UNITED STATES RICHARD H- CBONINGER, OF DAYTON, OHIO.
LAMP SOCKET.
Application filed March 22, 1920. Serial No. 367,588.
To all whom it may concern:
Be it known that I, RICHARD H. CnoN- INGER, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Lamp Sockets, of which the .following is a. specification, reference being had therein to the accompanying drawing.
This invention relates to lamp sockets and more particularly to a lamp socket of the bayonet slot t pe.
One object of the invention is to provide a lamp socket of porcelain, or other insulating material, which will be simple in construction, easy to assemble, and of a strong, durable character; and further to provide such a socket adapted to receive "a lamp base of the bayonet, or Ediswan, type.
A further object of the invention is to provide a device of this character, the essential features of which may be embodied in both a cleat base socket and an adapter.
Other objects of the invention will appear as the device is described in detail.
In the accompanying drawings, Fig. 1 is a side elevation of a double contact cleat base socket embodying my invention; Fig. 2 is a sectional view taken centrally through the socket of Fig. 1; Fig. 3 is a plan view ofthe socket of Fig. 1; Fig. 4 is a plan View of a socket similar to the socket of Figs. 1 to 3 but having a single contact member; Fig. 5 is a side elevation of a double contact adapter Fig. 6 is a vertical section taken through the adapter of Fig. 5; Fig. 7 is a sectional view showing the two parts of the adapter separated; Fig. 8 is a plan view of the adapter of Figs. 5 and 6; Fig. 9 is a plan view of the socket portion of the adapter; Fig. 10 is a plan view of a single contact adapter; and Fig. 11 is a vertical wctional view taken centrally through a single contact adapter.
In these drawings I have shown both a cleat base socket and an adapter embodying the essential features of my invention. The cleat base socket of Figs. 1 to 4; comprises a body 1 of porcelain, or other suitable insulating material, comprising a base portion 2 and a socket portion 3 formed integral with the base portion. The base is provided with openings a to receive screws, or other suitable attaching devices, and the socket portion 3 is provided with the usual shell. or lining 5 of metal, which is preferably provided with a pair of bayonet slots -6 to adapt it to receive a lamp base of the bayonet type, commonly known commercially as the Ediswan base. The innerend, or bottom, of the socket portion 3 is formed by the adjacent portion of the base 2, which, as has been stated, is formed integral therewith, and it is provided in its opposite sides with openings or slots 7 which, in the form. here shown, extend lengthwise of the body, the side walls of the base being cut away, as shown at 8, to form channels into which the slots open. Arranged within the socket portion 3 are suitable contact members, which are connected, by suitable conductors extending through the slots 7, with terminals 9 arranged on the exterior of the body 1, and in the present instance mounted on the base 2 at the bottoms of the grooves, or channels, 8. In the case of the double contact socket of Figs. 2 and 3, the contact members comprise contact fingers, one of. which, the contact 10, is secured to the bottom of the socket by means of a bolt 11 extendin through the base 2. This contact mei'n r has secured thereto and preferably formed integral therewith, a bar of metal 12 which extends through one of the slots 7 and is connected with the terminal 9 at the bottomof the adjacent channel 8, preferably by providin the same with an aperture through whic the bolt forming part of the terminal extends. The other contact finger 13 has an end portion 14: extending into the other slot 7 and clamped in firm engagement with a bar of metal 15 which is secured to and forms part of the shell 5 and which extends through the adjacent slot 7 and is connected with the second terminal 9 in the same manner that the bar 12 of the first contact finger is connected with the first terminal. As will be apparent the construction is very simple, and in assembling the socket structure the shell is placed in position, by threading the bar 15 through one of theslots 7 and attaching the same to the belt of one of the terminals 9. After the shell is placed in position the end portion 14 of the contact member 13 is inserted in the slot and is drawn tightl into place by the bar 15 as the latter is tig toned down. Thus the bar 15 serves both to firmly secure the shell 5 within the socket 3 and to establish an electrical connection between the contact finger and the terminal. The other contact member, 10,
is then placed in position, its conductor bar. 12 being passed through the opening 7 and attached to the corresponding terminal 9. The bolt 11 is then placed in position to attach this second terminal to the bottom of the socket. The whole assembling operation is very quickly and very easily performed and the resulting structure is of a very strong, durable character and the terminals are so arranged that they are readily accessible for connecting the wires therewith.
In the case of the single contact socket of Fig. 4, a single contact finger 16 is employed and is similar both in construction and in the manner of mounting, to the contact finger 10 of the Figs. 2 and 3, with the exception that the finger itself is so shaped that the contact portion thereof is arranged centrally of the socket. in this socket is had through the shell 5 and through the bar 15 by means of which that shell is connected with the second terminal. In all other respects the construction of the single contact cleat base socket is similar to the construction of the double contact cleat base socket.
Many of the same features of construction are embodied in the adapter. As shown in Figs. 5 to 11 the adapter consists of a body 17 comprising a base portion 18 and a socket portion 19 which is formed separate from the base portion and which is rigidly secured thereto by means of a bolt 20 extending through alined openings in the bottom of the socket 19 and in the base 18. The bottom of the socket portion 19 is closed by a part 21 formed integral therewith and slots 22 are formed on the opposite sides of the socket between the bottom portion 21 and the side walls thereof. A shell 23 is mounted within the socket portion 19 and has a bayonet slot 24 to adapt it to receive the ba onet lamp base. The shell is secured in position by means of strips or bars 25, secured to the lower edges of the shell and preferably formed integral therewith, which extend through the slots 22 and have their outer end portions clamped between the two parts of the body. As inthe case of the cleat base socket, one, or both, of the bars 25 preferably constitutes a conductor by means of which one of the contact surfaces within the socket is connected with the exterior terminal. In the case of the adapter one of the terminals comprises a screw threaded exterior shell 26 b means of which the adapter is screw threa ed into the sup porting structure, or socket. The outer end of one, or both, of the bars 25 is in contact with this outer shell 26 and is preferably soldered thereto, as shown at 27. In the case of the single contact adapter of Fig. 11 the inner shell 23 constitutes one of the contact surfaces and is thus directly connected The other contact.
with the exterior terminal. The other contact is in the form of a resilient finger 28 which is secured in position centrally to the bottom 21 of the socket by means of the bolt 20 which connects together the two parts of the adapter and which also constitutes the second exterior terminal of the adapter. In the case of the double contact adapter of Figs. 6 and 8, the one contact finger 29 is mounted in the same manner as is the contact finger 28 of the single contact adapter but is so shaped that the end portion, or contact surface thereof lies at one side of the socket instead of centrally thereof. The second contact member is also in the form of a finger 30, the end of which is arranged at that side of the socket opposite the finger 29 and this second finger 30 has secured thereto an extension or bar 31 which passes through one of the slots 22 and is clamped in engagement with the bar 25 of the shell and is connected by this bar with the exterior shell or terminal 26. It will be noted that this construction is also exceedingly simple and is of such a character that the adapter can be very readily assembled. To assemble the same the shell 25 is first inserted in the socket portion 14: of the adapter and the bars 25 thereof passed through the slots 22 and bend outwardly. The base 18 is then applied to the socket, the finger 29 placed in position and the .bolt 20 inserted through the contact finger and the two parts of the adapter body and tightened down to secure these parts in position. The outer ends of the bars 25 are then soldered to the exterior shell 26 and the ends of these bars serve both to establish electrical contact with the exterior shell and to. secure that shell in position on the cylin drical wall of the adapter.
While I have shown and described certain embodiments of my invention I wish it tobe understood that I do not desire to be limited to the terms thereof as various modifications may occur to a person skilled in the art.
Having now fully described my invention what I claim as new and desire to secure by Letters Patent, is:
