Specification of Letters Patent.

Patented Aug. 20, 1907.

Application filed July 3,1905. Serial No. 268,134.

To all whom it may concern:

Be it known that 1, CHARLES W. SPoNsEL, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Rope-Laying Machines, of which the following is a specification.

This invention relates to rope-making and analogous machinery, and has for its principal object the provisionof means for so controlling the tension of the various strands that unevenness in the lay will be entirely avoided.

In the prior art of rope or cordage manufacture, difficulty frequently arises in the proper twisting of the strands, and frequent variations in the lay result, so that one part will be of the required degree of twist, while another part will be loosely connected, thus impairing the strength of the Cordage and producing imperfect work.

It is important in the class of work for which the in vention is designed to apply. equal tension to each strand as the cord or rope is being formed, to indicate automatically the degree of tension applied, and to regulate automatically the tension-devices, so that they will always operate in the same way and with the same degree of pressure upon the strands being made into a rope, and that too, whether the bobbins carried by the fliers be filled or partially filled.

To accomplish these results in a reliable and accu rate manner is another object of the present invention, which includes regulatable tension or pressure-devices and their correlated elements, so proportioned and ar ranged, that the strand from each bobbin will have applied to it a pressure suflicient to cause the cord or rope produced to be of homogeneous twist throughout, and so that the pressure applied to one strand will be exactly equal to that applied to each of the other strands of the series.

A further object of the invention is the provision of means for automatically governing the passage of the strands from the bobbins, said means including a brake and devices for controlling the same, so that whether the bobbin be filled, or partially filled, the strand therefrom will always be under the same degree of tension and each strand will be in like pressure-condition, as the cord of rope is formed from the series of strands, whereby an even lay is produced and a rope or cord having the same homogeneous degree of twist is the result.

A further object of the invention is the provision in cordage machinery, of means for automatically detecting variations in the lay of the strands, and for automatically correcting defects in such lay.

A further object of the invention is the provision of spring scales for indicating the degree of pressure applied to each strand.

A further object of the invention is the provision in connection with the pressure-indicating or tension-de vices of a follower in engagement with the coil on the reel or bobbin.

A further objpct of the invention is the provision of a spring-actuated brake, operating to govern the torque required to cause rotation of the bobbin as the strand leaves the same.

Other objects of the invention will be set forth in the following description.

In the accompanying drawings, Figure 1 is a plan view of rope-laying machinery embodying the features of myinvention, the vertical shaft being in section on line a-a: of Fig. 2. Fig. 2 is a view in elevation, the spiders being broken away, and one of the fliers and its bobbin being illustrated. Fig. 3 is a side elevation. Fig. 4 is an enlarged detail view of the brakecontrolling mechanism. Fig. 5 is an enlarged view' illustrating part of one of the fliers, an arm of one of the spiders, and the tension-indicating and controllingmechanism out of operative position. Fig. 6 is an enlarged detail view similar to Fig. 5, showing the tension-indicating and controlling-mechanism in operative position. Fig. 7 is a plan view of the parts illustrated in Fig. 5. Fig. 8 is a plan view of an arm of one of the fliers, showing the movable steps or plungers for controlling the operation of the compensating mechanism. Fig. 9 is a longitudinal vertical section on line 99 of Fig. 8, the stops or plungers being in elevation. Fig. 10 is a detail partially in section of the brake mechanism. Fig. 11 is a detail in longitudinal vertical section, taken on line 1111 of Fig. 7, of the compensating mechanism. Fig. 12 is a detail in longitudinal vertical section of the conical head, and parts cooperating therewith in laying the strands into a rope, the driving-gear and its shaft being in elevation. Fig. 13 is a sectional detail on

line

13, 13 of Fig. 4. Fig. 14 is an enlarged longitudinally-(livided sectional view of the compensating mechanism taken on

line

14, 14 of Fig. 5. Fig. 15 is an enlarged plan view of the compensating mechanism, parts being broken away. Fig. 16 is a section on line a-a of Fig. 4. Fig. 17 is a section on line bb of Fig. 13, and Fig. 18 is a section on line cc of Fig. 3. 7

Like numerals designate similar parts throughout the several views.

Referring to the drawings, the numeral 1 designates a sectional shaft stepped into a base 2 on one of the floors 3 of a building, the sections being united by a coupling hereinafter described, and said shaft carrying on its upper section a bevel or other gear 4, the hub of which is seated in a bearing 5 on another floor 6, said gear 4 being actuated by a pinion 7, rigid w th the end of a driving-shaft 8.

Rising from the gear 4 are rods 9 carrying a tubular guide 10, and either integral with or attached to said gear is a conical head 11, having passages for the strands 12 of the cordage, as shown in Figs. 2 and 12.

Rigid with the sectional shaft 1 between the two

floors

3 and 6 are

spiders

13 and 14, each spider being composed of multiple arms projecting from a common hub 13 14 keyed to said shaft.

On the base 2 is a fixed gear 1.5, and projecting from each arm of the lower spider 14 is a stud 16, upon which is sleeved an idler 17 in mesh with said gear 15.

Journaled in each vertically-aimed pair of arms of the spiders is a flier 18, and as each flier contains the same elements, like numerals will be employed to designate like parts on all of the fliers of the series employed. On their upper extremities the fliers are each provided with a tubular trunnion 19, journaled in a bearing in each arm of the spider 13, and on their lower ends with a trunnion 20 which projects from the lower cross-bar of each flier, and these trunnions are journaled in the free ends of the arms of the spider 14. Each trunnion 20 carries at its lower end a gear 2], in engagement with the idler 17, and as said idler is in mesh with the fixed gear 15, and the spiders are rigid with the rotary shaft 1, it will be seen that each of the fliers has a compound 1noven1enti. c. a revolving movement and an axially-rotating movement, said movements being necessary to the proper lay and twist of the strands 12, as will be obvious on inspection of Figs. 2 and 12 of the drawings. In the skeleton-frame of each of the fliers, about midway of the side-bars thereof, is detachably secured a shalt 22, and upon this shaft is loosely mounted a bobbin 23, loaded with a coil from which the strand 12 is conducted. Each bobbin carries a gear 24 on the exterior surface of one of its end-plates or flanges 24, and this gear engages a gear 25 on a shaft 26, journaled in a bracket 27 of the flierframe, said shaft carrying a brake-pulley 28, for a purpose hereinafter described.

To the top of a vertical standard 29 of the bracket 27 is pivoted a lever 30 having an offset end 30, to which is articulated a concave brake-shoe 3]. conforming to the surface of the brake-pulley 28. At its end opposite the point where the brake-shoe is attached the lever 30 is perforated at 30 and in the arm of said lever is mounted a stud 32 perforated at 32, and through the eye of this stud is passed a rod 33, upon which is mounted below the lever a wing-nut 34, said rod having at its upper end a hook 34 engaging an eye on the sliding part of spring-scales 35, illustrated in Figs. 2, 3 and 4. This stud has a straight surface 36 bearing against the lever 30 and is reduced at 36, where it passes through the lever, the reduced part being provided with a tln ead to receive a jam-nut 36 as shown in Fig. 16.

Hooked to the other part of the spring-scales is a rod 37 a threaded portion 37, of which passes through an open slot 38 in the free end of a lever 38, attached at 39 to a link or crank-arm 40, said link being pivoted at 41 to one of the side bars of the flier. At its end opposite the slot 38 the lever 38 is also bifurcated at 38 to receive the threaded end 42 of a rod or link 42, said rod being held in place by a nut 43. Swivel-nuts 44 and 45 are seated in perforations in the bifurcated ends of the lever 38, and are transversely perforated to re ceive the threaded

rods

42 and 37, said nuts being held against displacement by flange tubes or

Washers

46 and 47, as illustrated in Figs. 4 and 17 the lower en ds of the tubes bearing against said nuts when forced downward by nuts 37 applied to the threaded rods, as illustrated in said I ig.'17. in the end of the crank-arm 40 is a perforated bolt 48, having a nut 49 for securing it in place. Designated by 50 is a rod, the lower end of which is secured to said crank-arm by the eye-bolt 48 in any desired manner, and the upper end of which is articulated to an element of compensating-mechanisan hereinafter described.

Designated by 51 is a bifurcated weight, having bearings 52 and clamp-screws or pins 52 by which it is secured to a rock-shaft journaled in bearings 53 of the side-frames 5454 of the flier, said rock-shaft being designated by 55. Rigidly secured to the rock-shaft between the arms of the weight is a curved follower 56, the free end of said follower bearing against the coil carried by the bobbin, as shown in Figs. 2, 3, and 4. Secured to the rock-shaft 55, one on each side of .the weight 51, are collars 57, and surrounding the said rock shaft are coiled torsion-springs 58, one end of each of which'is connected to a bearing 53 of the flier-frame and the other end to said

collars

57, 57, said springs tending constantly to turn the shaft, and to hold the follower 56 against the coil on the bobbin as the strand is paid off therefrom. (See Fig. 18). Rigid with one end of each rock-shaft 55 is an arm 59, in a slot 59 of which is hooked a flattened extremity of the rod 42, and depending from each rock-shaft is the weight 51 just described, which acts as a counterbalance to prevent the displacement of the follower under the action of centrifugal force, due to the rapid rotation of the flier. In other words, as the flier rotates centrifugal force will tend to throw the weight 51 outward, and consequently to turn the rock-shaft 55 to which theweight is secured inward, and thus cause the follower 56 constantly to bear on the coil on the bobbin.

Having thus described the fliers, bobbins, and followers attention will now be given to what is termed the compensating mechanism for automatically regulating and controlling the passage of the strands from the bobbins, so that all of said strands will be under equal tension. This compensating-mechanism is designated in a general way by the numeral 60, and is carried by a frame or stand 61, bolted to the upper inclined portion of the side frame of each of the fliers, as illustrated in Figs. 2, 5, 6, and 11. .Tournale'd in bearings 62 in the side of the frame 61 is a screw-shaft 63, which engages a nut in a traveler 64, said traveler having a lateral stud 64 perforated to receive the upper end of the rod 50, above described, and being secured in place by a belt 64 the lower end of said rod being hooked into the perforated belt 48. To the screwshaft 63 above the upper bearing 62 are rigidly secured gears 65 and 66, the gear 66 having a depending hub 66 by which it is spaced apart from the gear 65. In mesh with the gear 66 is a gear 67, having rigid with its hub a ratchet-disk 68, shown as connected to said gear 67 by a key 67 said gear 67 and its ratchetdisk being loosely mounted on a stationary stud shaft 69 secured to and projecting from the upper part of the frame 61. Designated by 70 is a short, stationary stud shaft projecting vertically from frame 61, and upon which is sleeved an idler-pinion 71 in mesh with the gear 65 of screw 63, and also with a gear 72 loose upon the stationary shaft 69 and carrying a ratchet-disk 73,the united gear 72 and ratchet-disk 7 3 being located on said shaft 69 below the similar gear 67 and ratchet-disk 68, as illustrated in Fig. 11. Projecting from the frame 61, is a stationary shaft 74, and sleeved at their hubs upon said shaft are angle-

levers

75 and 76 located one above the other. To one arm of the angle-lever 75 is pivoted a pawl 77 held to position to engage the ratchet-disk 68 when the angle-lever is rocked by a spring 78, and to the like arm of the angle-lever 76 is pivoted a pawl 79 held in position to engage the ratchet-disk 7 3 by a spring 80, as shown by Fig. 14, the inward movement of said pawls being limited by suitable stops, for in stance, by the walls of the bifurcated ends of the levers in which the pawls are pivoted. A post 81 projects from the frame 61, and against said post the

inwardlyprojecting arms

75, 76 are held, each by a

spring

82, 82 as illustrated in Figs. 14 and 15. For a purpose hereinafter described the arm .75 is slightly shorter than the arm 76 (see Figs. 5 and 11). As will be observed the screw 63 is oflefthand pitch and, therefore, when the gear is actuated the traveler 64 will be forced downward, and when the screw is reversed by gear 66, said traveler will rise on the screw, thus through the connections described, in one instance causing the brake 31 and follower 56 to bear with greater pressure on the brake-pulley and coil on the bobbin, to retard the passage of the strand, and in the other instance, retracting said elements under the influence of the spring-scale 35 and connections described to permit of a more free passage of said strand from the bobbin.

Each arm of the spider 13 is channeled at 13 and secured to one wall of the channel are brackets 83 having bearings 84 in which is journaled a rock-shaft 85 carrying a bifurcated crank-arm 86 at one end, as shown in Figs. 8 and 9. At its opposite extremity the rock-shaft 85 is provided with a bifurcated crank-arm 87 engaging a laterally-projecting pin or rod 88.

Secured to the base of each arm of the spider 13 is a block 89, longitudinally bored at 89, 89 and having a slot 89 for the reception of the pin 88, which projects from the plunger hereinafter described. In the bore 89 is mounted a stop-plunger 90 having a rack 90, and in the bore 89 is located a shorter stop-plunger 91 carrying the pin 88 and having a rack 91. .lournaled in the block 89 is a pinion 92 in mesh with both of the

racks

90 and 91, so that the longer stop-plunger 90 will always be actuated in a direction opposite to that of the shorter stop-plunger 91, when the latter is operated by the rock shaft in a manner hereinafter described.

Loose on the pin 93 passing through the arms of the crank 86 is a sleeve 94, and threaded into a tubular boss 94 of said sleeve is the lower end of a rod 95, as illustrated in Figs. 8 and 9, the upper extremity of said rod being hooked into a perforation 96, where it is held by a nut 96 in the rear end of one of the arms of a double angle-lever 96. This angle-lever is pivoted on bolts 97, 97 to the inner sides of the arms of a bracket 98 secured to and projecting from a coupling 99 uniting the two sections of the shaft 1.

Threaded into a swiveled crossbar 100 uniting the two arms of the angle-lever 96 adjacent to their rear ends is a rod 101 having a hook 101 at its lower extremity, said hook being inserted in an eye 102 on the 104 of said spring scale is hooked a threaded rod 105,

in threaded, adjustable engagement with a nut 106 on I the arm of the spider, as shown in Fig. 5.

Journaled in the outer end of the double angle-lever 96 is a roller 107, over which the strand from the bobbin passes, as shown by dotted lines in said Fig. 5. A link 108 is connected at one end to one of the arms of the double angle-lever 96, and at its other extremity to a pointer 109 pivoted at 11.0 to an upward extension of the bracket 98, and carrying at its end opposite the pivot a pointer 109 working in a guide 111, and coop erating with an indicating point 112 on a standard 113, resting upon the top of the bracket 98, and connected by straps 114 to the section of the shaft 1 above the coupling 99, as illustrated in Fig. 6.

Adjacent its outer end each channeled arm of the spider 13 is bridged by the base 115 of a bracket 115,

said

bracket having arms

116, 116 between which a roller 117 is journaled, the strand passing over said roller, as shown in Figs, 2, 5, 6, and 7.

A guide-roller 118 is journaled in the arms 119 of a bracket 119, the hub of which is secured at 120 to the shaft 1, and the strand passes under said roller on its way to the head 11.

A stop 121 depending from a bracket 53 prevents, by contact with arm 59 rigid with shaft 55 the follower' 56 from inward movement beyond a certain point when the bobbin is removed.

As illustrated the strands are all supposed to be under equal tension, and both stop-

plungers

90 and 91 are in normal position, and are removed from the paths of travel of the arms 76 of the

levers

75 and 76.

In the operation of the improved machine, tilled bobbins are placed between the arms of each flierframe, and the shafts 22, upon which the bobbins rotate, are inserted through said bobbins, and are secured in position. Strands from the bobbins are then drawn through the tubular trnnnions 19, over the

roller

117, and 107, under the rollers 11.8 and through the passages or grooves in the head 1]., when the machine is set in motion and the strands are twisted together to form the Cordage, which as completed passes through the tubular guide 10, and from thence to any point desired, for instance, to a device for forming the rope into a coil, or upon a reel.

As stated in the general description, a follower 56 is secured to a rock-shaft journaled in. bearings 53 of the side bars of each flier-frame, and torsion-s 'nings 58 tend constantly to hold said follower against the coil, and to maintain it thereon as the diameter of said coil is reduced, and as also stated each bobbin is geared with a brake-wheel 28, upon which a brake-shoe 31 is arranged to bear, said brake-shoe being under the control of the compensating-mechanis1n, and the pivoted lever 30, by which the shoe is carried being connected to the spring-scale, or it may be other, tension-device, 35, the tendency of which is to rock the lever, and vary the pressure of the shoe upon the brake-wheel. This tension-device 35 is also connected to one of the arms of the pivoted lever 38, controlled by said compensating-mechanism, and the other arm of lever 38 is connected by a rod 42 with an arm 59 rigid with the rock-shaft 55 carrying the follower 56. As the strands 12 from the bobbins each pass over a roller 107 held under tension by the spring-scale 103, the lever 96 carrying said roller being connected with the compensating-mechanism aforesaid, it is obvious that if any strand should be too slack greater pressure must be applied to the brake-wheel, and if too tight less pressure must be applied to said wheel. Assuming the strand to be under insufficient tension this will be immediately indicated by the pointer 109, which will drop below the point 112, and the lever 96 will under the stress of the spring-scale 103 be rocked on its pivot to throw the roller 107 further outward. As this takes place the rear arm of said lever connected to the springscale aforesaid, and by the rod 95 to the rock-shaft 85, will actuate said rock-shaft, rocking it downward and through the bifurcated arm 87 and pin 88 sliding the stop-plunger 91 downward and the stop-plunger 90 upward, thus locating said stop-plunger 91 in the path traversed by the arm 75 of lever 75 revolving with the flier-frame around the shaft 1, and rotating with said frame as above explained.

When the arm 75 engages said stop-plunger 91, lever 75 will be rocked on its pivot 74, and the pawl 77 will engage a tooth of the ratchet-wheel 68, thereby rotating said ratchet-wheel and its connected pinion 67, and through the gear 66 in mesh with said pinion actuating the screw 63 and causing the follower 64 to rise on said screw. Inasmuch as this follower is connected by the rod 50 with the arm 40, pivoted at 41 to a part of the flier-frame, and carrying the pivoted lever 38, it will be seen that as said rod 50 rises the lever 38 will partake of the same movement, and as said lever is connected at one end by the rod 37, spring-scale 35, and rod'33 to the pivoted brake-lever 30, and at its opposite extremity by rod 42, and slotted'arm 59 to the rock-shaft 55, it will be seen that the brake 31 will be applied with greater pressure to the brake-wheel 25, and the curved follower 56 with greater pressure to the coil on the bobbin, thus retarding the passage of the strand therefrom, and causing said strand to leave the bobbin under the requisite tensional condition.

If at any time a strand should be paid off from a bobbin under too great tensional condition the roller 107 carried by pivoted lever 96 will be forced back and the pointer 109 connected by link 1.08 with said lever will rise above the indicating-point 112. This movement of said lever will raise the rod 101, and produce greater tensional resistance on the spring-scale 103, and will also lift the rod 95 and rock the.crank-arm 86 and rockshaft 85 in such direction that the stop-plunger 91 will be raised, and the pinion 92 will be rotated by the rack on said plunger 91 from right to left, thereby depressing the stop-plunger 90 to a point where it will engage the arm 76 of the lever 76. Now, as the flier rotates the arm 76 of pivoted lever 76 will engage said stop-plunger 90, the said lever will be rocked and its pawl 79 will turn the ratchet-disk 73 and its connected gear 72 in mesh with the idler 71, and the gear 65 on the screwshaft 63 will be turned in the same direction as the gear 72, thereby imparting motion to the screw 63 in a direction. opposite to that in which it is driven by the

gears

66, and 67, and thus lowering the follower 64 and rod 50, forcing down the lever 38, and the connections therefrom to the pivoted brake-lever 30, and rock-shaft 55, and relieving the pressure of the brake 31 on the brakewheel 28, and of the follower 56 upon the coil, thus enabling the strand more freely to leave the bobbin. When the strand is in normal condition the pointer 109 will be opposite the indicating-point 112, and when the pressure on said strand varies it can immediately be detected by the position of the pointer either above or below said indicating-point.

As will be understood the

springs

82, 82 normally hold the

arms

75, 76 of the pivoted pawl-carrying

levers

75 and 76 against the post 81, and after one of said lever-arms passes the stop-plunger then in lowered position it will immediately snap back against said post.

By adjusting the screw-

rods

33 and 37 the tension of the spring-scale 35 may be regulated as desired, so that the pressure applied by the brake 31 (through lever 30) and by the follower 56 (through lever 38, rod 42 and lever 59,) will produce the required pressure on the strand as it is drawn from the bobbin. To illustrate, when a filled bobbin is in position between the parts of the flier-frame the follower 56 should bear upon the coil with a pressure say of one-hundred and eighty pounds, and the indicator of the spring-scale 35 should indicate this number of pounds, and as the coil is reduced in diameter this pressure should progressively vary, until, finally, when or thereabouts, the coil is exhausted, and the follower is in contact with the drum of the bobbin the scale should indicate about one-sixth of the startingpressure 1'. e. thirty pounds. In other words, the pressure on the lower scale 35 is reduced proportionately to the leverage exerted by follower 56 upon the coil.

An equal tension on the strand 12 must be maintained at all times, and therefore, as the power necessary to draw the strand from the bobbin constantly increases as the diameter of the coil on the bobbin diminishes, it is obvious that the pressure applied by the brake 31 must also constantly diminish, or be reduced proportionately to the leverage on the bobbin.

Any suitable means may be substituted for the spring scale illustrated and described,-the invention not being limited in this respect. So too, the compensatingmechanism may be varied within wide limits, and various devices different from those shown may be employed for controlling the passage of the strands, so that an even lay thereof will be effected, and the cordage will be of standard twist throughout, without departure from the invention.

Changes may be made in the form, proportions, and various details of the machine, and many of the details thereof may be employed in arts different from that of cordage manufacture, and still be within the purview of my invention.

Having thus described my invention, what I claim is:

1. The combination, of the following instrumentalities revolving and rotating fliers; bobbins on said fliers; and means for controlling the speed or each strand as it leaves the bobbin; mechanism carried by the fliers for actuating said controlling means; and means operative on the rotation of the fliers for operating said mechanism.

The combination, of the following instrumentalities: revolving and rotating fliers; bobbins carrying the coiled strands, and one mounted for rotation on each flier; compensating-1nechanisni; means controlled by said compensating mechanism for maintaining the tension of the strand as it leaves the bobbin; and means carried by the flier-Support for operating said compensating-mechanism.

by each flier for controlling said means, whereby each of the strands will be maintained in equal tension as the lay is formed; and plungers on each flier-support for actuating said controlling-medianism.
