PROVISIONAL SPECIFICATION.

I LORENTZ ALBERT GROTH K.G.V. Civil Engineer and Managing Director of
the Universal Inventors and Patentees Financial Company Limited 30 Finsbury
Pavement London EC do hereby declare the nature of said Invention for "A NEW
OR IMPROVED AUTOMATIC SIGNALLING TARGET WITH FIXED FRONT a communi-
cation to me from abroad by Pierro Ceroni of Firenza, in the Kingdom of Italy
Captain in the 25th Regiment Italian Infantry and Gregoire Bregoli of Finale
Emilia, in the Kingdom of Italy Lieutenant Colonel in the Italian Artillery to be
as follows:-
The object of this Invention is a target which will transmit the position of the
shot to the shooting station by signals or otherwise without the intervention of
markers.
The back of the target is fitted with pendulous levers or pendulums to which is
transmitted the impact of the shot this movement is used to produce a contact
between the points whereby the electric current is closed and a signal transmitted.
If it be necessary to indicate the effect of the shot on several different parts of
the target as many of these swinging bodies as wanted may be fixed to the target
and these obeying the law of parallel forces will have a greater or smaller move-
ment from the target in direct ratio to the distance from where the target has
been struck and the signal can be regulated accordingly.
The signalling may also be effected without the aid of electricity, by mechanical
means.
Instead of the button closing the circuit a wire holder is fixed which transmits
the signal The pendulum swinging away from the target its upper part formed
as an eccentric lifts the wire holder and lets a conical ferulo of the wire pass
through. Each section or number of the target has its own pendulum and wire
running on pullies and going to the shooting station.
The wires are brought back to their position by means of levers.,

DE MORFICATION
I LORENTZ ALBERT GROTH K.G.V. Civil Engineer and Managing Director of
the Universal Inventors and Patentees Financial, Company Limited 30 Finsbury
Pavement London E.C. do hereby declare the nature of said invention for A NEW
OR IMPROVED AUTOMATIC SIGNALLING TARGET WITH FIXED FRONT a communi-
cation to me from abroad by Pierre Ceroni of Firenza in the Kingdom of Italy,
Captain in the 25th Regiment Italian Infantry and Gregoire Bregoli of Finale
Emilia in the Kingdom of Italy Lieutenant Colonel in the Italian Artillery, and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
The object of this invention is to transmit an exact indication of the result of
each shot to the shooter.
The target which may be of any form or shape is composed of one or more plates
of hardened steel and is provided with pendulums or small hammers fixed to and
hanging against the back.
The impact of the shot causes the pendulum nearest to the spot struck to
rebound thus closing an electrical circuit and causing the corresponding signal
to appear while the more distant pendulums will not rebound enough to cause any
signal.
It is however preferable to divide the target into independant sections or plates
each provided with a contact pendulum.
Figs 1. 2. and 3 represent the front side and back view of the target with fixed
plates reduced to such simplicity as to be easily removed and fixed in any section
of the target.
The two lateral sections are two single plates on which the pendulums are
resting before the shot.
The middle section is divided into three parts united by iron bars, shown to
larger scale in figs 5 6 and 7 5 showing the basement and 6 and 7 the bars.
The back supports are represented by x Figs 2 and 4.
Each part acts thus independand of the others though in the same plan and
united by iron bars.
Each section has its own pendulums so that the target may be divided according
to regulations into sections of any shape or number.
The sections are about 1/2 an inch thick.
The pendulum or hammer shown full size profile face and plan Figs 8. 9 and 10
has an eccentric i which when the hammer rebounds by the fixed plate E¹ being
struck touches the lower part of a bronze cylinder to which is connected the
positive wire.
This cylinder is surrounded by an insulator of bone while the part which
supports the hammer should be protected by a case of varnished tin plate.
This target can be erected and removed from one place to another and is isolated
from the ground by wooden socket pieces b which are fixed in the stone bed T
Figs 1, 2, and 3,

page_text: Figs 11 and 12 show respectively front and profile of a saloon target with fixed
plates.
It is necessary that the battery should consist of a number of elements pro-
portional to the intensity of current required For one target up to 1,200 ft 3 cells
are sufficient.
The wire from the negative pole may be attached to any part of the target that
from the positive pole should be connected to the bronze cylinder † Figs 8. 9
and 10.
The electric current marks the corresponding number or part on the signboard to
that struck on the target.
The signals may be transmitted by mechanical instead of electrical energy in the
following way
Instead of the bronze cylinder a conical ferule is held by means of weights
against a perforated plate through which it is prevented (by means of an eccentric
on the hammer) from passing through Figs 13 and 14 and thus prevents the wire
being pulled till the section has been struck.
When the pendulum leaves the plate the eccentric on its upper end moves the
plate enough to let the ferule pass through Figs 15 and 16 thus allowing the
weights to pull the wires.
Each section of the target has its own ferule and stop plate wire and weight
the wires are carried by small pullies Figs 18 and 17 placed at intervals between
the target and the shooting stand where they are regulated by the aid of a small
lever for fixing the position of the wire or for showing the corresponding
number g on the signboard until either by the equilibrium or the manipulation of
the lever it is replaced ready for action.
The advantages of this target ar
1st An exact record of the result of each shot.
2 Simplicity and facility of management.
3 Economy of cost, wages of markers dispensed with and consequently no
dangers to such men.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
dangers to such men.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. A target the face of which is composed of fixed plates each of which has a
hammer or pendulum at its back which rebounds by the impact of the shot thus
completing an electrical circuit by means of an eccentric and a contact cylinder and
causing a corresponding part or number to appear on the signboard.
2. The substituting of mechanical instead of electrical power for producing the
above results consisting of wires actuated by weights and controled by a ferule
acting against the eccentric of the hammer as before described.
