Abstract: A lock for securing an automobile storage battery from being stolen when the vehicle is left unattended, the lock consisting of a pair of vertical bars which at their lower ends are hook shaped so to anchor through a tray upon which the battery is placed, the bars being positioned adjacent opposite sides of the battery so to retain the battery therebetween, and a crossbolt extending across the top of the battery being padlocked within the upper ends of the vertical bars.

Abstract: An improved metal stamped and formed screw is disclosed. The subject screw is stamped and formed from continuous web of metal stock to form a plurality of screws joined by a carrier strip. The thus formed strip of screws can be machine applied to prebored holes and manually withdrawn therefrom and reapplied by conventional means.

Abstract: In combination with a workpiece having a bore, a first counterbore, and a second counterbore which is frusto-conical and tapers forwardly between the first counterbore and the bore and toward the bore,(a) a rivet having an axially extending shank received in the workbore and defining an axis,(b) the rivet including a head having an end face, a first section located forwardly of said end face, and a second and forwardly tapered frusto-conical section located forwardly of the first section,(c) the first section having an initial undeformed outer surface of a diameter which is less than but about the same as the initial diameter of the first counterbore, the rivet first section being radially deformed to have peripheral engagement with the first counterbore,(d) said head end face being substantially flush with the work surface.

Abstract: A blind fastener assembly includes a pin, an expander and a sleeve. The pin and expander may include, in one configuration, mating threads for drawing the sleeve axially over the expander toward the blind side of a workpiece, or the pin may be a pull-type wherein the portion of the pin opposite from the blind side end has pull grooves which are adapted to be gripped by a conventional pull gun. The expander extends through aligned holes in the workpiece and has a tapered nose surface at the blind side end adjacent a reduced thickness cylindrical portion which extends axially to a stop shoulder. The shoulder provides a transition to a normal thickness cylindrical portion which extends through the workpiece holes. The sleeve is a tubular member with a portion of its length having a normal radial thickness and a portion having a reduced radial thickness.

Abstract: A cylinder lock, particularly a rolling gates cylinder lock, which may be mounted, at will, as a right or a left lock. The lock is provided with a sliding bolt which is guided for its movement into locking and unlocking position by a guide block housed inside of the lock casing. To the central portion of the sliding bolt a rack bar is secured, in mesh with the pinion operated by the cylinder of the lock. The said rack bar acts as an abutment member in cooperation with the lock casing in order to limit the sliding movement in both directions of the sliding bolt. Means are provided for fastening the said lock to a rolling gate by using nuts and bolts.

Abstract: A safe and tamper-resistant lock assembly for sliding glass doors and the like for securely locking a slidable door in a closed or partially opened position. The lock assembly includes a specially configured bracket which is mounted upon the stationary frame assembly of the door unit. The bracket has an inverted J-shaped channel and an elongated wall defining a plurality of apertures including one aperture which is positioned to overlie an aperture in the slidable frame of the door when the door is in a closed position and another aperture which is positioned to overlie the aperture in the slidable frame when the door is in a partially opened position. A specially configured locking key is provided with a cylindrical shank having an arcuate locking cam for lockably engaging the inverted J-shaped channel of the bracket when the shank is inserted into the aperture in the slidable frame and into one of the apertures in the bracket.

Abstract: An improved bicycle locking rack which comprises a pair of parallel sidewalls attached to a solid ground base between which the bicycle is placed. One side of the stall has attached thereto an adjustable locking bar which may be lowered against the frame and locked in place thereby holding the bicycle firmly on the ground between the sidewalls of the stall and effectively preventing removal of the bicycle or any of its expensive components.
