Abstract: A pre-formed structure, such as a shower stall, having three walls, each wall is comprised of a plurality of sheets of multiple, conjoined tile, having opposite finished and unfinished faces; binding materials such as adhesive, heating duct tape applied to the unfinished surfaces to conjoin the edges of the sheets of tile, and such materials similarly being applied to conjoin adjacent longitudinal edges of the walls; horizontal support members, composed of flexible material extending about the walls to interengage the sheets of tile and support them in position; vertical, rigid reinforcing elements extended upon each wall to help impart rigidity to the completed structure; a floor, or pan, preferably dimensioned to interengage with and be connected to the bottom marginal edge portions of said walls, and an upper wall preferably dimensioned to engage with and be connected to the upper marginal edge portions of said three walls.

Abstract: A manually shiftable transmission for use in automobiles with the usual driven shaft, axially aligned with a drive shaft. The usual gears, (for example, first, second, third, and fourth gear) are present on said shafts, to transmit a drive from any one gear to said driven shaft. Four sleeves, or driven members, are mounted by splines upon the main shaft and each is slidable thereon longitudinally of the shaft to pair with a gear. Each pair of driven member-and-gear has confronting lateral faces: on each said lateral face is formed one or more dogs to engage with the corresponding dog on a respective confronting face to transmit a drive from the gear to the driven member. The driven members are adapted for sliding travel by shifting forks between a neutral position and a drive position, in which the driven dogs on the driven member engage with the driving dogs on its companion gear.

Abstract: A locking member to block motion of the throttle valve lever, to prevent admission of gasoline to an internal combustion engine; means mounting the locking member upon the carburetor for travel between a throttle valve locking position and a release position; drive means to selectively urge the lock member in travel between the two positions; a housing mounted within the passenger compartment of the vehicle, and containing a locking assembly accessible to a driver to control the lock member; the locking assembly including a slide member slidable in reversible travel to actuate the drive member to urge the lock member in reciprocable travel between the throttle valve locking and release position.

Abstract: A small ball of desired size, to be pressed against the skin of a human patient in an area requiring therapy, is revolubly mounted in an end portion of a carrier which protrudes from a holder, with a portion of the carrier received in the holder for reciprocable sliding travel, therein, and a spring member carried in the holder to urge the carrier in one direction of reciprocable sliding travel, with the holder preferably carried by an elongated handle; the holder, and carrier being electrically conductive, and electrical circuitry carried by the handle and electrically connected to the holder whereby mild electrical current may be employed during therapy.

Abstract: A first length of insulated electrically conductive wire is immovably secured to one section of an extension ladder, and has an electrical outlet on such section of said ladder; a spring-loaded, self-winding storage unit secured to another section of the ladder, may releasably, windingly store a predetermined additional length of wire when said sections are in a normal non-extended position, such storage unit affording withdrawal of such additional length of wire when the ladder sections are moved to an extended position. Hooks are secured to the ladder sections, where desirable, to hang tools.

Abstract: A hollow body including spaced apart side walls, with a plurality of longitudinally spaced, laterally extending wall-support members surmounting a plurality of laterally spaced longitudinally extending floor reinforcement members. A track structure including a plurality of laterally disposed track structure support members projecting exteriorly of said walls in longitudinal alignment with, and secured to, said wall-support members. Said track structure further including an upper fixed runway and, substantially parallel thereto, a lower fixed runway, both elongated longitudinally of the vehicle. A supplementary runway surmounting said upper, fixed runway. Means to secure said supplementary runway above said upper, fixed runway. Means urging said supplementary runway toward said upper, fixed runway, and means adjustably resisting said urge, to space said supplementary runway from said upper, fixed runway. An endless chain drive, and means to drive said chain.

Abstract: A locating device for transmitting a mild electrical direct current or pulsating direct current through the body of a patient to locate through increased resistance, as indicated on the meter, areas in the body that may benefit from the application of an acupuncture needle. The locating device has an elongated handle with the necessary electrical connection. At one end portion of the handle a transversely formed hole receives an elongated, tubular, electrically conductive needle support and guide. Acupuncture needles are very thin and flexible, and require support to obtain best usage thereof. A restraint, formed of a resiliently yieldable strip of metal or wire extends across one end of the tubular guide and is disposed thereon to frictionally engage a needle to resist travel of the needle downwardly through the tubular guide.

Abstract: A carrier for inflatable pneumatic tires is supported for tilting travel about a substantially vertical axis upon an arcuately spherical universal pivot resting upon a seat having a corresponding sphericity. The seat surmounts a pedestal, and the pedestal and carrier are jointly formed with an air conducting means, the continuity of which is interruptible, to admit air to and from a tire mounted for balancing upon the carrier, to inflate and deflate such tire. The pedestal surmounts a fluid motor provided with two pistons in tandem: one piston carries an actuating rod to operate a valve to admit air to a tire prior to balancing, and to resist escape of air from an inflated tire on the carrier during balancing. The carrier is equipped with a lower rim element to engage a lower bead of a tire and an upper rim element to engage an upper bead of a tire. The upper rim element is removable.

Abstract: Ejector pins are carried by an ejector device, and are releasably secured in said device by latch means. Release of the ejector pins by said latch affords withdrawal, or replacement, or redistribution of said pins through a mold support plate, without removal of the ejector device from the molding machine assembly. A plurality of holes in the support plate coincides in number and distribution with a plurality of sockets in a carriage plate in the ejector device, to afford alternative groupings of ejector pins to accommodate various mold contours of interchangeable mold plates.
