CUE TIP.

Application filed March 20, 1925. Serial No. 16,998.

To all whom t may concern.

Be it known that I, VINCENT AJELLO, a citizen of the United States, and a resident of Pittsburgh, in the county of Allegheny' and State of Pennsylvania, `have invented a new and useful Improvement in Cue Tips; and I do hereby declare the following to be a full, clear, and exactV description thereof.

My invention relates to tips for billiard cues and the like and to the manner in which they are secured to the cue stick.

One object of my invention is to provide a cue tip that may be more readily applied to or removed from a cue than those heretofore employed.

Another object of my invention is to provide a tip construction embodying means for strengthening the end ofthe cue to which the tip is applied.

Still another object of my invention is to simplify and -improve generally cue tip structures.

One foim which my invention may take is shown in the accompanying drawing wherein Fig. 1 is a view showing a portion of a cue to which my invention is applied; Fig. 2 is a longitudinalsectional view'of a portion of the structure of Fig. 1; Fig. 3 is a similar view but showing the position assumed by certain of the parts during the act of removing from or aiiixing a tip to the cue; 4 is a detail view showing one of the parts `entering into the structure of Fig. 2; Fig. 5 is a view looking in the direction of the arrows, on the line 5-5 of Fig. 3; Fig. 6 is a view taken on the line 5-5 but looking in the opposite direction and Fig. 7 is a detail view of another one of the parts entering into the structure of Fig. 2.

In practicing my invention I may provide a cue stick 7 of usual form that is of reduced diameter at its upper end, for the reception of a ferrule or sleeve8 of ivory or similar material, to support and strengthen the outer end of the member 7. The stick 7 is cored on its longitudinal axis for a distance sufficient to receive a metal block 9 that may be driven into position therein and which has a knurled portion 10 to prevent turning thereof in its seat and to assist rin preventing its accidental withdrawal from the stick 7. A plug 11 is provided for closing the lower end of the tubular portion of the block 9, such plug having a drive fit with said block. The plug is provided with a socket or recess into which the lower flattened end of a threaded rod 12 loosely seats, so as to have longitudinal but non-rotative-movement with respect to the plug 11.

v A spring 13 surrounds the rod 12 and is held between the shoulder 12a of the rod and a shoulder 14 in the block 9. In assembling the parts just referred to the spring is first placed upon the rod 12, the lower end of the rod is slipped into the plug 11, and then the whole inserted into the tubular portion of the block 9, the plug 11 having a drive lit with the block so as to be held against movement therein. The block 9 and its contained parts are then driven into the end of the stick 7.

The tip proper consists of leather or simiing the tip 15 to its base 16 a tubular pin 17 y is inserted through the opening at the center of the base 16. This member 17 has a head that may be of ang'jularr form to hold it against rotative movement or may be held against such movement by the glue or cement that is employed for attaching the member 15 to the member 16. The member 17 is screw threaded on its interior wall so that it may be attached to the upper screw threaded end of the rod 12.

The block 9 is provided upon its upper enlarged end with a pair of teeth 18 that are adapted to sink into the libre base washer 16 when the parts are in the position shown in Figs. 1 and 2, to prevent rotative movement of the tip 15 with respect to the stick 7.

In order to apply the tip 15 to the stick, it is first brought to the position shown in Fig. 3 and rotative movement imparted thereto to start the threaded member 17 upon the threads of the rod 12. An outward pull is then exerted on the tip 15 to move the rod 12 upwardly against the pressure of the spring y13 so that the tip andits seating washer 16 may be rotated without interference from the teeth 18 until it has been screwed in such distance that it will seat against the outer end of the ferrule 8. Upon release of the tip 15 the spring 13 will draw it inward so that the teeth 18 may be imbedded in the libre washer 16. The tip is thus firmly held against rotative movement.

When it is desired to replace a worn tip by a new tip, the old tip is grasped between the lingers and pulled outwardly so as to compress the spring and permit the washer to clear the teeth i8. ri`he tip then is rotated to unscrew it from the rod 12, and a new tip applied in the manner above described.

rhe block S) is ot' such length that it entends into the stick 'i' beyond the lower edge oi' the ierrule 8 and strengthens the stick. Considerable loss has heretofore resulted 'trom breakage oit the sticks at the point where the lower end ot the r'errules terminate. The metal member 9 prevents this loss and also provides a. firm seating surface tor the washer 16.

l therefore provide a cue structure that is much stronger and more serviceable than those heretofore employed, and one wherein tip renewals may be made with a minimum expenditure ot time, without in'ipairment oi its utility. The tip parts l5, l@ and 1'? are made into a unitary structure and these units will be sold to billiard room proprietors and the like so that the)7 can at all times keep their cues in good condition with a small expenditure oi' time and expense, since the cost of the units so constructed is small compared to the time lost in repairing cues by the old method wherein tie cues were out ol service during the period required 'tor the glue to dry. lt has heretofore been necessary 'for a billiard room proprietor to carry a large stock of cues on hand in order that he would have a suiiicient number in condition for service while others were being repaired.

l claim as my invention:

l. rlhe combination with a cue stick, of tip structure comprising a. threaded member secured to the stick, means for yieldably holding said member against longitudinal movement. a tip, and a threaded member secured to the tip and adapted to engage with the first-named threaded member.

2. rihe combina-tion with a cue stick, ot tip structure comprising a threaded member secured to the stick, a tip, a threaded inember secured to the tip and adapted to engage with the first-named threaded member, means for yieldably holding one oi' said threaded members against axial movement, and means for locking said tip and said stick against relative rotative movement.

3. 'Ehe combination with a cue stick, oi a centrally apertured metallic bushing secured to the outer end of said stick, a member disposed in said aperture and threaded at its outer end, means tor preventing rotative movement olif said threaded member within said aperture, means for yieldably holding said threaded member against axial movement, a tip, and aV screw threaded member carried by said tip for engagement with the iirst-named screw threaded member.

e. The combination with a cue stick, of a centrally apertured bushing having a reduced shank portion extending into said stick at the longitudinal axis thereoi and having a shouldered head portion seating against the outer end of said stick, a threaded member within said apertured bushing, means for preventing rotative movement oiz said threaded member, means for yieldably holding said threaded member against movenient in an axial direction, a. tip, a screw threaded member carried by said tip for engagement with the first-named screw threaded member, and toothed projections upon the outer en d of said bushing to prevent rotative movement of the tip when said tip is in operative position.

In testimony whereof I, the said VINCENT AJnLLo have hereunto set my hand.

VINCENT AJ ELLO.
