'Letters Patent No. 109,430,` dated-November 22, 1870.
IMPRVEMENT IN DRAWING-FRAMES.
The Schedule referred to in these Letters Patent and making part of the lame.
' To all whom it may concern:
Bc it k-nown that l, Gnlrnnns l. Lnnvrr'r, of New York, in the county and State of New York, have invented a new and improved Drawing-Frame for Flax, Combed W'ool, and other Fibers; and I do hereby declare thatfth'e following is a full, clear, and exact description the-rect', which will enable those skilled in the art to .understaiul and usc the. saine, reference being had to the accompanying Hdrawings forming part of lthis specification, of which Figure lis a longitudinal section of my improved iiax drawing-tianie through the line y y,.tig 3.
Figure 2 is a transverse section through the centvr-pin of the guide-rollers in the line x af, tig. 1.
Figure 3 represents a general plan.
Similarletters indicate the same parts in all thedrawings.A v y My invention relates to au improved machine for drawing dax, combed wool, andother'fibe1s;'and
It consists in the application and arrangement of two belts traveling'togethcr over rollers, and operating in connection with a pressing' rolleror rollers, in such manner that the sliver or ribandbf fibers formed bythe ordinary spreading ii'aniefshall bcconveyed by the belts to the drawing-'rolls whilewthey exert an equal pressure on all't'he parallel fibers ot'longer or shorter length, andhold or detain them during the operation ot' drawing, for the purpose of producing a liner sliver or riband of great regularity, free from bunches, which shall make a level and superior yarn or thread.
These detaining belt-s are kept in placeto travel straight onv the rollers by means ofseltadjusting guide-rollers, as hereinafter described.
A is the frame-work of the drawingfiachiue, similar in construction to that of au ordinaryGilpin drawing-frame.
Bis the loose press or top drawing-roll, which is held down as usual upon the lower drawing-roll C by Va weight, l, attached to a swing-yoke, a., suspended on the journals ot the top roll.
Back of the dra\vingrolls B C are two horizontal leather Aor rubber belts,c c', which traveLuear together and in order to equalize the pressure ofthe belts lengthwise a tension or press-roller, y, is placed between thenpper and lower sides of the upper belt to bear it down closely upon, the lower belt by means of a weight, 4, attached to a swing-yoke, It, suspended on the journals of the tension-roller.
Ono or more tension-rollers may be used to keep the belts close together.
The sliver or' riband of flax or other fibers is introduced as shown in Iig. 1, at the rearA endlof the belts, so as to be conveyed lengthwise between them to the drawing-rolls B C, as the belts travel. While the sliver Ais thus carried forward by the belts, the upper one, c, bears down upon the libers equally throughout their-,whole length, and thus holds or detains them at all pointsI alike, whether the fibers are longer or shorter, while the sliver is drawn or reduced evenly by the drawing-rolls.
Above the upper belt c and below the lower belt c are guide-rolleis 'i t', made of India rubber or other proper material, extending across and bearing against the belts.
These guide-rollers are hung by journals in yokeframes It k,"wl1ich are pivotedou center-pins m m',
that arescrcwed through tixed cross-pieces n at', se-
.s .sQproj ect from the yoke-trames 7.: It', curving in such a ina-nner as to extend beyond the edges of the belts and lie. close along side of then.
Whenever any irregular movement takes place by the shifting of the belts to one side or the other of the rollers on which they travel, their edges touch the prongs s s', which then act as levers to turnthe rolli 2. The guide-rollers 'it' and fingerss s', hungon the pins Jmy m', as described, in combination with the two endless traveling belts c c', constructed and operating as dcscribed.
