Fig. 1 is a front sectional view of an oil lamp according to one embodiment of the invention.

An oil lamp 10A includes an oil tank 50 for containing oil 26. Oil tank 50 includes an openable lid 44, for pouring oil into tank 50.

Oil tank 50 further includes a side outlet 54A.

Oil tank 50 further includes a vertically slideable piston 20A being sealed by a seal 22 to wall 52A of oil tank 50, for allowing the user to manually vertically slide piston 20A, for adjusting the top level of oil 26 to the level of height 24 of side outlet 54A. 264421/3 Oil lamp 10A further includes a horizontal pipe 30, communicating with tank outlet 54A.

A plurality of vertical pipes 34A, 34B, etc. extend upwards from top 62A of horizontal pipe 30, and communicate therewith. Vertical pipes 34A, 34B. etc. are not covered at the top.

Thus, oil level 24 is equal in tank 50 an in vertical pipes 34A, 34B, etc.

A movable cap 88A may close side outlet 54A, for not consuming oil contained in tank 50.

Preferably, tank outlet 54A communicates with the bottom 62B of horizontal pipe 30, or at least below the narrowing section of vertical pipes 34A, 34B etc., for allowing emptying pipe 30, for distinguishing the flames.

Horizontal pipe 30 further includes a horizontally slideable piston 20B being sealed to wall 52B horizontal pipe , for allowing the user to manually horizontally slide piston 20B, for not allowing oil 26 to enter vertical pipes selected by the user, such as 34D, 34E, etc.

Vertical pipes 34A, 34B, etc. are intended for inserting wicks 60 thereinto.

The term "candle" refers herein to a lighting unit, including oil and a wick.

Thus, oil lamp 10A provides the user with equal oil level, starting with height 54A, and lowering equally together. Oil 264421/3 lamp 10A further provides selecting the number candles, being 34A, 34B to be lighted. Oil lamp 10A further provides adjusting a constant starting level 54A of oil 26, for various amounts of oil 26 contained in tank 50.

The height of piston 20A may be adjusted by rotating a bolt 16, being threaded with a female thread of piston 20A.

The displacement of piston 20B may be adjusted by moving a handle 50, being magnetized with piston 20B.

Fig. 2 is a bottom view of the horizontal pipe of Fig. 1.

A handle 18B, being slideable within a track 48, allows the user to move piston 20B of Fig. 1.

Fig. 2 is a bottom view of the horizontal pipe of Fig. 1.

Fig. 3 is a side view of the horizontal pipe of Fig. 1.

Horizontal pipe 30 is disposed within a package 12.

A motor 74, being controlled by a controller 76 inputted by a level sensor 78, may rotate bolt 16, for providing top level 24 to oil 26.

According to one embodiment, controller 76 may rotate bolt 16, for providing top level 24 to oil 26 prior to lighting 264421/3 wicks 60, thus wicks 60 extinguish after a period determined by the physical sizes of the elements.

According to another embodiment, controller 76 may rotate bolt 16, for providing top level 24 to oil 26 incessantly.

This embodiment is advantaged of maintaining top level 24 of oil 26 to vertical pipes 34B and others, thus constant lighting thereto.

Track 48 explained for Fig. 1 may include a motorized wheel 64, for advancing a band 66, for sliding magnet 46, for sliding piston 20B of Fig. 4.

Controller 76 may operate motorized cog 64, for selecting the numbers of candles to be selected. The numbers of candles may be selected manually by a user interface 80 (Fig. 4) or automatically, such as being a function of the date, for serving Channuka lighting.

Thus, in one aspect, the invention is directed to an oil lamp (10A), including: - an oil tank (50), for containing oil (26), and including a side outlet (54A); - a horizontal pipe (30) communicating with the side outlet (54A) of the oil tank (50); and - a plurality of vertical pipes (34A, 34B) extending upwards from the top (62) of the horizontal pipe (30) and communicating therewith, 264421/3 thereby maintaining an equal oil level (24) to all of the vertical pipes (34A, 34B).

The oil lamp (10A) may further include• - a vertically slideable piston (20A) disposed within the oil tank (50), for constituting a bottom floor for the oil (26), thereby allowing sliding the vertically slideable piston (20A) for varying the oil level (24).

The oil lamp (10A) may further include• - a motor (74), for vertically sliding the vertically slideable piston (20A); - a level sensor (78) disposed in the oil tank (50), for sensing the oil level (24); and - a controller (76), being inputted by the level sensor (78), for operating the motor (74) to vary the oil level (24) to a predetermined level.

The oil lamp (10A) may further include• - a horizontally slideable piston (20B) disposed within the horizontal pipe (30), for not allowing the oil (26) to enter vertical pipes (34D) selected by the user of the vertical pipes (34A, 34B, 34D).

The oil lamp (10A) may further include: - a piston (20A, 20B) for controlling the oil (26), by sliding thereof via a handle (18A, 18B). 264421/3 The oil lamp (10A) may further include a thread (16), for sliding the piston (20A) by the handle (18A).

The oil lamp (10A) may further include a magnet (46), for sliding the piston (20B) by the handle (18B).

Each of the vertical pipes (34A, 34B) may include a narrowing section (86), for limiting a bottom disposition of a wick (60) contained in that vertical pipe (34A, 34B), thereby allowing extinguishing flames of the vertical pipes (34A, 34B) by the varying of the oil level (24) to below the narrowing section (86).

The oil lamp (10A) may further include• a movable cap (88A), for closing the side outlet (54A), thereby allowing not consuming oil contained in the tank (50).

According to one embodiment, shown in Fig. 1, the communication (58) of the horizontal pipe (30) with the side outlet (54A) of the oil tank (50) is below a selected height of the vertical pipes (34A, 34B), for allowing removing the oil (26) from the vertical pipes (34A, 34B) into the oil tank (50).

According to another embodiment, shown in Fig. 4, the communication of the horizontal pipe (30) with the side outlet (54A) of the oil tank (50) is above a selected height of the vertical pipes (34A, 34B), for not consuming oil (26) from the tank (50) below that height. 264421/3 A potential advantage of the self-filling menorah is that all the oil lamps may be simultaneously extinguished which generally is not possible with candle־based menorahs where some candles remain lit while others burn themselves out.

That is, in the self-filling menorah, all wicks have the same length and therefore burn at the same rate.

From a religious aspect, a menorah which may be filled with exactly 44 cups of oil may be used to represent the miracle of Hanukkah where a small container of oil lasted for the eight days of Hanukkah.

Further, there is no need to purchase oil cups, which are also significantly more expensive than oil, and the handling of them is dirty. Further, turning off the candles / firecrackers is done almost at the same time, due to the law of the communicated vessels principle.

An oil lamp 10B according to another embodiment, includes an oil tank 50 for containing oil 26. Oil tank includes an openable lid 44, for pouring oil into tank 50.

Oil tank 50 includes a bottom outlet 54B, from which extends a pipe 88A downwards, and from then upwards above the top of tank 50.

Upon filling tank 50 only, the oil level does not exceed the top of tank 50. /9/22 264421/3 Fig. 7 is a front view of the oil lamp of Fig. 6 upon a first operation of its syringe.

A syringe 94 is disposed along pipe 88A, such that cylinder 90 of syringe 94 includes an inlet 96A and an outlet 96B. Each press on a piston 92 of syringe 94 presses oil further upwards along pipe 88A above the top of tank 50.

A one-way valve 89A avoids return from pipe 88A to tank 50.

A horizontal channel 102 extends horizontally from the top 104A of pipe 88A.

Cups 106A, 106B, etc. communicate with channel 1 and extend therebelow.

Each press of piston 92 is sized to dispense one dose being the content of one cup.

Thus, from the state of Fig. 7 that oil has been lifted to the top 104A of pipe 88A, a first press on piston 92 fills cup 106A only.

A second press on piston 92 attempts to fill cup 106A twice. Since cup 106A is already full, the surplus oil flows from /9/22 20/9/22 264421/3 cup 106A towards cup 106B, thus both cups 106A and 106B are filled.

Channel 102 may be closed at the top thereof between the cups.

Thus, according to another embodiment, the invention is directed to an oil lamp (10B), including - an oil tank (50), for containing oil (26), and including an outlet (54B); - a first pipe (88A); - an oil dispenser (94), for receiving the oil (26) from the tank outlet (54B), for dispensing thereof into the first pipe (88A); and - a horizontal channel (102), first end (105A) thereof extending from a top (104A) of the first pipe (88A); - at least first (106A) and second (106B) cups, each communicating with the horizontal channel (102), extending therebelow, and being disposed one (106B) after the other (106A) along the horizontal channel (102), thereby the oil dispensing into the first pipe (88A) dispenses the oil to the second cup(106B) only upon filling the first cup (106A). /9/22 The oil lamp (10B) may further include• 264421/3 - a second pipe (88B), top (10B) thereof extending from a second end (105B) of the horizontal channel (102), and bottom thereof extending to an inlet of the oil tank (50).

The first pipe (88A) may include a one-way valve (89A), for allowing the dispensing thereinto only.
