Lamp.

Patented in the German Empire on May 4, 1886.

The present invention relates to lamps, and more particularly to those below Construction known as vacuum lamps. Some of the ones described below Improvements can also be applied to those lamps where the inflow of the oil or liquid fuel to the burner in other ways than through a Vacuum is regulated.

The invention aims to produce a simple, safe, durable, effective one and automatic shut-off of the oil drain from the reservoir at the moment in which the inlet opening for supplying the lamp is opened, and prevents the supply and drain openings of the oil container are opened at the same time. For this purpose is the Cover of the reservoir provided with a closure device through which the bottom to descriptive valves are put into action and the lid in its position the oil container is held until the valve that regulates the outflow opening, is tightly closed. Every handling or accidental adjustment is due to the construction of the valves before the cover is properly put on, excluded.

The construction of the burner is with regard to the air supply to the flame and on the supply of oil or liquid fuel significantly improved, and that Overflow in or on the main pipes and in the case of the wick screw pin is prevented. The innovation also relates to the device for raising and lowering the Wicks, on the fastening of the lamp glass, on the construction and the arrangement of the Drip tray and a simple, handy and durable removable lampshade. The temporary flicker of the flame, for whatever reason the same may occur, as much as possible is prevented, and the construction creates an apparatus with it A large, bright and constant flame achieved with moderate fuel consumption; the individual parts of the apparatus are easily accessible so that handling, filling, Lighting, transporting and fixing the lamps can be done easily.

A is a container, which is preferably made of glass or some other transparent or translucent material so that the level of the oil it contains can be easily seen. The tubes B and B ¹ and the ring C form the line of the oil from the reservoir A to the burners, and through this part of the container and the burner, together with the side parts by means of screw to the carrier, or the stator attached. In the lower part of the container a cross piece D is attached, which is provided with a valve seat α and a sleeve for receiving the oil drain pipe B and a sleeve for receiving the air supply pipe b . The air supply pipe b extends close to the upper end of the oil reservoir. The crosspiece D and the tube B are soldered at their junction to the metal bottom of the reservoir so that they serve as a support for the latter and make the internal valve arrangement completely safe. The valve which regulates the oil discharge from the reservoir is designed in the form of a cylinder c , which is closed at its upper end by a slightly concave plate in order to offer the valve spindle d a proper seat and support point. A small opening is made in this valve at e, which is closed as soon as the valve is pressed deep enough into its seat; as soon as this occurs, but the valve even when asleep f the Oelabflufs to the pipe B, thus preventing the Abfiufs of the oil from the reservoir through a double manner. On the upper part of the valve spindle d sits the valve g with a leather or other oil-tight packing. It is so constructed that it presses firmly against the edge of the feed opening and completely prevents the inflow of air as long as it is not opened. A spring h inserted into the hollow valve c and its hollow seat. causes the lower valve to be kept open and the upper valve closed until both valves are adjusted.

The neck i attached to the attachment k forms a filling funnel, at the lower end of which there is the opening regulated by the valve g. This neck is advantageously made of glass, so that the rise of the oil in the reservoir can be observed through it and an overfilling is prevented; but it can also naturally be made of metal.

The valve spindle d penetrates through this funnel in which the closure housing / is located; the latter has openings in its lower part for the free flow of the oil. The upper open part of the funnel i is closed by a cover E , which can be removed so that oil can be admitted into the reservoir, which must then pass through the opening regulated by the valve g. The valve g cannot be lifted from its seat until the cover E has been removed, and the cover E is connected to the other parts by a lock in such a way that it cannot be removed until the valve rod is depressed deep enough to allow the valve rod to be removed lower valve to close. The lock part or key m is attached to the cover E , which has grooves into which the ends of the lock housing insert when the lock part m with the cover is turned into a certain position before which the key cannot be removed from the housing.

The upper end of the housing is shown in Figure 4; the shape of this part can be varied many times without changing the essence of the invention. The closure is formed from two main parts η and 0, of which one part η rests on the upper end of the valve spindle and has projecting ribs or springs which can rise and fall in the edge grooves of the housing; one of these grooves is shown at q, FIG. 3; the same prevents turning of the part n. The other part 0 is turned by the locking piece m .

If the part η is pressed down, the valve spindle is moved in such a way that it regulates the valves. When the Verschlufstheil is used m, a reciprocating or turning jobs of the cover is that part 0 also move, and the inclined surface of the part is ο because they overall on the lower correspondirenden

. The inclined part presses down the lower closing part η and hold it down in spite of the upward force of the spring h , while the two flat surfaces assume the positions shown in FIGS. 6 and 11.

In this position the lower valve is closed, the upper one opened and the lid E can be removed so that oil can be poured into the container A. Since the Verschlufs without a key or Verschlufstheil m can not be moved, so the valves can not be adjusted before the lid is put back on and the lamp in gehörigem state is. When the reservoir is full, the lid is put on and given a little twist. As soon as the flat surfaces of the closure have slid past each other, the spring h will push the valve spindle upwards, whereby the lower valve is opened, the upper one is closed and the lid is fixed in its place. Is this the tubes B and B ¹ passivated Rende oil burned, b air in the upper part passes through the tube a of the reservoir, as a result of the Oelzuflufs begins anew and the food is carried out of the burner constant. Without this admission of air, constant feeding cannot occur, since the oil would be retained as a result of the complete vacuum arising in the upper part of the reservoir A or the dilution of the air.

On the hollow ring C is a tube G ¹ , to the lower part of which the collar C ² is fastened in such a way that one part can rotate in the other, by inserting the ring, as in c ¹ , into one on the lower part of the Rohres C ¹ attached groove or recess is bent or bulged. A projection is attached to the pipe collar C ² , through which a pin or an adjusting screw C ⁴ passes, which presses against the carrier or stand. The screw can hold the lamp on the stand at any height, and because of the special arrangement between the ball and the tube, the lamp can be rotated around the stand. When the lamp is moved up and down, the screw goes with it and is therefore always in the appropriate place for use.

In Fig. Ι a stand with a wide base C ^{5 is} shown, as such is suitable for table or floor lamps; the base is made of cast iron and the iron rod C ^{6 is} screwed into the same. A cover made of bronze or other suitable material is attached over the lamp base and a tube C made of the same or different material is attached over the rod, in order to give the lamp a nice appearance. The cladding tube is ^{attached by an eyelet C 8} which is screwed to the upper end of the rod C ⁶ and serves as a support ring for the lamp.

F is the burner's oil container. It is usually made of glass or some other transparent or translucent material, so that the flow of oil can easily be observed. F ¹ is the central air tube around which the wick rises. The drip tray F ² on the lower part of the burner is shaped so that it springs up onto the metal end piece F ^{3 of} the oil container, from where it can be easily removed. The drip tray has a perforated cover plate F ⁴ and a perforated part f ¹ through which air can reach the central tube F ¹ , the air flow being regulated in such a way that the flame does not flicker. On the upper part of the drip-tray a removable perforated plate F ^{5 is} attached, the middle part of which, as can be seen in the figure, is bent open. When the drip tray is removed, the plate F ⁵ can easily be removed and cleaned of burned wick parts etc. which have accumulated on it; the plate serves to regulate and distribute the incoming air and to keep the air ducts in the lower part of the burner clear of all blockages and free for air inflow. The direction of the air flow is indicated in FIG. 14 by the arrows.

Around the lower part of the central air pipe F ¹ is a second pipe G; which around the former forms an annular space into which the lower end of the wick protrudes and into which oil from the container F flows through the small openings g ^l . At the upper end of the tube there is a larger chamber G ¹ with which the tube B ¹ communicates; From this chamber the oil finds its way through a small opening g · ² into the container F. Outside the chamber G ¹ the oil container is closed at the top, Fig. 14, and no air can enter the chamber G ¹ from where from it reaches the space above the oil in container A before the oil has sunk below the level of opening g ¹ ; If this occurs, the air passes through the small tube H into the chamber G ¹ . The purpose of the chamber G ¹ is to contain an oil supply from which the oil container F can be fed, which is always large enough to prevent the air from suddenly entering the tube B ¹ when the lamp tips over; also the chamber G ^{1 can} never be emptied too quickly, since the opening g · ^{2 is} very small in relation to the size of the chamber.

To get a good connection between the chamber G ¹ and the pipe B ¹ ,

the former is cut out according to the shape of the pipe and the latter is soldered to the former; the end of the tube B ¹ is closed by the cap B ² and a small opening is made in the lower end of the cap, through which the connection with the chamber G ¹ is established. The pipe B ¹ is also soldered to the metal cylinder / at its connection point and the two connections hold the burner firmly and robustly on the pipe jB ¹ . The pipes F ¹ and G are soldered at the points where they reach the lower part of the oil container, and the pipe G extends down to the metal plate F ³ above the drip tray, where it is also soldered, and so are these two parts F ¹ and F 3 F ³ holds in place and secures the inner tubes solidly and securely.

On the outside of the flame, the air passes through the perforated plates KK ¹ K ² , which are arranged inside and outside the transparent cone L. The plates M and M ¹ are full and form a channel between them, through which air flows down through the tube H to regulate the supply of the lamp. The wick cap N, which can be made of glass or other suitable material, rests inside M , and the oil, which drips out over the wick cap, flows between the channel M and M ¹ and through the tube H into the oil container. This will keep the outside of the lamp dry. The interior of the tube F ¹ is also kept clean and dry by arranging a cylindrical socket N ¹ , between which and the tube a space is formed which communicates below with the space in which the wick is located, so that a space is formed Dripping of the oil into the interior of the pipe F ^{1 is} prevented. The upper end of the air tube is provided with ribs, as shown at f- , and the tube N ¹ is fixed in its position by firmly adjoining these ribs, leaving a sufficient gap between F ¹ and N ¹ for the oil to flow through .

The upper part of the burner, including the plates KK ¹ K ² , and the cone L are at the same time detachable, in order to facilitate lighting and cleaning. O is an upright cylinder which forms the lamp glass holder or the seat for the lamp cylinder. ^{Sleeves O 1} for receiving the arms of the lampshade are attached to the cylinder O in matching spaces, FIGS. 1 and 16. The arms, which are labeled Q., are made of metal and their ends fill the sleeves or eyelets O ¹ completely and are shaped according to the circumference of the cylinder O , so that they find a firm and sturdy support in their seats, from which they can be removed if necessary. The screen R has one of the usual shapes and rests on the arms Q., from which it can be lifted by turning one of the same.

Since the space above the oil in the reservoir F has no other connection with the outside air than the long and narrow tube H, there can be no counter-draft through the lamp cylinder, as is often used to extinguish the lamp, and therefore no precipitating flame the oil or the gases contained in the container above it. The wick screw shaft 5 passes through the cylinder I , FIG. 9, and is provided with tubes S ¹ and S ² , the latter of which is closed at its outer end. These tubes fit snugly onto the shaft, forming sleeves in which it can be rotated, preventing oil from escaping along the shaft. The cogwheels S ³ , which press against the wick, are attached twice, as shown, ie they each consist of two toothed disks so that they clamp the wick tightly and it cannot slip out. The teeth of one disc are so shaped that they alternate with those of the other, the tips of the teeth not being so sharp as to cut into the wick. The tube F ¹ is toothed on the side opposite the wheels so that the wheels press the wick into the toothing and thereby form a firm hold and ensure that the wick moves up and down evenly on the wick tube.

The cone L can easily be lifted from its seat, which is connected to the ring holding the lamp glass, so that while the burner attachment is removed, the cone can be removed for cleaning or replacement. The lamp constructed in the manner described produces a large, luminous, and steady flame.
