Thus, the motor will com- 55 mence operating to shave the ice and such shaved ice will discharge through the nozzle l5 into the glass. When sufilcient ice has been discharged into the glass, lateral movement of the glass to the left will simultaneously position the gate 2| to close the nozzle and enable the spring means to open the motor control switch and stop the motor.

It is obvious from the foregoing that by the present invention I have provided a very simple control mechanism for ice shaving machines which enables an operator to rapidly and eiiiciently ll the containers with shaved ice and further that the mechanism is so arranged that the motor is only in operation when shaved ice is desired and that the discharge nozzle is only open when there is a container positioned to receive the ice therefrom.

While I have shown the preferred form of my invention, itis to be understood that various changes may be made in its construction by those skilled in the art without departing from the spirit of the invention as dened in the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. An ice shaving machine of the character described comprising an ice shaving mechanism, an electric motor for operating said mechanism, a nozzle through which ice is discharged by operation of said mechanism, an operative gate vcontrolling the nozzle, a switch for controlling the motor, a switch operating mechanism for operating the switch, projecting means on said gate adapted to be engaged by a container whereby the gate may be operated by the positioning and removal of the container from alignment with the nozzle said gate having a projecting portion, said switch operating mechanism lying in the path of movement of said projecting portion on the gate whereby opening of the gate will be accompanied by closing of the switch.

2. In an ice shaving machine of the character described, an ice shaving mechanism, a nozzle through which shaved ice is discharged by operation of the said mechanism, a guide means extending laterally of the nozzle at the discharged end thereof, a closure for said nozzle slidably mounted on said guide for movement into and out of register with said nozzle, projections pro- Jecting outwardly from said closure and between which the edge of a container may be interposed whereby the closure may be actuated by movement of the container laterally of the nozzle.

3. The combination with an ice shaving machine comprising a container having a spout for the discharge of shaved ice, a slidable closure member for said spout, a pair of lugs extending outwardly from said closure member to receive the edge of a receptacle whereby the closure may be opened and closed by engaging said receptacle with said lugs and moving the receptacle laterally of the spout, means for shaving ice, an electric motor for operating said means, and a normally open switch mechanism adapted to be closed by opening of said closure member to place said electric motor into operation by opening of the closure member, means on said closure member contacting said switch mechanism when said closure is in open position.

4. An ice shaving machine of the character described comprising an ice shaving mechanism, an electric motor for operating the same, a nozzle through which shaved ice is discharged by the operation of said mechanism, an operative closure for said nozzle, an operative control mechanism for said motor, and means on said closure and control mechanism enabling the same to be operated together by a container when the latter is positioned to receive ice from the nozzle.

5. An ice shaving machine of the character described comprising an ice shaving mehanism, an electric motor for operating the same, a nozzle through which shaved ice is discharged by the operation of said mechanism, an operative closure controlling the discharge of ice through said nozzle, an operative switch operating mechanism for controlling the motor, said closure and said switch operating mechanism being provided with elements positioned to engage whereby movement of the closure to open position will be accompanied by operation of the switch operating mechanism to place the motor in operation.

6. An ice shaving machine of the character described comprising an ice shaving mechanism, an electric motor for operating said mechanism, a control switch for said motor, a nozzle through which shaved ice is discharged by operation of said mechanism, a normally closed gate controlling the nozzle, a switch operating mechanism for operating the motor switch and normally tending to maintain said switch open, said gate and switch operating mechanism being provided with means adapted to engage as the gate is being moved to open position whereby opening of the gate will be accompanied by operation of said switch operating mechanism to close the switch.
