` Claims.

This invention relates to broilers for cooking ranges and particularly to a broiler or other device which is supported on levers in such a manner as to be movable from one position to another in a horizontal plane.

In the co-pending application of H. E. Mills, Serial No. 501,373, filed September 6, 1943, now abandoned and assigned to the assignee of the present invention, a swing-out type of broiler is illustrated, described and claimed wherein the broiler swings on an arc from an upper position adjacent to the broiler burner to a lower, then an upper position when projected from the broiler compartment. While the outer and inner pol sitions were substantially of equal height so that the operator could ascertain the height of the substance being heated when within the oven, difliculty was experienced with this type of structure as the downward swinging movement of the broiler interfered with the opening of the door. This required a delay mechanism to be employed which retarded the movement of the broiler when the door was initially opened. The capacity of the broiler and the amount of its projection from the compartment were reduced by the use of the delay mechanism.

When employing the link system of the present invention a straight line movement is pro- 4lvided to thebroiler, the same as when the broiler is mounted on slides.

The link system has the advantage of eliminating the noise attending the scraping of the broiler on the slides when withdrawn from, and inserted into, the compartment thereon. f

The present invention pertains to the use of a pair of U-shaped stirrups on which the broiler is removably mounted. The stirrups are supported on their upperl ends on pivoted arms to permit the upper ends of the stirrups to move upwardly and downwardly as the broiler is moved outwardly or inwardly of the compartment. Links are mounted on pivots at the bottom of the compartment which are aligned with the bottom of the stirrups. The upper ends of the links are pivoted to the stirrup at a point above the bottom of the stirrups equal to the length of the link above its bottom pivot. The links form an isosceles triangle with the stirrups and maintain the bottom of the stirrups on a line through the pivots of the links as the bottoms of the stirrups i move toward and beyond the pivots.

While so moving, the upper ends of the stirrups are permitted to move upwardly and downwardly in View of their support on the pivoted arms at the top portion of the compartment.

Since the bottom of the stirrups moves on a horizontal plane through the iixed pivots of the links, the broiler moves outwardly and inwardly of the compartment in a horizontal plane located at a predetermined height below the broiler burner disposed in the top part of the compartment. The broiler unit preferably embodies a frame having notches in the bottom which engage the horizontal portion of the stirrups so as to be removable therefrom and retained thereon at all times against tilting. A broiler pan is selectively supported on spaced ledges provided at opposite sides of the broiler frame to be disposed at variable heights with relation to the broiler burner.

The door is spring pressed toward open and closed positions by suitable spring mechanism and an arm is provided on the inner face of the door which is interconnected to the frontmost stirrup by a link which actuates the stirrup to move the broiler unit out oi the compartment when the door is open and into the compartment when the door is closed.

Accordingly, the main objects of this invention are: to suspend a broiler in a compartment on pivoted elements which produces the movement of the broiler unit into and out of the compartment in a horizontal plane; to support a pair of stirrups on pivoted arms and attached to links which are pivoted at the bottom of the compartment to pivots on the sides of the stirrups for producing a horizontal movement to the broiler unit supported thereby; to enclose a broiler compartm'ent with a door having a spring thereon which retains the door in open and closed position and which is interconnected to a broiler suspension mechanism by a link which moves the broiler pan out of the compartment when the door is open and into the compartment when thev door is moved to closed position; and in general to provide a broiler unit which is moved into and out of the broiler Acompartment in a horizontal plane by link mechanism actuated when the door is moved into closed and open positions,

all of which is simple in construction, positive in operation, and economical of manufacture.

Other objects and features of novelty of this invention will be specifically pointed out or will become apparent when referring, for a better understanding of the invention, to the following description taken in conjunction with the accompanying drawings, wherein Figure l is a perspective view of a cooking stove having a broiler therein embodying features oi this invention;

Fig. 2 is an enlarged view, in front elevation, of the broiler compartment and movable broiler therein embodying features of this invention;

Fig. 3 is a broken sectional view of the side of the broiler compartment illustrated in Fig. 2, with the door in closed position;

Fig. 4 is a view of the structure illustrated in Fig. 3, with the compartment door in open position, and

Fig. 5 is a plan view of the right-hand side of the compartment illustrated in Fig. 4.

In Fig. l a stove I is illustrated, having an oven compartment enclosed by a door I I, a broiler compartment enclosed by a door I2, and two drawer compartments enclosed by the front drawer panels I3. The broiler compartment ifi embodies side walls I5, a top wall I6, and a bottom wall Il. Angles braces I8 are provided on the side walls I to provide additional strength for the support of the broiler compartment within the stove. A pair of U-shaped stirrups i 9 have the ends of the upwardly projecting arms 2i pivoted at 20 to the ends of links 22 which are pivotally secured on studs 23 to the sides I5 of the broiler near the top of the compartment. Links 24 have their lower ends mounted on pivots 25 which are secured to the side walls I5 of the compartment and to the reinforcing channel elements I8. The top ends of the links 24 are pivotally secured on the studs 26 which project from the upwardly extending arms 2I of the stirrups. The length of the links 24 between the pivots 25 and the studs 25 is .equal to the length of the arms 2I from the stud 25 to the horizontal portion 21 of the stirrup. This forms an isosceles triangle between the portion of the arms 2l and the links 2li at substantially all positions of the stirrups so that the portions 2 of the stirrups will be maintained in a horizontal plane in all positions in which the stirrups are moved. This is made possible by the support of the upper ends of the arms 2i on the pivoted links 22 which permit the ends to oscillate about the stud 23 as the horizontal portion 2! of the stirrup moves in the horizontal plane.

The horizontal portion ZI of the stirrup is retained in the horizontal plane by the links 24 which, as pointed out herein-above, is in isosceles triangular relation with the bottom portion of the arms 2| in all positions of the stirrups except, of course, that when the link and arm are in the same vertical plane. One or more cross links 28 may be attached to the studs 26 of the stirrups to have both of the stirrups positively moved when the door is opened. The door is of the conventional type having a spring Sil associated therewith for retaining the door in both open and closed positions. A fixed arm 3I projects from the inner face 32 of the door, the outer end of which pivotally supports one end of a link 33 the opposite end of which is pivoted to a projecting stud 26 on the front stirrup I9.

The broiler unit embodies a frame 3&3 which is herein illustrated as a stamping having a back wall 35 and side Walls 36 which are unsupported at the front end. The rear bottom edges of the side Walls 33 contain angularly disposed slots 31 which receive the horizontal portion 2 of the rear stirrup in such manner as to prevent the frame from tilting upwardly therefrom. The front portion of the side walls 35 is provided with an elongated notch 38 which receives the horizontal portion 2l of the front stirrup I9 after the rear portion is hooked over the rear stirrup. The notch 38 is preferably provided with a flange 39 at the top for preventing wear. The inner face of the side walls 35 is provided with horizontally disposed channel portions 4i which receive the broiler pan and tray 42 which are similar in construction to the broiler pan and tray disclosed in the above-mentioned co-pending application. The broiler pan and tray may be slid forward on the channel portions 4I and are positioned at various heights within the frame 34 thereby. The construction of the operating mechanism of the broiler is such that the weight of the frame, broiler, pan and tray and the food and utensil supported thereon tends to maintain the broiler in any position of adjustment. When the door is moved to open position, the arm 3i thereof moves the link 33 to move the stirrups frontwardly to thereby move the frame 34 and the pan and tray 42 on a horizontal plane out through the compartment opening 44. When the door is moved to closed position, the link reverses the movement of the stirrups to move them from the position illustrated in Fig. 4 to that illustrated in Fig. 3 when the door is maintained in closed position -by the balancing spring 30.

A burner 45 of conventional form is mounted in any suitable manner within the upper part of the compartment and is herein illustrated as being mounted on a rod 46. The ends of the rods are retained in the U-shaped brackets 4l' and 48 on the lrear and front walls, respectively, of the compartmentbvThe medial portion of the rod eX- tends through apertures in bosses 49 projecting upwardly from the top surface of the burner. The mixing chamber 5I of the burner extends through an laperture in one of the side walls I5 and is connected to a suitable source of gas supply and controlled in the conventional manner. While a gas burner 45 is herein illustrated, it is to be understood that an electric heating unit may be substituted therefor.
