THE NEW PATENTS LATELY ENROLLED. 



VK. EicHARD Wilcox's (LAMBETn), /or 

 certain Machinery for glazing and 

 graining Leather. 



THIS invention is performed by fo 

 difpoling a number «r fciies of linall 

 rollers fomiinp; a circle round a large 

 roller, which are placed in fuch a man- 

 ner that one, two, or three of the faid 

 rollers iliall be on the ikin at one time, 

 by which means a preffure is eii'cftcd 

 ■without bieakinii or injurino; the Ikin. 

 The rollers are fo arranged, that at every 

 rotation of the large roller tlic Imali ones 

 commence their operations oa the mid- 

 dle part of the ikin, and work from the 

 centre outward. When fix rollers are 

 iifed, three of them turn to the right 

 and the others to the left. In order to 

 jiroduce the grain, the fkin is full placed 

 in a fcafoncd or damp flatc between the 

 rollers, and after gla/ing the ikin w ithout 

 any grain, it is placed in contatt Avitli a 

 copper plate prcvioully engraved fo as to 

 produce an imjnelfion Imiilar to that 

 wrought on tlie IkJn by hand, and then 

 the fkin and plate are paflcd between 

 the rollers of a profs. ElalHc varniih is 

 ufed to finirti the fkin, by whicli means 

 a moll beautiful iniprcHion nnd polilh is 

 given to it. 



The moll convenient fize for the large 

 roller is about four feet fix inches long, 

 and one foot iii diameter, which is to be 

 divided longitudinally into iifvy equal 

 'parts or divihons ; the circumference is 

 alfo divided into fifty parts. Wh.cn the 

 Imall roller is placed for grnining and 

 glazing the leather, whicli is about two 

 inches -and a half diameter, fixed into a 

 fpring about ten inches long, and equal 

 to carry two hundred weight, bent fo as- 

 to form a circle about fourteen inches 

 diameter ; wb.ich fpnng and glazing rol- 

 lers are placed on tho won roller, dlvitled 

 as above delciibed. The firlt fpring is 

 fixed OH the centre divifion marked on 

 the irqn roller, the fccond rp'Jng is fixed 



on the third line, and the third fpring 

 on the fifth, and fo on, drawn longitu- 

 diually on the iron roller; but, on the 

 contrary, each roller is to be ilxed to 

 every line iucceffively drawn round the 

 circun;fcrence on the iron roller. Hence 

 whan the firll let of rollers is fixed to 

 the iron roller, it will co\er it longitu- 

 dinaly, and but half w-ay in circumfeiv 

 ence. The fccond feries of rollers i« 

 placed beginning on the fccond longi- 

 tudinal line, mixed by the firft feries of 

 rollers, and fo on fucccflively ; but in a 

 dircri line where the firll feries of rollers 

 terminated ; fo that as foon as the firll 

 feries Ihall have palled the ikin, the fe- 

 cond feries fliall then commence : thus, 

 as the rollers are nearly tu ice the width 

 of the fpaccs marked mi the iron roller, 

 and crofs each other's track, tliej lap or 

 cover each other during every revolution 

 about three quarters of an inch, by 

 which means the whole fkin is comjilcte- 

 ly grained and glazed. In order to ad- 

 jull the faid finall rollers into a regular 

 line, fo that they may piefs on the bed, 

 an adjulting fcrew is placed tapped into 

 the fprings holding the finall glazing rol- 

 lers; and as the end of the adjufting 

 fcrew comes in contact with the iion cy- 

 linder, the faid fprings and rollers aro 

 readily and fpeedily adjulled. The rol- 

 lers are grooved or fluted, and the ikin 

 prepared and worked by the machine in 

 a limilar manner to thofe fkiiis worked 

 by the hand ; and the rollers are turned, 

 and the Ikin moved forvv;ud aud turned 

 by any of the fimple methods of nui- 

 chincry. The patentee does not con- 

 fine his fpecification to any particular 

 proportions ; his great object is to pro- 

 duce the following efi'efts : firft, tlsat not 

 more than two or three graining and 

 glazing rollers be on the Ikin :it or.e 

 Uine; fecondly, that they tend to fmootli 

 the fkin; thirdly, that the fecond tier or 

 Icrics of rollers co\ cr tlic fpacts left iiy
