Abstract: A drain for a prefabricated shower stall that can be quickly and easily connected to a drain pipe, even though the drain pipe might be off-center with respect to the shower drain opening. The drain consists of two interfitting parts, a first of which is a drain body designed for attachment to the shower stall, and the second of which is a bushing-like member designed to interconnect the drain body and drain pipe. The drain body has a round opening, with a converging wall, extending through it, and an outwardly extending flange by means of which it can be affixed to a prefabricated shower stall around the drain opening in the stall. The converging wall of the opening in the drain body serves as a seat for the second part of the drain, which has a frustoconical outer wall to make this possible. This second part has a cylindrical bore concentric with its outer wall and is of such size as to extend below the first part, when seated therein, and telescopically receive the drain pipe in its cylindrical bore.

Abstract: An inexpensive anti-theft control device for an ignition fired internal combustion engine comprising a resistor and settable switch connected in series between the interruptor circuit from the ignition coil and ground whereby, when the switch is closed, a portion of the current normally necessary to induce sufficient voltage in the coil to properly fire the spark plugs is drained off.

Abstract: A can opening device with a built-in pouring spout that can be affixed to a can of engine oil for use in transferring oil from the can and is equipped with a punch that can be manually operated to open an air vent in the wall of the can. The device has a cutter of conventional type for cutting a pour hole in the top of the can, a conventional guide of the sort that rides against the side of the can to guide the cutter in its cutting operation, and a pouring spout shaped to serve as a handle for use in forcing the cutter through the can top. The punch is pivotally mounted on a metallic arm that is secured to the pouring spout, which arm is bent to extend diametrically across the top of a can to which the device is attached, from the pour hole formed by the cutter, then down the opposite side of the can to a point near its bottom end.

Abstract: A device for holding a pot on a gas range burner in a moving recreational vehicle. The device is attachable to a burner grate of the type having radial bars with sloping lower edges, and it has a deck with lateral edges that interfit with a neighboring pair of the radial bars so as to support the deck on the bars and permit it to span the space between them. A pair of locking levers are pivotally supported at a common point under the deck. From their common pivot point, the locking levers extend forwardly and terminate in outturned, downwardly offset feet designed to swing outwardly into frictional contact with the lower edges of the neighboring radial bars from points intermediate the bars. To the rear, the locking levers are formed into a pair of handles. Mounted above the deck on a pair of pivoted brackets are two clamping members with forward portions formed into curved arms for embracing the pot, and rear portions serving as handles.

Abstract: The carrier has a stiff wire bent to form belt-receiving loops and a frame for supporting a wire mesh fabric bait container having an opening therein. A flexible cloth fabric, such as the upper 4 to 6 inches of a man's heavy nylon stocking, covers the opening and has an access opening therein bordered by a pair of opposed lip portions. Tension springs secured to respective lip portions hold the lip portions together to normally close the access opening and thus prevent escape of the bait, while permitting ready access thereto.

Abstract: A method of stringing tennis racquets, and the racquets resulting therefrom, in which the string is secured to the racquet frame in the form of two isolated sections, namely, a main string section and a cross string section. Each of these two sections is formed from a single length of string and is tied off onto itself so that either section can be replaced without disturbing the other one. Because each of the two string sections is tied off onto itself, the racquet can be easily repaired by the mere replacement of either section found to be defective.

Abstract: A variable speed and direction power transmission attachment for driving the cutting tool carriage of a lathe or the like, the attachment having sets of intermeshing male and female cog gears. Certain of such sets each comprises a face gear having a plurality of concentric rows of tooth socket elements formed therein. A male cog gear is selectively settable to mesh with any of such rows to change the gear ratio. By changing the combined setting of different sets of gears, a wide variation in overall gear ratio may be obtained to provide many different feeding speeds of the carriage, suitable for general cutting and for screw thread cutting. A reversing mechanism, also constructed of intermeshing cog gears, enables the direction of drive to be reversed or the drive to be disconnected to permit manual drive of the carriage.

Abstract: A unit for dispensing water from a bottle. The parts of the unit include an air pump for pressurizing the bottle, a microswitch having a control button connected in circuit with the pump, a small pressure chamber with a distensible diaphragm for a top, a branched air line connecting the pump with the bottle and the pressure chamber, and a cabinet with rollers that can be rolled to a position of use around the upright bottle. Additionally, the unit includes a water line positioned to extend upwardly away from the bottle. A rubber cap encloses the bottle opening and the water line and a branch of the air line are in communication with the interior of the bottle by means of metal tubes passing through the cap. Fastened to the lower end of the metal tube for the water line is a section of flexible tubing long enough to reach to the bottom of the bottle. The microswitch is normally closed and the pressure chamber is positioned with its diaphragm close to the control button of the switch.

Abstract: A sheet metal dent removing tool for attachment to an impacting device, the tool tapering to a metal piercing tip and having a narrow side with opposite convex surfaces converging at their edges to form metal shearing ridges. The ridges, forming the outline of the broad side of the tool, are joined to a neck portion by rearwardly converging shoulders so that when the tool has penetrated the metal and is rotated 90.degree. about its axis, the shoulders lock the tool to the metal whereby the impacting device can be used to pull the dented area back to its initial shape.

Abstract: A control valve for alternately applying fluid pressure to two drive members of a reciprocating work device such as a pump. A valve piston is slideable in a closed cylinder to which pressurized fluid is transmitted. The valve piston, controls the fluid depending on the position of the piston in its cylinder, to pressurize one chamber and vent the other so as to move the work device in one direction or the other. In turn, the work device controls the fluid to position the valve piston.

Abstract: A hold-down device for shirts, blouses, etc., comprising an elastic hipband to be worn around the hips, elastic front and rear flaps secured to the hipband and converging downwardly to fit the crotch of the wearer. Upstanding tabs are spaced around the hipband with means for securing the lower portion of a shirt to the tabs.

Abstract: A measuring dispenser for ice cream embodying a handle carrying an open ended cylinder to be pressed into a mass of ice cream to fill the cylinder. To eject the accumulated scoop of ice cream, the handle and an adjacent lever are squeezed, causing a piston in the cylinder to both rotate and to move axially against the scoop of ice cream. Rotation of the piston, along with a scraper element movable therewith, facilitates breaking of the body of frozen ice cream from the wall of the cylinder and the scraper element scrapes off any ice cream adhering to the wall.

Abstract: A device for indicating when the air within a tire is above or below an optimum pressure range, comprising a housing having a bore therein in which a piston is movable. The piston is spring biased toward one end of the bore and is normally held in a medial sealing position by air pressure from within the tire. In such sealing position, a sealing ring on the piston engages a sealing section of the bore to prevent movement of air along the bore; when the air pressure exceeds or falls below the optimum range, the sealing ring moves over a relieved portion of the bore and allows air to move along the latter to actuate a whistle carried by the piston. An electronic device senses the whistle and signals the operator.
