  • Patent number: 4761111
    Abstract: A truck for towing disabled vehicles is provided with a cab controlled or a remote controlled vehicle lifting assembly including pairs of claws which may be positioned to engage a pair of the wheels of a vehicle and then be actuated to cradle the wheels and enable the vehicle to be lifted and towed, the vehicle being carried on its own suspension system during towing. The assembly includes a crane mounted and arranged so that the load thereon is carried forward of the rear axle of the tow truck--this increases the tow capacity of the truck and provides stable operation of the crane. The positioning of the claws is effected by hydraulic actuators of the like which may be operated by remote control.

  • Patent number: 4745340
    Abstract: A power supply system for portable floodlighting equipment employing high-intensity electric discharge lamps comprises an alternating current generator having three or more independent armature windings, one for producing independently current at a voltage sufficiently high for starting a discharge lamp in series with a capacitor. The windings are out of phase with one another and interference with the operation of the lamps energized by the separate and independent windings and electric apparatus energized by the standard voltage generator is effectively eliminated. The use of the generator winding for starting and energizing the lamps eliminates the usual starting ballast and decreases the weight and cost of the portable floodlighting unit.

  • Patent number: 4739944
    Abstract: A spinning reel for fishing which is arranged to retrieve the line either by a hand crank or by an electric motor. Either of the alternative drives may be actuated without effect on the other. The entire mechanism including the electric motor and batteries is enclosed in a single casing. Either of the controls for retrieving the line may be used without requiring operation of a preselecting mechanism. The motor drive control of the illustrated embodiment comprises an axially slidable worm wheel driven by the motor and biased to its driving position and which is moved against the bias and out of its driving position by operation of the hand crank.

  • Patent number: 4696258
    Abstract: A substance for facilitating the detection of estrus applied to the tailhead and rump of a cow as a patch comprises a mass of microencapsulated dye mixed in a suitable paint. The paint dries as a durable layer the color of which will change when substantial pressure is applied for a predetermined time. Should the cow be mounted by another animal for say five seconds or more a large portion of the microcapsules will break and release the dye which colors the patch. The cows with colored patches can then be found by periodic inspection and removed from the herd for insemination.

  • Patent number: 4656744
    Abstract: A device for marking wall panels or the like with irregular lines, which conform to irregular surfaces such as stone or brick walls, comprises a bar and a slide adjustable thereon to selected distances from the wall to be traced. The slide including a tube mounted on the slide at right angles thereto for receiving a pencil or stylus, the tube has a central hole adjacent the slide and a conical sharpened pencil will fit both holes and lock the pencil in position for tracing a line. A swingable handle is pivoted at the other end of the bar from the tracing point, and swings in a plane spaced from that of the bar sufficiently to allow the operator to grip the handle without interference with the bar. The user grips the handle and the pencil and holder, and, while keeping the bar horizontal holds the point against the irregular wall and moves it along the wall to trace the irregular line on a wall panel or the like. The wall panel may then be cut to the line which will fit the wall closely.

  • Patent number: 4631989
    Abstract: A ratchet handle for use with socket wrenches includes a socket engaging projection on which socket wrenches having a first size of coupling socket can be mounted for turning by the handle. The handle includes a bar slidable within the projection and movable from a position within the projection to a second position with its end extending axially beyond the projection. Socket wrenches having a second and smaller size of coupling socket are mounted on the handle by engagement with the extended end of the bar. The bar is retained in either of two positions by spring pressed balls or detents which engage two shallow recesses in the projection in one position and in the extended position of the bar one of the detents lies outside the projection in position to engage a socket coupling mounted thereon. In another embodiment the bar is biased by a compression spring to its position within the projection and a cam on the bar urges a detent outwardly to retain the larger socket on the projection.

  • Patent number: 4601315
    Abstract: A device for holding a flexible trash bag is arranged for mounting on a garden cart of the type having parallel handle arms extending rearwardly from the top of the cart body. The device comprises a flat sheet having upstanding side walls and arranged to extend across the handle arms from adjacent the top of the cart. Bag holding structure is provided under the rear edge of the sheet and when the device is installed on a cart, grass cuttings or other refuse may be swept out of the cart and over the sheet into the bag; the bag may be kept open by holding it by hand against a cross member between the ends of the arms.

  • Patent number: 4596572
    Abstract: A device for transferring a liquid from a bottle at substantially atmospheric pressure to a bottle at a low pressure comprises a hollow needle of steel or the like mounted in a grip or handle member having a configuration to facilitate the pushing of the needle through a bottle stopper at either end of the device. The needle is sharply pointed at both ends and the handle consists of a strip of steel or other suitable metal bent at its ends to provide stops having holes to accommodate the needle which extends beyond the stop at each end. The strip is bent or bowed toward the center portion of the needle and is soldered or otherwise secured to the needle. The sloping portions of the strip provide thumb rests for pushing the needle in either direction.

  • Patent number: 4594824
    Abstract: A telescoping mast assembly for floodlighting equipment or other apparatus is arranged to be raised by admitting pressurized fluid to the interior of the assembly and lowered by releasing the fluid. The assembly is constructed of light metal, such as aluminum alloy, and includes a plurality of telescoping hollow members, or tubes, each inner member having a pair of substantially spaced wear rings near its lower end for maintaining the spaced positions of the members and a fitting at its outer end carrying an internally mounted wear ring for maintaining the spacing at the outer end. The telescoping members do not engage one another but are spaced by the wear rings. The fitting is readily detachable and facilitates the use of straight lengths of standard aluminum tube stock for the mast sections. The fittings include keys slidably engaging longitudinal slots in the members for preventing rotation of the members with respect to one another. Seals are provided for preventing leakage of fluid between the members.

  • Patent number: 4590810
    Abstract: A device for collecting samples of water from wells and the like comprises an elongated container having valves at both ends which valves are arranged to open when the container is lowered in a body of water and to close when the container is stopped and to remain closed when the container is being raised to the surface. The device traps a sample of the water at the position at which the device is stopped, and the container is held closed during the entire return to the surface.

  • Patent number: 4539985
    Abstract: An aspirator and resuscitator for newborn animals comprising a cylindrical accordion bellows and adaptors for removing fluids from the nasal and oral passages and for delivering air to and removing air from the breathing passages. The bellows and an adaptor are connected to a central handle which is also the fluid conductor between the bellows and the adaptor. The position and arrangement of the handle provide an effective grip for the whole hand and facilitate the holding and operating of the device effectively and quickly and with safety for the animal. An arrangement is provided for assuring effective and uniform stacking or compressing of the bellows pleats and minimizing the likelihood of damage to the bellows during use.
