6 Claims. 1

This invention relates to improvements in football practice apparatus for use in teaching, training and developing football players, and more particularly to a device commonly referred to as a charging sled.

An object of the invention is to provide a novel and advantageous apparatus by means of which football players may be taught, trained and developed in the art of football maneuvers. I

A further object of the invention is to produce a novel charging devic that is not confined to the teaching, training or developing of individuals, but which is especially useful in carrying out mass tactics, resulting in' the development of precision timing and team work.

A still further object of the invention is to permit the ready comparison of players in action and instantly to reveal carelessness, laziness, lack of ability, lack of spirit, or lack of condition of any player.

Other objects of the invention are to train players to line up quickly, to charge in unison, or for some to delay and for some to charge, to charge hard and low, to train players to pull out of the line and lead interference after running around the other linemen, and to develop speed, strength, and agility in the players individually and as a group.

The above and other objects may be attained by employing this invention which embodies among its features a plurality of filled dummies arranged on a frame so as to compress upon being hit by a charging player and then to remain compressed upon the continued push of the player and then to move over the ground on runners offering heavy resistance to the charging players. An arrangement has been Worked out whereby a bell or light will indicate what players are charging and which are not. This latter feature overcomes the previous objections to a group trainer such as this wherein it has been chronically complained of that some of the players would not extend themselves since there was no available way to detect their laziness.

With the foregoing, other objects of this invention will appear from the embodiments of the invention which by way of example are described in the following specifications and illustrated in the accompanying drawing, in which- Figure 1 is a perspective'vlew of the entire sled from th rear.

Figure 2 is a perspective view of one of the dummies from the front. I

Figure 3 is a front view of one of the dummy supporting members with the dummy and box removed.

Figure 4 is a side view of one of the dummy supporting members with the supporting box and with the dummy broken away.

Figure 5 is a side view of a portion of one of the supporting members, the box, and the dummy.

Figure 6 is a top view of Figure 4.

Figure 7 is a wiring diagram of the bell box and the contacts of the support box.

Referring .to the drawings l represents the runners, and 2 represents the struts or braces. These struts 2 are connected between the girder '3 which is fastened or bolted to each runner l, and the vertical supporting members 4. In the embodiment shown, an L shaped girder 5 is fastened to the runners I and to each of the vertical supporting members 4. A top girder or brace 6 is connected near the upper portion of the vertical members 4 and above the struts 2. This girder 6 not only acts as a brace but it also is a spacer member. This above description can be more easily ascertained by reference to Figure 1.

In Figure 3 one of the vertical support members 4 is shown. Mounted on each side of this member is a stirrup or supporting clamp 8. By referring now to Figures 4 and 6, it can be ascertained that a box means comprising a side portion 9 and a front portion I0 is mounted within the stirrups 8. This box means is further supported by a compression member H which is movably fastened to the front portion H] by means of a hinge means I2. A wedge means I3 is sandwiched between the compression member H and vertical support member 4. Thesethree members are rigidly fastened together by bolts I l.

The wedge means I3 is preferably made of spruce wood whilethe compression member H is of oak. It has been found that this combina tion provides both the necessary strength to stand up under adverse conditions, but also enables a large amount of tension to be exerted upon the member ll without the concern of inury.

Mounted between the member l and the front section [0 are two springs [5 of the coil type. These springs maintain thebox means, members 9 and [0 forward of the member 4 as well as maintaining the surfaces of IO and II apart.

Between these springs and slightly higher as can be seen by reference to Figure '7' are a pair of electrical contacts l6. These contacts are connected by wire l8 to a bell box I! which is mounted on the member II. In the bell box are a battery l9 and a bell 20, which are in a series electrical circuit with the contacts I l An incandescent lamp 2| is shown connected in par allel with the bell 20 and could be used either with the bell or without it, by changing the wir-- ing to include or exclude either of these signalling means from the circuit.

Figures 5 and 6 show in more detail how the dummy or filled sack 1 is mounted to the box means 9 and 10. A long c type clamp 22 is used on either side of the dummy to maintain it rigidly against the sides 9 of the box means- 9 and II]. It is to be noted that the dummy 1 has backing members 23 which are part thereof. Thes members are designed to fit around. the box so that the clamp 22 will perform its func tion efllciently. Other methods of mounting the sack I to the box means can be employed and would not be outside the scope of this invention.

The designation [4 indicates a nut and bolt for maintaining the various members in connected relationship. Wood screws 24 are used to maintain the stirrups 8 in locked relationship with the supporting member 4.

In operation the football players line up against the dummies 1. Upon word from the coach they charge against the dummies I. Since the runners I offer resistance to the ground, at first only the box assembly 9 and III will move in the stirrups 8 closing the member ID with the member ll upon the hinge I2 and compressing springs l5 and closing the contacts l6. Upon closing these contacts 16 current flows from the battery is through the bell 20 or light 2| through the contacts l6 and back to the battery I9. The bell 20 will be energized and continue to ring so long as different colored lights for various situations. It i is also contemplated that a whistle or horn might well be employed instead of the bell. Upon the continued push or charge of the players, the runners I will overcome the resistance of the ground and the entire assembly will move. If one of the players does not push equally with the others his light will become extinguished or his bell will stop ringing since the contacts I6 will notremain closed.

In Figure 6 it is to be noted that the springs l5 cover the exterior of a piston 3| and cylinder 30 assembly. When the spring [5 is compressed due to the compression of members 10 and H, the piston 3| enters the cylinder 30. This arrangement maintains the spring rigid and allows it to move only in one direction. The dimensions of the piston and cylinder are contemplated to enable the faces of the contacts 16 to make.

The wedge 13 enables the compression member l I to move laterally within limits toward the member 4. Since member I!) is movably connected to member I l by the hinge [2, the movement of l I and [0 will impart movement of member 9 through the stirrups 8. As soon as there is no pressure on member H, the wedge 13 with its inclined surface will return member H to its original position imparting this returning movement to members 9 and Ill.

The dimensions of the various features have been exaggerated in the drawings to give a clearer picture of the invention.

It is to be understood that the invention is not restricted to the precise arrangement of the parts shown and described, as detail of construction may be modified and rearranged without departing from the spirit of the invention, the scope of which is limited only by the terms of the appended claims.
