    Mosely's Impts. in the Manufacture of Artificial Masticating Apparatus. Great Britain and Ireland, the Channel Islands, and Isle of Man, an Invention for “ Improvements in tee Manufacture op Artificial Masti¬ cating Apparatus,” upon the condition (amongst others) that I, the said Ephraim Mosely, by an instrument in writing under my hand 5 and seal, should particularly describe and ascertain the nature of the said Invention, and in what manner the same was to be performed, and cause the same to be filed in the Great Seal Patent Office within six calendar months next and immediately after the date of the said Letters Patent. 10 NOW KNOW YE, that I, the said Ephraim Mosely, do hereby declare the nature of my said Invention, and in what manner the same is to be performed, to be particularly described and ascer¬ tained in and by the following statement, reference being had to the Drawings hereunto annexed, and to the letters and figures 15 marked thereon (that is to say) : The object of this Invention is to provide the mouth with an artificial masticating apparatus, which, by yielding slightly to the pressure of the jaws, will avoid the unpleasant jar in the mouth which is experienced by persons using the ordinary construction of arti- 20 ficial masticating apparatus. In carrying out my Invention, I affix to that surface of the ordinary gold plate or frame which has here¬ tofore been brought into contact with the gum a layer of wire gauge, for the purpose of receiving a coating of india rubber, which is to form an elastic cushion, and yield sufficiently to the pressure 25 of the gums to prevent the occurrence of the unpleasant jarring sensation above alluded to. In the accompanying Drawing, Fig. 1, shews in plan view, and Fig. 2, in cross section (taken in the line 1, 2, of Fig. 1), a gold plate, carrying teeth on its under surface, and provided with a yielding substance to receive 30 the pressure of the gum of the upper jaw. a, <7, is the ordinary gold plate moulded to suit the mouth of the patient, and carrying arti¬ ficial teeth h, which are rivetted or soldered thereto in the usual way. To the upper surface of the gold plate a layer of platinum wire gauze c (in part exhibited at Fig. 1), is attached. This wire 35 gauze is used for the purpose of presenting a good holding surface
