Abstract

An automatic archery range including a firing line or shooting station from which arrows are fired in a flight path towards a penetrable target, a self ejecting arrow receiving and holding backstop behind the target, an arrow collector beneath the backstop, arrow return means for receiving arrows from the collector and returning them to a quiver adjacent the firing line or shooting station, a target monitor observable by an archer from the shooting station or firing line for indicating to the archer or to spectators where the arrows have hit the target and means for scanning the flight path for sensing the position on the target hit by fired arrows and operating the target monitor.

Claims

1. An indicating divide comprising:

a face adapted to have markings thereon, a first servomotor mounted adjacent the periphery of said face and operatively connected to a first arm, a second servomotor mounted adjacent the periphery of said face and spaced from said first servomotor;

a second arm operatively connected to said second servomotor and mounting a movable carriage;

said carriage being provided with a visible indicator for movement across said face, and means associated with said carriage and said first arm for moving said carriage on said second arm thereby moving said indicator to a position on said face dictated by the response of said servomotors to an input signal.

2. The invention of claim 1 wherein constant tension means are provided for biasing said carriage to an extremity of said second arm.

3. An indicating device adapted to be energized by a remotely gEnerated input signal comprising:

face means for receiving indicia arranged in at least two dimensions;

servo means for receiving said input signal and responding thereto, said servo means comprising at least two servomotors;

movable means operatively associated with each of said servomotors for movement adjacent said face means by said servomotors in response to an input signal; and

indicating means operatively associated with said movable means for indicating a point having at least two coordinates on said face means.

4. In an apparatus for indicating the location of a projectile hit in a target, an indicator face bearing a target pattern, an indicator element adapted for movement about the indicator face, a first arm pivotally mounted adjacent the indicator face to swing across the pattern area, a second arm pivotally mounted adjacent the indicator face to swing across the pattern area, means for moving the indicating element as a function of movement of both arms, and means for driving the arms.

5. In an apparatus for indicating the location of a projectile hit in a remote target as a function of two angular coordinate measurements of hit sensing means associated with the target, an indicator face bearing a target pattern, an indicator carriage adapted for movement about the indicator face, a light on the carriage to indicate a hit location relative to the target pattern, a first arm pivotally mounted adjacent the indicator face to swing across the area of the pattern, a second arm pivotally mounted adjacent the indicator face to swing across the pattern area to positions intersecting the first arm, means mounting the indicator carriage on one of said arms to move angularly with the arm and to move longitudinally along the arm, means biasing the carriage in one direction along the arm on which it is mounted, cooperating cam and follower means on the carriage and the other arm for moving the carriage along the mounting arm in opposition to the biasing means, a first electric motor connected to drive the first arm as a function of one coordinate measurement, and a second electric motor connected to drive the second arm as a function of a second coordinate measurement.

6. In an apparatus for indicating the location of a projectile hit in a target as a function of two coordinate measurements, an indicator face bearing a target pattern, an indicator carriage movable about the indicator face and having an element to indicate a hit location relative to the target pattern, a first arm pivotally mounted adjacent the indicator face to swing across the pattern area to represent one coordinate measurement, a second arm pivotally mounted adjacent the indicator face to swing across the pattern area to positions intersecting the first arm to represent a second coordinate measurement, means mounting the carriage on one of the arms for movement controlled by both arms to positions adjacent the intersection of the arms, and separate means for driving the arms variable angular distances.

7. A combination as defined in claim 6 where the means for driving the arms includes a first motor connected to drive the first arm as a function of one coordinate measurement and a second motor connected to drive the second arm as a function of a second coordinate measurement.

8. A combination as defined in claim 6 including means biasing the carriage along said one arm, and cooperating cam and follower means on the carriage and other arm controlling the position of the carriage along said one arm.

9. A combination as defined in claim 8 wherein said biasing means comprises a spring having one end connected to the outer end of said one arm and the other end connected to the carriage to urge the latter outwardly along said one arm.
