the spider wheel, v", coming against the lever, S", is turned two lines. Wlien 

 ■within four letters of the end of a line, a little bell rings to give warning in time 

 for the word to be divided by a hyphen. The paper is not touched by the operator 

 till the page, which is constantly before his eyes, is finished. With a little prac- 

 tice, one can print fifty per cent faster than the ordinary writing. 



Fig. 2 is a sectional view of one key working on a hinge screwed to the crossbar 

 C, and having a counterweight, M. Pressing on the key, K or K', that part of L 

 at o" pulls the wire S, which moves the rocker p', carrj^ing with it the pawl p, the 

 hammer Z V, screwed on the circle Y, set into the frame A, strikes up against the 

 common centre, PI, which is the stud k, fig. 1. 



Fig. 3 is a front view of the top-bolts under the keys, 

 to prevent more than one going down at the same time. 

 This is necessary on account of there being but a com- 

 mon centre for all the types to strike. The stop-bolts, 

 P P' P ', work on the screws, R R' R", having their tops 

 beveled so as to fit in between the keys, K K' K", etc. 

 When a key is depressed, the stop-bolts are driven to 

 the right and left of it, and consequently under all the 

 other keys. 



The letters can be formed of any sized type, engraved for the purpose, and suit- 

 ing the taste of the purchaser. Those who use this " Writing Printer " will be 

 enabled to strike off two copies in less time than is required to produce one with 

 the pen. Divines, while in the pulpit, will be freed from the inconvenience attend- 

 ing an ordinary manuscript ; authors secured from losing the result of many hours 

 of mental application, by the destruction of a single copy while in the hands of 

 the publisher; editors no longer troubled by the necessary correction of errors in 

 proof-sheets, incident to manuscript copies; reporters may, with less labor, furnish 

 printed reports; and merchants, while writing a clearer letter and saving time, 

 may keep neatly-printed copies, instead of the illegible ones they now obtain by 

 means of the copying-press. 



The price is ^100. The position of the " writer " being ere»t, is eminently con- 

 ducive to gracefulness and health, and the whole page is directly under his eye. 

 Literary men cannot fail to take a deep interest in the success of this invention. 

 With it, a bad chirography may be concealed, but let bad spellers beware of its 

 fascination. [^ diploma awarded.

said to be about one cent a week. 



This instrument is used by the dental 

 profession in extracting teeth. It has 

 a direct current, as well as a to-and-fro 

 current, and the zincs never require 

 cleaning. The expense of running it is
