In the construction of lifting apparatus Fig. 3,

an outer receptacle 3 of less depth surrounds the inner, or said receptacle 3 of Fig. 1, andcross bars or braces l9 connected to said drive shaft I extend outward flush over saidrim I of' said inner receptacle 3, a second or lower air expeller l3 consisting of an annularv disk plate 5 andblades 6 connected tosaid cross bars or arms [9, cross' bars 1 connected by braces Zi'Lto said lower air expeller 13 with globelets 8 hinged to said cross 5 bars I by said flexible cable 95 in this construction said drive shaft I, supper disk plate Sand blades 6 making up the said upper air expeller I 3, cross bars or arms. i9, annular disk plate5 4 and blades 6 making up said lower 'air expeller 9!. l3, and braces 26, cross'bars 1, lobelets 8, cable 9, all these makeup as'a whole or as one-unit the apparatus rotatable body; it will be apparent thatin this construction the air expelled by the said upper air expeller l3 and bridging said gap lBof said inner receptacle 3 enters the'path of blades 6 of said lower air expeller l3.with energy retained, and further'on errtering'the field of I'D-1 tation of said lowerair expeller/encounters less resistance, causing'a more effective bridging of, ';S&ld gap l6 of said inner receptacle 3, and caus ingithe air expelled byrsaid' lower air expeller to.

effectively also; thus it will be seen that when carrying the construction of said lifting appara-' tusinto multiplicity that thereby the energy units imparted will be more fullyfconverted into lifting force. Y a 1 In construction of lifting apparatus:Fig. 5,.said receptacle 3 is fashioned bowl' like and is keyed Q solidly to said drive shaft l "and becomes part of the said rotatable body; when this lifting apparatus rotates so that said gap IB'is bridged by air from said air expeller 13, the air ;contained in i said bowl shaped receptacle 3, and the air leak inginto it after first exhaustion, is centrifugally forced to said rim I 8 to augment and be carried, over said rim 8 by the air from air expeller L3;

in the former constructionswith their stationary 1 receptacle 3, said air is expelled in like manner, being set in rotation by said rotating air blanket bridging gap l6, by pull of its own weight outward; were it not for the advantages here depicted, a plate inside of said upper rim $8 of receptacle 3 would serve equally as well; when also applying blades 6 to the lower surface of air expeller l3, it was found that said blades would not expedite or increase the low pressure in receptacle 3, which said low-pressure is entirely determined by the velocity of the air passing over said gap it.

.:Having thus described my invention, it being understood that appropriate changes may be resorted to in its construction without departing to said drive shaft, blades bolted or attached to, the upper surface of said disk plate and radiating from its center and which constitute said apparatus air expeller, cross bars or arms attached to said drive shaft, afiexible intermediate connecting member attached to said'cross bars or arms, hollow globeletsor balls attached tosaid intermediate member, a stationary receptacle with a closed bottom and an open top compri's-' ing the stationarybase of said lifting or propulsion apparatus, a bearing in the said closed bottom of said stationaryreceptacle'or base fitted through which operates'said drive shaft or said rotatable body, braces fitted to the said stationcontrol air inlet 'pipe'with a control valve connected to the said bottom of said stationary receptacle or base, and the whole operating in a manner creating by a flowing and rotating body of air over a gap of said lifting or propulsion apparatus a low pressure on an area on the upper surface thereof and retaining the full static at-- mospheric pressure on the lower side; thereof intact as its lifting force. a 7
