Improvements in Machinery or Apparatus for Holding Pile Fabrics
During the Beating or Pile Raising Process.
I, CHRISTOPHER LONGBOTTOM, of 27 Kirkgate, Bradford in the County of York,
Estate Agent do hereby declare the nature of this invention to be as follows:-
-
This invention relates to machines or apparatus for holding pile fabrics whilst they
are beaten to finish or raise the pile, and its object is to increase and prolong the
vibration occasioned by such beating and thereby facilitate the process.
To break the rigid connection with the tentering or beating machine the tenter
hooks supporting the fabrics are commonly connected to webbing attached to the
machine. My improvements consist in employing metallic springs instead of the
above mentioned webbing, which are more durable and materially increase and
prolong the vibration of the fabrics supported thereby. The said springs are preferably
formed and attached in the manner hereinafter described.
To carry out my invention I form the said tenter hooks at or attach them to the
ends of spiral springs having eyes at the other ends adapted them to be secured to
the tentering or beating machine. Two of such springs and hooks are preferably
made of one piece of wire, thus only one eye formed in the middle of said wire is
required for their attachment.
Instead of the said spiral springs I may use other forms of springs, as for instance:
flat and waved or corrugated springs. The said flat springs are preferably made by
flattening an extension of the wire forming the hooks, but the hooks may be attached
or attached to one
to such springs and two or more books may be formed on
As a modification the said tenter hooks may be formed in rows, and such rows
of hooks connected to the machine by spring attachments.

During the Beating or Pile Raising Process.
I, CHRISTOPHER LONGBOTTOM, of 27, Kirkgate Bradford in the County of York,
Estate Agent, 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 that class of machinery or tentering
apparatus employed to hold pile fabrics by their selvedges during the batting process.
that is whilst they are beaten to finish and raise the pile, and its object is to increase
and prolong the vibration occasioned by such beating and thereby facilitate the
process.
It is found that when the fabrics are supported by rigid hooks it is difficult to
sufficiently vibrate or shake such fabrics especially the edges by batting and attempts
have been made to overcome this by attaching webbing to the sides of the apparatus
to hold the said hooks and thus break their rigid attachment.
My improvements consist in employing metallic springs instead of the above men-
tioned webbing, which are more durable and consequently increase and prolong the
vibration especially near the selvedges of the fabric supported thereby.
I may employ spiral springs, or straight springs of any suitable section or waved or
corrugated springs preferably made of tempered steel and the hooks and means of
attachment to the apparatus may be formed of the same piece of metal as the spring
or be suitably attached thereto.
In order to fully describe my invention reference is to be had to the accompanying
drawing forming a part of this specification in which similar letters of reference
indicate corresponding parts in each of the figures.
Figures 1 and 2, represent two longitudinal views at right angles to each other
of a single hook with a spiral spring shank, attached to a portion of the woodwork 2
which is adapted to be fixed to the bars of the tentering apparatus, such woodwork
being shown in section in figure 2.
The hook A for supporting the fabric is formed at the free end of the spiral
spring B, the opposite end C of which is continued in the form of a spike D bent at
right angles to Cand adapted to be driven into the woodwork E.
driven over C into E as an additional means of securing it. The spring B may be
A staple F is 3
made waved or serpentine instead of spiral.
•
Figures 3 and 4 represent similar views of a pair of straight spring hooks, in which
the hooks A are formed at the ends of straight springs B connected together at their
point of attachment by the crown or continuous piece H and secured to E by the 3
staples F. Single springs hooks may be formed in this manner and attached in a
similar way to that represented in figures 1 and 2. And I may flatten the springs B
in order to make them more pliable or elastic.

page_text: Figure 5 is a similar view to figure 3, illustrating a modified method of attachment.
In this case eyes J are formed at the fixed end of each spring by coiling the wire, and
screws are passed through such eyes to secure them to the apparatus.
Figures 6 and 7 are also two longitudinal views at right angles to each other of
a hook fixed to the end of a flat inetallic spring B having eyes or holes J at its
opposite end adapting it to be secured by nails or screws to the tentering apparatus.
The spring may be corrugated transversely to increase its elasticity.
The woodwork E is fixed to the metal bars of the tentering apparatus in a convenient
manner or the spring hooks may be directly attached to such bars. Such spring
hooks may be fixed to bars of convenient length thereby forming them in rows to
facilitate their attachment to the tentering machine.
Having now particularly described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed I declare what I
claim is :-
The use of metallic spring tension hooks for holding pile fabrics on the tentering
machine during the batting or beating process, substantially as herein shown and
described and for the purpose specified.
