Abstract: A trap loader safety assembly includes a trap target throwing machine positioned in a suitable pit having a predetermined safe position for a person loading the machine with targets. Normally the loader displays a red flag to the shooters before leaving the pit, but often this precaution is forgotten and the loader leaves the pit with no warning to the shooters. To overcome this possible danger, a seat which is normally provided for the loader, is responsive to the weight of the loader to place the throwing machine in operation and to discontinue a signal to the shooter or shooters to withhold shooting. When the loaders weight is removed from the seat the throwing machine is rendered inoperative and the signal is displayed to the shooter to withhold shooting.
