Safety retracting mechanism for the lower guard of a portable saw

Abstract: A manually operable actuator is connected to the lower guard retracting linkage by a releasable mechanism. Movement of the actuator causes swinging movement of the lower guard to its open position. Continued swinging movement of the lower guard to its open position as a result of being engaged by the work operates the releasable mechanism to disconnect the actuator from the lower guard, whereby spring means will automatically swing the lower guard to its closed position upon removal of the saw from the work irrespective of the position of the actuator. Return movement of the actuator to its closed position resets the releasable mechanism.

Tabbed eccentric locking device

A keeper is attached to a first door element, and a hasp is attached to a second door element and has a shackle guard that prevents a cutting device from engaging a shackle of a padlock connecting the keeper and hasp. A lock guard is attached to the first door element beneath the keeper and protects the case of said padlock.

Latch bolt guard

Abstract: A horizontally swinging conventional-type door has the usual openable and closable jamb confronting edge provided with a customarily beveled projectable and retractable knob-operated latch bolt. The portion of the latch bolt proximal to the edge beyond which it projects is provided with tamperresisting means, more particularly, diametrically opposite keeper notches. The notched portion of the latch serves to accommodate a manually applicable and removable jimmy-proofing guard which is bodily attachable and detachable and is, after the door is latched, applied from the room side. This guard has means which is releasably and retentively connectible with the keeper notches in a manner to positively secure the latch bolt in a non-retractable bolt setting and latching position. The guard has a handle which makes it readily applicable and removable.

Centralized security system employing a magnetic checking device

Abstract: A replacement for the watchman''s clock and key system employed by security guards to verify that security tours are properly made. In this new system, the guard carries a card with magnetizable rods in it instead of the watchman''s clock. He then proceeds to a number of checking stations along the route of his security tour where, instead of the key which is inserted into the watchman''s clock, there are a number of boxes into which the magnetizable card is inserted. These boxes contain magnets which may or may not effect the magnetization of the bars in the card. When the tour is completed the guard inserts the card into a reporting station where the magnetic card is checked. If the security tour has been made properly the right rods will be magnetized in a particular manner by the magnets in the boxes and the checking station will send a signal to a central recording station to indicate completion of a properly executed tour. If the tour was not properly made and the proper bars magnetized, no such signal is sent to the recording station and the guard is told so. The guard must then report into the central location or repeat the round.

Padlock body affixed shackle enveloping guard

Abstract: To provide a metallic protector for substantially enveloping the major exposed portion of a retracted and locked padlock shackle an eccentrically shaped guard is affixed to the end portion of the padlock body in covering relation to the normally exposed portion of the shackle. The outer end of the guard is slotted so that when the shackle is unlocked and reciprocated outwardly for staple eye engaging or releasing purposes, it will freely move outwardly through the slotted end of the guard while the guard remains immovably affixed to the padlock body.

Guard-rail assembly with pivotal support posts

Abstract: A guard rail formed of a downwardly open channel whose interior is filled with a bonded-in-place synthetic-resin mass is formed approximately every 10 meters with a downwardly open pocket in which the upper end of a support post is received. A pivot bolt transverse to the rail passes through the rail and the post and allows pivoting of this post relative to the rail in a horizontal plane including the rail. The lower end of the post is received in an upwardly open channel so that on collision of a vehicle with the post or a similar blow being struck to the post below the rail, this post will pivot out of its socket and up into the pocket so that the rail itself will take the blow to prevent a vehicle from flipping over the guard rail.

Safety pin with pin point guard for preventing manual removal of said point from said guard

Abstract: A special destructable or non-destructable safety pin is employed to mechanically couple a sensitized tag to an item to be protected against shoplifting. If a shoplifter carries the protected item through an exit area with the sensitized tag on the item, an alarm device will alert store personnel to apprehend or photograph the shoplifter. A sensitized tag is rapidly and easily applied strictly by hand to the protected garment by means of the special safety pin which upon being closed annot be opened except by special devices at the cashier''s station. Once the safety pin is closed, it cannot be opened by a shoplifter without cutting the pin portion which is made difficult, at least for the average shoplifter, because the pin portion is case hardened by well-known techniques; also shoplifters, particularly a large number of females, would be reluctant to use wire cutters, carry them about and be caught with them. Additionally, the special safety pin may be employed to attach ordinary price tags to the goods and would thwart price tag switching.
