Nrren STATES CHARLES D. SPALDING, OF RICE LAKE, \VISOONSIN.
fiPIBCIPIQATION forming part of Letters Patent No. 385,381, dated July 3, 1888.
Application filed April 7, 1888. Serial'No. 269,940. (No model.)
To all whom it may concern:
Be it known that LOHARLEsD. SPALDING, a citizen of the United States, residing at Rice Lake, in the county of Barron and State of "Wisconsin, have invented certain new and useful Improvements in \Vheelbarrows; and I do declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it ap pertains to make and use thesaine, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.
My invention relates to certain new and useful improvements in wheelbarrows; and it consists in a frame having an end shaft provided with adjustable wheels.
The object of my invention is the construction of a wheelbarrow that will-run steady and obviate the tilting motion usually experienced in handling a wheelbarrow with a single bearing-wheel secured in the center of the axle. I attain this object by means of the peculiar construction and arrangement of the various parts, which will be hereinafter described and claimed, reference being had to the drawings accompanying this application and forming part of the same, in which Figure l is a perspective view of my invention with the wheels separated and with one sideboard removed and the end-board partly broken away. Fig. 2 is a plan view of the frame of the same, showing the wheels placed close together. -Fig. 3 is a detail view in sec tion through one of the wheels and its retaining-collar.
Similar letters refer to like parts throughout the drawings.
Referring to the drawings, A represents a framehaving curvedhandle extensions B,their opposite ends provided with metal straps C, that are formed at their outer ends with journal-openings a, to receive the ends of shaft D. The center of shaft D is provided with a circular stoppiece, b, secured rigidly in place by welding or bolt. On each side of stoppiece 6 a bearingwheel, E, is loosely held at any desired point on said shaft by loose bands e, that are held in place by set-screws e. A
hook-slide, e, is secured to the inner face of each band 6, that is formed to engage with a groove in the outer collar of each wheel-hub to hold said wheel to said band or collar, whereby when the band (1 on either side is moved along the axle or shaft D the wheels E are also moved and held where thebands e are secured by the set-screws e, permitting the wheels E to revolve in either direction freely, the purpose of this construction being to give any desired bearing within the limit of the shaft D. The usual end standards are placed in the frame A to support the handles and frame when not moving.
It will be readily seen that in turning round the wheels move in opposite directions, giving steadiness to the frame and case to the operator.
Having described my invention,whatlclaim 1s- As a new article of manufacture, the wheelbarrow A, having the usual handles, 13, terminating forwardlyiu the bearing-shaft D,whereon two wheels, E, are adjustably mounted by reason of the collar 6, having a bayonet-joint, c and a set-screw, 0', whereby the distance between said wheels is variable and their directions of motions in turning opposite to each other.
In testimony whereof I affix my signature in presence of two witnesses.
