<strong>Houses</strong> <strong>of</strong> <strong>Lackham</strong> 2 nd ed 70<br />
One <strong>of</strong> the best hinges for gates and external heavy doors, to<br />
coach-houses, stables, etc., is Collinge's spherical gate hinge,<br />
shown at H in Fig. 178, made on the cup-and-ball principle, the<br />
cup being on the post or pier and the ball-shaped pin on the<br />
gate strap. It will be noticed that the pin has a projecting lip,<br />
fitted with a leather washer to exclude water and dirt from<br />
the cup, which is filled with oil. <strong>The</strong>se hinges are extremely<br />
durable and easy in their working. 84<br />
<strong>The</strong> genius <strong>of</strong> these hinges was that Collinge used a socket and ball<br />
arrangement, in effect the pin <strong>of</strong> the normal hinge was made<br />
Into a sphere over which a spherical cap fixed to the other<br />
limb <strong>of</strong> the hinge is made to fit accurately; this is provided<br />
with a cavity for the reception <strong>of</strong> oil, having a small<br />
perforation to conduct it between the tow spherical<br />
surface, which work with great truth and freedom 85<br />
This spherical cap is not usually very visible, but when the doors where<br />
repaired their construction could be clearly seen<br />
