Letters Patent No. 114,064, dated April 25, 1871.

IMPRovEMi-:N'r IN DRAWING-FRAMES.

The Schedle referred to in these Letters Patent and making part of the time.

' ing-Frames and other machines in .which the sliver is traversed; and I do hereby declare that the following lis a correct description of rthegsame, reference being had to the accompanying drawing making part ofv this specification, and to the letters of reference marked thereon. i

Figure 1 is a plan.

Figure 2 is an end elevation.

Figure 3 is a side elevation.

Figure 4 is a view of top and bottom rolls of a drawing-frame, showing the b0sses,where the weight is applied, 85e.

In all the drawing-frames with which -I am acquainted the sliver-guides are fixed to the traversingbar, and they are usually upon one rod or bar, in which latter case the weight will not bear equally upon the slivers, for by reference to iig. 4 it will be seen that when one sliver is at a, under one boss, it is very near the weight, while the sliver to the other boss is at b, or furthest from it, and consequently has the least weight to support, having the longest arm ot the lever. Manufacturers have been desirous of' obviating this diliicnl-ty, and contiivances have been resorted to for effecting this object.

By my invention I produce a combination which is inexpensive, easy-working, operates very perfectly, and takes but little rooln.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

The heart A, which, unlike a crank, gives a uniform motion to the traversing-rods, the worm-wheel B,.and worm C are as they are usually made ondrawingframes.

In practice "a toothed wheel is placed on the wormshaft in place of the hand-wheel ou the-drawing, and gears into another wheel on the back roll ot' the draw-` ing-frame and is driven by it.

The rod E, which usually is nearly the length of the drawing-fram e, or is connected with another single traversing-har which is so, has xed guides upon it, but by my arrangement is connected with a short crossbar, H, which is pivoted in the center by the stud I, and. connects with the two traversing-bars or Arods L M, which have adjustable sliver-guides N O fastened to them, and which must travel in opposite directions.

The distance traversed by the rods L M is regulated by means of the slotted part F and the pin G.

The part F is secured to the end of the rod E, and its motion is governed by the throw of the heart A; but the pinG is adjustable iu the slot g in the crosshar H, and by this means the traverse of' the sliverguides is governed; for whenp'in Gis fixed nearer the' center or pivoting-stud `I ofthe cross-bar H the traverse will be increased, and when fastened toward the other end of lthe slot it will be diminished.

The arms J and K, at their upper parts, are secured to the guide-rods L and M, and at their lower extremities they are coustructed'so as to play freely in slots in the ends of the cross-bar H, thus accommodating themselves to the arcs which the cross-bar makes as it turns upon its pivoting-stud I.

The sliver-guides are.usually made of two pins fixed viu a traversing-bar, but by my invention are made adjustable on the4 rods, and this, I believe, is one of the mostuseful features of my invention.

The stands P are for supportingr the traverse-rods, and are so made that the rods 4L and M will lslide freely through them.

On the drawing-frames the rods L M are extended so as to traverse the guides for all the bosses to the back rolls of the drawing-frame. The distances from center to center of the bosses are greater than from center to center of the guides on the drawing, and suchy that the-sliver-guides can all be in a line between the two rods, each sliver-guide being turned half-way round from the position shown.

I do not claim moving the sliver-guides together to the center of therolls and afterward receding from it, as that has been patentedby Thomas Winn nu the 6th of September, 1870; but, not being aware that any mechanism has ever been shown for traversing onehalf the sliver-guides'in an opposite direction from the Vother half, with uniform speed, with adjustable sliverguides, and-a governor of the traverse, so as to avail of the wear ou the whole length of the bosses, whether long or short,

What l claim as my invention, and desire to secure by Letters Patent, is

The mechanism herein described, consisting of the combination of the heart A and rod B, the slotted part F, the adjustable pin'G, the cross-bar H -pivoted in the center, the arms J and K, the rods L and M, the adjustable sliver-guides N and O, substantially as described. v
