DINNER-FAIL HEATER'.

Lisanne.

Application iled November 2G, 1913.

To all whom it may concern Be it known that I, IVALTER MILLEN TrL'roN, a citizen of the United States, residing at Franklin, in the county of Merrimack and State of New Hampshire, have invented certain new and useful Improvements in Dinner-Fail Heaters; and I do 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 improvements in heaters, and more particularly to portable stoves burning alcohol or the like.

The primary object of the invention is to provide a heater of this character adapted to many uses but more particularly designed to be removably attached to the bottom of a dinner pail.

A secondary ob3ect is to improve the structure of devices of this class to such an extent as to obviate the necessity of providing a lid or cap for the burner and yet provide efficient means for preventing the evaporation of the liquid fuel within said burner.

lWith these objects in view, the invention resides in certain novel features of construction and combination, herein described and claimed, and shown in the drawings wherein- Figure 1 is a side elevation of my improved heater showing` the same applied to a dinner pail; Fig. 2 is plan view of the heater; Fig. 3 is a vertical section of the heater and a portion of the pail, showing the burner in an operative position; Fig. i is a similar View of a portion of the structure shown in Fig. 3 and showing the disposition of the burner when not in use.

In the drawings, I have shown my improved heater as applied to a dinner pail 1 having its bottom 2 spaced upwardly from its lower end, said lower end being provided with a head 3 and with draft opening 3. The co-action of these parts with the heater will be explained below.

Coming now to the details of the present invention, my heater comprises a burner, a perforated shield 5 therefor, and spring metal clips 6 for removably attaching the heater to the pail 1.

The shield 5 is of a contour approximately the same as that of the pail to which it is to be attached, and although I have shown it Specification of Letters Patent.

Serial No. 802,108.

as cylindrical it may be any desired shape. This shield 5 is provided with a bottom 7 which carries a cup 8 at its cen er.

Removably seated in the cup 8 is a reversible fluid fuel burner 9 in the form of a shallow pan having the usual packing 10 and foraminous screen 11.

rThe burner 9 is preferably provided with an annular bead 12 on its outer face adapted for engagement with the upper edge of the iange of the cup when the burner is in operative position as seen in Fig. 3, with its open end up, or in inverted inoperative position as seen in Fig. 4f.

I provide the shield 5 with radial fingers 13 which project inwardly a suitable distance to receive the bead 12 on the burner 9, if it is desired to have it closer to the pail or vessel 1. The outer ends of these ngers are bent down at 14k into engagement with the shield 5 and then turned inwardly into feet 15. The spring metal clips 6 are then secured outside of the downturned portions 1a by passing bolts or rivets 16 through said clips, the portion 14, and the shield 5.

A very important feature of my invention resides in the fact that by the disposition of the burner 9 and its coacting parts, it is un necessary to provide a separate cover for said burner, it being only necessary to remove the burner 9 from its cup 8 and invert it when a iiame is no longer needed.

Another feature lies in the fact that by the positioning of the terminals of the fingers 13 I may employ them as supports for a vessel to be heated or as retainers for the burner 9 thus bringing its frame nearer to the receptacle 1.

I space the bottom 2 of the pail 1 from the lower beaded end of said pail and provide said lower end with the draft openings 3 for the following reasons:

If the metal clips 6 engaged the portion of the pail in which liquid is carried, they would probably in time wear holes and cause the pail to leak, but by the above described construction no harm can result from said clips wearing against the portion of the pail below the bottom 2, and by the positioning of the bottom 2 and the draft openings 3, the flame and smoke from the burner are prevented from running up the sides of the pail 1 and discoloring it. This structure also affords a heat reservoir and a draft shield directly below the bottom of the pail l where the heat can be used to the greatest advantage.

Although I have described my invention with considerable minuteness, I may under the scope of the appended claim, make various minor changes.

What is claimed as new is:

In a hea-ter of the class described, a body of cup-shaped design, a burner removably mounted in the bottom thereof, and a plurality of fingers secured to said body and extending radially inward thereover to form supports, the inner ends of said lingers being spaced slightly from one another and adapted to friotionally receive said burner therebetween for supporting the same on the upper portion of the body at predetermined times.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
