FEED-THROUGH SWITCH.

Specicaton of Letters Patent. PatQnted Oct. '12, 1920.

Application lled March 13, 1918. Serial No. 222,072.

To @ZZ whom it may concern:

Be it known that I, RALPH A. BELMONT, of New York, in the county and State of New York7 have invented a new and useful Feed-Through Switch, of which the following is a specication.

A feature of my invention is that the switch is mounted on a support which is separate from the casing, one of the advantages of this construction being that if the switch burns out the casing is still available for use and another of the advantages being that the wiring is very easily done, the wires being connected to the support' and then the casing applied.

Another feature of my invention is a casing which is split; preferably longitudinally, and which surrounds the switch and is held thereto.

Another feature consists in fastening means at both end s of the casing and preferably I use means which can be snapped in place, such as split rings. i

Another feature consists inl providing a neck or necks to surround the conductors, the neck or necks preferably cooperating with thefastening means. Y"

Other features will be pointed out Qelow.

Figure l is a plan of my switch with the casing applied;

Fig. 2 is 'a plan with one casing member Fig. 3 isa reverse plan ing member removed; y Fig. 4 isa plan of the support;

Fig. 5 is a central vertical section;

F ig. 6 isa vertical section on line 6--6 of Fig 3; .I t y Fig. 7 is a plan of the movable contact;

Fig. 8is an elevation of the movable contact; and f 'Fig 9 is an elevation of the' Vswitch with the casingapplied..

4The supportAffor the iixed and movable contacts is a Isubstantially cylindrical block of porcelain or other vinsulating material cut away atja and a so as not to interfere with the pushbutt/xons and also having depressions a2 and a?" adjacent to the fixed contact screw headshereinafter described so as to permit the ends fof thel movable contact to sink slightly. asthey approach the fixed contacts and thus make a very efficient contact. Support A` has a recess to. receive a metal plate with the other casscrew acting as a fixed contact.

- ber H is crimped at L and h2 to ends great resiliency so that they will eili- B which'has a wall at one end having an upper portion b 'and a lower portion b, these portions being spaced to receive the actuating bar hereinafter described. At the other end of the plate is a similar wall having-up- -per portion b2 and lower portion b3. The

metalplate has a slot b4 and holes b5, b and o7 to coperate with other parts described below, holes b5 and o7 being threaded. On the reverse face of support A are depressions d and d to receive the heads of screws D and D', which screws pass through the support, the former engaging threaded hole b5 and the latter engaging threaded. hole 57 to hold the metal plate B in place. The reverse face of the support is depressed at d2 to permit ready manipulation of wire E in attaching the latter to the binding post E which is carried by plate E2, the latter being held in place by means of threaded connection with the shank f of a screw which passes through the support or base A, the head F of the Similarly the reverse face is depressed at d3 for manipulation of wire G in attaching the latter to binding post G which is carried by plate G2, the latter being held in place by means of threaded connection with the shank g of another screw which passes through the support, the head g acting as the other fixed contact. 4

The movable contact member H has a stud riveted to it the shank h of which enters hole be vand acts as a pivot for the member H. Near the contact ends the memgive the ciently engage .the xed contacts.

The push buttons K and K are cut away as shown so as' not to strike the support and they are mounted .on the ends' of bar K2 which is guided between'theupper portions b and b2v and the lower portions lb and b3, said bar being provided with depending lugs 7c and. k which engage the walls of the metal plate B' to limit .the movement of the bar K2.

A coiled bow spring M has one.end m passing through themovable Contact member and, hooked or bent 'thereunder the -Yhooked portion riding in slot b4. The other end m ofthe spring is curved around and hooked into the bar K2 and when the bar Kz is pushed upward in Fig- 3 end m of the sprmg is carried upward and when said end v-movable contact will be actuated out of engagement with the fixed contacts and the reverse movement of the bar K2- Will givev reverse movement to the movable contact. i It will be clear that .the lined and movable contacts are mounted on the support or base and the wires E and G connected thereto, the wire N resting along the edge of the support, the structure thus forming a complete entity apai't from the casing which is split Vlongitudinally to form two members P and P, the flat face p of member'P engaging the flat face p of member P. Member P has a neck portion 292 at one end and 'p3 at the other end, member P having similar neck portions p4 and p5, the portions p2 and p5 coperating to surround the conductors at one end. of the device while the portions 273 and p* coperate'to surround the conductors at theother end of the device. Member P is grooved at p and 29T-to receive the split rings described below and has a deep recess pff to receive the springM and has also a raised circular rib p toenter member l/ so as to prevent relative movement of face p along face p other than ro tary movement. Member P is grooved at p10 and p11 to receive said split rings and has recess p12 to hold the support against sidewise or lengthwise movement and additional recesses p13 and plt to receive the binding posts, space p15 in Fig. 3 receiving the rib p9. y

lVhen the switch parts and the wires have been attached to the support as a separate entity the two parts of the casing arel applied and the split rings R and R are snapped into the grooves of members P and P to hold said members together, the portions ;01 and p oi' rib 71.9 by engagementV with wires'E and G tending to prevent removalof the support from recess p12,

What I claim is:

l, A device of the character described comprising afbase of insulating material;

I therewith.

cludingterminalsare mounted on said base; a longitudinally split casing -for said elements comprising a plurality of parts of insulating material, said switch mechanism" itself being entirely disconnected from said casing; means to hold said parts of theca sing together; an electrical conductor con-' nected to one of said terminals another'electrical conductor` connected to the other of saidterminals; and athird electrical conductor passing through said casing. f

2. A device of thel character described comprising a base of insulating material;

switch mechanism,' all of whose parts including terminals are mounted on said base; a longitudinally split casing for said base and switch mechanism and comprisingv a plurality of parts of insulating material,

3. A device of the character described` comprising abase of insulating material; a-

switch mechanism, all of whose parts including terminals Aare* mounted onv said base; a longitudinally split casing for said base and switch mechanism and comprising. a plural-l ity ofparts of insulatingv material, neither said base nor any part of said switch nechf anism'having any iXed connection with said -casing but being held in place by vsaid cas* ing; lmeans to hold said parts of the casing together; an electrical conductor connected to one of said terminals; another electrical yconductor `connected to` the other of said terminals; and a third electrical conductor which is flexible and covered with insulatingv material and which passes entirely through said casing'but has no fixedbonnectior RLPH A.
