To @ZZ whom it may concern: i

Be it known that we, THADDEUS GALVIN and JOHN GALVIN, citizens of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Gate-Hydrants; and we declare the 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, and in which- Figure l is a longitudinal section showing parts in elevation. Fig. 2 is a longitudinal section of the valve mechanism. Fig. 3 is a front elevation of the valve mechanism with adjacentpart of case in section. Fig. 4t is a rear elevation of the valve mechanism, show'- ing adjacent portion of the case in section. Fig. 5 is a horizontal section through the inlet-port with the valve closed.

It is the object of our invention to coinbin in a hydrant both a bottom and a side drip and an effective gate-valve that will tightly close the inlet-port when desired.

To this end A represents the casing of our hydrant, and A the inlet-port of the same.

B is the stem for operating the gate-valve.

C C are sliding disks, the former operating to close the inlet-port and the latter acting as an abutment-plate, against which to force the wedges D, used to set the valve-disk G firmly against the face of the inlet-port A. These wedges D, are suspended from the yoke F. This yoke is provided with a hook e, on which the disk C is hung by means of the elongated opening c on its upper end. The bolts e', usedto suspend the wedges from the yoke, may also be utilized to fasten the abutment-disk C to the yoke.

c are beveled ridges on the inner faces ot the disks C C', against which the beveled sides of the wedges rest.

c2 is a lug located on the inner face oi' the valve-disk C and bored to receive the spring c3. The end of the stem B, passing through the yoke E and fastened thereto by the pin l), may rest on this spring and partially compress the same. p

F is a yielding shoe or runner engaged to the edge of the valve-disk C by pins on the Serial No. 288,647. (No model.)

valve-disk entering corresponding grooves in the shoe or runner, as shown in dotted lines in Fig. 3, and held snugly against the face of the casing by a spring or springs f. The grooves in the shoe are closed at one end, so as to admit of the shoe being slipped on from the front of the disk aud prevent it from slipping olt at the back of the disk. This shoe F forms a valve for opening or closing the side drip d. Then the casing is made of iron, as it generally is, the inner face of the casing against which the shoe F rests may be lined with a strip of brass or equivalent material a', the same being fastened to the casing by a threaded lug a2, adapted to pass through the casing Vand secured at the exterior by a nut a3, run into the lug. The lug may be bored and thus serve as the drip a.. The strip or seat d may be additionally secured to the casing by providing the upper end witha ange d4 and passing a screw ai through it and into the casing.

G is the shank of the bottom drip, and is provided at its upper end with a right-hand thread and at its lower end with a left-hand thread, lor vice versa, the latter adapted to be screwed through the bottom of the casing. It Willbe readily seen that the threading of the shank in this way is an advantage in removing the drip for cleansing or repairing, since a piece of pipe or a tool may be screwed onto the top until it comes to a seat, and its further revolution will unscrew the drip-valve and it may be returned in like manner.

g is a lever forming the drip-valve stem and ulcrumed in the shank G and provided at oneend with `a cap or plug g', composed of rubber, lead,or othersuitable packing adapted to enter in or otherwise close the drip-orifice g2, which passes through the shank. By locating the opposite end ot` the valve-stem g slightly below and adjacent to the inlet-port it will be seen that when the main valve-disk C descends to its seat opposite the inlet-port the end of the valve-stem will be pressed down and the driporilice opened. Any suitable means-such as a small spring g3, located underneath this end of the Valve-stemmay be used for closing the opening when the pressure is removed by the raising of the valve-disk C.

I-I are inclined faces on the face of the casposition.

ing, against which the backs ofthe wedges D are adapted to slide, andv thus force the Wedges toward the center of the gate.

vI is a guide on which the abutment-disk C is adapted to slide and against which it is adapted to rest, being held firmly by the lugs c4, and .I is a groove in which the hook e is guided and which prevents the valve-disk C from disengaging from its hook.

The operation' of the mechanism will now be understood. 'The valve mechanism guided by the lugs c4, embracing the guide I and the hook e, traveling in the groove J, is lowered, the spring c3, compressed by the stem B, serving to keep the valve-disk C at its lowermost When the wedges I) reach the beveledv ridges H on the casing, they will be :gradually forced in, and their beveled sides "Mbearingfon thebeveled facesofl the disks will xcrowdthe valve-,disk out to a iirm seat against fi'the inlets"` port, the abutmentdisk bearing @against theguide I. The 'valve-disk C 'as it -comes tofits seat .will bear on the bottomdripvalve stem g and open the bottom-drip 'foriiice,'and this orifice will remain open until 'fthevalve-disk C israised,- when the spring g3 willoperate the drip-valve stem and close the "1- valve.

Theside-drip orifice a -is so located `relative to the yielding shoe F that the said shoe willcover. the end of the orifice, except lwhen the valve-disk C has reached its seat,

I"when it will leave the oriiice open and allow the drip to operate. yAs will be seen, the use fof=boththe bottom and side drips in connection with the valve-disk provides double se- -Icurity against freezing; ybut either the bottom or the side drip may bensed alone -in con-nection with the valve-disk. It will be observed f that the end of the lower-drip orifice is located above the bottom of the casing and on an incline,A thusv preventing stones or sediment f fromI collecting thereon.

; .'It will be observed that the springdoesnot vv"exert its action at the upper edge .of thedisk,

which would serve to tiltxthe disk outward the lug back ofthe valvedisk, so `as to act upon the valvewelldown toward the middle of the same, and at the same time the valvestem enters the top of said spring-cavity and holds the disk against tilting toward and so rubbing upon the valve-seat as it descends. It will also be observed that thearrangement whereby the valve-seat or water-inlet orifice and the drip-oritce are located contiguous to each other, so that both may be operated by the valve-disk itself, greatly simplifies the construction. It does away with the necessity of facing up two parts of the hydrant and obviates'the necessity of shaping and fitting and attaching to the valve-stem some special valve or shoe for closing-the drip-orifice.
