(3.) The lift, or raiser (Figs. 1 and 87c), serves to raise the roof 
sufficiently to permit of crates (29) of 
22. Lift of C. D. B. sections, or boxes of frames for extracting 
Hive. (81), being placed above the body-box, so 
that the bees can obtain access to them 
from the brood chamber in order to fill the sections or super 
frames with surplus stores of honey for removal. In winter 
the lift should be inverted and slipped down over the body-box 
(180). A second lift (111) can be fitted over the lower lift, when 
it is desired to place more than three crates of sections on the hive. 
(4.) The roof (Fig. 1) serves only as a protection from the 
weather; not to confine the bees. It is 
23. Roof. fitted in front with two perforated brass 
cones (42), forming a non-return bee 
escape, and at the back with a perforated zinc ventilator. 
Bar-frames are of the pattern known as the “‘ Abbott” bar- 
frame (Figs. 1,10 and 31). They vary from 
24. Bar-Frames. the dimensions of the “ Standard” frame 
as fixed by the British Bee-keepers’ Asso- 
ciation, in that the top bar is half-inch thick, instead of being 
only three-eighths inch thick, as specified for the “Standard ’” 
frame; this extra thickness of the top bar is given to prevent 
sagging: these frames can be used in any hive constructed to take. 
‘“* Standard ”’ frames, but should not be used in the same hive 
with “‘ Standard ”’ frames unless the latter are raised to the same- 
level by fixing slips of wood one-eighth inch thick under the 
shoulders of the “‘ Standard ”’ frames ; otherwise the eighth-inch 
spaces above the shoulders of the “ Standard ” frames would be 
filled with propolis by the bees when the section crates are on, 
(110). The under side of the top bar of the “ Abbott ” frame is 
fitted with two machine-cut grooves to receive foundation 
(88), (73). The frames are kept at the correct distance apart 
by the shoulders at each end of the upper bar. Bar-frames. 
should be made with the greatest accuracy as to measurement 
so that they may all be exactly of one size ; it is therefore best 
to buy machine-made frames rather than to make frames at 
home, which is almost certain to prove unsatisfactory. The 
dimensions of the “‘ Abbott” bar-frame as here described are. 
as follows :—Extreme width of top bar, 17 inches; extreme 
breadth of shoulder, 14 inches; ‘width of top bar between: 
shoulders, about $ inch; extreme width from outside to out- 
side of perpendiculars, 14 inches; depth of frame from under: 
side of top bar to under side of bottom bar, 8 inches; depth of 
top bar, 4 inch. 
The division-board, usually called the “dummy ” (Fig. 5), is. 
used for separating that portion of the 
25. Division-board body-box to which the bees have access 
or Dummy. from the portion from which they are ex- 
cluded ; it is a board the full depth of and. 
almost the full width of the body-box, strengthened by two.
