SOCKET AND ATTACIMENT PLTYJ'G.
To all whom t may concern: 1
Be it known that I, WILLIAM V. D. KELLEY, a citizen of the United States, residin at Brooklyn, in the county of Kings and tate of New York, have invented certain new and useful Improvementsin Socket and Attachment Plugs, of which the followingis a' full,'
clear, and exact specification. Y,
' This invention relates to socket and attachment plugs, and has particular reference to the provision of both a socket and an attachment plug, which can be inserted at one end into an ordinary socket, and having means 4 .at lthe other end for connectlon to lampv or lamp cord. The object of the invention is to combine in both an attachment and a socket plug,
such as an automatic thermostatically actuated controllingswitch for a translating dea lamp. The invention is of general application, although it is intended more especially for the flashing of lam s which are used in connection with advertising devices, etc
.' By this lnventiomtliere is provided within a cylindrlcal casing of about the ordinary diameter of a standard lamp socket, a com.
' plete ashing switch, which only has to be screwed into the socket at one end and connected to a lamp at the other end. to form a liashing unit. `A particular feature of the invention resides in a novel conducting shell,
and the invention further comprises the conj-v struction and 'arrangement of parts whereby the switch can be adjusted while connected j in the light circuit, without either taking the flasher apart, or liability of producing a. short circuit. While flashing devices adapted .for connection at one end with a' lamp socket and at the other end to receive a lamp are known, none of them which have gone A into practical use, so far as I am aware, have been capable of adjustment while in operation, but have had to be disconnected and taken apart for adjustment and then re assembled for trial. In such an arran ment there is no way of telling whether t e ad-` justment is right or not, but by means of v. this invention, the adjustment can be made while the switch is connected in the circuit I and any defect easily corrected. w
.The invention comprises both 'o ia socket plug, which receives `the controlled device d1rectlysucl1 asa lamp', and an attachment plug, which 1s to be connected with the trans`' Specification of Letters Patent.

Fig. 2 shows the porcelain lcontact and switch carrying member in side view;
Fig. 3 is a view of Fig. 2 seen from the "ri ht;
j ig. 4 is a cross-section on the line b-et ofFig.2;-' l y Fig. 5 'is a cross-section of the shell; Fig. 6 shows a cross-section of lan attach-- ment plug;
' Fig. 7 shows an end view with the cap removed, and
n. Fig. 8 shows an elevation partly in section. 1 represents `a socket or outlet having an internally threaded conducting shell 2 connected to one side of the circuit anda center 15 contact 3' connected to the other side of the circult, and of any ordina or standard construction.` .4 represents te switch andl .contact support vof insulating material, such 'as' porcelain, upon which are mounted the thermostatic switch and connected contacts from end to endy forming. one side of'the'circuit. .The support 4 is attachedtoI the shell 5' by screw 15 engaging a nut in slot 35 of support 4. The other side of the circuit is formed by the inclosin shell 5 of'conduct ing material,- and outsl e of'thatis the. ex-
ternal non-conducting insulating ll:shell 6'.
The elongated support 4 is provided with av reduced end 7 which projects through the open end of the shell 5 and is held by the inturned flange 8. Theend 7 carries a contact l whichV is secured to the opposite end of` switch member '13 at 17, and' the members -13 and 16 are also irmly fastened together on the support .by uscrews 18 and nut 19. The switch members 13 and 16 straddle the `tapered stiiening rib 20- on the suport 4, ,as shown iii-Fig. 3,. and spaced rom the bottom of the chamber 21, formed in .the
other end of the support 4. The two members 13 and 16 constitute a thermostatic switch, operating to swing laterally when one leg, as for example 16, is heated or cooled. The heating or cooling is effected by a heating coil 23 which is connected at one end to contact 12, at screw 18, and at the other end is connected across the contact bar 24 which is fastened to the support 4 byyscrew 25. The' contact bar 24 also carriesan adjusting contact screw 26 which is opposite' the hole 27 in the outer non-conducting shell 6 and also the larger hole 28 in the conducting shell 5. The shell 6 thus prevents electrical Contact of the adjusting tool and shell 5. The screw 26 is adjusted toward and from the vibrating contact 29 on the connected ends of the switch members -13 and 16 to vary the period of dashing. As shown herein, the heating coil 23 is in series with the circuit, or across the line, when the contact 29 is separated from contact 26. This causes heater 23 'to heat the 'leg 16 causing it to be elongated and close the circuit at contacts 29 and 26. This shunts the heating coil 23 out of the circuit, allowing the heated leg to cool and open the circuit,l and thereupon the operation is repeated as often as the thermostat heats and cools, depending upon the adjustment of screw 26.
It is of importance to be able to adjust the Contact screw' 26 from the outside while the device is in circuit, which has not been heretofore accomplished in devices of this character. From the contact plate 24, the
.current passes by screw 30 to a center con.
The shell shown in Fig. 5, consists of the socket end having the threads and the inturned end, the intermediate cylindrical portion having the adjusting hole 28, and the outer threaded end for receiving the lamp, or a screw plug.
The combined socket plug and iasher has several advantages, among which are compactness, ease of use, and absence of loose parts. c
In Figs. 6, 7 8, is shown an attachment plug for an extension cord. The attachment end is the same, but instead of the socket 34, means is provided for attaching a cord 38, consistingz of a block 39 interlocking by angular projection 36 with a similar recess in the end 'of body 37, and. fastened to a bar 24 by screw 40 in recess 4l. The body 37 and blo-ch" 39 can. be integral if desired. Also fastened by screw 46 is a wire terminal plate 42 in recess 41 and set screw 43, while 1n recess 44 is the other wire terminal plate 65 45 and set screw 46. 4'? is a contact strip which passes through the block 39 and contacts with shell 5 inside shell 6, as shown in Fig. 7. 49 'is the lamp to be ashed through the cord 38, which passes through a shell 50 and insulating bushing 51, fastened by bayonet slots and screws 52 to nuts 53 in block 39. 54 is an insulating disk within the shell 50. The operation of this form will be similar to that 'heretofore described, and both forms can be adjusted while in operation without liability of short circuiting. The advantages of this form is that an attachment plug and flasher are combined in a unitary article which is already assembled ready for the cord without loose or separable parts which are easily lost or displaced when wanted for use. Various changes and modiications can be made in the details shown herein without departing from the scope of the appended claims.
Having thus described my invention, I declare that what I claim as new and desire to secure by Letters Patent, is
1. A dashing socket plug comprising a tubular conducting shell having one end formed for insertion into an outlet socket to electrically connect said shell and the socket on one side of the circuit, an insulating support within the shell carry7ng a center contact to coperate with a center Contact in the socket for the other side of the circuit, a thermostat mounted at one end on said support and extend-ing longi.
