Presented is a coupling device designed to release two members that are connected together when more than a predetermined force is exerted to separate the two members. The coupling device is adjustable to increase or decrease the amount of force to which it responds. Structurally, the device includes a plug member having a spherical knob seated in a complementary seat formed in a surrounding tube having longitudinal slits. A sleeve surrounding the tube is slidable between maximum and minimum force settings to control the amount of force required to separate a member connected to the plug member from another member connected to the tube.

A gas heated direct fired center tube revolving ironer for use in an automated fabric ironing environment features improved roller surface temperature distribution control. An adjustable hot air recirculation system with a venturi throat, a high momentum gas burner, an improved temperature control system and an exhaust blower cooperate to provide an even temperature along the ironing surface. Multiple high and low temperature controls provide backup and ensure accuracy and safety. The gas fuel consumption is minimized thereby reducing operating costs.

High momentum heating system for an ironer

A heated revolving ironing cylinder is affixed with a flexible ironing bed drawn taut against the polished revolving cylinder surface functioning to efficiently iron and dry laundry work pieces in a single pass through the ironer. The ironer is comprised of a feed conveyor system delivering laundry work pieces to the top of the revolving ironing cylinder. The flexible ironing bed features holes and anti-friction and anti-static materials to provide a dry, highly polished, static-free laundry work piece. Further ironing efficiency is gained by reduced roller maintenance by means of a roller and air cylinder cooling system.

Heated cylinder ironer utilizing a flexible ironing bed

For operating the rollers and the steam chest in a laundry flatwork ironer a hydraulic system is provided which includes a hydraulic motor for driving the rollers, hydraulic cylinder-and-piston units for raising the steam chest, and a pump for operating the motor and the cylinder-and-piston units. Valves between the pump and the motor are selectively operable to establish low pressure standby operation of the pump with the hydraulic motor off, or low speed operation of the motor to jog the rollers or higher speed operation of the motor to drive the rollers at a speed appropriate for laundry flatwork. Other valves between the pump and the cylinder-and-piston units are selectively operable to raise the steam chest, reduce the cylinder pressure after the steam chest has been raised, and to increase the cylinder pressure whenever laundry flatwork is in the ironer.

Hydraulic system for laundry flatwork ironer

An apparatus for spreading laundry flatwork pieces, such as bed sheets, before feeding them to subsequent processing equipment, such as an ironer and a folder. The flatwork pieces are spread apart by pairs of clamps, there normally being one pair of clamps at the left end, another pair of clamps at the right end, and a third pair of clamps at the center of the apparatus. The spread-out flatwork pieces are blown onto a conveyor for conveying them to the subsequent processing apparatus. Trailing edge sensors are positioned at different levels below the clamps to sense the upward passage of the bottom edge of the laundry flat piece deposited on the conveyor, and a selector switch enables one of the sensors and disables the other, depending upon the speed at which the conveyor is being operated. Proximity switches sense the positions of the clamps. There is an overlying conveyor cooperating with the main conveyor for sandwiching the laundry flat piece as it is moved into the apparatus for stretching purposes. The main conveyor can be moved to an extended position beyond the clamps to facilitate hand feeding of small laundry flat pieces without engagement by the clamps.

Spreader feeder apparatus

This apparatus is for spreading laundry flatwork pieces, such as bed sheets, before feeding them to subsequent processing equipment, such as an ironer and a folder. Separate pairs of flatwork clamps are normally located respectively at the left end, middle and right end of the apparatus. The left end and right end clamps are movable straight across the entry side of the apparatus to the middle before being spread apart. The paired clamps operate to spread their respective flatwork pieces in the order in which their respective start switches are operated manually. Interference among the paired clamps or between the clamps of each pair is prevented. No intermediate flatwork transfer operation is required between the insertion of a flatwork piece into a pair of clamps and the spreading of that flatwork piece.
