To atZZ whom it may concern:

Be it known that I, Jenn DUGDILL, electrical engineer, a subject of the King of Great Britain, residing at 305 Oldham road, Failsworth, Manchester, in the county of Lancaster, England, have invented new and useful Improvements in or Relating to Electrical Fittings, of which the following is a specification.

My invention relates to electric fittings; and it consists of the combination of a spring reel or bobbin upon which flexible conductors are coiled and from thence led to a lam or other'current-consuming device, a bal -and-socket joint, and a tube or tubes through which the flexible conductors pass to the lamp. The ball-andsocket joint is located between the housing for the spring-reel and the end of the tube. In some cases the s ring-reel me. be disposed within the be. carried on the end of the tube. B means of the ball-and-socket connection 0 the tube with the housing for the reel the tube can be readily moved and fixedabout a com aratively large area, so that the lamp or otl ier device can be brought to various parts of a work-bench, table, desk, or the like.

The ball-and-socket joint provides universal movement for the tube within suflicient .range for practical utility, the tube being of per tube, the spring-reel aying out the conuctors or taking up the s ack of the same, as

refined.

l 'gure 1 of the drawings shows one form of my invention in sectional elevation. Fig. 2 is a modification in which the tube containing --the flexible conductor is made telescopic.

Fig. 3 1s a cross-section through the line A B, Fig. 2. Fig. 4 shows in section how the ipringqeel may be disposedlwitln'n the ball. a igll 5 shows my invent on a plied to an electro er.

6 indicates ow the fittings may be attached to a wall, and Fig. 7 shows how the fittings may be carried on a table or llo'or.

Referring to 1, within the body or housing 0. 1s mounted in suitable bearings the spring reel or bobbin b. Upon the bobbin 6 are wound the flexible conductors or insulated wires 0, connected to a lamp or other current-consuming device. The reel or bobbin may be a rotary switch constructed in accordance with an invention for which I have applied for Letters Patent, Serial No. 250,226, or it may sim ly be a spring-reel with independent switc 'ng arrangement of any ordinary or suitable construction. I provide the ball-and-socket joint by means of a s here or ball d, secured upon the upper end 0 a tube e, the s herical socket being obtained partly by the ower part a. of the body a and partly by the lower portion f of a surrounding meta ll (1 within the socket sufiiciently to permit the tube 6 being retained in any desired position, the outer casing 9 can be adjusted bymeans of the screws g passing through the flange g and'into the attrass a a space being left between the ange and the pattrass for this purpose. The flexible conductors ass from the spring reel or bobbin 6 throug a conic all bored-out plug 1), of Wood or other suitab e materiel, within the ball (1 and, thence through the tube e, the lower end of which is fitted with a bush e, of ebonite or other insulating substance, which will prevent chafin of the wires as the tube is manipulated an the wires are run up and down the tube. It will be obvious from an inspection of the c casing g. To bind the ball drawings that the tube 6 can be placed and l retained at any angle or direction radiating from the ball-and-socket joint within the limits permitted by the size of the opening f of the socket, so as to bring the lamp over any Ipart of a desk, bench, or the like. The he t of the lamp is re ulated'by either pul ing down the insulated wires 0, thus unwinding them from the reel b,'and coiling up the 5 ring I) in the reel, or by lifting the lamp to re 'eve the Wires 0 of its wei ht when the spring acts to rewind the flexib e conductors upon the reel as will be understood.

In the modification shown in Figs. 2 and 3 two tubes, one telescopin -within the other, are used. Theupper tube It is fluted, the

extreme ed es or peripheries at the upper e upper part of the tube 7c within the tube h, the conductors c shown in the sectional plan yiew, Fig. 3, to permitit to slide within the tube h, but reventing its rotation. The flexible con uctors pass throu h both tubes to the lamp or other device, t e lower end of the tube 70 being connected to suchdevice. To raise and ower the lamp', it sufiices to slidethe being thereby unwound from or rewound upon the reel 6. To prevent the rotation of the upper tUbBJL, whereby the wires 0 might be twisted and strained, a stud n is rovided, passing through a holeo in the soc et f and screwed in the ball (1.

In cases where "the risk of twistin the wires is small the tubes k may be cylin ical instead of being fluted.

The fitting j; throu h which the lower tube passes, ma be in the orm of a packed land. Althoug in the precediii figures have shownthereel mounted wit 'n the body a, in Fig; 4 I show how the reel 1) may be mounted or inclosed within the ball at. The reel in this instance is shown as being a rotary about. their axes except to a limits switch -made in accordance with my said former -patent although any suitable springreel with independent switching mechanism may be used. The bearings for the'reel'are v v provided as shown in the ball d itself, so that 0 the reel pal-takes of the same oscillatory rotated electroliers, as indicated in 5, nor is it limited to lamps'pendent from the ceiling;

but the fittings may be attached to a'wall, as

shown in Fi 6, or carried on a table or floor, as illustrate in Fi :7,

I declare that w at I claim is- 1. In combination in electric fittings, a body or housing, 'atube, a ball connected to one end of the tube, an outer casing, a socket for the ball formed partly in the housing and the outer casing, means for binding the ball inthe socket and compensating for wear, a springractuated reel located above the tube and flexible conductors wound upon the" reel .and passing through the tube to the lamp'or other current-consuming device.

2. In combination in electric fittings a body or housing a, a spring-actuated reel con tained therein, a tube, a ball carried on the end of-such tube, an outer casing'g, a'socket.

for the ball formed partly in the housing a and partly by the casing 9, means for binding the'ballwithin such socket and compen-- sating for wear, flexible conductors wound upon the spring-reel and-passing through the.

tube to the lamp or other current-consuming device, and a bush of insulatingmaterial fitted to the free end of the tubesubstantiallyf as described. p

In testimony-whereof I have signed my name tothi specification in the presence of two subscribing witnesses. r
