GAS-MANTLE RING.

Specification of Letters Patent.

Application filed August 29, 1916. Serial No. 117,481.

To all whom it may concern:

Be it known that I, JOHN G. Go r'rr, a citizen of the United States, reslding at Jacksonville, in the county of Duval and- State of Florida, have invented certain use' ful Improvements in Gas-Mantle Rings, of which the following is a specification, reference being bad therein to the accompanying drawing.

The object of the present invention is to provide a support and improved fastening ring for inverted incandescent mantles which will be positive in its action, and more simple in construction and inexpensive to manufacture than the devices now known in the art.

A further object of my invention is to provide a fastening means for mantles of this type which will also form a shield for the portion of the mantle in contact with the support, thereby eliminating the chance of splitting the mantle fabric along the edge of the support.

Referring to the accompanying drawings which illustrate the embodiment of my invention, and in which like reference characters indicate like parts throughout the several views, Figure 1 is an elevation, partly broken away, showing my improved fastening ring applied to a mantle upon its support.

Fig. 2 is a perspective view of an improved fastening ring in its open'position.

Fig. 3 is a similar view showing the ring in its closed position.

Fig. 4 is a perspective view showing a slight modification.

In the drawings, a support for the inverted incandescent mantle 1 is shown, comprising sustaining lugs 2 and a depending annulus 3, which is externally grooved as shown at 4 to receive the top edge of the mantle fabric as shown in Fig. 1.

My improved ring for holding the upper edge of the mantle within the groove 4, comprises a flat ring 5 of slightly greater width than the annulus 3,'and formed with an out- 7 wardly extending tongue 6 upon one end,

and having a vertical slot 7 adapted to receive the said tongue adj acent the other end. The ring 5 is of such a length that when it is bent around the annulus 3 above the mantle, the tongue 6 may be inserted in the slot 7 and by pulling upon the tongue and bending it back upon the ring as shown in Fig. 1,

the ring will be held tightly above the mantle thereby fastening the same in position.

The ring 5 is made of any suitable material which will readily bend laterally, thereby p'ermittin'g'the ring to assume approximatelythe same contour as the external face of the annulus, and so preventing any severe strain upon' the mantle fabric at any one point.

-By making the fastening ring of a greater width than the annulus, all parts of the fabric which are in contact with the annulus are protected from exterior pressure of any kind. The ring 5, at its bottom or lowermost edge, is slightly outwardly flared, as at 8, so that when the ring is in position upon the annulus 3 with the mantle mounted thereon, the free lower or bottom edge will not contact with the mantle. Formed at the upper edge of the ring 5, are spaced bendable ears 9, which are bent inwardly and downwardly to rest upon the top of the annulus 3, so as to avoid any possibility of the slipping of said ring downwardly upon the annulus, when the ring is-mounted thereon for holding the upper edge of the mantle within the groove 4, formed in said annulus.

In Fig. 4 there is shown a slight modification wherein the ring 10 is in the form of a circular band, unbroken throughout its extent, and is formed at the upper edge there- .placed around the same annulus with the said tongue engaging the said slot to adjustably clamp the above mentioned mantle to the said annulus, the said ring being adapted to bend laterally to conform to thecontour of theouter surface of the said annulus.

2. The combination with a supporting annulus of a mantle having its edge overlapping the same, and a fastening ring having a tongue and slot formed upon opposite ends thereof, and adapted to be placed around the said annulus with the said tongue engaging the said slot to adjustably clamp the above mentioned mantle to the said annulus.

Patented May 22, 1917.

3. The combination with an externally intervals on the uppermost edge of said ring grooved supporting annulus of a mantle for engagement with the annulus at the top overlapping the same, a ring adapted to be thereof to prevent downward displacement 10 placed around the said annulus, the said ring of the ring thereon.

5 being adapted to bend laterally to conform In testimony whereof I aflix mysignature.

to the contour of the outer surface of the 7 said annulus, and bendable ears formed at JOHN G. GOTTY.
