RICHARD L. MILLER, OF ST. LOUIS, MISSOURI.
HAND CONCRETE-MIXER.
Application filed September 23, 1918.
To all whom 2'25 may concern:
Be it known that I, RICHARD L. MILLER, a citizen of the United States, and resident of St, Louis, Missouri, have invented certain new and useful Improvements in Hand ConcreteMixers, of which the following is a specification.
This invention relates to improvements in a hand concrete mixer, and has for its object a suitable frame in which is axially mounted a container in which the concrete is to be mixed, an agitator supported in the container and handles for placing the container in partial rotation.
The essential feature of my invention is to construct a mixer in which a certain quantity of concrete can be mixed, the same being operated by hand and to be constructed of such material as to make the same inexpensive and adaptable for use at any place or locality.
Figure 1, is a side elevation of my complete invention.
Fig. 2,-is a front view of the same.
Fig. 3, is a vertical central sectional view.
Fig. i, is a central cross sectional view.
Fig. 5, is a detail perspective view of a portion of the agitator together with the supporting block by which the agitator is supported in position.
Referring to the general construction of my invention 6 indicates a base frame consisting of two side timbers 7, base boards 8, a front cleat 9, and to the interior of the side timbers 7 are firmly bolted a pair of uprights 10. Against the edges of the uprights 10 are fastened a pair of cross members 11, which extend across the width of the frame 6 and assist in holding the uprights 10 in a rigid braced position.
Against the outer surface of both of the uprights 10 is attached a brace member 12, which rests upon the upper edge of the side timbers 7 and to the braces and against the side timbers 7 is firmly bolted a supporting member 13.
In each of the uprights 10 and brace members 12 is provided an aperture or bore 14: in which are inserted nipples 15, which act as journal bearings for the center supporting shaft 16, which shaft is held in position by means of the nuts 17.
Axially mounted on the shaft is a mixing compartment or receptacle 18, which consists of a pair of side walls 19, the edge being covered by a strip of sheet metal 20,
Specification of Letters Patent.
Patented Feb. 4:, 1919.
Serial No. 255,408.
7 the bottom of said receptacle being formed on the radius of a circle, while the upper open end 21 is approxin'iately rectangular in form.
011 each side of the receptacle is provided a handle 21 by which the mixing compartment is operated so as to swing the same backward and forward on the axle 16.
On each side 19 of the receptacle I place an additional supporting member 22 which is in the form of a strip running across the side and through this and the sides 19 is provided a bore 23 through which is inserted by a driving fit a pipe or tube 24, through which the shaft or axle 16 is passed and which also acts as a proper journal bearing for the movement of the mixing compartment.
On the inner sides of the walls 19 of the mixing compartment and in close proximity with the tube 24 are secured supporting blocks 25 which are provided with a rectangular recess 26, in which is inserted and supported a cross bar 27, to which is firmly attached a plurality of agitator arms 28.
It will be observed from the foregoing that the lower portion of the mixing compartment is formed on the arc of a true circle, which permits the material to shift and change position more readily and uniformly, and the machine to be operated more easily by hand. The tube 24 in addition 'to forming a bearing on which the mixing compartment oscillates on the shaft,
also protects said shaft from the accumu-.
lations of cement and mortar thereon. The supporting blocks 25 answer as an inexpensive and firm support for the ends of the member or timber 27, which carries the agitator arms.
The general agitator construction is such that the same can be readily and easily inserted in position or removed therefrom when necessity requires; and when placed in position, the same may be held by placing a screw through the walls 19 into the ends of the bar 27.
The general operation of my invention is as follows:
The required quantity of material to be mixed for forming a proper concrete mixture is inserted into the receptacle through the opening 21, then the required amount of water is added and then by partially rotating the receptacle by the manipulation of the handles 21, the receptacle is rocked backward andforward in arcanner as that shown by dotted lines in Fig. 3, and by the moving process the agitators will pass through the material intermingling the various ingredients and after the mixing process has been completed the mixture is then discharged from the container by lowering the same in a position as that shown by the dotted lines indicated by the numeral 29.
For a matter of cheapness the device is preferably constructed of wood thereby making the same of a nature which can be purchased and handled by a small contractor who is not financially able to purchase an expensive mixing machine.
By practice the device has been found to operate successfully and thoroughly mixing the ingredients as is required in concrete construction.
Having fully described my invention whct I cla m is A concrete mlxer comprising a support,
'astationary shaft secured at its ends on said support, a mixer receptacle having a curved bottom, a tube within said receptacle mounted on said'shaft, a cross-bar connected to said receptacle and agitator bars secured to said cross bar and extending to near said curved bottom; and means connected with said receptacle for oscillatin the same on said shaft, said tube being fixedly secured to the receptacle at its ends and forming a bearing for sa-idshaft.
In testimony whereof, I have signed my name to this specification, in presence of two subscribing witnesses.
