Definitions

This invention relates to an oscillating spray apparatus.
a frame a first support means slidably mounted on said frame; stop means for limiting the travel of said first support means; a second support means slidably mounted on said frame; and a member for holding fluid discharge means connected to said first support means and said second support means; the arrangement being such that when a nozzle is mounted on said member and fluid is discharged therefrom, said first support means, said second support means and said member carrying said discharge means will move in one sense until said first support means engages said stop means, movement of said second support means relative to said first support means thereafter continuing so that said member moves into a position in which the thrust from said fluid causes said first support means, said second support means, said member and said discharge nozzle to move in the opposite sense.
the first support means and the second support means are bars which are substantially parallel to one another.
the means for limiting the travel of said first support means comprises abutment members mounted on said first support means.
the means for limiting the travel of said first support means comprises a housing.
means may be provided for adjusting the frequency of oscillations of said oscillating spray apparatus.
Such means may comprise a weight mountable on one of said first support means and said second support means.
At least one of said first support means and said second support means is provided with a plurality of holes for the selective attachment of one or more weights.
rollers are mounted on said frame for supporting said first support means and said second support means. At least some of said rollers are preferably provided with flanges for guiding said first support means and said second support means.
the apparatus 8 has a frame which comprises two vertical channel members l2, l4 each of which supports four rollers l6 a , l6 b , l6 c , l6 d .
a first support means comprising a first bar l8 is disposed between the rollers l6 a and l6 b whilst a second support means comprising a second bar 20 is disposed between the rollers l6 c and l6 d .
Each roller l6 a , l6 b , l6 c , l6 d is provided with flanges 22 ( Figure 3) which guide their associated bars l8 and 20.
the first bar l8 and second bar 20 are each prvided with a series of holes 24 which can be utilized to receive and hold weights to effect changes in the frequency of the oscillating action.
a weight 26 is shown mounted on first bar l8.
the holes 24 can also be utilized to receive and hold optional abutment members to limit the travel of the first bar l8 and the second bar 20.
abutment member 30 is shown mounted in end hole 28 on the right hand end of the second bar 20 whilst another form of abutment member 50 is shown mounted in the end holes 28 of the first bar l8.
a member 32 extends between the first bar l8 and the second bar 20.
the member 32 is piovtably mounted on the first bar l8 via a pin 34 which passes through a hole in the upper portion of the member 32 and is secured fast in the first bar l8. Washers 35 are provided to either side of the member 32 as shown in Figure 4.
the member 32 is also pivotably mounted on the second bar 20 via a pin 36. However, the lower portion of the member 32 is provided with a slot 37.
a spray 46 of fluid is discharged from a nozzle 48 secured to the member 32.
the spray 46 makes an angle ⁇ with respect to the vertical and consequently there is a reaction force F having a horizontal component Fx which urges the first bar l8 and the second bar l8 to the right as viewed in Figure 5.
the first bar l8 When the first bar l8 reaches the rightmost limit of its travel ( Figure 6) it abuts the upper portion 42 of the housing 40. However, the second bar 20 continues to move under the influence of the spray 46. As the second bar 20 moves relative to the first bar l8 the angle decreases to 0°. At this point the horizontal component Fx of the reaction force F is zero. However, the inertia of the second bar 20 carries it to the position shown in Figure 7 where the second bar 20 abuts the lower portion 44 of the hpusing 40. The thrust of the spray 46 then drives the first bar l8 and the second bar 20 to the left as viewed in Figure 7 until it reaches the position shown in Figure 8 where the first bar l8 abut the upper portion 42 of the housing 40. As before, the second bar 20 continues moving to the left until it abuts the lower portion 44 of the housing 40. The cycle is then repeated.
housing 40 can be replaced by stops on the first bar such as abutment member 50. Stops such as abutment member 30 on the second bar 20 are optional since the overall movement of the second bar 20 with respect to the first bar l8 is limited by the member 32 and the slot 37.
