My invention` comprises, more` specically, a The periphery of the 1base washer 'I is provided waxer ofthe abovecharacter in whicha suitable witha flaring skirt orange I4 having at one 50 support is provided with an uprising pin on ywhich point thereon a weighted p ojection I5 oi' hard- .the uprising hub of the rotary base washer is tenedor wear resisting material, which projection `loosely hung for limitedlateral movement, the unbalances the base washer sufliciently to cause basewasher being weighted on its periphery, as, it, by centrifugal action, to bring the projecfor instance, by` a `hardened orv wear resisting tion I5into 'Contact with the side wall 5 of the 55 support when the rotative speed of the washer rises to a predetermined point. This contacting of the projection I5 with the side wall 5 causes the rotative speed of the washer to be automatically reduced to a safe limit.

The washer supporting pin 6 may be adjusted laterally to and secured in different positions with respect to the side wall 5 of the support so as to increase or diminish the normal space between the washer and the said side wall, to suit diierent yarn and speed conditions as will be hereinafter more fully explained. This lateral adjustment of the pin and thereby the washer suspended therefrom is accomplished by providing the pin with a threaded portion I6 which extends through a hole I1 in the crossbar 3, which hole is considerably larger in diameter than the diameter of the said threaded portion I6. Lock nuts I8 and I9 are threaded on the portion I B above and below the crossbar 3, which nuts may be tightened to secure the pin in its lateral adjustment with respect to the side wall 5 of the support.

As the yarn passes from the tension device to and through the waxer to the package being wound, the yarn will rotate the washer and the wax cake carried thereby. When the washer rises to a predetermined speed the weighted projection I5 will, because of centrifugal force on the unbalanced washer, be brought into contact with the side wail 5 of the support to automatically retard the washer.

The reason for the lateral adjustment of the pin 6 is to increase or decrease the normal space between the weighted projection on the eccentrically weighted washer and the side wall of the support. This will allow a greater or lesser degree of impact when the weighted projection hits the side wall as the washer rises to a predetermined speed. When the upright pin B is permanently set, the centrifugally rotated washer and the side wall, constituting the speed controlling mechanism, automatically compensate for different speeds of yarn.

From the above description it will be seen that I have produced a waxer having automatic centrifugally controlled means for retarding to a greater or lesser extent the free rotation of the washer and its wax cake to suit different requirements as hereinabove pointed out, and it will also be seen that I have produced a waxing device which may be adjusted' to suit different yarn and speed conditions.

It is evident that various changes may be resorted to in the construction, form and arrangement of the several parts without departing from the spirit and scope of my invention, and hence I do not intend to be limited to the particular embodiment herein shown and described, but

What I claim is:

1. In a yarn waxer, a support, a rotary eccentrically weighted washer and a wax cake carried thereby, the weighted side of the said washer being arranged, by centrifugal action, to be brought into contact with the support for automatically retarding the washer.

2.

In a yarn waxer, an uprising pin, a rotary washer having an uprising hub loosely hung on said pin and a wax cake carried by the washer, said washer being arranged, by centrifugal action, to be brought into contact with the support for automatically retarding the washer, and means for laterally adjusting the pin and thereby the washer to suit diierent yarn and speed conditions.

7. In a yarn waxer, a support, a rotary washer and a wax cake carried thereby, said washer having centrifugally controlled means arranged to contact with the support for automatically retarding the washer when it rises to a predetermined speed.

8. In a yarn waxer, a support, a rotary washer and a wax cake carried thereby, said washer having centrifugally controlledmeans arranged to contact with the support for automatically retarding the washer when it rises to a predetermined speed, and means for laterally adjusting the position of the washer to suit diiferent yarn and speed conditions.

9. In a yarn waxer, a support, an uprising pin, a rotary washer loosely hung thereon and a wax cake carried by the washer, said washer having centrifugally controlled means arranged to contact with the support for automatically retarding the washer when it rises to a predetermined speed.

10. In a yarn waxer, a support, an uprising pin, a rotary washer loosely hung thereon and a wax cake carried by the washer, said washer having centrifugally controlled means arranged to contact with the support for automatically retarding the washer when it rises to a predetermined speed, and means for laterally adjusting the pin and thereby the washer to suit yarn and speed conditions.

11. In a yarn waxer, a support,- an uprising pin, a rotary washer having a hub loosely hung on said pin and a wax cake carried by the washer, said washer having centritugally controlled means arranged to contact withv the support for automatically retarding the washer when it rises to a predetermined speed.
