Specification of Letters Patent.

Patented @ct. 17, 1911.

Application filed September 26, 1907. Serial'No. 394,698.

accom ninying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to electric switches and has for its object to provide a switch for closing an electric circuit by an independ ent circuit, such as for instance an arc cir-' cuit, in such manner that. an independent electric circuit can be closed by an are or other circuit for the purpose of lighting alleys, streets, road-ways and'the like.

ll'ith this object in view my invention consists in the novel construction of the switch and also in certain combinations of parts all of which will be first fully described and afterward specific-all}, pointed out in the appended claims.

Referring to theaccompanying drawing: Figure 1 is a verti *al sectional view taken through the coil or solenoid showing switch also in section. Fig. 2 is a diagrammatic view showing the winding of the coil or solenoid. Fig. 1-3 is an elevation showing the coil and switch and illustrating the casing or covering in vertical section. Fig. 4r. is a top plan view of one or the blades of the switch. Fig. 5 is a-top plan view showing a switch having two blades. Fig. (3 is an end view of one of the switch blades and hinged connection. and, Fig. 7 is an end view of the flexibly held contact plate.

Like numerals o'l ret'crence ilulicate the same parts throughout the several figures in which: 7 y 1 indicates a plate or wall constructed preferably of iron forming a base for the entire device, said plate or wall being prt'ivided. with a slot 2 through which a bolt 3 passes and a perforation a through which a similar bolt 5 passes.

6 indicates the hood ,or cover which may be constructed of any suitable material and of a forni as shown in Fig. l, in order to protect the device when the same is used out or" doors.

I 7 indicates the coil or solenoid which has a double winding as shown in the diagran'imatic view, Fig. 2. 'ithin the coil or solenoid 7 I provide a fixed magnet 8 which is constructed preferably of sheetsor layers of soft iron, and within the core of the coil I provide a movable magnet 9 having an extending'rod 10 which passes out of the core and has its end connected to the switch 11 as shown in Figs. 1 and The switch 11 can be constructed as shown in Figs. 1 and 3, or it may be constructed as shown in Fig. 5, in which instance the rod 10 is connected to an insulated bar 12 which connects the arms or blades 13 of the switch 111 The coil or solenoid 7 is preferably 'supported on a bracket 14 having a guide plate 15 at the top thereof in order to securely hold the coil in position. The bracket .1; is provided with two depending arms 16 to which is secured a base plate 17 of slate or other insulated material. base plate 17 is the switch 11, each arm or blade of the switch being connected to the hinged member 18 as shown in Figs. 4 and (3, said hinged member 18 being securely screwed or bolted to the base plate 131.215; shown in Fig. 1. one of the bolts 19 serving as a binding post to which is connected one of the wires 20.

Arranged under the base plate 17 is a plate 21 securely bolted or screwed thereto, and a slot or openin 22 is provided in said plate 17. r

23 indicates a contact plate secured to two vertical posts or bars 24, each of said posts or bars being provided with an enlarged/head and having a coil spring 26 of compression strain which normally holds said plate in position shown in Fig. 1. A

flexible connection 27 passing from the piate.

23 to the plate 21 insures a. good contact and prevents arcing. -lhe wire 28 of the inde pendent circuit is connected to the plate 21 preferably by means of a bolt or screw 29.

The rod or bar 10 of the movable magnet 9 passes through the base plate 17 and is provide- 1 with an adjustable collar 30 which is provided on said bar or rod 10 to limit the downward movement of the movable magnet 9.

As shown in l 1 and 3 a flexible connection is provided bet-ween the arms or blades 13 of the switch and the hinged member 18 in order to secure a good contact to prevent. arcing. The arms or blades 13 of Secured to the the switch 11 are given a quarter turn in i order to present a hat surface to accom1nodate a spring contact piece 31 as shown in j the drawings. Having thus described the severalparts of my invention its operation is as tollowszl Thearc or other circuit passes through the l coil or solenoid 7 energizing the fixed magt not 8 thus drawing/the movable magnet 1) toward the fixed magnet S. This movement of the movable magnet 9 is comtnuniczited by means of the bar or rod 10 to the switch 11 drawing the switch in an upward direction and -ausing the spring contact 31 on Y the arms or blades 13 of the switch 11 to be brought in contact with the contact plate 23. v The circuit thcn passes through the arms or blades of the switch, through the contact plate 23, flexible connection 27 and plate 21, thus closing the independent circuit which is Wired as shown at 20 and 28. l Any variation in the are or other circuit which passes through the coil or solenoid T t will of course vary or alter the height or position of the movable magnet 9 within the core of the coil or solenoid. As a matter of fact there is a sudden variation which causes an oscillating or vibrating movement of the movable magnet 5). Should this oscillating or vibrating movement be communicated to the switch of usual construction considerable noise and rattling would result. 1y the construction just described, however. this oscillating or vibrating movement ol" the movable magnet t) is ltlkOll care of by i the spring held contact plate 2:3 and the, spring contact 31 on thc.s\vitch arms or{ blades 13, said spring contact 31 oscillating over the surl'ace of the contact plate 2 3 and wiping the same upon oscillatonv movement ol the magnet and switch. The extent. of mmcment being clearly shown in dotted lines in l i 3, thus providing a tlexible or resilient switch which can be actuated by an independent circuit without any attendant l rattling or noises.

Having thus fully described my invention what I claim as new and desire to secure by Letters Patent of the United btates, is:

l. A switch of the character described comprising a solenoid having therein a fixed magnet and a movable magnet, a base plate under said solenoid, a pivoted switch arm associated with said base plate, a resiliently held contact plate under said base plate, a

spring contact on said switch arm adapted to engage the said resiliently held contact. plate, means for connecting said movable magnet with said switch arm to communicate the movement of said movable magnet to said switch arm, said resiliently held contact plate being arranged in the path of movement of the spring contact on the switch arm in such manner as to be engaged and wiped by the same, the spring contact on said switch arm being resilient and Wiping over the face of the said resiliently held contact plate upon movement of the said switch arm controlled by the said movable magnet within the said solenoid.

2. it switch ot the character described, comprising a coil or solenoid having therein a fixed magnet and a movable. magnet, a base plate of insulating material under said coil, a plate of conducting material on said base plate, a resiliently held contact plate carried by said plate of conducting matcrial, a switch arm under aid resiliently held contact plate. a spring contact carried on said switch arm, a connection betwveen aid movable magnet and said switch arm for communicating the movement o'l said movable magnet to said switch arm to raise said spring contact thereon into engagement with tlltl resiliently held contact plate, subi stantially as described.

in testimony whereol I allix my signature, U1 presence ol two witnesses.
