To all whom it may concern:-

Be it known that I, J OHN Nnsm'rn, of Lowell, in the county of Middles'ex and State of lllassachusetts, have invented a new and useful Machine for the Manufacture of Wire- Netting and Wire Fence by Power; and I do hereby declare that the sameis fully and clear- 1y described and represented in the following specification and accompanying drawings, letters, figures, and refercncesthereof.

'Of the sand drawings, Figure 1 denotes a .plan. Fig. 2 denotes a side elevation. Fig. '3 denotes anelcvation of i one of the parts of my netting-machine, which may be called the feeder. Fig. 4 is an elevationot' the other principal part of my machine, which I call the twister. Figs. 3 and 4-show the two principal parts of the saidinachine as discournected from each other, or an inside View? or elevation of each partwhcu they are connected to each other.

' The principal and main lectures of novelty .of my inventiou'consist in the principle of the revolving of the wires parallel to each other at the same time they are being twisted, and the other parts'aud movements of my'machine to produce theeil'ects hereinafter described.

To carry out my invention and design fully, and first to manufacture my wire-netting and wire-fence machines, it is the best plan, iu my opinion, to construct the various parts of said machines of such' materials as are hereinafter named. The frames should belof. cast-iron, .also the cams, the stands, andgearing of the same material, The levels andshippers throughout should be of wrought-iron. The

' iaws (r G may bemade of cast-iron, to'which must be' attached pieces; of steel where the same come in contact with the wires. The net-ting beam or cylinder vHI may be made of hard wood, with iron centers, and the ratchetgear on said cylinder may be of cast-iron.

The center part of the wire-reels maybe made of wood, with a sheet-iron rim on flange on each side.

It will be readily understood by any good practical workman, by inspecting the inclosed drawings and specification, and following out the details described hereinafter, how to make,

construct, and'use my wire-netting machines. It is necessary to have machines for making every different size of thejnetting or fence-,-

that is, for every difierent size of the meshes of the sameeand any width ofthe netting less than the whole scope of the machine can be made'by simply drawing in the number of v wires desired, as-willbeunderstoo'd hereinafter; and in proceeding to operate or use my netting e. machines it will be seen by examining the drawings that the same are composed of two parts connectedtogetherby two shafts, as seen at P and Q, Fig. 1, and one-of the said .parts I call the. twister, the frame of which The other part I g call-theflfeeder, the frame of which can be seenatBB,Fig.2.

" The border-wire to netting and top and betis shown at'A A, Fig. 2.

tornwire in fence is usually largerthan the wire to be twisted, although the wires can all be of the same size, if desired. The wire is placed-upon the reels 0 0, Fig. 1, and then one endofthe same is passed through a hole whiclrisdrilled in-the-ccnt-er of thefour cutside gears, E E andX X, Fig. 1. The said ivires are then passed to the twisting 'part of the machine, and through holes drilled in the centerslof, the two outside twisting-gears, J J

Fig. Then the said'wire is passed between the jaws G-G, Fig. 2, and then to the cylinder H, as seen at Figs. 1 and 2, and firmly secured to thesameby a clamp, g, and a catch, which can be seen at Figs. 1 and 2,-then the wires to be twisted, which are wound upon or around. the reels D D D 'D, Fig. 1. Said reels are then placed upon the stands I I I I, Figs.

1 and 2, on which they revolve as the wire isbeing'drawn off from them. One end of the wire on each of the four reels D D D D isthen passedthrough one end ,of the reelstands I I I I, Fig. 1, thence to and through.

the slots in the twisting-gears J J J J, Fig; 1., and then they are passed between the jaws G G, Fig. 2, and thence to the cylinder l'i, Figs. 1 and 2, andsecur'ed to the said cylinder by the same contrirauce ast-he border-wires, before described.- The said wires being all. ad-

justed, as-ab'ove mentioned, the power is applied to the'driving-pulley K, Fig. 1, which is conveyed to the shafts 1 and Q, Fig. 1, by means of the shaft L and gears L and M, as

seen at Fig; 1. The shippers S S S S, Figs. 1 and 2, being first raised by the cams R R and U U, Fig. 2, operating against or raising the.

levers T T, which are shown in Fig. 2, it being understood that the shippers'S S in the twisting part of my machine act in concert with and simultaneously with the shippers S S in the feeding part of my machine. By this moveme'ntth'ey'arebrought into the position as shown in Fig. 2 of'i'he drawings, and then stop moving, and as soon as the movement of the said shippers ceases the twisting-gears J J J J J, Fig.1, and the feeding-gears E E E EE and X X X X X, as seen at Fig. 1, make two revolutions, they revolving exactlywvith each other, so as to keep the wires parallel and from getting entangled with each other, two revolutions of the said gears being all the twisting that is necessary at each end of .the meshes in the netting. and fence for making good substantial work, although more or less twisting of the wire may be obtained, if desired, by altering the gearing in the following manner-via, by enlarging the gear N, Fig. 1, if more than two revolutions are required of the saidtwisting and feeding gears, and by reducing the gear N, Fig. 1, if less than two revolutions arc wantedin the said'i'eedi'ng and twisting gears at each end of the meshes in the netting;

The before-mentioned gears J J J J J and E E E E E and X XX X X,alter making two revolutions, as before stated, cease moving;

which is efi'ected by a part of the teeth 0!. the

gear N, Fig. 1, being cut ofi' from its periphery,

and as the said twisting and feeding gears stop revolving in such position-that the slots in the said gears are on aline with each other, so that the wires can be shipped from one set. of gears to the others by the shippers S S S S,

Figs. 1, 2, 3, and 4, and so that the wires can t be shipped back from one set of gearsto the others by the shippers V V V V, Figs. 1, 2, 3,

and 4, it bcingnnderstood that the said feed- I ing and twisting gears revolve and stop alternately-that is, they revolve when the shippers ceuse'moving, and that the shippers perform their duty while the said gears remain motionless, and as the said gears stop revolving the jaws G G in the twisting part of my machine are -inoved backward nearly to the twisting-gears 'J J J J J by the cant Y and arms and.connecting-pieces r, Fig.- 2, and the spring 6, Fig. 1, and by the peculiar eon structlon of the upper jaw, G, and connectingpieces 7', they (thcsaid jaws G G, Fig. 2) are brought together upon the wire and then moved forward,or toward the cylinder H, onehalf the'lengtli of the meshes of the netting, as will readily'be understood byinspection of the drawings, and when the wire is so drawn forward and the jaws G G stop, then the shippersS S S S, Figs. 1, 2, 3, and -t-that is, onev of the two sets of shippers on each side of the feeder-frame and one of thetwo sets of ship- ,1 pers, Figs..1 and 4, on each side of the-twisting-gears-sare first raised by the cams R and U, said shippers then remaining in this position .untilthe wire is sulticiently twisted. Then they are depressed ormoved downward .to their lowest position, as seen at V V V' V,

shipped from the position in which they were left by the shippersS' S SS to the other feeding and twisting gears, as will be read-' il y understood by inspection of the drawingsthat is, one setof shippers move the four inside wires one way and the other set of shippers will move the four-inside'wires'the other 'way at the required time to harmonize-with the other correct movements of themachine.

.lhe two' outside or border wires never move transversely, but move longitudinally, like the other wires, except that they pass through holes drilled in the center of the four outside feeding-gears and the two" outside twistinggears. lhe two outside small wires are wound twice around the border'wires at every other twistingop'eration, as will be seenby inspection of Fig. 1. 4

Thereel-stands I'III, Fig. 1, have'each a spring on the side-next the reel, the object be;

ing to produce friction and to prevent the wire be readily understood by practical workmen.

from-coming OffflI-hB reel'stoo easily.

The wire for netting, -fencing, should be well annealed. The'necessityof this will .The take-up motion to the cylinder H, Figs, ,1 and 2,1is composed of a ratchet-gear, h-,-Fig. .1, and cam 1', Fig. 1, and leverj, Fig. 1.

Atf, Fig. 2, is shown a shaft which supports a straight-edgc,-over which the wires travel as they pass through the machine.

(Z d, Fig. 2, are two movable planes that are moved or brought together by means of the cams Z and m, Fig. 1, and levers e and 'n, Fig.-

1, the object of the said planes being to guide the wires when they are shipped, and to hold the wires firmly while they are being twisted, so that the wires may not be sprung where they are not twisted, and at the end of each twisting operation they (the said planes dd) open or-move apart, but are together, as seen at d d, Fig. 1. On the top plane, d, there are five small vertical projections-one in the front of the center of each gear. These'projections are to prevent the wire from being twisted'too far'into the meshes. By inspecting the drawings it will be seen that the jaws G G are made in such shape that as they are moved backward by the cam Y and arms 0', the jaws are opened, and when they are moving forward they are brought in contact with the wire by shutting together,

by which operation the said wire is moved from one twisting operation to another, and so on. v 'It being understood that the take-up motion acts or operates at the right time, so as to keep the wire straight and smooth during the operation of the said machine, as hereinbefore set forth, and having thus described my invention, I will state my claims as follows:

1. Revolving the wires bythe means, suirstantially as described, for the purposes of keeping thern parallel to each other, so that get entangled with eachother process of making'the netting or they cannot during the fencing.

2. Vibrating the wires alternately from the left to the right,or the right to the left, be-

fore or after or at the sameItime of twistingthemflhe said wires) together, by means of the cams R and U, the shippers S S and V V, connected to the said cams by levers T T, asseen in the drawings, or substantially the same, for the purposes of making wire netting and fencing.

3. Thejaws or clampsG G, or the same'in substance, for the purpose of drawing the wire through the machine at the required times by meaii s of the cams and levers operating the same, essentially as laid down in the within specification and drawings.

4. The two planes d d, or their mechanical equivalents, with the cams and levers for operating the same, substantially as and for the purposes set forth.

5 The wire-reels and movable reel-stands,

with the friction-springs for the reels, and

same, and the said gears having slots cut in them, for the receivlng and sliding of the ends of the stands and wiresin the same, substantially as hereinbefore set forth and specified.v
