Be ily known that l, JonN B.\\'EBBER,J1., :l eitizen of the l'nited States, lresiding nt Toledo, linens county, Ohio, have invented [s n new :und useful Fxenvntor, of which the follmvinggj is :i speeiliention. v

This invention relates to :L nnrehine havin" in combination ai plurnlit;y of features, an( more espeeinlly to the control of the complex lo nmehine und its features.

This invention has utility when embodied in n power excavator in which the several features may be simply handled with euse und speed in such succes- `sion und together :is the neeessities of operation require.

Referring' to the drawings: Figure 1 shows an embodiment of the invention in a steam shovel; Fig. .2 is uv medial transverse section' on an enlnrged seule of the excavator' shown in Fig. 1 -in side' elevation with housingpnrtinlly removed; Fig. 3 is a plan view, with l housing removed, of prime mover', some of .y the features driven. thereby and some of the control connections; Fig. 4 is a fragmentary view showing in `vertical section the pivot shaft and clutch eolmeetionsj. Fig. 5 is a side elevation with parts broken away to more clearly show the asseniblal-ge of the cont/rolling devices; Fig. `6 is a de'tail view showing dipper or shovel door unlatehing device; Fig.

7 is an enlarged showing of the ower meehanisrn for operating the unlatc 1i 1g device;

AFig. S is n detail in elevation of t e throttle showing'the connections to actua-.te the exhausting vulve; and Fi 9 is a fragmentary plan of theelevating evice connections to factuate tho boom.

The wheel truck 1 (Fig. 1) has onrts plutform a circular trackl 2, on which trave-l a plurality of bearing rollers 3 antifrictionally sustaining the swingable platform'4, upon which' is mounted the boom 5. Remotely from the boom 5 on platform 4 is the boiler 6,

K supplying through main 7 and' throttle valve f 8 steam for the prime movers 9, The prime movers 9 (Fi 3) drive shaft '10 mounted in frame carried.) by the platform 4. On shaft 10 is pinion 11 in mesh with gear Wheel 12 on shaft 13. Also mounted on shaft 13 is hoistin drum 14, which b flexible. means '15 ig. 1) passing over ul ey 16 on theboom 5, com rises the hoist or the digging member the directing and effectively l On shaft 13 (Fig. 3) is pinion 19 in mesh with gear wheel 2O on shaft' 21, which has centrally of platform 4 oppositely disposed bevel gears 22, 23, each having 'clutch portions 24 (Fig. 2). These gears 22, 23, arf` loosely mounted.l on shaft 21, While disposed between them and splined on shaft 21 is slidable double faced lclutch member 25 movable to friotionally engage geur 22'01' 23, which gears are in mesh with bevel gear 26 on eentml shui t 27, herein shown as the pivot pin for swingnble platform 4.

loller 2S on shaftg27 (Fig. 4) has connecl tion by stem 29 centrally of shaft 27 with bevelgenr 3Q loosely mounted on shaft 27. The'genr 30 is/ provided with a clutch face enacting with clutch member 31 fixed on shaft 27, whereby gear 30 maybe driven to uetunte bevel gear 32 meshing therewith (Fig. 2). Bevel geur is mounted on shaft beneath the truck platform 1, and has thereon wheels 34 Connected by chalins 35 (Fig. 1) to wheels 36 on axles 37 which carry thel wheels 3S of the truck 1. -Also mounted on shaft 27 is oollzl r 3Q provided with a clutch face. This coll-.1r 39 is splined on shaft 27, und is reciproenble to engage eluteh'fnce of bevel gear 40 loosely mounted on shaft 27. ltfeshing with bevel gear 40 (Fig. 5) is Vbevelv pinion 41 on shaft 42 having gear43 concting with toothed way 44 on the. platform of truck 1, the driving of which 'eonneotions'effeet the swinging of the platform 4.

On shaft 21 (Fig. 3)is pinion 45 meshing with gear wheel 46 on shaft 47. The shafts 13, 21, 47, are mounted in a common frame on the platform 4. drum 4S, 49, from each portion of which ex.;-v tend reaches 50 (Fig. 1) of the flexible means passing over pulleys 52 (Fig. 2) held by links 51 (Fi 1) extending from the A-frame 53 Steppe Y in lugs 54 of the drum shaft framel frame 53. By thus strutting the A-frame between the downwardly tending forces near its top against the -upwardly acting riUid and compact construction is produced w ich will not be distorted in operation to work itself loose. 1 l

Taking lexiblemeans attached to drum l 48 (Fig. 3), it extends over right hand ulley )52 (the left 'Fig'.Q) to correspondingpu ey 56 in block 57 o n boom 5 (Figs. 1 and 9), thence l baek over the saine pulley 52, about pulleyl On shaft 47 is double Rearwa-rdly extending bars brace the A-` forces upon the drum carrying frame, a most roo control and rever-.5c prime movers t).

58, from whence it extends similarly over the other pulleys 52, 56 and 52 beck to drum 4) (Fig. 3), thus continuous to insure uniform actlon in operating theV device in elevating the boom. The laterally spaced reaches of the flexible connection of the hoorn elevating device, besides permitting thc boom to locate ih n. stable central position, allow for uninterrupted passage of connection 15 of the hoist as well as upward extension of directing member 1S through the boom 5.

Connected to the boiler (Fig. 1) is steinn line 59 extending to the booni 5. On the boom 5 is pilue mover 00 driving pinion 61 to rotate gear wht-cl til. .having connection with rack 3 on the directing member 1S, whereby thc shovel 17 may bc thruet away or drawn toward the h'oom.

Forwa-i'dly and near thc right hand corner4 of platform 4 (Fig. 3) the operators station, without moving from which station an operator may control the many operntions'of this power driven nnrchine.

Hand lever 64, (Fig. 5) through link 65 may rock shaft G6 having arm (i7 effective to Foot lever or trcadle 6?# held thrown by spring catch 69 against resistance of spring G8 has arm 70 (Figs. 3 and .-3) connected to rock shaft 71. Arm 72 on shaft 71 is connected by link 755 with lever 7-1 having pivot 75.

The lever 74 has two arms 76 connected to band friction 77 on druln 14 to serve es a brake in stopping the shovel hoist, and. which may be partially sot in lowering the shovel.

The stein 85 is connected to collar 86, th(` rct'tipromtting of which through linknge S7 ell'ccts rocking ol' cranked .shaft Sh. carril-d by gear Wheel 12. v()n thc opposite side of gear whcel 12 from linkage S7, cranked shaft 88 has arm #41) connected to friction bandQO about drum 14, so that by tightening thc band there is n. friction clutch to drive the hoist from wher-,l 12.

(ln the side of Wheel 46 opposite linkagc 11297 cranked shaft 13() has erin 13.1 engaging friction hand 132 about drum 48, 4E), forming a friction clutch for driving 'the ele vating device from wheel 46. 1&3, spring raised, (Fig. 3) is heid down by catch 184. 'lhis lever or treadle 133 is connected 1o rock shaft 135 exteuding'across the forward portion of' platform 4, which rockshaft hasarxns 136, 137 (Fig. 5) connected to friction hand 138, so that in controlling the elevating device there is a. brakewhich may he additionally used in lowering the boom by partially settii'ig friction und throwingr out paw] 110 until adjusted position desired is reached.

At the operators .station and above the bank of levers just described is lever 139 connoctcd h y link 140 to lever 141 (Figs. 5 and H) having pivot 142. .This lever 141 loosely fils nhovo )in 143 in forked valve stem 144 of tlnthrottlc 8.

The ycertainty "of this feature is a safeguard nguinst damage 'to wagons in dumping therein.
