Application September 24, 1934, Serial No. 745,324 Renewed March 12, 1936 1 Claim. (01. 53-3) This invention relates to a novel accessory in the form of an attachment cooperable with the lid and glass top of a percolator and expressly designed to serve as a means for maintaining 5 said glass top against accidental displacement. By way of introduction it is to be pointed out that in the majority of constructions the cap like glass top of a percolator is generally pro vided with a rim having diametrically opposed 10 projections which serve to hold the glass top in place after it is inserted in lid and turned slight ly. In most instances the lid is formed With a central opening having a depending annular ?ange equipped with diametrically opposite 15 clearance notches to accommodate the projec tions whereby to permit the projections to be held in place by the ?ange. It is a matter of common knowledge, however, that wear and tear of these parts soon permits rotary shifting of 20 the glass top and it is frequently displaced, re sulting in breakage and other damage. The purpose of the present invention is to provide a resilient wire device in the nature of a clip which can be attached to the button-like 25 projections on the glass top and which coop erates with the ?ange in a more satisfactory manner to satisfactorily hold the glass top in place and against accidental displacement. Other features and advantages will become more readily apparent from the following de scription and drawings. In the drawings:— Figure 1 is an elevational view of the wire re taining device or clip showing the manner in 35 which it is associated with the glass top and hinged lid of a percolator. Figure 2 is a bottom plan view of the struc tural assemblage depicted in Figure 1, the sec tion being on the plane of the line 2—-2 of Fig ure 1. Figure 3 is a vertical sectional view taken ap proximately on the plane of the line '3——3 of Figure 1. Figure 4 is a section on the vertical line 4—4 45 of Figure 1. Figure 5 is a perspective view of the wire from which the retaining clip is bent or fashioned. Figure 6 is a perspective view of the retainer or clip per se. Referring now to the drawings by distinguish ing reference characters I call attention ?rst to Figure 1 wherein the percolator is denoted by the numeral 1 and the hinged lid is indicated at 8. The glass top, which is conventional, is de 55 noted by the numeral 9. The customary rim 50 ID at the bottom of this glass top is formed with the usual diametrically opposed button-like pro jections H. Under ordinary circumstances these are adapted to be placed through the clear ance notches I2 formed at diametrically oppo site points in the depending circular ?ange I3 carried by the lid. That is to say, the rim [0 ?ts telescopically down through the opening and against the ?ange, the projections of keepers ll being placed through the notches I2 and then turned so as to be held against the lower edge of the ?ange. As before stated, however, these parts frequently become loose and this results in a recurring displacement of the glass top. Therefore, I have evolved and produced requi 15 site simple and economical means to guard against such accidental displacement of the glass top. This means may be described broad ly as a retainer and it is in the form of a resili ent Wire clip M of the type shown in Figure 6. This clip may be formed from a single length of wire l5 (see Figure 5). It is bent between its ends to form a coil spring as at I6 and to further provide a pair of duplicate adapter 0 arms or branches I'I. These terminate in up bent eyes l8 which are adapted to snap over the projections H (see Figure 4) so that the eyes themselves will serve as retaining elements and engage beneath the edges of the ?ange as shown in Figure 4 to prevent displacement of the glass top. It is obvious that the wire must be non-corrosive and su?iciently resilient to en able it to be conveniently snapped into place and con?ned primarily within the limitsof the glass top itself. It is evident from the foregoing description that the novelty and invention resides only in the attachment or retaining clip illustrated in Figure 6. 35 Fundamentally this comprises retaining ele ments l8 to resiliently snap on and surround the 40 stock lugs on the glass top whereby to- permit these pieces l8 to serve as check elements or stops for holding the glass top- in place. Stated otherwise the principal novelty is in the features l8 with some means for attaching them together resiliently and holding them on the lugs so that they merely enlarge the lugs and provide a more satisfactory means of avoiding displacement of the glass top if and when the lugs or ?ange are spread or become worn. Thus it will be seen 50 that novelty resides in these stop- elements I8 which embrace the lugs and which are attached together through the instrumentality of resilient arms I‘! forming a connective element and which 55' 2 2,057,155 arms themselves are preferably associated with a spring or coil I6. tion claimed may be resorted to in actual prac tice, if desired. In practice the device is simply snapped on to the lugs after the glass cap is in place and this What is claimed is:— As a new article of manufacture, a retaining is done by swinging the lid 8 to open position. It is thought that persons skilled in the art to which the invention relates will be able to obtain clip'for a percolator top comprising a length of wire provided at opposite ends with loops fash ioned to embrace existing lugs on the percolator a clear understanding of the invention after con top, said wire being bent between its ends to de?ne a centrally disposed coil spring with later ally extending overlapping arm portions nor mally urged by said coil spring in a downward sidering the description in connection with the drawings. Therefore, a more lengthy descrip tion is regarded as unnecessary. Minor changes in shape, size, and rearrange ment of details coming within the ?eld of inven direction. FRED LUNDGREN.
