SLIDING TUG STRAP HOLDERS FOR POWER LOOMS
Year: 1886

page_text: We, THOMAS KENDRAY, of Sarnia, in the County of Lambton, Province of
Ontario, Canada, Boss Weaver, and GEORGE N. MATHESON, of the same place, do
hereby declare the nature of our Invention for "SLIDING TUG STRAP HOLDERS
FOR POWER LOOMS," 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 an improved sliding holder, which connects the tug
strap to the picking stick, or picker staff of a Power Loom.
The method in common use for securing the tug strap to the picking stick, is by
the tug strap passing through a loop of leather, the two ends of this leather loop
are secured to the picking stick, by a common screw, and in one side of the picking
stick, a number of screw holes are formed, and the tug strap is adjusted, by
drawing the screw out of one hole, and driving it into another, higher or lower on
the picking stick as required.
The disadvantages of this construction are as follows;-viz:-by the drawing
of the screw out of one hole, and driving it into another, when wishing to change
the position of the tug strap on the picking stick, the holes become worn, and thus
become in a short time too large, to firmly hold the screw, and not only this, but
by driving the screw in and out of the picking stick, so often, and the screw holeš
being so close together, they weaken the picking stick, so that it checks or cracks,
and thus renders it useless, as the cracking of the stick enlarges the screw holes,.
so that the screws fall out, with the least movement of the picking stick, so that
there is a loss of time in renewing the picking stick, as the machinery has to be.
stopped, to do so, a loss of material, as the picking stick is rendered valueless, and
a loss of labor, as a new picking stick has to be manufactured. And not only
that, but another disadvantage is met in using the common tug strap holder,,
viz:-The leather loop being pliable, and only secured at the upper end to the
picking stick; as the latter moves forward, to impel the shuttle, the lower part of
the loop rises up, on the picking stick by the force of the picking stick moving
forward, and the jerk of the connecting rod, permitted by the looseness of the loop,
so that in the common style of a tug strap holder, an uneven motion is given to
the shuttle, and more motion sometimes given than is actually required, and the
picking stick is, jerked or jarred, so that in a short time it is useless. All of these.
disadvantages are completely overcome by using this improved sliding tug strap-
holder

page_text: This invention consists of a slide, provided with an eye; fitted to the latter, and
held therein is the tug strap,--the free ends of which are attached to a connecting
rod, this slide is provided with an elongated slot, through the latter, and the
picking stick a bolt passes, and a nut screwed on this bolt, binds them firmly
together; by unloosening this nut, the slide may be adjusted higher or lower on
the picking stick, and when at the required elevation, it is firmly held there, by
tightening the nut again.
The object of this invention is, to save time, and as a result of saving time, the
loom works more continuously, so that more work or yards is produced by each
loom; and labor and material are also saved by using this improved sliding tug
strap holder; a large percentage of all which, is lost by using the one in common
use, and this invention will not only effect this result, but will give a steady, even
motion to the picking stick and shuttle; and at the same time permit a fine
adjustment of the tug strap on the picking stick,..
The construction and operation will be more fully described and claimed, with
reference to the accompanying drawings wherein,
Fig. 1. is a perspective view of a picking stick, showing this improved sliding
tug strap holder.
Fig. 2. is a detail perspective view of the tug strap.
Fig. 3. is a side elevation of the sliding tug strap holder.
A, designates a slide; fitted to and held in an eye, A¹, in which is a tug strap, B,
the free ends of this tug strap are secured to the connecting rod, C.
This slide, A, is firmly secured to a picking stick, D, by a bolt, E, and nut, E¹,
or other suitable securing device, when a bolt and 'nut are used, the shank of the
bolt passes through an elongated slot, F, in the slide, A; the nut, E¹, projects
beyond the slot, and when tightened, binds the slide, A, on the picking stick, D.
By unloosening the nut, E¹, the slide, A, may be adjusted higher or lower on the
picking stick, D, to increase or diminish the force with which the shuttle is to be
impelled, through the shed of the warp, and when properly adjusted, the slide, A,
is firmly held at the required elevation, by tightening the nut, E¹, again.
The elongated slot, F, formed in the slide, A, permits it to be moved up and
down on the picking stick, D, without changing the position of the bolt, E, Bo that
one hole only is all that is required in the picking stick, D.
This construction gives a strong and durable picking stick, and firm holder for
the tug strap, which are seldom renewed, if at all, so that no time is lost, in
stopping the machinery to insert a new picking stick or holder, the loom thereby
works more continuously, so that more work or yards can be produced by each
loom, using this sliding tug strap holder, than by using the one in common use,
and no labor or material are used to make a new picking stick, or holder; so that
by using this improved tug strap holder, time, labor, and material are saved, and
more work or yards produced by each loom, which is a considerable monetary
saving in the running expenses of a Power Loom.
And also by having the tug strap, firmly secured in place, as shown in this
improved holder, an even, steady motion is insured to the picking stick and
shuttle.
And further, the sliding holder is capable of a very fine adjustment when
constructed in this manner.
There are several methods, which would suggest themselves to the skilled
mechanic, by which this sliding tug strap holder, could be secured to the picking
stick, and the tug strap to the sliding holder, than that herein before described, but
the best results obtained so far, have been procured from connecting them in the
manner hereinbefore described.
A slide constructed in the form of a box, and secured at any elevation on the
picking stick by a set screw, passing through one side of the box, and biting on
the picking stick, has not been found to produce as satisfactory results as the slide
herein before described.

page_text: Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1st A slide, to which the tug strap is secured, capable of sliding up and down on
the picking stick, and rigidly secured, thereto when required, for the purpose
specified.
2nd A sliding tug strap holder, A, formed with an eye, A', and secured to the
picking stick, D, by a bolt, E, and nut, E¹, or their equivalent, substantially as
shown and described and for the purpose set forth.
3rd A sliding tug strap holder, A, formed with an elongated slot, F, and eye, A',
secured to a picking stick, D, by a bolt, E, and nut, E¹, or other suitable securing
devices, substantially as shown and described and for the purpose specified.
