It is one object of the invention to provide a barbecue structure in which the grate may be readily adjusted as to the heating medium without material discomfort to the operator; in which a portion of the grate may be used to support a warming plate if it is so desired, with the said plate permanently associated therewith; in which the parts are so formed and assembled as to provide a strong, substantial and durable device that will be economical to manufacture, and highly efficient in its practical application.

In the drawings:

Figure l is a perspective illustration of the structure embodying my invention.

Figure 2 is a plan view of the grate on line 2-4 of Figure 1, with parts broken away.

Figure 3 is a perspective illustration of one of the grate hangers.

Figure 4 is a detail section on line 4-- l of Figure 1.

Figure 5 is a section on 55 of Figure 1.

Figure 6 is a perspective view of one of the corners of the grate supporting frame.

Figure '7 is a perspective View of a cable connec- 0 tion to the grate.

Figure 8 is a perspective View of the cable con nection to the adjusting lever.

Figure 9 is a perspective View of a portion of the adjusting lever showing the joint at which it may be folded.

Where no other means of attachment is shown it. may be assumed that the parts are secured to gether by spot welding.

The frame forming the base and support for the grate structure may be mounted upon any kind of a pit, a brick pit here being indicated in dotted lines at I.

The frame 2 is rectangular in form and is made of four lengths of angle iron 3 secured at their corners by triangular corner pieces l.

Upon each end of the oblong rectangular frame 2 is mounted a bracket 5 having vertical portion 6 spaced back from the inner edge of the frame as shown.

At 1 is shown a U bar in cross section and bent into the form of an inverted U with its two ends resting upon the top of the frame 2 and secured in a vertical position to the inner faces of the two brackets 5. Punched outwardly in the end portions of bar 1 are downwardly inclined fingers 8 to form stops for the purpose hereinafter described. A pulley 9 is journaled in one end of bar 1 to project through an opening l0 therein, and a similar pulley H is journaled in a bracket l2 in the other end of the bar as shown.

The grate i3 is formed of two pieces of U bar, each piece having its end portions turned at right angles thereto to form one-half of the end portions of the grate, the flanges of the bar being turned outwardly. The opposing ends of the bars abut each other and are secured by a plate 14 which is formed as at l5 to seat in the said bars along its lower edge.

Extending upwardly from each end plate is is a hanger portion it provided with a hook as H, and on the outer side of each portion iii is mounted a strap as it having an outwardly turned lip as l9 to form a stop engageable with the frame 2 to limit the downward movement of the grate.

Mounted upon one corner of the frame 2 is an upstanding bracket 29 in which is pivotally mounted a lever 28. The lever is formed of two parts that are pivotally connected at 22. The outer part 23 is provided with a handle 24 and a finger 25 turned on its pivoted end to engage a notch 29 on the adjacent end of the other portion whereby the part 23 may be turned back when not in use and yet will be held rigidly in alignment with the first part when fully extended and a downward pressure is applied thereto. An intermediate portion of the lever is bent at an angle thereto as at 2i to engage fingers 8 as desired. A cable 28 is secured to an eye 29 on lever 2!, one portion passing over the two pulleys to engage the hook i'l on one hanger i9, and the other passingover one pulley to engage the hook ii on the other hanger Iii. The cable fastenings are shown at 3B.

The grate l3 includes the spaced rods 3| upon which the food is placed, and each end of each rod is passed through a hole 32 in the side bar and then upset as indicated at 33, thereby allowing the rod to expand and contract lengthwise and preventing its buckling in the center under wide changes of temperature.

At 34 is shown a plate hingedly mounted as at 35 on one end of the grate and in a position to rest upon the adjacent rods 3! when it is desired to use the plate for cooking purposes or for keeping food warm. When its use is not desired it may be swung into a substantially vertical position out of the way, leaving all of the rods 3| available for barbecue purposes.

The parts is slide in the guide formed by the flanges of bar i and effectually maintain the grate in a horizontal position and prevent swinging of the same when in use.

It is to be understood, of course, that while I have herein shown and described but one specific embodiment of the invention, changes in form,

the plane of the frame, guide means inserted between the grate and bracket end portions, a lever fulcrumed on one end of the frame, sheaves journaled on opposite ends of the bracket, cable means leading from the lever over the sheaves to opposite ends of the grate, and stop means associated with the bracket to engage the lever and thereby support the grate in a desired position relative to the frame.

CHARLES B. POLHEMUS.
