Specification of Letters Patent.

Patented Sept. 7, 1909.

To all whom it may concern: I

Be it known that I, JAMES SOU HWELL, of the city and county ofProvidence and State of Rhode Island, haveinvented certainnew and useful Improvements in 'Combing-Machines; and I do hereby declare the following specification, taken in connection with the accompanying drawings, forming a part of the same, to be a full, clear, and exact description thereof.

The invention relates to circle combs of the type commonly known as the Noble comb, in which there is a large circle comb and two small circle combs with two sets of drawing-off rolls for drawing OK the fibers of wool from the large circle comb at opposite points, and with one set of drawingolf rolls for drawing 0]? the fibers from each of the small circle combs. I

Ordinarily each set of drawing-off rolls comprises two rolls both fluted, but only one of which is positively driven, an endless apron being employed which passes between the two rolls and around the non-driven roll and one or more other idler rolls. With such arrangement'much difliculty has been experienced, if the sliver happens to break, in the liability of the broken end of the sliver being taken up by and wound upon the exposed positively driven roll. As said roll is necessarily arranged in close proximity to the teeth of the comb, the winding up of the sliver thereon speedily results in a jamming or bending of such teeth and a se-; rious damage and" injury to'the machine; Attempts have heretofore been made to prevent this winding up of the broken sliver upon the drawing-off roll and the damage resulting therefrom by providing a third fluted roll loosely mounted in proximity to the drawing-off rolls and adapted to be rotated by frictional contact with the apron, the idea being that such third loosely mounted roll would serve to lead the sliver away from the exposed drawing-off roll. It has been found in practice, however, that the employment of such loosely mounted third fluted roll. isineffectiveto produce the desired result, and that said third roll,-instead of always leading the sliver away from the exposed positively driven roll, frequently operates to carry the broken end of the sliver to such positively driven roll, andso that it will be wound up thereon, with resulting damage and injury to the comb, the same as when such third roll was not employed.

The present invention consists primarily in the employment, in connection with the pair of drawing-off rolls and endless apron, of a third roll located on the delivery side ofsaid drawing-off rolls and in positively driving said third roll, but at a slower speed than the positively driven drawing-off roll and endless apron are driven.

A further feature of invention consists in making this third positively driven roll plain instead of fluted, said plain roll being likewise driven at a slower rate of speed than the drawing-off rolls and endless apron.

Referring to the drawings, Figure 1 is a plan view of a wool-combing machine of the type referred to showing the arrangement of the combs, the drawing-off rolls and the endless aprons, and showing my invention applied thereto. Fig. 2 is a plan view on a larger scale of a bracket for supporting the third roll in position and showing the arrangement of gears for driving said third roll. Fig. 3 is a side view, partly in section, of said bracket with the third roll mounted thereon.

1 represents the large circle comb and 2, 2, represent the two small circle combs.

8 and 4 represent the drawing-off rolls for the large circle comb, 3 being the positively driven roll and 4 being the loosely mounted roll.

5 and 6 represent the endless aprons for conducting the slivers from the large circle comb to join the slivers from the small circle combs. 1

The liability of breakage of the sliver exists chiefly, if not entirely, in the case of the slivers from the small circle combs, and in the drawings the invention is shown only in connection with the drawing-off rolls for the small circle combs. If desired, however, the invention may also be employed in connection with the drawing-off rolls for the large circle comb. As the construction is the same in the case of the drawing-01f rolls for each one of the two small circle combs,

it will be sufficient to describe said constructlon 1n COHIIGCJLIOH w th one set of such drawing-off rolls, the several parts being designated 1n the drawings, however, by the same reference numerals 1n the case of both sets of such drawing-off rolls.

' 10 rigidly mounted in the adjustable bracket ll. This bracket 11 is adjustably secured to a fixed part of the machine by means of a clamp-bolt. 12 taking into the slot 13 formed in said bracket. By this construction the position of the roll 9- with relation to the roll 7 and the apron 6' may be readily adjusted. In the drawings the roll 9 is for out of contact with the sliver. It will be understood, however, that in the ordinary operation of the machine the roll 9 to be so adjusted as to he in contact with the sliver and preferably so as to produce more or less nip on the sliver between said roll and the apron. and thereby serve to draw the sliver away from the roll- 7.

The drawing-oft roll 7 is positively driven by suitable gearing (not shown)- inthe usual manner. The third roll 9 may be driven by any suitable means which will impart to said roll a speed slower. than the speed of the drawing-off roll 7 and of the endless apron 6, the speed of said apron being the same as the speed of the roll 7 Inthe drawingsthe roll 9 is shown as driven fi'om I the-gear It of the small circle comb. Said roll 9 is provided at its lower end with a gear 15-, which meshes with a gear 16 loosely mounted on a stud 17 secured toan arm 18 of the bracket 11, said gear 16. in turn meshing with the gear 14 of the small circle comb. The ratio of these several gears: is to be such that the-roll 9 will be revolved at a slower speed than the speed of the roll 7 and the endless apron 6.

7 With the construction above described the operation is as follows: With the roll 9 properly adjusted with relation to the roll sliver, as it leaves the apron 6, passes besliver, instead of being, caught up by and 'apron 6.

wound upon the drawing-off roll 7, will be carried along between the roll 9 and the surface speed of said apron is greater than the surface speed of the roll 9, the broken end of the sliver, instead. of being caught up prevented from being carried by the roll 9 on to the roll 7 and being wound thereon. The broken end of the sliver, after being 9 represents a third roll, 7

led away from the rolls by the apron, will drop down where it will do no harm, even if the breakage of the sliver should not be promptly discovered and the machine stopped.

W hil'e it is preferred that the roll 9 shall be a plain-surface roll, this is not absolutely essential, as substantially beneficial results may be obtained even if said roll is roughened or fluted. \Vith the roll 9 thus roughened or fluted, however, it has been found that there is more or less tendency of the roll 5 to. back up. the sliver between the roll 9 and the roll 7, and it is for this reason that it is preferred to provide the roll 9 with a plain smooth surface.

\Vhat I claim as my invention and desire to secure by Letters Patent is: convenience shown in an ad usted position 1. In a combing machine, the combination. of apair of drawing-off rolls, an apron driven by one of said rolls, a third rolllocated on the delivery side of said drawingoff rolls and adapted to prevent the winding of a broken sliver upon one of said drawing-off rolls, and means for positively rotating said third roll independent of the apron.

In a combing machine, the combination of a pair of drawing-off rolls, an apron passing between said rolls and driven by one of them, a third r011 located on the delivery side of said drawing-oh rolls and adapted to I prevent the winding of a broken sliver upon one of said drawing-0ft rolls, and means for positively rotating said third roll. at a different speed from said apron.
