SELECTIVE ELECTRIC SIGNALING APPARATUS.
Specification of Letters Patent.
Patent-ed Dec. 23, 1909.
Application'filed September 25, 1908. Serial No. 454,761.
Be it known that I, JCT-IX B. Coii. of 1305- ton, in thclcounty of Suffolk and State of Massachusetts, have invented certain new and useful Improvements inSclectn'e Electric Signaling Apparatus, of whichthe t'ollowing 1s a specificat on.
This invention has for its ob e'ct to proride a selective signaling apparatus which maybe portable and includes" a base" or support and means mo'untedlthereon for closing any desired numberof electric circuits to actuate call bells or other electrically oper: atcd devices included in said circuits, a single movable signal-closing device or push piece being adapted to close either of the circuits so that in e. si naling system which includes a plurality 0% independent instruments, a single push iece or circuit closer may be used selective through either of the instruments.
The invention consists in the improve ments which I will now proceed to describe and claim.
Of the accompanying drawings, forming a part of this specification,- igure 1 represents a plan View of a signaling apparatus embodying my invention. Fig.2 representsa section on line 22 of Fig. 1. Fig. 3 represents a section on line 3-3 of Fig. 1.
The same reference characters indicate the sameparts in all of the figures.
In the drawings, 12 represents a base-or support which may be orta-ble and adapted to be secured on a esk or table, either loosely or detachably connected thereto by screws or otherwise.
13 represents a carrier which is so connected with the base 12 as to move in a predetermined path relatively to the same, the carrier bein preferably adapted to oscillate upon a fixe stud 14 secured to the base.
15 represents a circuit terminal attached to the carrier and movable therewith in a predetermined path, the terminal being yieldingly held ina retracted position out of contact with the fixed circuit terminals, As here shown, the
any suitable metal which is a good conductor of electricity, one end of the terminal being 'afiixed to the carrier 13, and the other free to move toward and from the base 12, and normally retracted from the base by its own resilience. Y
to close the circuit 16.- 16 represent a series of fixed-+ circuit terminals attached to the base 12, the fseries coinciding with the path in which the movable terminal 15 is adapted to travel, the arrangement being such that the movable terminal may be brought into coincidence with either ofthe fixed terminals by amovement of the carrier 13, and then projected from its normal retracted positionintocontact with the fixed terminal withivhich'it coincides. 'Thc movable'terminal may be projected by means of a push piece 17 slidingly mounted on the carrier 13, the said push piece preferably having at its outer end a head or button of insulating material, and
bearing atits inner end on the movable terminal 15'. I 18 represents a battery or other source of electricity, one pole of which is connected Each of the, fixed terminals 16 is connected by an individual circuit wire 20 with the opposite pole of the battery, each circuit wire 20 including an electric signaling instrument 21 of any suitable character, the said battery circuit wires and terminals constituting a plurality of normally open circuits corresponding in number to the fixed terminals, and each adapted to be closed by contactof the movable terminal 15 with a fixedterminal 16. The several circuit wires may be grouped in a cable at ornear the point where they leave the base 12. i
'The carrier 13 is rovided with a pointer 22, and the base 12 is provided with a plurality of indicators 23 corresponding in" number and position to the fixed terminals 16, the arrangement being such that when the movable terminal 15 coincides with the fixed terminal 16 of a given circuit, the pointer 22 will coincide with the indicator, 23 which pertains to that circuit. The indicators 23 may becards suitably inscribed and relnovably inserted in pockets 24 which are formed bythe upper surface of the base 12, the under surface of a plate 25 affixed to the upper side of the base, and ribs 26 formed on'the under} side of the plate and forming partitions between the pockets. The outer ends of the pockets are, open so thatditferent indicator cards may beused' interchangeably.
It will be seen that the base 12 may be.
