Abstract
Abstract A drink vending machine has a cabinet in which two liquor containers are supported. A rubber hose connects each container to an optic type measure and to the bottom of a sight glass which extends upwardly from the optic type measure. Two platforms are mounted on a common lever below the measures respectively, and the lever is tipped by the weight of a drinking glass placed on one of the platforms, thereby closing a circuit which causes a drink to be discharged from the selected measure if coins are simultaneously deposited in a coin-feeding apparatus. A float in each sight glass may cause the coin slot to be blocked and an ''''empty'''' sign to light up when the float interrups the passage of light between a light source and a photoelectric cell.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
150 words
A vending machine for dispensing a liquid comprising: a. a cabinet adapted to support a container for said liquid; b. an optic type measure mounted on said support; c. a sight glass fitted to and extending upwardly from said measure; d. a tube connected to the lower end of said sight glass above said optic type measure and having a free end adapted to be connected to a container for said liquid supported by said cabinet; e. supporting means for supporting a drinking glass in a position in which a measure of liquid may be supplied to said drinking glass from said optic type measure; f. actuating means for actuating said optic type measure to dispense a measured quantity of said liquid to said drinking glass; and g. operating means responsive to the weight of a drinking glass supported by said supporting means for bringing said actuating means into operation.
Claim 2
Dependent Claim
150 words
A vending machine for dispensing a liquid comprising: a. a cabinet adapted to support a container for said liquid; b. an optic type measure mounted on said support; c. a sight glass fitted to and extending upwardly from said measure; d. a tube connected to the lower end of said sight glass above said optic type measure and having a free end adapted to be connected to a container for said liquid supported by said cabinet; e. supporting means for supporting a drinking glass in a position in which a measure of liquid may be supplied to said drinking glass from said optic type measure; f. actuating means for actuating said optic type measure to dispense a measured quantity of said liquid to said drinking glass; and g. operating means responsive to the weight of a drinking glass supported by said supporting means for bringing said actuating means into operation.
Claim 3
Dependent Claim
59 words
A machine as set forth in claim 1, wherein said actuating means are operated by an electric circuit, said supporting means include a support member mounted for displacement under the weight of said drinking glass, and said operating means include switch means closing the operating circuit of said actuating means in response to said displacement of said support member.
Claim 4
Dependent Claim
60 words
A machine as set forth in claim 2, wherein said actuating means include an electric motor in said operating circuit, a cam connected to said motor for being rotated thereby, and motion transmitting means operatively interposed between said cam and said optic type measure for actuating the latter to dispense a measure of said liquid when said motor is energized.
Claim 5
Dependent Claim
28 words
A machine as set forth in claim 2, wherein said supporting means include pivot means securing said support member to said cabinet for pivotal movement under said weight.
Claim 6
Dependent Claim
36 words
A vending machine as claimed in claim 2, including a control switch that can be set so as to enable the machine to be coin-operated, or alternatively, manually operated without insertion of coins into the machine.
Claim 7
Dependent Claim
73 words
A machine as set forth in claim 1, further comprising a float in said sight glass; a source of light and a photoelectric cell on respective opposite sides of said sight glass adjacent said lower end of the same; and indicator means on said cabinet operatively connected to said cell for providing visible indicia when passage of light from said source to said cell through said sight glass is interrupted by said float.
Claim 8
Dependent Claim
65 words
A machine as set forth in claim 6, further comprising coin-operated mechanism for preventing the bringing into operation of said actuating means by said operating means unless a coin is inserted in said mechanism, said cabinet being formed with a coin entry opening, and said mechanism including means for blocking said entry opening in response to interruption of said passage of light by said float.
