LAMP.

Specification of Letters Patent.

Patented Mar. 9, 1915.

To all whom it may concern:

Be it known that I, LINDsLEY SonErMons, a citizen of the United States, residing in Hasbrouck Heights, county of Bergen, and State of New Jersey, have invented new and useful Improvements in Lamps, of which the following is a description.

My invention pertains to that class of lamps wherein it is desired to support a source of illumination and direct the rays thereof in a predetermined manner.

As my invention is particularly applicable to lamps adapted to be supported from a ceiling or deck and cast most of their rays in a downward direction over considerable area, it will be described with respect to such a lamp.

In the drawing, Figure 1 represents a ver tical section and partial elevation of one form of lamp embodying my invention. Fig. 2 is a top plan of a bowl supporting member used in the type of lamp shown in Fig. 1.. Fig. 3 is an elevation of the bowl supporting member shown in Fig. 2. Fig. 4 shows a portion of the bowl supporting member shown in Figs. 2 and 3 and an elevation of a hinge employed in my lamp. Fig. 5 shows a portion of the bowl supporting member shown in Figs. 2 and 3 and an elevation of a latch employed in my lamp.

in the drawing, referring particularly to Fig. l, i represents a supporting spider con'iprehending an annular ring which may be secured in proper position against the deck or ceiling 2 as by means of bolts The said supporting member-1n spider is provided with a plurality of lens uniting the ring portion with the cents! threaded portion 5 into which screwed the nipple *7 which 2 y be held firmly in place as by lei-k nuts 7. The nipple carries the socket 8 adapted to properly support an electric lamp or bulb 9 wh ill may readily be wired as indicated in the figure 1.0 represents an ornamental shell or inelosing member cover ing the spider. n pple and socket and at cached to the spider or support n: in as by means of .ZJli l provided with a ihrca which made up the ih e presided with an im rnal lar ring portion which is attached to the member 12 as by means of screws 16. The fingers 15 are so shaped at their lower extremities that when they are pressed inwardly by the member 13 they will engage the flange or neck of a shade or reflector 17 and hold the same in a proper position.

The bowl supporting member or spider, comprising the annular portion 18 shown in Figs. 1, 2 and 3 and provided with depressions 19 to accommodate the heads of the screws 16, is attached to the member 10' as by means of screws 20. The said spider comprises a plurality of legs 21 supporting the annular ring 22, provided with a boss 23 which together with two ears or lugs 24,

shown in Fig. 4, cooperates with a pin 31 as indicated in'the said figure to form a hinge. The said bosses 2d are united as by rivets to a split ring 25 of sheet metal of substantially U-shaped section. The ends of the split ring are both attached to suitable lugs 26 which may be drawn toward each other as by means of the screw 27, shown in Fig. 5, which screw engages the latch 28 so as to hold the ring in proper position as indicated in Fig. 1. By removing the screw 27, the ring may be opened to receive the lip or flange of a suitable bowl 30 having its lip preferably covered for a portion thereof with an elasyic material 29, and when the ends of the rmg 25 are brought toward each other and the screw 27 made up the said screw will. firmly hold the bowl 30 in proper position Within the ring :25.

In placing my lam in service I prefer to proceed. in the following manner: The nipple i3 is first made up in the portion 5 of the supporting member 1 and firmly clamped 1!! place by means of the lock nuts 7. The sachet 8 is wired and then made up upon the nipple (S as saown in Fig. 1.. The wires may then he coupled up with an external circuit ll known manner. The supporting nuance-r l is then firmly made fast to the loci-i or ceiiing as by. means of the bolts or screw 3 and when in proper position I shell 16, ha ng the members 13 and roperly in place thereupon, over the -t and nipple and. into the position n is Fig. 1, in which position it may be -==l\"i by inserting and making up the the same downwardly and through the instrumentality of the internal conical bore 14, the members 15 are crowded into the recess in the neck or flange of the shade or reflector 17 in such manner as to hold the shade firmly in its proper position. I then place the bowl supporting spider with its ring 18 in proper position against the lower portion of the member 10 and insert the screws 20 which hold the said spider firmly in its proper relative position with respect to said member 10. By withdrawing the screw 27 the ring 25 may be opened and the lip of the bowl 30 insorted within the ring and then by replacing the screw 27 and making up the same the bowl 30 will be held firmly within the ring. The ring may then be placed in position with the members 2% on opposite sides of the lug 23 and the pin 31 inserted through the said members and the lug to cause the hinge to be properly assembled. Then if the bowl is swung into the position shown in Fig. 1, the latch or spring 28 will engage the screw 27 as shown in Figs. 1 and 5 and firmly hold the bowl in place. The bowl 30 and shade or reflector 17 may be of any desired materials and in practice I prefer to make both these members of a translucent reflecting material which will allow a portion of the rays from the lamp 9 to pass through the same but will reflect most of the rays for the following purpose: By making the shade or reflector 17 of a translucent or semi-transparent material, most of the rays falling upon the inner surface of the said member 17 are reflected downwardly more or less in a cone of large divergence so as to light a considerable area. However, a portion of the rays, by passing through the material of the reflector 17, will serve to light the deck or'celling sufliciently to make the same attractive. The bowl 30, if made of translucent material, will screen the source of illumination or bulb 9 sufliciently that, if looked at directly by an observer, no discomfort, due to intensity of light, will be experienced and the rays reflected by the owl 30 will, by striking the reflector 17, be reflected over considerable area as well as the direct rays from the bulb 9. Therefore, it will be noted that my invention produces a lamp which may be used for lighting in accordance with the now well known practice termed indirect illumination.

I do not wish in any way to limit myself to the exact details of construction set forth in this specification which is given to illustrate one type of lamp comprehending my invention, for it will be obvious that wide departure in the way of details may be made without departing from the spirit and scope of my invention which is as set forth in the following claims.
