ABRAHAM OOA'IES, OF WATERTOWN, NEW YORILVASSIGNOR, FOR ONE- Y HALF, TO JAMES MARTIN HUNT, OF PLACE.
f Letters Patent No. 97,881, dated `Decfmzbe'r 14, 1869,;v
IMPnovnMEn-'r I`1-rV VALVES ron WATER-ENGINES.' l w l l 'The Schedule referred to in theseLetters Patent and making part of the same.
To all whom it may confcern: v
Be it known that I, ABRAHAM Gowns, of Watertown, in the State of New York, have invented a new and useful Improvement in Valves for Water-Engines; and I do hereby Ydeclare that the following is a full,
` y clear, and exact description vof the same, reference being had to the accompanyingdrawings, andletters of reference marked thereon, making a part of this specifi- Figure 1 is a plan view of my improved valve;
`Iligure 2 is a transverse vertical section, in the line l :r-x, fig. 1; and
.llledawings reIer to like parts. is an` improvement upon the valve shown in they water-engine patented by Coates and Osborn, May 12, 1863, which valve was simply a dat plate, with a transverse disk on each end.
The improvement consists in providingthe `said valve with certain additional surfaces, for thepurpose of relieving it from the pressure of the water which acts against it. A
A represents myimproved valve, the same consisting 4 of a tlatplate a, of suitable dimensions, with atransverse disk, ai', at each end, of a size suited to the capacity of tlievalve-chamber, the said disks being provided with central trunnions, which enter bearings provided in `the end plates of the valv may properly oscillate.
As the plate a is set with its side opposite the induction-port B, it is obvious that itis subject to the full. pressure of' the water entering that port, which pressure, in an operative Water-engine, is liable to be too great for the strength of the plate to resist.
To take oli` aportion of such pressure, therefore, I cast between the disks a', and parallel with the plate c, two or moreV bars, c c, ush with the outer surface e-chamber, so that the valve `of the disks, and I leave a space, c', between the two bars opposite the centre of the plate a., and correspondentwith the induction-port, through which the Water may pass,`and spaces c" c", between the bars and the edges ofthe plate a, through which the water may pass `alternately to the cylinder C.
Nowit is clear `that the Waterwhich enters the induction-port, andlls the spaces between the plate a and bars c c, expends a portion of' its pressure upon the latter, all which portion the plate a is relieved of', and this is the end sought to be accomplished.
hat I claim as new, and desire to secure by Letters Patent, is
The valve A, consisting of the plate a and the bars c c, as and for the purpose described.
