WEIET-REPLENISHING LOOM.

Application led December 4, 1925. Serial No. 73,245.

This invention relates to a weft replenishing loom of the pick and pick type, that is, to an automatic loom in which any one of the shuttles may be picked in either direction at any time, as distinguished from looms in which each shuttle must make at least two successive picks Whenever it comes into operation.

Tt is the general object of my invention to provide a weft-replenishing, pick and pick loom in which approaching weft exhaustion is indicated at the non-replenishing side of the loom and in which the weft is auto matically replenished at the opposite or magazine side of the loom.

It has been noted in prior automatic pick and pick looms that a weft carrier is frequently transferred to a shuttle which thereshorter time, while some other shuttle becomes active. This delay of the replenished shuttle frequently causes breakage of the weft end which leads from the shuttle to Vthe stationary end holder of the loom. This Aecordincl another ob'ect of m invenh ya tion is the provision ot' mechanism by Which a weft transfer can be effected only to a shuttle about to become active. This I conis of very great importance. I p

My invention further relates to the provision of a mechanical feeler of a new and improved construction, to an improved transferring mechanism, and to the provision of means includingY a special pattern chain construction by which the mechanical feeler may be operatively positioned with relation to a shuttle about to become active.

My invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly` pointed out in the appended claims.

General dcscn'ptz'on of the Zoom.

also provided at the left handisidc of the loom and is movable by pattern controlled devices into position to co-operate with any selected shuttle box.

The pattern mechanism is so designed that .the feeler will be positioned to co-operate with the shuttle which is about to become active. Provision is also made by which the feeler, after being thus positioned, will moveI with the associated shuttle as it is raised or lowered to picking position. A transfer mechanism is provided at the magazine side of the loom and is adapted to transfer a weft carrier horizontally to th'e shuttle which is about to become active.

Referring to--the drawings, l have shown portions of a loom frame 30` (Fig. 2) on which is mounted a lay 31 actuated by the usual crank shaft 32 and connecting rod 33. Drop boxes 34 are mounted on the left hand or detecting end of the lay and these boxes are movable vertically by drop box actuating' mechanism of any usual or commercial type.

lAs shown in the drawings, a lifter rod 35 is connected to a lever 36 having a floating center 37 and vsupported by `angle-levers 4Q and 41, which in turn are connected by links 42 and 43 to vibrator gears 44 which are intermittently actuated by the usual cylinder gears 45 and 46. The vibrator gears are mounted on vibrator levers 47 which are connected by links 48 to the usual pattern controlled levers 49 (Fig. 8). A suitable give-way connection is referably provided between the two parts o the floating lever 36.

Similar drop boxes 50 (Fig. 11) are provided at the magazine end of the loom and suitable connections to be described cause the two sets of drop boxes to raise and fall simultaneously.

Detecting mechanism.

The detecting mechanism is shown on an enlarged scale in Figs. 6 and 7 and comprises a detecting member or feeler mounted for both sliding and swinging movement in a'stand 61 which is pivoted at its forward end upon a stud 62. The stud 62 is mounted in an arm G3 which in turn swings about a fixed pivot or stud 64. The detecting member 60 is of the well known side slip type and is pressed yieldingly rearward by a spring 65. A cross piece 66 secured to the detector 60 engagesan inclined bearing surface 6T on the stand 61 and normally positions the detector 60 as shown in Fig. 6.

When the detector engages a substantially,l

exhausted weft.carrier, the .detector slidesl along the relatively smooth surface of the bobbin or weft carrier toward the right, thus projecting a plunger 68 (Fig. 4) into the path of an actuating member 69 (Fig. 3). This member 69 is connected by a bell crank 70 and link 71 to a lever 72 which is rocked by a cam 73 on every pick of the loom, thereby causing the member 69 to more forward. If the plunger 68 is projected into the path of the member 69, the plunger 68 and its supporting member 74 are pushed forward, rocking the arm 75 to which the member 7 4 is connected and thus turning the shaft 7 6 on which the arm 75 is mounted.

The shaft 76 extends across the front of the loom to the magazine side where it is provided with an arm 77 (Fig. 1) connected to a rod 78 which controls the indil plunger 68 to be swung forward for transfer indication and alsof permit the stand 61 to be moved to different vertical positions as will now be described.

Detector position-ing devices. r1 he arm 63 (Fig. 6) which supports the stud 62 is connected by a yielding link 80 (Figs. 6 and 8) to a lever 81 mounted on the stud 82 (Fig. 8) fixed to the loom frame 30. An indicating lever 83 (Fig. 8) .is pivoted at 84 on a fixed bracket 85 and is connected by a link 86 to the lever` 81.- The lever 83 is connected at its opposite end by a link 87 to a pattern lever 88 which co perat with a portion of the drop box pattern chain 89 (Fig. The stand 61 (Fig. 6).1s similarly oonnected by a yielding link 90 (Fig. 7) t0 a lever 91 pivoted at 82 and connected by a link 93 (Fig. 2) to an indicating lever 94 mounted on a fixed pivot 95. The lever 94 is connected by a link 96 to a second pattern lever 97, as in the connections previously described.

The pattern chain 89 (Fig. 2)- for controlling the pattern levers 88 and 97 is preferably provided with chain rolls of Vthree different diameters as indicated at 100, 101

102 in Fig. 10.

In the arrangement marked A, two of the medium size rolls 100 position the stand 61 to co-operate with a shuttle which is positioned level with the shuttle race. In the arrangement B, I use amedium roll 100 to position the connector 90 for the stand 61 and a large roll 101 to position the. connector 80 for the arm 68. This moves the stand 61 so that the detector will co-operate withabove the running position and s'milarly a combination of two small rolls 102, as shown in arrangement E, will position the stand 61 so that the detector will co-operate with a shuttle which is two spaces below the running position.

By the use of two indicating levers and a chain constructed as above described. I am thus able to give the detector five different operative positions. The pattern chain 89 (Fig. 2) is intermittently moved ahead approximately one half pick earlier than the drop box mechanism.

The detector Sama 61 (Fig. e) is provided with a rearwardly extending stud or projection 106 adapted to enter any one of a series of holes 107 (Fig. 7) in a strap or bracket 108 fixed to and movable with the drop boxes 34. The stand 61 and projection 106 are positioned as above described just prior to the forward movement of the lay and such forward movement causes the projection 106 to enter that one of the holes 107 which is associated with the selected shuttle box which 'is about to supply the running shuttle.

v The detector will thus be held in operative relation with the selected Ashuttle as the drop boxes rise or fall, the stand 61 being swung upward or downward by its 'connection through the projection 106 to the shuttle box and such swinging movement permitted by the 'yielding construction of the links 80 and 90,' as indicated in Fig. 7 l Y I have thus provided a mechanical weft detector or feeler which will be moved in advance to co-operate with the shuttle which lis about to become active. If this shuttle is thereafter raised or lowered to bring it to operative position, the detector will swing with the drop boxes and will maintain its operative detecting relation to the weft carrier in the shuttle. If the weft carrier is substantially exhausted, the detector will slip side-ways, advancing the plunger 68 (Fig. 4) into the path of the actuating membei' 69 and rocking the shaft 76 to indicate weft exhaustion. A lost-motion slotted connection (Fig. 6) between the detector 60 and the plunger 68 prevents movement of the latter by the ordinary forward movement of the detector.

Weiz.L replenskz'ng magazine,

The magazine 110 (Fig. 1') is in general of the usual multicolor stationary magazine type and is shown herein as providing for the use and control of three different kinds or `-colors of weft carriers. The usual color slide 111 is connected by a bell crank 112, connector 113 and other connections (not shown) to the drop box actua-tingmechanism so that the magazine will always be set to release a weft carrier corresponding in color to the running shuttle, this being the usual arrangement in weft replenishing drop box looms.

For a detailed description of the type of mechanism shown in the drawings, reference is made to the prior patent to Ryon, No. 1,030,748 issued, June 25, 1912.

The color slide is arranged to be rocked by a link 114 (Fig. 1) upon indica-tion of weft exhaustion, which is evidenced by projection of the plunger 78 (Fig. 1) into the path of a floating lever or actuator v115 (Fig. 22) which is rocked at yevery pick by a link 116 (Fig. 1) and cam lever 117, actuated in turn by a .continuously rotating double cam '118.'l

Upon indication of ,weft` exhaustion, a

bobbin of the selected color is released by the -does not occur until just prior to the flight of the replenished shuttle from the'magazine end of the loom.

y V Traneferrtg mechanism.

The transferring mechanism in my iin- Eroved loom is arranged to transfer the obbin horizontally through the front side` of the shuttle box and to eject the exhausted izo bobbin through an opening in the rear side thereof. The transferring mechanism is movable vertically to bring it into co-operation with the shuttle' box which is about to be positioned at the level of the shuttle race.

For this purpose the bobbin vholder and transferrer are supported and actuated in a manner similar to the arrangement for the weft detector stand 61, the bobbin holder being swung vertically simultaneously with the detector stand.

Referring particularly to Figs. 15 .to 18, the bobbin hglder 120 (Fig. 15) is provided with forwardly projecting arms 121 pivoted on studs 122 in' the swinging forward ends of arms or levers 123 which in turn are mounted upon fixed pivot'studs 124. The left hand arm 121 is connected by a vielding link 125 (Fig. 12) to a lever 126 (Fig. 11) pivoted at 127 and connected by a link 128, a bell crank 129 (Fig. 15a), an adjustable connecting rod 130, a bell crank 131 and a link 132 to the lever 91 (Fig. 8) by which the detector stand 61 is positioned.

The arm 123 (Fig. 15) is similarly connected through a yielding link 133 (Fig. 12),

a lever 134 and a link 135 (Fig. 13) toy duplicate bell cranks and connecting rods through which connection is made to a link 136 (Fig. 8) pivoted at its upper end on the lever 81 which positions the arm 63 on which the detector stand 61 is pivoted.

By these connections the bobbin holder 120 is swung about its centers 122 and 124 (Fig. 15) to any one of five different positions corresponding tothe positions A, B, C, D and E of the weft detector as indicated in Fig. 10, This positioning. movement takes place shortly prior to the movement ,of the drop boxes and associates the bobbin holder and transferrer with the shuttle box about to assume active or running position and about to receive the indicated shuttle.

The'bobbin holder 12() is provided with a flat bottom portion 14() (Fig. 15) and with side flanges 141 (Fig. 18) which are grooved to furnish guide-ways for the Vtransferrer 142. A lug 143 (Figi 15) on the side of the bobbin holder 120 is provided with an adjustable stud 144 which projects rearward and is adapted to enter one of a series of v'guide openings 145 (Fig. 20) in a strap or bracket 146 secured toA the'frame 147 of the `drop boxes 5 0v at the magazine side of thev loom. s A

These drop boxes` are supported by the usual? lifter rod 148 which is shifted vertically inunison with the lifter rod 35 at the opposite iside of v the loom through connectionsindicateddiagrammatically in Fig. 21.

These connections comprise an arm 149 zmounted` on q a' rock shaft 150i and-connected to the lower end of the lifter rod 148. y second arm 1'51 is connected to the lifter rod 35 (Fig. 2) so that the two sets of drop boxes will move together and that corresponding shuttle boxes on opposite sides of the loom will always lie in the same horizontal plane.

As the boxes are shifted, the stud 144 and strap or bracket 146 keep the bobbin holder and transferrer in operative relation with the selected shuttle box during the vertical shifting movements of the boxes.

Trans/errer actuating mechanism.

The transferrer 142 is actuated to force the ,bobbin rearward in the bobbin holder 140 and thereby effect transfer to the -exhausted shuttle. For this purpose, the transferrer is provided with a forwardly extending arm 154 (Figu15) forked to receive the slotted upper end of a transfer lever 155 (Fig. 13) mounted upon a fixed pivot 156 and having an elongated slot at its upper end through which extendsy a stud 158 (Fig. 17), mounted in the forked arm 154 ot' the transferrer 142. This slotted connection between the transferrer and the transfer lever provides a continuous operative connection, while permitting angular movement of the `transferrer with the bobbin holder.

At its lower end the lever 11) is provided with a latch 160 which is normally positioned out of the path of movement of a bunter 161 by which it is actuated (1o-transfer a bobbin. The bunter 161 is preferably xed to the front end of a rod 162 (Fig. 11) slidable in a bearing 163 and having a pin and slot connection at its rear end to a lever 164 actuated 'by a cam 165 on thebottom or cam shaft '166. This cam 165 is preferably double-acting, as shown in the drawings, so that the bunter 161 is moved forward at every pick of the loom.'

The latch 160 is controlled through a link 166 (Fig. 11) from the upper shaft 168 (Fg.1) of the magazine, which is actuated vin the usual manner to raise the latch when Rabbin support md release.

The bobbin holder 120 (Fig. 15) is provided with a door o rtrap 170 (Fig. 17) in the bottom 14()l thereof, upon which trap the bobbin B rests while awaiting transfer. The bobbin is retained in' this position by yielding spring clips or retainers 171 and 172 (Fig. 18). The trap 170 visv held normallycloscd by springs v173 and 174, the closed position being regulated by an adjusting screw 175 (Fig. 17).

A depending rod 176 is pivoted at 177 to the trap 170. The' rod 176 is slidable through a recess 177 in a. plate 178, pvoted to the upper end of an actuating rod 179.

' The rod 179 is moved vertically at -every pick of the loom in some convenient manner as by a suitable connection (not shown) to the cam lever 164.

When in its upper position, the plate 178 engages a stop pin 180 (Fig. 17) and is thereby moved to horizontal position against the tension of a spring 181 by which it is normally swung upward about its pivot-on the rod 179. lVhen the plate 178 is in horizontal position, the rod 176 is freely slidable through the opening 177 as the .bobbin holder and transferrer are moved vertically with the drop boxes. Willen the rod 179 is depressed, however, the plate 178 swings angularly to grip and depress the rod 76, thus opening the trap 170 and releasing the bobbin resting thereon, if for any reason the bobbin has failed to be transferred.

Shuttle bom const-mation.'

The shuttle boxes at the magazine side of the loom are of special construction to permit horizontal transfer of the bobbins. Referring to Figs, 19 and 20, it will be seen that the lay end 183 is provided with a large rear opening 184 through which the exhausted bobbins may be ejected. The extreme outer portion of the lay end 183 is also slotted as indicated at 185 to provide a continuation of the opening 184 through which any trailing weft ends may be drawn out of the path of an in-coming shuttle.

A drop box frame 147 for the boxes 50 is similarly lprovided with a series of rear openings 186, one opening being positioned opposite each of the boxes. The shuttle binders 187 (Fig. 16) are also provided with openings 188 and with a narrow slot 189 between the upper and lower parts of the binder.I The binders are provided with the usual springs 190 which, are forked to engage the upper and `lower portions of the binders and' to prevent obstruction to the transfer of the bobbins. Each shuttle box has a large opening 191 at its front side, as shown in Fig. 23, and also has a slot 192 at the inner end thereof, between the front side of box plate and the top of the shuttle box.

These narrow slots 189 and 192 permit the weft thread WV attached to ay transferred bobbin to be drawn entirely free of the binder and shuttle box as the latter moves rearwardly and the shuttle is picked from the box the end of the weft threadbcing still attached to the weft end holder and the shuttle being not yet threaded. (See Fig.- 24).

The chance of weft breakage is thus substany tially reduced.

Having described the construction of my improved loom, I will now indicate briefly the method of operation thereof.

` The detector stand 61 and the bobbin holder 120 are moved through connections from the indicator levers 88 and 97 so that they are positioned in alignment with that shuttle which is about to become active, this positioning occurring in advance ofthe shifting of the drop boxes. During the shifting of the drop boxes,v the boxes also move forward and the detector, being retained in operative relation with the shuttle about to become active, thereupon indicates the condition of the weft supply therein.

If the weft is substantially exhausted, the' detector will slip along toward the tip of the bobbin, advancing the plunger 68 (Fig. 4) into the path ofthe actuator 69 (Fig. and thus causing movement of the rock shaft 76, thereby rendering the actuator rod 116 (Fig. 1) effective to r'ock the color slide 111 which is maintained in selective position corresponding to the running shuttle by its connection to the pattern levers which control the drop boxes.

A fresh bobbin is thus advanced to intermediate position before the exhausted shuttle is received at the magazine side of the loom. The bobbin is held in its cradle in intermediate position until the exhausted shuttle has been sent to the magazine side ot' the loom and until the substantially exhausted shuttle is about to again become aetive. At this time the color slide 111 will again be moved to a position corresponding to the partially released bobbin, and the rocking of the color slide will fully release the bobbin and will allow it to fall into the bobbin holder, at the same time raising the latch160 into the path of the bunter 161. This selective axial movement of the color slide and also its rocking movement occurs on every pick of the loom, instead of on every second pick, which is -the usual arrangement. 'lhe axial movement is preferably controlled from the drop box pattern and takes place just prior to the rocking movement thereof. ln other words, the color slide is moved lo a position corresponding to the shuttle next to be picked ust prior to the actuation of the mechanism for finally releasing thebobbin and for raising the latch 160 to operative position.

AS 4the bunter thereupon advances, the transferrer 142 will be moved rearward and such movement, combined with the forward movement of the lay, will cause the fresh bobbin to be inserted in the exhausted shut-tle and the spent bobbin to be ejected through the rear opening of the drop boxes and lay end.

By the mechanism above described, I am thus able to effectively transfer a fresh bobbin to a substantially exhausted shuttle and to make such transfer just prior to the picking of the replenished shuttle from the magazine side of the loom. This latter result is particularly important, as it prevents transfer of a bobbbin to a shuttle which is about to remain idle at the magazine side of the loom for a longer or shorter period of time, during which time the fresh weft end would very probably be broken by the movement of the lay while the end was attached to the fixed end holder of the loom.

`If the bobbin fails of transfer, the revoking mechanism opens the trap 170 in the bobbin holder 140 and thus removes the untransferred bobbin. y
