Description

Предлагаемое устройство, скека которого изображена на чертеже,- способ, которым можно включать телефонные аппараты в телеграф-, ную линию п состоит из трансформаторов , соединенных между собою либо линейными проводами, либо двухпроводными телефонными лини ми. Вторичные обмотки этих трансформаторов разделены на две симметричных секции, соединены друг с другом через два последовательно соединенных конденсатора 4, 4 и 42, 4з с одной заземленной обкладкой у каждого, предназначенные дл  сглаживани  импульсов тока, посылаемых телеграфными аппаратами. Последние присоедин ютс  к незаземленным обмоткам конденсаторов 4, 4, 40, 4з, в то врем  как телефонные аппараты включаютс  через конденсаторы в первичные обмотки трансформаторов .The proposed device, the bounce of which is shown in the drawing, is a method by which telephone sets can be included in the telegraph, n line consists of transformers connected between themselves either by linear wires or two-wire telephone lines. The secondary windings of these transformers are divided into two symmetrical sections, connected to each other through two series-connected capacitors 4, 4 and 42, 4h with one grounded facing each, designed to smooth current pulses sent by telegraph devices. The latter are connected to ungrounded windings of capacitors 4, 4, 40, 4h, while telephone sets are connected through capacitors to the primary windings of transformers.

Изображенные на чертеже телефоны 5,5 включены на промежуточныхThe phones 5.5 shown in the drawing are included on intermediate

станци х, не имеющих телеграфных аппаратов.stations that do not have telegraph devices.

Предмет патента.The subject of the patent.

1.Устройство дл  включени  телефонных аппаратов в телеграфную линию с помощью трансформаторов, характеризующеес  тем, что вторичные обмотки трансформаторов разделены на две симметричных секции, соединенные последовательно друг с другом через два последовате.ьно соединенных конденсатора 4,4, к обкладкам которых, соединенным с обмотками трансформаторов, присоединены заземленные телеграфные аппараты, какоеые конденсаторы заземлены обращенными друг к другу обкладками и назначены дл  сглаживани  импульсов тока, посылаемых телеграфными аппаратами1. A device for switching telephones into a telegraph line using transformers, characterized in that the secondary windings of transformers are divided into two symmetric sections connected in series with each other through two successively connected capacitors 4.4, to the plates of which are connected to the windings transformers, connected grounded telegraph devices, which capacitors are grounded by facing plates and assigned to smooth current pulses sent by telegraphs E devices

2.Видоизменение охарактеризованного в п. 1 устройства, отличающеес  тем, что один или оба линейных провода заменены двухпроводными телефонными лини ми.2. Variation of the device described in paragraph 1, characterized in that one or both of the line wires are replaced by two-wire telephone lines.
