8 Claims.
This invention relates to the manufacture of electrical wiring and, more particularly to the assembly of wire with metal eyelets for making connection with a terminal. An object of the invention is to provide apparatus for forming a wire around the shank of an eyelet and for crimping the eyelet around the wire in one operation. To accomplish this object we provide tools which may be readily attached to a standard eyelet machine. These tools cooperate to provide a combination of means for removing an eyelet from the lower end of a chute leading from the magazine feed of the standard eyelet machine and for locating the removed eyelet upon an anvil preparatory to riveting, means for bending a bare wire around the anvil preparatory to receiving the eyelet and means for causing the eyelet to enter the loop of wire formed around the anvil and to cause the eyelet to be crimped around the wire, thereby permanently attaching the eyelet to a loop of bare wire at the end of an insulated conductor.
Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawings wherein a preferred embodiment of the present invention is clearly shown.
In the drawings:
Fig. 1 is a perspective view of a fragment of wire having an eyelet attached thereto by the present machine.
Fig. 2 is a perspective front elevation of a standard eyelet machine to which the tools of 1 the present invention have been attached.
Fig. 3 is a fragmentary view on an enlarged scale of the lower end of the chute looking in the direction of arrow 3.
Fig. 4 is a perspective view of the top portion of the anvil looking in the direction of the arrow 4.
Fig. 5 is a fragmentary longitudinal sectional view showing the tools of th present invention, the upper movable parts being shown in a position corresponding to that shown in Fig. 2.
Fig. 6 is a fragmentary sectional view of parts shown in Fig. 5, the upper tools having been lowered part way.
Fig. 7 is a view similar t Fig. 5, the upper tools having been lowered to the extreme lower limit.
Fig. 8 is a sectional view on line l--8 of Fig. 5.
Fig. 9 is a fragmentary sectional view on an enlarged scale of parts shown in Fig. "I.
Fig. 10 is a fragmentary view on the line Ill-l0 let machine is described in its entirety by numeral 20. This machine comprises a vertically reciprocating member 2| carrying at its lower end a sleeve 22 to which certain tools of the present invention may be attached. The member 2| is reciprocable or cam operated by shaft not shown which is driven from a fly-wheel 23 operated by an electric motor. The eyelets to be attached to the work by this machine are fed automatically from a hopper 24 and are caused to slide down a chute 25 comprising aligned side plates 25a and 25b, Fig. 3, supported by a frame 250 which serves as a top or cover plate for the chute. The frame 250 is pivotally supported at 26 and is caused automatically to swing toward the left from the position shown in Fig. 2 once during every cycle of the machine as will be explained in detail later. The lowermost eyelet E in the chute 25 is yieldingly retained in position by a finger 21 provided 'by an arm 28 pivoted at 29 and yieldingly urged into eyelet retaining position by a spring 30.
Referring to Fig. 5 the sleeve 22 extending from the slide 2| supports an eyelet riveting punch 3| having a central bore for receiving an eyelet pilot pin 32 the head of which is received by the central bore 33 of the sleeve 22. A set screw 3| a fastens the punch 3| to the sleeve 22. A spring 34 within the bore 33 yieldingly urges the pin 32 downwardly. The punch 3| supports a tubular, wirebending sleeve 35 the lower edge 36 of which is shaped somewhat after the fashion of a long lead screw thread. The wire bending sleeve 35 is attached to the punch 3| by a set screw 31 locked by a nut 31a, see Fig. 8.
Vertically below the concentrically disposed eyelet pin 32, eyelet rivet punch 3| and wire bending sleeve 35, there is a centrally disposed anvil 40 located concentrically with respect to a sleeve 4| supported by a block 42 which, as shown in Fig. 2, is carried by a bracket 43 which is adjustably supported by a plate 44 carried by the fram 45 of the eyelet machine 20.
The stem 50 of the anvil 4|! is fixed to the block 42 by set screws 5| located by nuts 52. The upper end of the anvil 40 is provided with a depression 53 for receiving the lower end of pin 32. Anvil 40 provides an annular groove 54 for forming the lower edge of the rivet E.
To use the device the operator places the bared .end of an insulated wire W in the position shown in Fig. 10 with the bared end extending across the right hand side of the annular groove 54 the end thereof being received by a stop Referring to the drawings, the standard eye- 55 member forming a part of the block 42. Then the machine is started into operation by depressing a manually actuated pedal, not shown. As the sleeve 22 descends from the position shown in Fig. 5, the pin 32 will pass thru the lowermost eyelet E in the chute 25; and, before the pin 32 engages the upper end of the anvil 40, the chute frame 250 will have been moved clockwise about its pivot 26 thereby retracting the chute from the eyelet E then on the pin 32.
, As the chute 25 moves away from this eyelet E,
the finger 21 is pulled open; and, after the eyelet E has been removed from the finger 21, it snaps back to receive the next eyelet in the chute. Finally the pin 32 engages the anvil Ill and locates the eyelet E upon it.
During further downward movement of the sleeve 22 the pin 32 remains stationary while the punch 3| and the wire bending sleeve 35 continue to move. The lower edge 36 of the wire bending sleve 35 engages the wire W and causes it to be formed into an annulus around the anvil. as indicated by the dot-and-dash line "in Fig. 10. During this operation the bending sleeve 35 is received in the annular space 55 between the anvil 40 and the sleeve 4|. Finally the punch 3|, which is provided at its lower end'with an annular groove 3 |a, engages the rivet E to cause it to be moved from the position shown in Fig. 6 downwardly along the anvil 40 and to berreceived by the annulus of wire surrounding the anvil. During this movement of the eyelet its tubular skirt is flared and is caused to follow the contour of the anvil down into the annular groove 54 and then upwardlyaround the annulus of wire represented by the dot-dash line circle I see Fig. 10. Finally the eyelet E is completely formed around. the annulus of wire as shown in Figs. 7 and 9. Fig.9 shows that the bottom edge portion E of the eyelet has been folded under that portion E which originally was the top or flange of the eyelet.
Referring to Fig. 2 it will be observed that the wire bending sleeve 35 is provided with a notch 35a which clears that portion of the wire W extending from the insulation and crossing the space 55 to the anvil 40. Therefore when the sleeve 35 descends to bend the bared wire into the annulus represented by the dot-and-dash circle 10, this annulus will not be severed from the straight portion of the wire.
The core of the wire may be made up of stranded fine wires. If 'the annulus of wire is too lon for the eyelet, some of the core strands may be cut off by the cooperation of the anvil l0 and the sleeve 35. Small bits of wire can descend thru the space 55 and find their way out of the block 42 thru the side passages 58 provided by the block 40.
The machine is operable to form a loop at the end of a solid wire whether or not an eyelet is attached thereto.
