Specification of Letters Patent No. 141, dated March 11, 1887. 

To all whom it may concern: 

Be it known that I, Samuel Adams, of 
Townsend, in the county of Middlesex and 
State of Massachusetts, have invented a new 
5 and useful improvement in connecting lead 
and other pipe with the barrels of wooden 
pumps and in letting off the water to pre- 
vent freezing; and I do hereby declare that 
the following is a full and exact description. 

10 The nature of my invention consists in 
connecting lead and other pipe with the bar- 
rels of wooden pumps so as to form an air 
tight junction by means of soldering a flange 
to the pipe, and a socket, to receive the lower 

15 box, to said flange, and bolting said flange 
to the wooden barrels, and in letting off the 
water by means of a lever valve to the lower 
box, opened by a vertical projection in the 
upper box. 

20 To enable others skilled in the art to make 
and use my invention, I will proceed to 
describe its construction and operation. 

See the drawings annexed, Figure 1, A 
represents the pump entire, two feet and two 
25 inches in length. Fig. 2, A represents the 
pipe which is to be connected with the pump 
at the bottom, B represents a pedestal of 
oak or other hard wood, of an oblong square 
form, projecting on two sides about three 
inches from the base of the pump, by means 
of which the pump is made fast to the floor 
or platform, C represents a lead or other 
metallic flange about one eighth of an inch 
thick, and large enough to cover the bottom 
of the pump. Through the center of said 
pedestal and flange, the pipe A passes and 
is soldered to said flange so as to make the 
upper end of the pipe even with the upper 
surface of the flange. Directly over the 
end of the pipe, on the upper surface of the 
flange is soldered a lead or other metallic 
socket, D, about three inches deep, the bore, 
or interior surface of which is in the shape 
of an inverted truncated cone, two inches 
and one fourth in diameter at the top, and 
one inch and three fourths at the bot- 
tom, or point of junction with the flange; 
the outer surface of said socket is cylindri- 
cal, two inches and a half in diameter at 
both ends. This socket is passed into the 
bore of the pump (which is 2^ inches in di- 
ameter) at the bottom until the aforesaid 

flange, which has a layer of soft leather, or 
other similar substance upon it, comes in 
contact with the bottom of the pump, 55 
against which it is made to press at pleasure, 
by means of the aforesaid pedestal, B, 
drawn up against it by four bolts, as seen in 
Fig. 1, passing either up or down, through 
the shoulder corners of the pump's base, and 60 
tightened by nuts or keys. E represents the 
lower box fitted water tight into the afore- 
said socket, where it lodges when dropped 
down the bore of the pump. 

The water is let off to prevent freezing by 65 
raising the pump handle to its greatest 
height, thereby causing a projection in the 
bottom of the upper box to open the valve 
of the lower box. Said valve of the lower 
box, which I call the lever valve, consists of 70 
the usual leather, as long as the upper diam- 
eter of the box, with a lever of some hard 
wood, of the same length, attached to its 
upper surface, and is fastened to the upper 
edge of the box in the usual way (the boxes 75 
being made of wood). 

The form and nature of the lever valve, 
and its operation, will be best understood by 
an inspection of its drawings. Fig. 3 in 
which A represents the leather, B represents 80 
the lever, and G represents the point on 
which the lever turns when its small end is 
pushed down by the aforesaid projection 
in the bottom of the upper box, as seen in 
Fig. 4, in which A represents the lever valve 85 
of the lower box, opened by B, the aforesaid 
projection in the bottom of the upper box 
pushed down upon the small end of the 
aforesaid lever by raising the pump handle 
to its greatest height. 90 

The construction aforesaid effectually pre- 
vents the water in the pipe from wasting by 
the admission of air at the point of junction 
of the lead, (or other metal) and the wood; 
when the pump is not in operation and the 95 
pump handle being raised to its height opens 
the valve of the lower box as aforesaid and 
lets off the water from the pump and pipe 
so as to prevent the damage and inconveni- 
ence of freezing when the temperature is 100 
such as to freeze water. 

What I claim as new and of my own in- 
vention, is — 

The connecting of lead and other pipe 



with wooden pump barrels so as to form an 
air tight junction, by means of locating the 
lever box in a socket connected with the 
pipe as aforesaid, within the pump barrel, 
5 and other means as aforesaid; and the let- 
ting ott' of the water to prevent freezing, by 
means of the lever valve in the lower box, 

opened by the projection in the bottom of 
the upper box, all as aforesaid.
