ELECTRIC SWITCH.

Application filed July 15, 1919.

To all whom it may concern:

Be it known that I, Mormon Gnnr'r, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Electric Switches, which the following is a specification.

This invention relates to electric switches. A switch involving the invention can be employed with advantage in many difi'erent connections; for instance, it may form a part of the equipment of a vacuum cleaner or sad-iron, these being merely two of several illustrations. 1 have several motives in view, among them being the provision of I an article of the character set forth, which can be easily mounted and readily operated. 1

drawings accompanying and fornit of the present specification, 1 have fo h in detail in the following description. I am not necessarily restricted to this particular showing; may depart therefrom in several respects within the scope of the invention d ined by the claims following said descripti eierring to said drawings v Figure l is top plan view of the switch. Fig. '2 is a longitudinal central. section of same, taken on the line 22 of Fig. 1, looking in the direction of the arrows.

3 is a central transverse section on the line 3-8 Fig. 1, looking in the direction of the arrows.

Fig. 4c is a horizontal. practically central section on the line 44 of Fig. 2, also looking in the direction of the arrows.

Lilie characters refer to throughout the several views.

In Letters Patent No. 1,25%,223, granted to me Janua y 22, 1918, and to which reference may he hown a switch possessing some o" a, covered nerebv. i.-- as will be unoer stocd highly is, yet the present switch a complishes r .its not possible by that o; is patent.

The switch involves in its construction a case as 2, which as shown, is of cylindrical f although this is not necessai a Specification of Letters Patent.

e to practice the same will be set like parts Patented A11 24, 1920.

Serial No. 310,934.

primary consideration. The top of the case is denoted by 3 and it is practically in form of a metal disk, having diametrically opposite ears or lugs 4 which match the offstanding lugs 5 at the upperend of the body of the case. Overlaying this top 3 is a cover or face plate 6, through perforations in which and also in the respective lugs d and 5, screws as 7 extend, the screws being in threaded engagement with the respective lugs 5 and acting as a convenient means to hold the top 3 and face plate or cover 6 in position. The face plate or cover has in ad dition holes or perforations as 8 adapted to receive screws or equivalent means by which the switch as a unit may be fastened to a support.

The switch involves a circuit-controlling or switching member. This circuit-controlling or switching member obviously has on and 0d positions. l hen the circuit controlling or switching member is inthe on relation it extends between and electrically bridges contacts or terminals of suitable nature, a form of which is shown and will hereinafter be described. A. circuit-controlling member such as meets my condition is designated by 3 and as represented, is in the form of a metal piece such as eyelet set in and extending thron a carrier as 10. This carrier 10 is pram tically in the form of a segment, having two straight top surfaces as 11 and 12. The segment lO is shown as having extending practically centrally from the upper end thereof, the upstanding ar manipulating portion 13. The arm and the segmental carrier 10, as illustrated, are integral with. each other, the base of the arm, or where it unites with the carrier is rounded some- What to present a hub portion and through the same extends the pivot pin The e elet 9 is headed throu h the carrier 10, at one side of the perpendicular central line of the carrier, there being at. a practically similar distance on the opposite side of the line, a hole or opening 19 which is plain or non-eyeletted.

There are disposed against the lower and upper surfaces of the bottom of the case 2 disks as 20 and 21 of some insulating material having registering holes through which and through holes in the bottom of the case, the studs 22 and 23 extend,,these studs as shown, being interiorly threaded to receive screws as 2% by which wires or like conductors ma be electrically connected to the studs. aid holes in the bottom of the case are largerthan the eyelets or studs 22 and 23 to prevent short circuiting- The terminals of the switch are designated for instance by full and dotted lines in 1 What I claim is 1. An electric switch comprising a case" by 25 and 26 respectively each being practically, of L or angular shape. The forked horizontal portions of the terminals, fit under the'upper flange of the studs 22 and 23. The upright portions of the terminals 27 and 28 which face inward to cooperate with the metallic eyelet or rivet 9 or hole 19. In full lines in Fig.- 2 and also Figs. 3 and 4, the switching or circuit closing member 9 is supposedto be in the operative or on position, the bosses 27 and 28 at this time fitting in the metallic eyelet 9'. To reverse the switch, the actuator 13 is swung over to the dotted line position in Fig. 2, thus moving the eyelet 9 away from the bosses 27 and '28, the motion being continued until the bosses can be projected into the hole 19.

The case 2 interiorly thereof is furnished with projections as 29 and 30 arranged in pairs; and which can be formed by pressing provided with a cover having an opening, a segmental carrier of insulating material in the case, having an :arm integral therewith, the arm extending through the opening in the cover, a pivot projecting through the segmental carrier, at its junction with the arm, the cover having grooves extending oppositely from the opening, and the pin being set in said grooves to thus permit oscilflation of the carrier by said arm, contacts in the case, and a switching member on the carrier, the arm as it. rocks causing the switching member to move between and in e tates engagement with the contacts and then out of such engagement.-

2. An electric switch comprising a case provided with a cover having an opening, a segmental carrier of insulating material in the case, having an arm integral therewith, the arm extending through the opening in the cover, a pivot projecting through the segmental carrier, at its junction with a the arm, the cover having grooves extending oppositely from the slot, and the pin being set in said grooves to thus permit oscillation of the carrier, a rivet supported by the carrier and constituting a-switching member, the arm as it rocks causing the rivet to move between and in engagement with the contacts and then out of such engagement.

3. An electric switch comprising a case provided with a cover having an opening,

a flat segmental carrier of insulating material in the case, having a flat arm integral therewith, the arm extending through, the opening in the cover, contacts in, the case, a switching member on the carrier, a pin proj ecting through the segmental carrier at its junction with the arm, the cover having grooves extending oppositely from the opening, and the pin being set in said grooves to thus permit oscillation of the carrier by said arm, the arm as it rocks causing the switching member to move between and in engagement with the contacts and then out of such engagement, and a-iface plate set against the cover, having an opening through which said arm passes, and means for uniting the face plate and the cover to each other and for also uniting both parts to the case 4. An electric switch comprising a case provided with a cover having an opening, a

fiat segmental earrierof insulating material, in the case, an operating arm for the carrier, rigidly associated therewith and extending through said opening in the cover, a pivot connected with the segmental carrier ap-' proximately at its junction with said arm,

' the cover having means to support the pivot and thus permit oscillation of the carrier by said arm, contacts inthe case, and a rivet supported by the carrier and constituting a switching member, the arm as it is rocked causing the switching member to move between and into engagement with said contacts and then out of suchengagement.

In testimony whereof I afix my signature in the presence of two witnesses a ormon ennrr. Witnesses: l
