reference is made thereforto my copending ap-- plication Serial No. 655,744.v

As appears most clearlyfin' Figural, the main body it! rests upon'and is directly supported 'by a foundation board. or .platiorm ll having V the vehicle frame, the attachment of the short flared extension chute,.2|,, such as is shown in,

' either side of the-,flared-end of; the extension formed therein an elongated central opening I5.

board or. platform 14.

, of partially boxed-in sections the vertical side walls of which are each provided with a centrally disposed opening l1.

tom end of the main body In is a revoluble discharge chute 20, the vehicle frame l6 being of a sufficient depth to allow forthe desired vertical and rotative movement of the discharge Chute Z The vehicle frame I6 is of substantially rectangular formation, thus permitting not'only a vertical movement of the discharge chute; '20 therewithin but also a circular movement thereof-when the body I0 is in lowered position, the openings I! in the side walls of the vehicle frame being of suflicient length and depth as to permit the free movement therethrough, of the outer end of the discharge chute.

As appears most clearly in Figure 4, the free end of the dischargexchute 20 extends somewhat beyond the side limit of the vehicle frame when thef'chute is, directed into position'for discharging the load from the side of the vehicle, thereby facilitating'the filling of receptacles from either side of the vehicle when the main 'body ll) isin its loweredposition. At the same time,

by {so arrangingv the discharge chute that its outer end extends through the opening I! of Figure 6,."is;greatly facilitated. As appears most clearly in Figures 1,-4 and 5,

, the'revoluble discharge chute 20 is provided at opposite sides of the discharge end thereof'with a"pair"of,chains,221to which are adapted to be respectively hooked the hooks23 arranged upon chute 2|; t .Suitably secured to'the upper end of the circular body of thedischarge chute 20 is, any annular rack-.bar or worm gear 24 which is adaptedfor meshing engagementv with and ac-v tuation by a-worm. 25 fixed to a transverse shaft 26 the opposite ends of whicharejournalled, as at-26 (see Figures3 and 4), to 'the foundation Keyed to one end of this shaft 26 is a'bevel gear 21 in mesh with abevelgear 28, the. latter. being non-rotatably but slidably. secured tos a vertically extending rotatable shaft 30. This shaft'30, which is provided with aflongitudinally extending groove 29 within which the bevel gear 28-isslidably keyed, is suitably encased within azsupporting tube or casing -3I-whichis securely held in position at its upper end by a bracket 32 (see Figure 3) mounted-upon the side: of the main body I0.

,-Secured to-the lower'end of the shaft 30 -is an operating handle 33 for effecting the'desi'red rotationtcf the revolubledischarge chute 20 from thenground regardless of the vertically adjusted position ofthe main bodyfit being apparent that asthesaid bodypis raised or lowered, ,the transverse shaft 26 is correspondingly moved therewith-asisthe bevelgear 28, the latter being constantly in mesh with the 'bevelgear 21.

Preferably, the lower end of the rotatable shaft Disposed between the openings [1 in theopposite side walls of thevehicle frame and suitably secured to th'e'z'bot-' 30 is journalled within a bracket 34 (see Figure 4) mounted upon the side edge of the vehicle frame I6.

Mounted upon the vehicle member l6 of the vehicle truck at the fore and aft ends thereof are a pair of body elevating means 35 and.

Inasmuch as these means are described in detail in my copending application aforesaid and in view also of the fact that any suitable elevating means may be employed to elevate the body [0 as desired, the construction of the particular elevating meansv shown will not be described'herein in detail, it being sufilcient for the presentpurposes merely topoint out that each of these elevating means embody a standard ill-within which I is journalled a'vertical 1 screw 38, the latter operating upon a block 39 to 'raise and lower the same. are in turn respectively connected to opposite ends of the foundation board l4 through suita- The blocks 3939 ble cables 40-40, each of" which passes over suitably journalled pulleys and 42.

Preferably, the upper ends of the fore and aft standards 31-31 are* preferably. respectivelycovered by the caps" 43 retained v inipositionby 26 means of thescrew bolts 44.- These, standards 31-31 are respectivelyslotted; as at 4'5,--in the faces "thereof which present toward eachother inordertto permit the free vertical movew ment of the substantiallyT-shaped extensions 48 provided at either end of the foundation-I board or platform I4, these extensions beingretainedwithin the standards 31- -31 and guided during the vertical movement of the platform by the vertically extending ribs 4'l which define the vertically extending slots 45 in thei'standards. Preferably; the standards are I each strengthened and supported by side braces or ribs 48 and 49;

Referring now lmore particularly totfFigures 1 and 2, it will be observed that the mechanism for operating the bottom .trap doors l3 includes a forward pair of transversely extending shafts 50 and 5| and'a rearward pair of'transversely extending shafts 52 and 53, each of said-shafts being suitably journalled upon the bottom gsur-lface of the foundation'board orplatform '14..- The forward shafts and respectively have fixed theretothe pinions 54 'and'55," while the.

rearward shafts 52 and 53 have respectively 50 fixed thereto the pinions 56 andfi5'l,g it being observed that the pinions 54 to 51 are relatively so located that"theyvrespectively engage the longitudinally extending r'aclrbars' 58 which are respectively securedtofithe several trap doors 5 5- l3' '(see Figure2). Secured to the opposite, outer extremities of the transversely extending,

shaft50 are ajpair of handwheels 59, the transversely extending shafts 51, 52: and 53 being similarly provided at their opposite extremities 6'0" with hand wheels 60, lil and '62, respectively It will be apparent thatby virtue of those handoperated transversely extending shafts and the four sets of hand wheels'arranged' to eitheri side of the vehicle the opening or closing of 5 any one of the trap doors by an ol ierator 'stz'itioned at either side of the vehicle is facilitated.

Still another means is provided for opening and closing the bottom trap doors 13", this latter means including'a plurality'of flexible cables 63 which are respectivlyterminally attached'to the eyes 64 of the rack bars 58, the cablesj63 being respectively passed over the -pulleysf65 which are journalled in the foundation board or platform |4,-the free ends of the several cables 63* being looped, as at 68, to-provide hand grips by means otiwhich the operator, standing!upon theground, may puh or other of the soy cr'al cables 63 to open the desiredi trap door or doors [3% I I I A's appears most clearly in Figures 1 and 2, the main body in has pivot'aily mounted. at oppositesidesthe'reob as at 68,: a pair oi laterally spaced thrust arms 69, one such a-rm"being provided 'for each cable 03. Eaohwof the thrust arms ie terminates in arcuately curved portions having"an arcuatedrslot T within which is adapted tome projected'a pin It provided on eaehracklbar 58. A contracti'le'spring 12 con-' nects" each thrust arm" to the main body Ill, thesesprings servingnormally to pull the severai' thrust arms 60 towardthebody and sodoing: causes the trap doorst3 to be respectively moved into closed'positton, this latter aetiombeingeifected through the slot and pin connection between eachthrust arm '69 and its associated rack bar 58, I

"Still-other nieans may be employed for sole'ctively operating the trap dOOl-SH, one such additional means being described in my copending application aforesaid to permit the operation oi -the trap doors-Horn the cab oi the vehicles I jwsiappe'ars most clearly in Figure-"Z, a supporting rail '13- isxprovided tor use with the extension chute II or the like whenJit is not desired toemploy the revoluble discharge chute 20 This chute supporting rail 1-3 isprovid'ed with: a serrated or corrugated central section, the ends of this rail being adapted for remov able-securement to thebottomyirame defining the bottom discharge outlet of the main body. As appearsin Figure fl this chute supporting railmay-bein the form 01 a straight section the opposite ends of which are provided withan up-= wardlyprojecting supporting arm,- the chute sofo'rmedbeing adapted for connection to the said 'bottomframe so that the corrugated edge thereof extends eitherlongitudina'lly' or trans-i versely across'any longitudinally or tranversely arranged pair of the discharge openings [3. If desired, the chute supporting rail may be rectangular; circular or other suchcontinuous outline with means for attaching the same to the bottom frame of the discharge outlet in such manner that a chute may be suspended therefrom in any one of a number of positions, thereby aifording communication between the chute and any desired one of the discharge outlets I 3. It will be understood that the serrations or corrugations 14 formed in the chute-supporting rail, when the chute hooks 15 (see Figure 6) are engaged therewith, prevent lateral displacement of the supported end of the chute. It will also be understood that the chute-supporting rail, be it of the type shown in Figure '7 or of the rectangular shape or curved shape, when properly mounted in position provides for intermittent use of a chute when the vehicle is being employed principally as an ordinary central drop load dump wagon. -When the chute or supporting rail I3 is so employed, the revoluble discharge chute is, of course, removed from the load receiving body.

As has already been observed, the extension chute 2| is provided with hooks 15 at its rear end which are adapted not only for engagement with the supporting rail 13 aforesaid but also for engagement with a rail 16 carried by and extending across the bottom of the outwardly extending section of the revoluble discharge chute 10. The side walls 01 the extension chute 2 are flared toward'their rear end the flared portions 1t 01 these sidewalls being=respectively" I provided with the laterall-yprojecting hooksfl respectively adapted for engagement with the; chains -22-withwhich the revoluble chute, 10' is equipped. The extension chute It is preferably employed-when it is desired to "discharge the load or portions thereof into receptacles to be fliled,-coal holes, troughs, tram carsand-the like, all of which are'located upon the ground when the body 10' is lowered The ezid l5 on the extension chute 2| are'employed pfln-= cipally when the bodyNis elevated and-"a long chute isrequired. The extension chute' z'l be ing narrower in its main body portion. and hated Without the revolving discharge chute'Zll'. Pref- .erabl-y,-the discharge endof the extension chute M is provided with handles or the like for Y facilitating its: manipulationinto' the desired position.

Asappears most clearly in Figures 1 and 5," the revoluble chute discharge is provhde'cl' with circumferentially extending downwardly turned flange 8| the bottom edge of, Which'constitutos a contin-uous circular track for rotatably supporting the discharge chute rollers 82 which are suitably journalled in bracketsfw bolted or otherwise secured to the bottom 'surface of the foundation 'board'or platform H. When'it is not desired to employ-the revoluble chute discharge; t'hesame' is readily removed from its operative position as shown in Figure 1 simply by loosening several of the bracket bolts thereby permitting the rollers 82 to be movedout of engagement with the track 81 and comic quently permitting the removal ofthe revoluble discharge chute bodily fromv the vehicle.

In order to conserve space and prevent spilling in connection with the use of the revoluble chute discharge 20, a demountable frame 84 is employed (see Figure 2), this-frame being provided with sloping side walls which converge downwardly to form a bottom opening disposed i substantially in a horizontal plane lying 'below the upper edge of the discharge chute 20. This frame, which practically encompasses the four discharge openings I3, is secured in position to cross pieces within the foundation board or From the foregoing description, when considered in connection with the accompanying drawings, it will be observed that a vehicle has been produced having an enclosed revoluble chute dischargewhich permits of a wide range or service, particularly when it is employed in connection with the flared extension chute,

spilling of the discharge load being reduced to a veritable-minimum; Furthermore, the revoluble chute. discharge permitsthe load to be .dis-, charged while the body I is in ,a raised or lowered position, it being further possibleto direct-the dischargeload to a point either within ortwithoutvthe external lines of the vehicle 'frame. ,This is a particularly desirablev feature inall such instances'wherein it is necessary that the discharge load be clear of the vehiclewheels so as 'nottohinder the free movement of the vehiclein either direction once the load has been discharged; Furthermoratwhen. the revoluble chute discharge is removed, the load may be discharged directly from the bottom of the main-body or it may be directed to either side thereof by way of anextensionchute suitably supported by; the chute rails which are adapted ,to be, attached to the bottom of the body as hereinbefore described. 7

The body isself-emptying either in its elevated vor lowered position, it being apparent that the entire'body may be raised or lowered eitherby hand or by motor withoutspilling any of the load. Also, the outlet trapdoors in the bottomof the main body are adapted to be operated from the seatselectively and individually,

'or in pairs, or they may be 'alloperated simule taneously, all. without afiecting the operation of-the revoluble chute or its associated. parts:
