v taking aunit' of bricks from the kilns for 5 loading on barges orcars.r y Y The principal'oi' this invention 'is to provide a dumping fork of this character *adapted to load bricks either in closely packed or loose piles, withouty any undue breakage. In

1Q loa-"dingbrickiorV railroadshipment, itv has beencustomary heretoior' to carryaload of bricks',overv the topv VVoi: a' containerV carried upon fa. flat bottomgon'do'la car andy from that"position droppthe-bricks into, the conn V tainer in -a loose pile. @The containers for this use are ot a standardjpattern lcommonly f known as railroad containers, andare of a v `depth such -thattlfie dumping mechanism-` of y dump rforks now in common use can' not be 2o' reached for operation if the Afork is positioned within the container. By means of this invention, the dumping fork may be lowered into `the'containerito within a ew'inches of the bottomot the car or platform upon which the bricks are to be released. 'Thereuponfa simpley release arrangement drops the torky and then byv raising the crane, the bricks are rolled-off the fork-ratherth'an dropped. .The

' crane in its upward Vmovement raises the back Y Se end of the fork', leaving the'tront endlower until.finallyy the whole. mechanism .assumes a verticalposition as it is drawn from thevcontainer. To l reposition i the fork, it'l is only Y necessary to lower-vit tortheground'sothat it will be brought to horizontal position'an'dlocked ready .for the next load.

rThe fullnature of the invention will ybe understood from the accompanying "drawings and the'following description and claims:

In the drawings, Figure 1 is a sideelevation of the 'fork with the upper lportion thereof shown in central vertical cross section, with a stackot bricks carried thereby shown in dotted lines. Fig. 2 illustratesr the fork lowered with a load of bricks into a container. Fig. 3 illustrates'the' fork` after having dumped the bricksin the container and being i removed therefrom.

the fork may be lreadily swiveledinto any desired position orl4 dumping. frame `and turntable constitute a' support for brick supporting iingers hereinafter. de#Y scribed.Y f f Pivotally supported by the cross beam 17- upo'n the finger shaft 18 there are a' plurality 'of brick supportingngers 19 which extend horizontally or at right angles'to the bars 16. Asfthere are a plurality of said fin: gersthey are adapted tovsupport and carry a'stack ofbricks 20, indicated in dotted lines. However, lfor ndumping Vthe, bricks, said iingers are adapted to. dropdown in the vertical position shown in Fig. 3, 'swivelingzabout the shaft 18.' ForA guiding vand .limiting theA extent of their-movement, there'isprovidedv f 'a stop shaft'21 which moves in the arcuate lslot 22, shownv infdotted lines, lwhereby the fingers will be prevented fromv vswinging 'y back of their vertical position'whendumping`,as well asbe forced beyond'their hori- Zontal position when resetting.;

*Mounted in la vsuitable bracket 23 supported upon the cross bar 17, there is a gear shaft y24 to which is keyed a bevel gear25. On

kTao A Y .Y ably keyed to the holding Vshaft 33'and haveach side of said bevel gear there are'keyed the spur gears26 adapted to engage and mesh4 .with the corresponding segmental gears 27 Y formed upon'an arcuate portion of the rear of each finger.V There is provided a spur gear 26 for each finger so that upon movement kof the fingers 19 about the finger shaft 18, the spur gears 26 are rot-ated, which i in .turn rotatesV the bevel gear'25. Furtherf inore,rthe shaft`24 maintains the fingers 19 in alignment ythruout their 'movement thruk the medium ofthe spurV gears respective segmental gears 27.

Meshing with the bevel'gear 25 k there is a bevel pinion 28 which vis keyed tolthe lock Y shaft 29 extending vertically upwardly betweenfthe bars 16 to the overhead support 14. At the upper end'of said shaft 29, there is a gear 30 meshing with the ridler'gear 31 which in turn meshes with the gear 32`slide ing an external ybearing: Yin said overhead support 14. Mounted immediately above the bea-ring onsaid support and Ysurround- Acylinder 34V providedV with keyways indicated Y ing the shaft 33," thereV is an annularlocking at 35 in which the locking collar 36 is adapted to slide in and out oflockiiigengagement f with the keys 35. 'Saidcollar is keyed upon `the shaft 33 which is provided with the notch 37 for receiving .the pawl 38 `pivotally y supported by the bracket 39 and normally maintained in engagement with the notch'V 37 thefspring 40.

Y v V- Y, g .Y In operation the dumping fork. is applied to aV stack of bricks inthe formation left by the setter wherein the 4lower course of VVbricks aresufficiently spaced apart to 'perl mit the entrance therebetween of the yfingers .19, whereby said'fingers may thus bepositionedunder the next upper course.

the pawl 33 for forcing it out of engagement with the notch in the shaft, and thenven gages and forces the locking collar 36 downwardly outY of engagement with the lockingV keys 35. This unlocks the entire mechanism since the collar 36 is free to rotate; This in turn permitsy rotationof the shaft 33 vwith the gears associated therewith, whereupon the gears 26 are freely permittedto rotate, thus'rcle'asing the lingers 19 so that they are no longer locked infhorizontal position.V Upon raising the fork by the crane as shown lin lTig. 3, the. rear ends of the forks arey elevated while their front ends, being supportjV ed by the bottoinj of the container or the bricks upon which they rest, are caused to slide rearwardly until the forks are brought to a vertical position limited by the stop shaft 21. This permits the bricks' to slide forwardly off the forks; After the dumping action, the vfork is then lowered'by the crane until the fingers engage a supporting surface, such asthe ground, whereupon the Y continued lowering of theV frame causes them to be brought back to horizontal position. Upon this position being reached, theoperator. movesY the Vlever 41 upwardlyV from theposition shown by dotted lines, thus rais# ingthe shaft 33 to whichthe'collar 36 is secured and causing said collarto be reengaged by the lockingkeysr 35and'the pawl 38 to :enter the slot 37 kby means of the spring 40.`
