Description: |
| Heath Sutherland - patent attorney
This invention relates to a machine which is similar in many respects to that set forth in my contemporaneously pending application filed April 5, 1917, Serial No. 159,883 (patent # 1,323,276. The present machine like that in said other application can be utilized in widely different arts, although it is of especial advantage in the production of bullets such for instance as are used in small arms. The present machine, like that in the aforesaid application, comprises mechanism for supporting a blank and for supplying to the blank one or. a succession of blows upon its surface. In the earlier application before referred to, I have shown a machine having two rotatable rollers for applying a plurality of blows in rapid succession to the surface of the blank, these blows being delivered by means of ribs formed on the surface of two rapidly rotating rollers arranged side by side. In the present case I make use of an outer annular roller and an inner roller which is surrounded by the outer roller and which is arranged eccentrically with respect thereto. The bullet blank is engaged and acted upon by the surfaces of the two rollers at the throat where the surfaces are close together. |
