WHEELBARROW OR LIKE VHEEL.

Application filed March 19, 1925, Serial No. 16,841, and in Great Britain February 13, 1925.

This invention relates to wheelbarrow or like wheels wherein the wheel is provided with an axle which projects from either side, permitting it to engage lin the bearings provided on the barrow structure.

A primary object of the present invention is to provide a wheel with a live axle which can be readily detached for transport or storage'without the necessity of disconnecting the inner or hub ends of the spokes` so that the axle can be easily replaced forruse by an unskilled person, and without the necessity of reiitting the spokes.

A further object of the invention is to provide a construction for obtaining the above primary object which can be manufactured in the cheapest and most economical manner compatible with strength and durability, and to this end the use of cast n'ietal parts is dispensed with and a construction employing wrought or rolled metal parts is made use of.

A further particular object of the present invention is to provide an improved form of hub construction for the wheel which is formed from metal plates or members of not very great thickness, thereby simplifying manufacture, and yet which will provide a recess or socket for the axle of a substantial longitudinal dimension and thereby render the construction adapted to withstand stresses tending to twist the wheel laterally on the axle.

The essential features of the present invention are enumerated in the following claim, and a particular embodiment is illustrated by way of example in the accompanying drawings.

Referring to the drawings Figure 1 is a perspective view showing one form of wheel constructed in accordance with this invention.

Figure l is a perspective view showing the parts of the wheel separately.

Figure 3 is an end view in section.

In the construction illustrated, the rim 1 is made of metal which may be rolled to T section with its central iiange 2 upon the inner side.

The arms 3 of the Wheel are each made of two identical strips of metal riveted on either side of the iiang'e 2.

The inner ends of these arms 3 are attached by rivets 4C to a central disc 5 forming the middle part of the hub.

The hub is completed by two outer plates G detachably secured upon the sides of the inner ends of the strips 3.

rIhe central plate or disc 5 is provided with a rectangular hole 7 for receiving the central part 8 of the axle 9.`

The central part 8 of the axle 9 is formed with two opposite projections 10, the ends of which form external shoulders 11.

rlhe axle is placed in position with its central part 8 in the rectangular hole 7, and after it is in position the two plates 6 are secured upon the sides of the inner ends of the strips 3 by means of bolts 12.

The inner extremities or edges of the four pairs of arms or spokes are disposed flush with the edges of the rectangular hole 7 and thus form a socket adapted for receiving the axle 9 and strengthening the construction against lateral twisting of the wheel on the axle. The plates 6 further strengthen the construction, as well as serving to secure the axle against endwise movement by engaging the shoulders 11.

If required, one of the plates 6 may be permanently lixed or riveted in positio'n instead of making both plates detachable.

What I claim then is A wheel having spokes and a hub formed from metal strips and discs, the hub and spokes together forming an axle socket which is of a substantial length in relation to the individual thickness of said strips and discs, and means whereby the socket secures the axle against rotation and endwise movement in a manner permitting ready withdrawal of the axle without disconnecting the inner 'ends of the spokes.

In witness whereof I atlix my signature.

OLIVER HANCOGKS HAWLEY.
