Anyone measuring a good few feet distance will be aware of Chestermans tapes for which James Chesterman is famous, less famous are his single and double action door springs.
Today I would like to introduce readers to another of Hill and Hodges floor springs that being Hill and Hodges Patent Check Action.
This one comes from the Quaker House in the village of Bournville, the village set up by George Cadbury. A car had hit the doors these were fitted to...more to come.

I have mentioned The Wallace previously, manufactured by Edwin Showell & Sons (another Birmingham based door spring manufacturer) so this will just be a quick post. The owner of The Wallace had a problem with it, when the door it was connected to was opened 90 degrees, no problem but when the door was only opened 15 to 20 degrees and let go, it slammed (although it didnt if the door was held for 30 seconds or so). This was obviously a concern to our customer so he brought it to us for investigation after having taken it to a couple of other places and had a go at modifying the piston himself.
After some investigation it was noted the piston and oil intake were in our opinion manufactured in such away it was never designed to have control if the door was only opened a little way.
We therefore changed the configuration, designing a bespoke one way valve, manufacturing it and used it in conjunction with the original system. You can see the valve was incorporated into the head of a "manufactured" bolt in the picture, this was not the first design, we were going to place a new valve into the piston itself but this was decided against for a number of reasons.
The Wallace now has control from 1 degree, through and up to 90 degrees instantly.
Investigating alternatives before coming up with the solution.
As always comment if you care to.
In this blog entry I would like to introduce readers to George Beattie, who on July 6th 1848 was granted a patent for his Improved Air Spring, that relied on a vacuum one side of the piston and atmospheric pressure on the other side to control the action of a door, having no springs whatsoever in its innovative design.
Reproduced below is George Beatties description of his wonderful door spring found on page 295 t0 296 of The Civil engineer & architects journal, Volume 13.
In this blog entry I would like to push the date for the earliest door spring back even further to 1748, which I am sure readers will agree this is quite along way from the Henry Downer patent that I have mentioned many times previously and our Mr Smith. The actual date is even earlier than this because it can be reasonably presumed it was manufactured before the date of the letter between the two brothers.
I discovered reference to this door spring in a correspondence between Sir Edward Filmer (3rd Bart) and his brother Beversham Filmer on the 13th of October 1748 via the National Archives online.
"Filmer Manuscripts. CORRESPONDENCE. Sir Edward Filmer (3rd Bart.). Letters from his brother, Beversham Filmer. From his brother, Beversham Filmer. About sending a door spring having a watch repaired and music he had left at East Sutton
Held by: Kent History and Library Centre Date: 13 October 1748 Reference: U120/C28/43"
Obviously I have no pictures of this door spring but please feel free to leave a comment if you found it interesting.
I have recently discovered, many emails from various places that for some reason I seem not to have received. This was an inquiry I discovered about the humble Briton B which of all places is on a door in Antartica in Sir Edmund Hillary;s TAE/IGY Hut which eventually grew into now what is called the Scott Base and represents the beginnings of New Zealands involvement in Antartica.
I was contacted on the phone by Martin Wenzel who was there with the Antarctica Heritage Trust and always wondered why I had never heard from him again. Here are the shots he sent me of the well traveled Briton B.
Martin if you ever read this I can only apologise.
In 1872 Robert Lawson designed the Knox Church in Dunedin in the 13th Century Gothic Style, the second Church on that site as a more permanent place of worship for those seeking fortune in New Zealands biggest gold rush for the sum of £17,757.
In or around the 1970's James Gibbons supplied the floor springs used in the buildings Halls.
In 2019, I have been contacted by Dr Chris Bloore to help with the source and supply of a strap insert for the broken one as can be seen in the picture below.

I know many believe that it was an American, Lewis. C. Norton who invented the first door check and many places on the internet will uphold this by telling the story of how Lewis was employed by the Bishop at Boston Trinity Church to invent a device to stop the slamming of swing doors in the vestibule (17 June 1881). However this is not the truth it was in fact an English Father and Son team by the name of William Ovenden Snr and William Ovenden Jnr in April 1864.
If you turn to page 111 in the Patents for Inventions of Specifications relating to Hinges, Hinge Joints, and Door Springs at the bottom of the page you will find an entry entitled 'A.D. 1964, April 15 - No 948 Ovenden, William, the elder, and Ovenden, William, the younger - Certain mechanical arrangements to be applied to doors and casement windows to prevent slamming or "clapping."' It goes on to describe the very first hydraulic and pneumatic door check (as can be read below), beating Mr Norton by 17 years. Below is the entry -
Thank you for taking the time to read my blog and feel free to comment.
As I have recently discussed the Great Exhibition of 1851 held in the Crystal Palace at Hyde Park, I thought I may share a little about the other door spring manufacturers that exhibited in front of Queen Victoria and 6 million others. Along with Thomas Turner another of the famous manufacturers displaying their door springs was William Newman of Newman/Tonks fame.
In addition to his door closers he also displayed a unique machine that tested door springs known as the The Pediatricas.
As you can read it ended up at the bottom of the Grand Union canal but was fortunately retrieved in 1968 according to the Coventry Evening Telegraph of Wednesday 28th of February (1968). How it got there nearly one hundred and twenty years after being first displayed at the Great exhibition is a mystery that I have yet to find the answer to. Here is a link for readers wanting to know a little more about the 1851 Exhibition - https://www.historic-uk.com/HistoryUK/HistoryofEngland/Great-Exhibition-of-1851/

Many I am sure, of a certain age, will remember seeing the heavy cast iron scales outside of chemists where for a small fee you could weigh yourself, or possibly you have heard of the name Salter because you have a traditional grocers scale in your kitchen with the name Salter across the dial? Less people, I expect however will know that they were also manufacturers of door springs and pneumatic door checks as can be seen in the advert above.
As you can see the Turner and Co door spring previously spoken about from a certain castle in Windsor is in a sorry state of repair, possibly to be expected as I believe these particular in floor door closers are from around the 1850's meaning they are nearly 170 years old.
Above is the divider mark.
Above you can see J. Barrow (John Barrow)
The remains of the leather bump stops.
Setting up to braze the broken bronze parts.
As you can see they are coming along, although there are a number of issues to contend with.
Readers should be able to see the signs of the bespoke manufacture of the various parts that make up this fantastic in floor door closer.
As discussed previously this particular floor spring has both the markings of Barrow and Turner (John Barrow) and Turner & Co (Thomas Turner), meaning it must have been manufactured in the transitional period between the ending of one partnership/business and the beginning of another.
Below is information taken from the Official Catologue of the Great Exhibition of the works of Industry of All Nations (1851), as you can see T. Turner exhibited at the now famous Crystal Palace. I wonder if it was this model door spring and centre he exhibited?
Readers should see there has been a lot of effort put into getting these back to good health (well worth it considering their age, their historical importance and their home of course) including the manufacture of a number of bushes, sleeves, transfer arms, cog and rollers. It should also be noted the four names/businesses surrounding these two spring floor hinges, J. Barrow, Turner and Co, Turner and Son and Barrow & Turner.
A new cog was cut for the Turners.
As always I look forward to any positive comments made on this or any of my previous blog posts.
As there is so little information out there with regard to door closers, especially vintage and antique model floor springs, I thought I would start this blog.
