T0 aZZ tlf/7mm, n' may concern: f

Be itknown that I, BAMBL SCANLAN, citizen of the United States. residing in the city of St. Louis and Sttte of Missouri, have invented a new and useful Rope-Machine. of which the oliowing :i speciicnion.

This invention relates to im rcvenients in rope machines.

In certain machines it is useful. end indeed often. necessary that, the machine. he en tomatically stepped when the 'feeding oit' materizil being operated upon to the machine for any reason is interrupted. Especially is this true in zi sli-tending machine uscci in windingI rope. "W hen one srenri ot Wire or other material fed to the machine in rope Winding becomes broken, if the machine continues to operate n defective product will result. Therefore the machine should he 'brought to un immediate stop, when a Wire or corri breaks.

An objectoi the present invention is to provide :s means in cornhination with stranding or ropewincling machines, of automatic mechanism which is actuated upon the interruption of the normal feed of the rope making material effectively to stop the operation of the machine so as to prevent the profilietion of defective rope wih broken wires or cords. anni to enable the operator to ineke such repairs :is are necessary to permit the continuous feed of the rope nnierial to the Winding head of the machine cnil which mechanism will :also he operable to stop the nmchine.y should any of the Wires or corals become loose so es to produce rope where each of the Wires or cords have a. uniform tension.

To this and other obvious ends7 have (iesigned, combined and arranged kthe Seremi cooperating parts hereinafter shown, illustrated and embraced wit-hin the scope of the appended claims.

tively to control the clutch mechanism. The shaft 1 has' rigidly fixed thereto a band wheel 13 which is encircled by a band 414 the ends of which are securedto one arm of the bell crank lever 15, said 'bell crank lever 15 being pivoted to a suitable support 16. A second Huid motor B is' provided for actun ating said lever 15 and thereby. controlling the band 14 encircling the wheel13, which parts constitute a band brake for releasing and locking thel shaft 1. The motor B comprises a cylinder 17 in which is operatively mounted a piston which carries a piston rod 18, which is pivoted to one arm of the lever 15. A spring 19, encircles'the piston rod 18 and holds the bra-ke mechanism normally in admitted through the passage 20, the piston mounted in the cylinder 17 is driven to the right (Fig.` l), thereby tightening the band 14 about the band wheel 13, effectively to lock the shaft 1.

The pressure in the passages 11, 12 and 20 is normallycontrolled by means of a valve C which is interposed between said passages and the main supply passage 21, which communicates with any suitable source of fluid pressure supply. In starting the operation of the machine the clutch is set, bycommunicating the passages 21 andllthrough the valve C, which throws the piston in the cylinder 10 to the left (Fig. 1), in which position it remains until vpressure is introduced into the passage 12.

In machines of the type in which I have illustrated the embodiment of myvjnvention, the shaft 1 carries a series of rings 22, (only one of which is illustrated for the purpose of convenience), each of which rings is supported by supporting roller 23 mounted in the base D of the machine. The wires or liber cords are carried forward from reelsv and are passed through slots in the rings 22% arranged adjacent to the peripheries there of,"atequidistant points on their circumfer-- ences are fed forward into the winding headfE. The mechanism for automatically control'- ling the motors A and B constitutes a part of my present invention and as illustrated in the embodiment shown comprises, a plate 24 which is provided with a series of equidistant slots 25 arranged in its periphery; the number of slots being the same as the number of wires or cords being fed to the winding head E. The plate 24 is rigid on the shaft 1 and isi positioned intermediate the forward ring andthe winding head E, as

As Huid pressure is clearly appears by reference to Fig. 1 of the drawings. The twisting head E may be of any of the usual types and it will be understood that said twisting head is adapted to wind or twist the cords or wires to form a rope. The cords or wires are drawn from the reels or bobbins and nre-guided or fed to .the-twisting head by the plates 24 and

rollers

31 and 32. Each of the slots 25 has a correspqnding radial bore 26 in which is mounted a tripping pin 27, said pin 27 being slidalgle radially of the plate 24 and the movement of which is limited by a Cotter pin 28 doperating .in a slot 29 formed in the pla 24. At either side of the plate 24 are laiges 30 which carry a series 'ofroller suppor s 31 in which are operatively mounted rollers 32, the arrangement being such that the vinner series of rollers 32 extend.'

slightly beyond the periphery of the plate 24and the outer series of rollers 32 being,

slightly within the periphery of said plate 24. As the wires or cords 33 are drawn forward they are passed under the inner rollers 432 and through the slots 25 and over the outer rollers 32, to the twisting head E, and I in normal feeding are held taut, thereby retaining the pins 27 within the periphery of f the plate 24 in the manner illustrated in Fig. 4. Should any one of the wires vor cords as they are being fed tothe twisting tical position and carriers atl one side therej of, a roller 37 which normally bears against the upper face of the lever 38. one endof whiclf lever 38,-'is pivotgd in the lug 39v mounted on the upper'face of the stand 36. The lever 38 normally rests in a horizontal t, position and is provided, with a notch 4() yadjacent 'to its free endfwhich constitutes L a latch for one end of the lever 41 said lever .'41 having connected to its opposite end, one

end of a tractile spring 42,y which spring is secured to the upperface of the stand 36 in 4such a manner that when the forward end of the lever 41 is released it'will be actuated to the position shown in dotted lines in Fig. 7 The lever 38 operates in a guide 38a and it will be apl arent "that as the lever 34 is thrownl to the oblique position, shown in Fig. 2 in dotted line, by a tripping pin 27 that the free Aend of thelever 38 will be depressed suiiciently to unlatchthe lever 41. The lever 41 is secured tothe upper part of 'the valve plug43; said'plug 43 being operatively mounted in the valve casef44; Y'The actuating Huid supply passage 4:5vr enters the' rope twisting mechanism vdrivenv by said shaft, a pulley' loosely mounted upon said shaft for -driving said shaft, releasable mechanism for locking said pulley in engagement with said shaft, and an actuator' for releasing said last-named mechanism to enable said pulleyto turn independently of said shaft, of a brake for stopping said shaft when said pulley is released from said shaft, automatic mechanism for electingthe release of said pulley from said shaft as an incident t`o the breaking offanyof the wires being twisted, and automatic means for setting said brake concurrently with the release of said pulley, electively to stop said shaft, substantially as specified.
