Abstract: A self-propelled lawn and garden spreader that can be used to apply granular and/or liquid materials to both wide and narrow areas at a constant rate of application per unit area at different ground speeds, such as at a relatively high speed when the operator of the spreader is riding on the spreader, and at a relatively low speed when the operator is walking behind the spreader. The spreader generally includes a frame on which a suitable motor is mounted, wheels mounted to the frame with at least one of the wheels being driven by the motor, and a unit for controlling the ground speed of the spreader, including at least two forward speeds. The spreader further includes a material storage compartment mounted to the frame for containing a material. The material storage compartment has an outlet through which the material exits the material storage compartment and is delivered to a dispenser unit that broadcasts the material outwardly, including away from the sides of the frame.

Abstract: A tension-actuated submerged dispenser for discharging a liquid of one composition into liquid surroundings constituted by a liquid of a different constitution is useful for unattended employment to maintain a certain quality of composition in the surroundings. On the other hand, the quality of composition of liquid in the dispenser can be jeopardized if liquid from outside the container is allowed in, as has been the case with some earlier known submerged dispensers which employed a displacement liquid. In order to develop the necessary pressure to express a liquid through an orifice in a submerged container into which no such displacement liquid is allowed entry, a system of actuating a reduction of enclosed volume by means of tensing a container between opposed end-effectors has been developed. The source of pulling force can be either an externally attached weight or float, or a dispensed liquid which is differentiated as to specific gravity from that of the liquid surroundings.
