Stapling.-The staples for securing the parts of cardboard boxes &c. are clinched by dogs pivoted in a movable anvil so arranged that the boxes can be passed continuously over the anvil without the necessity of withdrawing them back over the anvil after stapling. Box parts k, k<1>, Fig. 1, are passed over guide surfaces j<1>, j shown in section in Fig. 2, under a spring i and beneath a staple former F and driver G carried in a fixed frame E. A staple L is driven through the box parts k, k<1> against clinching-dogs C, C pivoted to an anvil B, which carries the aforementioned guides j, j' and itself is supported by a sliding spring-pressed rod h<1> and part I working in and over the frame E respectively. The anvil B carries a spring D which holds the dogs C in the position shown and protects another part k<2> of the work resting on a fixed table A. The anvil is driven down on to the table A so that the dogs C are forced upwards to clinch the staple. The anvil is forced downwards by a pin g<1> attached to the driver G engaging a similar pin f<1> attached to the forcer F and pressing on the sliding rod h<1> carrying the anvil support I.
