(Cl. 126-339) My invention relates to stove construction, and out position; for cooking stoves. ' Fig. 2 is a perspective view of the same stove with the oven door shut and the pull out con struction concealed on the inside of the stove; Heretofore it has been di?icult to inspect food Ca being cooked in the ordinary cooking stove ovens, as it was necessary to slide out the shelf on which the food was resting by manual manipulation. The shelf was of course hot and had to be handled with a protective device for the hand. At the 10 same time there was danger of burning the hands, as well as inconvenience in time consumed in making the inspection since the shelves with their heavy weight of food upon them were often There was further danger that the shelf would be pulled out too far, allowing the‘ food to be spilled on the floor. These and other incon veniences and disadvantages of former construc tions are in a large measure overcome by the 20 present construction. It is an object of my invention to devise an oven wherein the food on the shelves can be readily inspected at all times during the cooking operation. A further object of the invention is to devise a construction which will move out the shelf or support on which food is resting so that it will project beyond the front of the oven and can be readily inspected. 30 ‘ ' 5 Fig. 3 is a sectional view taken through the oven and the pull out construction showing the position of the parts in the pulled out position; Fig. 4 is a view taken along the line 4-4 of Figure 3, looking in the direction of the arrows; 10 Fig. 5 is a view taken along the line 5—5 of Figure 3, looking in the direction of the arrows; Fig. 6 is a detail perspective view of one of the holding members, and a portion of the sliding hard to move. 15 ing my pull out oven construction in the pulled more particularly to the construction of ovens Yet another object of the invention is to pro vide a construction which will accomplish the above, which is simple, sturdy and inexpensive support; 15 Fig. 7 is a. view taken along the line 1-1 of Figure 5, looking in the direction of the arrows; Fig. 8 is a detail perspective view of a modi ?cation of the sliding support member equipped with a novel form of shelf support frame. 20 Referring to the drawings I have shown a stove l having an oven 2 having side oven walls 3 and 4. On the side oven walls are grooved tracks 5 in which are adapted to slide shelves 8 which are generally of the usual open bar con- 25 struction. The oven is provided with a top ‘I. The side walls 3 and 4 and the top ‘I are in sulated, as indicated in the drawings, with some suitable insulating material. The lower portion of the side wall 4, which I have designated by 30 the numeral 8, is not insulated, as it abuts against a compartment 9 in which is adapted to be placed food to be kept hot. to manufacture. A still further object of the invention is to provide a construction which is easy to repair and replace and in which there are few operating bottom I0 which is provided with airholes, not 35 parts. element of the usual construction H, which lies With these and other objects in view, which may be incident to my improvements, the inven tion consists in the parts and combinations to be hereinafter set forth and claimed, with the understanding that the several necessary ele ments comprising my invention may be varied in under a, baille plate l2 composed of a lower me tallic sheet member l3 and an upper metallic sheet member l4. The upper metallic sheet 40 member I4 is riveted or otherwise suitably at tached to an insulated rear wall l5 of the oven 2, and also at the front end to a front wall construc construction, proportions and arrangement, without departing from the spirit and scope of the appended claims. The oven is provided with a metallic sheet shown. There is placed in the oven a heating tion l6, which comprises a relatively narrow strip across the front of the oven. 45 in their useful applications to the particular con There is provided an aperture H in the front wall in which is adapted to slide a sliding frame l8 having an insulated front wall l9 which ?ts‘ within the aperture ll of the oven front wall l6 when the sliding support I8 is in the closed posi- 50 tion. Hinged on the front wall I6 is an insulated structions, which, for the purpose of explana oven door 20. tion, have been made the subject of illustration. In the drawings: Figure 1 is a perspective view of a stove show Attached at one side of the front wall IQ of the sliding support I8 is an upstanding handle sup port 2| which substantially at its mid-point car- 55 In order to make my invention more clearly understood, I have shown in the accompanying drawings means for carrying the same into prac 50 tical eifect without limiting the improvements 2 2,130,167 ries a handle 22. The handle 22 can be grasped by the hand of the user and the sliding support I8 either slid into the oven or pulled out. In the inner position the door 20 is closed, as shown in Figure 2. In the outer position the sliding support I8 carries with it the shelf 6. Carried at the back of the sliding support I8 are two members 23 which may be fastened by bolts 24 to the inside of a tray 25', which is fas 10 tened at its front end to the front I9 of the sliding support I8.~--.These two members 23 are of ?at metal and are provided with forwardly extending arms 25. The members 23 are notched, as indicated at 26. A roasting oven bottom 21 of sheet metal has a downturned ?ange 28 which ?ts into the notches 26 of the members 23, and the downturned ?ange 29 which ?ts over the end of the arms 25. The bottom 21 of the roast ing oven can be used to support food being 20 cooked, as also can any of the shelves 6. Holding members 30 are attached by bolts 3| to the members 723. The holding members com prise upstanding arms 32 having inwardly pro jecting lugs 33 which ?t over slots 34 formed in sliding lock members 35. The lugs 33 are provided with ‘enlarged heads which prevent them from coming out of the slots 34. The lugs 33 30 may be riveted in place on the arms 32, or otherwise suitably attached. ' Each sliding lock member 35" is provided with notches 36 and downwardly projecting catches 31 which are adapted to fit over the rearmost wire of one of'the?trays? to_hold the tray 6 securely to each holding member 30. When the 35 sliding_locking. members 35 are in the raised position, however, the catches_31 do not engage the rearmost wire of the shelves 6, and the shelves 6 may freely slide in the grooved tracks 5. Ordinarily the .pull of gravity on the sliding loclrniembers 35 holds them in the down posi tion, as indicated in Figure 3. In the rearmost position, however, of the sliding support I8, rollers 45 38 mounted- on the sliding lock members 35 en gage cams 39 ail‘lxed to the rear wall I5 of the oven 2. » These‘rollers 38 contacting .with cam surfaces on-cams 39 raise the sliding lock mem to bers 35,‘ releasing the rearmost wire of each shelf or tray 6. "In this position of the parts, when the front door 20 is downeach shelf or tray 6 can be slid in its‘ grooved tracks 5 by manual _ - , , . which bear against tracks 46 carried by the bottom of the tray 25'. This construction gives a cantilever supporting effect to the sliding support I3, the tray sliding on rollers 45 and being held from tipping by the action of rollers 42, see Figure 3. This construc tion permits of great ease in pulling in and out the sliding support I8. In order to strengthen the tray 25', I have shown bracing elements 41 which are suitably 10 attached by bolts 48 to the sides of the tray 25'. In order to prevent the support from being pulled out too far, I have shown downwardly curved arresting surfaces 49 formed on the arms 25 of the members 23. These arresting surfaces 15 contact with the upper portion of the front I6 of the oven in the out position, see Figure 3. thus preventing the sliding frame I3 from being pulled out too far. From the above description it will be see that 20 all that is necessary to do is to pull the front door .20 in-the down position, grasp the handle 22 and‘ pull out the oven, including the bottom 21 and the trays 6. The extent to which this struc ture can be-pulled out of the oven-is 'govemed by the position of the arresting~ surfaces 49 on the arms 25. When the sliding frame I8 is in the rear position the trays or shelves are freed from the sliding lock members 35, and. can be moved relative to each other by manual manipulation. 30 " In Figure 8 I have shown a modi?cation in which there are mounted on the» members 23 of the sliding frame I8 'shelf support frames 50 carrying on their inner surfaces grooved tracks 5| in which the‘sl'ielves'V'are adapted‘ to slide. The shelf support frames 50 are provided with lower curved surfaces 52 ‘in order to lighten the construction. This construction permits of rela tive movement of the trays 6 in the "out position” of the sliding support I8 since there is no locking of the trays 6 in any de?nite position, the trays 6 merely traveling with the shelf support frames 50. This construction presents some ' advan tages in permitting movement of the trays 6 when the sliding support I8 is pulled out, which is dif 46 ferent from the operation‘ of the construction previously described where the trays or shelves 6 can only be changed in position when the sliding support I8 is in the innermost position, and the cams 39 have raised the sliding lock‘ members 35 50 through their action against the roller-s38 carried manipulation so that a ‘particular shelf may be by the sliding lo‘ck members 35.‘ moved with relationship to any‘other particular shelf. In the ‘out p'osition'of the sliding support I8 however, all of the ‘shelves are ‘securely held in position by the sliding locking members 35 and While I have _shown_and described the preferred embodiment of ‘my invention, I wish it to be un derstood that I do not con?ne myself to the pre cise details‘ of construction herein-set"forth, by the shelves are moved in unison. way of illustration, as it is apparent tl_1_at_x'nany ' ' For the‘purpo'se of simplicity and illustration, ‘ " ~ ' ' I'have shown in 'the' drawings but one shelf 5 in changes and variations may be made therein, by those skilled in the‘artfwithou't departing from place. It is to be understood, however, that there may be a plurality of shelves, and that the pairs of opposed ‘grooved tracks 5 are each supposed the spirit of the invention, or exceeding the scope of the appended claims.‘ to support a tray or shelf ~if desired. This con struction enables the trays or shelves to be used 65 as desired, and their number varied as well as the distance between them to suit the exigencies of the cooking operation. ‘ I claim: ' , - 1.
