UNITED, STATES KORNEL o. BERGER,
OF NEW YORK, N. Y.
LAMP-SHADE FRAME.
Application filed April 11, 1925.
To all whom it may concern Be it known that I, KonNnL G. BERGER, a citizen of the United States of America, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Lamp-Shade Frame, of which the following is a full, clear, and exact description.
This invention relates to lamp shade frames, and is more particularly directed to an attaching bar forming )art of the frame.
The wire frames of bee lamp shades are generally manufactured and sold to jobbers, who in turn apply the lamp sockets and cords before supplying the same to the retailers. Formerly, tubular nipples were soldered in an eye formed in one of the cross wires of the frame structure, and this operation added materially to the expense of the manufacture and, furthermore, necessitated threading of the socket cord through the tubular nipple, in addition to the separation in many instances of the nipple from the frame because of the failure of the solder to properly secure the nipple in place. As a further development, flanges were provided, which proved unsatisfactory because of the fact that the tubular nipple carrying the flange became displaced and lost during transportation to the jobber. These nipples also required a disconnection of the wire terminal from either the socket or the plug to allow threading of the cord through the nipple.
In order to overcome the above enumerated disadvantages and objectionable features, the present invention has for its object the provision of an attaching bar having a loop with a mouth through which the cord may be readily inserted to permit the loop to be received by the usual socket nipple and locked in place by a set screw which is ordinarily adapted to secure the nipple to the usual electric fixtures connected with a lamp or a part of the building.
A further object of the invention is the provision of a device connected with a lamp shade frame for attaching the frame to a socket and which will permit of such attachment without necessitating the removal of the cord from either the socket or the attach} ing plug and without requiring any addi tional elements for the purpose.
The invention further comprehends th e provision of a'klamp shade socket attaching,
Serial No. 22,410.
device which is extremely simple in its construction, mexpensive to manufacture and readily applicable to a socket.
lVith the above recited and other objects in View, the invention resides in the novel construction set forth in the following specification, particularly pointed out in the ap pended claims and illustrated in the accompanying drawings, itbeing understood that the right is reserved to embodiments other than those actually illustrated herein, to the full extent indicated by the general meaning of the terms in which the claims are expressed.
In the drawings- Figure 1 is a front View of a lamp shade frame constructed according to the principles of my invention;
Figure 2 is a vertical transverse section taken along the line 22 of Figure 1;
Figure 3 is a vertical section taken along the line 33 of Figure 2;
Figure 4 is a vertical section taken along the line 4-4: of Figure 3; and
Figure 5 is a vertical section through the loop of the attaching bar of the frame.
Referring more particularly to the drawings, 1, 2, 3 and A generally designate the main bars of a frame of a shade normally adapted for use as a bed lamp and having the resilient clips 5 projecting rearwardly for securing the frame to the headboard of a bed. \Vhile I have shown a frame adapted for connection to a lamp shade frame for use on a bed, it must be understood that any lamp shade frame may be employed for the purpose, and particularly where it intended that the lamp shade frame is to be applied directly to a lamp socket. At any convenient points along the longitudinal bars 4, there is secured an attaching bar 6, which is provided with eyes 7 at its ends to receive the horizontal bars 4 of the frame. The ends of the bars are rigidly clamped to the bars 4- and are either soldered or welded as may be desired in order to prevent displacement of said bar.
The bar 6 is bent intermediate its ends to provide a circular loop 8 with the por tions of the bar, as shown at 9, where the loop is joined to the bar proper and spaced from each other to provide a mouth 10 through which the usual cord 11 of a socket 12 is adapted to be passed when applying the frame to said-socket. As shown more particularly in Figure 5, the circular loop portion 8 is provided with a cam groove 12 and a flange 18. The head of the usual set screw 14L is adapted to ride in the groove 12 and be engaged by the flange 13 for looking the loop 8 and likewise the attached frame to the socket.
In applying a frame provided with my improved attaching bar 6 and its securing loop 8, it is only necessary to insert the socket 12 through the usual open end of the lamp frame, pass the cord 11 through the mouth 10 of the loop 8 and so position the usual nipple 15 of the socket 12 within the loop 8 that the head of the set screw 14 will be in position to be received within the groove 12. It will be noted that the usual shoulder 16 on the socket adjacent the nipple 15 forms a seat for the loop 8 for positioning the groove 12 in alignment with the head of the set screw 14:. The socket is then turned bodily until the set screw is in the position shown in Figures 2 and 3 so that the head will contact with the flange l3 and force the same in rigid engagement with the shoulder 16 on the socket 12.
It will be seen by such a construction that it is only necessary to insert a lamp socket into the open end of the frame, place the nipple within the loop 8 and turn the socket, thus eliminating any auxiliary eleanents for aiding in connecting the frame to the socket.
Having thus described my invention, I claim:
1. As a new article of manufacture, a lamp shade frame provided with an attaching bar having a loop intermediate its ends to receive the attaching nippleof a lamp socket, said loop being provided with a mouth through which is adapted to be passed the conductor cord of the socket, and a groove furnishing a flange, said flange adapted to engage the head of the usual set screw on the nipple to prevent displacement of the frame from the socket.
2. As a new article of manufacture, a lamp shade frame, an attaching bar forming part of the frame, said bar being bent to provide an offset receiving loop for the attaching nipple of a lamp socket, the ends of the loop where oined to the body of the bar being spaced apart to furnish a free passage for the conductor cord of the socket, said loop having a locking flange adapted to'engage the usual set screw on the nipple of the lamp socket to prevent loss of frame from said socket.
8. As a new article of manufacture, a lamp shade frame provided with an attaching bar having a loop intermediate it ends to receive the attaching nipple of a lamp socket, said loop being provided with a mouth through which is adapted to be passed the conductor cord of the socket, a cam on the loop adapted to engage the usual set screw on the nipple for forcing the nipple tight against the loop.
4. As a new article of manufacture, a lamp shade frameprovided with an attaching bar having a loop intermediate its ends to receive the attaching nipple of a lamp socket, said loop being provided with a mouth through which is adapted to be passed the conductor cord of the socket, a flange on the loop having a cam surface adapted to engage the usual set screw on the attaching nipple for drawing the nipple tight against the loop when the nipple is turned in the loop.
