4 Claims.

This invention relates to improvements in cooking stoves.

One object of the invention is to provide a stove which will require a minimum amount of space, this object contemplating a construction in which the burners or heating elements and the supporting structure therefor are movable as a unit into the stove when not in use thereby increasing the available space in the vicinity of the stove.

A further object is to provide a stove in which the burners or heating elements, oven, broiler and auxiliary compartments are incorporated in a cabinet-like structure of pleasing appearance.

A still further object is to provide a construction in which the burners or heating elements may be utilized when in their extended position as well as when they are moved to a retracted position within the stove.

A still further object is to provide a novel mechanism for moving the burners or heating elements to and from their extended position.

A still further object is to provide a novel design and arrangement of the parts of the stove, whereby simplicity and economy in construction are obtained.

The invention is illustrated in the accompanying drawings in which:

Figure l is a front elevation of a stove embodying features of the invention.

Figure 2 is a side elevation of the stove.

Figure 3 is a top view of the stove.

Figure 4 is a fragmentaryl horizontal section and is taken along line 4 4 of Figure 2.

Figure 5 is a vertical section taken along line 5-5 of Figure 1, the burners or heating elements being shown in their extended position.

Figure 6 is a fragmentary sectional view and is taken along line 6-6 of Figure 1, the burners or heating elements being shown midway between their extended and retracted positions.

Figure '7 is a vertical section taken along line 'I-I of Figure 5, the burners or heating elements being shown in their retracted position.

The stove, as illustrated, includes a cabinetlike body III which is divided into a vertical series of compartments II, I2, I3 and I4, the compartments II and I2 including doors I5 and I6, respectively, and the compartments I2 and I3 be.- ing separated by a horizontal wall I3a. The said doors are provided with handlesA II and at their lower sides are pivotally mounted in the stove body so that when open they occupy a substantially horizontal position. The compartment II is adapted to provide an oven While the upper part r of the compartment I2 provides a broiler I8, a

1934, Serial No. 717,316

burner IB being associated with the oven and broiler in a conventional manner and being connected to a suitable gas supply pipe 20. The compartment I2 preferably includes side walls I 2a (Figures 4 and 7) which are suitably spaced from the side walls of the cabinet body, the broiler section I8 of the said compartment having a drawer 2| which is slidably supported between the side walls I2a upon angle members 22 and being provided with a suitable handle 2 la. The drawer 2| may be pulled out to enable access. to the broiler tray (not shown) after the door I6 is opened. The side walls of the broiler section I3 may, as illustrated, be provided with opposed series of ledges 23 for adjustably supporting the broiler tray in the desired relation with respect to the burner I9. The compartments I3 and I4 are auxiliary with respect to the compartments II and I2 and may be dispensed with if desired. They are available for the storage of kitchen utensils and such other articles as may be desired. In order to render the contents of the compartments I3 and I4 more accessible they include

drawers

24 and 25, the former having low side walls so as to enable access to it at times when the door I6 may be open.

The service burners 26 of the stove are incorporated in a carriage 21 which is movably suppo-rted upon the wall I3a by rollers 21a. The carriage, as illustrated, including a top 28 formed in a conventional manner with openings over the burners and having suitable plates 29 for closing said openings. The carriage is normally located in the compartment I2 beneath the broiler. When in this position the door I6 of the said compartment may be closed and the service burners will be concealed from view.

In accordance with the invention the carriage 2l is movable to an extended position in which it lies wholly outside the compartment I2, the door I6 serving to support the carriage in its extended position as best shown in Figure 5. In this connection it will be noted that when the carriage is in its extended position the top 28 of the carriage is available for use similarly to the top of a cooking stove of conventional construction. When the carriage is in the compartment I2 the space occupied by the carriage when extended is` available ior other purposes. It will be apparent, therefore, that the stove has the advantage that additional space is provided in the vicinity of the stove when the service burners are not in use. Hence the stove is particularly desirable for use as an apartment stove or in other environments in which the space available'ils limited.

Means isprovidedwhereby the carriage 21 is moved automatically to and from its extended position as the door I6 is opened and closed. In other words, assuming that the carriage 21 is in its retracted position and the door I6 is closed, the carriage may be moved to its fully extended position by opening the said door and when extended may be moved to its retracted position within the compartment I2 by closing the door. To this end bars 30 are pivotally connected at one end to pins 3| which are carried at opposite sides and at the forward end of the carriage 21. At their opposite ends the said bars are connected to the lower ends of companion bars 32 to provide cooperating pairs of toggle joints which are located at the opposite sides of the carriage, the upper ends of the arms 32 being pivotally connected to the adjacent side walls of the cabinet body by pins 33.

In order to operate the toggle bars to move the carriage 21 into and out of the compartment I2 in themanner described, arms 34 are carried by the opposite sides of the door I6. The said arms extend rearwardly adjacent the side walls of the cabinet and when the door I6 is closed (see Figure 2) parts of the arms lie along opposite sides of the compartment I2 between the side walls I2a. of the said compartment and the side Walls of the cabinet body while the lower parts or free ends. 35 of the said arms lie along opposite sides of the compartment I3 between the sides of the drawer 24 and the side walls of the cabinet body. When in this position the forward or upper edges 36 of the free ends of the arms 34 lie in a substantially horizontal plane in the vicinity of the wall I3a. It will be apparentthat as the door I6 is opened fully, that is to say to a position in which it is substantially horizontal, the free ends 35 of the arms 34 move to an upright position (see Figure 5) in which the forward edges 36 of the said ends are substantially vertical. As the forward edges 36 of the free ends of the arms 34 reach a vertical position they engage suitable stops 31 formed or provided upon in the cabinet body. The stops 31 arrest further outward movement of the free ends of the arms 34 and serve to support the door I6 in its open or horizontal position.

The movement of the arms 34 is utilized to operate the toggle links. To this end the free ends of the arms are formed with curved slots 38, each of the said slots providing

cam surfaces

39 and 46. The entrances to the slots 38 are so formed that as the free ends of the arms 34 move upwardly and outwardly, during the nal part of the opening movement of the door I6, rollers 4I which are mounted upon the toggle bars 32 enter the slots (see the dotted line position of the arms 34 in Figure 5). During the final part of the opening movement of the door, that is to say the movement from the dotted line position shown in Figure 5 to the full line position, the rollers 4I move from the entrances of the slots 38 to positions in the Vicinity of the closed ends thereof. The movement of the rollers 4I from the entrances to the closed ends of the slots 38 is effected by the action of the cam surfaces 39, these surfaces engaging the rollers during the final part of the opening movement of the door. The bodily movement of the rollers 4I is transmitted through the toggle bars 3U and 32 to the carriage 21, the said bars and the cam surfaces 39 being so designed that as the forward edges 36 of the free ends of the arms 34 engage the stops 31 the carriage 21 reaches its fully extended position.

As noted heretofore, the cam surfaces 39 of the arms 34 come into play only during the final part of the opening movement of the door. In other Words, the carriage 21 remains stationary in the compartment I2 during the first part of the opening movement of the door. During the final part of the opening movement of the door the carriage rolls out of the compartment I2 upon the back of the door. It will be apparent, therefore, that as the carriage 21 starts to" roll out of the compartment I2 and upon the door I6 the latter is inclined to some extent. The toggle operating mechanism, however, is so designed that the carriage 21 is caused to roll up the inclined surface of the door, the angle of inclination of the latter decreasing as the carriage continues to move outwardly. Preferably the carriage reaches the limit of its outward movement as the door I6 reaches a horizontal position.

The carriage 21 may be returned to the compartment I2 by closing the door I6. During the initial part of the closing movement of the said door the cam surfaces 40 on the arms 34 engage the rollers 4I (see Figure 6) and force them rearwardly and upwardly. As the door closes the outer end of the carriage 21 is lifted as shown, thereby aiding movement of the carriage into the compartment. The rollers 4I follow the cam surfaces 40 until they reach the dotted line position shown in Figure 5. This movement of the rollers is transmitted through the toggle bars 36 and 32 to the carriage 21, the said carriage reaching the rearward limit of its range of movement within the compartment I2 as the rollers reach the said dotted line position. Thereafter, during the final part of the closing movement of the door the cam surfaces 4I) move away from the rollers 4I and the free ends of the arms 34 move toward the dotted line position shown in F'igurev 2. As the carriage reaches the limit of its movement into the compartment I2 it comes to rest against a stop 42. The said stop cooperates with guide elements 43 formed or provided upon the side walls I2a of the compartment to hold the carriage in such a position that the rollers 4I will enter the slots 38 when the door I6 is opened. The side walls I2a are cut away as at 44 (Figure 6) to accommodate the pins 3I by which the toggle bars 39 are connected to the carriage, the said bars, as illustrated, being located between the side walls I2a of the compartment I2 and the side walls of the cabinet body. The slots 44 permit the carriage to move into the compartment I2 so that it abuts the stop 42 as described.

The service burners 26 are connected to a header 45 (at the forward end of the carriage 21) to which gas may be supplied through a conduit 46, the supply of gas to they burners being controlled by suitable valves 26a. The said conduit communicates with a pipe section 41 which depends from and which is rigidly secured to the rear end of the carriage, the said pipe section communicating with a branch 48 of the gas supply pipe 20 through a pair of pipe sections 49. The pipe sections 49 are suitably connected together and to the pipe sections 41 and 48 so that as the carriage is moved to its extended position they open or expand to the position shown in Figure 5. When the carriage is moved to its position Within the compartment I2 the joined end-s of the pipe sections 49 move upwardly as the said sections collapse upon one another (see dotted line position in Figure 5). It will be apparent, therefore, that by connecting the service burners to the main gas pipe in the manner described, gas will be available in both the extended and retracted positions of the carriage. It is to be noted that in the full line position of the pipe sections 49 (Figure 5) the said sections extend upwardly toward their connecting ends. This insures collapsing of the sections in the manner described when the carriage is moved into the compartment I2. In this connection it is to be understood that the plates 29 may, if this character of heating element is desired, be heated by electric resistance elements instead of by gas.

As illustrated, and preferred, the compartment I2 is so designed that there will be adequate space between the top 28 of the carriage and the bottom of the broiler to accommodate the cooking utensils that are normally employed in connection with the stove. This has the advantage that the contents of the utensils may be prevented from cooling rapidly, after having been cooked to the desired extent, by moving the carriage within the compartment I2 and closing the door I6.

When using the broiler the door I6 may be opened, without withdrawing the carriage 21, to the extent necessary to enable. access to the broiler drawer 2|. The latter can then be pulled out through the opening of the door I6 to the extent necessary to gain access to the broiler tray. The front panel 5I) of the broiler drawer 2| is preferably formed with suitable openings 5I to permit the escape of the. cooking vapors, it being understood in this connection that the door I6 may, as is customary with stoves of conventional construction, be left partially open during use of the broiler.
