SPEGIFIGATION forming part of Letters Patent No. 516,373, dated March 13, 1894. Application filed September 25, 1893. Serial No. 486,492. (No model.)

thereon,which form a part of this specification.

The object of this invention is to prevent the. center lid or cover of a stove or range from sagging when subjected to high heat and the weight of the covers supported by said centenand to thus maintain a more leveland even top surface on said range or stove and closer joints between the parts.

The invention consists in the improved cover or lid and in the arrangements and combinations of parts, all substantially as will be hereinafter set forth and finally embraced in the clauses of the claim.

Referring to the accompanying drawings in which like letters indicate corresponding parts in each of the figures, Figure 1 is a plan of a center lid or cover, and Figs. 2 and 3, sections of the same on lines wand y, respectively, the said lid being shown in each view in reverse position.

In said drawings, a indicates the center lid or cover having arms a, a, a which project from the central part to engage the body of the stove and be supported thereby. The sides of said arms are curved as at a a a which curves supplement similar curves on adjacent parts of the stove or range and are adapted to complete the formation of round pot-holes in the ordinary way. Said sides are provided with projecting ribs, a, to strengthen 'the lid and provide suitable supports for the round lidswhich close said pot-holes. These parts are of ordinary construction and may be modified at pleasure to suit varying conditions. v

On the under side of the lid or cover, a, are raised bridges b, b, I), cast in-tegrally on the lid and lying longitudinally at the centers of the arms. Said bridges integrally join the center partof said lid with the outer ends of the arms and are arched over the centers of the arms so as to form open spaces, b at said centers. The inner upturned ends of the bridges come togetheratthe center of the lid on a plane very close to that of the lid, there being no intersecting of arches orintegral connections of or between the same back from the extremities tending to act against uplifting pressure due to expansion. On the contrary the expansion arches are independent "of one another excepting whcrethey unite integrally with one another and with the body of the lid atthe plane of said lid.

When the lids or covers are heated by the fire of the stove in ordinary service, and the 1 same are subjected also to the weight of the pots, 850., upon said stove, the expansion of the metal of the bridges produces an upward pressure at the center of the lid, which serves to resist the tendency to sag at that point. This upward pressu re at the center is rendered positive because of the opposition pressures of the extremities of the expansion bridges acting together on the lid. The central part of the said lid-center is thus held level, holding the round lids properly in place so that no-open joints are formed and escape of heat therethrough allowed. 1

Where the center lid is provided with three arms a, a, a as shown in Fig. 1, I arrange the expansion bridges so that the bridges b, 1), form the same obtuse angle on opposite sides of the bridge, I), and thus the pressure of said bridges, I), bear equally against the end of the bridge, I), from opposite sides, thus preventing a warping of the lid.

' I am aware that the construction shown may be modified without departing from the invention.

Having thus .described the invention, what I claim as new is- 1. The improved stove lid herein described having on the under side thereof castbridges, the inner upwardly turned ends of which integrally connect one with the other and with the body of the lid at the center of the said body, substantially as set forth.
