Another feature of the invention resides in
35. the provision of a weft replenishing mechanism
which may be separately constructed and in
corporated in a loom of standard design.
A further object is to provide novel means for
feeling the shuttles ‘to determine whether they
need replacing.
A still further object is to provide improved
means for storing full shuttles ready for inser
tion into the ,loom.
The invention also contemplates novel and. im
i. proved means for synchronizing the loom start
ing and stopping mechanism and the shuttle ex
changing mechanism.
Also contemplated are various safety features
designed to protect the loom mechanism should a
shuttle become inadvertently jammed during the
replacing operation.

The loom inthe usual manner is. provided with.
a‘ shipper handle H, a clutch C and a. brake B,
the latter two» being controlled by said handle.
Thus, when the loom is started the shipper handle
is moved to release the brake and engage the 40
clutch, the reverse being true when the loom is to
The mechanism contemplated. in the present
invention is designed to automatically declutch
the machine and set the brake to stop the opera 45
tionof the loom when a full shuttle is to be ex
changedfor an empty one; and to automatically
reclutch the machine and release the brake-after
the change has been made so the loom may con
tinue itsoperative function.
In the usual manner and referring more par
ticularlyto Fig. 2, themachine is provided with
a lay. L. which is oscillated through the medium
of ,- a. crank- 25 on 'a crankshaft 26 by means of
a connecting link or links 21.
The previously
mentioned clutch and brake, control the shaft 26
and thus the operation of the loom. In timed
relation with the crankshaft 26, the loom is pro
vided with a camshaft 28, the present ratio being
two revolutions of the crankshaft for each revo-'
lution of the camshaft.
On the camshaft 28 there is provided a cam 29
having a projection 39 and a slightly depressed
portion 3| on the periphery thereof.

is clearly seen in Figs. '7 and 8.
When the pawl 58 is moved to rock the rock
lever 5|, the control lever 56 is moved out of
engagement with the mentioned stop end of the
lock motion lever permitting the spring 63 to rock
the last-mentioned lever about its pivot and to
cause the pin 6| to seek and enter the ?rst of the
holes 62 which it may ?nd as the gear 49 rotates.
10 with said cam there is one arm 32 of a bell - In this manner, the rotation of the gear 49 is 10

of the dog 35 there is preferably connected a rod in Fig. 9 wherein one or more pins 64 are driven
15 31 which is moved by the ?oating core of a sole» through the hub 65 on the gear 49 and into en 15

Upon the shaft 44 there is provided a cam 61
and engaged with said cam there is provided a
lever 68 mounted on the shaft 43. The free end 20
of the lever 58 is connected by means of a rod
20 35.
When the solenoid core is in the low or
deenergized position the bifurcation 36 will pass
beneath, and therefore, out of engagement with
lug 39 carried by a shift rod 49 which is arranged
to have connection through the medium of .a
25 rod 4|, with the shipper handle. Similarly, it
can be seen that when the solenoid core is in the
high or energized position the mentioned bifur
cation will engage said lug 39 to shift the rods
48 and 4| and thus move the shipper handle H
30 to set the brake and declutch the machine. The
Substantially simultaneously with the opening
stopping the operation of the loom. The means
for energizing the solenoid will be later described.
It is desired in the present instance when the
loom is brought to a stop in its operation, to set
in motion mechanism for effecting the exchange
provided between the collar ‘H and the abutment
for an empty shuttle ofa full one so the loom
18 so that the front wall ‘H of the box opens in
advance of the actuation of the ejector 14. The
return movement of the front wall ‘H and the
ejector is effected through the medium of the 40
respective springs 19 and 19“. (Figs. 5 and 6.)
The ejector ‘I4 dislodges a shuttle in the box
12 which then falls in a receiving box |2|, being
guided by a leather apron |22 or the like.
To further complete the description of the box 45
may continue its weaving operation. For this
purpose there is provided a transmission box 42 in
which are located parallel shafts 43, 44. -On the
former there is loosely mounted a sprocket 45
connected as by means of a chain 46 to a sprocket
41 on the camshaft 26. Carried with the sprocket
and also free of the shaft 43 there is provided
, a pinion 48 in mesh with a gear 49 mounted for
pivot 13 as shown in Fig. 6.
of the box 72, means for ejecting a shuttle from 30
said box is brought into operation. The shuttle
ejector 14 is moved by a lever 15 through a rod
connection 16, said latter being provided with a
collar Tl engaged by an abutment 18 carried
by the rod 69. A slight amount of free play is 35
above, is therefore, a cam controlled means for
69 to an arm ‘E0 on the movable front wall ‘H of
a shuttle box 12. Hence, the engagement of said
lever 68 with the high point of said cam will
cause, when the shaft 44 is rotated, said lever to 25
be depressed to open the box 12 by moving the
front wall ‘H outward and upward around its
rotation on the shaft 44. Since both the pinion
49 and the shaft 49 are freely mounted on their
respective shafts, the mechanism in the transmis
sion box 42 will remain at rest during the op
eration of the loom.
The mentioned transmission mechanism best
shown in Figs. '7 and 8, will be set in motion
when the bifurcation 36 on the dog 35 engages
the lug 39. This is accomplished by the shift
rod 49 which carries a pivoted pawl 50 engaged
with a rock lever 5| in the form of a bell crank
12, means are provided as a check for the picker
stick P, said means comprising a springcheck
such as is generaly shown at 89.
Upon the shaft 44, there is provided another
cam 8| with which is engaged a lever 82 also 50
mounted on the shaft 43. This cam and lever
are designed to actuate the mechanism for pro
viding a full shuttle for insertion into the box 12
after an empty one has been ejected from said
box. To this end a shuttle magazine 83 is pro 55
vided and in the present instance comprises a
medium of a link 53 with a lever 54 mounted on
magazine having two compartments 84 and 85,
each of which is arranged to support shuttles in
a shaft 55 journalled in the transmission box 42.
60 Upon the shaft 55 there is also mounted a control
lever 56, the free end of which is arranged to
engage the end 5'!‘ of a lock motion lever 58. This
latter lever is pivotally mounted upon a member
stacked relation, the lowermost shuttle of each
stack being respectively supported upon the in
reaching ends 88 and 87 of bell crank levers
88—88a and 99—89a.
The lever 89 is provided with a sleeve 98 hav
pivoted at 52 and having connection through the
59 keyed .at 68 to the shaft 44 and arranged
65 alongside of the gear 49.
The end of the lock motion lever 58 opposite
to the stop end is provided with a pin or the
like 6| and the gear 49 is provided with a plu
rality of holes or seats 62 which are adapted to
receive the pin 6| in a manner later set forth.
A spring 63 is arranged between lock motion lever
58 and the member 59 to tend to urge the pin
6| into one of the holes 62. Normally, however,
the free end of the lever 56 engages the stop end
57 of the lock motion lever to hold said pin out of
ing an arm 9| a?ixed thereto and the lever 89a
is similarly provided with a sleeve 98a having an 65
arm 9|a af?xed thereto. A link 92 connects the
free ends of the arms 9| and 9|a.
The arm 88 is provided with a shaft 93 pro
jecting through the sleeve 96 and has a?ixed
thereon an arm 94.
In a like manner, the lever 70
88a is provided with a shaft 93a having a lever
portion 94a. The free ends of the levers or arms
94, 940., are connected as by the link 95.
The arm 9| or the sleeve 90 may have a?ixed
thereto an arm 96 substantially at right angles to 75

In relation to the shuttle box there is arranged
a pair of feelers I30 and I3I, the former being
10 adapted to be contacted by the quill of a shuttle
in the upper compartment I2Il_ and the latter by
the quill of a shuttle in the lower compartment
Each feeler comprises a vertically disposed plate
I32, ?xedly but adjustably carried at I33 by the
lay. Each plate I 32 is formed with curved lip
portion I34 having a slot I35,_said lip portion be
ing formedon the ends of the plates I32 nearest
the quills. The opposite end of each plate is
20 formed with a ?ange I36 and provided with a
hole for the passage th'erethrough of a stem I31
of a feeler member I38 which‘ is engaged in the
slot I35. Each feeler member I38 is provided at
its ‘end with a plurality of slits, serrations,
25 knurls, or the like I39, these ends being adapted
to feel or engage against the vyarn on the quills
by means of compression springs I40 disposed be
tween abutments on the feeler members and the
During the cycle of movement of the mentioned
cams, the depleted shuttle in the box ‘I2 will be
ejected and immediately subsequently a full
shuttle from the magazine will be fed to the
empty box 12, which will then close. At this :
time, the brake will be released and the clutch
reengaged to restart the loom.
While a preferred form of the invention has
been disclosed, the type of mechanism which may
be employed to carry out the concepts of the in 110
vention, may be changed in many ways by skilled
persons without departing from the spirit and
scope of the invention as claimed.
Hence, the
prior art rather than the instant disclosure
should form the basis of interpretation of the
scope ‘of the invention.
‘What is claimed as new and desired to obtain
by Letters Patent is:--
1. In‘ a multicolor weft replenishing loom hav
ing a multistack shuttle magazine, the combina- ~
tion with weft replenishing means at an end of
the loom, of mechanism for stopping the opera
tion of the loom upon depletion of weft and hav

nected therewith and carrying an arm, a member =1
having a notched portion in position to be en
gaged by said arm and movable thereby upon
movement of said shift element, unitary one
' cycle actuating means arranged at the end of the
?anges I36.
It is apparent from the above that when the
shuttle box is moved to bring a yarn covered
quill into contact with a feeler member, that
member will be moved in a straight line against
its spring since the mentioned slits I39 will have
35 effective contact with the yarn on that quill.
When the yarn on a quill has become depleted
the quill will be exposed to contact by the feeler
member. Now, when the feeler member is urged
back, it will slide along the smooth surface of the
40 quill and thus become cocked as shown in Fig.
10. In this condition, it will come in contact
with a contact member I42 carried by the plate
I32 but insulated therefrom. An electrical con
nection I43 is made between the feelers and the
solenoid 38 and when the mentioned contact is
made said solenoid is energized as previously
