W'HEELBARROW.

Specification of Letters Patent.

Application filed June 6, 1919, Serial No 302,261.

- Patented May 1920.

To all whom it may concern:

Be it known that 1, Jon Knirrxsxis, a

and useful Improvements in W heelbar rows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved wheelbarrow and the object thereof is to so improve the construction of the wheelbarrow as to obviate the necessity of a person wheeling the same carrying the main part of the load or bearing the burden thereof; to strengthen the construction of the wheelbarrow so as to permit it to better withstand rough usage; to facilitate turning or steering and to facilitate dumping without injuring the front supporting wheel, the device in its preferred embodiment being movable on three wheels.

With the. above objects and others in view as will appear as the specification proceeds,- the invention comprises certain novel combinations and arrangements of parts as will be hereinafter more particularly pointed out and claimed.

Reference is had to the accompanying drawings forming a part of this application, wherein like characters designate corresponding parts throughout the several views in which- Figure 1 is a side elevation of my improved wheelbarrow,

Fig. 2 is a plan view with the body re moved,

Fig. 3 is a detail longitudinal sectional view, and

Fig. 4 is a detailed transverse sectional view.

Referring to the drawings in detail, my improved wheelbarrow is shown as comprising a body 10 and handle bars 11 preferably made up of a section of pipe bent upon itself so that the bight portion 12 is disposed at the front end. The body 10 is secured to the side or handle bars 11 and for this purpose, there is secured against the bottom of the body at the front and back portions of the bottom thereof, transverse strips 13 which are bolted through the bottom as shown at 14. The ends of these strips are bent downwardly and inwardly in spaced relation to the intermediate portions so as to envelop the sides or handle bars,clamping means in the form of bolts 15-being disposed to con nect the spaced portions of the strips adjacent to the side bars so as to prevent shifting of one with respect to the other.

. Also secured by the clamping means 15 beneath the inwardly directed portions 16 are longitudinal bearing portions 17 which may be of a slight resilient nature, the latter having depending portions 18 to which. an axle 19 is rigidly secured as shown at 20. lVh'eels 21 are journaled on the spindle ends of the axle so as to bear the weight of the load contained in the body instead of necessitating that the operator bear the burden thereof. Extending contiguously with the bearing portions 17 are the rear ends of a substantially circular frame 22 suitably bolted or otherwise secured at its rear ends and connected by a cross brace 23. This frame extends for wardly of the body and is curved slightly upwardly at its forward end while in order to brace said frame to the front of the body, there is disposed a U-shaped brace- 24 bolted intermediately as shown at 25 to the inclined front portion of the body and having the extremities thereof bolted or otherwise secured to the frame as shown Extending longitudinally between the bearing portion 17 and connected to the cross brace 23 is a reinforcing spring and brace 27 curved downwardly adjacent to the bight portion 12 as shown at 28 and then connected to the securing means 26, while the free end thereof is curved downwardly and bent to provide a downwardly inclined U-shaped bearing 29 which receives in conjunction with the forward portion of the frame 22, a pivot 30 correspond ingly inclined. Between the forward portion of the frame 22 and the bottom portion of the bearing 29 is received a bearing block 31 mounted on the pivot 30 and having a fork 82 in which is journaled a wheel 33 forwardly of the bight portion 12 so as to sustain the load in connection with the rear wheels 21 and to facilitate steering of the wheelbarrow in either direction. The steering operation is effected preferably by tilting the wheelbarrow in the direction in which it is desired to turn, whence the steering wheel 33 will lag in the opposite direction due to the pivoting of its bearing, thus causing the wheelbarrow to turn. Also, the frame 22 facilitates dumping as the Wheelbarrow may be rolled on'the frame when tilted on end or to either side,

for dumping the load from the body or scoop thereof,'without injury to the steering Wheel. It will also be obvious that a considerably greater load can be carried without unnecessary burden on the operator, by reason of the three-wheel support arranged as described.

What is claimed is 1-- v r l. A wheelbarrow comprising scoop body, handle bars comprising -a single section, of material bent upon itself beneath said body, strips bolted to thebottom of the body and having the ends thereof bent beneath said bars, clamping means connecting said ends with the intermediate portions of the strips, bearings beneath said bars and strips, an axle supported by said bearings at the rear portion of the body, wheels on said axle, a frame having a circular forwardportion and rear extremities in aline portion of said bearing block for movement within the frame. 7

2. A wheelbarrow comprising a body, handle-bars comprising a single section of material bentupon itself to meet the body, means connecting the receptacle with the handle bars, a wheel-carrying axle extending transversely beneath the handle bars, a frame having a circular forward portion and rear extremities secured beneath the handle bars, a cross brace connecting the rear extremities of the frame, a transverse brace extending across the head portion of the frame and arched upwardly for engage ment with said body, a longitudinally extending bracing strip having its rear end connected with the cross brace and carried forwardly and arched upwardly for engagement vwith the arch brace and having its forward end portion connected with the head and bent to provide a bearing, a block pivotally mounted in the bearing, and a wheel carried'by the block.

3. A wheelbarrow comprising abody, a supporting frame for the body including spaced side bars, a wheel-carrying axle extending transversely beneath the supporting frame, an open head positioned in front of said frame and havingarms extending rearwardly' and connected with the body supporting frame, a bracing arch extending transversely of the head and engaging said head, a longitudinally extending bracing arch reinforcing the transversely extending arch and having its forward end portion bent to provide a bearing extending beneath the head, a block pivotally mounted in the bearing for lateral pivotal movement, and a supporting wheeljournaled in the rear portion of the block.
