WILLIAM FLOYD, OF SYRACUSE, NEW YORK.

COMBINED REFLECTOR AND SHADE.

Application filed May 16, 1927. SerialNo. 191.829.

This invention relates to trouble lamps and aims among'other objects to provide a trouble lamp with improved means for automatically shielding the operators eyes and 5 for reflecting the light on the work.

In the drawings illustrating a preferred embodiment of the invention:

' Figure 1 is a perspective view of a trouble lamp embodying the invention;

Fig. 2 is a fragmentary longitudinal sectional view showing a portion of the cage, shade and the adjustable counterweight.

Fig. 3 is a sectional View takenon the line 3-3 of Fig. 2.

Fig. 4 is a sectional view of the shade locking means shown in Fig. 1; and

ig. 5 is a sectional View taken on the line 5.-5 of Fig. 4.

When using the present troublelamps, the 2 operators eyes are continually subjected to the rays thereof and while this objection may be overcome to a certain extent by putting-a piece of cardboard or other make shift arrangement in the cage to partly surround the 25 light, yetwhen the light is placed on' the floor or any other surface it has a tendency to roll and consequently the improvised shade is of little value. The present invention seeks to eliminate such faults by providing a combined reflector and shade which may be adjusted to automatically shield the operators e es and to reflect the light at any angle, even though the lamp may accidentally roll or move.

3 In'carrying out the invention, a reflector or I shade is suitably counterbalanced an mounted for oscillation within the cage of a trouble lamp. In its preferred form it is semi-cylindrical and somewhat longer than the bulb used and is mounted on a frame carrying an adjustable weight 11, which frame is manner to the disk 23 is a block 32 provided supported in a bearing 12 carried by the cage.

There is also rovided a spring-pressed plunger 13 whic may be -brought into fric- 15 tional engagement with the shade 10 to hold the latter fixed to the cage.

The frame for supporting the shade is formed in the present instance of three paral-.

lel wires

14, 15 and 16 which are equidistant from the longitudinal axis of the trouble lamp and secured at one end to a ring 17. Two of the wires 14 and 15 are diametrically opposite to each other andf it is to these and a portiqn 0f the ring that the shade 10 is secured. The other wire 16, which is midway between thewires 14 and 15 and opposite the shade 10,

is extended beyond the shade and bent inwardly as at 18 and then outwardly along the longitudinal axis of the trouble lamp to form a shaft 19, which is mounted for rotation in the bearing 12. The wires 14 and 15 are also extended beyond the shade and are bent inwardly and rigidly secured to the inner end of the shaft 19.

The trouble lamp is of conventional construction having a handle 20' provided with a socket 21 for holding a bulb 22, and which handle also has a flanged disk 23 secured thereto for supporting a cage which is formed of wires 24 secured to

rings

25 and 26. The alternate wires 24 of the cage are extended beyond the ring 26 and then bent inwardly and rigidly secured to the bearing 12. 'Theadjustable weight 11, which is heavier than the shade, is shown as secured to or made integral with a'disk27, which is suitably apertured for rotation on the shaft 19 and is provided on its inner face with radial teeth 28 adapted to coact with similar teeth 29 on the outer face of a disk 30, rigidly mounted on the shaft 19. An expansile coil spring is mounted on the shaft 19 between the disk 27 and a washer 31, rigidly secured to the shaft 19 adjacent the bearing 12 to hold the disk 27 in locking engagement with the disk 30. By this arrangement it will be seen that the welght maybe adjusted about the shaft 19 by pushing it against the tension of the spring andswinglng it about the shaft in either direc 1on.

As shown in Fig. 3 the weight is in posi- 1 tion to hold the shade 10 directly above the bulb 22 and as the weight overbalances it,

the' shade will always remain in this position even though the light should accidentally roll on the

rings

25 and 26 or be moved about. Formed integral with or secured in any is bent at right angles to the plunger 13 to.

form a leg 36 which coacts with the shade 10. When the shade is to be automatic in 1ts operation, the plunger is pulled outwardly and the end 34 is seated in an arcuate recess 2. In a device of the character described, so

37 of less depth than the recess 35. When the shade is to be fixed with -respect to the,

cage it is only necessary to turn the handle 5 unti the end v34 drops into the recess. 35, thereby allowing the leg 36 to engage the shade 10. a

From the foregoing description, it will be apparent that the improved trouble light is e to manufacture, simple in its operation an efiective in its use.

Obviously, the present invention is not restricted to the particular embodiment \thereof herein shown and described. Moreover, it is not indispensable that all the features of the invention be used conjointly, since they may be employed advantageously in various combinations and sub-combinations.

What is claimed is 1. In a device of the character described, an open cage for an electric lamp; a shade mounted for oscillation within the cage; 21 counterbalanced weight connected to said 25 shade to automatically maintain the same in its initial radial relation to the longitudinal axis of the cage while the cage may move relative to the shade; and means whereby the shade may be locked to the cage.

an opencage for an electric lam a shade inounted for oscillation within t e cage; a counterbalancing weight, connected to said shade to hold thesame in adjusted position; and a spring pressed plun er carried by said 3 cage to lock the shade to t e cage.

3. An open cage for an electric lamp provided at one end with "a bearing; a shade within the cage; a shaft j'ourna'led in said bearing and rigidly'secured to said shade; a weight journaled on said shaft; a disk rigidly secured to said shaft; and meansto lock theweight to the disk to counterbalance the sha e.-

4. An open cage for an electric lamp provided at one end with a. bearing; ashade within said cage; a frame for supporting said shade; a shaft secured to one end of the frame and" journaled in said bearing; a weight journaled on said shaft; and means 50 for adjustably locking the weight to the shaft to counterbalance the shade.

In testimony, that I claim the, foregoing as my own. I have hereto aflixed my signature.
