ELECTRIC SWITCH FOR LAMP-SOCKETS, 8w.
Application filed April 14, 1915. Serial No. 21,212.
. To all whom it may concern:
easily made attachment which canbe. readthe formation of arcs, and this I do by form ily applied by loosely fitting it to the rotary switch member and which when so applied will cooperate with the other element in effi ciently and reliably opposing or preventing ing and applying theattachment in such a way that while the connection is a loose one, portions-of the appliance will underlie the contacts ofthe rotary member in position for breaking or opposing the formation of arcs while other portions of the attachment will cooperate with the contacts for holding the first mentioned portions in the described position when the rotary member is rotated. At the same time the attachment is additionally kept in its proper location by being interposed between the stationary and rotary spring pressed switch members.
To these and other'ends hereinafter set forth the invention stated in general terms comprises a combination of elements having the form, material and cotiperation hereinafter described and particularly pointed out in the claims.
In' the accompanying drawings, Figure 1 is a side view, drawn to an enlarged scale,
with parts broken away of a socket embody: ing or containing features of the invention.
Fig. 2, is a similar view with parts omit- -ted for the sake of clcarness.
Fig. 3, is a top or plan view, drawn to an enlarged scale, and Fig. 4 is'an edge view,
view of the Specification of Letters Patent.
Patented Apr. 17, 1917.
We will now proceed to describe a novel element and its novel combination with the previously described elements, whereby new results are accomplished or old results are obtained in a better, cheaper and more advantageous manner than. heretofore.
15 is a fiat insulating ring provided with diametrically spaced internal projections or teeth, of which four, 16, 17, 18 and 19 are shown. The ring 15 is combined or assembled with the rotary switch member 4: by placing the teeth. 16 and 17 opposite the de pending ends of the contacts 9 and 9 and then giving the parts a slight motion of rotation. This brings the teeth or projections l6 and 17 under the contacts and the teeth or projections 18 and 19 in abutment with the oiisets 10. Ilhus when the rotary member is .meohe for supporting it in respect to the crowh-tooth member. The rin thus mounted, while loose and capable of some play, is nevertheless kept in its proper pose i tion by the combined action of the teeth 18 i and 1'9 and the spring pressed elements be Ire tery and stationery tween which it is interposedrthet is, the ropartsj'of the switch. At the some time the contacts 9 and 9- are exposed when viewed from their outside edges as well as when viewed from their F feces and the projections 16 and 17ers in proper position for interrupting or opposing the formation of ores when the co tects 9 and 9 leave the fixed contacts 3 and spring into off-position.
While We have descr'bed thebest embodiment of our'invention known to us etcthe present time, still departures may be made in details without departing from the spirit of the'invention, hence the letter is not limited as to such matters nor in any way further than the prior state of the art and the appended claims may require.
Whet we claim 1S.
1. In an electric switch the combination of a fixed crown tooth member, and a rotary switch member spring-pressed in respect to the crown tooth member and provided with depending contacts cooperating with the teeth of said member, and a flat insulating ring loosely mounted in respect to said members and provided with internal teeth ofmes es which some underlie the contacts and serve to oppose or break arcs and of which others abut on the roots of the contacts to position the first mentioned teeth, substantially as described.
52. In on electric switch the combination of a fixed crown tooth member and a rotary switch member spring-pressed in respect to in on electric switch the combination of a rotary element provided with depending contec i end with offsets, and a flat insuhit ing ring loosely mounted in respect to said member and provided with internal teeth of which some underlie the contacts and serve to oppose or break arcs and of which others abut on the offsets to position the first mentioned teeth, substantially as described.
In an electric switch the combination of s rotary element comprising a hub having diametrically offset arms provided with depending contacts, an insulating disk notched for the passage of said arms and crimped to the hub, and an insulating ring loosely abutting on said disk and provided with. internal teeth of which some underlie the contacts and of which some abut on said arms to position the first mentioned teeth when the disk is rotated.
In testimony whereof we have hereunto signed our mines.
