FREDERICK T. ARNOLD, OF FORT ROBINSON, NEBRASKA.

MIXING-MACHINE.

Specification of Letters Patent.

Patented Aug. 9, 1910.

Application filed October 28, 1909. Serial No. 525,081.

To all whom it may concern:

Be it known that I, FREDERICK T. :ARNOLD, a citizen of the United States, residing at Fort Robinson, in the county of Dawes and State of Nebraska, have invented certain new and useful Improvements in Mixing- Machines; and I do hereby declare the following to be a full, clear, and'exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to new and useful improvements in mixing machines and more particularly to that class adapted to be used for mixing plastic materials, such as con crete, mortar, plaster, etc., for all classes of construction and my object is to provide means for gearing the receptacle to one of its supporting wheels whereby when the wheel is rotated, the receptacle will-be likewise rotated and a further object is to provide suitable means for operating the gearing mechanism, whereby the receptacle will be attached to or disconnectedfrom the wheel.

Other objects and advantages will be hereinafter referred to and more particularly pointed out in the claims.

In the accompanying drawings forming part of this application, Figure 1 is a front elevation of the mixing device complete. Fig. 2 is a vertical central sectional view therethrough. Fig. 3 is an end elevation of the device. Fig. 4 is a similar view of the .op-

posite end of the device. Fig. 5 is a detail plan view of the mechanism employed for securing the closure in its closed position. Fig. 6 is a detail sectional View thereof, and, Fig. 7 is a detail sectional view through the hinged end of the closure.

Referring to the drawings in which similar numerals designate corresponding parts throughout the several views, 1 indicates the receptacle or body which is in form a modified regular octahedron in general outline substantially as shown on drawing and through the center of the body is disposed an axle 2, said axle being of sufficient length to roject beyond the walls of the body.

Sue Wall of the receptacle through which the axle extends, is provided with a flanged collar 3, which forms a bearing for that end of the axle, while the opposite end of the axle extends through the hub 4 of a bevel gear 5, said gear being attached to the outer face of the end wallof the body by means of rivets or the like 6 and the flanged collar 3 is likewise attached to its respective end of the body by means of rivets 7 and in order to securely brace the end wall through which the collar 3 extends, a spider 8 is introduced overthe bearing portion of the collar 3 and securely attached to the outer face of the end wall.

The receptacle 1 is securely held in position on the axle and prevented from moving longitudinally thereon by providing a circumferential grooove 9 in that portion of the axle 2 extending through the collar 3 and into said groove is introduced the end of a pin 10 carried by the collar 3, this construction permitting the receptacle to rotate independently of the axle, but holding the same against longitudinal movement thereon.

The ends of the axle 2 have mounted thereon supporting wheels 11 and 12, the wheel 12 being retained in position on the axle by providing a washer 13 which is introduced over the end of the axle and bears ag a inst the outer end of the hub of said wheel 12, a pin 14 being extended through the axle to retain the washer in position, while the inner end of the hub is engaged by a collar 15, which collar is fixed in any suitable manner-to the axle. The wheel 11 is caused to rotate with the axle 2 by providing a. key 16, said key entering a. seat. 17 in the axle and having a projetcion 18 thereon, which enters a seat 19 in the hub of the wheel 11, whereby when said wheel is rotated, the axle will likewise be rotated.

The key 16 is of considerable length and hasattached to its inner end a bevel gear 20, which is adapted to be moved into engagement and mesh with the gear 5, whereby the receptacle 1 will be rotated and as the key 16 is slidably mounted in the seat 17, said gear 20 may be moved into or out of engagementwith the gear 5 thereby. The outerend of the key 16 is provided with an upwardly extending tongue 21, which enters a spiral channel 22 on the interior of a. cam 23, saidcam. hax'ing a bore 24. extending inwardly from one end thereof, into which the end of the axle 2 is extended and said cam is rotatably mounted upon the end of the axle and held in position thereon by means of a screw 25, which screw extends through the closed end of the cam and enters the end of the axle and in view of the spiral trend of the channel 22, it will be readily seen that when the cam is rotated on the end of the axle, said key will be moved inwardly oroutwardly, thereby engaging or disengaging the bevel gears and it'will likewise be seen that by placing the cam adjacent the outer end of the hub of the wheel 11,. said cam will serve to prevent the wheel from leaving the axle. In order to readily operate the cam t rotate the same on the axle and move the gear 20 into engagement with the gear 5, a lever 26 is attached to the outer face of the cam 23, so that by grasping the lever and swinging the same in the arc of a eucle, the cam will be likewise rotated, the lever and cam being held in a fixed position when desired by providing 'alatch 27, the lower end of which-engages either one of a series of notches 28 in the periphery of the hub of the wheel 11, the latch 27 being operated through the medium of a spring pressed lever 29 adjacent the upper end of I the lever. 26.

the shaft 2, said collars being positioned between the wheels and the ends" of the receptacle 1 and to these collars are attached a frame or handle 31, whereby the vehicle or mixer may be propelled, but instead of using the frame, a pair of shafts (not shown) may be substituted therefor and the vehicle propelled by horsepower.

Attached to the end of the receptacle and extending over the gears 5 and'20- is a two-part shield 32, which is adapted to prevent foreignparticles from coming in direct contact with the gears and in order to further protect the bearing-parts of the device, each of the collars 30 is provided with a band 33, which extends a distance beyond each end of the collar and prevents the gravel, etc., from entering between the ends of the collar and parts adjacent thereto, the bands being fixed to the collar inany suitable manner.

The meeting edges of the several walls of the receptacle 1 are secured together and rendered water tight by lacing'over said meeting ed es suitable angle irons 34, which are secure in position over the edges by means of rivets 35 or otherwise, and in order 'to gain access to the interior of the receptacle, one of said walls is left free to form a door 36, one edge of which is at tached to the receptacle by means of hinges 37, while the remaining ed es are secured in position by means of suita le locks which comprise latches 38, which'are pivotally secured'around the edges of the door section 36, said latches having handles 39 thereon, whereby the latches may be readily. swung on their pivot bolts 40.

The free end of the latch 38 when swung into locked position extends over the edge ceptacle will be securely clamped together when the latchis introduced to itsfull extent into the notch.

To form a water tight seal between the edges of the door and the walls of the receptacle, strips of rubber or the like 44 and 45 are secured, respectively, to the edges of the receptacle 1 and door 36, the rubber 44 extending slightly beyond the edges of the walls of the receptacle 1 and contact with the rubber 45, around the edges of the door 36, so that when the latch is operated to lock the door in its closed position, the rubbers will be securely clamped together.

As before stated, this device is normally operated by pushing the entire device forwardly or rearwardly to thoroughly mix the contents of the receptacle, but if preferred, the gear 20 may be disengaged with the gear 5 aITdthe receptacle 1 rotated around the axle manually through the medium of handholds 46 which are placed at suitable intervals on the faces of the receptacle and these hand-holds may be also employed for turning the receptacle to such position as to discharge the contents thereof when the door 36 is opened and when the gear 30 is in mesh wlth thegear 5, the receptacle 1 may be rotated by turning the device in a circle, employing the wheel 12 as a pivot, the travel of the wheel 11 causing the receptacle 1 to rotate.

In operation, the lime, cement, sand and other products employed in formin the concrete or other plastic material are p aced at some distance from the construction for which the concrete is used and after a pro er quantity of the various ingredients, toget er with the proper amount of water are placed in the receptacle, the door is securely fas-' tened; The lever 26 is then rotated to move the-key 16 lengthwise and force the ear 20 tion and the same operation again performed. 7

By providing a device of this class, it will be readily seen that the arduous labor of mixing the ingredients with shovels, hoes or the like and requiring a number of men to perform the operation, will be entirely dispensed with and further in view of the small cost of the mixer, the same may be ably used on small jobs. It will further be seen that inview of the shape of the receptacle and the manner of mounting the same on the axle, the contents thereof will be thoroughly mixed when the receptacle is rotated as described and in'view of the lightness of the mixer,-it can be readily operated 'by one or two men and it will further be seen that as substantially all the parts of the device are constructed of metal, it will be practically indestructible from use.

What I claim is:

1. A mixing device, comprising the combination with a receptacle, of an axle extending through receptacle, supporting wheels for said axle, a key adapted to one of said wheels with the axle, a gear fixed to said receptacle, a similar gear fixed to one end of said key and means to move said key longitudinally, whereby .the gear on the key will be moved into or out of mesh with the'gear on the receptacle.

2. In a mixing device, the combination with a receptacle, an axle upon which said receptacle is rotatably mounted and wheels upon the ends of said axle; of a key adapted to fix one of the wheels-to the axle, a gear v for said axle, a key carried fixed to said receptacle, a similar gear fixed to said key, a cam rotatably mounted on one end of the axle and having a spiral channel therein, a tongue carried by the key adapted to enter said channel, a lever by means of which said cam may be rotated to move the gear on the key into or out of engagement with the gear on the receptacle and means to hold said cam in a fixed position. 3. A mixer of the class described comprising a receptacle, in form a modified regular octahedron, an axle extending through the opposite parallel triangular faces of said receptacle, supporting wheels y the axle and having a projection thereon adapted to engage one of said wheels and cause said wheel to rotate with the axle, a gear fixed to said receptacle, a similar gear carried by said key and adapted to be moved into engagement with the gear on the receptacle, a cam rotatably mounted on one end of the axle and having an interiorly disposed spiral channel, a tongue on said key adapted to enter said fix channel, whereby when the cam is rotated,

the key will be moved inwardly or outwardly, an operating lever for said cam and means to hold the cam against casual rotation. In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
