MIXING-MACHINE FOR CONCRETE OR THE LIKE.

SPECIFICATION forming part of Letters Patent No. 781,727, dated February 7, 1905.

Application filed March 16,1903. Serial No. 148,019.

To 11]] u'lmm/ it In/my (mu/carna- Beitknown that I, \VILLIA): J. JUDD, acitizen of the United States, residing at New York, in the county of New York and State of New York,have invented certain new and useful lmprovements in Mixing-Machines for Concrete orthe Like, of which the following a specitication.

Hy invention relates to machines for mixing concrete and the like in which the materials are introduced into a mixing-receptacle supported to revolve about a tilting axis, the mixing-receptacle thus charged with materials being revolved about said axis to effect the mixing and being tilted at a proper moment for the purpose of discharging the mixed-up batch.

Objects of my invention are to rapidly and effectively mix the materials introduced within the mixing-receptacle; to secure a quick and clean discharge from the mixing-receptacle; ti) cause the mixed-up batch to be automatically discharged by the rotary action of the mixing-receptacle; to avoid all necessity for providing the rotary mixing-receptacle with mixing-blades or the like, thereby dispensing with objectionable internal projections to which concrete and the like is apt to adhere to an extent to preclude a clean and complete discharge; to reduce the time consumed in the operation of charging, mixing, and discharging; to charge the mixing-receptacle without causing the materials to clog the passage provided for their introduction; to provide an improved chute or hopper device adapted for directing materials into a rotary tilting mixing-receptacle during the rotation of the latter and operated to automatically swing away from a charging position when such receptacle is tilted to discharge the mixedup batch; to insure certainty of action and proper relative positions on the part of the automatic chute or hopper; to provide a compact, convenient, and etlieient portable mixer which can be readily drawn from place to place along roads or streets and positioned for mixing up concrete for sidewalks and the like; to readily and conveniently supply the mixer with Water in suitable quantity during operation; to effect the discharge of a mixed-up batch at a convenient point; to provide a simple and etlicient construction and organization of po\ver-transmitting mechanism ar ranged between an engine or motor and the rotary mixing-receptacle and adapted to continuously revolve the mixingreceptacle, whereby the latter can be tilted withoutarresting its rotative action; to provide a construction and arrangement whereby the rotary tilting mixing-receptacle, the engine or motor,and the intervening powcr-transmitting mechanism are compactly and conveniently mounted upon a comparatively light wheeled carriage, and to provide certain novel and improved details ofconstruction and arrangement in mixing-machines for concrete and the like.

In the accompanying drawings, Figure I is a side elevation of a 111ixing-n1achine en1body ing my improvements. Fig. 2 is a top plan view of the same. Fig. 3 shows the machine in end elevation. Fig. 1 is a longitudinal vertical section on line .r :1 in Fig. 2, the mixingreeeptacle being shown in position for receiving and mixing. Fig. 5 is a like section with the mixingreceptacle in position f rdischarging its contents, the engine being omitted.

A indicates a carriage having front and rear wheels B and C and havingits body-frame 1 supported upon and above the front and rear axles for such wheels, so as to suitably elevate the rotary mixing-receptacle l), whichis in turn supported to tilt upon the body-frame. 'Ihe carriage thus constructed an be drawn along a road or street by one or more horses, and to such end it is desirably provided with a suitable tongue where two horses are employed or with shafts 2 when one horse is deemed sufficient. The rotary mixing-receptacle is arranged to discharge at the rear end of the carriage and is arranged back of an engine or motor F, which is mounted upon the body-frame of the carriage and employed for rotating the mixirig-receptacle, the driving connection between the motor or engine and the mixing-receptacle being preferably arranged to permit the continuous rotation of the mixing-receptacle during the successive operations of charging, mixing, and discharging. The motor or engine may be of any approved type or construction, the motor represented being an ordinary gasolene-engine. The mixing-receptacle is indirectly supported upon the body-frame of the carriage by means of a tilting frame F, which is pivoted between its ends upon the bod y-frame by means of suitable trunnions or side journals. In the construction illustrated the longitudinal side bars 3 of the tilting frame are arranged opposite the outer sides of the longitudinal side bars 4, Fig. 2, of the body-frame and are rigidly connected together at points in rear of the mixing-receptacle by cross-bars 5 and 6, which serve to support a portion ofthe driving mechanism, the cross-bar 5 also affording a support for the rear journal 7, Fig. 4, of the mixingreceptacle. Vith this arrangement the crossbars 5 and 6 extend over the side bars of the bod y-frame and rest thereon when the mixing receptacle is in mixing position, as in Fig. 4, whereby the mixing position of such receptacle'is readily determined. The portion of the mixing-receptacle at which the discharge takes place is indirectly supported upon a cross-bar 8, Fig. 3, at therear end of the tilting frame. When the axis about which the mixing-receptacle is horizontal, as in Fig. 4, the rear crossbar of the tilting frame will lie in a horizontal plane parallel with but below the plane of the rear cross-bars 5 and 6, this relative drop on the part of the rear cross-bar being, for example, attained by mounting the end portions of the rear cross-bars 5 and 6 upon the side bars 3 of the tilting frame and securing the front cross-bar 8 to the under sides of the said side bars 3, and in this way when the mixing-receptacle is in mixing position the rear cross-bar 8 of the tilting frame will bear against the under sides of theside bars 4 of the carriage frame or body.

The mixing-receptacle illustrated is a cubiform box supported to revolve about a tilt- .ing axis passing through diagonally opposite corners and having one of such vertices or corners cut away to provide an opening through which the material is ejected when such axis is properly inclined. In order to form this corner portion of the box or receptacle with a suitable opening, it is desirably constructed with a plate 9, Fig. 5, having a circular opening and an annular flange about such opening and forming a short neck 10, through which the mixed-up batch passes when the box is in position for discharge, as in Fig. 5. The plate 9 is also provided with an outer annular flange 11, concentric with the flange 10, Fig. 3, and forming a journal which bears upon antifriction-rolls 12 on the rear cross-bar 8 of the tilting frame. The discharge opening or passage 13 is coincident with the tilting axis about which the mixing box or receptacle revolves and is arranged for discharging a mixed-up batch at the rear end of the carriage, which has a greater spread to its rear wheels than to its front wheels, so that when the mixing-receptacle is in position for discharge, as in Fig. 5, an ordinary wheelbarrow can be placed under the dischargeopening to catch the batch discharged.

While the mixing-receptacle can be provided with a side door which can be opened for the purpose of chargingthe mixing-receptacle when the rotation of the latter is arrested, I prefer to employ the opening 13 for both charging and discharging, it being observed that said opening is coincident with the tilting axis about which the mixing-receptacle revolves. The mixing receptacle (shown in the form of a cube box) has the opening 13 at one corner portion and is provided at its diagonally opposite corner portion with a hollow journal 7, coincident with the axis of rotation and supported by a hearing 14, which is arranged upon cross-bar 5 of the tilting frame and provided with suitable means for oiling. such as an oil-cup 15. The hollow journal 7 permits the introduction of water into the mixing-receptacle, and to such end a pipe G. is extended through the hollow journal 7 and at its outer end connected with a flexible hose-pipe 16. which can be extended to and connected with any suitable source of supplysuch, for example, as an ordinary street connection for such hose-pipe. The pipe G is secured to the tilting frame F as, for example, to the rear cross-bar 6 of said frame it being seen that when the tilting frame which thus carries the pipe G is tilted the flexible -hose will permit such movement on the part of the tilting frame. Upon the outer end portion of the journal 7 is secured a bevel-gear H. This bevel-gear H is engaged by a pinion 17, Fig. 2, which is fixed upon a short transversely-arranged counter-shaft 18. This counter-shaft 18 is supported by bearings 19 and 20 on the tilting frame and has at one end a belt or sprocket wheel 20, Fig. 1, which said sprocket-wheel is connected by an endless link belt 21 with a smaller sprocket 22, arranged to revolve about an axis transverse to the axis of rotation of the mixing-receptacle and constituting the horizontal axis about which the mixing-receptacle tilts. The sprocket 22 is therefore arranged to revolve about one of the journals or trunnions 23 for the tilting frame, and in order to gear-connect it with the rotary engine-shaft 24 it is formed upon or secured to a belt-wheel 25, which is in turn connected with a belt-wheel 26 on the engineshaft by means of an endless belt 27. With this arrangement the belt 27 is parallel with and arranged alongside of one of the side bars 3 of the tilting frame and the link belt 21 is arranged between and parallel with one of said side bars 3 of the tilting frame and the power-transmitting belt 27, thereby providing a simple and compact driving arrangement and also permitting the frame F, which carries the counter-shaft 18, to readily tilt.

ln order to readily charge the mixing-receptacle, a swinging chute or hopper l is supported upon the tilting frame and arranged to automatically swing into position for directing materials into the mixing-receptacle when the latter is in mixing position, as in Figs. 1 and l, and to automatically swing away from the discharge-opening when the mixing-receptacle is in position for discharge, as in Fig. As a means for thus automatically actuating the hopper I it is pivotally supported upon the tiltingframe and connect ed with the body-frame of the carriage by an operating device which causes the hopper to swing as the result of relative movement between the tilting frame and the body-frame of the carriage. best shownin Fig. 3, the hopper is secured to and suspended from a roclc shaft 28, which is in turn supported by an upright frame 29 on the rear cross-bar 8 of the tilting frame. This rock-shaft 28 is provided at one end with a crank-arm 30, which has a pivotal connection with a fixture, such as a bar 31, secured upon the body frame of the carriage. hen therefore the mixing-receptacle is tilted from the position shown in Fig. i to the position shownin Fig.

5, the relative movement between the tilting l support and the body-frame of the carriage will cause the hopper to swing away from the discharge-opening, as in Fig. 5, and when the tilting frame is swung back into the position shown in Fig. 4: the hopper will be brought into position to discharge the materials well into the opening 13 of the mixing-receptacle. The tilting frame is also provided with a short trough or deflector K, which is secured upon the rear end of the tiltingframe and arranged to properly direct the discharged batch when the mixing-receptacle is in position for discharge, as in Fig. 5, it being observed that this short trough K is shown concave in crosssection and has its inner end adapted to the external contour of flange 10 on plate 9 of the mixing-rece fitacle.

In the construction of mixing machine shown the polyhed ric or cubiform mixing box or receptacle is both charged and discharged through an opening at one of its corner portions, and it can be thus charged and discharged while revolving about an axis extending through the single opening thus provided. "hen the axis of rotation of such box is horizontal, or substantially so, the chute or hopper will be in position to project into the opening 13, and thereby direct the materials into the box, and by this arrangement the passage formed by such openingl3 may be of sufiicicnt length to also adapt it for a discharge-passage, while by thus projecting the lower end of the hopper within such passage the materials will be directed into the box to an extent to prevent accumulation of materials in the passage referred to. When the box is revolved in mixing position, the materials will be rapidly and effectively mixed without the use of blades or stirrers, and when the box is tilted into position for dumping the mixed-up batch the latter will be ejected by the rotary action of the box, which in thus revolving constantly changes the angles of its inner sides relatively to a horizontal line and causes all of the corners of the box excepting the two diagonally opposite corners, through which the axis of rotation passes, to swing round in planes which incline upwardly and forwardly, thereby carrying the material toward the discharge side of the machine. The corner portion of the box which isdiagonally opposite the corner portion through which the inlet and outlet opening is formed is practically a closed corner through which a small pipe may beinserted by way ofanaxial perforation made for such purpose, and when desired the water-supply pipe can be omitted and the journal 7 can be made solid. By thus practically closing the box at the front and charging and discharging at the rear portion thereof the motor or engine can be set comparatively close to the box and the journal 7 can be mounted direct in bearing H and be extended beyond the same, so as to carry the gear H, thereby 9 dispensing with supporting-rolls and providing a simple and mechanically-desirable support at this point, it being observed that in the machineillustrated it would be both inconvenient and undesirable to attempt to so open the practically closed corner referred to as to permit the box to be charged at this point. By charging and discharging at the rear corner room is afforded for the deflector K, which prevents material from sitting onto the rolls 12 and getting in between the journals ot'such rollsand their bearings, and the driving mechanism 'can be placed whereby it will be out of the way of materials delivered to the box.
