PROVISIONAL SPECIFICATION.
Improvements in Warp Rollers or Beams.
We, CHARLES URBAIN PLAT, and JOSEPH ALEXANDRE PIERREL, both of
Presles, St. Maurice s/ Moselle, in the Republic of France, Manufacturers, do hereby
declare the nature of this invention to be as follows:-
Our invention relates to warp rollers or beams.
-
The warp rollers or beams heretofore used for weaving and preparatory purposes
are not sufficiently durable and rigid, and this latter quality being indispensable for
the proper movement of the warps in looms. Some of these rollers or beams which
have been made of wood or of cast metal and wood are liable to deformations and
rapid wear; others made either of cast or sheet metal are not more practical by
reason of their excessive weight and their high price which arises from the great
number of small adjusting or fastening parts which they comprise. These rollers
or beams have consequently not progressed beyond the experimental stage and have
not been employed in practice.
In the improved warp roller or beam constructed according to our aforesaid
invention the numerous adjusting or fastening parts heretofore used in the con-
struction of metallic rollers or beams are dispensed with. Our warp roller or
beam possesses as little weight as possible and is absolutely rigid, whilst its price
is such as to enable a really practical use of the same.
In order to render this invention better understood we will describe the same
with reference to the accompanying specimen drawing.

Figure 1 shows a longitudinal section of the extremity of a warp roller or beam
constructed according to our invention.
Figure 2 represents a transverse section on the line 1-2 of Figure 1.
In these figures similar letters of reference designate corresponding parts.
Our improved roller comprises four essential parts, viz. the disc A; the
pulley B the cylinder C; the rod or shaft D.
These four parts are made separately and connected as hereinafter set forth.
The disc A is made of chased sheet steel or other very rigid metal; it is
provided at its centre with a round hole having the same diameter as
cylinder C.
the
The pulley B consists of cast iron and is on the one hand attached to the
said disc by bolts E, and on the other hand to the said cylinder by screws F. By
fastening the aforesaid parts together in this manner absolute rigidity is ensured
to the whole device, but other equivalent means can be employed for the same
purpose.
The pulley B presents a central opening which is somewhat larger than the exact
diameter of the cylinder and can therefore be easily slid upon the latter to place it
in the desired position this having been effected the space G between it and the
outer periphery is filled up with a very fusible metal so as to ensure its absolute
adherence. This metal is indicated in the drawing by crossed section lining.
The cylinder C is made of sheet metal the thickness of which can be varied
according to the strength to be obtained. This cylinder has a longitudinal groove
designed to receive the rod for winding up the threads. At each end of this
cylinder we provide interiorly a reinforce H of cast iron which is firmly attached
to the cylinder without further boring and fastening. A hole is left at the centre
of this reinforce for the passage of the rod or shaft D or for fixing therein by
means of simple screw threads a simple journal or spindle.
The rod or shaft D of iron is hollow, and at its two extremities are provided two
solid journals L.

page_text: As above stated this rod or shaft can be replaced by screw-threaded spinates
fixed in the two ends of the cylinder.
A pressing-screw K can be provided for keeping the cylinder in its place
upon the rod or shaft.
In our mode of constructing warp rollers or beams the adjusting or fastening
parts are dispensed with, and it ensures, besides great lightness, perfect rigidity
and they can be manufactured at a very small cost.
It will be understood that the form and dimensions of the several parts of our
improved warp roller or beam can be varied without departing from the nature of
our invention.
The warp rollers or beans are made to correspond to a given maximum breadth
of surface for the threads. This breadth can be reduced at will for the same roller
or beam by simply moving the discs A. a greater or smaller distance away from the
pulleys B, the latter remaining stationary. This adjustment can be obtained by means
of bolts E having two nuts, the lengths of which can be varied according to the
distance which the said parts are to be separated.

COMPLETE SPECIFICATION.
Improvements in Warp Rollers or Beams.
We, CHARLES URBAIN PLAT, and JOSEPH ALEXANDRE PIERREL, both of
Presles, St. Maurice s/ Moselle, in the Republic of France, Manufacturers, 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:-―
Our invention relates to warp rollers or beams.
The warp rollers or beams heretofore used for weaving and preparatory purposes
are not sufficiently durable and rigid, this latter quality being indispensable for the
proper movement of the warps in looms. Some of these rollers or beams which
have been made of wood or of cast metal and wood are liable to deformation and
rapid wear others made either of cast or sheet metal are not more practical by
reason of their excessive weight, and their high price which arises from the great
number of small adjusting or fastening parts which they comprise. These rollers
or beams have consequently not passed beyond the experimental stage and have
not been employed in practice.
In the improved warp roller or beam constructed according to our aforesaid
invention the numerous adjusting or fastening parts heretofore used in the con-
struction of metallic rollers or beams are dispensed with. Our improved warp
roller or beam possesses as little weight as possible and is absolutely rigid whilst its
price is such as to enable a really practical use of the same.
In the drawing left with our Provisional Specification
Figure 1 shows a longitudinal section of the extremity of a warp roller or beam
constructed according to our invention.
Figure 2 represents a transverse section on the line 1-2 of Figure 1.
In the drawing accompanying our present Specification
Figures 3 and 4 represent in end elevation and longitudinal section respectively
a modification of our improved warp roller or beam.
Referring to Figures 1 and 2 our improved roller comprises four essential
parts, viz. —the disc A; the pulley B; the cylinder C; and the rod or shaft D
These four parts being made separately and connected as hereinafter set forth.
The disc A is made of chased sheet steel or other very rigid metal; it is provided
at its centre with a round hole having the same diameter as the cylinder C.

page_text: The pulley B consists of cast iron and is on the one hand attached to the said
disc by bolts E, and on the other hand to the said cylinder by screws F. By
fastening the aforesaid parts together in this manner absolute rigidity of the
whole device is ensured, other equivalent means can however be employed for the
same purpose.
The pulley B is provided with a central opening which is somewhat larger than
the exact diameter of the cylinder, and can therefore be easily slid upon the latter
to place it in the desired position; this having been effected the space
between
it and the outer periphery of the cylinder is filled up with a very fusible metal so
as to ensure its absolute adherence. This metal is indicated in the drawing by
crossed section-lining.
The cylinder C is made of sheet metal the thickness of which can be varied
according to the strength desired. This cylinder has a longitudinal groove
designed to receive the rod for winding up the threads.
At each end of this
cylinder we provide interiorly a reinforce H of cast iron which is firmly attached
to the cylinder without further boring and fastening. A hole is left at the centre of
this reinforce for the passage of the rod or shaft D or for fixing therein by means
of simple screw threads, or a simple journal or spindle.
The rod or shaft D of iron is hollow, and at its two extremities are provided two
solid journals L.
As above stated this rod or shaft can be replaced by screw-threaded spindles
fixed in the two ends of the cylinder.
A pressing-screw K can be provided for keeping the cylinder in its place upon
the rod or shaft.
The warp rollers or beams are made to correspond to a given maximum breadth
of surface for the threads. This breadth can be reduced at will for the same roller
or beam by simply moving the discs A a greater or smaller distance away from the
pulleys B, the latter remaining stationary. This adjustment can be obtained by
means of bolts E having two nuts, the lengths of which can be varied according to
the distance which the said parts are to be separated.
In the modification of our invention shown in Figures 3 and 4 the improved warp
roller or beam comprises an iron tube D to the ends of which are soldered points or
stem D' of iron.
This tube is surrounded by a covering o of wood or any other material, of the
length and diameter to be given to the roller; this covering is secured to the tube
by means of screws and is provided with a longitudinal groove for the thread rod.
A bush M is fixed at each end of the roller, which bushes fill up the space
which is left between the points or stem the wooden covering O; the said bushes
are provided at the part which touches the wood of the covering with a journal
intended to receive the pulley.
The bushes M are formed with an internal diameter slightly greater than that of
the stem D, and the remaining space is filled as at G by running in a very fusable
metal thus fixing the said bushes without further labor or adjustment.
The cast iron pulley B is arranged upon the said bush, the set-screw l'acts to
prevent it from coming off the journal and admits of the pulley being disengaged
and engaged at will.
The metal disc A which is made either of cast iron, or stamped sheet steel or of
any other metal affording the required stiffness is provided with a central hole of
the same diameter as the cylinder upon which it is placed. This disc is capable
of adjustment upon the roller O always being plumb and square to the rest of the
said roller. This is effected by means of four guide-rods S secured to this disc by
means of screw nuts. The said guide rods pass through the pulley which is always
fixed longitudinally and the disc A. can be fixed at any desired distance from the
pulley tightening the set-screw T.
This arrangement affords the advantage that the pulley B being movable at will
is capable of being removed and changed at will and the disc A also movable at
will, is very easily regulated by the guide rods S, and can be if necessary also

page_text: disengaged when the pulley B is removed. The roller can thus be dismounted with
the utmost facility in its three principal parts.
The cylinder by the uniformity of its parts, its absolute rigidity, and the perfect.
adherence of the bush M to the tube D (by means of our special method of running
in the metal G) forms a whole so rigid that no separation is to be feared.
The two other parts, the pulley and the disc which may be susceptible of wear
or accidents can be removed and replaced with the greatest facility.
In our mode of constructing warp rollers or beams the adjusting or fastening
parts are dispensed with, and it ensures, besides great lightness, perfect rigidity and
a very small cost.
It will be understood that the form and dimensions of the several parts of our
improved warp roller or beam can be varied without departing from the nature of
our invention.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what we
claim is :-
First. In the improved metal warp roller or beam substantially as above described
and illustrated in Figures 1 and 2 of the drawing the arrangement and construction
of the various parts and the method of uniting the same.
Second. The improved metal warp roller or beam substantially as above described
and illustrated in Figures 3 and 4 of the drawing.
Third. In a metal warp roller or beam the uniting of the parts thereof by the
direct use of molten metal, thus doing away with all adjustment, substantially as
above described and for the purpose specified.
