7 Claims. (Cl. 140-11) The invention relates to a machine for making metal clips and applying them to articles to be secured together. More particularly, it relates to a. machine for converting fiat blanks of metal or other suitable material into clips and bending them around the articles to be fastened thereby, with particular application to the assembling of the several elements of spring cushion elements. In the preferred form of the inventionthe clips are formed directly from continuous strip material.

In assembling the coil springs, tie wires, border wires and similar elements of upholstery spring assemblies and like structures, adjacent spring elements are commonly fastened together at their points of contact and are also fastened to tie and border wires. For this purpose there are often used small metal straps or clips which are bent around the wire elements to 'be held'together. Such clips are usually preformed or partially bent to shape and thereafter assembled on the parts to be joined and compressed or clinched by some suitable tool. These operations are obviously laborious and time consuming.

The principal objects of this invention are:

(a) To provide a machine for forming clips directly from continuous strip stock and applying them to the objects to be bound together;-

(b) To provide such a machine which forms and finishes the clips directly on the objects to which they are applied;

(c) To provide a semi-automatic clip forming and applying machine in which the operator has merely to insert and remove the elements to which the clips are applied and to operate a singlecontrol;

(d) To provide an electrically operated machine in which the sequence of necessary operations is carried out by automatic electrical controls;

(e) To provide novel clip forming and applying apparatus adapted for operation by any suitable source of reciprocating motion sequentially applied to the elements thereof;

(f) To provide a clip-forming machine which may be adjusted to form clips of different sizes;

(g) To provide strip-material feeding apparatus which will deliver a measured amount of stock to the clip-forming mechanism.

Other objects and advantages of the invention will in part appear and in part will be obvious from the detailed description of the present preferred embodiment of the invention.

The invention accordingly comprises the fea-- tures of construction, combination of elements,

General description clipped The mechanism which forms and applies the metal clips is supported beneath the table top in v and on a frame 24 to which is also attached a box -pling it to a similar pin 58 at the end. of the 25 in which some of the electrical apparatusis i enclosed. At the floor level in a convenient position for the operator, who stands or sits at the left side of the machine as shown in Fig. 8, is a foot switch Sl by which the machine is controlled. At the back of the machine is a bracket 28 holding a reel of metal strip 29 from which the clips are made.

On the right side of the machine (the front in Fig. 8) is a crank 38 for manually feeding the strip material into the clip forming mechanism when the machine is first started or when a new reel of material is inserted therein. In front of the operator, on the left side of Fig. 8, is a gear shift lever 3| which is used for changlower part of the clincher 4|. Thus the spring 49 serves to yieldingly hold the clinchers 48 and 4| in their retracted positions. The upper part of the clincher 48 is bifurcated so as to provide space for the bracket through which the pin 45 passes and so that a removable nose piece 52 may be inserted therein and held by means of the pins 54 and 55. The lower part of ing the gear ratio in the feeding mechanism to into the machine through a pair of guide rollers carried by the bracket 2, thence through the feed rollers 34 and 35 and across the guide 36 in which a die 38 reciprocates. The die moving upwardly cuts from the strip 29 a blank 39 (Fig. 2) from which the clip is formed. In its upward movement the die causes the blank to impinge upon the articles to be clipped together and since the die has a face formed with a central depression it bends the ends of the blank upwardly about the object, giving it a U-shape with upstanding wings on either side of the object as shown in Fig. 3.

A first clincher 48 moves up and down with the die and as the die completesits initial stroke the clincher is pushed inwardly as shown in Fig. 4 to bend down one of the wings of the partially formed clip. Following this the clincher 48 is retracted and while the die is still in raised position against the clip a second clincher 4| is pushed in from the opposite side to bend down the other wing of the clip as shown in Fig. into the final form shown in Fig. 6 or 15. The

clincher 4| is then withdrawn, the die and the first clincher 48 descend to their original position, the proper amount of strip material 29 is automatically fed into the guide36 and the machine is ready to repeat its cycle of operations. The movements of parts described above are brought about by means of the three solenoids A, B and C which are operated in properly timed sequence by the electrical mechanism hereinafter described.

Clip forming mechanism which are held against upward movement by the holding device 22. described in detail.

The guide 36 is secured in the table top, 28 and provides a bearing in-which the die 38 reciprocates. The die is connected to the plunger a of the solenoid A and is moved upwardly thereby. Connected to the die 38 is a bracket 44 on which the clincher 48 is pivoted by a pin 45 so that the die and clincher reciprocate together.

The clincher 48 is an arm which is solid in its lower part 46, through the end of which a pin 48 extends for attachment of a spring 49 cou- This mechanism will now be the nose piece 52 extends slightly beyond the clincher 48 so as to provide a bearin surface 54 against which presses the roller 58 attached to the middle pivot at the knee of a toggle-joint comprising the links 59 and 68. The upper link 59 is pivoted at 6| to a bracket 62 attached to the frame. The lower link 68 is pivoted at 64 to a cross member 65 fixed on the vertical shaft 66 and carries a roller 68 which bears against the face of a block 69. This block has a sloping face 18 which bears against a part of the frame having a similar slope and is held in place by the bolts inserted through slots in the frame so that by moving the block 69 up and down its contact, with the rollers 68 may 'be accurately adjusted to provide a good bearing surface.

The shaft 66 reciprocates in bearings 12 and 13 and is attached at its lower end to the plunger I; of the solenoid B. Attached to the shaft 66 is a lug I4 which engages the roller 15 on the arm 16 of a switch S3 which is mounted in the frame 24. With the parts in the position shown in Fig. 1, the circuit through this switch is closed and this circuit will be opened by upward movement of the solenoid plunger b and lug 14, the switch S3 having an internal spring tending to rotate the arm 16 counterclockwise from the position shown.

From the foregoing description it will be seen thatwhen solenoid A is energized its plunger 0 will rise,' carrying with it the die 38 and the clincher 48. The bracket 44 which is attached to the die will rise with it and in doing so a pin 11 carried in the lower offset portion of the bracket will contact the roller 18 attached to the arm 19 of the switch S-2 which is mounted in The circuit through switch S2 is this circuit, which controls the flow of current to solenoid B. Switch S2 contains a spring tending to return its arm '|.8to the position shown in the drawings.

When solenoid B is energized, its plunger b is raised carrying with it bracket 65 attached to shaft 66, thus moving toward one another the pivots 6| and 64 of the to gle-joint. This moves the roller 58 toward the clincher 48, exerting a powerful pressure against the clincher and moving it across the face of the die 38 into the position shown in Fig. 4 to bend down one side of the clip, as shown on an enlarged scale in Fig. 14.

From the successive views shown in Figs. 2. 3, 4 and 5 it will be seen that the die in its upward movement first shears oil a blank 39 from the strip 29, driving it against the coils of the Springs 42. The face of the die is so shaped that it bends the ends of the blank upwardly into a U-shape, forming a pair of upstanding wings as shown in Fig. 3. Upon movement of the parts to the position shown in Fig. 4 one of these wings is bent down upon thecoils by the nose 52 of the clincher 48. The electrical circuit is such thatas soon as this has been accomplished the solenoid B is deenergized, allowing the plunger b to drop. This retracts the toggle-joint and the clincher 40 moves away from the die under the 60. This clincher is bifurcated at its upper end and carries a nose piece held in place by pins 82. Clincher 4| is moved across the face of the die in the same manner as. in the clincher 40, by means of a toggle-joint having a roller 84 at its middle pivot which bears against a sloping face 85 on the clincher and operates in precisely the same manner as the other toggle-joint, obtaining its motive power from'the plunger 0 of solenoid C. The movement of these parts may be seen from a comparison of Fig. 1 with Fig. 5.

The nose pieces 52 and 8| [of the clinchers 40 and 4| respectively are made removable so that they may be replaced when worn and so that nose pieces of varying shapes may be inserted in the machine to produce clips of different types or sizes. Referring to Fig. 14, it may be desirable, for example, to use in the clincher 40 a. nose piece provided with a longitudinal ridge adapted to indent the clip as shown at 90 for the purpose of fixing the clip onthe wires in such manner that it will not slip. Such an indentation also tends to. strengthen the clip. Or a nose piece may be used which will bend the end of the clip down slightly around a wireas shown at 9| in Fig. 15. Other variations of an advantageous nature will readily occur to those skilled in the art.

Automatic strip feed Referring to Figs. 1, 7, 10 and 11, the strip 29 is automatically fed into the guide 36 at the proper time and in a measured amount by the mechanism here described.

After the strip passes through the guide rollers held in the bracket 32, it passes between the feed rollers 34 and 35. Referring to Fig. 7, the upper feed roller 35 is mounted on an axle I00 which is pressed downwardly by a-yoke IOI attached on either side to the cylindrical heads I62 of threaded studs I04. Heads I02 are mounted in a slot I05 in the table top 20. Each stud I04 passes through a boss I06 welded to the table top and having a hole the same size as the head and providing a bearing holding it in place. Each stud is provided with a pair of washers I08 and I09 between which is a coil spring IIO tensioned by nuts I I I. It will be seen that this structure resiliently presses the roller 35 against the roller 34.

The larger feed roller 34 is fixed on a shaft II2 which rotates in bearings attached to the brackets H4 and H5 (Fig. 10) which are attached to the frame. Also fixed on this shaft are the gears II6 and III which difier in size and arerides in a. collar I22 forming a part of the gear cluster. The yoke is attached to the end of a slider I24 which has a rack gear I25 driven by a a pinion I26 on the end of the shaft I21. The slider I24 is supported by a roller I28 positioned underneath the pinion I26. The shaft I21 extends beyond the frame 2| to the front of the table where it is attached to the gear shift lever 3|. By turning lever '3Ifthe gear cluster comprising the gears H3 and II 9 can be shifted into engagementwith either of the gears H6 or 1.

Referring to Fig. 9, when the lever 3| is in a vertical position the sets of gears just mentioned will be wholly disengaged so that shaft II 2 may be rotated without rotating the gears connected with the motor M. The lever 3| may be held in this neutral position by means of a pivoted catch I3I which may be held in either the raised or lowered position by the spring I32 attached to itandtotheframe 2|.

Keyed on the shaft carrying the. gears Ill and 3 (Figs. 10 and 11) is the large gear I34 which meshes with the small gear I35 on the shaft of the motor M. Spaced at regular intervals on the right-hand side of gear I34 are protruding amount of strip fed by the feed rollers 34 and 35.

It will be seen-that by shifting from the ar pair III-IIS to the pair II6II8 the linear travel of the feed roller 34 will be reduced and the amount of strip fed will be less.

The manner in which the amount of strip fed by this mechanism is automatically controlledand delivered at the proper time will be shown in the course of describing the electrical circuit.

Manual strip feed For the purpose of initially introducing the strip into the machine when it is first started or when a newv coil of strip is inserted, it is advantageous to have means for manually driving the feeding mechanism independent. of the motor drive. Before operating the manual feed the gear shift lever 3| is placed in'neutral'position and the dog clutch I40 is engagedby releasing the catch I 4| from engagement with frame 2|, turning it clockwise until it' drops through the notch I42 cut in the frame. Under the influence of the spring. I44 surrounding the shaft I45, the two parts of the clutch will be positively engaged through longitudinal motion of the shaft I46. The'shafts I45 and I46 are connected by a coupling I41 and may rotate together inasmuch as the catch MI is free to rotate in the space inside the frame 2| when the clutch I40 is engaged.

Fixed on the shaft I46is a gear I50 which meshes with the teeth on the gear I5I connected to the crank 30 by the coupling I48 and shaft I52. The gear I5I has some of its teeth removed, as shown at I53, those remaining being sufficient to rotate the shaft I46 through the gear I50 to deliver a predetermined amount of strip material into the machine when the crank 30 is given one complete turn. This amount is preferably slightly less than the distance between the point of contact of the feed rollers 34 and 35 and the left-hand wall of the guide 36, as shown in Fig. l.

The initial introduction of the strip 29 is accomplished by raising the upper feedroller 35 by means of the fork I60 (Fig. '7) which is fixed on shaft I6I. Also fixed on this shaft is a lever I62 (Fig. 8) extending beneath the table and secured in a bracket I63 bya pin I64. By removing this pin, depressing the lever I62 into the position shown in dotted lines in Fig. 8 and re-inserting.

the pin in the hole I65, the fork I60 will lift up on the studs I04 and relieve the tension between the two feed rollers, A measured amount of strip may then be introduced between them and the fork I60 released. Since the amount of strip which will be propelled by one turn of the crank 30 is known, it is a simple matter to introduce the correct amount of strip between the feed rollers for threading up a machine so that one turn of crank 30 will bring the end of the strip 29 across the face of die 33.

When this operation has been finished, the catch MI is withdrawn and turned counterclockwise into engagement with the frame 2!, thus disengaging the dog clutch I40, and the gear shift lever 3| is shifted to the right or left to give the desired gear ratio according to the size of clip to be made. The machine is then ready to operate automatically as hereinafter described.

Electrical circuit The functions of the electrical circuit are, first, to bring about in rapid succession and properly timed relationship the three clip forming operations, namely, (1) reciprocation of the die and first clincher, (2) movement of the first clincher across the face of the die and (3) movement of the second clincher across the face of the die. All three of these operations can be performed in one second, or less. Secondly, the circuit functions to control the motor which operates the strip feeding mechanism in properly timed relation to the clip forming mechanism.

Referring to Fig. 13, the circuit will be seen to comprise the switches SI, 8-2, 8-3 and S4, the solenoids A, B and C, and the motor M, previously mentioned in describing the mechanical apparatus. Additionally there are two relays and a rectifier for one of the relays. The entire circuit operates on alternating current.

The condition of the circuit shown in the drawings corresponds to the positions of the movin parts shown in Figs. 1 and 10. With the foot-' switch SI in its released position, relay RI is connected to the lines LI and L2 through the rectifier, switch SI and wires 20l, 202. Relay RI is of the adjustable magnetic time delay dropout type, operating. on direct current supplied by a copper oxide full-wave rectifier. When energized it immediately closes contacts 204 and 205 and when deenergized it opens these contacts and closes contacts 204 and 206 after a; delay determined by its adjustment.

After inserting the objects to be clipped together in the machine, the operator steps onthe footswitch Sl, opening the circuit through contacts 200 and 200 and closing the circuit through contacts H0 and 2I I. This immediately energizes solenoid A through wires M2 and 2I3, connecting it directly to the line,

As plunger a of solenoid A rises it closes switch s-z and connects solenoid B to the line through wires H5, H6, 2H, 2I0, contacts 204 and 205 of relay R-I and wire 2I9. Relay R-I is set to remain in the position shown for lon enough to energize solenoid B and raise its plunger 1) to do its work in moving the first clincher 40 across the face of the die, after which it automatically opens the circuit including contacts 204 and 205, thus deenergizing solenoid B although switch S2 remains closed.

While solenoid B is energized, its plunger 11 releases and opens the normally closed switch S3 controlling the circuit to solenoid C, which opcrates the second clincher 4|, so that when relay RI releases contact 204 to close against contact 206, solenoid C will not be energized until after the plunger b of solenoid B has returned to normal. This assures having the first clincher free to move out of the way before the second clincher is operated. Even if spring 49 does not retract the first clincher, because it sticks on the clip, for example, it will be pushed out of the way by the second clincher. After relay RI is released and switch S-3 has closed, therefore, solenoid C is energized by connection to the line through :vires 2I8, contacts 204 and 205, 220, MI, 222 and The foregoing operations complete the three clip-forming operations described above and we turn now to the motor circuit which is completed, upon release of the footswitch SI, and after the return of solenoids A, B and C to their deenerized normal positions. Solenoid B, of course, is at that time already deenergized by the opening of contacts 204 and 205 upon the release of relay RI.= Solenoid A is deenergized by therelease of the footswitch SI, opening contacts 2 l0 and 2| I. Closing of contacts 208 and 209 by the release of footswitch SI energizes relay R--I and immediately opens the circuit to solenoid C at the contacts 204 and 206.

As soon as contacts 204 and 205 of relay RI close, the motor M starts, current passing through wires 2I-9, 2I0, 225, switch 223 of relay R-2 and wire 221, at which time switch 226 is closed.

The closing of switch 226, which is a shunt for the off-pin position of'switch S4, previously had been accomplished as follows: The snapswitch S4 was in the position shown in Fig. 13 with its roller I30 engaging one of the pins I36 on gear I34, as shown in Fig. 10. This connected one side of relay R-2 with line L2 through wire 235. When relay R-I released, closing contacts 204 and 206, it connected the other side of 204 and 205 and wire 220, thereby closing switch .225, and also closing switch 230 of relay R2 which is a holding switch establishing a shunt circuit around the contacts 204 and 200 of relay R-I thereby connecting relay R-2 directly with line LI through wire 23I.

As soon as motor M has turned the gear I34 a short distance, switch S4 snaps to the "of! pin" position which shifts the circuit connectin motor M with line L2 from the switch 226 of relay R-2 to the snap-switch S4 through wire 234, simultaneously deenergizing relay R2 by breaking its connection with line L2 through wire 235. As soon as switch S4 is engaged by another pin I33 it snaps to the on pin position and stops the motor since' switch 228 in relay R-2 is then open. As soon as this happ ns the components of the circuit have all returned to the positions shown in Fig. 13 and are in condition to repeat the cycle of operations as soon as the footswitch SI is again depressed, held until the clinching operations have occurred, and then released. i

It will be obvious from the foregoing descriptio that the cutting of the ribbon and the clinchin operations take place while the footswitch S-I is held depressed; and that the feeding of the ribbon takes place, following the clinching operations, when the footswitch SI isreleased and rises.

The motor M found suitable for use in this embodiment is a self-starting synchronou inand bend it over said objects, and spring means I tending to hold said clinchers in their non-clinchduction motorgeared to deliver about 75 R. P. M. at the driving shaft.

Summary From the foregoing detailed description of the present preferred embodiment of the invention it will be seen that there ha been provided a high-speed, automatically operated machine for making and applying clips to objects to be secured together. As shown, machine can make such clips directly from continuous strip automatically fed into the machine in measured amounts, which amounts may be varied for the purpose of making clips of different sizes. It is apparent, however, that the clip forming and applying means could operate equally well without change if used with means for supplying precut blanks to the die instead of continuous strip. It might likewise be operatedby other means than solenoids as a source of motive power, means within the contemplation of the invention including either mechanical or hydraulic apparatus for reciprocating the parts shown herein as operated by the solenoids. It is also to be understood that the invention is not limited to applying positions; two toggle-joints respectively. cooperating at its knee with one of said clinchers to move the latter into clinching osition against the influence of said spring means, each of said toggle-joints having its upper end pivotally attached to a fixed point, two reciprocating members respectively attached to the lower end of one of said toggle-joints, and means for causing sequential movement of said three reciprocating members.
