ILLINOIS.

Specification of Letters Patent.

Patented July 7', 1908.

Application filed November 13, 1907. Serial No. 401,945.

To all whom it may concer/n:

Be it known that we, WALTER EMERY LANCASTER and THOMAS CHARLES NICHOLS, citizens of the United States, residents of Quincy, in the county of Adams and State of Illinois, have made aV certain new and useful Invention in Devices for Marking Tennis- Courts, &c., and declare the following to be a full, clear, and exact descri tion of the same, such as will enable others s rilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 is a perspective view of the invention. Fig. 2 is a vertical transverse sectional view taken through the center ofthe wheel with the lower' part of the spout broken away at one side to show the interior thereof.

The invention relates to rotary marking machines for tennis courts, and ball grounds,

land it has for its object the provision of irnproved means for feeding the' lime or marking powder in laying off such'grounds and cour s.

The invention consists in the novel construction and combinations of parts, as hereinafter set forth.

In the accompanying drawings, illustrating the invention, the letter a, designates a hollow marking wheel having a peripheral` surface provided with perforations as at 2, for the emission of the white powder.

l), is the hopper for supplying the marking powder to the wheel a, said hopper extending along the handle bar c, against which it normally rests, being connected thereto by means of a loop d. This hopper is designed to be of sufficient size to contain enou h powdered lime or the like to supply t e wheel a for a given time. with a tapered spout portion or extension e, having a lateral outward bend and terminating in a cylindrical head portion f, having a circular iiange g, which is designed to abut against a central opening h, of the lateral face c, of the wheel, through whicli a hollow thimble m, extends and is secured to the end of the spout within the head portion f. This thimble is provided with a circumferential flange/a, w ich abuts against the inside of the wheel face k. The margin of the opening h, bears between the flanges g, and n. The head j, is provided witha journal bear- It is ,provided ing p, at its end for the reception of the end bar a circular plate collar fu., which fits neatly but freely wit 1in the thimble m, closing the outer portion of the same and forming a guard to prevent the escape of owder between the head and thimble. T ie flange n, of the thimble forms' a guide over which the powder feeds into the wheel, and guards against its escape through the opening h, of the wheel face.

The wheel and hopper are usually Secured together, a wooden handle bar c, being passed through the loop d, of the hopper into the socket s, of a forked spring head t, which is provided with branches o, the ends lw, of which form bearings for the ends of the transverse journal rod.

Although the hopper extension is laterally bent to extend around from the central line of the handle bar to the side of the wheel, its

lbottom is straight, so that it will be in line with the handle bar c, and will provide an even surface for the passage of the powder from the hop er. The powder passing into the hollow w eel falls over the flange n, of the thimble against the transverse rod y', and downward to the bottom of the wheel, where it passes through the circumferential perforations in such wise as to make a broad mark on the ground. l

Having described the invention, what we claim and desire to secure by Letters Patent 1s:

1. In a rotary marking machine, the combination with a hollow peripherally perforated wheel and its laterally attached hopper, of a handle bar, and a forked spring socket head for said handle bar.

2. In a rotary marking machine, a hollow peripherally perforated wheel, having a transverse journal rod connected to one of its lateral faces, and a central opening in the opposite lateral face, a hopper having a lateral flanged extension communicating with said central opening, and carrying an inside flanged thimble, and a guard collar secured to said transverse journal rod.

3. In a rotary marking machine, a hollow peripherally erforated wheel having a transverse journalprod and a central opening in its lateral face, and in communication therewith a lateral hopper extension having a journal bearing head.

In testimony whereof' We aflix our signatures7 1n presence of tWo Witnesses.

W. EMERY LANCASTER.

4. In a rotary marking machine, a hollow peripherally perforated Wheel having a cenl i 5 tral opening7 and a lateral hopper having a l T' CHARLES NICHOLS' hollow langed end portion engaging said central opening and communicating With the interior of the Wheel.
