PROVISIONAL SPECIFICATION.
Improvements in Pattern Indicating Apparatus for Chenille Looms.
1, JOHN STEWART TEMPLETON, of the firm of James Templeton and Company,
of William Street, Glasgow, in the County of Lanark, North Britain, Carpet
Manufacturers, do hereby declare the nature of this invention to be as follows, that
is to say:
My said invention has for its objects to facilitate operations, to diminish liability
to make mistakes, and to save the expense of renewals of patterns, in weaving
particolored chenille.
In carrying out my invention, instead of as heretofore, cutting the patterned
design paper into strips, I fix the more or less complete pattern upon an endless
band distended upon a pair of horizontal rollers, one of which rollers is connected
by gearing with the take-up gearing of the loom. The connecting gearing is
arranged to be adjustable for reversing the pattern band for symmetrical patterns.
In front of the band there is a pointer on a rod adjustable by means of a screw
spindle across the face of the pattern. As the weaving proceeds the pattern band
moves under the pointer so as at every weft shot or pair of weft shots to show the
color of weft to be shot. When one vertical line of the pattern has been gone
over the pointer is by hand adjusted transversely to the next line.
Dated this Sixteenth day of December 1891.

COMPLETE SPECIFICATION.
Improvements in Pattern Indicating Apparatus for Chenille Looms.
1, JOHN STEWART TEMPLETON, of the firm of James Templeton and Company,
of William Street, Glasgow, in the County of Lanark, North Britain, Carpet
Manufacturers, 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, that is to say :-
My said invention has for its object to facilitate operations, to diminish liability
to make mistakes, and to save the expense of renewals of patterns, in weaving
particolored chenille; and for these purposes the loom is furnished with improved
apparatus for indicating successive positions on the pattern as the weaving
proceeds.
And in order that my said invention and the manner of performing the same may
be properly understood 1 hereunto append a sheet of explanatory drawings to be
hereinafter referred to and showing an example of my improvements.
Figure, 1, of the drawings is a front elevation and Figure, 2, is a side elevation of
my improved apparatus, together with as much of the loom as is needed to show
the positions of the parts. In these drawings the same reference letters are used
to mark the same or like parts wherever they are repeated.
In carrying out my invention, instead of as heretofore, cutting the patterned
design paper into strips, I fix the more or less complete pattern upon an endless
band, A, distended upon a pair of horizontal rollers, B, and, C, one, B, of which
rollers is supported above the other by a pair of standards, D, fixed to the cross
frame piece, E, of the loom, while the other roller, C, is held by brackets fixed. to
the same frame piece, E, and is connected by gearing with the take-up gearing of
the loom. This connecting gearing comprises a series of pinions, F, G, H, and, J,

page_text: one, F, of which gears with a pinion, K, forming a part of the take-up gearing of
the loom. The connecting gearing also comprises a pair of lantern or toothed
wheels, L, and, M, connected by a pitch chain, N, guided by pulleys, P, and, Q.
One, L, of the wheels, L, M, is fixed on the same shaft, R, as. the pinion, J, the
other, M, being keyed on a shaft, S, which carries one, C, of the two rollers
distending the endless band, A. The connecting gearing is arranged to be
adjustable for reversing the motion of the pattern band, A, for symmetrical
patterns. When it is desired to reverse the direction of the endless band, A, a
forked hand lever, T, centred on the shaft, R, and carrying in its lower ends
the pinions, F, G, and, H, is moved so as to put the pinion, F, out of gear from the
pinion, K, and to cause the pinion, H, to engage with the pinion, K. When the
pinion, F, gears with the pinion, K, as shown in Figure, 2, the motion it imparts is
reversed by the action of the intermediate pinion, G, so that when the lever, T,
is shifted to put the pinion, H, into gear instead of the pinion, F, the motion
imparted is in the opposite direction to what it was before.
In front of the endless band, A, there is a pointer, X, adjustable horizontally by
means of a screwed spindle, U, on the inner end of which it is fixed, this spindle, U,
being held in guides, V, fixed to the frame piece, E, and having on it an internally
screwed thumb nut, W, by turning which the spindle can be moved through the
guides, V. The pointer, X, is also adjustable vertically by means of a screwed
rod, Y, on which it is set.
As the weaving proceeds the pattern on the endless band, A, moves under the
pointer, X, so as at every weft shot or pair of weft shots to shew the color of
weft to be shot. When one vertical line of the pattern has been gone over, the
pointer, X, is by means of the screwed thumb nut, W, adjusted transversely to the
next line by hand.
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 :-
The improved pattern indicating apparatus for chenille looms, comprising in
combination, a distended endless band having the pattern fixed on it, gearing
'connecting the band to the take-up gearing of the loom, and a pointer held in
front of the band, and adjustable horizontally and vertically, the whole being
arranged and operating substantially as and for the purposes hereinbefore
described.
