TUBBINE. e

Application` filed November 12, 1925. Serial No. 68,632.

- To all whom t mayv concern.'

Beit known that I, WILLIAM A. MonToN, a citizen ot' the United States, residing at Los Angeles, in the county of Los Angeles and State of California,'have invented/new and useful Improvements -in rl'urbines, ot which the following is a specification.

My invention is a turbine, particularly adapted for use in driving tools in well boring, or as al rotary hand tool for driving various portable tools. i

An object of my invention is to torni a turbine which may be driven bya liquid or compressed gas, such as water, airor steam and to io-rin a mounting for the turbine so that it may be located at the ybottom ot well piping or a well boring rodto utilize the tur.- bine to drive various types oi well drilling and boring tools having arotary action.

A further feature of my invention is a turbine base forming a housing for the` turbine, the base having a screw threaded rim in which a packing cap may be attached and the ypacking cap having an eduction plate also forming a `iournal and havingl eduction passages for the discharged liquid or gas used in the turbine. Y

Mv invention will be more read-ily understood from the following 'description and drawings, in which;

Figure 1 is a sideV elevation of the turbine showing the manner in which it is complete ly yenclosed with the eduction plate illustrated by a broken section.'

Fig. 2 is a vert'cal section of Fig. 1, on the line 2 2 in the direction of the arrows, showing the turbine housing, the turbine, a packing cap forming a closure for the li'ournal housing and a journal for the turbine sha'ft and an eduction plate. also forining` aI journal.

Fig. 3 is a. horizontal section on the line 3 3 of Fig. 2, in the direction of the arrows, indica-ting the flow passages in the turbine housing and the-turbine.

Fig. l is a horizontal section of Fig. 2, on the line 4 4 vin the direction of the arrows. y

Fig. 5 is an end View et` the turbine rotor as it taken in the direction of the arrow 5 ot Fig. 6.

Fig. 6' is rotor in the Fig. 5.

Referring particularly to Figs. l and 2, a .turbine housing `l is preferaloly formed a side elevation of the'k turbine direction of the arrow 6v of with a standard tapered upper end 2 adapt- .ed to connect to a-well boring rod 3 in the form of a pipe. VThe housing has a vcentral bored passage lffor the compressed gas or liquid being used. A diagonal ypassage 5 connects with the passage 4c and is closed at the outer end byv a plug. 'A turbine chamberV 7 is formed in the base of the housing tor tlie'turbine andl a recess 8 `for a thrust bearing as hereafter described.y An inlet duct 9 leads from the passage 5 to the turbine chamber 7 and an outlet ductlO'is formed on the opposite side of the housing from the duct 9 for the waste fluids. c,

A rim 11 on the lower'- edge of.v the housing is internally screwl threaded and receives a packing cap 12, this having a reducedy upper ,endy 13 hav-ing a screw threaded engagement with the rim 11. This packing cap has an internal socket 14, and"VV an annular deep Groove 'p15` with a discharge duct 16 leading from the. outlet duct to the annular groove l5. n

A skirt. 17 depends from the packing cap and has an internally screw threaded poraway` thefluid used by the turbine.

The turbine rotor is illustrated.particularlyin Figs. 2, 3 and 5 and is designated generally bythe numeral 21,' having a. hub 22 with vanes 23 extending somewhat radially outwardlyV from the hub, these vanes however being properlyl curved to catch the iiuid for operating the turbine and to properly discharge said iiuid. f

It will be noted that the inlet port 24 from the inlet duct 9 to the turbinechaniber 7 is at an inclination in the direction lof rotation as indicatedby the arrow in Fig. 3 and the outlet port 25 also has inclined walls fronithe turbine cham-ber 7 to the out let duct 10. The turbine rotor is keyed to .a shaft 26 which may be designated as the turbine shaft. f

Theman-n-,er ofY journaling the turbine Yalf-Mitt"is. Substantially aS fellows beine adr 'cated ,in Fig. 2.

A cup 27 is screw threaded into the recess 8 above the turbine ehamberand a block 28 fits therein, On this block is placed a Ha fingaaae. later supporting ani internal balli-rae@ A11 @stel-nal ball- .race

iin

31, there being balls 32 between the races, bears against the iner portion of the recess 8 and against the fiat inner end .--The shaft 2G has a shoulder engaging the inner ball race and the upper end of the shaft may be slightly coned as indicatedlat 35, extending into the coned socket 3G, this however, is merely afclearance space to allow play of theshaft. The above construction forms a thrust bearing for the shaft as well as forming a centering bea-ring to maintain the turbine in proper alinemont.

A .shaft journal 3'? is formed of the inner and outer ball races 3S and 39 with balls therebetween, these being situated in a journal socket 41 in the-eduction plate 19, this forming a bearing for the lower portion of the shaft maintaining it in proper alinenient.

j A packing of any suitable character .12 is inserted in the internal socket 1li of the packing cap 12 and packing 13 is inserted in a socket All formed by a collar t5 projecting downwardly from the eduction plate 19. This packing is held in place by a flat ring and an expanding spring 46. The lower end 47 of the turbine shaft may be of any suitable shape'and adapted to be connected with various tools. In well drilling operations these may be well boring tools of a rotary type, or if used for surface operations various suitable rotary tools.

1t is believed that the manner of operation of my turbine is clear, however, it may be stated that a fluid such as compressed air will be forced down the pipe 3 through the passages 4 and 5, the inlet duct 9, inlet bore 211 and actuate the turbine by impinging on thev vanes 23. The outlet port 25 leads to the outlet duct 10 and the compress-ed air is educted from the turbine by passage through the discharge duct 16, the annular groove 15 and the eduction ports 2O in the eduction plate 19.

It will thus be seen that the turbine is completely enclosed and protected from the drains of any dirt or in oil or water wells from the oilV or water, the gas or liquid being exhausted, keeping materials detrimental to the action of the turbine from passing to the eduction plate 19. Y

It will be readily understood that in well boring the tur iin-e housing could be main- `tained suiiiciently rigid to prevent it from rotation and thus a high speed boring or drilling action vmay be obtained. If my turbine is to be utilized for surface work, for attaching tools thereto or form the driving power for a pulley or the like, a supply pipe for gas or liquids will be attached to the internally screw threaded end ct the passage a, the turbine housing being of such size as to be readily grasped in the hand or heldin asuitable supporting bracket.

Itis lnanlfei that my ygeneralv` turbine constructionrmay be considerably modified to suit dierent types of work for which it the general features Yand specific details and these modifications will be within the spirit O f my invention as set forth in the description, drawings and claims.
