COMPLETE SPECIFICATION.
A Device for Trimming Oil Lamps or Stoves.
I, DAVID THOMAS DAVIES, of Sunnyside, Galveston Road, Putney, Gentleman,
do hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained'in and by the following
statement:-
This invention relates to a device for use upon oil lamps or stoves and is designed
to prevent the charred portions of the wick when the same is trimmed falling into
the gallery or into the interior of the wick casing and thereby preventing the
free access of air to the wick and giving rise to danger of explosion or the burner
taking fire.
In carrying the invention into effect I construct a metal tray of such dimensions
and of such form as to 'readily fit the various forms and sizes of burners.upon
lamps and stoves as at present in use. The tray which may be stamped, spun
or otherwise formed of thin sheet metal may consist of an inner or dished portion
the dishing being of such size as to readily fit the burner as aforesaid, and at the
base of such dished portion I form a ring provided with an upstanding rim or
edge to retain the charred portion falling therein. The plain metal at the top
of the dished portion I perforate with holes of a form and size to allow of the
projection therethrough when the tray is upon the burner of either a solid round,
square, circular, or other wick or wicks as the case may be, the trimming of the
lamp being effected by rotating the the tray when the charred portion will be
cut or sheared off either by the edges of the holes or by means of a blade provided
for the purpose.
In order that the invention may be the better understood drawings are appended
in which:
Fig. 1, is a plan of 'a tray designed to be used upon a
oblong wicks placed side by side.
Fig. 2 is a section of Fig. 1.
lamp provided with two
Fig. 3 is a plan of a tray to be used upon a lamp provided with a solid 'round
wick.
Fig. 4 is a section of Fig. 3.
Fig. 5 is a 'plan of a tray for use upon a lamp provided with a tubular round
wick.
Fig. 6 is a section of Fig. 5.
Referring to Fig. 1. A is the tray proper provided with an upstanding peri-
pheral edge B, and dished as shown at C, the dimensions and outline of such
dished portion being in accordance with the shape and height of wick casing.
E, F, are rectangular openings through which when the device is in position, the
ends of the wicks protrude and are cut by the blade G pivotally secured to the
top H and which blade is operated by means of the knob or handle I and may
be rotated about its axis J thereby shearing or cutting the charred portion from
the top of the wick and allowing the same to fall into the tray A.
In Fig. 3 the dished portion C is somewhat deeper and is provided with a

page_text: vertical flange C₁ upon which are formed three small pieces (2 of sheet metal
turned inwards and upwards at their ends and by which means the charred ends
of the wick is removed when the device is placed upon the wick and rotated.
In Figs. 5 & 6 is shown a device for trimming a circular wick and which con-
sists of two trays K K stamped or otherwise formed as shown in the drawings
the upper tray K' being united to the main portion K2 of the device by the two
pieces of metal L L which may be either formed when stamping the device or they
may be replaced by pieces of sheet metal or wire attached in any convenient
manner to parts K2 K¹.
It will be seen from the drawings that between the tray and the main
portion there are left two circular slots or openings M M through which a
portion of the wick protrudes when the device is pressed down thereon and when
rotated the edges of the slot remove the charred portion of the wick collecting
it on the tray K.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is: --
The device for trimming oil lamps or stoves whereby the 'charred portion of the
wick is removed and collected, constructed, acting, and operated substantially
as herein described and 'shown by the appended drawings.
Dated this 19th day of January 1899.
