MACHINE FOR APPLYING QO V ERINGS TO WIRE.

Specification of Letters Patent.

Patented July 3, i906.

Application filed January 20,1904. Renewed December 22, 1905. Serial No. 292,968.

To all whom/it may concern:

Be it known that I, JoHN ALLEN HEANY,-& citizen of the United States, residing at York, in the county of York and State of Pennsyl- Vania, have invented certain new and useful" Improvements in Machines for Applying Coverings to Wire, of which the following is a specification.

My invention has relation to a machine adapted to apply to a wire a covering of preferably insulating material, and in such connection it relates more particularly to mechanism of such a machine whereby the wire may be unwound from a-reel, properly fed through the machine while the wire is rotating, and then wound upon a second reel after the covering is applied.

In United States Letters Patent N 0. 740,131, granted to me under date of September 29, 1903, there is described and'claimed a method of producing insulated electric conductors, and among the stepsset forth as part of the method are those which prescribe that the wire must travel and must rotate while traveling through certain baths and during the application of asbestos fiber to the wire and the compacting of the fiber upon the wire. In the present application a preferred form of machine is illustrated designed to carry out the steps of feedingthe wire and rotating the same during the feeding operation.

The nature and S e of my present invention will be more full yunderstood from the following description, taken in connection with the accompanying drawings, forming part hereof, in which' 1 Figure 1 is a side elevational view of 'a machine embodying main features of my invention, certain parts of the machine being broken away. Fig. 2 is a to or plan view thereof. Fig. 3 is an enlarge detail view of the mechanism for unwinding, feeding, and rotatmg the wire, certain parts being illustitrated in section. Fig. 4 is an enlarged end elevational-viewof the friction-sleeve upon the arborsupporting the reel. Fig; 5 is a view similar to Fig. 3, but illustratin the mechanism for up the covere wire. Fig.

' 6 is an enlarged cross-sectional view on the line 6 6 of Fig. 3. Fig. 7 is a view similar to Fi 6, the section being taken on the line 7 7 of ig. 3. Fig. 8 is a detail side elevational view, still further enlarged, of the mechanism for laying the covered wire upon the reel. Fig. 9 is an end elevational view of Fig. 8, and Figs. 10, 11, 12, and 13 are enlarged detail views illustrating the construction of the reel upon which the covered wire is wound.

Referring to the drawings, a represents the framework of the machine, supporting at one end the unwinding mechanism A and at the other end the winding mechanism B. The frame a also supports intermediate of its ends certain mechanisms D,'E, F, G, and H for respectively covering the wire with glue, asbestoe, and a fireproof coating and for compacting and drying the covering on the wire prior to winding it up in the winding mechanism B. These mechanisms D, E, F, G, and H form the subject-matter of companion applications for patents, and a detailed dee, upon which the uncovered wire e is wound. I

The preferred means of detachably securing the reel e to the arbor a. is as follows: Upon the arbor a, is secured a conical piece e and on the screw-threaded end of the arbor is adapted to be advanced a conical thumb-nut a The reel e is clamped between the nut e and piece e when the nut is advanced upon the spindle, and by removing the nut e the reel e may be readlly slipped off of the arbor a. The arbor a is normally held from turning by the following preferred means: U on the outer end of the arbor a? is secured a ctio'n-disk e having a grooved periphery surrounded by a split band e The band at its lower end is bolted or otherwise secured to the bearing a, and the two ends of the band 0 are connected by an adjustable bolt 8, by turning which the band may more orless tightly engage the disk e. The reel e being clamped to the arbor a and the arbor a being normally, held from rotating, it follows that thereel cremains stationary under ordinary circumstances during the unwinding operation.- Secured to the sleergea which rotateswith the drivingpulley a, is a frame f, having on one of its arms a roller f over whi h the-wiree passes as it leaves the reel 6. ThisfIamef and roller f rotate or revolve around thereel-e to mwind the wire. therefrom. If the speed of revolution of the frame f is too greatto permit (if the proper take-off of wire from the reel e, the pull upon the-reel 2 becomes gge'a-t enough to overcome the friction-of" the and-e u'ponthe disk e", and hence the reel c, arbor a and disk e are I permitted to tm'n sufficiently to *relieve the tension on the'wire. at. The framef termi--- nates at its free end in two arms f and f preferably arranged as illustrated in Fig. 3 and in detail-in Figs. 6 and7. Referring to these figures, it will'be found that the arms f 2 and f are oppositely arranged tofoi'ma box sur rounding a tubularpiece g, through which the wire is topass, and the box-shaped ends of the arms f are inclosed by a tubular stationaryibear'ingy fixed to a standard a of the machine in a suitable manner. Each arm f f is provided with a g ear-Wheel g respectively; teeth on the periphery of which wheels-1 are-slightly inclined. .The gear-wheels g -gieach carry a groovedr'oller g 9 between t econtiguous'peripheris'of which the wire 0' Ifed'when the gear-wheels g g me. turned a e grooves of-the rollers g g are-arranged'at diametrically opposite I sides of the rotationof the frame and not only revoiveferound said axis, but also rotate .in" pIa11-e.;pas in through said axis.

To turn the gear-wheels 9 and y the rotary inotion of the f and f 3 is utilized by gage. acani ribg",

causing. the -teeth pf. the gear-wheels to en- I projecting from the face of the stationary tu ularbearing 9. As the framefre'vglvesthe rollers gf and g are positively to rotate the .wire and to feed the same thr'dugh" theimachine. as itais wound fronifthe reelgze by the'frame f. From such a" construction and. arrangement of parts it is nianifesti that the feeding 'ofthe wire e is dependent upon'the'spe'ed at which.

it is unwoundfrointhe reel e, and hence that buckling of thewire e'- is prevented. l The mechanism Bior up the wire after it has been covered and coated during its passage through the machine is substantiall the same as: that of the mec anismA; as a comparison of Fig. 5 with Fig. 3 will readily show, There are some ad-'. ditional elements necessaryghoweven in the winding'mechanisrn, dueto the fact that the .wire by-rea son of its coating and covering has increased in diameter,' and some 'pro vision must'be made for the covered wire smoothly upon its real e Again, some provision must'also be made to permit a slot of the frame f thus reciprocating the roller f is preferably constructed -and arranged as illustrated in the wire when inround'lipon the reel 0" tobe.

readily removed therefrom, and some changes in the structure and arrangement of the reel and its operating and supporting'parts are consequently necessary. "mechanism B a sleeve 0 driven by a pulley In the winding A frame f and the teeth 6 Oil the frame f is a roller f, over u on theframe f but is mounted upon a b ock f 3, arranged to slide back and forth in The mechanism for detail in Figs. 8 and 9. It consists of, a leverarm h in slotted engag cut at one end with the block f and pivote at its other end to the frame f Intermediate of'its ends the le ver-arm h is provided with a roller It, bearing upon-the periphery of a heart-shaped cam if.

The cam h is secured to the sh aft 71, of a gearwheel-hfl the shaft h having its bearings in theframe f Theteethof the gear-wheelh Aen'ga ewith a cam-rib 712', formed upon the perip' ,ery of one of the two disks comprising the faces of the reel e As the framef re- 'which the wire e" travels on its way to the reel e This roller f is not stationary volves about the reel e the gear-wheel h and cam h" are rotated to cause the leverarm h to reciprocate the blockf and roller f The cam h being heart-shaped, as illustrated, will throw the lever-arm h and block f toward the left in Fig. 8, while in the opposite direction the pull'of'the wire will keep the roll h in contact with the cam h" and effect the movementof the lever-arm h. and

roller f flis caused to reciprocate over the body of'the reel. e to be evenly laid thereon block f toward the right in sai'd figure. It \follows that the wire en, passing over the during the winding operation; The reel e movable from the body 0 of the reel; and the other, 24 is fixed to.a hub or boss e and isr'a-dially slotted. The hub 6 is carried by a-sleeve e ,-inclosed within the driving-sleeve bi, and is separated from an enlargement or collar b on said sleeve 1; by a washere The has two disks or.faces,-one of which, e is re sleeve e? is traversed by anarbor 6 which is provided with a nut 1), bearing against one member of a ball-bearing b the othermerii ber of said ball-bearing resting against the hub c to hold the hub e a ainst the frictionwasher e A'scr ew-nut 7 serves to force the nut- 6 toward or away from the hub efirso The body e preferably three in number, and normally surrounding the hub e. A clamping-screw 6 passing through a radial slot of the disk 6 serves to secure each section of the body to the front disk e When loosened, the screws e permit the sections to collapse. or decrease in diameter when the body 6 is removed from the hub e Thumb-screws c serve to detachably secure the front disk e to the hub e. at its back a' pin a, swiveled to the section, and when projecting radially from the section adapted to enter one of the radial slots of the disk e carried by the hub e. The pins e serve normally to confine the coil of wire on the body 6 and may be turned so as to traverse the body a diametrically after said body is removed from the hub e. This construction and arrangement of thereel e permits of the ready removal of the coil of wire e when a suiiicient length of Wire has been .Wound upon the reel; Thus upon unscrewing the thumb-screws e the front disk a, with the body e and coil of wire, can be drawn away from the hub e and back disk e Upon turning the pins 6 and collapsing the sections of the body e the coil of wire can now be withdrawn from the body away from the front disk e After withdrawal of the coil the reel e can be reassembled by a.

reverse operation of the parts. If the tension upon the wire 0 becomes too great during the winding'operation, it is relieved by a slip of the hub e on the friction-washer e Having thus described the nature and objects of my invention, what I claim as new, and desire to secure by Letters Patent, is
