THOMAS ARCHIBALD AITON, OF NEV YORK, N. Y.

WIRE-CORE MACHINE.

SPECIFICATION forming part of Letters Patent No. 742,551, dated October 2'7, 1903.

Application iiled May 4, 1903. Serial No. 155,538. (No model To @ZZ whom it may concern:

Be it known that I, THOMAS ARCHIBALD AITON, a citizen of the United States, residing at New York city, in the county of New York and State of New York, havein vented certain new and useful Improvements in Wire-,Core Machines, of which the following is a full, clear, and exact specification.

This invention relatesv to Wirecore machines, and has for its objects to provide a machine which shall be adapted to wrap two or more telephone or other wires with strips of insulating material and to twist such wrapped strands together to form a core.

Heretofore it has been customary to form telephone pairs or cores by separate operations, the Wires being first wrapped in one machine and then twisted or cored in another machine. Besides the increased time necessary where two machines are used more operatives are necessary to handle the product in the intermediate stages.

In o rder to carry out the objects of my invention, I have devised a machine havingr one or more heads in which aplurality of wires may be simultaneously wrapped and then twisted to form a core. In practice the machine comprises a plurality of independently-operated heads each of which forms a core. It is essentialthat the heads be independently operated, so that if an accident happens to one head the other will not be affected. Each head comprises a rotatable frame carrying two or more reels of bare wire and one or more idlers for covering each wire. The wrapped wires are twisted together by the rotation of the frame with respect to a lay-plate fixed on the strncture of the machine. The core is pulled `through the lay-plate and wound on a reel by suitable mechanism which may be driven from the main shaft. As the frame carrying the wire rotates each wire rotates with it, and consequently is itself twisted once for each rotation of the frame. This result is objectionable, because it varies the electrical propertics of the wire, and to overcome this I have provided a compensating mechanism which revolves each reel of wire reversely to the rotation of the frame. This overcomes the possibility of any torsion in the individual strands and is important in machines of this type.

The invention will be more particularly described in connection with the accompanying drawings, in which- Figure 1 is a front view showing one head complete and a portion of another head. Fig. 2 is an end view. Fig. 3 is a sectional'view showingthe driving mechanism for one frame. Fig. 4 is a detail View in section of the bear ing for one of the' fliers. Fig. 5 is a detail plan view of aball-retainer for the flier-bearing. Fig. 6 is a detail 0f the variable-speed gear for driving the draw-Off mechanism. Fig. 7 is a partial sectional view of a reelcarrier for the bare wire. Fig. S is a side view thereof. Fig. 9 is -a plan view of the topof the frame.

lis the main drivingshaft,carried in brackets 2, attached to the channels 3 of the framework of the machine.

4 and 5 are fast and loose pulleys for driving the shaft l.

The shaft 1 carries a series of clutch-disks 9, splined thereon, as many as there are heads, each of which engages lwith a disk 8, carried on a rotatable sleeve 6. The clutch-disk 9 is operated by a fork 11, which engages in the groove lO and is pivoted on a horizontal pivot The fork is operated to throw the clutch in. and out from'a treadle 14, which engages with a pin 82 on the rock-shaft 87. The rockshaft 87 carries a double-arm lever which engages with the arm 13 of the fork 11. The weight 15 normally holds the frontend of the treadle lifted and the clutch in engagement.

Whenjt is desired to stop the machine, the y front of the treadle is depressed, raising the weight and throwing the clutch out.

16 is a pivoted latch which automatically engages with the treadle to hold it down and the clutch out. The latch falls by gravity and istripped by the footvv of the operator when itis desired to startthe machine. The sleeve 6 carries a gear 7, which meshes with a gear 17 on a shaft 18, which carries a gear 19, meshing with a gear 2O on a shaft 2l,which carries a gear 22 and meshing with al gear 23 on the end of the shaft 24. The shaft 24 eX- tends through a support comprising a step 25' and a tube 25, which is carried on the said step. The step 25l carries the dead-gear 27 and a pipe 25", which latter has a collar 25, carrying the gear 28. The gears 27 and IOO 28 mesh with the fixed gears 29 and 55 to drive the fliers 44 and 39a. The fliers 39 are rotated oppositely to the fliers 44 by means of the intermediate pinion 55, meshing with the pinion 30.

I will now describe the construction of the rotatable frame which wraps and twists the wires to form a core. The frame comprises arms 3l, attached to the shaft 24, and the arins 32, connected with arms 31 by short rods 33. The arms 32 are connected to the tube 25, as shown in Fig. 3, and carry brackets 49, in which the rotatable guide-tubes 43 are carried. The guide-tubes 43 are carried at their other ends in arms 35, which are also connected to tube 25 similarly to the arms 32. The arms are connected by short rods 37 with arms 36, freely mounted on the step 25a.

The arms 3l carry bearings in which are mounted the rotatable tubes 38, which are borne at their other ends in a rotatable head 50, carried in a bearing-ring 51, mounted on the frame of the machine. The wrapped wires lead from the tubes 38a to a die or layplate 70, which is carried by a die-holder 7l on studs 72, mounted on the ring 51. It will be seen that the head 50, the tube 38a and 43, the arms 3l 32 35 36, the tube 25, the rods 33 37, and the brackets 49 together form a rotatable frame upon which the fliers, the compensating mechanism, and the rolls of bare wire are mounted, all being driven by the shaft 24. The fliers 39a and 44 are of similar construction and a description of one will suftice for the others. The rotatable tubes 43 have a bearing in the brackets 49 and in the arms 35. A detail of the bearing in the arms 35 is shown in Fig. 4.

73 is a collar attached to the tube 43 by a set-screw 74. The collar 73 carries a hardened plate 46, and the arm 35 carries a similar plate 45, between which plates balls 75 are retained by a plate 47, having holes 48, each hole being adapted to retain a single ball. The holes are so disposed that no two balls will revolve in exactly the same circle. By this means the balls will not wear deep grooves in the

plates

46 and 45. On account of the'high speed of the fliers it is necessary that some kind of ball-bearing be adopted. The tube 43 is driven by the gear 29, which is made fast by a set-screw 75. The gear 29 meshes with the dead-gear 27. The fliers 39 are mounted in the same manner, but are rotated oppositely by the intermediate gear 55, between the gear 28 and the pinion 30.

68 represents adjustable tension devices for the fliers 44 and 39a. The fliers carry rolls of insulating material-as, for instance, paper. The reel-carriers 76 are attached to gears 40, which are rotatably carried on a tube 7 7, mounted in the arm 36. The gears 40 mesh with idlers 39, mounted on arms 36, which idlers 39 mesh with a dead-gear 38, attached to the step 25a. By this mechanism it will be seen that the reel-carriers 76 will be rotated reversely to the shaft 24 and that consequently the individual wires will not be twisted on themselves, as would be thecase without this compensating mechanism. The reels 42 are detachably mounted in the reelcarriers 76 and have a suitable adjustable tension device 69 thereon. The wire leads from the reel through the tube 77, the tubes 43, over the rollers 78, and through the tubes 38L to the die 70. The

tubes

38 and 43 are partially cut away, as at 84, in order to permit the wires to be wrapped. By this construction the uncutaway portion of the tube forms a support for the wire and enables it to be wrapped more closely and uniformly than where merely the tension of the wire is depended on to form a support.

When the wires have reached the die 70, they have been Wrapped with two layers of insulation and have been twisted together.

52 is a draw-olf wheel, which is driven by means of pulley 56 on sleeve 6,- the rope 55, pulley 57, gears 58, 59, 60, 61, 62, and 63. From the wheel 52 the core passes to a winding-reel 54, which is driven in any suitable manner and removed when full. The drawoff wheel 52 is mounted on asleeve 79, which has a bearing on the cross-bar 8O of the machine-frame. The sleeve 79 carries a pulley 64, which has a belt 82, driving a pulley 67 on a shaft 66, carried in a bracket 65. The shaft 66 carries a double thread 81.

68 is a traveler which is rcciprocated back and forth by the double thread 8l. The traveler carries a pivoted follower which is guided in the groove of the thread. lfVhen the follower reaches one end of the groove, it is turned slightly, so as to bend the point the other way, and moves the traveler in the reverse direction. The core leads from the pulley52 through the traveler 68 to the windingreel 54.

I do not desire to be limited to the exact construction shown, as modifications may be made without departing from the spirit of the invention.

Having thus described my invention, I declare that what I claim as new, and desire to secure by Letters Patent, is-
