United States Patent TAKE-APART KITCHEN RANGE HOOD Sidney Simon, Los Angeles, Calif.

Application November 5, 1956, Serial No. 620,497 2 Claims. (Cl. 95-115) This invention relates to a fume hood, and particularly to a hood for mounting above a cook stove for the removal of cooking vapors and odors.

Fume hoods, such as the type used above kitchen ranges, become coated with a film of grease in a relatively short time. Dust adheres to this grease film, and the inside and outside surfaces of the hood soon present anunsightly appearance. To remedy this, the hood must be cleaned periodically both inside and outside.

The vapors from cooking foods contain a considerable amount of water. A portion of this water and other liquid material cooked 0133 of the foods condenses on the surface of the hood, especially the inside surface. These condensed vapors attack paint and discolor the surface of the hood. Eventually cracks form in the paint film and corrosion commences to take place on the exposed sheet metal surfaces of the hood. These results must be remedied from time to time by thoroughly cleaning the inside surface of the hood and by repainting it.

To reduce the amount of labor involved in cleaning and painting such hoods, it is highly desirable that ready access can be had to the inside surfaces of the hood. If such access cannot be had, it becomes extremely difiicult and sometimes impossible to adequately clean or paint the inside surface of the hood because of an inconvenient location of the hood above a cook stove, and near to a vertical wall and a horizontal ceiling. As a result, such hoods usually receive inadequate attention and their life span is shortened by rusting through of the sheet metal of which the hood is made, or by the development of an extremely unsightly or unsanitary condition on the inside of the hood beyond the point where the hood can be cleaned or cleaned and painted by the exertion of reasonable amount of effort or expense.

Accordingly, it is an important object of my invention to provide a fume hood characterized in that a portion thereof can be temporarily removed for the purpose of providing ready access to the inside of the hood for cleaning or painting purposes.

Another object is to provide a hood for a cook stove whichcan readily be cleaned or painted on the inside thereof periodically with the exertion of a minimum amount of effort and with a minimum of inconvenience.

A further object is to provide a kitchen range hood of low cost sheet metal construction efiiciently designed for ready access to the inside surface thereof, for the purpose of periodically cleaning condensed grease and dirt from the surface of the hood.

Additional objects will become apparent from the following description:

Stated in general terms, my invention comprehends the provision of a fume hood comprising a body portion and one or two wing portions attached to the body portion. The body portion usually is of generally rectangular construction and is provided with an opening in one or both sides thereof extending from approximately one end of the body portion to the other, and from the bottom to substantially the top thereof. Each wing portion is detachably mounted on the side of the body portion in align ment with this opening.

The wing portions preferably are pivotally mounted on the body portion and preferably are constructed to extend outwardly of the body portion from the ends and the tops of the openings and from the sides of the body portion. This construction permits the rapid and convenient. periodic removal or pivoting of the wings relativeto the body portion so that easy access can be had to the inside surfaces of the hood from one or both sides thereof, for the purpose of cleaning or painting the same.

A more detailed description of a specific embodimentwherein:

Figure 1 is a perspective view of one embodiment of the hood of my invention showing a body portion and one wing portion in solid lines and a second wing portion in phantom; I

Figure 2 is a partial cross-sectional view of the right side of the hood shown in Figure 1 showing the normal position of the wing portion relative to the body portion of the hood in solid lines, and showing the wing portion pivoted upward for ready access to the inside surfaces of the hood in phantom;

Figure 3 is a partial sectional view drawn to an en-' larged scale showing a detail of one of the pivot posts about which the wing portion of the hood is pivoted upward for ready access to the interior surface of the hood; and

Figure 4 is a partial perspective view drawn to an enlarged scale showing a detail of one of the clips mounted on each side of the opening in the body portion for aligning the wing portion with the body portion.

In the embodiment of my invention shown in the drawing, the body portion 10 of the hood is made of sheet metal such as steel or aluminum sheet. The top 11 of the body portion and the front 12 and corresponding back portion are made in one piece cut to size. An open-I ing 13 for a ventilating fan and bolt holes 14 are cut into the top 11. An electric cable opening 16 also is cut in the top 11 and electric cord openings 17 are cut into the front portion 12. The edges of the body portion are doubled back as shown at 18 to eliminate any exposed sharp edges and to increase the strength and rigidity of the sheet metal structure.

A suitable bracket 19 is made of sheet metal or other suitable material and is adapted to holda socket for a light, and plug-in means for a motor and for electric wiresv connected to a voltage source. The bracket 19 is attached to the inside surface of the top 11 of the hood by' suitable means, such as by spot welding or brazing.

Two vertical end portions 21 are made with top border.

portions 22 bent inwardly at right angles and with similar are fitted on the ends, front 12 and back of the top 11,"

with the borders 22 overlapping the ends of the top 11, as best shown in Figure l. The end portions 21 are then attached to the top 11 by spot welding or brazing at points along the border portions 22. The end portions 21 also are spot welded or brazed to the front 12 and rear of the body portion 10 along the borders at which the various portions meet.

A clip 26 is riveted to the insides of each of the end portions 21 adjacent the lower and vertical edges thereof, as best shown in Figure 4. Each clip 26 contains a flush portion 27 which is riveted against the inside of the end portion 21. The clip 26 also contains a vertical portion 29 spaced from the inside surface of the vertical edge 31 of the end portions 21.

A pivot post 3'2 is mounted adjacent the vertical edge 31 of each end portion 21 of the body portionof the hood, at a point somewhat above the midpoint between the bottom of the end portions 21 and the lower edge of the front 12, as best shown in Figure 2. The posts 32 are mounted in alignment with each other to 'form a pivotal axis for a front wing 33 and also a rear wing 34, if a second wing is employed, as shown in phantom in Figure 1. Each pivot post 32 is generally cylindrical and preferably is flanged at its attached end, as shown at 36. A tapped hole is formed in the flanged end and a screw 37 is passed through a hole drilled through the doubled edge portion 31 of the end portion 21, and is threadedly engaged in the tapped hole to firmly'hold the post at right angles to the edge portion 31 of the end portion 21.

The wings 33 and More made of similar construction with the exception that one of them is a right-hand and the other a left-hand,'or mirror image, member. For the sake of simplicity, only the one wing 33 will be described. A top 38 of the wing is concavely curved and is provided at its upper edge with a narrow horizontal portion 39 and a narrow vertical portion 41 doubled back, as best shown in Figure 2. The wing 33 also is provided with a lower vertical portion 42, which is curved inward horizontally at the lower edge thereof, and doubled back at 43. In addition, the wing 33 is provided with an end 44 at each end thereof. The ends 44 are cut to fit, and the top curved edge 46 thereof, as well as the vertical forward edge 47 and the bottom edge 48, are turned inwardly at right angles. The top edge portion 46 and the front edge portion 47 fit within the curved portion 38 and the vertical portion 42, respectively, of the wing. The resulting joints are secured by spot-welding or brazing, as described above. The bottom edge portion 48 also is doubled back as previously described.

' The inner vertical edge 49 of the end portions 44 of wing 33 are doubled back for rigidity and strength. An arcuateslit 51 is properly positioned and shaped so that it can be hooked over a pivot post 32 and so that the wing 33 can be inserted into the opening above the post for such hooking engagement, and so that the wing 33 can be pivoted upwardly as shown in phantom in Figure 2, or positioned in alignment with the vertical end portions' 21 of the body portion 10, as best shown in Figure 1. The vertical edges 49 of the wing 33 are positioned between the spaced portion 29 of the clip 26 and the vertical edge 31 of the end portions 21 for perfect fitting of the wing '33 on the body portion 10. The vertical edge 49 is curved at the bottom thereof as shown, so that free pivotal movement of the wing 33 can be had when it is pivoted upwardly out of normal position or downwardly into position.

, It will be seen that whenever it is necessary or desir-able to clean, or clean and repaint, the inside surface of the hood, all that is necessary is to grasp the wing 33 at the vertical portion 42 and swing it upwardly by pivoting the wing on the pivot posts 32, as shown in phantom in Figure 2 The inside surface of the wing 33 (and 34) can very readily be cleaned in this position.

If desired, however, the wing 33 can be slipped out of engagement with the body portion 10, and completelyremoved, for better access to the inside surface of the wing 33 (and 34) and the body portion 10. The inside surfaces of the hood then can very readily be cleaned, or cleaned and repainted, with a minimum of inconvenience and in the shortest possible time.

While I have herein shown and described my invention in what I have conceived to be the most practical and preferred embodiment, it is recognized that departures can be made therefrom within the scope of my invention, which is not to be limited to the details disclosed herein, but is to be accorded the full scope of the claims so as to embrace any and all equivalent'structure.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:
