DESCRIPTION OF A RAYOVAC
WORKHORSE FLASHLIGHT
The Rayovac Workhorse is a hand-sized plastic flashlight, easily portable, which will fit into most
automobile glove compartments. (See Figure 1.) The Workhorse's overall length is 6 inches, with a
diameter of 2 inches at the head of the flashlight, tapering to 1-1/4 inches in diameter at the battery
compartment. The body of the Workhorse, basically cylindrical in shape, is of matte black, high-impact
plastic, ribbed for a secure handgrip. The Workhorse flashlight consists of two major parts: (a) the body,
containing the battery compartment and the switch, and (b) the bulb assembly, containing the reflector,
the bulb, and the connector. The flashlight is powered by two 1.5 volt size C batteries.

BODY
The body of the Rayovac Workhorse Flashlight is 5-5/8 inches, with a diameter of 2 inches at the screw,
or head end, tapering to 1-1/4 inches at the battery compartment. The interior of the screw end is
threaded, allowing for connection with the bulb assembly. (See Figure 2 for an illustration of the complete
flashlight assembly.)
Battery compartment. The battery compartment holds the batteries, the power source for the flashlight.
The compartment is cylindrical, 3-1/2 inches long and 1-1/4 inches in diameter, with a coiled metal spring
on the interior of the closed end, and a 1/4-inch wide strip of gold-colored metal running along one
interior side of the compartment. The compartment holds two 1.5-volt C batteries, in a stacked position,
with the negative end of the lowermost battery in contact with the spring and the positive end of the
lowermost battery supporting the negative end of the uppermost battery. The open end of the battery
compartment closes with the insertion of the bulb assembly.
Switch. The switch turns the flashlight on and off. The flashlight switch is located on the body of the
Workhorse 1-1/2 inches from the screw end. The switch is of round white plastic, designed to
be
activated with the thumb of the hand holding the flashlight. When the switch is pushed forward,
towards the larger end of the flashlight, the light turns on. When the switch is returned to the
original position, the light turns off.

The Rayovac Workhorse Flashlight is a hand-sized, portable illumination device designed for general outdoor and emergency use. Its compact size allows it to fit into most automobile glove compartments.

Function Description

The primary function of the Rayovac Workhorse Flashlight is to provide light. It achieves this by converting electrical energy from batteries into light through a bulb, which is then magnified and projected by a reflector. The flashlight is activated and deactivated via a sliding switch.

Maintenance Features

The design of the Rayovac Workhorse Flashlight incorporates features that allow for straightforward maintenance, primarily concerning battery and bulb replacement.

• Battery Access: The battery compartment is accessed by unscrewing the bulb assembly from the head end of the body. Batteries are inserted in a stacked position, with specific orientation for electrical contact (negative end of the lowermost battery contacting the spring, positive end of the lowermost battery supporting the negative end of the uppermost battery).
• Bulb Replacement: The bulb is part of the bulb assembly, which screws into the body. The bulb itself is permanently fused to its metal base but can be replaced by disassembling the bulb assembly (unscrewing the reflector from the connector to access the bulb). The design ensures that both batteries and the bulb are readily accessible for replacement when needed.
