page_text: We, ROBERT HUNTER of 13 Beaconsfield Terrace, Hawick,. in the County of
Roxburgh, Factory Manager and THOMAS MCCREADIE of Wellington Street, Hawick,
aforesaid, Power Loom Tuner, do hereby declare the nature of this invention to be as
follows:-
This Invention relates to an improved picking motion for overpick power looms and
the apparatus constituting the invention consists of a lever attached at one end to the
sword of the loom and at its other end to a picking stick which passes down through
between the spindles whereon the picker is carried, the lower part of the stick being
connected behind the picker so as to drive it. To the ordinary picking shaft of the
loom there is attached a short iron or wooden rod the lower end of which is connected
to the picking stick either by an iron or wooden bar or by a leather or other strap or
its equivalent. Besides the lever connection before referred to the picking stick and
the sword of the loom are connected by a helical or other spring the action of which
is to bring the picker back again after each shot.
By this improved arrangement of apparatus the very objectionable twist that tho
present motion gives while picking and which is the cause of so many breakages in
straps, pickers and bolts is altogether avoided and the shuttle is thrown straight along
the reed thus saving much tear and wear in spindle ends and keepers, no picker bolts
are required and the picker being driven by direct contact with the stick right along
its guides wears much longer. The loom also runs much lighter and can be driven
faster than heretofore. As a proof of their running lighter looms fitted with this
motion gain on an average two picks per minute with the same drive.

page_text: We, ROBERT HUNTER of 13 Beaconsfield Terrace Hawick, in the County of
Roxburgh, Factory Manager, and THOMAS MCCREADIE of Wellington Street, Hawick,
aforesaid, Power Loom Tuner, 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 an improved picking motion for overpick power looms and
as represented in the accompanying drawings in front and end elevations at figures 1
and 2 and in plan at figure 3 the apparatus constituting the invention consists of a
lever arm A attached at one end to the sword B of the loom and at its other end to a
picking stick C which passes down through between the spindles D whereon the
picker E is carried the lower part of the stick being connected behind the picker so as
to drive it. To a lover F on the ordinary picking shaft G of the loom there is attached
a short iron or wooden rod H the end of which is connected to the picking stick
either by an iron or wooden bar or as indicated by a leather or other strap h or its
equivalent. Besides the lever connection before referred to the picking stick Cand
the sword B of the loom are connected by a helical or other spring I the action of
which is to bring the picker E back again after each shot.
By this improved arrangement of apparatus the very objectionable twist that the
ordinary motion gives while picking and which is the cause of so many breakages in
straps, pickers and bolts, is altogether avoided and the shuttle is thrown straight along
the reed, thus saving much tear and wear in spindle ends and keepers; no picker bolts
are required and the picker E being driven by direct contact with the stick C right
along its guides D wears much longer. The loom also runs much lighter and can be
driven faster than heretofore.
As a proof of their running lighter heavy picking looms fitted with this motion
gain on an average two picks per minute with the same drive.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
--
The combination of parts constituting the improved picking motion for overpick
power looms substantially as herein before described with reference to the accompanying
drawings.
