1, SAMUEL WALKEY GILLETT, of 17 St. Ann's Square, Manchester, in the
County of Lancaster, Registered Patent Agent, do hereby declare the nature of
this invention, which has been communicated to me by Carpet Loom Company a
corporation organized under the laws of the State of Massachusetts, of Brussels
Street, Worcester, State of Massachusetts, United States of America, Manu-
facturers, 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 a means for controlling the weft threads in a loom in
which the weft is inserted in the form of a loop, such, for example, as is done in the
needle looms used for weaving Moquette carpets.
The invention consists in providing a loom of this character with a stationary
weft-horn and with mechanism for lifting the weft off of the horn and for replacing
the weft around the horn at the proper times.
In looms of the character to which this invention relates, it is desirable and
necessary to prevent the loop of the weft from pulling on the edge or selvage of
the shed or warp threads while the weft is being inserted into the shed, and to allow
the weft to be pulled tightly up against the edge of the shed or warp after the weft
has been carried through the shed.
The accompanying sheet of drawings shows only the detached mechanisms of the
loom that are necessary to carry out this invention.
Referring to the drawing,
Fig. 1 is a side elevation of the parts of the loom to which this invention is
applied,
Fig. 2 is a plan view of part of the same, and
Fig. 3 is an isometric view of the weft controlling mechanism.
Referring to the drawing and in detail, 100 designates the usual breast-beam,
101 the usual oscillating lay, and 102 one of the power-shafts of a loom of the
character referred to.
103 designates a bracket which is rigidly secured to the loom-frame in any desired
manner.
This bracket has an extending arm 105 which carries a stud, on which stud is
journalled a bell-crank lever 106, which part may be termed the "detacher."
Secured in the ordinary bracket 105 is a piu or horn 104 which may be called the
"weft-horn."
The detacher 106 is normally kept in one position by means of a spring 107.
Connected to the lower end of the detacher 106 is a rod or link 108, which extends
to the rear of the loom, and has a slotted end, as shown.
Engaging the slotted end of this link 108 is a piu carried by a rocking lever 109
which is carried by a stud or shaft 110.
This lever 109 carries a roller 119 which bears on the face of a cam 111 secured
on the shaft 102.
The cam 111 has a number of projections 112, as shown, which are so arranged
that at the proper time the lever 109 will be moved to the right, and the upper end
of the detacher 106, by the connections previously described, thereby lifted.
A piece of wire 113 is rigidly secured to the bracket 103, and is bent, as shown.
The upper end of the detacher 106 is provided with a recess 114, and the end of
the same is pointed, as shown, so that a guide-way will be formed between the
Price 8d1

called a retainer.
Any of the usual forms of weft-carriers or inserters may be used.
Fig. 3 shows the usual needle 117 commonly used for this purpose.
Mounted on the end of the lay 101 is a suitable bracket to which is secured a
part 115 which may be termed the "guide," and also secured to said bracket is a
cam 116.
The guide 115 and the cam 116 may be adjusted on the bracket so as to properly
operate.
The weft thread is designated by the numeral 118.
The operation of the mechanism is as follows:-
In Fig. 3 the weft 118 is shown as looped around the stationary weft-horn 104,
and the weft-carrier 117 is illustrated as moving forward to insert the weft into
the shed.
As this operation takes place, the loop of the weft passing around the stationary
horn 104 will be held from bearing on the edge of the warp or shed.
At the proper time the cam 111 will operate the lever 109, which, by the
connections described, will raise the upper end of the detacher 106 so that the
loop of the weft will be raised off of the weft-horn 104, whereby, as the tension
device acts, this part of the weft can be drawn tightly against the edge of the
shed.
As the filler or needle 117 is withdrawn from within front of the lay 101, the lay
will beat up the loop of filling just inserted.
As the lay moves forward towards the breast-beam 100, the guide 115 will strike
against the weft, of which there is only a single thread between the lay and
the breast-beam as the needle 117 is out of the way, and will push the same
into the guide-way formed between the point of the detacher 106 and the end of
the retainer 113.
As the lay continues its forward movement, the cam 116 will bear on the lower
side of the end of the detacher 106 to raise the same so that the guide 115 can
push the weft along the top of the detacher 106 into the notch 114; then as the
lay retreats and the filler or needle 117 again advances, the weft will be looped
around the horn 104, as the detacher will drop to its normal position, as shown in
Fig. 1.
By this means a very simple and accurate weft controlling mechanism is provided,
and one which will greatly facilitate the action of the loom, as, with a stationary
weft horn, the weft that has been woven will be held accurately and nicely in place
as the next loop is inserted.
In some instances, the retainer 113 may be omitted, but the same is useful in
holding the weft after it has been looped or lifted on to the stationary horn
in position until the needle 117 has entered between the lay and the breast-beam.
Of course, when the detacher is lifted, the weft is not under the retainer 113,
as the loop then is entirely inside of the retainer 113, as indicated in Fig. 2.
Looms have heretofore been provided with movable weft-horns, but this invention
greatly simplifies the operation, as, by using a stationary weft-horn, all that is
necessary is to detach the weft therefrom, and replace the same on the weft-horn
at the proper times, which can be done much more readily than to move the weft-
horn to various positions.
Of course this invention can be applied to a loom in which the weft is inserted
by other means than a needle, and the details herein described may be greatly varied
by a skilled mechanic without departing from the scope of the invention, as
expressed in the claims.
Having now particularly described and ascertained the nature of this said inven-
tion and in what manner the same is to be performed I declare that what
claim is :-

page_text: 2. The combination in a loom of a stationary weft-horn and mechanism for
detaching the loop of weft from the horu, substantially as described.
3. The combination in a loom of a stationary weft-horn, means for lifting the
loop of weft off of the horn, and mechanism for replacing the weft in position to
engage the horn, substantially as described.
4. The combination in a loom of a stationary weft-horn, mechanism for detaching
the weft from the horn, and means carried by the lay for replacing the weft in
position to engage the horn, substantially as described.
5. The combination in a loom of a stationary weft-horn, a movable detacher, cam
mechanism for lifting the detacher, a guide and cam carried by the lay for lifting
the detacher and carrying the weft in position to engage the horn, substantially as
described.
