  "abstract": "A device particularly for locking a calculator to a mounting base comprises a U-shape stirrup which is secured to the bottom of the device such as by epoxy glue and which includes a reinforcing rod therethrough so that it cannot be easily severed. The complete locking device includes a bar member having a hook shaped end which engages over the stirrup in an unreleasable manner and a securement end which extends beyond the end of the device being secured so that it cannot be pivoted out of this stirrup. The securement end is secured by a securing screw which extends through a locking device comprising a first member which engages through the securing plate to the mounting base and a threaded screw which extends through the first member and engages into the mounting base and has a head portion which is covered within the first member. A second member is telescoped in respect to the first member and it includes a locking cylinder which is key operated to engage a latch into a receiving groove of the first member to lock the two members together and prevent access to the screw head.",
  "claims": [
    "1. A device for locking an article to a mounting base comprising a U-shaped stirrup connected to the bottom of the article to be secured and which defines an opening between the bottom thereof and the bottom of the article, a securing plate extending through the opening of the stirrup and having an end bent downwardly on the interior side of said stirrup preventing removal of said plate by passage of the bent end through the opening, the opposite end of said plate extending beyond the edge of the article and having a securement opening, a threaded securement member extended through the opening and secured in the mounting base and a locking device engaged over the threaded securement member and preventing access thereto.",
    "2. A device according to claim 1, wherein the locking device comprises a first tubular member having a closed end wall with an opening therethrough through which the threaded securement member extends, and a second tubular member telescoped with the first tubular member and closing the open end thereof and being locked to said first tubular member.",
    "3. A device according to claim 2, wherein said second tubular member overlies said first tubular member and includes a lock cylinder extending centrally into said first tubular member at the open end thereof, and a latch member carried by said locking cylinder being rotatable to engage within a recess of said first tubular member.",
    "4. A device according to claim 1, including a first tubular member of a size to fit through the securement opening of said plate and having an inner end abutting against the base to which the article has to be secured, said threaded securement member extending through the inner end of said first tubular member and into the base and having a head portion enclosed within said first tubular member, and a second tubular member telescopically engaged with said first tubular member, and lock means carried by said second tubular member for locking said second tubular member to said first tubular member."
