Engineer Wilhelm SIDIK, Darmstadt Multiple lamp holder for strobe lights

The hiring concerns a multiple lamp socket for Blit «- leuohten and refers in particular to an institution in which the used lamp is automatically ejected and a new flash lamp is brought into a ready-to-use position

When making photographic recordings with flash, there is often the wish »as quickly as possible one after the other to be able to take several flash photos without the cumbersome removal of the used lamp and inserting it a new lamp is required.

According to the hiring, the operation of a flashlight device »which has a larger number of flash lamps in a magazine contains, particularly simplified in that the flash lamps can be inserted into a rotatable turret head and through Simply turn the turret head one after the other into an advanced position of use, e.g. at the bottom of a reflector and ejected by turning the head further after exposure.

The turret head is preferably designed as a removable magazine, which has a number of cylindrical Has cavities in each of which a lamp socket in the axial Direction against the bias of a spring is arranged displaceable * If a lamp is inserted into the socket » then the socket can be pushed back until the lamp disappears into the cavity. The socket is pressed into the Position held in place by a locking spring. By Aue-

Release of the locking spring can lower the lamp with the socket the action of the spring can be broken into the advanced position of use. The locking springs are preferably with each provided a projection which protrudes laterally from the cylindrical cavity, e.g. in the radial direction, and in the path a release lever.

A locking lever is expediently attached to each lamp socket, which locks the lamp socket in the lamp socket so that the lamp is held in the socket both in the pushed-in position and in the advanced position The locking lever has an outwardly protruding shoulder, actuation of which triggers the locking lever and the lamp is ejected.

Per turret is useful by means of a central cylindrical Cavity mounted on a fixed axis of rotation connected to the housing. The release lever can be attached to this be attached, which comes into engagement with the lugs of the locking springs when the head is rotated. The axis is useful firmly connected to the carrier for the reflector.

Xn the path of the outwardly protruding lugs of the locking lever a trigger piece is arranged to actuate the ejector in such a way that it is already in the first part of the rotation of the turret head comes into engagement with the lugs of the locking lever and ejects the lamp, so that the turret continues to rotate without being obstructed by the lamp

In order to check that each lamp is ready for operation and that it is making perfect contact before it is ignited, it is advisable to have a to arrange known test glow lamp on the axis *

In order to further simplify the operation, it can be useful between the elevator of the camera and the rotating device to provide a flexible connection for the turret head,

so that automatically when the express elevator is operated, too the revolver head is rotated and a new flash lamp is brought to the ready position. To this end, the edge of the turret toothed and via a worm gear drive be connected to the flexible drive shaft.

An example of the innovation is shown in the drawings shown, namely shows

Fig. 1 is an overall view of the strobe light with reflector

and turret j
Fig. 2 shows a section through the turret head and the related parts}

Fig. 3 shows a plan view of the turret and Flg. A is a view of the establishment from the opposite

Page like Fig. 3. -,

The flashlight of Fig. 1 has a housing 1 made of e.g. Metal or molded material can exist. A reflector 2 made of aluminum, for example, can be inserted into the housing and has a grained, highly reflective inner surface. A turret 3t is also located in the housing whose cylindrical end face 4 protrudes to the rear of the housing and is provided with a rimmed edge, so that the turret head can be rotated from the outside. A battery 5 and a capacitor 6 for ignition can also be found in the housing the flash lamp can be provided in order to actuate the flash lamp in a manner known per se. The housing can also have a Have mounting bracket 7 so that it can be connected to the camera in a suitable manner.

In the example described here, the turret head contains six cylindrical cavities β, in each of which a lamp holder 9 is arranged displaceably in the axial direction is. The lamp socket 9 is also cylindrical on the outside, so that it is displaced like a piston in the cavity can be. A spring 10 is in each of the cavities

• m A, «·

arranged and searches the fit 9 for rom, i.e. in the Aneicht of Fig. 2 to slide to the right. You fit 9 points a hole for receiving the base 11 of a flash lamp 12 in the middle. When the flash lamp is inserted, it lays in Locking lever 15t which has e.g. an angular shape against which lower band 14 of the Lampejiisooktl and at the same time represents the an electrical connection line. The other pole of the lamp cap rests against a spring 15 which is compressed so far that they will be able to throw out the lamp, when the locking lever 1 $ is swiveled to the right with an arm pointing upwards, the lamp is released.

The fit 9 can be moved with the lamp inserted in Fig. 2 near the left until it is through a locking spring 16 and a Projection 16 * is held in the depressed position. In this position the lamp 12 disappears completely inside of the cylindrical cavity

The turret 3 has, in addition to the sixo openings for the The lamps are also received by a cylindrical bore 17 into which an axis 18 protrudes, on which the revolver head rotates can be. This axis forms part of the housing or is rigidly connected to it. It has two trigger organs, namely a trigger 19 which acts on the locking springs 16 when they are rotated past him and a trigger 20, which acts on the locking lever 13 when they slide along the trigger 20 when the turret head is rotated Both triggers 19 and 20 have sloping surfaces so that when the head is rotated, the extensions of the springs 16 or the lever 13 are moved in the desired manner; in fact the extension of the spring 16 is pivoted downwards in FIG.

while the locking lever 13 is pivoted with its upper leg to the right. The release levers 19 and 20 are so arranged with respect to their angular position that, starting from a boom position in which a lamp is in the advanced position, the lever 13 first comes into contact with the projection 20

comes so that the lamp is thrown out. The turret can can now be rotated further without a lamp hindering this rotation, until at the end of the movement the spring 16 of the next Magazine opening comes into engagement with the release lever 19, so that under the action of the spring 10, the fit 9 snaps towards rom and the lamp is moved into the reflector opening will.

The electrical circuit expediently runs via a glow lamp 21, the socket 22 of which is attached to the axle 18 »The circuit leads from a spring 23 over the glow lamp 21 to a spring 24 »which connects to a metallic end plate 25 on the front end wall of the turret head manufactures. When the lamp socket 9 is pushed forward, an electrically conductive connection is established between this metal coating 25 and a stop 26 is made in the socket, which is connected to the spring 15. From here the circuit leads over the Flash lamp to the outer part of the base 11 and over the Locking lever 13 to the second terminal of the battery 5 'or to the release switch, which is mounted in the camera.

When using the device, the reflector 2 is first put on, which with the help of two springs 27 and 28 in a bayonet socket is supported. The turret can be removed from the rear and comes with six flash lamps loaded by inserting them into the sockets and pushing them inwards with them. Here are the Springs 15 and 10 stretched. The turret goes into the device inserted and rotated until one of the springs 16 comes into engagement with the release lever 19, so that the relevant lamps Version 9 is moved forward. The lamp 12 is located now in standby position and can be ignited.

After the recording, the turret head is rotated further. As a result, the locking lever 13 only comes into engagement with the trigger 20, and the lamp is ejected by the spring 9. With a further rotation, the spring 16 becomes the next magazine opening

triggered. The lamp with the socket snaps forward, and that Device is ready for operation again

As already mentioned, »the rotation of the turret head can go through Actuation of the rapid lift of the camera take place. For this purpose there is a drive connection between the high-speed elevator and the turret head, which for example consist of a flexible Shaft, a cord drive or the like can exist. The edge of the turret can be serrated and over a Worm gear drive to be connected to the high-speed elevator.

Eb is also possible to choose the number of lamps accommodated by the turret head differently and the turret head in from a constructive point of view, in particular with regard to the release lever, etc. without leaving the area of the control system *
