CHARLES F. SMITH, OF NEW BRITAIN, CONNECTICUT, ASSIGNOR TO LANDERS, FRARY & CLARK, OF NEW BRITAIN, CONNECTICUT, A CORPORATION.

PERCOLATOR-COVER.

Specification of Letters Patent.

Patented Jan. 3, 1911.

Application filed July 7, 1910. Serial No. 570,739.

To all whom it may concern:

Be it known that I, CHARLES F. SMITH, a citizen of the United States,residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Percolator-Covers, of which the following is a specification.

My invention relates to improvements in percolator covers and the objects of my invention are simplicity and economy in construction and efficiency of the article, particularly with reference to a durable transparent cover.

In the accompanying drawings :Figure 1 is a plan view of my percolator cover. Fig.

2 is a sectional view of the same on the line as w of Fig. 1. Fig. 3 is a plan view of my percolator cover on a smaller scale and in a modified form.

While the cover herein shown and de scribed is specially designed for use as a percolator cover, it is evident that it may be used as the cover for any other article that it is adapted for.

The cover comprises a metal frame or support and a glass or transparent dome mounted on thesaid frame.

A designates the metal frame the base of which is provided with a rim 4: and flange 5 designed to fit the top of a percolator. Extending upwardly from the rim 4 there are three arms 6, which curve upward and inward toward the center where they are united in a centrally perforated dome-holding disk 7 that is preferably made in one piece of metal with the rest of the frame A. The several arms are provided with longitudinally extended hollow ribs or beads 8.

B designates a dome, of glass or equivalent transparent material, which is preferably made rather thin for glass and is provided with a bottom rim 9 that is designed to extend under the inner edge of the base rim 4 at the openings between the arms 6. The upper part of the dome is provided with a hollow boss or projection 10 that is designed to be received by the dome-holding disk on its underside. A cupped washer 11 is placed in the center of the dome on the inside where it and the dome are secured in place by a screw 12 that passes up through the said washer and the dome-holding disk into a threaded hole in the knob 13, which knob may be of any suitable material, preferably non-metallic.

The same general construction is shown in Fig. 3, only the frame A is provided with but two arms 6 instead of three, the said two arms being united at the center by the dome-holding disk 7, all the other parts Y being the same as herein first described and designated by the same reference characters.

As described it is evident that the arms 6 and 6 constitute means for supporting the dome holding disk upon the rim of the frame.

It is apparent that some changes from the specific construction herein disclosed may be made and therefore I do not wish to be understood as limiting myself to the precise form of construction shown and described, but desire the liberty to make such changes, in working my invention, as may fairly come within the spirit and scope of the same.

By my invention the liquid that is forced up by the percolator fountain may be readily seen through the dome and its operation watched substantially the same as if the cover were formed wholly of glass. The glass or transparent dome has its central portion connected with the central domesupporting disk and the weight of the said dome is transmitted through the said central portion to the said disk, then to the arms, and then to the base rim. The base, which is the largest part of the dome, is entirely free from all other parts of the frame, is never seated upon any object and need not have contact in any way with any other thing. The glass dome may be thin as compared with a cover wholly of glass whereby the complete cover is or may be lighter than an ordinary glass cover. The dome may be made comparatively thin instead of thick and heavy, because the frame protects it against breakage by concussion and by being thin it is less liable to break by reason of unequal expansion when rapidly heated.

The complete cover presents a neat and attractive appearance and the knob may be of a non-conducting material so that it will never be inconvcniently hot.

The article can be produced at a small cost and is very efiicient and durable.

I claim as my invention:

1. A percolator cover comprising a metal frame having a base rim, a dome-holding disk at its center, and means for supporting said disk on said rim a transparent dome having its central portion connected With the said disk, and means for holding the said dome and disk together, whereby the Weight of the dome is transmitted through its central portion to the said disk and finally from the said disk to the base rim of the said frame.

2. A percolator cover comprising a metal frame having a base rim, a central domeholding disk, and means for supporting the said disk on the said rim, a transparent dome mounted on the innerside of the said frame, a knob at the center on the outer side of the said frame and means for holding the said dome and knob in place on the said frame.

3. A percolator cover comprising a metal frame having a base rim, a central domesupporting disk, and a plurality of arms, With open spaces between, by means of Which arms the said rim and disk are united, a transparent dome on the inner side of the said arms and means for holding the said "dome in place on the said frame.
