CHARLES H. REINISOH, OF NEW YORK, N. Y.

MACHINE FOR MAKING AND TWISTING CHAIN-LINKS.

SPECIFICATION forming part of Letters Patent No. 310,317, dated January 6, 1885.

' Application filed April 18, 1884. (No model.) i

To aZZ whom it may concern:

Be it known that I, CHARLES H. RErNIsoH, of the city, county, and State of New York, have invented a new and Improved Machine for Cutting, Bending, and Twisting Links for Chains, of which the following is a full, clear, and exact description.

My invention relates to a machine for making quartern chain-links, which machine comprises a revolving mandrel, over which the links are shaped, stationary and movable cuttingedges for cutting the links, and means for grasping and holding, and at the same time twisting, the links.

The invention consists of the means for revolving the mandrel intermittently, of the means employed for cutting and grasping the links while the twist is being formed, of the means employed for twisting the links, of the employment of a holding-bar to act in connection with the main cutting-lever, whereby the holding-bar will automatically adjust itself to anyirregularityin the rod or wire from which the links are being formed, of the means for operating the main cutting-lever and twister; also, of the general construction, combination, and arrangement of the parts of the machine, all as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of my invention. Fig. 2 is a broken side elevation of the same. Fig. 3 is a sectional plan view, taken on the line w x of Fig. 2. Fig. 4 is a sectional elevation, taken on the line 3/ 9/ of Fig. 2. Fig. 5 is a perspective view showing the stationary cutter and guide for the rodor wire from which the links are cut. Fig. 6 is a side elevation of the mandrel removed from the machine. Fig. 7 is a front elevation of the mandrel, showing the rod or wire from which the links are cut wound around it, and held by the clamp-wheel; and Figs. 8 and 9 show, re

spectively, side and end views of the twister removed from the machine.

A represents the main frame of the machine, constructed of cast iron, preferably, and with the table A, of such appropriate size and form as to properly receive and support the operating mechanism.

B is the main shaft, on which are fixed the pinions a a, and the two pulleys bone fast and one loose. The pinion a meshes with the large gear-wheel C, which has thelarge cam c, the short segmental rack d, and outer cam, 0, formed upon its inner surface for operating, respectively, the cutting-lever D, the toothed segmental bell-crank E, for turning the twister F, and the lever G, for raising andlowering the twister F, all in the manner and for the purposeshereinafter described, The pinion a meshes with the intermediate gear, H, and this gear I-I meshes with the gear-wheel I, placed loosely upon the short heavy shaft I, journaled in the heavy boxes I I.

Keyed fast to the shaft I, between the gearwheel I and the journal-box I, is the disk J. This disk J is provided with the pivoted dog f, which is pressed toward the gear-wheel I at one end by the springf, for causing the lug f of the dog to engage with the lugf formed upon the gear-wheel I, for locking the wheel I and disk J together.

Upon the journal-box I is formed or secured the toe 9, against which the projection f* of the dog f is adapted to strike at the proper time for disengaging the projection f of the dog f from the lug f on the gear-wheel I, thus permitting the wheel I to make a complete revolution independently of the shaft I and disk J before looking again with the disk J. In this manner, while the wheel I revolves continuously, an intermittent rotary motion is imparted to the disk J and shaft I, and also to the mandrel K, which is attached to the inner end of the shaft I by the square shank 7i? ofthe mandrel entering a corresponding socket made in the shaft, as shown clearly in Fig. 6. The rod or wire L, from which the links are cut, is fed to the stationary guide and cutter M of the machine over the said mandrel K, and the mandrel is made elliptical in form in crosssection, as shown in Fig. 7, for shaping the links. The rod or wire L, as it coils around the mandrel K, is made to conform to the shape of the mandrel by the roller h, under which the wire or rod passes, which roller h is journaled upon the pivoted arm h, which is pressed downward by the strong spring h-, the pressure of which may be regulated by the thumbscrew h, as will be clearly understood from Fig. 2.

m is the cutting-edge of the stationary guide and cutter M. The guide and cutter l\I is held in horizontal position and so as to stand at an acute angle with the mandrel K by the keepers M M, bolted to the top plate, A, of the frame of the machine, and these keepers may be made adjustable forwarying the angles of the guide and cutter, and the guide and cutter M is made trough-shaped and diagonal'at its cutting end m, and is so placed in the machine that the diagonal end an stands partially under the mandrel K, so that the edges m m serve to force the coils of the wire or rod L off from the mandrel K, and also to properly spread the coils so that the knife Z, secured to the short arm (Z of the cutting-lever D, may enter between the coils. so as to act against the cutting-edge m for cutting the links N one by one from the wire or red L, as will be understood from Figs. 3 and 5. The cutting-lever D is pivoted upon the stud j, and its main long arm (Z is adapted to be forced outward,

- ter twist or turn to the link.

causing the knife Z to approach the cutting edge on by the above-mentioned cam 0, formed upon the large gear-wheel O, and is adapted to be drawn inward by the spring 0, which acts through the transversely-arranged bar P, to be hereinafter described. After each link N is cut from the rod or wire L by the outward movement of the long arm d of the cutting-lever D, the ends of the link are grasped between the end a of the swinging holding-bar Q, and the face of the knife Z, which will hold the link firmly in vertical position, as shown in Fig. 2, until the twister F descends upon the folded end of the link, and is turned by means described below, for giving a one-quar- After the twist has been formed in the link, the machine be ing in continuous operation, the cam c on large wheel 0 will have passed the end of the I long arm (Z of the cutting-lever D, leaving it free to the action of the spring 0, which will act to draw the transverse bar 1?, the end Z1 of the holding-bar Q, together with the arm (Z of the cutting-lever D, from the position shown in Fig. 3 to that shown in Fig. 1,wl1ich movement will release the link N and permit it to drop down through the machine completed that is, formed and twisted. The holding-bar Q is divided at its rear end to form the arms 7.: k, and is placed upon the hub Z, which fits loosely in a socket made in the top plate, A, so as to be adapted to turn therein, and the hub Z is transversely screw-tapped to receive the screw-bolt Z. The point end of this bolt Z is reduced in size, and the reduced portion is passed through the lug Z formed upon the under side of the bar Q, and riveted, as shown in dotted lines in Figs. 1 and 3 and in full lines in Fig. 2, so that by turning the screw-bolt Z to the right or left, the bar Q will be forced forward or backward, being guided in its movementby the arms kk,wliich pass either side of the hub Z. \Vhen the proper longitudinal adjustment of the bar Q is obtained by turning-screw Z, the bar Q will be made fast to the stud Z by turning down the nut Z, placed upon the upper reduced and screw-threaded portion Z of the hub Z, which will lock the bar Q and the hub Z securely together. The holding-bar Q is yoked to the cutting-lever D by the above-mentioned transversely-arranged plate 1?, which is connected with the holding bar Q by the stud 0, formed upon the bar P entering a hole, 0, made in the holding -bar Q, and bar Q is yoked with the cutting-lever D by the flange 1) and screw p passed through the flange 2), so that its inner end rests against the outer edge of the cutting-lever D, as clearly shown in the drawings. The opposite end of the bar P is formed with the hook p for connection with the spring 0, the office of which spring, as above described, is to return the bar P. and with it the holding-bar Qand cut ting-lever D, to their original position after the cam 0 passes the end of the cutting-lever D. The end a of the holding-bar Q is made slightly diagonal, and this bar being connected to the cutting-lever D by bar P, it follows that when the lever D is forced outward by the cam c the front end, a, of the bar Q will be drawn forward (the bar turning the hub Z) to stand in front of and parallel with the knife Z of the cutting-bar D. By adjusting the screw Z the space between the end a of bar Q and the knife Z may be increased or diminished as required, according to the size of the rod or wire L from which the links are to be cut, and, owing to the direct longitudinal movement of the bar Q, caused by turning the screw Z, the proper parallelism between the end a and the knife Z will always be maintained at the time of cutting the link. The end a of the bar Q being held in front of the knifeZ at the time of cutting the link, the instant the link is cut off from the coil by the knife Z acting against the cutting-edge m of the stationary guide and cutting-bar M, the link will be firmly grasped between the end n and the knife Z and held as in a vise until the operation of twisting the link (yet to be particularly described) is performed, the holding of the parts in this grasping position being effected by the concentric surface 0 of the cam 0. By the outward movement of the cutting-lever D, effected by the abrupt edge e of the cam c, the outer edge of the lever D becomes an inclined horizontal plane, along which the point end of the regulating-screw p slides until it finds its own seat,which will be at the point where the link N becomes firmly held, be it large or small in diameter, so that the gripping devices for the links in this manner become automatically adjustable to any irregularity in the thickness of the wire or red L. The twister F is made square with the claw q at its lower end for receiving the link, and it is form-ed with the flange g at its upper end for resting upon the fingers 1' 7 of the lever G, as shown lIO clearly in Figs. 1 and 2. The square portion of the twister is placed loosely in a square passage made through the collar Rheld loosely in the ring S, formed at the outer end of the overhanging'bracket T, which holds the said collar It and twister F above the stationary cutting-edge an. The collar 1% is formed or provided with the flange 8 to prevent it from dropping through the ring S, and also with the arm U, which is connected by the connectingrod or pitman V to the segmental bell-crank E, above mentioned, which crank is pivoted upon the stud if, so that the teeth 0 thereof will be engaged by the rack (7, formed upon the large wheel 0 for causing the bell-cran k lever E to turn the collar R and twister F at the proper time to twist the link N. The movement of the segmental beltcrank R will be against the tension of the spring \V, which will act to return the bell-crank E, collar R, and twister F to their normal positions after the rack d passes the segmental teeth 6 of the bell-crank E, as will be understood from Figs. 1 and 2, The lever G is fulcruined upon the same stud 2- that the bell-crank E is pivoted upon, and the end 0 of the lever is adapted to be depressed by the above-mentioned cam 0 formed at the edge of the wheel 0 for raising and lowering at the proper time the twister F, so that the claw 1 thereof will engage with the folded end of thelinkN immediately after it is cut off from the rod or wire L, and while the link is held by the knife 2' and holdingbar Q, and while the twister is being turned for forming the twist or turn in the link.

The operation of the machine is as follows: Power being applied to the fast driving-pulley b to cause the main shaft B to be slowly revolved in the direction of arrow No. 1, the pinion a, meshing into the intermediate gear, H, and this gear, with gear-wheel I, will cause thelatter to revolve in the same direction with the shaft B, while the pinion a, meshing directly with large gear-wheel C, will cause this gear to revolve in the opposite direction-in the direction of arrow No. 2-a nd this gear 0 is of such size relative to the size of the gearwheels II I a that it makes but one revolution while the gear-wheel I makes two complete revolutions. The rod or wire L to be made into links is first given a few turns on a handmachine and is then slipped over the mandrel K under the p ressure-roller h, which is brought down firmly upon the first coil of the rod or wire by turning down the thumb-screw 2r. The slow motion given to the loose cogwheel I will bring the lug f thereof in contact with the projection f ofthe dogf, which will cause the disk J and mandrel K to perform one revolution, winding one link upon the mandrel and one link off into the guide M between the cutters. The dogf, by the action of the toe 9 upon projection f, then releases the lug f thus permitting the loose cog-wheel I to make another revolution while the disk J and man drel K remain at rest. The instant the lugf passes the dog f the abrupt surface 0 of the large cam 0, formed upon the large gear-wheel G, will force outward the main arm (1 of the cutting-lever D, causing the knife 13 to ap proach and pass the stationary cutting-edge in, causing the link wound off from the wile or rod L to be out off. W'ith the outward movement of the main arm d of the cutting lever D the holdingbar Q, will be brought forward by the transverscly-arranged bar 1?, so that as the knife i passes the stationary cutting cdge m the link N will be grasped and firmly held between the knife 2' and the end a of the holdingbar Q. At this time the concentric surface 0 of the cam 0 will have reached the arm (1 of the cutting-lever D, so that while this concentric surface 0 of the cam c is passing the lever D the knife t and bar Q, will re main at rest, holding the link. At the time the link is cut, or a little before, the cam e on wheel 0 will depress the end 6 of the lever G, which will elevate the opposite end of the said lever and cause it to raise the twister F in the collar R and to hold the twister above the link, and during the interval of rest of the bars D and Q and knife z while they hold the link the cam 0 will pass the end 6' of thelever G, which will permit the twister F to drop down in the collar B, so that the claw q of the twister will rest upon and engage with the folded end ofthe link, as shown clearly in Fig. \Vhile the twister remains in this position, engaging the link, the rack (1, formed upon the large wheel 0, will come in contact with the teeth act the hell-crank E, causing the bell-crank, acting through the connectingrod V. lever U, and collar It, to give the twister F a one quarter turn, which will put the required twist in the link. This being accomplished, the cam-face 0 will have passed the main arm (I of the cutting-lever D, whereupon the spring 0 will bring the lever D, plate I and holdingplate Q, back to the original positions, the finished link falling of its own weight into a box placed beneath the machine, and the instant the cam 0 passes the arm (l of the lever D the rack (I will release the bell-crank lever E, whereupon the spring \V will act to return the bell-crank, collar It, and twister F to their original position, ready to repeat the operation. There will be several mandrels K, of different sizes, with each machine, and the mandrels will be interchangeable with each other, so that links of various sizes may be made upon the same machine. The end of the main arm d" of the lever D is supported upon the bridge or arm A", forming a part of the main frame A, which arm guides the cutting-lever in its movement and takes the down-thrust of the cam c, and the end of this arm (1 is provided with the roller (1 to take the friction of the cam c. The stationary cutter and guide M is tempered its whole length, and is so held in the machine that it may be readily taken out and ground and properly adjusted back in the machine,so that a perfectly square and smooth out of the links may always be effected, insuring a perbination with the disk J, made fast to the shaft,

and the gear-wheel I, placed loosely upon the shaft, the disk and gear wheel being provided with clutching and releasing mechanism, whereby continuous rotary motion of the gear-wheel I will impart an intermittent rotary motion to the disk, shaft, and mandrel, substantially as and for the purposes set forth.
