MANTLE-C i1 To all whom a't may. concern: Be it known that 1, SMITH, a citizen of the United Statesfresiding at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in. Mantle-Caps and. Burner-Cones; 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.
In the manufacture and operation of incandescent vapor gas lamps employing a burner cone of the type illustrated in my prior Patent No. 988902, dated April 4, 1911, considerable dificulty has been experienced in manufacturing a cone ofthe type therein cone cap, and the top of the outside wick disclosed to retain the same in position on a burner. It has been found that it is necessary to holdthe depth of the burner cone to a predetermined, definite measurement, to coiiperate with the burner spreader, the
tube flange of a burner with which the cone is designed to be used. The cone should be mounted on the burner with certain predetermined relation to-the upper ends of the wicktubes and the structure carried thereby.
ll'n-the manufacture of these cones, it has 1 been. found diflicult to maintain the accuracy of the construction of the cone when made by the old method, in that the body of the cone is liable to be distorted outof its true circular formation. c
This invention contemplates the provision of improved means for retaining amantle cap to the gallery of a burner, as well as improved features in the construction of the cap, such features residing in the provision of means to prevent the lower section of the cap from getting out of round, that is to say, being distorted fromits true circular formation.
In carrying out the invention, a practical form is disclosed in the accompanying drawings, wherein novel attaching means are provided for the cap to be associated with means carried by the burner gallery. The burner cone is illustrated as having a substantially Specification of Letters Patent. Applieationfiled Octohei 15 1915. Serial no. aae.

"conical form, as disclosed in Iny prior patcut. but 111 addition thereto, there is provided.
an annular flange having a notch which is designed to permit an ear, carried by the burner gallery to pass through the notch and engage'the flange. The notch does not extend to the full depth of the flange, thereby retaining the strength of the flange at the .base. of the cap, to prevent'distortion of the cap. it ispreferred also to provide frictlonal lockmg means on the flange which may be effected by upturning the edge of the flange ad acent the cut out portion, and if desired. by upsetting the edge of the flange opposite to the upturned edge to make a nonentrantst-op to engage the gallery retaining mechanism, thereby making it impossible to attach the cap in an incorrect manner to the gallery.
In the accompanying drawings,
Figure 1 is a slde elevation, disclosing a burner cone with a mantle and a mantle support maintained in position thereon.
Fig. 2 1s a vertical, sectional view through the burner cone and mantle support.
Flg. 3 is a plan view of the burner cone and mantle support.
Fig. 4 is a bottom plan view of the burner CORG- 5 is a detail view, in side elevation, of locking means carried by the, burner to en- I gage the slots of the burner cone- Fig. 6 is a detail plan view of the means to lock the burner cone disclosed in Fig. 5.
,Referring to the embodiment of the de v1ce illustrated in the accompanying drawngs, the burner cone is illustrated at 1, and is shown contracted at the upper portion as at'2. The upper portion 2, terminates in an inturned, annular flange, indicated at 3, and
. providing a central opening 4:. The wall of the member 1 is shown as substantially vertical, and at its lower edge is provided with a protruding or external annular flange 5. This flange may be of any desired width,
and is preferably positioned to form the of the fuel. For this reason, the flange 3 and the flange 5 of the cone-cap are essential parts of a structure for thepurposes described, and it is desired to maintain their relative positions in the completed article. Moreover, the proper circular formation of the parts 1 and 2 should be maintained to secure uniform and properair passage between the inside of the cone and the wick tube flange. It should be noted, however, that the accompanying drawings are not made to a scale, but are merely presented as illustrative of a practical form of the device.
The side of the member 1 of the burner cone may -be perforated as at 6 to receive tongues 7 of a supporting element 8, which is adapted to be secured by means of the.
The mantle support is preferably of a continuous piece of metal, such as wire, bent to formthe side members, the ends of which are adapted to be secured permanently in the tubular members by compressing the metal of said tubular member, as at 11, to
securely bind the wire 10. Intermediate the ends of the wire 10, the side members may be bent as at 12, toward each other, to an upper extremity 13. The part positioned between 12 and 13 is curved to form a seat as at 14, upon which may rest a suitable protective element, not shown, in the packing and shipping of the mantle. Between the elevated curved portions 13, the wire is bent downwardly to form a widened notch 15, which serves as means to suspend a mantle 16 by means of its suspension loop 17. The inclination of the wire from the points 13 to the center of the notch 15 is preferably central of the burner cone, so that the mantle will hang substantially central of its wire supporting element. By this arrangement, the lower portion 18 of the mantle will inclose the conical upper part 2 of the burner cone-cap.
In the practical operation of a lamp,.it is desired that the combined mantle cap and burner cone shall be securely mounted upon the burner. One means of locking the burner-cone upon the lamp is shown in the accompan g drawings, wherein the flange 5 is provi ed with a notch 20, which does not extend the full depth of the flange, but leaves a part of the flange, indicated at 21, interposed between the notch 20 and the side wall of the mantle cap 1. This remaining portion of the metal of the flange 5, serves to strengthen the cap circumferentially'at the base to prevent in ury to the cap in distorting it out of its proper circular formation.
In Figs. 3 and 4, a plurality of these notches 20 are illustrated, such notches being positioned opposite to each other. These notches notches bein are desig ed to cotip ratewith a lockin m 22 carried by a part of the burner, suc as the horizontal flange of the carrier, The ear 22 is shown stamped up from the metal of the burner, and may be elevated more at one end, as at 23, than at the other end, as at 24 from the structure from which it is stamped up, to thereby provide an inclined locking 7 cap may thereafter be pressed upon theburner so that its annular flange 5 bears;
upon the burner partsto which it is to be applied, and rotated to'bring the ear 22 into engagement with the unnotched part of the flange 5. To rotate the flange in one direction, and thereby insure the proper adjust-- ment of a cap u on the burner, the edge of the flange 5 ad acent the slot 20 may be.
slightly turned up as at 25 to form a nonentrant obstruction. To securely bind the burner cone to the burner structure, the edge of the flange op osite to the non-entrant edge 25 may be sllghtly turned u along theedge of the flange 5 as at 26, Sue upsettin l or turning up of the edge, 26 bein gradua from the slot 20, but it is referre that this upsetting of the edge 26 v all not extend the full depth of the flange.' By this arrangement, the inclination of the edge 22, cotipcrating with the inclined edge 26, as shown in Fig. 1, will rovide the adual engagement between ,t e ear 22am the flange 5 to securely maintain the burner cone in position on the burner.
It is obvious that various alterations and modifications may be made in the form and operation of the parts to meet the exi-- gencies of the service of the cone-cap. The right is reserved, therefore, to make such changes andalterations as fairly fall within the scope of the ap ended claims.
Havin thus describe my invention, what I c aim as new and desire to secure by Letters Patent, is:
1. As an article of'manufacture, a combined mantle cap and burner cone comprising a base .having an annular flange provided with opposed notches which extend into the flange for a part of the depth thereof, the ed of the flange adjacent the lstorted to provide means to be engaged y a locking device.
2. san article of manufacture, a burner cone-cap having a contracted upper portion terminating in an inturned annular flan and a lower, annular flange forming the 51%;- porting basefor said cone-cap provided with a notch, the flange being upset at its outer edge to secure the cap in its adjusted position on a burner.
3. As an article of manufacture, a oommeaeae comprisannular lower flange spaced at a predetermined position with relation to said upper flange, a looped wire mantle support having its extremities secured to said cap, a mantle secured on said support to be maintained in positionby the mantle cap carried by the said lower flange being provided with a notch, and retaining means comprising the upsetting of the outer edge of the flange adjacent said notch. 4
