Abstract
Abstract A device to prevent theft or other unauthorized removal of portable equipment, such as typewriters, adding machines and the like, from their normal location or places of use. The protective device comprises a bar readily attachable by fasteners passing through the bar and through openings in the desk top, shelf or other supporting member, and into the base of the piece of portable equipment. The latter is thus held in firm engagement with the supporting member. Access to the attaching bar and fasteners is prevented by a trough-like member which encases the attaching bar and the fasteners. The encasing member is provided with lock means for securing it in position, so as thereby to prevent any but an authorized person from gaining access to the fasteners associated with the attaching bar.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
183 words
A device for preventing removal of portable equipment from a supporting member, comprising (1) an attaching member of substantially flat cross-section adapted to be positioned on the bottom surface of said supporting member and having removable means associated therewith for fastening such equipment to the upper surface of said supporting member, and (2) an elongated shield member engageable with said attaching member, said shield member comprising a pair of spaced substantially parallel side walls each integrally joined at one of their edges by a bottom wall and extending in a plane at right angles with respect to the plane of said bottom wall, said bottom wall being substantially imperforate throughout its length, said shield member serving to completely envelop and encase said attaching member and said removable fastening means when the shield member is in full engagement with said attaching member, said shield member having a locking mEchanism fixedly attached therein between said side walls at one end of the shield member, said locking mechanism including a key operable locking element to render said shield member immobile with respect to said attaching member.
Claim 2
Independent Claim
183 words
A device for preventing removal of portable equipment from a supporting member, comprising (1) an attaching member of substantially flat cross-section adapted to be positioned on the bottom surface of said supporting member and having removable means associated therewith for fastening such equipment to the upper surface of said supporting member, and (2) an elongated shield member engageable with said attaching member, said shield member comprising a pair of spaced substantially parallel side walls each integrally joined at one of their edges by a bottom wall and extending in a plane at right angles with respect to the plane of said bottom wall, said bottom wall being substantially imperforate throughout its length, said shield member serving to completely envelop and encase said attaching member and said removable fastening means when the shield member is in full engagement with said attaching member, said shield member having a locking mEchanism fixedly attached therein between said side walls at one end of the shield member, said locking mechanism including a key operable locking element to render said shield member immobile with respect to said attaching member.
Claim 3
Dependent Claim
41 words
A device as defined in claim 1, wherein said attaching member comprises an elongated, substantially rectangular bar formed with a centrally disposed, relatively narrow opening extending longitudinally throughout substantially the entire length thereof for the reception of the said fastening means.
Claim 4
Dependent Claim
39 words
A device as defined in claim 2, wherein said bar is formed at one of its ends with a flange, said flange being disposed substantially at a right angle to the plane of the main portion of the bar.
Claim 5
Dependent Claim
