e To all whom it may concern."

Be it known that we, THoMAs BnLLwooma eitizen of the United States, residing at Methuen, and HOLLAN GARTH, a citizen of the United ,States, residing at Lawrence,

both in the county of Essex and State. of

bers, dafidies, reducers, slubbers, finishers, weigh boxes, first and second drawing boxes or to any other machines of a similar type. In such machines, a plurality of ends of sliver pass together through theiloack rolls so called and over carrier rolls'to the front rolls which deliver them to fliers upon which they are twisted. Between the back rolls and the front rolls, the sliver is drawn out and in the usual form of machine it is found that it.is spread out to such an extent that,

it loses some of its cohesion. On account of this, either from electrical action or for some other reason, certain fibers or flyings adhere to the front rolls and, if not removed, eventually accumulate and latercomeofi in bunches. Such bunches being worked into the yarn form imperfect work or slubs. To remove these flyings there is often located below the lower front r611, which is usually of metal and fluted, what is known as a rub her which catches the, flyings or rubber Waste So called. This rubber must be frequently removed and cleared from time to time by hand. The upper front roll which is usually of leather can be cleaned from the front of the machine by handafter suflihient waste has accumulated.- On some machines, a clearer bar is used in front of the upper front roll so as to bring the sliver away from the lower front roll thereby reducing the tendency for the rubber waste to stick thereto. It is supposed also to prevent waste or flyings from sticking to the top roll.

In 1 the drawings, Figure 1 is a section from the side of the back and front rolls of 3a finisher. Fig. Q'Aj lS a perspective View of the same with the upper front roll removed.

10, .11, 12 and 13 are the back rolls.- H is the upper leather covered-front roll and 15 is thelower front fluted metal roll. Between the front rolls and the back rolls are the revolving carrier rolls 20, 21, 22 and 23 whichsupport the sliver A and assist in carrying it along to the front'rolls. In these machines, aguide behind the back rolls and not shown but having a lateral movement moves the sliver from side to side so that it will not Wear out any one part of the various rolls. 1 30 is the brace bar WhlCll extends between.

the stand sections of the machine as usually 1 Our device may consist of a wire condenser guide B such as is shown in Fig. 7. Such wire guide has parallel legs 40, and 41 which preferably are formed with bows 42 and 4.3 near the bottom and come together to form an eye 44' through which loosely and through a hole 31 in the bracebar 30 just underneath the point where the sliver passes, extends a screw or pin 45. Such wire legs 40 and 41 may be adjusted toward and from each other in a direction'par'allel with the front and back rolls by bending with pliers or with the fingers.- The bows 42 and V 43 facilitate such adjustment and they should be offlexi'ble wireso that when bent they willretain their new position.

We prefer to place our condenser guide between the revolving carrier rolls although it may be placed between the front carrier roll and the front rolls if the stock used has a long staple. With short staple however, the front carrier roll must be so 7 near the front rolls that our condenserguide must be placed between the carrier rolls.

Our condenser g ide isvpreferably'so pivoted that it can move from side to side as shown by the dotted lines in Fig. 7 to accommodate itself to the movements of the sliver. It m ght however, be .so arranged as to slide Sidewise if desired.

We prefer th form of adjustable condenserguide G'shown in detailFigs.- fraud 6. The base. 50 which has a pivot hole 51 .has also a leg 52 anda shoulder :or arm 53 at right angles thereto and has also an' adjusting slot at right angles to said 'leg 52. i'lhe movable leg 55 corresponds with leg 52 and has a ridge 56 adapted to slide along shoulder 53. lit is bolted to the 60 passes through a hole 62 in brace bar 30 s and through a sleeve 61 which passes loosely through a hole 63 in base 50 of guide C. A nut 64 screwed on bolt 60 and against sleeve 61 holds the parts in position. Guide C can rock freely on sleeve 61. p

By the use of our device, the sliver is condensed laterally and thus passes between the front rolls and leaves them in a much more compact form. The result of this is that there is practically no rubber. waste andvthe rubbers as well as the clearer bars can be dispensed withentirely. As our device prevents fiyings or rubber waste, there are no slubs or bunches inthe yarn after it is- 25. twistedby the flier D. a

Our device consists essentially of a thin guide with thin legs adjustable toward and "from eachother in a direction parallel with the front rolls and back rolls and located between such rolls, said guide preferably nsane? being pivoted to the brace bar to swing la erally in a plane parallel with the axes of said rolls.

Uur device may be used on any machine for drawing worsted sliver or it may be used on any machine for drawing any fiber such as cotton ramie, or silk.

What We claim as our invention and desire to cover by Letters Patent, is:

In a machine for drawing'worsted sliver,

. with a leg fixed thereto and a shoulder in which is a slot at right angles to said leg together with a movable leg having a ridge adapted to slide along the shoulder and ad- .justably attached to the base by means otia bolt which passes through the slot therein and a nut said condenser guide being so ally as described.

In testimony whereof we hereto afix our C. R. PERRY? WM. Jnsir.

pivoted to the brace bar as to swing later
