Improvements in and relating to Stopping-mechanisms of
Looms for Weaving.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45, 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 has relation generally to looms for weaving plush and other
similar pile fabrics," and more particularly to the stopping mechanisms there-
for, having for its object to provide certain improvements therein whereby the
loom may be stopped manually or automatically to meet certain conditions and
requirements.
The invention consists in a loom possessing certain features of construction
and relative arrangement of parts, all as fully illustrated upon the drawings,
now to be described in detail, and finally pointed out in the claims hereunto
appended.
Reference is to be had to the accompanying drawings, and to the letters and
figures marked thereon, forming a part of this specification, the same letters
designating the same parts or features, as the case may be, wherever they occur.
Figure 2 represents a front elevation of the same, parts being broken away.
Figure 3 represents a section, taken through the slide or bunter.
Figure 4 represents a perspective view of the connections between the various
stopping mechanisms.
Referring to the said drawings, the standard a, the lay b, the swords 61,
the take-up c, and the magazine d, are all of the ordinary construction. The
Jay carries the usual dagger 2 which in case of a mispick is allowed to drop to
engage a shoulder 3 on a slide or bunter 6 on the support 65. The rear end
of the bunter bears against a block 66 of rubber which cushions it to prevent
jarring of the loom.
Extending across the front of the loom is a rock-shaft f encircled by a spring fl
which normally holds it yieldingly against movement. Secured to the end of
this shaft furthest from the magazine is an upright arm f terminating in a
handle f, and provided with a fug f to receive the thrust of the filling-stop
stide The filling stop-motion which comprises a fork and its co-acting parts
is not shown, as they are familiar to those skilled in the art to which this
invention relates.
On its other end the shaft is provided with a two-armed lever g, one of its
arms projecting forwardly, as shown in Fig. 3, and terminating in a handle,
and the other shorter arm being cylindrical and projecting downwardly into
an eye swiveled in the end of one arm of a two-armed lever, secured upon a

page_text: vertical rock shaft 2. One arm of said lever is arranged perpendicularly to
said arm and carries said eye while the other 3 is pivoted to a connecting
rod having its free end slotted as at 5 to receive a stud 67 projecting laterally
from the bunter or slide 4. There is a head on the stud 67, as shown in Fig. 4,
to prevent its being disengaged from the slotted end of the connecting rod h.
the actua-
By this arrangement, it will be seen that the rocking of the shaft for.
tion of the bunter will cause the vertical shaft 2 to rock also.
Secured to said shaft he is an arm or latch i, the hook or stop of which is
adapted to engage the shipper-lever ; which is fulcrumed at j¹. This lever is
provided with a pivoted handle having a finger 3 adapted to move past the
edge of the reduced portion thereof, the parts being so arranged that when
the shipper lever is swung in the direction of the arrow in Fig. 4 to start the
loom, the hook engages the edge of the said reduced portion . In order,
therefore, to disengage the lever from the hook, the handle 2 is pushed rear-
wardly and its finger ³ engages the end of said hook and thrusts it out of engage-
ment with the said lever, the usual spring forcing the shipper lever into position
to disengage the clutch members on the power shaft and stop the loom.
The loom may also be stopped manually by means of the handles for g¹, one
at each side of the loom, so as to be quickly grasped by the operative in what-
ever position he may be with relation to the loom. The said handles f³ gl are
drawn forward to rock the shipper-lever f which in turn swings the stud g²
rearwardly, thereby rocking the shaft h2 and throwing the hook out of engage-
ment with the shipper lever.
The warp stop-motion (not shown) may be likewise connected with the devices
previously described whereby it will be seen that in case of a mispick, the failure
or breakage of a filling thread, or the breakage of a warp thread, the loom will
be automatically stopped.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, as communicated
to me by my foreign correspondents, I declare that what I claim is :-
1. In a loom, the combination of a latch, and a shipper lever adapted to be
engaged thereby, said lever being provided with movable means additional to
the part which engages said hook or latch for disengaging the hook therefrom.
2. In a loom, the combination with a movable hook or latch, of a shipper
lever adapted to be engaged thereby, said lever being provided with movable
means for forcing said hook or latch out of engagement with said lever.
3. In a loom, the combination with a hook or latch, or a shipper lever adapted
to be engaged thereby, and a handle pivoted on said lever and having a finger
to disengage said hook or latch therefrom.
4. In a loom, the combination with a hook or latch, a shipper lever adapted to
be engaged by said hook or latch, a stop-motion adapted to disengage said latch
from said lever, and a handle pivoted on said lever for disengaging said latch
from said lever.
5. In a loom, the combination of a rock-shaft, a filling stop-motion adapted to
rock said shaft, a second rock-shaft transverse to the first-mentioned shaft, and
operatively connected thereto, a latch connected to said second shaft, and a
shipper lever adapted to be held in operative position by said latch.
6. In a loom, the combination of a shipper lever, a latch for said lever, a
rock-shaft on which said latch is mounted, a second rock-shaft, a filling stop-
motion mechanism arranged to rock the last-mentioned shaft, mechanism
actuated by reason of the failure of a shuttle to reach its box, connections between
the last-mentioned mechanism and the said first rock-shaft, and connections
between said second rock-shaft and said first rock-shaft.
7. In a loom, the combination of a shipper lever, a rock-shaft having a latch
to engage said lever and also having an arm, a cross-shaft provided with an arm

page_text: engaging the first-mentioned arm to rock the rock-shaft and disengage the latch
from the shipper lever, and a handle on said cross-shaft.
8. In a loom, the combination of a shipper-lever, a rock-shaft having a latch
to engage said lever and also having an arm, a cross-shaft provided with a two-
armed lever, one arm engaging said arm, and the other constituting a handle,
and a spring for holding said latch in engagement with said shipper lever.
