248 GOODYEAR ON GUM-ELASTIC. 



DAGUERREOTYPE FRAMES AND BOXES. 



Are manufactured of caoutchouc ivory and whalebone. The 

 frames are much Hghter, stronger, and more durable than those 

 made of wood. The tops, and also the bottoms of these boxes 

 are made of one entire piece, in moulds ; they are stronger and 

 more durable than those made of wood, covered with leather. 



FANCY BOXES. 



Fancy boxes of all kinds, together with many small articles 

 appertaining to them, are made of the hard caoutchouc com- 

 pounds. Among these may be enumerated, dressing-boxes, work- 

 boxes, snuff and tobacco boxes, &c. They are made plain and 

 polished, or with little expense are beautifully inlaid and em- 

 bossed. 



LOOKING-GLASS AND PICTURE FRAMES. 



The same general remarks that have been made as regards 

 the qualities of daguerreotype frames may be applied to looking- 

 glass and picture frames. Another desirable quality of these 

 frames is their lightness, as they can be made very thin owing 

 to the great strength of the materials, and being manufactured 

 in moulds, in one entire piece. 



IMPROVED PICTURE FRAMES.* 



This article is made of caoutchouc whalebone. It is manu- 

 factured in the same way as other caoutchouc whalebone picture 

 frames, with the addition of a revolving roll at the bottom, such as 

 is sometimes used for rolling up coach curtains. This roll, which 

 is self-acting by means of a spiral spring coiled within it, operates 

 to roll up any fabric that is attached to it. It is placed behind 

 the frame at the bottom, and the scroll upon it is drawn out by 

 a tassel. It is proposed to make these scrolls of gum-elastic tis- 

 sue or drapery, on which a catalogue or any description of the 

 subject may be printed. See plate xxii., fig.
