Latch Locks

I have a question that I have been pondering on, on and off for a while.

If you were to say, go to B&Q and buy a 5 lever latch lock, you would find that the latch is at the top and the locking part at the bottom, however, if you look at the very old locks which are fitted into doors the latch is at the bottom and the locking part is on top.

Does anyone know why they were changed around?

Am afraid so, got a list of things to do in the house as along as my arm, but just can't seem to muster up the drive to do them, oh well.

take the door off and turn it the other way,hey presto all sorted :LOL:
no no no no no no, its not upside down, when Ive been in say, georgian, edwardian era houses they have the old black locks, which are about six inches in length, normally the doors have knobs as apposed to handles and the key hole is always above the handle or knob, the key hole is the right way around in the lock although it is above the hole where the axle slides through, so, no, its not upside down, i just wondered why they have changed.
Probably, because with the lock above, the handle may obstruct you turning the key.
I think he means a horizontal sash.

Keyhole backet about 2 inches. knob backset about 5 inches.

I might have a look at mine if i have nothing better to do tomorrow
