UNTTE sTa PATENT VEDMUND BIG-ELOYV, OF SPRINGFIELD, MASSACHUSETTS.
Specification of Letters Patent No. 23,008, dated February 22, 1859.
To all whom it may concern:
Be itvknown that I, EDMUND BIGELow, of Springfield, in the county of Hampden and State of Massachusetts, have invented a new and useful improved self-measuring faucet for drawing a given quantity of liquid from a reservoir and discharging the same into a glass or other vessel; and I hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.
The nature of my invention consists in supplying a self-measuring faucet constructed as hereinafter described, with two vent pipes, one of which is in constant connection with the body of the faucet, and is useful mainly in allowing the air to escape from the faucet when in process offilling with liquid, while the other is useful only in supplying the faucet with air when discharging the liquid, and closed while the faucet is filling or standing full.
To enable others skilled in the art to make and use my invention I describe its construction and operation asfollows:
The faucet is made of metal.
Figure l is a perspective view of the faucet with sha-ft or feed pipe G by which it is attached to the reservoir to be drawn from, and through which it is filled. Fig. 2 is a longitudinal section of the faucet and feed l 1A A is'the cap to the faucet.
B B is the body.
C is a conical valve cast on rod D.
E is a head piece to rod D.
F is a valve made in two parts. The part K K is screwed to a bearing on rod D a leather packing is put on and the part L L is screwed up giving the valve a soft bearing.
M is the valve seat.
O is a port to pipe G.
P is a ground seat for valve C.
VI-I is a guide bar to rod D.
R is a packing boX to pack rod D as it passes through cap A A. i
.I is a spiral spring resting on guide bar H and valve C.
N is a vent tube running from the faucet to the height of the reservoir to be drawn from.
Rod D is hollow, and is furnished with two vents, one at Q and one at T. When rod D is at rest without pressure applied,
and valve F is closed, vent T stands closed,
nthrough pipe Gr and fills the faucet. Rod
D being then pressed down quickly by the hand valve C is brought firmly into its seat P, closing` port O, and stopping the flow of liquid into the faucet. At the same instant and by the same movement of the rod D, valve F is opened and vent T in rod D, is carried below cap A A, permitting a free entrance of air into the body of the faucet, and the liquid already in the faucet flows immediately into whatever vessel is placed below the faucet to receive it. The hand being removed from rod D, spiral spring J forces rod D back to its original position, bringing valve F, to a bearing `and opening port O, and closing vent T and the faucet again instantly lille-(the air escaping through pipe N) and may againbe emptied by repeating the pressure on rod D.
The advantage derived from vents Q, and
T in rod D is that they give an instani taneous and abundant supply of air to the faucet, and cause the liquid to flow into the receptacle placed to receive it, much more rapidly than it would if the air were supplied through vent tube N, because pipe N is always lilled with liquid to the same height as the reservoir isand on the other hand, if the air passage through rod D were left open into the body of the faucet after the pressure was removed from rod D and valve F was closed, the syrup or other liquid would be thrown out through that passage by the sudden refilling of the faucet and equally sudden expulsion of the air.
What I claim as my invention and desire to secure by Letters Patent is An improved self measuring faucet whose supply valve is closed and discharge valve pipe is shut off when the faucet is to be opened by a single movement, and When dsfilled or is standing full, substantially as l0 charge valve is closed and supply valve above described.
opened by a single movement produced by a. spring, and Which is supplied With a Vent EDMUND BIGELOW' pipe for letting out the air; and another Witnesses:
vent pipe for letting in the air when the A. L. SOULE,
faucet is to be discharged; Which last Vent H. D. SMITH.
