Patented July 2, i912.

Be it known that I, JAoon A. LAwnnNon,

a citizen of the United States, and a resident. of Valparaiso, in the county of Porter and State of Indiana, have invented a new and Improved Wheelbarrow, of which' the following is a full,'clear, and exact description. c

v.The present invention relates to wheelbarrows and it has for its 'object to produce a wheelbarrow of simple form and so constructed that it may be quickly turned with-l in a limited space to change 'its course of travel and further to facilitate the dumplln of the barrow and to protect the wheel w ic supports the same.

-VA further object A,is to produce a wheelbarrow which is capable of having an uninterrupted forward dumpin movement and also'to protect and. strengt eny the hopperl more particularly at its forward end so as to receive and resist the blow and impactsincident to they dumping operation.

Reference is to be had to the accompany. ing drawing constituting a .part of this specification, in which similar characters of reference denote corresponding parts in all the views and in which- Figure 1 shows a central longitudinal section through a wheelbarrow embodying the invention; and Fig. 2 shows an under side plan View.

In the drawing, 1 indicates the hop er which may be constructed -of any suita le material, but which in the illustrated embodiment of theinvention, is constructed of .somesuitable sheet metal bent to form. It

v is provided with the outwardly flaring sides 2 and 3, and the outwardl flaring ends 4 and 5, 4 being the rear en and the forward end.

The hopperl is supported upon a single Wheel 6 connected to an axle 7 which turns n the brackets 8 upon the under portion of the hopper 1 and substantially centrally disposed withrelation to the bottom 9 of the hopper. The wheel 6 is considerably larger than is ordinarily used in such devices, and in order to have the load contained in the hopper as low as possible in order to lower the centernof gravity, there is provided in the bottom 9 of the hopper a recess or wheel housing 10 formed by the side plates 11, and a curved crown piece 12, the latter being secured at each of its ends as by the rivets 13 to the end walls 4 and 5 of the hopper 1.

, allel rods 17, and t beneath the rearend 4' oft e hopper in the form of the divergin brace rods 18 which This wheel housinglis of sufficient width to accommodate the' peripheryof the wheel and to permit its free revolution, and u on the inside of the hopper 1 forms somew at of a partition or division, so that if desired a smalll load of material upon one side may diier from av small `load upon the other. In order to strengthen the hopper, it is supported upon a frame work comprising a forward cross bar 14 Ywhich is bentat 1 5 and then downwardly forming the side braces 16 for the-frontend 5 of the ho per, From the side bare 16bit passes beneat the bottom 9 of the hoppler in the form of parence. asses vupwardly are continued upfward y beyond the top edge ofthe hopper and rearwardlyin the form of handles 19. This strengthening frame is secured to the hopper in any suitable or...

convenient manner as by means of staples 20 and 21 which embrace the members 'of th,

frameand pass through the hop er, being clenched or otherwise secured at t eir inner ends, also the side bars 17 beneath the'bottom 9 of the hopper pass through bearings 22 formed in'the4 brackets 8.

In order to support the hopper while being1oaded,it is provided with the supportin props 23 which may be conveniently forme as shown in the drawing of a single metallic rod having the centrally disposed cross bar 24 which is sup orted by brackets 25 mounted upon the rods 18, and thence bent downwardly and rearwardly as shown at 25 and by means of the large rounded bends 26 extended forward in the form of: braces 27, the ends of which are connected to the, brackets 8.

It will be noted that the position of the wheel with relation to the center of gravity of the hopper is such that the load will be distributed, the greater portion being at the rear of the axle, so that while being loaded and at rest, the hopper will be supported in the position shown in Fig. 1 by the props 23, also by reason of the relative position of the props 23 and the wheel, the wheelbarrow may be quickly rolled over the floor by giving it a push in the direction in which it 1s desired it shall go, and this without the necessity of raising or tilting the hopper upon its axle.

As shown in dotted lines in Fig. 1, the wheelbarrow may be quickly tilted or tipped ros I about whichtheloaded hop er moves. In 1V x v 'bracing @nd-'strengthening has connected a fward direction. When'tilted in a'rearward' direction,` theprops 23 actas the' fulcruins tilting' in a. forwardl direction, all that is necessary to do is to exert a sudden upward lift upon the handles 19 so as to throw the center of gravity to the front of the axle Y, whereupon a releasing of the handles 19 will cause the hopper of the barrow to assume the position as shown in dotted lines at the left in Fig. 1. It is of course understood that in this dumping operation the shock of the impact of the forward edge of the hoper against the ground will be borne by the grace rod 14 whlch will protect the body pf the hopper from damage and injury. It will be further noted that by placing the lwheel at substantially the central portion of the hopper, said Wheel/is in aprotected position and in such position that the manipulation of the wheelbarrow is materially facilitated.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A wheelbarrow comprising a hopper, a

wheel upon which said hopper is supported, located at the central part o the hopper and ofthe hopper,^and agrame for bracing and strengthening" said .hop er, ,comprising` la front "cross r and`v su stantially parallel said cross bar extending beneathfth'e hopper,-r upwardly incllm-adv at each end and provided with handles at their rear ends.

v2. A wheelbarrow comprising a hopper, a Y

wheel upon which saidhopper'is supported i located at the central part of the hopperand ofthe hopper, a frame for bracing andv strengthemng said hopper, comprising a m the'l A156113,"4

'sol

40 ,c .projecting at. its periphery within the body front cross bar and substantially parallel c bracing and strengthening bars connected toA sa'id cross bar extending beneath the hopper, upwardly inclined at each end and provided with handles at their rear endsfand a bent I rod forming, props for the hopper, secured thereto and extending rearwardly anddownwardly in an inclined direction.

In testimony whereof I have signed my name to this speciication'in the presence of two subscribing Witnesses.
