Combined Fiber Feeders and Mixers, of

' which the following is a specification.

My invention has reference to an improvement in textile machines and more particularly-to an improvement in a combmed fiber feeder and mixer, for uniformly mixing various kinds of fibrous material such as waste cotton with raw cotton, silk with linen, cotton with wool, or one kind of a fiber with a different fiber either in texture or incolor.

In the textile industries there is a certain percentage of waste.

drawing slive, spinners stick waste and other forms of waste. In the economical operation of cotton or yarn mills -it is essential that this waste cotton shall be utilized to the best advantage so as to eliminate this loss in waste. vThis waste which has to be rerun does not readily mix with the raw stock when fed into 'a hopper bale opener by hand in the usual way and these bale openers or feeding machines will pick out the waste or rerun stock more readil than the raw stock, thus the mixed stoc actually fed has at times a larger percentage of waste or rerun stock. In order to minimize this tendency the unskilled attendant is required to feed the waste or rerun stock into the machine in small quantities or a little at a time, which is a tedious and impractical operation, as the attendant cannot be depended on to feed by hand unvaringly the required amount of waste or rerun stock. As heretofore partially and inadequately accomplished this cotton waste was mixed with the raw cotton in a machine known as a'hopper bale opener, in the"following manner. The hopper bale opener operates to break up or disintegrate the bale cotton and the waste cotton is fed into the machine by hand, the operator, usually of the lowest grade help, throwing from time to time a small portion of the waste cotton into the machine on to the raw cotton. By this method and use of necessarily unskilled ton with the raw cotton,

In cotton mills this cotton waste is in the form of card slive,

hand labor, it is practically impossible to obtaln a uniform mixture of the waste cotas it is necessary to depend on the udgment of the operator as to when the waste cotton should be thrown into the machine also as to the amount of waste cotton that should be mixed with the raw cotton to give the best result. In prac tice it has been found that by the use of unskilled or any kind of hand labor for this purpose, an uneven mixture of the cotton waste and raw cotton is obtained and this uneven mixture can be traced through the various machines and processes to the finshed yarn, where it is found that the yarn is uneven in strength and texture caused by the uneven mixing by hand of the waste cotton with the raw cotton.

The object of my invention is to provide the textile industries with a machine adapted to mechanically mix a uniform and predetermined amount of' waste fiber with'raw fiber, to disintegrate the mixed fiber and feed the disintegrated mixed fiber to a bin,

lap-head or other textile machine, to which f it is applicable. I

1 My invention consists in the peculiar and novel construction and combination ofparts in a combined fiber feeder and mixer, said combined fiber feeder and mixer having details of construction as will be more fully set forth hereinafter and claimed.

Figure 1, represents a side view of my improved combined fiber feeder and mixer, showing the same connected to a lap-head, and Fig. 2. is a longitudinalsectional view through the fiber feeder and mixer and the lap-head.

In these views the lap-head is shown only to illustrate one form of a textile machine to which my improved combined fiber feeder and mixer is particularly adapted. As the lap-head has noconnection with my'invention a description of the same is unnecessar combined fiber eeder and mixer and 6' a lap-head, 7. 7. indicates the side frames of the combined fiber feeder and mixer which support the operative mechanism of them-a chine, 8 indicates an endless horizontal lower carrier apron which extends lengthi. wise of the machine just above the floor line;

n the drawin ,[5 indicates m im ro'eedr This apron 8 is supported on rolls 9. 9. journaled 1n bearings in the side frames. One of the rolls is driven to move the u per portion of the apron in the direction 0 the arrow at, as shown in Fig. 2. An endless spiked apron 10. is supported on rolls 11. 11., in a vertical position. These rolls 11. 11. are journaled in bearings in the side frames, the shaft 12. of the upper roll 11, being the main driving shaft of the machine. secured the main driving pulley 13. as indicated by broken lines in Fig. 1. Theshaft 14 of the lower roll 11. carries a gear 15 meshing with an intermediate gear 16 which in turn meshes-with a gear 17. on the shaft of the roll 9. as indicated in broken lines in Fig. 1, thereby operating the carrier apron 8. The shaft 12 is revolved'to move the 'This stripper 19 is operated by a pulley 20 connected by a belt 21 to a pulley 22 on the shaft 12, as indicated inv broken llnes in Fig. 1., thereby revolving the stripper 19. in the direction of the arrow 0. The mixed fiber is removed from the spiked apron 10. by a revolving dofi'er roll 23 or other well'known the shaft 12 with a stepped pulley 43 on the means. Above the'carrier apron 8 at the feed end of the machine is formed an aux- '30. 30., journaled in hearings in the side frames 7. 7 The shaft 31 of the lower roll 30 carries a gear 32 meshing with a gear 33,

which in turn meshes with a gear 34 on the shaft of the back roll 28. .A gear 35 on the shaft 31 meshes with a pinion 36 on a shaft 37 journaled in bearings in the side frame 7. This shaft 37. carries a pulley 38 as shown in Fig. 1. A shaft 39, is journaled in hearings in the side frames 7. 7. and carries a revolving dofi'er roll 40 in a position to strip a predetermined amount of waste cotton from the spiked apron 29, as shown in Fig. 2. A belt 41 connects a pulley 42 on shaft 89 and a belt 44. connects the stepped pulley 43 with the pulley 38 on the shaft 37. thereby driving the dofier roll 40, the spiked apron 29 and the feed apron 27. A comb 45 is secured to a shaft 46 'ournaled in bearings in the side frames 7. in a position to strip a redetermined amount of the waste cotton ff'om the spiked apron 29. as shown On the outer end of the shaft 12 is in Fig. 2. .A cam 47 on the shaft'39 operates through an arm 48 on the shaft 46 as indicated by broken lines in Fig. 1, to give an up and down motion to the comb 45. A presser plate 49 in the auxiliary hopper 24 is secured to a shaft 50 supported at each end in the side frames 7. 7. This presser plate 49 holds the waste cotton against the face ofthe spiked apron 29 andmay be adjusted for .position by any well known means. The end 26 of the auxiliary hopper 24 and the presser plate 49'forms an entrance opening 51 to the hopper for the waste cotton. The lower carrier apron 8 extends outward beyond the auxiliary hopper 24 and forms an endless moving surface to receive the raw cotton and feed thesame to the machine through an opening 52 between the lower carrier apron 8 and the auxiliary hopper 24, as shown in Fig. 2.

In the operation of my combined fiber feeder and mixer, raw cotton 53 is placed on the outwardly extending portion of the carrier apron v8 and waste cotton 54 placed in the auxiliary hopper 24, through the entrance 51. .Through the operation of the mechanisms described the raw cotton 53 is fed to the spiked apron 10 through the opening 52, and simultaneously a uniform and a predetermined amount of waste cotton is fed from the auxiliary hopper 24 on to the raw cotton, as illustrated in Fig. 2. By the action of the carrier apron 8 and the spiked apron 10 the raw and waste cotton are thoroughly agitated and mingled together into a uniform mixture of raw and waste cotton 55 which forms into a mass that revolves in the direction of the arrow f. The spiked apron 10in addition to mixing the cotton disintegrates the mixed cotton from the mass, and in connection with dofier roll 23, feeds the same out of the machine,

the amount of disintegrated mixed cotton coming from the machine being governed by the speed of'the revolving stripper 19, and the amount of waste cottonfed to the raw cotton being governed by the reciprocatoryspeed of the comb 45;

By the use of my improved fiber feeder and mixer a more perfect mixture of waste cotton with raw cotton or one fiber with another fiber is obtained and a more perfect yarn of mixed fiber is produced than .has heretofore been obtained.

I do not wish to confine myself to the construction shown as various modification in construction could be used to accomplish the same result. a I
