Abstract
Abstract This mixer is for a manullay mixing mortar, concrete or the like in relatively small batches. A rotatable mixer barrel is supported on a wheeled frame by a bearing at its closed end and a circular guide wheel engaging grooved support wheels at its open end. The mixer barrel is rotated by means of the guide wheel. It can be dumped by manually tilting the frame.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
249 words
A mixer comprising: frame means having first and second ends and a longitudinal frame axis, a pair of frame wheels for transporting the mixer mounted at said first end of said frame means parallel to said frame axis, handle means mounted on said second end of said frame means, a pair of mixing barrel support wheels rotatably mounted on said frame means at said first end thereof, said pair of support wheels being spaced from one another laterally flanking said frame axis and being generally vertically oriented, said mixing barrel support wheels having annular grooves extending around the entire periphery thereof, bearing means mounted on said frame means along said frame axis spaced from said first end, said bearing means having a bearing opening for receiving a mixing barrel shaft, a mixing barrel of generally frustoconical shape having side walls, a base, and an opening opposite said base, a mixing barrel shaft attached to said base along a mixing barrel axis and engageable with said bearing means, a circular handle ring mounted on said mixing barrel surrounding said mixer opening, said handle ring being mounted on arm means attached to said mixing barrel and spacing said handle ring radially from said mixing barrel, the axis of said ring being coincident with the axis of said mixing barrel, said ring being engageable with said grooves in said mixing barrel support wheels and functioning to support said mixing barrel and to be grasped by the operator to rotate said mixing barrel.
Claim 2
Dependent Claim
249 words
A mixer comprising: frame means having first and second ends and a longitudinal frame axis, a pair of frame wheels for transporting the mixer mounted at said first end of said frame means parallel to said frame axis, handle means mounted on said second end of said frame means, a pair of mixing barrel support wheels rotatably mounted on said frame means at said first end thereof, said pair of support wheels being spaced from one another laterally flanking said frame axis and being generally vertically oriented, said mixing barrel support wheels having annular grooves extending around the entire periphery thereof, bearing means mounted on said frame means along said frame axis spaced from said first end, said bearing means having a bearing opening for receiving a mixing barrel shaft, a mixing barrel of generally frustoconical shape having side walls, a base, and an opening opposite said base, a mixing barrel shaft attached to said base along a mixing barrel axis and engageable with said bearing means, a circular handle ring mounted on said mixing barrel surrounding said mixer opening, said handle ring being mounted on arm means attached to said mixing barrel and spacing said handle ring radially from said mixing barrel, the axis of said ring being coincident with the axis of said mixing barrel, said ring being engageable with said grooves in said mixing barrel support wheels and functioning to support said mixing barrel and to be grasped by the operator to rotate said mixing barrel.
Claim 3
Dependent Claim
59 words
The mixer of claim 1 wherein said mixer is pivotable by means of said handle about the axis of said frame wheels between an operating position wherein said mixing barrel axis is inclined downwardly to the horizontal from said mouth and a dump position wherein said mixing barrel axis is substantially vertically oriented and said mouth is downwardly oriented.
Claim 4
Dependent Claim
23 words
The mixer of claim 2 wherein the axes of rotation of said mixing barrel support wheels are parallel to said mixing barrel axis.
Claim 5
Dependent Claim
64 words
The mixer of claim 2 wherein said handle means is of generally U-shaped configuration and oriented generally perpendicular to said mixing barrel axis, and said frame means comprises a pair of base members attached to said handle means generally perpendicularly thereto, whereby said mixer can be tilted to a load position resting upon said handle means with said mixing barrel axis generally vertically oriented.
Claim 6
Dependent Claim
15 words
The mixer of claim 4 wherein said bearing means is attached to said handle means.
Claim 7
Dependent Claim
30 words
The mixer of claim 4 wherein said U-shaped handle means is joined to said base members by a curved portion to facilitate tilting of said mixer to a load position.
Claim 8
Dependent Claim
22 words
The mixer of claim 4 wherein the peripheries of said frame wheels are substantially in alignment with a plane across said mouth.
Claim 9
Dependent Claim
22 words
The mixer of claim 4 wherein the peripheries of said mixing barrel support wheels are at least partially shielded by shield means.
Claim 10
Dependent Claim

The mixer of claim 8 wherein each of said mixing barrel support wheels is mounted on a support plate attached to the end of one of said base members, and wherein said shield means comprises a flange attached to said plate and extending above said mixing barrel support wheel.
Claim 11
Dependent Claim
31 words
The mixer of claim 1 wherein said bearing means is pivotally mounted upon said frame, the pivot axis of said bearing means being perpendicular to the axis of said mixing barrel.
Claim 12
Dependent Claim
21 words
The mixer of claim 1 wherein said bearing means comprises a bearing sleeve and said shaft closely fits within said sleeve.
Claim 13
Dependent Claim
24 words
The mixer of claim 1 wherein the diameter of said circular ring is substantially the same as the major diameter of said mixing barrel.

The mixer of claim 1 further comprising at least one support foot extending downwardly from said frame means intermediate said first and second ends.
Claim 15
Dependent Claim
20 words
The mixer of claim 1 further comprising a plurality of mixing blades attached to the inside of said mixing barrel.
Claim 16
Dependent Claim
32 words
The mixer of claim 1 wherein said annular grooves of said mixing barrel support wheels are of such depth as to prevent appreciable lateral movement of said circular ring with respect thereto.
Claim 17
