An Improved Device for Chalking Billiard-cues.
We, RICHARD NAUMANN, Agent, of 17 Uhland Strasse, and OTTO KUNZE,
Locksmith, of 8 Schlössergasse, both of Dresden, in the German Empire, 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:-
The subject of this invention is an improved device for chalking billiard-cues,
which is adapted to be secured to the wall, and to chalk the cue submitted to its
action, whilst the same is pressed into contact with it. Owing to the pressure of
the cue, part of the device is raised and at the same time, turned round, so that the
chalk, with which the side of that part is provided, is brought into position for
chalking the top portion or head of the cue at all points of its periphery.
The said invention will be clearly understood by reference to the accompanying
drawing, in which
Figure 1 is a longitudinal section, and
Figure 2a similar section, taken at an angle of 90 degrees to the first, of the
improved chalking device.
Figure 3 is a side elevation of the said device,
Figure 4 is a plan thereof,
Figure 5 is a partial front view thereof,
Figures 6, 7, and 8 are, respectively, a side view, a front view and a top view or
plan of the pin guided by a spiral spring and adapted, in conjunction with a finger
or tappet, to arrest or lock the mechanism.
Figures 9 and 10 are, respectively, a side elevation and a front elevation of a
piece inserted in the tube of the chalking device; and
Figures 11 and 12 are, respectively, a side elevation and a plan of the rack.
This billiard-cue chalking device consists of a metal tube or sleeve m over which
is fitted another sleeve or tube h, half as long as the first and perforated. This
sleeve is provided with a spiral slot or groove n, the convolutions of which have a
steep or rapid pitch. A pin or studs secured to the tube or sleeve m engages in,
or is guided by, this spiral groove, so that, when the said tube is raised, it is
thereby at the same time caused to turn, the shape and position of the spiral
groove n being such, that the said sleeve m may, in thus rising, perform a complete
revolution.
The perforated sleeve h is provided with projections a to facilitate its attachment
to the bracket or support g secured to the wall. In order to cause the said tube or
sleeve My after it has been forced upwards, to again descend, a spiral spring p is
interposed between the lower flanger of the said sleeve m and the sleeve or
tube h.

of two parallel plates connected together by intermediate bridges z.
has a square or rectangular slot or recess 9 extending throughout its length, and
which is formed by the two plates and the flat spring f. In addition to this, there
is embedded in the said groove or recess a small spindle w carrying a tooth
(Figures 1 and 2) and connected with the pins by the screw b. To secure the
spindle and pin in the proper position relatively to each other, one of these parts w
is provided with a transverse groove, while the others is fitted with a tongue or
feather of corresponding shape (Figures 6 and 8).

Figure 5 is a partial front view thereof,
Figures 6, 7, and 8 are, respectively, a side view, a front view and a top view or
plan of the pin guided by a spiral spring and adapted, in conjunction with a finger
or tappet, to arrest or lock the mechanism.
Figures 9 and 10 are, respectively, a side elevation and a front elevation of a
piece inserted in the tube of the chalking device; and
Figures 11 and 12 are, respectively, a side elevation and a plan of the rack.
This billiard-cue chalking device consists of a metal tube or sleeve m over which
is fitted another sleeve or tube h, half as long as the first and perforated. This
sleeve is provided with a spiral slot or groove n, the convolutions of which have a
steep or rapid pitch. A pin or studs secured to the tube or sleeve m engages in,
or is guided by, this spiral groove, so that, when the said tube is raised, it is
thereby at the same time caused to turn, the shape and position of the spiral
groove n being such, that the said sleeve m may, in thus rising, perform a complete
revolution.
The perforated sleeve his provided with projections a to facilitate its attachment

sleeve m, after it has been forced upwards, to again descend, a spiral spring p is
interposed between the lower flanger of the said sleeve m and the sleeve or

This piece
Within the sleeve m is located a piece t, rigidly connected with the
(see Figures 1, 2, 9 and 10), and spherically recessed at its lower part.
of two parallel plates connected together by intermediate bridges z.
has a square or rectangular slot or recess 9 extending throughout its length, and
which is formed by the two plates and the flat spring f. In addition to this, there
is embedded in the said groove or recess a small spindle w carrying a tooth y
(Figures 1 and 2) and connected with the pin s by the screw b. To secure the
spindle and pin in the proper position relatively to each other, one of these parts w
is provided with a transverse groove, while the others is fitted with a tongue or
feather of corresponding shape (Figures 6 and 8).

page_text: Within the square groove o there is freely guided a rack a with a closely fitting
sleeve or case u. Within this sleeve there is arranged a narrow tube o, which the
spiral spring constantly tends to press downwards, and which is provided at its
lower part with a plate e. The spiral spring is soldered to the upper end of the
sleeve, while a pin or stop c extending through the said narrow tube o serves to
limit the downward movement of this narrow tube.
To retain in position the rack a, against which the chalk to be used in smearing
the cues is arranged to rest, a tooth or pawl y is provided, the arrangement being
such that, whenever the spindle w is turned, this tooth or pawl comes to be situated
between the teeth of the said rack. In the position of rest, the said rack is free
and will descend on the chalk placed below it, by its own weight, the spring f
preventing the said chalk from dropping out.
In order to engage and disengage the said tooth or pawl y, or to throw it into,
or out of, gear with the teeth of the rack, the pin s, with which the spindle w is
connected by the screw b, as well as by the groove and tongue above mentioned, is
provided with a finger or tappet d (Figures 6 to 8), which, while the apparatus is at
rest, remains between another tappet k and a roller v. The position of the said
finger, between these parts, is such as to cause the pawl or tooth y to keep out of
engagement with the rack &, which freely rests upon the chalk. When the
sleeve m is raised by a cue to be chalked, it turns owing to the engagement of the
pins in the helical groove n. The finger d, however, is turned at the same time,
and so is also the spindle w, whereby the tooth y comes into engagement with the
rack, and retains the same, so that the chalk lying underneath the plate e has a
firm point of support provided for it, which, however, owing to the arrangement of
the spiral spring i, is sufficiently elastic or yielding to prevent breakage of the
chalk by its being struck too abruptly. In order to bring the finger d into the
required position, and to retain it therein, the upper part of the piece, in which
the groove n is formed, is provided with a raised portion along which the finger is
adapted to slide in the position in which the rack is retained.
The piece of chalk is of square section and lies underneath the plate e between
the side plates 1, the spring serving to keep it from dropping out. The part of
the chalk slightly protruding from the sleeve is so bevelled as to complete the
spherical recess. The apparatus is secured to the wall by means of a bracket or
frame in such a manner that the sleeve m is erected vertically, the chalk protruding
somewhat from such sleeve. The cue to be chalked is pressed against the apparatus
upwardly, whereby the said sleeve m is raised and turned simultaneously, chalking
the cue as it rotates. As the cue is pressed against the chalking device, the chalk
first recedes a short distance, while at the same time the spring i presses it against
the cue; and as soon the sleeve m rises, the rack a comes into engagement with the
pawl y in the manner above described.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :
1. A chalking device for billiard-cues, comprising a tube or sleeve provided
with a pin or stud and in which the chalk is fitted, which sleeve is adjustably fitted
within a fixed sleeve or tube having a helical slot or groove in which works the
said pin or stud, so that the inner sleeve, as it ascends, will turn about its axis, a
spring constantly tending to retain the said inner sleeve in its lowermost position,
substantially as described.
2. In a billiard-cue chalking device such as we have hereinbefore described, for
the purpose of feeding and guiding the piece of chalk, the provision of a piece t
composed of two side plates, such as 1, between which is arranged a rack x fitted
with an elastically supported plate e, the said piece t being, moreover, provided
with a flat spring for the retention of the chalk, substantially as described.
3. In a billiard-cue chalking device such as we have hereinabove described, for
the purpose of retaining in place the rack &, when the sleeve in is raised, the

page_text: provision of a tooth or pawl, such as y, upon a spindle, such as w, located within
the piece t, and connected with a finger or tappet, such as d, by means of the pin s
extending through the slot n, the said finger d being so guided that, while the
mechanism is at rest, the said pawl y remains out of gear with the rack 2, while,
when it operates, the said pawl and rack are thrown into gear, substantially as
described.
4. The improved device constructed substantially as described with reference to
the accompanying drawing and operating as and for the purpose above specified.
