MANTLE-IBURNER.

Application filed August 2, 1918.

To all whom it may concern:

Be it known that I, SAMUEL J. BROWN, a citizen of the United States, residing at Hardinsburg, in the county of Breckinridge and State of Kentucky, have invented a new and useful Mantle-Burner, of which the following is a specification.

The device forming the subject matter of this application is a burner, adapted to form a part of an oil lamp and to carry a mantle. One object of the invention is to provide a mantle burner which will fit any lamp. Another object of the invention is to provide novel means whereby the supply of air may be regulated to secure perfect combustion, to avoid odor, and'to secure a clear white light. A further object of the invention is to provide novel means whereby the wick is operated and controlled. The invention aims to provide a structure of the kind mentioned, which will operate without a mantle, should it be desired to dispense with the mantle. It is contemplated that the device forming the subject matter of this application may be taken dowln readily for cleaning. Another object of the invention. is to provide a structure of the kind claimed, whereon the mantle may be mounted without jar and without injury to the mantle.

It is within the province of the disclosure to improve generally, and to enhance the utility of devices of that type to which the present invention appertains.

With the above andother objects in view, the invention consists in the novel construc tion and arrangement of parts hereinafter described, claimed, and delineated in the accompanying drawings, itbeing understood that, within the scope of what is claimed, changes in the size, proportions and arrangement of parts may be made without departing from the spirit of themvention, a skilled mechanic being capable of workin alterations, without jeopardizing the utllity ofthe structure claimed.

In the accompanying drawings, which form apart of this application, and are to be considered in connection with the specification,

The mantle burner which forms the subject matter of this application may be embodied in a wide variety of forms, but as presenting a typical but not'mandatory construction, there is shown in Fig. 1, a portion of a lamp bowl 1 with which is connected, in any desired way, a burner including a body 2 having perforations 3 and solid portions 4 alternating with the areas wherein the perforations are located, the solid portions of the body 2 acting as air shields, as will be better understood when the description of the invention is developed. The body 2 of the burner includes a reduced neck 5 which may be threaded, as shown at 6, into the. lamp bowl 1. A tube 7 is secured to the neck 5 and may extend below the neck, the

' downwardly prolonged portion of the tube being threaded as indicated at 8 so as to afford a means whereby the burner may be assembled with a lamp body the top opening of which is smaller than the openin in the body 2, wherein the neck 5 is threaded at 6. The tube 7 is provided with notches 9, as shown in Fig. 5, these notches constituting a part of the air inlet means.

A draft tube 10 is located within the tube 7 ,and is spaced therefrom, the tube 10 being provided, adjacent its upper end, with internal projections 40, supporting a generator thimble 41, having its lower end inserted within the draft tube, the thimble being supplied with perforations 42. The draft tube 10 is provided with openings 11 disposedoppositeto the notches .9 in the tube 7, and.

forming a part of the air inlet means, the openings 11 and the notches 9 being disposed opposite to the shields 4 which form a part of the burner body 2. A drum-like closure 12 is secured in the lower end of the draft tube 10, below theopenings 11, and has opposite extensions '14 which extend outwardly plied with,

through the draft tube, across the space between the draft tube and the tube 7, and are connected to the tube 7. In this way, the draft tube 10 is secured to the tube 7, and consequently to the body 2 of the burner.

Adjacent to its upper end, the body 2 of the burner is extended outwardly to form an approximately horizontal shoulder 15 having an upstanding marginal rim 16 supinwardly extended lugs 17 (note particularly Fig. 7), the rim 16 merging into an outwardly extended annular top 18 having a depending flange 19. In the flange '19 and in the top 18, openings 20 are formed, the lower edge of the flange 19 being inclined, adjacent to one end of the opening 20, as shown at 21 in Fig. 8.

The invention comprises an annular globe holder 22, surrounding the flange 19 and supported on the top 18, the globe holder having lugs 23 struck therefrom, the lugs "projecting outwardly. The globe holder 22 may be seated on the top 18, the lugs 23 passing downwardly through the openings 20 in the flange 19. If the globe holder 22 be rotated, the lugs 23 will coiiperate with the inclined edges 21 of the flange 19 and hold the member 22 on the burner body 2, these elements thus being connected detachably, and the connection being effected without jar, and consequently without damage to the mantle 34, hereinafter described, the lugs ,23 obviously cofiperating with the inclined edges 21 without such a shock as would be produced if the lugs 23 engaged a positive stop or abutment, when the globe holder 22 is rotated. The globe holder 22 is supplied with the usual resilient fingers 24 adapted to receive a globe 26 or its equivalent, the globe being supported on a top 25, forming a part of the holder 22. Thetop 25 of the globe holder comprises an annular raised rib 27 and there are fingers 28 which overhang the rib. The rib carries an internal flange 29. A cap 30is supported on the rib 27, about the flange 29 and is retained detachably by the fingers 28, the cap having an opening 30 in its top. The device forming the subject matter of this application may, of course, be used with practically any kind of a mantle, but, as an illustration,

there is showna mantle support comprising a ring 32 seated detachably on the cap 30, and a frame 33 carried by the ring. A mantle 34 coliperates with the ring 32 and is suspended at 35 from the top of the frame 33. j i -A table 36 fits within the rim 16 of the burner body 2 and is supported on the shoulder 15, the table being supplied with an upstanding marginal flange 37 (Fig. 7). In the flange 37 and in the edge of the table, notches 38 are formed, the bases of the notches being inclined as shown at 39. The table 36 may be placed on theshoulder 15, within the rim 16, the lugs 17 entering the notches 39. If the table be rotated, the inclined edges 39 of the notches 38 will co5perate with the lugs 17 on the rim 16 of the burner body 2, and bind the table 36 firmly but detachably on the shoulder 15, within the oontour of the rim 16. The table is supplied with perforations '43 and has an upstanding neck 44 within which is secured a tube 45 provided at its upper end with an outstanding deflecting flange46. The tube 45 is spaced from the draft tube 10, and has, at its lower end, an offset 47 seated on the upper end of the tube 7, the tube 45 thus being removably supported on'the burner body 2. The tube 45 is provided with air inlets 48, registering with the notches 9 of the tube 7 and with the openings 11 in the draft tube 10. V

A rotary tubular damper 49 is journaled on the tube 45 and supported by the offset part 47 of the tube. The damper has opena with longitudinal slots 54 receiving the parts 14 which connect the bottom closure 12 and consequently the draft tube 10 with the tube 7 which forms part of the body 2. The wick tube 53, therefore, maybe adjusted vertically. A wick 58, which may consist of four strips, is located inside of the wick tube 53 and is held on the wick tube by means of bottom prongs 56 on the wick tube, top prongs 57 thereon, and flanges 55, which be ing located along the longitudinal edges of the slots 54, extend transversely of the parts of the wick 58, as shown in Figs. 3 and 5. The wick 58 may be held, further, in the wick tube 53 by means of a ring 59 located within the wick and having prongs 60 engaging the wick. Between the slots 54, the wick tube 53 has perforations 61 and there are perforations 62 in the wick tube, adj acent to its top. The wick tube 53 is supplied externally as shown in :Fig. 6, with a rack 63 engaged by a pinion 64 on a' shaft. 65 journaled in a bearing 66 carried by the burner body 2, the shaft being supplied at its outer end with a finger-wheel 67 The rotary damper 49 may be manipulated by the handle 51 so as to cause the openings 50 in the damper to register, to a greater or less extent, with the openings 48 in the tube 45. In this way, the air supplied to the space between the tube 45 and the wick tube 53, and the air supplied to the interior of the draft tube 10 may be regulated. The air also passes upwardly through the perforations 43 in the table 36 and is defiected laterally by the flange 46. The mixture burns adjacent the perforations 42 in the generator 41, oil being supplied by the wick 58 and being turned into gas at the generator. The shields 4 prevent a direct draft of air into the tube 45 through the openings 48, the air, however, entering the body 2 of the burner, through the perforations 3. The wick tube 53 and the Wick 58 retained thereon may be raised and lowered by means of the shaft 65, the pinion 64 and the rack 63.

A fine adjustment in the air supply is obtained, and the burner will give a clear lwhite incandescent light without smoke and with a minimum consumption of fuel. So perfect, indeed, is the construction of the device, that the mantle 34 may be dispensed with, if desired. The structure will fit many lamps and this is a distinct advantage over devices of this kind disclosed in the prior art, so far as my knowledge thereof extends.

Having thus described the invention, what I claim as new and desire to protect by Letters Patent of the United States of America 1s A lamp burner comprising a body; a draft tube carried by the body; means for closing the lower end of the draft tube; a wick tube surrounding the draft tube; means for moving the wick tube longitudinally; a wick carried by the wick tube and surrounding the draft tube; a table supported on the body; a third tube carried by the table and surrounding the wick tube; a rotary damper journaled on third tube, the third tube having an opening, and the body having an opening cooperating with the opening in the third tube, the damper having an opening movable into and out of registration with the opening in the third tube; and a generator in the top of the draft tube.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
