Balance Protector
No matter how careful a person may be, accidents will happen, and the least accident to a compensation balance gives the workman considerable trouble. The Arrick patent balance protector, Fig. 16, is intended for guarding balances from contact with turning tools, polishers and the hand rest, while work is being done upon the pivots. The staff is passed through the hole in the protector, and held in a wire chuck, and the protector is secured to the arms of the balance by two screws. The Bullock protector, shown in Fig. 17, is designed to protect the balance and other wheels from heat while drawing the temper from staff or pinion for the purpose of pivoting.
