SIGNAL SYSTEM.
Specification of Letters Patent.
Application filed January 3!), 190B. Serial No. 413,342.
- To all whom (it may concern:
Be it known that I, JOHN HALL, a citizen of the United States, residing at Schenthe object ofmy invention is to provide a novel system of this character in which the number of control conductors or leads is reduced to a minimum.
. My invention consists in providing a number of separate sources of current for the receivers, a group of leads, each of which is common to one source and to all the magnet windings of one indicator, 9. second group of leads common to all the receivers, the several magnets of each receiver being connected to different leads of thecup, and switchesarranged to connect 'eac source to any one of the leads of the latter group.
. My invention will best be understood by reference, to the accompanying drawing, which shows diagrammatically a signal system arranged in accordance with my invention.
In thedrawing two receivers A} and-Ar are shown. These are indicated diagrammaticallyas synchronous indicators of a typewell knownin theart, employing a lurality of stationary magnets a',a polar- 1zed armature b, and an indicator, shown at c as a numbered plate or dial driven by the armature and adapted to display any one of the numbers on the plate or dial. B and B representseparatesourcesof current for the receivers. These are indicated as a pair of small generators on the same shaft. All the magnet windings a of receiver A have a common terminal connected through a lead 1, to oneterminal of the generator B The magnet windings a of receiver A are connected through a common terminal and the lead 2 to one-terminal of the small generator B Extensions 1' and 2' of the leads 1 and 2 run to the transmitting station at which are a pair of controlling switches C and G The switch C is-arranged to connect the lead 1, and consequently the generator B Patented Dec.,1, 190s.
to any one of the group of five leads 3, 4, 5, 6 and 7. The switch C is similarly ar-' ranged to connect lead 2 and generator B to any one of. this group of leads. At the receivers, the ma nets a of each receiver are connected to di erent leads of this group.
The polarizing coils of the armatures. of the receivers are energized from any suitable source. They are'indicated as being connected in shunt to the generator B 'With the switches C and C in the positions shown, both generators B and B are connected to the lead 3', so that the winding a of both receivers whichis connected to the lead 3 is energized, so that the receivers give similar i ndications.- If the switch C" is .moved to connect lead 1 to lead 4, the magnet winding of receiver A, connected tolead 4, will be energized, so as to change the indication of this receiver; while if switch C is not moved, the indication of receiver A, is
not changed. The operation of each receiver is thus independent of the other, al-
though one group ofleads is common to both of them.
By the use of this system, the ten magnet windings a of the two receivers are selectively controllable by means of seven trans mission leads. If three receivers and three sources of current were employed, the fifteen magnet windin s a ofthe" three receivers would be .contro led by eight leads; and four receivers with their twenty magnet wind ings would be controlled by nine leads, etc. Except for energizing the polarizing coils of the receiver armatures, it makes no difference whether the current sources are at the receiving or transmitting station.
I do not desire to limit myself to the particular construction and arrangement of parts here shown, but aim 'inthe appended claims to cover all modifications which are within the scope of my invention.-
What I claim as new and desire to secure by Letters Patent of the United States, is,-'
1. In a signaling system, a plurality of receiving devlces each having a plurality of magnet. windings, a plurality of current. sources, an 1ndependent lead foreachfsourceand one of said receiving devices connected at the device to a common terminal for the magnets of the device, a group of leads com mon to the receiving, devices, the several magnets of each device being connected to:
gliiferent leads of the group, and a switch 5 the source to any lead of said group.
for each source arranged to connect the source to any lead of said group; v
2. In a slgnaling system, a plurality of remagnet windings and the windings of each device having one common terminal, a plurality of current sources, independent leads from the common terminals of the several leads common to the several devices, the several magnets of each device being connected to different leads of the group, and'a switch for each source arranged to connect 3. In a signaling system, a plurality of reg ceiving devices having a plurality of magnet windings, a plurality of current sources, leads common to the magnets of each device but independent as to the several devices, leads common to the several devicesbut independent as to the magnets of each device, connections from each source to one of the former set ofleads, and a switch for each source arranged to connect the source to any one of the latter set of leads.
In witness whereof, I have hereunto set my hand this 28th day of January, 1908.
JOHN L. HALL.
