slip proof

Matt presented his solution: a patented drink holder and shelf that was a slip proof and sanitary place to put drinks.

Old Matt finished his task, and, on applying to the overseer for a fresh supply, he was set to correct a slip proof, when, taking the long column of type from which it had been printed, the old man was soon busy at work once more, correcting a misspelt word in this paragraph, removing a broken letter in that, and all the while muttering to himself, to the great amusement of the other men.

To involve the editors of the Herald in a prosecution for libel, Watt procured, by the agency of a printer in their office, a slip proof of a letter they had resolved to suppress.
