Improvements in Warp Beam Tension Apparatus for Looms.
I, JAMES TAYLOR, of 85, Bolton Road, Chorley, in the County of Lancaster,
Overlooker, do hereby declare the nature of this invention to be as follows:-
:-
This invention relates to improvements in warp beam tension apparatus. In
lieu of the ordinary weight ropes coiled around the beam necks or buches I employ
an upper and a lower friction clip or brake block the projecting rear part of the
clips in the form of lugs-hooking into a vertical slot in a bracket fastened to
the framing of the loom and being drawn towards each other by means of an
adjustable screw bolt. The projecting front ends of the clips are drawn towards
each other by another adjustable screw bolt and interposed between the said front
ends are (preferably. three) helical springs one of which encloses the centrally
arranged adjustable screw bolt and the two others-one on each side of the
bolt encircle guide pillars or rods one end of which is fastened to one of the clips
while the other end passes through a suitable opening in the other clip. The two
screw bolts are preferably provided with wing nuts and the inner faces of the
friction clips may be lined with leather wood or other suitable material.
The above described arrangement of apparatus affords a ready means of
adjusting the pressure or friction upon the warp beam and therefore of regulating
or varying the tension of the warp threads.

Warp Deam Tension Apparatus for 10
1, JAMES TAYLOR, of 85, Bolton Road, Chorley, in the County of Lancaster,
Overlooker, 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 improvements in warp beam tension apparatus. In
lieu of the ordinary weight ropes coiled around the beam necks or buches I employ
an upper and a lower friction clip or brake block the projecting rear part of the
clips in the form of lugs-hooking into a vertical slot in a bracket fastened to
the framing of the loom and being drawn towards each other by means of an
adjustable screw bolt. The projecting front ends of the clips are drawn towards

the clips while the other end passes through a suitable opening in the other
clip. The two screw bolts are preferably provided with wing nuts and the
inner faces of the friction clips may be lined with leather wood or other suitable
material.
The above described arrangement of apparatus affords a ready means of
adjusting the pressure or friction upon the warp beam and therefore of regulating
or varying the tension of the warp threads.
In the accompanying drawings.

Fig. 3 a plan view shewing the method of applying my invention to a warp beam
neck or "ruffle" of the kind at present in ordinary use on warp beams having
weighted tension ropes.
Fig. 4 shews in end elevation my improvements as applied to the two ends of a
warp beam and
"
Fig. 5 is a cross sectional view of a yielding "back rest over which the warp
threads pass from the beam below the said yielding rest accommodating itself to
the varying pressure of the warp threads during the opening and closing of
the shed.
In the said drawings a is the warp beam 6 the ruffle or beam neck the upper
and the lower friction clips or brake blocks having a lining d-preferably of
leather fastened to the inner faces of the clips by means of countersunk screws.
The projecting rear part e of the clip c hooks into a slot in a screw bolt fastened
by means of the adjustable screw nuts gg to the bracket h―which is secured to
the side framing of the loom--and the said nuts at the same time enclose and hold
in position the lower projecting rear part of the clip c. is a screw bolt which
draws together the projecting front ends jj of the clips c c by means of the
regulating wing nut k and the spiral cushioning springs are preferably interposed
between the metal plate m and the projecting end of the clip c the said springs
being held in place by the pillars n n which at their lower ends are fast to the
clip c their upper ends sliding freely through suitable holes in the plate m. By
this arrangement I am enabled to employ springs of greater length than if they
were placed between the upper and lower clips c c¹ as described in my Provisional
Specification. From the plate m I prefer to project an index finger such as o
through a slotted index plate such as p whereby the amount of pressure on the
ruffle may be indicated or adjusted or re-set.
p is the yielding back rest-shewn in section at Fig. 5-carried on pivoted end
bearings in recessed brackets r r fastened to the framings of the loom. The
back rest p near each of its ends carries a bent arm t to the free end of which is
attached one end of a spring u whose other end is fastened to a finger v projecting
from the loom framing s. By this arrangement when the pressure of the warp is
increased on the upper face of the back rest p the said back rest is pulled down-
or round on its pivots against the pull of the spring u and when the pressure of
the warp is decreased the pull of the spring fetches the back rest back to its
former position this to and fro movement of the back rest being designed to
correspond to the similar give and take effect which obtains in rope-weighted warp
beam tension mechanism.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The improved warp beam tension apparatus consisting in combination with a
beam neck or ruffle of a pair of clips or brake blocks drawn towards each other by
screw bolts with means for regulating the pressure or friction of the clips or
brake blocks on the said ruffle and with cushioning springs the said parts being

drawings.
