 SAXBY & FARMER'S IMPROVED PATENT FACING POINT LOCK HAS THE FOLLOWING ADVANTAGES: 1st. — The Points must be properly set, dose home to the stock rail, or the Signal for a Train to pass cannot possibly be given, and the least obstruction occurring to prevent the full and true opening or closing of the Points is at once discovered, even with connecting rods of the greatest length practicable. 2nd. — The Points are wedged firmly and immovably in the position indicated by the Signal, and the ordinary jolting and jarring occasioned by passing Trains is avoided. . 3rd.— Whilst a Train is actually travelling through the Points, it is itself master of the situation ; not even the Signalman can, either intentionally or inadvertently, change their position or disturb them until the whole Train is safely passed.
