WH EELBARROW.

SPECIFICATION forming part of Letters Patent No. 404,789, dated June 4, 1889.

Application filed February 27, 1889. Serial No. 301,357. (No model.)

To all whom it may concern.-

Be it known that I, WVILBER E. KILBORN, a citizen of the United States of America, residing at Sidney, in the county of Shelby and State of Ohio, have invented certain new and useful Improvements in WVheelbarrows, of which the following is a specification, reference beinghad therein to the accompanying drawings.

My invention relates to an improvement in wheelbarrows, and has for its object a novel construction of the frame-work, whereby with metal of light weight I am enabled to produce a very light, strong, easily-constructed, and cheap frame for the support of the tray.

The invention will first be described in connection with the accompanying drawings, and then pointed out in the claims.

Figure 1 is a perspective View of a wheelbarrow embodying my invention. Fig. 2 is a perspective view of the frame-work alone.

In the drawings, A represents the tray, which maybe of any of the forms now in general use. Y

B is the wheel, whose hub 12 is rigidly secured on a sleeve b, which turns freely on the axle O, the ends of which are screw-threaded for the reception of nuts n. It is evident, however, that I am not restricted to the use of this form of wheel; but I prefer it for the reason that I am enabled to use the axle as a bolt to secure the front ends of the different parts of the frame together, thereby avoiding the use of separate bolts for that purpose.

D represents a yoke for s upportin g the front end of the tray. It may be made of two pieces of metal, but preferably of one. If of the latter, it is made by bending the middle portion of a piece of bar iron or steel into such shape as to conform to the contour of the tray, and turning the straight end portions at nearly a right angle thereto, so that when the middle portion of the yoke is bolted to the end of the tray the end portions will extend down to and pass over the ends of the axle, they being perforated for that purpose.

E represents the legs, each of which is formed integral with a handle F. These are made, preferably, of gas-pipe, a piece of pipe of suitable length being bent in such manner that the leg and handle will stand at proper angles with relation to each other. The pipe is flattened and otherwise shaped at its bend, so as to conform to the shape of the tray, to which it is firmly bolted or clamped, or secured by any of the ordinary methods of fastening.

The bottom of the tray between the yoke and the legs is firmly supported by means of two trusses G, one 011 each side, one end of each truss being bolted to the leg and the. other end passing over the end of the axle outside of the yoke. These trusses are formed from pieces of light bar iron or steel, twisted in the middle, so as to produce a broad surfacethrough which to pass bolts or rivets to secure them to the tray, and bent so that their ends will reach to the positions indicated.

The legs are stayed by means of a transverse brace H, the ends of which are bent so as to lap preferably around tothe outer sides of the legs, to which they are bolted, and 1011- gitudinal braces I, one on each side, leading from the axle back to the legs. Instead, however, of lapping the ends of the transverse brace around the outer sides of the legs, the brace may be shortened, so that its bent ends will abut against the inner sides of the legs.

On reference to the drawings it will be seen that the yoke, the truss, and the longitudinal brace are all held by one bolt on the axle, and that a single bolt secures the transverse brace, the truss, and the longitudinal brace to the leg.

The advantages of my improved framework will be apparent when it is considered that the trusses afford a great degree of strength notwithstanding the fact that they are of comparatively very light weight, that the yoke forms an effective support for the front end of the tray, and also permits the wheel to be set well under the tray, which is very desirable, and that the legs are each formed integral with a handle, resulting in a considerable saving of material, and also permitting of the attachment of a leg and a handle by a single set of bolts, rivets, or clamps.

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

1. In a wheelbarrow-frame, a bar-metal yoke for the support of the front end of the tray, said yoke being so shaped that its mid- IOC 3. A wheelbarrow-f1'a1ne comprising the trusses, the yoke, the legs, and the handles, each leg being formed integral with one of the handles, and the longitudinal and transverse braces, all constructed and combined substantially as described, and for the purposes stated.

In testimony whereof I affix my signature in presence of two witnesses.
