4 Claims.
This invention relates to game apparatuses.
It is an object of this invention to provide an
(Cl. 273-1)
Other objects will appear hereinafter.
The invention consists in the novel combina
improved game apparatus which is relatively
tion and arrangement of parts to be hereinafter
simple and inexpensive in construction and eili
described and claimed.
5 cient in use.
In a game apparatus of the so-called pin and
marble game type it is customary to employ an
elevating device for elevating the balls, upwardly,
one at a time, from a point below the ball play
10 ing surface up to the level of the same. Many
different types of ball-elevators have been used,
such, for example, as spring-urged' elevators,
electrically operated elevators, and the like. One
of such elevating devices is that shown and de
15 scribed in the MacDougall Patent No. 1,983,811
granted December 11, 1934, and in which the
action of a ball closes circuit to an electromag
net which, when energized, operates the ball
elevator or carrier so as to elevate the ball from
20 a point below the ball playing surface up to the
level of the same. It has been found, however,
from experience in the art, that in the use of a
ball elevating device of the types heretofore
known, there is a decided tendency for the ball
25 elevator or carrier to elevate the ball too rapidly,
that is, the ball carrier or elevator gathers mo
mentum and its speed increases rapidly, during
its ball-elevating stroke or movement, so that
when it reaches the upper end of its stroke it
30 is moving at a relatively rapid rate of speed and
`
The invention will be best understood by ref
erence to the accompanying drawing, showing
the preferred form of construction, and in which:
Fig. 1 is a perspective view showing a preferred
embodiment of the new ball-elevating device;
Fig. 2 is a vertical sectional view illustrating a 10
preferred form of the new ball-elevating device
associated with a pin and marble game of con
ventional design; and
Fig. 3 is a diagrammatic view of an electrical
circuit embodied in the present invention.
A preferred embodiment of the new ball ele.
vating device is shown in the drawing, is therein
generally indicated at I0, and is shown associated
with a so-called pin and marble game of con
ventional design, said game including a cabinet 20
II embodying an inclined playing board I2 onto
the upper portion of which balls may be pro
pelled in a manner which is well understood in
the art.
Arranged below the inclined playing
board I2 is a ball return runway I3 by means 25
of which balls may be conducted, from ball- '
receiving pockets provided in the inclined play
ing board I2, to the elevating device ID.
Provided in the inclined playing board I2 is
an opening I4 (Fig. 2) and arranged above this 30
consequently discharges the ball too rapidly and
violently out onto the ball-playing surface. This
opening I4 is a hood or ball-deilector I5 by means
of which balls may be deñected onto the in
is objectionable for a number of reasons among
clined playing board I2, this structure as thus far
described being substantially similar to that
shown and described in the aforesaid MacDougall
which are the fact that the ball thus elevated and
35 discharged too rapidly out onto the playing sur
face tends to overrun its mark, that is, to go
beyond the point where it is desired to deposit it,
and it tends to bound against and strike the glass
top of the cabinet and break the same, as well
40 as having other objectionable features with which
persons skilled in the art are familiar.
It is, therefore, another object of the present
invention to provide a ball-elevating device for
a pin and marble game which will overcome the
4
foregoing and other difiiculties experienced in
the use or” the prior art elevating devices and
which in use will elevate the ball relatively slowly
and at a substantially uniform rate of speed.
50
Another object of the present invention is to
provide a ball-elevating device which embodies
means for overcoming or counteracting the tend
ency of the ball elevator or carrier to gather mo
mentum and increase its speed as it moves toward
-55 the upper end of its stroke.

Y
Having thus described, in general, the environ
ment in which the new ball elevating device is
used, the same will now be described in detail.
The new ball elevating device I0 comprises a
substantially channel-shaped ball carrier
I6
which is pivotally mounted adjacent one end, as
at I‘I, upon a suitable support I8 which is ar
ranged in the cabinet I I below the inclined play
ing board I2. The ball carrier has an angled
end portion or cam edge I9 which extends at
an angle relative to the long aXis or main extent
of the ball carrier I6, and engageable with this
angled end portion or cam edge I9 of the ball
carrier I6 is a member 20, having the form of
a bolt, and this member 20 is adjustably mounted
in, and forms an extension of, the movable ele
ment or armature 2l of an electromagnet 22 which
is mounted in the cabinet II below the inclined
playing board I2, this member 2| being pivotally .
2,101,354
mounted, adjacent Aits lower end, as at 23, and
being urged, by a spring 24, in a direction away
from the electromagnet 22 (clockwise, Fig. 2).
Provided in the ball carrier I6 is an opening
25 and normally projecting into this opening 25
is an angled portion 26 of a resilient contact 2l
which is attached to, and is carrie-d by, the ball
carrier I6. Likewise attached to and carried
by the vball carrier I6 is a second contact 28,
10 these contacts 2l and 28 forming a switch 29.
This switch 29 and the electromagnet 22 are
arranged in an electrical circuit 39 (Fig. 3),
and this circuit 30 includes, in addition to these
parts, a suitable source of current 3| which may
be, for example, a battery of dry cells arranged
in the cabinet Il.

upper end of its stroke it is moving substantially
at the same speed, or possibly somewhat slower,
than at the start of its movement, and in this
manner the ball disposed in the ball carrier I6
a suitable support 33 provided therefor in the
onto the inclined playing board I2, thus over
coming the above-mentioned and other diñicul 20
ties experienced in the use of the prior art ele
vating devices hereinbefore referred to.
It will be noted that the extension 20 of the

through its operative or ball-elevating stroke,
and hence when the ball carrier I6 reaches the
is discharged relatively slowly and not too rapidly
When a ball traveling down the ball return
runway I3 enters onto the ball carrier I6 it
travels, by gravity, over the latter toward the
lower end portion 32 of the same and in so do
ing passes over the angled portion 26 of the

stantially uniform and constant as it moves
The ball carrier I6 has a relatively free and
posed in its normal or initial position it is in
clined slightly from the horizontal so that a ball
traveling down the ball return runway I3 will
run onto the ball carrier I6 and travel down
to the lower end portion 32 of the same.

its speed is overcome and counteracted and the
speed of .the ball carrier I6 is maintained sub
angled end portion 32 which normally rests upon
20 cabinet II, and when the ball carrier I6 is dis

4effective force or leverage, applied by the member
2I-2Il in the angled end portion I9 of the ball
carrier is gradually reduced as the member
20--2| and the ball carrier IB-I9 move through
their effective strokes and the extension 20 of
the member 2| approaches closer to the fulcrum
I'I, and in this manner the tendency of the ball
carrier I6 to gather momentum and increase
contact 21 which projects through the cut-out
opening 25 which is formed in the ball carrier
I6, thereby forcing the contact 2'I into yengage
ment with the contact 28 and thus closing the
switch 29 and the circuit 30 in which the switch
29 is arranged.
When the switch 29 and the circuit 36 are
thus closed, the electromagnet 22 is energized,
and thereupon attracts its movable element or
armature 2|, against the action of its resetting
spring 24, and during this movement of the
member 2| (counterclockwise, from full to dot
ted line position, Fig. 2) the extension or adjust
able portion 20 thereof engages the angled end
portion I9 of the ball carrier I6, thus pivoting
the ball carrier I6, at I'I, in a direction (clock
wise, from full to dotted line position, Fig. 2)
to elevate a ball up through the opening I4 and
hood I5 onto the inclined playing board I2.
Atthe start of the movement of the member
2I-26 and the ball carrier Iii-I9, it will be
noted that the force applied by the member
2I-20 against the angled end portion I9 of the
ball carrier I6 is applied near the lower end of
the angled end portion of the ball carrier I6
and at a considerable distance from the fulcrum
or pivot point I‘I of the ball carrier I6. How
ever, as the member 2I-2I) and the ball carrier
I6-|9 move through their eiiective or operative
stroke (counterclockwise and clockwise, respec
tively, Fig. 2), the extension 20 of the member
2| approaches gradually closer to the fulcrum
65 or pivot I'l of the ball carrier I6 and hence the
member 2|, that is, the bolt 20, is adjustably
mounted in the member 2| and by adjusting
this member 20 either toward or away fromA the
angled end portion I9 of the ball carrier I6 the
arc through which the member 2| is moved,
that is, the extent of the movement of the mem
ber 2| may be varied.
30
While I have illustrated and described the pre~
ferred form of construction for carrying my in
vention into effect this is capable of variation and
modiñcation, without departing from the spirit
of the invention.
I, therefore, do not wish to be .
limited to the precise details of construction set
forth, but desire to avail myself of such varia
tions and modifications as come within the scope
of the appended claims.
Having thus described my invention, what I 40
