1 Claim.

lamp may be firmly held during its application to or removal from the lamp socket.

A further object of the invention is to provide a lamp applying and removing device which may be effectively employed in association with lamps positioned on high ceilings, yet which may be quickly and easily separated into its components, to facilitate convenient storage when not in use.

An additional object of the invention is to provide a lamp applying and removing device which is simple in construction and operation, and which will not easily become-damaged.

A still further object of the invention is to provide a lamp applying and removing device which will readily lend itself to economical manufacture.

With the above more important objects in View, and such other objects as may become apparent as this specification proceeds, the invention consists essentially of the arrangement and construction of parts as illustrated in the accompanying drawings, in which:

Figure 1 is an underside plan view of the invention Figure 2 is a side elevation thereof Figure 3 is a cross-sectional View, taken substantially in the plane of the line 33 in Figure 2 Figure 4 is a fragmentary elevationalview of an extension rod used in the invention, and

Figure 5 is a developed view of a metallic blank from which a component of the invention is formed.

Like characters of reference are used to designate like parts in the specification and throughout the several views.

Referring now to the accompanying drawings in detail, the invention consists of a lamp applying and removing device designated generally by the reference character ill, the same embodying in its construct on, a clamp-like socket H, adapted for removable positioning upon one end of an extension rod l2. The free end portions it of the socket are connected together by a clamping bolt and wing nut designated collectively by the reference character 14, whereby the socket may be attached to or detached from the rod l2, as will be clearly understood.

A plurality of equally spaced, resilient fingers l5 are formed integrally with the clamp l 5, these fingers being arcuated substantially as shown and forming a bulbous cage designated generally by the reference character Hi.

This cage is adapted to removably receive the incandescent lamp ll, and it will be noted that the free end portions of the fingers l5 are outwardly curled as at !8, to facilitate the insertion of the lamp thereinto, and to provide what may be referred to as retaining loops, designated by the same reference character (18).

A coil spring l9, arranged in a continuous circular formation passes through the loops l8, whereby the fingers l5 are urged together.

When the invention is placed in use, the cage !5 is engaged with the bulb ll as aforesaid, whereupon by simply rotating the rod !2, the bulb may be installed in its socket, or alternatively, removed therefrom.

If desired, the rod l2 may be formed from a plurality of longitudinally alignedsections 2%, the end portions of which are threaded as at H. A plurality of threaded couplings 22 may be employed for separably connecting the adjacent ends of the section 29, whereby the rod l2 may be of sufficient length to facilitate insertion and removal of lamps positioned on high ceilings. When the invention is not in use, the sections Ztlmay, of course, be separated and the cage l2, together with the clamp l I, removed, to facilitate convenient storage.

It is believed that the advantages and use of the invention will be clearly understood from the foregoing disclosure and accordingly, further description thereof at this point is considered unnecessary.

While in the foregoing there has been shown and described the preferred embodiment of this invention it is to be understood that minor changes in the details of construction, combination and arrangement of parts maybe resorted to without departing from the spirit and scope of the invention as claimed.

What I claim as my invention is:

An incandescent lamp applying and removing device, comprising, an extension rod, a clamp-like socket removably secured at one end of said rod,

3 formed of a plurality of resilient fingers integral UNITED STATES PATENTS with and extending from a strip and forming a Number Name Date bulbous cage,'the free extremities of said fingers 197 509 Abbott 27, 1877 being outwardly curled and forming retainin 1 658017 Gmmeu Jan 31 1928 loops, and a coil spring arranged in a continuous 5 1823170 Schulz Sept 15 1931 circular formation, said spring passing through said loops and urging said fingers together, the FOREIGN PATENTS terminal portions of said strip being bent, means Number Country Date extending through the bent portions for squeezing 4,761 Great Britain 13, 1397 said portions in frictionally clamping manner 10 of 1396 around said rod.
