fiPl-ECIFICATION forming part of Letters Patent No. 313,713, dated March 10, 1885.
(No model.)
To aZZ whom it may concern:
Be it known that I, DAVID L. DURAND, a citizen of the United States, residing at Derby, New Haven county, Connecticut, have invented new and useful Improvements in Lamp-Burners, of which the following is a specification.
My invention relates to lamp-burners, and the purpose thereofis to provide novel, cheap, and simple construction, whereby the gas-tube may be fastened in place without soldering.
The invention consists in the several parts and combinations of parts, hereinafter fully set forth and definitely pointed out in the claims.
Referring to the drawings, forming part of this application, Figure l is a plan view of the burner inverted, showing the screw part. Fig. 2 is a plan view of the deflector or chimney-base. Fig. 3 is a plan view of the ratchetcap. Fig. 4 is a perspective View of the wicktube. Fig. 5 is a perspective view of the gastube. Fig. 5 is a sectional view showing a modified construction of the gas-tube. Fig. (5 IS a central vertical section taken through the burner transversely to the greater diameter of the wick-tube.
Heretofore and prior to myinvention it has been common to fasten the wicktube in place by swaging, and to secure the gas-tube by means of projections or nipples formed in and extending slightly from the wall, a space being left between to receive the edge of the disk upon the screw part of the bottom of the burner. These nipples have also been formed at such distance apart as to engage with the opposite faces of any two of the disks in the burner.
I propose to secure the gastube by forming therein one, two, or more minute openings or perforations which shall engage with small teats or projections formed upon the edge of one or more of the disks of the burner, in such position as to engage with the openings in the gas-tube when the latter is in place and prevent its displacement longitudinally, said tube being supported laterally by the wicktube and the disk through which it passes.
In the drawings, numeral 1 denotes the wick tube of a burner of the usual construction passing downward through the chimney-base or deflector 2, through the ratchetcap 3 and the screw part 4 of the burner.
Against one of the flattened sides of the wicktube lies the gastube 5, which may be of the ordinary form. In the wall of said tube is formed an opening or openings, 6, and upon the edge of one or more of the disks 2, 3, and 4 is formed a teat or projection, 7, extending from the edge of the aperture which receives the gas-tube, and adapted to engage with one or more of the openings 6 formed in the latter. The wicletube having been adjusted and swaged in the usual manner to hold it firmly in place, the gas-tube is inserted and pushed downward to its proper position, the points or teats 7 springing into engagement with the openings 6 in the gas tube and securing it in place.
The gas-tube may be made a complete oval, as shown in Fig. 5, or it may be formed in the manner shown in Fig. 5, a great-er or less portion of one of its flat vertical walls being omitted. It will of course be understood that when agas-tubeis made somewhat open at one side such open side may be arranged against the side of the wick-tube. Where the tube has a complete oval form ,the teat or projection may be formed in the wall of the wick-tube, as shown at 7, Fig. l, said projection engaging with an opening cut in the gastube in that wall which lies adjacent to the wick-tube. By this construction I provide a cheap, simple, and very convenient means ofsecuring the gastube in position.
I do not claim a gas-tube having attached projections arranged to engage the edge of one of the disk-like parts of a burner. In such construction it is diliicult to properly form the projections on the gas-tube, and this I avoid by my invention.
Having thus described my invention, what I claim is 1. In a lamp-burner, the combination, with the wick-tube, of a gas-tube having one or more openings engaging with a teat or pro- 5 ICO in its wall, of a teat or teats formed upon In testimony whereof I affix my signature one or moreof the parts against which said I in presence of two witnesses. tube has lateral support, substantially as described. DAVID L. DURAND.

7, formed upon one, two, or more of the disks JOHN E. LEWIS,
2, 3, and 4, substantially as described. E. T. HARDING.
