WILLIAM H. WIGGIN, OF WORCESTER, MASSACHUSETTS, ASSIGNOR TO THE MARCUS MASON MANUFACTURING COMPANY, OF NEV YORK.

SPECIFICATION forming part of Letters Patent No. 565,821, dated August 11, 1896.` Application led May 9, 1896. Serial No. 5901851. (No model.)

To all whom t may concern.-

Be it known that I, WTLLIAM H; WIGGIN, a citizen of the United States, residing at Worcester, county of Worcester, State of Massachusetts, have invented certain new and useful Improvements in iVire-Swaging Machines, of which the followingis a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to wire-swaging machines employed to compress `wire in the formation of bicycle-spokes, needles, and analogous articles; and the primary object of my invention is to provide a machine to simultaneously compress more than a single piece of wire and thereby to enlarge the capacity of a machine of this class; and my invention has the further objects of conducing the durability of the operative parts of the machine, accurately controlling during the operation of the machine the degree of action of the swaging-dies upon the wire, and effecting the relief of the wire from the action of said dies when desired.

My invention consists, primarily, in the combination, in a wire-swaging machine, with pairs of swaging-dies, of a support common to and seated and movable between opposed faces of the anvil members of said pairs of dies and adapted to sustain said anvil members at different distances apart from each other,l together with actuating mechanism adapted to impart swaging movement to the reciprocating members of said pairs of dies; and my invention comprises the several parts and devices in a machine of this class, hereinafter shown and described, as the same are constructed and combined to operatein the manner hereinafter set forth and as the same are more particularly specified in the claims herein.

In the drawings, Figure l is a side elevation of a wire-swaging machine containing the several features of my invention. Fig. 2 is a front end elevation of the same. Fig. 3 is a side elevation of the stationary supporting-stand which I preferably employ to hold p Fig. 4 is a `plan of the same. Fig. 5 is afront end enlarged sectional elevation of the head carrying the mechanism for actuating the swaging-dies and the die-supporting frame, taken on line 5 5 of Figs. 3 and 4. Fig. 6 is an enlarged sectional plan of the same parts, taken on line 6 6 of Fig. 2. Fig.- 7 is a diagrammatic plan of two pairs of swaging-dies in the die-supporting frame and followers at the outward faces of "the working members of said pairs of dies, together with a preferable form of the movable support seated between the opposed faces of the anvil members of said pairs of dies and mechanism connected to and operated l by said support and preferably employed in connection therewith to effect the adjustment relatively to each other and to sustain in such adjusted position the anvil members of said pairs of dies in conformity to my invention; and Fig. 8 is a lateral section of the device preferably employed to operatively conneet anvil-blocks to the said movable support for the purposes of the invention.

In the drawings, l indicates the main frame or standard of the machine, upon which the voperative parts are mounted.

At 4 is shown a head comprising a recessed shell 4a, in which are carried the cams 7 for actuating the swaging-dies. For the purposes of the principal feature of the invention it is preferable that this head is revoluble, and tol accomplish this it may be mounted on the end of a shaft 2, having bearings on the machine-frame and provided with a driving-pulley-3, as shown.

` The head 4 is preferably constructed with a ring 5 Within theshell 4, and provided with transverse grooves 6, in which are fitted the cam-blocks 7, provided with stems 8, which extend radially through said ring and shell and have their outward ends threaded to severally receive nuts 9, which serve to draw the cam-blocks against the inward face of said ring and hold them in place in the respective transverse grooves therein.

' The die-supporting frame ll is preferably,

forthe purposes of the principal feature of` the invention, stationary inthe machine; and to accomplish this and to enable it to be seated within the circular range of described camblocks in the revoluble head 4 in position to enable the dies supported by it to be actuated by said camblocks and to be readily with-` IOO drawn from the head 4 or be unshipped of the machine the said supporting-frame may be conveniently mounted upon and project or overhang from the rearward edge of abaseplate 12, to which it may be reinforcedly united by ribs I3, the said frame and its baseplate and uniting-ribs being desirably cast in one piece, and such homogeneous structure being mounted on a suitable standard 10, fixed on the machine-frame in front of the head 4, as shown, with the frame 11 projected into the cam-ring in said head.

The die-supportin g frame is preferably seg mental in form, as shown, centrally recessed downwardly from its plane upward face to accommodate the swaging-dies and their hereinafter-described adj unctive mechanism, and t-he said recess may be closed by a cap 14, held to the plane face of the segmental frame by screws 15, while the frame is preferably provided with laterally-extended way-plates 3l and 32 in its recess, together with a back plate 49 and removable front plates 50 for the convenient seating therein of the herein* after-described swaging-dies.

In carrying out the primary feature of my invention I employ pairs of swaging-dies 48 and 4S, seated in the recessed frame 1l and preferably between the

wayplates

31 and 32 therein, anda support 33, seated and movable between the opposed faces of the anvil members 48b of said pairs of dies and adapted to sustain said anvil members at different disiances apart from each other, in conjunction with mechanism, which may be that hereinafter particularly shown and described, in operative engagement with the reciprocating members 48 of said pairs of dies and the range of actuating-cams 7, to impart, in connection with said cams, swaging movement to said working members of said pairs of dies.

In the machine illustrated in the drawings two pairs of swaging-dies are shown seated in the same horizontal plane between the

plates

31 and 32 in the recess in the frame Il, and it will be found desirable to employ this number of pairs of dies in a machine of this class in conforming to this principal feature of my invention. The movable support between the anvil members of the pairs of dies is preferably in the form of a wedge, as shown, capable of sliding movementin its seat in the direction parallel and desirably coincident with the axis of the head 4, and when employed in connection with two pairs of dies, as shown, the vertical sides of the wedge are the inclines, and its upper and lower faces may be parallel planes, while the anvil members aforesaid are provided with correspondinglyinclined faces opposed to the inclines on the wedge, by means of the anvil blocks hereinafter specified. The movement of the said wedge-support maybe effected, controlled, and its position relatively to the anvil members of the pairs of dies may conveniently be defined and fixed by means of a lever 37, pivoted in the machine-frame at 38, and one arm of which engages, as by a sector 36 thereon, meshing a rack 35 on the under face of the outer end of the wedge-support, while the other arm is in actuating engagement with a rock-'shaft 4l, as by a sector 39 on said arm of the lever meshing a pinion 40 on said shaft, the said rock-shaft being provided with an operative handlever 42, adapted to engage adjustable stops 43 and 431l on the machine-frame to limit and determine the movement thereof, and by means of these devices the movement of said wedge-support may be effected and controlled and its position ixedly adjusted during the operation of the swaging-dies.

At 44 and 45 are shown anvil-blocks which are desirably employed in a machine of this class, and are respectively interposed between the opposed faces of the anvil members of the pairs of dies and the support In the construction shown these anvil-blocks are respectively seated between the inclined faces of the wedge-support and the opposed faces of the anvil members of the pairs of dies, and the faces of the said anvil-blocks adjacent to the inclined faces of said wedgesupport are correspondingly inclined to fit thereto, as shown. The anvil -blocks are harnessed to the wedge-support, so that the movement of the support in one direction by its described actuating mechanism will throw the blocks away from each other and the movement of the support in the opposite direction will draw the blocks together, and this may be conveniently accomplished by means of plates 4G, attached to the upper and under faces of said blocks and reaching over the described upper and under faces of the wedge-support and provided with lips 47, entering grooves 34, formed in the said faces of the wedge-support, parallel, respectively, with the inclined side faces of said wedgesupport. It is evident that in this arrangement the oscillation of the rock-shaft 4I, and consequent vibration of the lever 37, and reciprocal movement of the wedge support will, by affecting the movement of the anvilblocks, as described, cause the anvil members of the pairs of dies to more or less approach or recede from the working members thereof, so that in this way the degree of action of the swaging-dies upon the wire they are compressing may be accurately controlled during the operation of the machine, or the entire relief of the wire from the action of said dies may be effected at pleasure.

The mechanism which I preferably employ in connection with the range of cam-blocks to actuate the dies comprises

levers

17 and 18, working in lateral recesses 16 in the die-sup porting frame, and respectively pivoted at -their upper and lower ends on

studs

19 and 20, and provided at their free ends with friction-rolls 2l, and governed by spring-actuated bolts 22 to vibrate the levers to carry their friction-rolls into the path of the cams 7, together with follower-

blocks

29 and 30, respec- IOC IIO

tively, carried by said

levers

17 and 18, and adapted to play in the central recess in the die-supporting frame and impinge upon the outward faces of the reciprocating members of the respective pairs of dies therein.

The actuating devices for the bolts 22 may conveniently be composed of the spiral springs 23, seated about said bolts in recesses in the machine-frame, and tension-adjusting bolts 24, acting upon the springs and controlled by nuts 25, which are adapted to be turned on their bolts by a Spanner, but are held from endwise movement within slots 26, as shown.

The follower-

blocks

29 and 30 may be conveniently seated between the

plates

31 and 32 in the die-supporting frame and may be respectively connected to the

levers

17 and 18 by links 28, seated at one end in semicircular recesses 27. in the levers and at their opposite ends in similar recesses in said blocks.

The hereinbefore-described front plates 50 on the recessed-die-supportin g frame are preferably provided with outwardly-flared lateral apertures 52, which severally inwardly register with the entrances to the matrices in the respective sectional swaging-dies, as shown, to readily guide the wire fed to the dies into said matrices, and the back plate 49 and rearward part of the frame 11 are provided with apertures 53, which register with the exits from the said matrices in said dies and fall within the internal diameter of the shaft 2, which is hollow for the purposes hereof, so that the wire may extend backward from thedics through said back plate and frame and into the hollow shaft.

The front plates 50 are desirably held in place between the

plates

31 and 32 by segmental-headed screws 51, seated near the ad-- jacent edges of the front faces of the

plates

31 and 32, respectively, so that by turning said screws to bring the plane portions of their segmental heads coincident with the said edges of said

plates

31 and 32 the plates 50 and the dies may be readily unseated and Withdrawn from the die-frame.

It will be understood that the die-trame herein shown and described, together with the head for holding the cams and the mechanism for operatively connecting the actuatingcams to the die-followers, as herein set forth, may be employed in connection with andto impart swaging movement to a single pair of dies; and it will be further understood that mechanism, such as is well known and employed for the purpose, may be used for holdl ing and feeding the wire to be swaged to the 4 provided on anvil-blocks interposed between said support and the anvil members of said pairs of dies, together with actuating mechanism adapted to impart swaging movement to the working members of said pairs of dies; substantially as and for the purpose specified.
