A protective cover for the coinbox-containing portion of pay telephones of generally box-like construction, comprises a front panel flanked by a pair of parallel, rearwardly-extending side walls to define a generally U-shaped construction. The construction closely abuts the front and side panels of the telephone. The front panel is adapted to be permanently fastened to the coinbox cover of the telephone, such as by welding, and has an entryway to the telephone coin return slot and an integral raised portion positioned to overlie the top portion of the coin return door plate of the telephone. |

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT Referring initially to FIG.
1, pay telephone 10 is of conventional construction, and includes telephone box 12 having front panel 14 upon which coin slot 16, coin transport clearing lever 18, push-button array 20, headset cradle 22, coinbox access door plate 24, coinbox lock 26, coin return slot 28 and coin return slot cover 30 are located.
Additional key-operated lock elements 32 and 34 are located on a side 36 of the box to allow access to the unit's interior by authorized personnel, one of which locks, such as lock 34, normally functions in conjunction with coinbox lock 26 to allow access to the coinbox.
A handset 38 rests in cradle 22, and is connected by cable 40, normally encased in a tamper-resistant shield to the third side 42 of the box.
The shield and protective plate 44 of the present invention is of generally U-shaped construction formed of heavy gauge metal, such as 0.
145 inch thick stainless steel, having a front panel 46 flanked by side walls 48 and 50.
The width of front panel portion 46 is such that side walls 48 and 50 closely embrace the sides 36 and 42 of the telephone box 12.
The height of the plate is such that it fully overlies the lower portion of the telephone box 12, wherein the coinbox is located.
As may be seen, side wall 50 is provided with a notch 52 adapted to allow access to the lock 34 and to permit the plate to be slid on and off the box 12 when a key is inserted into, and projects from the lock.
An entranceway 54 is provided on the front panel 46 of the plate to allow access to coinbox lock 26.
As further depicted in FIGS.
2 and 3 and, as detailed therein, the front panel 46 of protective plate 44 is further provided with an entryway 56, as well as a generally circular, raised portion 58 which allow the coin return mechanism, exemplified by the coin return slot and cover 28, 30 and clearing lever 18 to operate in the appropriate manner.
The coin return mechanism of the telephone 10 includes a coin return slot cover 30 designed to pivot about pin 60 as shown in FIG
