We, HENRY LOCKWOOD, ARTHUR LOCKWOOD, JOSIAH LOCKWOOD, HIRAM
HERBERT LOCKWOOD, and GEORGE HENRY Lockwood, trading as George Henry
and Company, of Britannia Chambers, St. George's Square, Huddersfield, in the
County of York, Woollen and Worsted Manufacturers, and JONAS BROOK
COLDWELL, of Ingfield Terrace, Linthwaite, near Huddersfield aforesaid, Loom
Tuner, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in looms for weaving purposes, and its
object is to actuate and operate by electricity the shuttle, shuttle boxes, and
healds or heddles.
According to this invention the shuttle is provided or armed with an armature
of soft iron, or a permanent steel magnet or an electro-magnet, let into the sole
or underside of the shuttle which may or may not be provided with wheels
or runners.
The shuttle race of the slay or "going part" of the form is formed of or lined,
or covered with any suitable non-conducting or non-magnetic, material of any
suitable thickness. Under the layer of non-conducting or non-magnetic material,
or let into the shuttle race itself are provided a number of electro magnets at
suitable distances apart, so as to extend wholly across or the full length
of the said race. The electro-magnets are each connected electrically
to a terminal or button which in turn are electrically connected with a
terminal or button on a switch plate which is connected with a dynamo or other
electric generator. One portion of each electro magnet in the shuttle race is
also connected by a wire to the dynamo or other electrical generator. On the
face of the switch plate is mounted a switch finger or lever which is operated
from some moving part of the loom for successively conveying the currents to
the electro-magnets whereby an electro-magnetic wave is produced for reciprocat-
ing the shuttle across the race. When it is required to reciprocate the shuttle
in the opposite direction the switch finger or lever is operated in the opposite
direction. The electrical connection with the electro-magnet in shuttle is made
through the reeds as follows:-
The said electro-magnet in the base of the shuttle is surrounded by a coil
or coils. One end of wire forming the coil or coils of said electro magnet is con-
nected with a plate of brass or other conducting substance let into the back
of the shuttle near to the top of the shuttle, whilst the other end of the coil is
connected to a similar plate let into the back of the shuttle near its bottom.
Both of the said plates are made to run almost the entire length of shuttle.
Over the top of the warp and hehind the reed is a rod arranged to run the full
length of the shuttle race. A second rod is also made to run behind the reed

page_text: and under the warp. The rods are each provided with suitable wire or other
connectors arranged at suitable distances apart. The wire or other connectors
are arranged in such a position that as the shuttle race moves backwards for the
shuttle to pass, the connectors project through the reeds and come in contact
with said plates let into the back of the shuttle. When the shuttle has passed
through the warp and the reed moves forward to lay the weft the connectors are
withdrawn, thus allowing only the reed to touch the weft. The two said rods
are connected by wires with the dynamo or other electric generator in such a
manner that the current passes, say, to the upper rod, thence respectively and
consecutively to its connectors upper plate in shuttle, round the electro-magnet
in shuttle, then to the bottom plate in shuttle, through the connectors to the
lower rod and from thence back through its wire connection to the dynamo or other
generator.
For operating the healds or heddles as well as the shuttle boxes, we provide at
one or both ends of the loom a number of levers which is or are suitably ful-
crummed to the framework thereof. Each lever is provided, say at the back
thereof, with two projections which are formed into electro-magnets and are
connected to switch board or plate which in turn is connected to the dynamo or
other electric generator. The switch board is provided with the required
number of terminals, and a switch finger or lever capable of being operated from
or controlled by some moving part of the loom, such as, say, the ordinary
perforated sheets or lags.
Opposite to each of the said two electro-magnets is fixed a powerful electro-
magnet connected to the dynamo or other electric generator and arranged to act
upon the whole of, or a portion of the electro-magnets attached to the backs of
the fulcrummed levers. The opposite ends of the levers are respectively operated
upon by reversing the polarity of the electro-magnets. The ends of the levers
at both ends are connected by cords, chains, or their equivalents passing over
suitable pulleys or guides to the healds or heddle shafts, and the latter will be
raised or lowered according to which ends of the levers are operated upon.
When one or more solenoids are employed for operating purposes then in some
cases it may be found necessary to employ one or more additional levers which
may be arranged below the heald or heddle shafts.
A similar arrangement of electro-magnets, switches, and levers or solenoids to
that employed for operating the healds or heddles may also be employed for
operating the shuttle boxes.
By our improvements we are enabled to dispense with the present picking
motion and its accompanying wear and tear; as well as reducing the noise and
jar in working the loom. Dispensing with the harness chains for operating the
shuttle boxes, and the attendant dirt and inconvenience. Besides which there is
a great saving of time and power, increase of speed and smoothness in the running
of the loom, in addition to reducing the cost of its manufacture by reason of the
simplification of its parts.

We, HENRY LOCKWOOD, ARTHUR LOCKWOOD, JOSIAH LOCKWOOD, HIRAM
HERBERT LOCKWOOD, and GEORGE HENRY LOCKWOOD, trading as George Henry
and Company, of Britannia Chambers, St. George's Square, Huddersfield, in the
County of York, Woollen and Worsted Manufacturers, and JONAS BROOK
COLDWELL, of Ingfield Terrace, Linthwaite, near Huddersfield aforesaid, 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 improvements in looms for weaving purposes, and its
object is to actuate and operate by means of electricity the shuttle, as well as the
shuttle boxes and healds or heddles, thereby simplifying the construction and
number of working parts of the loom.
The above object is attained by mechanism illustrated in the annexed drawings,

Figures 1, 2, 3, 4, and 12 are drawn to a smaller scale than the remainder of
the views.
Like parts in all the views are marked with similar letters of reference.
In the drawings the invention is shown applied to what is known in the United
Kingdom of Great Britain and Ireland as the "Knowles and Hollingworth loom."
A is the framework of the loom. B the lay sword or levers on which the

page_text: shuttle race C is mounted and fixed. 1) the reed attached to and reciprocating
with the shuttle race. E the stop rod lever or finger. F the shuttle box
attached to the lay swords B at each end of shuttle race C. G the chains passing
over pulleys H for raising and lowering the shuttle boxes. I the crank shaft
mounted in bearings on the framework. J, K, are respectively fast and loose
pulleys mounted directly upon the end of the crank shaft instead of the ordinary
side drive as at present.
All the above named parts, with the exception of the shuttle race, (which is
constructed as hereafter described), may be of the ordinary construction and
operate in the usual manner.
L is the shuttle, which is provided with an armature M of soft iron, or a per-
manent steel magnet, as at Fig. 7. Or an electro-magnet may be used in place
thereof, as at Fig. 8. The armature M, or the permanent steel magnet, is in
the form of a piece of flat iron or steel let into the sole or underside of the shuttle,
as at Fig. 7. But when an electro-magnet is employed it is made with two arms
or poles, and it is let into the shuttle and arranged transversely as shown at Figs. 8
to 10. The shuttle L may, or may not, be provided with wheels or runners 86,
as shown at Figs. 8 and 10.
The shuttle race C of the slay or "going part" of the loom is formed of any
suitable non-conducting, or non-magnetic material, such as wood, or it may be
lined or covered with any non-conducting, or non-magnetic material, such as
vulcanized fibre, ebonite, or the like of any suitable thickness.
Under the layer of non-conducting or non-magnetic material, or let into the
shuttle race itself, as shown at Fig. 3, are provided a number of electro-magnets N
of ordinary construction at suitable distances apart, so as to extend wholly across,
or the full length of the said race C. The electro-magnets N are each made in U
form and arranged transversely in the said shuttle race C, and the corresponding
ends of the wires of each electromagnet are connected electrically to a terminal,
or button 67, shown in the drawings at Fig. 3, and connected by means of an
insulated copper wire R which, after being grouped with other similar wires, is
led through a flexible tube 0 of non-conducting material, -see Fig. 3,-to the
corresponding terminal or button P' on a switch plate Q (see Fig. 11). The
number of buttons, or terminals P on the switch plate Q correspond with the
number of electro-magnets N in the shuttle race C, and they are either let into a
switch plate of insulated material, or separately insulated therein. The other
end of wire or terminal of each electro-magnet N in the shuttle race is also
connected by a wire S to the dynamo or other electrical generator, so
to provide means for forming a complete circuit when required. On the face of
the switch plate Q is mounted a switch finger or lever T (suitably bushed with
insulating material or otherwise insulated to prevent the electric current from
passing down the shaft V) which is operated from some moving part of the loom
to be presently described, and connected electrically to the contrary terminal of
dynamo from that which the wire S is connected to, for successively conveying
the currents to the electro-magnets N whereby an electro-magnetic wave 1S
produced for reciprocating the shuttle L across the race C.
as
For operating the switch finger or lever T similar mechanism to that shown
at Fig. 12 is employed, that is to say;-To the framework A is fixed the bracket U
in which is mounted the vertical shaft V on the upper end of which is mounted
the switch lever or finger T arranged to be intermittently rotated over the switch
plate fixed to the top of bracket U. On the shaft V is mounted so as to
slide freely on a key or feather fixed thereon, a boss W provided with a circum-
ferential groove X at or about its centre, and armed at each end with a bevel
wheel Y, Z, arranged with their teeth to face each other. An intermittent rotary
motion is imparted to the shaft V from the crank shaft I through a spur sector 1,
provided with sufficient teeth to rotate the finger T completely round the switch
plate Q, and then to allow it to remain at rest until again required,-fixed to the
face of a spur wheel 2 mounted on the end of the crank shaft. The spur sector 1

page_text: intermittently gears with a spur wheel 3 mounted on the end of an intermediate
horizontal shaft 4. On the opposite end of shaft 4 is mounted a bevel wheel 5
arranged to gear with one of the bevel wheels Y or Z at a time. When the bevel
wheel 5 is in gear with wheel Y the finger T will be rotated in one direction. But
when it is required to reciprocate the shuttle in the opposite direction the switch
finger or lever is operated in the opposite direction by causing the wheel 5 to
gear with wheel Z, thereby providing means for controlling and regulating the
current for reciprocating the shuttle L in either direction.
The requisite motion for effecting the changing of the wheels Y and Z and
placing them in gear with wheel 5 is imparted thereto and controlled by the
movement of the picking lever 6 (pivoted to the shaft carried in bearings on
the framework) by means of horizontal connecting rod 7, double ended lever 8
pivoted to framework A, vertical connecting rod 9, lever 10 mounted on one end
of rocking shaft 11,--carried in bearings on the framework A,-lever 12 on
opposite end of shaft 11 and provided with a bifurcated end arranged to engage
with the circumferential groove X in the boss W.
The electrical connection with the electro-magnets M in shuttle L is made
through the reeds as follows:-
The said electro-magnets M in the base of the shuttle are surrounded by a coil
or coils 13. One end of wire forming the coil or coils 13 of said electro-magnets M
is connected with a plate of brass 14 (Fig. 10) or other conducting substance
let into the back of the shuttle near to the top of the same, whilst the other end
of the coil 13 is connected to a similar plate 15 also let into the back of the shuttle
near its bottom. Both of the said plates are made to run almost the entire length
of the shuttle with one of their ends (opposite ends of the plates) at a short
distance from the respective magnets as shown. The two magnets are in one
circuit. Over the top of the warp and behind the reed D) is a rod 16,-Figs. 4
and 5, carried in insulated bearings attached to the lay swords B, and arranged
to run the full length of the shuttle race C. A second rod 17,-carried in insulated
bearings attached to the lay swords B,-is also made to run behind the reed and
under the warp. The rods 16 and 17 are each provided with suitable wire or other
connectors 18 and 19, Figs. 4 and 5, arranged, say, in loop form and at suitable
distances apart as shown at Fig. 3. The wire or other connectors 18 and 19
are arranged in such a position that as the shuttle race moves backwards for the
shuttle to pass, the said connectors project through the reeds and come in
contact respectively with plates 14 and 15 which are let into the back of the
shuttle. When the shuttle has passed through the warp, and the reed moves
forward to lay the weft, the connectors 18 and 19 are withdrawn from between
the reeds by means of the forward movement of the reed and the lever connection
arranged as follows:-
On the ends of each of the rods 16 and 17 is mounted and fixed a double ended
lever 20 and 21 but insulated therefrom. The two ends of each lever 20 and 21
are arranged at or about a right angle to each other, and the two levers are
connected as follows:--
-A
The horizontal arms of each lever are connected together by the spring 22,
whilst the two pendant and vertical ends of said levers are jointed to links 23 and
24, which in turn are jointed to a central horizontal link 25. The outer end of
link 25 is secured to the framework A. As the reed 1) moves forward in the direc-
tion of arrow (Fig. 5) the pendant arms of the levers will be drawn by means of
their connection with links 23, 24, and 25, from the reed D, and by their move-
ment will cause the rods 16 and 17 to oscillate in their axial bearings and to
move the connections 18 and 19 simultaneously clear of the reeds D, thus allowing
only the reed to touch the weft. The spring 22, on the return of the reed, returns
the connectors to the position shown in the drawings. The two rods 16 and 17
which are insulated in their bearings as well as regards each other, are connected
by wires 26 and 27 with the dynamo or other electric generator in such a manner
that the current passes, say, to the upper rod 16, thence respectively and consecu-

page_text: tively to its connectors 18, upper plate in shuttle 14, round the electro-magnet M
in shuttle, then to the bottom plate 15 in shuttle, through the connectors 19 to
the lower rod 17 and from thence back through its wire connection 27 to the
dynamo or other generator.
The shuttle may be so arranged as to be attracted by the first magnet N
arranged at each end of the race C whenever the switch finger T commences to
move in either direction over the switch plate Q thereby drawing the shuttle
forwards and starting it on its flight across the shuttle race. Or if preferred, a
shuttle starting lever 28 may be employed and arranged as follows:-
At each end of the shuttle race C, and at the extreme end of each shuttle
box F, and suitably fulcrummed to the shuttle race C, is mounted a lever 28,
hereafter termed the shuttle starting lever, having a suitable face and armed or
provided with a soft iron armature 29.
In or on each end of the shuttle race C is mounted one or more electro-
magnets 30, (which is energized automatically by connecting it to the switch
plate in a similar manner to that herein before described for the electro-magnets N
in the shuttle-race) arranged horizontally, in order to act upon the soft iron arma-
ture fixed to the shuttle starting lever 28 for drawing or attracting the latter
forward against the outer end of the shuttle and for pressing or pushing the
latter forward, until the first electro-magnet N (at each end of the shuttle-race)
is respectively brought into action, and the shuttle made to complete its flight
across the race.
For operating the healds or heddles 31, Fig. 1, as well as the shuttle boxes F,
at one or both ends of the loom is provided with a number of levers 32 which is
or are suitably fulcrummed at or about their centres to the before named shaft (*
carried in bearings on the framework A. Each lever 32 is provided, say at the
back thereof, with two projections 33 and 34 which are formed into electro-
magnets wound in such a manner as to have like poles simultaneously, and they
are connected to switch board or plate 44 (Fig. 15) by wires 35 and 36) respectively
to the upper and lower plates 37 and 38 (made of spring or flexible brass) of the
tilting current reversing block 39 interposed between the electro-magnets 33
and 34 and the dynamo or electrical generator. Between the ends of plates 37
and 38 are respectively inserted the rods 40 and 41,-suitably attached to the
switch board 44 by insulated bearings,-which are connected by wires 42 and 43,
-şay wire 42 to rod 40 and wire 43 to rod 41-to the dynamo or other electric
generator. The switch board 44 (which may be made of wood, or other non-
conducting material, is provided with the required number of terminals 45, and
a switch finger or lever consisting of the brass or metal plates 37 and 38 with
ebonite or other insulating block 39 intersposed between them and mounted upon
shaft 47, capable of being operated from or controlled by some moving part of
the loom, such as, say, the ordinary perforated sheets or lags 46, Fig. 1, to which a
rotary motion is imparted from crank shaft I through spur wheel 2 (Fig. 2)
mounted thereon to spur wheel 48 (which gears therewith), bevel wheels 49 and 50
respectively mounted on shafts 51 and 52, bevel wheels 53 and 54 and lag
cylinder 55 carried in bearings on the framework.
Or an intermittent motion may be imparted to the lag cylinder shaft 55 by the
arrangement shown at Figs. 13 and 14 as follows:-
Instead of making the shaft 52 in one portion as at Fig. 2, it is made in two
separate portions 52 and 79, the upper part of shaft 52 being armed with a disc
plate 80 provided with a circular projecting ring 81 and a projecting pin 82. An
opening 83 is formed in the circular ring 81 adjacent to the pin 82. On the
lower end of the shaft 79 is mounted a star wheel 84 having say, four radiating
slots 85 arranged to engage with the pin 82. The space between the slots is
curved to fit the periphery of the ring 81. The bevel wheels 53 and 54 are respec-
tively mounted upon the lower end of shaft 52 and upper end of shaft 79 so that
whenever the pin 82 and one of the slots 85 are in engagement, motion will be
imparted to the lag shaft 55 and lag sheet 46.

page_text: Opposite to each of the said two electro-magnets 33 and 34 on levers 32 is
fixed a powerful electro-magnet 56 (fixed to, but insulated from framework A)
extending across the whole of heald levers 32, picking lever 6, and the shuttle
box levers 57, (all of which levers are pivoted on the shaft 6*), and it is
connected to the dynamo or other electric generator by wires 58 and 59, and
arranged to act upon the whole of, or a portion of the electro-magnets 33 and 34
attached to the back of the fulcrummed levers 6, 32 and 57.
The opposite ends of the levers 6, 32 and 57 are respectively operated upon by
reversing the polarity of the electro-magnets 33 and 34 on levers 6, 32 and 57,
whenever the current reversing blocks 39 are tilted for the respective ends of
plates 37 and 38 to come in contact with rods 40 and 41. Thus, say, if the polarity
of the electro-magnets 33 and 34 is N when the underside of plate 37 is in
contact with rod 40 and the upper surface of plate 38 in contact with rod 41
as at Fig. 16, then the polarity of the electro-magnets 33 and 34 will be changed
to S when the upper surface of plate 38 is in contact with rod 40, and the under
surface of plate 37 in contact with rod 41. The tilting of the plates 37 and 38
is operated and controlled by pegs 60, in the lag sheet 46, which are pressed well
into contact with the plates 37 and 38, and the flexibility of the latter permits the
pegs to pass.
One set of plates 37 and 38, and insulated tilting block 39 is provided for each
of the levers 6, 32, and 57,-that is one set for each of said levers, and they are
each separately electrically connected to a terminal or button 45 of the switch
board 44.
The ends of the levers 32 at both ends are connected by cords, or chains 61,
or their equivalents passing over suitable pulleys or guides 62 to the healds or
heddle shafts 31, and the latter will be raised or lowered according to which
ends of the levers are operated upon. Whilst levers 57 are connected by rods 63
to the box levers 64,-fulcrummed to framework A, thence by chains & passing
over pulleys H and attached to rods 65 which in turn are connected at their
upper ends to ordinary guides 66 fixed to the shuttle boxes F in the usual manner.
Other parts of the loom not shown or described, with the exception of the
Jacquard which is dispensed with, may be of the usual and ordinary construction.
The action if the loom is as follows:-
The loom having been tuned in the usual manner, the required number of
shuttles having been placed in the shuttle boxes F, and the electric current from
the dynamo or other electrical generator switched on to the required parts of the
loom, the loom is then set in motion by throwing the belt off the loose pulley K
on to the fast pulley J, a reciprocating motion being imparted to the shuttle
race C and the reed D from the crank shaft I in the usual manner.
The shuttle L is either started in its flight across the race C by the shuttle
starting lever 28, or else it is drawn forwards by the electro-magnet N,-in
shuttle race C nearest to the shuttle box F containing the shuttle to be actuated,―.
acting upon the magnet M in the shuttle.
After the shuttle has once been started in its flight each electro magnet N will
be successively energized as the switch finger T rotates over the terminals P of the
switch plate Q for completing their respective circuits, and for causing them to
act upon the magnet M for drawing the shuttle forwards.
The
When permanent or electro-magnets are employed in the shuttle L a double
switch finger is used in place of the single switch finger T shown in the drawings,
and which is used when a soft iron armature is employed in the shuttle.
distance between the points of the double fingers being arranged so that the
electrical communication will be made with the magnets N in the shuttle race
by the first point of the switch finger directly in front of the first poles of the
magnets M in the base of the shuttle at its front, and by the second point of said
switch finger directly behind the last poles of the magnet M in said shuttle at
its rear. Thus, as the switch finger rotates in one direction a double wave

page_text: or two waves of magnetism is or are sent across the shuttle race.
The polarity
of the front wave being opposite to the front poles of the magnet M in shuttle
attracts, and the polarity of the second wave being of like kind to the front wave
and of like kind to the latter poles of the magnets M repels, thereby causing
the shuttle to be both drawn as well as driven across the said race. When the
travel of the shuttle is required to be reversed, the direction of the energizing
current is reversed by inserting in the circuit any ordinary current reverser and
actuating it from the picking lever 6.
Simultaneously with the energizing of the electro-magnets N in the shuttle
race C, the magnets or electro-magnets M in the shuttle will have the electric
current conveyed to and from them respectively through the rods 16 and 17 at the
hack of the reed D, connectors 18 and 19, and plates 14 and 15 let into the back of
the shuttle as previously described. The connectors 18 and 19 are so arranged
and operated that they are withdrawn from between and clear of the reed
immediately the shuttle has completed its flight across the race C and during
the time the latter is completing the "lay" of the weft thread. As soon as the
race C returns to its normal position the connectors 18 and 19 will by the action of
the spring 22 acting upon the ends of the levers 20 and 21 be passed again
through the reeds D across the race C ready for the next flight of the shuttle.
When the shuttle is travelling in one direction, say from left to right, bevel
wheel Y will be in gear with bevel wheel 5,-which, as previously described,
receives an intermittent rotary motion from the crank shaft I, through spur
sector 1, spur wheel 3, and the intermediate shaft 4,-for rotating the switch
finger T over the terminals or buttons P of the switch plate Q. During the time
the shuttle remains in its box F, or during the change of the shuttle boxes,―
which in either case takes place whilst the spur sector 1 is out of gear with
spur wheel 3, the bevel wheel Y is moved-by the action of the magnet 56 upon
the projections 33 and 34 of the picking lever 6,-the wheel Y is thrown out of
gear with wheel 5 and the bevel wheel Z thrown into gear therewith, thus causing
the switch finger T to rotate in the opposite direction over the terminals or
buttons P for successively energizing the electro-magnets N in the reverse order,
that is, say, from right to left, for causing the shuttle to traverse in, say, that
direction across the race C.
The changing of the healds or heddles shafts 31 also takes place during the time
the bevel wheels Y and Z are being respectively thrown in and out of gear with
the bevel wheel 5, and immediately after the weft thread has been "laid" by the
reed D, by means of the electro-magnet 56 acting upon the projec
tions 33 and 34 of the levers 32. The projections 33 and 34
(being wound to form electro-magnets as previously described) on the levers 32
which are desired to be operated are energized as required by the pins of the
moving lag sheet 46, as they come in contact with the underside of plate 38,
which pins are so arranged as to vary its position to the rods 40 and 41, and
according to the position of the plates 37 and 38 and their points of contact with
said rods 40 and 41 .will the electric current be conveyed to the said electro-magnets
for drawing the end or ends of one or more of the desired levers 32 to the
electro-magnet 56, or repelling it or them therefrom, thus changing the position
of the healds or heddle shafts 31 as desired.
The other parts of the loom operate in the ordinary and usual manner.
By our improvements we produce a loom that is partly operated by say, ordinary
means, and partly by electricity, and at the same time we are enabled to dispense
with the present picking motion and its accompanying wear and tear; as well
as reducing the noise and jar in working the loom. Dispensing, also, with the
harness chains for operating the shuttle boxes, and the attendant dirt and in-
convenience. Besides which there is a great saving of time and power, increase
of speed and smoothness in the running of the loom, in addition to reducing the
cost of its manufacture by reason of the simplification of its parts.

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: -
1. In a loom, such as herein described, for weaving woollen, textile, and other
fabrics or materials, a shuttle actuated by electrical means substantially as
herein described, and having two electro-magnets let transversely into its sole
at suitable distances apari, and two metal conducting plates let into its back
in a longitudinal direction and parallel with each other, the end of the said
top plate being in contact with one of said electro-magnets, and the opposite end
of the said lower plate in contact with the other electro-magnet, all com-
bined and arranged substantially as herein described and illustrated and for the
purposes set forth.

at suitable distances apart and connected separately to the terminals of a switch
plate, and to the dynamo, so as to be capable of being successively energized
during the rotation of the finger of the switch plate, said rotating finger being
connected to the dynamo, and the means as described for actuating the said finger
from some moving part of the loom, all arranged substantially as described and
