of Lancaster, Dentist, for the Invention of "IMPROVEMENTS IN HEALDS FOR
LOOMS, AND IN MACHINERY OR APPARATUS FOR MANUFACTURING AND
THE SAME UPON 'SHAFTS,'"
WINDING
Sealed the 25th July 1865, and dated the 7th February 1865.
PROVISIONAL SPECIFICATION left by the said Alfred Augustus Larmuth
at the Office of the Commissioners of Patents, with his Petition, on
the 7th February 1865.
I, ALFRED AUGUSTUS LARMUTH, of Salford, in the County of Lancaster,
Dentist, do hereby declare the nature of the said Invention for "IMPROVE
MENTS IN HEALDS FOR LOOMS, AND IN MACHINERY OR APARATUS
FACTURING AND WINDING THE SAME UPON 'SHAFTS," " to be as follows:-
F03 MANU-
My invention relates to those healds which are produced by twist-
ing two or more strands of wire together, and forming loops to con-
stitute the necessary eyes; and consists, firstly, in applying solder or other
cementing material to the said eyes for the purpose of uniting the strands
of metal at the boundaries thereof; and, secondly, in forming the eyes
in continuous lengths of wire, which are subsequently wound in a spiral
form upon the shafts.
Another part of my Invention relates to machinery for making and
winding such healds as aforesaid, the general features thereof being
that the wires are drawn from bobbins, twisted, formed with eyes,
.

page_text: soldered, and wound upon shafts in a continuous length by successive
automatic operations. The bobbins containing the wire from which the
healds are to be made are mounted upon a disc, and from thence the
wires are conveyed to another disc provided with notches for Lolding
them. The bobbins being caused to revolve bodily effect a twisting of
the wires on one side around a punch, which is thrust between the two
strands, and by which means the eye is partially formed. After which
the notched disc is caused to revolve in the opposite direction, whereby
a contrary twisting is effected upon the other side of the punch. The
eye is thus in a certain degree completed, and the opposite twistings
have the effect, of counteracting each other, and of causing the eyes to
lie flat. The eye is then drawn onward, is flattened and shaped by a
descending punch, and is then after having been cleaned by acid or other
suitable substance depressed into fluid solder, and tapped on its removal
to shake off the superabundant quantity. The next operations are the
preparation of the wood shafts for receiving the finished healds, and
winding them thereon. The shafts are mounted in discs which have an
intermittent rotatory motion. At each of these movements a circular
saw is caused to cut a notch for the reception of the wire healds, and
a screw moves the shafts at intervals longitudinally, whereby series of
such notches are cut. In these the healds are wound in a continuous
spiral form by the intermittent rotatory motion above described.
Another part of my Invention relates to improvements upon a Patent
granted to me, bearing date January 31st, 1860, No. 248. I now pro-
pose to manufacture such healds as are therein described, and to wind
them on to the shafts by a modification of the machinery above de-
scribed. With this view I dispense with the twisting apparatus of this
my present Invention, and draw the wire from a stationary bobbin, after
which it is by successive operations as herein-before described punched
to flatten it, and to make the eyes, dipped into solder or other coating
material, and wound upon the shafts.
SPECIFICATION in pursuance of the conditions of the Letters l'atent, filed:
by the said Alfred Augustus Larmuth in the Great Seal Patent
Office on the 7th August 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME. 1, ALFRED 3
AUGUSTUS LARMUTH, of Salford, in the County of Lancaster, Dentist,
sends greeting.

the Channel Islands and Isle of Man, an Invention for "IMPROVEMENTS IN
HEALDS FOB Looms, AND IN MACHINERY OR APPARATUS FOR MANUFACTURING AND
WINDING THE SAME UPON SHAFTS," upon the condition (amongst others) that I
the said Alfred Augustus Larmuth, by an intrument in writing under
my hand and seal, should particularly describe and ascertain the nature
of the said Invention, and in what manner the same was to be performed,
and cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
I
NOW KNOW YE, that I, the said Alfred Augustus Larmuth, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement and accompanying Drawings, that is to
say:-
My Invention relates to those healds which are produced by twisting
two or more strands of wire together, and forming loops to constitute
the necessary eyes; and consist, firstly, in applying solder or other
cementing material to-the said eyes for the purpose of uniting the strands
of metal at the boundaries thereof; and, secondly, in forming the eyes
in continuous lengths of wire, which are subsequently wound in a spiral
form upon the "shafts."
Another part of my Invention relates to certain machinery for making
and winding such healds as aforesaid.
.:
In the accompanying Drawings, Fig. 1 represents a heald of that
description to which the first part of my Invention refers, drawn upon
an enlarged scale, it being composed of two strands of wire twisted to-
gether, but leaving a space a for the eye; such healds are already known,
and are not therefore now claimed by me; but my Invention consists.in
applying solder or other cementing material from c to d, whereby the
wires become firmly united, and a smoother eye is obtained..
The second part of my Invention is shewn at Fig. 2 in side elevation,
at Fig. 3 in partial plan view; Figs. 5, 6, and 7, are detached views of
some important parts. The machine I am about to describe is designed

page_text: to twist the wires which are drawn from bobbins, to form them with the
required eyes, solder them, and wind them upon shafts in a continuous
length by succesive automatic operations; and I shall in the first place
point out how motion is communicated to the several operating parts,
and subsequently described the general operation of the machine. The
main shaft is at 1, to which motion is communicated from the prime
mover through the pulley 2, this pulley is however loose upon the shaft 1,
which it drives through the medium of a cone 3, fitting into a hollow
cone on the said pulley. The cone 3 is mounted with a feather upon the
shaft 1, and is capable of being slidden in and out of contact with the
pulley 2 by means of the lever 4, and the motion of the main shaft may
therefore be readily arrested at any time by sliding the stop rod 5
which is connected to the lever 4. Upon the main shaft 1 is a pinion 6,
driving a wheel 7 mounted upon a line shaft 8 from which the various
parts of the machine hereafter to be described are actuated. Upon this
shaft is a spaced wheel 9, a portion only of its circumference being. pro-
vided with teeth. This wheel when its teeth are in gear, drives a wheel
10 upon a short shaft 11 upon which is another wheel 12 giving motion
by means of a carrier 13 to a wheel 14, and this through the medium
of a carrier 15 communicates motion to a pinion 16 mounted upon a
spindle 17, which is capable of turning in bearing 18 carried by the
framework of the machine. Upon the spindle 18 are the two bobbins
19 which carry the wires to be twisted together to form the healds; by
the arrangement above described it will be seen that the spindle 18, to-
gether with the bobbins, are caused to revolve much more rapidly than
the line shaft 8, and with an intermittent motion, for as such motion
is communicated through the spaced wheel 9 it will take place during a
portion only of the revolution thereof. The wires. to be twisted pass
through holes formed in a small disc 20, which is provided with a rod
passing into the spindle 17, but the said disc is constantly forced out-
ward by a spring placed within the socket formed in the spindle. Upon
the line shaft 8 is a spaced wheel 21, that is a wheel with teeth around
a portion of its circumference only, as in the case of the wheel 9. This
wheel 21 gears into a wheel 22 mounted upon a stud carried by a bracket
23 and driving a pinion 24 mounted upon a tube 25 capable of turning in
the bracket 23. Upon an end of this tube is fitted a plate 26 carrying
certain parts hereafter to be referred to, but not shewn in Fig. 2, at the
other end is a pulley 27 around which a weighted cord 28 is wound. As
the line shaft 8 revolves the teeth on a portion of the circumference of
the wheel 21 will by imparting rotatory motion to the tube 25 through
the medium of the wheel 22, cause the pulley 27 to wind up the weighted
cord 28, but when the teeth on the portion of the circumference of the

page_text: wheel 21 pass out of gear, then the weighted cord 28 will be at liberty
to turn back the tube 25, and consequently the plate 26
I now proceed to describe the apparatus which is carried by the plate
26, referring to the detached Figures 4 and 5, and premising that the
combined operations will hereafter be explained. The face of the plate
26 is provided with a V groove, within which is a sliding piece 29 drawn
downward by a spring 30 passing over two studs 31, 32, the former of
which is fixed to the sliding piece 29, and the latter to the plate 26, a
slot through the piece 29 being provided to allow it to pass. At the
back of the plate 26 is an arm 33 turning upon a centre 34, one end of
this lever is provided with a pin which passes through the plate 26,
and, presses against the sliding piece 29, the other end of the lever 33
being forced outward by a spring 34. When the sliding piecé 29 is
moved outward from the centre of the tube 25, as will be explained;
the pin on the lever 33 passes into a recess in the said sliding piece,
and keeps it therefore in its outward position, but when the lever is
turned upon its centre against the spring 34 then the sliding piece 29 is
at liberty to be drawn inward by the spring 30. The face of the plate
26 is also provided with a second V-groove, within which is a sliding
piece 35 drawn upward by means of an india-rubber ring 36, one end
of which is hooked on to the said sliding piece, and the other passed
over a stud 37. This sliding piece however is prevented at certain times
from being drawn upward through the force of the spring 36 by a lever
38 turning upon a centre 39, its outward end passing into a notch in the
said sliding piece, and in this position the lever is retained by means of a
spring 40. Upon the sliding piece 35 is an incline 41, which when the
said piece moves upward, arrives against a lever 42, turning upon a
centre 43. The other end of this lever has a pin 44, situate over one end of
a lever 45 turning upon a centre 46; when therefore the sliding piece 35
is moved upward, the incline 41 acting against the lever 42 causes the
pin 44 to turn the lever upon its centre 46, so that its inward end is pro-
jected outward, and this inward end arriving against the disc 20 carried
by the spindle 17 and above referred to, forces the said disc backward
against the force of the spring which pushes it forward. Upon the face
of the wheel 22 is an inclined tappet 47, which, as it revolves, presses the
end of the lever 33 inward against the face of the spring 34, the other
end of the said lever is therefore turned outward, and by removing its
pin from the recess in the said sliding piece 29 allows that sliding piece
to be drawn inward by the spring 30. Upon the wheel 22 is also an
incline 47*, against which at a certain period a projecting end of the
sliding piece 29 arrives, whereby the said sliding piece is drawn upward
again, in-which position it is retained by the pin on the lever 33. Upon

page_text: the wheel 22 is an inclined tappet 48, which, as the said wheel revolves;
arrives in contact with an end of the lever 38 which projects through
the plate 26, whereby the said lever is forced outward on its centre 39,
being thus removed from the notch in the sliding piece 35, and allowing
the said sliding piece to move upward by the force of the spring 36. The
return of the sliding piece is effected by an arm 49 on the wheel 22;
and against which the said sliding piece arrives, whereby it is pressed
down and the lever 38 is allowed to pass into the notch thereof. Upon
the line shaft 8 is a cam 50, which acts against the sliding bolt 51
mounted in guides 52, and which is pressed in contact with the cam.50
by a spring 53. The lower end of this bolt carries a punch 54 which
is designed to perfect the shape of the eye, and which when it is forced
downward by the cam 50, passes into a die formed in two parts, 55, 56,
(see the detached view, Fig. 2*,) pressed towards each other by springs
57, 58. This die is provided with a recess 59, and through which the
the partly finished eye passes. When the punch 54 descends it separates
the two parts of the die and passes through the recess 59, and con-
sequently through the heald eye contained therein. At 60 is a cam on
the line shaft 8, actuating a sliding rod 61. The lower end of the rod
61 is connected to a short lever 62 fixed to a shaft on which there is an
arm 63, the two ends of which abut against levers 64, 65, turning on
centres 66. These levers are drawn together at the opposite end to
rollers 67 by a spring 68, and the said rollers therefore have a tendency
to keep apart, but when the rod 61 is depressed by the cam 60, the
arm 63 pressing against the said levers causes the rollers 67 to advance
towards each other and press against the eyes of the twisted wires which
are passing between them. The lower roller 67, when in the position.
shewn, is in contact with any suitable substances, such as muriate of
zinc, used to assist. soldering, and this substance is therefore conveyed
to the wires when the rollers are brought together, as above described.
Upon the shaft 8 is another cam 69 acting against a plunger 70 which
is held in contact with the said arm by a spring 71; this cam acting at
intervals presses the formed eye into a vessel 72 containing molten
solder, which is kept in that condition by a gas jet issuing from the
pipe 73. At 74 is a band passing over the shaft 8 and over a pulley
75 mounted upon a stud and carrying tappets 76, which tappets act
against. levers 77 mounted upon a centre at 78; when these levers are
liberated they fall upon the heald while the solder is yet in a partially
fluid state, and shake any superfluous quantity therefrom. At 79 is a
cam acting against a flat punch 80, kept in contact with the said canı
by a spring 81, and beneath the punch is an anvil 82 upon which the
twisted wires are flattened for the purpose of causing them to fit

page_text: regularly into the shafts as hereafter to be described, and thus keep. the
eyes when wound in one direction.
.
Having thus described the construction of the several parts used for
twisting the wire and completing the eyes, I will now proceed to de-
scribe the general operation thereof, reserving for the present an ex-
planation of the winding-on apparatus.
The wires to be twisted, and in which the eyes are to be formed, are
wound as before stated upon the reels 19, and their course through the
machine is denoted by the blue line, and it is assumed that the wires
are held fast at the dies 55. Motion being now communicated to. the
shaft 8 through the medium of the pulley 2 and wheels 6, 7, the spindle
17 will by the train above described to be caused to revolve, carrying
it with the disc 20 through separate holes in which the wires pass, and
which disc is at this time pressed forward by its spring to within a
short distance of the plate 26. This revolution of the disc 20' will twist
the wires, as seen in the Diagram, upon a magnified scale, No. 1. Dur-
ing this twisting operation the spaced wheel 9 will have acted through
a portion of its teeth, but before they are all expended the sliding piece
29 will, by the operation of the tappet 47, as before described, have
descended so as to press upon the wires, and the spaced wheel still
continuing in operation will further twist the wire, but as the piece
29 rests thereon the said twisting will not be equally diffused, but will
be twisted harder beneath the said piece 29, so that a firmly twisted end
for the eye in process of formation will be obtained, as in Diagram No. 2.
When this has been accomplished the cam 48 arrives in contact with
the projecting end of the lever 38, whereby the said lever will be turned
upon its centre, and the sliding piece 35 will be drawn upward, as
before described, by the spring 36. This will bring the incline 41 to
bear against the lever 42, which, through the other lever 45, will thrust
back the disc 26, leaving a portion of the untwisted wire between itself
and the hard twisted portion; at the same time the die 83 on the sliding
piece 35 will also be carried upward, and will be thrust between the
open wires, as seen at Diagram No. 3, it being remarked that a short
space of open wires is left between the die 83 and disc 20. During the
above-mentioned operations the teeth of the spaced wheel 21 will have
communicated rotatory motion to the tube 25 through the medium of
the wheel and pinion 22, 24, and will thus have wound up the weighted
cord 28 on the pulley 27, but the operations shewn at Diagram No. 3
having been performed, the whole of the teeth of the spaced wheel 21
will have acted, and as it is no longer in gear, the weight on the cord 28
will cause the tube 25 to revolve in the contrary direction, and the wires
also will be turned in the other direction, and the consequence will be
$

page_text: that their twisting point will be between the die 83 and the disc 20,
thus producing a hard twist at the other end of the eye, as represented.
at Diagram No. 4. By this time the wheel 22 will have turned back-
ward by the force of the weighted cord 28, so as to have brought the
incline 47* under the end of the sliding piece 29, and the arm 49 over
the end of the other sliding piece 35, and the plate 26 which carries
the said sliding pieces still continuing to revolve, will by projecting
them against these inclines raise the one and depress the other, as before
described, and thus withdraw the die 83 from between the wires and
raise the piece 29 therefrom. At 55* is a guide for the wires to conduct
them to the die 55, 56, the said guide 55* being formed at the entering
end spiral, terminating in a flat tube so that the eyes turned round to
be presented flat way to the punch 54. The wires with the partly formed
eye are now drawn forward by the winding apparatus to be described,
or by ordinary means, the desired distance that is to exist between the
eyes, and the operations above described are repeated for producing
another eye,during which repetition the cam 50 forces down the punch
54, and by pressing the wire in the die 55 perfects the shape of the eye
already produced, at the same time also
eye which had
been previously made has arrived over the trough 72, and
the cam 69 causing the plunger to descend, dips the eye
into the solder therein, the said eye having in its passage
from the die 55 been prepared for the soldering process by
passing between the rollers 67, which have been brought together at the
proper time by the cam 60 acting upon them as before described. Dur-
ing the perfecting of the eye by the die 55 the punch 70 also descends
and flattens the wire at that part thereof which is to be wound in nicks
which are cut in the shafts to receive them, and thus successive eyes
are formed in the continuous lengths of wire. At 90 are two rollers,
the lower of which dips into a trough containing a japanning substance,
which is conveyed to the healds as they pass between the said rollers,
the said healds subequently passing through a box heated by gas or
other means, for the purpose of being dried. It will have been seen by
the above description that after a twisting operation, the punch 83 has
to enter between the wires, and it therefore follows that when the
spindle has revolved its proper time it must have brought the disc 20
to such a position that the said wires will be horizontally situated.
an
In order to secure this I employ the following arrangements, referring
particularly to Fig. 6, which is a partial end view of Fig. 2 upon an en-
larged scale. Upon the line shaft 8 is a cam 92 which acts against one
end of a lever 93, mounted so as to turn upon a centre at 94, and which
lever can therefore be raised or allowed to fall. Upon the axis of the

page_text: wheel 10 before mentioned is a disc 95 provided with a notch 96. When
the motion of the spindle 17 is arrested by the spaced wheel 9 ceasing
to act, the cam 92 allows a stud 97 upon the lever 93 to fall into the
notch 96 in the disc 95, and the gearing connected with the line shaft is
arrested at a definite point. In order however, to ensure an exactly
correct position of the disc 20, I apply another stop motion to the spindle
gearing. Upon the spindle 17 is a plate 98 upon which is a projecting
stud 99, above this stud is a lever 100, turning on a centre at 101 and
drawn downward at its other end by a spring 102. At the back of the
lever 100 (as seen in Fig. 6) is a stud 103, and upon the upper side is a
casing 104, which extends over the rim of the disc 98. To this casing is
connected a rod 105 guided by a slot, embracing the line shaft 8 and
carrying a pin 106 which is acted upon by a cam 107 simultaneously
with the dropping of the stud 97 into the notch 95, the cam 107 allows
the rod 105, casing 104, and lever 100 to fall, and the said casing falling
on the rim of the disc 98 acts as a break to check the revolution of the
spindle 17, and immediately afterwards the pin 99 arrives in contact
with the stud 103, which registers exactly the position of the disc 20.
In order to arrest the falling of the weight 28, and consequently the
turning backward of the tube 25, the following contrivance is adopted,
reference being had to Fig. 5. Upon the axis of the pulley 27 is a disc
200 provided with a notch 201, as seen in the detached view, Fig. 5*.
When the weighted cord 28 has turned the tube 25 the required dis-
tance, a pin 202 is thrust forward by an incline 203 on the wheel 22,
so as to intercept the notch 201, and thus the rotation of the tube is
arrested. After the incline 203 has passed from the pin 202, a spring
204 withdraws the said pin from the notch 202. Fig. 7 represents the
method I adopt for mounting the bobbins from which the wires are
drawn. The spindle 17 above referred to is shewn at 17,
upon which is a frame 110, in which the bobbins 19 are mounted; upon
this frame are jointed levers 111 drawn downward by springs 112, and
these levers therefore by pressing upon the bobbins act as breaks.
Thus far the description has referred to that part of my Invention
which consists in forming heald eyes upon continuous lengths of twisted
wire, and the healds so formed may be drawn forward as they are made
by any intermittent motion which may wind them upon a drum or other-
wise dispose them for the purpose, rewinding them upon the shafts in
a subsequent operation. But I will now proceed to describe the winding
apparatus which I have shewn connected to the above-described machine,
and which constitutes as shewn a portion thereof. Upon the line shaft
8 is a bevil pinion 112, taking into another 113, the axis of which is
provided with a spaced spur wheel 114, there being teeth on a portion

page_text: only of its circumference. This wheel 114 drives a pinion 115 mounted
upon a cross shaft 116, on which there is a bevil pinion 117 gearing into
another 118 mounted upon a shaft 119, the other end of which is pro-
vided, with a bevil pinion 120 gearing into another 121. This latter
pinion 121 is carried by the stationary framework, but imparts rotatory
motion to a shaft 122, it being mounted thereon, but by means of a
feather and slot, so that at the same time that rotatory motion is given
to the said shaft it is capable of sliding to and fro in the boss of the
pinion 121. Upon the shaft 122 is a pinion 123 gearing into a wheel
124, which is not provided with an axis, but is supported by rollers 125
running within a ring 126 formed in a fixing. The wheel 124 is pro-
vided with apertures 127 for the reception of the shafts upon which the
healds are to be wound. Upon the shaft 122 is a wheel 128 gearing into
a wheel 129 turning upon a stud which is carried by a bracket 130,
and on the other side of the machine is a similar bracket 130 which
supports the shaft -122. These brackets are united at their outward ends
by a rod 131, and at their lower ends are mounted upon a slide 132
capable of being moved in a guide 133; at 134 is a screw situate within a
nut 135, carried by the brackets 130, and driven at its other end by
means of a pinion 136 mounted upon the shaft 122, and connected to a
pinion on the said screw through the medium of a carrier 137; when there-
fore the screw 134 is caused to revolve in the fixed nut, it causes the
brackets 130 to travel in their guide 133, carrying with them the shaft
122, and gearing 128, 129, 136, 137. To the boss of the wheel 129 is
attached a plate, on the top of which is another plate 138, the two being
capable of acting as a clamp by means of nuts 139; upon the cross shaft
116 is a cam 140 acting against a rod 141, which is connected to a sliding
rod 142 mounted in guides 143. This rod is provided with a fork, with-
in which is mounted a circular saw 144 driven by a pulley 145 in con-
nexion with any convenient running shaft. As the shaft 116 therefore
revolves, the circular saw 144 is alternately pressed forward by the cam
and withdrawn by a spring 146. The operation is as follows:-The
shafts B upon which the healds are to be wound are passed through the
slits 127 in the wheel 124, as seen by the blue lines, and their ends are
confined between the clamps 138. To these shafts the ends of the wires
are conducted, and are made fast thereto. During the twisting, and
other operations above described, the cam 140 causes the circular saw
144, to advance towards and into the shaft which presents itself thereto,
the said saw being caused 'to revolve by the pulley 145, as above de-
scribed, and thus a nick will be cut in the "shaft." Motion now being
communicated to the shaft 122 through the medium of the gearing above
described, the said shaft will in its turn cause the wheel 124 to revolve,

page_text: carrying with it the heald shafts, while at the same time and at the same
speed the clamps 138 will be caused to revolve through the medium of
the gearing 128, 129, and thus the heald shafts will be carried round.
During this operation the screw 134 will come into action by means of
the gearing 136, 137, thus causing the brackets 130 to traverse in their
guides 133, and as the clamp 138 is mounted with. the said brackets, the
heald shafts will be drawn forward through the wheel 124, and the
nick above described as cut therein will lap into the manufactured
healds, which will thus be wound upon their shafts in a spiral form.
It has been described that motion is communicated to this part of the
apparatus by the spaced wheel 114, the motion of the heald shafts will
therefore be intermittent, and the teeth upon the spaced wheel 114 are
in the proper proportion to its whole circumference to cause it to im-
part a half rotation to the shafts between the formation of every eye,
thus alternately lapping the healds upon each of the two shafts, and this
in a spiral form owing to the traversing motion imparted by the screw
134, a nick by the circular saw being provided for each said half revolu-
tion of the heald shafts. In order to cause the spaced wheel 114 to
effect exactly the desired amount of rotation of the heald shafts there is
a cam 150 upon the shaft of the wheel 114 which acts against a lever
151 turning upon a centre at 152, and drawn towards the said cam by
a spring 153; when the exact amount of rotation of the shaft has taken
place, the end of the lever 151 is drawn into a notch in a disc 154 on the
shaft 116, and the spaced wheel 114 being out of gear, the motion of the
shaft 116 is arrested. In order to facilitate the drawing back of the
frame constituted by the brackets 130 and the parts connected there-
with, the nut 135 is capable, as in slide lathes, of being disconnected
from the screw 134 by means of a handle. The heald holes in the wheel
114 are prolonged as at C for the purpose of affording additional bear-
ing to the said healds, and these parts C are kept within the outward
edges of the shafts, as seen at Fig. 3, to allow the saw gates to be cut.
When the wires are wound into these nicks they are also wound upon
the supports C, and are subsequently slidden therefrom by the travers-
ing of the shafts. In order to adjust the winding apparatus to its
proper relative position to the parts which make the healds, the said
winding apparatus as a whole is rendered adjustable by being mounted
on a slide capable of adjustment by a set screw, as at D.
Having thus described and ascertained the nature of my said Inven-
tion, and the manner of carrying the same into effect, I desire it to be
understood that I claim, as secured to me under the above in part
recited Letters Patent,-

page_text: Firstly, the application of solder or other cementing material to the
eyes of healds constructed as above described.
Secondly, as applied to such healds as above described, forming the
eyes in continuous lengths of twisted wire.
Thirdly, the machinery, substantially as above described, for manu- 5
facturing, finishing, and soldering the healds.
Fourthly, the machinery for winding the healds upon the shafts.
Fifthly, the combination of machinery for making such healds as
aforesaid with machinery for winding them upon shafts.
In witness whereof, I, the said Alfred Augustus Larmuth, have
hereunto set my hand and seal, this Fifth day of August, in the
year of our Lord One thousand eight hundred and sixty-five.
