rlhe present invention relates to shadeholders and is more particularly directed toward a form ot' shadeholder suitable for support-l ing metal shades common in industrial lighting units and for providing a water proo housing orthe lamp socket.
An object of the present invention is to provide a shadeholder ot the above character, the shadeholding parts of which may be made out Ot cooperative sheet metal stampings which may be readily'assembled and which are not likely to get out of order or become disassembled, and in which one may easily release or tasten a shade without the use of tools.
A further object of the invention is to provide an improved lconstruction of the shadeholder and socket cover which may be readily supported about the socket.
@ther and further objects of the invention will appear as the descriptionproceeds.
The accompanying drawings show, 'for purposes of illustrating the invention, one of the many possible embodiments in which it may take torm,it being understood that the drawings are illustrative of the invention rather than limiting the same'.
1n these drawings:
Figure 1 is a vertical the shadeholder, parts being in elevation;
Figure 2 is a sectional view on the line 22 ot Figure 1 looking in the direction of the arrows;
y Figure 3 is a sectionron the line 3*-3 of Figure 1 looking in the direction of the arrows showing the parts in position for clamping a shade;
Figure 4 is a perspective view of the lower portion or' the socket cover; and
Figure 5 is a perspective view of the -movable ring used in actuating the shadeholding elements.
A two part conventional porcelain lamp socket is indicated at and 11. A stud 12 is 'fastened to the upper end of the lamp socket by screws indicated at 13. The stud 12 is insectional view through `tern ally threaded as indicated at 14 so that the socket may be carried :trom a suitable sup-y p rThe lower part of the stud is out-k Ort. vardly flanged as indicated at 15, while the intermediate part is, as here shown at 16, hexagonal, and the upper end is reduced and threaded as indicated at 17.
An inverted cup-shaped sheet metal stampw ing 18 surrounds the socket, acts as a socket 5D cover and is provided at the lower end with 1926. Serial No. 117,979.
shadeholding devices.` 'The upper end 1.9 of the stamping 18 has a non-circular hole which its about the hexagonal portion of the stud i and the end of the stamping rests on the flange 15. A cap 20 is threaded onto the outside of 60 the stud and comes down onto it and engages with the upper end of the stamping to clamp it in place. The lower end 21 of the stamping 18 extends a short distance below the loWer end of the lamp socket. It is provided with a plurality of flexible tongues 22 which are pressed from the material of the stamping. The upper sides of these tongues are tapered as indicated at 22 and their ends 23 are bent slightly outward. n
A ring 24 has an inner wall 25 which fits about the lower-end of the stamping 18. This inner wall` has a number ot apertures 2G through which the spring tongues 22 project. The outertwall 27 ot' the ring is spaced suiii 75 ciently from the inner Wall to accommodate the bead or lip 28 of a shade.
As clearly indicated in the drawing, the flexible tongues project `outwardly through the apertures or slots 26. These slots are short so that the opposite faces of the tongues are engageable with the opposite ends of the slots. 'When one turns a ring in a direction to clamp the shade,y it causes the flexible spring tongues to travel along the slots and 35 effects a camming action upon the tongues to move them outwardly to the position of Fig-` ures 1 and 2 bringing the upper edges of the tonguespagainst the end iiange of the shade and directly supporting the shade from the 9U stamped socket cover. The thickness of these tongues is greater than the clearance between the inner Wall 25 of the ring and the bead of the reflector. Owing to the oblique upper edge of the spring tongues, the reflector will be clamped tightly .against the upper part of the ring. This wedges the parts together, compensates for varying thicknesses 'of enamel, and does not make the supportdependentupon spring eX- pansion. When one turns the ring in the oposite direction, the spring fingers will be y compelled to retreat and release the shade. i
1n order to contine the ring and prevent its moving upwardly along the stamping 18, the stamping is preferably provided witha bead indicated at 29. To limit the angular movement of the ring and prevent its acci dental removal, an inwardly directed prong 30 is carried on the inside wall 25 of the ring. 110
ing of the shade It projects into a slot 3l in the skirt 2l of the stamping 18. In assembling these parts, the stamping 18 is pressed suiiiciently to permit .the prong 30 to be pushed into position.
It will be noted, that the shadeholder which has just been descrioed is made oit a smal number of simple parts which may be readily assembled and which are well suited for the purpose of covering the socket and supporting a shade from the stud which supports the socket so that no strain is placed on the socket itself. No amount oit jarring or vibration will disengage the parts.
It is obvious that the invention may bc embodied in many forms and constructions within the scope of the claims, and I wish it to be understood that the particular form shown is but one of thc many i'orms. Various modilications and changes being possible, I do not otherwise limit myself in any way with respect thereto.
