Improvements in Shuttle Check Motions and Spring or Elastic
Picker Buffers for Looms for Weaving.
I, THOMAS LONSDALE, of The Uplands, Holcrombe Brook, Tottington, near
Bury, in the County of Lancaster, Mill Furnisher, 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 shuttle check motions and spring or
elastic picker buffers for looms for weaving and has for its object to dispense with
check straps, check ends, buffer and buffer straps now in common use and provide
simpler and more durable means to check the shuttle and picker.
And in order that my invention may be more fully understood I have caused
to be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is a front view, Fig. 2 a plan of the portion of the shuttle box to
which my improvements are applied. Fig. 3 is a plan of a modification thereof.
In carrying out my invention and referring to the figures generally I employ,
in place of the check strap or end now in use, an arm or bracket a adapted to
project through or passing over the shuttle box back b, as shown in annexed
drawing, which arm or bracket a is adjustably secured to a spindle c arranged to
slide at the shuttle box back in a small bracket, step, or metal or leather
loop d. The spindle c is under the influence of a spiral spring e, which may be
an open one, see Fig. 2, and placed on the spindle c between its head c' and the
bracket, step or loop d, or it may be a closed spring, as shown in Fig. 3, attached
to the end of the spindle c and to the shuttle box back b, which springs serve to
check the shuttle when entering its box..
When using the shuttle check motion described, separately, the bracket, step, or
loop d is attached to the shuttle box back b, whilst when using it in connection
with the spring or elastic picker buffer, to be described, the bracket, step, or loop d
is secured to the arm of a bracket f' forming part of the picker buffer and
projecting through a slot in the shuttle box back b.
The bracket is under the influence of a closed spring attached to the arm ƒ
and to the shuttle box back bat b².
The inner end of the bracket f' is formed to project into the shuttle box and
has a hole i for the picker spindle k to pass through, as well as the arin or bracket a,
each being faced with leather l, the lower side fs of the bracket f' serving also as
a guide for the shuttle in lieu of the ordinary wooden guide now in use.
It will thus be understood that the shuttle check motion and spring or elastic
picker buffer described may be employed together or each independently of the
other.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim, is-
"In looms for weaving."
1st. A shuttle check motion, consisting of an arm or bracket a projecting through
or passing over the shuttle box back b and adjustably secured to a spindle c suitably
guided and under the influence of a spring e at the shuttle box back b, substantially
as and for the purpose set forth.
2nd. A spring or elastic picker buffer consisting of a bracket funder the
nfluence of a spring h and having an arm f projecting through a slot b¹ in the
huttle box back 6 and an end 2 through which passes the picker spindle k,

page_text: 3rd. A combined shuttle check motion-and spring or elastic picker buffer, con-
sisting of an arm or bracket a projecting through or passing over the shuttle box
back and adjustably secured to a spindle 'suitably guided and under the influence
of a spring e at the shuttle box back and of a bracket under the influence of a
spring and having an arm f projecting through a slot in the shuttle box back b
and an end through which passes the picker spindle k, substantially as and for
the purpose set forth.
