We JOSEPH HORROCKS and EDWIN HORROCKS of Osborne Street, Bradford in
the County of York Picker Manufacturers, do hereby declare the nature of our
invention for IMPROVEMENTS IN THE PICKING MOTION OF LOOMS FOR WEAVING
to be as follows:-
This invention relates to picking motion of looms for weaving and consists of
novel arrangements or devices for actuating the shuttle, whereby the ordinary
picking motion is in a great measure dispensed with.
Our improvements consists of a picking lever attached by its its lower end to the
loom frame, or to the swing rail of the going part, in such a manner that the top
end of the said lever, which passes up through a slot into the shuttle box and is
there attached to the picker, is free to move with the going part of the loom and
also longitudinally in the said slot formed along the under side of the shuttle box.
A wheel which is preferably keyed on the tappet shaft, but may be mounted on
a separate stud or shaft and inay be driven in any convenient manner, is formed
with a cam or projection on its face. The said cam or projection at each revolution
of the wheel on the tappet shaft engages with and depresses one end of a lever,
mounted at or near its centre on a stud or brackit attached to the loom frame, the
other end of the said lever carries an antefriction roller which bears against the
herein before mentioned picking lever. When a pick is required to be made
the parts are so relatively arranged that the cam projecting from the face of the
wheel on the tappet shaft engages with and depresses the end of the said lever,
thus, the antifriction roller carried by the other end of such lever bears against
the picking lever and forces the free end of such picking lever, and the picker
attached thereto, towards the centre of the loom and thereby impels the shuttle
across the loom.
The above arrangement may be modified by working the picking lever direct
from the cam or projection on the face of the wheel on the tappet shaft. In which
case we employ a horizontal or nearly horizontal picking lever attached to the
frame of the loom, one end of which lever passes through slots in the shuttle box
and the picker slides thereon so as not to interfere with the going part. The cam
or projection on the face of the wheel on the tappet shaft imparts the requisite .
motion to such lever to impel the shuttle across the loour.

page_text: By employing an arrangement similar to either of those above described in
connection with the shuttle box at the other end of the loom and working the two
arrangements consecutively the shuttle will be continuously impelled from one
shuttle box to the other.
The herein before mentioned cam or projection is preferably formed at one end of
the loom on the wheel for driving the tappet shaft. And the wheel formed with
the cam or projection at the other end may be replaced by an arm fixed to the
tappet shaft. In any case such cams or projections and the ends of the levers with
which they engage are so formed that when the loom is worked backwards the
picking levers are not actuated.
Springs are used to restore the picking levers to their original position after
making a pick...
We employ pickers of metal or other suitable material which work in guides
formed in the shuttle box,

We JOSEPH HORROCKS, and EDWIN HORROCKS, of Osborne Street, Bradford, in
the County of York, Picker Manufacturers, do hereby declare the nature of this
invention for IMPROVEMENTS IN THE PICKING MOTION OF LOOMS FOR WEAVING
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 the picking motion of looms for
weaving, and it consists of novel combinations or arrangements of mechanism for
actuating the shuttle.
The said arrangements consist of a picking lever pivotted to the loom frame or
to the swing rail of the going part in such a manner that the top end of the said
lever, which passes up through a slot in the shuttle box and is there attached to
the picker is free to move with the going part of the loom and also longitudinally
in the said slot formed along the underside of the shuttle box. A wheel which is
preferably keyed on the tappet shaft but may be mounted on a separate stud or
shaft and driven in any convenient manner is provided with an antifriction roller
or other suitable projection on its face. The said antifriction roller or projection
at each revolution of the tappet shaft is arranged to engage with and actuate one
end of a lever mounted at or near its centre on a bracket or stud attached to the
loom frame, the other end of the said lever carries an antifriction roller which
bears against the hereinbefore mentioned picking lever or against an antifriction
roller mounted thereon.
When a pick is required to be made the parts are so relatively arranged that the
antifriction roller or projection on the face of the wheel secured to or actuated by
the tappet shaft engages with the end of the said lever thereby causing the other
end of such lever upon which an antifriction roller is mounted to bear against the
picking lever and force the free end of such lever and the picker attached thereto
towards the centre of the loom and thereby impel the shuttle across the loom.
By employing an arrangement similar to that above described in connection with
the shuttle box at the other end of the loom and operating the two arrangements
consecutively the shuttle will be continuously impelled from one shuttle box to the
other.
The bereinbefore mentioned antifriction roller or other projection engaging with
the lever which operates the picking lever is preferably mounted at one end on the
wheel for driving the tappet shaft. The said antifriction roller or projection at
the other end of the loom may be mounted on a similar wheel, or an arm fixed on.
the tappet shaft may be used for this purpose. In any case such projections
and the end of the levers with which they engage are so arranged that when the
loom is turned back wards the picking levers are not actuated.
Springs are employed to restore the picking levers to their original position after:
making a pick.
We employ metal or other suitable material from which to form the pickers
which are arranged to work in guides formed in the shuttle box.

page_text: Reference is to be had to the accompanying drawing forming part of this
specification in which similar letters of reference indicate corresponding parts in
all the figures.
Figure 1 represents a front elevation of such parts of a loom as are necessary to
illustrate our invention in which for greater perspicuity the front framework is
omitted the broken line 1, 2 in the second figure indicates the line of section.
Figure 2 represents an end elevation of the same.
Figure 3 is a front elevation similar to Figure 1, in which a modified form of
picking mechanism is illustrated. Figure 4 is an end view of the same.
Figures 5, 6, and 7 are views of details hereinafter referred to. Figure 8 is a
plan, Figure 9 a front view and Figure 10 an end view of the picker employed.
Referring to Figures 1 and 2: The antifriction roller A is mounted on a stud
secured in the slot formed in the face of the wheel B driving the tappet shaft C.
The said antifriction roller engages with the curved end of the lever D, mounted on
the stud F fixed to the loom frame, at each revolution of the shaft C and
depresses the opposite end of such lever carrying the antifriction roller E. The
picking lever H is mounted on a stud fixed in the slot I formed in the bracket J,
secured on the end of the swing rail K, and its upper extremity passes through a
slot made along the underside of the shuttle box L where it is connected to the
picker M. The said picking lever is provided with a short arm N carrying the
antifriction roller N¹ upon which the antifriction roller E bears and each time the
roller A engages with the lever D the arm N of the picking lever is depressed, thus
causing the extremity of such lever to which the picker M is connected to be
rapidly driven along the shuttle box thereby driving the shuttle from such shuttle
box into the shuttle box at the other end of the lathe. The spring O stretching
from the loom frame G to the arm P projecting from the picking lever H restores
the parts to their normal position after the shuttle has been impelled.
It is obvious that a similar arrangement of picking mechanism in operation at
the other end of the loom will return the shuttle, and the two arrangements
working rhythmically will continuously impel the shuttle from one shuttle box to
the other.
A stop or buffer R against which the top of the picking lever H rests is provided
to deaden the concussion caused by the shuttle striking the picker when it enters
the shuttle box, and a suitable stop or buffer is also fitted at the inner end of the
slot in the underside of the shuttle box to stop the picking lever after the shuttle
has been impelled.
In the modified form of the picking mechanism shown in Figure 3 and 4,
a lever D¹ is used instead of the lever D. The lever D¹ is mounted in bearings
formed in the bracket W a plan of which is represented by Figure 5.
The projection A¹ secured in the slot formed in the face of the wheel B is adapted
to engage with the arm U of the lever D¹ each time the wheel B makes a revo-
lution, thus the said arm is actuated and a corresponding motion thereby imparted
to the arm V carrying the antifriction roller E¹ which bears against the picking
lever H and thereby communicates the requisite motion to such lever to impel the
shuttle:
The method of adapting the picking lever to a circular shuttle box is shown in
Figure 6 which represents an end view of a circular shuttle box the bracket
supporting it being shown in section. Figure 7 is a back view of the same.
The picking lever H instead of passing through a slot in the bottom of the
shuttle box is curved round the back and over the the top of the box, and passes
through the hole C¹ in the picker M¹ which picker is mounted on the spindle F¹
fitted over the shuttle box.
The picker employed by us in connection with the herein before mentioned picking
mechanism is made of hide, metal, or other suitable material and is illustrated on a
larger scale in Figures 8, 9, and 10.
The end of the picking lever passes through the hole C which connects it to
the picker. The said picker is guided in its traverse along the shuttle box by the

page_text: projection B' on the front face and the projection H¹ on the back thereof. The
projection B¹ fits in the horizontal slide J1 formed in the front side of the shuttle
box and the projection H fits against the back of the shuttle box. The feet J*
provided on the bottom of the picker, slide in the slot formed along the bottom of
the shuttle box and assist in guiding such picker.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare what we
claim is:
1. In a loom for weaving, the combination and arrangement of mechanism for
operating the picking lever, consisting of a lever pivotted to the loom frame and
operated by an antifriction roller or other projection mounted on the tappet shaft,
the said lever being provided with an antifriction roller adapted to engage with
the picking lever or an antifriction roller mounted thereon and actuate such lever,
substantially as herein shown and described.
2. In a loom for weaving, a picker formed substantially as herein shown and
described, that is having a projection on the front face adapted to slide in a guide
in the front of the shuttle box, and also a projection on the back to fit against the
back of the shuttle box.
