Industry Pioneers: Peter Ellis - the Father of the Paternoster


Peter Ellis was born on 1 August 1805 at Shaw's Brow (later renamed William Brown Street) in Liverpool. He was the third son in a family of seven; his parents were Peter Ellis Senior and Ann Ellis (née Appleton). Peter Ellis Senior was an architect who worked on the construction of Courts in an area now buried under Lime Street Station. It was perhaps no surprise when Peter followed in his father’s footsteps and became an architect. He was first mentioned in Gore's Liverpool Directory in 1834 as an architect with an office on Renshaw Street but prior to that he had learned his trade working with his father developing terrace properties for residential use. 

What did he do?

Ellis had a fairly prolific career and worked on many buildings in the Liverpool area in from the 1820s right up 1884, the year of his death. He died at the age of 79 at his home at 40 Falkner Square on 20 October 1884. Of all the buildings that he worked on he is best known for two of his commissions; Oriel Chambers built in 1864 and 16 Cook Street built in 1866. The Cook Street building had a spiral staircase, cantilevered out from the main building and clad with sheets of iron and glass. Oriel Chambers took its name from the type of windows used was in the construction. Oriel Chambers became Ellis’ most notable contribution to the architectural community in the United Kingdom and around the world. Oriel windows are a type of bay window that project from the main wall of a building but do not reach the ground. Oriel windows are supported by corbels, brackets or similar and are most commonly found projecting from an upper floor but have also been used on the ground floor. 

How does this relate to the Vertical Transportation industry?

Designed and built by Ellis, Oriel Chambers contained the world’s first Paternoster-style lift. Ellis received a lot criticism from the architectural community for Oriel Chambers at the time of its construction and his career suffered a loss of momentum.  Many years later Oriel Chambers was praised for being one of the first office buildings to use an iron framework structure and oriel windows and Ellis was finally acknowledged as a pioneer. The innovative design has also been recognised as a precursor to Modernism and a source of inspiration for John Root’s early Chicago skyscrapers. From a vertical transportation perspective, Ellis is recognised as the Father of the Paternoster lift.  Ellis had filed a patent* for a ‘continuously moving lift’ in 1866, it was granted the following year and the Paternoster lift at Oriel Chambers was installed in October 1869. Paternosters went onto become very popular during the first half of the 20th century, particularly in Eastern Europe. You can read more about paternosters in our post, ‘here’.

Spotlight on Innovation: OTIS GeN2 Switch Technology


In 2014 Otis released the Switch elevator powered by patented GeN2 technology. The machine is pioneering in terms of its energy efficiency and ease of installation. Its highly efficient and compact qualities make the GeN2 Switch best suited for use in residential buildings, especially those that were built without an elevator.

How does the GeN2 technology work?

The GeN2 uses flat polyurethane-coated steel belts instead of the traditional steel ropes. They are 20% lighter and last three times longer than traditional ropes. The polyurethane-coat finish also serves to make the belts more flexible, which allows them to bend tightly around small diameter sheaves. This superior flexibility allows for a more compact gearless system that is 50% more energy efficient than a conventional machine.

What are the benefits of the GeN2 Switch elevators?

One of the clearest benefits of this machine is its energy efficiency. The GeN2 Switch elevator uses an electronic-battery pack to power the machine, the battery pack is charged by energy generated by the elevator when it is in use. When the motor is idle, the electronic -battery pack recharges and prepares to power the motor when it next comes into operation. This system produces significant savings to electricity bills. The electronic-battery pack also enables the elevator to continue in service in the event of a power failure, the elevator can make up to 100 trips after the power has failed.

The elevator has less movable parts than a conventional machine and provides a very comfortable ride for its passengers. The gearless system means there is minimal noise when the elevator is being operated. This benefit, combined with the fact that the GeN2 requires no specific electrical installation, makes it a great passenger lift system for residential buildings. The compact machine can be plugged in like any other electrical appliance in the building using a single-phase 220V power supply; making installation easy and affordable.

Compared with other conventional systems, the GeN2 also ranks highly in terms of environmental protection standards. The polyurethane-coated steel belts remove the need to lubricate the machine’s parts, thus avoiding the need for hazardous wastes.

Should the Paternoster lift be confined to History?

The paternoster lift takes its name from the first two words of the Lord’s Prayer - “paternoster,” or “Our Father” in Latin. The image of a moving chain decorated by small, individual compartments reminded its designers of rosary beads being turned in people’s hands whilst praying, which is how it got its name. The first paternoster-style lifts were installed in Oriel Chambers, Liverpool in 1868 and were designed by the architect Peter Ellis. In 1876 a German company R Stahl* installed a paternoster London’s General Post Office. However, in 1877, British engineer Peter Hart obtained a patent on a paternoster design. Then in 1884, the Dartford, England, engineering firm of J & E Hall built its "Cyclic Elevator”. Paternoster lifts comprise of a chain of open compartments (each usually designed for two persons) that move slowly in a loop up and down inside a building without stopping.

Where was the Paternoster lift popular?

Paternoster lifts were popular in Europe during the first half of the twentieth-century, but their use led to numerous health and safety concerns. These concerns were understandable. The fact that paternosters do not stop means they are particularly dangerous for the elderly, disabled and children to use. Add to this the fact that paternosters are door-less and it is easy to appreciate how accidents could happen and unfortunately they did happen and some included fatalities. Riding a paternoster is no time to be staring at your smartphone; timing your steps on and off the lift demands total concentration. The poor safety record of paternosters has led to them being described as ‘death traps’ in some circles.

When was the Paternoster lift banned from manufacture?

By the 1970s this poor safety record led to new paternoster installations being banned in many countries across Europe. Germany banned new installations of paternosters in 1974. In recent times government initiatives to remove the remaining 250 operational paternosters in Germany have met with a fairly surprising public backlash. Supporters of paternosters claimed they had efficient design and perhaps nostalgia caused them to overlook safety concerns. In the UK British National Standards Related to Lifts, Escalators and Moving Walks were updated with BS2655 Part 5 in 1970 that specifically outlined safety requirements for paternosters. All of the UK’s paternosters in service had been constructed before BS2655 Part 5 was introduced. 

Did any manufacturer ever improve upon the design?

In 2013 Hitachi introduced a design for a Circulating Multi-Car Elevator System that appears similar to a paternoster but has two additional benefits – the lift cars are independent of each other and are able to stop like conventional lifts. In the Hitachi prototype lifts are counterweighted against each other. You can see the set up here 

Safety first: Yes, Paternosters should be confined to history?

Given the number of accidents that have occurred with passengers travelling on paternosters it seems sensible that they are confined to history. It is extremely unlikely that new paternoster installations will be constructed anywhere in the world. It remains to be seen whether architects and building contractors have any appetite for paternoster –style vertical transportation systems such as the Circulating Multi-Car Elevator System designed by Hitachi.

However, contemporary multi car systems, as designed by TKE, may be given the name of paternoster as a ‘modern variation’ on an old theme.

Industry Pioneers: Dr. Joris Schroeder and the Miconic 10




Little is known of Dr. Joris Schroeder’s early life and upbringing and no details emerged after exhaustive searches on the most popular search engines. What is clear is that Dr. Joris Schroeder had a huge impact on the vertical transportation industry particularly with regard to one specific invention but we will return to that later. He also impressed Peter Boardman on the subject in terms of its relevance to the future of lift control systems.

Career


There are more details available regarding his career. He was a graduate of Stuttgart Technical University and received a Ph.D. from the Berlin Technical University. He achieved the position of Vice President of Corporate Engineering and then Vice President of Product Research with Otis in Germany and then also in New York, USA.  In 1977 he left Otis and joined Schindler in Switzerland as a member of their Corporate Executive Committee and his remit included: engineering, production, construction and service. He passed away in the early 1990’s.

His Body of Work

During his career Dr. Joris published a number of industry leading articles and white papers including The Energy Consumption of Elevators published in 1980. If you read the piece it’s easy to appreciate that he laid the foundation for what was to come later. In 1985 he first wrote about ‘Destination Dispatching’ in the July edition of Elevator World and he followed this up in 1990 with the publication of an article in the March 1990 issue of Elevator World entitled "Advanced Dispatching" ("the Schroeder Article").

Why is Dr. Joris Schroeder so Significant?

Dr. Joris Schroeder’s contribution to the vertical transportation industry was more than theoretical, though. In 1990 he was granted a patent for the Miconic 10 along with Dr. Paul Friedli (also from Schindler). Using microprocessors Schroeder created Schindler’s Destination Dispatch system – what we now call Destination Control. The first building to install the Miconic 10 system was the Hamburg Electric Company in Germany in 1990. The first installation in the USA was in 1993 at the Ameritech building in Indianapolis.  As architects, building contractors and the public came to understand these new ‘smart button-less’ elevators their popularity grew. Energy efficiency was also 30% better with the new Destination Control elevators. Schindler, under Dr. Friedli’s guidance have progressed with the development of M10, now known as their Port system which has the ability to interface with other building elements, i.e. speed-gates and door locking systems.

All lift companies now have Destination Control systems so this idea can be seen as transformational. D&B have been specifying these systems enthusiastically for years and as a Consultancy can be considered to be leading the way.

Spotlight on Leeds

Dunbar and Boardman first opened a Leeds office during November 2002 in Westgate House at 100 Wellington Street in the city centre. The first project that the office worked on was Tower House Leeds now known as Tower North Central.  Tower North Central is a 77 metre high office tower with 20 floors situated at the top of Leeds city centre on Merrion Way close to the Merrion Centre.  Initially constructed in 1967 it was refurbished during 2003-2004 and now provides 76,800 sq. ft. of office space. The refurbishment included modernisation of a four-car group of passenger lifts for Jones Lang LaSalle.

Many other projects followed including the HBoS HQ Halifax. That was a project that necessitated the modernisation of 12 passenger lifts. In April 2013 as a consequence of our business growing we moved the short distance from Wellington Street to Wellington Place.  Below are a few of the projects that we have completed recently:

Asda - We completed a number of stores for Asda in 2014 including their new Mosborough store near Sheffield. That project required:  3 x moving walks, 2 x Passenger lifts, 1 x DDA platform Lift & 1 x Dock Leveller. All installed by Kone Plc.


Wm Morrison Plc
– During 2014 we also completed a number of stores for Morrisons including their new Weybridge store. Two moving walks and two passenger lifts were installed at their Weybridge store.

Bradford Royal Infirmary - D&B drew up the specification on behalf of Bradford Teaching Hospitals NHS Trust. The project required the installation of 1 x 2500Kg 33 person Bed Evacuation Lift including a modular lift shaft. Pickering's Lift won the tender to manufacture the lift; Traditional Lift Products constructed the modular shaft. The lift equipment was installed within the shaft modules by Pickering’s at TLP’s factory unit in Knowsley. The five storey lift shaft & lift equipment was installed in 3 days.


Do you have a current or planned project in the Leeds area? We would be happy to discuss any such requirements and how we may be able to assist. Please contact us via our Leeds Office and ask for Paul Hastings to start the conversation. We look forward to hearing from you.
