OTTO SCHULZE in STRASBOURG (Alsace). Innovation in electric lamps.

Patented in the German Empire on January 15, 1881.

The present innovations relate to the peculiar production and regulation the electric arc, as well as the automatic shutdown of the lamp.

The basic idea is to remove the carbon rods from each other to make the electric Arc automatically through the corresponding effect of the dead weight of one or more iron cores, i.e. regardless of the current strength, the regulation of the arc, however, by the electromagnetic Effect of one or more of the number of iron cores used, between to effect both carbon rods of switched wire coils on the aforementioned iron cores.

This idea can be applied in the most varied of ways, be it with lamps that move one or both carbon rods, guiding them against each other in a straight line or at an angle, also with carbon guides by lever, rack or chain.

In the accompanying drawing, FIG. 1 shows the coal guide by chain, with application only an iron core and a wire coil, however indicated in Fig. 3 by a rack with omission of all insignificant details.

As can be seen from Fig. 1, the chain wheel of the coal guide, which the latter is assumed to be known, is connected to the climbing gear A by a lock on the same axis, and the upper coal holder is raised by turning the climbing wheel to the right, or the upper coal holder is lowered by its own gravity, if there is no inhibition on the climbing wheel, until it finds a support point on the lower carbon rod or on the stop pin α attached to the one sliding rod when it descends.

A lever F with tooth x, which is movably mounted outside the steering wheel pivot point, engages in the climbing wheel A, the latter falling into the teeth of the climbing wheel from the position ο of the lever.

The weight of the lever F is measured in such a way that the corresponding rotation of the climbing wheel is not completely inhibited when the upper coal holder moves downwards, but is only slowed down by alternately disengaging and engaging the tooth χ in the teeth of the climbing wheel in position ο '.

Above the steering wheel is the double lever B , movable in the pin, with the movably attached iron core C, the fork E and the driving rod H, and finally the adjustable counterweight G.

The upper part of the iron core C protrudes into the coil D, which is wound with a short, thick and a long, thin copper wire. is.

When the iron core is in the raised position, the drive rod H closes the Contact J.

The circuitry of the individual parts of the lamp can be seen in FIG.

The excess weight of the double lever B is regulated to the side with the iron core in such a way that the effect of this excess weight on a pin attached to the side of the lever F by means of the fork E rotates the steering wheel to the right and thus the upper coal holder is lifted and the carbon rods are removed from each other .

The contact J is closed when the iron core C respectively. the fork E is lifted so high that the lever F can move a little over position ο unhindered.

The fork E , which is movably attached to the double lever B in pins, has the purpose of establishing the connection with the latter when the excess weight of the double lever acts on the lever F.

When the lamp is put into operation, pulling on the free end of the chain makes the upper one Coal holder lifted so high that after inserting the two carbon rods there is between them there is still a gap between the two facing ends.

If a corresponding electric current now enters the lamp through the supply terminals, Fig. 2, the entire electric current first makes its way through the thin wire of the coil, since the carbon rods are separated from each other and Contact J is open. As a result, iron core C is drawn into the coil respectively. lifted up and switched on by the closing of the contact J the secondary loop of thick wire wound on the same coil, whereby the greater part of the current circulates through this secondary loop and by its electromagnetic effect keeps the iron core protruding into it in the raised position.

Since lever F now relieves the load, the climbing wheel can follow the downward movement of the upper carbon holder until both carbon rods meet.

By branching the electric current over the carbon rods, the electromagnetic force of the shunt on the iron core is weakened in such a way that the weight of the iron core is greater than this, as a result of which the iron core sinks and contact J opens or. turns off the bypass. Furthermore, the lever F is loaded and the climbing wheel is rotated accordingly, which, as already described above, results in the removal of the carbon rods and the creation of the arc.

The distance between the carbon rods will continue until either the iron core has come to its deepest limited position or by increasing the arc the branch current in the thin wire of the coil has acquired such strength that whose electromagnetic force on the iron core is the predominance of the double lever lifts up and moves the latter around its axis.

After burning off the carbon rods respectively. If the arc is enlarged beyond the size where the double lever is balanced, the partial current in the thin wire of the coil also increases, pulls the iron core higher, until lever F with tooth χ disengages from the steering wheel at position ο and the carbon rods approach each other, until the branch current in the thin wire of the coil is reduced by reducing the arc and the iron core sinks, whereby lever F is loaded again and the climbing wheel is inhibited.

The same game is repeated when the arc has again reached the corresponding length until the upper carbon holder touches the stop pin α.

The arc then increases until the branch current in the thin wire of the coil lifts the iron core to its highest position and switches on the bypass. Since this latter offers very little resistance to the current, the arc is then extinguished and the current passes through this secondary loop unhindered and keeps the iron core in the highest position, as well as the contact J closed, until either the current is interrupted or after the insertion of new carbon rods Lamp comes back into action.

Claims (3)

Patent Claims: 1. Removal of the carbon rods from one another in the specified manner to produce the electric arc by mechanical means by the corresponding effect of the dead weight of one or more iron cores C on the carbon guide mechanism of an electric lamp. 2. Use of a movable lever F with tooth x, whose weight is appropriately regulated, which at a certain position falls into the teeth of a climbing gear A connected to the coal guide mechanism, from which it slows down the movement of the coal guide mechanism, as well as further at Load from the iron cores C mentioned under 1. by means of a fork E connected to them rotates the climbing wheel around itself in such a way that the carbon rods are removed from one another. 3. Use of a shunt wire of low resistance, wound on a coil, which is switched on at the highest position of the iron cores C mentioned under 1. by closing a contact J and fixes the latter in the highest position through its electromagnetic force on the iron cores C, as well as thereby keeps the contact J closed.
