IM'PROVEMENT IN ROTARY 'STEAM-NG-INES.

The Schedine referred todn these Letters Patent and making par: of the same.

To all whom it mary concern :v-

Be it known thatl, Jos F. DE NAVARRO, of the city, county, and State of N ew York, have invented aY being had tothe accompanying drawing, forming part of this specification, and in which- Figure l represents a side elevation of a rotary engine, constructed according to my improvement, with the one side cover or lid removed', "and Figure 2 a vertical section of the same through the line x x in fig. 1.

Similar letters of reference indicate corresponding parts. l This invention 'relates to a rotary engine or motor form'ed of two cylinders, one within and eccentric to the other, in combination with sliding pistons, having a radial relationship to the innercylinder, and working within and against the outer one.; said invention consisting in a combination, with said parts or devices, of one or more loose rings arranged within the inner cylinder, vand clipped by the innerV ends or portions of the sliding pistons, which are thus connected in a free or loose manner to Work in unison with each other, and in close hutfree contact with the outer cylinder.

Referring to the accompanying drawing- A represents the outer case or cylinder of the en-v dial slides or pistons.

gine, having sides 0r heads B B.

Within this cylinder A, buteccentric to it, is a cylinder, C, of a diameter to touch, or nearly so, in the course of its travel, one point or line of the inner periphery of the outer cylinder A, and carrying any snitahle number of sliding pistons, D, rwhich occupy a radial position to said inner cylinder, and pass through slots or openings in the cylinder C; also are guided at their edges by grooves made in the sides or'headsE E, to the inner cylinder C, and in or through rings or projections a c therefrom.

F is the driving-shaft, which is here represented as divided or iliade up oi' two sections fast to the heads E E of theinner cylinder G; but, if preferred, a single shaft ruiming entirely through the inner cylinder, and

if necessary, throughboth heads to the outer` cylinder A, may he used, the peculiar-construction of the engine admitting of such dispositionof the shaft.

G is the inlet, and H'the outlet orexhaust, in open communication with the outer cylinder, as indicated by dotted lines b and c.

I is a looseyring arranged within the inner cylinder C, and clipped or held in place in a ti'ee manner by the slides l), which are slotted at their inner ends for the purpose, said slides bearing'or resting, as at d d in fig. 2, on the outer periphery ot'said ring, which is free to'rotate inv concentric relationship to theouter cylinder, by the friction ofthe slides on it, along with the slides and cylinder (l In this way the several slides are connected in a direct, positive, and solid manner,l by the interposition ofthe ring'I, to move in close or steam-tight contact with the outer cylinder,

and kept self-packing, while, by'reason of -said ring being ti'ee to rotate along with the slides, wear or friction on it, or ot' the surfaces ot' the slides bearing thereon, is avoided. f

By this arrangemenaall connecting links to or from the slides, with their wear and tear, as in a loose centre-pin construction of rotary engines heretofore de- -vised or in use, are dispensed with. v

Steam, water, or any'other. 4suitable impelling-fluid may be used to operate the engine; or in the case of it being used as a pump, the shaft Ehe driven by any suitable means to rotate the'inner cylinder and its raf of the outer cylinder and concentric therewith. This -I do not claim; but

WhatfI do claim, and desire to secure by Letters Patent; is y The arrangement of the loose ring I, operating in central slots d, in the pistons D, said pistons having a radial motion in grooves on the inner sides ofthe. heads E F'of the eccentric revolving drum O, substantially as shown and described. n
