Blaw-Knox, still in existence today as one of the most prominent manufacturers of road paving equipment in the world, was formed from 2 companies, Blaw and Knox. Originally a maker of steel concrete forms, as highway construction moved away from rigid concrete construction, the company began making highway pavers for the new method of flexible asphalt paving (tarmac).
This company sample book documents the company's products during the period they focused on concrete forms & associated construction projects... herein are 17 photographs showing the divers forms, while in use, produced by the company [e.g., "Light Wall Forms", "Extra Heavy Type 'C' Road Forms", "Sidewalk Forms", "Half Round Sewer or Conduit Form" & "Traveling Telescopic Rectangular Sewer Forms"], as well as 21 photographs of the divers buckets offered by the firm [e.g., "Foundry Type Single Line Bucket", "Dreadnaught Bucket", "Speedster Bucket" & "Bulldog Bucket"].
An uncommon primary source visually documenting this company's work product of almost a century ago.
