BERNARD L. LONG, OF MOUNT LEBANON, PENNSYLVANIA.

DUMPING-WHEELBARROW.

To all whom it may concern Be it known that I, BERNARD L. LONG, a resident of Mount Lebanon, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Dumping-lVheelbarrows, of which the following is a specification.

This invention relates to wheel barrows.

The object of the invention is to provide a construction of the character referred to in which the body or hopper of the barrow or cart is movably mounted upon pivots, or other means upon the frame, in such man ner that it may be tilted or moved to dump its load at any desired place, without swinging or lifting of the main frame.

The invention consists in the construction and arrangement of parts hereinafter described and claimed, and illustrated in the drawings in which Figure 1 is a side view of one embodiment of my invention, the body or hopper being shown in its normal position; Fig. 2 is a similar view, showing the parts in position for dumping of the load; Fig. 3 is a top view of the frame, the body or hopper being removed therefrom to show details of construction; Fig. a is a detail cross sectional view, showing the yoke connection between the body and frame; Fig. 5 is a detail cross sectional view on the line 5-5, Fig. 8, and Fig. 6 is a detail view of a modified form of the invention.

I have shown my invention as applied to an ordinary wheel barrow having a main frame 1 and a single wheel 2. mounted at the forward end thereof, handles 3 being provided at the rear end of the frame for lifting the wheel barrow as is usual. Mounted upon the upper portion of the frame is a body or hopper 4; which may be of any desired shape or configuration and adapted to receive the load. The proportions and lines of this body or hopper, as will be obvious, vary with the character of the load and its weight, and as shown, it is shallow and of some breadth and is particularly adapted to receive loads of concrete, cement, plaster, mortar or other plastic ingredients.

The main frame 1 of the device illustrated is formed of a single, long, fiat strip of commercial iron or steel having a peculiar configuration. At the forward end it is bent into U-shape to provide arms 5 spanning the wheel 2 and to which are firmly riveted Specification of Letters Patent.

or otherwise secured, lugs or projections 6, providing a means of attachment for the axle or shaft 7 upon which the wheel 2 is mounted. Preferably, the wheel 2 and its axle and attached parts are formed of pressed steel riveted or bolted together in the ordinary manner. If desired, however, a wooden wheel of ordinary construction may be used. At the ends of the legs 5 of the U-shaped portion of the main frame, the latter is bent outwardly as at S and then inwardly at 9, continuing longitudinally of the barrow to form a pair of oppositely disposed bottom members 10 which, as illur= t-rated in Fig. 1, are twisted midway of their length and at their rearward ends are bent downwardly into loops 11 of round configuration which form the ends of the legs or props for supporting the barrow. These legs are formed in the manner stated to provide smooth surfaces for contacting with the ground or other support and obviating the presence of sharp corners or points which dig into the ground and prevent easy sliding of the barrow along the same while the legs are in contact therewith. The frame 1 is bent upwardly from the loops 11 to form the rear legs 12, at the upper ends of which itis bent into substantially hori zontal members 17 which extend forwardly and are twisted near the rear legs 1.2, at 13, to bring the strap into a vertical plane, in such manner that its forward ends may be attached at 14 to the forward portion of the bottom members 10. As illustrated in Fig. 3, a pair of diagonal braces 15 are provided to more rigidly secure and hold the parts of the frame together. These are riveted, bolted or otherwise secured together, as at 16, at their central portions, and each diagonal brace is secured at its ends to one of the lower frame members 10 and to the opposite upper frame member 17 as illustrated.

Fig. 4 illustrates in cross section the joint formed at the point where the upper frame members 17 are secured to the lower frame members 10. At these points are also pivotally secured the ends of the downwardly projecting arms 18 of a U-shaped yoke or supporting member 19. In the form shown in Fig. 4, the yoke 19 comprises a bar or rod having its ends bent downwardly and flattened to form the arms 18 and the horizontal cylindrical member 20 of which passes through apertures in a plurality of clips or lugs 20 securely riveted to the under surface of the forward portion of the body 4:, three such clips being shown. The construction described permits of oscillation of the body 4 upon the shaft 20 as a pivot. The upper member 17 of the frame and the lower member 10 thereof are secured together and to the legs 18 of the yoke-19 by a bolt or rivet 21 passing through alined apertures in these members. As illustrated, a thin washer or other member 22 is provided between the frame member 10 and the yoke 19 to slightly separate these parts and permit tilting or swinging of the frame member 19 upon the oppositely disposed bolts or other members 21 as pivots.

In Fig. 6 I have illustrated a modified form of the invention in which the yoke 19 is formed of a flat strip of metal having legs pivoted upon the bolts 21, as before, and upon the upper horizontal member of which is provided a lug or projection 40 upon which the body 4 of the barrow is supported at its forward end. A saddle 36 is rigidly secured to the under surface of the body 4, its arms 37 being disposed one on each side of the lug 10, and a pivot pin or bolt 35 is provided passing through the arms 37 and lug 10 to permit of oscillation of the body 1 upon the yoke 19.

The handle members 3, hereinabove referred to, are not integral portions of the frame nor are they rigidly secured thereto, as in prior constructions of wheel barrow of which I am aware. As illustrated, these handles are in the form of levers, each pivot-ally secured to the main frame 1 upon a cylindrical shaft or rod 25 projecting horizontally across the frame and having reduced ends 2 1 which pass through apertures in the upper frame members 17 and through a rectangular enlargement 27 of the handle members 3 and are threaded at their extreme end portions. Nuts 25 are provided on the outer ends of the reduced portions 2-1 of the shaft 23 to secure the parts in place, and thin washers 26 are provided between the enlargements 27 and the frame members 17 to reduce the friction at these points. At the forward ends of handle levers 3 is a U- shaped yoke or body member 29, having arms 28, the upper horizontal portion of which is illustrated in Fig. 3 and which is securely riveted or otherwise secured to the bottom of the body or hopper4 at a number of points. It will be understood that the yoke 29 is so secured to the body of hopper 1 as to be practically integral therewith in operation. At the rear-end of the body or hopper 1 downwardly projecting lugs 30 are provided, one at each side of the body. These lugs are of L-shape and have horizontal legs which are securely riveted to the body and vertical legs which project downwardly outside of the handles 3 when the body is in its normal position, as illustrated in Fig. 1. Preferably, the vertical legs 31 will be slightly inclined outwardly and downwardly in such manner as to assist in bringing the body or hopper to proper position upon the frame as it is lowered.

Securely riveted to the rear ends of the upper members 17 of the frame are L-shaped lugs 32 having outwardly projecting arms 33 for engagement by the handle members 3, for lifting the wheel barrow as an entirety and moving the same upon its wheel 2 in the ordinary manner. Obviously, if desired, these lugs may be mounted directly upon the handle members and project inwardly to engage the lower faces of the upper frame members 17. It is preferred to provide a brace 33 extending across between the oppositely disposed handle members 3 to hold the same rigidly in position with reference to each other and prevent their spreading apart, but this brace is not necessary and may be omitted, if desired. The brace 33 may be of any form or construction and is illustrated as a shaft bolted or otherwise secured to each of the handle members 3.

The construction and operation of my improved wheel barrow will be obvious from the foregoing description taken in connection with the accompanying drawings. Normally, the parts will occupy the positions illustrated in Fig. 1 and the barrow may be wheeled around and brought into any desired position for receiving its load, which will be placed in the body or hopper 1- as usual. The barrow having been loaded, it may be wheeled or moved to any desired position for dumping of the contents. Under these circumstances the barrow is used in the ordinary manner, that is, by grasping each of the handle members 3 with the hands and'lifting the same and trundling the barrow upon the single wheel 2. At this time, the frame acts as if it were composed of rigid or integral parts, by reason of the fact that the handle members 3 are pivoted to the main frame upon the ends of the shaft 23 and engage the arms 33 of the lugs 32 secured to the main fralne.

In the use of wheel barrows, as the same are ordinarily constructed with rigid frames and with no construction which adapts them for mechanical dumping of the load, it is customary to wheel the barrow up to the position where it is desired to dump its con tents, and lift the frame upon the axle of the wheelas a pivot until the end of the U- .shaped member 5 illustrated engages with the ground, when the barrow is tilted sidewise andits contents dumped from the side of the hopper. It is found in practice that in using wheel barrows in the manner stated, it is diflicult to discharge the load in the downwardly projecting lugs 20 or 36 precisely the place where it is wanted. Frequently, as the body of the barrow is llfted, the forward end of the same will roll rearwardly upon the wheel and the barrow will overturn, dropping its entire contents before they reach the delivery spot. In other cases, the method of side discharge being rather uncertain, the contents of the barrow are dumped outside of the area where they are desired. With my improved construction the wheel barrow is brought up to the delivery spot endwise and is halted in proper position with its legs 11 on the ground, the wheel 2 being brought up as close to the desired point of discharge as is possible under the circumstances. The operator then bears down upon the oppositely disposed handle members 3, thus tilting or oscillating the same about the shaft 23 as a pivot. This causes the forward ends of the handle members to rise and since the latter are piovtally connected to the lower ends of the legs 28 of the U-shaped yoke, the latter rises and lifts the body or hoppers from the fixed frame. The forward end of the body or hopper 4, as described, is pivotally secured to the upper horizontal member 20 of the U-shaped yoke 19, the arms 18 of the latter being pivoted to the frame upon the bolts or rivets 21. Consequently the forward end of the hopper cannot rise and must swing forwardly upon the bolts or rivets 21 as pivots. The pivots 35 and 20 are provided to give slight play between the yoke or supporting member and the body of the barrow and permits the same to swing. As will be obvious, as the body or hopper 4 is raised, its bottom surface assumes the inclined position shown in Fig. 2 and the entire contents of the wheel barrow slide forwardly out of the forward mouth or shovellike end of the body or hopper.

The barrow as a whole is simply constructed and for the most part its members are formed of commercial iron which may be had in various shapes and sizes. The main frame is formed of a single long fiat strap of steel or iron, as preferred, and the braces 15 are likewise constructed. The frame is securely riveted together and the body or hopper is preferably pressed into shape from a single plate or sheet of metal, having the lugs 30, frame member 29 and securely riveted thereto.

I desire it to be understood that my invention is not confined to wheel barrows having a single wheel. I have illustrated such an embodiment of my invention in the drawings but it will be obvious that if de-' sired, more than one wheel may be provided upon which the barrow may be moved. Moreover, instead of dumping forwardly, the body of the barrow may be pivotally mounted in such manner as to dump sidewise. All such modifications, I consider within the scope of my invention. Furthermore, although I have described and illustrated the frame, body and other parts of my wheel barrow as made of metal I wish it understood that the same, or any of the various parts thereof, may be made of wood or other material, if desired.
