WELSBACH OR OTHER INCANDESCENT` BURNER.

SPECIFICATION forming part of Letters-Patent No. 700,157, dated May 1s', 1902. 1 ,Y

Application filed November 15, 1.901. Serial No. 82,384. (No model.)

T0 LZZ whom, it r11/Ly concern:

Be it known that I, TowNsEND STrrEs, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Welsbach or other Incandescent Burners, of which the following is a specification.

The invention relates to Welsbach and other incandescent burners. Its object is to provide simple, efficient, and comparatively inexpensive means for yieldingly supporting the mantle so that the same will be immune to sudden shocks and undue vibrations. 'n

Stated in general terms, the invention comprises a torsional spring-supported burnerhead, which serves as a carrying medium for the mantle.

The nature, characteristic features, and scope of the invention will be more clearly understood by reference to the accompanying drawings, forming part hereof, and in whichl Figure 1 is a central vertical section, partly in elevation, of an incandescent burner embodying features of the invention. Fig. 2 is a plan View of the vspring and -its support shown in Fig. 1. Fig. 3 is a sectional View illustrating the use of two springs starting and ending at different points, and Fig. 4 is a sectional view illustrating a modification.

Referring to the drawings, 1 'represents a suitable casing, having an air chamber 2 served with a shutter 3 and through which projects a Bunsen tube 4, which frictionally engages a socket or tubular member 5, coextensive with the upper wall of said air-chamber. The Bunsen tube is connected to a gassupply-pipe 6 and has the usual check 7 Near the top'of the casing l` there is provided an annular groove 8, in which is seated a torsional spring 9, of spring-wire made into the formof a iiat spiral and capable of sustaining a heavy body without losing its general transverse shape. The heavy weight or body may be that shown at 10,which is attached to the base of the burner-head 11 and has suitgaging the inner convolution of the spiral, the

outer convolution being seatedY in the groove 8. Both the weight 10 andthe burner-head encircle the neck 5 and itsinclosed Bunsen tube and both are sustained axially in respect to the spring 9, which tends at all times to seek its eqpuilibriunmso that the arrangement forms an efficient buenwhich deadens concussions and vundue vibrations, and thus prolongs the life of the mantle.

As a means for closing the annular space between the neck 5 and the weight 10 I provide a iiat disk or follower 13, which is free to slide on the neck 'and abuts the bottom of the weight 10, said follower being supported by' a spring 14,' coiled upon the neck 5, so that it accommodates itself to every move of the weighted body.

15 is a collar havingthe side support 16, in which is borne the mantle 17.

18 is a gallery-ring from which extend the uprights or posts 19 for supporting the chimney. y

In Fig. 3 two flat springsa and bare employed, and they start from different points on the gallery and end at' different points onthe burner-head. They are both normally in the same horizontal plane, and one of the advantages of using two of them is that more points of support are provided than if only one were used. In Fig. 4; the disk or follower is provided with alip c, loosely accommodated by a groove d on 'the'weight or body. lThis makes a neat loose connection between the parts.

It will be obvious to those skilled in the art to which the invention appertains that modications may be made in details without departing from the spirit and scope of the same. Hence I do not limit myself to the precise construction and arrangement of parts hereinabove described, and illustrated inthe accompanying drawings; but,

l-Iaving thus described the nature and objects of the invention, whatlclaim'n as new, and desire to secure by Letters Patentjis* 1. The combination in an incandescent burner of a rigid support, a iat spiral spring having its outer convolution attached to said support, a weighted burner-head supported and carried by the inner convolution of the spring, and a connection for supplying gas to said burner-head, substantially as described.

2. The combination in an incandescent burner, of a burner-head provided with a weight, a fiat spiral spring which normally supports and carries the burner-head and retains its general transverse shape, and a tubular connection for supplying gas to said burner-head, substantially as described.

8. The combination in an incandescent burner,of atorsional sprin g-supported burnerhead, and means supported independently of said spring for supplying a mixture of air and gas to said head, and a yieldingly-supported follower for said burner-head, substantially as described.

4:. The combination in an incandescent burner, of a burner-head, a iiat spiral spring for supporting and carrying said head, a Bunsen tube, and a yieldingly-supported follower for the burner head, substantially as de- 5. The combination of a spring-supported burner-head and a yieldingly-supported follower, substantially as described.

(i. The combination in an incandescent burner, of a rigid support, a flat spiral spring having its outer convolution attached to said support, a weighted burner-head supported and carried by the inner convolution of the Spring, and a Bunsen tube extending into the base of said burner-head, substantially as described.

'7. The combination in an incandescent burner, of argid support, a fiat spiral spring, a weighted burner-head axially supported by said spiral, a Bunsen tube extending into the base of said burner-head, and a yieldinglysupported follower for the burner-head, substantially as described.

S. The combination in an incandescent burner, of a rigid support provided with a groove, a iiat spiral spring having its outer convolution seated in said groove, a burnerhead carryinga mantle, a heavy body secured to the base ofthe burner-head and supported and carried by the inner convolution of the spring, and a connection for supplying gas to the burner-head, substantially as described.

9. The combination in an incandescent burner, of a weighted burner-head, a mantle carried thereby, a Bunsen tube extending into the base of the burner-head, a torsional spring supporting said burner-head and a yieldingly-supported follower for the burnerhead, the arrangement being such that the burner-head is normally sustained in axial relation to the spring, substantially as described.

10. The combination in an incandescent burner, of a mantle, a burner-head constructed to carry the mantle, a heavy body secured to the base of said burner-head, a peripherally-sustained fiat spiral spring the inner convolution of which carries said heavy body and constitutes its sole support, and a Bunsen tube extending into the burner-head, sul stantially as described.

1l. The combination in an incandescent burner, of a mantle, a burner-head construct` ed to carry the mantle, aheavy body secured to the base of said burner-head, a fiat spiral spring the inner convolution oi' which encircles said heavy body and constitutes its sole support, a Bunsen tube extending into the burner-head, and a spring-pressed follower for the burner-head, substantially as described.

12. The combination of a burner-head having a mantle, a weight constructed to carry the burner-head, a suitable casing having an annular groove or seat, a fiat spiral spring whereof the outer convolution takes into said groove and whereof the inner convolution sustains said weight, a connection for supplying a mixture of air and gas to the burnerhead, and a spring-pressed follower, substantially as described.

13. The combination of a spring-supported burner-head, a spring-supported follower, and a loose lip-and-groove connection between the two, substantially as described.

In testimony whereof I have hereunto signed my naine.
