it will now be seen that when the larger diameter of the cam wheel o forces the leverla „ art k> the band v will be guided on to the smaller part of the conical drum t and theth g u r h ar t of s, consequently the drum s will at this time receive its slowest motion, ande band g will turn the blocks slower also; the reverse end of the lever l having, by theme movement, slidden the carriage into that position which causes the slivers to windthe larger diameter of the blocks.

y hen the smaller diameter of the cam is acting against the side of the lever, the«?hted cord draws the end of the lever to the opposite side, and the band v will beth !< \ oa t0 t ' le ' ar S er Part of the cord t, and the smaller part of the cone s; consequently,e quicker movement of the band g will now cause the blocks e e to revolve with a cor-an P otlt ^ n n speed.

It may bee ! e observed, that the cam wheel o should be differently formed according to the differ-ed blocks employed, so as to produce the requisite movements of the lever and

Mr. Carey, of Basford, ob-tained a patent in October, 1834,for an invention of certain ma-chinery to be employed in themanufacture of hats, which isingenious, and seems to be worthyof notice in this place. It con-sists in the adaptation of a sys-tem of rollers, forming a machine,by means of which the operationof roughing or plaiting of hatsmay be performed; that is, thebeaver or other fur may be madeto attach itself, and work intothe felt or hat body, without thenecessity of the ordinary manual
