Abstract: An external by-pass circuit for a positive displacement pump includes a flow diverter valve coupled to the pressure port of the pump. The flow diverter has an end coupled with a high flow output and another end coupled with a low flow output. The low flow end includes a by-pass arm coupled to and input flow fitting. The flow diverter valve further includes a ball valve to direct fluid to either the high flow or low flow output. The input flow fitting is coupled to the suction port of the pump at the one end and couples with a fluid source at the other end. The input flow fitting includes a flow control arm which includes a needle valve to selectively control flow within the flow control arm. The flow control arm also includes a by-pass fitting fluidly coupled with the by-pass arm of the flow diverter valve.

Abstract: A hand-held spreader is provided having a base with a mechanism for spreading particulate material response to turning a hand crank. The base is universally attachable to hoppers of different types which provide particulate material to the base for spreading. Different types of hoppers when attached to the base can adapt the spreader to spread different particulate material, such as of seed or salt. Teeth may be provided along upper edge of the hopper for use in scooping up particulate material into the hopper. Another type of hopper which can be attached to the base has a closed top end to provide a sealed container of particulate material, and has a sealing member releasable from the hopper to allow flow of particulate material from the hopper to the attached base.

Abstract: A sprayer system having a trailer, which is pulled by a tractor or other tow body, and has a tank carrying liquid to be sprayed and a spray head. The trailer has a peristaltic pump mounted on a frame and driving pumping power from the wheels of the trailer so that the sprayer is self pumping when the trailer is pulled. The peristaltic pump provides a smooth flow by providing a multiplicity of pulses of liquid produced by the pump from the rotation of the trailer wheels by wrapping the compressible tube of each pump around an assembly of rollers which are rotated by drive wheels. The tube is wrapped at least 360° around the rollers and is held stationary by being connected to fixed outlet and inlets of each pump. The tube lies side by side on at least one of the rollers of each assembly and overlaps that roller.

Abstract: A manually operable spreader which can be moved from behind on a surface is especially suitable for distributing salt and other particulate materials which tend to conglomerate or clump in a hopper of the spreader. Wheels are mounted to a frame also support the hopper. A horizontal drive shaft between the wheels is coupled to rotate a vertical shaft. A distributor below the hopper rotates with vertical shaft rotation to distribute particulate material which drop via openings in the bottom of the hopper. The vertical shaft extends via a hole in bottom of hopper and carries at the top thereof an auger having a helical vane. The auger is rotatable with the vertical shaft as the spreader is moved on its wheels. The auger circulates the particulate material in the hopper as the spreader moves while directing material in the hopper towards the bottom thereof.
Abstract translation: 可以从表面后面移动的可手动操作的吊具特别适用于分散倾斜于聚集或聚集在撒布机料斗中的盐和其它颗粒材料。 车轮安装在框架上也支撑料斗。 轮之间的水平驱动轴被联接以旋转竖直轴。 料斗下方的分配器随垂直轴旋转而旋转，以分散通过料斗底部的开口落下的颗粒材料。 垂直轴通过料斗底部的孔延伸，并在其顶部承载具有螺旋叶片的螺旋钻。 当吊具在其车轮上移动时，螺旋钻可随垂直轴旋转。 螺旋推运器在料斗移动的同时将颗粒材料循环在料斗中，同时将料料朝料斗的底部引导。

Abstract: A chest-mounted spreader system includes a hopper for receiving particulate material and a base assembly mounted to the hopper. The base assembly has a base unit having a base plate and rotatable shaft. An electric motor is coupled to the shaft to drive rotation of the shaft. An impeller is mounted on the shaft proximate the base plate. A shroud has a partial sidewall affixed to the base plate thereby defining an impeller cavity. The impeller cavity includes a discharge opening opposite the partial sidewall and the impeller is received within the impeller cavity. A shroud opening is in fluid communication with the hopper so that particulate matter passes from the hopper to the impeller. The electric motor is powered to rotate the shaft and the impeller to disperse the particulate matter through the discharge opening.
