Abstract
A throwing wheel comprising a mounting element having a central axis with a plurality of blades connected to the mounting element. Each of the blades has an inner end, a first portion of said inner end and a second portion of said inner end. A plurality of locking mechanisms is associated with the respective plurality of blades. Each of the locking mechanisms comprises at least one biasing element which biases the blade away from the central axis of the mounting body and connects each of the blades to the mounting element.
Claims28
A replaceable abrasive throwing wheel assembly blade comprising:
- a body member having an inner end, an outer end, a front surface, a rear surface, an inlet end and an outlet end;
- a first portion projecting from the inner end of the body member and receiving and engaging a biasing element;
- and
- a second portion, spaced from the first portion, and projecting from the inner end of the body member, the second portion engaging the throwing wheel assembly and being biased against disengagement by the tension of the biasing element engaging the first portion.
An apparatus comprising:
- a mounting element having a central axis of rotation;
- a plurality of blades detachably connected to said mounting element, each having an inner end, a first portion of said inner end and a second portion of said inner end;
- and
- a like plurality of locking mechanisms associated with the respective plurality of blades, wherein each of the locking mechanisms includes at least one biasing element, biasing said blade away from the central axis of the mounting element and detachably connecting each of said blades to said mounting element along said inner end.
A method of attaching a blade having a biasing element, a first portion and a second portion to a throwing wheel with a mounting element comprising the steps of:
- compressing the biasing element with the first portion of the blade to urge the second portion towards the mounting element;
- engaging the second portion of the blade with the mounting element;
- and
- releasing the biasing element from compression to detachably affix the blade to the throwing wheel.
An apparatus comprising:
- a means for mounting an element, said means for mounting having a central axis;
- a plurality of blades detachably affixed to said means for mounting, each of the blades having an inner end, a first portion of said inner end and a second portion of said inner end;
- and
- a plurality of means for affixing each of said plurality of blades to said mounting element, wherein the affixing means further comprises a means for biasing said blades away from the central axis of the mounting body.
