Referring era'tively connected to-the rezrch rod=,=5'l-, "by
first to Figure 1170f the drat v vings thereihas-been ln'dicated generally adjacent.
eseht Referrin now 'to'Figure- '2 or the clrawings; there is provided a 'osisingl struture 10,:
5 Within which is nionnted the. gearing for op erttin'g the tuinhling shaft, 9.; "This gear'ing 7 includes. primarily "an actuating: rbd 15 reclprocated in a'riydesiredmanner, (prefer ably however frome power oylinderfP at a distant point) Suich rod 15 has a doiihle spiral groove 16; 17, yvith which engage pro jections 18,19 on ai -sle've' 20.

by providing the twosepatrahle nested sleeves- 20, 22, injury to orwear of'eithelro f the sleevesywill not require disczirdingl Lofboth,
The hollow center of the caslng'structure, 10, above described, is provided with suitcellar for the several gearing elements.
It will readily be appreciated that the sev- V eral parts, to-wit': the bushings, 27, 27, bearings, 28, 28 and 'end caps, 29,30, together form removable closures to enable the disassembly of the gearing mechanism from the casing. To permit of such disassembling operation being readily performed, the means securing these several parts to the casing, 10,
"are all easily reached fromthe exterior of the casing 10. V V v For enclosing and protecting the projecting portions of the rod 15, there is detachably applied at each .end of the casing, '10, housings, 15a, 155, which further serve. to prevent the ingress of extraneous matter such as dirt or moisture into the casing 10.
Referring now'more particularly to Figures to 7 of the drawings wherein there is illustrated another embodiment of the. invention, it will'be observed that there is here again illustrated an adaptation of the invention to the Baker-Pilliod type of valve gear for controlling the admission of fluid to the locomotive cylinders,indicated generally at A. This is connected'as before to the tumbling shaft 9 by. the socalled sh'ortreach Turning now to Figure 6 of the drawings, there is shown a casing 10 w1th1n which 'mounted the gearing for operating the tumbling shaft 9. This gearing includes pri marilyan actuating rod'15 reciprocated in any. desired manner, as before suggested.
Suchrod, 15,is non-circular, and is,supported in the casing for through. I j
reciprocation thereing 10 and against longitudinal movement by means of'the bushings 20", one of and 10".
which is disposed in the removable cap member 11 and the other in the casing '10', and
thereduced outer end-of the gear-member 18 V is disposed in a bushing 20 carried'ina re-' c movable cap member 11".
The spiral worm'18" engages a segmental rack 21 carried on the tumbling shaft, 9,
in the casing 10.
' The casing 10 is made in two parts, 10"
These parts are detachably attached for ready separation in .any' conveni- \ent manner.
It will beobvious upon'inspection of Figure 6 of the drawings that this construction permits the removal of various elements contained in the casing 10" with facility.
For enclosing and protecting the projecting portions'of the rod, 15, the casing, 10, is provided at one end with the integral housing extension,15c, and at the'other end with the housing 150? detachably mounted thereable cap pieces, 29, 30, forming a lubricant u 011'. I i It willbe understood, of course, that the worm and segment structures 18, 19, and 18, 19, above described, provide an irreversible I connection for operating the valve gear mechandholding the gearing in predetermined relation to the caslng, and a-member mov able through said casingfor actuating said gearing, said member extending beyond the casing, and'a housing structure on the casing forenclosing the projecting portion of said actuating member,- both the closing meinbers andthe housing structure being attached to the casing by meansreadil'y removablefrom the exterior ofthe casing, whereby the gearing and actuating member may be readily dlsassembled from position in the casing 2. In a reversing gear mechanism, in com bination, a gearing casing,a revoluble element in said casing, a member movable through said casing for imparting rotary movement to said revoluble element,an' end bearing in said casing in which said movable member moves and by which said revoluble c element is held against endwise movement in one direction, said movable-member projecting beyond both ends of said;v casing, means for readily removably retaining said bearing, and a housing at each end of the casing and extending therefrom to enclose those portions of the movable memberextending beyond the casing. i
3. In a motion transmitting mechanism forming a unitary structurefadapted to be attachedto a power operated mechanism and to receive a part of the tumbling shaft of a locomotive reversing gear mechanism which includes, in combination, a casing provided with a chamber cont-jainingbearings' forthe tumbling shaft, a segmental gear receivable in said casing for attachment to said shaft, a revoluble element mounted in a portion'of said casing adjacent to saidchamber. and operatively engaging with said segmental gear to form. an irreversible connection, an end bearing in said casing for preventing endwise movement of said revoluble element but, upon removal of said bearing, permitting the ready removal of said revoluble element without disturbing said segmental gear, and a motion transmitting element extending "through said'revoluble element for impartl ing motion thereto, said motion imparting element being mounted in said end bearing.
4. In a bodily removable unit mechanism for operating locomotive reverse gears and the like, in combination with the shaft to be moved, a casing having separable parts adapted to embrace said shaft and form spaced bearings therefor, a segmental gear in said casing adapted to be affixed to the portion of said shaft between said bearings, a worm in saldcaslng for driving-sald seg-' mental gear disposed on an axis at an angle thereto to form an irreversible connection,
bearings in said casing for said worm readilyremovable to permit of removal ofthe worm, and a reciprocating member extend' mg from said casing and mounted in bear 7 ings in said casing and operatively connected to impart movement to said worm, removal of one of sald worm bearings permltting removal ofthe worm and said reciprocating member. v
