We, GUSTAVE CHARLES LALLEMAND, of 52, Rue Davy, Paris, and EDMOND DUEZ,
of 5, Place des Victoires, Paris, in the Republic of France, Gentlemen, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following state-
ment:.
Our invention has for its object an apparatus for a race game with small horses,
which we propose to call commercially "The Derby" and by means of which the
odds on the horses are changed at each race, the players do not know the odds
against the horses, until the conclusion of the race, which gives a special attrac-
tion to the game.
The game consists of an apparatus with eight horses so that it is possible to
play with one horse winning and three obtaining places, exactly as is the case
in real races. For each race the movable portion of the apparatus is turned by
means of a central knob, the odds change for each race and are indicated by
figures appearing in the opening in the fixed portion of the disc, after the movable
part has come to a stop. In this way the player when choosing a horse cannot
tell the odds until after the end of the race.
When a number of persons play the bookmaker" is chosen by casting lots.
The players agree beforehand how many races each bookmaker shall take, so
as to enable all the players to become bookmaker in turn.
"
The odds vary from evens from up to 8 to 1 against.
The stakes of the players are placed on the table on the number of the horse
chosen, either as winner or for a place. The game is always attractive and excit-
ing owing to the odds continually changing.
When 1 to 3 horses run the 1st is the winner.

placed."
When 1 to 7 horses run the 1st is the winner and 1 and 2 are "placed."
When 1 to eight horses run the 1st is the winner and 1, 2 and 3 are
All the players may stake on a horse or horses, if desired, the bookmaker paying
or receiving correspondingly.
In order to make our invention better understood reference may be had to the
accompanying drawing in which our new apparatus is represented by way of
example only.

page_text: DESCRIPTION.
The number of horses may be any desired, eight are shown in the drawing, and
the flat portion a surrounding the box b containing the mechanism, carries on each
of its lateral sides the numbers of the horses, on the front side the rules of the
game and at the back or top the name of the game. c is a central part which serves
as a support and pivot to the movable discs of the game, and is secured by small
screws or in any other suitable manner, to the base d of the box b.
The top e which partially closes the box b on its upper side is provided with an
opening (Fig. 2) of suitable shape and dimensions and hereinafter referred to.
g is the upper disc to which are secured the horses, and is mounted on and secured
to a pivot pin h entering and supported in the part c.
To the pivot h is also secured in any suitable manner a toothed wheel i, the
hub of which forms a hood over the top of the part c in order to give greater stability
to the apparatus and to diminish its height; jis a knob in one piece with or secured
to the pivot pin h by means of which the rotation of the movable parts is effected.
k is a disc to which is secured a ring on which are inscribed the odds against
the winning horse or those coming in for a place.
I
This disck is mounted on a metallic socket or cup m from which the part e serves
as a pivot, and is secured to said socket by means of screws passing through lugs
or projections with which said socket is provided at its circumference which is
suitably widened. The socket m has at its inner upper circumference a toothed
ring n, the pitch of which is the same as that of the toothed wheel i.
A small support or projection o is mounted on or secured to the part c. It carries
a fixed pin pon which is mounted loosely a small toothed pinion 9 of the same
pitch as that of the ring n and of the wheel i, and engaging between the two.
rare depending points secured to the disc k, and, preferably connected by a wire
or bands in order to make them stronger. They are arranged on each of the
imaginary radial lines forming the continuation of the separations of each of the
groups of odds required for each race and inscribed on the ring 7.

portion between any two of the points rr when the apparatus is at rest but which
owing to its flexibility does not prevent the movable part of this apparatus from
rotating when a certain effort is applied. are designs traced on the disc k and

serve to ornament the apparatus.
MANNER OF USE AND OPERATION.
The stakes of the players are placed on the numbers of the horses chosen by the
players, and a suitable impulse is given to the movable discs by means of the
knob which is sharply rotated from left to right.
Under the impulse the disc g rotates quickly from left to right, the toothed
wheel causes the toothed pinion to turn from right to left and this latter causes
the ring n with which it engages to turn from right to left at a slower speed.
When the rotary movement stops, the flexible blade u engages between two
adjacent points r r and a certain effort would be required to cause it to pass into
the adjoining interval; so that the odds corresponding to the winning horse and to
horses obtaining a place, are those which come opposite the opening f in the board e.
It is evident that we could simplify the apparatus for the game by suppressing
the ring and by recording the odds written on said ring, on the circumference
of the disck and by placing on, the circumference of said disc any projection
enabling it to be turned separately in this case the toothed wheels i, g and n would
not be required.
We could also by suppressing the toothed wheels ig and neither cause the
disc to participate in the movement of the disc g by means of a pawl gear and
operate it by turning the knob j or on the contrary cause the disc g to participate

page_text: in the movement of the disc k also by means of a pawl-gear but in this latter case
by making use of a projection or of one of the projections which would be then
arranged on the circumference of the disc for imparting rotary motion to it.
The ring on which the odds are inscribed could also form part of a disc of
small diameter arranged under the covering part e of the box b and provided with
a pivot separate from that of the disc g either directly by toothed wheels or by
toothed wheels with chains or otherwise.
Finally the odds could be arranged on a cylinder rotating in the interior of
another provided with a window or aperture in which the odds against the winning
horse and those that came in for a place would appear the spindle of these con-
centric cylinders being vertical or horizontal and receiving its movement of rota-
tion from the disc g or transmitting motion to it by means of any suitable trans-
mission gearing.
We reserve to ourselves the right of varying the shapes and dimensions of the
constituent parts of the apparatus according to circumstances and applications and
of using for making them any suitable material.
