Abstract: A retainer for immobilizing a bucket containing a liquid material, such as paint or other relatively viscous liquids, during mixing the material or to prevent accidental tipping of the bucket, is formed with a ring-like socket within which the bucket is positioned. Laterally-extending wings are formed on the socket. The user stands upon the wings to hold the socket against the ground-supporting surface upon which the socket is supported so as to prevent rotational or other movement of the socket and, consequently, movement of the bucket. The socket is formed of a generally cylindrically-shaped, vertically-axised wall which is tapered inwardly from its upper edge to its lower edge at a sufficient slope to radially inwardly frictionally grip and temporarily lock the bucket within the socket.

Abstract: A foldable umbrella-like cover for covering the open top of a golf club bag and golf clubs extending out of the bag, includes a vertically elongated tube that is centrally positioned within the bag, along with the golf clubs, and is releasably clamped to the wall of the bag. A vertically slidable, elongated rod extends into the tube. A ring-like collar is attached to the lower end of the rod, and the upper end of the rod is provided with a manual grip for sliding the rod into and out of the tube. A number of umbrella ribs are connected, at their inner ends, to the collar so that such inner ends may be moved, with the collar, for retracting the ribs into the tube, for closing the umbrella, or alternatively, extending the ribs outwardly of the tube for opening the umbrella. A flexible cloth-like umbrella cover is secured to the ribs and moves into and out of the tube with the ribs.

Each plastic T-bar monorail track section comprises an upstanding stem having a laterally extending pendant lobe on each side thereof and a pair of laterally outwardly directed flanges at the distal end of said stem for both horizontal and inclined travel of the conveyor trolleys.

Abstract: A two-piece plastic clevis device for a monorail conveyor trolley system, the device having an upper trolley connected member and a manually engageable and disengageable lower clevis member which is connected to and supports a parts carrying hanger. The upper clevis member has a flanged member on each side of a medial plate or stem, the lower member having a pair of spaced apart hub-supported arcuate bodies that engage the flanged members on each side of the medial plate and suspend the hanger at and from the surfaces of engagement.

Abstract: A plastic conveyor trolley structure having plastic bearings and made of a super tough plastic material, comprises a pair of complementary arms each supporting a wheel for rotation on roller bearings held in a fixed inner race forming an integral part of a stub axle on which the trolley wheel is rotatable. The trolley is readily movable on the flanges of an I-beam monorail. A pendant member secured to and between the lower ends of the trolley arms is engaged by the conveyor drive chain to move the trolley along on the monorail. Metal screws are used to hold the depending member to the arms and to secure the stub axle for the trolley wheel to its supporting arm.

Abstract: An engine cradle fabricated of integrally molded unitary plastic components including four corner posts, a front transverse bar connected to a first pair of corner posts and a rear yoke plate member connected to a second pair of corner posts, a pair of lateral force distributing x-shaped cross members connected to both said pairs of corner posts, engine rest surfaces and movement restraining means at the upper distal ends of the corner posts in engagement with an engine carried by the cradle, and fastening means conjoining the plastic components together into an engine supporting and protecting device.

Abstract: A material handling rack to translate articles having in part a V-shaped cross-section, at which the article is at least partially supported, and spaced apart relatively opposing generally upwardly-facing plastic article-support members removably secured to transverse rails affixed to the rack frame. The transverse rails are arranged in parrallel from one longitudinal end to the other and define open spaces therebetween for admission of said articles to be supported by the said plastic members which are secured to and extend laterally from the transverse rails into the region of the open spaces therebetween. Manually operable plastic detent hold-down arms are movably attached to the plastic support members to alternately engage with or disengage from laterally extending surfaces of the articles whereby to secure the latter in or release them for removal from the rack frame.

Abstract: A supporting rack comprises a plurality of cradle sets arranged in a series upon a lift platform, to translate a plurality of substantially identical load units or subassemblies, one to each cradle set, from one station or location to another. The cradle set comprises a pair of parallel, opposed, spaced apart nest members having elements projecting laterally therefrom in opposing relationship to support a load unit or subassembly therebetween, and a pair of lateral separator and tieing members removably secured to the ends of the nest members whereby to maintain the latter in upright, spaced apart relationship for facile reception of the said load unit or subassembly by and discharge from the nest members. The cradle sets can be arranged in parallel, adjacent, side-by-side series, in which case one of the lateral separator and tieing members is designed to separate and connect the nest members of parallel, adjacent, side-by-side cradle sets.

Abstract: A pallet to support a component device for processing and testing, the device being removably secured to and upon the pallet for translation from a mounting station through one or more processing or assembly stations and optionally to a testing station, for elevation and lowering at the testing station, and for translation to a repair or discharge station, on conveyor devices moving the pallet by friction drives or other means. The pallet is made substantially entirely of a very tough nylon resin or equivalent plastic material. In one of its preferred forms the pallet comprises a grid body, an upper support plate member, a lower driven plate member and bumper bars on the side edges of the pallet. In a second preferred form the pallet comprises a grid body and an upper support plate member; and in a third form the pallet comprises a unitary molded grid body closed on its bottom side except for drain and bolt openings therethrough. The second preferred form of pallet can also be molded as a unitary device.

Abstract: A protective face mask to shield an x-ray technician or machine operator primarily from random secondary or scatter x-rays deflected toward his face, head and neck by the table, walls, equipment and other reflecting elements in an x-ray room, during the period of exposure while adjacent the object or person being exposed to the x-ray beam.The face mask is formed of a lens portion supported in a plastic frame, upon the lower portion of which is removably attached a bib shield that in turn is removably attachable to an apron. The frame of the face mask, bib shield and apron are preferably lined with lead sheets to protect the neck, face, chest and body of the technician from the random secondary or scatter x-ray beams. The face mask and bib shield can be formed of a molded plastic material as a unitary device, the lens portion being attached to the frame therefor.

Abstract: A plastic material handling rack adapted to receive and translate small or relatively large parts or units, capable of being stacked vertically one rack upon another, and to be loaded by conventional fork lift trucks into transportation vehicles. The plastic material handling rack is assembled with corner posts, side rails and end rails that form the unit into a rectilinear framework. A floor plate is removably attachable to the framing. Transverse rails are attached to the side or end rails for support of larger machine units or devices, and solid or perforated side walls are attachable to the corner posts and upon the side rails and end rails, converting the open framework of the rack into a tub rack.

Abstract: A conveyor trolley structure made of a plastic super tough nylon material comprises a pair of arms each supporting a wheel for rotation and bearing upon the flanges of an I-beam monorail. A pendant member is secured to and between the lower ends of the arms. Metal screws are used to hold the depending member to the arms and to secure stub axles for the trolley wheels to their arms.
