My present invention relates to tops for percolators and more especially to means for preventing same from accidentally'dropplng out of the percolator cover and either becoming broken, themselves or breaking some other dish. Among the objects of the invention are to provide 'a percolator top with means which will prevent the top from be coming accidentally detached from the per colator cover and dropping without'w'arning to the person using same; to provide a device of the kind indicated in which is provided means such that the top may become partially detached from the cover without being able to drop when the percolator is tilted into posit-ion to discharge the contents thereof; to provide means whereby the opening 1n a percolator cover may be expanded slightly so as to permit the insertion of the pereolator top withoutsaid top being unduly tight in the cover; and such further objects, advantages and capabilities as will hereafter appear and as are inherent in the construction disclosed. 7

In the drawing annexed hereto and forming a part hereof, Fig. 1 shows in elevation a per-colator top embodying my invention and,

in dotted outline the cover with which the top is used; Fig. 2 shows a bottom plan view of the structure shown in Fig. 1 Fig. 3 is a horizontal section substantially along the plane indicated by the line 3-3, Fig. 1.

Referring more in detail to the annexed drawing, numeral 1 designates the customary cover for a. percolator which has a generally centrally arranged opening provided with an inwardly turned flange 2. This flange is provided with indentations forming grooves 3 for the reception of the projections t and 5 upon the flange 6 of the top 7 This top is provided with a suitable ridge 8 around the periphery thereof to rest upon the cover and prevent the top from sliding into the cover farther than the predetermined distance.

The top is provided with a knob 9 whereby it may be grasped and turned or lifted. Such tops are customarily hollow as shown by dotted lines in Fig. 1. .Projections 10 are formed upon the top, preferably by cutting away a portion of the shoulder to form somewhat rounded parts as'indicated in cross section in idig. 3. The purpose of these lugs or projections 10 is to enable the user to expand the opening surrounded by the flange 2 if the same should be alittle too small,- thus tending percolator top, which is customarily made of glass. It will be understood that by inverting the top, holding itby the flange 6, insert ing the small end of thetop through the open ing in the flange 2 and then simultaneously pushing and turning, the lugs '10 can be caused to expand the opening slightly, thus making it 'possible'to easily insert the flange 6 through the opening.

However, after the lugs 4 have passed through the grooves 3 in the flange, the lugs to bind and possibly crack the flange 6 of'the out. However, in course of use, the top often gets turned until the lugs come into alignment with the grooves. When this takes place, the top may drop out of the cover and fall upon a cup or other dish and cause breaking thereof or of the top. Also, in the handling of the percolator, when empty, the top may become detached and fallupon the floor, thus being broken. With this construction, however, the user will have a warning that there is danger of the top becoming detached and falling,'for the reason that when the lugs 5 pass through the grooves 8, the lugs {i will engage the flange 2 and thereby prevent the top from falling. The top will project an undue amount from the cover, thus giving the user the necessary warning. top can then be pushed back into place and rotated until the lugs 5 will prevent thetop from becoming detached or partially detached from the cover. I I

While I have disclosed this invention as used in connection with percolators, it is possible that it may have other uses and I therefore do not wish to be limited to the use stated.

Also, theproportion and arrangement of parts may be varied within certain limits without departing-from the spirit of this invention. For instance, the lugs 41- and 5 may be spaced laterally farther apart and the distance of these from each other, longitudinally of the flange 6, will depend upon the width ofthe flange 2, it being necessary that there be sufiic-ient space between the lugs The peroolator I 4t and 5, longitudinally of the flange, to perlnit the flange 2 to pass between these two lu s. flaving now described my invention, I claim:

1. A percolator top having a flange for insertion into a percolator cover, said flange having holding lugs on its exterlor surface,

' and said lugs being spaced longitudinally and transversely of the flange.

2. A percolator top having a flange for 'insertion into a percolator cover, said flange having pairs of holding lugs on its exterior surface to cooperate with a flange of the curing lugs on the exterior surface of the flange, said lugs being so arranged that the top may be inserted into the cover part Way and must then be turned part of a revolution before it can be inserted the remainder of the Way.

4. A percolator top having an external cylindrical surface and a plurality of pro jections adjacent said surface Which may be caused to engage the Wall of an opening with Which the top is to cooperate and thus cause enlargement of the opening.

5. A percolator cover having 'a'substantially central opening therein, in combination With a top to fill said opening, said top having projections adjacent av cylindrical Wall of the top, said projections being adapted to be forced to turn With the top in the opening to thereby enlarge said opening.

In Witness whereof, I hereunto subscribe my name to this specification.
