EXHAUST FOR CLOTHES DRIERS Filed June 9, 1952 INVENTOR. 2144 PH 4 BIS/VS o/v,
BY 71J 4920326 ,4 7'TOENEY Patented Oct. 27, 1953 UNITED STATES PATENT OFFICE 7 Claims.
among householders, and have proved themselves highly efficient in drying wet or damp laundry. However, in many instances, the use of a dryer in the basement or laundry of a home has raised to an undersirably high degree the amount of humidity in the air within the home. Addltionally, the moisture-laden air is charged with lint, which is distributed through the interior air of the home and thus creates an undesirable condition.
The broad object of the present invention is to provide a device adapted to be operatively associated with a clothes dryer of the character re- .ferred to, to exhaust to the outer atmosphere the ,moisture and lint laden air issuing from the dryer.
To this end, I provide a device of the type stated 'which, summarized briefly, includes a pair of spaced plates mountable on the inner and outer :surfaces, respectively, of a building wall, said plates being clampably engaged with the wall by a plurality of tie rods extending therebetween,
the tie rods being adapted to space the plates apart a selected distance depending upon the thickness of the particular building wall on which "the plates are mounted. An exhaust duct is extended between the plates, one end of the duct projecting through and beyond the inner plate and being adapted for connection to the exhaust opening of a clothes dryer. The other end of the duct is flush with the outer plate, and is normally closed by a swingable closure panel carried by the outer plate. The closure panel is adjusted to duct opening and closing positions by means of a latch rod connected to the free end thereof and extending between the plates. A latch means is carried by the rod and the inner plate respectively, and is adapted to hold the rod in selected positions in one of which the closure panel is tightly closed and locked, and in the other of which the panel is open.
Among more specific objects of the invention are the following:
First, the provision of a device of the type stated that can be attached to any of various makes of dryers, without requiring modification or redesigning of the same;
Second, the provision of a device as described wherein one form of the device can be mounted on any of various building walls of different thicknesses, by utilization of a clamp type plate-connecting means that does not require the bolting or screwing of the device directly to the wall;
Third, the provision of a device as described wherein a closure panel latch means is adapted to hold said panel tightly closed and locked when the dryer is not in use, thus to prevent the admission of cold air, insects, or dampness into the basement or home laundry; and
Fourth, the provision of a device as described that can be manufactured at relatively low cost, will comprise a minimum of parts simply arranged in a manner whereby they will not readily get out of order, and will be capable of installation by a homeowner with a minimum of difliculty and without requirement of special tools.
Other objects will appear from the following description, taken in conjunction with the annexed drawing, wherein like reference numerals have been applied to like parts throughout the several views, and in which:
Figure 1 is a perspective View of an exhaust device for lint and moist air formed in accordance with the present invention, as it appears when mounted in a building wall, said wall being illustrated fragmentarily and in section;
Figure 2 is a longitudinal sectional view on a reduced scale, taken substantially on line 2-2 of Figure 1;
Figure 3 is an end elevational view, taken from the right of Figure 2;
Figure 4 is an enlarged detail sectional view, showing the connection of the operating rod to the closure panel; and
Figure 5 is a sectional view on line 5-5 of Figure 3.
The exhaust device includes outer and inner plates l0, l2 mountable against the outer and inner surfaces, respectively, of a building wall W. In this connection, it will be understood that an opening of substantial size is initially formed in the building wall, the plates overlying the respective ends of said opening. To provide a weather and insect proof means engageable between the respective plates and the building wall, sealing members I4, formed of soft rubber or other compressible material, are interposed between the respective plates and the inner and outer wall surfaces. The members i l have their outer edges flush with the peripheries of the respective plates l0, l2.
In the plates 1 2 and It I form large center openings l6, 13 respectively, said openings being aligned transversely of the building wall and bemg here shown as circular, although they may 3 be of other shapes if desired. The sealing members Mhave large openings 26 of rectangular configuration, formed to a size substantially greater than that of the openings l6 and It.
For the purpose of securing the plates in place against the inner and outer wall surfaces, I utilize a plurality of tie rods 22 each of which is threaded at its opposite ends. The tie rods are extended through corner openings formed in the respectiveplates i5, i2, and are disposed within the opening of the wall.
After the tie rods have been extended through the corner openings of the respegtive plates, nuts 24 are threaded upon the opposite ends thereof, against the outer surfaces'of the respective plates. It will be noted, this regard, that the plates and tie rods can be mounted upon building walls of varying thicknesses. On any wall on which they are mounted, the plates will be forced into tight, clamping engagement with their adjacent wall surfaces, when the nuts are threaded inwardly on the opposite Ends of the tie rods, the members 14 being compressed against the wall surfaces to seal the Wall opens ing at its ends, through an area extending marginally of the plates.
Carried by the respective plates l5, i2 is a duct 26, formed open at its ends and fitted snugly within the openings [6, It said duct extending transversely of the building wall between the plates in and I2. One end of the duct is disposed flush with the outer surface of the plate it (Figure 2), and is fitted snugly within the opening 18 of said plate. The other end of the duct is projected inwardly of the building, beyond the inner plate i2, and is snugly but slidably fitted within the opening Iii of said inner plate. Thus, when the plates are shifted toward one another into clamping engagement with the building wall, the projecting 'inner end of the duct is permitted to slide within the opening Iii, to any extent necessary. After the plates have been clamped to the wall, the innen end of the duct is connected in communication with the air outlet of a conventional clothes dryer, not shown.
Means is embodied in the device for controlling the opening and closing of the duct whenever the device is to be used. This means includes spacer '28 interposed between a hinge 3i] and the outer surface ofplate I0, screws or equivalent fastening elements being extended through one leaf of said hinge and through the spacer into the plate. The other hinge leaf has connected thereto a closure panel 32 proportioned to cover the open outer end of the duct 26 and adapted, when closed, to be shifted into engagement with said outer end.
Formed in the outer plate I0 is a slot 34 communicating with the opening N3 of said plate. A latch rod 36, extended in parallelism with and spaced away from the duct 26, is threaded at one end, the threaded end of the rod extending through the slot and through an aperture 38 formed in the closure panel. As will be noted from Figure 4, the aperture 38 is formed to a size substantially greater than the diameter of the rod 36, so as to prevent the rod from binding within the opening when the closure panel is being swung between its open and closed positions.
Threadedly engaged with the outer end of the rod 36, are nuts 40, one of said nuts being disposed a a ns th oute s r o th lat 30 an W111 be noted, can be adjusted longitudinally of the rod 36, so as to accommodate the same to the adjusted distance between the plates l0 and [2, it being mainly important that the nut 40 shown at the left in Figure 4 be engaged against the outer surface of the plate 30 in the closed position of the closure panel.
The other or inner end portion of the rod 36 is extended loosel through an opening 42 pro-' vided in the inner plate 12 and is projected interiorly of the building wall, the projecting inner end of the rod being bent to form a closed. loop extending radially of the rod to provide a handle 44. The loop is of rectangular formation, having an inner portion 46 disposed normally to! the axis of the rod 36.
A latch member 48 is secured to the inner plate I2, and is formed from a single length of flat bar material bent to shape, the opposite ends ofv said length of material being turned outwardly to form feet abutting against the plate 12 and. fixedly secured thereto by screws or equivalent fastening elements. The medial portion of the. latch member is formed to a U-shape, the legs: of said medial portion extending outwardly from. the plate I2 and merging into a bight 50 extend-- ing obliquely to the plane of the plate to form. a cam surface extending across the path of swings. ing movement of the portion 46, when the closure.- panel is closed and the rod 36 is rotated.
Secured to the inner plate 12, adjacent the latch member 50, is a keeper 52 having a free v end portion offset outwardly from the inner plate,.
(ill
th the bein d sp s n spac d reletiq to the inner surface thereof. The nuts 36, as
though not to so great an extent as that to which. the bight 59 is spaced away from said plate.
By reason of this construction, it will be noted. that when the closure panel is swung to a closed position, the handle 44 can be swung from the. dotted line position to the full line position there-- of shown in Figure 3. As a result, the portion. 46 of the handle will be engaged by the cam. surface of the latch member and continued T0,?- tation of the handle in the same direction will. be effective to bind the portion 46 against-the cam surface, with said surface being operative,
to shift the rod in the direction of its length away from the closure panel. Thus, the closure. panel will be forced into a tightly closed position, and will be locked in said position.
At such time as the dryer is to be again used, the handle is swung counterclockwise in Figure 3, freeing the rod for longitudinal movement in an opposite direction, to open the closure panel, When the panel has been opened, the handle extended into the keeper 52 to hold the. panel in the open position thereof.
