P.Lewis British Aircraft 1809-1914 (Putnam)
The Hammond Triplane was designed by E. V. Hammond and appeared at Brooklands in February, 1911. The pair of tractor propellers were belt-driven from the engine and the machine, which was tested by C. Howard Pixton, possessed a fore-elevator and ailerons of very broad chord on the upper wings.

FROM THE BRITISH FLYING GROUNDS.
Mr. Hammond's "mono-bi-triplane" has at length also reached the engine-testing stage. This machine is certainly a marvel of light construction, so light indeed that it looks at first sight quite inadequate to support the weight of engine and aviator, to say nothing of landing in the ever popular sewage farm. We hope he will surprise the tenants, who appear in the meantime to be somewhat sceptical.
