JOHN C. MILLER, OF TORRINGTON, CONNECTICUT, ASSIGNOR TO THE MILLER MANUFACTURING COMPANY, OF SAME PLACE.

WlCK-ADJUSTING DEVICE FOR LAM PS.

SPECIFICATION forming part of Letters Patent No. 613,458, dated November 1, 1898.

Application filed April 11, 1 8 9 8 To all whom, it may concern:

Be it known that I, JOHN C. MILLER, of Torrington, in the county of Litchfield and State of Connecticut, have invented a new Improven cut in Wick-Adj usting Devices for Central- Draft Lamps; and I do hereby declare the following, when taken in connection with the accompanyin g 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 plan and partlyin section, of a lamp-fount containing one form that my improved wick-adjusting device may assume; Fig. 2, a broken plan view of the said lamp, showing the means for operating the draw-bar; Fig. 3, a view in transverse section on the line a b of Fig. 1 and showing the means for connecting the draw-bar with the wick-band of the wick-carrier.

My invention relates to an improvement in wick-adjusting devices for central-draft lamps, the object being to provide a simple, convenient, and durable construction, composed of few parts, not liable to derangement, and permitting the draw-bar to be located and operated in an inclined position with its upper end well away from the neck of the fount.

, With these ends in View my invention consists in certain details of construction and combination of parts, as will be hereinafter described, and pointed out in the claims.

In carrying out my invention as herein shown I employ a straight rigid draw-bar A, placed in an inclined position and movable downward and inward and upward and outward with respect to the draft-tube B, which is located in the center of the fount B, the top B of which is provided with an inclined tube C, formed upon its outer face with a bearing-tube C, in which the said draw-bar has bearing and in which it moves up and down. Upon its inner face the said draw-bar is formed with a rack A, which is meshed into by a pinion D, located within the tube C, which is capped by a cap or cover C and which I shall, for convenience of identification, hereinafter call the pinion-tube.

The said pinion D is mounted upon a shaft E, the opposite ends of which have bearing in Serial No. 677,210. (No model.)

the said pinion-tube and the projecting ends of which are furnished with operating-buttons F F, which bear upon opposite sides of the tube. Under'this construction the shaft E has hearing at points so far apart that it is very stably supported, while the provision of its opposite ends with operating buttons greatly facilitates the convenience of operating the adjusting device, for it will be readily understood that by turning either button the draw-bar may be raised or lowered. For

bar it is also provided at its upper end with the knob or button A by means of which it is grasped for plunging or thrusting it downward and for lifting or drawing it upward, at which time the pinion D, shaft E, and operating-buttons F F rotate idly in one direction orthe other. To this end the rack A of the bar and the teeth of the pinion are cut so as to work with sufficient freedom to permit the bar to be worked on the plunge-and-lift plan as well as on the rack-and-pinion plan.

On account of supporting the draw-bar in an inclined position its lower end approaches the draft-tube B when the draw-bar is pushed downward into the fount B and moves away from the said draft-tube when the draw-bar is lifted in the said fount. This peculiarity in the operation of an inclined draw-bar must be provided for in the connection of the lower end of the draw-bar A with the wick-carrier, which consists, as shown, of a band or sleeve G, provided with integral spring wick-gripping fingers G' and adapted in size not only to ride up and down upon the draft-tube B, but also to be rotated or oscillated thereupon. As herein shown, I employ for the connection of the lower end of the draw-bar A with the wick-band G a coupler H, consisting of a longitudinally-bowed rod or bar having its outer and lower end flattened to form a tongue H, which contains a vertical opening H receiv= ing the lower end of the draw-bar, which is upset, as at A so as to pivotally connect it with the said coupler, which is free to turn upon the lower end of the bar. The inner and upper end of the coupler is reduced in diameter to form a bearing H which stands in a plane at a right angle to the plane of the tongue H at the other end of the coupler and the purpose of raising and lowering the drawred which has bearing in the folded central portion of a sheet-metal strap I, located upon the lower end of the wick-band G. The said bearing 11 extends upward through the strap and is provided with a tran sversely-arran ged cou pling-pin I, which rides upon the upper edge of the strap. I do not, however, limit myself to employing such a wick-carrier as shown, nor to employing the means shown and described for connecting the wick-carrier with the lower end of the draw-bar, for it is obvious that some other vertically-movable and oscillating wick-carrier may be employed and that some other means for connecting such a carrier with the lower end of the draw-bar may be devised. It is apparent, also, that other ways might be resorted to for pivotally connecting the ends of the coupler with the draw-bar and wick-carrier.

It will be readily understood from the foregoing description that when the draw-bar moves upward and outward the wick-band will not only be lifted upon the draft-tube, but also rotated thereupon in the direction of the draw-bar, while on the other hand when the draw-bar is moved downward and inward the wick-carrier will not only be moved downward upon the draft-tube, but also rotated thereupon in the direction away from the draw-bar. It will also be understood that this oscillating or rotatable movement of the wick-carrier is directly proportional to the inward and outward movement of the draw-bar due to operating it in an inclined position.

In view of the modifications suggested and of others which may obviously be made I would have it understood that I do not limit myself to the exact construction 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.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a central-draft lamp, the combination with the fount thereof, of an independentlyformed pinion-tube mounted in the top of the said fount and provided with an offsetting bearing-tube, a pinion located within the said pinion-tube, a pinion-shaft passing transversely through the pinion-tube and having hearing at its ends therein, operating-b uttons applied to the projecting ends of the shaft, a draw-bar having a rack formed upon it, located within the bearing-tube which opens into the pinion-tube to permit the pinion to mesh into its rack, a cap applied to the top of the pinion-tube for closing the same, but not closing the bearing-tube, through the upper end of which the draw-bar projects, a wick-carrier, and means connecting the lower end of the draw-bar with the said carrier.

2. In a central-draft lamp, the combination with the fount thereof, of a draw-bar located in an inclined position in the said fount and moving inward and downward and outward and upward, a vertically-movable and oscillating wick-carrier mounted upon the central draft-tube of the lamp, and means connecting the lower end of the draw-bar with the said band which rotates toward the bar as the same is moved upward and outward and away from the bar as the same is moved downward and inward.

3. In a central-draft lamp, the combination with the fount and central draft-tube thereof, of a wick-carrier vertically and rotatably movable upon the said draft-tube, a draw-bar mounted in an inclined position in the fount and movable downward and inward, and upward and outward, and a coupler adapted at its outer end to be connected with the lower end of the draw-bar and at its upper end to be connected with the wick-carrier.

4. In a central-draft lamp, the combination with the fount and central draft-tube thereof of a wick-carrier mounted upon the said drafttube so as to be vertically and rotatably movable thereupon, a draw-bar mounted in an inclined position in the fount and movable downward and inward and upward and outward, and a longitudinally-bowed coupler pivotally connected at its lower and outer end with the lower end of the draw-bar and pivotally connected at its inner and upper end with the wick-carrier.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

JOHN C. MILLER.
