SPECIFICATION forming part of Design No. 27,673, dated. September 21, 1897.
Application filed August 3, 1897. Serial No. 646,982. Term of patent 14 years.
To a]! u'imm if may concern:
lie it known that I, 'Inonas I. GnEoEE, a citizen of the United States, residing at the city oi Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented and produced a new and original Design for Manhole-Covers, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.
Figure 1 is a top or plan view of a manholeeover, showing my design; and Fig. 2 is a central vertical sectional view of the same.
The leading feature of my design consists in the raised riblike projections, whieh,when viewed in plan, as in Fig. ],are arranged e11- tirely within a circular or substantially circular outline in two series crossing each other at right angles to form the appearance of a checker-board, and which when viewed in section, as in Fig. 2, appear to project upward from a concaved base.
Referring to the drawings, A is the base of the manhole-cover, which in outline is substantially circular and in vertical section is checker-board included within the outline of 35 said field, within which asphaltum, granolithic, or other matter is introduced and packed therein.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
The design for a manhole-cover, substantially as shown and described.
In testimony whereof I have hereunto set my signature in the presence of two subset-ii ing witnesses.
