WlCK-ADJUSTER FOR CENTRAL-DRAFT LAMPS.
SPECIFICATION forming part of Letters Patent No. 564,018, dated July 14-, 1896.
v Application filedNovember 27, 1893. Serial No. 492,125. (No model.)
To all whom it may concern.-
Be it known that I, Nls JOHNSON,- of Meriden, in the county of New Haven and State of Connecticut, have invented a new Improvement in Wick-Adjusters for Central-Draft Lamps; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in
Figure 1, a view, partly in section and partly in side elevation, of a hanging lamp contain- .ing a wick-adjuster'constructed in accordance claims.
As shown in Fig. 1 of the drawings, my improvement is applied to ahanging lamp, and constructed so as to be operated from beneath the same, and comprises a draw-bar having an outer member A and an inner member A, a tubular operating-screw B, a bearing-tube C, and several adj unctive features, to be specified. The inner member A of the draw-bar plays up and down through a bearing D, located in the top D of the lamp fount E, the lower end of the said bar being connected with the wick-holder F, which may be of any approved construction, and which is designed to hold a wick G upon the central-draft tube H. The upper end of the said member A of the draw-bar is bent outward and screwthreaded to receive a coupling-head I, in the form of a ball, the said head being constructed upon its lower face with a socket I to receive the upper end of the outer member A of the bar, and furnished with a set-screw 12, by means of which the said member A is firmly connected with the coupling, and hence with the said member A. The bearing-tube C is secured at its upper and lower ends in the lamp-fount, and so that no oil enters it therefrom. It is furnished upon its inner face with a section C of a coarse screw-thread, which takes into a coarsely-pitched external thread B ,formed by indenting the operatingscrewB, the said thread extending, as shown, only a little below the center of the tube, the extreme lower end of which is sleeved over and soldered or'otherwise rigidly secured to the reduced portion J of the operating-nut J, by means of which the tube is rotated in one direction or the other.
The outer member A of the draw bar extends down through the upper end of the bearing-tube C, and down through the whole length of the operating-screw B, and also through the operating-nut J, projecting beyond the same, which is thereto provided with a central opening J The lower end of the said member A of the bar is furnished with a shoulder a, which bears upon a corresponding shoulder j, formed within the nut,whereby the said member A is prevented from downward movement through the nut. The projecting end of the said member is furnished with aknurled finger-piece K, separated from the outer face of the nut by a washer K.
Under the construction just described, the operating-screw and the outer member of the draw-bar are swiveled together at their lower ends, so that they are coupled together for longitudinal movement, although the nut and tube are left free to rotate together at the same time they are longitudinally moved.
It should be observed here that the pitch of the screw-threads is so coarse that the operating-screw rotates very readily, but still not freely enough so but what it frictionally holds the wick-adjuster in any position in which it may be left.
Having thus described my improved device, I will now proceed to set forth the method of its operation. Suppose, for instance, that it is desired to lower the wick by means of the screw. In that case the operating-nut would be grasped by the fingers and the screw rotated in the right direction for causing it to descend, as shown by broken lines. In its descent it carries the outer and hence the inner member of the draw-bar with it, whereby the wick is depressed. Then if the nut and hence the screw are turned in the opposite direction, the screw will be raised and the draw-bar with it. On the other hand,suppose that it is desired to raise and lower the wick from the under side of the lamp under the direct action of the bar. In that case the finger-piece will be grasped and the draw-bar drawn directly down, during which time the screw will follow it and rotate. Then if the draw-bar be raised by means of the finger-piece, the screw will retate in the opposite direction. So, too, if the upper end of either member of the draw-bar or their coupling is engaged and the drawbar pulled up and pushed down, in both of which. cases the screw will move with it, rotating in one direction or the other. The screw, however, will afford but little impediment to the direct operation of the draw-bar, inasmuch as it rotates in one direction or the other with very little friction.
The construction shown by Fig. 2 of the drawings illustrates my invention as applied to a table-lamp, or a lamp in which the wick is manipulated from the top of the fount. The broken lines of this drawing show the elevated position of the draw-bar, and thatthe operating-screw moves with it, and as this construction is on precisely the same princi ple as the construction shown in Fi g. 1, it is not necessary that it be further described.
If preferred, a projection upon the inner face of the bearing-tube might take the place of a section of a screw-thread, and the outer and inner members of the draw-bar might be made integral instead of independent and coupled together as shown.
It is apparent, therefore, that in carrying out my invention some changes from the special construction shown and described. may be resorted. to, and I would therefore have it 1111- derstood thatI do not limit myself to the exact construction herein shown and described, but hold myself at liberty to make such changes and. alterations as fairly fall within the spirit and scope of my invention.
I am aware, however, that wick-adjusting devices providing for the quick and fine adjustment of: the wick by means of direct plunging and lifting action of a draw-bar, and by means of the rotation of a finger-button and adapted to be opera-ted from the bottom or the top of a lamp-fount are old, and I do not, therefore, claim such a construction, broad l y.
Having fully described my invention, what I claim as new, and desire to secure by Let ters Patent, is
1. In a wick-adjuster for central-draft lamps, the combination with the fount and central draft-tube thereof, of a non-rotatable bearing-tube permanently mounted in the fount, a rotatable and longitudinally-movable operating-screw located within the said bearing-tube and having an external screw-thread coactin g with a thread or projection upon the inner surface thereof, a wick-holder applied to the cent a1 draft-tube of the lamp, and movable up and down thereon, and a draw-bar composed of an inner and an outer member, the upper ends of which are detaehably connected together, the said. inner member of the draw-bar being connected at its lower end with the wick-holder, and the said outer member thereof passing downward into the operating-screw, and having swivel connection. therewith, but no longitudinal movement independent thereof, substantially as set forth.
2. In a wickadjuster for centraldraft lamps, the combination with the fount, central draft-tube and wick-holder thereof, of a non-rotatable bearing-tube permanently mounted in the fount, a rotatable and longitudinally-movable operating-screw located within the said tube, and havin an external.
screw-thread which receives a thread or proj ection located upon the inner face thereof, an operating-nut applied to the lower end of the said screw, and having a central opening; a draw-bar composed of an inner and an outer member the projecting upper ends of which are detachably connected together, thesaid outer member of the draw-bar passing downward through the bearing-tube and screw, projecting below the lower ends. thereof and through the said nut, having swivel connection with the screw, but no longitudinal movement independent thereof, and the inner end of the said bar being connected at its lower end with the wick-holder; and a finger-piece formed independent of the outer member of the draw-bar, applied to the projectin lower end thereof, and bearing against the said operatingnut, substantially as described.
In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
