type of lock?

Dec 18, 2004 9 Replies

I have old victorian doors in my house. They have locks which are screwed onto the door rather than cut into the door.



Any idea what these are called? I would like some new brass ones.­ ­­ ­


Rim Sash Locks. Screwfix sell the brass ones at £9.99 cat no. D6756-63

Don.

Glynwebb in Bradford have some brass ones for a tenner, seen them much more than that though

Just the facts please...

Interesting site, there are 2 "real" problems with 4x4s... o Miss-match of bumper height:

---- with *older* crash barriers (4x4 can somersault over)

---- with *a fair number* of cars (4x4 above car crumple zones) o Some have poor suspension/tyre/inflation combinations

---- Many of the problems can be resolved or minimised

Interesting, because there are 2 "real" problems with cars... o Crash testing is somewhat unrepresentative

---- side-sled too low -- over-utilising sub-frame & sill box

---- non identical car impact -- heavy car hits a small light car

---- car survival space (rather than G alone) is often a problem o Some have poor suspension/dampening combinations

---- several cars suffer notable toe-out on off-camber corners

-------- especially decreasing radius on/off ramps (not just TTO)

---- many cars have under-damped suspension

-------- in a slalom the suspension oscillates (compression, jounce & rebound)

-------- in a decreasing-gap-slalom under-dampening causes early full-jounce

-------- early full-jounce is near infinite spring-rate early in weight transfer

-------- so weight transfer crushes the front suspension & violently flips the car

Few normal driving situations replicate a decreasing-gap-slalom, you simply don't do enough oscillations to get to the early full jounce in weight transfer. However badly designed Autox courses, or test-drivers "demonstrating" on small areas of dry tarmac can get a nasty surprise - high-end cars included.

Neither vehicle type can defy the laws of physics, both can defy good design :-)

Look out, here's another one of those OE users again! ;-)

Actually you were right, it is OE: o Outlook is my mail client o Outlook has no news client, so uses Outlook Express

I switched to Outlook since the OE dbase corrupted and the usual recovery tricks failed - but ironically Outlook imported ok.

FreeAgent was never this much trouble.

Erm, that's why I said it!

I'd use that then if I were you.

I don't know the quality of the ones posted about here but typically council houses were supplied with something like these things not all that long ago.

They'd have a halfway decent front door lock but around the back (where no one can see you're being burgled) one of those teo lever victorian things.

Make sure that the lock you get is a five levered affair. Typically the cheap locks on sale these days are more trouble than they are worth.

We had a number of threads on here about locks failing about a year ago. (Stock of crap imports from a country whose populace in or out of prison is slave labour no doubt.)

They were all the same problem I believe. Not that they were rims of course.

I think the style you are after is a far more secure one than mortice locks which reqire the removal of a substantial segment from the middle of the most easily smashed portion of a door.

Rim Locks. We sell cheapies (Sterling) and decent (Legge), both are identical apart from the price. They offer virtually no security so if that's a concern get a decent mortice lock or a BS rated yale type thingy. ­

Silly lad, take em down to a proper locksmiths and get them to make keys for it. You dont need original keys to copy, as long as you got to a place where the locksmith knows one elbow from the other.

Clean up the old ones and you'll have a lock that should last another

100 years, and be original too. Just silly to remove them and fit lightweight replacements, at greater parts and labour cost.

If you must remove them for reasons unknown, send em to me.
