PROVISIONAL SPECIFICATION.
Improvements in Decorated Glass Door Knobs or Handles.
1 ERNEST LE LACHEUR of Cambridge Park Saint Peter Port Guernsey Jeweller
do hereby declare the nature of this invention to be as follows:-
1
The objects of this invention are to enable glass door knobs or handles to be decorated
in such a manner that the decoration is permanent and not liable to be rubbed off or
otherwise damaged, and also to enable the knob to be decorated so as to match the
glass finger plates on the door.
According to this invention I make the door knob in two portions either entirely of
glass or partly of glass and partly of metal or other suitable material. I also form
the front portion (which must always be of glass) with a cavity at the back thereof &
I decorate the said cavity by painting gilding silvering or otherwise as desired. I
then fasten the aforesaid front portion of the knob to the back portion thereof which
fits the spindle passing through the lock and is secured thereto in the usual way.
I secure the glass front portion of the knob to the back portion thereof by means of
cement spinning a flange on the latter when of metal down on to the glass front or
by other suitable means.
144
I prefer to make the aforesaid cavity in the glass polygonal instead of circular and
to form a boss fitting the said cavity on the back portion of the knob so as to ensure
this portion turning with the glass front portion in the case of knobs other than
circular outside this is unnecessary.
This invention is particularly applicable to the manufacture of door knobs to match
decorated mirror finger plates.

be performed, to be particularly described and ascertained in and by the following
statement:
The objects of this invention are to enable glass door knobs or handles to be decorated
in such a manner that the decoration is permanent and not liable to be rubbed off or
otherwise damaged, and also to enable the knob to be decorated so as to match the
glass finger plates on the door.
According to this invention I make the door knob in two portions either entirely of
glass or partly of glass and partly of metal or other suitable material. I also form
the front portion (which must always be of glass) with a cavity at the back thereof

I then fasten the aforesaid front portion of the knob to the back portion thereof
which fits the spindle passing through the lock and is secured thereto in the usual
way. And in order that my said invention may be the better understood I will

portions turning together in the case of knobs other than circular this precaution is
unnecessary:
