STANDABD FOR ELECTRIC LAMPS.

Specification of Letters Patent.

Application filed June 22, 1914. Serial No. 846,435.

To all whom it may concern Be it known that I, IVALTER :0. Hour, citizen of the United States, and resident of the city of Providence, in the county of Providence and State of Rhode Island,have invented certain new and useful Improvements in Standards for Electric Lamps, of which the following is a specification.

This invention relates to a portable, collapsible standard for electric lamps and the like, and has for its object to provide such a standard constructed of a plurality of interlocking standard members which are readily assembled and connected together to form a firm and rigid standard of attractive appearance and also one that is readily separated, taken apart or knocked down to facilitate shipping.

IVhile this standard may be used for any purpose for which it is adapted, yet the same is more particularly designed for use as a support for an electric lamp, on the pointed end of which is rotatably mounted an inverted cup shaped shade or screen, the skirt of which extends down over the l1ght and a portion of the-standard, a'nd s for the purpose of carrying advertislng or other display matter on its surface, the whole screen being adapted to be rotated by the action of the heat generated by the lighted lamp within With these and other objects 1n wow, the invention consists of certain novel features of construction, as will be m0re fully described and particularly pointed out 1n the appended claims:

In the accompanying drawlngs: Figure 1 is a side elevation of my improved standard with a socket and an electric lamp supported therein. Fig. 2- is a detail of one of the standard members. Fig. 3:- 1s a section on line 3-3 of Fig. 1 showing the intersection of the two standard members,

and the angular arrangement of their lower portions to form thebase. Flg. 4 1s a section on line 4-4 of Fig 1 through the lamp socket.

Referring to the drawing 10 and 11 designate two different standard members, each of which is formedfrom thin or sheet material preferably from cardboard or the like. Each standard member has a laterally ex tending base portion in the form of legs or feet 12 and 13, and the body portion of each is elongated to permit the skirts of the lan-.

tern or screen to extend down thereover, the same being nicely curved to present a handsome and attractive standard of strong construction when the members are locked together. Each of these standards is provided with upwardly extending projections or tenents 14, which are adapted to engage corresponding recesses 15 in a binding collar 16. This collar may also be made of any thin or suitable material but it is preferably made of the same material as that of the standard. The middle portion 17 of this collar is cut out forming a central aperture for the reception of the lamp socket- 18, and I have preferably formed a plurality of lips 19 extending inwardly from the stock about the edge of this aperture, the lips being preferably resilient, springy or yieldable to facilitate the passing of the lamp socket therethrough and to engage and yieldably support the upper portion of the socket when positioned therein.

In order to provide a second or lower support for the socket, I have cut out the middle portion of the standard from its upper end downward as at 20, and have formed inwardly extending shoulders 21 on the inner edge of this standard against which shoulders the lower portion 22- of the -socket rests. Another aperture or cutout portion 23 is formed below these shoulders 21 for the purpose of permitting the cable or electric light wires 24 to extend outward from the bottom of the socket.

In order to provide simple and effective means for assembling and connecting together the two standard members 10 and 11 I have formed a central longitudinally disposed narrow slot 25 in line with the axis of the standard, the width of which is substantially the thickness of the opposite member; The slot in one member extends downward from the cut out portion 23 for a given distance and the slot of the opposite memberextendsupward as illustrated in dotted lines at 26 in Fig. 2 to meet the said opposite slot whereby when these two members are placed across each other, see Fig. 3, the slots at their intersecting por-' tions register and permit the members to be passed into position and to interlock one- I with the other. 4

It is found in practice that these standard members should be firmly tied together in order to stiffen thewhole and retain these Patented Nov. 24;, 1914:.

members in proper relation one with the other. In order to accomplish this in a simple and effective manner I have formed tenents or projecting portions on the upper ends of each standard member, which tenents are engaged by the locking collar 16 above described to rigidly tie the whole together.

By my improved construction it will be seen that the weight of the lamp and the screen or shade supported therefrom is all carried directly on the central vertical axis of the standard, thereby reducing to a minimum the liability of tipping over.

My improved standard is particularly de signed to support the shade or rotatable screen 27 mounted to rotate on the glass point 28 of the electric light bulb 30. This lantern is provided with suitable radial openings through its top (not shown) having portions 31 bent either up or down out of the plane thereof, forming blades whereby the action of the heat generated by the light in the rising through said openings cause the screen torotate and so provide means for automatically revolving and displaying the matter on its translucent skirt.

Another essential feature of my improved invention is the fact that the parts of the standard may be readily assembled and set up in correct working shape in a few seconds, and may be as readily taken apart and the different sections removed, which will permit it to lie perfectly flat to greatly fa cilitate shipment.

In the drawings and specifications I have shown and described two standard members arranged to intersect each other and be connected together, but I do not wish to be limited to the use of two members only as any desired number of members may be employed in the construction of the standard. Neither do I wish to be limited to a collar shaped tying member engaging the upper ends of the standard members, as any desired means for tying the member rigidly together maybe employed withou departing from the spirit and scope of my invention.

I claim:

1. A portable, collapsible standard for electric lamp sockets comprising a plurality 1.1 aaaoa of intersecting, interlocking standard members each having a supporting base portion, means for firmly tying said members together and means in said members for receiving and supporting a lamp socket.

2. A portable, collapsible standard for electric lamp sockets comprising a plurality of intersecting, interlocking standard members each having a supporting base portion, a collar for supporting and tying together the upper ends of said members, and means in said collar for receiving and supporting a lamp socket.

3. A portable, collapsible standard. for electric lamp sockets comprising a plurality of intersecting, interlocking standard members each having a supporting base portion, a member for supporting and tying together the upper ends of said standard and inwardly extending resilient lips on said memher for receiving and yieldably supporting a lamp socket.

4- A portable, collapsible standard for electric lamp sockets comprising a plurality of standard members arranged to cross and interlock with each other, the lower ends of said members coiiperating to form a broad angular supporting base, and a slotted collar engaging tenents on their upper ends to support and firmly tie said ends together said collar being provided with a central opening having inwardly turned resilient lips to receive and support a lamp socket.

5. A portable, collapsible standard :li'or electric lamp sockets comprising a plurality of thin standard members arranged to cross each other, each member being provided with one or more slots to receive a corresponding portion of the opposite member, the lower ends of said members forming an angular base, a member for tying the upper ends of said standard together, means 1n said member providing an upper support for a lamp socket and the inner edges of said standard members being formed to provide a lower support for said socket.

In testimony whereof I aifix my signature in presence of two witnesses.
