COMPLETE SPECIFICATION.
Improvements in Clips or Holders for Stretching, Finishing, or
Tentering Machines.
I, ALFRED AUSTIN WHITLEY of Park View, Walmersley Road, Bury in the
County of Lancaster, 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:-
My invention relates to clips or holders for stretching finishing or tentering
machines such as are described in the Specification of Letters Patent No. 2529
of 17th February 1890 granted to me and has for its object to improve the said
clips or holders and render them more efficient in action and convenient in use.
I will describe my invention with reference to the accompanying drawings
Figure 1 being a side elevation of a clip or holder mounted on one of the links
similarly provided, which, when connected together, constitute the series of clips,
or holders, for the said machines, the parts being in the position they assume when
the finger rests on the fabric. Figure 2 is an elevation at right angles to Figure 1.
Figure 3 is a view similar to Figure 2 but with the upper jaw and its axis and lever
removed. Figure 4 is a view like Figure 1 but with the parts in the position they
assume when the finger is not supported by the fabric. Figure 5 is a plan.
In the said clips or holders each link A has cast or secured to it a bed a for the
fabric and arms a for the axis a³ to which the upper jaw B is centered by the
ears b.
In the clip to which my invention is shewn applied a lever b₁ extends
from the upper jaw B and rests on the upper end of the finger C, (centered at c)
whose lower end crests on the fabric and is thereby retained in position (from
descending through the crifice a' beneath it) to keep the upper jaw B, out of
contact with the fabric the said arrangement having the effect of reducing the

pressure by the use of a lighter finger C, and to make the clip more positive in its
action I mount an anti-friction roller on the lever 62 or on the end of the
finger C, or on both, at the place where they bear on each other when the finger is
supported by the fabric.
In the form of clip described in my said former Specification where the centre
on which the finger turns is at a higher level than the ceutre on which the upper
jaw turns the roller or rollers will be applied either to the end of the finger
marked L in my former Specification or to the tongue of the upper jaw which
tongue is marked K in my former Specification or to both. An antifriction roller c³
may also be mounted in the finger C, at the lower part thereof so that this roller c³
bears on the fabric.
In order to enable the lifting of the finger to be effected more readily I make on
the aforesaid lever 6 which extends from the upper jaw B, or on the upper jaw B,
itself, a projection 6 which may be shaped like a spur tooth the corresponding
part of the finger C being similarly formed so that the parts act like the teeth of
the engaging spur wheels & the finger is lifted by raising the said lever.

A snug
may also be provided on the finger C to obstruct the lever 62 of the
upper jaw B & so prevent the said jaw B from being pulled over the front edge of
the lin

page_text: Having now particularly described & ascertained the nature of my said inven-
tion & in what manner the same is to be performed I declare that what I
claim is :-
1. In clips or holders of the kind hereinbefore described the employment of an
antifriction roller or antifriction rollers to take the bearing between the lever or
tongue extending from the upper jaw & the end of the finger whose lower part
rests on the fabric substantially as herein before described.
2. In clips or holders of the kind hereinbefore described the employment with
the finger supported by the fabric of a roller to bear on the fabric substantially as
hereinbefore described.
3. In clips or holders of the kind hereinbefore described the combination with
the upper jaw or the lever extending therefrom of a projection to bear on a corre-
sponding part of the finger which bears on the fabric substantially as & for the
purpose herein before described.
4. In clips or holders of the kind herein before described the provision of a snug
or snugs on the finger which bears on the fabric substantially as & for the purpose
herein before described.
5. The arrangement & combination of parts constituting a clip or holder for
stretching, finishing, or tentering machines substantially as hereinbefore described
& illustrated in the accompanying drawings.
Dated this 25th day of July 1895.
