PATENT OFFICE.

The invention relates to a device for conveying letters, newspapers and others small objects by means of an elevator box to the individual floors of a Building in which the mailbox set up on the ground floor is in a row of compartments is divided.

The invention consists essentially in the fact that the axis of rotation of the floor each ίο The mailbox compartment has a lever that is inserted into the closed position of the bottom is held by the armature of an electromagnet, which is switched on in a circuit led to the floor in question. When this circuit is closed from the floor in question, the anchor dressed. This deprives the lever of its support and thus the ground of the corresponding mailbox compartment folded down so that the letters in fall into the elevator box, which can be raised and lowered by any means.

On the drawing show:

Fig. Ι a vertical section through the mailbox and the elevator shaft connected to it; At the same time, the electrical network to the individual floors is illustrated here,

Fig. 2 the mailbox in front view,
Fig. 3 is a horizontal section along the line AB of Fig. 1,

Fig. 4 shows a section along the line CD of Fig. 3 and

Fig. 5 is a vertical section through mailboxes on two opposite Sides of the elevator shaft are attached.

A mailbox is available for receiving the incoming mail, which has as many compartments as there are apartments. The openings for the letters are closed by movable, inward or outward flaps α , which bear the appropriate label. With these flaps α levers b are rigidly connected, which brush over contacts c on the mailbox, so that an electrical line is closed or interrupted by opening a flap a. The letters now fall onto the lower movable closure flap d in the individual compartments of the mailbox. The axes of rotation of the flaps d are rigidly connected to levers e (Fig. 3 and 4) which rest on the armature of electromagnets f on the mailbox. These electromagnets are connected to the electrical line g . In this, the contacts h and the panel box i or also noise signals k are located on the individual floors.

The slide rod Z, which runs in guides m , also sits on the mailbox. The upper end of the rod Z is a movable hook n in which an inclined slot 0 is located. In this engages a fixed on the outer wall of the mailbox pin ρ so that when moving up the

Claims (2)

Slide rod Z the upper movable hook η through the inclined slot guide ο to the rear, when the slide rod Z goes down, it moves forward again. Pins q are now attached to this, against which the levers e of the fallen flaps d rest. When the slide rod Z is moved upwards, the levers e are taken along by the pins q and placed again ίο on the armatures of the electromagnets f. The movement of the slide rod Z takes place in that a latch 5 engages under the movable hook η of the rod Z when the elevator container r is pulled open. When the elevator container moves downwards, the latch 5 folds up when the hook η is touched; but after passing the hook η it immediately falls back into the horizontal position. The levers b on the flaps a are brought back into the correct position by springs t (Fig. 4), u represent elements for the electrical lines g. The numbers I, II, III represent the different floors. If a letter arrives for floor I, the person delivering it must throw it into the relevant compartment of the mailbox through the opening for the first floor. In order to be able to do this, the mail carrier moves the flap a backwards. As a result of the movement of the lever b that takes place here, the associated contact c and thus an electrical line are closed. In the floor I, the bell sounds k and indicates the insertion of the letter. As soon as the flap α is released again, the spring t pulls the lever b downwards, thus also the flap α again in front of the opening. Contact c of floor I opens again and the electrical line is interrupted. Instead of a bell k, a panel box i, as indicated in floors II or III, or both can be switched on here. In the case of a tableau box i, a sign with the corresponding inscription »Posta or the like is then visible, whereby the receipt of the letter can also be indicated. Now the recipient of the letter in question brings the elevator container r down. During its downward movement, the latch s hits the hook η on the slide Z, folds upwards (left side of FIG. 5) and, after passing the hook η, hits the horizontal position again. As soon as the elevator container r is under the mailbox, you press the contact h on floor I. This closes the associated electrical line again, the electromagnet f for the compartment belonging to floor I attracts its armature, which gives the lever resting on it e free, whereby the shutter d of the mailbox for the floor I falls down again. The letters placed in this mailbox now fall into the elevator container r below. This is now moved upwards again. The latch s on the elevator container r grips under the movable hook n when the slide Z passes, and takes it upwards with the slide rod I. The pin q of the rod Z also entrains the lever e of the flap d lying thereon until the lever e rests on the armature of the electromagnet / so that the mailbox is closed again. In the meantime, the hook η has also been pulled away from the latch s on the elevator container r by the inclined slot guide 0 and the pin ρ, so that the slide rod Z is free again (FIG. 5 right) and falls down. The elevator container r is now transported on to floor I; From here, the letters in the container can be easily removed. The same process would be repeated for the remaining floors. Godfather ν τ-Α ν saying ε: 1. A device for conveying mail and other small objects by means of an elevator box to the individual floors of a building, in which the mailbox set up on the ground floor is divided into a number of compartments, characterized in that the axis of rotation of the floor (d) of each mailbox compartment has a lever (e) carries, which is in the closed position of the bottom (d) of the armature (f) of an electromagnet. is held, which is switched on in a circuit (g) led to the floor in question, so that when the circuit is closed from the floor in question, the armature (f) is attracted, thereby depriving the lever (e) of its support and thus the bottom of the 'Corresponding mailbox compartment is brought down so that the letters or the like fall into the elevator box (r) which can be raised and lowered by any means. 2. Apparatus according to claim 1, characterized in that below the free ends of the lever (e) stops (q) are arranged, which sit on a liftable and lowerable rod (I) , so that by lifting the folded down lever (e ) lifted up to their anchor (f) and thus the letterbox bottoms (d) are brought into the locked position. 3. Device according to claim 1 and 2, characterized in that a hook (n) is knocked onto the upper end of the rod (I) which has an inclined slot (0) into which a fixed pin (p) engages so that When lifting the elevator box fr) a stop fs) attached to it and only swinging upwards takes the hook (n) and thus the rod (I) with it until the pin (ρ) ίο the hook (η) from the stop fs) is pulled away, at the same time the levers fe) are raised so far that they are held by the anchors ff) . 1 sheet of drawings.
