To all whom it may cor'zlcei'n:
Be it known that 1, JAMES J. HARTLEY,;8.
' citizen of the United States,residing at Schenoperative in a direction transverse to the axis the base ,so that variations in the length of the base and the relative position of the screw-shell to the switch mechanism will not affect the proper action of the switch.
a part shown broken awa In the accompanying drawings, forming a part of this s eclfication, Figure '1 is a plan of the base an switch mechanism of a socket embodying one form of my invention. Fig. 2is a vertical section of the socket without the inclosing shell, taken on line 22 of Fig. 1; and Fig. 3 is a side elevation of the same with The base 1, which is or porcelain'or other -1noldable'insulating material, is made cylindrical at the lower part and frusto-conical at the upper part. In the upper end of the'base' is formed a central rectangular recess 2 with openings 3 4 leading therefrom at right angles to each other, and in the side of the base oposite to opening 3 is a recess 5, separated om the central recess by a barrier-.6. Adjacent the recess 5 and the opening 3 are formed semicircular grooves'7,and in the lower end of the base are formed a counter sunk screw-hole 8 and a channel 9 with scrgw-holes extending upwardly from each en The switch mechanism consists of a keyshaft 10, provided with side lugs 11 and j our naledin a U-shaped frame 12. At the inner end of the shaft is jour'naled a switch-block 13 with a transverse gain 14, in which the lugs 11 at the inner end of the shaft may move with considerable lost motion before engaging the opposite sides ;of the gain. The U- shaped frame 12 is disposed transversely to the axis of the base 1 and is of a size to Specification of Letters Patent. l Application filed April 27-. 1965. Serial l lo. 257,595.

closely engage three sides of the rectangular recess 2 and is held in place by a screw 1, extending through the base and engaging a threaded lug 16, bent up from the lower edge of-the frame. A bent spring.17 is secured to the side of the frame parallel to the shaft 10 and extends at its free end into bear upon the edge of the switchlock 13 in such-a manner as to normally.,press the latter outwardly in adirection transverse to the axis ofthebase. The bearin in the. frame 12 for the inner end of the sha t is made conosition to siderablylarger than the shaft to ermit of a bodilymovement of that end 0 the shaft withthe .jswitch-block 13. The operating end of the shaftll) extends through opening 4, and in the opening. 3 is arranged a U- shapled contactI1-8, seated in a shallow recess int ebottom ofthe opening and secured in place by a-screw 19.= Theouter endv of the contact 18' is provided with a binding-screw 20, and the inner end lies between the walls of the .openin 3 inposition to be engaged by In the recess 5 is secured the'center contactmember 21, consisting ofa strip of sprin metal .bent to the desired shapefprovide with a binding-screw 22 and held in'place by a screw 23.
construction and is held in place on the upper end of the base by two screws 25, which extend through the base when one is enga ed by a nut while the other is engaged by a. at metal strip 26, lying in the channel9, which extends lengthwise thereof and engages at its opposite end I with screw 15, whereby the switch-frame 12 is electrically connected to the screw-shell 24-. r
1. In a lamp-socket, the combination of a one-piece base, a screw-shell contact mount- I do not desire to restrict myself to the parclaim as new, and desire to secure ed upon one end of said base, a switch mem- Y her, a U-shaped switch frame mounted'on said base transversely to its axisvand electrically connected to said shell, and a stationary contact secured to said base in position to be engaged by said switch member.
2. In a lamp-socket,lthe combination of a one-piece base provided with a central rectangular-recess having openings from two sides thereof, a switch member having its shaft extending through one of said openings into said 'recess,-a U-shapcd switch-frame secured in said recess transversely to the axis of the base, and a stationary contact arranged in the other openingin position to be engaged by said switch member.
3. In a lamp-socket, thecombination of a one-piece base having a side recess and a rectangular center recess separated from the side recess and connected to twov side openings at right angles to each 'other, a screwshell contact secured to the upper end of said base, a center contact secured in the side re'-. cess, a switch member having its shaft arranged in one of said openings, a U-shaped switch-frame disposed at right angles to the axis of said base and electrically connected to through one of said openings, a U-shaped frame arranged in said recess in engagement with the walls on three sides thereof and provided with a contact-spring normally acting to force the switch transversely to the axis of the base, and a stationary contact arranged 'in the other opening in position to be engaged by said switch member.
