Abstract: A carpet cutter is disclosed which is used to cut any excess edges of a carpet to the size of a room after it has been laid in the room. The carpet is cut at its bend toward the wall. It includes a bed plate slid on the carpet, a guide plate at front of the bed plate to be pressed against the wall, a slanting blade mounting plate in the rear of the guide plate, a pair of blades mounted on the blade mounting plate, and a pair of presser rollers disposed outside of the blades for pressing down the carpet against the floor just before cutting. The carpet is cut by one blade slantly mounted so as for its edge to butt on the wall surface. The clamping nuts for the blades are tightened in reverse direction to each other. Therefore, there is no fear of the blade coming loose by contact with the carpet during cutting. The position of the presser rollers can be adjusted by means of one adjusting mechanism provided in the center according to the thickness of the carpet.

A lateral slot communicates with the opening for receiving a spoke and a crowned anvil is provided between the ends for hammering the weight in place against the rim without deforming the weight.

Abstract: A pruning saw having an arcuately shaped housing which guides a flexible saw blade as the blade moves back and forth within the housing. The saw blade is comprised of toothed blade segments, pivotally fastened together. Each segment has its teeth bent or set to produce a kerf which is greater in width than the width of the housing.

Abstract: A simple cutting device in two sections which closes against itself slicing at prearranged angles and depth sausages and hotdogs and the like placed therein producing a spiral cut in the hotdog or sausage the entire length of the unit.

Abstract: A tool is disclosed which removes an automobile ignition lock of the type having a keyway and opposed radial extending ears. The tool has an inner cylindrical core with opposed recesses along its sides which engage the ears of the lock and retain the core from turning. The core contains means for securing the core to the lock by insertion of a member, such as a screw, into the keyway of the lock. A hollow cylindrical housing fits over the core, and the forward edge of the housing bears against the lock enclosure or against a collor mounted around the lock enclosure if there is insufficient bearing surface on the enclosure. The lock removal is accomplished by means, such as a threaded rod and nut, for retracting the core into the hollow housing interior. The retracting core pulls the secured lock out of the lock enclosure. Removal of the lock is accomplished without the necessity of disassembling the steering column of the automobile.

Abstract: An improved speedometer cable housing release and removal tool for disconnecting a speedometer cable housing from the speedometer head of an automobile or the like. The tool has an elongated curved body portion or handle with a linear portion at one end of the handle and extends to form a combination fulcrum-guide that is disposed generally in a plane perpendicular to the handle. The combination fulcrum-guide has a bending radius along a cable housing receiving groove permitting the tool to straddle the speedometer cable housing, thereby permitting the speedometer cable housing to serve as a finder for the tool. A depressing arm is connected to and proceeds from the combination fulcrum-guide generally parallel to an axis extensive through the linear portion of the handle. The depressing arm is of adequate length to reach a release trigger which is attached to the speedometer cable housing.

Abstract: An improved nail clipper which contains upper and lower handles to facilitate holding the unit and maintaining it in the desired position. Comprising cutting jaws in three sides to allow nail clipping from different and more convenient angles. Also a clipping receptacle with removable lid which surrounds the unit and holds the clippings produced, therein.

Abstract: Knives including a cutting blade and one or more wider non-cutting runners projecting slightly beyond the cutting edge of the blade and preferably at both ends of the knife blade. The runners prevent scratching of a substrate on which the material, normally a comestible, is being cut. On each runner there is provided on either side a beveled ramp inclined toward the adjacent cutting surface which acts very much as a plowshare to push up the material being cut against the cutting blade. This prevents a thin strip of material which would otherwise not reach the cutting blade and is particularly important with comestibles such as meat, which are sufficiently tough to permit forming such a thin strip. Where knives are manufactured, the ramps or plowshares can be incorporated in the knife blade when it is manufactured. However, there is included the provision of attachable runners for knives which have already been made.

Abstract: An assembly tool for closed, self-locking retaining rings includes an extensible and retractable, tubular, centering sleeve for centering the ring on a ram recessed relative to the sleeve. The sleeve is carried by a housing in telescoping relationship with the ram. One end of the sleeve is fashioned with a plurality of circumferentially spaced guide slots bounded by circumferentially spaced rigid guide and centering fingers that are operable to center the ring by engagement with the ring body and to pilot the tool by engagement with the member to which the ring is to be assembled. Adjustable stops may control the position of the ring in an assembly in axial relationship to the parts of the assembly.

Abstract: A guide bar has a groove extending along the top and bottom edges and continues in a semi-circular path around the outer end. A cutting chain has drive tangs that slide in said groove to guide the cutting chain along the edges of the bar. A thin rigid plate is fixed to one or both sides of the guide bar near the outer end thereof and extends slightly past the outer end to form a safety rail that reduces the degree of hooking that is caused by the depth gauges and cutters of the cutting chain digging into or hooking onto a tree or branch being cut.

Abstract: A power-actuated de-horning system is provided wherein a guillotine-type blade is driven through the horn of an animal by means of a hydraulically-actuated cylinder and piston assembly.

Abstract: A reciprocating saw for cutting foam rubber having a blade with a pattern of no-set teeth interrupted at intervals by toothless arcuate grooves, and a guide member having a slotted, elongated, wedge-shaped section enclosing the portion of the blade rearward of the blade cutting section, and a base section connected to the slotted section for confining the material to be cut above the base and in the cutting region of the blade during the cutting operation.

Abstract: A blade receiver and a handle, having opposed abrasive surfaces, are connected by a screw and a nut whereby the screw and nut are operable to press the abrasive surfaces together. The blade receiver includes a chuck and collet where a blade of the knife is removeably retained.

Abstract: Disclosed herein is a hair clipper comprising an outer housing of electrically insulating material, a motor located in the housing and including a field structure, an armature structure including a shaft, and bearing assemblies spaced axially of the armature structure and engaging the armature structure and the field structure for supporting the armature structure for rotation relative to the field structure, each of said bearing assemblies including a bearing and a bearing sleeve fabricated of electrically insulating material and located to isolate the bearing from one of the armature structure and the field structure, and screws mounting the field structure from the outer housing.

Abstract: There is disclosed a tool comprising a body having an opening which may be moved over a nut threaded onto a bolt and a surface on the opening to support the flat side of the nut, a bore in the body connected at one end with the opening opposite the supporting surface, and a rod having a cutting edge longitudinally reciprocal within the bore toward and away from the nut in the opening. The rod is so reciprocated by an operating system which includes a piston on the rod reciprocable within a cylinder on the body connecting with the other end of the bore.
