UNITED STATES PATENT OFFICE.
WILLIAM B. EVANS, 0F PHILADELPHIA, PENNSYLVANIA, ASSIGNOR 0F ONE-HALF TO ERNESTH. GERHARDT, OF PHILADELPHIA, PENNSYLVANIA.
LID FOR STOVES, RANGES, AND THELIKE.
To all whom it may concern:
Be it known that I, WVILLIAM BpEvans, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Lids for Stoves, Ranges, and the like, of which the following is a specification.
This invention has relation to lids for stoves, ranges and the like and has for its object the provision of a lid of novel character which will promote perfect combustion of gases generated by the burning fuel, a large proportion of which, under the ordinary and usual conditions, passes unconsumed to the stove pipe or chimney.
In carrying my invention into effect I provide a stove lid of novel construction by means of which preheated air is introduced into the fire box of the stove or range above the fire and there mingling with the unconsumed gases, provides oxygen for the promotion of combustion and effects a saving of fuel by the increased heat derived from a given amount of fuel.
My invention consists in the novel construction, combination and arrangement of parts hereinafter described and claimed.
I have illustrated my invention in the accompanying drawing wherein Figure 1 is a plan view of a portion of the top of a stove or range, and of my improved lid in position thereon. Fig. 2 is a plan view of a one-piece hollow cylindrical casting constituting a part of the lid shown in Fig. 1, but detached therefrom for illustration of its internal construction. Fig. 3 is a vertical sectional view on the line w-m of Fig. 1.
My improved lid is adapted and intended to take the place of one of the ordinary lids of the stove or range to which it is applied and consequently is of circular contour and of such diameter as to fit neatly in one of the lid holes of the stove top and is composed of an upper flat plate, 1, which is of a diameter corresponding to the greatest diameter of the hole, 2, in the top, 3, of the stove. The hole is of the usual character, being formed with the circular shoulder or ledge, 4, to sustain the lid and the edge portion of the plate, 1 rests on this shoulder 41 so as to prevent the lid from dropping into the stove.
A one-piece hollow, cylindrical casting 5,
Specification of Letters Patent.
Application filed December 10, 1912.

Serial No. 735,977.
is allixed on the bottom of plate 1, being secured to the plate by bolts (5, passing through suitable holes in the plate 1 and the bottom of the casting and nuts 7 and between the bottom of the plate, 1, and the upper surface of the casting, 5, a circular sheet of asbestos 5 is arranged and constitutes a packing to prevent the escape of air between the plate and the casting.
The interior of the casting 5, as best shown in Fig. 2, divided into two series of parallel fines or passages, 7, by vertical integral partitions, S, the fines or passages on one side of the center of the casting communicating with one another successively at alternate ends and the lines or passages at the other side of the center communicating with one another in the like manner, and the vertical outer wall of the casting is provided with a plurality of small holes, f), through which the air after passing through flues or passages will flow into the interior of the stove or range, the holes, 9, being arranged as shown below the level of the bottom of the stove top.
At one side of the casting a wall or partition 10, is formed that is not in communication with the fines or passages 7, and forms, in connection with a square hole, 11, in the plate, 1, a lifter-holc for the lid lifter commonly employed to lift stove lids of the ordinary character.
The plate, 1, is formed with a shallow groove, 19., on its upper surface and in this groove is arranged a fiat strip, 13, having an upset rib 14, at its center, the strip, 13, being held in position on the plate, 1, by rivets, 15, which pass through slots, 16, in the strip, 13, the slots permitting a limited movement of the strip longitudinally, which movement is readily effected by pushing against or tapping the rib, 14:, with any convenient instrument, such as the ordinary lid lifter or the poker of the stove.
The plate, 1, is formed with the holes, 17, which extend through the plate and open into the two outermost flues or passages, 7 of the casting, 5, and the strip, 13, is formed with two holes, 18, corresponding in size and distance apart to the holes 17, the latter registering with holes, 18, at one position of the strip, 13, while at other positions of the plate the holes, 17, will be partly closed, as shown in Fig. 1, by the body of strip 13. The normal position of the strip 13 when the fire is burn ing at full force is such that the holes, 18, will exactly register with the holes, 17 so as to make available the fullest inlet capacity of the holes, 17 but when the fire is damped down or slacked down as, for instance where it-is left to burn slowly all night, then the strip is pushed lengthwise so as to bring the holes, 17, and 18, partly out of full register, thereby limiting the inlet capacity of the holes, 17
The top of the plate 1 is formed with a number of concentrically disposed arcshaped discontinuous ribs 19 preferably so arranged as to break joints at the spaces between ribs and afford a somewhat tortuous assage for air from the outer edges of the plate, 1, to the holes, 17, when a pan, kettle or other vessel is laid on the plate 1.
Operation: The lid above described being placed in proper position on the stove with the holes 9 toward the outgoing draft of the fire, which position is indicated by a small arrow, 20, in the top of the plate, 1, which arrow should be pointed toward the smoke pipe; the draft of the stove will create a suction that will cause air from above the plate, 1, already partly heated by c0ntact with this plate, to be drawn through the holes, 17, and into the casting, 5, and, passing through the flues or passages, 7 in the course indicated by the long dotted arrows y, the air will be further and highly heated and finally flow out through the holes 9 and mingle with the gases e1nanating from the fire and promote perfect combustion of these gases with the obvious effect of greatly increasing the heat for a given amount of fuel consumed. l/Vhen the fire is slacked down or dampened down, the holes 17 should be partly closed by sliding the strip 13 lengthwise, as I found that mit gas to escape into the room. If the fire is very low and the dampers all closed, the holes, 17, may be entirely closed to entirely avoid any possible chance of the gas taking the Wrong course through the lid and escaping into the room.
I claim:
1. In a stove lid the combination of a plate having curved, overlapping, discontinuous ribs on its upper surface anda vertical hole on each side of its center, with a slidable damper having holes registering with the vertical holes in the plate, a hollow cylindrical casting secured to the bottom of said plate, said casting having a central rib dividing the casting into two compartments and other ribs forming tortuous passages in said compartment-s, the vertical holes in the plate leading each into one of said compartments and the casting having holes for the egress of air in its outer Wall.
2. A stove lid consisting of a plate having overlapping discontinuous ribs on its upper surface and carrying a hollow casting on its lower surface constituting an air chamber, said plate having a vertical hole leading to said air chamber, and said ribs being located at opposite sides of said vertical hole, said casting having a hole for egress of air below said plate.
In testimony whereof. I have affixed my signature in presence of two witnesses. 4
