Abstract

This invention provides a control injection system for adding a chemical and/or water from a metering device to a programmed drycleaning machine for a predetermined time interval. The control injection system comprises an automatic reset electrical timer having a dial which is setable for the predetermined time interval, a load terminal in communication with one or more metering devices, and receiving and relaying means for receiving a signal from the programmer of the drycleaning machine and relaying the signal to start the timer and energize the load terminal to actuate the metering devices to admit the chemical and/or water into the drycleaning machine for the time interval set on the timer. The timer being arranged to de-energize the load terminal at the end of the time interval independent of the length of the signal from the programmer.

Claims

1. An automatic control injection system for adding a chemical and/or water from a metering device to a programmed drycleaning machine for a predetermined time interval, said injection system comprises an electrical circuit which includes an automatic reset timer settable for the predetermined time interval, a load contact adapted to be connected to said metering device, and receiving and relaying means for receiving a signal from the programmer of the drycleaning machine and relaying the signal to start the timer and energize the load contact to actuate the metering device to emit the chemical and/or water into the drycleaning machine for the time interval set on the automatic reset timer.

2. An automatic control injection system according to claim 1, wherein the automatic reset timer is arranged in said circuit to de-energize the load terminal at the end of the predetermined time interval independent of the signal time length received from the programmer of said drycleaning machine.

3. An automatic control injection system according to claim 1, wherein the length of the signal received from the drycleaning programmer is shOrter than the time interval set on the timer.

4. A control injection system according to claim 1, wherein the length of the signal received from the drycleaning programmer is longer than the time interval set on the timer.
