PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Indicating the Tension upon the
Warps of Looms for Weaving.
I, FREDERICK WILLIAM GELDER of 24 Elmfield Terrace, Saville Park,
Halifax in the County of York, Mill Manager, do hereby declare the nature of this
invention to be as follows
I employ a feeling arm or arms, pivotted in a suitable manner, and kept in
contact with or pressing against the warp, by weights, springs, or other means, one
end of such arm or arms being connected by wire rod or other means to a dial,
plate. or indicator, which as the tension upon the warp varies, indicates such
movement, or variation.
.
The connection between the feeling arm or arms, and the runner may be of any
form or inaterial so as to act upon the indicator.

Fig. 1. shows a side elevation of my apparatus applied to a room.
Fig. 2. is a plan of Fig. 1.
A. A, are the tension rods at the end of the feeling arm or shaft B, the said rods
are preferably both kept in contact with the warp or piece C, along its entire width,
by means of the weight D, upon the scaled rod E, upon which it may be adjusted,
to suit the quality of the piece being woven.
The feeling arm or shaft B is carried in suitable brackets F F, and terminates in
the rod or finger G, carrying the marker H, for indicating the variation of the
tension on the piece, upon the indicator sheet J, which is preferably endless upon
rollers K and L. The rod or finger G may be operated from the oscillations of the
beam or beams.
The roller K is driven by shaft N. bevel wheels O. P, cross shaft R, operated by
pinion wheel S, from the piece beam or other suitable part of the loom.
For adjusting the indicating sheet and its carriage M laterally; (so as to use up
the full width of the sheets by marking spirally upon such sheets), upon the cross

page_text: shaft R is a worm S, gearing with a worm wheel S', upon a screwed shaft T this
screwed shaft carries the carriage M of the indicating sheet J, or instead of the
screwed shaft, the worm may gear into a rack carrying the carriage M.
There is a hand wheel V upon the said cross shaft R, for lateral adjustment of
the indicator sheet by hand. A box W is placed at the bottom of the sheets with
rollers for their reception, as they are being marked. Ruled lines are preferably
provided upon the indicator sheet at intervals which more clearly show the deviations
(if any) of the finger lines.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I would have it understood
that I do not confine myself to the means shown or described for operating the
feeling arm and marking finger, or for revolving the indicating sheets, as it may be
done by various mechanical means, but I declare that what 1 claim is :-
1. The use and employment of a feeling arm or arms, or oscillating beam or
beams, pivotted and mechanically arranged so as to operate a rod, pencil or finger,
and mark the variations of the tension of the warp or piece upon an indicator or
chart for the purposes described.
2. The general arrangement and construction of apparatus, such as shown and
described, and for the purposes set forth.
