We WILLIAM BOWN of 308, Summer Lane, Birmingham, in the county of
Warwick, Manufacturer, and GEORGE CAPEWELL, of 17 Victoria Place, Potters
Lane, Aston, near Birmingham aforesaid, Machinist, do hereby declare the nature.
of the said invention for "IMPROVEMENTS IN MEANS OR APPLIANCES FOR TRIMMING
WICKS OF LAMPS OR FOR OTHER SIMILAR PURPOSES to be as follows:-
"
Our improvements relate to wick trimmers, for bicycle, domestic and other
lamps and consists firstly, in forming a frame handle and lever of sheet metal wire
or other suitable material to carry two cutting plates, one of which is moveable
and made to slide over or under the other plate whilst cutting, which said plate is
either stationary or moveable.
To the lever or other suitable part of the appliance, we attach an oscillating
piece or pieces in combination with a spring in such a manner that when the
plates are brought together for the purpose of cutting, the closer they approach
each other the greater the pressure thereon, thereby keeping the plates in close
contact with each other whilst cutting and preventing them from lifting.
Secondly in making the handles or levers detachable and sliding or folding in
such a manner that when the said bandles or levers are detached or folded the
Trimmer occupies but very little space and may be carried in the pocket or
small Bag.

Lane Aston near Birmingham aforesaid Machinist do hereby declare the nature
of our said invention for "IMPROVEMENTS IN MEANS OR APPLIANCES FOR TRIMMING

same is to be performed to be particularly described and ascertained in and by
the following statement ;-
Our improvements relate to wick trimmers for Bicycle, domestic and other
lamps and consist firstly in forming a frame handle and lever of wire, sheet metal
or other suitable material to carry two cutting plates, one of which is moveable
and made to slide over or under the other plate while cutting, which said plate is
either stationary or moveable-To the lever or other suitable part of the appliance
wo attach an oscillating piece or pieces in combination with a spring in such a
manner that when the plates are brought together for the purpose of cutting, the
closer they approach each other, the greater the pressure thereon thereby keeping
the plates in close contact with each other whilst cutting and preventing them
from lifting.
Secondly our improvements consist in making the handles or levers detachable,
or sliding or folding in such a manner that when the said handles or levers are
detached or folded the trimmer occupies but very little space and may be carried
in the pocket or small bag.
But in order that we may be more clearly understood as to the nature of our
said invention we will proceed to describe the drawings hereunto annexed, reference
being made to the figures and letters marked thereon.
DESCRIPTION OF DRAWINGS.
Figure 1. represents a top view and Figure 2. a vertical section of our.improved
means or appliances for trimming wicks of lamps or other similar purposes, with
the lover A. and handle B. extended and the two cutting plates C. D. open ready
to receive the wick to be trimmed-E. E. is the frame provided with clips a. a. for
guiding the moveable cutter C. in its backward and forward motion-The handle A
is hinged or jointed at F to two cars or projections formed on the frame E. and
after passing through the slot H in the cutting plate C. is secured at its upper end
to the bent spring G the other end of which spring is connected to a small roller b.
pressing on the moveable cutting plate C. and holding it in position on the
frame E-The handle B. works in ears N formed out of or in connection with
the frame E. and the lever A is jointed at J. which permits the lever A and
handle B. to be folded over on to the frame E as shown in Figure 3. thereby
reducing the bulk for carrying in a bag or otherwise-When in operation the
lever A. and handle B. are quite rigid the stops d. on the frame E. and stop con

page_text: the lever A. effecting this object-Figures 4. and 5. represent top and sectional side
views of Figures 1. and 2. showing the lever A. and handle B. closed or pressed
together in the cutting operation the lever A working against the front edge of the
slot H in the cutting plate C. shown detached at Figure 6. advances the same
cutting the wick in a very easy and ready manner after which by removing the
pressure from the lever A. it will open automatically and withdraw the cutter
plate C. as at figure 2.
Although we have described and exhibited the lever A and handle B. jointed so
as to fold into a small compass, nevertheless where space is not an object the
lever A. may be in one piece, and the handle B. formed with or rigidly secured to
the frame E. Figure 7. is an end sectional view of the frame E. cutting plate C.
and spring G showing the frame and cutting plate curved to suit the general form
of the dome of lamp burners.
Figures 8. and 9. represent top and part sectional edge views of a modification
of the wick trimining appliances last described in which it will be seen that the
lever A and handle B' are placed horizontally and not vertically as in the former
case, the forward motion of the cutting plate C' being produced and the wick
trimmed by pressing the lever A¹ and handle B¹ together as shown in top and part
sectional views at Figures 10 and 11. after the wick is cut by removing the
pressure from the lever A¹ the same will open automatically and the cuttor
plate C withdrawn into the position shown at Figure 8. by the action of the
spring G and rocking or oscillating arm or piece K-In this instance also the
lever A and handle B¹ are shown as jointed at L. M. respectively for the con-
venience of folding up as shown at Figure 12. but it will be readily seen that
where space is no object the handle and lever can be each in one piece, or the
handle and lover in both instances may be made to collapse, by sliding one part
into another.
Figure 13 is a detached top view of the frame El and cutter plate D¹.
Figuro 14. top and sectional views of the cutter plate C¹-Figure 15. top sido
and part sectional end views of the spring G₁ and rocking or oscillating pieco K.
and Figure 16. is a top view of the hinged or jointed end of the lever A¹ showing
the hole f. for the joint or fulcrum pin and the slot g. the sides of which working
against a pin on the cutter plate C₁ actuates the same as desired.
Having now described the nature of our invention we wish it understood we do
not purpose confining ourselves to the details herein described and exhibited as the
same may be varied without departing from the principle of the same but what we
claim is
The construction of appliances for trimming wicks of lamps and other purposes
substantially as herein described and exhibited.
