INVENTOR ROY o. WILLIAMS 37 Z BY Y WWW ATTORNEY United States Patent 3,216,724 FOOTBALL PRACTICE APPARATUS Roy 0. Williams, 126 E. Fulton Ave., Stockton, Calif. Filed July 5, 1963, Ser. No. 293,096 9 Claims. (Cl. 273-55) This invention relates to football practice equipment and, more particularly, to an apparatus for practicing blocking.
Although various kinds of dummy mounted sleds have been used for blocking practice, the present invention involves a novel mounting arrangement for dummies such that they are ideally suited for teaching the heads-up technique of blocking. In brief, the invention comprises one or more contact pads having helmet receiving curvatures or pockets. Each pad is mounted by a number of spring devices which permit the pads to pivot upon generally vertical axes. In view of the special curvature of the pads and the manner with which they can be moved, a charging blocker cannot avoid making contact with his forehead and simultaneously obtaining support from both shoulders and arms. Thus, the apparatus teaches a coordination in movement which builds confidence as well as instructing a player in the proper technique of hitting an opponent in the middle before sliding olf on one shoulder.
Various objects of this invention will become apparent in view of the following detailed description and the accompanyin g drawings.
In the drawings forming a part of this application and in which like parts are identified by like reference numerals through out the same,
FIG. 1 is a perspective ofone preferred embodiment of football practice apparatus constructed in accordance with the invention;
FIG. 2 is a side elevation of apparatus shown in FIG.
FIG. 3 is a front view as seen on line 3-3 of FIG. 2; and
FIGS. 4-6 are diagrammatic views of the dummy pad illustrating the axes upon which it may be pivoted and the effects of directional blocking.
Referring to FIG. 1, there is shown a football practice apparatus comprising a sled and a pair of identical dummy mounts 11, each mount comprising a pad 12 having a helmet receiving curvature 13. Importantly, each dummy mount is resiliently supported from sled 10 in a manner which permits pivotal movement upon generally vertical axes. For this purpose, spring loaded mounting devices 14 are provided, said devices being constructed and located in a manner to be particularly described.
Sled 11 comprises a pair of ground supported rails 15 and 16 and a platform 17. Generally upright but forwardly inclined vertical support members 18 and 19 are secured to rails 15 and 16, respectively, and inclined bracing members 20 and 21 extend between respective rails and the vertical support members. A horizontally disposed support member 22 is secured between members 18 and 19 near their upper ends. However, the ends of member 22 project beyond the ends of members 18 and 19 to support spring devices 14, as best shown in FIG. 3.
Each dummy 11 comprises a pad supporting framework 25 that is of generally rectangular shape having parallel side members 26 and 27, ofiset parallel side members 23 and 29, and horizontal connecting members 30, 31, 32 and 33. A net made of nylon cord 34 strung through loops 35 mounted to members 26, 27, 28 and 29 is utilized as a backing for pad 12. The pad may be bound to the framework by lacing, stitching, riveting or other conventional means, not shown.
3,216,724 Patented Nov. 9, 1965 ice It will be noted that curvature 13 is located centrally of the framework after the pad is secured thereto, and no hard or rigid supports are necessary to reinforce the pad in back of the areas normally contacted by heads-on blocking. The pad itself may be formed of any materials customarily used for padding purposes, but foam rubber is a preferred material. The curvature may be formed by stitching opposite sides of a solid foam pad together while the two sides are pressed together. The area of the curvature should be approximately 18 inches in diameter to receive the mask and helmet of a blocker. Preferably the depth of curvature should be about three inches deep at the center so that the helmet or face guard of a blocker will be received much the same as in actual play while both shoulders and arms make contact with the pad on areas circumferentially of the curvature. The depth of the curvature is also important for teaching a blocker accuracy in placing his head into a defending lineman.
FIGS. 2 and 3 illustrate the preferred manner in which each dummy 11 is mounted from the sled by a pair of upper spring devices 14 supported to horizontal member 22 and a single lower spring device supported from vertical members 18 or 19. The upper devices 14 are located almost equidistant from the vertical supports, thereby approximately centering the dummies 11 in front'of the vertical members. The dummies are actually set olf to one side of the vertical members and centered relative to the lower spring device. The center of curvatures 13 are positioned at a height of approximately four feet above ground. This distance is about the same as the ideal helmet contact which is made by a blocker against the body of a defensive lineman.
Each spring device 14 comprises a sleeve 36, a rod 37 that is both slidably and rotatably received in the sleeve, and a coaxially mounted coil spring 38, said spring being disposed between collars 39 and 40 on the sleeve and rod, respectively. A pin 41 mounted in rod 37 is adapted for engaging a stop collar 42 on sleeve 36 to limit movement of the rod relative to the sleeve while holding the spring under slight compression.
Sleeves 36 are mounted to sled supporting members with their respective axes extending in a generally horizontal and forward direction. They are inclined slightly downward, however, so that the dummy will be guided upward as it is moved against the power of springs 38.
Rods 37 are each pinned to the framework of dummy 11 upon a generally vertical axis by a bifurcated fitting 43 and a bolt 44. This mounting allows the dummies to be pivoted from each rod support upon a vertical axis. But in view of the three point suspension shown, the dummies will be restricted in their movement to vertical pivoting upon either axis 45 or 46, as indicated in FIG. 4. Since axes 45 and 46 are substantially vertical they provide a type of movement which closely resembles a defending player being blocked. Moreover, the pivotal movement derived from such a mounting construction teaches the importance of accuracy in blocking, while also protecting the blocker against his own errors in judgment. It will be evident from FIG. 5, that a correct head-on engagement with curvature 13 will drive the pad directly against the force of springs 38. On the other hand, a misdirected block to the right (FIG. 6) will pivot pad 12 about the substantially vertical axis 45. The unbalanced force of the springs will tend to correct the blocker while simultaneously providing sufiicient give" to guard against neck strains and, perhaps, even more severe injuries. Moreover, the type of blocking which is possible with the practice apparatus shown is actually better as an instruction aid than man-to-man blocking. The apparatus allows careful stcp-by-step perfecting of a heads-up technique 3 where the blocker hits his man in the middle, then slides off on one shoulder.
While the above described embodiment is particularly constructive for use in practicing head and shoulder contact with a defensive lineman, the apparatus is ideal for double-teaming practice. As a postman hits the curvature of a pad, the driveman can charge at full speed against the thick outside padding. Of course, the apparatus may also be used as a target for downfield block ing, both head-on and cross-body, or it may be used by a pulling guard in practicing a drive against the defensive end. In general, the apparatus shown and described has multiple uses in practicing various types of football blocks, and with relative safety compared with dummies that are rigidly held or cannot pivot to either side of center upon a vertical pivot axis.
It will be evident that the two dummy-type construction shown is of particular value since it forms a basic unit for manufacturing apparatus having as many as seven dummy mounts. Each dummy mount over two merely requires a longer sled and the use of one additional vertical support, such as 18 or 19, and a bracing member.
Although a preferred embodiment of this invention has been illustrated and described, it is to be understood that various changes may be made without departing from the spirit of the invention or the scope of the attached claims, and each of such changes is contemplated.
