Be it known that. l. Louis. Kommun. a ritizen of the llnitetl States, und a resident oi the borough oi Manhattan, city, county, and State of New York', have ii'iventetl eertain new and useful Improvements in Douhle-1`h|.'ow Snupwitehes, of which the 'following is a specification.
This invention relates to electric switches and, while the drawings illustrate a doublethrow triple-pole switch, it will be olwious that the invention is equelly applicable to switches haring a single throw and to switchee having any desired number oi poles.
Une of the objects of the invention is to providey simple. durable, and e'ective meehanism for operating the terminal bridging means with n rapid or snap action both to make anal hre-.1k the eircuit.
A further important object of the invention is toV provide a. loublethrow awitrh having' a rorking terminal bridging brush formed ot' a plurality of resilient plates of conducting material adapted to make a tlrm and broad Contact with either of two sets of line terminals. g
Another object of the invention is to provide u switch having a rocking terminal bridging (levioe and menne embmlying Single motor spring and'switoh handler for rocking said Lieviee with a snap action to close either of two circuits or to break 'both circuits.
A 'further object of the invention is to provide a switch having terminal bridging means. motor meehanisln for shitting the bridging means with a snap action in opposite directions, means for automatically locking the bridging means in on and olim positions, a swinging;r switch lever, anni means rontrollerl by Suhl. lever for Stor ing power in the motor nieffhauisn'i and soir sequently releasing the hrflning means to permit the motor meehanism to soup the bridging means in a flirevtion eorrrsponeiing with the direction of movement of the levrr.

The rocking, rontaet brushes and the n'ieohanialn for operating the sume. are mounted in liraekets 1 and :2 bolted or otherwise scoured to one fare of a hase ll of Slate. porcelain or the like at opposite sides of' Suhl linee.. The thlree terniinal-ln'illging rontact brushes 4 are confined in a housing romprisingr the base late 3, Side walls or plates intermediate partitione` (l similar to platee and u top wall or plate T. The platee 5. (l and 7 and hase plate tl are rig idly ronnected together b v holte l() which pass through the top nml hase plates and extend ,rertically through apertures in the plates 5 and 6. i
The nietes '5, (i and T lare formed of suitable insulating material and in oonjunrtion with the hase plaie 3 form an ilimilatiiig kruising ilivirleil into three rompartments, one Vfor eat-h brush 4 and its two ossoriatecl paire of line terminals 8 and 9. One ter min-.1l n in fixed to the hase plate 3 adjacent one emi ol' euch compartment am! tlieirarsoriaierl terminals 8 are mounted on the untler side oi' the top plate i at the opposite ends-1 ol! the compartments. (lne terminal 9 is tixell to the hase plate in each rempartment at the opposite end thereof from the lower terminal S am! one termin-.il .l is lixell to the .nder aille of top plato i' in earh rompartlnliit at the opposite eml of 4the romparlnuvit from the upper terminal 4.
The brushes 4 are formell ol a plurality oi' leaves or 'platos of resilient ronilurting metal. the longest. leal' heine in the zniilille of theI ln'ush and the remainingl lomos ilorer1f-ln; f in length toward the toy aiul hot-- #om ot' the lirush. aS shown in Fine. l ami il. The hruwln-e extenzl through apertures in a roc-king lair 1l uml are liehl to sait: har hy euitaiilo holt;` or rivets l2. The inurlhos are said spring contact brushes 4 as described a limi and broad contact is insured between the brushes and the line terminalsoll both circuits, and that the latch bolts will lock the brushes with the ends of the leaves thcreotI pressed under tension on the terminals, the parts being so proportioned that the motor spring will rock the brushesl a sullicient distance to cause the ends` thereof to be deflected as indicated `in dotted lines in Fig. t) betere the power of the spring is exhausted. It will be obvious that the forward latch bolt will prevent reverse rotation of theibrush support and thus lock the brushes in engagement with the terminals while under compression.
if desired, plate 1S may be cut away at the lower portion oi' the opening 1'.) opposite the stops M- to form a segmental recess 4T terinlnating in. abutments or stop shoulders Lt8 adapted to be engaged by a stop lug 4U on disk 2U to limit the extent ot' rotation of the disk and insure engagement oi the latch bolts with the two end stops 24 even if the latch bolts should become somewhat sluggish in operation. A spring-pressed retarding plunger 5() may be held to plate 18 midway oi the segmental. recess t7 to engage the lug 1U on disk 2l) and thus retard the final movement of the from either on position. r1`he stop lug 49 recess 4J and plunger 5U are not essential however, and may be omitted.
