V Machines, of which the following is a specification, reference being bad to the accompanying drawings, in which-.

Figure 1 is a side view of mymachine. Fig. 2 is a vertical central lengthwise section of the machine. Fig. 3 is a vertical cross-section of the swaging-head on line 3 3 of Fig. 2. Fig. 4 is a vertical cross-section taken through the line 4 4 of Fig. 2. Fig. 5 is anelevation partly in section and shows the stop-motion. Fig. 6 is a view, partly in cross-section, of the casting B and the fingers I). Fig. 7 is a top plan view of the machine. Fig. 8 is a plan view of spoke-wire WV, showingblanks and swaged portion. Fig. 9 shows cross-section of the rollerbushing 12 Fig. 10 shows roller b Like letters refer to like parts throughout the several views.

In the drawings illustrating the principle of my invention and the best mode now known to me of applyingthat principle (see Figs. 1 and 2) the standardj A supports the casting B, which is the outer casing of the swaging device and is firmlyheld to LhesupportA by the cap A and the bolts a a and nuts a a or in any other suitable manner. 5 The standards and frame A support the working parts of the feeding and shearing devices described below. I l 1 G is a driving-pulley splinedat g on the hub g of the fly-wheel G, and" G is a loose pulley on the same hub g. The fly-wheel G, through its hub g, is fast on head-shaft H, through the center of which and for its entire length is drilled a wire-passage h of suitable diameter to allow the passage of the wire to be operated-upon. The inner end of the wire-passage h is preferably contracted to the diameter of the wire W in order to guide it properly to the swaging-dies J B is a steel band shrunk on the inner end of easing B over the fingers b to increase the resistance of fingers b to the force of the hammering and swaging blows and to reinforce the blocks 1).

The stationary headorcasing'B, contain- (See Fig. 3.) Head-shaft H (see Fig. 2) projects into said chamber b and is provided at its inner end with a boss h, grooved at 77. across its inner face, the opposite sides of the groove being equidistant from the mid- ,dle of theboss h and coincident with the lengthwise axis of head-shaft H. The boss 72. {is recesseduat the middle of its front face to receive the bushing 75*, which is set loosely in. an annular opening therein provided. The hammers J, the wedges J and the swag'ingdies J 2 are looselyfmounte d in grooves ii? of the boss h, the hammers J and dies J being actuated by the successive contact of the camshaped ends j ofthe hammers J .with the inwardly-projectingperipheries of the rollers 6 .The' wedges are actuated by mechanism hereinafter described.

The reinforcing-blocksb, thei'bushing b the rollers 5 the'hamniers J the wedges J, the swaging-dies J {and the head-shaft bushing 71. are allsubject to rapid wear and require to bereplaced with more or less frequency. To facilitate the substitution of worn parts, the elements 3 ust above mentioned are removable and are retained in theirrespective positions by concentricface plates b -and 1),

plate 12 being removablyfixed' to head B and plate I) beingremovably fixed to the collar or boss h and rotating therewith and having suitable holes orslots b for the'reciprocation therethrough of the wedges-l; To regulate the force of the eredlbythe hammers J upon-the dies'J I provide tapered wedges J inserted between the "hammers J and the dies. J2, pi votally connected with the grooved revoluble collar K, which has backward and forward motion upon the collar-stud K, the said stud K being a part of the frame A and operatively conblows delivneeted on the frame with relation to the rotating boss la. The collar K is actuated by the lever K which is pivotally connected at with the cam-lever K The cam-lever K is fulcrummed at k on collar-stud K. The cam-lever K is provided with a cam-roller k which works with the cam K. The wedges J are forced inwardly between the hammers J and the swaging-dies J by the movement of the collar or wedge-carrier K toward the boss it, this movement being due to the push of cam K on the cam-roll 70 WVhen the portion 70 of cam K is against the cam-roll 76*, the spring K serves to pull the wed ge-carrier K and Wedges J outwardly from their most effective wedging position, so that the camshaped ends j of the hammers J are out of working contact with the rollers 12 One end of spring K is fast to frame A and the other end to cam-lever K and the spring is distended when the inward movement of the wedge-carrier occurs.

Cam-lever K is provided with a suitable device K (conveniently a turnbuckle) to increase or decrease its length, so that a proper adjustment is secured for the insertion or withdrawal of the wedges J between the hammers J and the dies J The cam K and a cam K and a worm-gear K are each supported on shaft K, which is actuated through the worm K (see Fig. 8,) the shaft K, which carries the worm K passing through suitable bearings in the frame A and the standard A and being provided with suitable drivingpulleys K and K. These pulleys are of different diameters to secure different speeds for shaft K and are each mounted on a hub K loose on the shaft K, which is adapted to be coupled to the hub K, which is fast on shaft K Cam-shaft K (see Figs. 2, 4, and 5) carries a rocker-arm K, which has a lengthwise slot 70 in which there is an adjusting-block hf, which is adjusted in its slot by the adj ustingscrew L. This block 70 is pivotally connected by a pin Z with a slide-block L, mounted in the lengthwise slot Z of the rocker-lever L which is pivoted at Z to the base of the niachine. The upper end of rocker-lever L is loosely jointed at Z with the connectingrod L for carriage D. That end of the rocker-leverL with which the connectingrod L is thus connected is furnished with a lengthwise opening I, in which a spring Z is mounted rearwardly of the pin Z The other end of the connecting-rod L is adjustably connected to the carriage by means of the clamp-bolt Z through the elongated slot Z By this adjustment the position of the carriage in relation to the wire is regulated independently of the adjustment of the slidebloek L. an abutment Z which on the back stroke of the rocker-lever L strikes slide-bar L carrying an inclined shoe Z", which cooperates with the inclined block Z in the vertical Rocker-lever L is provided with slide-bar Z and serves to pull the slide-bar Z downwardly against the stress of a spring Z mounted above the horizontal abutment Z through which the slide bar or rod Z passes, the rod being provided with a fixed collar Z to engage the upper end of the spring I. The upper end of the slide-rod Z extends into the path of an abutment Z on the bottom of the carriage D. On the back stroke of the carriage the pin Z engages the spring .1 in the outer end of the connecting-rod L and compresses it slightly. As this spring is compressed the shoe l moves the slide-rod Z downwardly and out of the path of abutment Z so that the carriage D moves again and carries the wire which has been operated on and is still clamped by the jaws D D (on carriage D) a distance equal to that portion of the spoke which is called the blank. The carriage on its back stroke is first brought to rest by engagement of abutment Z with the upper end of the slide-rod l. It is at this time that the wire ceases to move lengthwise and that the swaging-dies J form the shoulder 00, (see Figs. 2 and 8,) the swagiugdies J acting during the interval that the wire is at rest to form anicely-finished shoulder m instead of a more or less imperfectlyformed shoulder, as would happen if the wire were moved continuously. The interval required for compressing the spring 1 and pulling the slide-bar 1 out of the path of abutment Z practically corresponds to the interval required to form the shoulder 00, and when the shoulder as is completed the carriage moves on to its outermost limit, the extent of this movement corresponding to the length of the blank.

The jaws D D are loosely pinned at their butt-ends to the upright d of carriage D, the free end of one jaw facing the free end of the other jaw and both jaws pointing toward the swaging mechanism. The range of movement of one of the jaws is limited by a stop 61', mounted in a bracket (1 of the carriage D. The other jaw, which is opposite its mate, is moved toward the wire to clamp it by the cam d on the end of rod 61, which carries a roll 61 that runs in the lengthwise raceway d of the vertically-movable frame (1 This frame 61 is guided in vertical ways 01 d in the frame A Frame d is provided with a dependent cam-roll (Z which works with the cam K When the cam K is in operative position, the frame 61 is at its lowest position, fallin g downward in its ways by gravity, and the under jaw D then gravitating away from the wire V. YVhen the swell of thecam K rises against and past cam-roll (Z frame d is lifted, carrying the under jaw D against the wire WV and clamping it against the upper jaw D The dependent cam-roll d is adjustable on the frame (F in order to suit wires of different diameters, the adj Listing-screw (1' serving, with the adjustable cam-roll (1 to regulate the jaws to wires of different diameters and also to so adjust the jaws that their working ends are operative on work kept central in relation to the swaging mechanism.

To secure any desired length of blank in a given length of spoke, carriage D is formed with a lengthwise slot d, and the upright d, to which the jaws D D are pivoted, is provided with a horizontal side plate (Z through which a clamp-bolt d passes into and th rough the slot d. Carriage D is provided with a horizontal slide-plate f, having a lengthwise slot f, through which a clampingscrew f 2 extends to lock the plate in adjusted position on the carriage. This plate f carries an uprightf, in which is mounted the wireguide f this guide having a hole through it for the passage of the wire W One of its functions is that of ashear-blade. The mov-' able member f of the shearing mechanism is a vertically-reciprocating bar having a hole through it for passage of the wire, and when the movable member slides upwardly, the wire being through the-hole in guide f and also through hole in member f the wire is cut off, as will be readily uuderst-ood. Outting member f is actuated by the rocker-leverf, fulcru med on a stud f on the carriage D. One arm of the rocker-lever f works in ahole in the movable cutting member ,1, and its outer end is provided with a roller f which runs in the raceway d of the vertically-movable frame (1 The up-and-down motions of this frame 61 effect the requisite reciprocations of the movable cutting mem: ber f Carriage D is movable lengthwise of th machine toward and away from the swaging mechanism and is mounted on ways (Z in frame A Considering the mechanism in the position shown in the drawings, it spoke is supposed to have been just severed at the middle of a. blank-section of the wire, the movable cutting memberf is just returned to its position of rest, and the jaws D D released from the wire, so that the carriage is free to carry the jaws and the severing mechanism toward the swaging mechanism, through which it is supposed the second of two continuous blanksections has j ust been drawn. These two continuous blank-sections are marked {r and m in Fig. 2. The carriage now moves back toward the swaging-head and the wedges enter inwardly between the hammers and dies to thefull extent provided and. the jaws pass over the wire, which passes outward through the coincident holes in the wire-guide f and the hole in the movable cutting memberf When the carriage reaches the limit of its inward movement, jaws D D seize at or nearly on the swaged portion of the wire and at the same instant the shearing device is actuated and severs the spoke just pulled through by the feeding device, and the carriage now moves back with the wire, which is being constantlyhammered orswaged as it is pulled through the swaging mechanism, until. they abutment Z strikes the stop or slide rod I. Then, as above described, the carriage takes a fresh start rearwardly and the swaging-dies stop work, allowing the formation of two continuous blanks. The jaws are again opened, and the carriage moves inwardly to grasp and pull another spoke.

The main advantages of the herein-described machine are the simplicity of the construction of the swaging-head, permitting quick and easy renewal of worn parts and the momentary stopping of the carriage while the second shoulder is being formed and the subsequent completion of the back stroke of the carriage at the same rate of speed that it had at the first part of its rearwardmovement. carriage has been accelerated just before the second shoulder was finished, with the result that the wire was carried too swiftly to perl-Ieretofore the final movement of the mit proper swaging of the spoke about an inch in front of the second shoulder, this part of the spokes heretofore swaged being characterized by a rough or ridge-like conformation, deemed highly objectionable by those skilled in the art.
