Concrete cart

Application filed December 8, 1920. Serial No. 429,217.

To all whom it may concern:

Be it known that I, Arthur P. Robinson, a citizen of the United States, and a resident of the city of Plainfield, in the county of 6 Union, State of New Jersey, have invented certain new and useful Improvements in Concrete Carts, of which the following is a specification.

The improvements relate to carts adapted 10 -to be operated by hand and to be used for conveying plastic concrete and similar substances.

Among the objects of the improvements are to produce a strong and effective cart 15 of the character referred to, of simple and inexpensive construction which can be made principally of sheet metal stamped or otherwise formed, and to so construct the parts that they may, when not assembled, be 20 nested and otherwise placed together in a relatively small and compact space, for transportation, storage, and other purposes.

Carts of this character are used to receive concrete when discharged from a mixing de25 vice, and are ordinarily pushed by hand to the place where the concrete is to be placed and there dumped. In an ordinary building or other concrete operation a number of these carts are employed, and when the 30 work has been completed it is often necessary to store the carts and other apparatus or transport them to another place. The manufacturer also finds it advantageous to make up the parts in considerable quantities 35 and to keep these parts in stock for the filling of orders, and when orders are received to ship them unassembled to the purchaser. It is also necessary for the user to ship carts to a distant point to be used on another job, 40 and by forming the parts of the cart so that they can be placed together compactly for this purpose a great saving is effected. The carts are also subjected at times to rough usage, and parts frequently become bent or 45 broken. Therefore by making the carts of interchangeable parts, and having each part so constructed and arranged that it may be easily removed and replaced by a similar part delay on account of needed repairs is 50 avoided, since it is only necessary for the user to keep on hand one or more extra parts to provide against such a contingency.

The improvements are illustrated in the accompanying drawings, in which Figure 1 is a perspective view of a concrete cart em- 55 bodying the said improvements; Figure 2 is a front view of the same with a portion of the body broken away and the hub and one wheel thereof in vertical plane with the axle shown in vertical cross-section at one 60 side; Figure 3 is an enlarged detail in side elevation of one of the axle collars of the cart; Figure 4 is a vertical section of one of the wheel hubs; Figure 5 is a front elevation of four bodies and handles nested, with the 65 outer one broken away at one side. .,

The body 1 is formed of a continuous H piece of sheet metal pressed or otherwise formed into a bucket having downwardly inclined sides and ends, the front end having 70 a greater incline than the sides or the other end so that the contents may be easily dumped by raising the handle. Around two sides and front of the upper edge of this bucket 1 on the outside extends a band of 75 sheet metal 2 terminating in the arms 3 projecting rearwardly therefrom and connected at their outer ends- by the handle 4. This band is secured to the top of the bucket by means of rivets 5, and across the back edge 80 thereof and secured' to both bucket and extending arms 3 by means of rivets is a cross strip 6 having, ends 7 turned and placed against the said arms. The handle 4 is secured to the extremities of the arms 3 by 35 means of a bolt 8 extending therethrough. The parts thus described when once made may remain intact, and, as shown in Figure 5, may be nested by placing one bucket inside another. 90

The hubs of the wheels consist of a tubular portion 12, annular flange 13 riveted to the central opening of the disk 9 and webs 14 connecting the flange and tubular portion. The axle 15 extends through this hub 95 and is secured by means of cotter pins 16.

Riveted to each side of the bucket 1 and on the outside thereof is a plate 17 extending from the under side of the strip 2 downwardly, and having a collar 18 integral 100 therewith registering with a hole in the bucket. The axle extends through these collars and through the bucket and is fixed thereto by means of a pin 19 extending through the outer part of the collar and the 105 axle. By this construction the walls of the bucket are greatly strengthened, and the stresses and strains transmitted through the χ, δ as, 4®® axle distributed to the plat® 17 and the selvage strip 2.

In assembling a cart it is only necessary to place the axle in position and secure it 6 by the pins 19, then pass the hubs over the ends thereof and secure them by means of the pins 16. A washer 20 is provided between the pin and the outer end of the hub.
