Description

Patented July 2, 1940 UNITED STATES PATENT OFFICE CHALK HOLDER .1 Claim.

The present invention relates to new and useful improvements in chalk holders particularly for cue chalk and has for its primary object to provide, in a manner as hereinafter set forth, a

device of this character embodying a novel construction, combination and arrangement of parts through the medium of which a cue chalk may be suspended in any convenient location so that the same may be easily handled by the user, and when not in use will be held conveniently and out of the way of the player of a game of billiards or pool.

Other objects of the invention are to provide a chalk holder of the aforementioned character which will be comparatively simple in construction, strong, durable, highly eflicient and reliable in use, compact, light in weight, and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawing wherein like characters of reference designate corresponding parts throughout the 25 several views, and wherein:

Figure 1 is a vertical transverse sectional view of my invention.

Figure 2 is a side elevational view of the invention.

Figure 3 is a perspective view of the spring tube.

Figure 4 is a bottom plan view of the chalk clamp.

Referring now to the drawing in detail, it will be seen that the reference numeral 5 designates a length of tubing, constructed of metal or other suitable material, having screw threads 6 and 1 at its top and bottom end portions.

An internally threaded cap .8 is screwed onto the threaded top end portion of the tube 5 and is provided with an integral eye 9 on its top side from which the device is suspended. On the under side of the cap 8 and within the same there is provided an eye I0 from which is suspended a tension spring II. An internally threaded collar I2 is screwed onto the bottom end of the tube 5, and protects the same from damage.

The tension spring II is releasably secured at its upper end to the eye l0 while its lower end is releasably secured to the spring tube l3 and acts to retract the spring tube l3 when the same is.

extended from the tube 5 when the device is in use.

The top end portion of the spring tube I3 is open as at M to permit the same to come to rest against the cap 8 and thus avoid damage to the eye it] when tension on the spring H is relieved suddenly. An eye 55 is provided on the inner bottom end portion of the spring tube I 3 to which the tension spring H is secured, while an eye i6 is provided on the bottom end to which one end of a length of chain ll is suspended.

A chalk clamp I8 having clamping jaws I9 is secured to the other end of the chain l1 through the medium of an eye 20 which has a shank extending therefrom which extends through the clamp l8 and is riveted thereto as shown at 22.

A conventional one chalk 23 is frictionally held between the jaws l9 and may be easily removed when desired.

The operation of the device is thought to be manifest but may be briefly described as follows:

The device is suspended from a convenient support through the medium of the eye 9 with the chalk clamp [8 at such a level as to be conveniently within the reach of the pool player when chalking of the cue tip is desired. When chalking a cue the chalk clamp l3 and chalk 23 are pulled to a lower level thus exerting a tension on g the tension spring H which tension when released permits the spring to withdraw the chalk 23 to a higher level and clear of the users head.

Although I have shown and described herein a preferred embodiment of my invention, it isto be definitely understood that any change or changes may be made in the structure and arrangement of the parts of the invention as claimed.

What is claimed is:

A chalk holder of the class described comprising an elongated tube, a cap threaded to the upper end thereof, an upwardly extending suspension eye on the cap, a downwardly extending suspension eye carried by the cap and located within the tube, a coiled spring having one end connected with the last-mentioned eye, a small tube encircling the spring and having its upper end open to fit over the second mentioned eye and the lower end of the small tube being closed and having an upwardly extending member thereon for receiving the lower end of the spring, a chain connected with the lower end of the small tube and passing through the lower end of the first-mentioned tube and a chalk holder connected with the lower end of the chain.
