Improvements in the Construction of Warp Beams for Weaving.
We, THOMAS BURNS, of 33 Freds Place, Sticker Lane, Weaving Overlooker, and
FREDERICK THOMAS SCHMIDT of No. 1. Hustlergate, Electrician, both of Bradford in the
County of York, do hereby declare the nature of this invention to be as follows:-
The object of our invention is to mount the flanges for retaining, the warp threads
on the warp beam in such a manner, that the same are true with the cylindrical or
body portion of the beam, and thereby to reduce the liability of the warp threads near
the flanges "sinking" below the circumference of the warp away from the flanges;
and thus to obtain more perfect and straighter selvages with less labour on the part of
the attendant; and to so connect the flanges that they may be moved with greater
facility and still retain the necessary truth in relation to the beam without the
customary packing, than is the case when they are secured in the usual manner.
We accomplish our object in the following manner - -Each bean is turned truly
cylindrical, with the spindles at the ends thereof, to the size of the hole in the centre
of the flanges, and in each beam we cut grooves in a longitudinal direction for the
reception of lugs in the centre hole of each of the said flanges. Through these lugs,
we pass rods screwed with right and left hand threads, the right hand threads passing
through the the lugs of one flange and the left through the other. The screwed rods
are all geared together at one end by spur wheels mounted on the respective rods and
on the beam spindle, so that by turning one of the wheels, all the rods and both
flanges thereon are moved simultaneously, the flanges moving true on the beam
towards or away from each other according to the direction in which the screws are
turned.

Improvements in the Construction of Warp Beams for Weaving.
We THOMAS BURNS, of Usher Street, Bradford, in the County of York, Overlooker,
and FREDERICK THOMAS SCHMIDT, of Hustler Gate, Bradford, aforesaid, 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 novel and useful improvements in the warp beams
employed in looms for weaving; and its object is to enable the flanges regulating the
width of the warp on such beam to be simultaneously adjusted.
For this purpose the said flanges are connected by rods which are respectively cut
with right and left hand screw threads adapted to engage with corresponding female
threads cut in or attached to such flanges. The said rods are suitably connected by
gearing which enable them to be simultaneously operated, thereby equally adjusting
both the flanges along the beam.
In order that those skilled in the art to which our invention appertains may under-
stand how to make and use the same, reference is to be had to the accompanying
drawing forming part of this specification in which similar letters of reference indicate
corresponding parts in all the figures.
Figure 1, is a longitudinal elevation of a warp beam fitted with our improvements.
Figure 2, is a transverse section of the beam, the broken line 1, 2, in the former
figure indicates the line of section. Figure 3 is an end view of the said beam, the cap
enclosing the gearing being omitted to insure greater perspicuity.
The flanges A are connected together by the rods B, which are respectively cut with
left and right screw threads to fit the female threads cut in the lugs C secured to and
projecting from the inside of the boss of each of the flanges A. Longitudinal grooves
are cut in the periphery of the beam for the reception of the rods B, and one end of the
rods pass through a plate D secured to the end of the beam I, where they are geared
together by the pinions E, fitted on the ends of such rods, engaging with a spur
wheel F mounted on the arbor G of the beam. The spur wheel F is provided with a
square boss H, adapted to receive a key or winch handle by which means it may be
rotated, thus actuating the pinions E and the rods B engaging the lugs C, thereby
simultaneously adjusting or moving the flanges A along the beam away from or
towards each other according to the direction the wheel Fis rotated. The collars I
secured on each of the rods A bear against the plate D and prevent the rods moving
longitudinally. A lock nut J is provided which screws on the end of the arbor (G
against the square boss H and prevents the position of the flanges being altered by the

page_text: vibration of the loom. A cap. K shown in section in Figure 1 is preferably fitted on
the end of the beam to protect the gearing.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed we declare what we claim is:
The combination with the warp beam of screw-rods connected to the flanges thereof,
operating to move the flanges towards or from each other when turned in one or the
other direction, and a spur wheel mounted loosly on the arbor of the beam provided
with a square boss, and adapted to engage with and simultaneously operate gear
wheels rigidly mounted on the end of the said screw rods, substantially as 'herein
shown and described and for the purpose specified.
