SWITCHING APPARATUS.
Appflication filed February 23, 1921. Serial. No. 447,114.
or circuit breaker structure for controlling or protecting electric circuits carrying current for power, lighting or other purposes.
In accordance with my invention, circuit breaker structure, may be tripped manually or otherwise than automatically by means operated or controlled by a door or movable wall of a housing in which the circuit breaker structure is enclosed, as upon movement of such wall or door to position to allow access to the interior of the ,housing.
In accordance with my invention, the circuit breaker structure may be tripped manually or otherwise than automatically by means operable from the exterior of the housing, and in addition to the above mentioned tripping means operated or controlled by the housing wall or door.
In accordance with my invention, the circuit breaker mechanism may be both manually or automatically tripped and reclosed or reset by novel structure of the character hereinafter described.
My invention resides in features of structure and combination hereinafter described and claimed.
For an illustration of some of the forms my invention may take, reference is to be had to the accompanying drawings, in which: I 4

Fig. 12 is a fragmentary side elevational view, partlyin section, of a modified form of tripping mechanism.
part of one of the tripping Figs. 13 to23 inclusive are views of dif ferent parts of said modified form of tripping mechanism.
Referring to the drawings, upon a base 1, of suitable insulating two switch, or circuit breaker mechanisms, A. and B, Fig. 2, the description of the parts of one of which will suflice .for both.
As indicated in Fig. 5, each circuit breaker comprises the main contact terminals 2 and 3, adapted to be connected or bridged by the bridging contact member 1, each circuit breaker being provided with an overload or other tripping. coil 5. As indicated the tripping coils are in series with the circuit breakers, one circuit breaker and its tripping coil being connected in each side of a supply circuit. For example, as indicated in Fig. 5, the two supply conductors 6 and 7 connect with the upper main terminals 2, and the lower ends of the tripping coils 5 communicate with the consumption circuit conductors 8 and 9. It will be understood, however, that the breakers may be otherwise connected in circuit, .as for example, in series with each other in one and the same side of a circuit.
The main terminals 2 and 3 are secured upon the base 1, and the laminated bridging member 1 is carried by an arm 10 pivoted to the bracket 11 at 12. Pivoted to the arm Mat 13 is a toggle link or member 14 pivoted at 15 to the toggle link 16, pivoted at 17 to the housing or bracket 11 secured upon the base 1. The toggle link 14 may, as indicated, take the form of a plate or plates 18 carrying the pin or roller 19 and also the pin or roller 20, which is engaged by the hook latch 21 pivoted to the housing 11 at 12 concentrically with the latch actuator 22 having the tail "23 adapted to be engaged and shifted by the-arm 24 carried on thearmature 25, pivoted at 2'6 and co acting material, are secured with the poles 27 27 of the electro-magnet whose winding is 5. The latch actuators 22 of the two breakers A and B are con nected together by the transversely extending bar 28, whereby, by actuation of either latch actuator 22, either automatically or manually, the latches 21 of both breakers will be actuated to release them and allow their movable contact members to fly to open circuit position.
As well understood in the art, upon occurrence of overload or other predetermined electrical condition, the armature 25 will be attracted to the poles 27, 27, causing tripping of the circuit breaker structure, in which case the under-travelled toggle structure 14, 16 will collapse, the arm 10 rotating in clockwise direction, Fig. 1, carrying the movable contact member 4 away from the main terminals 2 and 3. Accompanying this movement, the rollers or pins 19 of both breakers A and B will be in elevated position, as indicated in Figs. 3 and 4.
Secured to the base 1, or otherwise suitably supported, is a housing or box H enclosing the circuit breakers A and B and having the movable wall or door D. When the wall D is a door, it may be hinged, as at its upper edge, to swing outwardly about a horizontal axis to allow access to the mechanism within the housing H.
Carried upon the wall D is the plate 29 having the inwardly extending bracket 30 having at its end the boss or hub 31 forming a bearing for the shaft or rod 32, which partakes of both rotary and longitudinal movements. Secured in fixed position upon the shaft 32 is the hub 33 having the upstand-.
Upon the exterior of the wall D is secured a member 45 in the form of a staple or equivalent, adjacent which comes the end 46 of the bracket 41 when the latter is in its mid or neutral position. Through the members 45 and 46 may be slipped a locking member, as a padlock, whereby the shaft 32 cannot be rotated by the handle 42 to set or reclose the circuit breakers, though they may be tripped by pushing inwardly upon the button 43.
Pivoted at 47 on the upward extension 48 of the hub 31 is the tripping member 49 hav ing a lug 50 adapted to be engaged and actuated by the inner end of the shaft 32'and having an end 51 adapted to engage and actuate the bar 28 connecting the latch actuators 22.
Accordingly, by pushing inwardly upon. the button 43, the shaft 32 is moved inwardly to actuate the member 49 upon its pivot 47 to engage and actuate the latch actuators 22 to trip the circuit breakers; the movement of member 49 is limited by the stop 48 on member 48.
The circuit breakers may be reset by rotating the handle 42 first in one direction to cause the member 35 to actuate the pin or roller 19 of one of the breakers downwardly, extending its toggle mechanism and moving it to latching and circuit closing position. The handle 42 is then rotated in opposite direction to similarly reset or close the circuit breaker, the spring 37 opposing movement of the member 35 from its neutral or mid position and restoring it to such position upon release of the handle 42.
Pivoted to a wall of the housing H or other suitable support at 52 is a second tripping member 53, whose end 54 is adapted to engage and actuate the bar 28 and thereby actuate both latch actuators 22 and through them the latches of both circuit breakers to trip them. The angular movement of the lever 53 upon its pivot 52 is limited by the pin 55 carried by the housing or other sup port and extending through the slot 56 in the lever 53. Carried by a movable wall or door, as D, is a bracket 57 carrying a roller 58 co-acting with the dog 59 pivoted at 60 to the tripping lever 53, the dog 59 having a tail 61 laterally extending and adapted to engage the laterally extending ear 62 on the lever 53.
If the wall or door D be moved, as outwardly or towards the right, Fig. 1, the roller 58, moving therewith, engages the end of the dog 59, whose counter-clockwise rotation upon pivot 60, Fig. 1, is limited by the tail 61 engaging the ear 62, thereby causing the dog and the right .nd of the lever 53 to rise. whereby the lever 53 rotates in counterclockwise directiou, Fig. 1, upon its pivot 52. and brings its end 54 into engagement with the bar 28, thereby tripping the breakers or either of them which may be in closed position.
the case where the wall D Accordingly, access to the housing is not obtainable without first tripping the break- .ers or either of them which may have been left in circuit closing position. In reclosing the door or wall D, the roller 58 will engage the lower end of the dog 59, which will idly rotate in clockwise direction upon its pivot 60 until the roller 58 has passed, whereupon the parts'again assume the position indicated in Fig. l.
As a modification of the tripping member 53 and its associated parts, there may be employed the structure indicated in Figs. 12 to 23 inclusive, wherein the tripping lever 68, pivoted to the housing at 64, has a pin and slot connection with the longitudinally movable bar havingthehead 66, the bar 65 being carried in the bracket members 67 and movable toward the right in opposition to the spring 68. Pivoted at 69 on a bracket 70 carried by the door or wall D is the dog 71, whose upper end 72 rides under the bracket 73 and whose lower end 74.- is adapted to engage the head 66 of b-ar 65.
In moving the door or wall D toward the right, Fig. 12, the lower end of the dog 74 engages the head 66 and pulls the rod 65 toward the right in opposition to springs 68, the bracket 7 3 preventing rotation of the dog 71 during this action. The rod 65 causes the lever 63 to engage the bar 28 andso trip the circuit breakers or any of them. Eventually, the end 72 of the dog 71 rides past the bracket 73 toward the right, whereupon the dog 71 exerts no further influence upon the rod 65, which is accordingly restored to normal position by the spring 68. door I), the lower end of the dog 74 will ride over the head 66, the dog rotating in counter-clockwise direction upon its pivot 69 in so doing, and will again engage under the bracket 73.
In general, it will therefore be understood that in case of overload on either side. of a circuit, one or both of the electro-magnets 5 will be energized, causing tripping of both breakers.
The breakers may be reset, as previously described, by operating the handle 42 first in one direction and then in the other. The breakers may be. manually tripped by pushing inwardly upon the button 43 to actuate the tripping member 49, which latter does not rotate. with the handle '42 and member 35, but is actuated only upon longitudinal movement of the shaft 32.
l urtherinorc, when access to the interior of the housing sought, the breaker mechanism is tripped upon movement of the wall or door D by means independent 6f the above mentioned manual tripping means.
It will be understood that my invention, as to some aspects thereof, is not limited to In reclosing the wall or is movable, but
includes also the case where the wall D is fixed as regards the housing H, and the housing H as a whole movable or removable.
