PROVISIONAL SPECIFICATION.
Improvement in Wire Weaving Power Looms.
Joseph TELFORD 23 Emmett Street Miles Platting Manchester, Engineer
and Machinist, do hereby declare the nature of this invention to be as follows:-
The improvement is on my first Patent (No. 14694) 18th September 1889 for
the bumping up of the weft wire. By one or two blows after each stroke of the
shuttle, the slay which carries the reed backwards & forward swings on a
centre shaft at bottom or at top of the loom-with levers joints and rods-and
rollers-adjusting screws weights and springs-operated on by cams running on
2nd motion shaft of the loom which holds the slay stationary until the shuttle pass
from side to side-instantly the shuttle has reached the opposite shuttle trap-
the cams let go the levers and carry the reed forward to face of woven web-
then it is brought back by the same cams-to allow the healds to cross, the same
cams let go the reed to bump the wire properly up.
Dated this 24th day of July 1894.
Improvement in Wire Weaving Power Looms.
I, JOSEPH TELFORD of 23 Emmett Street Miles Platting Manchester,
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 :-
The object of my invention is to make improvements in the working of wire
weaving power looms such as are described in my Patent No. 14694 of 1889.
By referring to the drawing sent herewith the nature of my improvements will be
readily seen. I bump up the weft wire with the slay after each stroke of the
shuttle. The slay (D) which carries the reed backwards and forwards swings on
centres (M) which may be at the bottom of the loom as indicated in the drawing,
or be above the loom as is desirable. The motions are got from the shafts
marked A. B & C. A. is the first motion shaft and gears into B which drives the
two cams (1), one at each side of the loom. These cams are on shaft (B) and are
driven in the direction indicated by the arrow, against the rollers (J) which are
fixed to the levers (L). The front springs (F) one on each side the loom give the
bumping blow whenever the rollers (J) drop into the two cut out portions of the
cams (1); and the levers (1), by means of the coupling rods (K) one on either
side of the loom, bring back the slay (D) when the rollers (J) are revolving
against the circular portions of the cams (I) thus extending the springs (F)
which when liberated, as previously described, give the blow. The cams (I) as
shown in the drawing give two blows of the slay after each stroke of the shuttle;
if one blow only is needed one of the cut out portions of each of the cams (1) is
filled in such a manner that the cams are made circular in outline in the filled
up
un portion.

page_text: 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 that what I
claim is :-
1st. The bumping up by power in the manner.described of the weft wires.
2nd. In wire weaving power looms the cams made to give either a single or
double blow as required.
