‘ My invention relates to an improvement in
target ri?e ranges of the type in which a ri?e or
revolver or gun or the like is'employed to shoot a
?ash or ray of - light, of short duration, at a
#5. target Which includes a photoelectric cell.‘
One purpose of my invention is to provide an
‘improved range of the type above described, in
which the photoelectric cell is mounted on a mov
Another purpose is the provision of improved
means for connecting the photoelectric cell on
the target with an ampli?er normally ?xed in
relation to the housing in ‘which the moving
target portions are housed.
Another purpose is the provision of improved
means for counting the shots ?red or the trigger
pulls in order to limit the number of trigger pulls
available, in a coin operated .machine, for each
coin insertion.
Another purpose is the provision of improved
scoring means or score recording means.
Another purpose is the provision of improved
means for controlling the drop portionvof the
target whereby,‘ when the photoelectric cell ‘of
the target is struck, a drop, which may simulate
a bird or animal, falls to indicate a hit.

A brief description of the gun mechanism is as
is provided with adjustable abutments 33, 34,
follows: Each time the trigger 56 is pulled, it
actuates the movable stem 12 which in turn, by
at its lower end, which may be screw-threaded
in relation to it and which receive between them

25 tromagnets 36 or 38a in any suitable fashion upon
a lower portion of the arms l3 or I4. It will be
understood that the armature may be slotted as
at 31 in order to prevent any binding of the parts
when the armature 35 is rotated through its per
30 mitted arc of movement in response to excite
ment of the electromagnet 36. The downward
movement of the armature may also be limited by
any suitable abutment 38. The slotting of the
latch 26, as at 21, similarly prevents binding at
35 the upper end of the rod 32.
It will be understood, of course, that I may
provide a wide variety of means for releasing
the drop and for holding it in position until
released, but the’ above described structure is
40 practical and operative.

The drop members It, once they have been
released by action of the electromagnets 36, 36a
and rod 32, releasing the catch 26, are returned
to initial position by gravity, as the arms l3
45 rotate to position below the axis of rotation of
the shaft 8. In order to insure the return of the
drops Hi to vertical position, I may also employ
tarilyopens the shutter 81.
The shutter 81, which normally masks the light
53, thus permits a beam of light to escape from
the gun barrel 5|.
The trigger pull has an additional function,
namely that of closing the gun switch which in— 30
cludes the opposed switch spring contacts I09
and. mm. This result is obtained by the engage
ment of the knob 62 with the outer end of the
leaf I09, as shown in Figure 1, the knob 62 being
of insulating material.
Referring now to the general schematic circuit
layout, as shown in Figure 1, I illustrate terminal
lines a and al. The terminal line a connects to
one side of the coil a3 of a transformer generally
indicated as T. A switch a2 is shown which may
be manually operable to terminate the operation
of the entire machine. The line a1 extends to the
opposite terminal of the primary coil a3. In par
allel across the lines a, a1 is the line a4 in which is
the motor H. (15 indicates any suitable switch 45

Another‘ result of the trigger pull is‘the thud‘
to caused by the impact of‘ the hammer I I2 against
the opposed abutment I I3 which simulates‘ or
suggests the sound of a shot, and which takes
place at each trigger pull.
‘After the tenth trigger pull,‘ the notch I20 is
again in line with the off-‘set portion of the
switch leaf B15 and permits that‘switch to swing
out of contact with the opposed switch 1114.
This breaks the shunt connection between the
trigger switch I00 and I00a,‘ and the insertion of
to another coin is necessary to start thedevice.
The ampli?er circuit and the circuit for the
scoring or score recording device may be de
scribed as follows:
The photoelectric ampli?er cooperates with the
‘1 photoelectric cells 22 and 22a when one of the
photoelectric cells is struck by a ?ash of light
‘ from the gun C as generally indicated, as in Fig
ure 1,‘ by the ‘letter P. It will be understood that
the‘power for the ampli?er is received from the
commercial power circuit including‘ the lines a
and a1; which operate the transformer T.

The connection between the photoelectric cell
22 and 22a and the photoelectric ampli?er P is
as follows:
Tracing from the contact or terminal 09 is the 20
line 010 to'the ?xed contact 42a in contact with
the ring 42. Extending from the ring 42 is the
conductive line 011 to the junction 012 where it
branches as 013, 014 to the photoelectric cells 22
and 22*‘, respectively. Return lines 015 and e16 25
are provided from the two photoelectric cells
which join at the junction 01'7 with the line 018
which extends to the ring 43. 43a is another ?xed
contact opposed to'the'ring 43 and‘ from it ex

excite the photoelectric relay (1 which, when ex—1
cited, closes the moving switch contact 111 against 35

may be traced. from the secondary coil bi of the
transformer T through the line b1 to the junc
tion d3, along ‘the lined4 to the junction d5 along
the line d6 to the electromagnet d", and thence
along the line 018 to the junction 11*‘, and, by the
line d1‘), to the ?xed switch member 012. In other
words, a circuit is closed which'excites the elec
tromagnet d7 and moves the armature d11 which,
when moved, lifts the lever arm d12 and‘ moves 45
the dog 0313 against. the ratchet (Z14 and advances
the scoring drumv (115 one step. Thus at each
actuation of the electromagnet d\7 and‘ the ‘armae
ture (ill, the drum (115 is advanced one unit, each
unit being? given an appropriate number, and
the total number of advances'of the drum (115 50
equallinglthe total number of hits‘made against _
one or the other of“ the photoelectric cells 22 or
22s. The score indicator‘is visible through the
window dl?, in the front of the cabinet shown in 55
It will be understood ‘that a spring all7 tends
normally to keep the armature in the position in
which it is shown in Figure 1. The spring (118
is‘to keep the dog (213 in the position in which it
is shown against the stop ‘(£19. The function of
the spring (Z25 is to cause the drum (Z15 and its as
sociated parts to return to initial position, which
movement is normally resisted by the detent d2",
held in the position in which it is shown by the 65
spring dill ofgFigure 1.

The circuit controlled'by the relay d and the
switch members d1 and d2 is continued from the
switch d1 by the line ‘(122 to the junction L123 and‘
by the line d24 to the junction 08' where it joins

' In order to- reset the‘drum (Z15 to initial position
I provide the following circuit which branches ,
from the line 03 at the junction 04 as follows:
The line e extends from the junction c4 to the 75
electromagnet e1 and-continues by the line e2 to
the junction 1123 and through the line 1124 to the
junction 08, and line b1° which closes the circuit
through the secondary coil b of the transformer
T and through the switch elements 01, c2 of the
shot limit structure. As long as the switch struc
ture c1, 02, that is to say, as long as the switch
member 1915 is riding on'the periphery of the cam
disc H3 and has not yet dropped into the notch
10 I20, the circuit through the electromagnet e1 is
closed. At the tenth shot, when the connection
between the switch members 01 and c2 is broken,
and the circuit is broken through the electro~
magnet e1, the armature e3 is drawn by the
15 spring 64 into the position in which it is shown
in Figure 1, and the latch e5 slides forward away
from the abutment e6 and its latch or head por
tion c7 rides over the pin e8 on the detent (12°
in readiness to release the detent d20 and to per~
20 mit the spring (125 to rotate the parts back to
initial position, any suitable stop means being
provided to terminate the retrograde movement
of the drum (215 when the symbol 0 is alined with
the aperture (Z16, as shown in Figure 2. When
the device is again set in movement by closure of
the coin operated switch S, the electromagnet e1
is again excited and draws to itself the armature
e3. When it does so, it moves with it the detent
d2", permitting the spring (125 to move the drum
30 (1“ back to the zero position. By the time the
detent has cleared the teeth of the ratchet wheel
d“, the hump e9 of the latch e5 moves over the
abutment e6, causing the latch e5 to lift and
release the detent d2", to the position in which
35 it is shown in Figure 11.
As long as the circuit
continues closed through the switch members 01,
c2, the parts remain in that position. The detent
d20 prevents retrograde movement of the ratchet
d“, while allowing its forward step by step move
ment in response to actuation of the arma
ture (Z11.
In order to actuate the drop structure, shown’
for example in Figure 4 and including the drop
members 16, I provide the already described elec
tromagnets 36 and 36%, only one of which can
work at a time, because of the employment of
the split ring segments 44 and 45 already de
scribed. The connection there formed from the
transformer T and its secondary coil 1) may be
traced by the line d4, through the junction d5,
by the line 9 to the normally ?xed contact Me,
the ring 4 l , the line g1, through the electromagnet
36, back by the line g2, to the upper segment 44,
the normally ?xed contact 46, and the line 93
to. the junction (29, through the line c110 and switch
members d2, (11, back along the line (122, junction
(123, the lines d24 and 121° to the secondary coil 1)
of the transformer T.
Similar lines are shown and similarly indi
cated, extending to the electromagnet 36a, in con
nection with the ring 45. It will be understood
however, that only the top drop can ever be shot
at and only one can be shot at at a time and only
one of the electromagnets 36, 36a can operate at
one time.
It will be realized that, whereas I have described
and illustrated a practical and operative device,
nevertheless many changes may be made in the
size, shape, number and disposition of parts with
out departing from the spirit of my invention. I
70 therefore wish my description and drawings to
be taken as in a broad sense illustrative or dia
grammatic, rather than as limiting me to the
precise showing.
In particular, I wish it to be understood that I
am claiming primarily a target range and do not
intend to limit myself to the particular circuits
employed, since a wide variety of substantially
equivalent circuits may be employed, which may
differ greatly in general detail and tracing, while
obtaining the same, or substantially the same,
result. I therefore do not wish to be limited to ll)
the speci?c structure and circuits here shown
except to the extent in which I positively limit
myself in the language of the claims. I also
wish it to be understood that the photoelectric’
ampli?er employed may vary widely, and vthat it
may be practical to put it in continuous circuit
and control the motor circuit by the coin switch
structure herein shown. In other words, this
involves reversing the position of the ampli?er
and motor in the diagram of Figure l, a reversal 20
which would be perfectly clear to any skilled
operator in the art.
It will be understood, however, that the am
pli?er employed is not a source of power for
operating the structure herein shown but is 25
merely a means of controlling or actuating the
elements involved in response to the excitement
or closure of the photoelectric ampli?er relay as
a result of hits recorded against the photoelectric
cells. It will be understood, therefore, that a 30
wide variety of changes may be made in the wir
ing diagram herein shown without departing from
the spirit of my invention and scope of my claims.
