In rivetingby hand the workman finds it necessary to bring the plates upon which he is opera-ting into close contact, by striking them with his hammer while closing and finishing the head of therivet. The necessity of this will be obvious when we consider that the iron pin, which is to form therivet, tends, by the compression to which it is subjected by the blows of the hammer, to stave up through-out its whole length, as well as at the end, and that, consequently, unless the plates are

The necessity of this will be obvious when we consider that the iron pin, which is to form therivet, tends, by the compression to which it is subjected by the blows of the hammer, to stave up through-out its whole length, as well as at the end, and that, consequently, unless the plates are brought intovery close contact during the operation, an obstacle to their perfect junction is interposed by the verymeans employed to bring them into intimate contact. In M. Lemaitres machine this difficulty is obvi-ated by a very ingenious and effective contrivance which we shall now proceed to describe. Fig. 3220 is an elevation. Fig. 3221 a plan. Fig. 3222 an end view, and Fig. 3223 a partial sectionof the steam punching and riveting machine. 3220. 3222-.
