2. Description of the Related Art
Numerous machines have been provided for the purpose of steaming, ironing and pressing garments after washing operations. Each prior device typically is configured to allow an article of clothing to be positioned on at least one supporting member such as a vertically oriented buck, which is moved against a pressing surface for the application of pressure from steam heated surfaces, and/or hot air to remove wrinkles from the article of clothing. Typically a shirt, coat, or a pair of pants is positioned on a surface of a buck for a series of sequential pressing operations. The series of sequential operations require positioning and, if necessary, repositioning of the article of clothing by the operator, and further requires a multitude of operating steps before the pressing of the article of clothing is completed. After completion of the operating steps, touch-up ironing by an operator may be required to provide adequate removal of wrinkles along a shoulder seam and/or a back of a shirt. Prior art devices related to pressing garments such as shirts and blouses are disclosed in U.S. Pat. No. 3,471,067, issued to Stewart, on Oct. 7, 1969, and U.S. Pat. No. 5,732,859, issued to LeBlanc, on Mar. 31, 1998.
An improved sleeve pressing apparatus is needed to provide an apparatus for completing a series of coordinated operations including positioning, extending, and pressing of an article of clothing in concert with a shoulder tensioning system for removing wrinkles with minimal positioning of the article of clothing by an operator and minimal touch-up ironing by an operator.
In accordance with the present invention, there is provided a sleeve pressing apparatus and shoulder tensioning system for tensioning the shoulder seams of a shirt to remove wrinkles during drying and pressing operations of an article of clothing such as a shirt. One embodiment of a sleeve pressing apparatus is an apparatus configured to accept thereon any of a variety of sizes of a shirt or a coat having a pair of sleeves and shoulder seams to be pressed. The sleeve pressing apparatus includes a supporting means for extending and positioning each sleeve for drying and pressing of each sleeve in concert with a shoulder tensioning system that provides tensioning means for removing wrinkles from each shoulder seam area of each sleeve. The supporting means of the sleeve pressing apparatus includes a pair of sleeve holders attached to a means for pivoting connected to the cabinet. The sleeve holders are disposed in a first position in a substantially parallel and spaced apart orientation extended above a mounting shelf for positioning the sleeves of a shirt on each respective sleeve holder. The pair of sleeve holders are positioned by pivoting to a second position in which each shirt sleeve is disposed between a pair of elongated pressing members for drying and pressing of the shirt sleeves.
A shoulder tensioning system is positioned within the sleeve pressing apparatus and includes a first and a second grip arm disposed to be extendable from respective first and second pistons concurrent with the operation of the sleeve pressing apparatus. Each grip arm includes a gripping end that is extendable against each sleeve shoulder seam concurrently with actuation of the pressing members of the sleeve pressing apparatus. A timing control device provides proper timing for extension of each gripping end to maintain tension against each sleeve shoulder seam concurrently during the sleeve pressing operation. Wrinkles in the shoulder seam area of each sleeve are concurrently removed by the shoulder tensioning system without an operator having to reposition either shirt sleeve for removal of wrinkles during operation of the sleeve pressing apparatus.
The above-mentioned features of the invention will become more clearly understood from the following detailed description of the invention read together with the drawings in which:
