MACHINE FOR MAKING CHAIN-LINKS FROM COlLED WIRE.
SPECIFICATION forming part of Letters Patent No. 283,556, dated August 21, 1883.
' Application filed November 8, 1882. (Nomodeld To all whom it may concern:
I Be it known that I, FRANK P. BARNEY, a citizen of the United States,- residing at Non ton, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Machines for Making Chain-Links from Coiled fire; and I do hereby declare the following to be a full, clear, and
. exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.
This invention relates to the manufacture of chain-links from wire coils; and in order that my improvements and their advantages may be better understood 1. will briefly describe the manner in which such links have hereto fore been made.
In the manufacture of links for watch and other chains from gold or gold-plated wire, inwhich the links, whether oval or cylindrical, are flattened, it has been the custom to take, for cylindrical links, a coil of wire about twelve inches long and slip the same upon ,a mandrel about fifteen inches long and of the same diameter as the interior diameter of the coil. This mandrel, with its coil of wire, is then pulled through a guide in a lathe-rest in the path of a burr or small saw set low enough to cut the coils in a line parallel to the axis of the mandrel or coil, and when all the coils are cut the links are removed, to be thereafter fiat-- tened. The flattening of the links is effected between two dies, one of which is the bed die or plate, while the other has a vertical reciprocatingmovement, and acts as a hammer, it being lifted and then allowed to fall upona few links spread upon the bed-plate. In throwing the links upon the bed-plate they often cross each other or lie one upon another, and the hammer striking them not only defaces the links, but-forces them out of shape and they are unfit for use. This practice results in serious losses, as the most expert fiat-toners cannot always spread the links so as tosepa rate all the links from one another, especially if he desires to perform a good days work. To do this work of flattenin g the links requires a skilled operative to avoid too great a loss in spoiled links, and, besides this, it is very slow and very tedious, and an expert workman cannot burr or out and stamp more than eight pounds of links in a day of ten hours labor. In making oval links, the coils, as they are wound, are all twisted, or what is technically termed corkscrewshaped. as described in an application for patent for process of and appliances for coiling wire, of even date'with this. These coils are cut up into lengths of about twelve inches, annealed, forced upon a gage about fifteen inches long to bring them back to their proper shape, and then sawed or burred and flattened or not, as above described. Serious losses occur here in the process of annealing in order to render the coil sufiiciently pliable to take out the twist by forcing it upon a or mandrel of the shape and diameter the coil should have, and the operation is a very slow and laborious one.
The object of this invention is to remedy the difliculties enumerated, avoid the losses incurred by the old methods of manufacturing chain-links, and to considerablyincrease the percentage of work done in a given time.
In carrying out my invention any suitable device may be employed for cutting the links from a continuous coil of from forty to fifty or more feet in length, or for cutting and simultaneously flattening such links, neither of which has ever been used, either singly or combined, and for the reason that continuous perfoot cylindrical or oval coils could not heretofore be produced by the means available for the purpose of ceiling. For instance, the continuous coil may be fed through a tubular guide over or under a rotating cutter, or such coil may be fed over a cylindrical guide over or under such cutter, and the links, when cut, maybe flattened by concussion, or the flattening may be effected by compression. The feeding devices to feed the coil along the path of the cutter may also be of any desired or approved construction or operation-as, for instance, two superposed grooved rolls may be employed to feed the coil, or cylindrical rolls may be employed for that purpose, After long experiments with all these various devices I have found that the best results are obtained by using a yielding feeding device, as experience has proved that feeding devices having hard surfaces deface or mar the wire coil passing through or fed along by them to such an extent as to render portions of it valueless for use as' chain-links. I have further found that a tubular guide through which the coil is fed to and within which the links are cut by the cutter has given better results than any other 7 guide experimented with; also, that, using a case when the compression is effected between through the spoilingof the wire by the feeding device or through the action of the flattening devices.
In the drawings, Figure 1 is a side elevation, Fig. 2 an end elevation, Fig. 3 a plan view, and Fig. 4 a longitudinal section, of the machine.
Like letters of reference are employed toindicate like parts wherever such may occur.
A is the main frame, constructed of any suitable material, and of appropriate forni to support the operating mechanism.
B 13 indicate a pair of feed -1'olls,' between which the wire coil is passed, and by which it is fed to the saw or burr, said rolls being covered with any suitable flexible materialsuch as cloth, felt, or other like material-though I prefer to use a rubber cover, I), as I have found that this material has no effect whatever to mar the polish of the wire, and is of great importance for T that reason. The rolls are mounted in standards a, projecting from the frame, and in rear of said standards is mounted a tubular guide, D, supported at or near its front end in a standard, a, and at the rear end by a rattler or spreader hopper, F, as plainly shown in Figs. 3 and 4..
The guide D consists of a metal tube, of the required interior diameter and shape to allow the cylindrical or oval coil to pass through, and has a flaring mouth, (I, to facilitate the introduction of the end of the coil in starting the operation.
Above the tube D, in standards a is mounted a burr, E, in such a position that its teeth will project through a slot, (2, formed for the purpose in the guide-tube, sufficiently far to cut the coil into links as it passes through the tube.
, The burr is rotated in a direction the reverse of that of the feed, as shown by the ar rows, the coil being thus made to act'as a resistance, the cut links being crowded or pushed toward the rear end of the tube, from 'which they fall into ahopper, F, that is or may be provided with cross-bars f, that serve to spread the links, said hopper acting as a rattler or spreader.
. The discharge end f of the hopper is of the same diameter transversely as that of one of the flattening or compressing wheels G, which is mounted immediately below the tube D and hopper F, as shown. The links as they fall from the discharge-mouth of the hopper pass between the periphery of the flattener or compressing-disk wheel G and the face of a larger or main compressing-disk wheel, H, between which the links are flattened, and from which they fall, ready for use, into a receiver, L. As the pressure exerted by the large disk-wheel is upon one side of its axis, this would tend to strain its shaft in its bearings, to avoid which I employ a bearing-disk wheel, J, that bears upon the opposite side of the face of the wheelH, as shown. To further solidify these parts and prevent end-thrust or backlash, I connect the shaft of the bearing-disk wheel J with that of the compressing-disk wheel G by means of a rod, L, having on one end a right and 011 the other a left hand screw-thread, said rod being connected with sleeves Z, secured to the shaft, in which sleeves the rod operates to move the shaft 9 of disk G away from or toward the wheel H. The rod L carries a hand-wheel, Z, for operating the same.
In the manufacture of chain -links from coiled wire, coils of various diameters and thickness of wire have to be cut, or cut and flattened, whether these are cylindrical or oval in cross-section, to suit the size of chainlink required.
To enable the machine to cut, or to cut and flatten, links of all sizes and thicknesses, the
parts must be so arranged as to accommodate themselves to the'altered circumstances. For this reason I make the feed-rolls, saw, and compressing-disk wheel G, adjustable in their bearings.
The adjustment of the feed-rolls is effected by the bearing-block b of the upper roll, made adjustable in the standards a of the frame. The saw or burr is likewise made adjustable vertically, as shown, and the compressing-disk wheel G is made adjustable longitudinally toward or from the disk-wheel I-I.
The shaft 1 of the disk-wheel G is mounted in bearings sliding in ways formed in the frame A, and is adjustable by means of set-screws S. I do not of course limit myself to the means described and shown for adjusting the feed-rolls, burr, and compressing disk or disks, as many other well-known and equally effective means may be employed for this purpose.
The various parts of the machine may be driven byany suitable arrangement of belting or gearin I have shown the feed-rolls driven from the burr-sha-ftand the latter shaft by cross-belt from the compressing disk -wheel shaft and the latter shaft is rotated from any suitable prime motor, the compressing- .disk wheel H and bearing-wheel J being ro-= tated by friction.
I prefer to rotate both the compressingdisk wheels, and this maybe readily effected by any mechanic versed in the art of gearing driving mechanism. For instance,.two counter-shafts, located transversely of the machine above the operating parts, may be belted together and driven from any suitable prime motor. One of these shafts may carry two pulleys to drive the compressing-disk wheels, and the "other shaft may carry two pulleys to drive the burr and feed rolls.
Toothed gearing may be employed to drive the various parts, or any other system or an rangeinent of belting, as may be found most convenient, as I do not wish to limit. myself to any particular arrangement of driving mechanism. \Vith such a machine an ordinary laborer can cut and flatten one hundred and pounds of coiled wire in an average days work.
In my application for patenthereinabove referred to I have described a cylindrical receiver for the reception and coiling of the wire as it is spun otf the peg. When the coil is cut, the receiver is removed and another receiver placed in position to receive the coiled wire. The end of the cut coiled wire is now passed between the feed-rolls and into the guide, and while the coil is cut into links, or cut into links and the links flattened, the coil-is again ready to be cut at the coiling-machine, and so on, so
that one man (who need not be a skilled artisan, as will be readily understood, as the machine's perform all the labor for which skill is required) is enabled to attend to both machines, and can, in a day of ten hours labor, coil one hundred and fifty pounds of wire and cut the coils into links andflatten the latter, while a skilled artisan,by the methods heretofore employed, will only work up, by hard work, between ten r nd fifteen pounds of wire.
From what has been said the advantages of my improved processes and machines will be readily understood. 4
Having now described-my invention, what I claim is- 1. In a machine for cutting continuous lengths of wire coil into links, the combination, with the cutting appliances anda guide to guide the coils thereto, of a pair of elastic feed-rolls, whereby the coil is fed to the guide .and cutting appliances, as described.
4. The combination,with the burr or saw E,
of the tubular slotted guide I), having a flar ing mouth, and the rubber-covered feed-rolls,
B, substantially as and for the purpose speci- 5. The combination, with the guide-tube D, of a pair of rubber-covered feed-rolls, one of which is adjustable vertically in its bearings relatively to said guide-tube, and a burr or saw, E, also adjustable vertically and relatively to said guide-tube, as and for the purpose specified.
6. In a machine for cutting continuous lengths of coiled wire into links and flattening such links as they are cut, the combination, with the guide and burr E, of appliances to compress and flatten the links as they fall from the guide, substantially as described.
7. The combination,witl1 the guide-tube, of the disk-wheels G H, operating substantially as described. i
8. The cOmbinatiOinu-ith the guide-tube and disk-wheels G H, of the hopper F, substantfally as and for the purpose specified.

10. The combinatioinwith the disk-wheel H, of i the adjustable wheel G- and bearing-wheel J, the shafts of which are adjustably connected by collars and rod L, substantially as and for the purposes specified. v
In testimony whereof I afiix my signature in presence of i we witnesses.
