ZQZSAG? Dec. 10, 1935. c. w. DAVIS INVERTED MANTLE HOLDER Filed Jun'e 16, 1932 iNVENTOR, CORTLAND W. DAV
Patented Dec. 10, 1935 PATENT OFFICE INVERTED MANTLE HOLDER Cortland W. Davis, Alexandria, Ind., assignor to The Mantle Lamp Company of America, Chicago, 111., a corporation of Illinois Application June 16, 1932, Serial No. 617,554
25 Claims. (01. 67--50) The invention relates to holders for thoriumimpregnated mantles of the soft or rag type which, hitherto, have been tied by unskilled users to the blue-flame burners on which they are to be employed, and there incinerated in the usual manner.
These rag mantles often give unsatisfactory service on the burner when tied to the outside of the burner by asbestos cord which, due to the inexperience of the user, produces objectionable wrinkles in the mantle that remain after it is incinerated on the burner. Furthermore, incinerated mantles produced from rag mantles tied by the user to the exterior of a burner often become loosened from the burner after the mantle has become incinerated, due to the fact that the user did not properly secure the rag mantle to the burner.
' These objectionable features of these prior-art rag mantles are eliminated by the present invention, which embodies a mantle support to which a rag mantle may, without distortion, be properly secured in the factory by a skilled workman. The new mantle support makes it possible for an unskilled user to quickly and easily position these mantles at a predetermined and most favorable location of the mantle relative to the burner. The new mantle support further comprehends the inclusion of a wire-gauze or similar diaphragm that prevents the flashing back of the flame of the burner and makes it possible to renew this diaphragm with each new mantle support.
This invention also comprehends means for supporting the mantle holder from the inside of a burner head where it is subjected to the cooling influence of the inflowing combustible mixture, and thereby prevented from oxidizing and adhering to said burner.
The invention will best be understood if reference be had to the accompanying drawing showing its preferred embodiment, and in which- Figure 1 shows in elevation a lantern equipped with the improved mantle holder;
Figure 2 is a vertical sectional view of a burner head in which said mantle holder is to be secured; and
Figure 3 is a vertical sectional view of said mantle holder, the mantle being removed therefrom.
Referring to the drawing, Figure 1 shows a lantern having a reservoir I for liquid fuel which, under the pressure of a super atmosphere disposed above the level of said liquid fuel, flows through a vaporizer 2 to a jet orifice 3 from which 7 point.
it passes with entrained atmospheric air to a mixer 4 and thence to a burner head 5.
A preheating burner 6 of suitable type, receiving liquid fuel from any convenient source through a pipe I, is employed to initially vaporize the liq- 5 uid fuel in the vaporizer 2.
The tubular burner head 5, which is screwed on or otherwise secured to the extreme end of the mixer 4, is interiorly provided with a groove 8 and with a tapered interior wall 9 extending upward 10 to said groove 8.
The mantle holder II) has a cylindrical body I I which fits said tapered interior wall 9, and from the upper margin of said cylindrical body ll rise resilient prongs l2 having outwardly and in- 15 wardly-curved, upper ends lZa which interlock with said groove 8 when said mantle holder i0 is connected with said burner head 5, the resiliency of said prongs I2 being such as to permit them to retract while rising past the tapered interior wall 20 9 of said burner head 5 and to cause their upper ends to interlock with said groove 8, to thereby hold said mantle holder I 0 in position within said burner head 5. i
It will be observed that the cylindrical body I l 25 of the mantle holder [0 fits the cylindrical lower portion of the inner wall of the burner head, thus producing a tight joint which prevents the escape of the combustible mixture. The lower end of said mantle holder I0 is pro- 30 vided with a seat l3 for the reception of the upper end of a rag mantle, and with a wire-gauze diaphragm l4 that prevents the flashing back of the flame within the mantle, which in Figure 1 is designated by the numeral l5. Said lower end is 35 of less diameter than the body of the holder, so that the mantle which is to be attached thereto will lie close to the burner flame.
By fitting the mantle holder within the burner head 5, where a comparatively low temperature 40 is maintained by the shielding influence of said Having thus described my invention, what I claim is:
1. A holder for an inverted incandescent mantle, having a tubular lower end for the reception of the upper end of a mantle, and an inwardly-yielding and outwardly-expanding upper end having exterior means for engaging with a depression within a burner head.
