HENRY .DOLIER, Jlt, OF PHlLADELPHIIA, PENNSYLVriNlA.

Ll illit'll Sl-lMUlE SPECIFICATION forming part of Letters Patent No. 783,?ei l, dated February 28, 1905.

Application filed May 10,

To (1 whom it may concern/.-

Be it known that I, H nNuY l )()nmn, .n-., a citizen of the United States, residing at lhila' delphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and usefulLamp-Shade Attachment, of which the following is a specification.

My invention relates to means for attaching or applying a reflector or shade to a lamp or lamp-fixture, more especially to an incandescent-lamp socket.

My invention consists of a lamplixture shell or casing in which the attachment portion of the shade or reflector engages in a mannor to permit the rotation of the shade or reflector with respect to the shell or casing.

.It is the object of my invention to provide a shade and attachment which will permit the rotation of the reflector or shade about the lamp, so as to direct the light to any desired region,more especially in the case of an incandescent electric lamp mounted with its axis approximately horizontal, though it should be understood that the herein-described shade attachment may be employed in any other relation.

Reference is to be had to the accompanying drawings, in which--- Figure l'is a side view, partly in section and partly in elevation, illustrating my invention. Fig. 2 is an end elevational view of the refiector. Fig. 3 is a side clevational view of the reflector.

Referring to Fig. 1, L represents an ordinary incandescent lamp having lilan'ient a, the axis of the lamp being approximately horizontal in order that the maximumillumination may be obtained in a vertical direction. The lamp as shown has an Edison base, the screwthreads engaging in the screw-thrcaded shell member Z) of the socket, while the central button-contact engages with the contact j" of the socket. This lamp-socket is mounted upon a porcelain member inclosed within a casing composed of the two portions (1 and l), preterably of sheet metal.

l is an attachment-plug whose button-contact is represented at (Z and whose screwthreaded shell-contact is re n'esentcd at ltxtending axially through the attaizhment-plug 190 Serial No. 207,212.

1 is the screw s, whose head contacts with and rotates in the mitten-contact (I. The screw s is rigidly secured to the porcelain member within the casing formed by the members (l and l).

11 is a piece of insulating material in which the screw s engages. Secured to this piece i is the shell member I), held by the screw 1:. The porcelain member within the casing rotates with respect to the attachment-plug .l, and means are provided for maintaining electrical communication between the contacts of the attachment-plug and the lamp-socket contacts B and f in a manner and For a purpose similar to that disclosed in my ap'pl' jzation liled March at, 1904;, and bearing Serialllo. 196,583.

c is a bushing of insulating material immediately surrounding the lamp-socket contact The mijmibers C and ll have :ylindrical poi tions H, a hall being on each member. l lach oi these cylindrical portions has a bead B, the beads on the two members C and I.) registering with each other to form a continuous head or channel within the cylindriczitl portions.

1% represents a shade or reflector, preterably struck out oi? sheet metal and having its edge curled at l. to stifl'en it. This reflector corresponds in shape with the outline of the lamp-globe and terminates at its smaller end in a ring member (i, of the same piece with the body portion of the reflector. This ring portion G is complete except for the gap 1*.

It is a bead extending around the ring member Ur and is of such dimensirms as to engage within the bead B on the socket-casing me1nher, the ring portion (i registering within the cylindrical portion ll of the casing member. The gap 1* renders the ring member (ii in the nature oi a resilient ring which may then expand to snugly engage within the cylindrical portion lll. By this means the reflector member R is supported by the casing member and is rotatable about the lamp L, because the ring member (-2 is rotatable within the cylimlrical portion ll.

The ring portion (i is placed in proper position within one halt of the cylindrical portion I [---that portion 011C, for example. 'lhen the membm' ll is brought into proper relation with respect to (l, the cylindrical portion ll on member D then closing around the remaini bead on said ring member, a socket-casmgming portion of the ring member G, or with the gap F sufliciently great the ring member G may be compressed by the hand to smaller diameter until the bead E is able to pass into the cylindrical portion H, the members C and g D being secured together in normal position. Then the ring member G will expand and iill out the cylindrical portion H, when the bead E will register with the bead B.

As a counterweight corresponding with the counterweight of my aforementioned application the member IV is employed, said member having a ring portion with a bead similar to G and E and engaging in the bead B in a cylindrical portion H on the left of Fig. 1.

The member IV serves as a pedestal whereby the lamp may stand upon end and be moved about from place to place as a portable lamp.

Though I have shown the ring member (Jr as integral with the body portion R of the reflector or shade member, it is to be understood that such ring member may be made independently of the body portion R and secured thereto by riveting, soldering, or the like.

What I claim is 1. In combination, a shade comprising a body portion and a ring member, a socketcasing comprisinga plurality of members secured together, each of said members engaging said ring member.

2. In combination, a shade comprising a body portion and an incomplete ring member, a socket-casing comprising a plurality of members secured together, and means on said members for engaging said incomplete ring member.

3. In combination, a shade comprising a body portion and a beaded ring member, and a socket-casing comprising a plurality of members secured together, said members engaging said beaded ring member.

4c. In combination, a shade comprising a body portion and a resilient ring member, a socket-casing, and means thereon for embracing said ring member. whereby said shade may rotate with respect to said socket-casing.

5. In combination, a shade comprising a body portion and a beaded incomplete ring member, a socket-casing comprising a plurality of members secured together, and a beaded portion on each member, said beaded portions embracing said beaded ring member, whereby said shade may rotate with respect to said socket-casing.

6. In combination, a shade comprising a body portion and a ring member secured thereto, a bead on said ring member, a socl et-casing, a bead on said socket-casing, said beads registering with each other, whereby said shade may rotate with respect to said socketcasing.

body portion and an incomplete ring member,

a bead on said ring member, a socket-casing, a bead on said socket-casing, said beads registering with each other, whereby said shade is supported by and may rotate with respect to said socket-casing.
