Specification ofr Letters Patent.
Patented Aug. 28, 1917.
Application led October 17, 1912. Serial No. 726,262.
To all whom it may concern.'
Be it known that I, ERNST G. K.Y ANDER- soN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Switch-Containing Electric-Lamp Sockets, of which the following is a full, clear, concise, and exact descrip.-
tion, reference' being had to the accompanying drawing, forming a part of this speci-A the like.
:A switch-containing electric lampl socket Y constructed in accordance with my invention, is described in the following specification', and shown in the accompanying drawings; but it is to be understood that the invention may be embodied in other forms than that shown and described, without eX- ceeding the scope thereof as defined in the appended claims.
In the drawings:
Figure 1 is a longitudinal section through the device, with the switch in its on position, the section. being taken on the line 1 of Fig. 2;
Fig. 2 is a plan of the device;
Fig. 3' is an inverted plan of the same;
Fig. 4 is a perspective view of the switch and switch contact;
Fig. 5 is a sectional view of the base, showing the manner of mounting the center contact, the section being ,taken on the line 5-5 of Fig. 2; and f Fig. 6 is a view showing the switch 1n its off position. r
Likev reference characters refer to like parts throughout the following specification and the several figures of the accompanying drawings.
Referring now to the drawings, 10 indicates an insulating base in the lower end -whereof, to one side of the center, is formed a chamber 11. This chamber extends a considerable distance up into the base and serves to contain the switch; it connects with the exterior of the base through a passage. 12, through which the switch lever extends into a position convenient for manipulation. A. threaded lamp--terminal-engaging contact 13 1s attached to thelower end of the base bv means of screwsl 14, which pass downward through the base and enter nuts within the latter. Besides the chamber 11, the base is also formed with a recess 15 (Figs. 3 and 5), 1n the bottom of which lies the bent-over end 16 of a metallic strip, the outer end of which is also bent over, to form the center contact 17 .l y
The center contact 17 is secured in place by means of a screw 18, which passes upward through the end 16 andthrough thel base, and enters a binding terminal 19 at the upper end of the base. rl`he upper end of the base also carries a second binding terminal 20, which is held in pla-ce by a U-shaped contact 21, which lies in the upper end of the chamber 11, and has legs 22, which extend through the upper part of the base and through the terminal 20, being bent over beyond the latter (Figs. 1, 2 and 4). The
switch contained in the chamber 11, makes connection between the contact 21 and the threaded contactlS and thus completes the circuit from binding terminal to binding terminal through the lamp. The base may be formed with a side channel 40, leading to the binding terminals 19 and 20; so that conductors may be conveniently led to the binding terminals when the device is used as an angle socket.
The sides of the chamber 11 which are parallel, are formed with oppositely disposed, vertical grooves 23, for receiving the ends of a pin 2-1, which supports the switchmember and the actuating lever. The pin 21 is normally located by means which will be described below, with its ends in the upper ends of the slots 23. Mounted on the pin'24 is a switch contact 25, being a pair of laterally separated, ldownwardly extending legs 26, through which the pin 24 passes.
Portions of the legs 26 are bent over toabutments 28, the ends 31 and 32 of the recess 30 forming shoulders, which engage the abutments 28 when the lever is moved toward the on position of the switch or the of position respectively.
A metallic plate 33 (Fig. 3) is clamped between the base 10 and the threaded contact 13, in electrical connection with the contact 13, this plate having ears 34, through which the screws 14 pass. The plate 33 is formed with upwardly-jogged, outwardly-extending spring fingers 35, which press upon the lower ends of the legs 26 of the switch contact 25. These fingers thus resiliently hold the contact 25, pin 24 and lever 29 in the position, in which the ends of the pin 24 engage the top ends of thes lots 23. v
When the switch is in the on position (Fig. 1), the upper end of the switch contact 25 engages the contact 21, and the lower end is engaged by the spring fingers 35. If, now, the outer end of the switch lever 29 is raised, the shoulder 32, being moved into engagement with the abutments 28, will force the switch contact backward, about its pivot, out of engagement with the contact 21. The ends of the legs 26 of the switch contact have beveledfaces 36, thus forming corners which depress the spring fingers 35 somewhat, during the rocking action described above. When their corners have passed their central position with respect to the fingers 35, the fingers cause the Contact 25-to snap the rest of the way, into the off position shown in Fig. 6. During the movements of the switch contact 25 into its onl and off 7 position, it, together with the pin 24 and the lever 29, will be depressed somewhat, owing to the engagement of the front edge of the switch Contact with the fiat surfacel of the contact 21. The depression of these parts is permitted by the resiliency ofthe fingers 35, which, it will be remembered, support the parts in question in position.
"rhen the switch is to be moved into the on position, the lever 29 is depressed; s0 that its shoulder 31, in engagement with the abutments 28;u will force the switch contact forward into the position shown in Fig. 1. In order to facilitatethe entrance of the upper end of the switch contact beneath the contact 21, the latter is provided with an upwardly-bent lip 37, which guides the switch contact into the proper position.
The switch Vsocket described abovel is simple and reliable; and its construction is such that it .may Vbe placed upon the market at a low cost, and can be assembled and taken apart with ease and speed. By the pro- 1 vision of the twospring fingers 35, I obtain a perfect contact between the switch contact 25 and the contact 21, and avoid anything in the nature of a. line contact.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a switch, a fixed contact, a movable contact, means for so mounting said movable contact that it may be moved 'aboutan axis,
