FASTENER FOR THE TIPS OF BILLIARD-CUES.

Specification of Letters Patent.

Patented Dec. 14, 1920.

To all whom it may concern:

Be it known that we, WILLIAM FEHLI-IABER and CHARLES L. SMITH, citizens of the United States, residing at Highlands, in the county of'Monmouth and State of New J ersey, have invented new and useful Improveinents in Fasteners for the Tips of Billiard-' Cues, of which the following is a specification.

This invention relates to an improved fastener for the tips of billiard cues.

The principal objects in view are to provide for fastening the tip Without the use of glue and in such manner that there is no weakening of the cue, that the tlp 18 held with the utmost security and rigidity and is not susceptible to any loose play, and that the tip may be readily and quickly apphed to or removed from the cue.

With the above objects in view, the invention consists of certain novel features of structure and combination which will be set forth at length as the description proceeds.

An embodiment of the invention is illustrated in. the accompanying drawings wherein:

Figure 1 is an elevation of a one having a tip secured thereto by the fastening means of the present invention.

Fig. 2 is a central vertical sectional view, the tip being shown in elevation.

Fig. 3 is a similar view in a plane at right angles to the plane of Fig. 2.

Fig. 4 is a detail sectional vlew on the line 4l of Fig. 3.

Figs. 5 and 6 are detail horizontal sectional views on the lines 5-5 and 6--6 of Fig. 3 looking in the direction of the arrows.

Figs. 7 and 8 are detail perspective views of inclosed elements of the fastener.

Similar characters of reference designate corresponding parts throughout the several views.

The one A carries at its outer end a projerting ferrule 1 which is externally flush with said one and which is preferably formed with internal threads 2. These are essentially provided in connection with the securement of the tip B but are preferably also utilized for the attachment of the ferrule to the cue and are so shown. Accordingly, the threads 2 in the preferred construction are continued throughout the length of the ferrule and are engaged with a projecting tenon a at the end of the one A. In practice, the tenon a may be left smoothsurfaced and the ferrule '1 may be used by virtue of its threads 2 to cut the cooperating threads on said tenon. An external annular shoulder a at the. junction of the tenon a and the one body provides a bearing or seat for the adjacent end of the ferrule.

The tip B, which may be of any material having the desired cushioning properties, leather being the material most frequently employed, has a ball-engaging portion 5 located beyond the end of the ferrule and of the ordinary form. Said tip also has a reduced axial extension I) which is relatively hard; in the case of leather, the material of this extension may be treated in any suitable and known manner to secure the desired hardness. At the junction of the engaging portion 7) and the extension I) an annular shoulder b is provided which has a flat and uniform hearing or seating against the adjacent end of the ferrule. The extension 6 preferably has engagement with the threads 2 of the ferrule. Preferably, said extension is left smooth-surfaced and, as turned into the ferrule, threads are out thereon by the threads 2. In order to hold the tip B against accidental turning movement, one or more notches may be provided in the surfaces of the ferrule which are in contact with the tip. As shown and preferred, a notch 3 is out in the outer edge of the ferrule and an adjoining notch 4 is cut longitudinally in the threaded portion of the ferrule. These notches have substantially perpendicular walls which, considering the resilient nature of the material of the tip B,

function similarly to retaining pawls in.

holding said tip against accidental turning movement; however, said notches offer no appreciable resistance to the turning manipulation of the tip, when it is desired to remove the same from the ferrule.

The shoulder 55 and the threaded engagement of the extension I) assure of the rigidity of the tip with reference to the ferrule; and such rigidity is made permanent by the employment of fastening parts which act independently of the extension 5 in the retention of the ferrule and which also relieve i forms to the internal diameter of the ferrule. Its vertical end faces are provided with threads 7 for engagement with the threads 2 and its side faces 8 are preferably parallel. The arms 6 are associated with the block 5 to bind the tip thereto and in such way that they may be moved to provide for the disconnection of the block and the tip as occasion may require. In the construction preferred said arms are connected in pairs by a straight bow 8 which functions as a pivot bar and has a seating in a transverse recess 9 in the under face of the block 5. Two pairs of arms 6 so connected and associated with said block are provided for engagement with the tip at opposite sides thereof. At

.their terminals the arms 6 are provided with angular gripping portions 10 which engage in recesses 11 in the extension 6, these recesses being formed as radial and inward extensions of longitudinal recesses 12 cut into the surface of the extension I) for a depth suflicient to enable the arms 6 to be swung in clear of the threads 2. If desired, the walls of the grooves 9 may be upset to provide against the separation of the arms 6 and the block 5. The under face of the extension 1) preferably has a flat and uniform bearing against the upper face of the block 5, further insurance of the rigidity of the tip B relatively to the ferrule being thus provided.

The securement or removal of the tip may be effected readily and quickly.

The tip, prior to its attachment to the ferrule, is first connected to the block 5 by means of the arms 6. These arms which lie at the sides of the block 5 are swung relatively inward to engage their angular terminals 10 in the recesses 11 and so bind the tip in position upon the block. As thus connected together, the tip and the block form a unit which may be inserted into or removed from the ferrule by simply turning the tip in the appropriate direction to insure that the cooperating threads of the unit shall feed inward or outward relatively to the threads 2. In inserting the unit the tip is turned to feed the block 5 inward into the ferrule and to produce a like effect upon its extension I) until its shoulder b has relatively strong frictional contact with the adjacent end of the ferrule. At such. time, the notches 3 and 4 act in the manner described to prevent'the accidental turning movement of the tip in the reverse direction.

Having fully described our invention, we claim:

1. In a billiard cue tip-fastener, the combination of a ferrule projecting from the cue andhaving internal threads, a tip formed to have a bearing against the end of the ferlower and side faces of said block detacha- 3 My connecting said tip and said block to provide for their manipulation as a unit relatively to the ferrule.

2. In a billiard cue tip-fastener, the combination of a ferrule projecting from the one and having internal threads, a tip having a shoulder to bear against the end of the ferrule and also having an extension within the ferrule for engagement with said threads, a block having faces provided with threads for engagement with said internal threads and means partially surrounding said block and detachably connecting said tip and said block to provide for their manipulation as a unit relatively to the ferrule.

3. In a billiard cue tip-fastener, the combination of a ferrule projecting from the one and having internal threads, a tip formed to have a bearing against the end of the ferrule, a block having faces provided with threads for engagement with said internal threads, said tip having inwardly and radially directed recesses, and arms movably associated with said block and having angular terminal portions for gripping engagement in said recesses.

4;. In a billiard cue tip-fastener, the combination of a ferrule projecting from the one and having internal threads, a tip having a shoulder to bear against the end of the ferrule and also having an extension within the ferrule for engagement with said threads, said extension having recesses in its engaging surfaces which terminate at their upper ends in inward and radial extensions, a block having faces provided with threads for engagement with said internal threads, and arms movably associated with said block and having angular terminal portions for gripping engagement in the extensions in said recesses.

5. In a billiard cue tip-fastener, the com bination of a ferrule projecting from the cue and having internal threads, a tip formed to have a bearing against the end of the ferrule, a block having faces provided with threads for engagement with said internal threads, and arms connected in pairs by bows which form pivot bars and have transverse bearings in said block, said arms lying at the sides of said block and having inturned terminal extensions, said tip having recesses in which said extensions engage to connect said tip and said block.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
