Papers of Anthony George Maldon Michell [1920-1970]
Creator(s): 
Michell, Anthony George Maldon [1870-1959]

Technical drawings from Crankless Engines Ltd, 2515 in number. See also reference number 1991.0074 University of Melbourne Department of Civil Engineering for more on Michell.
Most of the drawings are identified by an engine number (CE…), part number (often several on each item), and drawing number that usually corresponds to a chronological order. Drawing numbers that begin with the letters “SK” usually correspond to sketches, proposed or draft plans. Three drawings have drawing numbers that begin with “MC”, which appear to be designs associated with the University of Melbourne rather than Crankless Engines, Ltd. Some plans have been given a job number rather than an engine number, but this seems to be simply an earlier version of the same filing practice,
phased out in 1922.
Those plans that have not been given a CE or part number but have been
given a drawing number are usually plans of the general arrangement of a
particular engine, named in the title, although there are exceptions to this.
The company name changes around 1924 from Crankless Engines (Aus) Pty
Ltd to Crankless Engines Limited, although there is considerable overlap around that. Apart from showing the change in company status to a publicly listed  company, there does not seem to be any other significance attached to that identifier. The date range usually refers to the date that the plan has been drawn (earlier date) and the date that it was approved (later date). A number of plans were cancelled, and revised plans drawn to replace them. These have been noted in Scope and Content.
Plans that were drawn or traced by AGMM (Michell), PEI (Irving), RWGM, JWS or TLS have been noted as such because they are noteworthy persons. Blueprints have also been noted. Some items are missing particular descriptors, because those descriptors were
not provided on the item itself. Unless otherwise stated, measurements are in inches
There are a number of brochures, reports and a photograph attached to the
collection that do not seem immediately connected with AGM Michell, although loose associations may be inferred from the historical note. The collection also contains photocopies of agreements made with Michell or Crankless Engines, Ltd.
