JOHN NEWBERRY REYNOLDS, OF GREENWIQH, CONNECTICUTQASSIGNOB TO WESTERN ELECTRIC COMPANY, INCORPORATED, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.
SWITCH MECHANISM.
To allwhom it may concern:
Be it known that I, JOHN NEWBERRY REY- NoLvs,ia citizen of the United States, reside ing at Greenwich in the county of Fairfield and State of Connecticut, have invented cer tain new and useful Improvements in Switch Mechanisms, of which the following is a full, clear, concise, and exact descrip- '-tion.
This invention relates to telephone switch mechanism, and more particularly to improvements in switch mechanisms such as shown 'in Patent No. 1,131,734 of March 16,
I 1915, in which circuit connections are established through the agency of two sets of relatively movable contact I members carried by movable bars hereinafter termed trunk and line bars. The trunk bars are adapted to be selectively displaced to bring their contacts into position to be engaged by contacts upon a line bar, the'engagement between contacts of an operated line bar and trunk bar causing said trunk bar to be swung to a position where the contacts will leasing magnets for restoring the trunk bar lease the latched trunk bar.
when taken for use.
The object of this invention is to simplify the structure and improve the operation of such switches.
' In accordance with the general features of this invention, there is 'provided a common latching and releasing bar for the trunk members with a single magnet which in the operation of the switch is operated to re- Individual magnets are provided for setting the trunk bars into latched position.
The drawing is a perspective view,- with parts broken away, of a' switch embodying the features of this invention.
As shown in the drawing, there is a frame comprising endmembers 2 and 3, and top and bottom members 4 and 5.- Pivotally supportedcin the top andbottom members 4 i and 5 are trun-k bar'si ;-6-,; each carrying a plurality of sets of "contact members 7-7. At-their lower ends, each of the trunk bars is providedwith a projecting latching mem- Specification of Letters Patent. Patented Feb 13 1917 Application filed May 22, 1916. Serial No. 99,115.
her 8, adapted to be engaged by anarmature 9 of an electromagnet 10, individual to each of'said trunk bars. Extending longitudinally of the frame is a swinging latch plat-e 12, having projections =13-13 thereon, adapted to engage the latch member 8 of a displaced trunk bar to retain it temporarily in such displaced position. Pivotally supported in the end frame members 2 and 3 are line bars 15-15, each provided with a plurality of sets of contacts 16-46, the said line bars 1'515 being adapted to be moved longitudinally by,n1eans of elec romagnets 1717, and to be rotated through a slight angle to bring the contacts 16 thereon into engagement with the contacts 7 of a dis placed trunk bar. The line bars are swung through an angle by means of a cam pro: jection 20, secured to the end frame member 3. and which is engaged by a projecting member 21', secured to the end of the line bar 15 adjacent the frame member 3.
Located at one end of the frame is anelectromagnet 25, adapted when energized to attract a projection 26 on the latch plate 12 to swing said latch plate to a position where the latch member 8 of a displaced trunk bar will be released from its held position.
Each trunk barv is adapted to be displaced against the tension of a spring 28 which operates when the trunk bar is released from its latched position to return it to a normal position, where the sets of contacts 77 thereon are out of position to be engaged by the sets of contacts 16-16, carried by the line bars.
The operation of the electromagnet 25 swings the latch plate 12 against the tension of a spring 30, which, when the magnet 25 is deenergized, returns the latch plate tq position, where the projections 13-13 thereon will be in a position to engage and hold a displaced latched member 8 on one of the trunk bars 6.
What is claimed is:
1. In a connecting switch, a plurality of trunk bars, contacts on said trunk bars, a
plurality of line bars, contacts on said line bars adapted to engage'the contacts on said trunk bars, individual means for displacing each of said trunk bars into position to have its contacts engaged by the contacts of said line bars, and a latching plate common to all of said trunk bars for retaining a trunk bar in displaced position :2. In a'connecting switch, a plurality of trunk bars, contacts on said bars, a plurality of line bars, contacts on said line bars adapted to engage With-the contacts on said trunk bars, an individual electromagnet for each trunk bar adapted to move it into position to have its contacts engaged by the contacts-of said line bars, a movable'latching bar common' to all of said trunk bars for latching said trunk bars in displaced position, and an electromagnet for operating said latch bar to release a displacedone of said trunk ba'rs when the contacts thereon are in engagement with the contacts on a'line bar. Y
3. In a connecting switch, a plurality of trunk bars, contacts carried by said. trunk bars, a plurality of line bars, contacts on the latch member of a displaced trunk bar,
and a releasing magnet'for swinging said latch plate .to release the latch member of a displaced trunk bar.
In witness whereof, I hereunto subscribe my name this 18th day of May A. D., 1916.-
JOHN NEWBERRYREYNOLDS.
