected to a weigh bar or bars which is or
are secured to the ground or to the wall of the building in which the apparatus is
placed, the other end or ends being connected to a plate or frame of suitable form

arranged that by altering the position of the connecting rod or rods between them
the plate or frame is made to travel at any relative speed to the pistons as may be
necessary or expedient for carrying or holding up the retort or other article as it
is being made.
"
Now according to our present invention we dispense with the rod or rods whereby
the levers are connected as described and shown in the specification of our said
patent and we connect the said lever by a rope or chain made of suitable material
and which works round pulleys or wheels that are attached to the levers; the rope
or chain passing thence to a winch attached to the lower lever or levers. By this
invention the plate or frame for receiving the retort or moulded article can be
more readily put into any desired position and the retort or other moulded article,
after being made can be more easily lowered on to a bogie or carriage. Moreover
by the use of a rope or chain and winch as described we obviate having to
disconnect the levers every time a retort or other article is made.
Referring to the accompanying sheet of drawings Fig 1 is a side elevation and
Fig 2 is a back or rear view of a machine embodying our present invention, Fig 3
is a plan or top view of the same.
Like letters of reference indicate similar parts in the several figures.
a is the top or motive power cylinder; b the clay chamber or cylinder; c the
piston rod passing through the top cover of the cylinder a and connected to the
upper levere by the crosshead d; e, e¹ the lower levers supporting the table or
plate h for the reception of the retort or other article; g, g the weigh bars connected
to and supporting one end of each of the levers e, e¹ and i, i the guides for the
table or plate h all as described and shown in our said former specification and for
the purposes therein set forth. j is the rope or flexible connection between the
levers e, e¹ according to our present invention; one of its ends is connected to the
cross frame or support k secured to the lower levers e¹ whilst its other end is
connected to the winch barrel or drum 1 carried by those levers and which is
provided with a handle for rotating it. The rope or flexible connection ; passing
from the cross frame or support k upward and over a sheave or pulley m pivotted

page_text: in a frame k carried by the upper lever e, it then passes downward and under a
second pulley or sheaven carried by the cross frame or support & and thence to the
winch barrel or drum l. The frames or supports k, k¹ are made adjustable
respectively on the levers e¹ and e, in order that any desired relative movement
between the said levers e, e¹ and consequently between the piston in the clay
cylinder 6 and the plate or frame h may take place, as will be readily understood
thereby regulating the speed or travel of the said plate or frame h according to the
nature of the work in hand.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, we declare that what
we claim is
In a machine for making retorts or other similar articles from clay the combination
with a motive power cylinder, a clay cylinder, levers such as e, e¹ and a plate or
table h to receive the articles moulded of a connecting rope or chain (or ropes or
chains) pullies or sheaves, such as m n and a winch barrel or drum for adjusting
the travel of the plate or table substantially in the manner hereinbefore described.
Dated this 4th day of November 1884.
