FOOTBALL DUMMY Fil'ed April 23, 1935 2 Sheets-Sheet l In/manto@ Pluma Apr. 14, 193e PATENT OFFICE FOOTBALL DUMMY Martin John Gilman, Gilman, Conn.

Application April 23,

10 Claims.

My invention pertains to athletic training devices, more particularly known as football blocking and tackling dummies. Therefore, by hereinafter referring to the Word dummy, I wish to embrace the blocking as well as the tackling dummy.

In teaching football players the art of tackling and blocking, the general apparatus employed are dummies which require either an overhead suspension device or a supporting member placed below the ground surface, or are of a self-supporting nature..

The overhead suspension devices cannot be used on the regular playing eld unless they are portable, and all of these portable devices now in use are cumbersome to handle, and are natural `obstacles not encountered in a football game.

The fact that the structure must extend into the air presents an obstacle which greatly handicaps the players, in that the art of passing cannot be properly taught under normal playing conditions.

The dummy requiring a supporting member which ls placed below the ground surface is distoa different position unless there has already been made an accommodation for the basesupporting member. Then, too, dummies employing these ground supports cannot be used on the regular playing eld, for under the best arrangements, the ground support becomes an obstacle for foot work, frequently causing in- Jury.

In the dummy of the self-supporting type, which requires no external supporting structure, the prior art discloses that the dummy, when it is knocked over by tackling or blocking, remains on the ground in substantially a horizontal position until it is again set up properly by a member o f the football squad. Moreover, this type of dummy now in use, while it affords a target for blocking and tackling, offers not sufcient resistance in construction per se, nor in reaction to properly simulate life-action. When the dummy is once hit by a player, and the center of gravity moves past the fulcrum point, it offers no resistance, and continues to fall of its own weight. Further, when a player strikes the dummy, if the point of impact is near the top, the consequent result is that the players shoulder slips over and off the dummy, the player frequently alighting on his head, causing serious bodily injury.

One of the advantages of my dummy is that advantageous, as the dummies cannot be moved,

it makes it practicable for a coach to now use,

particularly just before a game, a system of oiensive drills, wherein the defensive team is represented by eleven of my dummies, so arranged on the field that each dummy is set at a predetermined position, which is the same position as each 5 defensive player would reach at a given instance. -One formation drill may be used a number of times with slight or no position adjusting of my dummies, for when my dummy is hit, its selferecting action returns it to substantially the same location in an upright position. If the play is changed after a few drills, the defensive backeld and end dummies are, by a slight tilting of each dummy, easily and quickly rolled into the new formation. Coaching experiments have shown it advantageous to use, on a defensive dummy team, both types of my dummy, namely the type with the shoulder contact abutment ring, Fig. l, and the type without the 'abutment ring, Fig. 7.

While the drawings show the upper section of the dummy with somewhat curved lines, in actual construction the upper section is substantially a frustrum of a pyramid.

One of the objects of my invention is the provision of a self-erecting football dummy, which eliminates all overhead suspension devices or ground supporting apparatus.

Another object of my invention is to provide a football dummy, built in two distinct sections, which simulates life-action.

A further object of my invention is to provide a football dummy with a resilient doughnut-like abutment ring surrounding the upper structure, to give added resistance when acted upon by human impact.

In the drawingsz- Fig. 1 is a side elevation partly broken away to show the interior construction,

Fig. 2 is a horizontal section on the plane in- 40 dicated by line 2-2 of Fig. 1.

Fig. 3 is a detailed perspective view showing the lower portion of the top section in process of assembly.

Fig. 4 is a detailedv view of the supporting 45 clamping boards in the lower portion of the top section. l

Fig. 5 is a top plan'view of the base.

Fig. 6 is a perspective view of the base cover fastening ring.

Fig. 7 is aside elevation of a modified form.

Referring now to the drawings, and especially Fig. 1, it will be observed thatthe sponge rubber I, and a resilient durable covering 2, are 4fastened to the outer casing 3, near the bottom edge.

Canvas discs 4 and 5 are also fastened to the outer casing 3, near the bottom edge. The wooden disc Ii is slipped through the slit in the exible disc 5, and also through one of the slits in the flexible disc 4, so that the wooden disc 6 is inside the outer casing 3. The wooden disc 1 is then slipped through the slit in the exible disc 5, resting intermediate the iiexible discs 4 and 5. 'Ihe two wooden discs 6 and 1, and the two canvas discs 4 and 5, are then moved into position and fastened by bolts 8. This bottom inserting method is employed, as the opening 9, in the top of the bag 3, is obviously too small.

The abutment ring IIl` is made of flexible material, such as canvas or leather, and is cut so .that when it is fastened on the outer casing 3,

it fits nicely, and all the sewing is neatly concealed.

There are communicating ports, or openings I I, in the outer casing 3, which permit the filling of the abutment ring I0, from within the outercasing 3. The closure 9 is laced in the same manner as a football. Fastening means, known as a zipper, may also be used t'o close the opening 9. While Fig. 1 shows the abutment ring Il), filled from withinvthe outer casing 3, through communicating ports II, experiments have shown that in lieu of a filling for ring I0, which is pushed through the opening II, a unit of resilient material may be employed, such as a ring of sponge rubber. This sponge rubber or other resilient material ring may also be used with or without the covering of the abutment ring III.

A metallic shaft or rod I2, threaded on one of its ends is partially housed in the outer casing 3, with the threaded end of said rod I2, extendingthrough discs 4, 5, 6, and 1, at the bottom of the top section. Threaded collars, or nuts I3-I3', clamp tightly together the discs 4, 5, B, and 1, and cotter pins I4-I4' are inserted through holes in the rod and nuts to prevent any possible loosening of said nuts.

The outer casing 3, and the abutment ring I0, may be filled with any material such as cotton waste, wool, etc. I nd that a hair filler, as used in stuffed furniture, works very well, as it has a good inherent resiliency and is comparatively light weight.

Referring to Fig. 2, the section view more clearly shows the ports II.

Fig. 3 shows the seams of the panels of resilient material which forms the pyramid shape of outer casing 3. The sponge rubber I, and its resilient covering 2, are shown fastened near the bottom of the top section, -in a rolled-back position, before the top section is assembled on the base unit. While the resilient covering 2, of Fig. 3, for the purpose of description, is shown proportionately wider than on Fig. l, itfis understood that the width of the resilient. covering band 3, covers the sponge rubber. I, and may overlap reasonably and extend beyond the sponge rubber band.

The wooden discs of Fig. 4 shows disc 1 to have a greater diameter than disc 6. The disc 1 is somewhat smaller in diameter than the inside diameter of the base unit near the top. In Fig. 1 it will be noted that the periphery disc 1 is over the base shoulder. For the purpose of description,the dummy in its assembled form is not shown with the upper section pulled tightly to the .base unit by the nut I6. In actual construction the covered disc 1 compresses the padding I1 and I8 to such a degree, that the bottom edge of the covered disc 1 is lower than the top edge I9 (Fig. 5), of the molded base. This method of construction prevents any lateral movement of the discs 6 and 1 and gives added stability to rod I2.

Fig. 5 discloses a top view of the metallic,

molded base 20, with the shoulder I5, and holes 2|, drilled therein for insertion of the bolts 23'.

Fig. 6 shows a collar 22, which is composed of sections of wood. These sections are placed under the metallic base shoulder I5, and rigidly secured thereto by bolts 2I, which are placed in holes 23 and 2I.

The molded base 20, save for a small opening at the bottom, is covered with a padding I8, preferably of sponge rubber. Surrounding the base. at its greatest diameter, there is an additional band of padding I1, preferably of sponge rubber, to-further prevent the possibility of human injury. Both of the sponge rubber pads I1 and I8 extend up over the edge I9, and inside :of

the base 20. The`pads I1 and I8 are covered by a snug-fitting layer of canvas, or leather 24, which covers all of the outside of the base 20, save for a small opening at the bottom. The

covering 24 extends over the paddings I1 and I8 into the base20, and is securely fastened to the underside of the wooden ring 23 by screws 25.

Fig. '7 is a showing of my dummy without the abutment ring I0.

The base section 26 is completed as a unit, as is the upper section 29. 'I'he two sections are then united by inserting the threaded end of the rod I2 through'the hole 28 (Fig. 5), of the hub 21,

and clamping the upper section tightly into position by means of the nut I6. After the assembly of the two section's is complete, the protective padding I, and its covering 2, are rolledv down over the upper portion of the base section. A iiap or covering 28' is fastened over the bottom of aperture 21 by sewing or other means. The base section, while it is substantially semi-spherical or parabolic in general, it has a flattened bottom to add sturdiness while it is upright and to more casing, a filler for said outer casing, and a connecting means for uniting said base with said upper section.
