STOP MOTION.

Application filed July 18, 1922.

T all 'whom 'it may Concern:

Be it known that l, VINCENT VANTE, a

I citizen of the United States, residing at specification.

My invention relates to stop motions for gill boXes and has tor its essential objects the detect-ion ot' any slack or clogging of the travelingA slivers and the stopping of the mechanism when event occurs; adaptability for use without incorporation into the ma` chine and without reconstruction of the latter; portability; and certainty and speed ciA operation.

To the above ends essentially my invention consists in suoli parts and in suoli combinations of parts as fall within the scope of the appended claims.

on lines 12-12 and 13-13 respectively of Figure l1.

Like reference characters indicate like parts throughout the views.

In the drawings 17 represents the trame, 18 the driving shait, 19 the pulleys, 2O the belt, 2l the fork, 22 the shitting rod, 23 the bell crank lever, and 24 the hand operating rod ot a gill box of any usual or pre- Jferred construction.

26 is the disk, and 27 the peripherally slidable strap of an eccentric 28 which is mounted on the driving shaft. An inclined reciprocating finger 80 is fast to the strap. Below the latter is a portable frame comprising a horizontal strip or plate 32 having a depending lateral flange Bel. The strip 32 has an oblong slot 35 with a lateral recess 36 forming a resultant shoulder 37, and is sua orted at its ends b f divero'ine leo's 88 C J C resting upon the floor 39. An oblong plate 40 is attached to the rear of the frame by Ibolts al passing through the liange 8a and is spaced trom the latter by collars 42 tornr ing a resultant oblong opening 473. Fast to the rear face of the plate l0 midway .its length is an ear or lug having a vertical oblong slot i6 in its upper portion, below which is fast an outwardly extending horizontally disposed rod i8 carrying an antifriction roller or bearing sleeve tor the finger 30. `Fastened by bolts 511: to the plate 32 is a depending tlat rod 56 bent at its lower end to form a U shaped portion 5T extended to form an upright resilient arm 58 whose upper portion 59 projects through the slot 35 and forms an operating handle in the path oit a finger 60 extending trom the shifting fork 2l.

Plates 61 are clamped to opposite tacos of the arm 58 by screws 63, one ot which plates has a guide pin 6ft registering loosely in a longitudinal slot 66 in a flat rod 6T to whose opposite end is pivoted by a pin 68 a. lever69 which passes through a peripheral slot 70 in a. cylindrical switch casing` or housing 7l. The lever is pivoted intermediate its length on a pin 73 in the end walls of the housing. Fast to one of these walls is a strap 7 5 embracing the rod 56 fixing the housing to the latter. A wire spring 77 has one end attached to the side wall of the housing by a screw 78 while its opposite end is fastened to the lever 69 by a bent end 79 passing through a perforation 80. An insulating block 82 is fastened by screws 83 to the lower portion of the housing wherein is a hole 84, registering with a vertical passage 85 in the block, and with a hole 86 in a metal plate 87 fastened by a screw 88 to the top of the block. Integral with the plate is an inclined contact arm 89 in the path of the lever 69. There is a binding screw 91 in the plate 87 and like screw 92 in a housing which .respectively engage a conductor 94 which passes through the holes 84, 85, and 86, and a conductor 95. The arms 69 and 89 constitute a switch indicated generally by 96.

Loose on a pin 97 in the flange 34 at one side of the ear 45 is an angular lever com* prising a body 99 and arms 100 and 101. The pin 97 passes loosely through a vertical oblong opening 103 in the flange 34 and having a head 104 upon one end engaging the lever7 and a disk or nut 105 upon the other end. A helical spring. 107 on the pin has one end pressing against the flange 34 and the other against the disk 105. By this construction the angular lever has not only pivotal movement transversely of the pin. but is yielding longitudinally thereof. .On the arm 100 is a lateral spacing plate 109. To the arm 101 is loosely pivoted by a pin 110 the upper end of a depending flat link 111 having near its lower end a longitudinal series of holes 113 adapted to receive a threaded pivot pin 115 inthe outer end of an armature lever 117. On the pin is a, nut 118.

The lever 117 passes through an opening 119 in an end wall of a wooden box or casing 1217 and through lateral openings 123 in a housing 125 fastened by a screw 126 to a wooden cross piece 127 in the box top. The lever 117 is pivoted on a pin 129 fast in the housing and has intermediate the pivotal point and its free end a laterally projecting portion 130 adapted to register with the cores 132 of a magnet 133 whose spools 134 are wound from the wire 95. passing through an opening 135 in the box. Upon the end of the armature lever is a counterweight 1.36 adjustable by a set screw 137. Extending from the spools of the magnet through the opening 135 is a conductor 139 leading to a battery orother source of electrical power, in this instance to a. transformer 141 connected by wires 142 and 143 to the wires 144 and 145 respectively of a power circuit.

Resting on'the body 17 of the machine is a frame work 148 comprising open metallic vertical end pieces or frames 150 with a top cross bar 152 and bottom cross bars 154. Each framek is filled with a wall or plate 156 of insulating material covered by hollow or flanged wooden sheathing strips 158 registering in the frames 150 and attached to the insulating strips by screws or bolts 160. Transversely disposed metal strips or plates 162 are fastened, one above the other, to the inner face of each wall 156, and each plate has a longitudinal series of holes 164 regis tering with series of holes 165 in the walls. Mounted in the holes 164 and 165 are rock shafts 166 having in their ends locl; pins 168 toy whose ends are attached helical springs 169 whose upper ends are fastened to pins 170 in the walls 156 above the shafts. Each shaft carries a guide 171 for a length of sliver 172 passing from the usual supply balls to the winding roll of the gill box: the balls and roll are not shown. Each sliver comprises the usual mass of threads. Each guide comprises a pair of legs 174 formed from bent wire whose free ends are fast to the rock shafts 166 and inclined upwardly some distance and thence downwardly at an incline as at 175 and terminate in horizontal loops 176. These guides are completed by troughs 177 bent up from sheet Vmetal comprising downwardly inclined bottoms 178 and vertical sides `17 9. Integral sleeves 180 and 181 on the bottoms and sides respectively embrace the loops 176 and arm portions 175. The slivers pass through the trough portions of the members171 and by their weight in passing overcome the resist ance of springs 169 and maintain the members 171 against longitudinally disposed stop rods 184 fixed to the frames 150 above the planes of the shafts 166 by screws or rivets 185. lf however any sliver 172 becomes broken or slack its guide is raised by its spring 169 until it engages a contact rod 187. There is one metallic contact rod fast in walls 156 above each series of shafts 166 in a horizont-al plane above the stop rods 184. A longitudinally split removable tube 189 of rubber or insulating material is sometimes temporarily employed on the rods 187. Such a tube is shown in Figure 11. The ends of the rods 187 proiect slightly beyond the insulating walls and are there connected by electric wires 191. A binding screw 193 of each plate 162 passes through the wall 156 and carries a nut 194 to clamp a wire 196 which thus electrically connects the series One ing in its recess 36 `and held against the ac-' tion of its spring loop portion 57 by the shoulder 87. This lever is also in Contact with the finger upon the shifting fork 21 which is at this time engaging the belt on the fast pulley, and the plunger finger 30 is continuously reciprocating towards and from lever 59 by virtue of the eccentric 30. The spacer 109 is normally in the position shown in Figure6 so that while the machine is running normally the spacer is out of the path of the reciprocating finger' 30.

Vhen, however, the stop motion acts, as will be later described, the spacer 109 is swung forwardly into the path of the linger 30 as shown in Figure 9 and the nger in its next advance strikes the side of the laterally yielding spacer 109, which is now abutting against. the lever 59, and pushes the latter out of its seat. Thereupon the lever is forcibly impelled by the action of its spring 57 against the finger 60 which shifts thel fork 21 to the loose pulley, as shown in Figure 2, thus stopping the machine.

The spacer 109 is thrown in operative stopping position thus. lVhen one of the cables or slivers 172 in its passage to the winding roll becomes slack so as to occasion clogging or folding of the sliver its guide 171, released from the weight of the sliver, is by its spring 169 forced upwardly so that its legs 174: contact with its adjacent bar 187, thus closing the electric circuit. The current then passes through the conductor 191, rod 187, arms 1741, rock shaft 166, strip 162, wires 196, 94, and through the closed switch 96 wherein the arms 69 and 89 are in contact with each other. The current passes, therefore, through the plate 87, arms 89 and 69, pin 78, housing 71, and wires 95 and 139. The current energizes the magnet 183 to tilt the lever 117, which depresses the link 111 and lever arm 101 and swings the spacer 109 into operating position.

The instant the lever 59 is unseated and swings to its outward limit the circuit is broken by the separation` of the arm 69 from the arm 89 as shown in Figure 6.

The particular number of guides 171 in use at any given time is determined by the number of strands desired to be wound from the supply rolls. Therefore at times one or more horizontal rows of guides are not in use. In such case the bar 187 abo-ve the line of idle guides has manually applied thereto an insulating tube 189 against which the vacant arms of t-he guides normally rest so that the circuit is not closed thereby.
