Vintage Garden Syringe Sprayers    

Back

In their simplest form syringe sprayers are made up of plunger fitting tightly in a tube called  the barrel. The plunger consists of a metal rod with a handle on one end and the piston assembly on the other. One end of the barrel (the front) has a nozzle through which the liquid is sucked into the syringe and through which it is expelled. The other end has a barrel end cap  (also called the plunger collar) through which the plunger rod passes. The barrel end cap unscrews so the plunger assembly can be maintained . There is an air vent (a small hole) near the barrel end cap, which allows air to escape/enter as the plunger moves within the barrel. The syringe is used by placing the nozzle end in the liquid pulling back the plunger to fill the syringe. The liquid can then expelled by pushing the plunger.

Basic Syringe Sprayer Additional Features

Several other features may be present or not depending on the model. Nozzles may include jet, rose or spray heads. These may be fixed in position or interchangeable. Spray heads may have replaceable caps having different size hole to give alternative spray intensity. Provision may be made to store these additional fittings on the barrel or drip sleeve. A removable bend may fitted to make spraying under leaves etc. easier. Removable fitting will have washers. If fitted, a drip preventing sleeve will to stop drips from the spray from running onto the users hands. A manufacturer’s label may be on the spray head, fitted a brass plate, punched into the barrel or applied as a transfer. A stuffing box filled with greased string may be fitted to stop any liquid which gets past the piston from running up the plunger rod. Internally there may be a spring on the plunger rod to provide some resistance when the plunger is nearly pulled back to its full extent. The air vent will be present, but may be hidden by the drip preventing sleeve. Rarely there may be a pipe from the air vent running part way down the barrel. This partly fulfils the purpose of the drip sleeve as it stops liquid which has got past the piston from running down the users hands. Handles fit on the end of the plunger rod and are normally as illustrated, but can also be ‘D’, ‘O’ or  ‘T’ shaped.
