bined microtelephone, ancla separate casing containing the accessories, an electric cable connecting both said parts. It is further known to suspend such microtelephoneson an electric or other cable, which for this pur,

pose is guided by an overhead roller.

The invention consists therein that a microtelephone is suspended on' a cable influenced by a counterweight in such manner as to give the microtelephone automatically an upward tension, and the microtelephone is provided with a device adapted to be fastened below the chin or on the clothes of the user so as to be automatically held'in the use position.

arrangement with a modi- According to Fig. l a casing 1 of atable' telephone is mounted by side near a wall on a bracket. A switchrod 2 is held down by two screw springs 3, fastened to the bracket, onto the telephone fork 1 provided for receiving the microtelephone. The telephone cable 4, coming from the casing l,.is fastened to said switch rod 2 and guided over over- 7 hand rollers 5, 6-to the microtelephone consisting of a telephone 7, a handle 8 and a microphone 9. The springs 3 are as strong as to overcome the weight of said microtelephone 7-9, so that they endure a resting position in which the telephone fork 1 is pressed down and the speaking current is interrupted in usual way. For allowing the microtelephone to be drawn farther away than allowed by the springs 3, a rolling weight 10 is applied to the cable 4 so as to V According produce in the latter a yielding loopfl As forraising the weight 10 the tension in the cablemay be augmented by pullingdown the microtelephone, this augmented tension over comes the springs 3 and causes the fork-'1 to raise and the speaking circuit to beclosed.

According to Fig. 2 in a device corresponding 'to that shownin Fig. 1 and designed by the same reference numerals, instead of a 'table telephone a' special switch 11 is-con-v nected-to'the cable 4 for eflecting the closing and interrupting of the callingand speaking circuits in the same way as" the telephone forkil (Fig.-1)for a' telephone hook. This switch casing ll allows atable telephone orwall telephone to be connected to it. without necessitatingany alterations on the telephone casing. I I j g V i to Fig.3 111 a similar arrangement near the'first roller 5 an add1t1onal 1 roller 12 is applied to thecabled, so that from the rolling weight'lO both cable parts run'straight upward, and the rolling weight 10 ispositioned straight over the telephone fork 1",so as to rest on "thelatter and press it down as long as no pull is exerted on the microtelephone 79. Hereby no springs are needed, and the cable 4; has an essentially equal tension in all positions, which for the use is a special advantage. lhe operation corresponds to that of the first embodiments.

According ,to Fig. 4 for all embodiments the microtelephone 79 is provided with a wire bow 13 adaptedto be put under the chin of the user and having a part 13' fitting round the users throat in such manner, that under the upward pull of the cable 4: the microphone 9 is held near to the mouth and the telephone 7 against the ear of the user. 7

A push button 14 is provided onthe handle 8 of the microtelephone for short circuiting the, microphone or interrupting the speaking current or the like purposes. A line selector 5 in the form of a sledge or rolling band is inserted forthe case, that line selection shall be provided and the selector shall not remain in the usual table or wall casing. The cable 4 contains the several conductors needed for such purposes.

We claim:

1. A telephone arrangement comprising in combination a microtelephone, a cable connected to said microtelephone, means for guiding said cable upward, means for exerting an upward tension in said cable overcoming the weight of said microtelephone, and mans on said microtelephone adapted to be fixed on the user for holding it on the head of the user against said tension.

2.v A telephone arrangement comprising in combination a microtelephone a cable connected to said microtelephone, means for guiding said cable upward, means for ex-,

erting an upward tension in said cable overcomin the weight of said microtelephone, and a ow on said microtelephone, fitting to the lower side of the chin of a user.

i 3. A telephone arrangement comprising in go combination a microtelephone, a cable connected to said microtelephone, means for guiding said cable upward, means for exerting an upward tension in said cable overcoming the weight of said microtelephone, a bow on said microtelephone, fitting to the lower side of the chin of a user, and a part on said bow, fitting round the throat of a user.

4. A telephone arrangement comprising in a combination a microtelephone, a cable coni nected to a said microtelephone, means for guiding said cable upward, means for exciting an upward tension in said cable overcoming the weight of said microtelephone, 5 means on said microtelephone adapted to be fixed on the user, for holding it on the head of the user against said tension, and a switch operatively connected to said cable so as to close the speaking circuit at a pull exerted on the cableand interrupt said cir- 7 cuit at relieving said pull. i 7

In witness whereof we affix our signatures. ALEXANDER ARCHANGELSKY. I RUDOLF GOLDBERG.
