The object of this. invention is to provide a simple inexpensive device whereby a book, paper or the like may be illuminated so that a reader may peruse the same without res quiring an entire room to be illuminated. The device is especially advantageous in dormitories or other places wherea number of persons may be assembled and one of the number may desire to read or work while theothers wish to sleep or rest without being disturbed, and a particular ob ect is to provide a device whereby a small lamp may be supported adjacent reading matter or work and will illuminate the same without lighting up the entire room in which it may be located. Theinvention is illustrated in the accompanying drawing and will be hereinafter fully set forth, the novel features being particularly pointed out in the appended to claim.

In the drawing: Figure 1 is a perspective view of one form of the invention;

Fig. 2 is an enlarged detail section;

Fig. 3 is a detail perspective yiew showing a lamp-holding element differing in details from the particular shown in Fig. 1;

Fig. 4 is a detail showing another form of lamp-holding element 80 the invention.

' In the form of the invention illustrated,

there is provided a tubular standard 1 having an open upper end and having an opening adjacent its lower end, the lower extremity of the wall of the tubular standard being compressed and flattened, as shown at 3, to facilitate the application of a clamp thereto. Insulated conductors 4: are inserted through the tubular standard, and these conductors are preferably so treated as to retain the form into which they may be bent at their Y upper portions, as indicated at 5. The eonductors are carried into a socket 6 wh1ch may be of any approved detailed construction- 46 and is preferably equipped with a reflecting shade 7 of semi-spherical form whereby it will house a lamp 8 in such manner that the light issuing from the lamp will be directed onto a book or work but will be prevented from spreading laterally so that the area illuminated will be confined to the reading space or the space upon which work is to be performed as, for instance, a drawing board.

Fitted upon the standard 1 is a bracket 9 which, in Fig. 1, is shown as a pair of parallel arms connected by a hub member 10 encircling the standard and held thereto by friction, or permanently, as may-be desired, by brazing or otherwise. Between the parallel arms 9 is pivotally secured'a lamp-holdmg arm 11 having a sleeve 12 at its outer end to encircle the socket 6. The flexible but.

comparatively stifl' quality ofthe upper portion of the conductors will cause the lamp to remain in the position in which it may be set, wh1le the pivotal connection of the arm 11 with the bracket 9 will permit the lamp to be easily adjusted so that the light therefrom will be directed onto the desired area. It will be understood that the arm 11 is frictionally held in its set relation to the. bracket 9, and this frictional engagement cooperates with the qualities of the portion 50f the conductors to maintain the adjustment of the lamp. I

Disposed against one side of the lower flattened extremity 3 of the standard is the upper end of a jaw '13 which constitutes the fixed member of a clamp adapted to engage a support, the .remainingmember or jaw of the clamp, 14:, being. pivoted to the jaw 13 and normally pressed to the same by a spring 15 coiled around the pivot of the jaws. A

set bolt 16' is inserted through the end of the fixed jaw 13 and the flattened extremity 3 of the standard and a set nut 17 is engaged over the end of this screw and turned home against the end of the standard so that, when the nut is turned'fully home, the parts will be firmly secured together, although the clasp consisting of the jaws 13 and 14 may be easily turned to any desired position relative to the standard. Iii many instances, the clamp 13, 14 may be engaged directly with a fixed support as, for instance, the back of a ary member. It is desirable, however, to provide a more extended .support, and to this end I provide the clasp consisting of two jaws 18, 19 pressed together by a spring 20 disposed between the shanks 30, 31 of the re- "spective jaws. The jaws18, 19 are flat and gaged. The jaw 18,is quite widesoas to,

,chair, a bed post or other relatively stationform an adequate supporting base while the jaw 19 is pivoted between lugs 33 on the lower jaw and is relatively narrow so that'it may fit between the jaws 13, 14. The clasp will thus be disposed at a right angle to the jaws 13 and 14 and may be engaged over the edge of a book or a drawing board so that the lamp will be supported immediately over the book or board. a

The lamp-holding element illustrated in Fig. 1 is intended more particularly for use where the lamp is to have a more or less permanent relation to the post but it is sometimes desirable to give a wider range of adjustment to the lamp, and, in such instance, the lamp-holding element shown in Fig. 3 may be advantageously employed.

In this construction, the member directly engaged with the lamp or the lamp socket comprises the parallel plates 21 connected at one end by a sleeve or hub member 22 adapted 'to encircle the'lamp socket and pivotally attached at their free ends to one member 23 of a clas adapted to t around the standard. The movable member 25 of this clasp has one end oifset, as shown at 26, whereby it may be easily manipulated, and a spring coiled around the pivotal connection between the two members tends to hold the jaws 24 closed so that they will fit tightly about the standard. This lam holder may be very easily adjusted to a esired point along the height of the standard or it may be released therefrom and engaged with some stationary object at a convenient point relatively remote from the standard so. that the light from the lamp may he directed onto any particular object desired or otherwise most advantageously utilized. 7

In Fig. 4, the hollow standard 34 is formed at its upper end with a bend or elbow 35 having a convex rib or ball element 36 at its extremity. The socket 37 is'fitted at one end about the rib 36, so as to have universal movement thereon, and at its opposite end carries the shade and reflector 38 which corresponds in all respects to the reflector 7. The lamp is engagedin the socket in the usual manner. 39 denotes a clip or pin sewhich has circular jaws 24- cured on the standard 34 to permit it to be suspended on a'coat or other, article of wearing apparel. I

It will be understood, of course, that the readinn' lamp of my invention is to be energized a transformer of :any known commercial type will be interposed in the feeding con ductors 4. so that the current will be reduced to the capacity of the lamp and thereby avoid rapid burning out of the same, it being from the usual house current and that the purpose of the invention to utilize a very small bulb so that the illumination will be confined to the restricted area desired, such as a drawing, a hooker a page of a newspaper or the like. The arrangement illustrated for mounting the lam upon the standard and for supporting t e standard upon a relatively stationary object permits the device to be easily adjusted to meet various conditions and the construction is.

standard whereby to pivotally connect the member to the standard, a nut mounted on the bolt and tightened against the standard, a jaw engaged between and held by the members of the clamp, a second jaw pivoted to said first mentioned jaw, and means for maintaining the relatively stationary object.

In testimony whereof I aflix my signature.
