Weight compensator for adjustable broiler oven

An adjustable broiler stove including, a cabinet of panels forming an oven chamber, radiant heat means disposed horizontally within the top of the oven chamber, a food supporting griddle moveable within the oven chamber, elevator means comprising upper and lower arms swinging from a pair of vertically spaced supporting pivots carried by the cabinet and extending to a bracket having a pair of vertically spaced pivots carrying the griddle, the said supporting pivots being more widely spaced than the pivots at said bracket whereby said arm and pivot structure forms a trapezium configuration having a dynamic center of effort as the arms are moved, and weight compensator means comprising a tension spring extending over the said center of effort and from the bracket end of and in the plane of the upper arm and to an anchor between the vertically spaced supporting pivots thereby to have a reciprocal increase and decrease in spring pressure applied to the dynamic center of effort so that lifting action is nominally the same, and means to position the said griddle in the oven chamber and in spaced relation to said radiant heat means.
