Going on five months since the Rams "signed" the Squire of Great Falls as coach, the Los Angeles Times discovered the other day that the signature of George Allen either was not on the NFL West champion's bottom (or whichever) line or he'd used invisible ink. Shades of last summer, Edward Bennett Williams and press conferences in Redskin Park!

Anyway, Jon Hall of the Times, who had wondered in print what gave, ran into Allen and General Manager Don Klosterman at Anaheim Stadium and follows up:

"Both assured me that all the signatures are now in. 'It was merely an addendum to the contract that held things up, and that was a minor technicality,' Klosterman said. I asked Klosterman exactly when the contract was signed. 'What do you think - that you had something to do with it?' he laughed . . . more like a sneer. In any case, the documents now appear to be in working order. Would they kid you? Would they kid me?" . . .

We kid you not, the new Ram glamor squad of cheerleaders has been dubbed - EEEEE! - the Embraceable Ewes . . .

It's Derby Day in England, 250,000 fans headed for Epsom Downs to see 25 steeds in the 199th running. Favored: Inkerman, 6-1, with Lester Piggott up and after his ninth win in the 1 1/2-mile event for 3-year-olds, $182,000 plus a fortune in stud fees to the victor. Rated 25-1: Hawaiian Sound, ridden by Bill Shoemaker, who seeks to add the first Epsom Derby triumph by an American rider since Frank O'Neill on Snion Kop in 1920 to his record bag of 7,000 winners . . .

Paul Lambert, 43, had planned to move his family - wife Carol and daughteers Julie, 18, and Jill, 17 - to Alabama this week as he settled in as the Auburn basketball coach: it won't happen. Lambert died early yesterday when fire engulfed a second-floor section of the Airport Holiday Inn in Columbus, Ga. He was in town to codirect a two-day coaching clinic with Florida State football mentor Bobby Bowden.

Other guests fled via bedsheets hung from the balcony; Lambert was found face down on the floor of his room as though groping through heavy smoke in the blaze fueled by mattresses standing in the hallway. He had been the coach at Southern Illionis for eight years before accepting the Auburn job, a crack at Southeastern Conference glory, in April . . . Mav Rickert, who homered for the Boston Braves' only score as Steve Gromek outdueled Johnny Sain, 2-1, at Cleveland in game four of the 1948 World Series, has died in Oakville, Wash. The .247 hitter in 402 games with Cubs, Reds, Braves, Pirates and White Sox (1942-50) had retired to a farm there after working in parks and recreation in Tacoma - where as a lad he started out in the city league . . .

A. C. Jordan, director of athletics at Bowie State since 1963, is retiring to his native Lexington, Va., and friends and associates will "roast" him Friday night.
