Tenter, JAMES EDGAR, 175 James Street, Bridgeton, Glasgow, Powerloom
Tenter, DAVID BOWMAN WRIGHT, 20 Nuneaton Street, Bridgeton, Glasgow,
Powerloom Tenter, do hereby declare the nature of this invention to be us
follows:-
The invention relates to improvements in swivel looms for producing loom-sewed
fabrics, having sprigs flowers or other patterns and consists of a frame, carried by
bolts in front of reed-cap of a powerloom.
This frame is capable of being moved in a vertical direction, by means of the
bolts working in vertical slots in the reed cap and, in addition, has the capability
of being moved in a horizontal direction, by means of the bolts working in horizontal
slots formed in the frame.
One or more shuttle-pointed "carriages" are provided and so adapted as to travel
in circular paths or races, formed in the frame. These carriages are actuated by
means of a horizontal rack and pinions the said pinions actuating the carriages by
means of spur gearing.
To admit of the use of a variety of colours, in swivelling, an ordinary change box
motion is used in combination with the "carriages." The "carriages" and gearing are
mounted on the aforementioned frame, and horizontal motion is communicated to
both the rack and frame from a convenient part of the loom by means of pivotted
arms levers and eccentrics or cams..

COMPLETE SPECIFICATION.
Improvements in Swivel Looms for Weaving.
We, ALEXANDER MATTHEW LYONS, of 54 Campbellfield Street, Glasgow,
Powerloom Tenter, JAMES EDGAR, of 175 James Street, Bridgeton, Glasgow,
Powerloom Tenter, and DAVID BOWMAN WRIGHT, of 20 Nuneaton Street,
Bridgeton, Glasgow, Powerloom Tenter, 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 swivel looms for weaving, to produce
loom-sewed fabrics, having sprigs, flowers or other patterns and consists of a frame
carried by bolts in front of the ordinary reed cap of a powerloom.
In carrying out our said invention as illustrated in part front elevation Figure 1,
in cross section Figure 2, and in detail views Figures 3 and 4, which are drawn to
a large scale, and in detail views, Figures 5, 6 and 7, we mount or bolt the frame A
to the front side of the reed cap B, of the powerloom, in such a manner that the
frame is capable of being moved in both the vertical and horizontal planes by
means of the bolts C working in vertical and horizontal slots c, said slots being
formed in the reed cap B (which is preferably provided with a metal plate B',) and
in the frame A. The said frame A is formed or provided with two, three or
more circular paths or races D, in which work two, three or more shuttle pointed
carriages E (shown more particularly in Figures 3 and 4) each of the said
carriages being provided with suitable means for carrying a bobbin or spool F.
D

page_text: In order to actuate the said carriages E, alternately to the right and left, we
provide a spur or toothed rack G, which derives a horizontal motion from any
convenient part of the loom by means of levers, arms, and eccentrics or cams.
The
said rack G works into corresponding toothed pinions H, one of which is mounted
within each path or race D, in such a manner as to actuate the carriage E either
to the right or left according to the movement of the rack G, through the medium
of the spur or toothed wheels J and pinions J¹, said pinions J¹ gearing with the
wheels or pinions J and also with the internal spur or toothed racks or wheels K
formed on or attached to each of the carriages E.
The frame A is, as well as the rack G, connected to any convenient part of the
loom, such as is shown in Figures 5, 6 and 7, that is to say, we provide the loom
with an auxiliary double crank shaft R, which is driven by the main shaft of the
loom by any suitable gearing; the cranks of the said shaft R are each connected
to the travelling catches or hooks P, Q, of the shedding mechanism, that is to
say, the jacquard or dobbic. The said hooks P¹, Q₁ are controlled by the
shedding mechanism and are caused to actuate their respective discs or spur
wheels P, Q at the proper time; the said motion of the discs P2, Q being
communicated to the frame A and the rack G by means of the levers P and Q,
which are connected to each other at p in such a manner as to enable them to be
actuated by the hook Q' through the medium of the small crank or disc Q³ and
rod Q, and at the same time in such a manner as to enable the rack G being
moved alone by means of the hook P which communicates its motion to the
lever P, through the medium of the small crank or disc P³ and rod P, the
end of which is connected to the lower end of the lever P while the lower
end of the lever Q is pivotted to any convenient part of the loom or floor.
The foregoing arrangement is such that when it is desired to put in a swivel
shot the Jacquard or Dobbie hook controlling the lever P is not raised and
therefore the hook P' engages with the spur wheel P and so actuates the rack G.
When it is desired to weave a detached or embosomed figure, the Jacquard
or Dobbie hook controlling the lever Q is not raised, and therefore the
hook engages with the spur wheel Q and so actuates the rack and frame
accordingly.
A continuous swivelled stripe or figure may be woven by swivelling alternately
with the ground, and detached figures may also be woven by controlling the action
of the hooks P, Q, by means of the jacquard or dobbie, according to the
requirements of the design.
When the operator desires to work near the reed or recds the frame A may be
lifted up vertically by means of the pivotted levers or handles L, one or more of
which may if desired be provided with a self-releasing catch (as shown in
Figure 2,) which depends therefrom and engages with the fixed piece of the
breast beam M. On the backward stroke of the lay N, the releasing catch /
travels clear of the fixed piece and the frame A is allowed to drop. The whole
arrangement thus forming an efficient working arrangement which may be attached
to any desired power loom so as to enable the loom to be capable of producing loom
fabrics, having sprigs, flowers or other patterns loom-sewed thereon."
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that we
claim is :-
1st. In swivel looms for weaving, the shuttle pointed carriages E, working in
circular paths or races D, formed on or attached to a moveable frame A mounted
in front of the reed cap of the loom, substantially as and for the purposes
herein before described and shown in the accompanying drawings.
2nd In swivel looms for weaving, the frame A and the means for enabling it to
be moved in the horizontal and vertical planes, substantially as and for the purposes
herein before described and shown in the accompanying drawings.
3rd The general arrangement, construction and combination of the various

page_text: parts constituting our improvements in swivel looms for weaving, all substantially
as, and for the purposes, hereinbefore described and shown in the accompanying
drawings.
Dated this 2nd day of June 1893.
