Several embodiments of frames are included, one being formed by folding a sheet of material along fold lines, and another being of rigid construction.

Abstract: A manually operable tool to knock out identification slugs from the heads of keys such as ignition and door keys for automotive vehicles while the keys are mounted upon a key ring passing through holes in said slugs, the tool comprising a pair of jaws on handles pivotally connected adjacent the jaws, one jaw having a seat to position the end portion of the head of a key which is beyond the slug and the other jaw having a pair of spaced lugs positioned to straddle the key ring and engage the opposite portions of the slug which are on opposite sides of the hole in said slug to punch said slug from said head of the key when said jaws are moved toward each other.

Abstract: A combine harvester having crop cutting and elevating means at the forward end of the combine to deliver crop material to be threshed to a threshing compartment in which axial rotor and concave means thresh and axially move the crop material to straw walker means immediately rearward of said threshing compartment to separate straw and chaff from threshed crop material and discharge the straw and chaff from the rear end of the harvester.

Abstract: A bur grinding machine especially adapted to grind dental burs and including a turntable supporting a plurality of similar workheads having collets to support bur blanks; a plurality of grinding units mounted on a stationary base in circumferentially spaced locations around the periphery of said table and respectively operable to perform different grinding operations in sequence upon the heads of bur blanks; means to index, rotate, and advance the collets of the workheads automatically at each grinding unit to form a plurality of teeth upon the bur blanks; means to index said table to advance the burs in the workheads to the next grinding unit; means to feed and accurately position bur blanks within the collets of the workheads; and means to control the cycle of the machine throughout.

Abstract: A pulverized coal burner for a furnace adapted to be used in conjunction with a pulverizer which reduces coal to approximately 40 microns size in the presence of inert steam which conveys it under pressure to said burner tangentially to spiral the same within a fuel tube around a coaxial central tube axially adjustable within the fuel tube to adjust the relation between flared distribution and mixing members respectively on the discharge ends of said tubes. Combustion air is fed coaxially around the discharge end of the fuel tube for thorough mixture with the coal which is conveyed with a minimum amount of steam through said tube so as not to deter combustion in the combustion zone which is immediately adjacent the discharge end of the fuel and central tubes.

Abstract: A solar collector utilizing elongated channel-shaped reflector members which comprise modified parabolas in cross-section to reflect sun rays onto straight sections of a tubular conductor of heat-transfer fluid located substantially along the focal lines of said reflector members and being oval in cross-section to intercept the rays of the sun as the position of the sun rises above and falls below the central axes of said reflector members, a series of said reflector members and conductors being horizontal in use for gravity drain and flow and the ends of the straight sections being connected to provide a sinous tube system. An insulating frame supports said reflector members and tube systems and a transparent cover extends across the outer face in use.

Abstract: A fuel filling funnel and oil charging means in which a cylindrical receptacle is hingedly connected to the rim of a conical funnel. The receptacle has a closed end provided with an adjustable discharge opening and the opposite end being open to receive a container or cartridge of lubricating oil, said end being adapted to be pivoted upwardly to discharge the oil into the funnel for mixture with liquid fuel such as gasoline which is simultaneously discharged into the funnel. Latch mechanism releasably secures the receptacle in the discharge position for the oil, the purpose being to relieve operator's hands for use to hold the funnel and a fuel nozzle while filling the tank of a two-cycle gasoline engine or the like without manually holding the oil receptacle.

The filter element is supported by a frame and includes means to raise and lower the frame respectively to support the filter element in upper, operative position and lower, removable position, insertion and removal of the same occurring through an opening adjacent one side edge of the roof of the cab and normally closed by a door, the entire removal occurring exteriorly of the interior of the cab.

Abstract: A hand-operated device comprising a handle having a rotatable shaft supported by the handle and one end projecting beyond one end of the handle and having means to support removably thereon a conventional hair curler. A spool is affixed to the shaft and has a flexible cord-like member coiled therearound, whereby when the outer end of said member is pulled, the shaft and curler thereon is rotated for purposes of winding hair upon the curler. For purposes of restoring the cord-like member to coiled condition, a circular friction member is mounted upon the shaft and is adapted to be rolled along a suitable surface in one direction to coil the cord-like member upon the spool to arrange the same in starting position.
