Thus the mercury 4 tary cylindrical receiver tor a drive-transmitting upwardly discharging from the impact ring is liquid Ia, such as mercury.

A bearing 2| integrally depending communication with said outlets, extending outfrom the part II encircles and journals the upper wardly and upwardly from the receiver in an end portion of the receiver, and any access of inverted irustro-conical formation. Attachment mercury to the bearing is prevented by a sheet of the nozzles to the receiver is effected by a col metal guard sleeve 22 carried by the'part l1 and 45 iar I, embracing the receiver and welded or otherdepending toa point inthe receiver, adjacent to wise rigidly attached thereto, the nozzles being theoutlets 3. Said sleeve has the further eflect threaded into said collar, and communication of affording a body of mercury in'the receiver between the nozzles and outlets being established a stationary supporting wall so that rotation of by passages 6 in the collar individually aligned the receiver will not be materially imparted to 50 with the nozzles. V coaxially with the receiver, is a stub shaft 1 journaled in a suitable support 8, fixed beneath the apparatus.

In the absence of such sleeve, a centrifugal iorce would be so exerted on the mercury as to induce its upward travel against the receiver wall.

Preferably the valve 28 consists of a resilient, split, sheet-metal ring which is inserted under some compression in the receiver and consequently is self-expanding to maintain a sealing fit with the receiver. A vertical's'pllne "a interiorly secured-to the receiver wall engages between the ends of said ring to assure its rotation in unison with the receiver, while allowing it to freely slide upand down. The lower portion of the stem II is forked to engage opposite points of said valve, its forks a being sufficiently resilient to allow the described spring action of the valve. k

Under certain abnormal conditions of operation, mercury discharged by the nozzles 4 may fail to travel through theintended circuit effecting its return to the receiver. If, for example, the outlets 3 are open upon an initial application of power to the apparatus, the mercury discharging from the nomies will lack momentum to carryit through the 1 II, It, and 20, until rotation reaches a suitable velocity.

. such conditions mercury'will descend from the noule outlets and accumulate in the lower portion of the casing. Any such accumulation will rest upon an annular plate 32 fitted between the lower portion of the casing and the collar 5, an annular packing ring Ila being arranged beneath said plate to assure against any downward escape of mercury. -When the driven member acquires an adequate speed, such accumulation will be centrifugaily delivered to the impact ring and thence to the receiver together with the normally flowing mercury. In order that such mercury may exercise a driving effect, in its return to the receiver, the lower portion of the easing is preferably interiorly formed with a series of ribs 31, substantially coextensive with the nosales, and compelling upward and outward travel of the mercury in planes radial to the axis of the machine. w

- Power fro any desired source is applied to the driving mem r, there being illustrated an electric motor 34 effective upon the driving member through a belt II engaging a pulley It fixed on the stub shaft 1.

In the operation of the described apparatus, upon initial energization of the motor 14, the valve 29 is preferably closed. When the driving member has been brought up to a suitable speed, said valve is opened either entirely or partially.

Under depending on the amount of power which it is desired to, transmit to the driven .member.

Centrifugal force will set up a flow of mercury from the receiver outwardly through the nozzles 4, and will induce a forceful discharge of the mercury from the outer ends of the nozzles, in a direction approximately tangent to the orbit of such ends. The mounting of the nozzles is such,

Jointly determined by the adjustment of the valve 29 and by the load on the driven member.

The spent mercury in the passages I 8 and II posed by centrifugal force, since said passages are formed in a stationary portion of the apparatus.

The apparatus provides a type of drive between a driving and driven member that permits of simple, easy, and complete control of the magnitude of the power transmitted, and hence of the speed of the driven member. The drive furthermore is such that no damage may be done by sudden variations of load, suited to handling a load which is subject to considerableand sudden variations.

The invention is presented as including all such modifications and scope of the following claims.
