SPECIFICATION forming part of Letters Patent No. 399,723, dated March 19, 1889.

Application filed May 29, 1888. Serial No. 275,472. (No model.)

T0 66 1071,0121 it may concern:

Be it known that I, JOSEPH ANNIN, of Brooklyn, Kings county, New York, have invented certain new and useful Improvements in Me tallic \Vheelbarrows or Trucks, of which the following is a specification.

My invention relates to that class of barrows which are constructed with a sheet-metal tray mounted on two tubular frame-bars, between the front ends of which the wheel is journaled, while the rear and divergent ends of the bars form the handles of the barrow.

My improvement applies more especially to barrows of this kind which are constructed to dump sidewise, as is the case with the common canal or contractors barrows; and the object of my invention is to greatly strengthen the sheet-metal tray and enable it to better stand the strains of loading and dumping without buckling or tearing the sheet metal; and to this end my invention may be briefly stated to consist in strengtheningbands secured or riveted to the sheet-metal tray and extending longitudinally on the bottom thereof, at the center of the same, between the han dle-bars, and also at each d 11 mping side of the tray between the handle-bars and the edge of the tray, which bars impart great strength and rigidity to the tray at critical points without materially increasing its weight.

My invention also consists in some minor features in connection with the main feature above outlined, as hereinafter fully set forth and claimed.

In the drawingsannexed, Figure 1 represents a side elevation of my improved barrow; and Fig. 2 gives an end elevation thereof, with the handlebars cut off or in section close to the tray. Fig. 3 is an inverted plan view of the tray.

1n the drawings, A indicates the tray, B B the tubular frame or handle bars, and O the wheel of the barrow, which are formed, arranged, and connected in about the usual wellknown manner common to barrows of this class.

The tray A, as shown, is made of strong sheet-iron in a dished or flat hopper shape, which is lowest at the sides, as best seen in Figs. 1 and 2, to adapt the barrow to dump sidewise by tilting the barrow to one side in the well-known way. The end of; the hoppershaped tray next the wheel is the highest, as

shown best in. Fig. 1, to prevent the contents from fouling with the wheel in loading or dumping, and the opposite end of the tray near the handles is about one-third less in height than the wheel end, as shown in Figs. 1 and 2, which is about the usual shape adopted in this class of barrows. Now, upon the under side of the tray two strong metallic ribs or bars, 0 c, are bolted or riveted, which bars extend transversely on the tray, as shown, just at the angle where the high diverging ends of the tray spring from the dished middle, as well shown in Figs. 2 and 011 the ends of these bars 0 are secured the cast or malleable iron clips (Z d, (see Figs. 2 and 1,) in whiclrthe tubular frame-bars B B are received and held, as best seen in Fig. 2, which features require no further description, as they form no part of my present invention, but are of the usual construction and are clearly illustrated in the drawings. The tub ular bars B converge toward each other at the front end, on which the axle-boxes f f are clamped, as seen in Figs. 1 and 2, in which the wheel C is journaled in the usual manner, while the opposite or handle ends of the bars are diverged sufficient] y to permit the wor] man to stand between and grasp the handle ends in the usual manner, as will be understood from Figs. 1 and 2.

Referring to Figs 1 and 2, g are V-shaped metal legs secured to the front and rear clips cl (1, on which the barrow is supported when at rest, and h is a brace between the legs, all of which are of substantially the usual eonstruction.

Referring again to Figs. 1, 2, and 3, it will be noted that the tray is bound with a marginal band of metal, a, which extends all around the same and is dulybolted or riveted thereto, and thus greatly stiifens the sheetmetal tray and strengthens or arms its otherwise weak and vulnerable edge against the various shocks, strains, and frictions of loading and dumping. It will therefore be seen that the handlebars B B, underlying the tray about half-way between its middle and the dumping sides or edges, together with the marginal binding 2' on the edges, act to support and stiffen the tray at important points;

and heretofore these were the only points of the tray which were specially supported or stiffened. According to my improvement, however, I further brace and strengthen the tray by a strong central or spinal bar, 7c,running longitudinally under the tray midway between the handle-bars, and also by two side braces or ribbars, m m, half-way between the handle-bars and 'the marginal bands 71 on the dumping-edges. These bars 70 m are of course bent to conform to the parts of the tray on which they are superposed and are firmly bolted or riveted thereto, as shown. The transverse clip-bars c are bent at the middle to overlie the central or spinal bar, 7c, and are riveted at the point of crossing, as shown best in Fig. 3, thus forming points of great strength under the bottom of the barrow. The marginal binding-bar is also bent to overlie the ends of the central and side bars, 70 m m, and is rivited at the overlapping points, thus greatly strengthening the tray at several points around the rim. It will now be seen that the middle bar, it, acts as. a spine or backbone to the middle of the bottom of the tray midway between the handle-bars at a point which requires special strength, but which has been heretofore comparatively weak and not specially strengthened or supported; but it will be seen that the spinal brace or bar 70 will enable the tray to effectually resist the central crushing and buckling strain of an even load when the barrow is filled and moved,'while the side-braces, m m, will enable the tray to effectually resist the strains of this load when suddenly shifted to the side and (lumped, and thus prevent the tray from becoming buckled or strained on the dumping-edges by the continued shocks of such shifts and dumps. On the other hand, in the old construction, where the sheet metal is left entirely unsupported between the marginal band on the dumping-edge and bars B B, the metal is very likely to become buckled and strained and soon worn out at these weak and critical points by the continued shocks and strains of dumping. It therefore follows that by means of the central and side re-enforcing bars, k m m, I can actually make the tray of sheet metal of less than the usual thickness, and yet produce a tray of much greater strength, stiffness, and durability without increasing the weight of the barrow, and at little or no greater cost, which are important considerations.

hat I claim is 1. In a wheelbarrow or truck of substantially the described kind, the combination, with a sheet-metal tray, A, mounted on handle-bars B and adapted to dump sidewise, of the longitudinal brace-bars m m, fixed to the bottom of the tray on the dumping sides between the handle-bars and its dumping edge, substantially as shown and described.

2. A metallic wheelbarrow-tray, A, formed with the central longitudinal bar, it, and longitudinal side-bars, m m, substantially as and for the purpose set forth.

3. The metallic wheelborrow-tray, A, formed with the marginal binding 2', central longitudinal brace-bar, 7c, and side longitudinal brace-bars, on m, arranged 011 the under side of the tray and operating substantially as and for the purpose set forth.

4. The combination, with the tray of a wheelbarrow, of the central longitudinal bar, 70, and the transverse clip-bars c c, the one bent to overlap the other, substantially as shown and described.

5. In a metallic wheelbarrow, the combination, with the sheet-metal tray A, of the handle-bars B B, secured to and underlying the same, the marginal binding 7 the central bar, 7t, secured longitudinally to the tray between the handle-bars and the side bars, on m, secured to the dumping sides of the tray between the marginal band and the handle-bars, substantially as herein shown and described.
