showing the parts in one position,
This inventionis peculiarly applicable to textile machines or frames in which there are rollers covered with leather or other similar material which deliver yarn or roving. Such rollers are especially used on spinning, twisting, and roving frames.
Particularly with wool, it the yarn or roving passes through at the some point, the leather roll would rapidly be out and rendered useless. Therefore, on such n1achines there is generally what is known as a traverse motion comprising a traverse bar which extends from one side to the other of the machine, with suitable guides which cause the yarn or roving to move back and forth longitudinally of the roller. 'lherehy the wear is distributed and the roll is not cut as rapidly as it the wear came at one place. Such a traverse inotion is generally produced by means of a cam or eccentric which, for the purpose this description, may be regarded as substantially the same, and as the traverse motion nioves haclt and forth there is such a dwell at theends that the rol are worn unevenly and frequently cut. V
-lEspecially when clninging from line to coarse work, the rolls are frequently cut, making had work. To partly overcome this it is customary to increase the pressure on the rolls, which requires more power to drive them. Such pressure tends to flatten out irregularities but is objectionable on account of the extra power required.
The purpose of this invention is to more evenly distribute the wear by shitting the turning points of the traverse motion so that such turning points will be distributed. along the face of the roll.
I believe that this invention is not only applicable to textile machines, but is a new mechanical motion, and l therefore claim it as such.
in the drawings, Figure l is an elevation of niy device applied to the traverse motion cam in common use on a spinning 'lraine,
Fig. 2 is a diagram showing the manner lollower.

in which the traverse shifts as the eccentrio follower revolves.
Fig. 3 shows another position of the parts.
Fig. 4t shows a modification oi the cam or eccentric and a slight modification of the follower,
Fig. 5 shows another position of the cam and follower shown in Figs. 1 and 3.
lo the drawings, it represents the frame of a textile machine of the spinning frame type, and a bracket attached thereto by bolts or rivets 10. The bearing C is attached to bracket B by means of bolts or rivets -ll and supports a driving shalt D, which is driven by means of a gear G and has lined to it the cam F shown as rigid thereon hy means of a spline 12. R, R are the delivery rolls.
The hearing" for shaft D is a fixed 'bearing on. the frame. Instead of the usual do pression in corn ll, ll provide a notch with an easy slope 20 and a sharp slope 21 so located that the sharp slope 21 travels forward and will engage the follower in a manner to be described.
ll is the traverse bar of the traverse motion oil? well known forth, and to this is adjustably attached the bracket K havin a slot l3 through which passes the bolt 14 for adjustment. he spring El connectedto the frame at ll and to bracket K at 16 tends to pull the traverse motion. toward the right when permitted.
Bracket ll: has a slot 15 in whichis a stud ll having a. flattened portion 2t and a head 25 held adjustably in position by a nut 27. V
llnside the head 25 and revoluhle on stud it, is the follower ll l,-vvhich is substantially an eccentric with a plurality ot'tceth 22, 22, having; concave portions 23 between. This eccentric follower is revoluhle on the pivot,
which is stud l5, movable'with the traverse motion, and is kept in engagement with the cam or eccentric F by the action of spring 7 As the ain 1 revolves, it forces the fol lower and traverse motion away up to the point of the cam and allows it to recede as the spring pulls it back to the notch 20, 21. /Vhen the notch comes around, aS shown. in 5, it engages a tooth 22 and moves the eccentric follower one tooth. The op eration is repeated as the cam revolves the in thedrawings thc'fiollowcr is shown as having eightteeth, and it will be seen that follower is revolved once. The result is that the traverse motion moves on the rolls, as shown between the points 30 and the points 31 in Fig. 2.
In Fig. 4, I show in place of a heartshaped cam the eccentric P carried by the fixed pivot or shaft D and having anotch 40. The throw of this cam is shown as less than F.
I also show the movable pivot 26 for the follower T as smaller and nearer to one edge, so that its throw will be larger than that of follower M.
Itwill readily be understood that by changing the throw of the cam and follower different lines of wear on the rolls can be established. This can be done by removing the cam or follower, or both, and replacing one, or both, by one of a different size or shape. v
In Fig. 2, 7 represents a traverse guide carried by traverse rod H of a traverse motion. The zigzag line 30, 31 indicates the shifting motion of traverse eye 7. The length of each line 30, 31 is determined mainly by the throw of cam F, and the general curve of the zigzag line by the throw of the follower. It will be understood that the motion of the rolls is much more rapid than that of the traverse motion, so that the zigzag line in Fig. 2 is merely diagrammatic. As a matter of fact, the rolls R, R revolve in many cases several times while the traverse motion is moving once back and forth.
I claim: I
l. The combination with a spinning machine having a frame, rolls and a traverse motion including a traverse bar, of a cam having a notch with an easy slope and a sharp slope so located that the sharp slope travels forward, said cam being revoluble in a fixed bearing on the frame. with a )ivot movable with the traverse bar, a fol ower eccentrically revoluble on said pivot and having its periphery formed of a plurality of teeth of such form as to be successively engaged and turned by the sharp slope of the notch in the cam, and a spring between the frame and traverse bar to keep the cam and follower in engagement.
2. In a mechanical motion, the combination of a revoluble eccentric l1:t\'l1l; a notch with an easy slope and a sharp slopeso located that the sharp slope moves forward, with another eccentric in contact therewith having a plurality of teeth adapted to engage the notch in the first named eccentric, and means to keep the eccentrics in engagement.
In testimonv whereof I have allixed m signature.
