Abstract
The machine consists of a bearing box which is secured onto the trunk of the machine and is equipped with a pair of axes at both sides and suspends the center of gravity of the machine to rotate same freely, and a U-type supporting device is installed at the axes respectively, and a revolving or swivel joint is installed at the upper end of the above supporting device so as to enable the machine to rotate freely.
Claims1
The combination of a casting-gate breaking machine having a body portion with an outer surface, and a supporting device including:
- a ring-shaped bearing installed on said outer surface of said body portion of said casting-gate breaking machine enabling rotation thereof around a central axis of said body portion;
- a pair of pivot pins outwardly extending from said ring-shaped bearing;
- a U-shaped supporting member having a top and having opposite arms with free ends for supporting said ring-shaped bearing by means of said pivot pins engaged at said free ends of said arms;
- a horizontally rotatable coupling secured to the top of said U-shaped supporting member for freely rotating said U-shaped member;
- a shackle connected to said rotatable coupling;
- and
- a flexible line connected to said shackle at a lower end and connected to a ceiling structure at an upper end thereof;
- whereby
- said breaking machine when in use and suspended from said ceiling structure by means of said flexible line and said rotatable coupling is capable of substantially omnidirectional movement.
