Application filed August 20. 1906. Serial No. 331.273.
Be it known that we, JOHN G. CALLAN and HENRY J. HANZLIK, citizens of the United States, residing, respectively, at Lynn, county of Essex, State of Massachusetts, have invented certain new and useful Improvements in Elastic-Fluid Turbines, of which the following is aspecification.
This invention relates to engines driven by an elastic Huid, such as steam, and has especial reference to steam-turbines of the horif blocks 2 3,
The object of the invention is to facilitate the removal of the u per half of the casing without disturbing t e piping in order to give ready access to the packing and other internal parts.
Furthermore, it aims to locate the valvegear in a position Where it will not be eX- posed to dirt or injury and yet will be entirely accessible.
Incidentally it strives to produce a design which gives a neat and attractive appear-l ance.
To this end the invention consists in a construction wherein the valve-gear is located in the lower lpart of a illow-block, and the nozzles and nozzle-,va ves are arranged in 'the lower half of the turbine, thecasing being divided in two on a horizontal line and the pipin being connected with the lower half.
n the accompanying drawing, Figure lis a side elevation of a orizontal ysteam-pr- 1g.
the oil-pump on a larger scale. Fig. 4 is an end view of said pump, partlyin section; and Fig. 5 is a longitudinal vertical' section on the line55,Fig.2. v
The' bed-plate 1 is 'referably a hollow casting, `and to-it .are astened the pillowin which is journaled the horizontal shaft 4. The bucket-wheels 5 are secured to said shaft and carry atwo or more rows of.
buckets 6, coperating rows of intermediates 7. to said buckets through nozzles 8, opening from a steam-chest 9, each valve'being'conwith one Aor more trolled by itsl valve 1 0. 'The'.bucket-wheela' weight l5 ,each of which operates a hoo adapted' to engage with a slide .Steam is supplied l are inclosed in a casing 11, which iscomposed of two parts meeting on a preferably horizontal diametrical plane. The casing is preferably cylindrical, or substantially so, yand has suitable heads 12. Suitable packing surrounds the shaft at the point where it `passes through said heads. The steam-chest 9 is preferably integral with one head, being'lo cated in the lowerhalf thereof below the shaft. The steam-main 13 connects with the upper part of said steam-chest and is controlled by a throttle-valve 14,' which can be opened and closed either by a hand-wheel 15 or automat- -ically, as by release and fall of weight 15. position of the' steam-main brings` The low this hand-wheel within easy reach ofthe engineer. The valve is preferably provided with an emergency mechanism of some aproved type for closing it automatically-as, j or example, by releasing the aforesaid The stems 18 of the nozzle-valves 10 open through stuffing-boxes 19 in the cover 20l ofthe steam-chest and extend across the space lbetween said chest and thepillow-block 3, into the. lower part of which they enter.
Suitable mechanism for operating the valvestems is housed inthe hollow pillow-block below the shaft-bearing. In the' drawings we `have indicated mechanism 'similar vto'that `shown in the ending application of JohnG. Callan, Seria transverse shaft 21, carryin eccentricsv22,
-'bar or dog23,
with Valve-stem, By means of this' mech- 1n case the engine attains anex- 'cesslve speed. This mechanism may con- 24, connected No. 276,656.5, comprising a f tails form no part of the present invention,)
the nozzle -galves are Iopened 4'and closed in- .'vice 25, mounted on the end of the shaft andI anism, (which is ynot fully shown, as its `deconnected with thevalve-controlling mechanism by a rod 26, lever 27, link 28, and crank 29. There is ample room inside the pillow-block for a Valve-gear of the type here used, and at the same time the arrangement utilizes for the gear space already .necessarily usedby the pillow-block. The gear is entirely unobtrusive and is securely protected from y dust and dirt and mechanical injury. It is easy of access' for oiling and in operation and repair through openings in the front and sides of the pillow-block closed by the cover 30 and doors 31.
Lubricant is supplied to the bearings of the machine by an oil-pump mountedV on the pillow-block andcomprising two geared rotary elements 32 33, driven by the shaft 21 and delivering oil or other lubricant through a conduit, which is provided with arelief or bypass valve 34, loaded with a spring 35, which can be adjusted from outside the casing by a stem 36.
- At some suitable point on the casingvwe locate `a stage-valve 37. In case the secondstage nozzles are located in the upper haii` of the shell this entails placing the stage-valve in this half also,'as illustrated in the drawings, though it is evident that if the second-stave nozzles are arranged in the lower half t .e stage-valve will be correspondingly shited. When placed in the upper half, a small, pipe 38 will be run to it, and this necessitates making said pipe in two lengths, coupled by a union 39 st about the height of the split in the shell, so that said pipe may be readily broken when the upper half of the shell is to be removed. It will be notedthat this is the only steam connection that has to be dis-` turbed when the shell is to be opened. The
4o invention therefore provides for the ready ins ectionof the parts by the easy removal of tlie upper half of the shell, protects the valvegear from dirt and injury by housing it in the otherwise useless space inside the pillowblock, brings said gear andthe throttlevalve down Within-convenient reach of the operator, and enhances theA attractive appearance ofthe machine. y
In accordance with the provisions of the 5o patent statutes we have described the principle of operationof our invention, together wlth the apparatus which we now consider to represent the best embodiment thereof; but We desire to have it understood. that the apparatus shown is only illustrative and that the invention can be 'carried out by other What we claim as new, and desire to secure by Letters'Patent ofthe United States, is 1-.
