COMPLETE SPECIFICATION filed by the said George Haseltine at the
Office of the Commissioners of Patents, with his Petition and
Declaration, on the 1st July 1874, pursuant to the 9th Section of
the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
HASELTINE, of the "International Patent Office," Southampton Build-
ings, London, Doctor of Laws, send greeting.
WHEREAS I am in possession of an Invention for "An IMPROVED
MACHINE FOR MAKING WEAVERS' HARNESS," and have petitioned Her Majesty
to grant unto me, my executors, administrators, and assigns, Her Royal

page_text: Letters Patent for the same, and have mado solemn Declaration that
it has been communicated to me from abroad by The Kendrick Loom
Harness Company, Incorporated, of Providence, Rhode Island, United
States of America.
NOW KNOW YE, that I, the said George Haseltine, do hereby declaro 5
that the following Complete Specification under my hand and scal, fully
describes and ascertains the nature of the said Invention, and in what
manner the same is to bo performed in and by the following statement,
reference being had to the accompanying Drawing forming a part of this
Specification:-
1
The object of this Invention is to produce a machine which shall
automatically make that description of loom harness in which the eyes
are formed by clasping two metallic bands at the requisite distance apart
around the two contiguous twines which constitute the respective heddles
of the harness as distinguished from those descriptions of loom harness 1
wherein twines which constitute the heddles are knotted or otherwise
concatenated to form the eyes.
The said machine comprehends devices for laying two twines alternately
across from side band to side band of the harness in successive con-
volutions, and also in combination therewith devices for supplying the 2
machine with wires suitable for the two clasps for each heddle; for
cutting off the same into suitable lengths to form the clasps; for partially
shaping the same; for inserting the heddle twines in the partially formed
clasps, and for finally closing the clasps firmly upon the heddles.
A special means peculiar to the machine is exhibited for selecting the 2
leash of the harness.
In connection with the aforesaid devices for performing the above-
named operations I also employ means which are common to other
harness making machines for crocheting the several heddles to the

page_text: Figure 6 exhibits a heddle eye.
A represents a base plate or platform, to which are suitably secured the
columns B, B; B, B, at their top ends attached to the circular plate D,
Figure 2. These two plates A and B are used for supporting the operating
mechanism of the machine.
The two twincs m, m³, to form the heddle are carried by two spools
n, n, mounted on two spool stands o, o¹, which are constructed in any
convenient form that will allow the twines to be given off from the
spools.
The spool stands o, o', are attached to the top of a crown gear wheel E,
which revolves around the circular plate D. Motion is imparted to the
crown gear wheel E by a gear wheel F on the primary shaft G, which is
supported in the bearings H, H, and receives motion from any competent
primo mover.
Tho two twines f, f, for binding or securing the heddles as they aro
successively formed to the bands are carried by two spools p, p, mounted
on spool stands q, q, which are rovolved around studs i, i, once during
the formation of cach heddle by means of the bevel gear wheels
engaging with the bevel pinions,, attached to the shaft I, which
in turn is connected by gear wheels J, J, to the primary shaft G.
The two bands 7, 11, Figure 1, of the harness are taken from spools, and
led thence under friction pressure springs through hollow vertical studs
,, and finally made fast to a sliding bar above the machine adapted to
slide on a vertical standard in a manner similar to that described in the
Specification of Letters Patent granted January 2nd, A.D. 1855, to
Joseph S. Winsor. In the present instance, to avoid confusion in
the Drawings, the spools for the bands are not shewn, neither is tho
sliding bar for the side bands represented. As the heddles are formed
in succession and secured to the bands they are to be supposed to bo
drawn upward by the upward movement of the bar to which the bands
aró secured, and over the ends of the two rods S, S¹, Figure 1, whose
offices are to preserve tho leesc of the harness. These two rods S, S¹, are
located in the central vertical plane of the machine with their upper
ends attached to an adjustable arm. The lower end of the rod s is

page_text: pointed, and has its point situated in the horizontal plane and at the
right of the top of the stud i. The lower end of the rod s¹ is situated
below the horizontal plane and at the left of the top of stud i¹.
c, c', Figure 2, represents two pincers of gripping fingers located ono at
the right and the other at the left of the table K, whose offices aro to
draw the heddle twines down into the rudimentary heddle clasps, herein-
after to be described, and there hold them until the operation of closing
the said heddle clasps around the heddle twines is accomplished. These
pincers have an intermittently vertically reciprocating movement given
to them by means of the cams L, L, Figuro 1, secured to the shaft I. The 1
return movement of the said pincers c, c¹, is effected by the recoil of
spiral springs 2, 21.
In addition to the intermittent reciprocating movement given to the
pincer c it also receives an oscillatory movement, which causes the
heddles as they are successively finished to be disposed alternately upon 1
each side of the rod S. This movement is effected by th ecam L', Figure 1,
actuating the lever I attached to the stock which holds the nipper c,
and thus is produced what is known as the "lcash" in the harness.
The two wires d², &, to form the clasps at the ends of the eyes of the
heddles are carried by two spools Z, Z, Figure 1, mounted on a horizontal 2
rod whose ends are supported in the standards Z, Z'.
Z, Z, represents a pair of rolls for feeding the wires &, d', to the
cutters, and which have an intermittently rotary movement communi-
cated to them by means of a ratchet 3 pivoted to the bar 4, which latter
is connected to lever 5, Figure 1, bearing on the cam M, which is secured.2
to the shaft L.
K represents a former having its lower edge convex, and which in
connection with a corresponding concave die made in the end of the
vertical wire cutter a serves the purpose of shaping the wire blanks for
the heddle clasps into the form of a semicircle. The said former K is 3
on the end of and at right angles to the vertical bar h arranged in the
central vertical plane of the machine, and which bar is actuated vertically
and horizontally by means of the cam W, Figure 1, in combination with
two spiral springs arranged at right angles to each other, one of which
is shewn at , Figure 3. The cutter x is arranged in the vertical centre 3
of the machine, and has vertically intermittent movement communicated
to it by means of a cam-shape flange attached to the cam M.

page_text: C
V, Figures 3 and 4, represents a stationary wire holder and guide for
guiding and holding the wire in the proper place while being cut off by
the wire cutter .
.
N, N, are slides arranged in guides on top of the table K and at right
angles to a vertical plane through the studs i, i. The inside ends of the
slides N, N, Figure 2, are respectively provided with sets of dies a, a,
and a', a', the offices which the said dies perform being first that of
holding the rudimentary heddle clasps during the operation of having
the hėddle twines placed into them, and second, that of closing the said
clasps around the heddle twines. The slides N, N, with their respective
sets of dies have an intermitting reciprocating movement communicated
to them by means of the cams t, t, Figure 1, and lovers 1,72
The arm to which the side bands are to be attached having been
moved to a position just above the plane where the heddles are formed
the bands 1º, »º¹ª, are drawn off their spools under pressure springs through
studs i, i¹, and thence to the said arm. The heddle twine m and binding
twine fare drawn from their respective spools and fastened to the band v.
The heddle twine m² and binding twine f¹ are also drawn from their
respective spools and fastened to the band . The wire for forming the
heddle clasps is drawn from the spools,, and up between the feed
rolls, and thence through table K to and through the guide and
holder to the cutter x. The rollers v³, v³, now feed the wires d³, d³,
through the guide and holder V so that they project from the said holder
the required length for the heddle clasps. The former & then takes a
position directly over and nearly in contact with the projecting wires.
The cutter 4 next moves upward, and having partially cut off the pro-
jecting wire it brings them into contact with the former %, which in
combination with the cutter 4 in its continued cutting movement crimps
the wires into the form of semicircles. These wires are now ready to
receive the heddle twines, as shown in Figure 3. a, a, a, a', then move
simultaneously up to the rudimentary clasps and hold them in tho
position shown at Figures 4 and 5. During this operation the nippers
c¹, c³, are made to rise and take hold of the heddle twines m, m³, which
have been given off from the spools u, u¹, as the latter were revolved
with the crown gear wheel E has mado half a complete revolution,
so that at this movement the said twines are in close contact throughout
their extent across the machine, and cach twine is in contact with the
opposite band to which it was last attached. The nippers now draw the

page_text: two twines m, m², constituting one heddle, into the partly formed clasps,
as shown at Figure 4. Then the dics a, a, a, a, simultaneously continue
the motion which brought them in position to hold the rudimentary
clasps, and close the said rudimentary clasps around the heddle twines
m, m³, as shown in Figure 5.
The next oporation of the machino is to secure the heddlo twines as
they continue to be held by the nippers to the bonds », ³, by means of
the binding twines f,f. This object is accomplished in the same manner
as that shown in tho former Letters Patent granted to me for “Im-
provements in Harness Machines." This last operation of securing the
heddlo twines completes the construction of the heddlo, which is still
held by the nippers c, c¹. The nipper c is then made to oscillate either
to the front or rear of the rod S, after which the two nippers release the
heddle. This operation will cause the two twines forming each heddle
to be deposited at one end on one side of the corresponding rod S, and
at the other end on each side of the other rod S¹.
The heddles as they are formed aro taken out of the plane whercin
they are formed by the upward movement of the sliding bar to which
the bands, r, are attached. This upward movement is effected by a
sliding bar.
Having thus described the nature of the said Invention as communi-
cated to me by my foreign correspondent, and the manner of porforming
the same, I wish it understood that I do not limit myself to the precise
construction and arrangement of the several devices, but I include all
variation of form and arrangement which will perform the same:
operation by equivalent means, and I claim,-
First. In combination with the revolving annulus E furnished with
the spood stands o, o¹, spools u, u³, for carrying the heddle twines, with
suitable devices, as described, for crocheting or otherwise attaching the
heddles to the side bands of the harness, whereby the twines to form the
heddles of tho harness aro laid in regular successive convolutious, as
herein specified.
Second. In combination with suitable heddle-forming mechanism the
feeding rollers 2, 3, the cutter 4, the crimper k, and the holders and
dies a, a, the same being respectively for feeding forward the wires to
form the clasps for cutting the same into proper lengths, for crimping
the wires to cut them into rudimentary clasps, for holding the latter

page_text: while the heddle twines are inserted, and finally for closing the clasps
the twines, as herein set forth.
upon
Third. The crimping bar h, k, arranged to move in vertical and hori-
zontal planes,-in combination- with a vertically moving cutter X for
crimping the wires into shape, to secure the heddle twines, and then
retreating out of the path of the devices subsequently employed to
insert the heddle twines in the partially formed clasps, and close the
latter upon the twines, as herein described.
.
