Abstract: A lamp shade assembly kit includes an assembly ring formed of flexible material into a closed loop, a hoop formed of rigid material and a cover member formed of flexible material into a continuous, open-ended configuration. The assembly ring has an enlarged hoop-receiving channel opening inwardly about the periphery thereof. The cover member is adapted to be secured to the assembly ring. The hoop can then be inserted into the enlarged channel in the assembly ring to give a selected shape to the assembly ring and cover member. With these features, the lamp shade assembly kit may be shipped and stored in knockdown condition and quickly assembled without tools in any of a wide variety of shapes and sizes with optional decorative trim selections.

Abstract: A lockable closure for a container having an annular lip advantageously has locking means whereby the closure can be releasably locked to the container. The closure has at least an annular portion adapted to be disposed in contact with a portion of the annular lip of the container, and preferably also an annular wall adapted to contact a portion of a wall of the container to provide a sealing engagement therewith. The locking means generally comprises shoulder means for lockingly engaging the annular lip of the container and bending means adjacent the shoulder means for deflecting the shoulder means about the annular lip of the container. The closure is useful with containers formed of various materials, for example, of both metal and molded plastic.

Abstract: A one-piece bail for a container having an annular shoulder has a sleeve adapted to be placed about the container and abut the shoulder, first reinforcing means integral with the sleeve for reinforcing the sleeve, second reinforcing means for retaining the disposition between the sleeve and the first reinforcing means, tab means extending from approximately diametrically opposed portions of the first reinforcing means for providing areas of attachment, and a bail portion integral and pivotable with respect to the tab means normally disposed substantially concentrically with the first reinforcing means. The bail is independent of the manufacture of the container and is further independent of any interlocking action of the rim and closure of the container.

Abstract: A lampshade which is shipped and/or stored in a knock-down condition can be readily erected without tools into a shade which is as structurally sound as if manufactured in preassembled condition. The shade is formed of two ring members, one having a spider member affixed thereto; a plurality of rib members; a plurality of clamping members having means for releasably securing clamping member to a rib member and a ring member, and hence the latter to each other; and a lamp shade frame cover adapted to be placed about the other members in the assembled condition.

Abstract: A lockable closure for a container having a foldable annular wall advantageously has locking means whereby the closure can be releasably locked to the container. The closure has an annular bendable wall adapted to be disposed at least partially in contact with the annular wall of the container. The bendable wall has a reversely bent annular lip adapted to be disposed about the outer edge of the annular wall of the container. Upon the closure being disposed with its reversely bent annular lip disposed about the outer edge of the wall of the container, the bendable wall of the closure and its annular lip are deflectable with the foldable wall of the container to fold the bendable wall into and out of locking engagement with the foldable wall of the container. The closure is retained in either the locked or unlocked positions without additional forces or apparatus as it is substantially in a zero stress condition at these positions.

Abstract: A foldable wheelchair having shiftable driving wheels so arranged, that as the side frame members are folded to reduce the width of the chair, the wheels are controllably and automatically shifted to reduce the depth of the chair thereby effecting a reduction in the side area required to accommodate the chair.

Abstract: A metal ladder is fabricated from a pair of spaced rails in which the rails have web portions which are provided at spaced intervals with inwardly directed embossments. Each of these embossments has an opening into which one end of a tubular rung is inserted and swaged to the rail. The embossments act as ribs to carry the load toward the flanges constituting the stiffer portions of the rail thereby increasing the strength and effectively reducing the web flexure and angle changes between the rungs and the rails, due to sideward forces in ladder use. By reason of the built in stiffness web thickness may be reduced resulting in savings in materials. Additionally, intermediate these embossments, just described, the web portion of each rail is formed with one or more outwardly directed embossments.

Abstract: A mixer for mixing flowable material in a container rotates the material continuously in one direction about a first axis and simultaneously about a second axis which is non-perpendicular to the first axis, the first axis rotating about the second axis. The mixer has means for supporting the container and for rotating the container simultaneously about the two axes. Desirable top to bottom circulation of material within the container is attained by the mixer of the present invention, while the apparatus is simplified and provides economies due to its lower speed and unidirectional, continuous rotational operation.

Abstract: A combination bed and lounge assembly formed of three bed units of different heights. The bed units are adapted to be arranged so as to serve as a three tiered lounge appropriate for daytime use and to be moved apart in separated relation to serve as three separate bed units appropriate for nighttime use.

Abstract: A reclining chair adapted to be positioned in close adjacency to a wall, the chair having a frame and a body supporting unit which is movable relative to the frame between an upright sitting position and a variety of reclining positions. The frame is supported on ground engaging rollers and on rocker feet, the latter being connected by linkage arrangements to the body support unit. When the occupant moves the body supporting unit to reclining position both the chair frame and body supporting unit are caused to be moved away from the wall so that no part of the chair is in physical contact with the wall. Substantially 40% of the movement away from or toward the wall is effected by the body supporting unit and substantially 60% of the movement is effected by the frame. Upon movement to upright position the chair frame and body supporting unit return to the original position in close adjacency to the wall.

Abstract: A conventional single element IBM correcting SELECTRIC typewriter having an error correction system is modified by adding to the element a universal obliterating type font and providing an error correcting key function which is independent of the other keys.In the SELECTRIC typewriter the error correcting key is operatively connected with the backspace key so that activation of the error correcting key simultaneously activates the backspace key.

Abstract: A typewriter and the like utilized as an instructional aid device has control means for teaching alphabetical letter recognition, the sequence of letters in forming words and the association of a word to the picture of an object. A coded card, the preferred control means, carries the word related to the object, and optionally the picture of the object, and includes a series of perforations related to the word, which perforations are adapted to be penetrated by attachments carried on the key bars only when a key is struck in proper sequence. If an incorrect key is struck the device does not function. Card advancing means are provided to advance the card after each correct key is struck in proper sequence. In the absence of a control card, the typewriter and the like can be operated in a conventional manner.

Abstract: A carrier formed of welded rod or tubular metal and mountable on a conventional bicycle above the rear wheel to provide a rigid platform for supporting items of luggage and the like. A child's seat of molded plastic material includes simple means for detachably securing the seat to the carrier so that the device may be selectively used for carrying a child or luggage.
