Abstract: A piece of jewelry, like a ring, bracelet, or necklace containing a center opening, consists of a main body section which takes the shape of the piece. This section has a channel extending around its side walls into which arms from covers are inserted. The covers overlay the main body section and slidably move over the main body section by means of the arms in the channels. In the preferred embodiment, two covers are provided on the main body section, although one or more than two covers are contemplated. The two covers slidably move in opposite directions on the main body section. The covers may have decorative ornamentation on their outer surfaces. When they are placed together and locked into position by a spring detent, the jewelry has one appearance. When the covers are together, they also conceal and protect the gem, inscription, or other decorative ornamentation on the top surface of the main body section.

Abstract: A roller sponge mop which is used for routine floor surface or similar surface cleaning and moisture absorbing mopping is combined with an integral mop attachment with an outer abrasive surface, designed and formed to be positioned within a wall surface of the lower frame of the mop, to be used for cleaning more difficult and ingrained soiled surfaces. The attachment is removable and interchangeable for use on similarly configured roller mops. The sponge mop roller squeeze feature is actuated by a cammed lever which is rotatably connected to the mop's handle and is positioned adjacent to a sleeve slidable mounted on the handle. At its lower end, the sleeve comprises the frame which carries the mop attachment and connects to the mop's rollers. The bias action of a spring at the lower end of the handle maintains the sponge element of the mop in the cleaning position.

Abstract: A brushless slip ring includes a housing, a plurality of annular spaces disposed in the housing and spaced apart along a common longitudinal axis, and a cageless assembly of electrically conductive spherical balls freely rotatably disposed in each of the spaces. Each of the spaces is formed between radially inner and outer electrically conductive surfaces of a rotor and stator, respectively, and a pair of axially spaced retainer rings. The spherical balls conduct electrical current between the outer and inner surfaces. The balls are rigid and harder than the inner and outer surfaces and are arranged in an annular row. The balls occupy substantially the entire circumference of the space and are freely circumferentially movable relative to one another within the space for making contact with one another.

Abstract: Dual bonnet clips, preferably of integral plastic molded construction, are secured to the top surface of the head of a dust type mop. Each clip has two resilient upstanding arms which, when pushed down at their respective ends, causes the side sections of the clip to pivot up from the top surface of the mop at the clips' midpoint. In this raised position, the side surfaces of the mop's bonnet can be placed under the side sections. When the downward pressure on the ends of the arms is released, the side sections of the clips pivot down and lower onto the bonnet, securing the bonnet to the mop head.

Abstract: A mop with a cleaning head consisting of a plurality of fluid absorbent material strands connected to a handle. A wringer rod is connected at one end to a slideable, manually operated sleeve located around the handle. The rod is pivotally connected at its other end to a roller wringer. The roller wringer is of ringed or closed polygon configuration, taking its shape from a flexibly biased support member. The support member is preferably a solid rod formed in a rectangular or other polygonal shape. The support member passes through roller elements positioned one on each of the sides of the member and completely surrounding it. As the sleeve is manually pushed down the handle, the roller wringer is forced over the mop head strands, causing the support member and rollers to expand around the strands. The biased nature of the support member ultimately causes the rollers to compress the strands, squeezing the strands and moisture from them.

Abstract: A rotary contact push button electrical switch comprising a switch housing and separable independent base. The base is lockably connected to the housing by means of appropriately placed openings and tab means on the sides of the base. The housing has a through opening into which the switch's operating mechanism is disposed. A rotary contact with resilient arms forming arcuate contact points at the end of the arms is rotated by the operating mechanism, when the button which extends through the housing opening is pushed. A nipple at the end of the operating mechanism rotates the rotary contact. Stationary contacts which are mounted on the base, contact the arcuate points of the rotary contact, allowing electrical current to flow alternately between two separate electrical circuits, as the rotary contact is rotated over the stationary contacts.

Abstract: A snow shovel comprises a longitudinally elongated handle and a curved generally rectangular blade receiving an end of the handle on the convex surface of the blade. The blade is curved respecting a transverse axis and includes a scraper support edge extending transversely to the handle, defining a blade extremity remote from the handle. The blade further includes an upstanding lip on its periphery not defined by the scraping edge, extending transversely to the blade in the direction of the blade concave surface, with the portion of the lip being parallel to the handle, preferably being canted inwardly towards the handle. The blade further has upstanding triangularly configured reinforcing gussets formed in the blade and protruding from the blade concave surface, generally parallel with the handle, with the gussets having heights and widths at least initially increasing with distance from the scraping edge.

Abstract: A dustpan with a shovel section is configured in substantially the same shape as the broom head and is adapted, during non-use or storage, to overlay the head. The dustpan consists of a lower, open resilient tubular section which surrounds the handle of the broom. Shoulder members protruding from this section maintain the dustpan in position over the broom head. When the broom is to be used, the dustpan is simply slid up the handle towards the user, to a point where an outwardly extending rim at the lowermost end of the dustpan engages detents extending from a collar secured to the handle. The dustpan rim and collar detents interconnect, positioning and securing the dustpan on the handle to expose the bristles of the broom to allow sweeping. After sweeping is completed, the dustpan can be disengaged from the collar by sliding it down the handle, away from the user. It can then be removed from the broom to pick up dirt and debris.

Abstract: A water bottle holder for a bicycle which employs a flexible spring-operated cage with tension, that allows for the easy removal and replacement of the bottle by the rider, as well as in holding the bottle securely while retained in the cage during a ride. The mechanism is designed to remain safely operable even after multiple usages. The holder itself comprises a cage element with main and front support members. The cage element is mounted on the frame of a bicycle such that it is rotatable right and left, in a horizontal plane over and parallel to the frame. In this manner, the bottle retained in the holder may be easily removed for use during the ride, without loss of concentration or duress to the rider.

Abstract: A tube is combined with a biased drift pin arrangement, which combination is useful for locking functions in coupling and decoupling separate tubes, or in locking-hinged dustpans, and so on. The tube has a wall formed with a pair of holes. The drift pin is formed on a leaf spring that has a base portion and a cantilever portion joined to the base portion for relative flexion therebetween. It is the cantilever portion that is formed with the drift pin, as well as a spaced push pin. The leaf spring inserts in the tube such that the drift and push pins are aligned to extend and retract through respective ones of the pair of holes. To wedge the leaf spring in place, a separate cartridge is sized and shaped to permit sliding insertion in to where respective abutment surfaces of the leaf spring and cartridge, respectively, mate each other.

Abstract: The method of assembly of a mop head which includes a polymer carrier in the form of a channel with in-turned lips or barbs on opposed flanges that retain compressed mop material without the need for glue or the like. The method includes compressing a block of mop material between two surfaces to reduce its thickness and to stiffen it, and then driving the compressed mop material into the channel, whereupon expansion of the mop material engages the lips or barbs. The molded polymer carrier channel is relatively rigid and can have reinforcements to resist resilient opening of the channel. The extent of compression of the mop material is substantial, for example, by a factor of four or five during compression, and another factor of two when passing through the nip between the lips.

Abstract: A dual function locking bracket for holding and supporting the handle of a push broom or other hand cleaning push tool. The bracket is configured to support the handle in two different positions. For use in transporting and merchandising circumstances, the bracket holds and secures the handle close to the brush or cleaning head of the broom, with the longitudinal axis of the handle parallel to the length dimension or longitudinal axis of the cleaning head. The bracket can be readily removed and converted to retain the handle in a cleaning use mode. Use of the bracket in this manner forms an immovable connection which prevents the handle from coming loose from the cleaning head joint with the handle, supplies an extra measure of stability to the broom at its handle/cleaning head joint, and provides the handle additional strength to prevent handle breakage.

Abstract: A butterfly sponge mop which is used for routine surface cleaning and moisture absorbing mopping and an integral unitary mop scrubber attachment with an outer abrasive surface which is to be used on the head of the sponge mop for cleaning more difficult and ingrained soiled surfaces. The mop attachment consists of two detent tabs which are to be inserted into the existing cutouts located in the sponge support member of the mop. The attachment also has side holes for placement over the existing holes of the mop's support member, through which the ends of the mop's squeeze arms are inserted. The mop attachment is readily and easily removable from the sponge mop and is interchangeably designed to be used with existing or new butterfly sponge mops. In another embodiment the mop attachment and the mop's sponge support member is formed with the scrubber component as a single, molded plastic component.
