IIMPR'VBIIIEIN'I.Il' VALVES FOR BTBAM-El'G-IRS.

The B ohedule nlptndtointhenlnttmPintlndmangpmofthe-sam.

Be it known that L'JOSEPH REIG bnque,' in the-county of Dubuque, and. State of Iowa, have invented a new and useful Improvement in Valves for Steam-Engines; and I do hereby declare that the' following is a full, clear, and eiactdesaniptiou thereof,-

whcll will enable others skilled-in theart to make and use the same, reference being had to the accompanying drawings, forming pal-tof this specification, in which -Flg .1 is a longitudinal section of the apparatus, 'taken-along the'line B B', figs. 3, 4, ,and 7,;

.2 is a. longitudinal non of the me, taken' Figure 4, and 7i;

Figure 3 is a plano'f thomann valve; y

Figure 4 is' a plan of, the stationary port andvalve Figure 5 is a-plan of the bottom of the same.

Figure 6 is a' lan' of the-cylindcr-iisce, and' a heli-,

mental section o .steam-chest Figure 7 is a plan of the bottom of the small valve -Figure 8 isa cross-section of` the same.'

`Similar letters of reference' indicatev like parts.

The nature of my invention consists- First, in the arrangement by which steam being aden one side of the valve-piston, and the exhaust produced on theother, moves said .valve-pistou and the A valve.

' Second,

inthe arrangement byyvhich, when the valve, piston and the valve reach the required point, steam is admitted to' the 'opposite side of said valve-piston, to niet in'st .the same and thereby checks tbe motion of said piston and oil the "valve, and, at a desired point,l

stops them.

'lc enable others skilled in the art to make and unev my invention, I will proceed lto describeits construction and operation.

of a steamfengine cylinder, of 'ordinary three-portseonstruction, in which N is the main exhaustport, end n 'n' are the steam-ports.

. ab is the steam-chest.

v Jl', the cover, with a `steam-opening, m.. dis the main valve, arranged as shown in the drawing, andforming, with the pistou f f', one andthe same piece, or they may beananged separately. lt-s provided with three exhaust-ports, -1, 2, and 2', iig. 1,' and two steam-ports, 3 and 3', tlg. 2, and is bearing on the valve-face steam-tight, having sufficient room to travel the req'uired distance.

IBushings t'and couplin piston f and j',

ton, and is he h is a port j being the packing-rings for said pis* between the bushing and the'coupling, d valve-plate, resting on the'lnain valve llt, and is held ill its position by ft is provided with'three exhaustthe steam-chest nir-Ants, of Dution, as represe gs cform the cylinders for ports, 4,14', and 5,g.1, and two steam-ports, 6 and 6', 'and a safetyLeup, 7, fig'. 2. 'y i is the small valve, provided with an exhaust-cup, .8, iig. 1,- and is movedby the rod K, passing through tbe st nflin Ainox I. v A

Figures and 10will` serve tc illustrate one method of operating'tll'e valves, the first being a vertical section 'on'the line bb of iig. 10, and t-heilatter being an elevation of the devices used.

A lnoel rer-erm, s, shaped as a quadrant, and provided with' pills and' slotsl bb, is'iitted at one cud to pin c, so-as to turn freely-around i and yis connected, at the eis alsiitted to pin o,land turns freely on itat one end, andiseonnected by meansof'pin g of block-h to' the collar i', provided with the slot K' of lthe piston-:rod I (see application) at the other end, pin c being held in position by. the bracket Lbblted to the engine-flame;

When the piston-rod 1 moves in the direction W,

for trip-hammers and other devices. The operation of of my valve consists in the followh the position as it is represented 4in the drawing, steam' being admitted through openi steam-chest b, enters port 2', iig. l', and J1chamber c' :by iillng chamber c of the valve-cylinder, in consequence of whichthe main valve dw'ill remain in posinted'in' the drawing.

The steam at the same time enters, through steamfport u, into the main cylinder of v.the engine, and moves the main piston in the direction W, as mailed-by the nrmw, which, by reaching the propell point, will move rod K and the small valve opens steam-pmt 6 into 3', openingalso exhaust-port 2, in consequenceof which, stfm will' go out of the from where it may also be. carried cii by au exhaustpipe from valve-plate h, and from 5 into '1, and into the main exhausbpol't N.; while 4the steam that enters 6' into 3', and into the chamber c', will move the valvepiston f' iil the direction from A' to A, and the point Il of saidpiston f will move to the point 1*,thu's opening 'steam-port n', in putting steam-port 'n into'comlnuuication with exhaustf'port N, in consequence of which, a return motion' of the main piston of theengne will alsopin ll of the quadrant working the valve i by' hand, when the valve is 'used al, into 'the v of the valve-cylinder; it also enters port 3, iig. 2, therev This closes steam-,port 6 and exhausifport 1', andchamber c of the valve-cylinder, through 4 into 5, and.

` ng. 2, whereby port 4 tain propel' point, a'twhich rod "i, then 'other steam-porto open, and the operation will be Irepeated, and-thevalvev lwill movefrom A to A',`taking the position as represented inthe drawing. l v l The cup f, as represented in' figs. 2 and 5, having com- ".munica'tionwith :exhaust-port to act as. a safety-port.

,will remark here,

the side opposite `to that` to'giveto the steam, acting" against the piston,` Vsufficient time to check its own motion, without interfering' with or reducing the steampassages; also, that the motion in regard to speed of the valve-pistou, may be regulated by the size of the' exhaustport 1,

and that the small valve i may be operated by the engine itself', or by'hand.

Having thus desoribedmy invention,

I claim as new,
