Historical Window fittings - Information

Window handles are relatively new fittings. In the past, windows were closed using surface-mounted mechanisms – the window handle activates the mechanism – with espagnolettes or rudder rods, latches or chain locks.
 
In the last century, concealed mechanisms became common, which were then fitted with handles and small rosettes. For this reason, we cannot supply historical models with a grid mechanism. If a grid mechanism is desired, we can only supply it at a high additional cost. However, the mechanism must be embedded in the wood under the rosette.
 
For outward-opening windows, check whether the olive does not hit the second sash, the setter or the frame when open. In such cases, either half olives or cranked models must be used, or other window fasteners: see espagnolettes or rubbers.

Examples historical Window olives

For box windows with a small gap between the outer and inner window, the olive base can be shortened and, in some cases, a tiltable window olive can even be supplied.
Lockable window handles can only be manufactured under certain conditions, namely if the handle allows for the installation of a lock cylinder with a diameter of 12 mm. For all other handles, only a lock case with a pressure cylinder can be used for locking instead of a rosette.

Window handles can be reworked in the following ways:
 
  • as olives on gearboxes
  • as pre-lubricators or lubricators
  • as handles on door signs and rosettes
 
For large tilt and turn windows, room door handles can also be used as half-olives. You can find some more window olives in the chapter on window mechanisms.
 
We only varnish the fittings upon express request, as no varnish is truly permanent. Over time, brass and iron fittings develop their characteristic patina and thus a charm of their own, which is always preferable to a crumbling layer of varnish. The available materials and surface treatments for a set can be seen from the abbreviations in the table above (drop-down button). We supply wooden parts for handles and entire wooden sets in ebony, grenadilla, rosewood, walnut, oak, ash, pear, plum or as desired. If there is a matching front door and interior door set for the olive, you will find cross-references in the catalogue in the form: HT – 1 as a reference to p. 1 in the chapter on front door sets.
