His 2. primary object of the invention to provide a novel and simple lamp or-like appliance of virtually universal application. A lamp made in accordance with the present invention has a specialbase whereby it maybe permanentlymounted on a wall or elsewhere; it may serve as a pin. up lamp; itmay be set on a table or-other support; it may be manipulated by hand; or it may be clipped to the back ofv a chair or some other support of that type. It is particularly adapted for use with spot bulbs such'asare used for show window lighting and for special infra red or ultra-violet radiation.
In all positions and mountingsofthe base, the socket is adjustable to a varietyof angles and the provision of a novel and simplified pivotal connection, permitting the adjustment. of; the socket and its retention in adjusted position, is another object of the invention.
Still other objects will be apparent from the following disclosure.

For hanging the lamp from a chair back or any other similar support, the operator simply pivots the spring hook 35 outwardly about the rivet 36 which connects it to flange 33. In this position the spring hook 35 may readily be engaged over any such object as rail 38 (Fig. thereby to support the disk 21, with respect to which the lamp base [0 and lamp are pivotally adjustable to the desired position.
However the lamp is supported or mounted, the shell and socket are pivotally adjustable on the standard M to any desired position respecting the base. The electrical connections do not interfere with such adjustment inasmuch as the cord 40 leading to socket I! does not pass through the standard but directly enters shell I61 through a'suitable opening provided therein at .39.
The lamp as disclosed is not only light and conveniently adjustable, but is well adapted to be held in the hand for manipulation of the rays emanating from a bulb mounted in the socket thereof. It is further to be noted that the pivotal adjustment of the socket shell respecting the standard is upon an axis substantially at right angles to the axis upon which the standard is pivotally adjustable respecting the mounting element 21. Appropriate manipulation of the parts about these axes at right angles to each other enables the socket to be given substantially universal adjustment respecting the mounting element whether such mounting element is suspended or permanently fixed to the wall, or whether it is hooked to a support as shown in Fig. 5. r 1
