Abstract: A stage or other structure having support legs includes rollers which are mounted so as to be supporting the stage in a first position and having the stage legs support the stage in a second position. A lift mechanism includes actuating pedals near the ground for raising and lowering the assembly. A linkage pivots the roller mounting member between a raised and lowered position relative to a cross member on the frame. A second pedal is selectively engageable by a single foot for retaining the roller assembly in either the raised or lowered positions.

Abstract: A skirt system for caster wheels to prevent a rolling caster from colliding with floor debris. A skirt assembly is fastened to a caster having a swiveling housing in which is mounted a caster wheel on an axle. The skirt thus swivels with the caster. The skirt assembly includes a circular skirt housing fastenable to a caster housing and having a central opening through which the caster wheel extends. Skirt material, such as brush fibers, is secured in a split ring which is removably held to the skirt housing by ring spring tension. The skirt may extend entirely around the caster or a segment may be portioned in front of the caster wheel.

Abstract: A guard guide surface for the lift-off slot of a tilt sash shoe is disposed obliquely above the lift-off slot to engage the head of a sash pin rising directly vertically from the slot. This prevents accidental withdrawal of a sash pin from a shoe when the sash is tilted. When the sash is slanted, however, for intentional withdrawal from a window, the sash pins can be lifted from their slots in off-vertical motions that clear the guide surface.

Abstract: The present invention features a universal primary hand grip device for use with tools and utensils. The primary hand grip has multiple angles by which the hand can grip the shaft of a tool or utensil, thus making the grip ergonomically efficient. When used in combination with a secondary cross-handle, a tool or utensil can become quite easy to use and comfortable to operate. The primary hand grip device of this invention has a grip that slides over, or is made integral with, the end of the shaft of a tool or utensil. The hand grip has a multiply-angled surface, in which the primary hand can assume a substantially straight-angled position (180.degree. angle) with respect to the axis of the wrist. The correct hand position varies with each tool and with each work surface. The proper grip angle for a particular task allows the hand to maintain a straight angle with respect to the wrist axis, while also imparting the driving force of the arm into the shaft of the tool.

Abstract: A handle for a tool such as a lobby dustpan is provided. The handle is preferably mounted on a vertical shaft of the tool. The handle may be placed in either a locked position or an unlocked position. In the locked position the handle is rigidly connected to the shaft. In the unlocked position the handle moves freely with respect to the shaft.

Abstract: A releasable caster for use with a moveable structure having a bottom wall wherein the caster has a swivel connected yoke and stem with the yoke supporting a plastic wheel. The stem includes a manually operable spring biased rod that has an indentation between its ends and co-acts with a ball detent. A shell with a flange at its outer end is adapted to be received in an opening in the wall. The shell has an abutment, prefereably in the form of a groove with the upper edge forming an abutment which copperatively locks the ball detent or releases the ball when the rod is moved longitudinally or rotationally.

Abstract: A method of manufacturing a caster includes the step of integrally forming a caster horn having a web portion with a bearing cup and a pair of opposed leg portions. The web portion and the leg portion define a U-shaped, wheel-accomodating space. The bearing cup is disposed on a surface of the web portion opposite from the U-shaped wheel-accommodating space. A first end of a stem is then pressed into a bearing assembly such that the stem is vertically rotatable with respect to the caster horn. The bearing assembly is seated in the bearing cup. The bearing assembly may be secured to the bearing cup by means of a retainer and a plurality of fasteners. The fasteners engage the caster horn, covering the bearing cup while allowing access to a second end of the stem. A wheel is rotatably supported within the U-shaped wheel-accommodating space.

Abstract: Draw processing flat-rolled sheet metal substrate preselectively precoated on each surface with organic coating and draw lubricant into one-piece can bodies ready for assembly into sanitary can packs free of any requirement for applying organic coating or adding organic coating for repair purposes after fabrication and before such direct usage. Cupping of precoated flat-rolled sheet metal can stock using preselected tooling configurations and clearance avoids any increase in side wall metal thickness gage. Tension elongation during redraw is controlled over side wall height by clamping solely between planar clamping surfaces, tooling configurations and preselected clearances to decrease thickness gage uniformly over side wall height between flange metal open end of can body and curved transition zone at closed end. Surface area of the cavity entrance zone for each die is fabricated about multiple radii forming sharp edge about which coated can stock is drawn into each die cavity.

The sheath holding portion (11) is provided with a flange portion (11a) which contacts a coiled spring when mounted in a connector housing, and the core wire holding portion (12) includes a large-diameter portion (13) at a front end thereof for receiving a front end portion of the core wire portion (b) of the plastic fiber (A) softened by hot plate treatment. The large-diameter potion (13) has a tapered inner surface such that an inner diameter thereof increases toward the front end, and the angle of flare thereof is 30 degrees.

Abstract: A fastening element for fastening hardware elements (31) to parts of furniture units (14) comprises an expansion plug (11) having an axial through housing (17) which can receive an expanded pin (23), which can rotate between a position in which the plug is not expanded, to enable it to be inserted in a hole (16) in the furniture unit (14), and a position in which the plug is expanded to anchor it in the hole. The walls of the axial housing (17) and of the pin (23) have reciprocal contacting surfaces in the expanded position which diverge in the direction of insertion of the plug. A cam plate (32) provided centrally with a polygonal hole (33) for coupling with a protrusion (30) of the pin (23) and peripherally with a raised edge (34) for guiding fingers (22, 22') of the plug (11) for reversibly guiding the expansion of the plug.

A structure is for securing in a removable manner the block member against a leaf of a hinge on a doorjamb, so as to stop a door from closing completely into the doorjamb and preventing fingers of a hand of a person getting caught and damaged between an edge of the door and the doorjamb.

Abstract: A three diameter hinge pin for a vehicle door hinge assembly including a door bracket and a body pillar bracket. The three diameters include successive large upper diameter, small lower diameter, and an intermediate diameter, wherein the latter diameter permits the hinge pin to drop further downwardly through two openings in the upper legs of two hinge brackets, wherein the openings must closely approximate the pin's large upper diameter, thereby allowing the lower end of the pin to enter the opening in the lower legs of the two brackets, rather than being positioned somewhere above the opening.

Abstract: A rotary friction damper in a device for connecting a door to an adjacent structure such that the door pivots about an axis during opening and closing of the same and including a torsion spring operatively connected to the door and to the structure for movement about the pivot axis to store energy during opening of the door and to release energy to provide closing during closing of the door. The rotary friction damper is operatively associated with the torsion spring and has an axis of rotation disposed substantially parallel to the pivot axis for controlling the door closing speed. The rotary friction damper is adjustable and variable. A mechanism operatively associated with the damper varies the resistance of the damper to movement of the torsion spring to produce a controlled uniform closing speed of the door and for reducing the resistance of the damper to movement of the torsion spring when the door nears the closed position to allow the torsion spring to close the door in an unrestricted manner.
