TWISTING-MACHINE.

Specification of Letters Patent.

Patented Oct. 1, 1912.

Application filed November 27,1911. Serial No. 662,608:

To all whom it may concern:

Be it known that I, ISAAC I1. VVoLKoW, a citizen of the United States, residing at Louisville, in the county of Jefli'erson and State of Kentucky, have invented certain new and useful Improvements in Twistingldachines, 'of which the following is a specification.

The present invention is a machine for making the hair structure described in my Patent No. 1,004,130, dated September 26,

1911, said structure consisting of strands of braided twine or other cord which are twisted together, and between which twisted strands are placed and held tufts of hair', wool or cotton.

It is the object of the invention to provide a simple and eificient machine for the purpose stated, and to this end it consists m a novel construction and arrangement of parts to be hereinafter described and claimed.

In order that the invention may be better understood, reference is. had to the accompanying drawings in which- Figure 1 is a side elevation of the machine; Fig. 2 is an enlarged cross-section on the line 2-2 of Fig. 1; Fig. 3 is a plan View of the track hereinafter referred to; Fig. 4 is an enlarged plan view, partly broken away, of the drive gear; Fig. 5 is an end View of the drive gear, and Fig. 6 is a section on the line 6--6 of Fig. 4:.

Referring specifically to the drawings, 10 denotes a suitable base which supports the mechanism. At one end of the base are mounted bearings 11 and 12 which support the various shafts of the gearing tobe presently described.

In the bearing 11 is journaled a hollow, horizontal shaft 13 carrying at one of its ends a bobbin-frame 14. In this frame are journaled two spindles 15 extending parallel to the shaft 13 and carrying the bobbins or spools of cord 16. The spindles are rotatable in the same'direction through a gear 17 in mesh with gears 18 on the respective spindles. The gear 17 is fast on a shaft 19 passing loosely through the shaft 13. -The spindles carry arms 20 having spring tension devices 21 to which the cord passes from the spools. From the tension devices the cord extends to the outer end of the spindles and is threaded through an eye 22 therein.

At 23 is indicated a main drive shaft A spindles 15.

which receives motion from a suitable source of power which latter need not here be illustrated as it forms no part of the present invention. On this shaft is fast a pinion 24 which is in mesh with a spur gear 25 loosely mounted on a hollow shaft 26 supported at its ends in the bearings 11 and 12. In the hub 27 of the gear 25'is a cavity 28 having in one of its end walls a key-way or slot 29. In the bore of the shaft 26 is mounted, to slide lengthwise therein, a stem 30 carrying a key 31 which extends sidewise throu h a longitudinal slot 32in the side of said s aft and enters the cavity 28. 'On the shaft 26 is also loosely mounted a spurgear .33 having in its hub '34 a key-Way 35 which is opposite and adjacent to the key-way 29. When the stem 30 is actuated to insert the key 31 into the key-Way 29, the motion of the gear 25 is transmitted to the sleeve 26, and when the key is inserted into the key-Way 35 also, the motion of the sleeve is transmitted to the gear 33. A suitable operating lever 36 is provided for actuating the stem 30 to engage the key with the key-ways as herein described and for disengaging the same. The width of the key is such that it may seat in both key-ways at. the same time, and the length of the slot 32 is such as to permit the key to be moved a sufficient distance to cometo this positiop.

On the shaft 26 is fast a pinlon 37 which is in mesh with a spur gear 38 which latter, in turn, is in mesh with a pinion 39 fast on the shaft 19, whereby the motion of the shaft 26 is transmitted to said shaft 19, and through the gears 17 and 18 to the The gear 38 is supported by the bearing 12.

The gear 33 is in mesh with a pinion 40, which latter is in mesh with a s ur gear 41 fast on the shaft 13. The pinion is supported by the bearing 11. This gearing transmits the motion of the shaft 26 to the also have'an orbital motion in the opposite direction, in view of which the cords are individually twisted in one direction while theyare twisting on themselves in the other lid fit?

direction. The gear ratio is such that the spindles rotate faster than the bobbinframe, I

The tufts of hair, wool or cotton are placed at suitable intervals between the twisted cords which produces the structure described in my patent hereinbefore referred to. The tufts may be fed between the; cords by hand; or an automatic feeding device may be provided.

A traveling carrier is provided whereby the finished article is carried forward away from the machine, and the cords are unwound from the bobbins. This carrier is constructed and arranged as follows: On the base 10 are supports 42 which carry sprocket wheels 43. Four of these sprocket wheels are provided and they are so arranged that the endless chain 44 which connects the same travels in a substantially rectangular path, the upper run of the chain being horizontal, and the chain traveling in a direction so that said upper run travels forward, or away from the twisting mechanism. On the shaft of one of the sprocket wheels is a worm gear 45 which is in mesh with a worm 46 on a shaft 47 on which is fast a large spur gear 48 which latter is in mesh with a pinion 49 on the shaft 13. It will therefore be evident that the gear of the twisting mechanism, through the worm gearing herein described, also drives the carrier, the worm gearing transmitting motion to the sprocket wheel in a direction to drive the chain in the proper direction.

The chain 44 carries grippers which are constructed as follows: To a block'50 are pivoted, as indicated at "51, two opposed jaws 52 which are held 0 en by a spring 53. The block is connecte to the chain so as to travel with it. Above the upper run of the chain is mounted a track comprising two spaced parallel bars 54 extending arallel to the chain and having flared en 55. The bars are so located that the grippers enter therebetween, and the space between said bars is such that they close the jaws when the latter come in contact therewith. On the outer surface of the jaws are antifriction'rollers 56 which-roll along the inner surface of the bars. The jaws 52 close when they enter the contracted space between the bars 54, and upon leaving the same they are opened by the spring 53. A suficient number of grippers are provided so that the finished article may be gripped at two points as clearl shown in Fig. 1. The shaft 47 is provided with a clutch 5?, an to the shaft of one of the sprocket wheels 48 is fitted a crank handle 58.

The machine operates as follows: The two cords are threaded through the tension devices 21 and the eye 22 of the spindles 15, and their ends are tied together. The cords are then pulled out until the lmot is above the carrier, and held there while the shaft 47 is disconnected from the drive gear by operating the clutch 57. The crank handle 58 is-now operated to position one of the grippers so that it may be engaged with the knotted end of the cords. The clutch 57 is now operated to connect the shaft 47 to the drive gear. The motor or other source of power being started, the stem 30 is pulled rearward until the key 31 enters the keyway 29, whereupon the spindles 15 are set in motion to give the individual twist to the cords. After a proper twist has been given the cords, the stem 30 is pulled still further until the key 31 enters the key-Way 35 also, whereupon the bobbin-frame 14 is also putin motion to twist the cords upon themselves. The, tufts of hair or other material are now placed between the cords as they are twisting on themselves, and the finished article is carried away by the traveling grippers as fast as it is formed, without any attention from the operator. At the forward end of the track the gripper jaws open and release the article which is at the same in stant picked up by a gripper entering the track at the rear. The drive gear of the grippers will be so designed that the grippers are carried forward at the proper rate of speed.

The machine can be run at any speed desired, and by means of the lever 36 is always under control of the operator.. The frame of the machine may also be widened and as many more spindles provided as are necgssary to produce any kind of twisted cor It will, of course, be understood that the machine as illustrated can be varied in construction within considerable limits, without departure from the spirit of the invention.
