ADOLPH JOHNSON, OF MONTCLAIR, NEW J TENNIS-COURT CORNER-MARKER.
Specification of- Letters Patent.
Patented Aug. 2'7, 1912.
Application filed December 29, 1911. Serial No. 668,524.
To all whom it may concern:
Be it known that I, Anonrn JOHNSON, a citizen of the United States of America, and a resident of Montclair, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Tennis-Court Corner-Markers, of which the following is a specification.
Tennis-courts .are customarily marked in a prescribed pattern with a deposit of lime in straight lines or bands and meeting at right angles. A common width for these lines is two inches. When the lines are first 'run a somewhat elaborate measurement and survey is required. the lines become efl'acedin course of time, it is necessary to re-mark them at intervals, and, as after stress of weather or at the beginning of a season the lines are more or less completely obliterated, it is particularly desirable that the locations of the points of meeting of the lines should be more permanently marked.
The object of this invention is to provide a suitable stake for such corner marking, whereby remeasurement and resurvey may be avoided.
In the accompanying sheet of drawings whichv forms a part of this application, Figure 1 is a perspective of a tennis-court corner-marker constructed in accordance with my invention. Fig. 2 shows a portion of a tennis-court with the marker-at the meeting point of two of the court lines. I
The marker as shown consists of a cast iron stake having a fiat square head a and a shank consisting of intersecting webs b b. The edges of the webs are serrated to increase their hold in the earth. The length of a side of the head is the same as the of uniform width width of the lines so that the edges of the head ma be used as guides for thelocations of the s1des of the limed lines. The head may be enameled white to harmonize with the lines andrender the marker more easy to find.
The marker is driven into the ground at the junction points of the lines, so that the head will be flush with the surface. An eye a is provided at one corner of the head for the connection thereto in any convenient manner, as through a nail d inserted in the eye, corner marker to another to serve as a guide for one side of the line when applyin the lime. The axis of the eye 'isin line wit the adjacent sides of the head. The eye is ref-- erably depressed below the top face 0 the head so that the nail may be left in the marker without the nail head projecting above the ground.
The usualtennis-court lay out. has fourteen corne1 's and junction points at which the markers are to be located.
What I claim as new, and desire to secure by Letters Patent of the United States, is:
1. A tennis-court cornenmarker consisting of a stake provided with a flat rectangular head. I
2. A tennis-court corner-marker consisting of a stake provided with a fiat rectangular head and an eye depressed below the top face at one corner of the head.
Signed by me at Montclair, N. J. this 28th day of December, 1911.
