Applicatimtfiled November 20, 1916. Serial No. 1325209.

To all whom it may concern:

Be it known that I, J AMES H. HALL, a citizen of the United States, residing at Lexington, in the county of Lafayette and State of Missouri, have invented certain new. and useful Improvements in Chalking-Machiues, of which the. following is a specification.

My invention relates to a chalking machine to cooperate with articles like; billiard cues and I particularly aim to provide an article of this class which may be constantly or power driven. The use of thismachine enables thebilliard or other player to dispense with handling the chalk so-that: there is slight danger of the. challcbeing trans ferred to his clothing, soiling it. or presenting an untidy appearance, and also so that the chalking operation may be. effected. rapidly and as well without the trouble in cidental to chalking cues in the usual manner.

One specific object of the invention is to provide a chalk holder for connection to an engine shaft for rotation therewith, in combination with a guide device to deflect the one tip to the center of the chalk held by the holder, and to provide the guide as a substantially horn-shaped member having a laterally extending wall through which fastening means may be passed to facilitate fastening of the horn to the casing.

With the above and additional objects, such as will hereinafter appear, in view, the invention has been embodied in one preferred form as illustrated in accompanying drawings, wherein Figure 1 is a longitudinal sectional view taken centrally through my improved ma chine, but showing the motor in side elevation, and

Fig. 2 is a front end elevation of the machine.

Referring specifically to the drawings, a suitable casing may be used and for instance the hollow substantially rectangular casing as shown in Fig. 1 of the drawings. This casing comprises a bottom wall 8, slde walls 4:, and end walls 5 and a top wall 6. Within the casing a suitable motor is disposed and it may be an electric motor as shown at 7 and which is fastened as by screws 8 to the Wall 3. When the motor used is an electric motor, the feed wires which are shown at 9, are passed through an insulatlng guide 10 secured to the top wall 6. The main shaft of the engine 7 is designated 11.

"Specification of Letters @Patent. Pat gmtefl July 1918,,

. Onthesaid shaft 11, I rigidly mount a suitable holder for chalk; which may be in the forniof a cylindrical block 12liaving a depression 13 atone end. The holder has a shank 14 directly secured to shaft 11 and said shankextends from a plate lofroni which extends at right angles claspingor gripping fingers 16. While any of the number of fingers may be provided, yet I preferably use four. The fingers may be of any, suitable shape, for instancecorrugated as shown in Fig. 1. Also thesefingers are of spring metal andhave a tendency to grip the chalk rather than to yield or move from Y the chalk. a y a Atv il7 I show; a substantially conical shaped horn which is open at the frustum and fronrwhich at the plane of the frustum,

a short cylindrical wall 18 extends inwardly and which partly houses the chalk and lingers 16. At the base of the horn, a flat laterally extending wall 19 is provided and through this wall fastening means for instance screws 20, may be passed so as to engage the preferred walls 3, 4: or 6.

The operation of the motor is controlled as usual by a suitable switch but before the motor is set in motion, a chalk block like 12 is inserted intermediate the fingers 16. These fingers effectively grip the chalk and hold it so that it turns with the shaft 11 and with the holder. Thus when the one tip enters the horn 17, the inclined wall thereof will guide the tip into the socket or depression 13 of the chalk and since the chalk revolves, the tip will be effectively chalked. Wall 18 will catch chalk which is loosened. from the block and not retained by the cue tip and since the motor 7 in operation causes an eduction of air, such chalk will be expelled from the machine, falling through the horn 17. As a result, the chalk will not enter the machine and interfere with the operation of the motor.

Since merely the preferred embodiment of the invention has been illustrated and described, it is to be understood that changes in the details of construction may be re sorted to within its spirit and scope.

I claim:

1. In a chalking machine, comprising aso that the tuhe will catch loosenedchalk and the tube being disposed in the path of educed air from the means to ope'rztte" the" holderto expel chalk therefrom.

2. In a chalking device comprising a said tube being in the path" of edil ced? air from the motor to expel chalk froin the machine. i' r a 3. In a chalking device comprising a casing; a sourceofp'ower within said casing and having" power" shaft: extending there from; ineansmounted onsaid shaft seeing as a base support for thejchalk; corrugated fingers attachedto said means and adapted to grip the chalk, and guide nieansflfor cues extending within the casing'and attached to one end thereof, said means having a laterally extending tube within which said chalk gripping means eiit'end so that the tube will catch loosened chalk, and the tube being disposed in the path of educed air from the 7 source of power to expel chalk therefrom.

pression and into which saidchalkin means extend so that the tube will catch loosened chalk, and the tube being disposed in the path of educed air fron'i' the source of power to'ex'p'el chalk therefrom.
