IMPROVEMENT 1N VALVES.

.TO ALL WIIOM IT MAY CONCERN:
Be it known that I, JOHN BRIGGS, of Roxbury, inthe county of Norfolk, and State of Massachusetts, have invented certain new and useful Improvements in Valves; and I do hereby declare that the following, taken in connection with the drawings which accompany and form part of this specification, is a description of my invention su'lcient to enable those skilled in the art to practise it.
Formany uses it is very desirable to employ a valve which moves with ease, as to opening or shutting the aperture which' it controls. Valves have been made for this purpose, but they have not been of an organization so simple and inexpensive as to secure their generall introduction, and some of them have had defects, such as being rendered leaky by thermal changes, and being diieult to grind tight after wearing so as to leak.
I have shown in the drawing an illustration of my invention, in th-e form which it will ordinarily be made to assume, the drawing being a sectional elevation of what is commonly known as a globe-valve, modified so as include my invention. Either end of the valve-case may be used as the inlet, the other end, of course, being the outlet. The two 'ends of the ease are separated by a kind of pocket partition, shaped like the letter U, and cast integral with the-entire case, the pocket being so located within the case that a taper valve-seat opening, concentric with the axis of the stuing-box, may be formed in both walls of the pocket, in which seat a taper' plug-valve provided with a stem is made to t, and which operates, not by rotation on its axis, but by reciprocations in the direction of the length of its axis.
, The outer case of the valve is marked a, and in this description l', will be considered the inlet, and e the outlet. The material forming the pocket is marked d, the taper plugvalve e, its stemf, and the stem packnga -box g. The case of the valve is provided in the line of the stemf, and opposite the standing-box, with a, serewplug, L, throughwhich the taper plug-valve eis introduced to its seat. On the neck z', adjacent to the stuingbox g, and forming an integral part of the case a, is located a ring, 7c, provided with a fulcrum-post, Z, and fixed in position on the neck z' by the set-screw m. The valve-stemfis slotted to receive the short arm of bent lever n, which is pivoted to the fulcrum-post, and through which motion is communicated to reciprocate the valve. s It will be obvious by slacking the set-screw m that the ring 7c, its fulcrum-post, and the lever n, can be turned about the neck z', thus in many cases rendering it easy to make the connection with the valve-stem from any direction. The linesin red on the drawing show a change of position of the fulerum-post of one hundred and eighty degrees. In drawing the valve is represented as closed upon its seat, and it is opened 4by moving toward the screw-plug or cap h, in which ease the inlet being at b'the directions of the currents will be those indicated by arrows marked on the drawing.
The valve constructed as described is nearly but not fully balanced, and when the end 6 is` used as the s inlet, the dilierence in the pressure exerted on the valve, caused by its taper form, is exerted to keep the valve upon its seat. If thc end e should be used as the inlet, then the difference in the pressure on the valve would be exerted to keep it oli` from its seat. When of sufficient importance this want of equilibrium may be compensated by properly weighting lever I claim the valve,'construeted and arranged with the pocket partition between the outlet and inlet, and with the taper plug-valve, substantially as described.
Also, in combination therewith, the changeable fulcrum-post and lever, for the purpose specified. JOHN BRIGGS.
