Lamp

A lamp of moderator or tilt model, likely manufactured during the latter part of the 19th century. The lamp is made of brass and has a white porcelain shade with a ribbed surface. The porcelain shade is missing a piece in the upper edge. The height of the lamp is adjustable and regulated by a screw.

A moderator lamp has a spring that can operate in two ways; either it sets a clockwork in motion that drives a small pump to raise the oil, or it does this directly without a clockwork. If it does not have a clockwork, there must be a special regulator, a moderator, used to ensure a steady oil supply. Hence the name ‘moderator lamp’.

A tilt lamp is a lamp with a tilting bottle, that is, a flask-like oil container. This oil container can be tilted, hence the name, and releases the oil with the opening facing downwards. It has the same opening for refilling and draining. This lamp was acquired by the City Museum in 1907 as a purchase from Hilda Pettersson.
