lLUG REMOVEE.

Specification of Letters Patent. Patgntgd June 27', 1916 'ipglication filed March 10, 1918. Serial No. 83,329.

Z'o al. m wm. 1' may concern:

Be it known that 1, WILLIAM J. LeisER, a citizen of the United States, residing at Chicago, in the county of Cook and State oTIllinois, have invented certain new and useful Improvements in Plug l iemovers; and I do hereby declare the following to he a full, clear, and exact description of the in.- vention, such as will enable others skilled in the artto which it appertains to make and use the same.

This invention has for its primary object to provide a simple and efficient device for facilitating the removal and attachment oi plugs from and to electric lamp sockets.

it is. a W ll known fact that it is difiicult to remove or attach a. plug to an electric incandesccnt lamp socket to wl'ii'ch is attached f so a shade or reflector, and it isftherefore, the objectof this invention to provide a. device for facilitating attachment and removal of the plug from a lamp socket, which on account of a shade or reflect-or or for any other reason is rendered inaccessible.

W'ith these and other objects in view, the invention consists in the novel. construction, combination and arrangement of parts will he hereinafter specifically described,

claimed and illustrated. in the accompany-- ing drawing, in which:

Figure 1 represents a side elevation of the improved plug, remover applied to use, Fig. 2 represents a perspective view thereof, the split plug-cnga ing ring heing removed, Fig. 3 "presents a bottom pl an vieW of the remover, T e reprcsea transverse sectional view on tie line i i otl ig. 1, Fig. 5 represents a pcrsp tive Vi-( of a modified type of the pi remover and plug removed therefrom, the later having a. recessed head particularly desi ned for use in connection with a. plug remover of this type, Fig. l

represents a transverse sectional view on the line *36 of Fig. and l ig. 7 represents a longitudinal sectional view tl'n'ough one of the spring arms and the slidahle ring associated therewith.

Referring to the drawing in detail, wherein similar reference numerals desig natc corrcspoiuliug parts throughout the several views. the numeral 5 indicates a ring preterahly formed from sheet metal and having one end reduced and curved to define a hook -13 adapted to he. received ithin an aperture flormcd in the other end, whereby plugs 1i,

gagcuicnt-in an aperture 22 indicated at 10, and crimped to define a U-shaped retaining;

plurality of terminal members 11. A split and contractible spring ring 12 is engaged in the U-shaped members 11 carried by the spring arms and is concave convex in cross section, the

concave surface 13 thereof being disposed .inwardly and adapted for engagement with the usual circumferential head or enlargement formed upon the usual types of socket carrying the usual extension Wire 15. The parallel portions of the arms 8 constitute handles adapted to be gripped in the hand of the operator to facilitate use of the plug remover.

In applying the invention to use the free ends of the ring 5 are separated and the extension wire l5'of the plug 14 is inserted in the ring. The spring arms 8 are subsequentlyspread apart'so as to expand the I plug-engaging ring l2,which latter is slipped over the circumferential bead of the plug 142 and the handles or arms 8 subsequently movedtogether sons to contract the band 12 and frictionally grip the socket 14. With the socket 142 thus held against rotarv aovement with relation to the free ends of the arms 8 the device is rotated, thereby unscrewing or attaching the plug as desired. the ring 12 may be apertured and formed with internal screw threads to receive a. thumb screw 16, whereby the ring may be permanently attached to the lamp plu Referring to the modification of the invention illust 'ated in Figs. 5 to 7, wherein is illustrated a. modification of the plug remover, the numeral 20 indicates a split ring having one end reduced and curved to provide a connecting hook 2], adapted for enin the opposite. end to detachahlv connect the ends ofthe ring. A plurality 111' spring arms QZlare i -idl connected atone end by rivets or equivalent means 24; in spaced relation to the. ring 20, extend outwardly from the latter in diverging planes and are curved at their free ends to define terminal U-shaped If preferred, the free ends of clamping members 25 adapted for engages ment in recesses 26 formed in the external head 27 of the socket plugs'28. The free ends of the spring arms 23 carrying the members 25 are adapted to be moved inwardly against their tension so as to firmly engage the recessed bead 27 by a ring 29, slida bly mounted over the arms. The movement of the ring 29 longitudinally of the spring arms 23 and in the direction of the ring 20 is limited by angular stop members 30 fastened to the spring arms adjacent the ring 20. The portions out the spring arms 23 intermediate the stops 30 and the clamping members 25 are crimped or corrugated and adapted to receive in the grooves de fined by the corrugations an internal bead 31 formed in the ring 29, whereby the latter is yieldably retained in adjusted position with relation to the arms and the clamping members 25 may be thus retained in permanent engagement With the bead 27.

What I claim is: p

1. A plug remover including a ring, means for detachably connecting the adjacent ends of said ring, a plurality of spring arms carried by said ring and a contractible spring plug-engaging ring engaged with the ends of said. arms opposite the first-mentioned ring.

2. A plug remover including a. ring, a

Copies oi this patent may be obtained for Are messes plurality of spring phig-engaging'wnns connected atone end with said ringgand having transverse corrugations, and means m'ovable over the corrugated portions of sand arms for drawing the free ends of the latter into frictional engagement with a plug.

3. A plug remover including a ring, a

plurality of spring arms connected at one saidv arms having transverse corrugations or crimps, and an internal bead formed in said ring adapted toco-act with said corrugations to resiliently retain the ring in ad justed position.

In testimony whereof I atfix my signature in presence of two witnesses.
