T0 AEL WHOM IT MAY CONCERN:

Be it known that I, JOHN W. CARTER, of the city, county, and State of New York, have invented, made, and applied to use @new and useful Chalk-Marker for carpenters, stone-cutters, and others; and I do declare the following to bea full, clear, and correct description of my said invention, reference being had to the yaccompanying drawings, making part of this specification, and to the letters of reference marked thereon, in

Which- Figure 1, a. front view of my invention` Figure 2, a sectional view of a part of the same.

Figure 3, a view of the same showing the parts separately.

In the drawings like parts of the invention are pointed out by the same letters of reference.

The nature of the present invention consists in `the constructionV and operation, as more fully hereinafter described, of a new and useful article for the use of carpenters, stone-cutters, and others, which I term a chalk-marker.

Heretofore the carpenter, stone-cutter, or other artisan, has made use of a stringl or cord which was chalked by hand and placed upon the board, stone, or other article upon which the markwas to be impressed, in order that the same might answer as a guide to saw or cult by. The string was then held rather tightly at each end and snapped so as to impress upon the board or stone a mark to serve as a guide to saw or out by.

To enable those skilled in the art to make and use myffinvention, I will proceed to describe the same.

A shows a receptacle for the chalk or other marking material employed. This receptacle `may be made circular or of any convenient shape, and may be made of two pieces, as clearly shown in iig. Soi' the drawings. B is a spindle or shaft inserted within the receptacle A through suitable openings, and C is the cord which is Wound upon the spindle or shaft, one end of the same projecting through the opening a in the receptacle. This spindle may be provided with a spool upon -yvhich the cord may be Wound when desired. v

The receptacle A may be filled with chalk or other marking material, and the cord isv drawn from the same by taking hold of the end projecting through the opening in the receptacle. As the cord is drawn therefrom it is chalked by coming into contact with the chalk or'other material placed in the receptacle. When drawn out the operation is precisely the same as now pursued with the ordinary chalked cord in use. After use, the cord may be rewound by turning the spindle by means of a crank upon the same, or the spindle may be revolved iu any convenient Way.

My invention is particularly valuable, owing to its cheapness and the rapidity with which vthe Work cau be done. i

Having thus described the' same, what I claim as new, and desire to secure by Letters Patent, is

In combination With'the chalk-receptacle, I claim the use or employment ofthe spindle and cord, when'the same shall be constructed and combined substantially as shown for the purpose indicated.

JOHN W. CARTER.
