Description
March 12, 1957 L. J. JENN VENTILATING DEVICE Filed Jan. 26, 1953 array/m United States Patent VENTILATING DEVICE Louis J. Jenn, Indianapolis, Ind.
Application January 26, 1953, Serial No. 333,146
4 Claims. (Cl. 98-116) This invention relates to a ventilating device for a room or building, and while the same might have various applications, it is particularly designed to be attached to a wall and to draw air through a passage in said wall.
It is an object of this invention to provide a very simple, compact and efiicient ventilating device which can be easily assembled and disassembled and which can be very easily installed in operative position in conjunction with a passage extending through a wall.
It is also an object of this invention to provide a ventilating device comprising a member or housing of semidome shape and having a peripheral flange adapted to be secured against a wall about a passage therethrough, a second member having an outer substantially semispherical portion having an outwardly extending cylindrical portion cooperating with a conduit extending through said passage, brackets secured to said second member, a plate secured to said brackets and a motor secured to said plate, said motor having a fan secured to its driving shaft and disposed within said semi-spherical portion.
It is more specifically an object of the invention to provide a ventilating device cooperating with a conduit extending through a passage in a wall, said device comprising a member or housing having a concave annular portion with its concave side directed toward said conduit and wall and having a peripheral flange adapted to be secured to said wall, a second member having a substantially semi-spherical portion with its concave side directed outwardly away from said wall, the outer portions of said members being in engagement and secured together, said second member having a cylindrical portion extending into said passage and conduit, spaced supporting means secured to said semi-spherical portion and extending outwardly therefrom, a plate secured to said supporting means, a motor secured to said plate having its driving shaft directed toward said conduit, a fan secured to said shaft and disposed within said semispherical portion and a cover secured to said plate surrounding and spaced from said motor.
These and other objects and advantages of the invention will be fully set forth in the following description made in connection with the accompanying drawings in which like reference characters refer to similar parts throughout the several views and in which:
Fig. 1 is a central vertical section through the device and the wall to which it is secured; and
Fig. 2 is a view in elevation as seen from the left of Fig. 1.
Referring to the drawings, a device is shown adapted to be connected to a wall 10. Said wall has a passage a therethrough shown as of cylindrical form. A conduit 11 fits in and is disposed in passage 10a, the same having a peripheral flange 11a at its outer side which will be secured to the outer side of wall 10 in any suitable manner, as by a plurality of circumferentially spaced screws 12. A support 14 is provided, and while this might be of various forms, in the embodiment of the 2,784,661 Patented Mar. 12, 1957 ice invention illustrated, it is shown as an angle bar extending vertically and diametrically across conduit 11 and secured thereto. A damper or vane 16 is pivoted to the bar 14 by a pivot 17, said pivot being disposed some distance above the center of damper 16 and conduit 11.
A member or housing 18 is provided, the same being of annular form and having a curved portion extending inwardly toward the axis of conduit 11, said member thus having a concave side which is directed toward wall 10. Member 18 has a peripheral flange 18a adapted to engage the inner side of wall 10 and be secured thereto by any suitable means, such as the circumferentially spaced screws 19. A second member 2i) is provided, the same having an outer substantially semi-spherical portion 20a which has its concave side directed away from wall 10. The outer portions of members 18 and 20 or the portions farthest from wall 10 are in engagement and secured together, the same being rolled outwardly to form a bead 18b. This bead forms the outer edge of said members. Member 20 has an inner cylindrical portion 20b which extends into conduit 11. A part of the portion 20b is offset inwardly at the point 200 and conduit 11 extends over and fits about said part.
A plurality of brackets 22 are secured to the inner side of portion 20a, the same being shown as of annular form and extending outwardly in a substantially horizontal direction. A plate 23 engages the outer ends of brackets 22 and said brackets are secured to plate 23 and to portion 20a by the headed screws 24. Washers 25 underlie the heads of the screws 24 which secure plate 23. An electric motor 26 is secured to plate 23 by a plurality of circumferentially spaced bolts 28, said bolts extending through washers 29 disposed at each side of plate 23 and which will be made of rubber or other suitable insulating material which is preferably resilient. Motor 26 has a driving shaft 26a directed toward conduit 11, and a fan 30 is secured to shaft 26a. The fan 30 may be of any multibladed and efiicient type. Plate 23 has a central opening 23a therein through which shaft 26a and a portion of a hub on said motor project. Plate 23 has a peripheral flange 23b offset outwardly to which is secured a cover 32. Cover 32 is shown as secured by a plurality of circumferentially spaced screws 33. Cover 32 has an outer peripheral flange from which extends a semi-dome portion, and said cover has a substantially cylindrical portion at its front. Cover 3?. surrounds motor 26 and is spaced therefrorm The front cylindrical portion of cover 32 is provided with a multiplicity of slots or louvers 3212. It will be seen that members 18 and 20, plate 23, motor 26 and cover 32 are all coaxial with conduit 11. The inner portion of cover 32, plate 23 and fan 30 are disposed within the semispherical portion 20a.
In operation, the motor 26 will be driven and fan 39 will be rotated. Air will be now drawn outwardly through the conduit 11 as indicated by the arrow, and discharged from the room through the annular passage adjacent to ring 18b. The damper 16 will swing outwardly to permit this outward movement of air and when motor and fan are stopped, damper 16 will swing to a substantially vertical position and prevent cold air from the outside passing through conduit 11. It will be seen that the present structure is very compact. As stated, the bead 18b forms the outer edge of members 18 and 20 and any liquid or moisture which might collect on the inner surface of portion 20a Will drip from said bead. It will be noted that cover 32 is separate from motor 26 and can be easily removed without disturbing motor 26. When the cover 32 is removed, the motor with fan 30 can then be removed with plate 23 by merely removing the screws 24. Most of the parts are made from sheet material which preferably will be aluminum. These parts can be stamped out and thus made quite economically. The device also has great utility and efiiciency as a roof exhauster.
The device has been amply tested in actual practice, found to be very successful and'efiicient and is being commercially made.
It will of course be understood that various changes may be made in the form, details, arrangement and proportions of the parts, without departing from the scope of applicants invention, which, generally stated, consists in a device capable of carrying out the objects above set forth, in the parts and combinations of parts disclosed and defined in the appended claims.
