3 Claims. (Cl. 222-189)
My invention relates to a new and useful improvement
in a sprayer in which liquid is forced from a tank under
pressure through the action of a pump. The invention
relates to that type of sprayer in which the pump is re
ciprocated at one end in a well and particularly relates
tubular body 32.
A well 36 is provided and the lower end is constructed
in an internal diameter as at 37. This lower end is closed
by a disc 38 having a slot 39 formed centrally there
through and pressed upwardly at the central portion
thereof. Projected through this slot is a tubular member
41 at the upper end of which is secured a valve plate 49.
Secured to the lower end of the member 41 is a limiting
