FLAME TESTER Fil ed May 7, 194a Patented May 4, 1948 FLAME TESTER William F. Wagner, North Braddock, Pa., assignor of fifty per cent to Clarence R. Wagner and fifty per cent to Harry L. Wagner, both of North Braddock, Pa.

Application May 7, 1946, Serial No. 667,952

4 Claims. (01. 73190) My present invention relates to an improved flame tester and more particularly to a flame tester of the type adapted for testing the height and degree of heat from gas burners commonly used in kitchen stoves.

My invention generally consists in a pair of spaced disk plates secured together, the upper plate being a predetermined distance above the flame source to indicate the height of the flame, and a heat register is mounted on the upper plate to indicate the degree of heat from the flame.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention according to the best mode I have thus far devised but it will be understood that various changes and alterations may be made in the exemplified structure within the scope of the appendedclaims.

In the drawings:

Figure 1 is a top plan view of the tester of my invention.

Figure 2 is a vertical sectional view thereof taken at line 22 of Figure 1.

Figure 3 is a bottom plan view of the tester.

Referring now to the drawings in detail, I have illustrated the flame tester of my invention including a bottom plate 2 formed of metal preferably cast and having annular rings 4 thereon forming annular grooves 6 therebetween. These rings and grooves strengthen the plate and prevent warping thereof.

A group of central openings 8 in the lower plate permit the passage therethrough of the flame being tested and the height of the flame may be judged with relation to the upper plate referred to hereinafter.

Riveted posts l secured to the bottom plate, support the upper or top plate I2 in permanent relation and this upper plate is also provided with annular rings l4 forming annular grooves I 6 to prevent warping of the plate.

Vertical supports iii are secured on the upper plate l2 and carry thereon the heat register or indicator 20 in an angular position to facilitate reading when the tester is in position on the grill or frame coverin the conventional gas burners.

Diametrically opposite on the circumference of the heat indicator 20 I have placed the arms 22 pivotally mounted thereon and carrying the handle 24 therebetween, and the brace 28.

The handle and its arms being pivotally mounted on the heat indicator may be swung to the position best seen in Figure 2 after the flame tester has been properly located on a stove so 2 to \avoid interference with the reading of the tester.

The flame tester of my invention is placed when in use upon the grill or frame covering the gas burner and the burner is ignited.

The height of the flame will be seen relative to the height of the upper plate, the flame extending upwardly through the openings 8 of the lower plate, and the height of the flame may be adjusted accordingly by conventional means on the gas supply line.

The degree of heat of the flame will be indicated on the heat indicator, and if necessary suitable adjustment may be made to increase or decrease the heat.

The tester is sturdy in construction and simple to manufacture and will prove eflicient inoperation.

Having thus fully described my invention what I claim as new and desire to secure by Letters Patent is:

1. A flame tester for gas burners comprising spaced plates and means for securing the plates in position with relation to each other, the lower plate having central flame openings therein whereby the height of the flame passing therethrough may be tested as to height, and a heat indicator on the upper plate.

2. A flame for gas burners comprising a lower plate formed with central flame openings therein, and an upper plate secured to the lower plate in fixed, spaced relation, a heat indicator on the upper plate, and said plates having spaced annular rings thereon forming annular grooves therebetween to strengthen the plates and prevent warping thereof.

3. A fiame tester for gas burners comprising a pair of spaced plates adapted to be placed over a gas flame, the lower plate having central flame passageways therethrough whereby the flame may be tested as to height with relation to the spaced upper plate, annular rings forming grooves therebetween on the plates, vertical posts on the upper plate, and a heat indicator mounted on said posts.

4. A flame tester for gas burners comprising a pair of spaced plates and means for securing the plates, the lower plate having central flame passageways therethrough whereby the flame may be tested as to height with relation to the upper plate, annular rings forming grooves therebetween on the plates, vertical posts on the upper plate, and a heat indicator mounted on said posts.

WILLIAM F. WAGNER.
