Abstract
Abstract A protective anti-vandalism device for a pay telephone. The device consists of an outer impact-resistant support member containing an annular raceway member having a reduced end portion engagable in the dial aperture of the telephone. A substitute disc-like dial is rotatably mounted in the raceway member by means of ball bearings between the periphery of the substitute dial and the raceway. The substitute dial has outwardly facing recesses circularly arranged and numbered to correspond with the dial numbers of the telephone and being registrable therewith when the support member is secured to the telephone around its dial aperture. A drive member is secured to the inside surface of the substitute dial in axial alignment with the zero recess and is engagable in the zero opening of the telephone dial rotary member. The annular support member has an inwardly projecting finger stop plug registrable with the finger stop plug of the telephone dial assembly when the support member is secured to the telephone around the dial aperture. Said support member is secured to the telephone by means of fastening screws passed through the wall of the telephone housing from the inside.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
203 words
A protective device for the rotary dial assembly of a pay telephone of the type having a generally circular dial aperture provided with an inwardly projecting finger stop lug and a rotary dial having number holes at the same radial distance as said finger stop lug, the rotary dial being exposed through the circular aperture, said protective device comprising a generally annular support member shaped to engage on a pay telephone around the dial aperture substantially in concentric relation therewith, a substantially disc-like substitute dial rotatably and coaxially mounted in said annular support member, said substitute dial having circularly arranged recesses in its front face located to register with the number holes, a rearwardly projecting drive element, means supportingly connecting said drive element to the rear surface of said substitute dial at one of said recesses so that said rearwardly projecting drive element is drivingly engagable in a number hole when the support member is engaged on the telephone around the rotary dial aperture, finger stop means on the support member located to register with the finger stop lug of the rotary dial assembly, and means to secure the support member to the telephone in said substantially concentric relation with the dial aperture.
Claim 2
Dependent Claim
203 words
