Improvements in Warping and Beaming Machines.
We, THOMAS BURGESS, LUKE HAROLD RENSHAW, and JOHN JOSEPH BURGESS,
trading as Renshaw, Burgess and Co., Washford Mill, Buglawton, Congleton, in
the County of Chester, Engineers and Machinists, do hereby declare the nature
of this invention to be as follows:-
This invention relates to a machine for preparing or beaming the warps for
smallware looms, in which ribbons, tapes, bands and other narrow articles are
woven.
At one end of the machine is fitted a creek to receive and hold the bobbins of
warp, yarn or thread and in front of this is placed a number of detector needles
for stopping the machine should an end fail.
The ends from the bobbins pass over guides and through the eyes of these
detector needles, so that the needles are suspended upon the thread, and should an
end break or fail the needle falls.
The warp beams or bobbins are rotated by a shaft or spindle driven by a friction
drum, the axle of the driven or driving drum being pivoted, so that one drum lies
and presses against the other, but is capable of being readily removed. Below
the two drums is placed a brake of wedge shape, which can enter between them,
and stop the driven one. The brake is pivoted upon or carried by a lever or levers,
one end of which extends below the detector needles. When the needle falls upon
the breakage or failure of the yarn, it comes in contact with the brake lever, or
with a wiper or other device connected thereto, and so over-balances the lever and
causes the brake to come into contact with the rotating drums, by which it is
drawn up between them and separates them, stopping the warp beam or bobbin.
A traverse for the bobbin spindle is actuated by a cam rotated either by a worm
and worm wheel or train of spur or other wheels.
A measuring roller and counting mechanism may be placed between the needles
and the warp bobbin for the threads to pass over.

Improvements in Warping and Beaming Machines.

Price 8d1

page_text: of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:
This invention relates to a machine for preparing or beaming the warps for
smallware looms, in which ribbons, tapes, bands, elastic web and other narrow
articles are woven.
In the warping of yarn for smallware weaving the warp, yarns are delivered in
the form of a tape or chain or bunch of yarn to the beams or bobbins and this
machine is designed to provide for the stoppage of the warp beam or bobbin on
the breakage or running off of any end of yarn.
It consists essentially of a machine constructed with a number of needles sus-
pended upon the warp yarns and connected by a pivoted lever with the driving
mechanism whereby the rotation of the warp beam or bobbin stopped when the
end of the yarn breaks or fails.
It will be fully described with reference to the accompanying drawings.

Fig. 2. Side elevation of the other part of the machine (a continuation of Fig. 1).

Fig. 4. Plan of the journal or pivots of the pivoted lever H Fig. 1.
Fig. 5. Plan of Fig. 2.
Fig. 6. Detail-end view of supporting bracket for the bobbin or beam
shaft.
Fig. 7. Perspective view of modified form of creel.
The creel A which may be of any ordinary construction is fitted at one end of
the machine to hold the bobbins B of warp yarn which are prevented from unwinding
too quickly by a spring bor other device fitted thereto. Or the creel may be made
in the form shown in Fig. 7 in which the weight of the bobbin set on an inclined
peg gives the desired amount of drag. In this modification the yarn pases from
the bobbins through combs or reeds A¹ placed on top of the creel.
In a suitable frame C in front of the creel A we mount or place a number of
detector needles D. (one for each thread of warp yarn or end E) with a hole or
eyed at the upper end through which the warp yarn E passes and upon which tho
needle D is suspended.
Each needle D is affixed to or carried by a pivoted lever F which when the needle
falls strikes or rests upon a transverse bar or rod G and depresses it. The bar or
rod G is connected by a connecting rod g with a nicely adjusted and pivoted lever H
which actuates a brake and the driving mechanism. The levers F are preferably
made of sheet metal to which the needles D are soldered and the ends are guided
by a reed K the dents k of which are prolonged upwards and their upper ends serve
as guides to deliver the threads E to the eyes of the detector needles D. K' are
rollers or glass or other rods over or under which the threads E pass as required.
The levers L and transverse connecting rod serve to lift or replace one or more
of the needles ]) or to lift them above the frame for the purpose of threading.
A double set of needles M set alternately and raised and lowered by a handle m
with eyes through which the yarns pass are employed to take the cross for twisting
in the warps.

The free end of the pivoted lever H is connected to the brake P, on the falling
of one of the needles the lever H is overbalanced and raises the free end to which
is pivoted the wedge f one side of which is then in the path of the rotating pin r
in the end of the driving drum R and the other side rests against the depending
arms or member of a pivoted bell crank or other lever f¹. Against this wedge f
when raised the rotating pin r on the end of the rotating driving drum R comes
in contact and raises the other arm or member of the lever f¹. The bell-crank
lever f¹ by means of a notch s holds the sliding bar S against the pull or pressure
of a spring s which draws or causes the bar to move when released by the lever fl
At the other end the sliding bar S operates a second bell crank lever S¹ pivoted
at s¹ the free end of the lever S₁ being connected to one end of a brake P surround-
ing a brake wheel p on the driving shaft R',

page_text: The bar S may also carry the strap fork R" so that the driving strap may be
thrown on to a loose pulley by the same operation that applies the brake.
The measuring roller N is mounted between the needles D and the warp beams
or bobbins W to which is connected a registering or indicating dial N¹ by a series
of worms and worm wheels n n'.
The bobbins or beams W are mounted on a spindle t driven by a drum T from
the drum R by the strap t¹. The yarn E passes through the guides U to the
bobbins or beams W and these guides are caused to traverse to and fro to distribute
the yarn on the warp bobbin in one direction by the cam u acting upon the pivoted
rods or levers U and in the other direction by the weight u¹ through the band or
rope
The strap on the cone drums R and T is moved to decrease the speed as the
bobbins or beams W fill by the pivoted lever V resting against the surface of the
beams or bobbin so that it takes up the warp at one uniform rate or speed from
beginning to end of the warp. The strap fork X is mounted on two rods & upon
which it is capable of sliding to and fro and is connected to a lever the upper
member of which is connected with the lower end of the lever V. The move-
ment of the upright lever V in either direction gives a corresponding horizontal
movement to the lever v¹ and causes the strap fork X to move upon the rods .
The bobbin or warp spindle is supported at its outer end by a bracket Y on a
stud Y¹ attached to the frame. The bracket is held in position by a spring y and
can be drawn forward and disengaged from the spindle for the purpose of removing
or replacing the bobbins or beams W.
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 :-
1. A machine for warping and beaming yarn, constructed with a number of
needles through the eyes of which the yarn passes and suspended by the yarn so
that when the end breaks or fails the machine is stopped, substantially as described.
2. In a machine for warping and beaming yarn the combination with the creel
at one end of the machine for holding the bobbins and with the mechanism for
driving the warping bobbins or beams at the other end of the machine, of the
detector needles suspended upon the thread and the pivoted lever with which they
engage to stop the machine when any yarn end breaks or fails, substantially as
described and shown.
3. A machine for warping and beaming yarn having the several parts con-
structed and arranged in combination, substantially as described and shown.
