Heenan and Froude dyno DPX 1
« on: August 10, 2013, 09:19:22 AM »
Can anyone help me out ? I am looking for a manual for a Heenan and Froude DPX 1 dyno which I picked up in bits ,a bit of a jigsaw puzzle but got it  back together . I beleive they can be altered to run up to 12000rpm would be good to have a dyno to play with and test future CB500 4 race engines ????

Did you know that Heenan and Froude built Blackpool Tower.

The Blackpool Tower Company was founded by London based Standard Contract & Debenture Corporation in 1890, when it bought an Aquarium block on Central Promenade with the intention of building a replica Eiffel Tower on the site. John Bickerstaffe, a former Mayor of Blackpool, was asked to become Chairman of the new company and its shares went on sale in July 1891. The Standard Corporation kept 30,000 £1 shares for itself and offered £150,000 worth of shares to the public, although initially only two-thirds of these shares were taken up. This lack of interest forced the Tower Company to ask for further cash contributions from its existing shareholders, but the poor financial situation of the Standard Corporation, worsened by the falling share price, rendered it unable to pay. Bickerstaffe’s remedy for the potential collapse of the venture was to buy any shares available, until his original holding of £500 amounted to £20,000. He also released the Standard Corporation from their share commitments. When the Tower opened in 1894 its success justified the overall investment of nearly £300,000, and the Company made a £30,000 profit in 1896.[2]
Two Lancashire architects, James Maxwell and Charles Tuke, designed the Tower and oversaw the laying of its foundation stone,[3] on 29 September 1891[4] with a time capsule buried beneath it.[5] By the time the Tower finally opened on 14 May 1894, both men had died.[3] Heenan & Froude of Worcester were appointed structural engineers, supplying and constructing both the main tower, the electric lighting and the steel front pieces for the aquariums. A new system of hydraulic riveting was used, based on the technology of Fielding & Platt of Gloucester.[6]
The total cost for the design and construction of the tower and buildings was about £290,000.[5] Five million bricks, 2,500 tonnes of iron and 93 tonnes of cast steel were used to construct the tower.[7] Unlike the Eiffel Tower, Blackpool Tower is not free-standing. Its base is hidden by the building which houses Blackpool Tower Circus. The building occupies a total of 5,050 square metres (54,400 sq ft).[1] At the summit of the tower there is a flagpole.[8]

Sorry for the bad info. I did find a chart that showed HP and RPM ratings for the different models that showed the DPX1 to be a max of 100 HP and an RPM range of 5000-9000 RPM. I also found an interesting article from 1921:
