including limprovedineans permitting the ''Wheelbarr'ow to 'be u's e'd in. an initial run along the ground for piling up the material to be loaded. 1

- Another object of. the invention is the pro- "vision of a"'de'vice of thenature set .forth 15 havingimprloved means facilitating the run aforesaid and operating as a. restxfor the wheelbarrow, in dumping the load.

A' further object of the invention is to produce a Construction of the type specifiedin Whiclf the body of. the wheelbarrow is movable with its digging wall into comparatively close 'proiiimityfto the grou'nd 'or' base of the pi'leff or thepurpose set forth. I Q'Other obje'cts will'inpart be evidentl and 'in p'art pointed {out hereinafter.

7 "Generally described, the invention includes a loading wheelbarrow comprising frame and a body thereonmovable like ascoep. The'whe'elbarrow is moved into upright posi- --tion, "and'the body swung about, a rear pivot away from'the'fr'afme. Thesaidfframe-rests on auxiliary wheels, permitting the wheelbarrow'in'this open or spread. position tobe run along the ground at the base of'the pile "for"gathering all: thefmaterial into the pile. Thereafter, the lfframe is broughtnp against the body, and the lat erlookedthereto, and the operatorgpivots the body forward and i1pward intothepile for digging action, aboutfthe. auxiliary 'and main wheels. of I the device, bringing the: Wheelbarrow into" nor-- "m1 horizontal position, On upturning the same into the. vertical, its'contents can be 5 Conveniently dumped.

The wheelbarrowcanalso be constructed to permit the body to moveforward over the, wheel, to increase the-movement of the dig- T tate the initial run.

teammate preferably the digging edge 1928. Serial No. 259,178. r

The body may execute part of'its downward movement over the Wheel, while 'theframe' of the wheelbarrow 1s being swung rearward back toward normal subsiantially horizontal position. Suitable 55 stop means limits this movement of the body, The body is then brought back to substantially horizontal position, and returned to normal position on the frame Where it is retained by other stop means.

J The invention herein described constitutes an improvement over that described in my application for filed Dec; 8, 1927 1 In the drawings:

minating at one end in the handles, 14, and

at the other end, having the Wheel 15 mount- -ed thereon. The side bars'may be reenforcingly connected together in any suitable manner, for example, by means of

cross braces

16 and 17. A usual rear support 18 may be employed. The rest for dumping consists of a movable-carrier 19, which may include the Wheels 20 mounted on the shaft 21, the lat ter being j ournaled in brackets 22 fixed to the frame 11.- x

The position of the body 12 with respect to the wheel 15 may be made to suit operating 106 moving off its seat on the edges dr ive actuator, whereby described.

12a of the said body is as far forward over the wheel as is consistent with convenience in the manipulation of the wheelbarrow, bearing in mind the general construction of the same and the length of the said handles. As shown in Fig. 3, the handles are thus substantially vertical in the upturned position of the wheelbarrow.

The frame includes a- 23 rigidly'secured to the of angle brackets 24 and 24M or many other feasible manner. The said plates extend in any suitable relation to one another, but are here shown parallel.

Fixed to the under side of the body 12 are the spaced supporting and reenforcing members 25. A pivot bar 26 passes throughthesc members and through the plates 23, so that the body 12 is swingable away from the frame 11. The members 25 have flanges, slidably engaging the said plates, as clearly shown in Fig. 5, thus affording lateral support to the body 12 in course of such movement.

The members 25 constitute guides in another sense also, being provided with the alined slots 27 toward the front ends of these members. Spanner bars 28 engage the guide members by means of follower pivot 29 movable in said slots. The other ends of the bars 28 are fixedly pivoted byrod 30 to brackets 31 rigidly secured to the frame 11.

A combined locking and drive member 32 of U-form is likewise pivotally mounted on 30. The member 32 comprises side arms 33, and a cross bar 34. The arms 33 have at their ends lugs 35 at opposite edges and spaced for engagement with their respective spann r bars 28. According to the position shown in Fig. 1, the member 32 being retained against unintended movemem by s1 ri:-g latch 36, so as to lie in out of the way position beneath the frame 11, the lugs 35 are then effective to lock the spanner bars a ainst pivotal movement, and preventpair of side plates side bars by means the body 12 from 37 of the ticular- .rned for plates 23. This is very impor ant 3 ly when the wheelbarrow is upt dumping.

In the position of member 32 saown in the said member is diseng and dropped till lugs "5 with the spanner bars 28. Due l 38 in the arms 33, the cross bar 34: is new C01 1 paratively low with respect to the ground. The cross bar reierred to now const utes a he operator, can are, hereinafter force the body 12 into the Since the side bars 13 of the frame extend at an angle toward each other, as in the usual construction of wheolbarrows, the mechanism herein is constructed with a iew to maintaining clearances for the moving parallel members. For example shown in Fig. 4, the spanner bars are in spaced relation to the guide members 25,

sleeves

39 and 40 being provided about the follower 29. Likewise, spacing sleeves 11 are used around pivot rod 30 and extending between brackets 31 and the spanner bars 28. It is contemplated, however, that the frame bars 13 referred to may be in parallelism for compactness and simplification in the operating mechanism while the handles 14: may be angularly related to one another.

In operation, the wheelbarrow is swung from its normal horizontal position, into the vertical, and member 32 released from its latch, thus permitting the body 12 to move outward of the frame 11 as shown in Fig. 2. The operator then takes hold of the frame at the members 18 and in as low a position as may be convenient, and runs the wheelbarrow along the ground. The body picks up the material in its path, lying at the edge of the pile, and this material heaps up into the body. Then the operator places a foot on the wheel 15, and, holding on to the members 18, pushes the frame back into normal position against the body 12, after which the member 32 is latched at 36, locking the body to the frame. Still keeping his foot on the wheel 15, the operator swings the wheelbarrow toward himself. Thus there is a powerful force exerted during the digging tending to drive the body forward and upward into the pile. The wheelbarrow rides along wheels 20 further into the pile, and swings from supporting position on said wheels to the main wheel 15. In order to dump the wheelbarrow, the same is swung upward in the usual manner onto the wheeled rest 19, while the latch 36 is effective. By this invention the largest size of body can be loaded with the heaviest and most reluctant material, if a man is placed at the pile to move material into the body with a shovel during the digging. The manipulation of the wheelbarrow is very rapid. Even where the operator works alone, and in the case of a diflicult material such as small coal, the body 12 does not load quite full, a very great saving of time and labor is effected, and a considerable number of wheelbarrows can be kept quickly moving. Where the material is lighter, a body of the largest size can be fully loaded by only one man.

If after the frame has been brought back against the body, and before the member 32 has been locked, it be desirable to take a further dig into the pile, the operator places his foot on the cross bar 34, and bears downward thereon, while holding the handles 14. The spanner bars 28 and the arms 33 act as continuous levers pivoting at 30 and driving the body 12 forward from the said frame. Rearward movementof the latter is effectively prevented by the forward componentof the force exerted by the operators foot. After such forward projection of the body 12, the
