claims. (c1. 242-156) The present invention relates generally to a, wire reel control, but more particularly to a novel and improved device for automatically stopping and controlling the speed of an unwinding reel of wire.

The present invention has particular adaptation for controlling the speed of unreeling wire or wire reel for a variety of purposes, but hasv especial application in connection with controlling the supply of wire to a machine for making or forming coil springs and the like type of machines.

In supplying or feeding wire to this or other types of machines, the speed of the wire fed thereto is usually uniform, but when the wire is unwound or Vdrawn from an uncontrolled revolving reel ofv wire, the momentum of the revolving reel of wirecauses it to exceed its normal speed requirements, resulting in the feeding of -an eX- cess amount of wire, which usually becomes H@tangled and therefore interrupts and delays the .efcient operation of the spring forming machine.

Then too, occasionally the spring forming or :spring coiling machines become jammed up and :automatically stops and unless the unvvinding :.reel of wire is simultaneously stoppedwith, the amachine, the reel will continue to'unwind the `wire with the result that a mass of tangled wire v is strewn about the place.

,It is `therefore the primary object of the present invention to Anot only overcome the difficulty hereinbefore pointed out, but to provide a simple and efficient control for the feeding of an unlreeling roll of wire and will also automatically vstop the rotation ofthe revolving reel simul- Fig. 3 is a cross sectional view taken on the lline 3-3 in Fig. l of the drawings showing di- Vagrammatically how the solenoid is connected V.through Ya wiring circuit to one of the control members of the spring forming machine; andv Fig. 4 is a fragmentary cross sectional view ktaken on the lines 4-4 in Fig. 1.

In illustrating one form which my invention .Amay assume in practice, I have shown the same as comprising a substantially circular pedestal or base member I0 which is adapted to rest on and be secured to the floor. The base member is provided with a vertically and upwardly ex- Y tending and centrally located sleeve portion II.

`Secured by means of a set screw I2 in the sleeve which is in axial alignment with the axis of the f'tubular standard I3. rigidlysupports therein a vertically extending shaft 'I9.`

This bore receives and `Journ`aled on the shaft I9 is a circular ,disc 2D. Secured to the disc 20 are four radially projecting arms 2| arranged at right angles with` respect to one another. Secured to the outer portion of each ofv these diametrally positioned arms 2I are reel supporting members,

taneously with the stopping of the machine to which the wire is fed.

A. still further object of the invention is to provide a novel and improved adjustable governor control for uniformly feeding wire from an unreeling roll of wire in which a tubular y standard forms the support for the automatic stop for positively stopping the rotation of the reel simultaneously with the stopping of the machine to which the wire is fed.

These and other objects are accomplished by 1; .providing a construction and an arrangement of vthe various partsrin the manner hereinafter del scribed and particularlyzpointed out in the ap- .pended claims.

: Fig'. 2 is an enlarged cross Vsectional view taken on the line 2-V2 in Fig.Y 1 of the drawings;

generally indicated by the reference character 22. These members 22 are preferably made of fflat steel bars of identical configuration and include yraised central and horizontally extending portions 23. Substantially vertically depending portions 24 which are equally spaced from the axial center of the shaft I9. The lower portions of these members 22 are bent in substantially right angles to the vertical portions as shown at .25 so as to form horizontally projecting portions 26.` r These portions 26 of the members 22 are welded to the adjacent radial arms 2l. The outer "ends of each 0f these members 22 are turned upwardly to form vertical supports, as shown at 21, for'an annularvor circular ring 28. The ring J28 is welded to the upper end of these supports jf'The construction thus far described forms th frevolving reel in which a roll or reel of wire, as

vshown in broken lines indicated by the reference character 30, may be supported. The wire from l roll may b'e drawn off by a single strand arms 44.

4vertically depending pins 55. v reciprocally mounted in oppositely disposed verti-V 3 as shown at 3l. Secured to the underside of the horizontal portion of each of the members 22 is a circular disc 32. Located in the axial center of the disc 32 is a circular or bearing recess 33 forming the journal connection between the upper end of the shaft and the revolving reel.

The mechanism for controlling the uniform feed of the unreeling wire includes a novel governor control which is provided with two types of adjustment so that the limit of the speed may be varied to meet the requirements of the machine to which the wire is being fed. `llhis novel governor control includes a collar 34 which embraces and is secured to the tubular standard I3 by means of a set screw 35. The collar 34 is provided with an annular flange 36 on the lower face of which is secured a leather braking washer 37. Slidably mountedon and journaled onthe tubular standard I3 is rotatable braking member 38 which has an annular flange 39` whose upper face is adapted to move into engagement with the leather washer 3l to limitthe speed of the revolving reel in the manner hereinafter disclosed. rIhis braking member has oppositely disposed spaced apart apertured ears-40 to which are pivotally mounted, as shown at 4I, oppositely disposed curved links 42. The upper ends of these links d2 are pivotally connected, as shown at 43, to oppositely disposed suspended governor These governor arms 44 lare provided with a series of spaced apart apertures'45 for adjusting the position of the upper ends of the links l2 to vary the limit of speed of the revolving reel. The governor arms 44 are each provided with the usual governor weights 45 which may be adjusted along the length of each of the arms 'and secured thereto by suitable set screws 4`i-to `furnish another means for varying the speed limit of bolts I From the above description it will be obvious f that as the revolving reel Areaches a predetermined speed or a speed in excess of thatY-set'by the adjustment of Vthe governor, the centrifugal force of the revolving reel will cause the governor arms fll, together with their respective weights 46 to swing outwardly upon their Vrespective pivots @i8 on the bracket Eccand thereby cause the upper face of the flange 330i the governor member 38 to engage the braking surface of the leather washer 3l' to restrict the speed and maintain the unreeling of the wire at a uniform predetermined speed.

n combination with my improved means :for maintaining a uniform speed of the revolving reel, I have employed common and associated parts to form a stopping mechanism to stop the reel simultaneously with the stopping of the machine with which my improved reel control is used. This novel means includes a disc or washer-like member 52 which is secured to the underside of the disc 12E) by means of screws 53.

Secured to the underside of the disc 52 is a leather or braking washer 54. Adapted to move into'en- The braking disc 55 is rigidly secured tothe upper ends or two oppositely disposed and These pins Y56 are cal bores 5l formed in the hub or housing mem- Cil ber I'I. The lower ends of the pins 56 project into an annular recess 58 formed in the lower half of the hub Il. Reciprocally mounted in the recess 58 of the hub I'I and adapted to engage the lower ends of each of the pins 56 is a plate or disc 59. The plate or disc 59 rests upon and is normally pressed upwardly by four uniformally spaced apart springs Eil. The springs 60 are seated in four uniformally spaced apart sockets 6! formed in the cap member I5, as clearly shown in Figs. l and 2 of the drawings. Secured to the axial center of the disc or plate 59 by means of a nut 52 is a rod 53. The rod 63 is reciprocally mounted within the tubular standard i3 and extends into central hollow portion of the base I0. The-.flower endfof the rod 63 has its lower end bifurcated as shown at 54 so as to straddle a lever 65. The bifurcated portion 54 of the rod 63 has aligned apertured ears 83 in which a pin 61 pivotally connects the lower end of the rod to the lever 55. The pin El extends through a horizontal slit 68 in the lever 65. The lever 65 is pivotally connected as shown at 69 to a bracket 'I0 .secured to and within the base by means of screws lI. The freel end of the lever S5 projects through a slotted-opening l2 formed in the base Y member IG and has its outer end twisted as shown at 'E3 to form a foot pedal. Secured to the base l0 -adjacent the slotted opening 12 is a bracket lll, which is secured to the base by meansof screws or bolts i5. The bracket 'I4 has vertically extending wall or at portion 'I6 formed integrally therewith. Pivoted to the wall- I6 as shown at 'I'I is a-latch member l. The lower end of the latch member 'E8 has a rectangular recess 'I9 for receiving and locking therein the leverv as clearly `shown in Figs. 1 and 3 of the drawings. The recess T9 in the member' 'I8 forms a laterally projecting linger 8U which normally engages the lower edge -of the vlever-55 when Vthe foot pedal 'i3 is depressed to actuate the latch I8 toits normally locked position. The latch member 'I8 is normally held in the locked position, or the position shown in Fig. 3 of the drawings, by a lever member El which is pivoted at 82 tolthe verticalfwall 75. One end of the lever 8I has a notch -formed therein to engage the'upper end of the latch '58. rhe lever is normallyactuated i in a direction to engage the latch 'i8 by a tension gagement with the braking washer 54 to inter- .rupt or stop the rotation of the reel, is a braking disc, 55.

springt@ which has one end thereof attached to a pinY carried by the lever 8l -and the other' end thereof attached to a pin 8B carried bythe wall'IS. -A laterally projecting lug 8l forms a stop for the lever 8l. The other end of the lever SI Vis pivotally connected as shown at 8l to a reciprocable member 8B of a conventional type of solenoid, generally indicated by the reference character 89.` The solenoid 39 is mounted in any convenient manner on the bracket lll. V'The'mechanism may be suitably housed by a sheet metal box, generally indicated by the reference character 90. The solenoid 89 is provided with the usual terminals QI and electric circuit wire connectionsQZ, the latter of whichmay be connected to a suitable switch or relay generally indicated by the reference character The switch in this instance may be vactuated by a lever'94 pivoted onl a suitable port 94' of the machine to which the wire is being fed. The lever 94 in this linstance may control the operation ofsany type of spring forming machine or the like, whichy is actuated to control the operation of the same. The lever 94, also may be automatically actuated, one for example, by an accumulation of springs which clog up the operation of thespring forming makthereforevbe seen that as the operation of the lspring forming machine is interrupted or stopped `This permits the four springs 69 to actuate the disc 59 upwardly, which in turn, through the pins,v

forces vthe braking plate 55 against the leather brake 54 of the reel and thereby brakes or stops the revolving reel.l

summarizing the advantages and function of operation of my novel and improved control for the unreeling or unwinding of wire from a revolving reel, it will be readily seen that I have provided a device which will not only feed the wire at a uniform speed, but will also provide adjustment to vary such speeds and to permit a stopping of the reel simultaneously with the stopping or interruption of the machine to which the wire is fed. During the normal operation of the reel, the foot lever 13 is depressed and locked in the position shown in Figs. l and 3 of the drawings. In this position, this lever holds the rod 63 downwardly by compressing the plate 59 against the compression springs 6l and thereby holds the braking or stop plate 55 away from the braking leather washer 54 so that the reel proper is free to revolve on the shaft I9. As the Wire yis unreeled within a predetermined speed, as determined by the adjustment of the governor control, the friction surface 39 of the collar 38 is held in close proximity to the braking disc 31 by the governor control and if the speed f the reel should be in excess of that set, the braking action will take place by reason of the centrifugal action of the governor to retard the speed in a manner similar to that of a conventional governor. However, if for any reason the machine to which the wire is being fed is accidentally interrupted or stopped, or for the reason that springs formed thereon accumulate in such a fashion as to actuate the control lever 94 carried by the machine, then and in that case the actuation of that lever 94 closes the circuit or switch 93 and thereby energizes the solenoid 89 which, in turn, through the connections hereinbefore described, releases the lever B5 and through it, the rods 63. The releasing of the rod 63 permits the pressure springs 6B to actuate the braking disc 55 against the braking washer 64 to simultaneously stop the revolving reel with the stopping of the associated machine to which the wire is fed.

In this connection it will also be noted that I have not only provided an automatic means for stopping the rotation of the reel and a governorstructure which is simple in construction. and

eilicient in operation.
