COMPLETE SPECIFICATION.
Improved Fastening for Leather or Rubber Tips on
Billiard Cues.
I, ERICH LUDWIG MARUGG, a citizen of Switzerland, and resident of
Auerbach in the Vogtland, Kingdom of Saxony German Empire Merchant
do hereby declare the nature of my invention and in what manner the same is
performed to be particularly described and ascertained in and by the following
statement :-
The object of the present invention is to provide a device for affixing the
rubber or leather tips to billiard cues in such manner that the same may be easily
and conveniently detached when worn, whilst at the same time an unintentional
detachment of the same, and the inconvenience caused by having to mend the cues
are effectually avoided.
The device consists of a cap attached to the end of the cue and having a lower
external thread onto which a sleeve is screwed, said sleeve carrying in its upward
end the rubber, leather or combined rubber and leather tip.
The cap is further provided with a spring pin adapted to engage in a suitable
orifice in the sleeve when the latter has been screwed into position and thus securely
lock the same.
And in order to render my present Specification more easily intelligible, reference
is had to the accompanying drawing in which similar letters denote similar parts
throughout the several views;
Fig. 1 being a vertical section at the top of a cue with the sleeve removed.
Fig. 2 a similar section of the sleeve and tip.
Fig. 2 a part section of the sleeve, with a modified form of tip and
Fig. 3 a vertical section showing cap and sleeve in position on the cue, with the
locking pin about to engage in the orifice of the sleeve.
The cap or ferrule is fitted to the top a of the cue, and provided with an
internal spring c soldered or otherwise attached to it, said spring e carrying at its
upper end a piu projecting through the cap (Fig. 1). The cap has further a lower
external thread onto which the internal thread of the sleeve d is screwed. The
sleeve d has an upper internal thread cut in the opposite direction to and
serving for the reception of the rubber or leather tipe which is hollowed out at its
lower end, said sleeve has further an internal circular groove d¹ below the
upper thread 2 and also an orifice c¹ in its side, into which the pin of the spring c
engages.
In order to affix the tip to the cue the sleeve d is passed over the cap b, the
spring c being pressed back into a groove cut in the top of the cue (Fig. 1); the
said sleeve is then screwed tightly down onto the cap & so that the lower surface
of the rubber or leather tip is compressed and flattened into the circular groove d',
when this has taken place the pin of the spring e will engage in the orifice c' of the
sleeve d, which has come into position before it, and thus the parts are locked
firmly into position.
The tips may be entirely of leather (Fig. 2) or of leather and rubber (Fig. 2^)
or entirely of rubber (Fig. 3).
In the first case the lower part e¹ of the tip should be of a somewhat softer
nature to allow of its being compressed into the groove d'. If leather tips are
employed the same may be held in position in the sleeve by means of screws fƒ
(Fig. 2) inserted through the sleeve and penetrating the leather. It is obvious
that on screwing the sleeve onto the cue the tip on contacting with the top of the

page_text: cap will not tend to loosen, since the threads and 2 are right and left handed..
Rubber tips are advantageous, since they require no chalking.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :
1. The combination of a cap affixed to the end of the cue, said cap being pro-
vided with external thread and internal spring e with projecting pin, a sleeve d
having lower internal thread to engage the thread of cap and upper internal
reverse thread a tip e secured in said upper thread and orifice in the side of said
sleeve substantially as described.
2. The combination of a cap affixed to the end of the cue, said cap being pro-
vided with external thread and internal spring c with projecting pin, a sleeve d
having lower internal thread to engage the thread of and
cap
internal reverse
thread and circular internal groove below same, a rubber tip e secured in said
upper thread and orifice for the purpose substantially as described.
