DRILLING ll/lIACI-IINIE.
Application filed February having an opening through which the drill The stationary slip stem loosely extends. ring of the bed is in addition to the movable slip ring, carried by the rotary. 1th this arrangement, when drilling or when removing the drill pipe any obgects that might fall or be dropped will be caught bythe safety ring. The safety ring permits the couplings on the drill stem to pass therethrough but when the drill b1t engages the safety ring the safety ring is lifted out of the stationary slip ring and up through the movable slip ring mounted on the rotary.
Other objects and advantages residein' certain novel features of the construction, arrangement and comblnation of parts which will be hereinafter more fully described and particularly pointed out in the appended claims, reference being had to the accompanying drawing forming a part of this specification, and in which: Figure 1 is a view partly in section and 33 partly in elevation showing the present invention embodied in a rotary,
Figure 2 is a' perspective view of the stationary slip ring, and s Figure 3 is a perspective view of the safety ring.
Referring to the drawings the numeral 1 designates generally a rotary which may be of any standard or conventional type, and which has a stationary bed 2 on which the rotating frame 8 is mounted. The rotating frame or part 3 carries a slip ring t in accordance with the usual practice.
The present invention proposes the provision of a bottom slip ring arrangement which includes a stationary slip ring 5 secured to the stationary bed 2 of the rotary in any suitable manner and having an inner in carrying out the present invention, the

removable stationary ring 6. The inner face of the outer ring5 is inclined as indicated at 7 and the outer periphery of the inner ringG is similarly inclined, so that when the inner ring 6 is dropped into the outer ring 5, it Wlll be engaged therewith and supported thereby, as shown in Figure 1. The inner ring 6 has an inwardlydirect-ed annular flange 8'around its lower edge which provides a supporting shelf for an annular safety ring 9. The safety ring 9 is flatyn I has its outer periphery resting on t shelf providedby the flange 8. Genand trally this ring 9 has an openinglO designed to loosely receive the drill steniS and its coupling. lVith this arrangement, should an object be dropped or falldown through the ring tit will be supported by the safety ring 9 during the drilling operation as well a as when removing the drill stem. jlVhen the drill-b t engages under the safety ring 9 it lifts the safety ring 9 up through therotary/ These advantages are had and no interference is presented to the normal drilling operation which is carried out in. ac
cordanee with the conventional practice.
1- cla1m: 1. A rotary having the usual slip ring mounted on the rotating part thereof and also having a bed provided with a slip ring arrangement including an outerring fixed to the bed and an inner ring carried within the outer ring and provided with an inturned annular flange presenting a shelf, and a safety ring mounted on 'saidshelf and having an opening througlrwhich the drill stem and its couplings loosely pass, the safety ring being designed toprevent objects from falling or dropping down into the well when drilling or when removing the drill stem.
2. A rotary having the usual slip ring mounted on the rotating part thereof and also having a stationary bed, an inturned shelf supported'on the stationary bed and a safety ring mounted on said shelf and hav ing an opening through which the drill stem and its couplings loosely pass, the safety ring being designed to prevent obstructions from falling or dropping into the well when drilling or when removing the drill stem.
