MACHINERY FOR MAKING coeos, ROPES, AND BANDS.

SPECIFICATION forming part of Letters Patent .No. 251,118, dated December 20, 1881. Application filed August 5, 1878. Patented in Belgium May 11, 1878, in England November 20, 1879, and in lranoe July 7, 1880.

To all whom it may concern:

Be it known that I, GEORGE FREDERICK JAMES, of the city of Manchester, England, have invented certain new and useful Improvements in Machinery for Making Cords, Ropes, and Bands, of which the following is a specifb cation.

The object of my invention is to provide a machine more desirable than-those heretofore in use for making ropes, cords, or hands, in which the yarns or threads placed in the machine in an untwisted state are tirst twisted and then laid to form strands, which are themselves laid to form ropes, cords, or hands.

The invention consists in a compact and efficient arrangement of machinery,,as specially hereinafter described, for twisting and laying the yarns to form strands and laying the strands to form ropes, cords, or bands at one operation, and for enabling the amount of twist, both in the strands and in the laying, to be varied by positive gearing in a simpler manner than heretofore,each yarn being regulated andmaintained at one uniform tension.

I It also consists in a novel knocking-off motion or mechanism for stopping the machine upon' the breakage of either of the yarns or strands.

' In the accompanying drawings, Figure l is a front elevation of a machine embodying my invention. Fig.2 is a sectional side elevation thereof. .Fig. 3 is a plan thereof. Fig. 4 is a horizontal section taken on the plane ofthe dotted line a: m, Fig.1. Fig. 5 is a horizontal section taken on the said dottedline was, looking upward. Fig. 6 is a horizontal section on the dotted line y y, Fig. 1; and Fig. 7 is a plan of the gearing for twisting the yarn and forming the strands.

Similar letters of reference designate corresponding parts in all the figures.

In carrying out my invention I take a srries ofbobbins or spools, A, (in this case nin'ein number,) and after warpingthe requisite number of yarns thereon, which will vary more or less, ac-

cording to the desired strength of strands, I

place them upon vertical spindles B, provided with fliers (J of ordinary or any suitable form. The spindlesB havea rotary motion imparted to them in the direction indicated by arrows upon thebobbins, Fig. 3, and thusthenecessary twist is put into each of the yarns. These spindles B are arranged in the following manner: They compose three sets of three each, and those of the several sets revolve in bearings in tables D, having a rotary motion around axes E, (hereinafter called the intermediate axes,) but in the opposite direction to the motion of the spindles, as shown by the arrows, Fig. 3. The three tables D have their hearings in a main table, F, which alsohas a rotary motion, and is driven by the shaft G. .This motion, however, is in the opposite direction to that of the small tables D, being' in the same direction as that of the spindles B.

It will thus be seen that the spindles B by their own rotary motion put twist into the yarns as they are drawn oft the bobbins A, by rotating around the intermediate axes, E, efl'ect the laying of three of the yarns into one strand, and by the rotation of the entire series around the common center shaft, G, effect thelaying of the three strands into one, forming a cord or band of nine yarns or three strands at one operation.

I will now proceed to describe, first, how motion is communicated to the center or main shaft, G; second, how motion is communicated to the intermediate axes, E, with the necessary change motion for obtaining a variation in the amount of hardness in the first laying operation; third, how motion is communicated to the spindles B, with the necessary change motion for varying the amount of twist put into the yarns upon the bobbins A; fourth, how the yarns are maintained at one uniform tension, fifth, the action of the self-stopping or knocking-off motion for throwing off the machine in case of' one of the yarns breaking.

Motion is communicated to the center shaft, G, from the fast and loose pulleys H H upon the horizontal shaft 1. J is a miter-wheel, at-

fixed upon the horizontal shaft I, and gearing with the miter-wheel K upon the vertical shaft I1, mounted in the bearing M, attached to the frame Not the machine. 0 is a pulley upon the vertical shaft L, which, by means of a strap or belt, P, drives the pulley Q, running loose upon the vertical shaft R, mounted in suitable bearings in the frame N. This pulley Q, is capable of being secured to the shaft B, so as to impart rotarymotion theretobyengaging with aclutch,

S, affixed thereto, and it may be disconnected from the shaft, so as to run free therefrom, by being disengaged from said clutch. A clutchfork, T, mounted upon the rod U, is provided for operating the pulley for the purpose of driving the shaft B.

V is a spur-pinion, fast upon the end of the shaft B, and through pinion W driving the spur-wheel W, secured upon the main shaft G. The low er end of themain shaft G is supported in the lower plate of the frame N, while the main table F, supported in the upper plate, I), of said frame acts as the bearing for the upper end of the shaft.

Upon the main shaft G, at or near the top, I mount an eyelet-frame, Z, fitted with eyelets 1, located immediately over the centers of the intermediate axes, E,for guiding the strands as they are formed to an eye, 2, located over the center of the main shaft G, and whereby they are gathered for the final laying operation.

A sleeve, 3, running loose upon the main shaft G and carrying a spuravheel, 4, gearing with spur-pinions on the ends of the intermediate axes, E,(see Fig. 5,) imparts motion to the latter. Theseintermediate axes have their bottom hearings in the lower table, 6, which is fast upon and revolves with the main shaft G,while the small tables D, resting in the upper revolving tables, F, serve to carry the upper end of the said axes.

The sleeve 3is, at its lower end, provided with a spur-pinion, 7, receiving motion from a train of wheels (see particularly Fig. 4) consisting of a spur-wheel, 8, supported upon a stud, 9, gearing with a removable pinion, 10, supported upon a stud, 11, and made fast upon and driven by an under pinion, 12, upon the same stud 11, the latter gearing with the pinion V upon the end of the vertical shaft R, driven as hereinabove described. The stud 9 is set in a slot, 13, concentric to the main shaft G and the stud 11 in a transverse slot, 14, so that the pinion can be readily removed and replaced by another and a proportionate alteration in the 'speed of the intermediate axes be effected.

The result of this combination is that while the intermediate axes are themselves carried or revolved round the main shaft G they are rotated at an accelerated rate of speed and in the opposite direction. The provision for removing the wheel 10 and replacing it by another and adjusting the wheel 8 to gear with the pinion replaced affords a ready and positive means for varying the speed of the intermediate axes, and consequently the degree of hardness of the first laying operation.

Motion is communicated to the several sets of spindles B by a train of wheel-work arranged in connettion with each intermediate axis, E, very similar to the last-described arrangement, a plan view of which is illustrated in Fig. 6. A sleeve, 14, runs loose upon each intermediate axis, E, carrying at its lower end a spurpinion, 15, gearing through the idle-wheel 16 with the wheel 18, mounted loosely on the stud l8, and having secured below it another gearwheel, 18 to which motion is imparted through the idle-wheel 18 from the wheel 17, mounted rigidly on the intermediate axis, E. Suitable concentric and radial slots are provided in the tables 6, so that the wheels 18 13 may be read: ily changed and the relative speed altered, by which the amount of twist put into the yarns can be adjusted to the greatest nieety. The sleeve 14' has at its upper end a spur-wheel, 19, gearing with the spur-pinions 20 upon the ends of the spindles B. (See Fig. 7.) By this combination. the spindles, while they are car-- ried or revolved round the intermediate axes,

E, are rotated in opposite directions, but at a much higher speed. The lower ends of the spindles B aresupported in the small tables 21, mounted upon the intermediate axes, E, while their upper ends are carried in the small tables D, as before described.

The yarns upon the bobbins are maintained at one uniform tension by means of the fliers O, notched bobbins, and weights 22. The weights22 rest upon pins passing through slots 23 in the spindles B from the drop-rods 24 (see Fig. 2) in'the hollow spindles B. The yarns are connected with the drop-rods so as to suspend the latter. Hence on abreakage of any yarn the drop-rod suspended thereby will be allowed to drop down in its spindle B.- The amount of tension isregulated by the weights 22, and can be varied at pleasure.

In case of one of the yarns breaking, it will be obvious that the weight 22'appertaining to such yarn will drop until the pin supporting it comes to the bottom of the slot 23. This is utilized to stop the machine in the following manner: The intermediate axes or spindles, E, are hollow and provided with drop-rods 25, (see Fig. 2.) secured to the flanged sleeves or tables 28, fitting over and sliding on the hubs of the tables 21 and suspending the drop-rods. When a yarn breaks the weight 22 appertaining to it drops upon the table 28 and, overcoming the spring 26, causes the drop-rod to protrude through the end of the intermediate spindle. As the protruding rod 25 is carried round it strikes against a finger, 29, upon a ring, 30, supported from the main frame N, (see Fig. 5,) and carries said ring round with it. From the ring 30 a stud, 31, projects.

The setting-on rod U is provided with a spring, 32, giving it a tendency to'fly upward and pull the pulley Q out of gear with the clutch S.

When the attendant sets on the machine he pushes down the setting-on rod U, so allowing the pulley Q and clutch S to intergear, and places a trigger-finger, 33, branching from the setting-on rod U, under the stud 31, so that it a yarn breaks and the drop-rod of any one of the intermediate axes, E, strikes either of the fingers 29the stud is carried oh" the triggerfinger 33, so allowing it to fly upward and draw the clutch S out of gear to stop the machine.

I provide a shaft, S, and friction-drums 34 and 35 for drawing forward the finished cord at a suitable rate. as mounted upon a shaft, 38, to which motion is imparted from the gear-wheel W, mounted on the main shaft G. The mechanism here shown for this purpose consists of a vertical shaft, 39, driven by means of gear-wheels 40 and 41, from the wheel W, (see Fig. 4,) and provided with a worm, 36, engag ng with a worm-wheel, 37, on the shaft 38. A belt, 42, passingover pulleys43 and 44, serves to transmit motion to the shaft S.

In conclusion Iwonld remark that although I have only described my improvements as applied to machinery for the manufacture of cotton banding, it should be understood that theand sets of spindles B might be arranged around the main shaft Gr, according to the number of yarns and strands required to form the cord, rope, or band.

It will also be obvious that the intermediate axes, E,- might themselves constitute the twistingspindles by carrying bobbins and fliers, and in this latter case a cord of three varns would be produced, and the small tables D and corresponding spindles, B, would be dispensed with. v
