MAX VON RECKLINGHAUSEN, OF NEW YORK, N. Y., ASSIGNOR, BY MESNE ASSIGNMENTS, TO COOPER HEWITT ELECTRIC COMPANY, A CORPORA- TION OF NEW YORK.
GAS OR VAPOR LAMP AND APPARATUS CONNECTED THEREWITH.
SPECIFICATION forming part of Letters Patent No. 750,890, dated February 2, 1904.
Application filed March 27, 1902.
To all whom it may concern.-
Be it known that I, MAX VON RECKLING- HAUSEN, a subject of His Majesty the Emperor of Germany, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Gas or Vapor Lamps and Apparatus Connected Therewith, of which the following is a specification.
In operating gas or vapor electric lamps of the Cooper Hewitt type it has been found that difficulty sometimes arises in starting and running such lamps when they are exposed to cold air or drafts, as when they are located outside a building in winter weather. It has heretofore been proposed to mount such lamps in what may be called lanterns, wherein the tube containing the gas or vapor adapted to become luminous is protected from exposure to the atmosphere by being surrounded by a transparent protecting-tube within which the luminous tube is supported. I have devised means whereby the admission of the external air into the body of such a lantern and its passage therethrough shall be controllable either manually or automatically, as will be fully explained in the specification which follows. Moreover, to provide against extreme conditions even under such surroundings I may provide special means for heating the interior of the lantern and thus raising the temperature of the luminous tube until it is in a condition suitable for easy starting and operation. When an automatic air-admission device is employed, it may be operated by means of an electromagnet or solenoid in series with the lamp.
The apparatus which the magnet or solenoid may operate may be a slide which in one position will close the lower end of the lantern and in another position will leave a free passage of considerable area for the outer air. As the lamp will take a great deal of current in cold weather the action of the series magnet may be made to keep the slide closed, while in warm weather, when the lamp will take less current, the slide will be kept wholly Serial No. 100,167. (No model.)
or partially open by means of a spring or other device acting against the pull of the magnet. Another way to govern the slide is by means of a thermal spring acting according to the lantern temperature to keep the slide in a closed or open or intermediate position, as the case may be.
I have illustrated my invention in the accompanying drawings, in which Figure 1 is a vertical section of my lantern. Fig. 2 is an enlarged vertical section thereof, showing the parts in greater detail. Fig. 3 is a section of the upper'part of the lantern, taken at right angles to the section shown in Fig. 2. Fig. 4 is a cross-section along the lines 4 4. in Fig. 3 looking downward. Fig. 5 is a vertical section along the line 5 5 in Fig. 2 looking toward the left. Fig. 6 is a cross-section along the line 6 6 in Fig. 2 looking downward. Fig. 7 is a similar sectional view along the line 7 7 in Fig. 2. Fig. 8 is a detail view. Fig. 9 is a detail of a solenoid apparatus adapted to operate the air-admission slide automatically. Fig. 10 is a vertical section along the line 10 10 in Fig. 9, and Fig. 11 is a view of an automatic thermal device adapted to operate the air-admission slides.
In the drawings, 1 is a gas or vapor electric lamp of the type known as the Cooper Hewitt lamp. The lamp is provided with a positive electrode 2, which may be of pure iron, and with a negative electrode 5, of mercury. The lamp thus described is surrounded by a transparent tube 3-say of glass-the lower end of which is supported on an insulatingbase 4, which is itself mounted upon a plate 6, as shown. Above the tube 3 is another plate 7, which is connected to the plate 6 by rods 8 8, the plates 6 and 7 and the rods 8 constituting the framework of my lantern.
Forks 9 9, secured to the plate 7 by nuts 10 10, embrace the upper end of the tube 3 and constitute a sufiicient support therefor.
' The stems of the forks 9 9 are, as clearly shown in Fig. 4, located in slotted openings, whereby the adjustment of the transparent in Fig. 8. In that figure a notched lever 16 is pivoted to the plate 6 and may be made to assume different positions by moving it upon its pivot.
' set into the notch in the lever 16, the latter may then be moved into theposition illustrated in Fig. 6, and a set-screw 17 may then be tightened against the handle 15 of the loop 14, whereupon the loop will be centered with respect to the lantern-frame and the tube 3. It is then adapted to receive the lower end of the lamp 1 and hold it centrally within the tube 3, as is desired.
The plate 7 is provided with openings 18 18, corresponding to openings 19 19 in an adjustable open-ring plate 20, secured by clips 21 under the plate 7. The ring-plate 20 can be moved so as to make the openings 19 mesh with the openings 18 either wholly or partially, or it can be still farther moved to the position illustrated in Fig. 4, so that the openings referred to are out of mesh. The object of this part of the structure is to provide for the passage of air into the region above the plate 7 through the openings 18 19 or to shut off the passage through such openings, as may be required.
The upper part of the lantern consists of a metallic shield 22 and an adjustable hood 23. The former is hinged to the plate 7 by means of brackets 24 24, cooperating through pivots 25 25 with a yoke 26. The said yoke 26 is secured by a nut 28 to the lower end of a bolt 29, provided at the top with an opening 30, whereby it can be attached to a suitable support. An externally-screw-threaded nut 31 surrounds the bolt 29 and has secured to it by screws or rivets a number of arms 27 27, forming a spider, these arms being secured at their opposite ends to the shield 22, as shown. The nut 31 is adapted to receive a nut 32, formed on or secured to the hood 23.
The structure composed of the hood 23, the nuts 32 and 31, the spider 27, and the shield 22 can be lifted off the bolt 29 at will. The yoke 26 can then be tilted upon the pivots 25 25 far enough to permit the lamp 1 to be thrust down through the openings 12 and 13 for adjustment within the lantern.
The hood 23 has two diameters, as shown, and is capable of being carried down far enough to entirely close the opening between the upper part of the shield 22 and the lower part The handle of the loop 14 being,
of that portion of the hood 23 having the smaller diameter. In this way the passage of air out at the top of the shield 22 can be prevented, if desired, or an opening can be left there for the circulation of air.
In order to fix the parts in place after the lamp has been put into the lantern, I provide a tilting yoke 33, pivoted at 34 on one of the brackets 24 and adapted to move down into the position illustrated in full lines in Figs. 3 and 4, so as to hold the yoke 26 from swinging on its pivots 25.
The lower part of the lantern consists externally of a box 35, hinged at 36 and provided with a detent 37 for engagement with a catch 38, whereby the box portion can be held up in the position illustrated in Fig. 2 or can be swung away to give access to the parts within the box. The lower plate of the box is centrally perforated, and an insulating ring or bead 39 is set in, the said ring or bead being outwardly curved and adapted to serve as a bearing for a slide 40, provided with a handle 41.
The bottom plate of the box is immediately above the slide 40 and is provided with openings 42 42, corresponding in shape to the shape of the slide 40. In other words, the slide is formed in wings or on opposite sides of the center, each ring representing substantially a quadrant adapted to cover the quadrant-shaped openings in the bottom plate of the box 35. Thus when the slide is in one position the bottom of the box is practically closed, While in another position about half the bottom of the box is open to admit air.
In Fig. 7 the slide is represented in an intermediate position, showing the openings only partially closed. The manipulation of the slides in this instance may be accomplished through the medium of the handle 41.
In Figs. 9 and 10 I show automatic means for operating the slide, such means consisting of a curved solenoid 44, having a properlyshaped armature 45, the solenoid itself being supported upon a bracket 46, attached to the inner wall of the box 35, while the armature is attached to one wing of the slide 40, being operated upon by a spring 47 in such a manner as to hold the slide open, except when the solenoid is acting against the force of the spring.
It will be understood that the solenoid is arranged in circuit with the lamp, so that when the lamp takes current the solenoid Will be energized more or less strongly, according to the amount of current passing through the lamp-circuit. In cold weather the lamp takes considerable current, and the tendency of the solenoid will then be to close the solenoid in opposition to the force of the spring 47. The same tendency will exist in warm weather, but to a less degree, owing to the fact that the lamp-circuit carries less current under such conditions. Accordingly the slide will be operated more or less, or not at all, according to the temperature conditions under which the lamp operates.
In Fig. 11 the force acting upon the slide is that of a thermal spring 50 of any of the well-known designs, consisting generally of It remains to describe the circuit connections and the means which I have devised for supplying artificial heat to the bottom of the lantern so as to be independent of external temperature conditions.
Referring to Figs. 2 and 5, it will be seen that an electric heater is shown at 51, the same being mounted upon an insulating-bracket 52, secured to the plate 6. This heater may be of any preferred construction. For example, it may consist of fine platinum wire wound upon supports of porcelain or other good heatresisting non-conducting material,the wire being of such diameter as to become highly heated under the influence of the current passing through it. The current supplying the heaters is preferably independent of the current supplying the lamps and may be derived from any suitable source. The wires leading to the heater and thus leading to the lamp generally enter through the ring or head 39, the latter wires being led to binding-posts 55 56 on an insulatingbracket 57 secured to the plate 6. The binding-screws of these bindingposts are connected one to the upper electrode of the lamp through the wire 60 and the other to the lower terminal thereof through the wire 61. The egress of air through the top of the lantern may be controlled by means of the slide 20 and by the adjustment of the hood 23, it being understood that there is always an opening above the top of the glass cylinder 3, as shown. On the other hand, the ingress of air to the bottom of the lantern is controlled by means of the slide 40 and the openings 42 42. By various adjustments of the parts named the ventilation of the lantern is governed.
What I claim as my invention is 1. The combination with a gas or vapor electric lamp, of an inclosing lantern-frame supporting a transparent tube or cylinder outside the lamp, and adjustable means for centering the lamp within the said tube or cylinder.
having an opening near its top, a transparent tube or cylinder outside the lamp and supported by the said frame, means for adjusting the top of the said tube or cylinder concentrically with the said opening, andmeans for centering the opposite end of the lamp within the said tube or cylinder.
4:. The combination with a gas or vapor electric lamp, of a lantern supporting and surrounding the same, and separate means for regulating the admission and exit of air to and from the said lantern.
5. The combination with a gas or vapor electric lamp, of a lantern supporting and surrounding the same, a protecting device for the upper end of the lamp, a hood above the lamp, and means for adjusting the said hood.
6. The combination with a gas or vapor electric lamp, of a lantern supporting and surrounding the same, a metallic box or casing at the end of the lamp containing the negative electrode, and means for regulating the admission of air into the said box or casing.
7. The combination with a gas or vapor electric lamp, of a lantern supporting and surrounding the same, and automatic meansfor regulating the admission of air to the lantern.
8. The combination with a gas or vapor electric lamp and a lantern supporting and surrounding the same, of adjustable devices for regulating the admission of air to the lantern, and independent adjustable devices for regulating the exit of air therefrom.
9. The combination with a gas or vapor electric lamp and a lantern supporting and surrounding the same of circuit-terminals for the lamp mounted within the lantern, an electric heater also mounted within the lantern, the circuit-terminals and the heater being inclosed within a suitable box, and means for withdrawing the box so as to gain access to the heater and the terminals.
