GEORGE A. HALL, OF BUFFALO, NEW YORK, AssIGNOR TO LOOK LAMP BURNER COMPANY, OF BUFFALQNEW YORKLA CORPORATION OF NEW YORK.

LAM P-BURNER.

SPECIFICATION formingpart of Letters Patent No. 728,166, dated May 12, 1903.

Application filed July 25, 1902. $e1ial No. 117,016. (N0 model.)

To all whom it may concern.

Be it known that I, GEORGE A. HALL, a citizen Of the United States, residing at Buifalo,

in the county of Erie and State of New York,

have invented certain new and useful Improvements in Lamp-Burners, of which'the following is a specification.

This invention relates to that class of lampburners which are provided with chimneyholding arms adapted to impinge against the Other objects are to provide a simple, efficient, and reliable'burner in which the chimney-holding arms are simultaneously operated bya movable annulus, which latter when moved in one direction will cause the chim ney-holding arms to be locked in their impinging position against all jarring and shaking of the lamp and will be held in such-locked position until by the exertion of sufficient force the said annulus is moved in the opposite direction.

To this end my invention consists of a burner having a number of vertical rock-arms with curved impinging upper ends and cranks at their lower ends, an annulus having radial slots with which the crank ends of the said rock-arms engage and which is; arranged to turn back and forth on thebu'rner-body. It also consists in the new and novel arrangement and construction of parts, as will be hereinafter described, and more particularly pointed out in the appended claims.

In the drawings, Figure 1 is a central vertical section of a burner embodying my invention and used in connection with a lampchimney. Fig. 2 is a side elevation of my improved burner, showing the chimney-holdin g arms rocked to engage the'inner side ot'a' lamp-chimney. Fig. 3 is a similar view showing the chimney-holding arms rocked to permit the lamp-chimney to be secured to or removed from the burner. Fig. 4 is a plan view of the burner, showing the chimney-holding arms in the position they assume when impinging againsta lamp-chimney. Fig. 5 is an invertedview of'ihe burner.

;S .iinilar1numerals of reference indicate cor- 1i respondingpartsin the several figures.

The numeral 1 designates the lamp-burner -takenas-a=whole, and 2 the lamp-chimney.

Thefburne'r-body 3 may be of any common construction having a rim or chimney-gallery 4, a wick-tube 5, wick-raising mechanism 6,

slotted cone 7, and screw-neck 8, which is screwed into the oil-reservoir of the lamp. Vertically-disposed chimney-holding arms 9 are journaled to rock in the gallery? or other suitable part of iheburner and at their upper ends are preferably curved outward and upward to conform to the shapeot the chimney. It is obvious thatif the chimney isof a shape diiferent fromfthatshown .in the drawings hereof these arms will beishaped to conform thereto. Thelower ends of the chimneyrhol'dinga'rrns are .offset or bent into the form of cranks 10. To keep these chimney-holding arms in their proper'position, each is provided with acollar 11, which bears against the upper end of a'bearing-sleeve 12, secured to, but forming part of, the chimney.- gallery. Any other arrangement of journalin g the chimney-holding armsmay be resorted to without departingfroin my invention.

Held On thebody of, the burne'r so as to partly revolve backand forth is an'annulus 13, which may be Of.-any..'construction and which is provided with. radial slots-14, with which the lower crank endsfo-fthe chimneyholding arms engage. The disposition of the crank ends of the-said arms are so arranged with reference to the upper impinging ends thereof that the turning of the annulus 13 in one direction causes the'cranks 10 to ride in the radial slots and simultaneously swing On the journals of the arms of which they form part, while the impinging upper ends are swung inwardly to clear the baseof the lampchimney, thus permitting the latter to ,be removed with ease and without obstruction and when removed allowing the same to be seated against the gallery of the burner. On

ICO

turning the said annulus in the other direction the crank ends, by the medium of the radial slots in which they are held,are'again caused to ride in said slots and simultaneously swing on the journals of the arms of which they form part, while the upper impinging ends of the chimney-holding arms are swung outwardly against the lamp-chimney and slightly beyond the dead-center to lock the arms against movement except by the turning of the annulus 13 in the reverse direction from that last described. As the impinging ends of the chimney-holding arms reach the dead-center the crank ends thereof have about reached the inner end of the radial slots 14, and the further movement of said crank ends is only sufficient to permit the upper impinging ends to pass the deadcenter, where they are locked against further movement by the crank ends bearing against the inner ends of the slots.

Having thus described my invention, what I claim is 1. Alamp-burner provided with a number of vertical rock-arms, an annulus movable on the burner, and means for connecting said annulus with the vertical rock-arms to cause the latter to rock on moving said annulus.

2. Alamp-burner provided with a plurality of chimney-holding arms, one of which at least is journaled to rock in the burner and has the lower end bent to form a crank and all having their upper ends bent or curved to form impinging offsets, an annulus held to the burner-body to partly revolve thereon and having a radial slot in which the crank end of said rock-arm rides, said annulus causing the latter to rock in its bearing and force form impinging oifsets adapted to impinge against the inner side of a chimney, and having their lower ends bent to form cranks, an annulus arranged to turn on the burner and having radial slots in which the crank ends of the rock-arms ride, said annulus on being turned in one direction causing the impinging offsets to swing outward beyond the deadcenter and the crank ends to move against one of the ends of the radial slots to check the further movement of the rock-arms, and on being swung in the other direction causing said impinging ends to swing inward to permit the lamp-chimney to be removed from or set onto the burner, substantially as set forth.

4. A lamp-burner provided with a plurality of vertically-disposed rock-arms having their upper ends bent or curved to form grippingoffsets designed to engage a chimney on the inner side thereof and having their lower ends offset to form cranks, and an annulus having radial slots with which the crank ends of the said rock-arms engage, said annulus being adapted to cause the upper ends of said rockarms to impinge against the inner side of a lamp-chimney to securely hold the same to the burner, substantially as set forth.

In testimony whereof I have affixed my signature in the presence of two subscribing witnesses.
