Abstract: A ball socket member molded of resilient resin material is open at one end to receive and retain a ball in a part spherical cavity within the body communicating with a chamber containing a lubricant. The socket member carries a skirt at its open end which is adapted to form a seal with a member which carries the ball to prevent leakage and/or contamination of lubrication contained within the body cavity. Relief grooves are formed in the socket member which distribute lubricant on the ball and vent excess lubrication from the cavity as the ball is pressed into the cavity. The socket member has a polygonal external surface having a circumferential groove formed therein which receives the portion of the linkage member surrounding a complementary polygonal opening therein, so as to anchor the socket member against rotation relative to the linkage member.

Abstract: A manual utility cart including a frame having spaced cargo retaining portions and a lower portion. An axle journaled in the lower portion of said frame journals a first set of wheels. A second set of wheels is journaled on an axle spaced from and supported by said first axle and is shiftable about the first axle between a retracted position and a frame supporting position to raise the first set of wheels from a surface. A cover overlies both sets of wheels to support a cargo within the frame.

Abstract: A cart including a detachable carrier for moving firewood from a stockpile to a fireplace within a living quarter. The cart includes large wheels for movement over rough terrain while the cart is loaded and a set of smaller wheels for movement of the cart within buildings. The cart also includes a stair climbing apparatus to enable pulling a loaded cart up a flight of stairs. In one embodiment the smaller wheels are shiftable between a raised and a lowered position for selected usage upon operation of a linkage. In a second embodiment the smaller wheels are journaled on the detachable carrier.

Abstract: A protective member for use in securing metal coils to a transport vehicle or other support. The member is formed of hard, wear-resistant material having a coil contacting surface and an opposed surface. The opposed surface is grooved to receive a cable, chain or other securement member which spans the coil and whose ends are secured to the vehicle or other support. A plurality of magnetic strips are secured to the coil engaging surface of the block for positioning the block on a metal coil. Releasable chain or cable retaining means are carried by the member transversely of said groove.

Abstract: An expansion bulb for plugging a conduit or passage which includes an expandable sleeve encircling a body and secured to the body by caps securing opposite ends of the sleeve to the body with each end of the sleeves extending into recesses in the body. Pressurized air or fluid is supplied through a passage in the body to cause radial expansion of the sleeve relative to the body.

Abstract: This security device is designed for padlocks, so as to prevent their shackle members from being cut by a bolt cutter or a hacksaw. Primarily, it consists of a main body, which nestles the padlock, and which leaves no room for the operation of a bolt cutter or hacksaw to remove it from the assembly. The assembly further includes a strap for engaging with whatever is to be locked, and it includes a clevis pin for retaining the assembly together, in combination with the lock.

Abstract: A valved discharge member for use with the water supply system for use with cages of fowl and small animals, wherein a valve element in the member engages two spaced valve seats and is unseated by movement laterally and upwardly of a pin extending through a discharge opening and projecting below the housing.

Abstract: A broadcasting apparatus for pulverant or granular material including a frame supported by wheels, an axle extending between the wheels and connected in driving relationship with at least one of the wheels, a material hopper mounted on the frame and having an opening in its bottom wall, a valve adjustable across the hopper opening to control the flow of material therefrom, a guide for the valve to retain the valve in selected position adjacent the hopper opening, a dial having a cam surface, a member connected to the valve and bearing on the dial cam surface, a mount for the dial connected to the bottom wall of the hopper and guiding the connecting member, a broadcasting plate disposed beneath the valve and connected to the axle to rotate upon movement of the wheels, and an agitator within the hopper connected to rotate with the shaft and broadcasting plate.

Abstract: A roof cavity venting system which draws in outside air, mixes it with inside air in the roof cavity to heat the cold outside air and dehumidify the inside air, and expels the mixture into the home living quarters. The system includes exterior and interior ventilation units, a power-driven fan unit mounted in the ceiling between the living quarters and the roof cavity, and a heating element for heating the air which is drawn through the fan unit.

Abstract: A platform for attachment to an aerial boom, said platform being constructed of lightweight dielectric material and mounting collapsible guard rails. The platform includes braces which stabilize and position it on the aerial boom.

Abstract: A venetian blind and frame unit for vehicles, such as vans, wherein the frame conforms to the shape or curvature of the vehicle wall. The blind is secured within the frame at upper and lower headers thereof and is tensioned so as to substantially conform to the angle of upward and inward inclination of the vehicle side wall. One of the headers includes a projecting pintle which is retractable to permit placement of the header pintles within openings in the frame. The lower header is releasably secured to the lower end of the frame to allow raising of the blind within the frame.

Abstract: A hydraulic control system which is of an open center parallel circuit arrangement for aerial boom devices with two return lines, said system having control valves for upper and lower boom arms, wherein the lower boom control valve overrides the upper boom control valve. The system includes a valve connected to a pump actuating engine and responsive to hydraulic pressure to increase the speed of the fluid pump when the flow or pressure in one return line is reduced due to diversion of fluid within the system into the second return line. The system also includes a normally open relief valve carried by the boom supporting turntable adjacent its pivotal connection to the lower boom and operable to control a winch actuator and to deactivate said winch actuator when the boom is in an unstable position.

Abstract: A display and storage assembly constituting a plurality of interlocking stackable bins with each bin having a top, bottom and opposed sides incorporating fasteners which permit the bins to be interlocked in a juxtaposed side by side relationship.
