THOMAS RICHARD GLEASON, OF DULUTH, MINNESOTA.

BALL- COCK.

SPECIFICATION forming' part of Letters Patent No. 615,386, dated December 6, 1898.

Application filed May 3, 1897.

To a/ZZ whom it may concern.-

Beit known that I, THOMAS RICHARD GLEA- SON, a citizen of the United States, residing at Duluth, in the county ofSt. Louis and State of Minnesota, have invented certain Improvements in Ball-Cocks and I do declarethe following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to ball-cocks; and it consists of a valve opened against the current of the outflowing water by means of the downward motion of the float-ball lever, aided by an adjusted weight suitable to open the valve under varying pressure of water by means of a positive and powerful reciprocating motion given vto the valve-stem by the action of an eccentric circular slot properly found and located in the headpiece of the float-ball lever; and my object is to provide a simple, cheaply-constructed, and durable valve closing with the outliow of the water, sure, safe, and noiseless in its operation, thus avoiding great annoyance from the noise and spray attending the action of other ball-cocks closing against the great pressure of the water, causing almost constant leakage, noise, siphonage, overflow, damage, and often repeated and expensive repairs.

I am aware that heretofore ball-cocks have been devised for opening against the outflow of the Water; also,that cams have been used on ordinary valves for opening and closing the same by hand; but I am not aware that there has been any ball-cock devised or made that has the new, valuable, and distinctive features herein set forth as my invent-ion.

Of the drawings, Figure 1 is a side elevation of my ball-cock in position, with the front wall of the tank partly broken away. Fig. 2 is an end elevation of Fig'. 1, and Fig. 3 is a vertical section of my ball-cock.

The saine characters of reference refer tothe same parts in the several figures of the drawings.

The lever-head 1 is preferably formed of brass about a quarter of an inch thick, and it is constructed with the circular slot 2, which is located eccentrically in relation to the ful- Serial No. 634,974. (No model.)

crum-pin 3, which passes through the stirrups 4t and retains the lever-head in its proper workin g position. Thelever-head is also constructed with the series of holes 5, the balllever Gis attached to the lever-head by means of the trunnion-pin'?, and the relative position of the float-ball 8 can readily be adj usted by placing the adjusting-pin 9 in any one of the series of holes 5.

The Weight l0 is constructed to slide freely upon the ball-lever 6 and is retained in any desired position by means of the thu mb-screw l1. The iioat-ball 8 is of the usual form, and the threaded thimble 12 is preferably riveted to the ball for the purpose of connecting it with the lever G.

The stirrups et are formed with or rigidly attached to the packing-box nut 13 and are enlarged at a to give suitable guide-bearing to the lever-head 1.

` The valve-stem 14 is provided with the vertical slot b, in which to receive the antifriotion-roller 15, which is retained in its position by the pin c. The ordinary packing-box 1G is to prevent any spray escaping while the tank 17 is being filled with water, and below the packi 11g-box the valve-stem is preferably reduced in size to present less resistance to the flowing water, and the valve d is held in position upon the stem by the nut @,and rests, when closed, upon its seat f.

The water is delivered in a downward course upon the bottom of the tank by the curved nozzle 18, and the wall of the cock has the flange g, the threaded `section h, and is provided with the iiange-nut 7c for removably attaching the ball-cock to the iioor of the tank, and the thimble-coupling 19 attaches the ballcock to the water-supply pipe 20.

Operation: The tank 17\ being lled with water to the line l, the Hush-valve is tripped by the operator and the Water-line descends with the iioat-ball 8, aided by the adjustable weight 10. As the weight descends the balllever c operates the lever-head 1, which, by means of the eccentrically-located circular slot 2, carries the valve-stem 14 downward by a positive motion by the action of the antifriction-roller 15, attached to the upper end of the stem, operating in the eccentric slot 2, thus forcing the valve d open against the current-pressure of the water coming in from IOO the rsupply-pipe 2O with a positive motion, governed and corresponding with the sinking motion of the ball. When the low level of the water is reached, the valve d is full open and the Water comes in rapidly, freely, and noiselessly, and when the Water-level has raised the ball nearly to a position to close the valve the slot 2 in the lever-head, in con- -nection with the close-fitting freely-Working antifriction-roller 15, prevents the great force of the water from closing the valve suddenly, and thus avoids theviolent pulsations, great noise, splashing of Water7 and injury and breaking of the ball-cock and bursting of the pipe, as is so very frequently the case in all other ball-cocks closing with the current of the Water.

The varying pressure of the water in the supply-pipe can be compensated readily by adjusting the weight IO in such a position on the lever 6 as will assure the opening of the Valve, and the veXatious bending and consequent breaking of the ball-lever is avoided by adjusting the lever in a proper relative position with the lever-head l by means of the adjusting-pin 9, the trunnion-pin 7, and the series of holes 5, located in the leverhead.

The heavy pounding which is so common in the ordinary ball-cock is entirely avoided by the center-line position of the Valve-stem with the trunnion-pin of the lever-head, and

this center-line position is maintained at all times of rest o'r action of the ball-cock. This feature adds greatly to the value and durability of my invention and enables me to construct a valuable ballcock, avoiding all form er objections to the ball-cock closing with the iiow'of the Water, which is by far preferable to those closing with the same, avoiding the almost constant leaking, noisy siphonage, and expensive repairs attending their use.

'What I claim as new,` and for which I desire to secure Letters Patent, is-

In a ball-cock the stirrups 4, the lever-head l, which is attached to stirrups 4 by means of the pin 3, and provided with the eccentrically-located circular slot 2, and the series of holes 5, in combination with the lever (5 provided with the float-ball 8, and adjustable weight 10, which is adj ustably attached to the lever-head 2, by means of the pin and series of holes 5, and the valve-stein 14, provided with the valve d, said valve opening against the outlowing current of the waterand closing with the same, as and for the purposes substantially as set forth.

In witness whereof I have hereunto set my hand in presence of two Witnesses.

THOMAS RICHARD GLEASON.
