Definitions

  • a pair of arms mounted on a pin at the cen- [58] Field of Search 38/93, 77.5, 77.83 ter of the heel plate of the iron carries plugs to close the ports.
  • a single operator button moves the arms to [56] References Cited swing the plugs into or out of the ports.
  • This invention relates to a steam pressing iron. More specifically, this invention relates to an electric steam pressing iron having self-cleaning means, that is, means by which steam may flush accummulated pieces of lint and dust out ports in the rear of the iron to avoid staining the bottom face of the sole-plate. Still more specifically, the invention relates to means for opening and closing such rear flush ports.
  • the present invention presents an improvement over above-identified application.
  • the two plugs may be moved together by the simple movement of a single operator button. This movement may be effected by knocking the button against the side of the ironing board. The opening or closing of the flush ports is thus accomplished in a simple, easy manner favored by by the housewife.
  • the flush ports at the heel of the soleplate are provided with plugs.
  • a pair of rigid arms are pivotally mounted on the heel plate of the iron by a pin disposed on the centerline.
  • the plugs are secured to the ends of the arms respectively.
  • Spring means bias the arms toward the position in which the plugs close the ports.
  • Extensions of the arms are provided with cam surfaces which are engaged by follower means associated with an operating button slideably mounted on the heel plate whereby the arms may close or withdraw the plugs by the limited reciprocal movement of the button.
  • the cam means may be especially shaped to provide a dwell assuring the holding open of the plugs when the button is in its extreme open position.
  • FIG. 1 is a rear elevational view of an iron embodying the invention
  • FIG. 2 is a slightly enlarged bottom plan view of the heel plate of the iron
  • FIG. 3 is a sectional view taken on the line 3-3 of FIG. 1 and showing the plugs in closed position;
  • FIG. 4 is a view similar to FIG. 3 but showing the plugs in open condition
  • FIG. 5 is a sectional view taken on the line 5-5 of FIG. 3;
  • FIG. 6 is a sectional view taken on the line 6-6 of FIG. 3;
  • FIG. 7 is an enlarged view of an operating extension of the arms as shown in FIG. 3;
  • FIG. 8 is an enlarged view similar to FIG. 7 but showing the operation extensions in their locked open position.
  • an iron having the invention embodied therein is designated 10 in FIG. 1. It comprises a soleplate 12, a heel plate 14 secured to the rear thereof, a cover skirt l6, and a handle'member 18. A steam control operator 19 is provided in the handle. Flushing ports 20 are provided in the heel of the soleplate in a manner described in the presently pending application. Plugs 22 and 24 are adapted to close the ports 20 respectively.
  • the heel plate 14 is ofthin sheet metal and is mounted at the rear of the soleplate by a pair of brackets 25 (FIG. 3).
  • a pair of arms 26 and 28 are secured I the means for mounting and operating the plugs of the to the upper side of the heel plate 14 by a pin 30 and to the distal ends of the arms respectively are secured the plugs 22, 24.
  • the arms each have upward tabs 32 and 34, and spring means 36 anchored by the pin 30 bias the anus 26 and 28 with the plugs closing the ports 20.
  • Rearward extensions of the arms 26 and 28 respectively are labelled 26a and 280, as shown best in FIG. 8, and they are each provided with cam openings 26b and 28b. As shown, the openings 26b and 28b are mirror images of each other and are boomerang-shaped.
  • a button 38 is mounted in a slot 40 on the centerline of the heel plate I4 and adapted to be reciprocally moved therein.
  • the button has a stem 38a which extends through the openings 28b and 26b in the rearward extensions of the arms.
  • the upper end of the stem is provided with a head means 42 which holds the button in place but permits its reciprocation.
  • the boomerang-shaped openings 28b and 26b are, in the embodiment shown, configured so that as the button 38 is moved from fore to aft position, the arms are forced open by the stem 38a.
  • the rearward portion of the boomerang-shaped opening provides a cam dwell by which the stem is able to hold the arms with plugs open despite the opposite urging of the spring means 36.
  • the housewife may knock the button 38 to its rearward position against the side of the ironing board, opening the ports 20. She may then press the steam control operator 19 for generation of maximum steam, causing the steam to exit rapidly out the flush ports 20, flushing out the accummulated particles of scorched lint, dust, and so on.
  • the soleplate vents may be blocked by positioning the iron withits soleplate fiat on an impervious supporting surface.
  • the housewife may then knock the button 38 against the edge of the ironing board to close the flush ports 20.
  • the iron is then ready for steam pressing operation.
  • the flushing may be accomplished after the ironing operation, or anytime the operator feels that it is necessary or desirable.
  • An electric pressing iron comprising a soleplate having a steam generating chamber means therein and a plurality of steam vents on the bottom surface thereof; passage means formed in the soleplate to communicate steam to the vents from the chamber means; flush ports in the heel of the iron at either side thereof and connected to the passage means; a heel plate disposed parallel toand slightly above the bottom surface of the soleplate and secured to the heel thereof; a pair of rigid arms pivotally mounted on the heel plate by a pin disposed on the centerline of the iron, the arms having vent plugs secured at their distal ends respectively and adapted to close off the flush ports respectively; each of the arms having cam means; and an actuating button mounted on the heel plate for limited reciprocal movement along the, centerline of the iron, the button having stem means adapted to engage the cam means whereby as the button is moved in one direction, the arms withdraw the plugs from the ports, and when the button is moved in the other direction, the arms move the plugs into the ports respectively.
  • cam means are boomerang-shaped openings and afford a locking surface, holding the arms with plugs away from the ports as the stern means engages the cam means in a dwell area.
