,Be it known that I, CHARLES A. Fauna,

a` citizen of the United States,

Toledo, Lucas county, Ohio, have invented new and useful Material-Handling Apparatus, of which the -lollowing is a s pecificiition.4

This invention has utility-'when adapted to bucket handlin machinery, many features 0%. n embodied in excavators.

"tion t0 be primarily residing ati and possesses exceptional value when member 8,whi1e' when Patented Aug. 8,1911.

' through Vgear 13, is controlled by prime mover 141, so that the auxiliary guide 15 on Vthe directing member 8, to which the conne@ `tions-A10 lead from? guide 11 and wheel 12,

lmay be held, permitted to move freely, or

actuated. ,Aetuationof uidel will serve @to oscillate or raise and y held, it .limits the travel of thedireeting member to reciprocation in its eneral line of direction, shown .as the arco acircle.

The Vguide 15, while havin bail connections"1 to the lines 10 Vpivote centrally to :avoid binding, is additionally anti-frictiow 'ally mounted `ribbedrollers 16 to effectively avoidl lateral '.shiftin which action is supplemented by :the ro ers ,17, one of which` is shown in sectionin Fig. 3. Y

. Extending from the guide 15-at a central intand between the 'longitudinally extendling elements of thedirecting member 8, is the bail 18 connecting tothe hoisting line 19, which extends over the guide .20 (Fig. 4) from which guide 20 is pivoted. the, link 21 carrying the' movable uide'22. The line 19 ,extends over this gui e 22, about the guide 23V near the outer ends-of the boom 3, thence over guide 24 and throughthe platform 2 to the source of power.

i "Connected'to the movable or iee end of the link 2'1 is the flexible coiiiiectionl exuided as well as re-4 ower the directing y on the member 8, bycentrally tending to the after portion of bucket 2G, the

, forward end of whichlias pivotal connection 27 with, the; directing member or dipper khandle 8; f

lthc bucket, the other l rectingmember 8 at end 37 remote from thel'cliet 26. The lever 38 of the valve 35, is normally so 'held by s )ring 39 that themotive fluid from the cylinder 34 is exhausted through .exhaust pipe 40. Actuation of the connection 36 against the resistance of f spring 39, closes exhaust 40 and allows Inotive Iluid to'enter cylinder 34, force plunger 3B upward and thus laterally engage by means 32, the line 80, normally free y tending from the bucket 2G t0 attachment- 37. This travel of guide 32, carrying the line 30 between the guides 31, .not only interferes with the free ruiming of the line 30, but 'so takes up the lineas to trip the latch to the bucket back and to bring about dumping of the bucket. The positioning of this tripping device is such that the least possible resistance will be given line 30 during the reci'procationso lthe' member 8. The intermediate posit-ion between the high and low directions of the bucket 2 6 -rom thc'after terminus 37 of the member 8 is shown by the dotted line-l1. lt is to be noted when the line 30 assumes this direction it Iruns practically free between the guides The shovel '26- may wwork effectively in certain kinds of material, ltfis especially designed to cut away, accordingto conditions., layers of material, two, three, or more inches in thickness, and to 'add-'to its effectiveness in this duty iinder -'-rsevere conditions, thegmaterial may-bc.v prepared for ready gathering in to i-ll theshovel or bucket 2G, by the cutter 42, shown as f1V working'or digging member rigidly mounted on themeinbcr 8,'4 Centrally of the cutter is the. rib or plow 43 (Fig. 4).

In operation, an excavator vehicle or mounting frainebf a usual type, by slight 'alteration may be equipped with the'. feavtures herein topermit of back action handlinO' g that is, have the machinery travel over the line where the material is to be taken out, a sewer or trench. The directingineniber -8 maybe quite extended as to length, thereby permitting of excavating to a depth considerablybelow the -1nachiiiery- Thus drawn into position for filling of the bucket 2G, the extension of the member 8 past the pivot mount-ing 27 eil'ectively braces the bucket, which islirmly held in position by thc connection 25, drawn taut-by the hoisting line 19, .vhich simultaneously hauls guide 15 toward link 21 to tigliten. connections 10, thereby irinly' holding-the guide 15 at a maximum spacing' from the guide block 9. This results in a rigid holding of the member 8 -at two points and-effectively determines its direction of reciprocation as thev hoisting line 19 actuates the bucket tou-'ardthe platform 2. During Ithis digging 'or iilling operation, the wheel 12 may be held, or the prime mover 14 may even force gradually the workin members into the material. With the bue iet filled, freeing of Wheel 12, will ermit swinging of the member 8 about sha t 6, through operation of the hoisting line 19. This swinging maybe eectedbyprime mover 14, This swinging of the member 8 is upward, and notwithstanding the .long back or rearward extension of member 8, owing to its crooked line or direction, it in `Ano wise interferes with the A-frame, and due to its curvature permits of considerable increase in height of dumping over a straight member. With the hoist line lfreed, after swinging of the member 8 upward, shaft 6 .rnay be actuated to thrust l thebucket u' "wardv still farther whileggudeflfis'hel vor actuated higher.

Upon slaclingiof thei hoisting line 19, link 21 is'pifilled toward the dipperf by the connection 25 as the loaded dipper swings -Ja .downvga @y hanging position aboutQitS ivot'moiiztitipg 27, as showii in dottede-litie'positio .vill In -this position,'the dippe'r' back .i t thev bottom perinittin free discharge as the'` latch is t-rippe, #The cutter itngv be so disposed as tojlinit'- the swing the 'buclie't The turn table 2 lpermits f 4lhsvi'inging the overhangingframe orboomv to such 4point as desired or the dumping Toffrepeat the-tilling operation, the boom is swung over theftrench, wheel 12 is freed or actuated. to cause guide 15 to low, r, withthe member 8 pro extended. "As the hoisting line 19 `is rawn taut, the bucket 26v swings .up i position its back 28 Vreadily latches, is in readiness lfor proceeding.

lVith the connections herein shown, hut-inn the bucketwidth, there is no necessary roughening of side walls to trenchesafnd where straight smooth walls are desired, no subsequent trimming is required. This means quite a v.considerabl'e saving in many instances in practice.
