FRAMES, SELF-SPACING. 



METAL-SPACED HOFFAIAN FRAMES. 



All that has been said in favor of tlie reg- 

 ular Hoffman will apply with equal force to 

 the metal-spaced frame here shown. In 

 some localities wliere propolis is very abun- 

 dant, sticky, and hard, the wooden projec- 

 tions of the regular Hoffman sometimes 

 split off when the frames are pried apart. 



For localities where this condition prevails 

 we recommend the metal-spaced, which 

 can be used interchangeably with the 

 regular Hoffman. The spacers on this new 

 frame are stamped out of metal and must 

 necessarily be acciirate. The form of its 

 construction in the shape of a letter U bend- 

 ing over the top-bar projection prevents the 

 latter from breaking through careless han- 

 dling. 



STAPLE-SPACED FRAMES. 



There are some others who prefer frames 

 with staples for side-spacers, as here shown. 

 (Jthers use nails in place of staples •, but the

latter with their rounding edges allow the 

 frames to slide past each other worse. 



OTHER SELF-SPACING DEVICES. 



Various spacing-devices have been sug- 

 gested at different times. A few of these 

 we present here, leaving the reader to judge 

 of their relative merits. It will not be neces- 



sary to describe them in detail, as the 

 engravings make plain their manner of con- 

 struction and use. 



It will be noted that there are two kinds 

 of spacing-devices. One is made a part of 

 the frame and the other a part of the rabbet. 

 It would seem at first glance that the latter 

 would be a very happy solution of the prob- 

 lem of automatic spacing, as it would leave 

 the frames without projections in the way 

 of uncapping; but the fact is, rabbet or hive 

 spacers have never been very popular, and 



IIIVE-RABHET SPACERS.* 



* These are nailed on the side of or in the wooden 

 liive-rabbet— the top-bars or frames resting between 

 the notches or bends of the sheet metal or wire.
