BARNARD AND JOY'S PATENT SELF

ROLLING MANGLE.

The engraving on our front page is a perspective view of an improved mangle patented some time ago by Messrs. Barnard and Joy, of Norwich, in which weighted rollers have been substituted successfully for the cumbrous travelling bed now in use. It is very compact, occupying not more than one-fourth the space of the ordinary clumsy machine; it has already been extensively used, and, we are informed, with equal, if not superior, efficacy to both the common, and Baker's patent, mangle.

In the view on our front page NNN is the framework of the machine; A, B and C are three rollers or cylinders; E is a cross rail at the bottom of the machine, from which is suspended the weight F. K K are vertical grooves or slots in the upright posts of the framework N, in which the ends of the axis of the roller A are free to move up and down; M M are two other vertical slots in the upright posts, in which the ends of the cross rail E are also free to move up and down; DD are bars inFig. 2

the upright posts N N. for the purpose of connecting the roller A with the cross rail E, and the weight F attached thereto. The form of one of these bars is shewn more clearly at fig. 2; d being the hole through which the axis of the roller or cylinder A passes; XX a slot to allow of the free action of the axes of the rollers or cylinders B and C, and e, the hole for receiving the end of the cross rail E. LL are slots in the upright posts of the framework, in which the ends of the axis of the middle roller B are free to move, but which slots form a segment of a circle described from the centre of the pinion H, instead of being vertical. The vertical slot K, and the curved slot L, are more clearly shewn in figure 3, which exhibits a portion of one of the posts N with the slots therein; the wheel G being removed. G is a wheel fixed to one end of the axis of the middle wheel B (outside of the framework NNN), and H, & pinion, which works into the teeth of the wheel G. C, which is the lowest of lowest of the three rollers is required to revolve at one fixed point of elevation only, and has therefore no such range of action provided for as in the cases of the rollers A and B. O is the table which carries the articles to be mangled or calendered;, P, brackets supporting the table O, and projecting from the framework N. Fig. 4, is a section of the Fig. 4.
