CLAUDE F. REDMON, CLAUDE G. REDMON. LILLARD K. REDMON, AND JOHN T. REDMON,
OF PARIS. KENTUCKY.
AUTOMATIC CIRCUIT MECHANISM.
Application filed September 18, 1919.
To all whom it may concern:
Be it known that we, CLAUDE F. REnMoN, CLAUDE G. REDMON, LILLARD K. RnnMoN, and J OHN T. REnMoN, citizens of the United States, residing at Paris, in the county of Bourbon and State of Kentucky, have invented certain new and useful Improvements in Automatic Circuit Mechanism; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skllled in the art to which it appertains to make and use the same.
This invention relates to reels and particularly to reels for wires carrying electrical currents and especially to an automatic circuit mechanism for said reels.
An object of this invention is to provide a means for automatically breaking an electrical circuit through a wire wound upon a reel upon the return of the said wire to a predetermined position relative to said reel.
A further object of this invention is to provide a means for breaking a circuit in an electric wire wound upon a reel, by a stop ailixed upon said wire actuating the circuit breaker.
A further object of this invention is to provide an improved means for forming a circuit through rotary parts of a reel for electric wires.
WVith these and other objects in view, the invention consists of the construction, combination, and the detail and arrangement of parts as hereinafter more fully described and claimed.
In the drawings:
Figure 1 is a side elevation of a reel partly broken away to better illustrate this attachment.
Fig. 2 is a fragmentary section of the contact points.
Fig. 3 is a perspective of the actuating mechanism for pushing the contact points.
Fig. 4 is a detail of the rotary contact points.
Referring to the drawings, a reel 2 mounted on a shaft 1 and supported by a yoke frame 13 is provided with any suitable spring mechanism 20 to rewind said spool automatically and the electrical double conductor cord 3, which combination of elements are well known and found in many forms in common use.
To the frame 13 of this well known device Specification of Letters Patent.
Patented Nov. 2, 1920.
Serial No. 324,640.
is attached in a suitable housing 19, two mutually insulated and spaced spring circuit members 9, 9, member 9' being slightly longer than 9 and its exposed end tipped with insulation 8. A yoke frame having arms 12, 12 is also secured to the frame 13,
. frame 13 is a non-rotating circuit collar 15 electrically connected to one of the circuit members 9, or 9 and a second circuit collar 14 is rotatively mounted adjacent to collar 15 and electrically connected to one of the conductors of cord 3. These collars are held in contact by means of a spring 16 as shown in Fig. 2.
In operation when wire 3 is paid out in the usual manner on a reel of this type and especially in shops not having a switch at the light it is desirable that the light be extinguished upon the return of the Wire to its normal position in the reel. By the operation of this device when the adjustable stop 1 comes in contact with bell crank 5 it operates by the pulling of the spring, which draws in the paid out line, to turn the bell crank 5, thereby pushing open the circuit breaker 9 and breaking the circuit.
No claim of novelty is made relative to reels for paying out electrical wires, the vital features of this invention residing in automatically breaking the circuit and extinguishing the light upon the return of the wires to a predetermined position and he specific means for accomplishing these purposes.
What we claim is:
1. In an automatic switch for conductor reels, the combination of spaced spring contact members, a yoke embracing the reel carrying a lever, a contact actuating arm pivoted to said lever and means attached to the conductor for operating said lever.
2. In an automatic switch for conductor reels, the combination of spaced spring contact members, a yoke embracing the reel and carrying a conductor guide and a lever, a contact operating arm pivoted to said lever and means secured to the conduit for operating said lever.
3. In an automatic switch for conductor reels, the combination of spaced spring contact members normally closed, a yoke embracing the reel and carrying a conduit guide, a lever pivoted on said yoke having an arm disposed in the path of the conductor, a contact operating arm pivoted to said lever and engaging one of said contact members, and means adjustably secured to the conductor to operate said lever and separate said contact members.
In testimony whereof we afiix our signatures.
