AUTOMATIC FLAME-REGULATOR.

Specification of Letters Patent.

Patented Sept. 25,1917.

Application filed lune 1, 1916. Serial No. 101,066.

To all whom it may concern:

Be it known that I, Josnrrr KRIZAN, Jr., a citizen of the United States, residing at Groom, in the county of Carson, State of Texas, have invented certain new and useful Improvements in Automatic -Fla1ne-Regulators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to temperature regulating devices for incubators, and has particular reference to devices for controlling the amount of heat generated by the heat source of an incubator.

The primary object of my invention is to provide a simple and inexpensive device of the character above mentioned which acts to regulate the size of the flame of the heating lamp employed in an incubator.

More particularly, the invention purposes to provide a device, which, as a unit may be mounted upon the chimney of an incubator lamp so as to be removable therewith, and which is adapted to slidably surmount the wick so as to expose regulated portions. of the flame end of the wick thereof which may burn while the remainder of the flame end is covered to reduce the flame.

With the above and other objects in View, as will hereinafter appear, my invention will now be fully set forth and described, reference being had to the accompanying drawings.

In said drawings Figure 1 is a vertical section through the burner and chimney of an incubator lamp, showing my improved device attached thereto,

Fig. 2 is a section on line 22 of Fig. 1, with parts of the mechanism broken away for the sake of clearness,

Fig. 3 is a section on line 3-3 of Fig. 1, and

Fig. 4 is a detail elevation of one of the parts of the device.

Referring more particularly to said drawings, 1 represents the burner of the incubator lamp having the usual cap 2. The sheet metal chimney 3 is removable, and rests upon the body 4 of the lamp. Mounted upon the side of the chimney 3 is a housing 5 which is preferably formed of sheet metal and is arched out from the chimney so as to down-turned in such be secured thereto by its edges. Penetratlng the arched portion of the housing 5 is an elongated opening 6 which registers with a correspondingly formed opening 7 formed in the wall of .the chimney 3. The openings 6 and 7 provide spaced bearing points for a slide 8 whose inner end is formed into a dished blade 9 whose, longitudinal edges are spaced relation as to inclose the flame end of the wick in the burner 1 when the blade 9 overlies the burner.

The blade 9 is adapted to be slid to en tirely or partially cover the flame end of the wick, and has its outer end 10 connected to a pivoted rod 11,-which is journaled in a bracket 12. The rock arm or rod 11 is connected to the end 10 by being freely projected through a vertical opening provided in said end.

As best seen in Fig. i, the pivoted rod 11 is provided with the journal portion 13 which rocks in a bearing 14E formed on the outer end of the bracket 12. On the opposite end of the journal 13 the rod 11 is continued in the horizontal arm 15. Said arm 15, at its free end is provided with the loop 16 to which is linked the vertical rod 17 which is connected to the thermostat (not shown). The rod 17 reciprocates under the action of the thermostat, and communicates its motion to the rock arm or rod 11, and which in turn reciprocates the slide. Extending in the opposite direction from the arm 15 at the upper end of the rock arm 11 is an extension 18, which supports, at its free end a weight 19, which normally counterbalances therock arm 11 and the slide 8, so that when the temperature in the incubator is at the normal point, the weight 19 will hold the blade 9 free from the wick.

In the operation of the device, as above stated, the weight 19 normally holds the blade 9 out of its covering position, as indicated in Fig. 1. However, when the tem perature in the incubator becomes too high so that the thermostat is effected, the rod 17 is lowered, so that the arm 15 is turned downwardly, the rock arm 11 turned toward the chimney 3, so that the slide 8 is pushed inwardly until the blade 9 cuts off the flame to a greater or less degree, in accordance with the temperature drop required. When the chimney 3 is removed, the entire cut-off device is carried therewith, the connection between the arm 15 and the rod 17 being such that it can be readily disconnected upon occasion.

From the foregoing description it Will be evident that I have provided a very simple but eflective device Which may be interposed between a thermostat in an incubator and the burner for regulating the temperature, a device not only Working effectively, but rapidly to bring about the desired temperature changes.

What I claim as my invention is The combination With an incubator lamp, a burner and a chimney thereof, a slide adapted to variably cut off the flame of the burner, said slide having a bearing in the Copies of this patent may be obtained for five cents each, by addressing the Wall of the chimney, and sliding longitudinally along the upper end of the Wick, a rock arm supported by the chimney and having a pivotal connection With said slide, .a thermally controlled rod connected to said rock arm, an extension on said rock arm, and a Weight upon said extension positioned for normally holding the slide Withdrawn from contact With said burner.

In testimony whereof, I afliX'my signature, in the presence of tWo Witnesses.
