and also is adjustable vertically relative to the.

broiling compartment burner means of said stove or other heat-producing means, the predominant object of the invention being to provide anim proved broiler of the class described which, because of improved details of constructionthereof, functions with much more efliciency than did. other similar broilers heretofore known.

The improved broiler disclosed herein is an improvement on the adjustable extension broiler covered by United States Patent No. 1,852,087, granted to me on April 5, 1932 The features of improvement which are present in the structure disclosed herein and are not found in my previously patented broiler are the improved means for securing the elevating frame of the improved device in different elevated positions; the improved means for providing for free sliding movement of the sliding frame relative to the stationary frame of the structure; and the improved manner of insuring alined movement of the sliding frame with respect to the stationaryframe.

The improved features referred to above are described in detail in' the following specification,

and are illustrated in the drawing, in which Fig. 1 is a fragmentary front elevation of a stove having the improved adjustable extension broiler associated therewith. I i

In the drawing, wherein is shown for the purpose oftillustration', merely,'one embodiment of the invention, A designates a stove which is provided with a broiling compartment B. The stove A includesa'suitable door 0, which acts as 'a closure element for the'broiling compartment B as well as for-an oven (not shown) located above said broiling compartment.

Arranged within the lower portion of the broiling compartment 3 of the stove A is my improved adjustable extension broiler D, which includes a stationary frame I, a sliding frame 2, and an elevating frame '3: Thestationary frame I is rectangular in shape and preferably, though not necessarily, is made up of angle bar members which are welded'or otherwise secured together in their assembled form to produce the frame. The opposite side members of the stationary frame are provided with pairs 'ofinwardly extended lugs' l, and. suitabl'e'fastening devices 5 are extended through apertures formed through these lugs and through openings formed in thebottom wall"ofithebroiling compartment for the purpose of fixedly securing thestationary frame in place.- The stationary frame'includes also a bar 6 which extends'longitudinally of said stationary frame at the approximate transverse center of the frame, and this bar ,6 is provided with a slot I which isextendedlongitudinally thereof, as shownin Fig. 3.

Arranged immediately above the stationary frame! of the broiler structure is the sliding frame 2, which likewise is rectangular in shape and is formed of angle .bar members welded or otherwise secured together ,in their assembled form. The angle bar'members of the stationary framel are arranged so that legs, thereof are extended horizontally and downwardly, while the angle bar-members of the sliding frame 2 are arranged so thatlegs thereof are extended horizontally and upwardly. The horizontal legs of the angle bar members of the frames l and 2 are spaced apart from each other vertically, and interposed betweensaid horizontal legs of said frames are anti-friction devices 8. The antifriction devices may be of any suitable type, and preferablyqpairs of said devices are arranged between the side angle bar members of the frames 1. and 2, as indicated by dotted lines in Fig. 3. By preference the two anti-friction devices 8 located-adjacent to theforward ends of the frames l and 2 are secured to the stationary frame I, while the twoanti-friction devices adjacent to 'to-the sliding frame2 (Fig. 5).

which extends longitudinally of said frame invertically aiined parallelism relative to the bar 6 of the stationary frame I. The bar 9 is provid ed with a pair of apertures through which bolts or like elements I pass, these bolts passing also through the slot I formed in the bar 6 of-the stationary frame I The bolts ID are providedwith heads and nuts, and said nuts are positioned on the .bolts so that said bolts are loose relative to the bars 6 and 9. Thus when the sliding frame 2 is. mo'ved'forwardly or rearwardly of the stationary frame I, the bolts 'ID move longitudinally of the slot I in the bar I5, whereby 'the sliding frame fi is guided in its movement with. respect tothe stationary frame. As anadditional means for guiding the movement of the sliding frame 2, I provide a yoke II (Figs. 2 and 6) which issecured by weldingor otherwise-to the bar 6 of the stationary frame and embraces: the bar 9 of the sliding frame. During movement of the sliding frame 2 thebar 9 thereof moves through the yoke II to insure valined movement of the sliding 4 frame. In addition to performing the function of guiding the movement of the sliding frame 2, the bolts I0 and yoke II prevent upward movement of thesliding frame with'respect to the stationary frame.

Theelevating frame 3 is rectangular in shape andis formed of angle bar members which are Welded or otherwise securedtogether in their assembledform. The elevating frame'is of approximately the same width as the stationary and sliding frames, but is of less length than the latter frames, as shown :most clearly in Figs. 2

and 3 of the drawing. The angle barmembers of the elevating frame 3 are arranged so as'to provide horizontally and verticallydisposed leg 1 portions, the horizontally disposedleg portions being at the top of the frame. In order to movably secure the elevating frame '3 to the'sliding frame 2, I employ arms I2, four of such arms being illustrated with a pair thereof at each side of the associated frames 2 and '3. 'Each arm I 2 is pivotally secured to a longitudinally extended side angle bar member of the sliding frame 2 and to an adjacently arranged, longitudinally ex tended side'angle bar member of the elevating frame 3. The arms are mountedso as to be con tinuallyin a state of parallelism, and with the arms located opposite each other disposed in'the same plane. It will be'seen, therefore, that in any position of the elevating frame 3 relative to the sliding frame 2 the planes of these two frames will be parallel, and that when the plane of the stationary frame I is horizontal, i which is the'case in practice, the sliding frame 2 and the elevating frame 3 will always be in horizontal planes. At the forward end of the elevating frame 3 a suitable handle "I3 is fixed thereto to facilitate imparting sliding movement of the sliding frame and elevating movement to the elevating frame.

The means for maintaining the elevating frame 3 in various elevated positions to which it has been moved comprises opposed racks I4; which are secured to the opposite side angle bar members of the sliding-frame 2. The means referred to includes also a bar I5 which extends transversely of the elevating frame 3 at a point immediately adjacent to the forward end thereof. The bar I5 at its opposite ends is supported for rotary motion by the opposite side angle bar members of the elevating frame 3, and fixed to said bar I 5 is a pair of arms I6. The arms I6 extend rearwardly of the bar I5, and the rear end portions of said arms I6 are supported by teeth of the racks It. The bar IE'has fixed to it at its approximate center an operating member I], which is curved downwardly and forwardly and upwardly, and is provided with a portion I'I that is disposed immediately adjacent to the handle I3 of the elevating frame 3.

It will be observed that when the sliding frame 2 has been moved to its outermost position and the elevating frame 3 has likewise been moved to its outermost position (note broken line positions of these frames on Fig. 2), said elevating frame is disposed in aposition in front of the plane of the front wall of the associated stove A. The elevating frame is maintained in this forwardly proje cted position by the forward arms I2 contacting with stop elements I 8 formed on the sliding frame 2. It will be noted also that the distance between the planes of the elevating frame and the sliding frameis varied when the arms I2 are rotated on their pivot points, and thatrthe elevating frame may be moved from its lowermost elevation, where the elevating frame rests upon the sliding frame (the rearmost position of theelevating frame relative to the sliding frame), to its highest elevation, where the arms I2 are in vertical planes. Because of the reduced length of the elevating frame-3, said'elevating frame maybe adjusted to different elevations within the broiling compartment of the stove A without any portion of said elevating frame being extended beyond the frontwall of the broiling compartment. It is possible thereforato adjust the elevating "frame so that the food being broiled is positioned the proper distance from the burner means B of the broilingcompartment, and to close the door C of the broiling compartment without interference from the adjusted elevating frame.

' When'the elevating frame is being adjusted to different elevated positions, the handle I3 is grasped and drawn upwardly and forwardly. This rotates the arms I2 .on their pivots and also causes the free rearmost end portions of the arms I6 to slide over the teeth of the racks I4. When the desired elevation of the elevating frame has beenreached, the handle is released and the free rearmost ends of the arms I6 will engage teeth of the racks I4 and maintain the elevating frame, in the position to which it has been adjusted (Fig. 4). -When it is desired to release the elevating frame from a position to whichit has been adjusted, the portion ll of the operating device V I1 is depressed by moving a thumb or finger thereagainst, whereby the free. rearmost end portions of the arms I6'will be elevated to,

disengage same from the teeth of the racks I 4.

When in the use of the improved broiler it is desired to position an article to be broiled in the broiling compartment of the stove, the broiling compartment door is opened and the handle I3 is drawn 'outwardly'to move thesliding frame to its forwardly projected position. The handle I3 is th n draw-n forwardly and upwardly to elevate the elevating frame in the manner already explained. When the article has been positioned in the broilerpan D, the elevating frame is adjusted to the desired elevation, after which the sliding frame and the adjusted elevating frame are moved inwardly into the broiling compartment of the stove and the door of said broiling compartment is closed.

By employing means for securing the elevating frame in different positions which operate at opposite sides of the broiler, the elevating frame is evenly supported throughout. Also, the antifriction devices 8 between the sliding frame 2 and the stationary frame I eliminate all binding between these frames and therefore render.movement of the sliding frame exceptionally easy. Finally, the use of the yoke ll insures perfectly alined movement of the sliding frame relative to the stationary frame.
