Abstract: This manufacture prevents an unauthorized removal of an article or equipment item, such as a typewriter, for example, from a table top or the like. The article is secured to a cover plate which includes a plurality of hooking members or ears on its underside. These hooking members in turn engage apertures the body formations for which are securely mounted to a flat plate that in turn is secured to the table top or mounting surface. To assemble cover and plate into a locked position, the cover and its ears are shifted in a direction for engagement of ears to apertures. In this position then, a tang on a cylinder lock mounted in the cover's periphery is rotated into abutment with an edge of the plate, and the lock locked. The cover can no longer shift in a reverse direction to disengage ears from apertures. Case-hardened sleeves are provided to prevent sawing of screws which secure cover and article together.
Abstract: A gimbal assembly mounted in a housing, particularly in a laser beam manipulator, by which the change of direction for a reflected beam or the like is measured in a second of a degree-of-arc in motion. An element such as a specular one including a mirror is mounted within a gimbal ring subassembly, the compound or universal motion of which is actuated by a member such as a shaft that is operatively connected to a swivable member mounted in a structural frame member. Such operative connection provides for the same change in direction for the laser beam as the change of direction of movement for means controlling the swivel element. Or, the actuating member can be fixed to the swivel member by which the element moves in a direction opposite to the direction of movement for the controlling means (joystick). Means are provided to apply pressure to and on the swivel member to thereby ease or make difficult the manipulation of the joystick, depending on the desire of the operator.
Abstract: A hand tool, such as a shovel, having unique working head or blade and shank elements. The blade includes a dished panel transversely disposed from its longitudinal axis and flaring from rear to working end. The trough of the blade is shallower at its distal or working end than at its rear end at which the shank is secured such as by welding. The shank is of a single-walled tubular construction and includes a cut, pinched, angled end which is welded to the rear of the blade, a buckled, curved portion extending from such securement to a straight portion integrally continuing from such buckled and curved portion, to an expanded hub swedged contiguous to the other end of the shank. A tapered handle fits to and through such hub, secured by a rivet to the shank. A plane of symmetry extends throughout the tool. The invention includes method for forming tool, blade, and shank.
Abstract: Top jaw assemblies combined with a chuck. Each of these top jaw assemblies comprises a body having a base projecting radially inwardly when mounted to the chuck, a cylindrical wall in the body which with the base provides a cutout portion and in which a workable rotatable workpiece gripping member or "slug" is mounted and secured to the base. The slug's periphery or annular wall conforms to and engages the cylindrical wall and includes an opening having a counterbored hole in which a screw mounts and extends below the slug to thread to a threaded aperture in the base. The slugs are machinable to provide different gripping surfaces contoured to the configuration of different workpieces, and are rotatable to provide the necessary reset position for such gripping surfaces in relation to the different sized workpieces. The base can be slightly inclined so as to force the slug's diameter against the matching radius of the cylindrical wall when the slug is torqued to the base.

Chamfers along the split are provided.
Abstract: This invention is found in the construction or configuration of the elements in the head of a driver apparatus utilized in securing screws in wooden members and to its relationship with a wire magazine loader mounted to the driving apparatus itself. The invention comprises a head member having a top and an outer wall which encompasses a cavity that forms crossed passageways extending to the top, openings in the outer wall communicating with cavity, atmosphere and magazine loader. The first of such cavity passageways is formed by vertically-oriented walls and a bottom, for containing an eyelet screw. A bar is provided at the bottom, in alignment with the first passageway for supporting the screw eyelet to which a hanger wire is to be threaded.
Abstract: A droplight tool accessory which produces a universality of position for the droplight, resulting in full intensity of illumination and reflection of light in the direction toward point of work. The accessory comprises three flexible arms between two of which an opening is provided and through which the droplight's handle is inserted so as to be clamped by lines of support included in the arms. Means to hand and rotate the accessory are included, as well as spaced points of support to seat the accessory and clamped droplight on a support surface.
Abstract: A mechanism which greatly reduces the number of components to be manufactured and assembled, and incorporates a kinetic energy storage system into a printing arm-stylus arrangement, and by which incorporation, stored or resilient energy is utilized to provide the stylus with an initial velocity greater than zero with rebounding from impaction with a surface or the like. An auxiliary mass is resiliently or spring-related to the stylus on the one hand, and resiliently or spring-related to a cantilevered beam on the other hand. The printing arm and stylus are caused to rotate towards and from an impacting surface by means of a torque produced about a point of rotation for the stylus. A motive source of force, such as armature and electromagnet, pulls and pushes a tension means or rod disposed at a constant radius from such point of rotation, such means operatively connected to the printing arm and stylus. Superior performance in terms of speed of and time saved in motion of the stylus is achieved.
Abstract: A surgical instrument comprising a pair of co-axially assembled tubes having their distal walls in bearing relationship and with registrable openings extending through such distal end and annular walls correspondingly joined to their respective distal walls. The inner tube reversibly rotates within its matched outer tube in operation of the invention, as action by cutting edges formed about such openings severs tissue drawn into the inner tube by suction. Each distal end wall includes a pair of circular cutting edges, those in the inner tube having a straight cut across its thickness while those in the outer tube have a full radiused cut across its thickness. Full radiused cuts across the thicknesses of the annular walls of the inner and outer tubes are provided for arcuately-formed and parallel cutting edges forming the respective openings in these tubes in their annular walls. A method to form these openings by means of these cutting edges is disclosed.
Abstract: A seal assembly for an enclosure, which attenuates or eliminates frequencies through the enclosure, and including a non-magnetic electrical conducting membrane on a door frame to which the door seals. Also, means for opening the door from either of its sides which means do not cause any frequency leakage through the door in its closed mode. The membrane is formed in segments, one of which is contiguous to and engages a magnetic member disposed in a pocket formed in the door assembly. Other segments constitute resilient formations in the membrane and by which the magnetic member resiliently receives the door upon its engagement therewith.
