ABSTRACT:
A pay telephone station having a lower housing coin chute (14) which is provided with a coin fraud prevention unit (10) in the form of a thin base (15) arranged in a slot (11) of a coin channel cover plate (12). The base (15) is provided with a pawl (23) having a tooth (24) with a chamfered face ( b 25) which is biased into the path of a coin passing through a coin path (39) by a torsion spring (26). An anchor (59) for connecting a handset (56) to the upper housing coin dial unit (50) of the station includes a base with apertures (63, 64) and a V-shaped body (65) with a notch 66 defined between surfaces (69, 70). A long thumbscrew member (74) with a textured gripping surface connects the anchor (59) to a projector (51) integral with the upper housing (50). The handset cord assembly (A) is first passed through an aperture (54) in the projection (51) and then through the aperture (64) in the base (60). A button (68) firmly attached to a lanyard (67) in the armor (55) of the assembly (A) is held against the surfaces (68, 70) by the lanyard (67) and in the notch (66) by the thumbscrew (74) adjacent the button (68). A shorting connector (80) is provided for rapidly changing hook switch configurations in the upper housing coin dial unit (50). A configuration module (90) is used to rapidly and easily connect various circuits (93, 94, 95, 96, 97, 98, 99) on a printed circuit board (92) in the upper housing coin dial unit (50).
