S1913CIPI(L'A'JJIOIEQ' forming part of Letters Patent No. 373,818, dated November 29, 1887.

Application filed June 13, 1887. Serial No. 24l,103. (Ne model.)

To all whom it may concern.-

Be it known that I, HENRY S. DIX, of Plymouth, county of Plymouth, and State of Massachusetts, have invented an Improvement in Machines for Spinning Hemp,of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing likeparts.

This invention has for its object to improve the construction of that class of spinning-machines employed in the manufacture of hemp and similar fiber into ropes, cords, &c. As now practiced the slivers are taken from a can and conveyed by a comb-chain to and through 'a trumpet to a condenser, and thence to a flier,

to be twisted and wound upon a spool; but in practice this has been found objectionable, as

, the ends of individual fibers comprising the sliverseparate or project from the main bod-y of the sliver between the chain and thetrumpet or the condenser,the said projecting ends causing the rope or cord,when made, to look ragged or present a hairy appearance, and so, also, it frequently happens that the loose ends act to form bunches.

In accordance with this invention a conveyer is interposed between the usual combchain and the condenser, the said conveyer serving to grasp, hold, and convey the slivers uniformly to the condenser, thereby obviating the objections above noted.

The conveyer herein shown consists of two endless belts or carriers, which receive the sliver between them, and, as herein shown, the said conveyer having cooperating with it a pair of pressure-rolls,which act upon the sliver between the endless belts of the conveyer and the condenser, the sliver passing from the condenser to the flier and being twisted and wound on a spool therein in usual manner.

Figure 1,in side ele'vation,shows a sufficient portion of a spiuningmachine for spinning hemp to enable myinvention to be understood.

Fig. 2 is a top View of the machine shown in Fig. 1, the supportingstand for the pressure rolls and the pressure devices being omitted; Fig. 3, a cross-section of the fiier, taken on the dotted line 00 00, Fig. 1.

The hemp or other equivalent fiber to be made into a rope or cord is fed or delivered in usual manner into or upon the teeth or pins of a hackle-chain, a, passing around sprocketwheels 20, fixed to a shaft, to which is secured a toothed wheel, 21, driven by a pinion, 22, fixed to a shaft carrying a toothed wheel, 23, which is driven in any usual manner.

The flier O, to spin the sliver, the spool D, upon which is wound the rope or cord, and the condenser b are all as usual.

The conveyer, which forms the essential feature of this'invention, and which takes the sliver from the comb-chain (1, consists, essentially, of two endless bands, 2 8,0ne of which passes over three rolls, 4 5 6, while the other passes over three rolls, 7 8 9, therolls 4 and 7 being adjustable to keep the belts taut, while the rolls 5 6 and those 8 9 are so located with relation to each other in pairs as to keep a portion of one belt parallel to and so as to run in contact with a portion of the other belt, the sliver passing between the said parallel portions, and being held thereby in such manner and under such pressure as to prevent the free or loose ends of the fiber from standing out from the main body of the sliver.

At the rear of the conveyer,and cooperating with it, I have shown a pair of pressure-rolls, 1012, the latter being provided with an an nular groove, 16, at or near its center, and having its journals in a stand, 6, the roll 10 just above it having an annular projection to enter the groove 16, and having its journals in boxes 13, adapted to slide up and down in a groove of the portion 6 of the stand 6, the said boxes being acted upon by spiral springs 14, into which are entered screws 15.

The slivers, on leaving the rolls 10 12, enter the condenser b, of usual construction, and thence the sliver passes to the usual flier, 0, containing the capstans 60, (see Figs. 1 and 3,) by which it is twisted, the rope or cord so formed being wound on the spool D.

The two endless bands of the conveyer tend to keep the free ends of the individual fibers in contact with the sliver and present them to the rolls 10 12 in a straight line, so that when they reach the condenser they are formed into a compact uniform strand.

The pressurerolls 10 12 may be placed between the condenser and flier, and operating in the same manner to present the slivers to the flier at a uniform speed; or in the machine shown, containing the capstans within the flier, the pressurerolls may be omitted, and

ICO

A 3, and means, substantially as described, for supporting said bands and the cooperating presser-rolls 1O 12, substantially as and for the purpose set forth.

3. The comb-chain a, the condenser b, and flier 0, containing eapstans, combined with the sliver-conveyor, consisting of two endless bands, as described, interposed between the chain and the condenser, and means, substantially as described, for supporting said bands, substantially as described.

In testimony whercofI have signed my name to this specification in the presence of two subscribing witnesses.

HENRY S. DIX.
