IMPROVEMENT IN NETTIN'G-MACHINES.

Specification forming-part of Letters Patent No. 152,062, dated J une 16, 1874; application iiled December 10, 1873.

To all whom 'it may concern:

Be it known that I, BENJAMIN ARNOLD, of East Greenwich, in the county of Kent and State of Rhode Island, have invented certain 'Improvements in Machines for Making Net- 'each other by means of grooves in the front,

back, and bottom of the support that holds them combined with knot-forming mechanism,

`as hereinafter described; and, also, in a series of hooks corresponding in number with the flat stationary bobbins combined with the latter, and so moved and guided as to convey a loop of twine from a separate set of bobbins over each lia-t bobbin, and leave it on the under side, so that when the loops are dra-w11 up they shall have passed around the bobbins; also, in combining two bars, one having a row of pins in its edge corresponding in space with the flat bobbins, and the other having on its Vedge a row of longer pins with holes or eyes -m thelr ends corresponding in space with the pins in the first bar, to form loops of the twine from the large bobbins; also, iu two rolls geared together and placed near eac-h other, with a bar or loose roll placed on top so as to rest on bothof them, combined with certain mechanism, as hereinafter described, for operating them to feed the net or twine through the machine; also, in a roll with staples set in its surface, through which the twines from the large bobbins pass, in combination with guides so placed as to cause the twines to wind up on themselves, and draw up the loops and knots when the roll is turned; also, in a guide-platemade'with vertical slots, and placed between the bars with pins, and the flat bobbins to guide the twines from the large bobbins and draw olf slack from the flat bobbins; also, in a series of points to open the loops that are formed by the pins before mentioned, and drawn out by the hooks, as herein described; and, further, in certain devices to give the proper motions to the above-men- Y tioned parts.

ing the lines of the sections. Fig. 2 is a vertical cross-section in direction ofthe dotted line a a in Fig. 1, looking to the left hand. Fig. 3 is a vertical cross-section in direction of the dotted line b b in Fig. 1, looking to the right hand. Fig. 4 is a vertical cross-section, taken in direction of the line c c in Fig. l, looking to the left hand. Fig. 5 is an elevation of the right end of Fig. l. Fig. 6 shows a perspective view of the machine. Fig: 7 is an elevation of the upper part of the lefthand end of Fig. l, with the driving-pulley removed. Fig. 8 is a back view of a part of the trough, showing the devices for opening the loops on the hooks. Fig. 9 shows the arrangement of the knee-levers that hold and move the two pin-bars, O K. Fig. 10 shows how the guide-bar holds the twine, so that it shall bind on the tie-roll. Figs. ll'to 17 inclusive show the positions of the two pin-bars O K, the twine, and the hooks in making the knots7 A A are two end frames, connected together by beams C C 0 at the front, back, and bottom. B is the main shaft, turning in bearings in each end frame. On this shaft are secured the cam O near the left end, and the cani D with gear-wheel E at the right end, and a loose sleeve, J, extends on the shaft nearly the whole distance between the two cams. To this sleeve the arms m are fastened. The cam C moves in succession the three levers a b c, and the lever a operates the sleeve J by means of the connecting-bar d attached to an arm on the sleeve. The lever b turns the tieroll F by means of the segment-gear on its upper en d, and the gear-wheel c on the tie-roll. This lever is brought back against the cam by the weight i, or in some other suitable way.

The lever c operates the feed-rolls G H by means of the connecting-rod g, lever j, rod k, geanrack h, and gear-wheel l', which is fast on a sleeve, to the outer end of which the arm k is fastened, which drives the ratchetwheel I, fastened to the back feed-roll, by means of pawlson the outer end of the arm I, (see Fig. 1,) the sleeve, &c., in section. Gam D (see Figs. 3 and 9) moves, by the outer groove on its inner side, the lever Z, which pushes the pin-bar K back and forward by the connect ing-rod a, knee-lever o, bar p, and knee-levers t. By the inner groove on the same face, it

moves the lever S, which raises land lowers the guide-plate j' by means of the rod q, kneelever r, and bar m. (See Fig. 9.) The cam l), by the groove in iis outer side, (see Figs.

5 and 9,) moves the kver N, which raises and y lowers the pin-bar O by the connecting-rod c,

or to every row of knots made; and the cam h attached to this gear-wheel lj gives those motions that are required to be the reverse inV tying one row of knots to what they were in the row next previous. The groove on the inside of the ea-m Q (see Figs. 3 and 9) moves the lever R, which moves the eye-bar O endwise by means of the connecting-bar y, kneelever or rocker-shaft z z, and bar c'. The shape of one-half of each groove on both sides of this cam is the reverse of the other Vhalf of the same groove, for the purpose of tying the knots right and left, to make the meshes diagonal. rllhe groove in the outside of the cam Q., Fig. 5, moves the lever Swhich gives motion endwise to the pin-bar K by the rod y', knee-lever x', Fig. 3, and the connecting-bar 'Lc'. The arms m' on the sleeve J (see Fig. 4) are connected to the bar V by the rods 'u'. In

this bar V a row of curved hooks, t', are set,.

agreeing in number and location with the at bobbins s', for the purpose of drawing the loops over the bobbins. The bar V (see Fig. 4) is guided in curved ways U by the arm W, which has a friction-roll near its lower end ruiming in the groove M. These oblige the hooks to catch the loops, draw them over the bobbins s', and cast themoif below. X is a trough, supported at each end over the front of the roll Gr, to hold the extra bobbins to replenish the machine with, and also to support the devices for opening the loops as they pass over the bobbins s'. These devices consist of the knee-levers g', (see Figs. 7 and 8,) pivoted to the back of the trough, and connected by the strips 0' to the bar p', which is made with a row of V-shaped points agreeing in number with the hooks t'. The other ends of the knee-levers q' are pivoted to the bar Y, which is operated by means of the knee-lever fi', connecting-rod h', and lever z, which is moved by a pin, d', in the wheel B'. The points on the bar p' spread the sides of the loops apart, so as to enable them to pass down cach side of the bobbins s'. The large bobbins n' hold the twine of which the loops are made that are passed over the bobbins s'. The lever D (see Fig. 7) is pivoted at one end to the frame A,

and connected at the other end tothe arm k' by the rod 1"'. It is pushed down by the pin d' in the wheel B', when the tie-roll has taken up most of the slack of the knot, to cause the feed-rolls to draw the row of knots that are being made away from the eyes a little, so

that they may be `properly drawn up tight without being drawn into the eyes. The-guideplatej' is placed on knee-levers, or their equivalents, sothat it may be raised for the purpose of drawing off slack twine from the flat bobbins, to form a part of the knot; and it is furnished with slots to receive the twines from the'large bobbins, so as tov guide them without drawing on themwhen the plate is raised to get slack from the fiat bobbins. The plate is operated by the lever S, rod q, knee-lever r, and bar m, and the inner grooves on cam-plate D. (See Fig. 9.) The twine a' is threaded in, as shown in Fig. 4-that is, from the large bobbins u' back over the bar b'; then up to the guides on the front of the bar H', thence through the staples in the tie-roll F, and ,through the guides on the top of bar H', then through theV guid-e-platej' and the eyes in the bar O to the bottom of frontfeed-roll; then up between the rolls, over the bar c', on top and down between the rolls, and out under the back feed-roll. rlhe iiat bobbins s' are placed on a support, (see Fig. 4,) and held separate from each other by ridges, forming grooves in the front, bottom, and back of the support, in which the bobbins Vstand on their edges. The twine c' from these bobbins'goes up through the feed-rolls in the same manner as the twine from the large bobbins, or they may be tied to the twines a' in front of feedrollG The machine'is driven by means of a belt on the pulley B', which is fast on the main shaft. The knots are formed as follows The pin-bar K comes forward and the eye-bar O drops down, (see Fig. 11,) then the pin-bar moves sidewise andthe eye-bar rises a little, (see Fig. 12,) then the pin-bar draws back far enoughA for the pins to clear the eyes and moves sidewise and forward to its iirst position, and the eye-bar drops down. (See Fig. 13.) The pin-bar now comes forward over the eyes and a little sidewise, so that when the eyes rise a little they are back of the lower part of the twine around the pins, (sec Fig. 14;) then as the pin-bar moves back, the eyes rise inside tlieloop around the pins, (see Fig. 15,) and the hooks t' enter 'under that portion of the twine that extends from the eye to the pin farthest from it, and catch it, the eyes dropping down a little to draw the twine onto the hooks, which then draw back and carry the loops which are opened by the points in bar p' down over the iiat bobbins, casting them oil' at the bottom by passing under the ledge on which the bobbins stand. The tie-roll F now begins -to turn and draws the loopsup back of the bobbins s' .and around the twine c', as seen in Fig. 16, the pinbar meantime having 'drawn back and left the twines around the eyes. Then the eye-pins drop out of the knot and it is drawn up tight (see Fig. 17) by a further turn of the tie-roll.

The large bobbin-twines tie rows of knots alternately with the flat bobbins to the right of them, and with those on their left. This is accomplished by reversing the endwise motions of the 1two pilrbais lin the .alternate rows, the

othermotions remain-ingthe same. This makes the meshes diagonal to the sides of the netting.

` At this time the cam C has moved around, so

as to press on thelever c, Fig. 2, and turn the feedrolls G H by the connecting-bars and levers, as before described, so as to draw the row of'knot's just made back from the pins, the distance they are drawn back being the size of the mesh, and it is regulated by sliding the clamp g on the lever j toward its pivot, so as to lessen the amount of draw motion on the rack h to lessen the size of the mesh, and the clamp is slid toward the outer end of the lever to increase the motion of the feed-rack and make the meshes larger. The arrangement of the guides on the bar H', whereby the twine is allowed to draw freely through the staple in the tie-roll F, when that roll is turned in to its farthest point and the loop is being made, and the way that one part of the twine binds on another portion when the roll turns out, so as to both draw up the loop and knot, and at the same time draw oi the necessary amount of twine from the large bobbins for thenext mesh, are shown in Fig. 10.

In Fig. 3 is shown the manner of gearing the feed-rolls G H, so that the back one, which is driven by the rack h, shall turn the front one.

The rod u', Fig. 2, connects the lever a to the lever c through the lever j, so that when either one is operating it will draw the other back to the cam. At s, Fig. 4, a small rod or wire may be laid on the twine between the roll F and bar H to make friction on the twines, and another rod may be put on the twines between the roll F and the bar b to take up the slack l twine when the roll turns back to place.
