JOHN BERG, OF CHICAGO, ILLINOIS. ASSIGNOR TO METAL SPECIALTIES MANUFACTUR- ING COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.
ELECTRICAL CONNECTER.
Application filed August 31, 1921.
This invention relates particularly to electric connecters such as are used for connecting electric conductors together or for connecting electric conductors to any electrical device, such as an electric lamp. The primary object is to provide a connecter with a switch device of the rotary disk type, which is adapted for use in a single wire system.
The invention may be employed very advantageously in connection with either a dash-lamp or an exploring lamp for automobiles.
The invention is illustrated in its prel5 ferred embodiment in the accompanying drawing in which- Fig. 1 represents a plan view of a dashlamp constructed in accordance with the invention, the dash-lamp being shown applied to a dash which is shown in section; Fig. 2, a bottom plan view of the device; Fig. 3, a sectional view of the device as shown in Fig. 1, the section being taken parallel with the plane of the paper and onlythe reflector or shield and its supporting member being shown in section; Fig. 4, a transverse section taken as indicated at line 4 of Fig. 1, the,view showing the rear side of the switch-disk; Fig. 5, a similar section with the switch-disk removed, so that the end of the lamp-shankis exposed; Fig. 6, a sectional view taken as indicated at line 6 of Fig. 2, the view showing the front side of the switch-disk; Fig. 7 a similar sectional view, with the switch-disk removed;
' and Fig. 8, a longitudinal sectional view taken as indicated at line 8 of Fig. 6.
In the construction illustrated, A represents an automobile-dash, which may be assumed to be of metal; B, ametal sleeve or shell supported by said dash; C, an insulation plug mounted in one end of the shell; I). an incandescent lamp mounted in the other end of the shell; E, an interposed oscillatory switch-disk; and F, a shield or reflector mounted on the forward or outer end of the shell B.
The shell B is shown as having its intermediate portion provided with an external flange 1 and having one end portion threaded as indicated at 1, thus affording a shank adapted to extend thru a perforation in the dash, to which it is secured by means of a nut 2. The other end of the shell B is provided with bayonet slots 3 which receive Serial No. 497,100.
the studs 4 of the lamp or bulb D. The shank of the lalnp is provided at its inner end with a central contact 5.
The plug C is composed of insulating material. It is fitted with a pair of spring 00 contacts 6 and 7 which are disposed on opposite sides of the center of the plug. Each of these devices 6 and 7 comprises a sleeve and spring-pressed plunger of well-known construction. The plungers serve as a support for the rear side of the switch-disk E. The device 7 is in reality a dummy contact. With the contact device or terminal 6 is connected an electric conductor 7.
The switch-device E comprises an insulation disk 8, a handle 9; and eccentrically disposed contact-posts 10 and 11 which extend thru the switch-disk and have their forward ends connected by a thin metal plate 12 whose central portion makes contact with the central contact 5 of the lamp.
One of the contact-posts, that is, the contact-post 11, may be regarded as a dummy, so far as the circuit is concerned. The handle 9 has a reduced stem 9 which extends transversely thru the shell and works in segmental slots 13 with which the shell is provided, the stem also extending thru the central portion of the switch-disk. The slots 13 are provided at their end portions with oiise'ts, recesses or bays 13 in which the stem of the handle snaps when the switchdisk is at either end of its oscillation.
It will be understood that the plungers of the spring contacts 6 and 7- serve to press the switch-disk firmly against the central terminal of the lamp; also, that the pressure of the plunger device 6 serves to establish good contact with the contact-post 10.
The central contact 5 of the lamp remains always in contact with the contact-plate 12. When the switch-disk is turned in one direction, it establishes contact between the contact-post 10 and the spring-contact 6 in the manner shown in Fig. 8. When the switch disk is rotated in the opposite direction, it carries the contact-post 10 away from the contact-device 6, thus interrupting the circuit. It will be understood that when the handle 9 is swung to either end of the slots, the stem will be caused to snap into the corresponding recesses 13*, owing to the fact that the spring-pressed plungers of the devices 6 and 7 press against the rear side of the switch-disk.
The improved device is simple in construction, may be readily assembled, and is easy and certain of operation.
The foregoing description has been given for clearness of understanding only, and no unnecessary limitation should be understood therefrom, but the appended claim should be construed as broadly as permissible in view of the prior art.
lVhat I regard as new, and desire to secure by Letters Patent, is
A device of the character set forth, comprising a shell provided at one end with bayonet slots and provided medially with a lateral segmental slot, a plug in the other end of the shell equipped at its inner end with a pair of spring-pressed contact plungers, a conductor connected with one of said contact plungers, a switch-disk equipped With a handle extending through said segmental slot, said switch-disk having contact posts extending through it and adapted to engage said contact plungers, said contact plungers serving to exert a balanced pressure against said switch-disk, and a contact plate connecting the front ends of said contact posts and adapted to bear centrally against a center contact of a lamp held by said bayonet slots.
