IMPROVEMENT IN MACHINES FOR. MAKING ROVING.

Specification forming part of Letters Patent No. 37,504, dated January 27, 1863.

To all whom it may concern:

Beit known that I, NOAH E. HALE, a citizen of the United Statesof America, and a resident of Nashua, in the county of Hillsborough and State of New Hampshire, have made a new and useful invention, having reference to machinery for making roving, such` invention also being applicable to various other machinery of a like character for producing yarn; and I do hereby declare the same to be fully described in the following specification, and duly represented in the accompanying drawings, making part thereof.

Of the said drawings, Figure lis a top view, Fig. 2 a rear elevation, Fig. 3 an end elevation; and Fig. 4 a vertical and transverse section, of two sets of drawing-rollers, with my invention applied to them,their trumpets and belt-shifter, the said drawing-rollers being supposed to make part of an ordinary drawing-frame.

rIhe nature of my invention or improvements consists, rst, in the combination of a gravitating jaw and a yarn-rest or stationary jaw with the movable trumpet-guide and its stop-motion and, second, in a new or improved stop motion or mechanism applied to the armed rocker-shaft, one of the draft-rollers, and the latch of the belt-shifter, the purpose of my invention or improvements being to produce a stop-motion with which the friction on the sliver may be uniform and the machine be stopped in action on the breakage of a sliver.

In order to hold forward the trumpet-guide, I do not depend on its friction on the sliver, as such friction will vary as the sliver may vary in size but I use a trumpet-guide, havinga hole or sliver-passage so large that a sliver may pass through it readily and easily without creating any forward draft on it, except it be by the gravitating jaw and its stationary fellow jaw. I would remark that by the term stationary, as applied to the lastnamed jaw, I mean that the said jaw is stabeing supported on thc upper and shorter arm of a lever, B, whose longer arm is furnished with a foot, d, extending from it, as shown in Fig. 2. Each lever D has the form exhibited in the drawings, and is hinged at its fulcrum to a rail, C, of the frame D of the draft-rollers E E and F F', there being a guide-rail, G, in rear of the draft-rollers or between them and the trumpet-guides. The two slivers, after being run through the two trumpet-guides, pass together through one hole or passage, b, in the guide-rail G, and from thence are run between two rollers of each of the sets of draft-rollers. In rear of each trumpet-guide there extends a stationary jaw, c,whose upper surface is even wit-h the lower surface of the trumpet-hole. There is also hinged to the trumpet and over the stationary jaw a movable and gravitating jaw, d, the hinge thereof being arranged in such manner as to enable the jaw d to play in a vertical plane. The sliver, after passing through the trumpetguide, goes between the two jaws c d. It rests on the lower jaw and is borne down upon it by the weight of the upper or movable jaw. The friction ofthe jaws on the sliver is, therefore, constant and not likely to vary much, and should be sufficient to cause the draft on the sliver to draw the trumpet-guide and its lever forward and in a manner to keep the foot a out of contact with a vibratory arm, e, extending from a rock-shaft, H, arranged as shown in the drawings. On the end ofthe said rock-shaft H there is a wheel or disk, I, provided with two tappets, f g, which project from its side and underneath the two arms It i of a tri-armed lever, K, which is jointed to the upper end of the lifter-rod L, supported within and passing down through a vertical postor standard, M. A spring, n,serves to force downward the lifter-rod, which is provided with a stud or arm, k, extending underneath a gravitating latch, O. The said latch is applied to the frame D and operates with the belt-shifter P, which is a slide-bar carrying a staple, l, for the driving-belt of the machine to run through, A spring, m, operates the bar in a direction which will cause the belt to be shifted from the fast to the loose pulley of the machine. Furthermore, the latch when in a notch, y, made in the belt-shifter P, (see Fig. 5, which isa top view of the belt-shifter,) keeps the belt-shifter in a position to cause the belt to run on its fast pulley. A connecting-rod, R, is jointed to the upper arm, m', of the tri-armed lever K, and also to a crank or crank-Wheel, S, applied to the shaft of the lower one of the front set of draft-rollers.

While the machine is in operation, and each of the slivers reinains'nnbrok'en, each trumpetlever will not only be drawn out of the path of movement of the arm e of the rock-shaft H, but the said rock-shaft will have reciproca-ting rotary movements imparted to it, which will be produced by the action of the tri-armed lever K on the tappetsfg of the disk 0r head I; butin case cfa breakage ofa sliver in rear of thc draft-rollers the trumpet-lever ot' such sliver will be caused by its gravitating power to assume such a position as will carry its foot into the path of movement of thc arm e and so as to arrest the mot-ion of the said arm and that of the rock-shaft H. The consequence of this will be that the tri-armed lever will be caused to so press on one of the tappets as to rise off the other and elevate the lifter L, Which in turn Will force'the latch O out of its notch in the belt-shifter P. Such having taken -place the belt-shifter will be driven forward therefor, the tri-armed lever K, latch-lifter L,A

and disk I, with tappets fg, the same being applied to the armed rocker-shaft H, one of the draft-rollers, and the latch of the beltshifter in manner and so as to operate substantially as specified.
