GERHARD \VILHELM VAN VIANEN, OF COLOGNE, GERMANY.

ELECTRIC TIME-SIGNAL.

SPECIFICATION forming part of Letters Patent No. 499,062, dated June 6, 1893.

Application filed August 2,1892- Sen'al llo. 441,981. (No model.)

To aZZ whom it may concern.-

Be it known that LGEEHAEDWILHELM VAN VIANEN, of Cologne, in the Kingdom of Prussia and German Empire, haveinvented anew and useful Improvement in Electric Signals or Alarms, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates toimprovements in or connected with electric alarms, applicable for dwelling and other places such as hotels, and when applied in such places for example, permits the visitors, guests, or otherwise, to set the alarms for any time in their own rooms; and the ringing of the bell in any particular room then takes place exactly at the predetermined time and automatically, so that the guest or other person or persons is or are not dependent on the punctuality of servants or the like.

According to my invention the whole apparatus is set in motion by a clock which is provided with a specially constructed contact mechanism as hereinafter described for the purpose, and in each room is placed a plug contact apparatus provided with a bell which serves as an alarm. Conducting wires connect the clock apparatus and alarm apparatus.

My invention will be readily understood by reference to the accompanying drawings.

Figure 1 shows in plan or elevation and Fig. 2 in section the clock contact arrangement or so much of the same as will be necessary to describe this invention; and Figs. 3 and 4 are similar views of the plug contact and alarm mechanism. Fig. 5 shows in elevation and section one of the plugs detached. Fig. 6 is a diagram View illustrating an installment of the apparatus constructed and arranged according to my invention, wherein conducting wires are shown carried from the apparatus, shown in Figs. 3 and at, to the clock shown in Figs. land 2. The number of these wires is regulated by the intervals at which the alarm is required to be set; for instance as shown in the diagram view Fig. 6, an interval of half an hour is chosen in consequence of which there are twice twelve (twenty-four) conductors from the clock, together with a return conductor R, thus making a total of twenty-five wires. The return conductor goes direct to the plug apparatus, Figs. 3 and 4, of the separate rooms, and is there connected with the sounder and ends in a metal (brass) ring 1*. To this ring twenty-four plates a are concentrically attached, see Figs 3 and 4. These plates are insulated from the ring r and have a semicircular opening which corresponds to a like opening in the ring 0, so that thereby a circular space is formed, into which a plug 5 (Fig. 5) can be inserted, thus setting up an electrical contact between the ring 7' and the plate in question. To these twenty-four plates the ends of the whole of the twenty-four conductors are attached, so that any conductor may be connected with the return conductor R as desired.

The clock (Figs. 1 and 2) requires strong works and accurate movement; but the motionwork may be of any desired construction. The contact is eitected by means of two springs ff, screwed onto two clamps 7c 70, which can be adjusted by the screws (1 d. The springs ff slide upon a contact plate 13 which carries a contact arm I), provided with a spring 2', upon which a platinum contact 0 is fixed. A circle of metal plates a extends around the contacts; the plates a form the ends of the twenty-four conductors and are screwed onto an insulated plate which carries a circular continuation g. Screws hare screwed through the shoulders of the plates a and pass through borings in the ring continuation g and in front they carry platinum contacts.

The plate 1) is rigidly connected with the small indicator of the clock, so that it, and with it the contact arm 1), makes a revolution in twelve hours. The contact arm 1) thereby makes contact, hourly, half-hourly, quarterhourly, be, according to the number of the plates a. Thus, according to the place where the guest may have inserted the plug in the apparatus, the bell in his room will be sounded at a fixed time and an alarm will be made.

WVhat I claim, and desire to secure by Letters Patent of the United States, is

In an electric signal and alarm apparatus the combination with a ring g, screws h and the dial plate, of the conducting disk or plate 1) under the dial and provided with an arm Z) having a contact spring 2' to engage the screw GERIIARD WILIIELM VAN VIANEN. 5 points and the springs ff engaging the periphery of the disk 29 with their inner ends Witnesses:

In witness whereof I have hereunto set my hand in presence of two witnesses.
