Y Renewed September 23, 1937 I 7 Claims.
The present invention relates to electric switches 01' the type having liquid contact circuit closers for controlling the flow of current.
The object of my invention is to provide an improved construction and arrangement in a taken on line 3-3 of Fig. 1; Fig. 4 is a diagram matic view showing the construction and operation of the liquid contact circuit closer; Fig. 5 is a fragmentary sectional elevation taken on line 5-5 of Fig. 2, and Fig. 6 is a top plan view or the switch with the liquid contact'circuit closer removed,
' Referring to the drawing, I have illustrated my invention using a liquid contact circuit closer 20 having a pair of cup-shaped metal terminals I which are separated by an insulating diaphragm 2 01' refractory material, such as a ceramic material. The edges of the terminals are sealed by a head t of glass which also seals the junction 25 between the diaphragm and the terminals. Within the space enclosed by the terminals is a suitable quantity of mercury 4 which forms the conducting medium between the terminals. In the manufacture of the circuit closer, the space en- 30 closed by the terminals is evacuated and filled with hydrogen at a pressure of one or more atmospheres which increases the current interrupting capacity of the circuit closer. As shown by the full lines in Fig. 4, the diaphragm 2 is provided with an opening 5 which is submerged in the mercury when the circuit closer is in the current conducting position. When the circuit closer is in the current interrupting position shown in dotted lines in Fig. 4, the opening 5 is 40 above the'mercury, and the circuit between the terminals is therefore interrupted by the insulating diaphragm 2. Due to the construction oi. the circuit closer the interruption-oi the circuit between the terminals takes place in the mercury as the circuit closer is turned so that the opening in the diaphragm approadhes the dotted line position. The above-described construction is typical a, liquid contact circuit closer which is are resilient contact strips 1 which rest on shoulders to on bosses 8 on the side walls oi the housing. As shown in Fig. 6, the contacts are arranged to bear against the side walls of the housing at each end. The portions of the contacts intermediate the ends are bowed inwardly and are normally spaced from the side walls of the housing. The bowed portions of the contacts are provided with spherical projections 9' which fit into a complementary depression III in each of 10 the terminals. The portions 9 and Ill provide a ball and socket connection between the contacts I and the terminals and therefore provide a construction which supports the liquid contact circuit closer for rotation about the axis of its terminals. Since the portions 9 and iii are spherical, the contact obtained between these parts is substantially independent of the alignment of the circuit closer and the contacts. During the rotation of the circuit closer, the wiping action between the terminals and the contacts tends to prevent increase of contact resistance. The same support for the circuit closer would be provided if'the projections 9 were formed on the terminalsl and the depressions III were formed in the contacts 1. At one end of each of the contacts is 'a flange II into which is threaded a terminal screw I2 for clamping a line conductor to the contact. The flanges II extend through openings in the side walls of the. housing over bosses I 3 which are provided with clearance holes it (see Fig. 5) for the terminal screws I2.
When the circuit closer is between the contacts the bowed portions of the contacts are forced outward so that the contacts rest on the shoulders 811. Since each end of the contacts bears against the side walls of the housing, the resilience of the contacts is utilized to efiect the contact pressure between the terminals and the contacts.
For operating the switch, I have provided a handle I5 oi molded insulating material which fits over the top of the liquid contact circuit closer. The handle is provided on its under side with a groove I6 which fits over the-glass bead 3 and prevents lateral displacement oi the handle relative to the circuit closer. 0n the under side of the handle are projections II which fit in depressions l8 in the terminals I and prevent relative rotation between the handle and the circuit closer. The handle is held in place by a pair of spring strips I9 which extend over the curved flanges 20 on either side of the handle. On the flanges 20 are projections 2| which cooperate with the spring strips and resiliently hold the placed within the depressions handle in either of its extreme positions. The spring strips are provided with stops 22 which cushion the movement of the handle so thatthe movement of the handle to either extreme position is not accompanied by a sharp noise due to the impact of the handle with a stationary part. The spring strips I9 are riveted to a support or mounting strap 23 which is secured to the housing 6 by means of screws 24a threaded from the under side of the housing. The mounting strap provides' a means for mounting the switch in an outlet box. -When so mounted, the right-hand end of the mounting strap 23 should be at the top of the outlet box.
Besides holding the handle I5 in place on the liquid contact circuit closer, the spring strips I9 also force the-circuit closer toward the bottom; of the housing 6. Due to the socket connection provided between the contacts 1 and the ter minals i, this downward force increases the contact pressure between the contacts I and the terminals.
Since the contacts I are adjacent the side walls of the housing, spreading of the contacts is prevented, and this force does not displace the contacts 1 relative to the terminals. The contacts I are clamped against the bosses i3 and the shoulders 8a by strips 24 of insulating material arranged between the mounting strap 23 and the upper surface of the contacts. As shown in Figs. 1 and 2, each of the strips 24 rests against a boss 25 on the end wall of the housing and one end of the strip rests against the end 26 of one of the side walls of the housing. The strips 24 are therefore prevented from twisting when the mounting strap is secured to the housing. With this arrangement the contacts are securely held in place in the housing without the use of inserts molded into the housing.
In the assembly of the switch, the terminal screws l2 are attached to the contacts I. The projecting portions 9 of the contacts are then iii in the terminals I. The handle I5 is then placed on the liquid contact circuit closer so that the projections H of the handle fits within the depressions B in the terminals. The assembled parts are then inserted through the open end of the housing. The strips 24 are then inserted in the housing and the mounting strap 23 is attached to the housi holding the parts in assembled relation. A coverplate 21 may be attached to the mounting strip.
In the use of the switch, the switch is mounted in an outlet box by means of the mounting strap 23, the right-hand" end of themounting strap being located at the top of the outlet box. When so mounted, vertical movement of the handle l5 causes the liquid contact circuit closer to be rotated about its axis. When the handle llis in the raised position, as shown in full lines in Fig. 4, the opening 5 in the diaphragm 2 is submerged in the mercury, and an electric circuit is completed between the terminals I through the mercury. When the handle is in the lowered position, as shown in dotted lines in Fig. 4, the opening 5 is raised out of the mercury, and the circuit between the terminals I is broken. The handle is resiiientlyheld in either the raised or the lowered positions by the engagement of the projections 2! with the spring strips is. It is apparent that by changing the location of -the opening 5 in the diaphragm 2, or by changing the position of the depressions It, the switch can be adapted for mounting in other than vertical positions.
