Description

Oct. 18, 1966 c. J. SEMAN Filed Sept. 25, 1964 MACHINE FOR MIXING INGREDIENTS INVENTOR.

COLMAN J. SEMAN United States Patent M 3,279,763 MACHINE FOR MIXING INGREDIENTS Colman J. Seman, 1409 Springlake Drive, Erie, Pa. Filed Sept. 25, 1964, Ser. No. 399,309 Claims. (Cl. 259-14) This invention relates to .a mixer and loader for concrete, cement products and other like loose materials and, more particularly, to an improved machine for mixing ingredients including loose materials such as cement products.

In the past there has been a problem of providing a machine to carry out an efiicient and fast mixing of ingredients such as loose mate-rials and cement products.

An object of this invention is to provide a device which can be used to carry out an eflicient, rapid and thorough mixing operation for loose materials such as cement products.

Another object of the invention is to provide a loading mechanism including a hopper which may be lifted easily and placed into position for loading a drum mixer.

Another object of the invention is to provide mixing drums situated in pairs on an axis of rotation, each drum having its central axis disposed at approximately 90 to the other so that they counter balance each other.

A further object of this invention is to provide a rapid system of mixing cement ingredients at a relatively low equipment cost.

Another object is to provide a tumbling type mixer for cement products.

Another object is to provide a process of mixing cement using a tumbling principle.

With the above and other objects in view, the present invention consists of the combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings and more particularly pointed out in the appended claims, it being understood that changes may be made in the form, size, proportions, and minor details of construction without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings:

FIG. 1 is a perspective view of the loader in the invention;

FIG. 2 is a perspective view of the loader and fork lift truck in combination; and

FIG. 3 is a perspective view of the machine elements according to the invention situated as in use.

Now with more particular reference to the drawings, the loader .10 is shown in FIG. 1 which is of a rectangular shape in cross section having a top opening ;11 in which the ingredients are received. A motor -12 which is located on the side is connected by means of a suitable drive to a riddling mechanism 11 or agitator which will sift the ingredients as they are placed in the opening 11 supported on the loader by means of links -111 and vibrated by a suitable vibrating mechanism (not shown). The motor may be fixed to the side of the loader above the lifting supports 15.

The lifting supports will be inclined upward from the rear of the loader 110 just above the bottom thereof and inclined upward and forward at an angle of about 45 These lifting supports 15 may be made of angle iron or some similar material and be provided with generally flat lower sides to accommodate the forks of a lifting truck.

The front of the loader will be provided with an unloading door 13 which will take up about half of the front end. Connected to the unloading door v13 which is hinged along the top will be a hopper door release bar 24 which when pulled by door release line 23 will unload the hopper. The front side of the loader has a rearward- =ly inclined front end 16 which extends from the unload- 3,279,763 Patented Oct. 18, 1966 .ing door 13 upwardly and to the load opening 11. Direct- -ly above end 16 and connected to the front of the opening '11 will be a bar spacer :17 which supports the door lifting arms .14. These arms 14 project forward parallel to the loader lifting supports 15 adjacent thereto.

In FIG. 2 a fork lift truck -18 is shown in position directly behind the loader .10 with the forks sliding in position under the loader lifting supports 15. As the truck 18 begins to lift the loader 10 it tilts the loader until the lifting supports 15 are in a horizontal position along with the door lifting arms 14. The loader :10 will be raised and moved into the position shown in FIG. 3.

In FIG. 3 two

cylindrical tanks

19 and 20 are shown with an axle 26 at their center supporting them. The drums are disposed at to each other and supported on the drum support frame 25 which is triangular in shape and has one frame member on each side of the drums .19 and 20. These drums will be supported at the top angle by axle 26 with suitable bearings. A motor 30 with a gear and drive chain 29 running to a sprocket 28 located between the drums rotate the drums and mix the ingredients therein.

The loader 10 and mixing drum 20 are shown in loading position in FIG. 3. As the fork lift truck 18 and loader :10 come in close proximity with the drums the fork lift lifts the loader until the door lift-ing arms 14 come in contact with the lugs 22 on the door 21. The lifting arms 14 will automatically lift the door into a perpendicular position thus allowing the unloading door 13 to be moved into position for releasing the contents from the loader 10 when door 13 is opened.

When the loader is in proper position for release the loader door release line 23 may be pulled by the operator and the door release bar will lift and open the door [13 thus releasing the contents into the cylinder drums. After the completion of this operation the loader 10 is removed by the fork lift truck 18 thus allowing the drum door 2-1 to close. The cover locks .27 will be swung into position and clamped and the cylinders will rotate so that the other cylinder drum -19 is ready for loading. The same procedure is repeated until both drums are loaded and ready for the rotation mix.

The mixer is then driven so that the contents tumble from end to end thereby agitating the materials therein. It has been discovered that successful mixing of cement powder can be accomplished when the drums are of such dimension that the length is approximately three times the diameter.

The foregoing detailed description has been given for clearness of understanding only, and no unnecessary limitations should be understood therefrom, for some modifications will be obvious to those skilled in the art.

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

1. A loader comprising a container generally rectangular in cross section and having an open top, and fiat sides and flat ends, and a flat bottom,

one end of said container being inclined upwardly and inwardly at an angle of approximately 45 and terminating at an edge of said top opening,

a lifting support rail attached to each side of said loader,
