.SPECIFICATION forming part of Letters Patent No. 325,368, dated September 1, 1885.

Application filed April 521, 1884.

To all whom it may concern.-

Be it known that I, ALFRED L. Turns, of the city and county of San Francisco, and State of California, have invented an Improvement in Machines for Spinning Hemp, &c.; and I hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to spinningmachines for fibrous material of different kinds, but specially adapted for spinning hemp, whether Manila, Sisal, Kentucky, Russia, or other forms of hemp.

My invention consists in the combination of devices which I shall hereinafter fully explain, and particularly point out in the claims.

The object of my invention is to effect economy in power and space and to provide a machine capable of doing increased work, as will be fully seen from the specified advantages of the machine in the course of the following description.

Referring to the accompanying drawings, Figure 1 is a perspective view of my invention. Fig. 2 is a vertical section of the same. Figs. 3 and 4 are details of construction.

A is a frame having an inclosed portion or base, 13, in which is confined suitable gearing which rotate the series of bobbins G and fliers D. This portion of the machine I do not intend to describe more particularly, as it constitutes but a well-known form of that class of machines used generally for spinning cotton, and known technically as a speeder. It is suffi cient to say that by means of suitable gearing or mechanism within base B, the bobbins are rotated rapidly to wind up the yarn. What I have said in this connection applies with equal force to the nippers E, through which the sliver passes in its course to the bobbins. These various devices, which are old in themselves, I adapt by the addition of the following novel features to my present particular purposenamely, the spinning of the hemp-sliver.

The frame A is carried upward, as shown, to form a support by means of a beam, at, for a frame, which consists of a suitable number of iron ribs, F, the sides of which have preferably a form in general outline of a rightangled triangle, as shown in Figs. 1, 2, so placed and supported by cross-piecesf on beam a, that the perpendicular of said ribs is on the (No model.)

side of and about in a vertical plane above the nippers and bobbins, while the hypotenuse is on the side from which the hempsliver is drawn.

Through the top of the frame A and the apices of the triangular ribs F passes the main driving-shaft G, upon which are the chaindriving pulleys g at suitable intervals throughout its length;

Through the bases of the ribs at each corner pass shafts H, which carry the chain-receiv ing pulleys h. The chainof this machine is not dissimilar in general construction to the chain of the ordinary horizontal spinningjenny used for spinning hemp, and it consists of a number of bars or rods, I, parallel and sepa rated by about equal distances. At each end these bars pass loosely through the overlapping and adjacent ends of connecting-links J, Fig. 8, while their centers are united and sup ported by link-bearings K, Fig. 4, through which the bars pass and are journaled therein, and which are pivoted to each other, as shown.

The chain, which is of course an endless one, is fitted over the frame formed by ribs F, and is driven by the chain-pulleys g 1., the end ones of which engage the chain by inserting their teeth between the bars, as in Fig. 2, while the intervening ones engage their teeth with the link-bearings K, Fig. l. The bars carry the usual jenny-pins, L, set rather more closely together than is usual in the horizontal jenny, and the ends of the bars are pro 'vided with the usual double crank-pins or dogs, M, which, by traveling on suitable guides or tracks, keep the bars turned to present their pins in the proper direction.

The points of novelty to be here noticed,in addition to the general position and course of travel of the chain,which, as I shall hereinafter show, constitute the main feature of myinvention, are the character of the bars I and the arrangement of tracks or guides upon which the crank-pins or dogs M travel, to adapt their movement to the novel course and position of the chain.

Usually the bars of the chain in the horizontal jenny are solid rods. I make my bars I of tubular iron, Fig. i, or other suitable metal,and thereby gain lightness and strength, which in a machine capable of such dimensions as the one under consideration are items of no small importance.

The tracks or guides for the crank-pins or dogs M throughout the greater portion of the travel of the chain are formed by the edges of the end ribs,F,and upon these edges the dogs travel and are guided; but when they arrive at the base or end of the perpendicular of the ribs, they leave it on a short curved track,-N, Fig. 3, by which they are directed upon a horizontal track, 0, across which they move,holding the bars in a position to direct their jenny-pins in a backward direction. WVhen they arrive at the end of the horizontal track 0, being momentarily relieved, the bars turn, and their jenny pins drop downward but then, again, the upper pin of the cranks or dogs, meeting the curved end or base of the hypotenuse of the ribs, forces the bars to turn their jenny-pins outwardly to come up behind and take the hemp-sliver, when the lower pins of the cranks or dogs again travel on the edges of the ribs.

The direction of travel of the endless chain, as shown by the arrows in Fig. 2, is up the sloping side and down the perpendicular.

In Fig. 2, P is one of the cans or receptacles in which the hemp-sliver is contained and from which it is drawn. P is the ordinary directing-mouth through which it passes to be taken by the jenny-pins.

I shall now explain the reasons for and advantages of thus placing the chain in a vertical instead of a horizontal position.

It has heretofore been customary in spinning hemp to use ajenny in which the chain moves in a horizontal plane, and which has the winding or spinning devices at one end.

' The sliver is carried by the chain over and along its top,while its under side returns free, thus utilizing but one-half of the chain. In my machine I utilize both sides of the chain. In the horizontal chain the lower returning side sags down and thus adds useless weight, making it necessary for more power to drive it. In my chain the descending perpendicular side counterbalances the ascending sloping side, and thus I need less p0wera fact which enables me to drive with an equivalent amount of power a much larger machine,capable of performing a much greater amount of work. Again, by putting the chain in a vertical position I economize space by carrying the dimensions in a direction where space is to be obtained, and is usually less availab1e-- namely, upward instead of spreading out the work horizontally over the most available space. But, lastly, by this position of the chain, I am enabled to usethe present superior improved spinners, known as speeders, by

adapting them for the spinning ofhemp-a use make a right-angle turn or bend in the course of travel of the hemp-sliver to reach the bobbin mechanism of the speeder, and this cannot be done with hemp, which is of such a nature that it must be fed straight. It will be seen 'in my device that the hemp is carried down directly to the speeder.

In Fig. 1 I show the means by which the ma chine is driven. Q is a pulley which receives thcdriving-belt R. Sisthepulley-shaft,which extends into the base Band drives the gearing or mechanism of the speeder. T is a beveled pinion on said shaft meshing with a beveled pinion, U, on a vertical shaft, V, which carries at its top a worm, WV, meshing with a worm-gear, X, on a shaft, 00. This shaft carries a pulley, Y,from which a belt, Z, extends to a pulley. Y, on the chain-driving shaft.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The main frame A and cross-beam a, in combination with the chain-supporting frame, consisting of the ribs F, supported on beam at and the cross-bars fisubstantially as described.

2. The main frame A, having the beam a, in combination with the chain-frame, consisting of the ribs F, having cross-bar f, resting on beam a, and the shafts G H in said ribs, having chain-pulleysg h,suitable pulleys and gearing for operating the shafts G and H, and the endless sliver-chain mounted on said frame and driven by theshaft G and pulleys 9, substantially as herein described.

In witness whereof I have hereunto set my hand.

ALFRED L. TU BBS.
