SOCKET-SUPPORT FOR ELECTRIC LAMPS.
Specification of Letters Patent.
Patented Aug. 9, 1910.
Application filed March 5, 1910. Serial No. 54?,501.
To all whom it may concern:
Be it known that I, l VILLIAM O. Tnnoon mo, citizen of the United States, residing at substantially as shown and described and respectively, all of which aroshown sepparticularly pointed out in the claims.
In the accompanying drawings, Figure l' is a side elevation of my improved socket, and Fig. 2 is a corresponding elevation a quarter turn farther around. Fig. 8 is a rear or inner end elevation. Fig. at is a longitudinal sectional elevation at Fig. l, and Fig. 5 is a longitudinal sectional clevation of 'Fig. ldig. 6 is a central sectional. elevation or the body member on line w-w,
1, and Figs. 7, 8 and 9 are corresponding elevations of the supporting plate for the sot'eket, the cap or ring and the thimblc arnted in these vicwsliiutassembled in ili s.
"-1, 2, t and 5. Fig. 10 is an inside or bottom view of the body of the socket looking into its open end.
'ihe device as thus shown comprises three main parts, a body or inner member B, a ring shaped cap or outer member C and a thimble or shell D. The said body and ring or cap are usually made of porcelain but maybe of any equivalent;- materlal, and thimhle ll) is of a good conducting metal,
of c ppcr.
E represents a sign plate, assuming that the sockets are used in sign display work, and that said plate serves as a support for the sockets as shown herein.
llow, as to the details of said several parts, it will be seen that in the main said details are'original and peculiar to this particular socket and that they promote simplicity of construction. and case and convenience in asscmldingor in replacing parts and in making needed repairs, as the case may be. Thus, the body of base member 13 has opposite ribs or enlargements 2 lengthwise which abut againstthe plate it while the entire innnediate edge 3 of said, body projects through a perforation or opening 6 in said plate, and ring or cap C has an annular rccess i in its side adapted to engage over said edge 3 upon the opposite or front side of plate E, as seen in Figs, 4 and 5 and where the edge of said body projects through said plate for this purpose. As to this feature of the invention it may be further observed that the'socket as a Whole is supported on or in plate E through the said parts B and O and the flaring mouth 5 of thimble D engaging in the flaring seat in ring C, and the screw F which connects the said parts and is provided with a nut seated in a recess in the bottom (rt-body B. Specifically the head of screw 1* is engaged in. a metallic Washer (3 in the bottom of thiinble D and which is separated from said bottom by aninsulating sheet T, and an electrical. spring contact lip 8 on washer l overhangs the head of said screw and adapted to provide one termii'ntl contact when lamp is screwed into the socket. .llurlhcr, the said body B contacts with plate 1) only at the ends of ribs 2 and not otherwise, and said ribs have indentations 5) adapted to seat on the short strlmk-up ribs ll) in plate l) which serve to [ix the socket against rotation on its seat when fastened in place. At the othor'or outer end of the body the said ribs lorm lateral outer walls to recesses ext ending across the body at that point and which are adapted to receive the binding screws 12 and '13 respcctivcly. These screws are practically buried in said recesses, or may be covered. with an insulating wax or cement, il' preferred, and as is shown as to the outer oxtremity of screw or bolt l1, vl igs. 4- and 5. Connection is made by metallic strip or piece l-flbetween screw 13 and bolt 1*, and by washer 15 and screw 16 between screw 1.2 and contact segment 18, llig. 10. ,Said segment .or piece lies fixed in the bottom of body l and has its ends (3 turned up in swing relation. against the side of the socket and in position to make double contact oppositely with lhimblc .l), which, however,
- and pretcrablv does not contact at its bottom with said segment .18 when drawn to its seat at llnring edge 5 by locking bolt lfl but only contacts at or with upturned ends 0 of the said segn'ient. Electrical connection is then made with the lamp to .be inserted by i means of the thimble at one side and through the said spring lip 8 at the other side. To separate the parts it is only necessary to remove screw F and then all the parts will be subject to separation as seen in Figs. 6 to 9, and'they are assembled with equalease and facility.
It will be seen that shell or thimble D is threaded to screw a lamp thereinto as usual, but said thread has no other use, and the ring C is engaged and held in working position exclusively by. means of the flare 5 of said thimble.
Now, as .to other features it is well known that usually the diaphragm or bottom portion of socket member B is rather frail and liable to be cracked or broken in clamping the parts together, andto avoid this weakness and danger I have strengthened said portion with a rib b and bent the terminal strip or piece 14 to conform to said bend and hook over or upon the same, and thus it follows that strain delivered through clamping screw 16 which otherwise would come on said diaphragm is in fact largely transferred to the end of said terminal 14, and which does not ordinarily contact with said diaphragm or bottom portion. It will also be observed that the body proper of member-B has the same size in cross section as the hole or opening in plate E for the socket, and that ribs 2 constitute the sole stops to prevent projecting said body through the plate. The proportions of the body proper and said ribs and their disposition relatively are clearly seen in. Figs. 1 and 3, and wherein it is seen that said ribs extend outward be yond said body. proper proportionally about as shown. The transverse grooves or channels 11 in which the binding screws 12 and 13 are located are behind the ends of the said ribs looking from the outside. Again, the said segment or equivalent part 18 in the bottom of body B is especially material as herein shown because the end extensions .0
thereof have sufficient length to make a good contact with shell or thimble I) even E plate E be unusually thick or heavy, and screw 1* has suiiicient length to accommodate itself to such possible diii'erences. This would also operate to make a difference in the depth to ble seated therein having a flaring mouth fitting in a corresponding flare in said outer member and means to lock all said parts together.
2. lamp socket having a body proirided with side ribs, a plate having a hole through which said body projects and against which I said ribs abut, an inner member having "anannularrecess suited to the corresponding edge of said body and flared at 1ts outer edge, and a socket thimble having a flaringv edge corresponding to the'flared edge of the said inner member. 4
3. An electrical socket having a conduct-- ing piece laid in said socket having its ends bent at substantially right angles and resting next to the side wall of the. socket, and a metallic thimble in adjustable contact with said members.
4. A two-part electrical socket, a conducting piece in the bottom thereof having extensions next to the wall of the socket and a conducting thimble in engagement with said extensions at varying depths, and. a clamptween said cavity and groove, an electric.
terminal engaged in both said'groove and screw connection between said thimble and the end of said terminal in said cavity.
.said cavity and bent to substantially U shape over said rib, a thimble insaid socket and a I 6. In an electrical socket, two separable body members, in combination with a conducting shell and a screw to clamp said members upon plates of diflerent thicknesses, and an electrical contact mounted upon one.
of said members in slidable contact relation.
with said shell.
7. In an electrical socket, two separable body members and a eonductin shell, one of said members having a per orated diaphragm and a terminal member mounted at the rear thereof and apart from said diaphragm, and a screw between said shell and terminal member to draw said body members together upon said diaphragm.
8. In an electrical socket, two separable body members and means to clam members upon a plate comprising a anged' conducting shell and a screw, and said shell having slidable interlocking engagement with one of said members adapting longisaid a tudinal movement in respect thereto and preventing independent rotation of said she 9.

10. In an electrical socket, a plate having an opening therein and raised portions thereon at the edges of said 0 ening, in combinafltion with two separab e socket members adapted .tobe clamped upon opposite sides of said plate and a conductix lg shell mounted in one of said members and having a flaring mouthengaged .in' the other member, and one of said members having indentations to seat said raisedportions of said plate to fix Wi'txies s:
