The pipe is snugly held in the bearings Each ring 11 is provided on its inner face with 31 but may be turned angularly by the use of a 55 a recess 14 (Figs. 5 and 6) and with outwardly handle 33.

Tubes 35 are inserted in the pipe and are longitudinally spaced at intervals corresponding to the spacing of the rings 11. Each tube has a bevelled open outer end, but the inner end thereof is closed as indicated at'36 in Rigs. 8 and 9. Each tube is also provided with anoperiiiig 37 in its upper side and adjacent its closed inner end 36.

Oil or lubricant is supplied to the pipe 30 and is maintained at a constant level therein. The oil may be thus supplied in any convenient manner, as from an inverted tank 40 mounted ina support 41 connected by a small pipe 42 to the large pipe 30. The tank 40 is open at its lower end oil is fed therefromto maintain a constant level in the pipe 30 in a manner well known in such feeding devices.

In Figs. 7 and 8, the pipe 30 is turned to such that the tubes 35 extend vertically upa posw ward, with their inner ends dipping below the surface of the oil in the pipe 30. As the pipe is then turned to the position shown in Fig. 9, each tube takes up a definite and limited quantity 'of oil and transfers it to the associated oil receptacles 12 or 20. The pipe 30 may extend continuously the full length of a twister frame, or may be made in two or more sections asseems most desirable.

It will thus appear that I have provided improved means for supplying measured quantities of oil to thereceptacles 12 or 20, and also improved means for effectively conducting a limited suppl of oil to the inner face of each twister ring 11.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed otherwise than as set forth in the claims, but what I claim is:--

1. In a twisting machine, a plurality of twister rings, oil receptacles for said rings, and means mounted on said twisting machine and effective to simultaneously supply a measured quantity of .oil toa plurality of said oil receptacles, said means portion whichis inserted in the support 41, and

comprising a pivotally mounted and partially rotatable horizontally disposed cylinder, means to move said cylinder about its pivotal axis, means to maintain oil at a predetermined level therein, and a delivery tube in said cylinder for each 011 receptacle.

2; In a twistingmachine, a plurality of twister rings, an oil receptacle for each ring, an oil con-, duit mounted on the machine, and means associated with said conduit to cause a measured quantity of oil to pass from said conduit simultaneously to each oil receptacle.
