Abstract: A locking cover for the ends of an electric meter retaining ring comprising a housing for assembly over the ends. The housing has an internal bracket with apertures aligned with a side aperture in the housing and positioned to be aligned with apertures in the outturned ends of the retaining ring to receive a locking member.The internal bracket retains the housing in position on the meter ring and prevents axial movement of the locking member and is so positioned that the outer end of the locking member when assembled, is spaced at or inside of the outer surface of the housing wall. A collar is assembled into the side aperture and extends outwardly therefrom. The collar is provided with apertures to allow a seal to be assembled across the collar over the end of the locking member disposed therein so that the seal must be broken to remove the locking member, and will provide evidence of attempts to remove the locking cover.

Abstract: A security seal formed of molded plastic which is particularly adaped for use with articles closed by staples and hasps, such as are used on a strap closing the neck of a mail bag. The seal components are arranged so that the loop formed by the assembled seal strap may be tightened to a predetermined dimension and no smaller, with the tightening tension not being applied to the point at which the seal is designed to rupture. A finger loop is provided which extends from the loop formed by the assembled seal in such a manner that when the finger loop is pulled, tension is applied directly to the designed rupture point to facilitate removal of the seal.

Abstract: A locking seal for use on doors of freight cars, trailer trucks and other large doors to prevent casual pilferage by non-professional thieves. In a first embodiment a length of steel cable is provided with means on each end for locking engagement with each other. In a second embodiment of the invention, a length of steel cable is provided with a stop on one end and the other end is provided with an assembly comprising a locking cap and means secured to the cable for receiving the locking cap in non-removable engagement. The locking means of either embodiment is adapted for rapid assembly without the use of special tools, yet the design of the two locking portions thereof gives the assembly a strength of engagement which is greater than the strength of the steel cable connecting the portions. The male portion of the locking means, when assembled, is completely enclosed within the female portion to protect the attachment of the cable to the male portion from physical damage.

Abstract: A seal especially adapted for use on a fire extinguisher or other device, said seal providing visual evidence of operability and has means to prevent operation of the device until the seal is removed. The seal is formed of a single piece of molded plastic and is provided with an integral finger loop to facilitate removal. In a preferred embodiment of the invention, the means preventing operation of the extinguisher is a rigid bar which extends through suitable locking apertures in the operating handle and handle support, and the seal means is a socket on one end of the bar and a shackle extending from the other end.
