Description: |
| Abstract:
In a machine for swaging and side-dressing the teeth of band and other saws, the saw is fed intermittingly by a finger 23 carried by a lever 22 and adapted to engage the teeth of the saw, and while the saw is stationary one tooth is swaged to press the metal out laterally on both sides by a rotary tool 6 coacting with a stationary anvil 4, and a previously swaged tooth is side-dressed between a pair of laterally acting tools 48. The saw is clamped by a jaw 24 actuated by a cam on a shaft 28, and both the jaw 24 and the swaging-tools are mounted on a slide 3 which is moved upwards on inclined guides 2 and against the action of a spring 18 to move the tools out of the path of the saw teeth while the saw is being fed. The dressing- tools 48 are carried by arms 47 adapted to rock laterally on pivots 46 mounted on a block 45 pivoted to the machine frame at 44. Conical rollers 42 are carried by arms 41 projecting from a shaft 40. When this shaft is rocked, the rollers 42 rock the arms 47 first on the pivot 44 until they are arrested by a stop on one of the tools 48 engaging the saw tooth to be dressed, and then on the pivots 46 to cause the tools to operate upon the tooth. When the rollers 42 are raised, the arms 47 are pushed back by a spring 51 and are separated by a wedge 52. |
