Abstract: A granulator which has a rotor knife seat having a plurality of tapped holes and a clamp to secure a knife to the rotor seat, is set forth. The granulator further includes a floor formed in the rotor seat and a trapezoidal shaped knife having a rear wall. The knife has an upper surface and a forward sloping surface, the sloping surface terminating at one end in a cutting edge and intersecting at its other end the upper surface and defining at said intersection a knife alignment edge. An adjustable clamp having a plurality of bolt holes is also provided. The clamp may be moved with reference to the rotor seat within the limits defined by the diameters of the bolt holes.

Abstract: A granulator knife having opposed reversible cutting edges. The knife is seated in a rotor or a bed and secured by a clamp. When the first knife edge is worn, the knife may be reversed. Adjustment of the knife position is not necessary.

Abstract: This invention pertains to a protector ladder support used in pairs and removably mountable on stiles of a ladder. These protectors have non-slip resilient face portions adapted to engage the means against which the ladder is leaned. These supports have formed slots sized and shaped to receive and retain the rungs of a ladder. These supports have retaining members so that the protectors may be mounted and retained in a selected position. Conventionally, each protector is of sheet metal and the slots are usually at about thirty degrees and have a selected retaining means adapted to engage a rung of a ladder to retain the protector on the ladder stile. In one embodiment a pin or rod is disposed to engage a rung. In yet another embodiment a pivoted hook is disposed to engage a rung of a ladder and in yet a third embodiment a pivoted tab having a sloped engaging edge is adapted to be swung into a retaining condition and position.

Abstract: There is disclosed point-of-use apparatus that is actuated by a pair of socket wrench handles. This device allows one man working in a confined area, such as a cabinet or junction box, to bend tubing, pipe or cable; pull cable or rope or cut soft cable or rope on a job location without the assistance of a co-worker and providing a high degree of accuracy. This device provides apparatus for bending pipe or cable or may be used for pulling cable. This apparatus includes end plates that are spaced a determined distance from each other by means of connecting rods. The rods may also carry bushings for bending cable, pipe, tubing or thin walled conduit to a specific diameter. The second apparatus is designed to cut soft cable, tubing, rope and the like and is also actuated by the same or a like socket wrench handle.

Abstract: This application provides an attachable non-slip ladder support for and on an upper rung of a ladder with a typical stile and rung construction. This support has a shell-like member having an internal configuration which is sized and adapted for slidable mounting on this upper rung. Intermediate this shell-like member and fixedly secured to its outer surface is a resilient non-skid member which is typically of sponge-like material. This member is secured by adhesive, rivets or the like. Clamp members are used at each end of this resilient support to removably secure the support assembly to the rung in the selected desired attitude. These clamp members insure that the support is not moved during use so that the resilient portion protrudes ahead of the stiles.

Abstract: The apparatus for producing a desired quantity of ozone uses a flow of air in which a corona discharge utilizes high voltage to produce sparks. This apparatus includes a source of high voltage and the spark is produced when metal or conducting edge portions of the blades are moved in way of spaced conductors carried in a tubular confine. The blades are carried as an assembly which may be rotated by a flow of air. The flow of air and the turning of the assembly maintains the blades in a cooled condition so that unwanted burning of the edges of the blades does not occur. The corona discharged ozone may be used in swimming pools, or as an air purifier or dust eliminator. The ozone, when used in a closed building, will utilize a timer so an excess of ozone is not produced. The rotating of the bladed member is preferably by the flow of air, said volume of air flow regulates the speed of rotation.

Abstract: This invention pertains to the use of a hand-held hydraulic apparatus which uses hand operated or a small motor for actuating a hydraulic cylinder to move a piston rod to actuate particular attachments and apparatus. This apparatus includes apparatus to expand a tube; remove or insert a bearing either internally or externally; pull a wheel drum; cut lengthwise a race of a bearing; a quick-adjusting hydraulic jack; a knock-out with cutter; a shear; a press and a wheel puller.

Abstract: There are three different point-of-use apparatus that are adapted to be actuated by a socket wrench handle or handles. The first apparatus includes two like jaw member assemblies that have spaced apart substantially parallel upper and lower jaws connected to an end member which has a receiving socket for a wrench handle. The upper jaw is beveled at forty-five degrees so that when a strip of metal is mounted in facing jaw members the strip may be bent by the wrench handles to a desired angle. Another apparatus is for bending or pulling cable or tubing and includes end plates and connecting rods. The rods may utilize bushings for bending to a specific diameter. A third is for cutting of the cable or tubing and includes a scissors-type cutter with one handle removed and driven by a ratchet wrench.
