THE MONEY-BOX.

placed upon an inclined plane, and resting against the glass. The pieces of 

 money, in falling, strike the extremity of a vertical balance, which imme- 

 diately turns a toothed wheel, C. This wheel has as many teeth as there 

 are pieces of money necessary to purchase the photograph or carte de visite. 

 Upon the escapement wheel is a ratchet arrangement, D, the shaft being 

 moved by a cord rolled around it and attached to a spring, E. A bolt, F, 

 moved by a spring, is kept constantly pressed against the " snail," D. 



Thus at each revolution, as the parts of the machinery are animated 

 by the same movement, the bolt is withdrawn sufficiently to permit a carte 

 to fall, and then the card next following will be ready resting upon the bolt.

The photographs being placed upon an inclined plane, are pushed forward 

 by a movable frame, G, which has a roller at the base. So as one card falls 

 out another is immediately replaced close to the glass. 



We have remarked that the wheel has six teeth, so that as one piece of 

 money dropped in moves it one-sixth of its revolution, six pieces will be 

 necessary to produce the card Of course wheels can be made with one or 

 more teeth, and the payment may be varied for valuable objects at the desire 

 of the possessor. 



The invention is not only a plaything. It can be made useful in the 

 distribution of pamphlets, or newspapers, which can be introduced into the
