Abstract: An earth working apparatus is disclosed including means for removably coupling a compacting roller into operative engagement with a hydraulically manipulated boom while simultaneously maintaining the excavating bucket of the apparatus in its operative association with the boom. The coupling means includes a specially designed link which connects the hydraulic means of the boom to the bucket and which is adapted to receive and engage the compacting roller upon upward movement of the boom.

Abstract: An improved radiator cooling fan has a substantially planar mounting hub and individually twisted blades extending radially therefrom. Each blade includes reinforcing edges along a portion thereof to enhance durability and lengthen useful service life.

Abstract: An automatic dispensing container for containing and dispensing granular material is disclosed which may be constructed from a single piece of sheet material to form a container having an internal ramp partition. The ramp serves to direct the material by force of gravity toward and through a dispensing orifice having a configuration which impedes the free flow of material. The rate at which the material is dispensed is controlled by a structure integral with the ramp which, when moved, serves to assist the flow of material through the orifice.

Abstract: An improved automotive shock absorber assembly comprises a housing containing a fluid, a shaft extending axially into the housing, a piston head connected to the shaft within the housing, a volute spring cooperating with the shaft and piston head and adapted to compress in the fluid when the shaft is subjected to axial loads, means for sealing the housing to prevent the leakage of liquid therefrom, and means for maintaining the shaft in axial alignment within the housing when the shaft is subjected to off-axis loads.

Abstract: A vertical record card can be held at selected levels in sound recording or reproduction association with a recorder-player adapted for cassette contained record tape.
