Abstract: A mounting device for fire hose nozzles of the pistol-grip-type is mountable upon a fire truck or similar vehicle. Centrally disposed in the device is a holster of soft, compressible rubber or similar material, having a tubular form and inclined or canted to accommodate the pistol-grip-type handle of a fire hose nozzle. The holster is protectively enclosed by front and back plates, which can be drawn toward each other so as to reduce the width of the holster, to permit it to accommodate pistol-grips on fire engine hose nozzles of various makes and sizes. A supporting bracket is attachable to one of the retaining plates, and is adapted to be attached to an adjacent surface of the vehicle, in any of various positions, including a position in which the bracket is spaced away from the associated back plate by a stand-off sleeve or spacer.

Abstract: A boat light includes a shield recessed within the hull of a vessel. A conventional sealed beam head-lamp unit seats in an exteriorly spherically shaped lamp unit retaining member formed of a resiliently flexible soft material such as rubber. The retaining member and shield have mating spherically shaped surfaces so that the retaining member can be angularly adjusted, within a pre-determined, limited range, to any of various selected positions within the shield, thus to correspondingly adjust and hence correctly aim, the head-lamp unit. The retaining member is quickly and firmly secured, in each position to which it is adjusted, through the provision of a soft rubber mounting ring, which fits over the inner end of the shield, and is spherically shaped interiorly thereof, to form a ball-and-socket mounting cooperating with the shield and the retaining member.

Abstract: An egg transfer apparatus as disclosed which is adapted to receive eggs from a position thereabove and transport the eggs gently to a location therebelow which includes a carriage plate which is generally vertically movable with respect to a housing. A slide retaining device fixedly secured to the carriage plate defines a slide channel which is adapted to receive therein a slide member which is approximately horizontally movable with respect to the vertically movable carriage plate. A cam arm is rotatably mounted in the housing and a cam roller is secured thereto. A cam follower is fixedly secured with respect to the slide member in a position adjacent the cam roller. Rotation of the cam arm causes engagement of the cam roller and cam follower causing movement of the slide member within the slide channel. With this configuration the vertical movement of the carriage with respect to the housing will cause cyclical horizontal movement of the slide member.

Abstract: A suction type inlet head, adapted for coupling to a fire hose or the like, is lowered into a tank, such as a portable tank known as a "dump-and-go" tank used in fighting fires in rural areas. The suction or inlet head is heavy enough to gravitate to and remain in stable position upon the bottom of the tank, and to this end has a flat weighted base plate which lies directly upon the bottom of the tank. The base plate supports, in a position slightly elevated above the tank bottom, an inlet nozzle retaining plate, having a wide transverse slot for receiving a transversely extending suction cylinder eccentrically, pivotally mounted upon the base. The suction cylinder merges into a hollow connecting portion on which there is provided a hose coupling for connecting the fire hose in communication with the cylinder.

Access to the interior of the oil chamber defined within the handlebars is provided by removable stoppers in the outer ends of each of the arms of the handlebar.

Abstract: An adjustable dumbbell apparatus is disclosed which is particularly adapted to maintain the arms of the exerciser in a straight orientation when used with weighted members which includes a circumferential member defining a hole therethrough through which the arm of the exerciser is adapted to extend. A first and second strut are fixedly secured to the circumferential member to be parallel with respect to the hole therein and extend upwardly therefrom. A grip extends between the upper ends of the struts such that the user can grasp this grip when his arm is extending through the hole in the circumferential member. A weighted support bar is adapted to extend outwardly from the circumferential member and is fixedly secured thereto. The weighted support member extends outwardly perpendicular approximately with respect to the axis of the hole in such a fashion as to use the weights when placed on the weight support member to urge the arm of the exerciser into the straight orientation.

Abstract: A carrier clamp for fire ladders of the folding type, is adapted to be mounted upon a fire truck or the like. A pair of the clamps, when so mounted, accommodate a folding ladder of the type in which the side rails are collapsed into longitudinally contacting engagement. The clamp includes a body having a ladder-receiving recess which may open either upwardly or laterally, depending upon which of two permitted mounting arrangements is selected. The ladder-receiving recess is normally closed by a spring-biased handle, which can be swiftly grasped and pivoted to an out-of-the-way position, to permit swift removal and setting up of the ladder under emergency conditions.The clamp device incorporates removable spacers, to adjust the sides of the ladder-receiving recess to folded ladders of differing widths. In each case, the spacer block includes a cam surface adapted to bear against the ladder when the ladder is forced against the spacer block by the spring biased handle, to hold the ladder securely.

Abstract: An apparatus is disclosed for ordering randomly positioned eggs travelling upon a conveyor into rows. The positioning device includes a plurality of vertically disposed spring abutment members, disposed above the conveyor to contact the eggs as they pass by. The spring abutment members are pivotally mounted for oscillating rotation about an axis perpendicular to the direction of conveyance. The positioning device further includes moving vertical walls, comprising endless belts driven about vertically disposed rollers, whose movement will stop responsive to lateral pressure on the walls caused by egg jams.

Abstract: Disclosed is equipment whereby one may sharpen his or her skills in tennis, while practicing alone. The equipment is of the backboard type, incorporating an upright, panel-like structure located at one end of a surface which preferably is lined to simulate half of a tennis court of standard dimensions. The backboard is provided with a reflective surface, extending over the full width and height thereof, whereby the player sees his reflected image, with the image appearing at the opposite side of and being seen through the interstices of a net simulation incorporated in the reflectively surfaced area. A remarkably close simulation of actual playing conditions, providing a visual impression closely duplicating that which a player would experience when facing an opponent in a match, is thereby produced.

Abstract: A sensing device detects "flashing" in a refrigerant liquid line, upstream from the expansion valves of the evaporators of a refrigeration system. In response, a valve opens in a line extending between the compressor discharge line and a receiver, to bypass discharge vapor into the receiver, thus raising the head pressure to an extent sufficient to satisfy the requirement for a steady liquid refrigerant flow at the expansion valve. The head pressure is raised only to the minimal extent necessary to satisfy this requirement. Disclosed is a sensor of the type incorporating a sight glass in the path of a beam extending between photoelectric cells, though other sensing devices of an equivalent nature can be used. The invention can comprise a single sensing device in the liquid line extending to one or more evaporators connected in parallel.

Abstract: A game board includes an electrical circuit grid underlying a playing surface having a plurality of paths for game pieces each capable of being electrically activated by being placed in a circuit with grid elements disposed in the path along which the game piece is moved. An electrically actuated piece produces a visual and/or audible indication to a player that the game piece is in electrical contact with a "live" portion of the circuit grid. Whether a particular portion of the grid is or is not "live" is determined by the location of a circuit selector switch which closes or opens electrically distinct areas of the grid when operated by a player in accordance with instructions received from a spinner whose operation is governed entirely by the laws of chance. Advancement of the playing pieces along their paths is effected by players according to the instructions received from the spinner, after the circuit selector has been adjusted to a new position.

Abstract: A commercial refrigerated display case, of the type in which an air curtain is directed across an upwardly opening product display space, utilizes ambient air for defrost purposes. A discharge sill extending along the back of the case, above the discharge grille through which air is directed to form the air curtain, is hollowly formed to provide a defrost air chamber. Within the chamber defrost air fans are mounted and are normally off during the refrigeration cycle of the display case. During defrost, the air circulating fan continues in operation although the evaporator coil is no longer in a refrigeration mode. At the same time the defrost fan goes into operation, and draws off part of the air circulated through the discharge grille by the main fan, and exhausts it to ambient through the discharge sill. A weak air curtain is still maintained across the access opening of the display case.

Abstract: An AC switch mechanism utilizes a ball contact to which generally linear motion is imparted by a rockable actuator having a spring providing downward contact force and a spring acting ball pusher leg to provide a snap action. In a single pole configuration disclosed as a typical and basic embodiment of the switch, the ball contact in one extreme position engages and extends as a conductive bridging element between bared conductor wires of an electric cable. The cable thus dispenses with the need for assembling separately made switch terminals with the other components of the mechanism. When moved from the "on" position to its other extreme, "off" position, the ball moves onto sloping ramps having a slight, gradual inclination relative to the lengths of the conductor wires. The construction offers a slow break to provide a minimum arc length before the zero point of the AC cycle, a characteristic of great importance in the design and operation of AC switches.
