Year: 1884

page_text: PROVISIONAL SPECIFICATION.
We, JOHN MAYNES of N° 55 Myddleton Square London, E.C. and CHARLES
LEESE WATCHURST of No 33 Blessington Road, Lee, in the county of Kent,
Engineers do hereby declare the nature of our invention for IMPROVEMENTS IN
THE CONSTRUCTION OF ROLLERS FOR POWER LOOMS, CARDING ENGINES, AND
STRETCHING FRAMES, to be as follows:-
Our invention relates to improvements in the construction of rollers or cylinders
used in power looms, carding engines, and stretching frames, which have clothing
wrapped round them, as metallic surfacing in taking-up rollers for power looms, and
card cloth in carding engine cylinders.
In carrying out our invention we preferably form the barrel or body of our
improved roller of several pieces or segments of thin sheet metal stamped to a
curved form with the edges turned inwards like a flange, which segments when put
together form a cylinder, the internal flangos making an abutment which prevents
the segments from falling inwards. One or more rings are now put onto the
outside of the barrel into recessos stamped for the purpose, which holds it firmly
together.
Instead of making up the barrel of segments as above described, it may be
made of thin tube or of thin metal sheet or strip rolled or wound up into a
cylindrical form,
:
On the surface of the barrel constructed as above described we punch a number
of holes leaving the piece punched away still attached to the surface by one side of
it, this piece stands out on the inner surface of the cylinder or barrel. Bars of
wood are thon put along the inner side of the surface of the barrel, and the pieces
of metal previously left standing up are turned down over the bars firmly fixing
them in their places. As viewed then on the outer surface of the barrel the wood
will be seen closing up the spaces where the holes had been previously punched.
When the metallic surfacing, card cloth, or other covering is put onto the roller it
is nailed or otherwise fastened down onto these wooden bars.
The wooden bars being now in their places on the inner surface of the barrel,
ends carrying pivots or mandrils are fixed onto the barrel. These ends are made
of thin metal stamped or cast in a dished-out or other form, into which the pivots
or mandrils are fastened. The outer edge of these ends has a register or groove
formed in them, which fits into a corresponding register or groove formed in the
ends of the barrel previously described, so that when the dished-out ends are put
into or shrunk onto the onds of the barrel, the registers or grooves fit into each
other and the ends are thereby firmly fastened to the barrel.

Engineers do hereby declare the nature of our invention for IMPROVEMENTS IN
THE CONSTRUCTION OF ROLLERS FOR POWER LOOMS, CARDING ENGINES AND
STRETCHING FRAMES, 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 the construction of rollers or cylinders
used in power looms; carding engines and stretching frames, which have clothing
wrapped round them such as metallic pierced surfacing or taking-up rollers for
power looms, and card cloth on carding engine cylinders.
Our invention consists in making the barrel or body of the roller of thin sheet
iron or othor suitable metal which is made into a cylindrical form by joining up
segments or rolling up strips of the metal as may be preferred, ends carrying the
pivots are made in a dished-out or rounded form by being stamped or spun and
are then put on either end of the barrel. Wooden bars are put along the inner
surface of the barrel or body of the roller in a line with holes previously made in it.
This completes the roller or cylinder on which the metallic surfacing or card cloth
is fastened in the usual manner.
.
In order that our invention may be more readily understood we have illustrated
it in the accompanying Drawing reference in detail being made thereto in the
following description:
Three rollers or cylinders are shewn in Figs 1. 2. 3, the left hand part of each of
these figures being shewn in longitudinal section, and the right hand part of each
being in elevation.
Fig 3a is a portion of the surface of the barrel of the roller shewn in Fig 3.
Fig 4 is a transverse section of the barrel of the roller shewn in Fig 2.
Fig 5 is a front view of the dished-out ends of the roller.
Fig 6 is a longitudinal section of one end of a roller shewing a plate for
steadying the pivot.
In all the figures the same letters have reference to the same parts.
In carrying out our invention we preferably form the barrel or body a a a
Figs 1. 2. 3 of the roller of several pieces or segments b, b, Figs 2. 4 of thin sheet
metal stamped or rolled to a curved form with the edges c, c, Figs 2. 4 turned
inwards like a flange. In the roller shewn in Figs 2.4 three segments are by
preference used, but we do not confine ourselves to this or any number, each of
them when stamped up being in section of the form of the one-third of a circle.
The edges c, c, are turned inwards along the line of the radius of the circle of the
roller or cylinder so that when the segments b, b, b, are put together they form a
cylinder or barrel a Fig 2, the internal flanges c c forming also an abutment which
prevents the segments from falling inwards. When the segments are thus put

page_text: together the joints at the flanges are soldered or brazed together. One or more
rings d d may now be put or shrunk on the barrel on the outside for the purpose
of binding it firmly together. Recesses or depressions are stamped in the
barrel a to receive the rings d d so as to leave the surface of the barrel level.
Instead of making up the barrel of segments as above described it may be made
if preferred of thin tube Fig 1, or of thin metal sheet or strip rolled or wound up
into a cylindrical form Fig 3.
In Fig 1 the barrel a is formed of thin metal tube b¹ which needs no further
description.
In Fig 3 the barrel a is made by a thin and narrow metal sheet or strip bª ¿ª
being wound up in a spiral or screw like form by which means a cylinder is formed.
Projections ff and depressions with small slots g g are formed on the sides of the
strip 6 6 and when these projections and slots come together on two adjoining
coils of the strip the projection is put through the slot and turned over or clenched
as shewn at Figs 3. 3a, h h. By this means a cylinder is formed and firmly
bound together.
Corrugations r r and register grooves 8 a are formed by means of stamping or in
any other convenient manner on either end of the barrel or of the parts forming it
for the purpose hereafter described.
In the surface of the roller a a a formed in any of the above ways a number of
holes ii as shewn in Figs 2. 4 are punched leaving the piece k k punched inwards,
still attached to the barrel by one side of it, this piece projecting or standing out on
the inner surface of the barrel or cylinder.
Bars of wood, 1, 1, by preference three in number, and of a triangular or other
suitable section are then put along the inner side of the surface of the barrel and
the pieces of metal previously left standing up are turned down over the bar k k
Fig 4, firmly fixing it in its place.
As viowed then on the outer surface of the barrel the wood of the bars will be
scen closing and filling up the spaces where the holes had been previously punched.
These holes are so spaced as to suit the metallic pierced surfacing, card cloth, or
other covering which is put onto the roller, this covering being nailed, or otherwise
fastened down onto these wood bars in the usual and ordinary manner.
When the wood bars have been put in the barrel, ends o o Fig 5 carrying pivots
or mandrils p p are fixed onto either end of the barrel a a a.
These ends.o o are made of thin metal cast stamped or spun in a dished-out or
other convenient form, into which the pivots or mandrils p p are fastened. These
dished-out ends oo may be shrunk onto the pivots p p and then a part of the
surface of the end may be forced into a depression t t Figs 2. 5 formed in the pivot
thus keying them together, or the fastening may be effected in any convenient or
suitable manner.
The outer edge of these dished-out ends has a register or groove 8' 8' formed in
them, and also a number of corrugations this being done by stamping or in
any other convenient manner, so that when the ends are put or shrunk onto the
barrel the corrugations and register s¹ in the ends enters and fits into
corresponding corrugations rr and register grooves a formed in either end of the
barrel as before described.
By this means the dished-out ends are firmly fastened to the barrel the register
or groove 8 8 preventing the ends from slipping off endways and the corru-
gations serving to key the parts together.
When the ends are put on the barrel the joints formed may be soldered or brazed
if desired.
A plate or bar v Fig 6 is put in the barrel at each end to give steadiness to and
form a bearing for the inner end of the pivot p. This plate or bar v is fastened to
the barrel by means of a part of the barrel being turned down to form a flange vi
to which to secure it, or it may be fastened to the barrel by means of angle pieces,
any convenient manner,
or in
