COMBINED WIRE SWAGING, HEADING, AND BENDING MACHINE;

SPECIFICATION forming part of Letters Patent No. 617,270, dated January 3, 1895.

Application filed August 6, 1896.

To all whom it may concern.-

Be it known that I, CHALKLEY B. BALD WIN, a citizen of the United States, residing in the city and county of Philadelphia,State of Pennsylvania, have invented a new and useful Improvement in a Combined Wire Swaging, Heading, and Bending Machine, which improvement is fully set forth in the followin g specification and accompanying drawings.

My invention consists of an improved construction of wire swaging, heading, and bending machine wherein the successive steps which have heretofore been performed by hand are performed mechanically and automatically, the finished product being especially applicable to the manufacture of spokes: for bicycle and other wheels.

It further consists of novel details of construction, all as will be hereinafter set forth, and specifically pointed out in the claims.

Figure 1 represents a plan View of a wire swaging, heading, and bending machine embodying my invention. Fig. 1 represents a perspective View of a portion of the mechanism for severing the wire. Fig. 2 represents a detached side elevation of a portion of the mechanism in which the heading and bending of the wire is accomplished. Fig. 3 represents an end elevation of Fig. 2. Fig. 4 represents a front elevation of that portion of the machine in which the swaging is done, showing the dies and the mechanism for operating the same and their adjuncts. Fig. 5 represents a section on line mm, Fig. 4:. Fig. 6 represents a plan View of Fig. 4, the upper pinion being removed. Fig. 7 represents a plan view of the gripping or clamping device by means of which the Wire is held and propelled after being severed by the proper mechanism. Fig. 8 represents a side elevation of Fig. 7, showing the clamping device for gripping the wire, the ratchet-Wheels employed, and the means for operating the same. Fig. 9 represents an end elevation of Fig. 8. Fig. 10 represents an end elevation of a portion of the right-hand end of Fig. 1, showing the mechanism whereby the clamping-jaws and mechanism seen in Figs. 7 to 9 are actuated and locked. Fig. 10 represents in detached Serial No. 601,876. (No model.)

position a perspective view of the notched and serrated disk seen in Fig. 10. represents a plan view of the left-hand portion of Fig. 1, showing the mechanism for feeding the wire. Fig. 12 represents an end elevation of Fig. 1. Fig. 13 represents a front elevation of the left-hand portion of Fig. 1. Fig. 14: represents a front elevation of a portion of Fig. 1, showing the carriers employed for removing the wire after it has been cut off to the clamping devices seen in Figs. 7 to 9, inclusive. Fig.15 represents an end elevation of Fig. 14, partiallyin section. Fig. 16 represents in elevation a portion of the ratchet mechanism seen in Fig. whereby the ratchet-wheels seenin Figs.7 to 9 are actuated. Fig. 17 represents a plan View of a portion of Fig. 15, showing the means employed for holding and propelling the wire after the same has been severed. Figs. 18 and 19 represent on an enlarged scale a plan View of a spoke, showing the relative position of the holding and. bending dies thereto, the finished spoke being shown in Fig. 19. Figs. 20 and 21 represent on an enlarged scale sectional views showing the dififerent positions the locking device for the swaging mechanism assumes.

Similar numerals of reference indicate corresponding parts in the several figures.

Referring to the drawings, first to the lefthand portion of Fig. 1 and Figs. 11 to 13, inclusive, 1 designates a portion of the bed of the machine upon which the stationary block 2 is supported, said block being provided with a ledge 3, upon which the wire 4 is adapted to rest, said wire being held in position by means of the eccentric or cam 5, which is pivoted above said ledge, as will be understood from Fig. 13, so that it will permit the'wire to be readily fed or moved in one direct-ion, as toward the operative parts of the machine,but will prevent its return in the opposite direction.

6 desi nates a movable block which is provided with suitable ways in the bed or housing of the machine, said block being also provided with a ledge or offset portion, upon which the wire 4: rests, andhaving a plurality Fig. 11

ledge and are adapted to grip and propel the wire when the block 6 is moved to the left of the position seen in Fig. 13.

8 designates a pin projecting from the block 6 and engaging the walls of the slot 9 in the lever 10. 11 designates a rock-shaft upon which said lever 10 is mounted, the same having a suitable bearing 11 12 designates an arm which is attached to said shaft 11 and has a suitable connection to a connecting-rod 13, which latter has an end pivotally attached to the knuckle 14, which has a pin 15 in engagement therewith, whose head is adapted to slide in the walls of the groove 16, which latter is located in the disk 17, it being of course understood that the knuckle is adjustable relative to the slot 16 and that if desired a ball and socket and connections may be employed in place of those shown.

18 designates a shaft upon which the disk 17 is mounted, the same being provided with suitable bearings in the housing or framework of the machine.

19 designates a gear mounted on the shaft 18, which is in mesh with the pinion 20, which is mounted on the shaft 21, which latter is provided with suitable bearings.

22 designates a pulley mounted on the shaft 21, to which power maybe applied in any convenient manner.

Referring now to the left-hand portion of Fig. 1 and to Figs. 4 to 6, inclusive, 23 designates a pulley which revolves in the present instance independently of the pulley 22 and is mounted on the shaft 24, which latter has the longitudinal passage 25 therein, through which the wire 4 is adapted to be fed.

26 designates the upperand lower dies, each mounted in the head 27, said dies being held in position by means of the ways 28 and each having lugs 28 in engagement with a spring 29 so that the dies are normally held apart from each other. 29 designates adjusting-screws common to each of said dies and to a suitable portion of the heads 27, whereby the position of said dies relative to each other can be varied when desired.

30 designates rollers journaled near the extremity of each head 27, said rollers being in contact with the corrugated periphery 31 of each of the disks 32, which are each secured to a shaft 33, which revolves loosely near the extremities of the bar 34, which latter is secured to the shaft 24, as will be evident from Fig. 5.

35 designates pinions which are mounted on the shafts 33 so as to revolve in unison therewith, said pinions meshing with the gear 36, which is loosely mounted upon a suitable bearing on the shaft24.

37 designates a block which slides in suitable ways in the bearing of the shaft 24, said block contacting with the head 38 of the bolt 42, against which head abuts one end of the spring 39, the other end of thelatter contacting with the shoulder 40 of the recess 4O in the hub 41 of the gear 30, through which hub the bolt 42 passes, the extremity of said bolt being adapted to engage a cavity 43 in the bar 34-, the relative extreme positions the bolt may assume being indicated in Figs. 20 and 21, and the operation being as follows: The pul1ey23 revolving continuously causes the shaft 24 and the bar 34 to rotate .in unison therewith. The block 37 is reciprocated atthe proper intervals, and it will be evident from Fig. 21 that when the parts are in the position therein shown the head 38 has a portion in engagement with the recess 40 ,while the rest of said head is in engagement with its bearing 38 the gear 36 being now locked and immovable, while the bar 34 is permitted to rotate freely in unison with the shaft 24, thereby causing the pinions 35 to rotate and thus actuate the dies 26, thereby effecting the swaging, as is evident. VVhen the spoke or other article has been swaged to the desired degree, the block 37 is caused to reciprocate to the left of the position seen in Fig. 21 to the position seen in Fig. 20, and since the end of the bolt 42 is now in engagement with the cavity 43 of the bar 34 the gear 36 will be caused to rotate in unison with said bar, and the pinions 35 having ceased their rotation the dies 26 are immovable with respect to each other, and the swaging operation ceases until the parts assume the position seen in Fig. 21 again.

44 designates a lever which is fulcrumed at 45 to a suitable point and has one end pivoted to the block 37, while its other end 47 is adapted to cont-act with the cam 48, (seen in Fig. 1,) which latter is mounted upon the shaft 18, said lever 44 being always held in the proper position by means of the spring 46, which has one end attached to a suitable portion of the housing, while its free end bears upon said lever.

It will of course be understood that by giving the proper configuration to the cam 48 the swaging operation can be suspended for a sufficient period to enable the wire to be fed through the swaging mechanism to the desired extent after a spoke has been swaged; but as the construction of cams and their adjuncts is a matter of machine design I have not deemed it necessary to describe the same in detail.

The device for cutting off the wire at the proper intervals is'best seen in Figs. 1 and 1, the preferred form being the lever 49, which reciprocates in suitable guides and has its end 50 provided with a yoke and a pin 51, projecting therefrom, which engages a cam-slot in the disk 52, which is mounted upon the shaft 18, whereby a proper reciprocating movement will be given to the lever 49, so that its cutting edge 53, as seen in Fig. 1, may engage a portion of the wire at the proper intervals. It will of course be evident that any other suitable cutting mechanism may be employed for severing the wire, and

I have therefore not shown the present construction in detail, as I do not wish to be limited to any one device for this purpose.

The wire having been cut off, the carriers or means for removing the same to the clam p-.

ing or gripping mechanism will next be described, reference being had to Figs. 1, 14, and 15.

54 designates brackets or bearings which may be attached to a suitable portion of the housing of the machine, in which bearings the rock-shaft 55 is mounted, the latter being provided with the rock-arm 56, which. has pivotally attached thereto one end of the lever 57, while the other end of the latterhas a connection with the crank-pin 58, which is attached to the gear 19, whereby it will be seen that as said gear revolves a rocking motion will be imparted to the shaft 55.

59 designates a plurality of arms which are secured to the shaft 55 in any suitable manner so as to rock in unison therewith, the upper portion of said arms having pivoted thereto a knuckle or block 60, through which the rod 61 passes, the position of which latter with respect to the block being adjusted by means of the set-screw 62. l

63 designates one member of the wire-carrying device, (best seen in Figs. 15 and 17,) said member being provided with a shoulder 64 and the forwardly-projecting finger 65.

66 designates a tongue or member which is pivotally mounted in the member 63 by means of the pin 67 and is pressed downwardly by means of the spring 68, so that its forward end engages the wire 4, whereby the latter will be positively held, as indicated in Fig. 15, between the said

members

63 and 66 during the forward movement of the arms 59.

69 designates a depression or seat between the

plates

70 and 71, into which the wire 4 is fed prior to its removal, it being of course understood that when the arms 59 move to the left of the position seen in Fig. 15 the

members

63 and 66 first ride over the wire 4 and then drop sufficiently to allow their forward portions to engage the wire and to move it from the position seen at the left of Fig. 15 to the position seen at the right of Fig. 15.

The wire having been cut off and moved by means of the carriers 63 to the position seen at the right of Fig. 15 is propelled into the gripping mechanism 72,the detailed construction of which will be understood from Figs.

7 to 9, inclusive.

73 designates the body portion of the gripping mechanism, the same terminating at each end in the

jaws

74 and 75.

76 designates members pivotally mounted upon the body 73, each of which has a jaw 75, above referred to, which acts in conjunction with said jaw 74, said member 76 being pivoted at the point 77 to the body 73.

7 8 designates rollers which are mounted upon the members 76 at the end opposite to the jaws 7 5, said rollers being engaged at the proper intervals by either the elevation 79 or the depression 80 of the ratchet-wheel 7 8, which, it will be understood is loosely mounted upon the shaft 93, while the gripping-jaws are fast on said shaft.

81 designates shoulders formed upon the ratchet-wheel 78 which are adapted to be engaged by the pawl 82, the latter being best seen in Figs. 8, 15, and 16, and it being noted that when one enlarged portion or cam-face 79 of the ratchet-wheel 78 is in contact with one of the rollers 78, as indicated at the top of Fig. 8, the depression 80, which issubstantially diametrically opposite thereto, as indicated also in said Fig. 8, will be in contact with the opposite roller 78, so that when one of said jaws is closed the other will be open, as in the present instance the right-

hand jaws

74 and 75 are closed and gripping the wire, while the left-hand jaws are opened, as will be evident from Fig. 8. Any suitable means may be employed for keeping the jaws normally open, as a spring 7 5 The pawl or dog 2 is adjustably mounted on the arm 86, which is pivoted by a pin 85 to the arm 83 of the shaft 87, which latter is provided with suitable bearings 87*.

88 designates a rock-arm attached to the shaft 87, to which arm is secured one end of the lever 89, the other end of the latter being reciprocated by means of a pin engaging a cam 89 on the shaft 18 or by any other suit able mechanism actuated by said shaft 18.

90 designates a spring which has one end attached to a fixed point 91, while its other end pulls upon the lower extremity 92 of the lever 86, so that the pawl 82 will be caused to normally move in the direction of its arrow so as always to engage the shoulder 81 of the ratchet-wheel 78*, as seen in Figs. 8 and 15.

The shaft 93, which, it willbe remembered, has the gripping

members

73 and 76 mounted fast thereupon and the ratchetwvheels 78 mounted loosely thereupon, is provided with suitable bearings in the housing of the machine and has also mounted thereupon the disk 94,which latter is provided in the present instance with four recesses 95, which are substantially diametrically opposite to each other, as will be understood from Fig. 16.

96 designates a series of teeth or projections which are located upon the side of the disk 94, which are adapted to be engaged at the proper interval by means of the latch 96 which is pivoted to the arm 97, which latter is mounted upon the shaft 93 so as to oscillate freely thereupon, said arm having a camface 98, which is adapted to contact with the roller 93 of the arm 10, at proper intervals, thereby disengaging the nose of the lever 107 from the adjacent notch 95 when the arm 97 is actuated in the proper direction.

99 designates a pin by means of which connection is had between the arm 97 and the knuckle 100, the latter being adj ustably connected to an end of the connecting-rod 101, the other end of the latter engaging the crankpin 192, which is mounted upon the disk 103,

the latter being attached to the shaft 104, which rotates in suitable bearings.

designates a pinion which is mounted upon the shaft 104, said pinion being in mesh with the gear 106, which is mounted upon the shaft 18, to which power is transmitted through the medium of the gear 19, the pinion 20, the shaft 21, and the belt-pulley 22.

The lever 107 is pivotally mounted at 108 to a suitable portion of the framework or housing 109, said lever being provided at its point of attachment to said housing with a suitable adjusting device 108 108 designates the nose or dog, which is attached to the end of the lever 107 and is adapted to engage and lock the proper notch or recess 95 at the proper intervals, as will be hereinafter explained, it being evident that the movement of the disk 94 is caused by the engagement of the latch on the arm 97 with the proper tooth 96, while the disk is held in locked position for the required length of time through the medium of the dog 108 of the lever 107, the proper movement being imparted to the lever 107 by means of the connecting-rod 101, and the lever 107 being held in position by means of the spring 107 Referring now to Figs. 2 and 3, the mechanism for holding the wire during the operation of heading the same will now be described.

109 designates upper and lower jaws, the lower jaw being stationary or fixed, while the upper jaw is attached to the lever 111, which is fulcrumed at 112 to any suit-able fixed point, said jaws being guided and adjusted relative to each other in any suitable manner.

113 designates a friction-roller which is mounted on the pin 113, said roller being in contact With the cam 114, which latter is mounted upon the shaft 18, it being evident that at the proper interval the action of the cam 114 upon the roller 113 will cause the lever 111 to be operated, thereby moving the upper jaw 109 toward the lower stationary jaw, and thus tightly gripping the wire 4, as indicated in Fig. 3. The wire being now rigidly held, the die 115 is caused to impact against the end of said wire owing to the re ciprocation of the movable block 116, which has its bearing in the head 116 the extremity of the block 116 terminating adjacent the bolt or threaded stem 117, which passes through an end of the lever 118, which is f ulcrumed at a suitable fixed point 119, the end 120 of said lever being provided with a roller 121, which is adapted to contact with the working face of the cam 122, which is mounted on the shaft 18, through the medium of the spring 123, while the block 116 is held in its proper relative position through the medium of the spring 124, wherefrom it will be evident that sufficient compression will be exerted upon the end of the wire so that the head will be formed, the reduced portion or neck 26 having already been formed through the medium of the mechanism seen in Figs. 4 to 6, as is evident, and the wire or spoke appearing now as in Fig. 18, it being of course understood that the wire 4 has all the time been gripped in the proper jaws of the gripping mechanism. (Seen in Figs. 7 to 9.) The gripping mechanism 72 is now caused to revolve by the mechanism seen in Fig. 10 to the position seen in Fig. 1, in which the final steps are performed.

126 designates the anvil, against which the portion 4 of the nearly-completed spoke is adapted to be held during the final steps.

127 designates a head movable in suitable Ways and provided with a roller 128, which is adapted to contact at the proper intervals with the cam or projection 129, which is mounted upon the shaft 18. 130 designates a socket or cavity in said head, in which is seated a spring 131, one end of said spring bearing against the bottom of said cavity, while the other end contacts with the movable die 132, said head 127 carrying also the rigid die 133. The action of the aforesaid dies will be understood from Figs. 2, 18, and 19, from which it will be evident that after the initial advancement of the head 127 and the die 132 the latter will hold the portion 4 tightly against the anvil 126, after which a further movement of said head 127 will cause the die 133 to contact with the spoke near the head 125, thereby bending the same into the position seen in Fig. 19, the return movement of the head 127 being insured by the contact of the spring 135 with the lug 134, attached to said head, whereby the roller 128 is caused to always be in proper contact with its cam.

The detailed operation in the successive steps of manufacture is as follows: The rotation of the shaft 18 and the disk 17 imparts a rocking motion to the lever 10, thereby propelling the wire into the swaging mechanism, as will be understood from Fig. 13. The operation of the swaging-machine is rendered intermittent by the reciprocation of the block 37, (seen in Figs. 5, 20, and 21,) as has already been explained, said block being reciprocated at the proper intervals by means of the lever 44, which latter is operated by the cam 48, mounted on the shaft 18, it being understood that the operation of swaging is interrupted long enough for the spoke after being swaged to be propelled the desired distance. The swaged wire is next cut at the proper point by means of the cutting device. (Seen in Figs. 1 and 1.) in Figs. 14 and 15) then propel the swaged wire into the gripping device, (seen in Figs. 7 to 9,) which latter is rotated in unison with the shaft 93 through the medium of the mechanism best seen in Fig. 10, the jaws of the gripping mechanism being locked and unlocked at the proper intervals by means of the paWl-and-ratchet mechanism, (seen in Figs. 15 and 16,) the arms 86 and pawls 82 being raised at the proper intervals by the movement of the lever 89, which latter is actuated by the cam 89 while the spring 90 causes the pawl to always properly engage its ratchet- The carriers (seen IIC wheel. WVhen the jaws holding the wire are in a substantially upright position, said wire is headed by the mechanism seen in Figs. 1, 2, and 3, the lever 118 being thrown into operation by the cam 122, while the swaged spoke is tightly gripped between the jaws 109 the cam 114: having now raised the lever 111, so as to bring the upper jaw into juxtaposition with the lower one. The disk 94, carrying with it the shaft 93, will next be caused to make a quarter of a revolution and the wire 4 will be brought into the position seen in Fig. 1, at which period the head 125 of the swaged spoke will be bent from the position seen in Fig. 18 to the position seen in Figs. 1 and 19, the head 127 being actuated by the contact of the cam 129 with the roller 128, the operation of the dies carried by said head being evident from said Figs. 18 and 19, and all the steps having been accomplished the final product will appear, as indicated in said Fig. 19, the jaws holding the finished spoke being now caused to open and said spoke being received in any suitable receptacle.

It will of course be apparent that certain of the parts can be made adjustable according to requirements and that various changes can be made in the structure of the cams and other similar devices and the manner of assembling the same which will come within the scope of my invention, and I do not, therefore, desire to be restricted in every instance to the exact construction I have herein shown and described.

The action of the swaging device can be varied by adjusting or interchanging the gears and disks employed or by properly manipulating the adj usting-screws, while the extent of the feed can be varied by adjusting the knuckle 14L relatively to its slot 16, as will be understood from Fig. 12.
