Abstract
Abstract A parking charge display device has a rotating disk carrying circumferentially spaced switches. The disk is located in front of a clock dial. Spacing of the switches corresponds to time intervals for which parking charges are to be made. Pressing any switch lights one of a row of lamps located behind prices posted on a display panel. Inside the device is a distributor drum with conductive rings wiped by brushes and connected in circuit with the switches and lamps.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
190 words
A display device for parking time charges, comprising a cabinet; a stationary panel at one side of the cabinet displaying a graduated time clock dial; a disk rotatably disposed in front of said panel and having a pointer to indicate time on said time clock dial; motor means in the cabinet; an axially horizontal shaft rotationally mounted in the cabinet operatively arranged for rotation by said motor means, said disk being carried by said shaft for rotation by said motor means; a multiplicity of manually operable switches carried by said disk near its periphery adjacent to said time clock dial in a circumferentially spaced array on the disk corresponding to timing intervals on said clock dial; a transparent plate mounted on the cabinet and bearing a row of numerical indications of parking time charges; stationary lamps located behind said plate at the respective numerical indications to illuminate the same; and circuit means electrically interconnecting said switches and lamps so that when any one switch on the disk adjacent a time indication on the clock dial is operated, one of the lamps lights up to indicate a particular parking time charge.
Claim 2
Dependent Claim
190 words
A display device for parking time charges, comprising a cabinet; a stationary panel at one side of the cabinet displaying a graduated time clock dial; a disk rotatably disposed in front of said panel and having a pointer to indicate time on said time clock dial; motor means in the cabinet; an axially horizontal shaft rotationally mounted in the cabinet operatively arranged for rotation by said motor means, said disk being carried by said shaft for rotation by said motor means; a multiplicity of manually operable switches carried by said disk near its periphery adjacent to said time clock dial in a circumferentially spaced array on the disk corresponding to timing intervals on said clock dial; a transparent plate mounted on the cabinet and bearing a row of numerical indications of parking time charges; stationary lamps located behind said plate at the respective numerical indications to illuminate the same; and circuit means electrically interconnecting said switches and lamps so that when any one switch on the disk adjacent a time indication on the clock dial is operated, one of the lamps lights up to indicate a particular parking time charge.
Claim 3
Dependent Claim
101 words
A display device as defined by claim 1, further comprising an insulative drum carried by said shaft, said rum having a multiplicity of conductive rings axially spaced apart thereon; a first electrical connector carried by said drum and rotating with the drum on said shaft, said connector having contacts connected to said rings respectively; a second electrical connector attached to said disk and having elements engaging said contacts respectively, said switches being connected to said elements, and said rings being connected to the lamps, whereby electric current flows through a particular ring, switch and lamp when the last-named switch is operated.
Claim 4
Dependent Claim
41 words
A display device as defined by claim 2, further comprising a support carrying a plurality of brushes respectively disposed to wipe the rings when the drum rotates, said brushes being connected in circuit with the lamps to conduct electric current therethrough.
Claim 5
Dependent Claim
62 words
A display device as defined by claim 3, further comprising an electrical power supply; a conductive annular member carried by said panel disposed to be contacted by each switch when closed, said power supply being connected to said annular member and to said lamps, whereby a selected lamp is energized and lights up when a selected switch in circuit therewith is operated.
Claim 6
Dependent Claim
44 words
A display device as defined by claim 1, further comprising means removably mounting said disk on said shaft so that the disk can be removed and replaced by another having other switches thereon spaced to correspond with other timing intervals on said clock dial.
Claim 7
Dependent Claim
40 words
A display device as defined by claim 1, further comprising means removably mounting said plate at the front of the cabinet for displaying said parking time charges thereat, and for replacing the plate with another to display other time charges.
Claim 8
Dependent Claim
57 words
A display device as defined by claim 1, further comprising a stamping means on said cabinet for stamping on the time indicated by said pointer at said dial; and link means operatively interconnecting said motor means and said stamping means to synchronize change of time stamped by the stamping means with the time indications of said pointer.
Claim 9
Dependent Claim
63 words
A display device as defined by claim 2, wherein the drum is hollow and wherein the first connector is a socket mounted in one end of the drum and having contact lugs open to the interior of the drum, said rings having other lugs also open to the interior of the drum and connected by wires respectively to the lugs of said socket.
Claim 10
Dependent Claim
37 words
A display device as defined by claim 8, wherein the second connector is a plug having prongs detachably engageable with the contacts of the first connector, whereby the disk is removable with said plug from said shaft.
