2 Claims. (Cl. 126299) This invention relates to improvements in ventilating hood assemblies for, and in combination with, stoves, cooking ranges, and other devices giving off smoke, heat, vapor, fumes, and other objectionable eifiuvia.

The primary object of the invention is to provide more efficient and practical ventilating devices of this kind which are easily movable at will between operative positions wherein the hood components are in suction relation to and substantially directly above the efiluviaproducing element or elements, such as burners of a stove or range, and inoperative or stored positions wherein the hood components are out of the way, as behind and below the stove or range and its burners, the hood components being adjustable in their operative positions so as to enable placing the hood components relative to groups of burners or single burners for obtaining different desired ventilating effects.

Another object of the invention is to provide devices of the character indicated above which can be made in decorative forms and/or combined with cookin ranges and the like in ways to enhance the overall decorative appearances thereof.

A further object of the invention is to provide devices of the character indicated which are simple and uncomplicated in construction, are composed of small numbers of simple and easily assembled parts, are easily installed on incorporated in such as ranges, and which can be made in rugged, wellfinished, and serviceable forms at relatively low cost.

Other important objects and advantageous features of the invention will be apparent from the following description and the accompanying drawings, wherein, for purposes of illustration only, a specific form of the invention is set forth in detail.

In the drawings:

Figure 1 is a front perspective view of a cooking range having thereon a ventilating hood assembly of the invention;

Figure 2 is an enlarged fragmentary vertical transverse section taken on the line 22 of Figure 1, the hood components being shown in inoperative and operative positions in full and in phantom lines;

Figure 3 is a fragmentary front elevation of a cooking range having thereon another form of the invention;

Figure 4 is a fragmentary transverse vertical section, taken on the line 44 of Figure 3, showing the hood component in inoperative position; and,

Figure 5 is a similar section, showing the hood component in an operative position.

Referring in detail to the drawings wherein similar and related numerals designate like parts throughout the several views, the numeral 20 generally designates a cooking range of substantially conventional form, having a horizontal cooking surface 22 having therein burners 24, and an upstanding back wall 26 along the rear of the surface 22.

The form of the invention shown in Figure: 1 and 2 PP C3 comprises a horizontally elongated hood 38d, composed of either a single hood form or of several hood forms arranged in line. The hood 38d has a central rearwardly extending neck 40d on its bottom wall 70, on which is secured the upper end of a flexible conduit 42d, which depends behind a range 20, and whose lower end is adapted to be connected to an outlet or to a suitable source of suction (not shown).

The hood 38d has a lower horizontal wall 72 which coextensively overlies the top 74 of the range back wall 26, the hood 38d being substantially as long as the back wall 26. A forwardly opening hinge 76 has its hinge leaves severally secured to the hood bottom wall 72 and the top 74 of the range back wall 26, whereby the hood 38d is stopped and supported in a vertical storage or inoperative position, as shown in full lines in Figures 1 and 2, when hinged upwardly and rearwardly from a forward horizontal operative position, shown in full lines in Figure 2, wherein the hood 38d is supported by engagement thereof with the range back wall 26.

In the form of the invention shown in Figures 3 to 5, and which is preferred for built-in factory installation in a range incorporating the invention, the hood assembly, generally designated 36d is of dual construction and comprises two substantially similar front and rear sections 80 and 82, respectively, which are movable relative to each other, from inoperative side-by-side stored positions, to differently angulated operative positions relative to each other and to a range 20.

The sections 80 and 82 are elongated fiat hollow bodies having top and bottom walls 84 and 86, front and rear curved side walls 88 and 90 and closed end walls 92. The bottom walls 86 have therein elongated rectangular suction openings 94 in which are seated and secured suitable screens 96. Extending between and secured in openings 98 in related side walls 88 and 90 of the sections, at points intermediate the ends of the sections are the opposite ends of a short flexible conduit 42a, which puts the sections in suction communication with each other. Hinge links 100 extend between the sections in the regions of said related side walls 88 and 90 and are frictionally pivoted at opposite ends, as indicated .at 102 and 104 to related end walls 92 of the sections, so that the sections are frictionally held in different angular relations to each other. The top wall 84 of the front section 80 has therein a handle 106 for adjusting the sections.

Secured in and traversing the top 74 of the range back wall 26 is a rigid vertical suction pipe 50e, which extends within the interior of the back wall 26 and has a horizontal lower end portion 108 extending rearwardly from the back wall 26, for connection to an outlet or to a suitable source of suction (not shown). Fixed on the upper end of the pipe 50a, above the back wall 26, is an open halfcircular cross section channel 110 which is rotatably or swingably engaged with the inner side of the curved rear side wall 90 of the rear hood section 82, with the pipe 50a engaged in a slot 112 which extends crosswise in the side wall 90, whereby the rear hood section 82 can be swung forwardly from the erect perpendicular inoperative position shown in Figure 4, as shown in Figure 5. The side wall 90 bears upon a washer 114 provided on the top 74 of the back wall 26 around the pipe 50e, whereby the channel 110 is maintained in engagement with the inner side of the side wall 90.

As indicated in Figure 5, the hood sections 80 and 82 can be selectively adjusted relative to the range back wall 26 and the range burner surface 22 and to each other, to produce different desired vapor withdrawing effects relative to burners 24 on the burner surface 22. It is obvious that the various devices of the invention could, with or without modification thereof, be used to draw 05 vapors from apparatus other than cooking ranges.

.Although there has been shown and described herein a'preferred form of the invention, it is to be understood that the invention is not necessarily confined thereto, and that any change or changes in the structure of and iri the relative arrangements of components thereof are contemplated as being within the scope of the invention as defined by the claims appended hereto.

1. A suction ventilating device comprising a hood, a vertical suction pipe having an open upper end, said hood comprising a first section and a second section, said sections being substantially coextensive, said first section having imperforate top, bottom and rear walls and a perforate front wall, said bottom wall having a suction opening with which said open upper end of the suction pipe is in communication, said second section having imperforate top, bottom, and rear walls and a perforate front wall, a first hinge means hinging the bottom wall of the first section to the upper end of the suction pipe, a second hinge means connecting the top wall of the first section to the bottom wall or the second section for hinging the second section toward the first section so as to register the perforated front wall of the second section with the perforated front wall of the first section, and conduit means providing communication between said sections.

2. In combination with apparatus having a vaporproducing surface, of a hood assembly having a vapor receiving opening means normally facing and positioned over said surface, a neck on and communicating with the interior of the hood assembly, and a bendable suction conduit having a first end supportably and flexibly mounted on the apparatus at a location at one side of said surface, said conduit having a second end supportably connected to and communicating with said neck, said hood assembly comprising a first pan-shaped section scre References Cited in the file of this patent UNITED STATES PATENTS 140,996 Douglas July 22, 1873 245,689 Young Aug. 16, 1881 514,003 I-Iornor et al.
