Abstract
Abstract A wheel press for removing extremely large tyres from their support rims, such as the tyres fitted to large Euclid type trucks having a load carrying capacity of about one hundred tons and upwards, and comprising a main support frame which supports in operative manner a pair of opposed platen assemblies, there being provided actuating means which co-operates with the platen assemblies to urge them towards or away from one another. The platen assemblies are provided with wheel engaging members which may be adjusted, to suit different sized wheels, to engage the parts of the wheel to be pressed, and said platen assemblies may be selectively arranged in an inoperative disposition, wherein a wheel can be easily loaded onto the wheel press.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
166 words
A wheel press for separating tires from wheel rims comprising a main support frame having mounted thereon in operative manner a pair of opposed platen assemblies, actuating means cooperating with said platen assemblies and operable for selective approach and retraction motion relative to said platen assemblies, wheel engaging means on said platen assemblies for engagement with the parts of the wheel to be pressed, said platen assemblies being in overlying alignment for pressing operations and capable of sufficient separation within said main frame for the insertion of said wheel between said platen assemblies, and guide means connected between said main frame and one said platen assembly for guiding said connected platen assembly from pressing alignment to a loading position outside of said main frame to enable a wheel to be loaded onto said connected platen assembly for subsequent movement of said connected platen assembly guided by said guide means from said loading position to said pressing alignment to enable the wheel loaded thereon to be pressed.
Claim 2
Dependent Claim
166 words
A wheel press for separating tires from wheel rims comprising a main support frame having mounted thereon in operative manner a pair of opposed platen assemblies, actuating means cooperating with said platen assemblies and operable for selective approach and retraction motion relative to said platen assemblies, wheel engaging means on said platen assemblies for engagement with the parts of the wheel to be pressed, said platen assemblies being in overlying alignment for pressing operations and capable of sufficient separation within said main frame for the insertion of said wheel between said platen assemblies, and guide means connected between said main frame and one said platen assembly for guiding said connected platen assembly from pressing alignment to a loading position outside of said main frame to enable a wheel to be loaded onto said connected platen assembly for subsequent movement of said connected platen assembly guided by said guide means from said loading position to said pressing alignment to enable the wheel loaded thereon to be pressed.
Claim 3
Dependent Claim
68 words
A wheel press according to claim 1 wherein said wheel engaging means comprise a plurality of spaced wheel engaging membErs on each platen assembly for supporting the wheel therebetween, each wheel engaging member being selectively movable in a radial direction with respect to a central point on each respective platen assembly and said point coincides substantially with the axis of a wheel operatively mounted on the wheel press.
Claim 4
Dependent Claim
26 words
A wheel press according to claim 2 and wherein each wheel engaging member is selectively movable along a track assembly fixed to the respective platen assemblies.
Claim 5
Dependent Claim
55 words
A wheel press according to claim 2 wherein each engaging member has two operable press surfaces, a first press surface which extends tangentially to the wheel rim of a wheel located operatively on the wheel press and a second press surface which extends radially of the said wheel axis for engagement with the wheel rim.
Claim 6
Dependent Claim
34 words
A wheel press according to claim 4 wherein the distance between each said first press surface and a track assembly for said wheel engaging members is greater than the width of said wheel rim.
Claim 7
Dependent Claim
36 words
A wheel press according to claim 1 wherein said guide means guides said connected platen assembly for movement in a plane substantially perpendicular to the direction of relative movement of the platen assemblies during pressing operations.
Claim 8
Dependent Claim
112 words
A wheel press according to claim 6 wherein each platen assembly is provided with substantially horizontal press surfaces, the upper platen assembly is selectively movable by said actuating means in a vertical direction towards and away from the bottom platen assembly which is restrained against movement in a vertical direction by said main frame, said guide means comprising a substantially vertical pivot means for connecting said bottom platen assembly to said main frame for guided pivotal movement of said bottom platen assembly in a substantially horizontal plane, and means operable to selectively pivot said bottom platen assembly about said vertical pivot axis to and from said pressing alignment and said loading position.
Claim 9
Dependent Claim
39 words
A wheel press according to claim 7, wherein the means to selectively pivot the bottom platen assembly about its said vertical axis comprises a manually controlled extensible hydraulic ram connected between the bottom platen assembly and the main frame.
Claim 10
Dependent Claim
73 words
A wheel press according to claim 1, and wherein said actuating means comprises a plurality of extensible hydraulic rams connected between the main frame and one of said platen assemblies which is movable towards the other platen assembly which is restrained against movement during pressing operations, and wherein displacement equalizing means co-operate with the movable platen assembly to prevent mis-alignment of the said movable platen assembly with respect to the said main frame.
Claim 11
Dependent Claim
47 words
A wheel press according to claim 9, wherein said equalizing means comprises a positively acting mechanical assembly interconnected between said movable platen assembly and said main frame and arranged to positively counteract any tendency of mis-alignment between the said movable platen assembly and the said main frame.
Claim 12
Dependent Claim
132 words
A wheel press according to claim 10, wherein said equalizing means includes a pair of shafts which extend along the said movable platen assembly in parallel spaced apart relationship remote from the said press surfaces, said shafts being fixed to the movable platen assembly for rotation about their longitudinal axes and being provided at each end with a sprocket or gear or the like fixed thereto, each of said sprockets or gears being arranged to engage with a length of chain or gear rack fixed to the main frame assembly in parallel relationship with the direction of movement of the said movable platen assembly, and wherein misalignment at one end of said one platen assembly is counteracted at the other end of said one platen assembly by torque transmission through said shafts.
