I Appli ation January 28, 94.8, Se ial. Ale- 1.7.66

\ '1 This invention relates constructional aggregates such as cemetitious materials and the like and; more particularly, to mixers adapted for association with and opera tion by conventional tractors. Concrete mixers heretofore available usually require a source of powerhaving a drive coupling with a rotary mixing container or drum. It is not uncommon for such devices to constitute self-contained units in the form of anginternal combustion engine or electric motor coupled-with a receptacle for agitating cemeti-tious mix and the like. Because of the relatively high initial and maintenance cost of such units, the average farmer cannotafiord to own such apparatus for exclusive use on his premises.- It is, therefore, one of the important objects 'Of the present. in vention to provide 'a'mixing device of extremely low cost and capable of being attached to any conventional tractor. r

Not only are presently avialable mixers relatively high in cost to the average .farmergbut they also introduce the difiiculty of requiring one or more extra hands in their operation; "That is to say, the mixer is usually mountedin'a given position and, from this point, the concrete mix is conveyed by wheelbarrows or the like to the point of ultimate use. The present invention contemplates a mixing device which reduces manual pp perations to a minimum and makes it possible for the driver of a tractor to initiate the mixing operation and subsequent delivery tojthe location of ultimate use wlhout leaving the tractor seat.

More specifically, the present invention can templates amiXing device which requires no di rect coupling with a prime mover, .such as an electric motor or internalcombustlonengine and,

Fig. 7 is an elevational view disclosing a mixing y ndcr'cr re pta le of m difi d form wh ch t thi d, it is proposed to so .mo'unta m x ng cylinder that in one position it" may be rolled along the surface of the ground in response to movement of the tractor, and-.elevated'irolh the ground to enable translation of the mixed ma terial to the place where it is to he, used. 7

"It is a further object of the present inyenticn to provide a mixing device/of the type referred to above which may be used in association with tractor attachments commonly k iownto those skilled in the art as tractor loader attachments. The invention proposes the use of a rotary mix-.1 ing receptacle or cylinder which may be supported at the free extremity of tractor loader frames.

The foregoing and other objects and advan-' tages will be more apparent from the following detailed description when considered in connection with the, accompanying drawings, wherein is quipped Witha singleicentral tread, as distinguished from the dfi llble'tread of the mixin reeptaclle hOWII 1 1 the pre edin figu es nd;

Big. 8 is a detailed perspective view of the lower portion of the mix ng ece acle of its ustrating the manner in which a peripheral portion of the tread maybe opened to permit discharge of concrete mix and the like from the receptacle. Referring now to the drawings more in detail wherein, like numerals have been employed to designate similar parts throughout the various figures, it" will be seenfrorn Fig. 1 that the in.- vention contemplates a. rotary mixing device, des gnated en al y y th um al l wh ch is capable of bein .rotatably supported at the free extremities of a pair of arms I2 and I4. These arms form a part .of a frame structure commonly known in the farm machine industry as tractordoader structures or frames. The ex.- tremities of the arms l,2 -I4, opposite from the extremities which support the mixing device [0, are pivotally mounted to the structure of a conventional tractor designated generally by the numeral [6. Detailed descriptions of the tractor, as well as the loader frame structure, are not believed to be necessary for clear comprehension of the present invention. It will suflice tostate vthat the loader frame structure includes, in addition to the aforesaid arms l2 and M, an

upright frame device l8 as well as tie bars or frame elements 20, which extend between the upper portions of the frame [8 and the forward extremities of the arms l2-I4. Tie bars or frames 22 extend rearwardly and downwardly between the upper part of the frame I8 and the frame or body portion of the tractor I6. Hydraulic actuator mechanisms 24 are employed to impart tilting movement to the aforesaid frame structure, including the arms l2--l4. It will thus be apparent that through the agency of the aforesaid frame structure and hydraulic actuators, the mixing device 10 may be'shifted between the solid line elevatedposition and the dotted line lowered position illustrated in Fig. 1. The mixing device l illustrated in Figs. 1-4, inclusive, consists of a receptacleproper 26 having fixed wall portions extending between wheels 28 and 30. Each wheel 28-40 is equipped with a suitable tread 323 i, respectively. The end wall 36 of the mixing receptacle 26 is carried by the when 28' and a similaroppositely disposed end wall 38 is carried by the Wheel 30. A suitable shaft 40 traverses the receptacle l0 and extends suiiiciently beyond each of the end walls 3638 .to provide a trunnion 'support within frame arms 42 and 44. These arms 42 and 44 are'pivotall supported at 46-48 at the free ends "of the frame arms l2-l4, respectively. The downward tilting. of the arms 4244 is limited'by the engagement of the inner extremities of said arms with a cross arm member 50, Fig. 4.

In order to condition the receptacle I0 for'receiving a'charge of ingredients to be mixed, it is only necessary to'impart rotation to the handle 52 which operates through a pinion 54 and large gear 56 carried by the end wall 36 until a door 53 is properly positioned for opening. This door 58 is secured in closed position by suitable manually operable latch mechanisms 60. When the door has been unlatched, it may be swung open, as shown in Fig. 2. With the open sideof the receptacle facing outwardly, a charge of mixing ingredients may be deposited within the recepta'cle. In this connection, attention is directed to a group of suitable mixing baffles 62 traversing the central portion of the receptacle and suitably secured, as by welding," to opposite walls of the receptacle, as well as to the shaft 40. Upon subsequent .rotation of the receptacle, these baffles function aggressively to bring about com.- plete mixing when the receptacle is rotated. Having charged the mixing receptacle the cover is again secured in latched position.

With the frame members l2 l4 in their lowered position, the mixing receptacle may now be rolled along the surface of the ground. Such movement is occasioned by driving the tractor ina given direction, either forwardly or reversely or both, and the time of such mixing .will, of course, depend upon the nature of the ingredients to be mixed. After this operation has been completed, the operator of the tractor occupying the tractor seat 64 causes the receptacle supporting frame to be elevated to. the position shown in Fig. l. The completelymixed ingredients may now be translated to the place of ultimate use. To facilitate direction of the mixed ingredients as they are poured from the receptacle Hi, use may be made of a chute device designated generally by the numeral 66, Figs. and This chute device 66 hasan upper portion 6d provided with a strip of angle iron 10, adapted to liegoyer and interlock with an upstanding lip portion" 12" of the receptacle lll,-Fig. 6. A chute 4 portion 14 diminishing in width towards its free extremity is pivoted at 16 to the portion 68. This arrangement enables the discharge end of the chute portion 14 to be swung through a substantial arc.

In Figs. '7 and 8, a slightly modified form of mixingreceptacle is shown, which receptacle is designated generally by the numeral a. The main difference between the receptacle la and the receptacle I0 is in its longitudinal cross sectional shape and the incorporation therein of a single central tread 18, as distinguished from the double tread arrangement 3234 of the device just described. This single tread 18 is in thenature of a wheelbarrow and is particularly adaptable forusein instances where the surface of the ground isuneven. The receptacle Illa is provided with a pivotal door section 58a which may be lowered to the position illustrated in Fig. 8 when it is desired to unload mixed ingredients from the receptacle. Except for the difierence in configuration, the receptacle [0a functions similarly to the receptacle Hlin its operativeassociation with the tiltable frame members |2I4.

From the foregoing, it will be apparent that the present invention contemplates a mixing device for constructional aggregates, such as cementitious materials and the like, of extremely simple, yet practical, construction. By use of this device, the necessity for employing expensive, complicated, self-contained mixing units is completely obviated. Any farmer owning a tractor can, with little added expense, equip the tractor with the mixing device formingthe subject matter of the present invention. In fact, if the tractor is equipped with conventional tractor loader frames, such. as the tiltable frame structure disclosed herein, it is only necessary to replace the loader structure at the free extremities of the loader arms with the mixing receptacle. This is accomplished by mounting the receptacle supporting shaft with the use of nuts or the like at the free extremities of the loader arms. In these days, when farm help is at such a premium, the present invention is of special practical signicance'in that it'enables structural work in the nature. of concrete pouring' and the like to be carried on" without employing additional labor. In fact; the farmer himself, with a minimum of effort, can mix cement without the necessity of incurring financial obligations incident to hiring labor and capital investments in the form of expensive machinery.

While, for the purpose of illustration, the invention has been described in connection with certain'structural details and des'igns,'it should be understood'that the invention is not limited to these structural details but is capable of other modifications and changes without departing from the spirit and scope of the appended claims.

The invention is hereby claimed as follows:
