SILAS C. DURGIN, OF HOLYOKE, MASSACHUSETTS, ASSIGNOR TG LUMSELF, AND AMMON R. D'URGIN, OF NAPHU, NEV HAMPSHIRE.
DRNG-FRAIVIE FR DRATII'JG FBROUS MATERIALS.
Specification of Letters Patent No. 22,758, dated January 25, 1859.
To all whom it may concern:
Be it known that l, SILAs C. DURGIN, of Holyoke, in the county of l-lampden and State of Massachusetts, have invented au improved Mechanism for Drawing Slivers of F ibrous Material; and l do hereby declare that the same is fully described and represented in the following specification and the accompanying drawings, of which- Figure l, denotes a top view; Fig. 2, a rear elevation, and Fig. 3, a longitudinal and vertical section of it.
ln such drawings, A, A, B, B, C, C; denote three sets of cylindrical drawing` rollers arranged in front of a pair or set of conical drawing rollers, D, D, and made to operate like the draft rollers of a common drawing frame. ln rear of the set of conical draft rollers, l place a trumpet gage or hollow cone, E, which l support on a curved arm, a, extending from the top of an upright rod or shaft o, having a bifurcated arm, c, projecting from it in a direction about at a right angle to the curved arm. These two arms and the rod or shaft may be considered as a bent lever, E, of which the shaft is the fulcrum, as the two extremities of the shaft or rod are supported in bearings, CZ, (Z, extending from the two ends of a carrying lever, F, whose fulcrum is a horizontal shaft, e, arranged and supported in bearings, f, f, as seen in the drawings. rlhis carrying lever has a notched rack or arm, g, projecting from it and carrying a weight, 7L, for overbalancing, such arm, g, being arranged above the fulcrum or shaft, e, as shown in the drawings.
rllhe bifurcated arm, c, plays on or receives in the opening of its fork, a stationary vertical post or stud, z', a top view of the forked arm and the said stud being shown in Fig. 4.
When the lever, F, is moved with a reciprocating motion, the bifurcated arm will be vibrated on the stud, i, so as to move the lever, E', in such manner as to cause lateral movements to be imparted to the gage trumpet, E, such gage being moved rst from one end of either conical roller toward its other end and next back again from the latter to the former end of it. Furthermore, when the smaller end of the gage trumpet is nearest the smaller ends of the conical draft rolle-r itshould be in or about in a horizontal plane passing through the bite of their rollers. As it is moved away from such ends it will continue to rise above the bite. Q lllhile the above described mechanism is 1n operation the sliver to be reduced passes through the gage trumpet and between the rollers of the different sets of draft rollers. The opening of the smaller end of the gage trumpet should be just large enough to allow a sliver of the proper size for being drawn to pass through it. As the weight, It, causes the gage trumpet to move toward the larger end or' the upper conical roller, it will readily be seen that should the sliver while passing through the gage trumpet be larger in diameter than the proper size, it will produce friction in the trumpet to such extent as to cause the trumpet gage by the action of the draw rollers and the mechanism connected with the gage to be moved laterally and toward the smaller ends of them. Again should the part of the sliver that may be passing through the gage be less than the proper size for being drawn, the weight, 71, will cause the gage to be retracted and moved laterally toward the larger end of the conical draw roller. Now, as the delivery or the movement of the sliver, between the conical draw roller, is the slowesty when nearest their smaller ends and fastest when nearest their larger ends, it will be seen that any irregularity in the size of the sliver will be corrected by the sliver being moved laterally between the conical rollers to a position where its delivery by them to the cylindrical rollers will be at the rate necessary for uniformity of draft and the production of what is termed evenness of sliver.
rThe reason for arranging the steelyard arm, g, above the fulcrum of the lever from which it extends, may be thus described. As the gage trumpet is moved toward the smaller ends of the conical draw rollers, the sliver becomes bent laterally out of line, and of course exerts a lateral drag on the guide which continues to increase in proportion as deflection of the sliver increases. By arranging the arm g, above the fulcrum, the former, while its lever, F, passes forward beyond a vertical position, will be moved forward with the upper arm of the said lever so as to carry the center of gravity of the weight, 7L, nearer to the said fulcrum in a manner to diminish the force tending to lOl CII
retract the said lever. So while the upper arm of the lever is being drawn backward beyond the vertical line, the leverage or action of the weight on the lever will be increased, such being necessary to overcome the increase of lateral draft, which takes place on the sliver as it is moved out of its straight line and toward the larger ends of the conical rollers.
In my invention, the conical draft rollers are arranged between the gage trumpet and the cylindrical draft rollers. By this arrangement, the irregularities of the sliver are made to effect the movement of the trumpet gage before they pass into the bite of the rollers. I am aware, that a gage trumpet has been arranged in front of cylindrical drawing rollers placed in advance of a set of conical rollers and a separate sliding or movable gage for receiving the sliver in its passage to the rollers; also, that such gage trumpet and sliding guide had mechanism applied to them whereby by the forward and backward motions of the trumpet gage caused by the sliver in it, after the passage of the sliver beyond the draw rollers, the sliding guide has had lateral motions imparted to it so as to carry the sliver nearer to one than the other end,
of one of the conical rollers. A mechanism of this nature or one analogous thereto, I have understood to be described in the United States Patent No. 4847. I do not claim such, as my invention differs therefrom, first, in the arrangement of the gage trumpet with respect to the conical and cylindrical draft rollers such arrangement enabling me to dispense with the separate lateral sliver guide, my gage trumpet serving as the guide; second, the gage trumpet of' eef/ee my invention has lateral motions which is not thc case with the other; third, when the gage trumpet is placed in advance of the draft rollers an irregularity in the sliver passes between the rollers and beyond them before it can enter the trumpet, but with my invention, the reverse is the case, the whole of the irregularity being removed from the sliver, whereas, with the other, it would be but partially taken out.
Therefore what I claim isl. The arrangementof the conical draft rollers between the gage trumpet and the other reducing rollers, and supporting such trumpet by mechanism essentially as described (or the equivalent therefor) which will enable the said trumpet to operate both as a gage to the sliver and to guide it to the rollers and to be vibrated with respect to the conical rollers in manner and for the purpose as explained.
2. I also claim the combination of mechanism for supporting and vibrating the trumpet, the same consisting of the bent lever E, the overhalanee carrying lever F, and the stationary stud; and when such combination of mechanism is employed in manner and for the purpose described, I claim the arrangement of the supporting arm, g, of the weight 7L, above the fulcrum of the lever, F, in manner as and to operate with reference to the lateral drag of the sliver on the trumpet as specified.
In testimony whereof I have hereunto set my signature.
SILAS C. DURGIN.
