JOHN H. DALE, OF NEW YORK, N. Y.

SHADE-HOLDER.

To all whom it may concern:

Be it known that I, JOHN H. DALE, a citizen of the United States, residing. at the city of New York, in the borough of Manhattan and State of New York, have in vented certain new and useful Improvements in Shade-Holders, of which the following is a full, clear, and exact description.

My invention relates to a form of shade holder or support particularly for use with electric fixtures. The ordinary holder for this purpose makes use of a sheet metal frame with clamping screws which have to be tightened upon the shade at a number of points thereabout. This manipulation is troublesome, and furthermore objectionable as the nature of the support is absolutely unyielding to accommodate any expansion and contraction of the shade.

It is one purpose of my invention to provide a shade holder which clasps into firm engagement with the shade by a single movement or operation, but which holds with great security in use. I also provide a fastening which accommodates any expansion or contraction which may take place in the material of the shade. I further provide for the convenient attachment of the shade holder to the usual lamp socket of the type ordinarily employed and either screwed to a wall bracket or depending from a flexible cord connection. Lamp sockets of this class ordinarily have a circumferential groove in which a part of the holder is engaged by a clamping screw. This is obviously expensive and troublesome. I make use of a spring means for this purpose, in combination with the spring clasp which holds the shade. In one form of the present invention I make use of the same springs for holding the shade and engaging the socket.

\Vith these various and other objects in view, my invention consists in the features of construction and combination as hereinafter set forth and claimed.

In the drawings: Figure 1 is a side view of a shade holder embodying the principles of my invention in use with an ordinary switch socket and shade. Fig. 9. is a vertical sectional view of the same. Fig. 3 is a bot tom plan view of the holder. Fig. 4 is a vertical sectional view of a slightly modified form of the invention.

Referring'to the drawings, in which like parts are designated by the same reference Specification of Letters Patent.

Application filed July 3, 1908.

Serial No. Ml/74:2.

sign, 1 indicates a shade holder conveniently made of sheet metal, spun into a somewhat conical or flaring outline as shown in Fig. 2, and open at its ends 2 and 3 to receive the lamp socket and the shade respectively. The form of the shade holder may be of any ornamental character desired, but I prefer that shown, having a central zone a with perforations for the escape of hot air, and having beads forming internal annular grooves 5 and 6 at the portions immediately adjacent to the respective openings 2 and 3. S designates a ledge which may be formed in a plane transverse to the axis of the device. This ledge forms a stiff support for the springs which I employ for holding the shade, and in some instances, the lamp socket as well.

In Figs. 2 and 3 I have illustrated three spring blades 9 fastened to the ledge 8 at equally spaced-apart points on its interior under face in any convenient way, as by means of screws or rivets 10. These springs depend downward in a form or outline generally corresponding to that of the holder, but out of contact with its interior surface, so as to permit an outward yielding movement. At their lower ends, these springs are rounded inward to provide protuberances 11 adapted to engage the usual groove or rim at the top of an ordinary shade. The protuberances 11 are so formed on the springs that they lie opposite the groove 6 of the holder, into which they are capable of yielding outwardly when the device is being at taehed to the shade.

In the form of the invention shown in Figs. 1, 2, and 3 the spring blades 9 are continued upward as well as downward from their supporting rivets 10, forming prongs 12 with inwardly directed protruding portions or projections 13. The form of the upward extensions or prongs 12 is most conveniently made a reverse curve at their extremities corresponding roughly to the out line of the head 5 situated immediately outside the same and adapted to cooperate with the usual bead l-ilof the switch socket. These prongs are normally separated a slight distance from the surrounding wall of the holder so as to be capable of yielding outwardl y when engaging the lamp socket.

The use and operation of the holder will be clear from the foregoing description. It is merely necessary to snap the prongs 12 over the usual head of the socket and sumlarly engage the prongs 11 over a shade of the ordinary character, whereupon the parts are all firmly assembled together for use. The character of the engagement is sufficiently secure for all purposes and permits relative expansion and contraction of the parts. At the same time. the parts may be quickly disengaged and separated whenever desired.

In Fig. 4 I have illustrated a slightly modified form of the invention in which the spring blades 9 extend only downward from their supporting rivets, separate spring means being provided for engaging the switch socket. A convenient spring means for this purpose is that which I have fully set forth iii my Patent No. 803,883, issued Nov. 7 1905, and including a spiral spring 15 which surrounds a metallic ring 16 within the upper groove 5 of the shade holder. This device is capable of establishing a firm connection with the usual bead of the socket when pressed thereon, in an obvious way.

lVhat I claim is:

1. A shade holder comprising a sheet metal casing having a continuous unbroken lower edge and having a plurality of spring blades depending therein and adapted to engage a shade, said blades being concealed and limited in their outward movement by said casing.

2. A shade holder comprising a casing having a bead at its lower side and a plurality of spring blades Within said casing having bent portions within said bead adapted to engage a shade, whereby said spring blades are yieldable outwardly with their bent portions entering said bead.

3. A shade holder having spring blades fastened at points intermediate their length within the shade holder, said springs having inwardly directed protuberances at their upper and lower extremities to engage a lamp socket and shade respectively.

In witness whereof, I subscribe my signature, in the presence of two witnesses.

JOHN H. DALE.
