A clothes dryer including a housing having a drying chamber, with a perforated clothes drying drum rotatably mounted in the drying chamber. The perforated clothes drying drum is rotated by a belt driven by a motor mounted in the housing, with the motor also driving a blower for drawing air through the perforated drum and drying chamber and for exhausting the air from the housing. The air drawn through the perforated drum and drying chamber is heated by a heater mounted in the housing upstream of the drying chamber. The belt which rotates the drum is directly driven by the motor, with the motor and the drive belt being located within the dryer housing. The belt drive is located in a belt drive chamber of the housing which is a negative pressure zone of the dryer.

An air curtaining apparatus is disclosed that forms a U-shaped air curtain around a steam and heat-emitting piece of machinery, such as a garment form finisher, to protect an operator from heat and moisture emitted during operation of the form finisher while permitting manipulation of a workpiece disposed thereon.

An improved laundry dryer having a novel hot air compartment structure that heats recirculated exhaust air and fresh make-up air. The novel hot air compartment structure, in preferred form, includes an attic chamber defined by the dryer's housing. The attic chamber is divided into upper and lower subchambers, a heater housing being positioned within the lower subchamber. The heat source in the heater housing serves to directly heat fresh make-up air and recirculated exhaust air simultaneously within the heater housing, and also serves to heat up the upper and lower subchambers of the attic chamber. The recirculated exhaust air is introduced into the upper subchamber, thereby pre-heating same prior to introduction into the heater housing, and is subsequently introduced into the heater housing in a vertically downward flow path fashion. The fresh make-up air is introduced into the pre-heated lower subchamber, thereby pre-heating same prior to introduction into the heater housing, and is subsequently introduced into the heater housing in a generally horizontal flow path. The vertically downward and horizontal flow path of the exhaust air and make-up air, respectively, into the heater housing provide for intimate admixing of those two air flows within the heater housing. The flow paths of the recirculated exhaust air and fresh make-up air through the hot air compartment structure is controlled by novel port structure which provides optimum contact of the air flows with the heated surfaces of the upper and lower subchambers, and the heater housing, and with the heat source itself, to achieve maximum heat transfer and, thereby, optimum energy use.

Laundry dryer

A laundry dryer structured to recirculate and reheat a portion of the warm exhaust air, and admix same with newly heated make-up air. A novel hot air compartment positioned within the dryer's housing includes a heat transfer air duct disposed immediately above, and as a part of, a heat transfer chamber. The heat transfer chamber includes a roof above a heat source, that roof comprising the floor of the heat transfer air duct and that roof being heated by the heat source. Recirculated air is directed over the exterior surface of the heat transfer air duct (which is heated by reason of its being proximate to and a part of the heat transfer chamber), and thereafter is directed through the heat transfer air duct. The make-up air heated in the heat transfer chamber exhausts from a port in that chamber's roof into admixed flow with the already preheated, recirculated air as the recirculated air passes through the heat transfer air duct. The compartment also includes a feed duct adapted to direct the admixed recirculated air and make-up air, after the same has been heated to the required temperature level, into the rotating drum of the dryer. This structure serves to reheat the recirculated air, as well as to heat initially the make-up air, without directly contacting the recirculated air with the heat source.

The apparatus includes an elongated buck having an upper convex surface which supports the seam with the edges thereof outboard, and a portable iron having a concave bottom surface and a pointed nose which cooperates with the convex buck to simultaneously open and press the seam sandwiched therebetween as the iron moves in a forward direction thereover. The bottom edge of the iron is recessed on either side of the nose to permit the opened edges of the seam forward of the nose to flow smoothly beneath the iron as the iron advances thereover, preventing bunching of the seam forward of the iron as it advances. A jet of steam directed downwardly and forwardly is emitted from the nose of the iron to moisten the opened seamed edges and thereby enhance the permanency of the overbusting operation. In one form of the invention, the outboard end or nose of the buck, which is inserted into the pant leg when dressing it on the buck, is provided with a smoothly contoured V-shaped notch which guides the seam which is to be overbusted into proper position atop the buck, expediting the dressing operation. Additionally, the buck is provided along its length on its underside surface with downwardly directed compressed air jets which apply a radially outwardly and downwardly directed force against the lower longitudinal one-half section of the pant leg from the interior thereof, in turn pulling the upper seam of a pant leg dressed atop the buck tightly thereagainst to maintain it in position during the overbusting operation.
