Mechanical baseball umpire
Abstract
A vertically suspended loop to which a flexible net is attached
serves to judge if a pitched ball approximately passes through the
strike zone above the batter's plate in the game of baseball (or a
related game). A pitched ball, not swung at by the batter, which
passes through the loop and is subsequently retained by the net
shall be called a "strike," whereas a pitched ball, not swung at,
and not passing into the net shall be ruled a "ball." The loop is
suspended by suspension members between a pair of vertical, spaced
apart posts such that the posts and loop all be substantially in
the same vertical. The loop being suspended at a height above a
support surface which is substantially the height of the strike
zone of a batter.

Claims
Having described the invention, the following claims are hereby set
forth:
1. A mechanical baseball umpire comprising:
a pair of elongated vertical support posts spaced a preselected
distance apart, each having a series of vertically spaced eye bolts
attached thereto intermediate its ends; a net structure, said net
structure having a net member formed as a pocket having a closed
bottom portion and an open top portion, said top portion being
secured around the periphery of a loop to form an open pocket, said
loop having a pair of elongated suspension members attached
thereto, each of said suspension members having means at its free
end to fasten said suspension members to eye bolts for suspending
said loop and net from said pair of posts such that said loop lies
in a substantially vertical plane between said post, said fastening
means being disengagable from said eye bolts for vertically
adjusting said loop and net on said posts, said post net and loop
arrangement serving as an umpire in the sense that when a ball is
thrown through the loop and retained by said net a "strike" is
designated and when a ball does not pass through said loop a "ball"
is designated.
2. The mechanical baseball umpire of claim 1 wherein said fastening
means are swivel snaps.
3. The mechanical baseball umpire of claim 1 wherein said support
post are hollow and are separable into top and bottom sections,
said top section being telescopically inserted into said bottom
section, said eye bolts being attached to said top section.

SUMMARY OF THE INVENTION
A loop to which a flexible net is secured is vertically suspended
from two poles, and serves to objectively determine if a pitched
ball approximately passes through the strike zone above the
batter's plate in the game of baseball (or a related game). The
poles are secured in the ground (or floor) to the rear of the
batter's plate, and on a plane that is parallel with the front of
the batter's plate. The loop (with the attached net) is suspended
from the poles from one of several positions depending upon the
height of the individual batter; the strike zone in the game of
baseball is that area of space over the batter's plate which is
between the batter's shoulders and his knees; thus the loop must be
suspended in a position that is directly behind the batter's plate
and adjusted to be between the batter's shoulders and his knees.
When a ball is thrown from a distance and passes through the loop
in flight and is subsequently retained by the attached net, a
"strike" shall be called on the player at bat. A pitched ball, not
swung at by the batter, that does not pass into the loop shall be
called a "ball.
BRIEF DESCRIPTION OF THE DRAWINGS
In the drawings FIG. 1 is a perspective view of the mechanical
umpire in use; and FIG. 2 is a front view of the structure of the
mechanical umpire.
DETAILED DESCRIPTION OF THE INVENTION
Refering to FIGS. 1 and 2, loop 14 to which a flexible net 16
having its perimeter secured to loop 14 (and including a bottom
portion located below the level of loop 14) is vertically suspended
from two poles each of which is composed of two separate sections
10 and 12, and secured in the ground (or floor) perpendicularly,
the loop 14 being fastened to one of the eye bolts 18 on each upper
section 12 of each pole by a chain 20 which is affixed to loop 14
and snaps onto the eye bolt 18 by means of a swivel snap 24.
When a ball 26 is thrown by a player 28 from a distance through
loop 14 and thus into net 16, it is assumed that the ball 26 passed
through the strike zone (that space directly above the batter's
plate 30 which is between the shoulders and knees of the player at
bat 32) and a "strike" shall be called; when a ball 26 is thrown
from a distance by a player 28, the batter 32 does not swing the
bat, and the ball 26 does not pass through loop 14 into net 16, a
"ball" shall be called.
The ball 26 can be hard or soft since the structure of FIG. 2 can
be of steel, aluminum, plastic, or any other viable material, and
the lower sections 10 of the poles can be either pushed slightly
into the ground or permanently secured therein, or permanently
affixed to the floor.
Although this invention has been described in reference to a number
of particular drawings, such is not to be considered as limiting
its actual scope.
