CUE-TIP,

Specification of Letters latent.

Patented Apr. 6, 1915 Application filed August 8, 1 914. Serial No. 855,818.

T 0 all whom it may concern Be it known that I, EDWARD W. WOMAOK, citizen of the United States, residing at .Velch, in the county of McDowell and State of West Virginia, have invented certain new and useful Improvements in Cue- Tips, of which the following is a specification.

This invention relates to one tips, and one of the objects is to provide a tip which may be securely attached in a novel manner and so locked that the tip can not be removed without destroying the latter.

In the accompanying drawings forming part of this application, and in which like characters indicate corresponding parts, Figure 1 is a view chiefly in section showing the manner of connecting the tip. Fig. 2 is a section on line 2-2 of Fig. 1. Fig. 3 is a bottom plan view of the tip. Fig. 4: is a view partly in section of a modification.

The one to which my improved tip is attached, is designated by 10, the cue being provided at one end with a member 12 having an internal screw threaded portion 14. A tip of leather is shown at 15, and this tip engages the threads and is thereby firmly held in position so long as the tip is not turned or unscrewed.

In order to prevent accidental or intentional unscrewing of the tip, an especially effective locking device is employed. The under side of the tip is notched radially to form ratchet teeth 16 which are engaged by pawl 17 when the tip has been nearly screwed home. The pawl is normally pressed outwardly by a spring 18, the latter being inclosed in tubular portion 21.

The pawl may be pressed inwardly and then held out of contact with the teeth of the tip until the proper time by a small plate 9.2. The latter is pivoted at one end and arranged to be engaged by the teeth, for the purpose of turning the plate on its pivot and causing it to be thrown out of the path of the movement of the pawl.

Fig. 2 shows the relative position of the plate and the pawl, after the former has been thrown out of engagement by the rotary movement of the tip. In gradually screwing the tip downward, the friction on the upper surface of the plate will cause the latt r t mo e ufiiciently to o ide t free the pawl. The edges of the teeth of the leather tip will also engage the edge of the plate. When the teeth are fully engaged by the pawl, it is impossible to turn the tip in a reverse direction, thus making it impossible to substitute an inferior tip, and also preventing a tip from becoming loosened during use. If the tip is removed by force by turning it in the reverse direction, it will be cut and damaged by the pawl.

In the form shown in Fig. 1 the member 12 is engaged by the screw 16 which also extends into the end of the cue, the latter having a separate ferrule 19, if desired. In the form shown in Fig. 4% the tip 15 is connected as in Fig. 1 and a similar pawl is employed. Member 20 is however in one piece and is connected directly with the one 10.

What I claim is:

1. In a device of the class described, a member having an internal screw thread at one end, a tip threaded into said member, said tip being provided with engaging devices, and a spring-pressed pawl adapted to contact successively with said engaging devices upon rotation of the tip in one direction and prevent the tip from being unscrewed by a reverse movement.

2. In a device of the class described, a member having an internal screw thread at one end, a tip for insertion in said member, spring pressed means for engaging the inner end of the tip, and a device for holding said means out of engagement until released by the rotary movement of the tip.

3. In a device of the class described, a member having an internal screw thread at one end, a tip for insertion in said member, spring pressed means for engaging the inner end of the tip, and a pivoted device for holding said means out of engagement until released by the rotary movement of the tip.

4. In a device of the class described, a member having internal screw threads, a tip engaged by the threads, a series of teeth formed on the inner end of the tip, a spring pressed pawl for engaging the teeth, a pivoted plate arranged to swing over one end of the pawl prior to the insertion of the tip, said pawl being released by the movement of the plate when the latt r is engaged by the t th;
