Application filed November ai, 1921. Serial No. 516,577. I
To. all 4.0 ham it may concern Be it known that I, BERT G. CARnY, a citizen of the United States, and resident of "Sioux City, in the county of W'oodbury and State of Iowa, have invented certain new and useful Improvements ers, of which the following-1s a specifica tion.
device. 7
Another object of the invention is the pro duction of a concrete-mixing devioe'embodying" a rocking mixing-container and im proved means for preventing the entrance thereinto of large rock. Furthermore, the
'invention contemplates a concrete mixer embodying a rocking material container and means for preventing theentrance thereinto of large rock, and which means-retains the rock and is so constructed that when the container is rocked to eject its contents into the large rock are dumped into the receptacle prior to the ejection of the fmixed material.
These and other objects and advantages are successfully obtained in the embodiment hereinafter described, defined in the appended claims and illustrated. in the accoupanying drawing, which forms a part of this application and in which like characters of reference indicate corresponding parts in both views, of which: I I
Fig. 1 is a' plan of a device constructed in accordance withthe invention, parts being cut away, and 1 Fig. 2 is a fragmentary side elevation thereof.
While I have illustrated and hereinafter described the preferred embodiment of the invention, I would not be understood as being limited to such specific construction, for
various alternations and modifications may members, 1, and supported by suitable legs,
5. at the corners.v The frame supports a material-mixing receptacle, preferably comwith heads, or end' walls, icoaxially through the receptacle is a shaft, 7 in suitable bearings, 9, on the in Concrete Mixshaft, 15,
prising'a sheet metal cylinder,
horizontally within the frame and provided 8, journaled frame-members, a. 1 Within the receptacle disposed I Extending the shaft carries radial arms,.10, disposed Y Jin different radial planes and adaptectto My inventionhas for its object the pro duction of an improved concrete-mixing agitate the material within, the receptacle by rotation of the shaft, which may be {LC/U111 ated by a crank, 11, on the shaft, 8, or otherwise. The upper 'side of the receptacle is open, as at 12, and at the sides joffthe said opening, 12, the receptacle is-form'ed-with flanges, 13. To one end of the receptacle j the receptacle todump the material there from, as will presently be made morezcleari I provide above the opening, 12, a swinging grate which serves to prevent entrance of large rock intothe receptacle and retains them until-the receptacle is dumped. The said grate comprises, m antime suitable V 1 extending 'longitudinallyof -.and adjacent the rear of the 'opening.: ,12, and journaled' in suitable bearings, 16, carried by the receptacle; The shaft, 15,is,provided with a series of spaced gate-bars, 17, which j are curved downwardly, as at 18, topretain rock which arev too largejto pass between the bars and are retained. thereby.
At one endof the'serie's o fvgrate bars is a straight-"bar, 19, which normally rests'upon the adjacent flange, 13, to support the grate in its normal position. At the opposite end ofthe series the shaft, 15, carries an arm, 20,- spaced above the bars, '17 and 19, and having a curved end, 21. ()bviously, the concrete materials are introduced in to the receptaclethrough the opening, 12, and as the previously stated, any large rock which might damage the agitating-means within the receptacle are re rained by the grate. The material is then mixed through rotation of the shaft-,8, and
then dumped from the receptacle by upward movement of the lever-arm, 1 1. The
initial rotary movement of the 1 ."eceptaclev intll act of dumping brings the grate to an inclined position, as indicated in dotted lines at 22, to permit the large rock to drop from the grate, in which position the curved end of the arm, 20, rests upon the front frame member, 3. Then, upon further rotary movement of the receptacle the said arm, 20, slides upon the frame-member, 3, and coacts with the shaft, 15, to lift the grate from the opening, 1:2, permitting the unobstructed dumping of the material from the receptacle and onto the rock previously dumped from the grate. Thus, it will be seen, large rock are retained by the grate, during the mixing process, and the mixture is then dumped directly on the rock. Ex: tendingacross the rear periphery of the .receptacle is an angle-iron, 23, the end portions of which project over the supporting frame, the said angle-iron serving to stiffen the receptacle, and its projecting ends serve as stops which engage the frame memhers, 4, to limit the forward rocking move ment of the receptacle. Obviously, the receptacle and its grate are restored to their normal positions by rocking the receptacle rearwardly through the medium of the lever-arm, 14.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is:
1. A concrete mixer embodying a mixing receptacle having an upper opening and mounted to rock between normal and dumping positions, a guard grate normally extending across said opening and hinged to the receptacle to swing from the opening, and an element fixed, with respect to the receptacle, to be positively engaged by the grate when the receptacle is swung to dumping position, to swing the grate from the opening.
2. In a concrete mixer a suitable support, amixing receptacle having an upper opening and mounted on the support to rock between normal and dumping positions, a guard-grate normally extending across said opening and hinged to swing from the opening, and means governed by movement of the receptacle to its dumping position and coacting with the'supp'ort to swing the guard-grate from the opening.
3. A concrete mixer embodying a mixing receptacle having an upper opening and mounted to rock between normal and dumping positions, a guard-grate normally extending across said opening and including a rock-shaft positioned adjacent one side of the opening, and a series of spaced bars carried by the shaft and normally extended across the opening, and an element fixed with respect to the receptacle to be positively engaged by the grate when the receptacle is swung to dumping position, to swing the grate from the opening.
4;. In a concrete mixer a suitable support, a mixing receptacle having an upper 0pening and mounted on the support to rock between normal and dumping positions, a guard-grate normally extending across said openingand including a rock shaft positioned adjacent one side of the opening, and aseries of spaced bars carried by the shaft and normally extended across said opening, and means governed by movement of the receptacle to its dumping position and coacting with the support to swing the guardgrate from the opening.
5. In a concrete mixer a suitable support, a mixing receptacle having an upper opening and mounted on the support to rock between normal and dumping positions, a guard-grate normally extending across said opening and including a rock shaft posi tioned adjacent one side of the opening, and a series of spaced bars carried by the shaft and normally extended across said opening, and an arm on the rock-shaft engageable with the support when the receptacle is moved to its dumping position, to turn the rock-shaft and thereby move the said bars from the opening.
In testimony whereof, I have hereunto set my hand this 5th day of May, 1921.
BERT C. CAREY.
