We FRANK LEEMING Machine Maker and ROBERT WILKINSON Overlooker both
of North Vale Works Bradford in the county of York, do hereby declare the nature
of the said invention for "IMPROVEMENTS IN APPARATUS FOR LETTING OFF THE WARP
IN LOOMS FOR WEAVING to be as follows:-
"
This invention relates to an improved combination of mechanism for automatically
adjusting and regulating the drag on and delivery of warp from the warp beam.
In the construction of apparatus for purpose aforesaid according to this our inven-
tion we employ on the axis or ruffle of the beam a worm wheel gearing with a worm
on a long collar free to slide or rise and fall on a vertical shaft-the head of the said
collar forms a hand wheel whilst its foot or lower end forms a flange having a
V shaped ring on its under face beneath which and also on and fast to the vertical
shaft, is a boss in the face of which is a V shaped recessed ring on the lower part of
the boss is a catch wheel operated by means of connecting rod and catch, from the
slay sword-To the upper part of the long collar, and under the hand wheel, is a clipor
forked end of a lever, on other end of which is a weight. The action is as follows-
Should the drag on the warp become greater than the resistance of the weight on
the lever, the teeth of the worm wheel will press on the thread of the worm, forcing
down the latter and the long collar, of which the worm is part, wherein the he and
she" rings will be forced together and the lower V disc being fast on the vertical
shaft will impart rotation to the worm which in turn will impart motion to the worm
wheel, and to the beam, until a sufficient length of warp shall have been given off,
whereon the weight will again by its forked lever, lift the long collar, and separate
the V, suspending rotation of the worm, until by strain on the warp, the V are
again forced together.
The hand wheel on the head of the long collar forms a ready appliance for turning
back the beam by the attendant when from any cause necessary.

We, FRANK LEEMING, Machine Maker, and ROBERT WILKINSON, Overlooker, both
of North Vale Works, Bradford, in the County of York, 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 an improved combination of mechanism for automatically
adjusting and regulating the drag on and delivery of warp from the warp beam.
In the construction of apparatus for purpose aforesaid according to this our inven-
tion, we employ on the axis or ruffle of the beam, a worm wheel gearing with a worm
on a long collar, free to slide or rise and fall on a vertical shaft, the head of the said
collar forms a hand wheel, whilst its foot or lower end forms a flange having a
V shaped ring on its under face, beneath which and also on and fast to the vertical
shaft, is a boss in the face of which is a V shaped recessed ring, on the lower part of
the boss is a catch wheel operated by means of connecting rod and catch, from tho
slay sword. To the upper part of the long collar and under the hand wheel is a clip
or forked end of a lever, on other end of which is a weight. The action is as
follows:-
Should the drag on the warp bocomo greater than the resistance of the weight on
the lever, the teeth of the worm wheel will press on the thread of the worm, forcing
down the latter, and the long collar of which the worm is part, whereon the "he and
she" V rings will be forced together, and the lower V's disc being fast on the vertical
shaft will impart rotation to the worm, which in turn will impart motion to the worm
wheel and to the beam, until a sufficient length of warp shall have been given off
whereon the weight will again by its forked lever, lift the long collar and separate
the V's, suspending rotation of the worm until by strain on the warp the V's are
again forced together.
The hand wheel on the head of the long coller forms a ready appliance for
turning back the beam, by the attendant, when from any cause necessary.
Such being the nature and object of this our said invention, the following is a
complete description of same, reference being had to the accompanying drawings:
Fig. 1 is an end elevation of beam and appliances connected therewith, the front
side frame being omitted so as to clearly shew the improved appliances. Fig. 2 is a
front elevation of Fig. 1.
At 1 is a worm wheel, as ordinary fixed on the end of the beam 2, the wheel 1
gears with the worm 3.which is cast to or forms part of the long collar 4 which is
free to slide or rise and fall on the vertical shaft 5 and having a collar forming a hand
wheel 6, its foot or lower part has a V or corrugated enlargement 7 corresponding
to a like surface formed on the boss 8 of the catch wheel 9 on the shaft 5, which
hoss 8 and wheel 9 are operated by means of a connecting rod and catch 10, receiving
motion from the slay sword 11 under the hard wheel 6 is a lever 12, and anti-

page_text: friction pulley 13 there being a counterbalanced lever 14 on the other end of the said
lever 12. The action is as follows:-
:―
Should the drag on the warp 2 become greater than the resistance of the weight 14
on the lever 12, the teeth of the worm wheel 1 will press on the thread of the
worm 3, forcing down the latter, and the long collar 5, of which the worm is part,
whereon the parts 7 and 8 are forced together, that is to say the part 7 is forced down
on the boss 8 and as the latter is through the action of the slay sword 11 and catch 10,
rotated, the worm 3 will be driven which in turn will impart motion to the worm
wheel i, and to the beam, moving the latter until a sufficient length of warp shall
have been given off, whereon the weight 13 will again by its lever 12, lift the long
collar 4 and separate the parts 7 and 8, suspending rotation of the worm,
until by
strain on the warp, the parts 7 and 8 are again forced together.
The hand wheel 6 on the head of the long collar 4, forms a ready appliance for
turning back the beam, by the attendant when from any cause necessary.
The construction of apparatus as above, obviates necessity of use of any vibrating
back bearers or vibrating rollers for the warp from the beam.
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:-
The construction, arrangement, and combination of parts constituting the improved
apparatus for purpose and as set forth and illustrated by annexed drawings.
