4 DUMPNG manon l.' This yinvention relatesitoy dumping trucks,
l and among otherobject's, aims to provide,V` improved ,mechanism for initiating r the dumpingmovement ofthe body.
5` vThis is a companion application tothe '-apf plication [recent-ly filed by us, Serial No@ 215,714. This ypresent invention is an fini-j e provenient onrr the mechanism described and y claimed in the pending application offirthur yl S. Hughes, Serial No. 789,803.
In the accompanyingdrawings showing afY preferred embodiment'of the invention 1 Fig. 1 is a sectional Jelevation ofmechanism of they characterjdescribed, interposed ber' `iti'tween and connected to the lower portion of u a dumping body and itsframe or chassis,Y
if fragments only of the body andl frame beingVK parts -being in latchedposishown, 'and the tion;
" Fig.` 2'is asimilar view, but showing the i parts yunlatched and the body moved Vpartlyk toward vdumping position z Fig. 3 is a'lcrossjsection, looking toward the front, showingparticularly'the latch and" n yoperating rod; and
, Fig-dis a view like Fig; 3 but showingthe e strike plates and omitting the latch.. f 1" -Referring specifically Y tol lthe drawings,
, there is showna portion of a dump body .5, 30. which maybe of various types but preferably dumps-to the, rear. For convenience in de,-
scrption, the body 5 will'be assumed to :be
of this type, although the inventionvis apf-V ,f plicable to bodies dumping otherwise.A The supporting frame 6V may be the vehicle chas-` sis, or aseparate frame secured uponthe chassis proper, and in either case kprovides a support for thedump body, whose forward endrises and rear end descends in the dumping operation. The rear portion ofthe body 5 is supported on frame 6 either Vby rockers,
as disclosedin said Hughesl application, or
nby rollers as. disclosed, for example, in thecompanion application referred to above.
The latching'mechanism, by which the body is heldjdown, in material ,conveying position, consistsof a-` keeper 7 securedto the, body, a latch ,8 carriedl on the frame, and anv i f operating rod or rock shaft'9, which may be "j vmoved vby a hand lever (not shown, but dis-k closed infthefcompanion application),v Con-* y venie'ntly, the keeper .7A Iris mounted kon ,Y A y q 10`secured tothefbottom-of body and; eXtelflding crosswise. thereof. Latch 8` is;`
shown as Vfreely pivoted on rock shaftrk 9,.4
which is rockablefon its'. axis to move a' latch releasing arm A11 rigidly'secnred to therock Asha'ft'lan'd engaging a lugf 12 on thelatch." Bearings 13 on strikej plate14 are.. providedY gforkrockfshaftf). i er `The ,-strike'kplate llis carried bythe frame.
6, prefferably on 'a transverse ,angle` 15",' along 16 secured tothe body'at such aV point that whichfrockjshaft 9 extends.romloneside'ofthevehicle, as indicated in Fig. 3. Ceoper ating witlistrike'plate 1liV is a similar vplate 65 e thek two plates meetwheneverithe body is re-jf stored to its normall position.v
To prevent disal'nein nt Vto play. developing in the lrear supports, the
strike plates/fhave;engaging surfaces (Figf, 4) which are' so' shapedthat they cententhe Y body each time it `falls."k This centering pre! vents undue strain on certain parts'connectingthe body and frame, as .willbe understood To hold thelatch engagementwith its keeper, a spring 17 "may connect Tan 'arm 18' of thelatch with some part rofthe frame, fas kthe rangle `15.` As theylat'ch rocksindepend-r ently offtherock shaft9, jthe'spring will cause it tojeng'age the keeper each time the body moves to the position of Fig. 1. To retract theflatch," kthe rock shaft 9 i's'moved clockwiser asview'ed'infFig. 1.
The body 5 is preferably soinounted and so of the body me 'zoV loadedlthat its center of gravity when loaded` isflocated" rearwardly ,of "the .fulcrum' on which the bodyjrocks, so that it will move to dumping position without the application of power, when rel-eased from the latch.' Somei times the load` cannot be placed just right,H or 1sr ofa nature whichprevents itsV conceni trationr toward the rear of the bodyin which e cases the body may have no tendency to dump even when released; Y Hence'it is desirableto provide means to give` van" impetus ftoithev" f, body to movetoward duniping position. As, i ,l
shown, vthereis;aswin'ging armi 19fxed t the' rock shaft-9.50 as to be moved clockwise kalm e aid ook shaft or toward the'kbody when .releasesthe latch.` The swinging arm lQina-y directly engage the truck body, or, as shown,
to eliminate friction and wear, mayengage a roller carriedA on angle 10 in thepath of the'swinging` arm.'Y
j; dumping. Y
As dumping depends'largely on distribu- Y horizontal ositioii vwhenem t it follows l) a v vthat during dumping, whenthe lcadghifts longitudinally or" thebody,A the body hasa tendency'to fall beforefall;the-load@ is out of it. To prevent premature return of the body, gle lock is provided, said toggle lock compri i iig-in this instance, two links 21, moyableinto and out of'alinement., between their; respective pivotalconsimple pivot, as is -custoniary in such' linkages; butwe vpreterto provide a lost-mo'- tion71 connectionV with a shock-absorbing member, to takethe shock oistopping-,the bodygatvthelfend of'its dumping` movement.
A-sshowinlink 21' has a slot' E25-'at its end and linkj22has. a pin26 slidable in saidislot. A coil springl 27 connectslink 21near its slot with the lframe, and is soarranged that it is expanded when thelink's are longitudinally ialned," asoccurs whenever the truckl is dumped. The momentum. ofthe body kat the end ofthe dumping movement-will momentarily-expand'the springA as .the links separate to the greatestl extent permitted byl slot 25 Aand pin 26'; then the tension ofthe spring will Vcause pinA 26 to return tothe upper end' of the slot, where it will'remain as long as the toggle is unbroken. Thus undue strain on the pivots of links 21, 22 is obviated,A
. Itis advantageous to provide for adjustment of the latching mechanism". In the present instance, the keeperis adjustable aus best shown in VFig. 3, being slotted asat' 28 and clamped by boltsv 29 passing4 through angle v10; To prevent change in the adjustment, the keeper is held by a pair of bolts 30 which are locked upon the strike plate 16' by nuts. Conveniently, the strike plate 16 has ears 31 through which bolts 30 pass, andthe keeper'has alined ears 32 for the same bolts.
Thus continual striking ofthe keeper againstthe latch' cannot shiftthe keeper and'- thus make the latchdnoperativd At the same vtime,l adjustment is always possible.
, To prevent'movementA of the bodylifting arml) too far underneath the body, vaprojection or stop Sii-is provided. This stop-is shown in Fig. 3 as being carried by the link This arrangementvis advantageous, be-
cause .when the .links straighteirout to lock theV body, the-stopv 33 willfthrow arm 19 to Thus rocking of shaft 9 'notronly releases the body, but positively moves itthrough a suiiclentangle to insure the left, or counter-clockwise, out of the way when the body descends. vThus the end of arm V19 cannotfoul with thekeeper 7 or the plate l5 or become stuck'under the'framing of the body. This motion'of 4arm 19 will also restore the rock shaft 9 and all parts actuated Vtherewith to, their init-iagl'posit'ions (Fig. l),
on one member'oi`-`the toggle lock andvv ini thev 35 y nections 23, 2da-with the' body and'frame. The links 21,22-may be connected by means vot'a chassis, said projection being in the pathof said pivot'ed arm andf engaging said pivoted arm as` the -linksgstraighten out during-elevation ofthefree endofthebody, and push'- ingisaid pivot'ed arm-out ofitherwayofi the body s'o-thatf descent offthefbodyis not pre- 105 vented by the upper free endofsaidpivoted arm.`
