Patented July 25, 1933 PATENT JACOB THOBDSEIBLOF KON'NERN, GERM'ANY TIPPABLE AND PORTABLE MIXING APPARATUS Application filed. October 3, 1931, Serial No. 566,695, and in Hungary May 21, 1931.

This invention relates to a tippable mixing apparatus, which is arranged portable or stationary, especially for mixing quantities of mortar, concrete, road making maartificial manures and the like.

The invention consists in producing a constructionally simple device, cheap to make and adapted to withstand rough treatment,

and which facilitates the charging and mixing of the materials in question, such as cement sand or the like, and also dumping of the finished mixed materials.

According to the invention the tippable frame of a stationary or portable mixing machine has two abutting pairs of bars bent at an angle, one pair of bars supporting the machine during the mixing, and the other during the emptying of the mixing vessel. This vessel is rotatably mounted around an axle extending from its bottom and mounted in a bearing and preferably supported on rollers or the like.

Owing to this construction the machine can be tilted into two different inclined positions, namely for mixing and for emptying the vessel.

For the purpose of facilitating intensive mixing, especially of muddy materials and gravities, the mixing vessel is provided with a removable insertion ring with mixing arms. Several embodiments of the invention are illustrated by way of example in the accompanying drawing in which:

Fig. 1 shows the apparatus in side elevation in position for transporting. 2 is a similar view showing paratus in position for mixing.

Fig. 3 shows in side elevation the apparatus in position for dumping.

Fig. i is a side elevation of a stationary tippable apparatus. a

Fig. 5 shows the insertion ring in perspective view. 7

A frame is composed of two longitudinal beams 10 extended to form handles 9 and supporting members 3, connected by suitable struts and transverse members. A pivot pin 1 is mounted on the frame. On this pin 1 the apsolid substances having different specific a mixing vessel 2 is rotatably mounted and provided with outwardly projecting handles 4. In order to relieve the pivot pin 1, the mixing vessel 2 is preferably also mounted on rollers arranged on the frame. In the portable construction an axle 8 and wheels 7 are fitted on the frame like a hand-cart, whereas in the stationary construction small wheels 3a may be arranged on the supporting members.

For the purpose of obtaining intensive mixing of the materials it is preferable, in the case of many materials, to provide the mixing vessel with an insertion ring 12 carrying stirring arms 13. This arrangement enables a uniform mixing without subsequent separation of materials of diiferent specific gravities which have a tendency, when being mixed without an insertion ring, of partly separating, in that the lighter and coarser materials roll to the top and the finer and heavier materials sink on to the bottom of the vessel. The struts or stirring arms, widened towards the upper end and fixed on the insertion ring, convey in upward direction the lighter material rolling forward during the rotation of the mixing vessel. This material. then drops into the middle or on to the bottom of the mixing vessel.

The operation of the portable construction is as follows:

The mixing vessel 2 is transported in the position, shown in Fig. 1. The frame is then brought into the position, shown in Fig. 2, after which the materials to be mixed are charged into the vessel, which is then rotated by means of the handles 4. Owing to the rotation of the mixing vessel, the materials to be mixed are lifted in the vessel, where they roll over, and consequently a falling, pouring and consequently intensive mixing movement is imparted to the materials.

When the mixing process is terminated,

the a ngaratus is returned into the position 9 illustrated in Fig. 1, and conveyed to the point of use. Here it is tipped into the position, shown in Fig. 3 so that the material can be emptied into receptacle 11 by slightly turning the mixing vessel.

shape from the periphery of said vessel adapted to enable the rotation of said vessel by hand.

2. A tippable mixing apparatus as specified in claim 1, comprising in combination with the vessel, a ring loosely inserted in said Vessel and downwardly projecting arms on said ring, bent towards the middle of the vessel adapted to intimately mix the contents of said vessel when said vessel is rotated.
