position as the gate g is opened either clockwise or counter clockwise the guide 72 and hence the lower end 68 follows the contour of the cam surface 42 and the hinge body 64 rotates and rises relative to the hinge body 34 as the gate is closed this is reversed the compression spring 18 provides a downward pull on the hinge body 64 via the head 22 of the hinge pin 12 bearing on the hinge body 64 to provide a closing force the guide 70 also functions to enable the gate g to resist the force of the compression spring 18 and remain in a fully open position the hinge body 64 the guide 70 cooperates with a notch 74 defined across an upper portion of the cam surface 42 so as to reside in the notch 74 this enables the gate g to resist the force of the compression spring 18 and remain in a fully open position to close the gate g the user supplies a closing force that unseats the guide 70 from the notch 74 to enable adjustment of the closing force supplied by the compression spring 12 the vertical position of the head 22 of the hinge pin 12 is adjusted by use of a set screw 80 threadably received by a threaded bore 82 of the hinge body 64 at a location proximate the head 22 of the hinge pin 12 with reference to fig3 and 5 the hinge 10 is shown with the compression spring 18 set to a minimum closing force as will.
