ing drawings, forming a JOHN GARRIGAN, OF NEW YORK, N. Y.


Specification of Letters Paterit.

Patented March 5, 1907.

Application filed February 14, 1906. Serial No. 301.002.

T0 ctZZ whom it may concern:

Be it known that I, JOHN GARRIGAN, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Coffee and Tea Flask, of which the following is a full, clear, and exact description.

This invention relates to improvements in flasks for coffee, tea, or other liquid that it is desirable to heat before drinking, the object being to provide a simple and novel heating device with means for removably holding it in position; also, to provide the flask with a center draft-tube down which air is drawn to cause the lamp-flame to spread over the bottom of the flask, thus causing a quick heating of the liqui I will describe a coffee and tea flask embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanypart of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a section, on the line 1 1 of Fig. 2, of a flask embodying my invention; and Fig. 2 is a section on the line 2 2 of Fig. 1.

Referring to the drawings, 5 designates a flask-body, 7 a cover therefor, and 6 a drafttube, said draft-tube extending down through the cover 7 and also through the bottom 8 of the flask at about its center. A downward extension 9 from the bottom of the flask provides the wall of a chamber for containing the lamp to be hereinafter described, and this downward extension 9 is provided with air-inlet openings 10. The lamp consists of a tube 11, having a slot extended lengthwise of it at the top, as indicated at 12, and arranged across this slot is a screen material 13, while within the screen material is an absorbent 14, preferably asbestos, for containing alcohol.

Mounted to rotate on the tube 11 is an outer tube 15, also provided with a slot 16. By rotating the tube 15 on the inner tube the size of the flame may be regulated, or by entirely closing the opening through the inner tube the flame may be entirely out off upon a complete turning of the outer tube.

As a means for supporting the lamp I employ a socket member 17, into which one end of the lamp may removably engage. This socket member is connected to the wall or downward extension 9 by means of a spring 18. This spring is substantially U shape, one leg thereof being secured to'the wall 9, while the other leg is secured to the lower side of the socket member, and said lower side of the socket member has a downwardlyextended lug 19.

In the operation when it is desired to insert or remove the lamp a person by placing a finger on the lug 19 and his thumb on the outside of the wall 9 may spring the socket I member downward, so that the free end of the lamp projects below said wall 9,where it may be readily grasped to remove the lamp. To insert the lamp, obviously the socket member is to be drawn down, as above mentioned, and after placing the lamp end therein and releasing the lug the spring will move the parts up into the lamp. When the lamp is burning, atmospheric air will be drawn down through the tube 6, causing a spreading of the flame over the bottom of the flask to quickly heat its contents.

While I have described my invention as in connection with a flask, it is obvious that it may be used in connection with a dinner pail. In fact, it may be used in connection with any vessel in which material is to be heated. Therefore it is to be understood that the term flask is designed to cover such pails or vessels.

Having thus described my invention I claim as new and desire to secure by Letters Patent 1. A flask having a chamber below its bot tom wall, a draft-tube extended through the top and bottom of the flask, a spring-supported socket member in said chamber, and a lamp for removably engaging in said socket member.

2. A flask, a center draft-tube extended through the top and bottom of the flask, a wall extended downward from the bottom of the flask and forming the wall of a chamber below the bottom of the flask, a socket member, a spring connection between said socket member and said downwardly-extended wall, a lug on the lower side of the said socket member, and a lamp for removably engaging in said socket member.

3. A flask, a center draft-tube extended through the top and bottom of the flask, a downward extension from the bottom of the flask, forming the wall of a chamber below said bottom, a socket member, a substantially U-shaped spring having onedeg con- ITO nected to said downward extension and the other leg connected to the lower side of the socket member, a lug on the lower side of the socket member, and a lamp for removably engaging in said socket member.

4. 'l he combination With a flask and a socket member supported below the bottom Wall of the flask, of a lamp comprising a tube having an opening at the top, a screen mate rial extended across said opening,(asbestos or the like) Within the tube, and an outer tube mounted to rotate in the first-named tube, the said outer tube being provided with an opening.

In testimony whereof I have signed my r 5 name to this specification in the presence of tWo subscribing Witnesses.
