SPECIFICATION forming part of Letters Patent No. 500,113, dated June 27, 1893.

Application filed October 11, 1892. Serial No. 448,524- (No model.) Patented in England April 15, 1891, No. 8,444.

To all whom it may concern..-

Be it known that we, WILLIAM HALL (3001; and JAMES HARRISON, subjects of the Queen of Great Britain, residing at Manchester, in

the county of Lancaster, England, have invented certain new and useful Improvements in Apparatus for Imparting a Variable Motion to the Traverse-Rods in Machines for Preparing and Spinning Fibrous Materials,

[0 (for which we have obtained Letters Patent in Great Britain, No. 6,444, bearing date the th day of April, 1891,) of which the following is a specification.

This invention is designed to produce a re- 15 ciprocating motion varying in the distance traveled at each stroke or varying the point upon which the direction of movement changes at the end of each stroke, to be applied to the traverse or traverse rod of spin- 2o ning or other similar frames, with the object of preventing the wearing of grooves in, or the cutting of the leather covered rollers between which the rove or sliver of material passes.

It consists essentially in constructing the apparatus with two independent eccentrics which act independently of each other through two separate links or connecting rods affixed to a bracket pivoted to the traverse rod.

0 It will be fully described with reference to the annexed drawings which show apparatus constructed in accordance with the invention;

Figure 1 is a front elevation; Fig. 2, back elevation; Fig. 3,-pla'n; Fig. 4, transverse sec- 3 5 tional elevation through the eccentrics on line w0c,' Fig. 5, transverse sectional elevation on line y-y; Fig. 6, front elevation of modified form or arrangement of the apparatus; Fig. 7,

back elevation of same ,Fig. 8, plan of same 3 40 Fig. 9, transverse sectional elevation on line w-w; Fig. 10, transverse sectional elevation on line z-z.

On a fixed bracket A placed on the roller beam or other convenient position in the ma- 5 chine, we mount two separate eccentrics B B working independently of each other, and

each fitted with a connecting rod or link 0 C by which the motion of the two eccentrics is conveyed to a common bracket D, pivoted to the traverse rod E. Each of the eccentrics we prefer to form on the side of a toothed wheel which receives motion from a worm or other gear, and by which they are rotated.

Referring more particularly to Figs. 1 to 5, the two eccentrics B B are each formed on the face of a worm wheel F F and are mounted side by side on a stud f carried by the fixed bracket A. The two worm wheels vary in size by one or more teeth so that their relative position and that of the eccentrics is constantly varying. On the traverse rod E, is pivoted the bracket D, to which both eccentrics are connected by the rods or links O O. The bracket is pivoted at one end to the traverse rod, and at its other end is 55 pivoted the connecting rod 0', the connecting rod C being pivoted to it by a separate pivot at a convenient distance from the bottom of the bracket. The bracket D is provided with a longitudinal slot at its upper end, and is connected to the traverse rod E by a stud d, the position of which is adjustable in the slot. The stud d is fast to the bracket 1) and pivoted or free to rotate in the bracket e fitted to the traverse rod E. The ends of the connecting rods are each pivoted on studs 0 0' made fast in transverse slots. The throw or length of traverse of the rod E can be regulated or adjusted as required by altering the position of the studs (1,0 or c in their respective slots, so as to give a longer or shorter extreme traverse. The wheels F F are driven by the Worm G cut in or fixed upon the roller or by any other suitable arrangement.

Referring more particularly to Figs, 6 to 10, the same description will in most part apply to the modified form of the apparatus, but instead of both eccentrics B B and their respective wheels being mounted on the same stud or center, they are mounted upon separate studs, and the wheel F' driven from a wheel F connected to the worm Wheel F, as by this means greater variation or difierence in the speed of the two eccentrics B B can be obtained. In the drawings a star or stud Wheel is shown at F connected to the eccentric B, which is actuated by a stud or projection f" on the wheel F by which the wheel F, and eccentric B are moved forthe bracket D in the same direction, and at another time one eccentric will be throwing its connecting rod in one direction, and the other eccentric its connecting rod in the 0pposite direction, thus communicating a constantly varying traverse to the end of the bracket D and traverse rod E. In the second example, the constant movement to the traverse rod isefiected by the eccentric B and connecting rod 0 while the end of the connecting rod 0' acts as a fulcrum, the position of which is altered at each revolution of the eccentric B by the movementgiven to the eccentric 13 thus communicating a varying motion to the end of the bracket D fixed or connected to the tra'verse rod E.

We wish it to be understood that we are well aware that two eccentrics have been used to vary the traverse where one eccentric has been placed inside the other or to act directly upon the other, and that such have been actuated by two worm wheels of diiferent diameter gearing together into a single worm, and we do not make any claim therefor.

What we claim as our invention, and desire to protect by Letters Patent, is-

1. An apparatus for imparting a variable motion to the traverse rod of preparing and spinning machines provided with two independent eccentrics working separately and two separate connecting links through which the movement of the eccentrics is independently transmitted through a common bracket to the traverse rod in combination with a common bracket to which they are pivoted, the traverse rod to which the bracket is attached, and the worm wheels and worm which actuate the eccentrics substantially as described.

2. In apparatus for imparting a variable motion to the traverse rod of preparing and spinning machines the combination with the traverse rod 'of two separate independent eccentrics the relative positions of which are constantly changing, two separate independent connecting rods through which the movementof the eccentrics is transmitted, two worm wheels afiixed to the eccentrics,a-worm aifixed to the roller shaft and a common bracket attached to the traverse to which the connecting rods are attached in differentpositions substantially as described.

3. In apparatus for imparting a variable motion to the traverse rod of preparing and spinning machines, the combination of the two separate independent eccentrics B B which work independently of each other, the worm wheels F F which are attached to and actuate the eccentrics, the two separate links or connecting rods 0 0 through which the movement of the eccentrics, is transmitted and the bracket D affixed to the traverse rod common to the two connecting rods, with the 'worm G on the roller and the traverse rod E substantially as described.

4. In apparatus for imparting a variable motion to the traverse rod of preparing and spinning machines, the combination of the traverse rod E, the actuating worm G on the roller, the bracket A, the worm wheels F F which are attached to and actuate the eccentrics,the independent eccentrics B B, the stud f which carries the eccentrics, the two separate connecting rods 0 C which transmit the movement of the eccentrics, the bracket D to which the two connecting rods are attached in diiferent positions, the studs 0 c with which the ends of'the connecting rods engage and the bracket 6 provided with stud d by which the bracket D is attached to the traverse rod.
