LAMP REMOVER Filed April 1, 1964 2 Sheets-Sheet 2 IIH | I 30 I l INVENTOR WILLIAM W. CLAPP BY Jazz/2mm. WM,JMWZM ATTORNEYS United States Patent 3,232,658 LAMP REP/EGVER William W. Clapp, 1745 Bellaire Drive, Casper, Wyo- Filed Apr. 1, 1964, Ser. No. 356,481 4 Claims. (6!. 294-20) This invention provides a device for engaging and removing the various parts of an overhead lamp assembly, which may include a downwardly reflecting shade, a wire mesh guard, a globe within the guard, and a lamp bulb Within the globe. By the use of a device provided by this invention any one or all of these parts of an overhead lamp may be engaged by a simple adjustment of parts of the device and may be separately removed and replaced.

The invention is described in the following specification and is illustrated in the accompanying drawings in which:

FIG. 1 is a perspective view of the lamp changer tool provided by the invention;

FIG. 2 is a side elevational view of the lamp changer in position to remove a lamp guard and shade;

FIG. 3 is a side view of the lamp changer showing parts thereof in position to remove a lamp globe;

FIG. 4 is a side view of the lamp changer showing parts thereof in position to remove a lamp bulb;

FIG. 5 is a perspective view of one of the two parts of the lamp changer which is moved into position to engage a lamp bulb;

FIG. 6 is a perspective view of the part of the lamp changer which receives and holds the device shown in FIG. 5, and

FIG. 7 is a perspective view showing the parts of the lamp holder which engage a wire guard.

The device or tool which I have provided comprises a part for engaging the elements of the lamp assembly, this part being indicated at A in the drawings and being mounted on the end of an elongated handle B by which the lamp engaging the part A may be raised into engagement with the overhead lamp assembly.

The part A of the device is generally hemi-spherical in shape having a circular upper part 2 formed preferably of strip metal to which are attached at equal intervals four metal strips 4, 6, 8, 19 which depend from the circular member 2. The strip 2 is permanently attached to one of the depending strips, this being strip 18, and is slidably attached to the other depending strips 4, 6, 8 by straps 11. These depending strips are curved arcuately inwardly at their lower ends for attachment to the handle B. As shown at 12 in FIG. 1, the ends of the circular strip 2 which forms the open upper end of the tool are overlapped and are movable with respect to each other to permit the transverse size of the tool to be varied in order to accommodate it to lamp assemblies of different sizes. An extension spring 14 is mounted between lugs 16, 18 on the adjacent overlapping ends of member 2 and constantly urges the ends of the strip toward each other to a condition of minimum size of the tool. The overlapped ends of the strip may be pulled apart against the force of spring 14 and will be held in such adjusted position by friction. The depth of the tool is such that it will be accommodated to overhead lamp assemblies of the type and having the parts described above.

Means are provided by the invention for engaging the wire mesh of a lamp guard such as that shown at 20 in FIG. 2. Such means comprise two upstanding lugs 22, 24 which are attached to the diametrically opposite depending strips 4, 8 and are positioned on such strips adjacent their juncture with the handle B. Each of these upstanding lugs is provided with an upwardly opening L- shaped aperture 26 and the two apertures face oppositely to each other so that the diametrically opposite wires Cir at the lower part of a guard may be received within the apertures after which the tool may be turned to engage the wires of the guard within the apertures, after which a further turning of the tool will unlatch the wire guard and permit it to be removed. As shown in FIG. 2, the usual downwardly reflecting lamp shade is attached in most cases to the wire guard and will be removed with it.

After removal of the wire guard the globe 30 which surrounds the light bulb must be removed and the tool provided by the invention includes means for effecting this. Such means comprise two straps 32, 34 which are attached by their ends to diametrically opposite parts of the circular upper strip 2 on the outer surface thereof. Each of these straps has downwardly converting side walls and an outer wall which is spaced from and generally parallel to the circular member 2, and these walls define an opening of rectangular cross section. A filler member 36 is positioned within the opening defined by each strap and is held therein by a pin 38. The thickness of each filler member is such that an inner opening 40 is left between the circular member 2 and the inner surface of each filler and a second or outer opening 42 is left between each filler and the outer wall of each strap. Associated with the tool and the forming part thereof are two flap members, each of which comprises a central plate part 5%} having hinged to one end a flat, wedge shaped member 52 which may be selectively received in either of the openings 40, 42 which are respectively outside and inside the filler member 36 which is positioned within each of the straps. At its outer end the plate 50 has hinged thereto a strip member 54 to which there is attached an arcuate member 56. It will be seen that if the wedge shaped members are positioned within the openings 42 between the outer surface of earth filler member 36 and the outer wall of the strap and the arcuate members 56 are permitted to lie within the tool, as shown in FIG. 1, the arcuate member will be spaced apart by a maximum distance which will permit the two opposite arcuate members 56 to engage the globe which surrounds the light bulb. If now the two Wedge-shaped plate members 52 are removed from the outer recesses 42 and positioned within the inner recesses 46, as shown in FIG. 4, the arcuate members 56 will be a minimum distance apart and will therefore engage the lamp bulb. In each of the two positions of the arcuate members 56 the tool may be turned in order to unscrew either the globe or the lamp bulb, and in order to facilitate this the inner surface of each of the arcuate members 56 is coated with rubber or some other frictional material.

It is believed that the construction and operation of the tool provided by the invention will be apparent from the foregoing description and that no further description of operation is required.

While I have described and illustrated one embodiment of the invention, it will be apparent to those skilled in the arts to which it relates that other embodiments, as well as modifications of that disclosed, may be made and practiced without departing in any way from the spirit or scope of the invention, for the limits of which reference must be made to the appended claims.

What is claimed is:
