The tapered ends of the ribs are attached to a common sheet of material which may be inserted underneath roofing shingles to position the entire assembly over a gutter to provide assistance to propel leaves, pine straw and other debris to the edge of the gutter but at the same time preventing the debris from entering the gutter while allowing the water to drain into the gutter. A continuous front member may be provided with clips for attachment to the edge of the gutter or may be omitted.

Abstract: A watchman's tour recording system includes a portable housing containing a data reader for reading and recording data from tour stations and a printer for printing out recorded station data and entry time in alphanumeric form. The printer is located in a locked compartment and is accessible by supervisory personnel for periodic tour entry monitoring. Station keys carry coded identification as a linear array of apertures filled with alternative pellet materials which are transmissive or non-transmissive to infrared light but are visibly indistinguishable. Strobe holes are positioned in a parallel linear array for synchronizing data reading. During assembly, the pellets are mutually distinguishable by split and continuous rings which serve as energy directors during ultrasonic welding of the pellets into the key, and which are hidden from view in the assembled product.

Abstract: The first of four adjustments for the shock absorber located between the rear wheel and main frame of a motorcycle is an externally accessible filler-valve enabling the rider to adjust gas pressure in one chamber to vary spring rate and respectively a second adjustment for varying the rate of hydraulic fluid from a main chamber through a main piston to a third chamber by means of a second valve to obtain the desired rate of upper wheel travel, a third adjustment which is an adjustable pressure relief third valve to limit differential pressure between fluid in the main chamber and in the third chamber under conditions of severe impact for the rider to select damping characteristics and a fourth adjustment valve varying fluid flow from a fourth chamber to the third chamber for the rider to adjust damping during extension. Optionally, there is an air cooler chamber around the main chamber and in communication with the carburetor.

Abstract: The end of an axle spindle is provided with right hand and left hand threads to receive respective axle nuts. The inner nut thread diameter is larger than the outer nut thread diameter in order to avoid interference. The wheel, bearings and an inner nonrotatable washer on the axle spindle are secured in place by tightening the inner nut to an initial snug (no clearance) condition against the face of the nonrotatable washer. One of eight holes on the outer face of the inner nut receives a projecting pin of a spacing control device which pin projects a predetermined distance. The outer nut is turned until the spacing control device engages one of the eight recesses. Then the flats of both nuts are tightened by a spanner wrench which causes the inner nut to "back off". The method is to create a space between nuts (e.g. by use of a shim spacer) which converts to an appropriate clearance space between the inner nut and nonrotatable washer in the final condition and to maintain that space in the final condition.

Abstract: A machine frame has a foraminous, inclined screen drum mounted for rotation thereon with an opening in one end which receives the peas for engagement by flat paddles attached in spaced relation to a horizontal, internal paddle shaft supported for rotation within the drum. A separating member supported on and rotating with the drum is spaced from the inside of the drum. The peas (kernels) fall through a closed housing to a shaker at the bottom and are collected in a pan. The hulls and trash are directed through the drum past the separating member and out of an opening at one end and into a trash bag. A blower on one end of the machine blows the trash through the housing. A drive means drives the drum and the paddles in opposite directions and also operates an eccentric to reciprocate the shaker.
