Specication of Letters Patent.

Patented oct. 1e, 1906.

To all, whom it may concern:

Be it known that I, AMos K. BUTLER, a citizen of the United States of America, and a resident of Skowhegan, in the county of Somerset and State of Maine, have invented certain new and useful Improvements in Valves, of which the following is a specification.

This invention relates to certain` new and useful improvements in valves, and more particularly to ball-cock valves, although, as

Wlll be readily understood as the description proceeds, it is applicable to other uses and is not restricted in this description or in the claim to its use as a ball-cock valve.

The present invention has for its objects to rovide an all-metal valve which shall be perfectly tight Without packings, thus rendering it eXceedin ly durable, and, further, it is so constructe as to be noiseless as the Water passes therethrough. Bein submerged, it has equal pressure in al directions, gives a free flow to liquids or gases, is easy to operate under high Water-pressure, and can be manufactured at minimum cost. It can be used on a main from a pumpingstation without transmitting the noise occasioned by pumping.

Other objects and advantages of the invention Will hereinafter appear, and the novel features thereof will be specifically deined by the appended claim. l

The invention in one of its modes of use is clearly shown in the accom anying drawings, which, with the numerals o reference marked thereon, form a part of this specification, and in which* l Figure 1 is a substantially central vertical section through the bottom of a tank, showing the application of the invention to such use. Fig. 2 is a detail, partly in plerspective and partly in section, showing t e plunger and its coperating member.

Like numerals of reference indicate like parts in the different views.

As above stated, in the present instance I have chosen to illustrate my present invention as applied to a tank for use as a ball-cock valve, an I shall now so describe it.

Referring to the details of the drawings, 1 designates the bottom of a tank of usual construction and to Which the valve may be applied either at the bottom, as shown, or in any other preferred position.

2 designates a ortion of the main to which is connected the olloW metal casting or member 3, which in this instance is shown as provided with the screw-threads 4 .for a coupling V 5 in a well-known Way. This castin or member 3 is formed with lugs or the liie 6 for the reception of its attaching means, as 7, in this instance the said lugs lbeing shown as attached to the bar or plate 8, which is secured to the Wall 1 of the tank, as by the bolts and nuts 9; but it is evident that this is but one of the various Ways in which it may be attached. The hollow casting or member 3 is further formed with the exterior screwthreads 10 and with the Wedge-sha ed end portion 11, which may or may not e truncated, asA shown, and this Wedge-shaped end portion is provided With a plurality of ports 12, although I should consider one port or opening an e uivalent, and it may serve under some con 'tions 13 is a casing having a portion 14 provided Withinterior threads 15, engaged With the threads 10 of the member 3, as shown, the said portion 14 being shown as en aged Within an openingl 16 in the Wall 1 of t e tank, a1- thoughthis is not necessary.

17 is the plunger movably mounted within the casing 13 and designed to be actuated in any suitable manner, dependent upon the circumstances and use to which the valve is put. In the present instance it is shown as adapted to be actuated by the float-arm 18,

carrying the float 1 9, disposed Within the tank and designed to be actuatedby the rise and fall of the Water in the tank in a manner which will be readily understood. The plunger 17 has a Wedge-shaped socket or cavity 20,as seen best in Fig. 2,. to receive the wedge-shaped end of the member 3, as seen in Fig. 1.

The casing 13 should be provided with a suitable aperture or apertures for the outflow of the Water. In the present instance I have shown it as provided with a plurality of them, which may or may not correspond with the number of ports or openings 12 in the Wedge-shaped end 11 of the member 3, and for -the purpose of conducting the Water laterally as it flows through the openings or ports 12 I provide the casing near its `inner ICO . end with nipples 21, into which are screwed the short nozzles 22, and in order to rovide increased ca acity for the water wit 'n the casing the 'atter is enlarged interiorlyl at 5 points about or opposite the said nipples, and

consequently opposite the ports, such enlargement being seen in Fig. 1 at 23. These features of the construction, however, are v. not necessarily resent, or other means for 1o accomplishing t e end subserved thereby ma be employed in their stead.

rlyhe operation will be apparent from .the foregoing description, especlally when taken in connection withthe annexed drawings, it

15 being understood that as the float rises the lunger is lowered and when the plunger is Forced down to its limit the lower ortions of the walls ofthe wedge-shapedsocet or cavity close over the ports 12 in the member'3 2o and completely shut off the flowfrom the main into the tank. As the water in the tank falls' the float falls and gradually moves theplunger to disclose the ports 12, and the water is again admitted.

25 As seen clearly in both views, the member 3 at the base of its wedge portion'1 1 is formed with the shoulders 11, against which the lower ends of the tapered sides of the plunger abut to limit the movement of the plunger and prevent its becoming unduly wedged 3o thereupon. j f

'The proportionsof'the parts and the means for 'operatmg the plunger may be varied, and otherlike changes'may b'e made without affectin the operativeness of the device, and 3 5 modilgcationsl in detail'may be resorted to without departing from the spirit of the invention -or sacrificing any of its advantages.

What is claimed as new is In a valve, a Xed member with exterior 4o threads for a coupling, an integral wedgeshaped end with ort and threads intermediate said end and t e first-named threads, and securing-Han e intermediate the iirst and lastl named t eads, a plate restin on said 45 flange combined with a plunger aving a wedge-shaped socket, and a casing inclosin said plunger and securedl to the last-named threads and resting on said plate.

Si ed by me at Skowhegan, Maine, this 5o 8th ay of April, 1905.
