To all whom it 451::

Be it known that ,I, LOUIS B.

Trton'n, a

. citizen .of theUnitedStates, of Boston, in

'the county of Suffolk and State of Massachusetts, have invented a new and useful Imrovement in Ball-Cocks, of which the folowing, taken in connection with the accompanying drawings, is a specification.

My invention relates to improvements in ball-cock apparatusfand'eonsists in important changes and additions which may be best understood by reference to the full description in c'onnectionlwith 'the accompanying drawings, .in which- Figure 1 is a side elevation of my apparatus; Fig. 2 is a front elevation of the same; Fig. 3 is a vertical longitudinal section taken through the center; Fig. 4 is a cross-vertical section taken on line l4= of n the drawings A re resents the body part of the cock and H l-I the projections extending downward and outward for convenience in fastening the cock to the walls of the tank. The art A is for connection with the service plpe. The head A of the cock has within it a rotatable key B which is held in place by the screw cap A which also holds a suitable packing A for preventing leakage; the stem B is used for turningthe key B-when it is desired, to out oi the -flow of water for repairing or for. any other purpose. This key B is removable so that its seating face can be repaired and the interior of 'the cock can be cleaned, that is, freed from sediment, etc. The lower end of the key B has a water way W which connects with the" water way W when the apparatus is in working order. It will be noticed that the water way W is much smaller than the way W. The capacity of the way W may be varied in different keys so as toadapt the device to different heads ofdwater; for instance, thehigher the pressure of water in the service pipe the smaller the water way in the key B will be'made;

. thus the same body part of the cock'may be used for different pressures.

The gravity piston C drops by its own weight and also by the force of water pressure at its upper end when not held up by the action of the float; the upper end 0 the piston C has attached by a screw or other-" wise a suitable packing P as shown in Figs. 3 and 4. The packin P is set in a recess made in the upper en of the piston O. In'

, the drawings Figs. 3 and 4, the piston is shown in the position it occupies when the cock is open and the water flowing.

- The action of the float or ball (not shown) is as follows: hen the water rises in the tank the stem C of the float which goes through the tubular socket L and whichis attached to the arm L and thereby to the finger C which swings on the pivot (3*, causes fin er C to depress the outer end of the short ever C, pivoted on C and causes the inner end to act against the lower end of the piston.C and force it upward, thus brin ing the packing P in contact with the lower end of the key B and closing the water way WV, that'is, regulating an preventing the flow of water into the tank,

a set screw D working through a bridge N serves as an adjustable stop or gage for the movement of the terminal finger piece C thus controlling the .movement, of the float downwardly; a check nut D holds the'adjusting screw D in the desired position. By

releasing the set screw D to its limit the finger C will fall so as to let the piston C drop out for the purpose of repalrlng the packing P. By turning the set screw D down to its limit it forces the finger C down onto the lever C which pushes the piston C against the seat at the bottom of the key B, and closes the cock, thus making a shut-off independent of the float, and closing the cock when'the float and stem are detached for re airs.

hen the flow of water leaves the key B it passes intothe water way W Fig. 4, and thence downward into the pipe K and thence into the tank.

The pipe F is attached to the screw plug F and serves as arfa'rchamber to relieve the shock from the sud n checking of the flow of water. The screw plug F has a hole through its center as indicated in Fig. 3.

For convenience in adjusting the workmg length of the stem C of the float (not shown) I have the following-described device: A

short arm L extends laterally from the part Thus when it is desired to' thumb screws and R. and can be used to release the said terminal finger and lever.

The arms M are united and kept rigid by the bridge N.

Claims.

1. In a ball-cock apparatus, a body part which has screw connections for an inlet and outlet pipe, respectively, and a main water way, a valve casing, a head having a ground seat and containing a key, an unattached gravity piston valve with a valve packing (p) operating in the said casing, the key having a passa e therethrough and a projectin seatin ace, two side arms which extend rom an are attached to the said body art, a separate finger and lever pivotally astened between the said side arms, a float and stem, said finger and lever operated by L said float and stem to cause the valve to seat on the said face, a stationary bridge on the said side arms, a set screw in sa d bridge operating on said finger, the key being a apted to close said main waterway, to allow the floatand stem to be detached for repairs; as and for the purpose set forth.

'2. In a ball-cock apparatus, a body part which has screw connections for an inlet and outletpipe, respectively, and a main water way, a valve casing with an opening at the top and bottom, a head having a round seat and containing a key, an unattac ed ravity 'on the said face, a stationary bridge on the in said casing, the key bein adapted to close said main waterwa to al ow the float and stem to be detache for repairs, as and for the purpose set forth;

3. In a ball-cock apparatus, a body part which has screw connections to an inlet and outlet pipe, respectively, and a main waterway, a valvecasing w1th an opening at the top and bottom, a head having a ground seat and containing a key, an unattached gravity piston valve with a valve packing (p) operating in the said casing, the ke-y'having a passage therethrough and a seating face that projects into and below the said top opening of said casing, two side arms that extend from and are attached to the said body part,

a separate finger and lever pivotal 1y fastened between the said side arms, a float and stem, said finger and lever operated by the said float an stem to cause the valve to seat on the said face, a stationary bridge on the said side arms, a set screw in said bridge being adapted to control the movement of the said finger, lever and valve, in combination, to hold said valve in said casing and to allow said lever totilt so that the said valve can drop out of the said bottom 0 ening of said casing, the key bein ada te to close said main waterway to allow t e valve to be detached for repairs; as and for the purpose set forth.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses, on this twelfth day of December A. D. 1907,

LOUIS B. THORE.
