To all whom it may concern: u
' Beit known that I, Br-EON' S'rEvENs, reat Oakland, in the county of Alameda mtate of California; havev invented ceii Turbine Motors, of
a speeication. present invention relates to turbineofwhich the energy of steam or othe elastic fluid under pressure is converted -in o Vmechanical power; and 'it is an improvement upon the invention led by me in the Patent Oice September 7, 1907,

The s ecial'features involved in the present app ication are, first, a reversing device for a turbine-motor consisting of two 'sets of vanes, either of which action by means of a valve, so that the motor may be rotated in either direction; and a second feature is the compounding of two or more wheels upon the same shaft, each Wheel being of different ca acity in order that the steam may expand iiom one into the other with the greatest efiicienc and eachwheel is inclosed in a chamber by itself constituting a unit, the several chambers or units being of the same diameter and bolted to each other,
- a detail ofthe vanes, to
and inclosing the shaft.
This application also concerns a governing device the wheels -are regulated, in order that the lpro er amount of steam maybe admitted to eac The invention also relates to certain details of constructiom all of which I will nowlprocoed to describe and point out in the appended claims.
. In the drawings, which form a part'of and illustrate the invention,-Figure 1 is a sectional elevation of the compounded turbinemotor embodying my invention; Fig. 2 is an endelevation of the same; Fig. -3 is a section on line'- of Fig. 1; Fig. '4 is asectional elevation of a single wheel turbine-motor to illustrate my reversing device; and Fig. 5-is be explained.
In the drawings 1 is a base plate to support the lparts composing the compound turine-motor; 2 and 5 are standards, provided at their upper ends with bearings 1n which rotate the shaft 3, and a, b, c, d and e are units composed of the ends 6 and 11, partitions 7, 8, 9 and 10, and the rings 15, 16, 17; 18 and 19, bolted to each other at their external flanges the ends 6 and 11 are rovided with stuiling boxes 7 and `12to inc ose may be. brought into 'l by means of which the valves of all ofv solid jet of steam impinging the openings g in each set registering with' each 'other as do the partitions h, and with a central chamber forming the uid inlet.
Regulating valves il, 22, i3 and i, consisting of plain Vshort tubes, are adapted to slide into the centralspace `of each wheel across the o eningsv-g to prevent the fluid from passing t rough them a main valve is, however, located in the vinlet re resented in said application.
he valves are operated by a ball regulator f5 supported upon the standard 4, which isconnected to the valves by the ball crank lever 26 pivoted to the stand 27,.the lever being pivoted to the rod 20 which passes through the stuffing box 30 and through the walls 7, 8, 9 and 10, and is provided with the double collars 21 in the chambers a, b, c and d, between which extends the bifurcated end of the levers 22 pivotcd to the stands 23, the opposite bifurcatcd ends of which embrace the pins 25 on the valves so that the regulator f5 operates all of the valves at the same time. The regulator `receives motion from the shaft 3 from the I screw 30 into which meshes the gear 29 upon the shaft 30, provided with the bevel gear 2() which meshes with the bevel gear 27 on the regulator shaft. l n
t will bc observed that the drawings arel not strictly mechanical' but are somewhat schematic and are for illustration of the invention.
It may be known thatthe efficiency of the turbine depends largely on keeping a on the vanes, and in order that this ma be donc the nozzlel has to be designed for t 1e particular initial and terminal pressure under which it operates.
In order to carry out the invention the drawings represent four wheels of different capacity for the admission of steam which are designed for pressures of 135,78, 45 and 26 pounds per s uare inch each,` and the areas of the nozgles to correspond to the pipe 14 (not shown) as' appliany when this di be broken, and the section `shown in Fig. 3
`.6 of the previous one.
dierent volumes of the same amountv of steam at these pressures are proportionallyV .52, .90, 1.56 and 2.70, and'thecircumferences and areas of the` nozzles are proportional to these figures. M 1 i The maximum velocity of 'steam' owing in a nozzle is obtained when the lowerfpre'ssure is .6 of the up'per and does notincrease the pressure of each succeeding wheel is made But-`these are the theoretical formulae whichl may have to be changed slightly to compensate for the friction in the. passages.
` It is. proposed to design the vanes so that they will be a pontinuation ofthe nozzle, so that the solidity of the jet of steam Will not 1s drawn to represent this feature.
Referring to Figs. 4 and 5, m is a shaft terminating in the disk twithin the chamber G2., provided' with the concentric tubes n, n, in which are vanes interleaving with the concentric-tubes o, o, attached to the rear Wall r of the chamber also provided with vanes coinciding with those in the tubes n, and uis :l
'the inlet pi e in which is located the valve 'i". The va ve '115 is a section of a tube having an'in'ternal spider'y connecting with a hub upon the rod 20a, which extends through the inlet pipe a and terminates in'the yoke y2 'Within which is a cam m2 upon a'shaft w to which is pivoted a rod 20 connecting with a regulator similar to that shown in Fig. 1. The cam maybe turned in the direction of the. arrow by a lever w2 on the shaft w. In the positiony shown the valve covers the openings in one set of vanes e while the other set of vanes-, which slope in an opposite direction to those at e, are open to receive steam from the inlet pipe, which steam is regulated thereto-by the regulator or governor; and when itis desired to have the motor rotate in an opposite direction `the cam is. turned in the direction of the arrow and the valve moves to the opposite end of the chamber and closes the openings g at vthe end while uncoverin those at e. Thus a simple means is provide for reversing-the direction of the rotation of the motor at the same time the ysteam is regulated by a governor.
Fig. 5 is a section of an immovable internal tube o, and g, g are the openings between the Qva'nes h, vh which, u on their inner side are tapered to'fprin a be l mouth to the openings, or the openings are divergent toward the intake, in order that a solid )et of steam may be .delivered to the succeeding vanes beyond,
as it is Well known that amore solid ]et of fluid can be passed through an orifice if the intake is divergent.
