Improvements in Looms for Weaving Pile-fabrics.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
45, Southampton Buildings, London, WC, 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 pile-fabric looms, and more particularly
to the wires and the mechanism for operating them. The object of the invention
is to secure a more accurate placing of the wires in position in the shed, to prevent
their being displaced and thrown from the carriage by the sudden stoppage of
the loom due to any cause such as the breakage of a warp or filling thread, or a
mispick, to provide for the withdrawing hook being thrown temporarily out of
operation whenever desired for any purpose, and to secure certain other results
whereby the general efficiency of the loom 18 enhanced and the production thereof
increased
The means for accomplishing these various objects and ends are clearly illus
trated upon the accompanying sheet of drawings, which portray one embodiment
of the invention selected as being the best form now known to us
On the said drawings, similar letters indicate similar parts or features, as the
case may be, wherever they occur
Referring to the drawing..
Figure 1 represents a perspective view of a portion of a pile-fabric loom embody-
ing the invention
Fig 2 represents a plan view of the same.
Fig 3 represents a longitudinal section on the line 3-3 of Fig 2
Figs. 4 and 5 represent in detail a wire-head and the improved means for
securing the wire therein.
The carriage which comprises the horizontal plate a and the vertical plate at
to which the same is bolted, slides upon the guide or slide-bar a³, being reciprocated
by the arm and the connecting rod at in the ordinary way, all being of the
usual construction
Under the horizontal plate of the carriage is adjustably pivoted the withdrawing
hook b, by means of which the wires are drawn backward from the magazine
located upon the stand at the side of the loom. A spring-pressed pin & bears
against the hook to thrust it vieldingly into engagement with a wire-head, but
the action of said pin may be nullified by a cam on the end of a pivot-stud
projected through the plate a and having a milled head . The cam is concaved or
flattened so that when it is rotated to engage the hook it throws it into an in-
operative position and locks it there
The magazine c is formed with an outwardly diverging guide finger
CD
and

page_text: shorter parallel fingers co separated therefiom to permit of the entrance of the
wire-heade between them. The end of the finger is reduced to form a raised
cam surface for a purpose to be described
Heretofore it has been the practice to move the wires into operative position by
a pusher engaging the rear end of their heads, but this has in many instances
been unsatisfactory by the tendency of the pushei to raise the free end of the wire
and cause it to slide over the upper theads of the shed, or to be otherwise mis-
placed
Hence to overcome this defect, frequently seriously injurious to the fabric,-
the heads d of the wes d', which heads have the ordinary slots or apertures to
form the engaging portion on edge d³ for the hook b, is constructed with an
upwardly projecting wedge-shaped lug d, located at the front end thereof, (.e, in
fiont of the middle transverse line thereof), as best shown in Fig. 3
This lug
18 sufficiently high to project above the fingers on guides of the magazine when the
head is between them Each head is likewise provided with another stop or lug d³
near its reduced rear end, which, however, is flush with or below the cam surface o³,
when the head is in the magazine
Upon the top of the plate a of the carnage is mounted a thin metal strip e
having a reduced rear end pivoted on a stud el passed through two ears projecting
upwardly from a block. The block lies between two guide-ribs or flanges e³ on
the carriage and 18 adjustably secured in place by a nutted bolt et passed through
a slot a therein The strip is resilient, but to increase its effectiveness, an upright
threaded post 18 secured in the carriage and passed through a slot in the strip,
and a coiled spring e placed around it which bearing against nuts e on the post,
piesses downwardly against the stup. The front or fiee end of the stup is bent
downward as at es to form a hook or latch for engaging the lug d and then upward
as at e⁹ to form an abutment or stop to engage the inclined edge of the lugs d.
The strip e has sufficient rigidity to prevent the end ³ from being raised when it
18 in engagement with only the wire-head
Thus the strip performs two functions, serving, first, as a pusher to force the
wire into place, and second, as a latch to prevent the wire from being thrown
violently out of the wie-guide in case the loom be suddenly stopped In foicing
the wire through the pivoted wire-guide f, (which may be of the ordinary con-
struction) to place it in the shed, the abutment or pusher e, bearing against the
lug, tends to hold the free end of the wire downward, and prevent it from 118ing
so as to clear the warp At this time the point of the hook 18 below the upper
edge of the lug d³ and consequently, if the carriage should be suddenly stopped,
the hook would prevent the wire from continuing and would hold it against
movement When, however, the canage reaches the latter part of its forward
movement, the pusher strikes against the cam surface on the finger and 18
lifted slightly above the lug d, though not so far as to disengage it from the
lug which it continues to bear against, while the carriage completes its forward
movement to force the head into the magazine when the lug 18 flush with or
below said cam surface €5 Therefore, when the carriage commences its retro-
grade movement, and the hook b engaging the first head in the magazine, diaws it
back through the wue guide, that has in the meantime been moved into alinement
with it, the latch slides back past the other heads in the magazines without
engaging the lugs d³.
It is evident that the pusher and latch may be adjusted upon the calliage, and
that the pressure of the spring e be varied to suit any particular requirements or
conditions
In the stand underneath the magazine is formed an oil-box or tank g, as shown
by dotted lines in Fig 2, and in section in Fig 3 Through the tank projects a
shaft having thereon a brush g², partially submerged in the oil, and arranged to
engage the under edges of the wines and lubricate them, as they are withdrawn
from the fabric to cut the loops in the waip The shaft is rotated by a step-by-

page_text: step movement, being provided on its projecting end with a ratchet-wheel g³ with
which a pawl g* on a spring-retracted plunger 18 adapted to engage, and advance
one step each time the plunger is reciprocated. The plunger projects through the
stand, and 18 in alinement with the vertical plate a¹ of the carriage extending
into position to be engaged by the latter at the extremity of its forward movement
The lubrication of the wires renders it easier to withdraw them from the fabric,
as 18 obvious.
Novel means for affixing the wires in their heads d are also provided The
heads are slotted in their bottom edges, the slots being adequate to receive the
wires, though deep enough to cause the flanges to project beyond the wires.
After a wire is placed in the slot in a head, the flanges are upset or forced inward
so as to tightly bind the wire between them, the flanges being assisted by the
bend or head on the end of the wire.
By examining the mechanism herein before described, in connection with the
results, stated in the first part of this specification it was desued to obtain, it will
be seen that the objects of the invention are all reached by the employment of
devices in themselves simple in construction and easy to repair or replace
