Abstract: A hinge unit is provided for doors and casement windows by an arrangement of four like pins each having a shank extending from an enlarged head. A first pin with a threaded bore through the head has the shank threadably secured to the door or window so that the bore therein is horizontal. A second pin with a like threaded bore through the head has its shank threadably secured to the first pin with the bore in the second pin vertically disposed. A third pin with an oversized smooth bore through the head has its shank threadably secured to the wall adjacent the door or window with the bore vertical. The head of the third pin is disposed above the head of the second pin so that the respective bores are in registration. The fourth pin has its shank journalled through the oversized bore of the third pin and threadably engaged in the head of the second pin. In an alternative arrangement, as a matter of choice, the second pin may be secured to the wall and the third pin secured to the first pin.

Abstract: A diamond point type dressing tool is mounted in a control head assembly capable of producing horizontal and vertical movements of the tool either independently or simultaneously to reproduce from a remotely disposed associated template any desired contour of angles and radii on the peripheral edge of a grinding wheel. A tracing rod, snugly but slidably journalled through a fulcrum support, has a tracing end adapted for manual movement over the profile of the template and a control end operatively associated with the control head for reproducing the template profile in the movement of the dressing tool. The fulcrum support is fixed against lateral or vertical movement but has the capability of turning in place as the orientation of the axis of the rod is changed during movement over the profile.

Elongated rods secured at one end to the rake are pivotally connected at the other end to a power driven endless chain for travel therewith towards and away from the screen with such chain and power supply being remotely located at a point free of contact with the waterstream.

Abstract: A hand wrap is provided for athletes with particular usefulness in the sports of boxing and football for the protection of the hands, knuckles and wrists. The wrap comprises an elongated preferably two inch wide strip of flexible woven cotton twill having a first thumb engaging loop at one end from which the wrap is trained across the palm and back across the back of the hand and the knuckles to a second thumb engaging loop. Intermediate the two thumb loops and on the initial portion to traverse the knuckles there are two spaced loops for engaging respectively the index and little fingers. The remainder of the strip is wound about the hand over the knuckles with intermediate turnings about the wrist to terminate about the wrist where the other end of the wrap is provided with a self-fastening means. Padding is preferably provided in the wrap on the initial knuckle engaging portion.

Abstract: A heat generating device includes a sealed metal drum with spaced peripheral fins and houses a cage-like agitator mounted on a rotatable shaft axially disposed therein and extending through one end for connection to a source of power. The agitator includes a plurality of elongated flat bar-like vanes arranged in close concentric relationship to the drum and supported by spaced apertured hubs on the shaft. The periphery of each hub has serrated type notches so that the vanes are tangential to the hubs and in off-set alignment with each other. Relative to the direction of rotation of the agitator, the leading edge of each vane is spaced inwardly from the trailing edge of the adjacent vane a predetermined distance to provide a restricted passageway.

Abstract: A bat board construction of a harvester reel for use in harvesting soybeans includes an elongated shield of tear drop configuration having its widest dimension at the top and its lower and narrowest portion secured to a substantially rectangular bat board and operatively secured at respective ends to a harvester reel for rotation therewith. The wide end of the shield is several times greater than the narrow end and of sufficient breadth so that as the narrow end enters the crop, the relatively wide top serves to maintain separation of the stems and pods of the plant to prevent their inherent tendency when in contact to cling together and to become wrapped around the bat and reel instead of being drawn into the operating mechanism of the harvester.

Abstract: A bow assembly is removably attachable to an open top truck bed for supporting a tarpaulin cover and includes a plurality of relatively light weight and easy to handle components for quick assembly and disassembly by one person. The assembled structure includes a plurality of spaced transverse bow units and headboard connected by longitudinally aligned removable supports with the bow units being telescopically slidable on supports attachable to the sideboards of the truck to permit flexing as cargo is loaded or unloaded. The headboard protects the cover from displacement by headwinds and includes means for deflecting water off the sides of the cargo bed.

Abstract: An insulated ice cooled container is mounted on a wheeled road traveling trailer equipped with tongue, hitch and traveling lights and attachable to a towing motor vehicle. The container is designed to hold a plurality of receptacles for beverages such as beer kegs and the like to be transported to a point of use for on-site dispensing. Dispensing hoses for the contents of the receptacles are trained through ice in an ice chamber and connect to valved spigots mounted on and exteriorly of the container. The trailer carries apparatus for pressurizing the contents of the receptacles and includes a jack leg for maintaining a level position of the container when detached from the towing vehicle. Separate latchable doors are provided for the ice chamber and the carrying area for the receptacles.

Abstract: A multi-vane windmill rotating in a horizontal plane on a vertical shaft includes frame supported fabric type vanes with the frame hingedly attached at one end to support arms to swing closed and catch the wind in one position and to swing open under centrifugal and wind forces in another position when coming into the wind to reduce air resistance. Vanes are releasably attached in part to the frame for support in operating position and otherwise slidably secured thereto so as to release and collapse on the frame under extreme wind pressures when the frame is closed and thus spill the wind. Stops on the support arms provide a limit of movment of the vane frames. A second embodiment of the vanes includes two overlapping sections normally held in overlapped or closed position by yielding means that permit the sections to separate under high winds to provide an air passageway through the vane.

Abstract: A material unloader for forage or the like includes a closed box-type body having interior unloading mechanism for delivering material to an exterior chute and has at least one, and preferably two, latchable closures for providing access to the body interior. The unloading mechanism is designed for connection to a source of power exteriorly of the body and locking apparatus on the closures is arranged for purposes of safety so that the unloading mechanism must be rendered inoperable to effect the opening of any closure and cannot be made operable while any closure is open and affording access to such mechanism. This unloader may be mounted on a wheeled chassis for towing or mounted on a self-propelled vehicle.

Abstract: A flexible cover is provided for an open top truck bed and includes means for rolling by one person from one edge at one side of the bed in a cylindrical roll across the bed transversely of the width thereof to a position of storage at the opposite side of the bed. A length of cord is secured at one end to a generally central point on the roll starting edge of the cover so as to roll up with the cover and leave a trailing length which can be grasped and pulled to effectively unwind the rolled cover back across the truck bed. The cord also serves as a tie-down for the cover when unrolled. Fastening and tensioning means as required are provided for the cover in rolled and unrolled positions.

Abstract: A two way travel three section drawer slide assembly is provided for cabinets, desks, files, service vehicles and the like to permit a drawer to be selectively extended from opposite sides. The assembly includes an outer channel section for attachment to a support body such as a cabinet wall, a central channel section slidably mounted within the outer section and an interior channel section slidably mounted to the central section and fixedly attached to the drawer to be moved. The present invention particularly provides improved movable stops wholly within the confines of the assembly to facilitate and assure the proper movement of the central section to full extension and full retraction whereby no latching or locking devices exteriorly of the slide assembly are required. Latch members on opposite sides of the drawer and support body prevent accidental outward movement of the drawer. This invention is also usable on drawer assemblies having more than three sections.

Abstract: A combination high pressure and vacuum relief valve to relieve excess pressure buildups and overload surges in gas and fluid flow lines, to release and break up any vacuum conditions which might develop in the opening and closing of flow in such lines, to serve as an air bleeder device to exhaust trapped air when the flow system is started up and to provide an air cushion against any slam or hammer action in the operation of the valve. A gravity operated vacuum breaker buoyant closure means is used with a pressure relief vented valve means operably connected to an air cylinder.
