Application filed October 12, 1905. Serial No. 282,518.

To all whom it may concern:

Be it known that 1, MICHAEL J. Solomon", a -citizen of the llnited States, residing at Dover, in the county of Kent and State of Delaware, have invented new and useful improvements in Impulse-Turbines, of which the following is a specification.

This invention relates to impulse turbines, and the primary object of the same is to provide a turbine of this class having a superior operation and provided with means whereby the motive fluid is thrown out from the center by the rotation of an impulse drum against motion augmenting devices connected up to the shaft of the drum and operated by the motive fluid thrown out towards the periphery of the drum, the turbine operating as a source of power for driving mechanisms of various forms.

it further object of the invention is to provide an impulse turbine having a compara tively simple construction and etlective operation and of a strong and durable nature.

in the drawings: Figure 1 is a side elevation, partially in section, of a turbine embodying the features of the invention. Fig. 2 is a top plan view of the impulse drum.

Similar characters of reference are cur ployed to indicate corresponding parts in the views.

The numeral 1 designates the impulse drumprovided with a central chamber having curvilinearwalls 3 and 4 which are braced and held in adjusted position by radially arranged bars 5 extending outwardly to the periphery of the drum. The chamber has a closed top 2" and a bottom 2" also closed except where a depending teed-sue tion pipe 6 communicates therewith at the center, the said pipe being open and connecting at its lower extremity with a suitable motive fluid supply. The impulse drum 1' is rotatably supported within a frame 7 through the medium of a vertically extending shaft 8 mounted at its lower end in a bearing 9 carried by the closed bottom of the said frame 7, the shaft at its upper extremity within the frame 7 being provided with a beveled gear 11 fixed to the top of the said frame. The upper end of the shaft projecting through the top oi the frame 7 has a hand pulley 12 fixed thereon from which motion may be. transmitted to mechanism to be driven. The drum 1 hetwcen the peripheral wall thereof and the walls 3 and 4 is hollow at 13 and 1 1, and open at the bottom as shown by Fig.

1; and arranged atoppostte ends of the hollow spaces 13 and 1 1 are vertically extending shafts 1:3 and 16 supported at their lower ends upon brackets 17 radially projecting outwardly from the bottom 2" of the chamber 2, the shafts 15 and 16 at their upper ends extending through horizontal arms of brackets 18 and carrying beveled pinions 19, the latter being held in continual mesh with gears 20 fixed on the opposite ends of a horizontal or counter-shaft 21 having bearings at opposite extremities in vertical members of the said brackets 18. The shaft 21 also car ries a beveled pinion 22 held in continual mesh with the pinion 11 fixed to the top 10 of the frame 7.

The bottom portions of the hollow spaces 13 and 1e are fully open so that the motive fluid contents thereof may fall into a fixed collecting receptacle 29' held on. the bottom of the frame 7 and having a train of outlet pipes 29. Each of the shafts 15 and 16 car ries'an impulse wheel 23 horizontally disposed and having outwardly projecting blades, each of the said impulse wheels being disposed in operative relation with respect to a nozzle 24 located at the ends of the chambers 13 and 14: adjacent to-the said impulse wheels. These nozzles are in opposed positions in their respective spaces 13 and 14,

the said spaces constituting outlet chambers for the relief of the chamber 2, the communication between the latter chamber and the, spaces or outlet chambers 13 and 11 being etl'ected through the nozzles. :21. Two impact wheels, one on each shaft 15 and 16, are shown to demonstrate a practical-apparatus, but it will be understood that the number of these wheels may be increased and the number of nozzles correspondingly multiplied.

Secured on the bottom of the frame 7 is a slotting-box 25 for the lower end of the motive fluid supply pipe 6, the stuliing-box surroundin the bearing 9 at the lower end of the shat. Connected to the bottom of the frame 7, as at 26, is a cut-oil 27 consisting of suitable valve, and communicating therewith is a motive fiuid supply pipe 28. It will be understood that when the cut-off 2T opened the motive fluid may pass from the pipe 28 upwardly through the stuffingbox the latter being tul'ailar or hollow, into the reed pipe 6. When the cut-oil is closed, the supply o'l' motive fluid to the turbine will be interrupted, as will be appreciated.

operation of the turbine-as shown by through the nozzles 24 Figs. 1 and 2 is as follows: The motive fluid passing into the chamber 2 will be thrown out andact upon the curvilinear Walls 3 and 4 and be directed by the latter in reverse directions towards the nozzles 2e,

and the discharge of the fluid through the nozzles will efiiecta rotation of the impulse drum 1 after the manner of the operation of a Herosfountain, and the fluid passing through the nozzles 24 will be clirecteii against the impulse wheels 23, thus breaking up the fluid current 01'- foroeox the fluid and preventing obstructive action of said; fluid that might ensue if it was permittetl' to pass Itwill be observed that the incoming motive fluid under pressure has but two outlets from the chamber 2, namely through the nozzles 24, and. as these nozzles are mate rially reduced ascompared to the capacity of the chamherii, the force of the fluid escapingthrough the nozzles will set up sutiicient momentum with relation to the impulse drum 1 to rotate the shaft with consitierahle power. A uniformity of rotation of the impulse Wheels 23 is maintaineilh y ii1- tergearing the said Wheels with the shaft 21 and the pinion 11 as hereinbefesfe e2:- glained, and the motive fluid after having een deprived of its force falls into the c0ieoeese lasting receptacle 29* and escapes through the pipe 29, r

It will be evident from theforegoing construction that the shaft 8 can be operated with power'advantageswhich "will he de-- pendent upon the initial force orpressure of the motive fluid entering theturhine.

Having thus described the invention, What is claimed asnew, is: v v

An impulse turbine comprising an inclosing frame, a shaft extendingtherethrough and rotatable therein, an impulse Chaim fixed or the shaft and. provided with a. central receptaclelbelow the drum and. its outlet chambers, gearing for renderihg the operation otthe impulse Wheels unitorimotner gear devices for transmit ing the motion of said gearing to the firemanctineans tor controlling" the supply of a motive tluicl to the drum.

In testimony whei'eof I have hereunto set 7 my hand in presence of two subscribing witnesses. V c MICHAEL Jfi-GANLG-lil viiitness'esy e EDWAR JL Soaivhoiq Josseti H. Dmzma if,
