Hipp Clock with Prolonged Impluse

[Ernest JensonParticipant @ernestjenson72122]

I live in California and I purached a Hipp Clock on eBay that came from England that was reported to be a project in the Model Engineer in the 1930s. I completed the project about five years ago and it has been running ever since. I am wondering it archives exist and if there is an article on building "A Hipp Clock with a Prolonged Impluse" and if a copy can be obtained.

Ernest,

You may find this list useful.

If you could post a few Photos, that would help with identification.

Hi Ernest

I note Michael's post and have a copy of John Wilding's design for them Hipp Toggle clock. It is on my " things to make" list and I have all the components in a drawer awaiting machining. Sadly I've several drawers like that! What is the " Prolonged Impulse" you mention?

Related to the Hipp Clock – I live in Devon and, in the National Trust property, Castle Drogo – built by Julius Drewe in the early part of the 20th century, there is an example of the Hipp Toggle clock very similar to Wilding's design. Drewe was very interested in the "new" electricity and many new ideas (for that time) can be seen there.

Regards

Ernest – I find 37 articles on 'Hipp clock' listed in ME from 1905 to 2007. Only 1 has a reference to a prolonged impulse. Volume 104, #2614, pages 835&36 written by A.S.Prescott of South Aferica in 1951. The complete list is here – http://www.itech.net.au/modelengineer/ME_Response.aspx

Ernest,

There is a scanned copy of the "ME Jubilee Clock" articles, available here.

Probably not exactly what you have, but well worth reading.

I have added pictures in "My Photos" of the clock. When I received the clock, it was not finished but very old with the case cracked from age, glass broken and pendulum stick missing. I got the pendulum swinging but there was no provision for running a clock movement. I decided to use a photo cell and make an electrical circuit to out put a pulse to a slave clock. Later I intended to build a mechanical movement as exists on a very old Hipp clock that I have but am still using the slave as shown in the pictures. The clock is listed in Chapter 12 of Hope-Jones book " Electric Clocks and How to Make Them" and in "Electric Clocks and Chimes"(Model Engineer Handbook Series reprinted by Lindsay Publications Inc). I will follow up on information provided to me by ellis and others. I will take a picture of the pendulum coil and magnet and include it in "My Pictures" as it is interesting.

Thank you very much,

Ernie

Thanks for posting the photos, Ernie

I will dig-around, and let you know if I find anything.

P.S.  If you have close-up facility, would you please include a detail of the "toggle" mechanism that operates the switch.   … Many thanks.

Master clocks using the Hipp Toggle principle were extensively employed by the GPO, not just to drive slave clocks, but to provide timing and control pulses for telephone exchanges and systems. There is quite a bit of information and some interesting pictures HERE

Look especially at the type 36 and 46 master clocks.

Michael – a typical movement and description of its operation is shown HERE

Now that was a trip down memory lane!

Norman

Note: That was in the hope that it would aid identification of the "project"

Michael, I have downloaded another picture of the Latch and Unlatch. The way it works is that the toggle depresses the beam. The latch on the right side captures the beam and keeps it in the lower position. When in the lower position the contact is closed which is on the lower left. When the pendulum moves to the right about as far as it is going to go due to the magnetic impluse the pin on the pendulum bracket hits the red bumper and unlatches the beam which open the contacts. The round magnet bar passes through the coil and gets a rather good impulse. With 12 volts, the pendulum will swing about 20 times before the toggle drops into the vee again, lataching and closing the contact. I figured that this might be a good idea so I wanted this to be a free pendulum, free from the work of moving the works. That is why I used the photo cell and the PC board to drive a slave clock.. That article on the Julibee Clock is very good. I am going to read it again very carefully. I expect that the book "Electric Clocks and Chimes Model Engineer Handbook Series" is an exact reprint from the article that we may find in the magazine. That article is 43 pages long with all the drawings. I will scan it and email it if anyone wants it..

I don't know what a PM is. Please explain so I can read, Norman, I am familar with a GPO as I have been working with my friend who has one comparing it with my Model 35 IBM master clock. so far the GPO has been better. We send information back and forth from our MicroSet timers. Google MicroSet and in the footnote you will find reference to the work we have been doing restoring a Tower Clock in Santa Barbara. Also check out http://www.nawcc-ch190.com and look at our newsletter and you will find out what the Yanks are up to in Southern Calif.

Thanks for all the help, Ernie

Ernie,

Thanks for the additional photo, and descrption.

Whilst clearly related to Hipp's original design; that is an interesting variant. I'm sure that I have a copy of "Electric Clocks and Chimes" somewhere; but I cannot locate it at present. If you are happy to eMail PDFs of the relevant pages, that would be a great help.

I will send you a PM with my eMail address. [Note: At the bottom of each Post on the Thread, there is a facility to "Message Member" … this lets you send a Personal/Private Message direct to that Member … they are accessed via the "My Account" box at the top left of the page.]

Look forward to reading about your restoration of the Tower Clock

P.S. There is an interesting monitor of the clock's performance, here.
