Improvements in Tension Apparatus for Beams for Lace and other
Machines.
I ARTHUR WILLIAM SMITH of 3 Ivenhoe Villas, Sherwood Rise, Nottingham, Lace
Manufacturer, do hereby declare the nature of this invention to be as follows:-
--
This invention relates to apparatus for regulating the tension on beams containing
yarn or other material in lace or other machines and it has for its object the improved
construction and arrangement of such apparatus whereby the tension can be
more conveniently and accurately adjusted than by the present system of cords springs
and weights.
In carrying out this invention a clip is formed by bending a strip of metal of
suitable dimensions into the form of a circle to fit the beam collar with an extension
or loop opposite the two free ends, the two ends are turned parallel to each other, and
are provided with holes through which is passed a screw bolt having a winged or
other suitable nut and to prevent the clip from cutting the beam collar and to insure
a regular amount of friction, the clip is lined with leather, india-rubber or other
suitable material.
The clip is placed on the beam collar with the loop or extension over a pin, secured
to the beam bearing and the requisite amount of tension is obtained by the clip by
means of the screwed bolt passing through the free ends.

Improvements in Tension Apparatus for Beams for Lace and other
Machines.
I, ARTHUR WILLIAM SMITH of Ivanhoe Villas, Sherwood Rise, Nottingham, Lace
Manufacturer, 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 apparatus for regulating the tension on beams containing
yarn or other material in lace or other machines and it has for its object the improved
construction and arrangement of such apparatus whereby the tension can be more
conveniently and accurately adjusted than by the present system of cords, springs and
weights.
The invention will be best understood by reference to the accompanying sheet of
drawings in which Figs. 1 and 2 are elevation and plan of the apparatus, Figs. 3 and 4
are elevation and plan of a modification thereof, Fig. 5 is a side elevation and fig. 6
is a front elevation showing the apparatus in position on the beam collar.
In carrying out this invention a clip A is formed by bending a strip of metal of
suitable dimensions into the form of a circle to fit the bean collar with an extension
or loop C on the opposite side of the beam to the two free ends D which are parallel
to each other and are provided with holes through which is passed a screw bolt E
having a winged or other suitable nut F. To prevent the clip from cutting the beam
collar and to insure a regular amount of friction it is lined with leather indiarubber
or other suitable material G secured in any well known manner or if preferred the
material may be secured round those portions of the clip where it is required.
The clip A may also be made in two portions see figure 3, and the two halves
secured together by a screwed bolt H₁ passing through the two ends H a block
preferably of indiarubber I being placed between them.
The clip A is placed on the beam collar J of the beam J' with the loop or
extension Cover a pin K secured to the beam arm L and the requisite amount of
tension is obtained by tightening the clip A on the beam collar J by means of the
screwed bolt E or other convenient method.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. The method of applying tension to the beams of lace and other similar machines
by means of a clip such as A operating substantially as and for the purpose described
and illustrated in the accompanying drawings.
2. In a lace or similar machine the employment of a clip such as A having an
extension or loop C or H a lining G and operated by a bolt E substantially as and
for the purpose described and illustrated in the accompanying drawings.
Dated this 9th day of November 1887.
ARTHUR WILLIAM SMITH.
