ALBERT S. NEWTON, F PROVIDENCE, RHODE ISLAND.

SANITARY-DBINKING-FOUNTAIN-SUPPLY SYSTEM.

Specification of Letters Patent.

Patented J an. 36, 1917.

Application filed June 21, 1916. Serial No. 104,885.

To all whom it may concern:

Be it known that I, ALBERT S. NEWTON, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Sanitary Drinking Fountain Supply Systems, of which the following is a specification.

My invention relates to sanitary drinking fountains, and has for its essential objects the reduction of the water pres-sure from the city main or other source of water supply to automatically control the operating pressure in the system so as to compensate for such irregularities of water pressure as exist in mains, or which are occasioned by drawing water from some branch pipe connected with the system; to maintain the drinking stream at a substan tially constant or uniform height; and to vary such uniform height at will.

Other important objects are to insure simple and non-leakable structure.

To the enumerated ends essentially my invention consists in such parts and combinations of parts as fall within the scope of the appended claims.

In the accompanying drawings which form part of this specification, Figure 1 is a side elevation of the system embodied in its preferred form, Fig. 2, an elevation of the same taken at 180 degrees from that of Fig. 1, showing a portion of the tank in central vertical section, Fig. 3, vertical central branches,

section of a part of tank showing the uppermost position of the float, and Figs. 4 and 5, sections on lines 4-4 and 5-5 respectively of Fig. 1.

Like reference characters indicate like parts throughout the views.

My system in its present and preferred form comprises a supply pipe 7 extending from the main or other source of water supply 8 to a conduit or pipe represented in a general way by the reference numeral 9. The latter has a vertical section 11 from an intermediate portion of which the pipe 7 and whose upper end 12 enters and supports the base 13 of a tank 14. The conductor 9 has also a horizontal section 16 connected with the end of section 11,

' and terminates in a vertical section 18 carrying the discharge nozzle 19.- In the portion 16 of the pipe 9 is a valve casing 21 in which is the valve 22 whose stem 23 in this case has a squared head 24 to receive a wrench. In the portion 18 of the pipe 9 adjacent the nozzle is the casing 26 of a valve 27 preferably of the spring returned type, and operated by a handle 29 on its stem 30. In the pipe 7 is a valve case 32 in which is a valve 33 to whose spindle 34 is fixed an arm 35 to whose end is pivoted a block 37 provided with an opening 38 for a purpose to be later set forth.

The tank 14 comprises in addition to its base 13 a body 41 and a removable cap 42. The former has a thread 43 to receive a thread 44 upon the side wall 45 of the cap. The top wall 46 of the latter has a central opening 47 bounded by depending tubular projection 48. Within the tank is a hollow metallic cylindrical float 50 of slightly less diameter than the internal diameter of the tank having in the center of its upper end face a conical guide projection 51 around which and resting upon the top of the float is a rubber washer 52. Attached to the top of the member 51 is flexible member 54 which passes over a pulley comprising a standard or hearing 55 in which is a pintle 56 on which is loosely mounted a wheel 57 over whose grooved rim passes the flexible member. I Vire guards 58 are fixed in the pintle.

A conical shaped spool 60 slidable on the member 54 has a thumb screw 61 engaging the latter to adjust the spool to any desired height thereon. The reduced upper portion of the member 60 enters the opening 38 of the member 37 and elevates the arm or lever 35 when the float 5O descends. When the latter ascends the arm 35 follows the spool downwardly by gravity. This vibration of the float oscillates the valve 33 thus increasing or diminishing the flow of water through the pipe 7.

The course of the water is through pipes 7 and 9 to or through the nozzle 19; and from the pipe 7 upwardly through the pipe portion 12 into the chamber 63 of the tank to support the float 50. An increase in the force of the water through the pipe 7 elevates the float and effects the depression of the arm 35 thus diminishing the force of the flow through the pipe. The opposite effect on the valve 31 occurs when the original current diminishes in intensity. The nozzle stream is thus maintained at substantially uniform height regardless of the intensity of the flow from the main8 or through the supply pipe 7.

The use of the valve 22 is to determine or fix the nozzle stream at any desired height. A uniform high stream or uniform low stream may be thus attained. This valve is seldom operated, however, after initial setting of the same.

The valve 27 is purposed merely to open and close the nozzle.

It will be observed that if the float 50 is forced into its uppermost position as shown in Fig. 3 by an excessive force of water, yet no leakage or emission of water from the top of the tank takes place because the packing ring 52 tightly engages the projection a8. The projection 51 serves, in conjunction with the projection 48, as a guide to the float.

The adjustment of the member 60 on the flexible member in conjunction with the arm 35 is for the purpose of adjusting the height of the float 50 to the opening of the valve 33.

I claim 1. In a pressure regulator, the combination of a tank, a conduit connected with the tank and leading to a point of discharge, a supply pipe projecting from the conduit, a rotary valve in said supply pipe, an arm on the valve, a float in the tank, a flexible member connecting the float and arm, means on the flexible member for adjusting the arm relatively to said flexible member, a detachable head to said tank having an in wardly-extended tubular projection, and

. leak-preventing means carried by the float and cooperable with the inner end of said projection.

2. In a pressure regulator, the combination of a tank, a conduit connected to the tank and leading to a point of discharge, a supply pipe connected to the conduit, a

valve in the supply pipe, a float in the tankoperatively connected with the valve to equalize the pressure of water at the point of discharge,a depending tubular projection within the tank, means on the float cooperable with said projection to guide the float, and leak-preventing means carried by said float and cooperable with said projection.

3. In a pressure regulator, the combination of a vertical tank provided with an opening in its top, a tubular downwardly directed projection in the top of the tank surrounding the opening, a float in the tank, a conical projection upon the top of the float adapted to enter the opening, a packing disk on the float at the base of the conical projection adapted to engage the end of the tubular projection when the float is in its uppermost position, a pulley on the tank adjacent the opening, a conduit leading from the lower end of the tank to a point of discharge, a supply pipe branching.

from the conduit, a valve in the supply pipe, an arm on the valve, and a flexible member extending from the conical projection to the arm and engaging the pulley.

i. In a pressure regulator, atank, a conduit connected therewith, a supply pipe connected with said conduit, a float in the tank, a valve in the supply pipe, an arm connected with said valve, a flexible connection between said float and arm whereby the force of the flow through the supply pipe is automatically controlled by said float, and cooperating means on said float and tank within the latter for guiding the float and preventing the leakage through the top of the tank.

In testimony whereof I have aflixed my signature.

ALBERT S. NEWTON.
