CORDAG'E-IMACHINIE.

SPECIFICATION forming part of Letters Patent No. 633,957, dated September 26, 1899.

Application filed Jamm '7, 1899. seen at. 701,511. KNo model.)

To all whom it may concern:

Be it known that I, FRANZ J. F. GRAF, of

Passaic, in the county of Passaic and State of New Jersey, have invented a new and Improved Cordage-Machine, of which the follow-H ing is a full, clear, and exact description.

The object of the invention isto providea new andimproved cordage-machineformanufacturing ropes, cords, cables, and likearticles in a very simple and economical manner without requiring long rope walks and skilled mechanics, the machine being capable of turning out a large quantity of rope of a high similar characters of reference indicate cor- I responding parts in all the views.

Figure 1 is a side elevation of the improvement with parts in section. Fig. 2 is a sectional plan view of the same on the line 2 2 of Fig. 1. Fig. 3 is an end view of one of the. drawing devices and adjacent parts, and Fig. 4 is a plan View of the twisting-thimble.

The improved cordage-machine is mounted on a suitably-constructed frame A, supporting a post B, on which is mounted to turn the frame 0, preferably in the shape of a disk,- and driven from the main driving-shaft D by gear-wheels D a'ndqO', secured on the shaft Bend the frame 0, respectively. The main driving-shaft D carries fast and loose pulleys E, connected'by a belt with other machinery for imparting a rotary motion to the shaft D' and by the gear-wheels D and G to the frame 0 to rotate the latter horizontally on the post B. I I

In the frame 0 are arranged a number of radial slots C in each of which is held arod G on which is mounted to turn loosely a gear-Wheel F in mesh with a gear-wheel F, fastened to the post B by a set-screw or other suitable means, so that when the frame 0 is rotated the several gear-wheels F roll 0d on the fixed gear-wheel F. The rods 0 carrying the gear-wheels F, are made adjustable to permit of using different-sized gear-Wheels extending flange of the frameO.

F on the fixed gear-wheel F, The hub F of each gear-wheel F extends in an upward direction to form a bearing for the bobbin G,

between'which passes the strand H, unwinding from the corresponding bobbin G for the particular'flier I. The lowerdrawing-roller J carries on its shaft a worm-wheel J in mesh with a worm J secured on a shaft J journ aled in suitable bearings carried by the flier I, and on this shaft 3 is secured abevel gear-wheel J in mesh with a fixed bevel gearwheel C rigidly attached to an upwardly- It is evident that when the gear-Wheel F is rotated on the turning of the frame C, as previously explained, a rotary motion is given to the flier I, so that the drawing device 1 moves around the bobbin, and at the same time the bevel gear-wheel J 6 rolls off on the bevel gearwheel G so that a-tnrnin g motion is given to the shaft J and the worm J which latter rotates the Worm-wheel J and the'lower drawing-roller J Now as the strand H passes between the two drawing-rollers it is evident that the strandis unwound from its bobbin, the strand being then passed several times around the arm of the 'flie'r carrying the draw- .ing device or through apertures in the same to finally-pass from an opening I in the flier over the beveled collar (3 to and upon a fixed a disk K, secured to the upper end of the post B, the peripheral surface of said disk being 1 beveled, as is plainly indicat-ed'in Fig. 1.

Now as the flier revolves and is carried around bythe frame 0 it is evident that a twisting of the strands takes place between the flier and the fixed disk K, the twisted strand then passing from the disk K to the twisting de-, vice Lin the form of a thimble, the upper portionL of which is mounted to turn in a suitable bearing carried by a bracket A of the main frame A. Y I The lower portion L of the. thimble his bell-shaped and is provided with a number of apertures L corresponding in number to the number of bobbins carried by the frame O. For instance, as shown in the drawings,

four apertures L are formed in the thimble to correspond with the four bobbins supported on the frame 0. The apertures L stand at angles to each other and terminate in a common opening in the upper part L of the thimble, in which the twisting takes place as the thimble is carried around in its bearings by the action of the strands H moving with the fliers I. The twisted strands then pass between pairs of rollers N N and O and O and through an eye P to wind up 011 a reel Q the roll of rope, cord, or cable resting on two rollers R and R. The rollers N and O are made heavy and are mounted loosely in bearings A and A carried by the bracket A, while the lower rollers N and O are journaled in fixed bearings and are driven from the main shaft D by the gearing presently to be described.

On the shaft for the lower roller 0 is secured a sprocket-wheel 0 connected by a sprocket-chain O with a sprocket-wheel O, secu red on a transversely-extending' shaft S, journaled on the bracket A, the said shaft carrying a wormwheel S in mesh with a worm S secured on a shaft S connected by gear-wheels S and S with the main drivingshaft D, so that when the latter is rotated a rotary motion is transmitted by the gearwheels S S to the shaft S and the latter bythe worm S and worm-wheel S rotates the shaft S and the sprocket-wheel 0 which by the sprocket-chain O and the sprocket-wheel O rotates the roller O.- On the shaft of this roller 0 is further secured a sprocket-wheel N connected by a sprocket-chain N with a sprocket-wheel N on the lower roller N, the connect-ion being such that the roller N is r0- tated somewhat more slowly than the roller 0 to cause a stretching of the cord, rope, or cable between the pairs of rollers N N and O O. The rollerR is also rotated by sprocket wheels and chain from the lower roller 0, as indicated in Fig. 1, to givert-hc desired tension to the article between the rollers O O and the eye P to prevent curling up of the finished article previous to its being wound in a roll on the reel Q.

The operation is as follows: Then the several parts are in position, as indicated in the drawings, and the filled bobbins G are mounted to turn on the hubs F between the gearwheels 0 and the horizontal members of the fliers I and the several strands H are passed through the drawing devices and the fliers up over the fixed disk K and passed through the twisting device L to form a twisted cord,

rope, or cable, then the rotation of the frame 0 causes a drawing of the several strands by the drawing devices J to unwind the strands from the bobbins, as before explained. The

several strands are each independently twisted between the fliers and the fixed disk K,

and then the several strands are twisted toget-her in the thimble, and the twisted article is passed between the rollers N N to and between the rollers O and O to hold the twisted article firmly stretched, especially as the rollers O O rotate at a higher rate of speed than the rollers N N. The finished article then passes through the eye P to wind up on the roll Q, driven by the roller R.

It is understood that by the arrangement described any desired number of strands can be independently twisted and then twisted together to form a rope, cord, or cable of as many strands as there are bobbins carried by the frame C.

It will further be seen that the entire ma chine takes up a comparatively small space, and it can be run at a high rate of speed, so that it takes but a short time to finish the article and without the help of a skilled mechanic.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1.
