ENGINE OR PUMP.

appndaunn mea February 5,

Inthe U. S. Patent 1,150,430 (Ser. No. 853/581) a rotary machine is illustrated and described which is adapted to operate as an 'engineer pump and wherein a rotary and A 5 oscillatory pistonis'lformed by an intermediate disc. This disc, up to the inlet and outlet slots or ports controlled'by an annular casing, is supplemented by a sphere, the vsaid .intermediate disc being linked by l a universal joint, to two rotating spherical sectors inclined to one another and connected by the axes at the slots.

Extensive experiments with such devices have ledto the.`conclusion that, especially when the forcing or ldelivery means is a Huid, the eiiiciency 4of the device does not fulfil the requirements of practical commercial use. and this is because the spaces, shortly before the final closing of the inlet l 2 and outlet slots, are still comparatively large between the correspondingffaces of the intermediate disc and the inner faces ofthe spherical shell. The consequence is, that water, for example, to be pumped, is held back in the said spaces shortly before' the outlet slots are closedand is therefore forced with great pressure through a comparatively small orifice, thus creating losses by friction which materially reduces the efficiency. Such losses are likewise present upon the admission to the inlet opening when their opening movement commences. These disadvantages are avoided4 by this invention in which the walls of the shell mediate disc by a hollow `sphere,/a1'e s`0 -v thickened that the `spherical sectors assume t-he shape ofwedges,the.breadth of which do not exceed. .or only slightly exceed. the

width of the ports. Thus the spaces which are to be'filled or emptied,A shortly beforep Fig., 3 is a section similar to Fig. 2, the

Figs. 5 and 6 villustrate a modified construction with means for regulating the amount of Huid passing, and means for effecting reversal of the rotation when the device is used as an engine.

In the annular casing 1, which servesfor controlling the inlet and outlet ports, are

journaled shafts 2 and 3 positioned'at'an angle to one another and connected firmly to, or integral with. spherical sectors 4 and 5. The apices of these sectors `are pivoted to an intermediate disc 6, so that the latter, as soon as the spherical sectors rotate, partakes of this rotation, and also oscillates with respect to the faces of these sectors,whereby. between the disc 6 and the sectors, inlet and outlet spaces for the forcing or delivery '75 driving fluid are created. The intermediate disc 6 carries spherical shells 7 and 7', the walls of which, contrary to the known device according to the U. S. Patent hlm-1,150,430,y are materially thickened, particularly increasing towards the intermediate disc in such a way that the inner walls of the sphericalshells are, for exampie, formed by plane faces, which run parallel to the shafts 2 and 3 respectively. Corresponding-ly, the ,spherical scctors 4 and 5 are reduced to wedges j the breadthl of which transversely -to the axis does not exceed, \or only slightly exceeds. the width ofthe slots 9 and 10. These wedges are embraced by the spherical shells 90 7 kand 7', which form part of the disc 6 or rsupplement the disc 6 to constitute a full sphere withs'the exception of the slots 9 and 110. The wedges 4 and 5 are connected with 'the shafts 2 and 3 through the slots 9 and 10 95 and are shouldered at 11 and 1.2. to exactly The feeding and discharging of the driving and forcing means' is effected by pipes 13 and 14 respectively.
