PROVISIONAL SPECIFICATION left by the said Herbert Anderton Foster at
the Office of the Commissioners of Patents on the 5th April 1881.
HERBERT ANDERTON FOSTER, of Queensbury, in the County of York, Spinner
and Manufacturer. "IMPROVEMENTS IN LOOMS FOR WEAVING."
This Invention relates to the class of loom employed for weaving figures or
designs upon the surface of the "piece" or fabric after the manner of embroidering,
and the object of the Invention is, by the use and combination of appliances and
apparatus hereafter referred to, to facilitate the production of such figures, designs,
or pattern.
Ön swivel looms constructed according to this my Invention I employ on the
rack carrying the embroidering or figure shuttles projections or safety guards,
which when the rack is lowered will depress and level and so protect from injury
any ends or part of the warp improperly shedded or raised through defective action
of the jacquard or pattern mechanism.
The embroidering shuttles are constructed of an outer shell or casing having a
disc or circular spool, and provided with adjusting holes and spring tension device
for the embroidering thread.
For insuring the true position of and for effecting the necessary change of position
laterally of the rack and embroidering shuttles so as to distribute the figures or
patterns over the surface of the piece in predetermined order, I employ catch and
ratchet wheel motion controlled and operated from the jacquard or pattern
mechanism.
The raising and lowering the rack and embroidery shuttles is effected by means
of a cam operating levers and connecting rods, thereby imparting a partial turn
or rotation to a cross shaft carrying by arms said rack and embroidering shuttles.
The embroidering shuttles are worked by means of a scroll, operating levers, and
cords, which give the requisite to and fro motion to the said shuttles.

page_text: The picking motion for the ordinary shuttle is regulated and controlled from the
jacquard by means of levers and clutch box, so as to be out of action during the
time the embroidering shuttles are in operation.
The cam for raising and lowering the embroidering shuttles and rack, and the
scroll for operating the embroidering shuttles, are connected and secured to each
other so as at all times to act in unity, thereby to ensure the rack and embroidering
shuttles being lowered into proper position before the said shuttles can commence
picking. The cam and scroll receive motion from a clutch mechanism brought into
operation by means of levers, connections, and catches controlled by the jacquard
or pattern mechanism, the clutch action in connection with the picking motion
of the ordinary shuttle being likewise controlled by the same jacquard motion,
thus ensuring a correct timeing of the action of the ordinary shuttle and the
embroidering shuttles. The action for lowering the rack and embroidering shuttles
into position at the same time puts the picking motion of the ordinary shuttle out
of action.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Herbert Anderton Foster in the Great Seal Patent Office on the
4th October 1881.
HERBERT ANDERTON FOSTER, of Queensbury, in the County of York, Spinner
and Manufacturer. "IMPROVEMENTS IN LOOMS FOR WEAVING."
This Invention relates to the class of loom employed for weaving figures or
designs upon the surface of the "piece" or fabric after the manner of embroidering,
and the object of the Invention is, by the use and combination of appliances and
apparatus hereafter referred to, to facilitate the production of such figures, designs,
or patterns.
On swivel looms constructed according to this my said Invention I employ on
the rack carrying the embroidering or figure shuttles projections or safety guards,
which when the rack is lowered will depress and level and so protect from injury
any ends or part of the warp improperly shedded or raised through defective action
of the jacquard or pattern-mechanism.
The raising and lowering the rack and embroidering shuttles is effected by means
of a cam, operating levers, and connecting rods, thereby imparting a partial turn
or rotation to a cross shaft carrying by arms said rack and embroidering shuttles.
The embroidering shuttles are worked by means of a scroll, operating levers,
and cords, which give the requisite to and fro motion to the said shuttles.
The picking motion for the ordinary shuttle is regulated and controlled from the
jacquard by means of levers and clutch box, so as to be out of action during the
time the embroidering shuttles are in operation, and the cam for raising and
lowering the embroidering shuttles and rack, and the scroll for operating the
embroidering shuttles, are connected and secured to each other so as at all times

page_text: to act in unity, thereby to ensure the rack and embroidering shuttles being lowered
into proper position before the said shuttles can commence picking. The cam and
scroll receive motion from a clutch mechanism brought into operation by means of
levers, connections, and catches controlled by the jacquard or pattern mechanism.
The clutch action in connection with the picking motion of the ordinary shuttle
being likewise controlled by the same jacquard motion, thus ensuring a correct
timing of the action of the ordinary shuttle and the embroidering shuttles. The
action for lowering the rack and embroidering shuttles into position at the same
time puts the picking motion of the ordinary shuttle out of action.
Such being the nature and objects of this my said Invention, I will now proceed
to describe the same in detail, and in order that the Invention may be fully
understood, I have hereunto annexed 3 Sheets of Drawings illustrative thereof, and
have marked the same with Figures of reference.
understood, I have hereunto annexed 3 Sheets of Drawings illustrative thereof, and
have marked the same with Figures of reference.
DESCRIPTION OF THE DRAWINGS.
Figs. 1 and 2, Sheet 1, are end and front elevations of part of loom having my
improvements applied; Figs. 3 and 4, Sheet 2, are back and end elevations of
above on enlarged scale. The several views on Sheet 3 are details or parts
detached drawn about half full size.
Referring now to the application for levelling the warp, illustrated by Figs. 1 & 2,
Sheet 1, and by details at Figs. 3 and 4, Sheet 3, at 1 is the rack carrying the
embroidering shuttle 2. The rack 1 is provided with projecting safety guard 3,
which when the rack is lowered depresses or puts down any end or ends of warp
improperly shedded, or which should not have been raised, and so prevents injury
to the warp.
The raising and lowering the rack and embroidering shuttles is, by means of a
cam 4, operating levers 5 and 6, and connecting rod 7, thereby imparting a partial
turn or rotation to a cross shaft 8 carrying, by means of the arm 9, the rack 1 and
shuttles 2, full detail drawing are on Sheet 3, Fig. 3.
The embroidering shuttles 2 are worked by means of the scroll 10 operating the
lever 11 by means of the stud or pin 12, which is received within the groove of
the scroll 10. The lever 11 being operated in its turn by means of the cross
arms 13 and ends 14, 14, gives the requisite to and fro motion to the shuttles 2.
The bosses of cams 4 and scroll 10 fit into each other, and are secured by set
screw 4ª so as to ensure the cam and scroll acting together.
The picking motion for the ordinary shuttle and for the embroidering shuttles is
regulated and controlled from the jacquard by means of levers and clutch boxes,
so that the ordinary shuttle will be out of action during the time the embroidering
shuttles are in operation.
The cords 15, 15, from the jacquard are connected to the levers 16, 16, the links
17, 17, to the double lever 18, so ensuring the catch 19 being in connection with
lever 21 only when lever 20 is clear of catch 21, and visa versa; that is to say,
catches 19 and 20 cannot be engaged at one and the same time; 18ª is a spring
for holding lever 18 in position when set, so that when one of the levers 10 is
operated the other will be moved in the reverse direction, so placing one or other
of the vertical catches 19, 20, in position to engage with the rocking levers 21, 21ª,
operated by cams 22, 22ª, putting the clutch box 23 in gear for operating the
scroll 10 for working the embroidering shuttles; the cam 22 is fixed on the scroll
shaft; cam 22 being loose on shaft, and provided with slot and bolt by which its
position in relation to cam 22ª is fixed and determined so as to time the
movements of the levers 21, 21ª. For example, as shewn by Drawings, Fig. 3,
the vertical catch 20 having lever carried up by lever 21 the bell crank lever 24
moving on stud 25 will, by the rod 26, turn the lever 27 on its fulcrum 28, and by
means of arm 29 and coupling 30 force in gear the clutch 23; meanwhile the arm 31
of the lever 27 by connecting rod 32 actuates lever 33 on its fulcrum 34, its outer
end 35 separating the part 36 of clutch 37, so that the embroidering shuttles being

page_text: operated by the scroll 10 the ordinary shuttle operated from picking stick shaft 38
is thus automatically put out of gear, and when the vertical catch 19 is caught by
the rocking lever 21a the bell crank lever 39 and connecting rod 40 secured at 41
will separate or throw out of gear the clutch 23, and put into gear the catch box
36, 37, on picking stick shaft by means of connections 32, 33, 35; 33ª is a lever
corresponding to lever 33, and operates a like clutch box to 36, 37, on the other
side of the loom.
Having thus fully described the nature and particulars of this my said Invention,
together with the manner in which the same is to be or may be performed or
carried into practical effect, I would have it understood that I lay no claim to
any of the parts when considered separately; what I do claim is,-
Firstly. The use of the guard 3 for levelling the warp in combination with the
appliances for lowering the shuttles, constructed and applied in the manner and
as herein described and illustrated.
Secondly. The combination of parts comprising cam 4, levers 5 and 6, connecting
rod 7, for purpose herein fully described and as illustrated by Drawings.
Thirdly. The combination of parts comprising scroll. 10, lever 11, stud 12, and
connections 13, 14, for the purpose herein described and as illustrated.
Lastly. The combination of the several parts whereby the clutch box 23 is
controlled so as at all times to be out of gear when the clutch box 36, 37, is in
gear, and vice versa, as herein fully described and substantially as illustrated by
the Drawings hereunto annexed.
In witness whereof, I, the said Herbert Anderton Foster, have hereunto set
my hand and seal, this Twenty-seventh day of September, in the year of
our Lord One thousand eight hundred and eighty one.
