Application filed July 31, 1923, Serial N'O. 654,961. vv'Relitti/ved March `2O, 1928.

This invention relates to feeding mechanism,V and more'particularly to a mechanism for feeding a strand into a receiver.

In the manufacture Oi" rubber covered wire, where a coie ofwire is coatedwith a rubber Compound which is later to be vulcanil 1Ze`d it is necessary, in the stage before vut,

canization, to preserve the comparatively plastic coating from distortion whichV would deleteriously atl'ectits insulative properties. This may be accon'iplished by coiling the y -coated strand in superimposed layers, each convolution of which fits smoothly against the ,adj acent ones, and surrounding` and sup-` porting it with powdered soapstone to preventdefoi-mation ort the coating and adhesion O15-.adjacent turns. y AnA object of the present invention is to improve and'sim'plity a device for storing a strand.

Another object is to coil a strand in a re-A ceiver by regulating the rotary and lateral movements of a receiver.

' An apparatus made in accordance with they invention may comprisea rotatable storage pan mounted upon a movable carriage which is operated reciprocally at a predetermined speed to allow'strand.y which is fed into the pan ata constant speed, to be coiled therein in regiilarsuperimposed layers.v

These and other features oflthe invention not specifically mentioned will appear from the following description and the accompanying drawings, in which:

Referring to the-fdrawings in detail, .a base plate 10, which m-aybeof'cast metal, has pariv allel-ridges11 on'its 'upper surface. running Alongitudinally'thereof to torina track for a carriageyshown: generally at 12, which. moves reciprocally thereonduring tlieo'pe'ration' oi themachine; Aft eitherend of this base platel arefaflixed'-'uprights 14 afndvl respectively, `whilea third upright `18 ycarries a cap'stan 38 which receives the wire 1t from a covering yrEEDING iviEcrIiLiNisr/i.r

Extending from the rear of the carriage is an arm 90 which Carries a hopper 92 in which powdered soapstone may be placed and in which a brush 94 is'rotatably mount# led over a slot96 in the bottom of the hopper. vA friction drive wheel 98.is rotatably mountl, ed on the lower end of an arm 97, pivote-d lat V93, the'upper end of this arm being held between a screw '89 and a spring 85. A pulley 8l, integral with wheel 98, carries a belt 77 which, operating around idlers 73 and pulley 69, transmits the motion of wheel 98 to the shaft of the brush 94. The idlers 73 are mounted on either side of a pivoted weight v65 which'acts to keep the belt 77 taut at all times.

It will befnoted that the pulley 69 is fixed upon an aiin from post 90, while the hopper is pivotally mounted upon a sleeve 6l which V `lits over a post 57 integral with arm 90.

A pin 5l set in post 57 and riding in a slot 47 Vin the sleeve 6l, serves to limit the rotationrof the sleeve, while a locking pin 4l, being forced inward by spring 37, fits into a Adepression in post 57 when the hopper is in position for operation to lock the sleeve in place. In order to permit the hopper to swing on its pivot, the shaft of the pulley 69 is splined at one end and a projection from 'the brush shaft fits into it as shown at 33,

thus permitting` the separationof these parts when thehopper isk swung away from the .pan and their union when it is swung back.

The operation of the machine is as fol- A'strand ofcoated wire is brought from a coating machine (not shown), is given a fewturns around the capstan 38, and its l end is laidiii the pan 80, the bottom of which l vvis irst covered with powdered soapstone to form a seating for the firstlayer of wire. The carriage l2 should be at either the outer or the `inner limit of its movement `when starting an operation so as to make the lirst laye-r of strand continuous across the bottom of the pan. i The machine is then ready to be operated by starting the mechanismwvhich operates ythe drive wheel 22. Thiscauses the capstan 38 to revolve and feed Awire into the pan and also, acting through the variable speed drive cones 40 and 42 and bevel gears 50 and 52., causes the pan 80 to be' rotated by causing the rotation of the wheel 56. Table 76, resting on. the other wheel 60, causes thi'swheel to rotate also, and with it the bushing 62 which is integral with it. The screw thread in this bushing acting in conjunction with the dog` 86 in the manner pre-` viously described, causes the carriage vto be rolled back and forth on the base l0.

l/Vhccl 56 remains lin the saine position on the shaft 54 at all times, but wheel 60, being integral with the bushing, moves laterally with the carriage, and it will be noted that when the carriage is at the. rightfhand limit of its travel, the whe-el 56 is actingy nearv the periphery of the table, while at the other limit of its travel the'reverse is true. The peripheral speed of wheel`56 is regulated by means' of the variable speed cones 46 and 42 so as to be the saine as the speed of the coated wire as it leaves'the 'capstain and a change of the speed ofthe drive wheel V56 necessarily causes a corresponding change in the rate of rotation of the screw `64 which is integral with driven wheel 60.

T he wheel 60 being driven by the table will be rotated slowly when wheel 56 is near the periphery of the table and the table is beii'igil rotated slowly; and rapidly when it is near the center, since the table is then being swiftly rotated by ywheel 56. The mean rate of rotation Vof wheel 6() may be increased by loosening set screwy l5 and moving the wheel along the bushing toward the periphery of the table and decreased by moving it toward the center. ment is for increasingor decreasing` the lead This adjustf for dilferent sizesy of-strand. The result Ais i clear that when a strand ot wire is feeding into the pan near its periphery, the pan is operating at a proper speed to receive it and is slowly moved laterallyl by the action of the dog 86 in the screw thread 64, vsince` the turns are large here and each one requires a comparatively large amount of strand; while when they strand is feeding into the pan near its center, the pan is.. still ro-` tating at the properspeed to receive it, but

has a faster lateral movement which is neces-A sary since hei'e the turns are small and require a `comparatively small amountl of strand per turn.

When thel carriage reaches either its outer` f or its inner limit, the wheel 98 rides up on one of the rotating driving membersv 70, being held in Contact lrewith by the spring 85, and, acting through the pulley 81 i i and the belt 77, causesthe brush 94 to rotateV yand deposit a quantity of powdered soapstone into the rotating pan, forming a layer of soapstone over each layer of ,wire as it is completed. As soon as the advance of the carriage moves the wheel`98 ofi' the driving member 70, the brush ceasesto'rotate until the advance of the carriage brings the wheel 7 0 into contact with the other driving member, when it is again rotated. The positions of the driving members 70 are adjustable on their shaft, by means of set screws 29,y to permit regulation of the time at which they shall engage and release wheel 98.

This intermittent deposit of soapstone givesa very desirable seating for the wire and allows operation of the device at a high rate of speed.
