e I PUM P.
SPECIFICATION forming part of Letters Patent No. 244,641, dated July 19,1881.
Application filed November 1, 1580. (No model.)
declare the following to be a full, clear, and
exact description of the same, reference being had to the accompanying drawing, and to the letters of reference marked thereon.
This invention relates to that class of pumps known as bucket-plungersfl. and it consists, mainly, in certain special details of construction, fully described hereinafter, by means of which access to the valve-chamber is more readily obtained and the cost of production is reduced.v
In-the drawing is represented a vertical sectional elevation of the base portion of a pump havingmy improvements applied thereto.
To enable others skilled in the art to make my improved pump, I will proceed to describe fully the construction of the same. 7
A represents the base portion of the pump. 7 B represents the lower valve, and b the valveseat provided with the guide-stem b. The valve-seat is itself supported, it will be observed, by the division-wall or diaphragm b 0 represents the upper valve, and c the valveseat provided with the guide-stem c. The valveseat itself, it will be observed, is supportedby the division-wall or diaphragm 0 The opening in the diaphragm .0 is larger in area than the valve below it, and hence the latter may be readily inserted or removed through the former when desired.
D represents a bolt extending downward through the air-chamber d, the lower end of which is adapted to bear upon the upper end of the guide-stem ot' the upper valve-seat.
d d represent screws or bolts, by means of which the air-chamber is removahly secured to the baseportion of the pump.
Some of the advantages of the described removed. The upper valve-seat, also, may be tightened, ifdesired, without removing the airchamber, by simply screwing down the bolt D.
Having thus fully described my invention, what I. claim as new, and desire to secure by Letters Patent, is
In combination with the upper valve-seat, 0, having the guide-stem c, the bolt D, the upper end of which extends through the top of the air-chamber, and the lower end of which bears on the guide-stem c, the construction being such that the valve-seat may be tightened without removing the air-chamber, and also be securely held from displacement when struck by the lower valve in the upward movement of the latter.
This specification signed and witnessed this 22d day of October, 1880.
