IMPROVED MACHINERY OR APPARATUS FOR "SLAYING WARPS."
"
This Invention relates to new or improved machinery or apparatus for "slaying
warps or drawing the threads or ends through the reed before placing the same
in the loom.
The apparatus consists of a frame for supporting the warp and the reed, the latter
being nearly horizontal so that the ends of the warp can rest thereon. Under the
reed is a shaft carrying three hooks for pulling the ends through the dents of the
reed similar to those used when the operation is performed by hand, the boss to
which the hooks are attached sliding on a feather on the shaft which is caused
to revolve by means of a ratchet wheel and pawl operated by lever and treddle.
By means of a triangular tappit fixed on the end thereof, this shaft communicates
intermittent motion to a screw shaft placed below it, on which is fitted a boss
terminating in a fork or clutch. At each motion of the treadle the upper shaft is
moved round a third of a revolution, and as the hooks project above the face of the
reed, the operator places an "end" in contact there with, and on the next movement
of the shaft the thread is drawn through the reed and another needle rises in the
next dent, the necessary lateral traverse being given to the needles by the fork on
the screw shaft the extent of such traverse being regulated by using change
ratchet wheels and tappits.
In order that our Invention may be more fully understood we herein give
reference to the accompanying Sheets of Drawings, illustrative thereof.
Fig. 1
and Fig. 2 are end views of the machine Fig. 3 a front elevation thereof and Fig. 4
a plan. A is the reed which is carried by the framework B, the warp beam being
supported by the rack C from which the end of the warp hangs and rests upon the
reed. On a shaft D is mounted a sliding boss E which carries three hooks F and is
moved laterally by the fork G attached to the hollow screw H which is mounted
on the screw shaft J. On one end of the shaft D is a three toothed ratchet wheel K
operated by levers and pawl L and treddle M each motion of the latter causing
the shaft D to turn round one third of a revolution. On the other end of the
shaft D is a tappit plate N, which by acting on the levers O and ratchet wheel P
communicates rotary motion to the screw shaft J, and so produces the requisite
lateral traverse of the hooks F. In order to accommodate the extent of the lateral
motion to the various pitches of reed the shape of the tappit N may be altered so
as to give a greater or less amount of motion to the levers O. Fig. 5 is a detail
of reed and hooks F with the parts connected therewith. Figa 6 and 7 are front
and end elevations of a machine of which the operation is similar to the one above
described, but in which the shafts D and J are caused to revolve by a train of
toothed wheels which may be changed when it is desirable to alter the relative
speed of the two shafts.
The motion of the treddle causes the catch rod Q to engage with one of a series
of pins on the face of the wheel 1 causing it to revolve partially and turn round
the pinion 2 on the end of the shaft D one third of a revolution. The motion of
the first wheel is communicated to the remainder of the train 3, 4, and 5 the latter
of which is mounted on the screw shaft J.
In Fig▪ 8, 9, 10, 11, and 12 we have shewn a modification of the machine by

page_text: which the screw shaft may be dispensed with. In this case we only employ one
hook F which forms a continuation of a worm R formed on the boss E. The pitch
of this worm corresponds with that of the reed, between the dents of which it
enters as shewn in Fig. 10. On the end of the shaft D are two catch wheels S each
having a catch a one of which is pivotted to the frame of the machine, and the
other to the face of a loose pulley T around which passes a belt U, one end of
which is attached to a spring V and the other to the treddle. At each motion of
the treddle the pulley is turned completely round and carries along with it the
wheels S and shaft D. As the treddle rises the spring V reverses the direction of
the pulley which returns to its original position, the shaft being prevented from
following it by means of the catch S fixed to the frame. In order to remove all
strain upon the dents of the reed the shaft D may be made hollow, so as to admit
the sliding plug a to which the boss E may be attached by means of the screw c
which passes through a longitudinal slot in the shaft. A weight can then be
attached to the plug by means of cord and swivel which will counteract any
tendency of the boss to bind on the surface of the shaft D (see Fig. 11).
The worm R may be formed of washers stamped out of thin metal and secured
into spiral grooves formed around the boss E, the washers being cut at one portion
of their circumference so that the adjacent ends may be fastened together.
Having thus described the nature of our Invention, and the manner in which the
same may be performed, we would have it understood that we do not confine
ourselves to the precise details of construction herein shewn and described, as from
the examples given it will be seen that they admit of much variation, but what we
claim as our Invention, and consider to be new is-
The construction and use of a machine for "slaying warps" in which are
employed one or more hooks F mounted upon a shaft D and having a revolving
and lateral motion communicated to them by any of the means herein indicated, or
any mere modification thereof.
In witness whereof we the said Richard Longden Hattersley and William
Greenwood have hereunto set our hands and seals this Tenth day of May, in
the year of our Lord, one thousand eight hundred and eighty three.
