Abstract
A brick-cutting machine having an axially rotating reel with sets of radially disposed, spring-tensioned cutting wires is equipped with resiliently compressible, rubber cushion blocks or pads positioned to cushion and limit rebounding movement of the wire-tensioning springs and thereby prevent the application of excessive and destructive tension forces to the cutting wires of the reel.
Claims2
In a brick-cutting machine having an axially rotatable reel which includes a multiplicity of axially rotatable inner hub plates, a plurality of axially extending, outer support bars disposed in radially outwardly spaced relation to said inner hub plates, and formed with a plurality of longitudinally spaced slots, a multiplicity of U-shaped bow springs carried by each of said support bars and having resiliently flexible free end portions extending through and movable within the slots formed in said bars, and a multiplicity of radially disposed cutting wires carried in tension between said hub plates and the resiliently flexible free end portions of said bow springs;
- that improvement which comprises a resiliently compressible cushion block carried in each of the slots of said outer support bars and arranged to limit rebounding movement of the free end portions of said springs within the slots of said support bars.
