A pilot tip 38 on the working end 26 extends axially from the "fishtail" cutting section 32 and is formed with a split point having leading cutting edges 40 and 42 and minor cutting lips 46 and 48. Outer surfaces 58 and 60 of pilot tip 38 are each formed with a radial relief and a back taper and joins with cutting section 32 along fillets 92 and 100 which are also radially relieved.

Abstract: The improved screwdriver bit and finder system of the present invention substantially aligns the axis of a screwdriver bit with the axis of a slotted-head fastener and maintains the alignment while the fastener is being driven. The inside diameter of a cylindrical finder and the diameter of a cylindrical driver portion and blade formed on an end of the bit are substantially matched in four different systems, with four discrete ranges of fastener head diameters. These matched systems of the present invention minimize the problems generated by conventional "one size fits all" bit and finders, namely, bit "wobble" in the finder and misalignment of the bit axis with the fastener axis, resulting in damaged bits and fasteners. In contrast, the axial alignment produced by the bit and finder system of the present invention minimizes the amount of driving force required and saves bits and fasteners from damage.

Abstract: A modified Phillips-type screwdriver bit is disclosed that is fully compatible with a standard Phillips-head fastener, and is designed to significantly increase the level of torque that can be applied to the fastener while at the same time substantially reducing the cam-out forces normally produced by a standard Phillips screwdriver bit. These results are accomplished by forming generated surfaces along the side walls of the bit wings so that when the bit is initially inserted into a standard Phillips-head fastener, lines of contact occur between the bit and recess adjacent and parallel to the roots of the bit wings. In this manner, the application of torque is confined to the sides of the bit wings even as applied torque levels increase.

Abstract: A cord caddy for carrying or storing a dispensable length of cord wherein the cord caddy includes a multi-layered reel disposed within an open-faced pan shaped housing. The cord or other flexible member will be coiled about the reel in upper and lower chambers thereof so as to be unwound (dispensed) therefrom whenever it is desired to use the extension cord. The reel will be free to oscillate within the housing during the dispensing of the cord therefrom. A cord stake will fix one free end of the cord while the opposite end is pulled so that during oscillation of the reel within the housing the housing will partake of the sliding translatory motion along the ground a distance that amounts to one-half of the total length of the cord exiting from the housing. The cord is free to rotate within the housing during the dispensing of the cord therefrom.

The gear reduction arrangement provides for a gear case cover having a support position for a pinion and a plurality of support positions for the idler gear. The idler gear support positions are placed at varying distances from the pinion gear position to accommodate pinion gears of various sizes and numbers of teeth, thereby to permit the tool to be operated at a plurality of gear reduction ratios.

Abstract: An elongated stamped sheet-metal slider member facilitates the alinement and support for the guiding pulley of a band saw. The slider member has several integrally-formed portions. A first portion depends within the housing, and the pulley is rotatably supported thereon about an axis substantially perpendicular thereto. A second portion of the slider member is bent away, forming an obtuse angle with the first portion, and extends through a slotted opening formed in the housing. This second portion has a pair of ears projecting laterally of the slotted opening for preventing the slider from passing completely into the housing. The ears have respective side edge portions engaging the outer surface of the housing and forming therebetween a fulcrum for pivotal movement of the slider member and hence the pulley about an axis which is above the pulley axis and transverse thereto. A jack screw is carried by the housing for engaging the first portion of the slider member below the pulley axis.
