Abstract: A set of goggles comprising a lens holder including a pair of confronting straps having aligned lens apertures therein which receive lens. The straps are coupled together along the bottom, side and outer top confronting edges but are separated at a central, upper passage which is wider than the width of each lens but narrower than twice the width of each lens. Mechanism is provided for detachably coupling the lens holder to headgear, such as a helmet or a bandanna, and includes side bands that are coupled to opposite ends of the straps and extend along the sides of the head of a user. The bands can be detachably coupled to complementally formed fasteners provided on the helmet or bandanna. The side bands include forward portions folded over upon themselves and coupled to the ends of the straps.

Abstract: An archery aid for improving shooting accuracy of an arrow propelled by an archery bow having a taut bow string spanning opposite ends of the bow. The archery aid includes a plate mounted on the bow adjacent the hand rest against which a forward archer's bow hand bears when the bow is being drawn. The plate extends in the path of the fingers of the archer's bow hand to prevent the fingers from gripping the bow during and after string and arrow release. A finger receiving member is mounted on the plate for detachably securing the fingers to the plate.

Abstract: Jaw slide apparatus for releasably holding relatively moveable frame bars of a collapsible and extensible frame, such a convertible top boat frame in spaced apart positions. The jaw slide includes a slide bushing received on one of the frame bars for axial sliding movement thereon as the bars are moved toward and away from each other. A bearing mounts on the slide bushing for rotation relative thereto as the bushing slides along the bar.

Abstract: A method of decorating concrete including the steps of mixing water, aggregate and cement to provide mortar, pouring the mortar into a form and allowing it to cure and harden into a concrete block having an exterior surface, and applying sulfate to a selected portion of the block to color the surface of the block to a predetermined depth while the mortar is being cured.

Abstract: A roller blade wheel caddy including a plurality of stations for individually storing a plurality of disassembled roller blade wheel assemblies each including a roller blade wheel, a pair of roller blade bearings for rotatably mounting the wheel on a shaft, and a tubular bearing spacer for axially spacing the bearings on the shaft. Each of the stations includes a wheel well of a predetermined magnitude for receiving a wheel, an associated wheel bearing well which has a substantially reduced magnitude, and an associated spacer storage member for storing the spacer associated with the wheel. Indicia is provided for indicating a predetermined rotational sequence for the roller blade assemblies. A wheel assembly peg is provided for use in assembling the parts and a storage well is also provided for storing miscellaneous parts.

Abstract: An inflatable and deflatable support for a sign having advertising indicia thereon including an air inflatable, cylindrical member having an upper, inflatable, cylindrical cross member spanning a pair of upstanding inflatable legs which depend from opposite ends thereof. The legs are each open at the lower end and are sealed to a hollow cylindrical ballast plug. Mechanism is coupled to one of the legs and cylinders for admitting air under pressure to the cylindrical ballast plug to inflate and deflate the cylinder.

Abstract: Tube flaring apparatus for forming a radially outwardly extending flange at one end of a hollow malleable cylindrical conduit including a rotating spindle journaled on a stationary housing and mounting a chuck at one end thereof. The chuck cantileverly supports an axially extending conduit to be flared. A flaring tool is mounted for movement between an axially outer radially inner position removed from the conduit and an axially inner, radially outer position bearing against the inner surface of the outer end of the conduit to radially and axially displace the end to form a flange. The flaring tool is coupled to a piston rod axially driven by a fluid operated cylinder which is mounted in fixed relation relative to the chuck at the axially opposite end of the rotating spindle.

Abstract: Seed bed preparation apparatus for the no-till preparation of longitudinal strips of soil for the planting of seeds in longitudinal rows including plurality of laterally spaced apart gang assemblies which are individually mounted on a draft vehicle such as a tractor or the like. Each gang assembly includes a main frame, adapted to the coupled to the draft vehicle, swingably mounting a chassis which follows the contour of the land via rotatable depth wheels which mount a forward, surface soil cutting disk for cutting a slot in the surface soil. A vertical tillage blade is received in the slot cut by the cutting wheel and includes an under surface soil lifting tillage point for lifting and partially breaking up strip of soil as the apparatus forwardly moves. A pair of rotatable soil crumbling disks are mounted on the chassis, parallel to the tillage blade, on opposite side of the blade for containing and further crumbling the portion of the lifted strip of soil between the disks and the blade.

Abstract: Apparatus for differential pressure forming an article in a thermoplastic sheet including a female mold cavity mounting a one piece, ring-shaped detachable mold insert for forming at least a portion of the article. The insert is formed by rolling a crescent shaped sheet, having opposite ends into a truncated cone with opposite ends thereof in abutting relation, inserting the truncated cone shaped mold insert into a mold cavity, and applying endwise force to the ends of the mold insert to detachably secure the mold in a mold body.

Abstract: Apparatus for maintaining the quality of lubricant and level of lubricant in an internal combustion engine without having to remove lubricant. The oil pan or crank case normally mounted on the underside of an internal combustion engine is modified to include a deep well in the lower wall thereof which has a breadth substantially less than the breadth of the oil pan so that a substantially reduce volume of oil is required to safely operate the engine. Apparatus is also provided for supplying make-up lubricant to the engine while the engine is operating and includes an air impervious reservoir containing make-up lubricant. A conduit is coupled to the lower end of the reservoir and is received in the deep well. The conduit includes a lower end having a discharge opening disposed at the level of lubricant in the well when the engine is operating.

Abstract: A stud for snowmobiles and the like including an elongate shank and an integral, transversely disposed head. The shank may be mounted in an aperture provided in an endless snowmobile drive track with the head engaging one side of the snowmobile track. A fastener is detachably mounted on the shank for engaging the opposite side of the track. The head includes a concavo-convex flange having a concave inner surface for radially inwardly urging a portion of the track which is adjacent the shank and which is axially displaced when the head is mounted on the track. The head also includes an axially outer surface having an axially inwardly extending, central recess having a radius of curvature which matches the radius of the snowmobile track drive wheels.

Abstract: An enclosure for a conventional bird feeder having top and bottom portions pivotally secured to a suitable top or bottom support. A shroud extends about the sides and back of the enclosure and includes a front opening for ingress and egress of birds to and from a bird feeder which is disposed within the enclosure. A perch comprising a wall extends from the bottom portion beneath the opening. A weather vane is attached to the enclosure for rotating the enclosure to a position in which the opening is away from the force of the wind to protect the partially enclosed bird feeder from the elements while providing access for birds entering and leaving the enclosure.
