i. vented certainnew andi'useful Improvements in Stove-Plates; and we do hereby declare that the following is a full, clear, and exact description of our invention, reference being had to'the accompanying drawings forming a part of this specification, and tol the letters ofret'erence marked thereon, of which drawin s igure 1 is a planl of our improved plate.

Figure 6 is an en'dview of one part of plate shown in iig. 3. f i
This invention has for its object the prevention of the cracking of the plates used on stove tops, which are usually made with a long narrow neck, and are very liable to sag down and crack under the etlect of the intense heat to which they are subjected; and
It consists in making said plates in two parts,l which; parte are united to form the plate by being abutted against each other at their upper edges, and connected by a hingefjoint, having itspivot below Vthe upper plane' of the plate, so that the only effect of the heating and cooling of the plate is to cause a rising and falling of the same at the center', without 'producing any permanently injurious sagging or bending-or breaking, thuseecting therdesired result without lessening the etciency or materially increasing the cost of the plate.
To enable others skilled in the art to make and use our invention, we will proceed to describe itsA construction and operation. j
In the stove-plate shown in igs, 1, 2, and 5, A A are the two parts in which the plate is made, each being simply one-half of the ordinary plate.
'Ou the adjoining ends and lower sides of these parts A are cast the lugs B, which may be made with holes C O,\as shown in fig. 2, or with corrugated edges, as indicated in fig. 3, to allow of the passage of the flame and gases when tlie lugs project down in positions where they would interfere with the draught.
The two parts` areuuited by the plates F F, which are secured to the lugs B B by the rivets E E, which pass through the lugs B'. p i 'Ehe-length of the plates F F between the pivotsE plates F F and the holes in the E is suchthat when the upper edges of the parts A A abut against each other, as shown at- N, in iig. 2, andthe parts are atan ordinary temperature, the npper faces of the parts'A A will be in the same plane.
The plates F F may be cast with one of the lugs` B, when a single rivet E will be sufficient to unite the iwo parts of the plate, as indicated by dotted lines in g. 3.
Other modes of uniting the two parts of' the plate may be used, as, for example, in thev plate shown -iu figs. 3, 4, and `6. Y
The part H has the tongue I cast on its lower side, as shownin figs. 3 and 4, which tongue fits between the flanges L L of the part G, shown in iig. 6, where it is secured by the rivet K passing through the anges L L and the tongue I, as shown in iig. 3, the p upper adjacent edges of the parts G and N abntting against each other at N, as in the previous case. '.Lhe first construction is to be preferred, however, especially for'the long plates, as it throws much less transverse strain on theparts, and is therefore much less liable to sag down when 4heated. and subject to the strain due to the weight of the cooking utensils.
From the foregoing description o f the construction of our improvedplate, it is evident that when the plate is heated, the parts A VA will expand along their length, and as they have an end support with a hinge connection below their abutting edgesat the center, the eiiect of this heat will be to cause the plate to rise up at the center N; and in' a similar manner the cooling of' the plate will cause it to fall at the center, so that the mechanical power of the heat imparted to the plate is employed in prodncinga harmless motion of the plate at the center, instead of acting to produce an end movement of one end of the plate, which tended to increase the'transverse strain on the plate, and hence aided in sagging the plate when subjected toa load, which is often seen in theold forms of long stove-plates made in one part.
The whole plate A A can be lifted by a handle inserted in the hole M in the ordinary manner, the lower ends of theflugs B B coming to a' bearing when the plate is raise.
What we claim herein as new and of our invention, and desire to secure by Letters Patent, is'
1. A stove-plate consisting of two parts, abntting against each other at their upper edges, and united by a hinge connection having its pivot below the upper plane of the plate, substantially as and for the purpose specified. j
2. The stove-plate A A, consisting of the halves A A, provided with the lugs B B, and unitedV by the plates F F riveted or cast with one lng B, and connected by a hinge-rivet to the other lug B, substantially as and for the purpose specified.
As evidence of the foregoing, we have hereunto set our hands in the presence ofv two Witnesses this 8th day of January, 18,70.
