which the following is a specification.

ur invention relates to machines for winding Wire into coils, and more specifically to machines for Winding comparatively fine wire into close coils. Our invention is particularly adapted for making metal filaments of the coil type for use in incandescent lamps. These filaments are much used in cases where a concentrated light source is desired. It is necessary that the length order that the resistance may be accurately fixed. It is desirable, also, that filaments of this kind be formed rapidly and in a manner calling for a mlnimum of manual attention. For this reason it isdesirable to forma series of filaments from a continuous Wire and to space the filaments apart. This necessitates a very accurate control'of the winding mechanism. Moreover, it is desirable to have each filament composed of legs portions are engaged by the filament supports in the lamp. This necessitates that the control for the Winding mechanism be In the drawing,

The ob ect of our invention is to provide an automatic machine for accomplishing the purposes set forth in a highly accurate and e cient manner.

According to our invention, the filament Wire is fed through a measuring device, the speed of Which corresponds accurately to sible, by using a traveling mandrel, to cause a continuous operation of the machine and to form a continuous filament of any desired length Without stopping the machine, Iprefor to use such a mandrel and to rotate the 55 filament Wire thereup n, although it is ob- 'es of gears 23,

attached theret pinion 33 and ir of rolls 11!;

34, which frictionally engage the mandrel wire. It is obvious, however, that any suitable device may be substituted for these friction rolls provided the speed thereof corresponds to that of the disk 31.

The filament wire may be carried by a suitable holder, such as spool 35, mounted on the head 16. The filament wire 36 extends from the said spool across the stationary guide 37, the part 37 of which engaging the filament wire may be of felt v1 other soft substance which will not wear the wire. The wire then extends around a grooved guide roll 38 and a measuring disk 39. The said disk is peripherally grooved to receive the wire and is removably carried by the stud 40 supported in anti-friction bearings in the head 16. Various sizes of such disks may be used depending upon the size of the wire and the pitch of the coils desired. The stud 40 carries a pinion 41 which engages with the peripherally toothed disk 42, which is rotatably supported in the head 16. Carried by or integral with the disk 42 is a disk r or disks, the periphery of which is formed into the

cams

43 and 44, as shown in Figs. 3 and 4. Bearing against the upper cam 43 is one end 45 of a pawl 46 pivoted at 47 to the head 16. The other end is attached by spring 48 to the said head. Below the pawl 46 is a pawl 49 also pivoted at 47 and having one end 50 engaging the cam 44. The other end of the pawl 49 carries the double contact 51 which is adapted to engage either of the

stationary contacts

52, 53. As shown in Figs. 3 and 4, a leaf spring 54 is attached to pawl 49 and to the pawl 46. The arrangement is such that when the end 45 of pawl 46 falls into an indentation in cam 43, the end 50 of pawl 49 is simultaneously ejected from an indentation in cam 44, and, as the end 45 is forced gradually out of its indentation, the spring pressure upon the end 50 gradually increases until, at the instant end 45 leaves the indentation, end 50 is forced into its indentation. It will be apparent, therefore, that the pawl 49 is always under pressure from the spring 54 and this causes it to operate instantly and to cause instantaneous shifting of the movable confact 51.

The

contacts

52, 53 are in circuit respectively with the

solenoids

52, 53. The latter are mounted below the machine and control the armature 54 carried at the end of a lever arm 55 fulcrumed on the bed of the machine at 56 and carrying at its other end the rod 57 slidably mounted in the sleeves 53, which may extend from the standards 15. The said rods are attached to a mechanism coi'nprising the brake 59 and the movable clutch member 60. The stationary clutch member 61 is conical and so fashioned that its inner surface is engaged by the movable clutch member 66 and the brake 59.

It will be obvious that when the rods 57 are moved to the right the clutch will be thrown out and the brake brought into operation, while a movement to the left will cause the clutch to be thrown in and the brake to be thrown out. The movement of the pawl 49, caused by the cams before referred to, will cause the contact 51 to engage with the

contact

52 or 53, as the case may be, and thus cause the rotation of the head 16 to be stopped or started instantaneously.

The electrical connections are shown diagrammatically in Fig. 6. Energy is obtained from a suitable source, such as motorgenerator set 62. One terminal thereof is connected in multiple with the

coils

52, 53, which are connected respectively to metal straps 63, 64 engaging the

rings

65, 66 respectively. These rings are shown in Figs. 1 and 2 and are mounted on the shaft of the rotatable head 16. They are connected to the

contacts

52 and 53 respectively. The movable contact 51 is connected to ring 67 mounted with the other rings and engaged by a strap 68 connected to the other terminal of the generator.

It is preferred to heat the coiling end of the filament wire aml this is most conveniently accomplished electrically. As shown in Fig. 6, the energy is obtained from transformer 69, to out terminal of which is connected a strap 70 engaging ring 71 mounted with the other rings hereinbefore described. Ring 71 is connected to post 72 carrying the spring clamp 73 engaging and serving to hold the end of the filament wire against an insulating block 74. A metal block 75 engages the mandrel wire adjacent to the coiling end of the filament wire and this block is grounded. It will be apparent that the heating current will pass through a short length of the filament wire at the coiling end.

The operation of the above described )arts will be a) )arent. As soon as the machine is started the mandrel wire may be made to move at any desired speed to manipulate the various change speed mechanisms. The rotation of the head 16 will cause the filament wire to be unwound from the spool 35 causing a rotation of the disk 39, the end of the filament wire adjacent to the mandrel will be heated. The size of the disk 39 is so chosen that the proper length of wire will be unwound to correspond to the speed of the mandrel so as to obtain the proper length and, therefore, the proper amount of resistance of the filament. The rotation of the disk 3.) will cause the

cams

43 and 44 to rotate and thus to operate the movable contact 51, and thus to intermittently stop the machine and start it again. This causes plain spaces to be formed between the coils, and it will be obvious that this may occur as many times as desired,

live movement at predetermined the machine is entirely automatic, requiring a new spool of filament wire in place or attaclnng a new reel of mandrel wire and removing that upon which the filament has been formed.
