MANTLE-HOLDER.

SPECIFICATION forming part of Letters Patent No. 632,497, dated September 5, 1899.

Application filed March 6, 1399, Serial No- 708,0Z2. No modeLl To all whom it may concern:

Be it known that I, ARTHUR KrrsoN, a subject of the Queen of Great Britain, and a resident of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Mantle- Holders, of which the following isa specification.

My invention relates in general to burners employing incandescent mantles, and is more specifically designed to provide a convenient form of mantle-holder to be used with vaporburninglamps. In suchvapor-burninglamps the necessity for removing the mantle for cleaning or replacing parts of the burner and similar purposes arises more frequently than is the case with burners using ordinary illuminating-gas, and it becomes desirable to have means for readily removing and replacing the mantle without danger of breakage. The preferred form of apparatus for accomplishing this result is illustrated in the accompanying sheet of drawings, in which Figure 1 is a side elevation of a vapor-burner and its connections with my improved mantleholder in position. Fig. 2 is a detail view of the mantle-holder.

Throughout the drawings like referencefigures refer to like parts.

The parts of the vapor-burning apparatus illustrated are of familiar type, consisting of the burner 1, the mixing-tube 2, the vaporizing-tube 3, the globe at, and chimney 5. The incandescent'mantle 6 is sustained by a Wire 7; but this wire 7 I prefer to bend away from the mantle in a bow shape, so that the central portion 8 opposite the central portion of the mantle is farthest away from said mantle. The lower end of the wire support or mantleholder 7, instead of being stepped in a lug permanently fastened to the burner l, as in the usual construction, is stepped in a ring J, which fits loosely over the burner l and has its lower projecting part 12 resting on a head or shoulder 10 or other projection formed on said burner at the proper elevation. A further adjustment may be obtained by having the wire 7 movable in the ring 9 by a set-screw 11 and held in the proper position for any given length of mantle. The ring shaped portion 9 just slips over the top of the burner, embracing the same and holding the apparatus in position, but has to be lifted up only a little way to enable it to clear the burner, thus providing for the easy and safe removal of the mantle from lamps where the vaportnbe is only a short distance above the top of the mantle.

The mode of operation of my invention is as follows: The lamp-trimmer removes the ring 9 and attached mantle-holder to mount a new mantle. He is thus able to work at ease without danger of knocking the mantle against the other parts of the lamp. lVhen the mantle is supplied by the manufacturer already mounted on the wire 7, the same may be inserted in the ring 9 and clamped by the set-screw 11. The ring 9 may then he slipped over the burner 1 and brought to a bearing on the shoulder 10. The operator has to use only one hand in doing this, the other being free to steady the lamp. After the mantle has been used awhile it becomes excessively fragile, and with the ordinary form of holder it is almost impossible to remove for any purpose without breaking it. WVith my invention, however, the mantle may be removed without jarring it by simply lifting off the ring 9.

The advantages of my invention reside in the convenience of manipulation and saving of mantles above described, while at the same time the projecting portion 12 of the ring acts to hold the mantle-supporting wire securely in an upright position.

It is evident that various changes could be made in the details of construction above described without departing from the spirit and scope of my invention. Other means of supporting the ring than that shown might be employed, other loosely-fitting forms of apparatus might be substituted for those illustrated or the supporting-wire might be bent in diiferent shapes and clamped in different ways; but all these and similar variations I consider changes of form and not in substance and still within the limits of my in vention.

Having therefore described my invention, burner, and having a downward projection What I claim as new, and desire to protect by which rests on said shoulder, and a mantle- Letters Patent, is holder adj nstably mounted in said ring.
