CONTACT BREAKER.
Application filed August 24,
To all who-m 2'2? may concern..-
Be it known that I, ANDREW Gincnn'rs, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Contact Breakers, of which the following is a specification.
This invention relates to new and useful 'have sliding or wiping action with each other, with the result that they will be kept clean, and a good connection provided at all times.
Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.
In the drawing:
Figure 1 is a side elevation of a portion of the make and break portion of a buzzer, or the like, showing the invention with the armature in elevated position, as drawn up by the magnet;
Figure 2 is a similar view, but showing the armature as havin fallen away from the magnet.
Figure 3 is a vertical transverse section on the line 33 of Figure 1.
Referring particularly to the accompanying drawing, represents the usual electromagnet, mounted on a suitable base 11, and having the projecting core 12. Mounted on the base 11, adjacent the end of the core 12, is a yoke 13, the arms 1% of which extend vertically upward at opposite sides of the core end. Disposed between these arms 14:, and pivot-ally supported thereon, ior swinging movement toward and away from the core end 12, is a metal block 15, which forms the major portion of the armature. ll lounted on the rear face of the armature block 15 is an insulated member 16, the same having a vertical channel 17 formed therethrough. Also mounted on the base, rearwardly of the armature block, and in position to serve as a rear stop therefor, is a block 18, through which is threadedly engaged a vertical screw 1921, Serial No, 494,815. Renewed March 5, 1925.
19. Secured to the rear face of the block 15, and extending vertically thereabove, is a spring finger 20, the same being mounted for flexing adjustment toward and away from the block by means of the screw 21, which is disposed through the spring and block. The upper end of the spring finger 20 is bent to present its convex face toward the rear, as clearly seen in Figure 1, and slidably disposed through the channel 1'? is a spring member 22, the intermediate portion of which is 'formed with a slight how, 22, to bear against the walls of the channel, whereby the spring member will be frictionally held within the channel, but permitted to slide therethrough, in a manner, and io'r a purpose to which reference will be made later herein.
lhc upper end of the spring member '22'is bowed in a direction opposite to that of the corresponding end of the springfinger 20, and in position to move into sliding contact therewith. ihe lower end of the spring member 22 is formed with an angularly turned foot 23 which is adapted to engage with an inclined block 2-1- mounted on the base 11, directly therebeneath.
lllounted on a support, carried by the base 11, and at one side of the support of the screw 19, is a ball-headed screw 25, which is constantly and metallically in contact with the socketed end of a metal arm 26, secured to the. rear of the insulated member 16, and extending laterally there from. A wire 27 is connected to the screw and leads to one side of a source of current (not shown). A wire 28. connects the other side of the source with the electromagnet, while a wire 29 leads from the coils of the magnet to the pivot of the block 15.
When the circuit through the battery, or source of current is closed, it will flow through the magnet, the armature block, the contacting ends of the spring members 20 and 22, to the metal arm 26, with which the spring member 22 is in metallic contact, and back to the source. Upon this completion of the circuit, the magnet will be energized and the armature. drawn up to the core, with the result that the foot 28 will engage with the lower end of the screw 19. This engagement of the foot with the screw, and the movement of the armature toward the magnet core, causes the spring member 22 to he slid down through the channel 17, so as to withdraw its upper end from contact with the upper end of the spring finger 20. The circuit is then broken between the spring members, when the armature will tall away from the magnet. As the armature falls back, the not 23 contact, with the block with the re suit that the spring i'nember is again pushed up through the channel until its upper end contacts with the upper end of the spring linger 20. This action is repeated as long; as the circuit is ClUS through the battery and magnet, The arm 26 remains in constant contact with the ball-headecl screw so that current can readily flow through the spring member 2;
lVhat is claimed is:
1. In a make and l real: means for an electro-magnet an arn'iature mounted for movement toward and away from the mag; net, a s' 'iring linger on the armature and in metallic cont ct thercwitln an insulated member carried by the armature and having a channel tlierethrnugi'h, a sliding'spring; finger trictionally supported in the channel and movable into engagen'ient with the first spring finger upon movement ol the armature away from the magnet, and into contact therewith when the armature moves toward the magnet.
A make and break device for an electro-n'iagnet including a planter armature, a channeled insulating men'ibercarried by the ari'nature, a stationary spring finger on the armature, a ifi-ictionally held spring linger slidable through the channeled insulating member mto and out 01 contact with the stationary finger, a .ioot on the slidable finger, means for engagementby the foot of the sliding finger for moving said finger into contact with the stationary finger and means engageal'ile with said. foot for moving said movable finger awa from said fixed finger.
In a make and break mechanism, an electric magnet, a movable armal'i ure associated with the magnet, a lined contact linger mounted on said armature, a s'second contact linger mounted on the arn'iature, insulated means for slidably attaching said last mentioned contact finger to said armature means for actuating said last mentioned contact linger to contact with said other emit-act finger when said armature is away from said magnet, and means tor limiting the movement of said second contact linger to break the contact between said lingers when said armature is drawn up by said n'iagnet.
4;. The combination with the movable armature of a magnet; of a relatively mow able contact member carried thereby, an in sulated support tor said member. means for establishing an electrical connection between said contact member and said armature when the latter is away from said magnet and positive means for breaking said electrical connection upon movement ot' said armature towards said magnet, said last mentioned means including an abutment adapted to intercept and limit the travel oi, said movable contact member with said armature.
In testimony whereof I allix my signature.
