Referring to the drawings, 1 indicates a panel or
screen, which may be constructed similarly to those used
for motion picture or slide projection, and the same bears

a pictorial representation of a bowling alley, including
the set-up pins 4 and the ?ooring 5 of the alloy. The
illustration graphically represents the aspect of an alley
This invention relates to a device for practicing the
game of bowling and for providing instructions in the
to a person standing in front of the screen. At the top,
the screen is provided with a cross member or rod 2, and
game, and more particularly to a type of device shown
in my Patent No. 2,994,969, dated August 8, 1961.
In said patent is shown a screen or panel bearing the
representation or simulation of a bowling alley, and pro
vided at the lower end of the screen is a frame having a
pivotal gate or cross piece. In practicing with the device
a simulated ‘ball-delivery swing of the arm is directed
through the frame to cause the arm practicing said swing
to contact with the gate and swing the same upwardly
provided that the swing of the arm has been directed
at the bottom it is provided with a. rod 34. The screen,
10 when in its rolled-up condition, is rolled around a rod
34 that is rotative within and con?ned with the rolled-up
screen inside of a tube 3. This construction is known
in motion picture and similar screens. The screen can be
vertically supported in any suitable way such as on a
tripod or suspended from hooks or otherwise disposed.
Adjustably mounted on the tube 3 is ‘a clip shown at
30 which may be composed of plastic or metal, said
clip being provided with an arcuately curved portion 31
properly toward the representation of the pins on the
screen.

In the use of the above-described device it has been
found that some players exhibit a tendency to impart a
lateral swing or curve to their arm after it has passed
the gate, thus failing to “follow through” with their
delivery swing and if such a swing of the arm had been
performed in actual playing of a bowling match the pos
sibility of imparting an undesirable curvature to the ball
would be likely.
It is therefore an object of the present invention to
provide an instruction and practicing device which will
eliminate the possibility of the player improperly per
forming a ball-delivery, by providing sighting and guiding
means causing a “follow through” action of the arm of
the player during a simulated ball-deliver swing of his
which springily ?ts around the tube 3 and holds itself
thereon by its resilient grip around the tube. This arrange
ment is such that the clip can be ?tted at any desired
location along the length of the tube according to the
positioning of the player and whether he is right or left
handed, and it will hold its position at any point thereon.
The clip 39 is provided with a reversely-curved hook por
tion ‘32 into which is ?tted a cross rod 11 of tubular form,
forming a part of a lower guide frame 6.
The hook
shaped part of the clip springily embraces the tube 11
while ?rmly holding it, yet it permits the tube to be ad
justed lengthwisely in the clip.
Pivotally attached at the opposite ends of the tube 11
are rods constituting arms 15 and 16. The pivots '12
which attach these arms to the tube 11 consist of disks
held together by eyelets. Flexible tongues 13 and 14
arm. It is an object of the invention to provide means by 35 extend from the disks and respectively enter the ends
which the proper delivery swing will be developed by
practice.
It is an object of the invention to provide a device of
the character described by which adjustability of the
sighting and guiding means will be had and numerous 40
other advantages will be attained.
More particularly, the invention contemplates the pro
vision of a screen or panel bearing the representation of
a bowling alley and provided at each of its upper and lower
limits with a frame acting as sighting and arm-guiding
means through which the arm-swing of the player is to
be passed in performing a simulated ball-delivery.
With these and other objects to be hereinafter set
forth in view, I have devised the arrangement of parts
to be described and more particularly pointed out in the
claims ‘appended hereto.

embodiment of the invention is disclosed,

horizontal direction is permitted by the hinge proper.

hinge 12, is a cap 17 containing a sleeve 18 (FIG. 6), with
a space 43 provided within the cap 10 and located be—

18. A stem 20 is located within the sleeve 18 and it has
a limited slidable and axial movement therein, which
movement is limited by a head 19 provided on the inner
end of the stem and located within the space 43 and re
stricted ‘by the limits of said space. The stem is freely
rotative within the sleeve 18.
Shown at 22 is a gate member which is in the form of
a. rod having a bent end extending through a hole in the
stem 22 at a point beyond the end of the cap 17. The
