Referring to the drawings annexed by reference characters, 6 designates the usual staff which has affixed to it near its upper end a hollow box-like central member 7, the upper portion of this staff 6 extending up through this member to form a top handle 8. This central member 7 is desirably rec: tangular in shape to provide four vertical faces. Around the lower half of the central body 7 is arranged a row of numerals 1, I one numeral being on each face. The upper half of'the central member is provided with another row of numerals 4:, one digit being on each face. I

Slidably mounted on the rectangular cen tral member are three shields 9, 1,0 and 11, the two inner ones, 10 and 11 being adapted to telescope into the outer shield'9. These three shields are prevented from sliding oil' the ends of the central body 7 by means of a flange 12 at the upper end of the body and a similar flange 13 at the lower end of the body.

principle of operation of my invention, to-

gether sider to represent the best embodiments thereof, but I desire to have it understood with the apparatus which I .nowfconthat the apparatus disclosed is only illustrative and that the invention can be carried out by other means. Also, while it is designed to use the various features and elements in the combinations and relations described, some of these may be altered and others omitted and some of the features of each modification may be embodied in the others without interfering with the more general results outlined, and the invention extends to such use. For instance, it will be obvious that any other form of latching device may be employed.

r I claim:

1. A football down signal or marker embodying a staff, a central body member mounted on the staff, this body member being rectangular in horizontal section, and having a flange at its lower end and a flange at its upper end, the four faces of this central body member being provided around its lower portion with a row of numerals 1 and its upper portion being provided with a row of numerals 4, three rectangular shields slidably mounted on this central body member, the outer shield having its four outer faces blank and the two inner shields being pro-' vided respectively upon their four faces with the numerals 2 and the numerals 3, and means for holding each of the three shields in their upper position to thus obscure all the numerals except the row of numerals 1 on the central member, whereby the shields may be dropped one by one as the game progresses.

2. A football down signal or marker embodying a staff, a central body member mounted thereon, a series of telescoping shields mounted on said central body member, and latch-means for permitting the shields to be dropped or lowered one by one, said body member and shields being provided with numerals to indicate the number of downs to be made before losing the ball.

3. A football downmarker or signal em-- bodying a staff, a central body member mounted thereon, provided at its lower part with arrow of similar numerals and at its upperpart or zone with another row of different numerals, a plurality of shields mounted to telescope up and down on said member, the outer shield being unprovided' with numerals and the inner shields each being provided with a horizontal row of numerals, and means for holding all the shields in an up position to thereby expose only the numerals on the lower part of the main central member.

In testimony whereof I hereunto affix my signature.
