Application led September 24, 1910..- Serial No. 583,587, I

Be it-known that I, EMANUEL FISHER, J r., a citizen of the United States, residing at the city of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Engines, of which the following 1s a specification, .reference being had therein to the accompanying drawing.

This vinvention relates to engines particularly of `the `rotary type known as turbine engines, and a special object of the invention is to provide an engine of this vcharacter i scribed and part i bedr' which is adapted to be driven or actuated by any suitable iuid under pressure whether steam or other gases produced by volatilization or by the explosion of a combustible mixture.

With these and other objects in view, the invention consists` of certain novel features of construction, as Vwill be more fully "deicularly pointed out in the appended claims.-

In lthe accompanying drawings: Figure l-represents a substantially vertical section through an engine constructed according to my invention. Fig. 2-represents a section `on line 2--2 of Fig. 1. Fig. 3-represents a section on line 3 -3of Fig. 1 but on a larger scale, the crank shaft which is mounted in one end of the main shaft being omitted. Fig. Ll-is a side elevation of so much of the .engine as is' necessary to illustrate its use with steam as the motive iuid. Fig. 5-is asection representing a doubled construction of thegwheel and showing a structure whereby the ,Huid is controlled in its passage to the-wheel." ,In fact Fig. 5 illustrates a preferred structure, Fig. lillustrating simply. more of the details of the structure embraced inA Fig. 5.. Fig. 6-'is a detail view of' anism.

part of the valve controlling mecha- Similar referencecharacters indicate the same or similar parts in all ofthe views.

Referring first to Figs. v1, 2 and 3,' the 10 of the casing is provided with a removable side plate 11 foi-.the urpose ofassembling the casing and the w eel presently v described. The shaft 12,(passesthrough a suitable stuiiingbox carrie bythe side plate l 11 and at its inner end is mounted in the body of the casing. Keyed on the shaft 12;

-.ggiisragrwheel '13 having a series of concentric portions,` which, for convenience. of description but without .intention lofbeing limited concentric rings.

thereby will be hereinafter referred to as' The inner or first ring 14 might be considered as the hub of the wheel `which isl jso keyed on the shaft. The second ring is in'- dlcated at 15, the third ring at 16, and a fourth or A'outer ring is indicated at 17.

There may be a greater or lesser number of Y these rings. Concentric vring shaped portions of the casing, or ring shaped members of the ring 14, the inner surface of the ring Y 17', and both the 'inner and outtr surfaces of all of t-he intermediate concentric rings or .members, are formed with suitable pockets as by corrugating said surfaces. By corrugated surfaces I mean to include any surface provided with teeth or blades or ridges and grooves against which the motive Huid may l impinge for the purpdse of actuating the rotating member.

' A chamber 21 for motive fluid under pressure is connected by ports 22 with a plural- I ity of chambers 23 inthe ring 18. Similar chambers 23 are formed in the other ring members of the casing, and each ofsaid chambers 23 is connected with the annular spaces orvcrevices between the coperating rings by jet openings 24 so that motive fluid issuing from the chamber 23 through said the pockets or -corrugations formed in the ring members of the wheel to rotate `the latter. Alternating with the chambers 23 are exhaust/chambers 25 into which the motive iuid may escape, after act-ing as described, suitable openings for such escape being indicated at 26. Each exhaust chamber 25 is connected by ports 27 in the casing with the next pressure chamber 2 3 in the succeeding outer ring membervof the casing. The peripheral portion of the' casing is shown as provided with 'long exhaust chambers 28 the exhaust chambers 25 in the ring member vmunica e with openings 29 in the casing, in

jet opening 24 will act against the walls ,ofv

which connect through suitable ports with' of the c ing, and said chambers 28 com' .which" openings suitable exhaust pipes may ybe secured.

The casing as showf inl Fig-.,512 isformed with a lcrank and gear chamber 30, and with cylin'ders 31 surrounding, and radial to, said chamber 30. Pistons 32 are mounted in said cylinders.

A crank shaft 33 is rotatively mounted in a suitable ball bearing therefor in the end portion of the shaft 12, the outer end of said crank shaftv being supported by a bearing in a cap plate 34 which covers the chamber 30. 'Mounted on the'opposite or crank ortion of the crank 33 are disks 35, said disks being connected by pins 37. A pitman 36 connects each pin 37 with a piston 32. The endof shaft 12 is toothed or .proyided with a rigidpinion 38, and adjacent'thereto, and

keyed on the crank shaft 33, is a gear. 39. One or more compound gears and plnions '41 mounted on studs 40 projecting into the chamber 30 from the body of the casing, mesh ,with the pinion' and gear 38-39 in such manner that, as the shaft 12 rotates, the crank shaft 33 will be rotated at a considera'ble reduced speed, which speed may be in the ratio of six to one. Such rotation causes the pistons to be actuated in succession, for the purpose presently described.

A carbureter of any suitable or preferable construction is indicated conventlonally at 42, the combustible mixture therefrom leading to an annular chamber 43, said chamber having an opening controlled by an inwardly opening valve 44 for each cylinder behind the piston. An outlet from each cylinder, controlled by a spring regulated valve 45, connects with the chamber 21, in which chamber sparker points 46 may be located, so that any suitable igniting device may be employed to periodically explode the mixture which is compressed into the chamber ,21 by the action of the 'series of pistons described.

The casing may be formed with suitable chambers 47 for water cooling purposes, the circulation of water being provided for by means of suitable pipes 48 and connections.

lt will now be understoodV that, with the structure illustrated in Figs. 1, 2 and 3, an explosive mixture is first compressed into an explosion chamber and there ignited, the pressure resulting from the continuous series of explosions being transmitted successively through the ports 22 and into the chambers 23 and from thence throughv jet openings 24 and thencesuccessively through similar chambers and through ports and through exhaust chambers so as to successively act upon the concentric rings of the impact wheel. In the structure sol far ydescribed, no valves have been referred to eX- cepting those which co-act with the pistons for drawing in and compressing the eXplosivef mixture. But l prefer however to employ a valve structure which will be hereinafter described in connection with Fig. 5.

Before referring to that structure however,

reference will first be made toFig. 4 which is intended to indicate the same general form of alternately fixed and rotating members to secure'power from the impact of the" the steam would pass so as to act upon the" successive rings of the engine 1n the manner hereiiibefore described, said steaml finally exhausting through a pipe 52. To control the supply of the steam as the motive Huid, I may employ an ordinary governor vthe weight 53 of which will act upon the stemA 54 of the usual type of governor valve for cont-rolling the supply of steam through pipe 51. lThe governor may be actuated by a belt 55 driven by a pulley on a reduced portion 56 of the shaft 12. In said Fig. 4 l have indicated a pulley 57 by means of which power maybe conveyed to the machinery to be driven by the engine. Of course a similar pulley, or other power transmit-ting device or devices would be employed in every case.

lReferring' to Figs. 5 and 6, the casing l0 Y is shown as having ring members projecting from two opposite inner walls. That is, it doubles the structure shown in Fig. 1. The wheel is shown as provided with ring members projecting in opposite directions from a central web'and coperating with the ring members of the casing in the same manner as has been already described, the same reference characters being employed in Fig. 5 as in Fig. 1, where nthe, structures are the same or substantially the same. ln this double structure the outer exhaust chamber 280 connects with an exhaust pipe 290.. The port 22 communicates with an annular cham. ber 61 formed in the casing, said chamber communicating by means of ports 62 with a longitudinal passage 63 in the shaft v12.l

of. Said sleeve is formed with apertures 66.

(see Fig. 6) preferably tapered so that longitudinal shifting of the sleeve 65 will gradually control the escape of the motive .fluid from ports 65, so as to permit more or less of said fluid to pass on through ports 67 and to the chambers 23. This valve sleeve 65 may be controlled as to its position by means of a' governor 68 rotatively actuated by means of bevel gearing 69 and a belt 70 running from the shaft 12 over a pulley on the shaft 71 of said bevel gearing. The vertical moving member 72 of the governor is connected to a bell crank lever 73, the latter engaging between collars 74 of sleeve 65. It will now be understood that, when the engine is running, the governor 68 will control the supply of motive fluid by means of the .valve sleeve 65. 1
