COMBINED ELECTRIC-LAMP SOCKET-HOLDING SHELL AN'D SHADE-HOLDER.

Specification of Letters Patent.

Patented July 6, 1915.

Application filed August 27, 1913. Serial No. 786,868.

To all whom it may concern Be it known that I, HARRY W. LAWRENCE, a citizen of the United States of America, residing in the city and county of Denver and State of Colorado, have invented a new and useful Combined Electric-Lamp Socket- Holding Shell and Shade-Holder, of which the following is a specification.

My invention relates to a new article of manufacture, and consists of a combined square shaped electric-lamp socket-holding shell, and a shade holder, and a square shaped connecting device for connecting them together; and the objects of my invention are: first, to provide a socket holding shell and a shade holder, and means for connecting them together, in which the shade holder is detachably secured to the socket holding shell; and second, to provide a combined socket holding shell and shade holder, in which the parts are made independently of each other, and are detachably connected together bya square shaped connecting and locking mechanism. '1 attain these objects by the mechanism illustrated in the accompanying drawings, in which:

Figure 1, is a side elevation of a combined socket-shell and shade holder embodying my invention. Fig. 2, is a central sectional elevation of Fig. 1. Fig. 3, is a plan view of the shade holder by itself. Fig. 4, is a side elevation of the shade holder. Fig. 5, is a fragmentary side elevation of the end of the socket-shell. Fig. 6 is a sectional plan view of the clamping ring. Fig. 7, shows a fragmentary view of the shade holder showing the preferred arrangement of connecting the ends of the piece of metal from which the shade holder is stamped, together. Fig. 8, is a side elevation of a plane form of socket shell. And Fig. 9, is a sectional view of the clamping ring shown in Fig. 6.

Similar letters of reference refer to similar parts throughout the several views.

Referring to the drawings, the numeral 1 designates the socket holding shell portion of my invention; and 2 designates the shade holder portion of my invention. This socket holding shell and also the shade holder are made of square or cubic form of shape and outline, as this square or cubic form of construction constitutes the preferred and an essential feature of my new article of manufacture. My invention, however, is not limited to particular designs of these square or cubic forms illustrated, as my invention contemplates any and all square or cubic shaped 7 socket holding shells and shade holders that are arranged and adapted to be attachably connected together into a combined, unitary square or cubic socket holding shell and shade holder. Consequently the socket shell as long as it is of a square form, may be perfectly plain as shown in Fig. 8, or be embellished by bands, annulets, molding, or other characters of embellishments, it, being only essential that it be provided at one end with a removable cap portion 3, which is made to fit closely over its upper end 4: to fasten thereto by tongue portions 5, formed on two of its opposite sides on its body portion, and apertures 6 formed in two of the opposite sides of the cap portion and arranged to spring down over said tongue portions so as to lock or catch on the same, or bv any other suitable means. The top of this cap is provided with means for securing it to a chandelier, which preferably consists of a square boss 8, in which is formed a threaded aperture 8", which allows it to be screwed onto chandeliers or other light fixtures, and it is also essential that the socket shell be provided with an annular offset member 9, which I preferably make in the form of a projecting rib.

What has been said concerning artistic arrangement of the socket holder applies also to the shade holder. As illustrated, however, the lower end of the socket is provided with a plain square band portion 11, and close to its terminal end the annular rib 9 is formed on it to project from its surface. This annular rib 9 is of a curved or semi circular shape in cross section, and it extends entirely around the square lower end of the socket. Upon this lower end of the socket, I place a square band 12, which is made loose enough to slip over the rib 9. This square band is of metal, and like the socket and shade holder is preferably made of brass, but can be made of any other suitablernetal or material, and is made of a thin strip of spring sheet brass with its ends soldered or otherwise secured together, or it may be drawn from sheet metal, and at the center of each of its four sides I form a raised curved boss 13, by stamping or driving the metal outward-from the inside surface of the ring with a round pointed punch. This band I term a locking band, as its function is to lock the shade holder and the socket shell together, as will be presently described.

The shade holder comprises a square canopy shaped shell-like member comprising as illustrated a lower square fiat band por tion 14:, and four converging and upwardly sloping square portions 15, terminating in four vertical independent resilient wing portions 10, which are separated from each other at their corners by a recess 16, wide enough to give each a resilient movement without interfering with each other, and this recess may if desired be extended in the form of a slot along the corners of the sloping sides 15 of the shade holder, as an open slot as shown, as these corners are the points where the cuts are made when stamping this shade holder out of sheet brass, and they can if desired be closed up close together or be soldered or otherwise secured together.

The four vertical wings are each provided with a recess groove 17, that extends along the sides of each wing at its base, which are positioned in the same plane and register with each other. These grooves are formed by stamping the metal outwardly from the inside surface of the wings, and they are made of a curved or semi-circular form, and enough larger than the projecting ribs on the terminal end portion of the socket shell to fit freely and snugly over them, and these four spring wings are arranged to form a short sleeve portion on the top of the shade holder that is of a size to be sprung over the end of the socket and that will fit slidably and snugly over the end and the projecting rib of the socket, and then lie against the flat band portion of the socket adjacent to the rib. Then the locking band is pushed down over the spring ends of the shade cover, and is arranged to fit snug enough and with a resilient tension enough to remain on the spring ends against accidental displacement.

The socket shell and the shade holder are made separately, and are assembled together when it is desired to install and finish a residence or building with square sockets and shade holders.

The operation of assembling the parts is as follows: The socket and its non-conductive lining, I do not illustrate. They are, however, in the present state of the art mounted in the socket shell, which forms a casing for the socket, as is well understood, the cap portion of the socket being removable to permit the socket and its key and lining to be inserted in the socket shell. The key 18 is shown projecting from the side of Fig. 1, it being assumed that a socket is incased in the socket shell of this figure. When connecting the shade holder to the socket shell, the locking band is first placed on its lower end, and then the shade holder is pushed and sprung over onto the ribbed end of the socket shell, its spring ends readily yielding under pressure and springing over the end of the socket shell until the grooves in its wings fit over the ribs of the socket shell. Then the locking band is pressed down over the ends of the wings, thus firmly securing the two independent parts of my combined socket shell and shade holder together, and forming a combined square shaped socket shell and shade holder, of unique appearance, and one that can be manufactured and sold cheaply.

The different parts of my combined socket shell and shade holder are made by stamping or drawing them out into blank pieces, which are bent into the required shape, and their ends are then soldered or are otherwise secured together.

In Fig. 7 I illustrate the preferred manner of securing the ends of the shade holder together, which consists of a tongue member 19 on one end, and a slot 20 in the end of the opposite end, arranged to permit the tongue to be inserted in the slot and folded into a hook and flattened to clamp the two ends of the shade holder together.

My invention provides means for connecting square or cubic socket shells and shade holders of any square or cubic design or shape, and of different square or cubic designs or shapes to each other; and while I have illustrated a preferred construction and arrangement of my combined socket shell and shade holder connecting elements, I do not wish to be limited to the construction and arrangement shown, as many changes might be made without departing from the spirit of my invention.

Having described my invention, what I. claim as new and desire to secure by Letters Patent, is:

A shade-support for electric lamps, comprising a socket-shell square in cross-section and having a bead around its lower end, a shade-carrier having a rectangular baseportion, independent trapezoidal flaps e1- tending inward and upward from the respective sides of said base, each of said flaps having a transversely grooved vertically extending tongue adapted to be sprung over said bead along the respective side of said socket-shell, and a rectangular band around the socket-shell for maintaining said tongues against the sides of said socketshell.

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

HARRY WALLACE LAWRENCE.
