(Cl. 53-3) The invention relates to percolator covers pro vided with transparent tops for observing the action of the percolators, the objects being to‘ im prove the construction of such tops, and their U attachment to percolator covers, to the end that liquid will not splash between the tops and the walls of the top-receiving openings in the covers, and to the further end that the tops may be in serted through such openings from the insides 10 of the covers, and be securely attached to them. The invention is illustrated in the accompany ing drawing, of which Fig. 1 is a vertical central sectional view through the upper portion of a percolator and its cover; Fig. 2 a partial plan H 91 view of the percolator cover; Figs. 3, 4 and 5 vertical central sectional views through the cen tral portions of covers and tops attached to them, illustrating modi?cations of construction; and Fig. 6 a plan view of the modi?cation illustrated 20 in Fig. 4, showing the top as having been rotated axially to a different position than that shown in Fig. 4. In the attachment of a transparent top to a percolator cover, the usual practice is to insert 25 the top from above the cover through a top-re ceiving opening formed in it, the dome of the top being larger than the opening so that the top rests upon and is supported by the margin of the opening. Various means have been provided for 30 removably retaining tops in this position. Be cause the tops have been thus attached, their ‘ inner ends are necessarily of smaller diameters than the openings through which they are in serted. As a result of this, liquid projected up ' wardly against the tops and the central portions of the covers, sometimes objectionably splashes between the walls of the openings and the ex— terior of the tops. Also, because it has been nec essary to provide considerable space for so in serting tops, handles attached to covers and ex tending above the tops have necessarily been spaced substantial distances above the covers. In the practice of this invention, a percolator cover is provided in its central portion with an ' opening in which there is positioned an integral transparent top, preferably formed of pressed the top, and the wall of the cover opening through i which it extends, are provided with interengag ing elements which may be of various forms and constructions. Having reference to the embodiment of the in- 6 vention illustrated in Figs. 1 and 2, a percolator l of conventional form is provided with a cover having a central portion 2, and a skirt 3 ?tting within the walls of the percolator body. The central portion of the cover is provided with a 10 top-receiving opening ll, which, in this case, is bounded by a yieldable ?ange 5 turned down wardly from the metal of the cover. Within opening 4 there is a top having a dome 5 project ing above the plane of the opening, and a skirt 15 '|_ within the cover projecting outwardly beyond the wall of the opening to prevent liquid from splashing between the top and ?ange 5. In attaching the top to the cover, it is pressed outwardly from the interior of the cover, sprin- 20 ing ?ange 5 laterally to permit the dome of the top to pass beyond it. Below the dome B the top is provided with a reduced portion 8 in which ?ange 5 lies to yieldingly lock the top to the cover. Suitably attached to the cover there is 25 an arch-shaped handle 9, the inner edge of which is relatively close to the top and to the cover, the use of such a handle being made possible by the construction and manner of attachment of the top to the cover. " 30 The embodiment of the invention illustrated in Fig. 3 is the same as that shown in Figs. 1 and 2, with the exception that the top-engaging ?ange I ll of Fig. 3 is provided with'a plurality of notches H which divide the ?ange into a plurality of 35 yieldable tines, and accordingly facilitate the in sertion and removal of tops. . In the embodiment of the invention illustrated in ‘Figs. 4 and 6, a top I5 is provided with one or more lateral projections I6 which overlie the 40 margin of a ?ange l1 surrounding the top-receiv- ' ing opening. When pressing the top through the opening, its lateral projections l6 may them selves form grooves l8 in ?ange IT, or these grooves may be formed in the ?ange before the 45 top is inserted. After inserting the top, it is ro glass, having a dome projecting above the cover, tated axially to the position indicated in Fig. 6' and having a splash-de?ecting skirt below the in which'projections l6 overlie the ungrooved cover and projecting outwardlyvbeyond the wall portions on ?ange I1. In the embodiment of the invention illustrated 50 i of the top-receiving opening. By reasoniof this construction of- the top, it is inserted in the cover in Fig. 5, the interengaging elements for locking opening from the inside of the cover, thus mak . the top 20 to the central portion 2| of a cover ing it possible to attach a handle to the cover with are the margin of the top-receiving opening, and a small space between the top and the handle. a split ring 22, preferably formed of resilient 55 For ‘attaching the top to a cover, the exterior of metal, applied to a groove formed on the top ad- 55 2_ 2,110,974 jacent to the base of its dome, the outer portion of ring 22 resting upon the margin of the opening. In each embodiment of the invention the skirt of the top projects outwardly beyond the wall of the top-receiving opening of the cover, serving the double function of retaining the top in the cover when the latter is turned upside down, and of preventing liquid from splashing between the 2.
