Abstract
Abstract A coin receiving prepay telephone station for local calls includes a telephone receiver and transmitter with a handset and a supporting hook switch cradle therefor. The station further includes a coin chute having an open end for receiving a coin and a lower end for discharging coins into a coin box. A solenoid controlled arm is movable transversely into and out of the coin chute adjacent a level near the open end for normally retaining a coin deposited in the chute in a partially exposed retrievable position permitting manual extraction from the chute if a call dialed from the station is not answered. Circuitry is provided for activating the solenoid controlled arm to move out of the coin chute permitting the coin previously retained therein to drop into the coin box when a called party answers a call of over three digits dialed at the station.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
125 words
A coin receiving telephone station for local calls only includes a telephone receiver and transmitter with a handset and a supporting hook switch cradle therefor comprising: a coin chute having an open end for receiving a coin and a lower end for discharging coins into a coin box; solenoid controlled arm means movable into said coin chute adjacent said open end for retaining a coin deposited in said chute in a partially exposed retrievable position permitting manual retraction from said chute; and circuit means for activating said solenoid controlled arm means to move out of said coin chute for permitting a coin previously retained therein to drop into said coin box when a called party answers a call over three digits dialed at said station.
Claim 2
Dependent Claim
125 words
A coin receiving telephone station for local calls only includes a telephone receiver and transmitter with a handset and a supporting hook switch cradle therefor comprising: a coin chute having an open end for receiving a coin and a lower end for discharging coins into a coin box; solenoid controlled arm means movable into said coin chute adjacent said open end for retaining a coin deposited in said chute in a partially exposed retrievable position permitting manual retraction from said chute; and circuit means for activating said solenoid controlled arm means to move out of said coin chute for permitting a coin previously retained therein to drop into said coin box when a called party answers a call over three digits dialed at said station.
Claim 3
Dependent Claim
134 words
The coin receiving telephone station of claim 1, including: a housing having an outer wall and enclosing said coin box, said coin chute mounted in said housing with said lower end positioned to discharge coins moving downwardly through said chute into said coin box; said open end of said chute positioned to be in communication with the exterior of said housing for receiving coins manually placed therein; and said arm means normally projecting into said coin chute at a level to engage a lower portion of a coin inserted into the open end of said chute and support said coin at an elevation therein wherein an upper portion of said coin is exposed above said chute for manual retrieval until said arm means is retracted permitting said coin to drop into said coin box.
Claim 4
Dependent Claim
79 words
The coin receiving telephone station of claim 2, wherein; said coin chute includes an upper end portion extending outwardly of said outer wall of said housing and comprising a pair of opposite, parallel side walls and a pair of narrow opposite edge walls transverse thereto, said opposite side walls having cut away portions at the upper end of facilitating manual retrieval of a coin while retained in said retrievable position therein by said arm means projecting into said chute.
Claim 5
Dependent Claim
42 words
The coin receiving telephone station of claim 1, including; slug detector means activated by the placement of a slug in said retrievable position in said coin chute for retracting said arm means to permit said slug to drop into said coin box.
Claim 6
Dependent Claim
78 words
The coin receiving telephone station of claim 4, wherein; said slug detector means comprises a magnetic element attracted to move from a first position to a second position by the presence of a magnetic slug in said retrievable position in said coin chute, and switch means responsive to the movement of said magnetic element toward said second position for activating said arm means to retract from said coin chute permitting said slug to drop into said coin box.
Claim 7
Dependent Claim
23 words
The coin receiving telephone station of claim 5, wherein; said slug detector means includes means biasing said magnetic element toward said first position.
Claim 8
Dependent Claim
31 words
The coin receiving telephone station of claim 1, wherein; said circuit means includes circuitry permitting a called party to answer a call made from said station by dialing only three digits.
Claim 9
Dependent Claim
51 words
The coin receiving telephone station of claim 1, including; biasing means normally urging said arm means into said coin chute, and wherein said solenoid of said solenoid controlled arm means is activated to move said arm means out of said coin chute in response to the answer of a called party.
Claim 10
Dependent Claim
34 words
The coin receiving telephone station of claim 8, wherein; said solenoid is deactivated to permit said arm means to return to said position extending into said coin chute when said called party hangs up.
Claim 11
Dependent Claim
44 words
The coin receiving telephone station of claim 8, wherein; said solenoid is deactivated to permit said arm means to return to said position extending into said coin chute when said handset is returned to be supported on said hook switch cradle of said station.
Claim 12
Dependent Claim
41 words
The coin receiving telephone station of claim 1, wherein; said circuit means is inoperative to activate said solenoid controlled arm means to move out of said coin chute when a call over three digits is dialed beginning with the digit "0".
Claim 13
Dependent Claim
41 words
The coin receiving telephone station of claim 1, wherein; said circuit means is inoperative to activate said solenoid controlled arm means to move out of said coin chute when a call over three digits is dialed beginning with the digit "1".
