'A ring or hoop m, has itslo'wei' portion provided with a shoulder m1 on which rests the lower surface of the flange h2 when theI y apparatus is not working and the tool car-` rier is arranged vertically, the piirt "h3 pointing downward. l f The annular part a2 has threadedengagement, as at as with the rim z", as seen in I Fig. 1. A. ring a `is disposed in a screwthreaded annular recess in the upper ortion of the riiii m, as seen in Fig. l, a smal screw a",-as shown in said ligure, being provided above said member ai'. This ring formsy a tight joint at this point.

A ball bearing n is situated at the lower extremity o the shaft f and its inner part is held in position Ly a late n1 and a screw n2, the outer portion o said bearing being held in a corresponding recess of the part It. A ball bearing o similar to the preceding one is situated at the upper end of the shaft f and the inner portion of this is held be tween two sleeves o1, o2 integral with the said shaft f; the outer portion of this bear ing rests on top of the ackings 7J of the stalling box b1 and is hel in acorrespond.

fitted to the shaft. f end having a feedihg channel r1 inl a boss r2 which in the example shown is in tegral with hood g and prevents any leakage of the lubricant in whatever position the tool carrier is held.

The fitting together of all these .parts is exceedingly simple. The shaft f` is turned upside down sov that the end to which the piriion i is fitted is on top and then the cheeks lc, the shafts j and the satellites 3 and z" are pushed oii to the shaft'f then tho lower ball bearing lc, the ball bea-ra ing n, the plate nl, and the screw n'-i are fitted in tieir respective positions and kthen the shaft f is turned back into its normal position. The upper ball bear- I' ing li:2 is then fitted andthe part f/ placed above it, then the key f is placed in the corresponding rroove of the shaft. f and then the parts e f", 6", e, f, b, e', f', b-, e, b, 0*,p. o and o* are successively placed in position on the shaft. f, the last mentioned part (oz) beine'v keyed ir otherwise firmly ixeelthereon, then the washer q2 is slid on the shaft and the winged part r is arranged above it. The cap g is then screwed up tight; l The shaft f togetherwith all the parts just referred to can be slid as a. whole from the bottom to the top into the casing a where the shaft is lixed iii. position n by screwing the part y into the .screw thread a* and when this has been etlecledthe. whole is turned back again, then the ball bearing l is placed in position as well asthc arrange;k

ment formed by the parts/i. and the rini 3, y*

which is then capped by the partgm, which is screwed on to the screw thread u?. By i manipulation of the handle c, the actuating iiiedniin is admitted to thechaniber from which it isledrto the distributors which are thereby caused to revolve and by incaiis of the differential gear the actual tool carrier is rotated at a considerably reduced speed. 0f course, the various parts may be made of any `suitable met-.d but aluminum will preferably be used for all the various .parts y except the gear wheels and their shafts, the blade wheels, the main shaft and its fittings and ball bearings.. n A

The invention is by no means limited to the single kform of construction just described, butl comprises on the coiitrar any' modifications, such as those for example in which the ditferential gear is substituted by another systein as by a gear for increasing,

the speed instead of a reducing gear as has bec'i shown in the present example, or the number of expansion steps ma be other than four, or a radial or reaction turbine medium more particularly if compressed air is used, may be eti'ected through the axis of the whole arrangement so as to utilizo this duid for coolin 1, the tool. Neither is the invention limite with respect to the s ecial arrangement of the above mentioned ubrivemployed, or the exhaust, of the actuatingk y ioo l cator, to the appiication of tliissa id aiaiigeV f rient to the upper lubricator of tool carriers ot' the present system but includes the applicationof the said arrangement toall lubrif cators. Having thus described iiiy 4invention what l claim is:

1. A. tool of the class described, comprising a cylindrical casing, n series of distributers superiin posed, the lower one having an annular riin having radial ports, bladeA wheels arranged between said distributors, a shaft, and adillcrential gear in l'aid casing, said blade wheels being spliiieu to said shaft.

2.- A tool of the class described, compriscasing, said blade wheels being splined to` said shaft, and a winged lubricator carried by said shaft.

3. A tool of the class described, coinprisin n. cylindrical casing, 'a seriesA of distri nteis superimposed, the lower one having an annular rnnyhaving radial ports,`
