MACHINE FOR MAKING CORDAGE.

SPECIFICATION forming part Of Letters Patent N0. 248,446, dated October 18, 1881. Application filed April 4, 1881. (No model.)

To all 'whom it may concern:

Be it known that I, JOHN A. GEBR. ot'Colehester, New Loudon county, in the State of Connecticut, haveinvented new and useful Improvements in Machines for Making Uordage; and I do hereby1 declare that 'the following is a full and correct description of the same.

By means of an expansive score-pulley my machine becomes capable of making several different sizes of cord. rIhe` strands are laid up in a vertical hollow spindle, and I am thereby enabled to reelit off from the bottom ot' said spindle -without occupying more room than is required to receive the reel. All the separate spindles are driven by a single band,and therefore a. uniform drag on the'strand is obtained without liability to slip.

That others may fully understand my invention, I will particularly describeit, havingreference to the accompanying drawings, where- 1n- Figure l is a perspective view ot' my n1achine. Fig. 2 is a vertical central section of the same. Fig. 3 is a plan view of the same. Fig. 4 is a perspective view of the eXpansible pulleys. Fig. 5 is a vertical central section of the same.

The frame of my machine consists of two horizontal spiders, A, bolted to a bracket, B, which is attached rigidly to some solid support. A hollow spindle,O, passes through the centers of the two spiders and has its bearings therein. At the corresponding extremities of the arms of the spiders A there are bearings for the spindles D D D, and a leader-arm, E, projects from the spindle O horizontally below the lower spider to lead the completed cord and lay it on the reel F,which is mounted and is capable of rotation upon an independent bracket or support below the lower spider A. Each spindle D passes up through its bearing in the upper spider, and is provided at its top with a pulley, G. The upper end of each spindle D is also made with a hollow center, and said hollow penetrates to a point below the upper bearing, where it has a lateral orifice, a, in the side of the spindle.

Near the bottom of each spindle D there isa platform, H, provided with a number of vertical spool-pins, I--say fivethough the num-` ber may be greater or less, and there is also on the'side of each spindle a guide-eye, J. The spools ot' thread Kare placed on thespoolpins I, an equal number of spools upon each platform H. The thread from each spool is passed through the guide-eyeJ ot its spindle, and is then wound one or more times around the spindle, to secure a proper frictional tension, and is then passed in at the orice a and out through 4the hollow center. The several threads thus grouped constitute one strand of the final cord. 4

A score-pulley, L, is rigidly secured to the spindle O above its upper bearing, and at the extreme upper end ot' said spindle there is a head, M, with bearings for a transverse feedroller, N, which is driven by a bevel-gear, b, at the one extremity ofits shaft, and said gear I) is, in its turn, driven by a similar gear, b', mounted on a score-pulley,O,which is located immediately above the pulley L, and turns upon the spindle C as an axis.

Above the head M there is a center piece, P, supported on a pillar, Q, and from said center piece,l three leader-arms,extend outward and downward, terminating just above the hollow ends of the spindles D; and immediately below the center piece, P, there is a clamptension, It, to regulate and make the twist or lay uniform.

The above are the mechanical features ot the machine.

Theseveral strands from the hollow spindles D are led up the respective arms d and brought together in the centerpiece,P, and thence they passdown togetherthroughtheclampRintothe head M and several times around the feed-roller N, and thence down through the tubular spindle O, and outward over the end of theleader-aim E to the reel F. The whole is driven by a single belt, S, which is actuated by any convenient or proper motor. The belt S comes to the machinetinthedirectionofitsinovement,asshown by the arrows,) and passes first around the pulley L rather more than half-way, and it thence passes over the pulleys G in successive order, and returns to the pulley O, around which it passes rather more than half and leaves the machine toward the prime-mover pulley. By this arrangement all of the rotating parts receive motion from the same belt, and necessarily the several movements are, as nearly as pos- IOC sible, synchronous. The rotation of the pulley G and spindle D carrythe several spools around the axis ot' said spindle, so that between its extremity and the leader-arm d the several threads arc twisted around each other or laid up in a strand, and in that condition the strands pass down through the clamp R to the head M and feed-roll N, the horizontal rotation whereot' is in a direction opposite to the rotation of the spindles l), so that the several strands are twisted together between the feed-roll N and the clamp R.

The head M and the pulleys L and O all revolve in the same direction; but the pulley O heilig of less diameter than the pulley L, it revolves with a greater speed, and the motion of said pulley O with reference to the head M, with the feed-roller and its driving-gear b, is therefore differential, the rapidity of the rotation ot' said feed-roller being dependent upon and in proportion to the difference in rotative velocity of said pulleys L and O. The velocity ot' feed with reference to rapidity ot' rotation ofthe spindle C will determine the lay or hardness of the twist, and incidentally the size of the cord made upon the machine may be varied, because a small cord will require more turns or twists to a certain length of feed than will a larger cord. Therefore by varying the relative diameters ot' the pulleys L and the lay may be varied or the machine adapted to cords of various sizes. To facilitate the adjustment of these relations l have made thc pulleys L and O expansible, as shown in Figs. 4 and 5, so that the diameters of their pitchlines may be varied at will, and without the dismemberment ot' the machine. This result I accomplish by makingthe pulley in two parts, divided horizontally through the groove, and provide each part with teeth e, the faces whereot` are beveled backward in the plane of the groove-tace, but interlocking laterally with each other, so that while said parts are in engagement with eachother at all, there will still remain a groove for the belt, but the diameter of the pitch-line ot said groove will be expanded as said parts are brought together, causingr the groove-faces to intersect farther from the center, and vice versa. They may be held in adjustment by a set-screw, s, or by some other suitable means.

llhe reel F is provided with afriction-brake, T, or other means ot retarding its rotation, so as to cause the cord to be laid upon it with any desired degree of tightness.

Havingdescribed myinvention, what Iclaim as new is- 1. A series of revolving' spool-platforms, whereby the threads are twisted to form strands, combined with a revolving tubular spindle and feed-roller mounted thereon, with means for operating the same, and pulleys G L and belt S, whereby the thread-twisters and the strandtwister may be actuated by the same belt, substantially as set forth.

2. A series of revolving spindles of which each one carries a platform adapted to support a set ot' spools, and means for operating the same, so that the several threads to form a strand are taken from the spools on said stands and twisted together, and a series of leaderarms combined with a tubular spindle and means for operating the same, whereby the strands are laid, afeed mechanism, andan arm, E, attached to and revolving with said spindle, and a reel whereon said arm deposits the nished cord.

3. A series ot' revolving tubular spindles each provided with a platform adapted to carry a set of spools, a tubular center spindle, and devices, whereby the cord is fed and delivered, combined with an actuating belt and pulleys to drive the Vseveral parts, arranged to be all actuated directly but independently by said belt, substantially as set forth.

4. A series ot spool-stands and a twistingspindle, whereby the threads are twisted to form strands and the strands are twisted to form the cord, a feeding device, and a revolving arm, whereby the cord is delivered, combined with an independent Winding-reel and a tension-brake for said reel, whereby its rotation is retarded, as set forth.

5. Arevolving twisting-spindle, a feed-roller mounted transversely thereon, and a drivingpulley connected to said spindle, combined with a variable diterential pulley connected with and actuating said leed-roller, whereby the hardness ot' the lay may be varied or the machine caused to make cords of various sizes.

A tubular twisting-spindle, a series of rotating spool-spindles, a series ot' leader-arms, whereby the twisted thread-strands are conducted into the end of the tubular twistingspindle, a feeding device, a delivery-arm, and means whereby said moving parts are actuated, combined with a reel the axis whereofl is coincident with the axis of said twistingspindle.

7. The twisting-spindle U, transverse feedroller N, and gears b and b', combined with the pulleys L O, whereby the speed ofthe feed with relation to the speed of the twister may be made differential, as set forth.

8. A feeding and twisting mechanism consisting ot' the tubular spindle C and feed device mounted upon and revolving with said spindle to twist the cord, but capable ot' an independent l'eed movement combined, with expansible pulleys L O, as described, and suitable devices to connect said pulleys with the spindle and feed respectively, whereby the hardness oftwist and lay may be regulated, as set forth.
