A 1 driven rails 9 and 8 rehuh :1HE shmvl Viv Stans. Motion is imparted to the driving roll or capstan 9 by means of a pair of spurgears 13 and let, one carried by the roll or capstan and the other carried by a stub- Shaft 15 mounted in one of the members of the pull-down frame. This Stub-shaft, also carries a beveled-gear 1G meshing with a similar beveledlgear 17, fixed to or formed on theend of the tubular iahaft 3 journaled in the upright Lt and to which tubular shaft motion is imparted by any .suitable means` such for instance1 as a belt. pulley 1S mounted on the end thereof, and by meana of which the desired speed or pull-down force is Agiven to the capstanS, the. driven capstan being rotated by its frietional engagement with the bodily shiftable roll and the rope. Motion may be imparted to the pulley 1S by a belt (net shown) in engagement with a pulley (not Shown) carried by the drivingr shaft, (not shown) which at its opposite end earries the fast and loose pulleys o and The speed of rotation of the pulley 18 relative to that of the pulley 12 i@ such that the product is taken up by the liier substantially as fast as it is passed4 through the pull-down by the pulley lo. `During the travel of the rope around the capetansA` the pull-down frame rotated to twist Such rope in the manner just, deScribcd, so that during the twistingr of the rope the desired pull-down force ia given thereto to regulate the number of twists per foot in the finished product. To obtain an accurate bearing or grip of the rope on the capstans, there is located between them a bodily movable roll 20, and

-the rope or line by straddling this roll 2O is carried nearly around the capstans causing;r a greater grip on the same. This roll is shown as a hollow cylinder and is mounted loosely, that iS, with sufficient; clearance on a xed shaft Q1 extending aerol the frame 2, to enable the roll to properly pe1- form its work, or, if preferred, thie Shaft could be loosely mounted in the members of frame 22, thereby allowing the roll to have a gripping effect 011 the cord or rope as it ia drawn around the caliistans, and also -allowing said roll to be pushed away from the capstans when a lump or knot in the rope passes. By forming the looae roll hollow it is lightened and the force of centrifugal action iS reducfgd. The roll in preferably sufficiently small rclat1vely to the capstans So that the cord or rope which passes partly around the capatans and atraddles this roll will under draft cause the roll to become wedged between the capa-tails and bear hard upon the cord or rope, and in order to secure a superior wedging effect` at least one-half of the roll` when regarded aa` divided diametrically, yQhould be included within the Space bounded by the pcripheril i of the capstanrs, ay plane embracingr the axes ot the latter, and a plane tangential to their (wh ich resists peripheries. By so proportioning and o1'- ganizing the eapstans and rolls to secure this relation, a wedging effect is produced draft upon the rope7 sueh wedging effect being obviously superior to a simple pinchingl of the rope. This improved pull-down, and that illustrated in my contemporaneoubly pending application hereinbefore referred to, is believed to accomplish what has never before been accom1' li hed in rope making machinery, namely, the absolutely accurate registoring of the twisted strand or rope7 that is, the uniform pulling down of exactly the same extent of twisted rope for every repetition of a speeihed number of rotational of the pull-down capstans, and for every eorre- `spending number of twieting rotations. This is ofthe utmost importance lsince it insures absolute uniformity in the product as to number of twists per unit of length, as to length of measurement governed by known time and machine elemente and astto character and weight. Obviously a pulldown operating' with such accuracy as does the present one insures unvarying etfccts in the treatment of the strands preparatory to their reception at the pull-down mechanism both prior to and including the twisting together of the stranda. 'l `urther1nore, an important point to be noted is that the accurate registry in the operation of this pulldown device, does not at all depend upon the forward draft of the rope,that ia, a draft in the direction of the ta lie-up mechanism; the pull-down would continue to opcrate, acchrately registering, if there were no Such forward draft whatever on theI rope; hence a take-up mechanism employed in connection with this pull-down is merely required to perform the simple functions that its name implies, namely, caring` for the finished product as it arrives: so that the additional function heretofore' required of the take-up mefirhaniam, namely, thc exertion of a foree to maintain a powerful forward draft on the rope aa it emerges from the pulldown, is entirely elin'linatcd.

The grooves in the capstans or rolls which receive the rope as it passes around such capetans, control and guide the rope so as to maintain it; in proper position on the Capstana. while at the same time the cl'iaracter of the grooves inaures the projection ot' the rope for the engagement tlwrewith of the bodily movable roll. lhe central or bodily movable roll 20. in the present, instance, is lahown provided with guide-flanges at the outer laides of the pullfdown rolls or cap` stam, and is also yhewn provided with ,frroovw`r Q- which prevent. the flattening; of thil rope. The rope is preferably doubled in the pull-down. that is, brought back and ima-sed a eeeffnd time around the capstafns and thi-nti' over the bodily movable roll,

c From the foregoing organization it will be seen that the movement Yot' the worm shaft, and therefore ot the carriage, is determined by the rope being wound as it is taken up on its drinn ,so that the rope may be wound en the drum without flanges at the ends thereof. as shown in Fig. 5. that is to say. it may be wound in .te form of crossed helices in a similar manner to that shown and described in the patent to'\Vardwell,

Reissue No. 11.8.76 dated September 18,!

laut). From this it will be seen that by the improved mechanism shown and described a cop wound in the manner just stated may be obtained.

During the: operation of the machine the rope is twisted as it passes through the shaft 5 to the pull-downlcapstans. trom thence it passes through the bore otl the shaft t5 around the guide-rolls 30 and 3l to the flier tube. through such tube to the guide-rolls 3;). and and through the shaftQS tothe guideroll Ill, and from thence to the carriage, around thc shcave til trom which the rope passes to the drum. nother twist is given to the rope at a point intermediate the rolls 33 and 3l and this twist will be a second twist.

In order to stop the machine instantaneously on the breakage ot the rope or cord. I provide an improved mechanism, one partot' which comprises a lshil'table member shown iu the t'orm otl a yoke To pivoted to the hub ot the llier head Ll'. and normally held down againstV the head by the engagement ot' the rope with tbe' t'ree end thereol" as it passes lrom the `guide-roll 230 lo the roll 31. Should the ropt` or cord break this shil'table member will swingout by centrifugal l'orcc and carry its tree end into position to engage a projet'A tion or linger Tl pivotcd on the upright Il and which linger control.`l the .shitting of the belt from the tast pulley to the loos(` pulley and the braking ol' the tlier.v

.\ suitable belt shitting mechanism mounted on the trame-work and comprisesy a belt shit'ter T5 actuated by a suitable hand lever Tt to shil't the driving. belt trom the loose pulley i to the tast pulley l1. it being automatically returned by a suitable spring T7 to sltil't the belt back Vtroni the tast pulley to the loose pulley. ltor maintaining the, belt shit'ler in its shifted positiony and against the action of its spring` a suitable spring vactuated bolt is provided comprising a rod T8 adapted to project. into an openingr 7) insthe beltI shil'ter. 'l`his rod is connected at its upper end with the pivoted linger or projection 7l which as herembefore stated -1s in position to intercept'y the yoke when it 1s thrown out by centrifugal force on the breakage ot' the cord. From the foregoing it will be seen that the belt shifter having been xshifted to carry the belt. to the 'last'l pulley and locked in sus-h positiven should t the rope or cord break, the yoke, by centrifl ugal force, will be thrown outward audien- Il gage theifinger 71, move it downward fand "so raise the boltfrom the belt shifter, where-- [upon the spring will throw such shifter. which will move the belt from the fast to the l loose pulley, the transmission of power to ithe winding mechanism being thus interi cepted. The finger 71 may also be shifted by i a suitable hand lever 25 pivoted on the machine and normally held in its inoperative Pposition by a spring'. l Thilo the mechanism just described will l interfere with the transmission of power to the winding mechanism, it is desirable that such winding mechanism be1 instantaneously l stopped on the breakage of the cord or rope, l and for this purpose a suitable brake is provided comprising a brake band 90 in position to engage the periphery of one ot' the l heads. as the head 2T ot' the tlier. This band i 9() connected by a pivote-d artn 91 and lever 92 with the belt shifter T5 in such malll ner that when the belt is shit'ted to the fast I pulley the friction band will be held out of )engagement with the head. but when the bolt has been withdrawn from the opening in lthe belt shit'ter by the engagement ot' the Il yoke with the finger. the return o't` the belt shifter under the action ot its springwvill throw the brake band 90 into engagement t with the head and stop the rotary movement l of the flier substantially instant'aneously.

l It is to be understood that this windingr l mechanism may be used t'or other purposes lt'han winding rope or cord. and therefore l such term rope .or cord as used herein I and in the claims. is to be interpreted to in elude any article capable ot' being wound y with this organization of mechanism,
