- the inner end of shaft 31 has a crank member 42 assembled thereon which is adapted to rotate with said shaft 31.
- One end of a pitman 43 is pivotably attached to the crank member 42 by means of a bolt 44 and the opposite end ispivotably attached to the upper portion of a crank arm generally indicated by numeral 45 (FIGS. 2, 4 and 5)
- the lower end of the crank arm 45 is in the form of a hub 46 which supports said crank arm for oscillating movement by the pitman 43 on a horizontally disposed plunger arm shaft 47.
- the plunger arm shaft extends below and transversely of the inclined track and is supported by and journaled in aligned bearing members 48 and 49 (FIG. 8) that are assembled in the upper portion of upwardly directed support arms 50 and 51 which are fixedly attached in opposed relation at their lower ends to the supporting base 14.
- crank arm 45 The upper end of the crank arm 45 is provided with an integrally formed arcuated finger 52 and is so disposed as to extend in a direction away from the crank arms point of assembly with thepitman 43 (FIG. 2).
- a transverse slot 53 is provided at the top of the crank arm and communicates with the upper surface of the arcuated finger 52.
- a collar 54 serves as a means for maintaining the crank arm 45 in position on the plunger arm shaft 47 and in operating alignment with the crank member 42 and pitman 43.
- crank feed arm 55 is provided which is fixedly assembled on the plunger arm shaft 47 and, extending generally upwardly, it protrudes slightly above the crank arm 45 when in alignment therewith.
- the uppermost end of the crank feed arm 55 is 4 bifurcated as at 56 (FIGS. 2 and 5) and supports therein a pivotable key 57.
- the pivotable key is at times suspended and at others released to contact the supper surface of the arcuated finger 52 of the crank arm 45.
- the pivotable key When the pivotable key is in contact with the arcuated finger said key will drop into the transverse slot 53 of the crank arm as the latter is caused to move forwardly or in a clockwise direction as viewed in FIG. 2 by action of the crank member 42 and pitman 43.
- crank feed arm 55 When the pivotable key 57 drops into the transverse slot 53 is locks the crank feed arm 55 in alignment with the crank arm 45 and as the latter arm moves rearwardly through action of the pitman and crank, said crank feed arm is caused to move with the crank arm, thereby causing the plunger arm shaft 47 to rotate a predetermined number of degrees in the direction of the indicating arrow 58 shown in FIG. 2.
- plunger feed arm 59 is fixedly attached to the plunger arm shaft 47 intermediate its ends and at a position approximately midway between the support arms 50 and 51 (FIGS. 2 and -8).
- the opposite end of plunger feed arm supports a plunger member generally indicated by numeral 60 for movement in a vertical plane as said plunger feed arm is caused to move from the phantom line to solid line position, shown in FIG. 2, by the rotational movement of the plunger arm shaft 47.
- the plunger member 60 includes a lower horizontally disposed rod 61 with a pair of guide rods 62 and 63 suitably attached to and extending upwardly from the ends of said rod -61.
- Guide rods 62 and 63 are guided for vertical movement in aligned apertures 64 and 65, respectively, provided in a guide bracket 66 disposed beneath the container loading position of the inclined track.
- the guide bracket 66 extends between a pair of the frame elements 13 and is attached to the latter by means of bolts 67 and nuts 68.
- the upper ends of the guide rods '62 and 63 are interconnected by a bar 69 (FIGS. 2 and 8) which serves as a means for pushing the bobbins upwardly into the container 17 and will be more fully described hereinafter.
- That portion of the plunger feed arm, which supports rod 61, of the plunger member 60 defines an elongated opening 70 that is formed from a piece of fiat stock and attached to said arm by cap screws 71 (FIG. 2).
- This elongated opening 70 prevents any possible binding of the plunger member as it is caused to reciprocate by permitting the rod 61 to move within the limits of said openmg.
- the lower tip portion is caused to contact an eccentric disc 72.
- This disc may be rotated to any desired position and is supported by a shaft 73 the ends of which are suitably attached to a pair of the frame elements 13.
- a hopper element 74 shown in FIGS. 2 and 5 assembles on the upper portion of the supporting frame 18 shown in FIG. 1 and is adapted to receive warp tubes or so-called bobbins which have been stripped and in condition to have new yarn packages built thereon.
- the hopper element communicates with an enclosed bobbin chute 75 centrally disposed in the upper portion of the supporting frame 18 and extending downwardly the lower portion of said chute communicates with an angularly directed chute 76 (FIGS. 1, 2 and 5).
- This chute guides the bobbins to an inclined chute 77 (FIG. 2) which is positioned directly below the container loading position on the inclined track.
- the bobbins 78 (FIG. 2) are caused to roll to a position directly above the bar 69 of the plunger member 60 when received into the inclined chute 77. At this point the latter communicates with an upwardly directed guide chute 79 the upper portion of which is provided with a pair of opposed spring biased gate members 80 and 81.
- gate members extend between the rail members 11 and 12 of the inclined track and when a container 17 moves into lOading position a door 82 (FIG. 2) in the bottom thereof is automatically opened by cam means 83 and 84 (FIG. 3) which are fixedly attached to the rail members 11 and 12, respectively.
- FIG; 2 illustrates the manner and mechanism for individual guidance and advancement of the bobbins 78 from the hopper element 74 through the communicating" chutes to the container 17.
- the upper bobbin as it moves downwardly in the enclosed bobbin chute 75 contacts a bobbin sensing element or indicator door 85 and pivots it downwardly to the solid line position shown in this figure of drawing. Further movement of the bobbin is restricted by a pivotable escape.
- - ment latch 86 which as shown in FIG. 5 is supported for pivotable movement on a rod 87.
- Rod 87 is journaled in spaced bearing elements 88 and 89 which are attached to one side of the enclosed bobbin chute 75 by means of screws 90 and 91, respectively.
- a portion of the escapement latch 86 protrudes through an opening 92 (FIG. 5) into the enclosed chute 75 with said portion being recessed as at 93 (FIG. 2).
- Recess 93 is adapted to receive the bobbin and retain it until the escapement latch is caused to pivot in a manner to be described.
- a lever 94 is fixed to one end of rod 87, and by means of a coil spring 95 interconnecting the free end thereof with an ear 96 (FIG. 2) disposed below and which forms a part of the enclosed chute 75, the escapement latch 86 is continuously urged to that position for retainment of a bobbin within said chute.
- Indicator door 85 is fixed to a lever 97 which is pivotably mounted on a support 98 and movement of said indicator door to vertical position shown in FIG. 2 causes said lever 97 to pivot upwardly to the solid line position shown in this figure of drawing.
- a vertically disposed linkage rod 99 is pivotably attached at its upper end to the outer end of lever 97 and the lower end is pivotably attached to one end of a double armed lever 100 as at'101.
- This lever is pivotably mounted intermediate its ends as at 102 and that end opposite the connection to linkage rod 99 is adapted to support the pivotable key 57 carried by the crank feed arm 55 in an elevated position out of contact with the arcuated finger 52 of the crank arm 45.
- the crank arm moves forwardly or in a clockwise direction as viewed in FIG. 2, the pivotable key 57 drops into the transverse slot 53 of the crank arm 45 to lock the crank feed arm 55 in alignment with said crank arm.
- the crank feed arm moves with it and rotates the plunger arm shaft 47 in the direction of the indicating arrow 58 in FIG, 2.
- Rotation of the plunger arm shaft 47 in this direction causes the plunger feed arm 59 to pivot to the solid line position shown in FIG. 2 and the plunger member 60 supported thereby moves upwardly through the guide chute 79 pushing a bobbin 78 through the gate members 80 and 81 and into the container 17.
- the gate members being spring biased one toward the other prevents the bobbins from dropping back into the guide chute 79 when the plunger returns to its initial position.
- crank feed arm 55 As the crank arm 45 and crank feed arm 55 approach back center or their rearmost position, the upper end of said crank feed arm contacts a depending arm 103 of a bell crank lever generally indicated by numeral 104 and pivots it from the dotted to solid line position shown in FIG. 2.
- This bell crank lever 104 is pivotably mounted to a support bracket 105 and the second arm 106 thereof is connected by means of a link element 107 to the end of one arm 108 of a second bell crank lever generally indicated by numeral 109 (FIG. 2).
- This lever is pivotably supported to a bracket 110 and the second arm 111 thereof is interconnected to the escapement latch 86 by means of a link rod 112.
- Link rod 112 is pivotably attached to a rod 113 (FIG. 5) which extends from the escapement latch 86 and movement of the bell crank lever 104 as described causes the linkage connected thereto to move the link rod 112 in the direction of the indicating arrow 114 shown in FIG. 2. This movement pivots the escapement latch 86 and releases the bobbin 78 retained thereby permitting continued advancement of the latter through the chute elements to the position where it will be raised by the plunger member 60 for insertion into the container 17.
- a continued flow of bobbins into the enclosed chute 75 maintains the indicator door in a generally vertical position and the bobbins are individually and continually advanced through the chutes and loaded into the container 17 by the plunger member 60.
- An electrically controlled counting mechanism governs the number of bobbins that are loaded into a given container 17 which will now be described.
- the escapement latch 86 When the escapement latch 86 is actuated in the manner heretofore described, the second arm 111 of the bell crank lever 109 is caused to move to the solid line position shown in FIG. 2. During this movement the second arm 111 contacts and actuates a switch 116 to complete a circuit and to energize a counter solenoid 117 shown in FIG. 6.
- the counting mechanism is mounted within the supporting frame 18 and includes a pair of spaced sprocket members 118 and 119 rotatably supported on an upper girt member 120 by stud elements 121 and 122, respectively.
- a lower girt 123 supports a similar pair of sprockets 124 and 125 that are rotatably mounted on stud elements 126 and 127, respectively.
- the upper and lower girts 120 and 123 are disposed in spaced relation and are attached to the vertical end members of the supporting frame 18 by means of bolts 128 and nuts 129 (FIG. 6).
- the sprocket members of the counting mechanism are interconnected by an endless link chain 130 and the number of links which said chain contains is equivalent to the number of bobbins loaded into a given container.
- Stud 121 which supports a sprocket 118 is somewhat longer than the other sprocket supporting studs of the counter mechanism and is supported on its outer end by a generally U-shaped support bracket 131 which is situably attached to the upper girt member 120 (FIG. 6).
- Stud 121 supports a ratchet disc 132 for rotation with sprocket 118, a second ratchet disc 133 and an oscillatable actuating member having an upper arm 134 and a diametrically opposed lower arm 135.
- the upper arm 134 includes a pivotable spring biased pawl 136 which is engageable with the teeth of the ratchet disc 132.
- the lower arm is pivotably connected to a lever 136 by means of a link 137 and the lower end of said lever 36 is pivotably attached to a bracket element 138.
- Bracket element 138 extends laterally from and is fixedly at- 7 tached to the solenoid support 139 that is attached to and extends between the upper and lower girts 120 and 123.
- the solenoid plunger is identified in FIG. 6 by numeral 140 and is pivotably attached to lever 136' at a point intermediate its ends as at 141.
- the lower portion of the oscillatable actuating member is provided with an integrally for-med cam element 144 which is adapted to hold the pawl 142 out of engagement with the second ratchet disc 133 and as sprocket 118 is rotated said cam element is moved to a position which allows said pawl to make contact with a tooth of said second ratchet disc 133.
- the chain is caused to move in the direction of the indicating arrow 148 shown in FIG. 6 and must make one complete movement about the four sprockets of the counter mechanism to load the proper number of bobbins into a container 17.
- one of the vertical end members of the supporting frame 18 supports a switch 149 which is closed to complete another circuit to be described by a protruding roller 150 that is attached to one of the links of the chain 130.
- the protruding roller When the first bobbin is loaded into a container the protruding roller is one link beyond contact position with the switch 149. After loading the last bobbin, the chain will have made one complete movement about the four sprockets, and the next increment of movement brings the protruding roller into that position shown in FIG.
- switch 149 energizes and completes a circuit to two different solenoids.
- The'first is identified in FIG. 2 by numeral 152 which has a plunger 153 that is pushed outwardly when this solenoid is energized.
- a first arm 154 of a pivotably mounted' bell crank lever is in contact with the plunger 153 and as the latter is pushed outwardly it pivots said bell crank lever causing a second arm 155 thereof to pivot downwardly.
- This second arm 155 is in contact with a check nut 156 on the linkage rod 99-and the downward movement of said second arm moves said rod-in a like'direction.
- This movement of the linkage rod 99 pivots the double armed lever 100 to a'position to lift the pivotable key 57 out of the transverse slot 53 of the crank' arm '45 thereby causing a cessation of bobbin advancement through the chutes and 'actuation o'f-the plunger member 60.
- the second solenoid which is energized by the closing of switch 149 is identified in FIGS. 4 and 7 by numeral 157 which is attached by means of cap screws 158 to a generally L-shaped support bracket 159.
- This support bracket 159 extends from and is assembled to the vertically extending frame element 39 by means of bolts 160 and nuts 161.
- This solenoids plunger member is depicted by numeral 162 (FIG. 4) and by means of a coil spring 163 it is connected to the upper end of a double armed lever generallyindicated by numeral 164.
- Lever 164 is pivotably mounted intermediate its ends on a stud 165 one end of which is fixedly held in an integrally formed boss 166' that depends from the support bracket 159.
- lever 164 is in contact with the side of a lifting lever 166 (FIGS. 4 and 7) which has one end thereof universally supported on a stud 167 that extends from and which is fixedly attached to the frame element 13 in FIG. 4.
- a coil spring 168 Adjacent that end of the lifting lever 166 opposite the end that is universally attached to stud 165, a coil spring 168 is provided having one end attached to said lifting lever as at 169 and the opposite end (not shown) at any suitable position within the structure of the loader. This spring is arranged to continually urge the lifting lever 166 to a position out of contact with the lifting cam 40 and when solenoid 157 is de-energized said spring is effective in moving said lever to that position.
- the end of the lifting lever adjacent to coil spring 168 has an upwardly directed lifting rod 170 (FIGS. 1 and 7) pivotably attached thereto as at 171.
- the upper end of the rod 170 is pivotably connected to the end of a first arm 172 of a bell crank lever generally indicated by numeral 173.
- This bell crank lever is pivotably supported at one end of a mounting bracket 174 (FIGS. 1 and 7) which is fixedly attached to the upper end of the vertically extending frame element 39.
- Frame element 39 extends above the supporting frame 18 as shown in FIG. 1 and in addition to the mounting bracket 174, it supports a junction box 175 that houses the starting, stopping and jogging switches for manual control of the loader and are shown 'in said loaders circuitry diagram of FIG. 9.
- the second arm of the bell crank lever 173 is depicted in FIGS. 1 and 7 by numeral 176 and'is provided on the end thereof with a laterally extending stud 177.
- One end of a push rod 178 is pivotably mounted on stud 177 and extending therefrom the opposite end is provided with a slotted rod end member 179 which is suitably attached to the upper end of a single armed lever 180.
- the lower end of lever 180 is in hub form and is fixed on one end of a shaft 181 (FIG. 1).
- Shaft 181 traverses the distance between corner element 21 and the arch support 22.
- Shaft 181 is journaled for oscillating movement in aligned bearing members 1 82 and 183 (FIGS.
- a bobbin stacking'arm 184 is fixedly attached at one end to-the shaft181 and at a position approximately midway between bearing members 182 and 183.
- the stacking arm 184 is pivotable with shaft 181 and as shown in FIG. 7i's adapted to be pivoted into and out of a container 17 that is in bobbin loading position.
- the bobbins are caused to be loaded into the container they have a tendency to collect at the lower end due to the angular position of said container on the inclined track and to first fill that area beneath the stacking arm 184. As more bobbins are loaded they pivot the stacking arm upwardly and when it has received its full compliment, said stacking arm is in the intermediate position shown in FIG. 7. This arm is effective in controlling the positioning of the bobbins as they are loaded.
- the first of these solenoids 152 is effective upon the bobbin advancing and loading elements so as to cause a cessation thereof.
- the second solenoid 157 is effective through lever 164 in moving the lifting arm 166 to a position to be contacted by the lifting cam 40.
- the rotary motion of the lifting cam causes the lifting arm to pivot upwardly causing the bell crank lever 173 to pivot in a clockwise direction, as seen in FIG. 7, by means of the lifting rod 17 0.
- This motion moves the push rod 178 in the direction of the indicating arrow 185 in FIG. 7 and pivots the single armed lever 180 in a clockwise direction or from the intermediate position shown to that position shown mak ing contact with a switch 186.
- switch 186 completes a circuit to and energizes an indexing solenoid that is depicted in FIGS. 7 and 8 by numeral 187.
- the indexing solenoid is effective upon indexing linkage, which will be .more fully described hereinafter, in releasing a full container from loading position and to permit the next empty container to move into said loading position.
- the indexing of a full container is accomplished'during two revolutions of said cam. After the first revolution the container is released and moves a short distance to a position where it is temporarily held by a part of the indexing linkage and after the second revolution it is released to move along the inclined track while the empty container following is moving into loading position.
- a dash pot 188 (FIGS. 1 and 7) is provided.
- This dash pot is in the form of an air cylinder which is attached at one end to the mounting bracket the end of the push rod 178.
- portion of the supporting frame immediately adjacent to the inclined track includes a vertically extending wall 190. This wall extends upwardly from rail member 11 immediately adjacent to the container loading position on the inclined track.
- Apair of electrically controlled switches 191 and 192 that are disposed in spaced relation are supported by the wall 190 with the contact elements 193 and 194 thereof arranged so as to be in contact with the containers on the inclined track. These switches are connected in parallel and either one or both must be closed to keep the loaders driving motor 26 from being shut off.
- both switches 191 and 192 are closed. As a container leaves the loading position contact with switch 192 is lost; however the empty container following closes the latter switch before the loaded container moves on to lose contact with switch 191. When the last container is loaded and caused to be indexed for movement away from the loading position, contact is lost with both switches resulting in power to the loader being shutoff. In this event an indicating light 195 is lit to indicatea cessation of bobbin loading and this light is diagrammatically shown in FIG. 9 of the drawing.
- the door 82 in the bottom of the container is provided with pins 196 on each side thereof which protrude outwardly through appropriate slots in the sides of said container.
- pins 196 are caused to move along the upper surface of cams 83 and 84 to open said door a suflicient distance to permit the loading of bobbins 78 therein.
- closing cams 197 and 198 which are fixedly attached to the corner element 21 and the arch support 22, respectively, (FIGS. 1 and 3).
- skid plate 199 is provided. This skid plate extends between the rail members 11 and 12 adjacent to gate members and 81 and at a height which places it in close proximity with the bottom of a container. The door 82 as it closes is pushed beneath the last loaded bobbin and the container is then allowed to move along the track to a pick up position.
- the indexing means for releasing a full container from bobbin loading position and for permitting the receiving of the following container int-o loading position will now be described.
- Each of the indexing elements includes a support bracket having integrally formed hubs at the upper and lower extremities thereof.
- One of these support brackets is fixedly attached to the arch support 22 and is identified by numeral 202 (FIG. 8).
- the other of these support brackets is depicted by numeral 203 and is fixedly attached to the corner element 21 of the supporting frame 18.
- Each of the support bracket 202 and 203 supports for rot-ay movement in their upper hubs, horizontally disposed shafts 204 and 205, respectively. These shafts 204 and 205 extend beyond the ends of their respective hubs and each supports in spaced relation a pair of indexing fingers or rotatable spoked members.

- the control relay 259 when energized; de-energizes the indicator light and energizes a motor controller 260. This motor controller then starts the motor 26 through the motor contacts 248 and energizes the solenoid circuit.
- the switch 258 shown in FIG. 9 is illustrated in FIGS. 2 and 4 as being attached adjacent one end of the pitman 43.
- the pitman is of two piece construction with one portion being slidable inside of the other in the event it is subjected to abnormal pressure such as a jam or the like. In this event the switch is closed by a lug 261 fixedly positioned on the pitman and power to the loader is automatically discontinued.
- a plurality of empty containers 17 can be supported by the inclined track and so disposed as to move toward bobbin loading position through the force of gravity. After a given container has received its full compliment of bobbins, it is released by the indexing arrangement and will move away from loading position to the lower end of the track where it is ready for pickup and placement upon a donning machine.
- switch 191 is opened to discontinue further advancement and loading of the bobbins and completes the circuit to the indicating light 195 and signifies to an operator that the power is still on but the loader is not operating.
