B %Ww/ZQVM+ Wm W l atented Aug. 21, 1951 UNITED STATES PATENT OFFICE HOLDER ASSEMBLY FOR REFLECTOR TYPE FLOOR LAMPS 4 Claims.

This invention has to do with reflector type floor lamps and is particularly concerned with improvements in the holder assemblies employed in such lamps.

An object of the invention is to provide an improved holder assembly which is inexpensive to manufacture, which is strong, rigid and durable and which may be very easily and quickly assembled and wired.

Another object of the invention is to provide a holder assembly wherein the reflector lamp socket is secured on a detachable mounting which is adapted to be rigidly connected to the body of the holder whereby the socket may be assembled with the body of the holder and secured in rigid position therein after the wiring is completed.

A more specific object of the invention is to provide in a holder assembly which comprises a body or base portion and a reflector lamp socket, a two-part detachable mounting bracket which is adapted to be initially loosely connected to the reflector socket and which is thereafter attached to mounting tongues provided in the body portion by relative rotation of the reflector socket and the body portion and secured thereto in rigid clamping relation. 7

These and other objects of the invention will be apparent to those skilled in the art upon a full understanding of the construction and arrangement of the parts of the preferred form of the holder assembly which is shown by way of illustration in the accompanying drawings, wherein:

Fig. 1 is a side view of a holder assembly embodying the principles of the invention;

Fig. 2 is a vertical section through the center of the assembly showing the reflector lamp socket in side elevation;

Fig. 3 is a horizontal section through the assembly, taken on the line 3-3 of Fig. 2; and

Figs. 4 and 5 are perspective views of the two strap members which form the mounting bracket for the reflector lamp socket.

Referring to the drawings, the holder assembly includes a hollow upwardly opening cup-shaped sheet metal body In which is provided with a plurality of radially extending tubular arms H for the reception of wires (not shown) leading to lamp sockets (not shown) on the outer ends of the arms. The body [0 is provided with an aperture l2 in the center of the bottom to permit it to be connected to a standard l3 which supports the assembly. Inturned tongues or lugs M are formed adjacent the top edge or rim of the body In and extend in opposed relation a short distance within the same to detachably receive a mounting bracket [5.

The mounting bracket l5 consists of a relatively narrow two-part strap member which is provided for supporting a centrally arranged upwardly opening reflector lamp socket [6. The socket l6, which may be of any suitable construction, is preferably secured to the strap I5 by means of screws I! the threaded ends of which extend downwardly from the base thereof. The mounting strap I5 comprises two relatively narrow rectangular sheet metal members l8 and I9 (Figs. 4 and 5). The bottom member !9 is provided with a central aperture '20 and two laterally spaced apertures 2!. The apertures 2| are threaded for engagement with the threaded ends ofthe screws 11. The corners of the bottom plate !9 are curved downwardly at 22' to more easily position the ends of the strap in encompassing relation with the tongues 14. The ends 23 of the bottom plate [9 are provided with a curvature approximately the same as the curvature of the body member H3. The top plate member I8 is centrally apertured and sleeved out at 24, the sleeved portion being passed through the aperture 2! in the lower plate l9 and turned over to loosely connect the members l8 and I9 (Fig. 2). The plate member 18 is provided with laterally disposed apertures 25 which are of sufficient diameter to pass threaded ends of the screws H. The ends of the member 25 are given the curvature of the body member Ill and provided with recesses or socket formations 26 which are adapted to receive the inturned tongues M on the body member ID.

In assembling and wiring the holder, the mounting strap I5 is first loosely connected to the socket It by engaging the ends of screws H in the apertures 2|. The assembly is then wired in the usual manner, the socket It being merely positioned relatively close to the body It). After the wiring is completed the socket [6, with the strap member 15 loosely attached, is positioned relative to the body It! as indicated in dotted lines in Fig. 3, so that upon rotation of the socket I6 the tongues M will enter between the ends of plates l8 and I9 and engage in the recesses 26 being guided by the downturned corners 22 of the bottom plate IS. The recesses 26 are of less depth than the thickness of the tongues It so that tongues [4 are rigidly clamped between the plates 18 and I9 by tightening the screws H.

The holder assembly also includes a vertical removable sheet metal shell 21 which surrounds the socket [6. The shell 21 is preferably the same diameter as the body I and is provided with an annular seat 28 adapted to engage the top edge of the body [0. An ornamental bead 29 is formed on the lower edge of the shell 21 and extends over the edge of the body ID. The bead 29 is provided with straight edge portions or openings 30 for receiving protuberances 3| on the body 16 to'detachably secure the shell to the rim of the body. lhe shell 21 is attached to the body I 0 by aligning the openings 38 with the protuberances 3| and moving the shell downwardly to position the protuberances in the internal groove formed by the bead 29 after which the shell. is turned to provide interlocking engagement of the protuberances 3! in the groove. The shell 21 is provided with a lateral aperture (not shown) for accommodating a switch finger piece (not shown) extending from the side of the socket [6. The shell 21 is provided at its upper edge with a plurality of set screws 32 for locking engagement with a reflector bowl 33 carried by the shell.

The arrangement of the socket mounting strap I5 so that it may be initially loosely attached to the socket [6 provides initial accessibility of the parts for easy and rapid wiring of the assembly. When the wiring is completed, the assembly of the socket with the body ['0 is completed by a simple rotative movement after which it is rigidly secured in position by merely tightening the screws H. The strap l5 provides a rigid brace across the top of the body It] while at the same time centering and rigidly mounting the socket Hi. The strap I5 is relatively narrow so that it permits free circulation of air through the holes 34 in the base In and upwardly around the socket It.

The mounting strap is illustrated as flat but it may be bowed or provided with a raised center portion to position the socket [6 at any desired elevation relative to the base It. Also a less expensive socket of smaller cross sectional diameter may be used with the strap 15 by providing threads in the aperture 24 of the top plate I8 for receiving the threaded lower end of a mounting stem conventionally provided in such a socket. In using the strap 15 with this type of socket shorter screws I! would be provided which would not extend through the base of the socket but which would be accessible at the sides of the socket.

When the holder has been completely assembled and it is desired to disassemble the same the clamping screws ll are loosened and the socket 16 is raised to withdraw the tongues M from the recesses 26 in the top plate I8 whereupon the socket it may be rotated to completely disengage the strap IE from the tongues l4.

While specific details of construction and materials have been referred to in describing the illustrated form of the invention, it will-be understood that other details of construction and other materials may be resorted to within the spirit of the invention.
