UNITED STATES PATENT JOHN R. BYRNE, OF SOHENEOTADY, NEW YORK, ASSIGNOR TO GENERAL ELECTRIC COMPANY,
A- CORPORATION OF NEW YORK.
PULL-SOCKET.
Specification of Letters Patent.
Patented April 6, 1909) Application filed August 1, 1905. Serial No. 272,216.
To all whom it may concern:
Be it known that 1, JOHN R. BYnNE, a citizen of the -United States, 'residmg at Schenectady, county of Schenectady, State of New York, have invented certain new and useful Improvements in Pull Sockets, of
series of pulls on a-cord or chain; one pull turning on the lamp and the next-pull turning it 0E.
The invention resides in certain details of construction hereinafter set forth and particularly pointed outin the claims.
I In the'accompanying drawing, Figure 1 is a sectional elevation of a lamp socket mechanism embodying m invention, and
showing the circuit open; g. 2 is a similar viewshowing the circuit closed; Fig. 3 is an end view with the screw-threaded lamp receptacle removed; Fig. 4 is 'a side view of part of the mechanism; Fig. 5 is a cross section; Fig. 6 is a perspective view of the frame and spring contact; Fig. 7 is a perspective View of the tumbler; Fig. 8 is a similar view of. the actuator; and ig. 9 is'a side elevation of the entire' socket.
The shell 1 and cap 2 inclose a base 3 of insulating material provided with certain recesses to receive the metal parts. These comprise first, a frame which is preferably a piece 4 of sheet metal having a flange 5 along one edge, a lug 6 at one end, a smaller lug 7 at theother end, and a Y-shaped slot 8, the arms of the Y being preferably'curved, as shown. At one :end 0 the flan e 5 is a depending lug 9 into which is tappe a binding-screw 10 for one line-terminal. A flat spring 11 is secured to the lug 6, its free end being adjacent to one end of the screwthreaded lamp receptacle 12, which is suitably supported on the base 3. The other lamp contact is a spring 13 secured to, said base and rovided with a' binding-screw for the other 'ne-term'inal.
The device for forcing the spring 11 into contact 'with'the rece tacle 12 or with a contact strip 14 secure thereto, and thereby closing the circuit through the lamp, is a tumbler 15 pivoted to'the frame between the-arms of the Y shaped slot 8 and having a lug lowhich bears'jon the spring 11 an a.joint .tacts.
contact with the .stop 7.
An actuator is mounted on the frame and arranged to engage with the cams. It is preferably a plate 19 having near one end a laterally-projecting pivot 20 passing through the stem of the .Y-shaped slot 8 so that the actuator can slide along said slot. At the other end the plate has a laterally-projecting pin 21 extending through sai ot and adapted to engage with.the cams 18. The
of a spring 22 attached to a stud 23 on the frame an a bearing againstthe pivot. In order'to move the actuator, there is provided a rod 24 having a head 25 engaging with a lug 26 on said actuator, preferably by adapted to give freedom ofmovement. A chain or cord 27 is attached to the rod and is let out through a funnel 28 on one side of the shell 1.
. Theoperation is as follows: Suppose the parts to stand as shown in Fig. 1. Then when the chain is pulled, the pin 21 on the actuator will engage the u per cam 18 and ride along until it strikes t e upper hooked arm 17. Continued movement of the ac tuator will rock the tumbler into the posi-. tion shown in Fig. 2, the lug 16 on the tumbler forcing the spring contact 11 down' upon the contact stri' 14. In this position, the parts lock themse ves as the line of pres-- sure of the spring against the lug is radial to the pivot of the tumbler. I The tumbler is prevented from passing this point by a shoulder 29 Whic abuts against the stoplug 7. Whenthe chain is let go, the spring 22 retracts the actuator to the position shown in Fig. 2, with its in 21 in the stem of the Y-shaped slot 8. n this position it is ready, when the chain is agam pulled, to engage the lower cam and hookon the tumbler and return the parts to the position shown in Fig. -1. spring contact assists by its ressure against t e lug 16 so that after a slig t movement of the actuator the spring throws it open quickly, and snaps out'any are at the con The oscillation of the tumblerin that direction is checked by the lug 16 coming in It is .thus ap- 7O actuator is normally held retracted by means In this movement, the
parent that with the mechanism above set forth, one pull on the chain will close the circuit and light the lamp, and the next pull will open the circuit and extinguish the lamp. 5 As the chain can be led to any desired point, the lamp can be readily controlled even if it is located in some high and inaccessible place.
What I claim as new and desire to secure by Letters Patent of the United States, is,
1. In a lamp socket, the combination with a lamp contact, of a spring having circuit connection and arranged to make and break contact with said lamp contact, a tumbler o eratively engaging said s ring, and a v s iding actuator for said tumb er.
2. In a lamp socket, the combination with a lamp contact, of a frame, a flat spring secured to said frame and arranged to make and break contact at one end with said lamp contact, a rocking tumbler pivoted on said frame and operatively engaging said spring, and a reciprocating actuator for rocking said tumbler.
3. In a lam socket, the combination with the screw-shell contact, of a frame, a spring contact secured thereto, a tumbler pivoted on said frame and operating upon said spring to move it into. and out of contact with 'the shell, and an actuator sliding on said frame and engaging with said tumbler.
4. In a lamp socket, the combination with a lamp contact, of a frame, a tumbler piv oted on said frame and having two intersecting cams, an actuatorarranged to engage said cams alternately, and a spring secured to said frame and arranged to make and break contact with said lamp contact and to hold the tumbler in extreme positions.
5. In a lamp socket, the combination-with a frame having a Y-shaped slot, of'a tumbler pivoted between the arms of the Y and hav- 111g two intersecting cams and hooked arms, an actuator sliding in the stem of said slot and adapted to engage said cams, and a said slot and a pin also engaging said slot and adapted to engage said cams, and a spring contact bearing against said lug.
In witness whereof, I have hereunto set.
my hand this 31st day of July, 1905.
JOHN R. BYRNE.
