This invention is an improvement over my application, Serial No. 259,178, tiled March 5th,1928. Y y The advantages of the invention as here outlined are best realized 1when all of its leatures and instrumentalities vare combined in one and the same structure, but, useful deembodying less Vtnan vides a manually Wheeled carrier, as, for eX- ample, a Wheelbarrow having a main supporting frame, and a trough ii'iounted therevon for movement theiealone to disnose the front oblique Wall of the trough as close as possible to the ground. For this purpose the said trough is'movable in th upward posit-ion of the device downward and iin forward tilting relation to said "main frame. These'movements can be accomplished by any suitable guide frame which forms a part/of the main frame, and includes tracks, levers, links and other means Well know-n -in the mechanical arts, or as shown, by a combined slotted and pivoted arrangement, the p' yot constituting -a follower movable along the guide slot. Further, the trough has members having guiding Vcoaction with the main frame 'to eliminate any tendencv to lateral movement of the trough with r .l ect to the frame. Any suitable 'locking or securing means serves to holdY the trough againstv movement on the main frame from the noi'.-

mal position. On release of the locking means, and upturning of the device, the trough moves easily forward on the carriage, and is easily permitted to `swing away therefrom. lil-,lith toe lguide frame new extending substantially vertical, the handles extend at g a convenient inclination to permit the device Vmounted on the main frame itself. Vthe wheel'is shoivn'as Vbeing mounted on both manipulated. Anti-friction means may cooperate With the frame and the trough to permit the device to be easily run along the ground in the upturned position mentioned. After the initial movement into the pile has been completed, the handle means is disengaged, and the' same brought up and locked with the guide frame. Then the operator pulls the handles toward himself to return the handesto the ground to tilt the body upward to 'uniformly receive the load. Then the trough is retracted by the operator grasping the rear Wall thereof, the trough riding easily rearward on an anti-friction device, and seating uniformly along its entire length on the frame of the carrier. Asc-oop may be used, if desired to'coact with the front digging Wall of 'the trough to increase the quantity of material that may be picked up by the device, the said scoop being movable out of this position to permit dumping of the load.

Within the scope of the invention, the several members constituting the guide frame may be embodied in a simple rectangular franie consisting of a` uniform L or T section, the trough having guiding and svviveled en- ;iagem'ent with the parallel vflanges of the guide frame, and the latter being connected at its front end tothe axle of the Wheel. W'hile tl e guide frame is shoivn pi voted to the handles the axle oi the Wheel, this pivotal engagement may be provided at any other suitable point, as lfor instance, at the toe of the main frame. The pivotal ymounting for the trough may then be omitted, and the trough merely slide along lthe guide frame. The trough may be considered as being pivot-ally Thilo the guide Aira-me and the handles. it may be mounted on butveither one of them alone. Any other Wheels, auxiliary to the main wheel, may also be employed on the frame.

'Although the invention is shown as einbodied in a u'heelbarroiv, it will 'be understood that the same is applicable `to Wheeled carriers of various types.

Referring in detail to the drawin 20 denotes a device embodying the invention. The same includesatrough 21 that is mounted upon amain frame 22. The latter is supported to Abe readily movedalong the ground by any suitable number of Wheels, 'preferbly one, which is shown at 23. Co-operatir f with theavlieel v23 is an nnderbrace or rest Qthat is `utilize-.fl when the device is resting in stationary normal position on the ground.

The trough 2l is mounted on the frame in any suitable relation thereto, prefearbly in Vthe conventional manner practised in wheelbarroirs so that the dei'fice can be readily moved along the ground by Van'operator holding the handlesQ at their rear free ends Q6, Furthermore, the trough 21 is retained as a bottoni 23, aides 29, and front walls 30 and 3l,.respectively.v The said trough is const "acted oi any suitable mate rial, as for example, metal, and is braced in any required manner to withstand all the strains towhich it may be subjected. rl`he structural bracing` that might be provided for the trough may assume many different forms and it has therefore been preferred disclose the same herein. At any rate, it will be noted. that the liront wall 30 forms a coniparatiyely large oblique ansie with the bottom so that the entire contents may be easily dumped and caused to slide ofi" the front wall 3() in the position shown in 2. y

The main trame 22 includes a guide trame 32 that is relatively movable with ect thereto. The said gui-de frame is pivotally supported at its front end directly on the axle 33 ot the wheel, and at its rear end on the handles 25. l ie latter extend at a suitable angle with respect'to each other as shown in Fig. 3 in a manner well known in wheelharrows, and the front endso't the'handles are suitably anchored together by means of cross or toe brace 34. rlhe underbraces 24 are secured to tl e handles 25 and may be rre-enforced by any suitable cross members as shown at 35. Any additional cross bracing?,l can be provided for the handles 25, as, for example, by means of a bar that extends along the underside of the handles and has upwardly directed end flanges 37. At the front ends of the handles are a pair opt locking; abutments 3 rlhe latter eoact with and may jorm a part of the toe piece34. ln 'the embodiment oty the invention` shown the devices 38 comprise arcuate bars 39 that are .secured to the l i llesand e. end trontward thereoiE and terminate in the transverse pins 40. The bars 3S) can be made o? any reuuired length, and may be no longer than the toe piece 34 itself. i

The guide frame 32 comprises a pair ot parallel guide means along` which the trough is slidable, said guide means being pivotally mounted on the axle and the trough being` movable along the guide means downwardly with Vrespect thereto in t ie upturned position of the oevice, and wi. li the said trough, furthermore, tilted away from the.

trame in ra forward direction. zThis torward tilting motion of tee trough is not absolutelyessential, and may be omitted inasmuch as` the guide frame 32 may assume the required inclination about the pivot 33 so that the. trough may extend always at a fixed relation or angle to the guide fra-me, and nevertheless override the wheel 23 and also not to Y the trough lie with the front wall in comparatively close proximity to the ground.

The guide frame 32 may include a plurality of bars 41 that are made ot' any suitable material as, for example, wood'. Their front ends 42 terminate approximately at the axle 33 to which they are connected by means of any suitablebearings 43 which may be like the bearings 44 on the handles 2F. The bars 4l are cross braced in any desired manner, o

as,.f.or example, by Vmeans of a pair of parallel metal bars 45 which are interconnected by means ot straps 46. in the handles 25 and inrelatiyely close proximity thereto and preferably follow the inclination oi the handles, although within the scope ot the invention, the bars 41 may also be parallel to one another. Included in the guide trame 32 are a pair orn guide members 47 that are secured to the bars 41. The guide members 47 are parallel to each other, and accordingly in the construction shown, form an angle with the bars 41. Wlhile the guide members 47 may be embodied in the different terms, as, for example, in structural sections, which may also include the bars 41 as an integral part thereof, l have shown them herein as being in the nature of Hat metal plates which are connected to the bars 41 in any well known manner by meansot' angle clips or straps or the like. Also the plats 47 may be secured to the braces 45 and 46. It will be noted that in the normal position of the device, the bars 41 are disposed between the planes donned by the handles 25 as clearly shownin Figs. 1 and 2. rlhe plates 47 are ofminimum width above their supportingl bars so that the trough will be kept down as close as lpossible to the main trame. ln order to adhere as closely as possible to standard wheelbarrow construction, the plates 42 are wider at their front ends and ytaper down toward their rear ends, thus corresponding` to the wooden wedges that are well known in wheelbarrow construction.

ln order to 1facilitate the movement oitl theA trough downward alonethe `guide frame 32, the plates 47 are slotted lengthwise as shown at 48, and the trough provided with any suitable means to engage within the slots. As one means of accomplishing this purpose, a plurality oi angles 49 are extended along the bottom of the trough in parallel relation to one another. The horizontal flanges are secured to the bottom of the trough, while their vertical flanges lie preferably along): the inside faces ot the plates 47 in easy sliding` contact therewith. Secured to the angle bars 49 at the ends thereof is a pivot bafr 50, the end portions ot which are slidable along the slots 43 with the bottom of the trough in spaced relation to the. plate 47. The rear ends of the slots 48 are recessed at 51 toward the bars 41 to receive the pivot bar 50 and permit the trough to drop down with the rllhe bars 41 lie withbottom thereof seating directly on the plates 47. Thus the pivot bar acts as an anti- P tion means that permits the trough to be easily `retracted with its load. While the reaction occurs, the bottom of the trough will notc'ontact the plates 47. Then fully retracted, however, the trough reliably seats on the plates 47 and relieves the pivot bar 50 of all strains due to the weight of the trough and its load, while the wheeled carrier is in normal, horizontal position. Spanning across between the plates 47 is a roller bar 52 that is `journaled in the plates and is so positioned that the vertical flanges of the angle members 49 are adapted to ride thereon, as, for example, in the position of the device shown in Fig.. 6.

ln order to limit the maximum angle that the guide frame may make iith the handles 25, any suitable stop means variously positioned can'be used, as, for example, the angle pieces 58 that are mounted on the handles 25 and are adapted to abut the bars 4l.V

The members 49 have recesses 54 formed therein to receive the pins 40, whereby a strong abutment engagement is effected between the trough and the handles 25 for strong forward actuation of the trough into the pile of material to be dug. These recesses 54 are of such forni that the pins 40 may be readily received and released therefrom. Due to the coaction of the stop 58 with the pivotbar at the lower ends of the slots 48 in Fig-4, the pins 40 may be readily engaged within the recesses 54 without the slightest dilhculty. Brackets prevent the roller bar catching in the recesses.

ln order to retain the guide frame 82 in normal engagement between the handles 25, the flanges 87 are formed with L-shaped slots above the plane or" the handles 25. Disposed within the slots 55 and extending across from handle to handle is a bar 56 which is `adapted to take over the free rear ends 57 of the guide frame ln order to release the guide frame 82, the locking bar 56 is moved in areal-ward direction to the toe of the L-slot, thus permitting the ends 57 to clear the said bar. However, when itis desired to engage the handles and the guide frame together, the locking bar 56 is brought over the ends 57 into the part of the L-slot remote from the toe as clearly shown in Figs. l and 2.

In order to lock the trough to the guide trame, links 58 are conne t d to the pivot bar 50, these links being positioned inside of the members 49. Extending through the other ends of the links is a rod 59 Securely attached. The plates 47 include portions 66 that are notched at 6l on their underside edges. The links 58 together with the rod 59 are swingable about the bar 50 as a pivot into the position shown in dotted lines in Fig. 2 and with the said bar seating in the notches 6l. Since the pivot bar 5G is strongly secured to the structural members 49 of the trough, the latter is thereby held against downward movement with respect to the guide frame 32. In order to breakthe strain that would be caused bv the weight of the body and its contents, as, for example, in dumping position, upon the links 58, the pivot bar 50 seats in the recesses 51 in which the pivot bar is reliably ire-tained by the co-operating links 58 and the rod 59. To permit the trough to ride downward along the guide frame, the links 58 are thrown upward into the position shown in Fig. 4, and with the rod 59 riding along the edges 62 of the plates 47, if desired.

ln order to hold the front end portion of thetrougli reliably on the guide frame, hooks 63 are secured to the members 49 or to any other convenient portion of the structure, the hooks being directed as to receive the roller bar 52 when the trough is returned to its position on the guide frame as shown in Fig. 2. This locking arrangement acts automatically both for engagement and release, accoroing as the trough moves into one or another position.

lf it be desired to afford lateral support to the trough to facilitate the return thereof to normal position as .shown in Fig. 6, there may be provided on the underside thereof a chann-el 65 that extends centrally longitudinally along the bottom of the trough substantially the entire length thereof and flares downward as clearly shown in Fig. 9 to readily receive and engage the peripheral portion of the wheel 28. The latter provides a rolling support for the trough in the positionV of the device above mentioned.

If the frictional resistance of the digging wall 30 of the trough with the ground be a factor in the operation thereof, a plurality of rollers 66 or other anti-friction means can be arranged to suitably space the said wall from the ground. The said rollers are preferably set into openings 66a formed in the front wall 30, which openings are closed in any suitable manner, as, for instance, by means of casings 67 that extend into the trough and are properly conneced to the wall thereof, the axles for the rollers being rjournaled in any suitable manner in the side walls of the said casings. ln order to increase, if` that be necessary, the size of the load that may be dug by the trough, a. scoop 68 may be mounted on the trough, the use of which may be rendered optional, depending upon the operations in which the wheelbarrow is employed, the material that is to be dug, and also upon the skill of the operator. rlhis scoop 68 is pivotally mounted on the trough at 69 byrmeans of any suitable brackets, as, for example, those shown at 70. fl`he pivotalmounting at 69 may be rendered detachable if Vfound most convenient. The scoop 68 Yincludes the side wall portions 7l 'vertical position or, inclined slightly toward and a front or digging wall portion 7 2 which in the position shownin Fig. 4, lie within '-.he trough and with the wall 7 2 constituting a straightforward extension of the wall 30 of the trough.. The wall-72 will afford. possibilities "of digging a very large load and also oi retaining),l it suitably within the trough whenthe wheelbarrow is being moved along from place to place. In order to dump the conf` ents of the trough, the scoop (iS-ismoved rearward of the body` and into the position shown in Fig. 2, so that the front wall .30ct the trough is free of even the slightest obstruction and is nevertheless at a suticien I height above the groui'id so that the contents' of the wheelbarrow can be easily dumped. This rearward position of the scoop may be used when moving the'wheelbarrow around from place to place, or it maybe liep. in the forward position, whichever may be found most convenient or desirable. If the sider walls 29 of the trough extend at an inclination towardeach other, the Scoop may, in the rearward position, lie along the ouiside" of the end of the trough. In the dumping position, the scoop may be either gravitationally retained in Vits rearward position, or it may be locked there.

The operation of the device will now be clearly rappa-rmit. rlhe wheelbarrow being in i horizontal position on the ground, the lock-

v ing members

56 and 59 are released, permitting the trough to be pushed forward along the guide' frame 32, over the wheel, whereupon, on upturningy the main frame, the guide lrame and the handles are readily separated a ularly. l'llhe yformer is in substantially the rear trom the'axle 33, while the handles 25 extend,rearward at a suitable angle so that the ends 26 thereof are at a proper height above the ground to be conveniently manipulated by the-operator. rlhe pins 40 engage in the recesses 54 in the members 49, this being facilitated by thev coactionot the stops 53 which limit the'angle as between the guide` traine and tl'ie`handles25. A slightdownward. pressure maybe exerted on the ends of the handles to bring the pivot bar 50 strongly` into thelower ends ot the slots 48, andfeven it necessary, to slightly raise the trough so that the pins 40 will instantaneously snap: into their recesses. he scoop 68 Inayhave been previously thrown into the forward digging position. vNew theoperator, acting on the handles at a slight rum-drives the device stronglyintoa pile'of material. Thereafterl the handles 25 are'brought into substantially upright position into the plane oit thebars 4l ot the guide frame. By doing this rapidly, the locking bar 56 vwill automaticallyr be thrown from the toeend of the L-slot forwardand downward along the slot to engage over the ends 517 of the guide4 frame,fthereby Y.

"trough andinto the channel 65.

locking the latter tothe handles. The device ,is now in the position shown in F 1g. 5. It will be ,noted that the wheel 23" may have been previously moved against the bottom of the It, however, the arms 39 were made shorter, the wheel 23 would aiwaysbe in direct engagen'ient` with the bottoni of the trough, although Athat 't necessitate that the slot 48 be slightly Y hened.` New the operator breaks down he ham ts to return the :trame to substanhoiiicontal position and may continue :he iront rend or me device and cause thetroughto ride rearward over the wheel ,.23 and the roller 52. lt rwill be appreciated that when this occurs, the bottom ot' the trough elearstlie edges 62 of the plates 47 so t -ii-ictional. resistance is minimized. l. hen theftrough*reaches its .rear normal posit-ion, the hooks 63 engage the guide roller automatically and at the same time the pivot bar 50 drops into the recesses 5l and the links fall gravitationally and automatically engage with the rodV 59 in thenotches G1 as shown in F ig.,2. Since/the members 49 are b `reledl at their front ends as shown, these will also lcleainthe roller 52, thereby permitting the bottom ofthe trough to direct-ly rest 'on the edges 62 of the plates 47. The scoop (38 may now be thrown rearward and thede-` vice can be runalong the ground from place to place. In orderk to dump the contents of the trough it is merely necessary to upturn `the device by raising the ends oi" the handles, the-movement in this respect being entirely similar tothat which is practised in any conventional wheelbarrow.

rEhe movement shown in Fig. 6 can be dispensed. with, and the'trough merely manually' retracted by grasping the rear wall thereof.

ln Figs. land lis shown a' modification of the invention wherein the pivotal movement of the. body with respect'v tov the guide trame is eliminated. This may be accomplished in part by providing a guide frame T5 that pivotally Vmounted at 76 in proximity tothe extreme 4forward end or `toefot they handle 'trame 77'.r The latter has the usual wheelS mounted thereon at 79 andan underbraceSO to. cooperaft e with the wheel. rihe locking device 37, shown more vparticularly hereinbefore, isinounted onl the handles to function in a similar manner.

The guide frame 7 tural sections y'such as angle members 8l 'which are individually pivoted tothe handle 77 at 76.- rlhe trough 82 has a-ny'suitable guide members 813 to engage adjacent flanges or the angle members. .ln order to cause the handle 77 to .strongly act against thetrough in driving the same forwardainto a pile, lstop ele1nents84 are secured to the underside of the trough in position tof'be engaged by the torwardends or thehandles. These stop ele- .ng down on the ends26 of the handles to 5 `may consist of struc-.

l Ui

ments may be secured to a guide means 85 rthat peripherally engages the wheel 78 in a manner similar to member hereinbefore described. lVhile the angle members 7 5 may be disposed at their forward ends along the outside of the handles 77', yet they are adapted to be received at their rear ends between the said handles, it being understood that the members extend in parallelism to each other. Then thus received between the handle 77, the locking device 37 will readily function as aforesaid. The portions 86 at which the angle members are pivotally mounted may consist of projections or eXtensions that may be secured in any suitable manner to the said members. At the rear end of the body is a latch in t-he form of one or more hooks 87 that are adapted to automatically snap into engagement with the ends of the angle members 7 5 or with a cross brace that may be provided to connect the ends of the angle member together.

In operation, the trough 82 is positioned initially in a manner similar to -that'in Fig. 1. On release of the latching device 37 the guide frame 75 moves upward about the pivot 76 and simultaneously the latch 87 may be released, causing the trough 82 to move downward and thus serving to automatically accomplish the pivotal movement of the Yguide frame. The ends 77a of the handle 77 will now automatically engage the stops 84 so that the trough can be readily driven into a pile. The latch 87 may in this position merely ride freely over the guide frame. Thereafter the handles 77I are moved forwardly about the pivot 79 of the wheel and secured with the guide frame by the locking device 37. Y handles 77, the trough 82 moves rearwardly and readily rides over the wheel 78. It will be clearly apparent that the stops 84 are now out of engagement with the ends 77a of the handles. On reaching its extreme rearward position, the latch 87 automatically engages the rear end of the guide frame to lockV the trough. In order to dump the contents of the trough, the device is upturned in the usual manner and rests upon the front endV 77a of the handles.

The slope' of the front digging wall can in any case be varied to suit, and may be made much larger than that shown, and approxi-y mate an angle vof 40 with the plane 'of the bottonrof vthe trough. The bottom of the trouglrmay be shortened, when so increasing the slope of the digging wall. The scoop may be omitted, and substantially a full load nevertheless dug and loaded.

From the foregoing, it will be seen that there is provided a device which achieves the objects of this invention and accomplishes advantages of practical value. The body of the wheeled carrier is positioned on the earrnge se to be always ready'for immediat-e On breaking down on the use, whether it is desire of the operator to load or dump the device.

Manyembodiments may be made of the above invention, and many changes may be made in the embodiment above set forth. is to be understood that all matter hereinbefore set forth, or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.

It will be understood that suchterms as front,.rear, up, and derivatives and combinations therefrom a-re `used herein in an approximate, relative, and illustrative sense to clearly .define the invention, and not to limit the principles thereof.
