Meewemw i @time r JOHN e. GARRE 'r-sON, or O'I N-oi'NNATi, OHIO. I Lette/rs Patent No. 83,621, dated-Nmzcmber 3, 1868; wntedatcd Octobm' 22, 1868.,

IMPROVEMENT 'IN LOOMS.

The Schedule referred to in these Letters Patent and making' part of the same.

To all Iwhom it may concern:

the pendants of the harness, by means of a finger, With-Y out the intervention of treadles or their equivalents, the iinger itself acting on the pendants.

Also, in forming a guiding-groove in front of the reed, by inserting pins in the' hand-rail, to guide the shuttle unerringly through the web, it being carried or driven by the guides in the guiding-groove, and I propelled by an endless cord, in'the hand of the operator, the guides transferring the shuttlelfroin one to the other as they meet in the middle of the web.

Also, a take-up motion, self-acting, and acting onlyA as the woven fabric requires moving or. drawing domi. Also, a shuttle or bobbin-holder, so arranged as to be attached to the inner end of one of `the guides, there to be retained until the other guide meets it and detaches it, and attaches itto itself, and draws it to the other side of the loom as the guide returns.

And I do hereby declare` that the following is a full,

had to the accompanying drawings, making a part of this specification.` n

Figure l is a perspective view of the loom put tomoved` the better to show' the Working parts.

Figure 2 is a back View of the hatten, showing the around the pulleys, so as to produce the desired move` ment in the guides to which it is attached, also showing the nger b audits attachment.

Figure 3 is a front View of the pendant-casco c, and the pendants d, (to which the harness-shafts are to be attached,) the pulley e, and the pendant-cord f, suspended on the pulley e. (Parts of the same are seen at like letters in iig.' l.)

Figure 4 is a section of the right side of the loom, showing the parts designed forthe take-up motion, the rag-wheel g, the lever h, the dog t, the pawl 7c, and the `fly m; also, an end view of the breast-beam, removed from iig. l.

FigureA 5 is the shuttle or bobbin-holder, adaptedto be attached to the guides, and be by them driven or drawn through the web, and transferred from one to the other, whenever. the guides meet each other, and there retained until the next meeting of the guides.

Like letters designate corresponding parts of all the fi es.

g'lo enable others skilled in the art tg construct and f guide and shuttle together. gether, except the breast-bean1,which has been reuse my invention, l will more particularly describe the parts, referring by letters to the same.

The shedding of the web is accomplished bythe action ofthe iinger b, g. l, on the pendants d d, iig. 1, the pulley e, and the cord f, fig. 3. The pendants are confined in the case c 0, iig. 3, (which is fixed to an adjacent part of the loom-frame) and play up and down far enough to give motion to the harness-shafts, to which they are attached, to produce a su'icient shed in the web, and are suspended bythe cord f over the pulley e, so that either pendant descending, elevates `the other, and they are caused to descend by the iinger b coming in contact with them, acting on a shulder with which they are provided for that purpose, as the hatten goes back, as seen at fig. l. The finger b is caused to act alternately on the pendants by means of the elastic cords w and x, and the lever y, iig. l, or their mechanical equivalents. The shuttle coming in V contact with the lever y, draws the iinger to that side,

giving more tension tothe cord w, and when the shuttle is at the other side, the tension is removed from the -cord w, and the cord x, by its elasticity, draws the finger to that side, in a suitable position to act on the shoulder of the other pendant.

The shuttle is traversed through the shed by an y endless cord, a c a, figs. l and 2, and two dat pieces of Wood or metal, called guides, o o, fig. l, havingon their inner ends loosely-hinged. latches, t t, fig. l, so clear, and exact description thereof, reference being arranged that when the guides and shuttle come in contact, the latch of one will fall into a notch in the shuttle provided for that purpose, and connect the To these guides, at the outer end, is attached the endless cord, reflected over pulleys as seen at igs. l and 2, so that any motion of 4 the cord will make the guides simultaneously approach manner of passing the endless cord, c a a, over and orbatten-cap extending down a little more than onehalf of the width of the reed, leaving a channel between the pins and the reed for the shuttle and guides to play freely in, say from one-eighth to one-quarter of an inch in ividth, to snit the thickness of the guides. (The pins are seen at n n, fig. l.)

Each guide should be six or eight inches longer than one-half the length of the reed,and one-quarter of an inch Wider than one-half its Width, and provided with a -iiatfpointed loosely-hinged latch, hooked as represented iu the figure at t, iig.l ,for the purpose of falling into the notch fu, iig. 5, in the shuttle, and retaining it while being moved through the web.

Fig. 5. The shuttle or b Obbin-holder is provided with the notch u, adapted to receive and retain the latches of either guide, but is only capable of receiving one at a time, so that when the shuttle is pushed to the centre of the lay or hatten by one guide, the'other latch of its fellow, and lias itout of the notch, and causes its own latch to occupy the notch, and bears o the shuttle to the opposite side of the loom, and retains it until the next meeting of the guides, when it, in its turn, is made to relinquish its hold, and its fellow bears off the shuttle.

The guides are moved, as above indicated, by the operator grasping the cord a 'a a at or near the centre of the hand-rail, and moving the hand first to the right and then to the left, till the desired effect is produced.

Take-up motion: The taking up of the .web is accomplished by a pawl, k, the ily on, the lever h, and the dog i, (all seen in iig. 4,) acting on the lag-wheel 'of the cloth-beam g. The pawl k is pivoted in the sword of the hatten, and works back and forth with the' hatten, and as the batten goes back, the pawl, by a notch in its under side, engages with the lever h and draws it back, and the dog falls into the lower notches of the rag-wheel, and as the hatten comes forward, it presses on the lever h, drives the rag-wheel, and takes up the cloth. And so every motionof the hatten would move the rag-wheel one or more notches forward, were it not for the intervening action of the y fm, which is so fixed, that when the vibrations of the hatten are long enough for the pawl k, with its notch near its loose end, to engage with the Aiiy, on going back, the fly will raise the pawl so high that it cannot engage with the lever h, and no eect will be produced on the rag-Wheel until there has been sov much filling thrown in that the vibrations of the batten are so much shortened that the pawl cannot reach the ily to engage With it, but consequently will engage with the lever h, and continue the taking-up processv until the Woven fabric is so far moved or drawn down, that the vibrations of the hatten are longr enough to cause the pawl to engage with the fly, as before stated, making-a take-up acting with great regularity, and well adapted to hand-loom Weaving.

Operation.

By the hand-rail push the hatten back, and the shed is made. Then firmly grasp the cord a a a. near the middle of the hand-rail, and move tlie hand to the right until the guides meet and the shuttle is exchanged from one guide to the other. Then bring the hand back to the middle of the hand-rail, and the shuttle will have passed through the web. Beat up the iilling and repeat the process; a process well adapted to Weaving ragcarpets, as the shuttle-motion is altogether under the control of the hand of the operator, and may be so carefully conducted, that the tenderest rag1ling will scarcely ever break.

What I clamas my invention, and desire to secure by Letters Patent, is

1. The combination ofthe hatten, the finger b, the pendants d, the cord j, the pulley c, and the case c c, for the purpose of operating the harness, as above described.

2. The cords w and x, in combination with the lever y and finger b, for the purpose of operating the pendants, as abovel described.

3. The combination of the guide-pins 'n 'n.u, with the hand-rail or hatten-cap, and with the sliding guides o o, in the manner and for the purpose above set forth.

4. The endless cord a a a, arranged with the hatten and its guiding-pulleys, in combination with the shut tlc-Working or carrying guides o o, for the purpose above shown and described. i

5. The combination of the pawl k, the iiy m, the dog i, and the lever h, acting on the rag-wheel of the cloth-beam, and making a takeup motion, as above set forth and described.

In testimony of which invention, I hereunto set my hand, at Cincinnati, Ohio, this 7th May, 1867.
