I, COLIN SALMOND, of 437 Geary Street, San Francisco, California, U.S.A.
Ship's Captain, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement:-
This invention relates to improvements in billiard cue chalkers, and consists in
the novel construction and arrangement of the parts hereinafter set forth and
claimed.
The object for the accomplishment of which this invention is designed is the
mechanical and even operation and application of the chalk to the cue, substantially
as is now accomplished by hand.
In the drawings:-
Fig. 1, is a longitudinal sectional view of the invention, the chalk holder and
spiral being shown in full lines;
Fig. 2, is an underside plan view of the invention.
For the purposes of description of the invention, with reference to the drawings,
we will let the letter, A, represent the chalk receptacle. As shown in Fig. 1, this
receptacle, A, is made square, and provided with a circular base, A'. The chalk
receptacle, A, is mounted on the spirally threaded rod, B, which is provided with
the raised thread, B', and cap, B2, to which the receptacle, A, is attached rigidly.
The cylinder, C, is provided at the bottom with a threaded perforation, Ci, the
threads of which extend between the threads of the spiral, B. In some cases,
however, I substitute for the internal thread, of the perforation just described,
points which are provided with anti-friction rollers. In ordinary cases, however,
I find the thread to give the greatest satisfaction.
The spring, D, normally presses the base, A', and rod, B, outward, as shown in
Fig. 1, of the drawings. The outward throw of the rod is limited by the cap, E,
which is screwed ou the end of the cylinder, C. The cap, E, is provided with a
perforation, E', large enough to admit the end of a cue.
This cue chalker is designed to be mounted in the wall or floor of a room, in the
frame of a table, or to be suspended by a string. To secure the cylinders in place
I have provided the cylinder, C, with an annular flange C to receive screws, which
are screwed into the wall. When the device is used by hand these screws are
dispensed with.
In its operation this invention acts as follows: When it is desired to chalk the
tip of the cue it is inserted in the perforation, E¹, in the cap, E, and pressed against
the chalk held in the receptacle, A. The pressure on the cue causes the chalk to
recede against the expansion of the spring D. In thus receding, the spiral rod, B,
in passing through the perforation C provided for it is rotated, causing a rotary
motion to be imparted to the chalk, which spreads it evenly on the cue. As the
cue is withdrawn the spring causes the spiral and chalk to follow, the reverse
rotary movement being imparted.
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
consider novel and desire to claim is :-
1. In a billiard cue chalker, the combination of a chalk holder, A, mounted

page_text: loosely in a cylinder, C,. or its equivalent, with a spring to, maintain the chalk
holder extended, and a device, B, to rotate the chalk holder as it is receded,
substantially as described.
2. In a billiard cue chalker, the combination of a chalk holder, A, mounted
loosely in a cylinder, C, or its equivalent, with a spring, D, to maintain the chalk
holder extended, a rod, B, attached to said chalk holder and provided with a spiral
thread, and engaging devices to rest in the thread of the rod and cause it to rotate
when receded or extended, substantially as described.
Dated this 5th day of October 1896.
