Improvements in Machines for Making Heddles or Harness for
Looms.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co. Patent Agents,
Southampton Buildings, in the County of Middlesex, 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 particularly relates to. Machines that will automatically carry the
continuous links of fine annealed wire (constituting and forming the lashes of the
solid eyes in a leaf of Heddles or Harness for Looms) over the bars or staves, and
uniformly arrange the same upon the pads or ropes in the outer grooved edges of the
said staves so that the eyes will be held at equal distances from the same on a right
line, by means of two continuous strands of wire, alternately threaded through the
small holes at each end of the said eyes, to be looped over the bars or staves by the said
machine.
In order that the Public may fully understand the nature of my Invention, and
those who are skilled in the mechanic arts may be enabled to construct, arrange,
and operate the several parts of my improved machine, I will describe it as follows,
to wit:-

the base of the supporting hooks at Sthe top or actuating lever is shown at N¹.
Figure 12 is a perspective drawing of the case gg containing the separating
or dividing hooks with the bottom portion of the separating hooks which is
thrown upward by the action of the projection 9 on the lever q' and carried by the
action of the lever f. (which is shown in dotted lines) in its upward motion, to
operate upon the points ¹¹. The compensating spring 4 is employed to draw back
the hook. The connecting rod gl connects the cam Q to the lever gl. The loose
ends of the wire lashes W' after being passed through the eyes are fastened to the

page_text: carrier C, to prevent the said wire lashes from being drawn out of the eyes by the
action of the looping hooks when drawing the wire loops to the heddle bar B.
After the leaf or heddles is completed these wire strands are detached from the
carrier and finally secured to the end of the bars B in the manner and for the
purpose set forth.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed as communicated to me
by my foreign correspondent I declare that what I claim is
First. A machine having horizontal gearing G G arranged as shown and
described in combination with the slotted crank movement E and D, operating by
means of bevel gearing Gunderneath the same; the whole operating in conjunction
with the cam Q by means of the driving pulley P, in the manner and for the purpose
set forth.
Second. What is claimed in heddle machines is, the straight metallic strip Z
to receive the solid eyes (arranged edgewise) and hold the same on a right line upon
the bed or ways u, with a follower S to keep the eyes in an upright position upon
their edges, to receive the wire strands W₁, W₁ (from the spools S, S) through the
small holes at each end of the eyes.
Third. What is claimed in heddle machines is, the downward soparating points X
with the space X in the case K in conjunction with the upward dividing hooks
or points X, to separate the eyes upon the strip Z and carry them back so as to leave
a space sufficiently wide to allow the hook h¹ to take up the wire strand and carry it
out to the longitudinal traversing hook h, which, in its turn carries the wire lash W
over the bar B and carrying rope or pad o in the groove on the outer edge of
the heddle bar, also the pressure spring b, b which presses the wires W down upon
the end of the bar B. as it leaves the hook h.; all constructed, arranged, and operating
in the manner and for the purpose set forth.
Fourth. What is claimed in Heddles or Harness Machines is, the longitudinal
reciprocating box S S provided with hook h., the whole operating by means of
a cam movement arranged underneath of said box, in combination with the spring Vi
operating in Scam y. and lever V₁ all constructed, arranged, and operating
substantially as above set forth.
Fifth. What is claimed in a Heddle Machine is, the ropes or pads o¹ operating in
the grooves upon the outer edges of the shafts or Bars B., so as to receive and hold the
lashes or loops Wi Wi when placed upon the same by the hooks h. in a uniform
manner, to hold the eyes equally distant apart between said bars, in the manner and
for the purpose set forth.
Sixth. What is claimed in Heddle Machines is, the hooks X1 X¹ operating in the
case g. and levers q. q to give an upward movement to the dividing hooks X¹,
preparatory to the levers f. giving the outward movement to the dividing
hooks X¹¹.
Seventh. What is claimed as a further Improvement in Heddle Machines is, the
case g., lever, projection q. (in dotted lines) on the lever q¹, pin q, spring 4.,
connecting rod that connects the lever q¹ to the cam Q., in combination with the
dividing hook XX¹ with forked bottom a., ways u., as shown at Fig. 12.; the
