Toall whom it may concern:
Be it known that I, ALVIN W. NEEDHAM, a citizen of theUnited States, residing at Detroit, in the countyof Wayne and State of Michigan, have invented certain new and useful Improvements in Machines for the Mannfacture of Core-Supports, of which the following is a specification.
My invention relates to a machine designed for the manufacture of core-supports at one operation. These coresupports, chaplets,or anchors, as they are variously termed, have heretofore been made by machinery, but generally upon two or more machines, each performing one or more distinct operations, and rendering necessary the assemblage of the parts of the chaplet by hand. Under the present construction, the chaplet is made complete at one operation in one machine.
In the d'rawings,Figure 1 is a top plan viewof a machine embodying in its simplest form the principles of my invention; Fig. 2, a side-view of the same; Figs. 3, 4, 5 and 6, views illustrating certain details hereinafter referred to; and Fig. 7, perspective and side views of the chaplet or core support.
The chaplet or core support comprises a stem or shank a, nicked at or near one end, and a head or disk 0. which fits upon the opposite end of the stem; the said stem being headed or upset above and below the disk as shown in Fig. 7.
.7 In Figs. 1 and 2 A represents the main frame or bed of the machine, on one end of which is mounted a shaft B carrying a band pulley O and a balance wheel D. Extending at right angles to shaft B i a second shaft E, which is provided with ab vel pinion b to mesh with a similar pinion c on shaft B, as shown in Figs. 1 and 2. Shaft B is provided with a cam cl which is designed to impart' motion to any suitable wire or rod feeding devices F, through the levere and link or rod f. The wire or rod-feeding devices may be constructed in any suitable manner so long as they are adapted to impart an intermittent or step-by-step feed to the rod or wire g which will preferably bewound upon a reel h.
The wire g, which forms the stem or shank of the chaplet, is fed from the reel 72. at the side of. the machine and passes to the nicking deviceor nicker G, shown in'Fig. 1. This device comprises a stationary nicking die 11, a movable nicking die j, and aframe or block it which serves not only to support the dies 11 and j, but also to guide and support the wire. The die j is carried by a rod or bar I, which is reciprocated toward and from the stationary die 1' and at right angles to the line of feed of the wire, by means of a cam m which latter, as shown in Figs. 1 and 2, is secured to shaft E. The nicking mechanism G is de-, signed to be adjusted relatively to the bed or frame for a purpose presently explained. The wire after being nicked, is passed through a reciprocating plunger H, which is actuated by a cam 12. on shaft E, as shown in Fig. 1. This plunger H, shown in Fig. 5, is
slotted at its end to form two yielding arms 0 0 between which is held the removable die 10.
Die p is provided with a hole or opening q to receive the wire 9 as it passes from the nicker, and is designed to act, in conjunction with a fixed die-block I, as a cutter, to the wire or rod'into pieces of predetermined lengths; that portion 7' of the die block I which is directly opposite the plunger H being offset as shown in Figs. 1 and 3, so as to form a sharp cutting edge 8. Now, the wire being passed through the hole q, projects a predetermined distance beyond the side of the plunger, as shown in Fig. 1. The cam at now moves the plunger inward toward the fixed block I and carries the projecting end of the wire against the sharp edge 3, where the wire is severed. That portion of the stock from which the piece is cut, remains-in the hole q, while the severed portion is held against the die block by a plunger or die J, as shown in detail in Fig. 6. The die block I and the plunger J are provided respectively with semicircular grooves t and it, which are enlarged at one end as at 'v, the construction being such that when the plunger J is moved inward against the die block I, the grooves t u will form a channel to receive and hold the severed section of the wire- Plunger J is actuto be understood as limiting myself to this construction, which is merely illustrative.
The die block I is provided on that uprightface which is at right angles to the face containing groove t,with a hole or female diey, and a sharp cutter or cutting die 2, as clearly shown in Fig. Moving in a right line toward and from these dies y and z, is a plunger or head K which carries a male punching die I), a cutter or cutting die and aheader or upsetting die 01; the said plunger being actuated by means of a cam -L secured to shaft B as shown in Fig. 1.
Secured to shaft B is another cam or eccen tric M which is designed to actuate a gripping or clamping plunger N arranged by the Y sideof the plunger K,said plunger N being held in contact with the cam by means of a spring 0, see Fig. 1. Plunger N is adapted to move periodically toward and from the block'I, to clamp and to release the stock or strip P of hoop iron used in forming the disk of the chaplet, the said strip P being unwound from a reel Q and fed edgewise into the machine at right angles to'the line of feed of the wire stock. In order to cause the proper feed ofthe strip P, any suitable feeding devices may be employed. In Fig. 1, I have shown a very simple arrangement comprising twov rollers R and S, one of which is actuated intermittently by means of an arm T mounted loosely upon the axis of the roll and carrying a pawl to engage a ratchet wheel; a reciprocating motion being imparted to the arm T through rod U, and a cam V on the shaft E.
The operation of the machine is as follows: The shafts Band E are set in motion and by means of the earns 01 and V, the rod and strip feeding mechanisms are put into action. The rod or wire g passing through the nickerG will be'nicked as shown in Fig. 7, and the end of the wire passed through the hole- (1 in the plunger H with-the said-end projecting from the right.hand side of said plunger a distance equal to the length of the stem or shank desired. 'lhe plungers H and J begin to move inward toward stationary block I, and while the projecting end of the wire is being severed, the plunger J in connection with the stationary block 1, holds the wire in the channel formed by the groovest and u, and retainsits hold upon the severed shank during the heading. During the operation of these devices, the strip-feeding devices have been at work, and have fed the strip P to such point as to cover the female die y on block I. As soon as this point is reached, the clamping plunger N moves inward'and holds the strip against the face of block I while the plunger K. also moves inward. The said plunger K which carries the 'male punch or die I) moves up to the strip, and allows the punch 12' to puncture thelatter and form ahole to receive the end of the shank or stem. Plungers K and N now recede and free the strip so that the intermittently acting rollers R, S, may feed the strip forward the predetermined distance, in other words so far as to bring the hole or opening in the strip directly opposite the end of the wire shank held by the two part die I J. With the perforation in the v strip P opposite the end of the wire shank, and with the severed wire shank held by the two part die, the plunger Hreceues slightly so as to bring the wire stock back into line" with the severed section. Plungers N and K now advance, the plunger N grasps or clamps the strip against the die block I, and the tools of plunger K move upto the stock. The punch 1) makes a second hole (in the next head or disk) the cutter c severs enough metal from the strip to form a head or disk for the chaplet, while the heading die d upsets the wire stem or shank on both sides of the chaplet disk, as shown in Fig. 7, the upset metal running into the annular enlargement 'v of the two part die I J. Plungers J N and K now recede, and the operations are repeated continuously in order as above specified. By moving the cam m alon'g shaft E, and shifting the nicking devices G, the nick may be formed in the rod or stem at any point throughout its length.
I am aware that a machine for upsetting a rod upon opposite faces of a flat bar or plate has before been devised, and of course make no broad claim herein to a machine having these functions.
Having thus described my invention, I claim is- 1 In an organized machine fog the'manufacture of chaplets, the combination with wire feeding, cutting, and holding devices constituting a shank-forming mechanism; of stripperforating and feeding devices co-operatiug therewith to bring the perforated chaplet disk or head thus made over the end of the shank;
what
and a heading device for, upsetting the stem on each side oi; the head. I
2. In a machine of the class described, the combination with means forfeedingamod, cutting it into lengths, and holding the severed section; of means for feeding a stripand punching a hole therethrough; and a-plunger or bunter for upsetting the end of the severed wire; and for cutting 0E the strip.
3. In combination with a die or holder for the wire stem or'shank of a chaplet; a strip feeding mechanism; and a plunger provided with punch b, cutter c and a header d. 4. In combination with block I having the shoulder oredge s; the reciprocating-plunger H provided with a die block p which latter has hole or opening q.
having the yielding arms 9 o, and the remov-' able die 19 clamped therein.
6. In-combination with block I having cutting edge or die z, and female die y, the reciprocating plunger provided with male die b, and'cutting blade 0'.
In witness whereof I hereunto'set my hand in the presence of two witnesses.
