Definitions
- An upright, generally cylindrical discharge chute is rotatably mounted on the upper end of a tubular vertical conduit leading upwardly from the snow-gathering housing of a powered snow-removal unit of the type known as a snow-caster.
- the chute is locked on the conduit by a tubular cord that fits into concentric semicylindrical grooves of the two members, and rotation of the chute relative to the conduit to vary direction-a1 orientation of the discharge opening at the upper end of the chute is controlled by a power-actuated lever which is connected to the chute by means of a cable.
- the present invention relates to apparatus for controlling the movement of one structural member relative to an associated member, and more particularly concerns an improved mechanism for mounting a discharge chute on the housing of a conventional snow-caster and for controlling the adjustable rotation of the chute relative to the housing to vary the directional orientation of a discharge opening at the upper end of the chute.
- the chute control mechanism of the present invention features a double-acting power cylinder that is connected to one end of a lever which is pivoted at an intermediate point on the top wall of the housing of a snow-caster.
- a cable which is connected to the lever adjacent the power cylinder connection, is wrapped around and secured to the chute and has its opposite end connected to the end of the lever that is on the other side of the pivot axis from the power cylinder connection. Accordingly, when pressurized fluid is directed to one end of the power cylinder, the lever is pivoted counter-clockwise to cause a pull on the cable and rotate the chute in a first direction.
- a single power cylinder, a single lever, and a single cable are effective to control the rotary position of the snow-caster chute.
- FIG. 1 is a schematic side elevation of the chute adjusting mechanism of the present invention shown mounted on the housing of a snow-caster which is propelled by a typical garden tractor.
- FIG. 2 is a section taken along line 2-2 of FIG. 1.
- FIG. 3 is a fragmentary enlarged vertical section taken along line 33 of FIG. 2.
- FIG. 4 is a section taken along line 4-4 of FIG. 3.
- the reference numeral 10 indicates generally a portion of a relatively small powered vehicle of the type commonly referred to as a garden tractor. These vehicles are adapted to carry and operate various mechanisms such as lawn-mowers, rotary cultivators, and plows and the like and, in FIG. 1, the vehicle 10 is illustrated in driving and pushing engagement with a snow-caster 12.
- the snow-caster is of the type that has a housing 13, open at its front side, and helical snow-gathering elements 14 in the housing which remove snow from the ground and force it inwardly from the opposite ends of the housing toward a rotary impeller that hurls the snow upwardly through a tubular conduit 16 which communicates with the interior of the housing through an opening 18 (FIG. 3) in the top wall 19'of the housing.
- the upper end of the conduit 16 is cylindrical and is provided with an annular, generally semi-cylindrical, outwardly-facing groove 21 in its outer surface.
- a discharge chute 22 has a cylindrical lower end 22a on the inner surface of which is an annular, inwardly-directed semi-cylindrical groove 23.
- a Teflon tube 30 is disposed in the opening formed by the two oppositely-facing grooves and is effective to act as a key to engage the walls of the composite groove and prevent separation of the chute 22 from the conduit 16 while acting as a bearing to facilitate relative rotation of these members.
- the Teflon tube is positioned in the composite groove after the chute 22 has been brought to the position shown in FIG. 3 over the upper end of the conduit 12.
- a setscrew 32 (FIG. 4) is threaded into a tapped hole 33 in the lower end 22a of chute 22 so that the inner end of the screw projects across the groove.
- the tube 30 is then inserted into a passage 35 in the chute portion 22a which leads to the composite groove.
- the tube 30 is of a length such that, when its leading end abuts the setscrew 33, its trailing end will be far enough inside the passage 35 to permit a pipe plug 36 to be threaded into the passage to lock the tube 30 in the groove.
- a double acting hydraulic power cylinder 50 (FIG. 2) has one end 50a pivotally mounted on a rigid flange 52 that is secured to and projects upwardly from the top wall 19 of the housing.
- a rod 54 connected to the piston of the cylinder 50, is pivoted at 55 to a flat lever 56 which is in turn pivoted at 57 to the top wall 19.
- a metal cable 60 has an end portion 60a that passes through an opening 62 in an upstanding tab 56a of lever 56 and has a collar 64 secured thereto.
- the cable is trained around a pulley 66, which is rotatably mounted on top wall 19, and the bight of the cable is disposed ina spiral groove 68 (FIG. 3) in the outer surface of the chute 22.
- a setscrew 70 locks the cable to the chute.
- the cable is also trained around a second rotatable pulley 72 on top wall 19 and has an end portion passing through an aperture in a flange 56b of the lever 56.
- a coil spring 74 encircles the cable 60 and is disposed between the flange 56b and a washer 75 that bears against an abutment 76 provided at the extreme end of the cable. The spring maintains the cable taut.
- a mechanism for controlling the angular position of a tubular chute relative to a tubular conduit on which said chute is rotatably mounted comprising a support structure mounting the conduit in a fixed position, an elongate lever pivotally mounted intermediate its ends on said support structure, a helical groove formed in the outer surface of said chute, a cable, said cable having a loop formed at an intermediate portion and lying in said helical groove thereby encompassing substantially the entire periphery of said chute, said cable further having its ends crossing over and attached to the ends of said lever, and actuating means for pivoting said lever, said actuating means being operative to efiect rotation of said chute relative to said conduit by imparting tension to said cable which in turn imparts a turning moment to said chute.
- the mechanism according to claim 1 further comprising a spring located between one end of said cable and said lever for applying tension to said cable to maintain it taut and to absorb the inertial effects encountered in commencing rotation of said chute.
