Abstract

Abstract A multiple football tackling dummy sled apparatus comprising a rigid frame mounted upon runners to slide upon the ground and having a plurality of equally spaced rearwardly disposed horizontal arms spaced above the ground, a carriage longitudinally slidable upon each arm, a tackling dummy suspended from each carriage, means for latching the carriages at the rear ends of said arms, spring means for urging the carriages toward the forward ends of the arms and a single releasing lever for simultaneously unlatching all of the carriages. The apparatus also includes novel means whereby the spring means which urges the carriages toward the forward ends of the arms also controls the latch means which normally latches the carriages to the rear ends of the arms.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 189 words
A football tackling dummy apparatus comprising a horizontal frame spaced above the ground, upright supports for the frame, runners on the lower ends of said supports, a plurality of equally spaced rearwardly disposed horizontal track arms rigidly connected to the horizontal frame, a carriage slidable longitudinally upon each track arm, a tackling dummy suspended from each carriage, spring means normally urging the carriages toward the forward end of the horizontal frame, latch means for latching each carriage at the rear end of the corresponding arm, said latch means including an L-shaped latch bar pivotally mounted adjacent the juncture of the arms of the L-shaped latch upon each carriage and having a latch projection, a stop plate on the corresponding horizontal track arm, said latch projection being adapted to engage over said stop plate, said L-shaped latch bar having a relatively long arm and a relatively short arm, said arms being disposed at right angles to define said L-shape, the latch projection being located upon the relatively long arm and the spring means being connected to the relatively short arm, and means for simultaneously releasing all of said latch means.
Claim 2
Dependent Claim 189 words
A football tackling dummy apparatus comprising a horizontal frame spaced above the ground, upright supports for the frame, runners on the lower ends of said supports, a plurality of equally spaced rearwardly disposed horizontal track arms rigidly connected to the horizontal frame, a carriage slidable longitudinally upon each track arm, a tackling dummy suspended from each carriage, spring means normally urging the carriages toward the forward end of the horizontal frame, latch means for latching each carriage at the rear end of the corresponding arm, said latch means including an L-shaped latch bar pivotally mounted adjacent the juncture of the arms of the L-shaped latch upon each carriage and having a latch projection, a stop plate on the corresponding horizontal track arm, said latch projection being adapted to engage over said stop plate, said L-shaped latch bar having a relatively long arm and a relatively short arm, said arms being disposed at right angles to define said L-shape, the latch projection being located upon the relatively long arm and the spring means being connected to the relatively short arm, and means for simultaneously releasing all of said latch means.
Claim 3
Dependent Claim 29 words
A football tackling dummy apparatus as defined in claim 1 in which means is provided for selectively connecting the spring means to either end of the relatively short arm.
Claim 4
Dependent Claim 33 words
A football tackling dummy apparatus as defined in claim 1 in which the spring means for normally urging the carriage toward the forward end of the horizontal frame also controls the latch means.
Claim 5
Dependent Claim 113 words
A football tackling dummy apparatus comprising a supporting structure, a horizontal track arm having one end mounted upon the supporting structure, a carriage slidable longitudinally upon the track arm, a tackling dummy suspended from the carriage, a stop plate on the other end of the track arm, an L-shape latch bar pivotally mounted adjacent the juncture of the arms of the L-shaped latch upon the carriage, a latch projection upon one arm of the L-shape latch bar for engaging over said stop plate, and a coil spring having one end connected to said one end of the track arm and its other end connected to the other arm of said L-shape latch bar.
Claim 6
Dependent Claim 113 words
A football tackling dummy apparatus comprising a supporting structure, a horizontal track arm having one end mounted upon the supporting structure, a carriage slidable longitudinally upon the track arm, a tackling dummy suspended from the carriage, a stop plate on the other end of the track arm, an L-shape latch bar pivotally mounted adjacent the juncture of the arms of the L-shaped latch upon the carriage, a latch projection upon one arm of the L-shape latch bar for engaging over said stop plate, and a coil spring having one end connected to said one end of the track arm and its other end connected to the other arm of said L-shape latch bar.
Claim 7
Dependent Claim 37 words
A football tackling dummy apparatus as defined in claim 4 in which means is provided for selectively connecting said other end of the coil spring to either end of said other arm of the L-shape latch bar.
