  • a removable partition in the container facilitates manual turning of the container by dividing the load.
  • References Cited I 10 Claims, 5 Drawing Figures UNITED STATES PATENTS 1,920,025 7/1933 Thordsen ..259/ 176 PMENIED FEB I 1972 sumaurz PATENIEB FEB I I972 MULTIPURPOSE CART AND MIXER This invention relates to carts, and particularly to simple mixers for concrete or other materials which may be moved on wheels by an operator.
  • the primary object of this invention is the provision of a multipurpose cart suitable for mixing materials such as concrete, but also capable of functioning as a wheelbarrow, a spreader for liquid fertilizer, and for other purposes that will readily suggest themselves as the need may arise.
  • the cart of the invention has a frame equipped with at least three-point support by suitable members mounted on the frame in a position in which they are adapted simultaneously to engage a horizontal surface. At least one of the support members is a wheel.
  • the frame carries a bearing arrangement on which a trough member is mounted for rotation about an axis which normally extends horizontally.
  • Operating means are provided for tuming the trough member about the bearing axis, and a substantially trough-shaped cover may be sealingly connected to the trough member in such a manner that they jointly enclose a cavity.
  • Handles on the frame permit the cart to be rolled on an approximately horizontal surface by means of its wheel or wheels.
  • FIG. I shows the frame of a cart of the invention without the mixing container in a perspective view
  • FIG. 2 shows the frame of FIG. 1 assembled with the open container in a view corresponding to that of FIG. 1;
  • FIG. 3 illustrates the fully assembled cart with its container sealed in a view analogous to those of FIGS. 1 and 2;
  • FIG. 4 shows a divider insert for the container of the cart in a perspective view
  • FIG. 5 illustrates an open'container similar to that shown in FIGS. 2 and 3 having the divider of FIG. 4 installed therein.
  • the frame common to the several illustrated carts of the invention consists essentially of three welded assemblies of steel tubing.
  • a handle assembly 1 is approximately H-shaped and upright in the normal operating position of the cart except for the upper ends of the two parallel side members which are bent into a common horizontal plane and carry plastic handles 1'.
  • the lower ends of the parallel handle assembly members are telescopically received in respective upright supporting columns 2 of the two identical side assemblies of the frame and secured in a desired vertical position by setscrews 2.
  • the two members 3 carry respective bearings 5 whose shells are split and hingedly connected.
  • the bearings 5 are open and empty.
  • the left side member 3 also carries a bearing block 6 the purpose of which will presently become apparent.
  • the crossbar of the handle assembly l carries a rod 7 slidable on the crossbar in the direction of cart movement in a sleeve 7' welded to the crossbar.
  • the rear end of the rod 7 is perpendicularly bent to form a grip which is fastened to the handle assembly 1 by a chain 7!! 7
  • the cart includes a split mixing hopper whose practically identical halves 8, 9 are troughs releasably connected by hinges 10 in the open and,
  • Each trough 8, 9 consists of a plastic shell 13 and a rigid, rectangular steel frame 14 about the open rim of the shell.
  • a bail handle 12 is fixedly fastened to the frame 14 of each trough 8, 9. the handles l2 projecting in opposite horizontal directions from the two frames 14 on the closed hopper.
  • a shaft 15 is transversely fastened in opposite ends of the troughs 8, 9, the shaft in the trough 9 not being visible in the drawing.
  • Each shaft 15 carries a blade 16 and two perpendicular rods 17 for breaking up lumps in the material being mixed.
  • a resilient gasket 18 on the trough 8 seals the hopper when the trough 8 is swung down as a cover on the trough 9.
  • Trunnions 19, 20 project from the frame 14 of the trough 9 and are journaled in the two bearings 5, thereby permitting the hopper to be turned about the common axis of the bearings 5 by means of the handles 12 for mixing its contents. If the load is too heavy to permit manual rotation of the hopper 8, 9 by means of the handles 12, a sprocket 21 may be mounted on the trunnion 20, a crank 23 carrying "a small sprocket 24 on the bearing block 6, and a link chain 25 trained over the sprockets 21, 24, as is shown in FIG. 3.
  • the rod 7 is inserted into the tubular member 22 of the handle 12 on the trough 8 which is rearwardly open in the trough position seen in FIGS. 2 and 3, thereby preventing rotation of the hopper about the trunnion axis.
  • the trough 8 serves as a cover during operation of the cart as a wheelbarrow or may be removed after disengagement of the hinges 10.
  • the cart When the cart is to be stored for an extended period, its bulk may be reduced greatly by removing the hopper 8, 9 from the frame, releasing the wheels 4 from the forks 4' by loosening wingnuts 4" on the wheel shafts, and withdrawing the handle assembly from the columns 2.
  • the three frame assemblies and the wheels then can be fitted in the closed hopper.
  • it may also be convenient to remove the wheels 4 and to support the hopper on the forks 4' and the columns 2.
  • the columns 2 When the cart is moved, the columns 2 are lifted from the ground by means of the handles 1 and the wheels 4 roll on the ground.
  • the interior of the trough 8 may be cleaned by a stream of water from a hose, and the water collecting in the trough 9 and water used for cleaning the latter trough may be released by removing a threaded plug 30 from the trough 9. If the plug is replaced by a distributor or nozzle, not shown, the cart may also be used as a spreader for liquid fertilizer, herbicides, and like liquids.
  • the partition is a plate 26 having the approximate shape of a regular hexagon and corresponding to the upright cross section of the closed hopper through the trunnion axis.
  • Four approximately U- shaped positioning bars 27 project in pairs from opposite faces of the plate 26.
  • the bars 27 of each pair are connected by a straight flat bar 28 which is useful in breaking up lumps in the mixed material in a manner similar to the elements mounted on the shaft 15 in FIG. 2.
  • FIG. 5 shows two hingedly connected troughs 8, 9 substantially identical with the hopper halves seen in FIG. 2, and the partition assembly of FIG. 4 mounted in the trough 9.
  • the cavity is filled with material to less than one-half of its capacity.
  • the entire material being mixed is located below the trunnion axis at all times. With the partition plate 26, ap proximately one-half of the load can be held above the trunnion axis during about one-half of each hopper revolution, thereby facilitating the turning ofthe hopper.
  • the troughs 8, 9 shown in FIG. are equipped with modified bail handles 2) connecting the longer sides of each frame 14 near the short sides and enveloping and protecting the shells 13.
  • the hopper 8, 9 is supported on the ground in four points by the two columns 2 and the two wheels 4.
  • three-point support may be sufficient, and a single wheel may be mounted on a shaft (not shown) connecting the forks 4' in a manner conventional in wheelbarrows if the cart does not carry very heavy loads.
  • the wheelbase of the cart may also be reduced by interchanging the side assemblies of the frame because the wheel 4 in each side assembly, as shown in FIGS. 1 to 3, is axially offset from the common plane of the side member 3 and the column 2 in a direction away from the other wheel.
  • a single cart of this invention is versatile enough to be useful in these and other applications for which some of the illustrated elements may be removed from the frame.
  • the troughs 8, 9, for example, when not needed on the cart, have obvious other uses singly or connected by the hinges l0, and all other elements of the cart may be stored in a very small space. Minor modifications may further expand the field of application for the cart.
  • a multipurpose cart comprising, in combination:
  • a trough member mounted on said bearing means for rotation about a normally horizontally extending axis;
  • sealing means for sealingly connecting said cover member to said trough member in such a manner that the trou h member and the cover member jointly enclose a ca during said rotation of the trough member;
  • a cart as set forth in claim 2, wherein said scaling in: include hinge means connecting said trough member and cover member for pivotal movement between an open and a sealed condition of said cavity, and latch means engageabic for connecting said trough member and said cover member and for thereby preventing said pivoting movement when said cavity is in the sealed condition.
  • said operating means include a handle member on at least one member of the pair constituted by said trough member and said cover member.
